The aim of this study was to determine the effect of vitamin D deficiency on the RANKL/OPG ((Receptor Activator of Nuclear Factor Kappa B Ligand/Osteoprotegerin) ratio in the serum blood levels. Sixteen Wistar rats were divided into 2 groups: a control group (C) and an experimental group (E). The group C comprised of rats with average vitamin D levels, while vitamin D deficiency was induced in those of group E. A test period of 21 days was employed wherein two serum blood samples were obtained, at the baseline (day 0) and at day 21. Changes in RANKL andOPG levels were measured using Enzyme-linked immunosorbent assay (ELISA) kits. A statistically significant decrease of serum RANKL concentration and RANKL/OPG ratio on day 21 was seen in the experimental group compared to the control group. The serum RANKL levels and RANKL/OPG ratio in rats, were negatively affected by the deficiency of vitamin D.

Although observational studies have linked vitamin D deficiency to diabetes, it is unknown if taking vitamin D supplements can reduce the chance of developing type 2 diabetes mellitus (T2DM). The purpose of this systematic review is to determine whether vitamin D supplementation lowers the risk of type 2 diabetes. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were used to search for studies based on pre-established inclusion and exclusion criteria.

Fracture is an under-recognized but common complication of diabetes mellitus, with an incidence approaching twofold in type 2 diabetes mellitus (T2DM) and up to sevenfold in type 1 diabetes mellitus (T1DM) compared with that in the general population. Both T1DM and T2DM induce chronic hyperglycaemia, leading to the accumulation of advanced glycosylation end products that affect osteoblast function, increased collagen crosslinking and a senescence phenotype promoting inflammation. Together with an increased incidence of microvascular disease and an increased risk of vitamin D deficiency, these factors reduce bone quality, thereby increasing bone fragility.

Pediatric patients with sickle cell disease and vitamin D deficiency have worse clinical and laboratory outcomes. This study aims to quantify the prevalence of vitamin D deficiency in this population and identify possible risk factors for hypovitaminosis D by performing a cross-sectional study with children aged 3-18 years old with sickle cell disease. Sixty patients were evaluated, with a mean age of 10.

Targeting optimal glycemic control based on hemoglobin A1c (A1c) values reduces but does not abolish the onset of diabetic kidney disease and its progression to chronic kidney disease (CKD). This suggests that factors other than the average glucose contribute to the residual risk. Vitamin D deficiency and frequent episodes of acute hyperglycemia (AH) are associated with the onset of albuminuria and CKD progression in diabetes.

Primary hyperparathyroidism is treated surgically. Postoperatively, close monitoring of blood calcium levels is necessary to detect any hypocalcemia. Postoperative PTH assays can be performed within 24 hours to identify patients who will not develop permanent hypoparathyroidism.
