Background

Phlebotomy (therapeutic bleeding) is a controlled removal of a large volume (usually a pint or more) of blood.  It is used mainly to reduce blood volume, red cell mass and iron stores.  Therapeutic phlebotomy may be indicated for hemochromatosis, polycythemia vera, porphyria cutanea tarda, and polycythemia secondary to arterio-venous fistulae, cyanotic congenital heart disease or cor pulmonale.

Therapeutic phlebotomy is used to remove excess iron and maintain low normal body iron stores in patients with hemochromatosis.  According to guidelines from the Hemochromatosis Management Working Group (Barton et al, 1998), therapeutic phlebotomy should be initiated in men with serum ferritin levels of 300 ug/L or more and in women with serum ferritin levels of 200 ug/L or more, regardless of the presence or absence of symptoms.  Typically, therapeutic phlebotomy consists of
  1. removal of 1 unit (450 to 500 ml) of blood weekly until the serum ferritin level is 10 to 20 ug/L, and
  2. maintenance of the serum ferritin level at 50 ug/L or less thereafter by periodic removal of blood.
Hyperferritinemia attributable to iron overload is resolved by therapeutic phlebotomy.  When applied before iron overload becomes severe, this treatment also prevents complications of iron overload, including hepatic cirrhosis, primary liver cancer, diabetes mellitus, hypogonadotrophic hypogonadism, joint disease, and cardiomyopathy.  In patients with established iron overload disease, weakness, fatigue, increased hepatic enzyme concentrations, right upper quadrant pain, and hyperpigmentation are often substantially alleviated by therapeutic phlebotomy.

Serum iron and ferritin concentrations are frequently elevated in patients with chronic viral hepatitis.  Pilot studies suggested that HCV-infected patients with elevated concentrations of iron in the blood and liver are less likely to respond to interferon, and that the response could be enhanced with iron reduction.  However, randomized controlled clinical trials of therapeutic phlebotomy for HCV treatment have not found significant improvements in sustained virologic response with phlebotomy plus interferon (IFN) compared to IFN alone (Fonatana et al, 2000; Di Bisceglie et al, 2000).

In a meta-analysis of randomized controlled trials (RCTs), Desai and colleagues (2008) compared phlebotomy and IFN to IFN alone for the treatment of chronic hepatitis C (CHC).  The Medline database and Cochrane registry of controlled trials were searched using the key words "phlebotomy" and "treatment of hepatitis C."  Reference lists of review articles discussing the interaction between iron and CHC, and prospective RCTs comparing phlebotomy plus IFN therapy to IFN alone were searched to identify additional RCTs that compared phlebotomy plus IFN to IFN alone.  Peto odds ratios with their 95 % confidence intervals (CI) and Forrest plots were generated for each variable to assess the relationships among the studies that had provided that information.  Statistical analysis was performed using Comprehensive Meta-Analysis version 2.0.  A total of 6 prospective RCTs were identified: all used sustained viral response (SVR) as an endpoint.  The 3 largest RCTs excluded patients with cirrhosis.  Two RCTs specifically included only patients with either high ferritin or high hepatic iron content.  Interferon treatment regimes varied.  Length of treatment varied between 6 and 12 months.  The phlebotomy plus IFN group and the IFN group did not differ with respect to the percentage of patients with cirrhosis or genotype 1.  Sustained viral response was attained in 50/182 (27 %) patients in the phlebotomy plus IFN group, compared to 22/185 (12 %) patients in the IFN group.  Peto odds ratio for SVR in phlebotomy plus IFN group was 2.7; 95 % CI: 1.6 to 4.5, p < 0.0001.  All 5 RCTs published in manuscript form showed a trend towards a benefit from the phlebotomy plus IFN in attaining SVR, and the results of the meta-analysis were not dependent on any single RCT, since excluding any single RCT did not change the results.  The authors stated that phlebotomy appeared to enhance the efficacy of non-pegylated IFN monotherapy for CHC, but more research was required to confirm this. Problems associated with the limited volume of data and clinical and methodological heterogeneity between the studies were acknowledged and addressed by the investigators in the discussion section of the review. The doubtful applicability of this evidence to pegylated IFN was also highlighted. Moreover, the authors stated that confirmation of this will require RCT with detailed pre-treatment iron studies and appropriately powered to demonstrate a statistically significant benefit. The authors stated that adequately powered RCTs with detailed pre-treatment iron studies should be considered to evaluate phlebotomy as an adjunct to pegylated IFN, with or without ribavirin. As a priority, they recommended research among selected genotype one patients unable to tolerate ribavirin.

Guidelines from the American Gastroenterological Association (Dienstag and McHutchison, 2006) on management of hepatitis C concluded that clinical trials have failed to demonstrate the efficacy of phlebotomy in patients with chronic HCV infection, and that phlebotomy cannot currently be recommended as a treatment for HCV infection.

In a review on evidence-based approach for the treatment of adults with sickle cell disease, Lottenberg and Hassell (2005) noted that reports and case series indicated that repeated phlebotomy to lower the hemoglobin (Hb) level and induce iron deficiency can reduce the frequency of painful episodes in selected patients with high steady state Hb levels.

Bouchair et al (2000) reported the findings of sickle cell disease patients who suffered from frequent painful crises and were submitted to phlebotomies in order to reduce hospitalization days due to pain.  These patients had an Hb level equal to or above 9.5 g/dL.  A total of 7 sickle cell disease patients (4 sickle cell anemia, 3 sickle Hb C disease), aged 4 to 24 years, were submitted to sequential phlebotomies during periods from 18 months to 4 years.  The number of hospitalization days for crises was considered.  The volumes and frequencies of phlebotomies were adjusted according to the patients ages, the Hb concentrations and the serum ferritin levels.  A total of 144 hospitalization days were recorded in the 7 patients in the year preceding the treatment.  During the study period, the annual numbers of hospitalization days were respectively 20, 5, 6 and 1.  Mean Hb concentration was 10.7 g/dL before phlebotomies and 8.8 to 9.2 g/dL during the 4 years of treatment.  Mean corpuscular volume, mean corpuscular Hb concentration and serum ferritin were also reduced.  The volume of phlebotomies was 116 to 390 ml/kg/year according to the patients.  The striking decrease of the number of hospitalization days for all the patients suggests a closed relationship between therapy and clinical improvement.  The mechanism of this effect is probably multi-factorial:
  1. the concentration of Hb level is known to influence the blood viscosity and its decrease always improved rheology in sickle cell disease patients;
  2. the mean corpuscular Hb concentration is a critical factor concerning the HbS molecule polymerization in sickle cell disease, and its slight reduction may have an important biological effect.
The authors observed these two biological modifications in their patients and suggested that they mediate the clinical effects.  The iron deficiency induced by phlebotomies has no evident deleterious consequence either on height and weight in the children or on intellectual performance in any patients.

