The pediatric rheumatic diseases are a heterogeneous group of rare diseases, posing a number of challenges for the use of traditional clinical and translational research approaches. Innovative comparative effectiveness approaches are needed to efficiently study treatment approaches and disease outcomes. The Childhood Arthritis and Rheumatology Research Alliance (CARRA) developed the consensus treatment plan (CTP) approach as a comparative effectiveness tool for research in pediatric rheumatology. CTPs are treatment strategies, developed by consensus methods among CARRA members, intended to reduce variation in treatment approaches, standardize outcome measurements, and allow for comparison of the effectiveness of different approaches with the goal of improving disease outcomes...

Lupus pneumonitis carries high mortality and is a rare manifestation of systemic lupus erythematosus (SLE). However, it is difficult to diagnose and is often mistaken as pneumonia, alveolar haemorrhage, or organizing pneumonia. Previous studies demonstrated that serum anti-Ro antibodies are elevated more frequently in SLE patients with pneumonitis than in those without. We report a 21-year-old female who was newly diagnosed as having SLE with nephritis and who suddenly developed right lung opacity and rapidly progressed to severe hypoxaemia despite the use of broad-spectrum antibiotics...

Systemic lupus erythematosus (SLE), an autoimmune disease of unknown etiology, is characterized by the production of autoantibodies and end-organ damage. Lupus nephritis affects up to 70% of patients with SLE and is the most critical predictor of morbidity and mortality. The immunopathogenesis of SLE is complex and most clinical trials of biologics targeting immune cells or their mediators have failed to show efficacy in SLE patients. It has therefore become increasingly clear that additional, local factors give rise to the inflammation and organ damage...

BACKGROUND: Raising evidence suggested a prognostic utility of tubulointerstitial lesions in lupus nephritis (LN). The exact prevalence of tubulointerstitial abnormalities and its predictive value among pediatric onset systemic lupus erythematous (pSLE) cases, however, remained unknown. METHODS: Sixty-seven pSLE subjects diagnosed with LN with initial renal samples available were enrolled and followed for an average of 6.49 ± 3.06 years. Renal histology was evaluated according to the International Society of Nephrology/Renal Pathology Society classification, National Institute of Health classification and tubulointerstitial activity index (TIAI)...

Diffuse alveolar hemorrhage (DAH) is a life-threatening complication of systemic lupus erythematosus (SLE). Although infrequent, its mortality is very high. While there are no established therapeutic guidelines, DAH has been traditionally managed with high-dose intravenous (IV) corticosteroids, cyclophosphamide, and plasma exchange. The efficacy of alternative therapies such as rituximab has been described only in a few cases. Herein, we report a 25-year-old Hispanic man who presented with acute-onset SLE manifested by polyarthralgia, nephritis, seizures, pancytopenia, severe hypocomplementemia, and elevated anti-dsDNA antibodies...

Glomerulonephritis is one of the most serious manifestations of systemic lupus erythematous (SLE). Because SLE is ≥10 times more common in women, a role for estrogens in disease pathogenesis has long been suspected. Estrogen receptor α (ERα) is highly expressed in renal tissue. We asked whether ERα expression contributes to the development of immune-mediated nephropathies like in lupus nephritis. We tested the overall effects of estrogen receptors on the immune response by immunization with OVA and induction of chronic graft-versus-host disease in female ERα-knockout mice...

Introduction: P-glycoprotein (P-gp) expression on activated lymphocytes in systemic lupus erythematosus (SLE) plays a role in active efflux of intracellular drugs, resulting in drug resistance. The role of P-gp-expressing lymphocytes in the pathogenesis of SLE remains unclear. The aim of this study was to determine the importance of P-gp+CD4+ cells in organ manifestations in refractory SLE. Methods: The proportion of P-gp+CD4+ cells was determined by flow cytometry in peripheral blood of patients with SLE (n=116) and healthy adults (n=10)...

REVIEW

The calcineurin inhibitors (CNIs) belong to a group of immunosuppressive agents that block T-cell activation through the suppression of the calcium/calcimodulin-dependent phosphatase calcineurin. Agents such as cyclosporine A (CSA) and tacrolimus (TAC) have long been used in patients with systemic lupus erythematosus (SLE). TAC is preferred to CSA in SLE because of the lower frequency of cosmetic, hypertensive and dyslipidemic adverse effects. Recent randomised controlled trials have demonstrated noninferiority of TAC to mycophenolate mofetil (MMF) or cyclophosphamide (CYC) for induction therapy of lupus nephritis...
