The present study investigated the effect of diminazene, lisinopril, or valsartan on adenine-induced chronic kidney disease (CKD) in rats. The animals were divided into five groups (n = 6). The first and second groups received normal diet and adenine in the feed at a dose of 0.25% w/w for 35 days, respectively. The third, fourth, and fifth groups were treated as the second group but also received diminazene (15 mg/kg/day), lisinopril (10 mg/kg/day), and valsartan (30 mg/kg/day), respectively, for 35 days. Adenine significantly increased plasma urea, creatinine, neutrophil gelatinase-associated lipocalin (NGAL), calcium, phosphorus, and uric acid. In addition, adenine increased urinary albumin/creatinine ratio and N-Acetyl-β-D-glucosaminidase (NAG)/creatinine ratio and reduced creatinine clearance. Adenine also significantly increased the plasma concentrations of inflammatory cytokines (plasma tumor necrosis factor–alpha [TNF-α] and interleukin-1beta [IL-1β]) and significantly reduced antioxidant indices (catalase, glutathione reductase [GR], and superoxide dismutase [SOD]). Histopathologically, renal tissue from adenine-treated rats showed necrosis of renal tubules, tubular casts, shrunken glomeruli, and increased renal fibrosis. All drugs ameliorated adenine-induced biochemical and histopathological changes. The protective effect of the three drugs used is, at least partially, due to their anti-inflammatory and antioxidant effects. Our results show that administration of diminazene, lisinopril, or valsartan had a comparable effect on the reversal of the biochemical and histopathological indices of adenine-induced CKD in rats.
