Medicine (Baltimore) 2024; 103:e39059. [PMID: 39058868 PMCID: PMC11272325 DOI: 10.1097/md.0000000000039059] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/14/2024] [Accepted: 07/02/2024] [Indexed: 07/28/2024] Open
Abstract
OBJECTIVE The objective of this meta-analysis was to compare the efficacy and safety between glucocorticoids combined with mycophenolate mofetil (MMF) versus glucocorticoids combined with cyclophosphamide (CTX) for henoch schonlein purpura nephritis (HSPN) in children. METHODS Databases including PubMed, EMbase, the Cochrane Library, China National Knowledge Infrastructure, and Wanfang database were searched from the inception to April 5th, 2024. Eligible studies comparing glucocorticoids combined with MMF versus glucocorticoids combined with CTX for HSPN in children were included. Data were analyzed using Review Manager Version 5.3. RESULTS Ten studies were included in the meta-analysis. Six randomized controlled trials (RCTs) and 4 non-randomized studies involving 675 patients were identified. Compared with CTX therapeutic schedule, MMF therapeutic schedule had a higher complete remission (CR) within the 6 months (OR 1.61, 95%CI 1.16-2.22, P = .004) and CR within the 12 months (OR 1.73, 95%CI 1.00-2.97, P = .05). However, there was no significant difference between MMF and CTX therapeutic schedule concerning total remission (TR) within the 6 months (OR 1.54, 95%CI 0.82-2.92, P = .18) and TR within the 12 months (OR 2.08, 95%CI 0.86-5.01, P = .10). In addition, incidences of gastrointestinal discomfort (OR 0.33, 95%CI 0.19-0.56, P < .0001), liver function injury (OR 0.28, 95%CI 0.09-0.87, P = .03), myelosuppression (OR 0.15, 95%CI 0.06-0.41, P = .0001), alopecia (OR 0.25, 95%CI 0.07-0.91, P = .03) in MMF therapeutic schedule were all lower than CTX therapeutic schedule. There was no statistically significant difference between the 2 therapeutic schedules concerning infection (OR 0.90, 95%CI 0.50-1.61, P = .72), rash (OR 0.38, 95%CI 0.07-2.04, P = .26). CONCLUSION Glucocorticoids combined with MMF had a higher CR and lower incidence of adverse effects compared with glucocorticoids combined with CTX in the treatment of HSPN in children.

Clin Kidney J 2024; 17:sfae115. [PMID: 38742208 PMCID: PMC11089412 DOI: 10.1093/ckj/sfae115] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/24/2024] [Indexed: 05/16/2024] Open
Abstract
Background This study aimed to observe the efficacy and safety of tacrolimus in the treatment of refractory immunoglobulin A vasculitis nephritis (IgAVN). Methods Sixteen patients with IgAVN who had been previously treated with cyclophosphamide shock therapy at least five times, some of whom had also received mycophenolate but still had persistent proteinuria, were enrolled. The clinical and pathological data were collected and analysed. Results The average (mean ± standard deviation) age at the initial assessment for the group of 16 patients was 10 ± 2.7 years. Finally, at the end of their respective follow-up time point, 6 of the 16 patients achieved complete remission (37.5%), 5 achieved partial remission (31.2%), and 5 had no remission (31.2%). A significant difference was found in the median proteinuria before and after a 6-month course of tacrolimus treatment [19.2 (11.2, 31.9) vs 7.8 (4.3, 13.9) mg/kg/day] (P < .05). During the first 6 months of tacrolimus treatment, all patients' estimated glomerular filtration rate levels remained normal. The mean tacrolimus blood concentration was 6.0 ± 2.6 ng/mL. The median prednisone dosage was decreased from 10 mg/day to 5 mg/day, and prednisone was eventually stopped in three individuals. No drug-related adverse effects were observed during treatment. Conclusions Tacrolimus has demonstrated efficacy in increasing remission rates, significantly lowering urinary protein levels, and reducing steroid use in children with refractory IgAVN. Further research is required to investigate its optimal blood concentrations, long-term effects and renoprotective properties.

Dixon A, Blanchette E, Kendrick J. A lack of KDIGO guidelines for adolescents and young adults with IgA nephropathy. Pediatr Nephrol 2024; 39:297-304. [PMID: 37261517 DOI: 10.1007/s00467-023-06027-4] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/27/2023] [Revised: 04/27/2023] [Accepted: 05/09/2023] [Indexed: 06/02/2023]
Abstract
BACKGROUND IgA nephropathy (IgAN) is one of the most prevalent primary glomerular diseases in children and adolescents. In 2021, The Kidney Disease: Improving Global Outcomes (KDIGO) released Clinical Practice Guidelines for the Management of Glomerular Diseases as an update to the 2012 guidelines. However, the lack of available evidence for the treatment of IgAN in children has led to an absence of treatment recommendations. CLINICAL CASE We present the case of a 19-year-old male with IgAN who was lost to follow-up after an appointment at a children's hospital 3 years prior. He presents for care at an adult hospital after running out of his medications for many months. He is found to have an elevated blood pressure of 152/97 and an elevated creatinine at 0.8 mg/dL. DISCUSSION There is not only a need for treatment guidelines for IgAN in pediatric patients, but also a need for guidelines for adolescent patients with IgAN as they transition from pediatric to adult care. Therefore, we review the KDIGO treatment guidelines for adults with IgAN and the treatment evidence for children with IgAN and discuss the management dilemma that exists for adolescents and young adults (AYA) with IgAN. Specifically, we propose renin-angiotensin-aldosterone blockade (RASB) treatment, irrespective of blood pressure, for AYA with proteinuria >0.5 g/day. We also propose treatment with corticosteroids for patients with proteinuria >1 g/day and/or mesangial hypercellularity. CONCLUSION The formation of treatment guidelines for patients transitioning from pediatric to adult nephrology care is paramount.

Abstract
Immunoglobulin A vasculitis (IgAV) nephritis, also known as Henoch-Schönlein purpura nephritis (HSPN), is a condition in which small blood vessel inflammation and perivascular IgA deposition in the kidney caused by neutrophil activation, which more often leads to chronic kidney disease and accounts for 1%–2% of children with end-stage renal disease (ESRD). The treatment principles recommended by the current management guidelines include general drug treatment, support measures and prevention of sequelae, among which the therapeutic drugs include corticosteroids, immunosuppressive agents and angiotensin system inhibitors. However, the concentration range of immunosuppressive therapy is narrow and the individualized difference is large, and the use of corticosteroids does not seem to improve the persistent nephropathy and prognosis of children with IgAV. Therefore, individualized maintenance treatment of the disease and stable renal prognosis are still difficult problems. Genetic information helps to predict drug response in advance. It has been proved that most gene polymorphisms of cytochrome oxidase P450 and drug transporter can affect drug efficacy and adverse reactions (ADR). Drug therapy based on genetics and pharmacogenomics is beneficial to providing safer and more effective treatment for children. Based on the pathogenesis of IgAV, this paper summarizes the current therapeutic drugs, explores potential therapeutic drugs, and focuses on the therapeutic significance of corticosteroids and immunosuppressants in children with IgAV nephritis at the level of pharmacogenomics. In addition, the individualized application of corticosteroids and immunosuppressants in children with different genotypes was analyzed, in order to provide a more comprehensive reference for the individualized treatment of IgAV nephritis in children.
