At present, there is no definite cure for the treatment of nephritis in modern medicine [8], and usually, immunosuppressive drugs such as corticosteroids [8, 25] and nonsteroidal anti-inflammatory [25], renin-angiotensin-aldosterone system (RAAS) blockade [41], antibiotics [40], diuretics [43], dialysis [38, 44], and kidney transplantation [45] are recommended. Here, REN is linked to nephritis.
