ABSTRACT
BACKGROUND: Biological disease-modifying antirheumatic drugs (bDMARDs) are treatment options for refractory juvenile idiopathic arthritis (JIA) cases which cannot be afforded by the majority. Tofacitinib is a novel Janus kinase inhibitor, which is reported to be a cost-effective oral alternative to biologics. This prospective observational study was carried out to observe the efficacy and safety of tofacitinib in refractory polyarticular course JIA patients. MATERIALS AND METHODS: The study was conducted in the Department of Pediatrics, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka. Twenty-seven refractory polyarticular course JIA patients were included in this study. Patients received tofacitinib at recommended doses. Disease activity level was assessed by Juvenile Arthritis Disease Activity Score (JADAS) 27. Cases were evaluated at baseline and at the 6th, 12th and 24th weeks. Safety was monitored from history, examination findings and laboratory reports. Data were analyzed using appropriate statistical tests. RESULTS: Enthesitis-related arthritis was the commonest type (37%) followed by polyarticular (rheumatoid factor+) and systemic JIA. There was significant improvement in JADAS 27 in all the subtypes of JIA except oligoarticular extended type. Among 100% high disease activity state cases at baseline, 70.4% were inactive at 24 weeks. It was also possible to significantly reduce the dose of steroid. Few side effects like headache and vomiting, elevation of alanine aminotransferase and anemia were observed at 6 weeks. These side effects subsequently improved. CONCLUSION: Significant reduction of disease activity score was observed from baseline to follow up in this study. Tofacitinib was well tolerated with minimum side effects.

BACKGROUND: Systemic lupus erythematosus (SLE) is a multisystem, chronic but often episodic, autoimmune disease that is characterized by the presence of antinuclear antibodies (ANA). The criteria set by American College of Rheumatology are widely used for diagnosis of SLE. Elevation of ANA titer is the most sensitive of the ACR criteria. There are different methods for detection of ANA. Indirect immunofluorescence (ANA-IFA) and enzyme immunoassay (ANA-EIA) are commonly used methods. The sensitivity of ANA-IFA using HEp-2 cell substrate is 90-100% in systemic rheumatic diseases. In Bangladesh most of the laboratories use ANA-EIA for detection of ANA. As the sensitivity of ANA-EIA is lower than ANA-IFA it might be that we are missing many cases of ANA positivity in childhood SLE cases. OBJECTIVES: To detect ANA by immunofluorescence assay using HEp-2 cell substrate and enzyme immunoassay in childhood SLE and to compare the diagnostic performance of these methods. MATERIAL AND METHODS: This is a cross-sectional analytical study. A total of 40 patients were enrolled. Among them 20 were childhood SLE cases. Another 20 patients of childhood rheumatic diseases other than SLE were taken as the disease control group. RESULT: In childhood SLE cases, 100% were ANA-positive by IFA and 55% were ANA positive by EIA. The sensitivity of ANA-IFA was 100%. In contrast, sensitivity of ANA-EIA was 55%. CONCLUSION: ANA-IFA is superior to ANA-EIA for detection of ANA in childhood SLE patients. ANA-IFA should be the primary screening test for children with clinical features suggestive of SLE.

The purpose of this study was to develop appropriate formative assessment strategies as a means of promoting relevant learning outcomes in paediatrics. Fifty fifth-year medical students were exposed to two formative assessment strategies, 'self-assessment exercises' and 'the Objective Structured Clinical Examination'. At the end of exposure, students' perceptions of the formative assessment were sought using a Likert-type five-point scale. From the results of the study conclusions were drawn that strong formative assessment strategies can be implemented by introducing OSCE and self-assessment exercises, which can promote relevant learning outcomes in paediatrics and thereby prepare medical students to become competent in managing paediatric patients, even in the absence of effective summative assessment.
