Biologic Function

Major biologic function of activated vitamin D is to maintain normal blood levels of calcium and phosphorus, thus regulating bone mineralization. Research suggests that vitamin D may help in immunomodulation, regulating cell growth and 1,4 differentiation as well as some diverse unspecified functions. Overt vitamin D deficiency leads to hypocalcaemia, secondary hyperparathyroidism and increased bone turnover, which in prolonged and severe cases may cause rickets in children and osteomalacia in elderly....

ABSTRACT Background : Roux-en-Y gastric bypass patients can experience changes in calcium metabolism and hyperparathyroidism secondary to vitamin D deficiency. Aim : To evaluate nutritional deficiencies related to the calcium metabolism of patients undergoing gastric bypass with a 10-year follow-up. Method : This is a longitudinal retrospective study of patients submitted to Roux-en-Y gastric bypass at a multidisciplinary clinic located in the Brazilian southeast region. The study investigated the results of the following biochemical tests: serum calcium, ionized calcium, vitamin D, and parathormone (PTH). The generalized estimating equations (GEE) determined the nutritional deficiencies using a significance level of 5%. Results : Among the patients who finished the study (120 months), 82.86% (n=29) had vitamin D deficiency, and 41.94% (n=13) had high PTH. Postoperative time had a significant effect on PTH (p=0.0059). The percentages of patients with vitamin D, serum calcium, and ionized calcium deficiencies did not change significantly over time. Conclusion : One of the outcomes was vitamin D deficiency associated with secondary hyperparathyroidism. These findings reaffirm the importance of monitoring the bone metabolism of patients submitted to Roux-en-Y gastric bypass. HEADINGS: Calcium deficiency. Vitamin D deficiency. Secondary hyperparathyroidism.

INTRODUCTION: Obesity represents the major risk factor for development of insulin resistance during childhood and adolescents. In obesity, adipose tissue release free fatty acids, various hormones, and cytokines, resulting in insulin resistance. This study aimed to establish the correlation between vitamin D deficiency and the incidence of insulin resistance in obese children. DESIGN AND METHOD: This analytical cross-sectional study was arranged from December 2019 - February 2020 included 96 students aged 11 - 17 years old from junior and senior high school who met the criteria for obesity in Makassar. The study subjects were parted into two groups, obese children with vitamin D deficiency (levels of 25-hydroxyvitamin D ≤ 20 ng/ml) and obese children without vitamin D deficiency group (levels of 25-hydroxyvitamin D > 20 ng/ml). Data were analyzed using univariate and bivariate analysis. RESULTS: The frequency of insulin resistance in obese children with vitamin D deficiency was 28 (54.9%), while obese children without vitamin D deficiency was 10 (22.2%). Based on statistical analysis, the frequency of the occurrence of insulin resistance in vitamin D deficiency obese children was higher than in obese children without vitamin D deficiency with OR = 4.261 (95% CI 1.744 – 10.411), p = 0.001. CONCLUSION: The risk of insulin resistance in obese children with vitamin D deficiency is 4.261 times higher than obese children without vitamin D deficiency.

Vitamin D Metabolism

Hyperparathyroidism is an endocrine disease characterized by excessive production of parathyroid hormone in the main cells of the parathyroid glands. Depending on the cause of this disease, there are primary, secondary (SHPT) and tertiary hyperparathyroidism. The most common causes of SHPT are vitamin D deficiency and chronic kidney disease (CKD). Vitamin D is converted to its active form by hydroxylation in the renal tubules. Developmental abnormalities and chronic kidney diseases lead to atrophy of the tubular epithelial cells that causes a violation of vitamin D metabolism and the development of SHPT, which in turn are accompanied by a violation of calcium-phosphorus metabolism and a syndrome of musculoskeletal disorders. This article presents an analysis of a clinical case of a patient diagnosed secondary hyperparathyroidism against the background of vitamin D deficiency combined with polycystic kidney disease. This clinical case reflects the complexity of the differential diagnosis of the disease and the tactics of patient's management.
