Comparison of effectiveness and safety of high-dose native vitamin D versus active vitamin D in the treatment of hypoparathyroidism / 中华内分泌代谢杂志

ABSTRACT

Objective@#To investigate the effectiveness and safety of high-dose native vitamin D versus active vitamin D by retrospective analysis of clinical data in patients with non-surgical hypoparathyroidism (ns-HP) in our hospital.@*Methods@#ns-HP patients with stable therapeutic schedule in recent three years were included. According to the vitamin D agents used, patients were divided into three groups active vitamin D group, native vitamin D group, and mixed vitamin D group. The effectiveness was evaluated by analysis of markers including post-treatment serum calcium, incidence of hypocalcemia, hypocalcemic symptoms and signs. The safety was evaluated in various groups by analyzing incidences of hypercalcemia and hypercalciuria, glomerular filtration rate, percentage of thiazide diuretic use, nephrocalcinosis or renal stone.@*Results@#Patients in active vitamin D group were more likely to experience episodes of hypocalcemia compared with those in native group (32.94%±21.46% vs 24.86%±10.1%, P<0.05). No significant differences in other indexes for assessing effectiveness and safety were found among three groups (P>0.05).@*Conclusions@#Under the circumstance of regular follow-up, both high-dose native vitamin D and active vitamin D could treat ns-HP effectively and safely. Native vitamin D may be better in maintaining eucalcemia and reducing incidence of hypocalcemia compared with active vitamin D.
