The article discusses the study on the clinical indications, efficacy, and adverse events (AEs) for B-cell depleting agent and rituximab in children with systemic lupus erythematous (SLE). It states that rituximab improves the disease activity of children with lupus and serious infrequent AEs. The study suggest further studies.

The aim of this study was to determine whether CNIs can be safely withdrawn in paediatric patients with declining renal allograft function receiving MMF and corticosteroids for long-term immunosuppression following renal transplantation. We performed a retrospective review of paediatric renal transplant recipients who received MMF with corticosteroids at least three months after transplantation with or without CNI in a single centre. Thirty-eight children (71% male), mean age 7.2 ± 3.7 yr received MMF and corticosteroids, with 29 (76%) receiving a CNI. Mean follow-up was 59.2 ± 42 months post-MMF commencement and 109 ± 98.8 months post-transplantation. Patient and renal allograft survival were 100% and 94%, respectively. There was a significant improvement in eGFR after MMF introduction both in children on a CNI and those where the CNI was withdrawn, with stabilisation of eGFR after two yr. There was no significant difference in the number of acute rejection episodes prior to or following introduction of MMF between the groups. MMF in combination with corticosteroids is a safe and effective immunosuppressive regimen in paediatric renal transplantation. Complete withdrawal of CNIs after conversion to MMF should be considered in all patients, to preserve renal function as evidenced by improved eGFR. [ABSTRACT FROM AUTHOR]

Objective: B cell dysregulation is involved in the development of childhood-onset systemic lupus erythematosus (SLE). The safety and efficacy of B cell depletion therapy is evaluated in the the largest series of children to be presented in the literature. Methods: 19 children (89% female) with SLE, aged 6-16 (median 14) years, treated with rituximab in a single centre were retrospectively reviewed. The British Isles Lupus Assessment Group (BILAG) index and biochemical, haematological and immunological parameters were evaluated before and after treatment, with the primary outcome assessed as normal results. Rituximab therapy was used for acute life- or organ-threatening symptoms or symptoms that had not responded to standard treatment. The range of symptoms included lupus nephritis, cerebral lupus and severe general symptoms. Aituximab 750 mg/m² was given intravenously twice, usually within a 2-week period. Patients were followed up for 6-38 (median 20) months. Results: Rapid reduction of SLE disease activity was observed within the first month, represented by a reduction of BILAG scores (14 to 6, p<0.005) and an improvement in renal function (estimated glomerular filtration rate of 54 to 68 ml/min/1.73 m², p = 0.07), immunological (complement C3: 0.46 to 0.83 g/l, p = 0.02) and haematological (haemoglobin: 9.7 to 10.3 g/dl, p = 0.04) parameters. No serious side effects were observed, except for herpes zoster in five cases. Conclusion: In our cohort of children, rituximab was safe and effective when used in combination with standard immunosuppressive agents. Randomised controlled studies are needed to further evaluate the safety and efficacy of rituximab therapy. [ABSTRACT FROM AUTHOR]
