RESUMO
ABSTRACT Objective: This study evaluated the effects of combination therapy of curcumin and alendronate on BMD and bone turnover markers in postmenopausal women with osteoporosis. Subjects and methods: In a randomized, double-blind trial study, 60 postmenopausal women were divided into three groups: control, alendronate, and alendronate + curcumin. Each group included 20 patients. Total body, total hip, lumbar spine and femoral neck BMDs were measured by dual-energy X-ray absorptiometry (DXA) at baseline and after 12 months of therapy. Bone turnover markers such as bone-specific alkaline phosphatase (BALP), osteocalcin and C-terminal cross-linking telopeptide of type I collagen (CTx) were measured at the outset and 6 months later. Results: Patients in the control group suffered a significant decrease in BMD and increased bone turnover markers at the end of study. The group treated with only alendronate showed significantly decreased levels of BALP and CTx and increased levels of osteocalcin compared to the control group. The alendronate group also showed significant increases in the total body, total hip, lumbar spine and femoral neck BMDs at the end of study compared to the control group. In the curcumin + alendronate group, BALP and CTx levels decreased and osteocalcin levels increased significantly at the end of study compared to the control and alendronate groups. BMD indexes also increased in four areas significantly at the end of study compared to the control and alendronate groups. Conclusion: The combination of curcumin and alendronate has beneficial effects on BMD and bone turnover markers among postmenopausal women with osteoporosis. Arch Endocrinol Metab. 2018;62(4):438-45

The study of trend of Risedronate 10 mg/day in menopausal women with a high level of resorptive bone marker (Betacrosslaps, CTx) by the following bone markers:Bone alkaline phosphatase (formation marker) total alkaline phosphatase (TAlP), NMID osteocalcin, undercarboxylated osteocalcin (UcOC) and procollagen type 1 carboxyl propeptides (PICP). Risedronate does not suppress bone resorption deeply that enhances the bone recovers quickly after withdrawal. The level of undercarboxylated osteocalcin was increased after one year of treatment; it may be a sign of vitamin K2 deficiency. The bone alkaline phosphatase was decreased at the end of 12 months and Procollagen type 1 carboxyl propeptides (PICP) of twelfth month changed significantly compared to the sixth months of treatment (p=0.001) The once week 70 mg/week group also changed of CTx the same as daily dose group.
