[Aetiological spectrum of hyperferritinemia]

Area of Science:

• Clinical Medicine
• Biochemistry
• Hematology

Background:

• Elevated serum ferritin levels can indicate various underlying health conditions, including liver disease, renal disease, and infections.
• Understanding the spectrum of causes for hyperferritinemia is crucial for accurate diagnosis and patient management.

Purpose of the Study:

• To investigate the etiological spectrum of elevated serum ferritin levels in a large university hospital setting.
• To compare findings with existing literature and explore potential associations between specific causes and ferritin levels.

Main Methods:

• Retrospective review of medical records for 98 patients with serum ferritin levels exceeding 600 microg/l.
• Data collected between November 15, 2003, and January 15, 2004.
• Patients were recruited from hepatology, gastroenterology, hematology, and internal medicine departments.

Main Results:

• The most frequent causes of hyperferritinemia were non-HIV systemic infections (23.8%), hematological diseases (16.1%), alcoholism (11.2%), and malignancies (9.8%).
• Chronic renal failure, liver diseases, hemochromatosis, and systemic inflammatory diseases accounted for 4.2-5.2% of cases.
• Serum ferritin levels ranged from 600 to over 1500 microg/l, with no significant etiological difference across ferritin level groups.

Conclusions:

• Non-HIV infections and malignancies are the leading causes of high serum ferritin.
• Chronic renal failure is a less significant contributor to hyperferritinemia, likely due to the widespread use of erythropoietin reducing transfusion needs.
• Further research can refine understanding of hyperferritinemia's diverse origins.
