Risk factors, fractures, and management of pregnancy-associated osteoporosis: a retrospective study of 14 Turkish patients

Abstract

Pregnancy-associated osteoporosis (PAO) is a rare but painful disease. The current study aimed to investigate the demographic and clinical features, risk factors, treatment options, and outcomes of Turkish patients with PAO. In our retrospective, cross-sectional, and descriptive study the time to PAO diagnosis was 3.6 months. Pain and loss of height were detected in 78.6% and 28.6% of patients, respectively. As such, 60.6% of patients reported fractures at the thoracic area, 30.3% at the lumbar area, and 9.1% at the sacral area. While 14.3% of patients had optimal vitamin D status during pregnancy, 64.3% had vitamin D deficiency, and 21.4% had vitamin D insufficiency. Of the patients, 21.4% received anticoagulant therapy during their pregnancy. Dual X-ray absorptiometry scans revealed that osteoporosis was predominantly in the trabecular bone (L1–L4 Z-score –2.9, Femur Z score –2.19). Management options included supplements of calcium with vitamin D (93%), weaning the baby (79%), specific treatments for osteoporosis (64%), use of a supportive corset (50%), and exercise (21%), respectively. In addition, after delivery, 35.7% of patients were administered denosumab, 21.4% bisphosphonate, and 7.1% were given teriparatide. Data of the clinical features, treatments, and outcomes of PAO may contribute to early detection and management.