Rombos and colleagues (2002) noted that sickle cell disease patients who acquire iron deficiency may experience a degree of amelioration from painful crises in terms of frequency, severity, and duration.  This observation prompted these researchers to identify the potential utility of iron load reduction in the management of this disease. A total of 13 sickle cell patients not ameliorated by conventional treatment entered a weekly venesection protocol (phlebotomy).  Hematological values and painful crises of all degrees of severity were recorded and compared to those of the last 12 months before venesection for each case separately (historical controls).  A decrease was noted in the frequency and intensity of several types of painful crises.  Reduction of iron load by venesection seems to be a simple, safe, side-effect-free, and efficient way of preventing and ameliorating to a large extent painful crises in sickle cell disease.

Markham et al (2003) stated that marked variability is a keynote in the disease course of patients with Hb SC (Hb SC) and hemoglobin S/beta(+)-thalassemia (Hb S/beta(+)-thal), with some patients having a frequency of complications and painful episodes similar to patients with homozygous sickle cell (Hb SS) disease.  One possible explanation is that the higher hematocrit in these syndromes may contribute to an increase in blood viscosity, leading to vaso-occlusive pain episodes as well as an increased incidence of thrombo-embolic complications and retinopathy.  These investigators presented a patient with Hb SC disease with an excellent baseline functional status who developed splenic infarction at a high altitude.  Following splenectomy, the patient developed a sustained increase in hematocrit, an increase in the frequency of painful episodes, as well as new-onset dizziness and malaise.  The authors initiated a therapeutic phlebotomy program in order to lower the hematocrit to pre-splenectomy values, as well as to induce iron deficiency.  Repeated phlebotomy resulted in a dramatic decrease in symptoms.  This patient no longer requires narcotic analgesics for pain, has resolution of constitutional symptoms, and has not required further hospitalizations for vaso-occlusive pain crises.  The correlation between symptoms and hematocrit levels supports the importance of blood viscosity in contributing to this patient's symptoms.  A trial of phlebotomy to reduce viscosity in patients with higher hematocrit values should be considered as an intervention for symptomatic patients with sickle cell disease.

The American Association for the Study of Liver Diseases' clinical practice guideline on "Diagnosis and management of hemochromatosis" (Bacon et al, 2011) provided the following recommendations:

  • Patients with hemochromatosis and iron overload should undergo therapeutic phlebotomy weekly (as tolerated).  Target levels of phlebotomy should be a ferritin level of 50 to 100 µg/L.
  • In the absence of indicators suggestive of significant liver disease (ALT, AST elevation), C282Y homozygotes who have an elevated ferritin (but less than 1,000 µg/L) should proceed to phlebotomy without a liver biopsy.
  • Patients with end-organ damage due to iron overload should undergo regular phlebotomy to the same endpoints as indicated above.
  • During treatment for hereditary hemochromatosis, dietary adjustments are unnecessary.  Vitamin C supplements and iron supplements should be avoided.
  • Patients with hemochromatosis and iron overload should be monitored for re-accumulation of iron and undergo maintenance phlebotomy.  Target levels of phlebotomy should be a ferritin level of 50 to 100 µg/L.
  • The guideline developers recommend treatment by phlebotomy of patients with non-HFE iron overload who have an elevated hepatic iron concentration.

Barbui and colleagues (2011) presented a review of critical concepts and produced recommendations on the management of Philadelphia-negative classical myeloproliferative neoplasms, including monitoring, response definition, first- and second-line therapy, and therapy for special issues.  Key questions were selected according the criterion of clinical relevance.  Statements were produced using a Delphi process, and 2 consensus conferences involving a panel of 21 experts appointed by the European LeukemiaNet (ELN) were convened.  Patients with polycythemia vera (PV) and essential thrombocythemia (ET) should be defined as high-risk if age is greater than 60 years or there is a history of previous thrombosis.  Risk stratification in primary myelofibrosis (PMF) should start with the International Prognostic Scoring System (IPSS) for newly diagnosed patients and dynamic IPSS for patients being seen during their disease course, with the addition of cytogenetics evaluation and transfusion status.  High-risk patients with PV should be managed with phlebotomy, low-dose aspirin, and cytoreduction, with either hydroxyurea or interferon at any age.  High-risk patients with ET should be managed with cytoreduction, using hydroxyurea at any age.  Monitoring response in PV and ET should use the ELN clinico-hematologic criteria.  Corticosteroids, androgens, erythropoiesis-stimulating agents, and immunomodulators are recommended to treat anemia of PMF, whereas hydroxyurea is the first-line treatment of PMF-associated splenomegaly.  Indications for splenectomy include symptomatic portal hypertension, drug-refractory painful splenomegaly, and frequent red blood cells transfusions.  The risk of allogeneic stem-cell transplantation-related complications is justified in transplantation-eligible patients whose median survival time is expected to be less than 5 years.

Tefferi (2012) stated that PV and ET are myelo-proliferative neoplasms (MPN) primarily characterized by erythrocytosis and thrombocytosis, respectively.  Other disease features include leukocytosis, splenomegaly, thrombo-hemorrhagic complications, vasomotor disturbances, pruritus, and a small risk of disease progression into acute myeloid leukemia or myelofibrosis.  Almost all patients with PV harbor a JAK2 mutation.  When PV is suspected, the presence of a JAK2 mutation confirms the diagnosis and its absence, combined with normal or increased serum erythropoietin level, excludes the diagnosis.  Differential diagnosis of ET had to include chronic myelogenous leukemia and pre-fibrotic myelofibrosis.  A JAK2 mutation is found in approximately 60 % of patients with ET.  Current risk stratification in PV and ET is designed to estimate the likelihood of thrombotic complications: high-risk is defined by the presence of age greater than 60 years or presence of thrombosis history; low-risk is defined by the absence of both of these 2 risk factors.  Presence of extreme thrombocytosis (platelet count greater than 1,000 × 10(9)/L) might be associated with acquired von Willebrand syndrome (AvWS) and, therefore, risk of bleeding.  Risk factors for shortened survival in both PV and ET include advanced age, leukocytosis, and history of thrombosis.  Survival is near-normal in ET and reasonably long in PV.  The 10-year risk of leukemic/fibrotic transformation is less than 1 %/1 % in ET and less than 3 %/10 % in PV.  In contrast, the risk of thrombosis exceeds 20 %.  The main goal of therapy is therefore to prevent thrombo-hemorrhagic complications and this is effectively and safely accomplished by the use of low-dose aspirin (PV and ET), phlebotomy (PV), and hydroxyurea (high-risk PV and ET).  Treatment with busulfan or interferon-α is usually effective in hydroxyurea failures.  Screening for clinically significant AvWS is recommended before administrating aspirin in the presence of extreme thrombocytosis.

