Objective To formulate consensus treatment plans (CTPs) for induction therapy of newly-diagnosed proliferative lupus nephritis (LN) in juvenile systemic lupus erythematosus (jSLE). Methods A structured consensus formation process was employed by the members of the Childhood Arthritis and Rheumatology Research Alliance (CARRA) after considering the existing medical evidence and current treatment approaches. Results After an initial Delphi survey (response rate 70%), a 2-day consensus conference, and two follow-up Delphi surveys (response rates 63–79%), consensus was achieved for a limited set of CTPs addressing the induction therapy of proliferative LN. These CTPs were developed for prototypic patients defined by eligibility characteristics, and included immunosuppressive therapy with either mycophenolic acid orally twice per day, or intravenous cyclophosphamide once per month at standardized doses for six months. Additionally, the CTPs describe three options for standardized use of glucocorticoids; including a primarily oral, a mixed oral/intravenous, and a primarily intravenous regimen. There was consensus on measures of effectiveness and safety of the CTPs. The CTPs were well accepted by the pediatric rheumatology providers treating children with LN, and up to 300 children per year in North America are expected to be candidates for the treatment with the CTPs. Conclusion CTPs for induction therapy of proliferative LN in jSLE based on the available scientific evidence and pediatric rheumatology group experience have been developed. Consistent use of the CTPs may improve the prognosis of proliferative LN, and support the conduct of comparative effectiveness studies aimed at optimizing therapeutic strategies for proliferative LN in jSLE.
Treatment with anakinra was associated with short-term improvements in large joint counts and laboratory parameters of active disease. Higher anakinra doses may be more efficacious in treating the systemic inflammatory response in systemic onset juvenile idiopathic arthritis patients. A subset of patients had periods of arthritis during treatment, and local side-effects were frequent. Our experience supports the continued use of interleukin-1 inhibition in systemic juvenile arthritis and the search for more effective and more tolerable forms of interleukin-1 inhibition.
Objective. Few data are available regarding the rates of serious adverse events (SAEs) and important medical events (IMEs) outside of product-based registries and clinical trials for juvenile idiopathic arthritis (JIA). The Enhanced Drug Safety Surveillance Project (EDSSP) was developed to pilot a novel system to collect SAEs/IMEs in children with JIA. This analysis reports the results from this 4-year (2008 -2012) EDSSP. Methods. Participating physicians were surveyed monthly to ascertain whether their JIA patients experienced an SAE or IME. Sites were surveyed every 6 months to determine the number of unique JIA patients seen at each site during that 6-month period. Reporting rates were calculated per 100 person-years and 95% confidence intervals (95% CIs) were calculated based on a Poisson distribution. Results. Thirty-seven Childhood Arthritis and Rheumatology Research Alliance sites with 115 physicians participated. The mean response rate to the monthly surveys was 65%. There were 147 total SAEs and 145 total IMEs. The largest proportion of SAEs and IMEs occurred in children with polyarticular JIA (39% and 37%, respectively). The majority of SAEs and IMEs were reported for patients receiving therapy with biologic agents (76% and 69%, respectively). The total event rate for SAEs and IMEs combined was 1.07 events per 100 person-years (95% CI 0.95-1.19). The rates for SAEs and IMEs were 0.54 per 100 person-years (95% CI 0.45-0.63) and 0.53 per 100 person-years (95% CI 0.49 -0.62), respectively. Conclusion. The EDSSP provided a simple tool for SAE/IME reporting within an established research network and resulted in a similar range of reported events as captured by a traditional product-based registry.
Severe microscopic polyangiitis can result in acute respiratory failure and renal failure and is commonly treated with mechanical cardiopulmonary support, along with immunosuppression. We report the use of continuous renal replacement therapy and rituximab in a 13-year-old boy with P-antineutrophil cytoplasmic antibody-positive microscopic polyangiitis, resulting in pulmonary hemorrhage and acute renal failure. The patient was treated with high-frequency oscillatory ventilation, extracorporeal membrane oxygenation, and continuous renal replacement therapy, in addition to plasmapheresis, corticosteroids, cyclophosphamide, and rituximab.
