Abstract

AIM:

Leuprolide acetate is a gonadotropin-releasing hormone (GnRH) analogue frequently used in the treatment of central precocious puberty. Research is currently taking place into its effects on endocrine systems. The aim of this study is to investigate the effect of leuprolide acetate on vitamin D and bone mineral density.

METHODS:

Twenty-three children diagnosed with central precocious puberty and receiving leuprolide acetate therapy for at least 12 months, and a control group of 17 healthy children were enrolled. In the study group, calcium, phosphorus, alkaline phosphatase, parathormone and 25-hydroxy vitamin D levels and bone mineral density were measured. The results were compared with those of the control group.

RESULTS:

25-Hydroxy vitamin D levels in the study and control groups were 15.17 ± 7 mg/dL and 22.2 ± 6.1 mg/dL, respectively (p < 0.05). In terms of bone mineral density, osteopenia was determined in 13 (56.5%) patients in the study group and osteoporosis in one (4.3%), while osteopenia was identified in seven patients in the control group, with no osteoporosis being identified (p > 0.05).

CONCLUSION:

Gonadotropin-releasing hormone agonists may have an adverse effect on bone health. They may exhibit these effects by impacting on vitamin D levels. These levels should be periodically monitored in patients receiving treatment, and vitamin D support should be given in cases where the deficiency is identified.