Lengfelder (2013) presented an overview on relevant topics of pathogenesis and diagnosis of PV.  The presently available treatment options in PV were discussed and recommendations for the clinical management were given.  The JAK2V617F mutation, a point mutation in the tyrosine kinase gene JAK2 (Janus Kinase 2), has emerged as a central feature in the pathogenesis of MPN.  Subsequently, the identification of several other mutated genes in MPN has shown that the pathogenesis is complex and that the JAK2V617F mutation is a critical, but not the only step leading to the uncontrolled proliferation in MPN including PV.  The diagnostic criteria of PV have been revised in 2008 and include the JAK2V617F mutation as one of the 2 major criteria of the disease.  This molecular diagnostic marker proves the clonality and facilitates the diagnosis of early and uncertain cases that remained sometimes undiagnosed in the past.  Main treatment aims are the reduction of thromboembolic events and the minimization of the risk of myelofibrosis and of acute leukemia.  The authors concluded that PV patients with low-risk of vascular complications should be treated with phlebotomy and low-dose acetylsalicylic acid.  High-risk patients should receive cytoreductive therapy with hydroxyurea or interferon alpha.   Studies with JAK inhibitors are presently ongoing.

An UpToDate review on “Prognosis and treatment of polycythemia vera” (Tefferi, 2013) states that “In subjects without active thrombosis and those not at risk for thrombosis (i.e., age of less than 60, no prior thrombosis), we recommend that the hematocrit be kept within the normal range via the use of serial phlebotomy, rather than by the use of myelosuppressive agents (Grade 1A).  Optimal control is to keep the hematocrit below 45 %in men and 42 % in women.  Since phlebotomy is effective in controlling PV by producing a state of relative or absolute iron deficiency, iron supplementation should not be given.  For patients at high risk for thrombosis (i.e., age of greater than 60, prior thrombosis), we recommend that treatment with phlebotomy be supplemented with the use of a myelosuppressive agent. (Grade 1B).  For this purpose we prefer the use of hydroxyurea rather than an alkylating agent, radioactive 32P, or interferon alpha.  If not otherwise contraindicated because of a history of major bleeding or intolerance, we suggest that aspirin be given to all patients (Grade 2C).  The appropriate dose is 75 to 100 mg/day.  Treatment with higher doses should be avoided”.

In a pilot study, Creange et al (2013) evaluated the concept that iron depletion (ID) induced by blood-letting and followed by recombinant human erythropoietin (rhEPO) administration could be a therapeutic strategy in progressive multiple sclerosis (PMS) and that it could be assessed by neurophysiological measurements.  In 4 patients with PMS, blood-letting was performed until ID was induced, and then rhEPO was administered (300 UI/kg/week).  The changes induced by the treatment were assessed by clinical scores, biological tests, and neurophysiological study of cortical excitability using transcranial magnetic stimulation techniques.  The treatment was well-tolerated except for muscle cramps and 1 popliteal vein thrombosis in a patient confined to chair.  Iron depletion was obtained within 28 weeks and was associated with endogenous production of EPO.  No blood-letting was further required during a 6-month period after introduction of rhEPO.  At the end of the follow-up (up to 1 year), fatigue and walking capacities tended to improve in 2 patients.  Neurophysiological changes were characterized by an increased cortical excitability, including a decrease of motor thresholds and an enhancement of intra-cortical facilitation and cerebello-thalamo-cortical inhibition.  The authors concluded that the combined ID-rhEPO therapy could authorize a prolonged administration of rhEPO in PMS patients, able to modify cortical excitability of the glutamatergic and gabaergic circuits.  Moreover, they stated that these preliminary data are encouraging to design a larger, controlled trial to assess the value of such a strategy to improve functional symptoms in PMS patients, and maybe to prevent axonal degeneration.

In a Cochrane review, Wang and Dwan (2013) evaluated risks and benefits of chronic blood transfusion regimens in people with sickle cell disease to prevent first stroke or recurrences.  These investigators searched the Cochrane Cystic Fibrosis and Genetic Disorders Group Trials Register, comprising references identified from comprehensive electronic database searches and hand-searches of relevant journals and conference proceedings.  Date of the latest search of the Group's Haemoglobinopathies Trials Register was January 28, 2013.  Randomized and quasi-randomized controlled trials comparing blood transfusion as prophylaxis for stroke in people with sickle cell disease to alternative or no treatment were selected for analysis.  Both authors independently assessed the risk of bias of the included trials and extracted data.  Searches identified 3 eligible randomized trials (n = 342).  The first 2 trials addressed the use of chronic transfusion to prevent primary stroke; the third utilized the drug hydroxycarbamide (hydroxyurea) and phlebotomy to prevent both recurrent (secondary) stroke and iron over-load in patients who had already experienced an initial stroke.  In the first trial (STOP) a chronic transfusion regimen for maintaining sickle hemoglobin lower than 30 % was compared with standard care in 130 children with sickle cell disease judged (through transcranial Doppler ultrasonography) as high-risk for first stroke.  During the trial, 11 children in the standard care group suffered a stroke compared to 1 in the transfusion group, odds ratio [OR] of 0.08 (95 % CI: 0.01 to 0.66).  This meant the trial was terminated early.  The transfusion group had a high complications rate, including iron over-load, allo-immunization, and transfusion reactions.  The second trial (STOP II) investigated risk of stroke when transfusion was stopped after at least 30 months in this population.  The trial closed early due to a significant difference in risk of stroke between participants who stopped transfusion and those who continued as measured by re-occurrence of abnormal velocities on Doppler examination or the occurrence of overt stroke in the group that stopped transfusion.  The third trial (SWiTCH) was a non-inferiority trial comparing transfusion and iron chelation (standard management) with hydroxyurea and phlebotomy (alternative treatment) with the combination end-point of prevention of stroke recurrence and reduction of iron over-load.  This trial was stopped early after enrolment and follow-up of 133 children because of analysis showing futility in reaching the composite primary end-point.  The stroke rate (7 strokes on hydroxyurea and phlebotomy, none on transfusion and chelation, OR of 16.49 (95 % CI: 0.92 to 294.84)) was within the non-inferiority margin, but the liver iron content was not better in the alternative arm.  The authors concluded that the STOP trial demonstrated a significantly reduced risk of stroke in participants with abnormal transcranial Doppler ultrasonography velocities receiving regular blood transfusions.  The follow-up trial (STOP 2) indicated that individuals may revert to former risk status if transfusion is discontinued.  The degree of risk must be balanced against the burden of chronic transfusions.  The combination of hydroxyurea and phlebotomy is not as effective as "standard" transfusion and chelation in preventing secondary stroke and iron over-load.  Moreover, they stated that ongoing multi-center trials are investigating the use of chronic transfusion to prevent silent infarcts, the use of hydroxyurea as an alternative to transfusion in children with abnormal transcranial Doppler ultrasonography velocities, and the use of hydroxyurea to prevent conversion of transcranial Doppler ultrasonography velocities from conditional (borderline) to abnormal values.

