Bone Metabolism and Fracture Risk in Diabetes Mellitus

Individuals with Type 1 diabetes mellitus (T1DM) and type 2 diabetes mellitus (T2DM) are at increased risk for fragility fractures. Bone mineral density (BMD) is decreased in T1DM but often normal or even elevated in T2DM when compared with age-matched non-DM populations. However, bone turnover is decreased in both T1DM and T2DM. The pathophysiologic mechanisms leading to bone fragility is multifactorial, and potentially leads to reduced bone formation, altered bone microstructure and decreased bone strength. Interestingly, different antidiabetic treatments may influence fracture risk due to effects on glycemic control, triggering of hypoglycemic events or osteoblastogenesis.

Differences in the Insulin Resistance Levels Measured by HOMA-IR between Patients with Erosive and Non-Erosive Gastroesophageal Reflux Disease

Background Insulin resistance is the core of Metabolic Syndrome which carries a high risk for cardiovascular events. Insulin resistance had been reported to be higher in GERD patients than subjects without GERD, specifically in erosive esophagitis. Objective. To compare the degree of insulin resistance, using HOMA-IR index, between erosive and non-erosive reflux disease. Methodology A cross-sectional study of 84 adult patients with GERD symptoms was conducted. The subjects were recruited consecutively between January 2017 and April 2017 at Cipto Mangunkusumo National Hospital in Jakarta. Gastroesophageal Reflux Disease Questionnaire (GERDQ) was used for subject recruitment. Homeostatic model assessment-insulin resistance (HOMA-IR) index was used to evaluate insulin sensitivity. Esophageal erosions were diagnosed using upper gastrointestinal endoscopy. Bivariate analysis was used to determine HOMA-IR difference between esophagitis and non-esophagitis group. Results The median of HOMA-IR in all subjects was 1.46 (0.32-13.85). Mann-Whitney test revealed that HOMA-IR index was higher in patients with erosive esophagitis [median 1.74 (0.35-13.85)] than those without erosive esophagitis [median 1.21 (0.32-10.78)] (p=0.05). Conclusion Insulin resistance is significantly higher in gastroesophageal reflux disease patients with esophageal erosions than in those without esophageal erosion.
