Abstract

Context: Acute kidney injury (AKI) is a common complication of renal pathology and an adverse drug effect. Mortality caused by AKI reaches 80% in some groups of patients. Therefore, the search of the effective agents for AKI treatment is an important task of the pharmaceutical science.

Aims: To evaluate the efficacy of various combinations of N-acetylglucosamine (NAG) and quercetin in rats with AKI.

Methods: The study was conducted on the model of acute glycerol nephrosis in rats. Combinations of NAG and quercetin in ratios of 1:2, 1:1, 2:1 and 3:1 were studied at a dose of 50 mg/kg with daily intramuscular injection for a week. The efficacy of the combinations was assessed by the indicators of animal survival, excretory renal function, nitrogen metabolism and nephroprotective activity (NA).

Results: The combination of NAG and quercetin in the 1:1 ratio was the most effective. There was a significant increase of excretory renal function and normalization of nitrogen metabolism under the influence of this combination. This determined the NA level up to 69.7%, which was the highest value in the presented study. This combination was statistically superior to all others, as well as to quercetin, by the efficacy level. In addition, the combination exceeded the quercetin in NA index by 2.7 times.

Conclusions: Thus, the NAG/quercetin combination in 1:1 ratio in injectable dosage form is the most promising for kidney diseases treatment.

Keywords: N-acetylglucosamine; acute kidney injury; nephroprotective effect; quercetin.

Resumen

Contexto: La insuficiencia renal aguda (IRA) es una complicación frecuente de la patología renal y un efecto adverso de los medicamentos. La mortalidad por IRA alcanza el 80% en algunos grupos de pacientes. Por lo tanto, la búsqueda de agentes efectivos para el tratamiento de IRA es una tarea importante de las ciencias farmacéuticas.

Objetivos: Evaluar la eficacia de varias combinaciones de N-acetilglucosamina (NAG) y quercetina en ratas con IRA.

Métodos: El estudio se realizó sobre el modelo de nefrosis aguda inducida por glicerol en ratas. Las combinaciones de NAG y quercetina en proporciones de 1:2, 1:1, 2:1 y 3:1 se estudiaron a una dosis de 50 mg/kg con administración intramuscular diaria durante una semana. La eficacia de las combinaciones se evaluó mediante los indicadores de supervivencia animal, función renal excretora, metabolismo del nitrógeno y actividad nefroprotectora (AN).

Resultados: La combinación de NAG y quercetina en la proporción de 1:1 fue la más efectiva. Hubo un aumento significativo de función renal excretora y normalización de metabolismo del nitrógeno bajo la influencia de esta combinación. Esto determinó el nivel de AN hasta el 69.7%, que fue el valor más alto en el estudio presentado. Esta combinación fue estadísticamente superior a todas las demás, así como a la quercetina, por el nivel de eficacia. Además, la AN de la combinación superó la quercetina en 2,7 veces.

Conclusiones: Por lo tanto, la combinación de NAG/quercetina en la proporción de 1:1 en forma de dosis inyectable es la más prometedora para el tratamiento de enfermedades renales.

Palabras Clave: N-acetilglucosamina; efecto nefroprotector; insuficiencia renal aguda; quercetina.