Du and colleagues (2014) evaluated the therapeutic effect of pricking blood therapy for migraine. These investigators searched all the original papers about pricking blood therapy for migraine in common databases as the Chinese National Knowledge Infrastructure Database (CNKI), Chinese Biomedical Library (CBM), Ovid, Science Direct, Socolar, and Sci Finder (1949 to 2012), Wanfang Data (1998 to 2012) and Foreign Medical Journal Service (FMJS, 1990 to 2012). The original articles were searched in accordance with a pre-defined standards (simple pricking blood treatment, or the pricking blood therapy was the principal approach), while those about other diseases (such as cerebrovascular disease, cervical spondylosis, etc.) evoked migraine, pricking blood used as a complementary therapy, case report, specialists' experience summary, reviews, surveys, news articles, animal studies were excluded. Then, a Meta-analysis was made by software Review Manager 5.1. A total of 11 clinical trial papers involving 826 cases of migraine were included in the present paper; 3 of them were high-quality researches, and the other 8 were low quality researches. Results of meta-analysis indicated that the therapeutic effect of the pricking blood therapy was significantly superior to that of non-bleeding therapies in relieving migraine [OR = 6.23, 95 % CI: 4.03 to 9.63, Z = 8.24, p < 0.00 001]. However, the poor symmetry of funnel plot suggested a risk of bias. The authors concluded that the pricking blood therapy is effective for relieving migraine, but larger sample clinical trials, particularly RCTs are definitely needed for confirming the conclusion.

Furthermore, UpToDate reviews on “Preventive treatment of migraine in adults” (Bajwa and Smith, 2015) and “Chronic migraine” (Garza and Schwedt, 2015) do not mention phlebotomy as a therapeutic option.

Hemoglobin SC Disease

Summarell and Sheehan (2016) stated that hydroxyurea is an excellent therapeutic agent for the pharmacological induction of fetal hemoglobin (HbF) in patients with sickle cell disease (SCD). However, all completed clinical trials of hydroxyurea have excluded patients with hemoglobin SC (HbSC) disease; HbSC differs significantly in pathophysiology from HbSS, as HbC does not sickle, but instead causes cellular dehydration which potentiates sickling of HbS.  Many severely affected HbSC patients have been placed on hydroxyurea on a case-by-case basis, but there are no large scale prospective data on safety or effectiveness of hydroxyurea in this subset of patients with SCD.  These investigators reported a case series of 14 pediatric patients with HbSC treated to maximum tolerated dose (MTD) with hydroxyurea.  Those who failed to show clinical improvement after at least 6 months at MTD were offered phlebotomy in addition to hydroxyurea; 5 out of 11 patients with HbSC who achieved MTD failed to demonstrate clinical improvement on hydroxyurea.  Of the 4 placed on dual hydroxyurea and phlebotomy therapy, all showed at least partial clinical improvement.  Percent dense red blood cells (%DRBC) were measured via an ADVIA hematology analyzer.  A marked rise in percent dense cells preceded clinical complications in 3 patients.  Dual therapy with hydroxyurea and phlebotomy may be an effective approach to patients with HbSC that do not experience improvement with hydroxyurea alone.  Monitoring of %DRBC may predict adverse events and aid in evaluating hydroxyurea compliance.  The authors concluded that large scale clinical trials are needed to evaluate the safety and effectiveness of hydroxyurea and hydroxyurea with phlebotomy in patients with HbSC disease.

Non-Alcoholic Fatty Liver Disease with Hyperferritinemia

Valenti  and colleagues (2012) stated that non-alcoholic fatty liver disease (NAFLD), defined by excessive liver fat deposition related to the metabolic syndrome, is a leading cause of progressive liver disease, for which accurate non-invasive staging systems and effective treatments are still lacking.  Evidence has shown that increased ferritin levels are associated with the metabolic insulin resistance syndrome, and higher hepatic iron and fat content.  Hyperferritinemia and iron stores have been associated with the severity of liver damage in NAFLD, and iron depletion reduced insulin resistance and liver enzymes.  These researchers noted that  Kowdley et al recently demonstrated in a multi-center study in 628 adult patients with NAFLD from the NAFLD-clinical research network database with central re-evaluation of liver histology and iron staining that the increased serum ferritin level was an independent predictor of liver damage in patients with NAFLD, and was useful to identify NAFLD patients at risk of non-alcoholic steatohepatitis and advanced fibrosis.  The authors concluded that these findings indicated that incorporation of serum ferritin level may improve the performance of non-invasive scoring of liver damage in patients with NAFLD, and that iron depletion (most frequently achieved by phlebotomy) still represents an attractive therapeutic target to prevent the progression of liver damage in these patients.

Kim and Oh (2016) stated that therapeutic phlebotomy is the preferred treatment for blood disorders in which the removal of RBCs or serum iron is the most efficient method for managing the symptoms and complications.  Therapeutic phlebotomy is currently indicated for the treatment of hemochromatosis, polycythemia vera, porphyria cutanea tarda, sickle cell disease, and NAFLD with hyperferritinemia.

