From the Guidelines
The patient's hematocrit (Hct) of 47.2% and hemoglobin (Hb) of 16.1 g/dL are not immediately concerning.
Key Points to Consider
- The patient's elevated ferritin level, despite normal iron, transferrin, and TIBC levels, suggests that the elevated ferritin may be due to inflammation or other non-iron related causes, as stated in the EASL clinical practice guidelines for HFE hemochromatosis 1.
- The patient's symptoms of dizziness and mild headache, exacerbated by certain head movements, are non-specific and do not directly point to hemochromatosis or iron overload.
- The American Association for the Study of Liver Diseases recommends using a combination of transferrin saturation (TS) and ferritin to diagnose hemochromatosis, rather than relying on a single test 1.
- The patient's normal blood pressure, prediabetes, and lack of other symptoms suggestive of organ involvement make it less likely that they have significant iron overload or hemochromatosis.
- The EASL clinical practice guidelines on haemochromatosis suggest that MRI can be helpful in detecting and quantifying iron overload, but it is not necessary in this case, given the patient's normal TS and lack of other risk factors 1.
Next Steps
- Further evaluation of the patient's elevated ferritin level, including checking for inflammation (e.g., CRP) and other potential causes of hyperferritinemia, as recommended by the EASL clinical practice guidelines for HFE hemochromatosis 1.
- Consider genetic testing for HFE mutations if the patient's ferritin level remains elevated and other causes of hyperferritinemia are ruled out, as recommended by the American Association for the Study of Liver Diseases 1.
From the Research
Hematological Parameters
- The patient's hematocrit (Hct) of 47.2% and hemoglobin (Hb) of 16.1 g/dL are within normal limits for a female adult 2, 3.
- Elevated ferritin levels can indicate iron overload or inflammation, but in this case, the patient's iron, transferrin, and total iron-binding capacity (TIBC) levels are normal, suggesting that the elevated ferritin may not be related to iron overload 2, 4.
Iron Status and Headache
- There is evidence to suggest that iron deficiency may be associated with headache and migraine, particularly in women 5.
- However, the patient's normal iron, transferrin, and TIBC levels, as well as the lack of other symptoms of iron deficiency, make it unlikely that iron deficiency is the cause of her headache 2, 6.
- The patient's elevated ferritin level may be related to inflammation or other factors, but its significance in relation to her headache is unclear 3, 5.
Diagnostic Considerations
- The diagnosis of iron deficiency anemia (IDA) depends on the applied biomarkers of iron deficiency, and transferrin saturation (TSAT) or ferritin when used alone may lead to diagnostic difficulties 6.
- Combining soluble transferrin receptor (sTfR)-log ferritin index and reticulocyte hemoglobin content (CHr) to evaluate iron-deficient erythropoiesis in patients with anemia, in addition to ferritin and TSAT, could contribute to improving the diagnosis of IDA in clinical practice 2, 6.
- However, in this case, the patient's normal iron, transferrin, and TIBC levels, as well as the lack of other symptoms of iron deficiency, make it unlikely that IDA is the cause of her headache 2, 6.
