| Summary: | Context: Conventional treatment of hypoparathyroidism with calcium, Vitamin D analogs, and thiazide diuretics is often suboptimal, and these patients have poor quality of life. Teriparatide (parathyroid hormone 1–34 [PTH (1–34)]), an amide of PTH, is widely available for the use in osteoporosis; however, its use in hypoparathyroidism is limited. Aims: The aim of this study is to evaluate the efficacy of PTH (1–34) in the treatment of patients with hypoparathyroidism. Settings and Design: This was a prospective, open-label interventional study in a tertiary care hospital of Indian Armed Forces. Subjects and Methods: All patients with hypoparathyroidism presented to the endocrinology outpatient department were included and were exhibited injection PTH (1–34) 20 μg twice daily that was gradually reduced to 10 μg twice daily along with calcium, active Vitamin D (alfacalcidol), and hydrochlorothiazide. Oral calcium and alfacalcidol doses were also reduced to maintain serum calcium within normal range. The quality of life (QOL) score was calculated using RAND 36 QOL questionnaire at baseline and termination of the study. Statistical Analysis Used: Paired t-test was used to calculate pre- and post-treatment variables. Results: Eight patients (two males) were included in this study having mean age of 35.8 years. PTH (1–34) treatment led to the improvement in serum calcium (6.81–8.84 mg/dl), phosphorous (5.8–4.2 mg/dl), and 24 h urinary calcium excretion (416–203.6 mg). Parameters of QOL showed the improvement in overall QOL, physical performance, energy, and fatigue scores. No major adverse events were noted. Conclusions: Treatment of hypoparathyroidism with PTH (1–34) leads to improvement in calcium profile, reduction in hypercalciuria, and improvement in QOL, whereas it is safe and well tolerated.