Furthermore, an UpToDate review on “Approach to the patient with suspected iron overload “ (Schrier and Bacon, 2017) states that “In liver disease (e.g., viral hepatitis, alcoholic hepatitis, non-alcoholic steatohepatitis), injury to hepatocytes may cause an increase in serum ferritin despite normal total body iron stores … The major treatments for iron overload include phlebotomy for those without significant anemia … Removal of iron with a course of therapeutic phlebotomy (at least 5 to 6 phlebotomies) with normalization of the ferritin level”.

Therapeutic Phlebotomy for the Common Cold

Lee and colleagues (2017) stated that many people experience the common cold, but there is currently no special treatment.  For this reason, complementary and alternative medicine (CAM) therapies are used to improve the symptoms of the common cold.  Blood-letting therapy (BL) is a CAM therapy that has been used for over 2,000 years to treat various diseases.  However, few studies have provided evidence for the safety and efficacy of BL for the common cold.  This study aims to evaluate the safety and effectiveness of BL for the common cold.  A total of 11 databases will be searched for studies conducted through June 2017.  These investigators will include RCTs assessing BL for the common cold.  All RCTs on BL or related interventions will be included.  Risk of bias will be assessed using the Cochrane Risk of Bias Assessment Tool, while confidence in the accumulated evidence will be evaluated using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) instrument.  The authors stated that they have presented a protocol for a systematic review of BL for the common cold; they hoped that this study will form the basis to conduct additional research and provide evidence for the use of BL for the common cold.

Chronic Urticaria

Yao and colleagues (2019) stated that many trials have reported that blood-letting therapy is effective for treating chronic urticaria.  There are currently no systematic reviews of blood-letting therapy for chronic urticaria.  In a systematic review and meta-analysis of RCTs, these researchers examined the safety and effectiveness of blood-letting therapy for the treatment of chronic urticaria.  Disease activity control was evaluated as the primary outcome.  Response rate, recurrence rate, and adverse events (AEs) were assessed as secondary outcomes.  A total of 7 studies with 512 subjects were included; 1 trial showed a significant difference between blood-letting therapy plus medicine and medicine alone in disease activity control (mean difference [MD] 0.67; 95 % CI: 0.03 to 1.31; p = 0.04); 6  trials (372 subjects) showed a significant difference between blood-letting therapy and pharmacological medication in response rate (risk ratio [RR] 1.10; 95 % CI: 0.97 to 1.26; p = 0.15); 2 studies (170 subjects) showed a significant difference between blood-letting therapy plus pharmacological medication and pharmacological medication in response rate (RR 1.34; 95 % CI: 1.10 to 1.63; p  =0.003); 2 studies (126 subjects) reported a statistically significant difference between blood-letting therapy and pharmacological medication in recurrence rate.  No serious AEs related to blood-letting therapy were reported.  The authors stated that although the data showed potential effectiveness of blood-letting therapy in chronic urticaria, the quality of the evidence was low, and there were many aspects that can be improved in future studies.  These researchers stated that large-scale, multi-center RCTs with proper outcome measurements and long-term follow-up are needed to provide convincing proof.

The authors stated that this study had several drawbacks.  First, the sample size of included studies was small.  Second, only Chinese and English databases were searched, which probably had led to the exclusion of some relevant studies published in other languages.  Third, the combination of different area selection and duration types of blood-letting therapy may have caused significant clinical heterogeneity.  A study about how to achieve the most effective blood-letting therapy may also need to be conducted in the future.  Besides, the Global Allergy and Asthma European Network (GA2LEN) recommended patient-reported outcomes (PROs) and health-related quality of life (HR-QOL) in patients with urticarial.  PROs have been recommended to be reported for RCTs.  The included trials were all published in Chinese and all used comprehensive outcomes, such as response rate, as primary outcomes, lacking for universal, and PROs.  The comprehensive outcomes, which combine the clinical symptoms, signs, and laboratory examinations as one outcome, were not internationally recognized and could not reflect the characteristics of interventions.  Using comprehensive outcomes was also the common problems of most RCTs of traditional Chinese medicine published in Chinese.

Hypertension

In a systematic review and meta-analysis of RCTs, Xiong and colleagues (2019) examined the safety and efficacy of blood-letting therapy (BLT) in the treatment of hypertension.  These researchers carried out a comprehensive electronic and manual bibliographic searches in Cochrane Central Register of Controlled Trials, Excerpt Medica Database (EMBASE), PubMed, China National Knowledge Infrastructure, Chinese Scientific Journal Database, Chinese Biomedical Literature Database, and Wanfang Database to identify RCTs in which hypertensive patients were treated with BLT or BLT plus anti-hypertensive drugs (BPAD) against placebo, no treatment or anti-hypertensive drugs.  The Cochrane Risk Assessment Tool was used to assess the methodological quality of trials.  The Review Manager 5.3 software was used for meta-analysis.  A total of 7 RCTs with 637 hypertensive patients from 1989 to 2017 were identified.  Compared with anti-hypertensive drugs, blood pressure (BP) was significantly reduced by BLT (RR = 1.21, 95 % CI: 1.01 to 1.44, p = 0.03; heterogeneity: p = 0.06, I2 = 60 %) and BPAD (RR = 1.25, 95 % CI: 1.02 to 1.53, p = 0.03; heterogeneity: p = 0.01, I2 = 71 %).  Moreover, a significant improvement in Chinese medicine syndrome by BLT (RR = 1.32; 95 % CI: 1.14 to 1.53, p = 0.0002; heterogeneity: p = 0.53, I2 = 0 %) and BPAD (RR = 1.47; 95 % CI: 1.06 to 2.04, p = 0.02; heterogeneity: p = 0.13, I2 = 56 %) was identified.  The reported adverse effects were well-tolerated.  The authors concluded that although some positive findings were identified, no definite conclusions regarding the safety and efficacy of BLT as complementary and alternative approach for the treatment of hypertension could be drew due to the generally poor methodological design, significant heterogeneity, and insufficient clinical data.  These researchers stated that further rigorously designed trials are needed to confirm these findings.

Furthermore, UpToDate reviews on “Treatment of resistant hypertension” (Townsend, 2020), “Treatment of hypertension in older adults, particularly isolated systolic hypertension” (Egan, 2020) and “Overview of hypertension in adults” (Basile and Bloch , 2020) do not mention phlebotomy as a management / therapeutic option.

