Background Bone is thought to be the reservoir of the human lead burden, and vitamin D is associated with bone turnover. We aimed to explore whether exposure to lower 25-hydroxy vitamin D (25(OH)D) levels was associated with higher blood lead levels (BLLs) by increasing the bone turnover rate in individuals with type 2 diabetes. Methods A total of 4103 type 2 diabetic men and postmenopausal women in Shanghai, China, were enrolled in 2018. Their 25(OH)D, β-C-terminal telopeptide (β-CTX), N-MID osteocalcin and procollagen type 1 N-peptide (P1NP) levels were detected. Their BLLs were determined by atomic absorption spectrometry. Mediation analyses were performed to identify the possible role that bone turnover played in the underlying mechanisms. Results In both the men and postmenopausal women, all three bone turnover markers were inversely associated with 25(OH)D and positively associated with the BLL (all P < 0.01) after adjusting for age, current smoking habits, metabolic parameters, duration of diabetes, vitamin D intake, and use of anti-osteoporosis medication. In the mediation analyses, none of the direct associations between 25(OH)D and BLL was significant for the three bone turnover markers, but all three bone turnover markers were found to be significant mediators of the indirect associations between 25(OH)D and BLL. Conclusion The association between vitamin D and BLL was fully mediated by bone turnover markers in type 2 diabetic patients (mediation effect). This finding suggested that vitamin D may protect against blood lead exposure from the bone reservoir by decreasing bone turnover in individuals with type 2 diabetes.

Background: Individuals with diabetes mellitus are at increased risk of metabolic bone disease due to decrease in bone strength and quality. Several bone turnover markers like serum procollagen type I N propeptide (P1NP) and serum osteocalcin are powerful tools for studying osteoporosis and fracture risk across population to provide diagnostic and prognostic information of bone health. The aim of this study was to recognize possible correlation of levels of serum P1NP and osteocalcin in type-2 diabetic (T2DM) postmenopausal women as compared to healthy postmenopausal women.Methods: The study included 100 proven cases of type-2 diabetic postmenopausal women with age matched healthy postmenopausal women as controls. P1NP, osteocalcin, and other relevant parameters were measured. Differences between diabetics and controls were analyzed.Results: The body mass index was higher in diabetic group as compared to controls. The HbA1c% was (6.94±1.43) in diabetic group and (5.57±1.21) in non-diabetics. Low serum level of 25 (OH) D was observed both in diabetic and non-diabetic groups but significantly lower in T2DM. Procollagen type 1 N propeptide was lower in diabetic group (37.59±17.20 ng/mL) as compared to non-diabetic (52.14±24.82 ng/mL). Osteocalcin was lower (15.64±8.06 ng/ml) as compared to non-diabetic group (21.85±9.12 ng/ml). Lower osteocalcin and P1NP levels found in this study suggests slower bone metabolism with reduced bone formation in postmenopausal diabetics.Conclusions: Serum procollagen type 1 N propeptide and osteocalcin in postmenopausal diabetic women were lower as compared to non-diabetic group.

The aim of this study was to evaluate differences in bone metabolism by calculating markers of bone turnover (C-terminal telopeptide and osteocalcin) with type 2 diabetes and patients in diabetic peripheral neuropathy patients compared with those without diabetic peripheral neuropathy.
