Association of Pseudohypoparathyroidism and Autoimmune Polyglandular Syndrome: Causal or Coincidental?

Abstract

Pseudohypoparathyroidism (PHP) is a state of parathyroid hormone resistance and is characterised by low serum calcium, and elevated serum phosphate and parathyroid hormone level. Association of PHP with autoimmune disorders is rare and seldom reported in the literature. Here we describe a case of PHP who subsequently developed multiple autoimmune disorders (type 3 polyglandular autoimmune syndrome), which has not been reported so far.
