Abstract
BACKGROUND: In hereditary haemochromatosis (HH), the thyroid gland is the site of substantial iron deposition. However, there have been relatively few reported cases of thyroid dysfunction in HH. AIM: To evaluate the prevalence of thyroid disorders in a large group of patients with HH. METHODS: A variety of endocrine investigations were undertaken including thyroid function tests and thyroid antibody studies. RESULTS: A total of 154 consecutive patients (123 male, 31 female) were studied. One case of primary hypothyroidism was identified, giving a prevalence of 0.6%. Subclinical hypothyroidism was identified in two females, giving a prevalence of 1.3%. Iatrogenic hypothyroidism was identified in two other cases. No case of hyperthyroidism was identified. CONCLUSION: Thyroid dysfunction is an uncommon occurrence in patients with HH.
