Coeliac disease and primary hyperparathyroidism: an association?

Abstract

Primary hyperparathyroidism may present with non-specific symptoms, and this may be one reason why patients with coeliac disease fail to improve despite compliance with a gluten-free diet. Seven case reports of primary hyperparathyroidism due to sporadic adenoma occurring in a series of 310 patients with coeliac disease are presented, highlighting the importance of looking for this condition in this population group. A prevalence of primary hyperparathyroidism of 2.3% in this series suggests a significant association between hyperparathyroidism and coeliac disease; most studies have indicated a prevalence of 3 in 1000 in the general population, although one study found that it may be as high as 21 in 1000 in women aged 55-75 years. The average age of patients in our series was 59 years and all but one were women. Further studies are needed to establish a possible association between primary hyperparathyroidism and coeliac disease.