Individuals Receiving Testosterone Therapy

Chin-Yee et al (2017) noted that polycythemia is the most common adverse effect of testosterone replacement therapy (TRT) and may predispose patients to adverse vascular events.  Current Canadian guidelines recommend regular laboratory monitoring and discontinuing TRT or reducing the dose if the hematocrit (HCT) exceeds 54 % (hemoglobin [Hb] of greater than or equal to 180 g/L).  This threshold has been interpreted by some physicians and patients to indicate the need for phlebotomy or blood donation while on TRT.  These investigators reviewed all male blood donors in Southwestern Ontario at Canadian Blood Services from December 2013 to March 2016 who self-identified or were found on donor screening to be on TRT; Hb concentration was measured at the time of donation or clinic visit and with each subsequent appointment in repeat donors.  These researchers identified 39 patients on TRT who presented for blood donation over a 2-year period.  The mean Hb level at all clinic visits was 173 g/L (range of 134 to 205 g/L; n = 108); Hb concentrations of 180 g/L or more (calculated HCT of greater than or equal to 54%) were measured at 25 % of appointments.  Of the 27 repeat donors, 12 (44 %) had persistently elevated Hb levels (greater than or equal to 180 g/L) at subsequent donations.  The authors concluded that Hb concentrations were elevated in donors on TRT, and significant numbers had Hb levels above those recommended by current guidelines.  These data also suggested that repeat blood donation was insufficient to maintain HCT of below 54 %.  These findings raised concerns regarding the persistent risk of vascular events in these donors, especially when coupled with the misperception by patients and health care providers that donation has reduced or eliminated the risks of TRT-induced polycythemia.

Rotker et al (2018) stated that a variety of methods for TRT exist, and the major potential risks of TRT have been well established.  The risk of developing polycythemia secondary to exogenous testosterone (T) has been reported to range from 0.4 % to 40 %.  Implantable T pellets have been used since 1972, and secondary polycythemia has been reported to be as low as 0.4 % with this administration modality.  However, these investigators’ experience has suggested a higher rate.  They conducted an institutional review board (IRB)-approved, single-center, retrospective chart review (2009 to 2013) to determine the rate of secondary polycythemia in 228 men treated with subcutaneously implanted testosterone pellets.  Kaplan-Meyer failure curves were used to estimate time until the development of polycythemia (HCT of greater than 50 %).  The mean number of pellets administered was 12 (range of 6 to 16).  The mean follow-up was 566 days.  The median time to development of polycythemia whereby 50 % of patients developed polycythemia was 50 months.  The estimated rate of polycythemia at 6 months was 10.4 %, 12 months was 17.3 %, and 24 months was 30.2 %.  The authors concluded that the incidence of secondary polycythemia while on T pellet therapy may be higher than previously established.  Moreover, these researchers stated that any patient who developed HCT of greater than 50 % was advised to obtain phlebotomy.

Van Buren et al (2020) examined therapeutic phlebotomy (TP) requests for testosterone replacement therapy (TRT) and highlighted the impact to a blood center (BC) or service that provides TP for individuals on TRT.  These researchers carried out a review of TP requests for individuals on TRT at their BC over a 3-year period from 2014 through 2016, as well as the total number of TP collections.  Total TPs during 2014, 2015, and 2016 were 475, 500, and 569, respectively.  Annual TP collections for patients on TRT were 193, 212, and 239, respectively.  TRT patients with TP orders increased 71.4 % during this period.  After discontinuation of TP services for TRT at their BC, 32 % continued to donate as volunteer blood donors at their BC.  The authors concluded that their BC observed increased TP requests for patients on TRT from 2014 through 2016.  These findings suggested that individuals on TRT may be presenting to BCs as volunteer blood donors to avoid charges for TP.

Furthermore, an UpToDate review on “Testosterone treatment of male hypogonadism” (Snyder, 2021) states that “The hematocrit should be measured after 3 to 6 months after initiating testosterone treatment and then yearly.  If it increases above the upper limit of normal, a cause should be sought, and if none is found, the dose of testosterone should be decreased or stopped.  The Endocrine Society guidelines suggest stopping therapy if the hematocrit increases to ≥ 54 %.  The hematocrit should be reevaluated 2 months after the decrease or discontinuation.  If the hematocrit normalizes, a lower dose of testosterone should be continued or restarted.  If the hematocrit cannot be kept below the upper limit of normal, even when the serum testosterone concentration is at the low end of the normal range during testosterone treatment, the patient should be evaluated for hypoxia and sleep apnea.  If no treatable cause is found, phlebotomy can be considered”.

Non-Hereditary Hemochromatosis Iron Overload

Adjarov et al (1984) reported that in 74 patients with porphyria cutanea tarda, 11 (14.9 %) cases of beta-thalassemia were found.  The incidence of beta-thalassemia in porphyrics is not greater than in non-porphyrics and it appeared that beta-thalassemia is not a factor triggering the development of porphyria cutanea tarda.  The authors stated that phlebotomy is a convenient method for porphyria cutanea tarda combined with beta-thalassemia.

De Gobbi et al (2000) noted that juvenile hemochromatosis is a rare genetic disorder that causes iron overload.  Clinical complications, which include liver cirrhosis, heart failure, hypogonadotropic hypogonadism and diabetes, appear earlier and are more severe than in HFE-related hemochromatosis.  Thus, this disorder requires an aggressive therapeutic approach to achieve iron depletion.  These investigators reported the case of a young Italian female with juvenile hemochromatosis who was unable to tolerate frequent phlebotomy because of co-existent ss-thalassemia trait.  The patient was successfully iron-depleted by combining phlebotomy with recombinant human erythropoietin.

