Update on the Treatment of Glomerulonephritis in Adults in Low-to-Middle-Income Countries

Glomerular diseases are a common cause of chronic kidney disease in several low-to-middle-income countries (LMIC). Additionally, they represent up to 52% of patients with end-stage renal disease (ESRD) in Africa. Current guideline recommendations for the treatment of glomerular diseases may not always be applicable in LMIC due to various challenges related to disease diagnosis and the availability of medicines. A treatment approach that starts with disease diagnosis and proper use of adjuvant therapies mainly targeted at blood pressure and proteinuria reduction is an effective therapeutic option and is recommended for patients in LMIC with glomerular pathologies. The use of immunosuppressive therapies in adults with glomerular diseases should, as far as is possible, be guided by the histological diagnosis obtained through renal biopsy. Prednisone and cyclophosphamide still form the bulk of treatment for glomerular diseases in most countries. Due to the adverse effects associated with immunosuppression, prednisone and cyclophosphamide use must be carefully weighed against the risk of potential side effects, and there is a need for frequent monitoring to assess treatment efficacy, patient response, and adverse effects. It is not advisable to use immunosuppressive drugs (e.g., cyclosporine) that require monitoring of plasma levels in centres where such facilities are not available, given the possible associated nephrotoxicity. The purpose of this narrative review is to provide an update on the treatment of common glomerular diseases and to highlight simple approaches to treatment in LMIC. Knowledge of guideline recommendations on the treatment of various glomerular diseases will provide important understanding on useful therapeutic approaches.
