The spectrum of clinical and subclinical endocrinopathies in treatment-naïve patients with celiac disease.

INTRODUCTION

Strong association exists between celiac disease and autoimmune endocrinopathies such as type I diabetes and hypothyroidism; there is a lack of data on the involvement of other endocrine organs such as pituitary-gonadal axis. Furthermore, there is lack of data on the spectrum of involvement of endocrine organs varying from organ autoimmunity to subclinical and clinical disease. We evaluated consecutive treatment-naïve patients with celiac disease (CeD) for clinical and subclinical endocrinopathies.

METHODS

Of 154 screened, 74 treatment-naïve patients with CeD were recruited. They underwent hormonal and/or functional assessment of beta cell of pancreas, thyroid gland, pituitary-gonadal axis, and parathyroid glands.

RESULTS

Of the 74 patients with CeD, 31 (41.9%) had at least one clinical or subclinical endocrinopathy and 9 (12.2%) had multiple endocrinopathies. Most common of them were clinical or subclinical type I diabetes and autoimmune thyroid disease. Interestingly, 8 (10.8%) patients also were found to have functional hypopituitarism and 7/54 (12.9%) having isolated hypogonadotropic hypogonadism.

CONCLUSIONS

Patients with CeD have high percentages of not only clinical endocrinopathy including pituitary-gonadal axis dysfunction but also subclinical endocrinopathy. Whether commencement of gluten-free diet will lead to reversal of subclinical endocrinopathies requires further follow up studies.
