RESUMO
OBJECTIVES: To evaluate the benefits of the addition of leflunomide (LEF) in children with polyarticular course juvenile idiopathic arthritis (JIA), non-responsive to standard dose parenteral methotrexate (MTX). METHODS: In an observational study, 32 children with polyarticular course JIA failing standard dose MTX (up to 15 mg/m2/week sc for at least 3 and up to 6 months) received additional LEF. Permitted concomitant drugs included pulse steroids for flares and/or low bridging dose of prednisolone, intra-articular steroids and non-steroidal anti-inflammatory drugs. No other DMARDs had been used before enrolment. Patients underwent 8-12 weekly assessment. At each visit, core set of outcome variables and laboratory parameters, viz. haemogram and liver enzymes were recorded. The primary efficacy outcome was the ACR Pedi 30 criteria. At the last follow up, Wallace's criteria were used to determine children achieving remission. RESULTS: 25 of 32 children who followed up for at least 3 months were analysed. Mean follow up duration following addition of LEF was 1.61 years (range: 0.29 to 3.0 years). At 3 months, 68% of the patients met the ACR Pedi 30 response. 17 of the 20 children (85%) showed an ACR Pedi 30 response at 6 months and 16 out of 18 (88.8%) at 1 year. Of the 18 children followed up till the end of the study, 12 (66.6%) met the ACR Pedi 30 criteria and 9 (50%) were in clinical remission on medications (off steroids). Adverse effects were observed in 2 children (gastritis in one and elevated liver enzymes in the other). CONCLUSIONS: Our findings support further study of the role of this combination in the management of polyarticular course JIA refractory to standard dose MTX, especially in resource challenged settings where biologicals are unaffordable. The open observational nature of the study is its limitation.

Objectives: To study (1) epidemiological factors, clinical profile and outcomes of COVID-19 related multisystem inflammatory syndrome in children (MIS-C), (2) clinical profile across age groups, (3) medium-term outcomes and (4) parameters associated with disease severity. Design: Hospital-based prospective cohort study. Setting: Two tertiary care centres in Kerala, India. Participants: Diagnosed patients of MIS-C using the case definition of Centres for Disease Control and Prevention. Statistical analysis: Pearson χ2 test or Fisher's exact test was used to compare the categorical variables and independent sample t-test or Mann-Whitney test was used to compare the continuous variables between the subgroups categorised by the requirement of mechanical ventilation. Bonferroni's correction was used for multiple comparisons. Results: We report 41 patients with MIS-C, mean age was 6.2 (4.0) years, and 33 (80%) were previously healthy. Echocardiogram was abnormal in 23 (56%), and coronary abnormalities were noted in 15 (37%) patients. Immunomodulatory therapy was administered to 39 (95%), steroids and IVIg both were used in 35 (85%) and only steroids in 3 (7%) patients. Intensive care was required in 36 (88%), mechanical ventilation in 8 (20%), inotropic support in 21 (51%), and 2 (5%) patients died. Mechanical ventilation requirement in MIS-C was associated with hyperferritinaemia (p=0.001). Thirty-seven patients completed 3 months follow-up by April 2021, of whom 6 (16%) patients had some residual echocardiographic changes. Conclusions: Patients with MIS-C in our cohort had varied clinical manifestations ranging from fever with mild gastrointestinal and mucocutaneous involvement to fatal multiorgan dysfunction. Immediate and medium-term outcomes remain largely excellent except for the echocardiographic sequelae in a few patients which are also showing a resolving trend. Hyperferritinaemia was associated with the requirement of mechanical ventilation.

OBJECTIVES: To assess the course, outcome and complications in a mono-centric cohort of 53 patients with systemic onset juvenile idiopathic arthritis (s-JIA). METHODS: In an observational study, 53 consecutive patients diagnosed with s-JIA on or before October 2009 were enrolled and followed up between October 2009 and September 2012. At each 6-12 weekly visit, clinical examination, laboratory investigations and details of on-going treatment were recorded. Disease course was classified as monocyclic, intermittent and persistent. At last visit, outcome was studied with respect to remission (Wallace criteria) and Steinbrocker functional classification. Juvenile Arthritis Damage Index (JADI) was measured on a subset. RESULTS: In 53 patients analysed, the mean follow-up period was 5.5 ± 1.85 y, with a cumulative follow-up period of 291.5 patient-years. The mean age at diagnosis was 6.3 ± 3.4 y. Thirty-three patients suffered from disease and/or drug related complications. Infections were observed in 16 (30%) and macrophage activation syndrome in 5 (9.4%). Nine (17%) had a monocyclic course, 31 (58.5%) had an intermittent course and 13 (24.5%), a persistent course. At last visit, 9/9 patients of the monocyclic group, 17/31 in the intermittent group and 3/13 in the persistent group were in remission. At the end of the study, 96.2% of the index patients were Steinbrocker functional class I and II with the monocyclic group having the best functional outcome. JADI was performed on 20/53 patients. Nine had significant articular damage. The range of Juvenile arthritis damage index-articular (JADI-A) was 0-25/72 (median-6) and of Juvenile arthritis damage index-extra articular (JADI-EA) was 0-4/17 (median-1). CONCLUSIONS: The outcome of patients with s-JIA in a resource limited setting where early diagnosis, multidisciplinary care and availability of biologics are hurdles, is further altered by complications related to longstanding disease and over use of steroids.

A retrospective assessment of clinical characteristics, complications/ associations, laboratory investigations, treatment modalities and outcome in an inceptional cohort of 22 (male-13) children with juvenile dermatomyositis (JDM) receiving treatment at Jaslok Hospital, Mumbai during 1997- 2012 was performed . Mean age at diagnosis was 7.52 ± 3.99 years. Typical skin rash and muscle weakness were present in all children. Common complications included cutaneous ulcers (27.27%), dysphagia (22.72%) and calcinosis (18.18%).All patients presented with at least one of the serum muscle enzymes elevated. Absence of mortality and cardio-pulmonary complications and a monocyclic course in 72.7% of our patients are at variance from Western series.
