From the Guidelines
The management plan for a patient with iron overload, folate deficiency, and abnormal liver function tests presenting with nausea should prioritize therapeutic phlebotomy as the first-line treatment to reduce iron burden, as recommended by the most recent guidelines 1. The patient's iron level of 217, iron saturation of 79, and ferritin of 2902 indicate significant iron overload, which is likely contributing to liver dysfunction and possibly nausea.
- The folate deficiency, with a level of 2.8, should be addressed with folic acid supplementation, 1-5 mg daily orally, until levels normalize, typically for 1-3 months, then reassess.
- The nausea may be addressed with antiemetics such as ondansetron 4-8 mg orally every 8 hours as needed or metoclopramide 10 mg orally before meals.
- Liver function should be monitored with comprehensive metabolic panels every 2-4 weeks initially.
- Alcohol abstinence is essential, and hepatotoxic medications should be avoided, as recommended by the guidelines 1.
- A low-iron diet is recommended, avoiding iron-fortified foods and vitamin C supplements with meals, to minimize further iron accumulation.
- Regular monitoring of serum ferritin, transferrin saturation, folate levels, and liver enzymes is crucial to assess treatment efficacy.
- Phlebotomy should be performed weekly or biweekly, with a target serum ferritin level of 50-100 lg/L, as recommended by the guidelines 1.
- The patient's history of alcohol abuse and abnormal liver function tests (ALT of 108 and AST of 134) suggests the need for close monitoring of liver function and adjustment of the treatment plan as needed.
- The patient's MCV of 112 and MCH of 38 may indicate a macrocytic anemia, which could be related to the folate deficiency, and should be monitored during treatment.
- The guidelines recommend avoiding vitamin C supplements, especially before iron depletion, and restricting alcohol intake during the iron depletion phase of treatment 1.
- The patient's Coley’s vasectomy history is not directly relevant to the management of iron overload, folate deficiency, and abnormal liver function tests.
- The most recent guidelines from 2022 1 provide the best evidence for the management of hemochromatosis and iron overload, and should be followed to optimize patient outcomes.

From the Research
Diagnostic Testing Modalities
The patient's presentation with iron overload, folate deficiency, and abnormal liver function tests, along with symptoms of nausea, requires a comprehensive diagnostic approach. The following tests and evaluations can be considered:
- Complete blood count (CBC) to assess for anemia and other blood cell abnormalities 2
- Iron panel, including ferritin, iron levels, total iron-binding capacity, and transferrin saturation to evaluate iron overload 3, 4
- Liver function tests, including ALT and AST, to assess for liver damage 4, 5
- Folate and vitamin B12 levels to evaluate for deficiencies 6, 2
- Magnetic resonance imaging (MRI) to quantify hepatic iron deposition and assess for liver damage 4, 5
- Genetic testing for hereditary hemochromatosis, including HFE gene mutations 4, 5
- Liver biopsy to assess for liver fibrosis and cirrhosis 4, 5
Differential Diagnosis
The patient's presentation with iron overload, folate deficiency, and abnormal liver function tests can be caused by various conditions, including:
- Hereditary hemochromatosis 3, 4, 5
- Secondary iron overload due to hematologic disorders, iatrogenic causes, or chronic liver diseases 4
- Folate deficiency due to dietary deficiency, malabsorption, or increased demand 6, 2
- Liver disease due to alcohol abuse, viral hepatitis, or other causes 4, 5
Management Plan
The management plan for the patient will depend on the underlying cause of the iron overload, folate deficiency, and abnormal liver function tests. The following treatments can be considered:
