[Endocrine complications of genetic hemochromatosis]

The authors report the prevalence and severity of endocrine complications in a cohort of 115 patients suffering form genetic hemochromatosis and followed since two decades. Already 40% of them had developed diabetes at the time of diagnosis of hemochromatosis, which was made at the age of 50 +/- 12 years (m +/- SD). Hypogonadism was evidenced in 42% of the patients. In most of them, it was considered as secondary to pituitary lesions as assessed by GnRH tests. No other endocrine complications, in particular thyroid disease, were evidenced during follow up. On the other hand, it was also of interest to note that liver cirrhosis was observed in 52% of the patients at the time of hemochromatosis diagnosis. A relationship between cirrhosis, diabetes and hypogonadism was also assessed in these patients. We conclude to the still high prevalence of endocrine complications in genetic hemochromatosis.
