Çocukluk Çağı Membranöz Glomerülonefrit Tanılı Hastaların Klinik Değerlendirmesi

Abstract

Objective: Membranous nephropathy (MN) is a rare immune complex disease in pediatric population then adults. The prognosis of MN is variable, ranging from spontaneous complete remission to end-stage renal disease (ESRD). The lack of large multicenter studies precludes the possibility of examining in detail the treatment options and clinical outcomes in these patients. The present study aimed to expand the literature on the clinical findings, treatment, and prognosis of MN in pediatric patients. Material and Methods: This single-center retrospective study included 13 patients with a diagnosis of primary and secondary membranous nephropathy. Results: The mean age of the sample was 12.29±3.67 years. Complete remission occurred in 7 (53.8%) patients (of which 1 case was spontaneous remission), and partial remission occurred in 4 (30.8%) patients. In long-term follow-ups; one patient had chronic kidney disease (CKD) and one patient had end-stage renal disease (ESRD). At the last-follow up, proteinuria was noted in 6 (46.2%) patients and microscopic hematuria was noted in 4 (30.8%) and 9 patients were still using low-dose steroids. Conclusion: The current findings have not identified any significant risk factors associated with the prognosis of MN in pediatric patients, but are thought to contribute to the limited data on pediatric MN. Most of the available data on the natural history, treatment options, and long-term outcomes of MN in the pediatric population consists of small, uncontrolled case series. Therefore, we think that larger-scale clinical trials are necessary to clearly elucidate the factors related to the prognosis of pediatric MN.
