Haemachromatosis Flashcards
Patient presents with high ferritin.
Impression/DDx/Goals
Impression
Ferritin is an acute phase reactant, thus this most likely is representative of acute/chronic inflammatory condition (infection, alcoholism, diabetes, etc). However, persistently elevated/massively elevated ferritin likely is indicative of haemachromatosis.
Goals of management:
- Identify aetiology of elevated ferritin
- implement appropriate treatment and long-term management plan
- prevent organ dysfunction due to iron overload
What is Haemachromatosis?
Haemachromatosis:
- hereditary condition (HFE gene autosomal recessive)
- excessive iron absorption
- subsequent iron overload
- Common in northern Europeans
Iron overload complications:
- multiorgan damage (liver cirrhosis, skin hyperpigmentation, cardiomyopathy, diabetes, maliganncy, etc)
Haemachromatosis - History
History:
- Sx: infection, systemic illness, complications of chronic iron overload (HF symptoms, liver failure), other nonspecific sx
- PMHx: other medical conditions in explanation
- FamHx
- Medications
- SNAP
Haemachromatosis - Examination
Exam:
- Baseline obs
- vital signs
- systems review (cardio, abdo exams)
Haemachromatosis - Investigations
Investigations:
Bedside: ECG
Bloods: FBC, Iron studies, LFTs, BSL (T1DM), HBa1C, CRP
Imaging: MRI for Iron deposition (combination scans), US Elastography for cirrhosis [regular monitoring on a screening basis]
Other: Echo
Additional: Genetic testing for HFE gene mutations, bleed the homozygous patients.
Haemachromatosis: Management
Management:
Mainstay of treatment is regular phlebotomy to maintain low ferritin stores (50-150 depending on lab). Indicated in patients with persistently heightened ferritin >500. Frequency of Phlembotomy is tailored to patients clinical requirements.
Otherwise, patients can be managed expectantly if their risk of progression to iron overload is low.
Just need regular review period for FBC and iron studies to ensure appropriate iron stores are maintained.
Supportive
- avoidance of alcohol (liver damage)
- no need to reduce iron in the diet
