Determation of HLA DRB1, DPB1, DQA1, DQB1 and B27, may be helpful to diagnose JIA cases where diagnostic dilemma is present. The aim of the study was to find out the association of HLA alleles with JIA and its subtypes. Methods: This cross sectional study was conducted in the department of Pediatrics, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, from April 2020 to March 2021. A total of 50 cases and 25 controls attending pediatric rheumatology clinic and pediatric OPD were enrolled in the study. Data were collected by a pre-designed questionnaire containing socio-demographic, clinical and laboratory parameters. HLA DR-B1, DQ-A1, DQ-B1 and B27 typing were done for the cases and controls from blood samples by polymerase chain reaction sequence specific primer (PCR-SSP) method. Data were analyzed by SPSS version 26. Frequency, percentage, chi square test and Fisher exact tests were done for statistical analysis. Results: HLA DR-B1_10 had significant positive association whereas HLA DR-B1_03 and B1_16 had negative association with overall JIA cases. Poly-articular JIA, oligo-articular JIA and ERA had association with HLA DRB1_01, B1_08 and B1_12 respectively. HLA DQA1-01 and A1_02 had positive association. However, DQ-A1_06 was negatively associated with JIA cases. Oligo JIA was positively associated with HLA DQ-A1_01, whereas poly JIA and ERA had association with A1_02. Though, HLA DQ_B1 had no association with overall JIA cases, analysis showed association of poly JIA with DQ-B1_04. Frequency of HLA DQ-B1_02 and 03 were higher among ERA cases, though not significant, but they had strong association with HLA B27. Conclusion: HLA associations were present with overall JIA and each sub-groups had different patterns of HLA associations including some protective roles.展开更多

Several patients develop side effects, which may lead to low quality of life and non-compliance to MTX. To reduce MTX-induced side effects, folic acid supplementation is prescribed by most rheumatologists. Even after that, some patients have symptoms while receiving MTX. Objectives: To assess the efficacy of folinic acid in comparison to folic acid for reducing the side effects of MTX in JIA patients. Material and methods: In this prospective observational study, newly diagnosed cases of JIA who would be getting MTX were included by purposive sampling. Data were collected using a predesigned questionnaire. Among 40 patients, 20 received folinic acid (Group A), and 20 received folic acid (Group B). Disease activity levels were assessed by JADAS-27 (Juvenile Arthritis Disease Activity Score). Contents from the MISS (MTX Intolerance severity score) questionnaire were used to assess the side effects. All patients were evaluated at baseline, 6th, and 12th weeks. Results: There were significant differences in the frequency of MTX-related adverse events between folinic acid (Group A) and folic acid (Group B). Group A patients only had nausea (10% and 15% in the 6th & 12th week respectively) and vomiting (5% at both follow-ups). On the other hand, in addition to nausea (70% and 95% in the 6th & 12th week) and vomiting (20% and 90% in the 6th & 12th week), folic acid group patients had restlessness, crying, and irritability. Self-discontinuation of MTX was present in the folic acid group (5% & 10% in the 6th & 12th week). Improvement of disease activity was more in the folinic acid group. Conclusion: The folinic acid group had significantly fewer side effects. Improvement of disease activity was more and compliance was also better among them.

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.
