Bone Health After Metabolic and Bariatric Surgery: Osteometabolism Biomarkers, Bone Mineral Density, and Microarchitecture
Abstract
Objective: The effects of metabolic and bariatric surgery on bone health still require further investigation. Osteometabolism biomarkers, bone microarchitecture (BM), and mineral density (BMD) of patients who have undergone Roux-en-Y gastric bypass (RYGB) within 2-5 years from surgery were compared to non-surgical age-, sex-, and BMI-matched controls.
Methods: This cross-sectional study included 39 patients following RYGB (BG: aged = 39 ± 5 years, BMI = 42.2 ± 3.8 kg/m2) and 21 controls (CG). Circulating levels of albumin, calcium, phosphorus, magnesium, 25(OH) vitamin D, parathyroid hormone (PTH), carboxy-terminal telopeptide of type 1 collagen (CTX-1), and amino-terminal propeptide of type 1 procollagen (P1NP) were assayed. BMD and BM were assessed by dual-energy X-ray absorptiometry (DXA) and three-dimensional high-resolution peripheral quantitative computed tomography system (HR-pQCT).
Results: BG presented with higher circulating phosphorus, PTH, CTX-1, and P1NP and lower 25(OH) vitamin D compared to CG. DXA parameters did not differ between groups. However, HR-pQCT revealed significant derangements in BM (trabecular thickness, cortical bone density, and outer trabecular volumetric BMD) in BG. BG showed tibia-specific trabecular microarchitecture impairment, while sex and BMI showed the expected associations with BM measures.
Conclusions: RYGB was associated with detrimental effects on osteometabolism biomarkers, as well as on density and structural parameters of BM.…
How strong is the evidence?
Evidence Hub reads this as a clinical trial, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 39 participants or records.
