The exact etiology of GP is not known. However, some studies have found an association between vitamin D and Bone Mineral Status (BMD) status with GP in their study. Objectives: To assess the serum level of vitamin D, and BMD and to determine their association with growing pain in children. Methods: This cross-sectional analytical study was conducted in the Department of Paediatrics, Bangabandhu Sheikh Mujib Medical University (BSMMU). Sixty children between the age of 6 - 12 years were included in the study from March 2020 to August 2021. Children who fulfilled the Evans criteria of GP were enrolled as cases and thirty age and sex matched healthy children were recruited as the control in the study. Informed written consent was obtained from patients and parents. Serum 25-hydroxy-vitamin-D levels and BMD were performed among cases and controls and subsequently compared to see their association in growing pain. A preformed semi-structured questionnaire was completed for each participant which included socio-demographic, clinical and laboratory characteristics. Appropriate statistical tests were applied for data analysis and performed by SPSS version 22. A p-value less than 0.05 was considered as significant at a 95% confidence interval. Results: In this study, 96.7% of growing pain patients had hypovitaminosis D and among them,<span style="font-family: "> the majority (86.7%) was vitamin D deficient. There was a significant association between vitamin D with GP compared to healthy control. BMD was significantly lower in the lumbar vertebra (L1 -<span style="font-family: "> L4) and femoral neck region (both right and left) among GP children compared to the control group. Conclusion: From this study, it may be concluded that the majority of children with GP had hypovitaminosis D and low BMD status compared to the control. Vitamin D deficiency and low BMD status were significantly associated with children with growing pain. Institutional Review Board (I.R.B.) Clearance Certificate (NO. BSMMU/2020/4503 Date: 15/03/2020) was provided from the office of the Registrar, Bangabandhu Sheikh Mujib Medical University, Dhaka, Bangladesh.展开更多

Methods 102 postmenopausal women recruited from Ruijin Hospital were osteoporotic. We measured the lumbar vertebrae and femur of all patients with a modal dual-energy X-ray absorptionmetry, and also the serum osteocalcin by ELISA. The VDR gene was amplified using a polymerase chain reaction (PCR). The VDR genotypes were determined by the PCR-RFLP. Results bb, aa and TT genotype were found mainly in these osteoporosis patients, only one BB and two tt were found among these patients. No significant association was observed among three subgroups of bb, Bb and BB. Conclusion The rareness of B and t alleles suggested that it is unlikely that they are important factors for the heredity of osteoporosis in Chinese women. Thus VDR gene typing may be of little value in assessing the osteoporosis risk in Chinese population.展开更多

Methods: A cross-sectional study carried out in Morocco between May 2010 and June 2011, covering out patients with JIA. The characteristics of patients were collected. The nutritional status was assessed by a food questionnaire including data of food intake during 7 consecutive days using 24-hour dietary recall. Food intake was quantified using the software Bilnut (Bilnut version 2.01, 1991). Bone mineral density (BMD in g/cm2) was measured by DXA method (X-ray absorptiometry) on a Lunar Prodigy. Results: The study consisted of 33 patients with JIA (4 - 16 years old). The median age of patients was 10.4 ± 4.3 years. Median disease duration was 2 (1 - 4.5) years. The group of patients with low dietary intake of proteins was associated with low BMD (p = 0.03). Low BMD was related with low intake of magnesium (p = 0.007) and vitamin C (p = 0.04) in children aged between 4 and 9 years. Low intake of vitamin E and folate was associated with high BMD in the other range of children (p < 0.001). Conclusion: This study suggests that low intake of protein and of some micronutrients (magnesium, vitamin C, vitamin E and folate) influence bone mass in children with JIA. Prospective studies with a larger number of patients seem to be necessary in order to confirm our findings.展开更多
