[Idiopathic hypoparathyroidism with celiac disease--diagnostic and therapeutic problem]. / Idiopatická hypoparatyreóza s celiakií--diagnostické a lécebné problémy.

A middle-aged woman developed gradually diseases where most probably the common denominator is an autoimmune process. The authors describe the clinical condition persisting for seven years, where hypoparathyroidism was associated with coeliac disease which did not respond to dietary measures. Malabsorption was manifested by a selective block for calcium absorption from the gut. The impaired conversion of vitamin D2 to D3 is of interest; it has obviously a multifactorial etiology. The main problem is the patient's tendency to respond by tachyphylaxis to oral vitamin D administration. The only effective therapeutic procedure apart from those listed is so far parenteral administration of vitamin D3, calcitrol.
