          Abstract

          Introduction:

          Aminoglycoside-induced acute kidney injury (AKI) is a pathology closely linked to oxidative and inflammatory reactions. Taking into account the previous reported antioxidant and anti-inflammatory effects of D-005, a lipid extract obtained from Cuban palm Acrocomia crispa (Arecaceae) fruits, this work aimed to evaluate the effects of D-005 on kanamycin-induced AKI.

          Methods:

          Male Wistar rats were divided into 7 groups: negative control (vehicle, Tween 65/H2O) and six groups treated with kanamycin to induce AKI: positive control (vehicle), D-005 (25, 100, 200, and 400 mg/kg) and grape seed extract (GSE, 200 mg/kg). D-005, vehicle, and GSE oral treatments were administered once daily for seven days, 1 h before kanamycin (500 mg/kg, i.p.). Serum uric acid and urea concentrations, renal histopathology, and oxidative markers (malondialdehyde (MDA), sulfhydryl (SH) groups, and catalase (CAT) activity) were assessed.

          Results:

          D-005 significantly reduced uric acid and urea levels, starting from D-005 100 mg/kg. Histopathologically, D-005, at all the tested doses, protected renal parenchyma structures (glomeruli, proximal tubules, and interstitium). These findings were accompanied by a significant reduction of MDA and SH group concentrations as well as restoration of CAT activity. The highest percentages of inhibition were obtained with the dose of 400 mg/kg. GSE, the reference substance, also prevented kanamycin-induced biochemical and histopathological changes, as well as reduced MDA and SH groups and restored CAT activity.

          Conclusion:

          The administration of repeated oral doses of D-005 significantly protected against kanamycin-induced AKI, which could be associated with the antioxidant and anti-inflammatory effects of this extract.

          Resumo

          Introdução:

          Lesão renal aguda induzida por aminoglicosídeos é uma patologia intimamente ligada a reações oxidativas e inflamatórias. Considerando efeitos antioxidantes e anti-inflamatórios relatados anteriormente do D-005, um extrato lipídico de frutos da palmeira cubana Acrocomia crispa (Arecaceae), este trabalho avaliou efeitos do D-005 na LRA induzida por canamicina.

          Métodos:

          Dividiu-se ratos Wistar machos em 7 grupos: controle negativo (veículo, Tween 65/H2O) e seis grupos tratados com canamicina para induzir LRA: controle positivo (veículo), D-005 (25, 100, 200, 400 mg/kg) e extrato de semente de uva (ESU, 200 mg/kg). D-005, veículo, e tratamentos orais com ESU foram administrados uma vez por dia durante sete dias, 1 h antes da canamicina (500 mg/kg, i.p.). Avaliou-se concentrações séricas de ácido úrico e ureia, histopatologia renal e marcadores oxidativos (malondialdeído (MDA), grupos sulfidrila (SH), atividade de catalase (CAT)).

          Resultados:

          D-005 reduziu significativamente níveis de ácido úrico e ureia, partindo de D-005 100 mg/kg. Histopatologicamente, D-005, em todas as doses testadas, protegeu estruturas do parênquima renal (glomérulos, túbulos proximais e interstício). Estes achados foram acompanhados por uma redução significativa das concentrações de MDA e grupo SH, e pela restauração da atividade CAT. As maiores porcentagens de inibição foram obtidas com a dose de 400 mg/kg. ESU, a substância de referência, também evitou alterações bioquímicas e histopatológicas induzidas por canamicina, reduziu MDA e grupos SH e restaurou atividade CAT.

          Conclusão:

          A administração de doses orais repetidas de D-005 protegeu significativamente contra LRA induzida por canamicina, que pode estar associada aos efeitos antioxidantes e anti-inflamatórios deste extrato.

              Acute kidney disease and renal recovery: consensus report of the Acute Disease Quality Initiative (ADQI) 16 Workgroup

              Acute kidney injury (AKI) and chronic kidney disease are increasingly recognized as interconnected entities and the term acute kidney disease (AKD) has been proposed to define ongoing pathophysiologic processes following an episode of AKI. In this Consensus statement, the Acute Disease Quality Initiative 16 Workgroup propose definitions and staging criteria for AKD, and strategies for the management of affected patients. They also make recommendations for areas of future research with the aims of improving understanding of the underlying processes and improving outcomes.
