Abstract:

Objective To investigate changes and clinical significance of serum hydrogen sulfide (H2S) in patients with osteoporosis. Methods A total of 128 patients with osteoporosis admitted to our hospital were used as the osteoporosis group, and another 110 patients with low back pain in our hospital during the same period were selected as the control group. The Asian Osteoporosis Self-screening Tool (OSTA) was used to screen for osteoporosis risk by measuring bone mineral density in the lumbar spine (L1-4) and bilateral femoral neck with dual energy X-ray spectrometer. Five mL of fasting venous blood was collected from all patients after admission. Serum H2S, alkaline phosphatase (ALP), bone specific alkaline phosphatase (BALP), serum phosphorus, serum calcium, parathyroid hormone (iPTH), CTX, N-terminal propeptide of type 1 procollagen (P1NP), cross-linking C-terminal peptide of urinary 1 collagen (P1CP) and special sequence of carboxy-terminal peptide of type Ⅰ collagen (β-CTX) were detected. Pearson correlation analysis was conducted to analyze the correlation between serum H2S and bone metabolic markers in patients with osteoporosis. Results Compared with the control group, the bone mineral density of lumbar vertebra and femoral neck decreased, the serum H2S concentration decreased, the serum ALP, BALP, serum osteocalcin, P1NP, P1CP and iPTH concentration decreased, and the β-CTX level increased in the osteoporosis group (P<0.05). Serum H2S was positively correlated with ALP, BALP, serum osteocalcin, P1NP, P1CP and iPTH in patients with osteoporosis, but negatively correlated with β-CTX (P<0.05). Conclusion The serum level of H2S is significantly decreased in patients with osteoporosis. The detection of H2S is helpful to evaluate the bone metabolism in patients.
