The Impact of Type 2 Diabetes Mellitus on the Markers of Osteoporosis (Sclerostin and CTRP3) in Postmenopausal Women: A Comparative, Observational, Study

Abstract

Background In the present study, our goal was to assess the impact of type 2 diabetes mellites (T2DM) on osteoporosis markers (sclerostin and CTRP3) among postmenopausal women, and whether sclerostin and CTRP3 can be used as early biomarkers of osteoporosis/osteopenia in T2DM patients. Methods In a comparative, observation, study, a total of 30 postmenopausal women with osteoporosis/osteopenia and T2DM were included, as well as 30 non-diabetic women with osteoporosis/osteopenia. Thirty age and sex-matched healthy women were included as control groups. The enzyme-linked immunosorbent assay (ELISA) was used to assess the serum levels of sclerostin and CTRP3. Results A total of 90 women were included in the present study (30 patients per group). The serum CTRP3 was significantly lower in the DM-OST (3.45 ± 3.5 ng/dL) and OST (9.15 ± 3.65 ng/dL) groups than the control group (16.80 ± 0.55 ng/dL; p < 0.001); likewise, the serum sclerostin was higher in the DM-OST (109.95 ± 28.96 pmol/L) and OST (51.52 ± 23.18 pmol/L) than the control group (11.22 ± 1.21 pmol/L; p < 0.001). Notably, the serum CTRP3 was significantly lower and sclerostin was significantly higher in the DM-OST group than the OST group (p < 0.001)). In the DM + OST and OST groups, the serum CTRP3 correlated positively with BMD of lumbar spines, left femur, and left forearm. Serum CTRP3 was associated with lower risk of osteoporosis (OR) and diabetes (OR) in postmenopausal women. In addition, the serum sclerostin was associated with higher risk of osteoporosis (OR) and diabetes (OR) in postmenopausal women. Conclusion The present study provides a novel evidence about the impact of T2DM on osteoporosis biomarkers, serum CTRP3 and sclerostin. The results indicated that women with combined T2DM and osteoporosis/osteopenia exhibited more dysregulation in both biomarkers than women with osteoporosis/osteopenia. alone. Thus, serum CTRP3 and sclerostin can be used as biomarkers for early detection of osteoporosis in diabetic patients.

“…The results of the statistical analysis in table (1) for FBS showed there is no an important difference between the healthy groups and the osteoporosis without diabetes group, and this is identical with the work in the study [33], while there is an important difference between the healthy individuals and osteoporosis with diabetes group that is also ensured in the following studies [34,35].…”
