OBJECTIVE To describe the clinical, laboratory, and histopathologic features, current treatment, and outcome of patients with macrophage activation syndrome (MAS) complicating systemic juvenile idiopathic arthritis (JIA). METHODS In this multinational, multicenter study, pediatric rheumatologists and hemato-oncologists entered patient data collected(More)
IgG4 related systemic disease (IgG4-RSD) has been recognised in the last few years. Orbital pseudotumor as a presentation of IgG4-RSD is one of the rare complaints encountered in pediatric population. It is an inflammatory condition of unknown etiology characterized by tumorous swelling of the organs, characteristic histopathologic changes and elevated(More)
Methotrexate (MTX) was originally synthesised as an anti-cancer drug. Soon it was also used in immunoinflammatory diseases, mainly in the field of rheumatology. However, the dose used in oncology is several-fold higher as compared to the dose used in systemic immunoinflammatory rheumatological diseases. This led to the use of terms 'low-dose MTX' (LD-MTX)(More)
Heme oxygenase-1 (HO-1) is a stress-induced enzyme that catalyses the oxidation of heme to biliverdin. The primary deficiency of this enzyme has been shown in HO-1 knockout mice, and is characterized by intrauterine death and chronic inflammation. The first case of human HO-1 deficiency was reported in 1999. Human HO-1 deficiency has been observed to(More)
This chapter aims to give a global perspective to paediatric rheumatology. The main points covered are the incidence, recognition of paediatric autoimmune diseases, and ethnic/geographic distribution. The most prevalent disease is juvenile idiopathic arthritis; robust data are still required for childhood-onset systemic lupus erythematosus, dermatomyositis,(More)
Rheumatology is a relatively new specialty in the field of Pediatrics in India where there are only a few centres of excellence. Awareness about these conditions in childhood is lacking and patients are often referred late resulting in poor long term outcomes. This article highlights the needs of the paediatric rheumatology patients which are complex and(More)
Though rare, childhood lupus is a disease with the potential to have serious short and long term effects in children. These effects are to do with the disease itself, organ damage consequent to ongoing inflammation and/or because of side effects of medications. As children have an early disease onset, accrual organ damage over the years and growth and(More)
Juvenile idiopathic arthritis (JIA) is a relatively uncommon disorder in childhood. Expertise however should be the corner stone of care of children with JIA, as early appropriate treatment is mandatory to ensure best possible short and long-term outcome for children with JIA. Therefore comprehensive treatment centers (with multi disciplinary teams) should(More)
Children with rheumatologic disorders need periodic systematic evaluation of their disease status so that all aspects of the child's life that are affected can be adequately assessed. The commonest rheumatologic disease that afflicts children is Juvenile Idiopathic Arthritis (JIA). The child with JIA should have several domains assessed at regular(More)