Barton e al (2006) treated 4 white adults (1 man, 3 women) who had iron overload associated with daily ingestion of iron supplements for 7, 15, 35, and 61 years, respectively.  These researchers carried out HFE mutation analysis to detect C282Y, H63D, and S65C in each patient; in 2 patients, HFE exons were sequenced.  In 2 patients, direct sequencing was performed to detect coding region mutations of TFR2, HAMP, FPN1, HJV, and ALAS2.  Patients 1 to 4 ingested 153, 547, 1,341, and 4,898 g of inorganic iron as supplements.  Patient 1 had hemochromatosis, HFE C282Y homozygosity, and beta-thalassemia minor.  Patient 2 had spherocytosis and no HFE coding region mutations.  Patient 3 had no anemia, a normal HFE genotype, and no coding region mutations in HAMP, FPN1, HJV, or ALAS2; she was heterozygous for the TFR2 coding region mutation V583I (nt 1,747 G-->A, exon 15).  Patient 4 had no anemia and no coding region mutations in HFE, TFR2, HAMP, FPN1, HJV, or ALAS2.  Iron removed by phlebotomy was 32.4, 10.4, 15.2, and 4.0 g, respectively.  There was a positive correlation of log(10) serum ferritin and the quantity of iron removed by phlebotomy (p = 0.0371).  Estimated absorption of iron from supplements in patients 1 to 4 was 20.9 %, 1.9 %, 1.1 %, and 0.08 %.  The authors concluded that the clinical phenotypes and hemochromatosis genotypes of adults who developed iron overload after ingesting iron supplements over long periods were heterogeneous.  These investigators stated that therapeutic phlebotomy was feasible and effective, and would prevent complications of iron overload.

Barbieri et al (2009) described the first 2 cases of porphyria cutanea tarda associated with beta-thalassemia major.  The clinical course of 2 women affected by beta-thalassemia major was complicated by the onset of porphyria cutanea tarda.  Both patients were also suffering from hepatitis C virus infection, iron overload and anemia.  These researchers discussed the role performed by some of these conditions in triggering overt porphyria cutanea tarda.  An improvement of the clinical and biochemical picture of porphyria cutanea tarda in both patients was obtained with chloroquine therapy given that their chronic anemia did not permit phlebotomy.

Inati et al (2017) stated that iron overload is well documented in patients with beta-thalassemia major, and patients who have undergone hematopoietic stem cell transplantation (HSCT) remain at risk as a result of pre- and immediate post-HSCT transfusions.  In a prospective, randomized, 1-year clinical trial that compared the safety and efficacy of the once-daily oral iron chelator deferasirox versus phlebotomy for the treatment of iron overload in children with beta-thalassemia major following HSCT.  Patients (aged 12.4 years) received deferasirox (n = 12, 10 mg/kg/day starting dose) or phlebotomy (n = 14, 6 ml/kg/2 weeks) for 1 year.  In 2 and 5 patients, deferasirox dose was increased to 15 and 20 mg/kg/day, respectively.  Magnetic resonance imaging (MRI)-assessed liver iron concentration (LIC) decreased with deferasirox (mean 12.5 ± 10.1 to 8.5 ± 9.3 mg Fe/g dry weight [dw]; p = 0.0005 versus baseline) and phlebotomy (10.2 ± 6.8 to 8.3 ± 9.2 mg Fe/g dw; p = 0.05).  LIC reductions were greater with deferasirox than with phlebotomy for patients with baseline serum ferritin 1,000 ng/ml or higher (-8.1 ± 1.5 versus -3.5 ± 5.7 mg Fe/g dw; p = 0.048).  Serum ferritin and non-transferrin-bound iron also decreased significantly.  In 2 patients with severe cardiac siderosis, a clinically relevant improvement in myocardial T2* was observed, following phlebotomy and deferasirox therapy (n = 1 each).  Adverse effects with deferasirox were skin rash, gastro-intestinal (GI) upset, and increased liver function tests (all n = 1), while those for phlebotomy were difficulty with venous access (n = 4) and distress during procedure (n = 1).  The authors concluded that parents of 13/14 children receiving phlebotomy wished to switch to deferasirox, with 1/14 being satisfied with phlebotomy.  The authors concluded deferasirox treatment or phlebotomy reduced iron burden in pediatric patients with beta-thalassemia major post-HSCT, with a manageable safety profile.

Gumus et al (2017) stated that the use of extended criteria donors who might have previously been deemed unsuitable is an option to increase the organ supply for transplantation.  These researchers presented a pediatric case of a successful liver transplantation from a donor with beta-thalassemia intermedia.  A patient, 6-year old girl, with a diagnosis of cryptogenic liver cirrhosis underwent deceased donor liver transplantation from a thalassemic donor.  Extreme hyper-ferritinemia was detected shortly after transplantation.  The most probable cause of hyper-ferritinemia was iron overload secondary to transplantation of a hemosiderotic liver.  Hepatocellular injury due to acute graft rejection might have contributed to elevated ferritin levels by causing release of stored iron from the hemosiderotic liver graft.  Iron chelation and phlebotomy therapies were started simultaneously in the early post-operative period to avoid iron-related organ toxicity and transplant failure.  Follow-up with monthly phlebotomies after discharge yielded a favorable outcome with normal transplant functions.  Thalassemia intermedia patients can be candidates of liver donors to decrease pre-transplant wait-list mortality.  After transplantation of a hemosiderotic liver, it is important to monitor the recipient in terms of iron overload and toxicity.  Early attempts to lower iron burden including chelation therapy and/or phlebotomy should be considered to avoid organ toxicity and transplant failure.

The American Association for the Study of Liver Diseases' clinical practice guideline on "Diagnosis and management of hemochromatosis" (Bacon et al, 2011) stated that the guideline developers recommended treatment by phlebotomy of patients with non-hereditary hemochromatosis (HFE) iron overload who have an elevated hepatic iron concentration.

Furthermore, an UpToDate review on “Approach to the patient with suspected iron overload” (Bacon and Kwiatkowski, 2021) states that “The major treatments for iron overload include phlebotomy for those without significant anemia, and chelation therapy for those with anemia”.

Acute Gouty Arthritis

Johnson (1999) noted that gout affects mostly men over 40 years of age, and occasionally, post-menopausal women.  This pattern coincides with the pattern of iron accumulation.  On the other hand, menstruating women are seldom afflicted by gout, because the monthly blood loss causes them to accumulate iron to a much lesser degree.  Gout involves 7 aspects.  First, uric acid (UA) over-production from increased purines in the diet.  Second, UA over-production from ATP degradation.  Third, UA over-production from increased de-novo synthesis of purines.  Fourth, UA over-production from increased DNA breakdown from cell damage.  Fifth, decreased UA elimination, caused by molybdenum and sulfur binding to copper in the kidneys.  Sixth, precipitation of sodium urate-iron crystals in the joints due to high ferritin and saturated transferrin and low CuZn-SOD and Cu-thionein in the joint.  Seventh, development of inflammation, triggered by tyrosine bonding to the sodium-urate-iron crystals and being transformed by tyrosine kinase.  Alcohol and iron greatly affect most of these aspects.  The author stated that phlebotomy is suggested as therapy for gout patients to eliminate the accumulated iron.  In addition, annual blood donation is recommended for men with a family history of gout to prevent iron accumulation and avoid gout.

