Hemosiderosis with diabetes mellitus in untransfused hemoglobin H disease

Abstract

A 37-year-old untransfused, non-drinking man with Hemoglobin H-CS disease presented with insulin-dependent diabetes mellitus, markedly elevated serum ferritin level, and marked iron deposition in hepatocytes. He did not carry either of the two common mutations of the HLA-H gene for hereditary hemochromatosis, namely, Cys282Tyr and His68Asp, nor did he have the associated HLA marker (HLA-A3, B7 nor B-14) for the disease. Patient with HbH disease should be monitored for iron overload.
