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 .