Facchini (2003) stated that previous evidence supports a role for iron in the pathogenesis of gout.  For example, iron, when added to media containing urate crystals, stimulated oxidative stress with subsequent complement and neutrophil activation.  Conversely, iron removal inhibited these responses as well as urate-crystal-induced foot pad inflammation in rats in-vivo.  The author examined whether or not iron removal may improve the outcome of gouty arthritis (GA) in humans as well.  Quantitative phlebotomy was employed to remove iron in 12 hyperuricemic patients with GA and maintained their body iron at near-iron deficiency (NID) level (i.e., the lowest body iron store compatible with normal erythropoiesis and therefore absence of anemia).  During maintenance of NID for 28 months, gouty attacks markedly diminished in every patient, from a cumulative amount of 48 and 53 attacks per year before (year -2, -1), to 32, 11 and 7 during induction (year 0) and maintenance (year +1, +2) of NID, respectively.  During NID, attacks were also more often of milder severity.  The authors concluded that during a 28-month follow-up, maintenance of NID was found to be safe and beneficial in all patients, with effects ranging from a complete remission (CR) to a marked reduction of incidence and severity of gouty attacks.

Zhao et al (2009) examined a more effective therapy for acute GA (AGA).  A total of 60 cases were randomly divided into an observation group and a control group, 30 cases in each group.  On the basis of diet intervention, the observation group was treated with electro-acupuncture at local points combined with blood-letting puncture and cupping, and the control group with oral administration of Probenecid.  Their therapeutic effects were observed.  The effective rate was 96.7 % in the observation group, which was better than 86.7 % in the control group (p < 0.01).  After treatment, blood UA decreased significantly in the 2 groups (both p < 0.01), the observed group being lower than the control group (p < 0.01).  The authors concluded that on the basis of diet intervention, electro-acupuncture plus blood-letting puncture and cupping was a better therapy for AGA.

Zhang et al (2010) examined the therapeutic effect of blood-letting cupping plus herbal medicine for the treatment of AGA.  A total of 34 cases of AGA were treated by blood-letting cupping plus herbal medicine; 21 cases were cured, and 13 cases improved.  The authors concluded that the therapeutic effect of this therapy was satisfactory for AGA.

Zhu et al (2015) compared the differences in clinical effectiveness between pricking blood combined with moxibustion and Western medication (WM) for the treatment of AGA.  A total of 40 patients with AGA were randomly divided into a pricking blood combined with moxibustion group (a combination group) and a WM group, 20 cases in each group.  In the combination group, pricking blood was used at the most painful points of the red turgid and painful joint once every 3 days, a total 3 times; moxibustion was applied at the same joint for 15 to 20 mins, once-daily.  The moxibustion was adopted for 10 days.  In the WM group, 0.3 g ibuprofen was prescribed orally twice-daily for 10 days.  The changes of UA, high sensitivity C-reactive protein (hs-CRP), erythrocyte sedimentation rate (ESR) and the joint syndrome and symptom score before and after treatment were observed.  In the 2 groups, the UA, the hs-CRP, the ESR and the joint syndrome and symptom scores were lower than those before treatment (all p < 0.05).  After treatment, the UA, the ESR and the joint syndrome and symptom scores in the combination group decreased more apparently than those in the WM group (all p < 0.05).  The total effective rate in the combination group was 85.0 % (17/20) which was better than 75.0 % (15/20) in the WM group (p < 0.05).  The authors concluded that pricking blood combined with moxibustion could improve the joint symptoms more effectively and the effect was better than ibuprofen orally.

Fatima et al (2018) noted that iron could contribute to gouty inflammation by forming complexes with monosodium urate (MSU) crystals, stimulating oxidative stress through the generation of reactive oxygen species, and contributing to granulocyte and complement activation.  A decrease in gout flares following phlebotomy to attain NID levels in hyperuricemic patients is also suggestive of a role in gout.  These investigators also stated that maintenance of NID by depleting the levels via phlebotomy in patients with gout induces either complete or marked reduction in incidence and severity of gout flares in humans.

Charnow (2018) noted that previous research suggested a plausible link between iron and gout, and ferritin stores excess iron, and urate acts as an iron chelator.  Therefore, iron can increase the activity of xanthine oxidase, the sole enzymatic source of urate in human beings.  The investigator cited a study (Facchini, 2003) showing that use of phlebotomy to maintain NID levels in patients with hyperuricemia was associated with a marked decrease in the incidence and severity of gouty attacks.

Li et al (2022) noted that blood-letting therapy (BLT) is often used for the treatment of AGA; however, limited evidence-based reports exist on the safety and effectiveness of BLT.  In a systematic review and meta-analysis, these researchers examined the feasibility and safety of BLT in the treatment of patients with AGA.  They screen 7 databases from the date of establishment to July 31, 2020, irrespective of the publication source and language.  The included articles were examined for bias risk by using the Cochrane risk of bias assessment tool.  All statistical analyses were carried out with Review Manager 5.3.  A total of 12 studies entailing 894 subjects were included for the final analysis.  The meta-analysis revealed that BLT was highly effective in relieving pain (MD = -1.13, 95 % CI: -1.60 to -0.66, p < 0.00001), with marked alterations in the total effective (RR = 1.09, 95 % CI: 1.05 to 1.14, p < 0.0001) and curative rates (RR = 1.37, 95 % CI: 1.17 to 1.59, p < 0.0001).  Furthermore, BLT could dramatically reduce CRP level (MD = -3.64, 95 % CI: -6.72 to -0.55, p = 0.02).  Both BLT and WM produced comparable decreases in UA (MD = -18.72, 95 % CI: -38.24 to 0.81, p = 0.06) and ESR levels (MD = -3.01, 95 % CI: -6.89 to 0.86, p = 0.13).  Lastly, these investigators demonstrated that BLT was safer than WM in treating AGA (RR = 0.36, 95 % CI: 0.13 to 0.97, p = 0.04).  The authors concluded that BLT was effective in alleviating pain and decreasing CRP level in AGA patients with a lower risk of evoking adverse reactions.

Hyperferritinemia in Alcohol Liver Disease

An UpToDate review on “Approach to the patient with suspected iron overload” (Bacon and Kwiatkowski) does not mention phlebotomy as a therapeutic / management option for hyperferritinemia in alcohol liver disease.
