What is the approach in heriditary hemochromatosis?
Therapeutic phlebotomy and chelation therapy are the primary options for iron removal.
What is the management approach of secondary iron overload.
Address the underlying cause (e.g., alcohol use disorder) to stop iron loading.
Consider iron removal on a case-by-case basis.
What are the indications for therapeutic phlebotomy?
First-line treatment for hereditary hemochromatosis (including asymptomatic patients)
Consider in patients with secondary iron overload (e.g., for patients with symptomatic porphyria cutanea tarda)
What are the contraindications for therapeutic phlebotomy?
Inability to tolerate the procedure (e.g., due to anxiety)
Low hemoglobin (e.g., due to iron-loading anemia)
Conditions sensitive to fluid shifts (e.g., end-stage liver disease, congestive heart failure)
Describe the therapeutic regimen of therapeutic phlebotomy.
Initial phase: blood removed weekly
Maintenance phase: blood removed 3–4 times per year
List indications for iron chelation therapy.
First-line treatment for secondary iron overload due to iron-loading anemia
Consider for hereditary hemochromatosis refractory to therapeutic phlebotomy and patients with contraindications to phlebotomy.
What are chelating agents used?
deferoxamine, deferasirox, or deferiprone
What are important considerations concerning iron chelation therapy?
Significant risk of adverse effects
E.g., renal toxicity, hepatic toxicity, retinopathy, ototoxicity, neutropenia, agranulocytosis, gastrointestinal bleed, rash
What should be checked prior to iron chelation therapy?
Check renal function prior to administration of chelating agents because of the risk of nephrotoxicity and renal accumulation.
Mnemonic chelating drugs.
Drugs that delete iron (Fe) in hemochromatosis: deFeroxamine, deFerasirox, deFeriprone
What are the indications for liver transplantation?
Decompensated cirrhosis
Hepatocellular carcinoma
List dietary changes to consider.
Advise avoidance of iron and vitamin C supplements —> Vitamin C increases intestinal iron absorption.
Encourage strict avoidance of alcohol.
No need to reduce dietary iron
Describe the patient counseling.
Early treatment of iron overload may:
Improve fatigue and skin hyperpigmentation
Reverse early organ damage (e.g., elevated liver chemistries, early cardiomyopathy)
Increase life expectancy
