title: [Clinical characteristics of adult-onset primary hypoparathyroidism: a retrospective analysis of 200 cases].
abstract: Objective:To study the clinical characteristics of primary hypoparathyroidism in adults.Methods:The clinical data of 200 cases with adult-onset primary hypoparathyroidism in Peking Union Medical College Hospital during December 1987 to December 2015 were collected and analyzed retrospectively. Among them, 128 cases were followed up for a median period of 3 years.Results:The major manifestations at their first visits were tetany and numbness in the distal extremities(81.5%, 163/200 and 62.0%, 124/200). Thirty-two percent of the cases (62 cases) had history of seizures, and 60.9%(98/161) and 74.4%(96/129) of them were with intracerebral calcifications and cataracts, respectively.Most of subjects(155/200)had more than one year delay in diagnosis. Hypercalciuria occurred in 67.2%(86/128) of the cases during the follow-up. No significant differences in the clinical characteristics and biochemical markers between the hypercalciuria subjects and the non-hypercalciuria subjects. Renal nephrocalcinosis or stones were found in 6.5%(5/77) of the cases, and kidney function decreased in 6.6%(6/91) of the patients. Kidney function was negatively associated with age and duration of disease.Conclusions:The predominant manifestations of primary hypoparathyroidism in adults included tetany and numbness in the distal extremities and seizures. It is often misdiagnosed. Calcium supplement combined with vitamin D or its metabolites effectively relieve clinical symptoms and signs. The serum and urinary calcium levels should be monitored frequently to reduce renal complications.
