Protective Effects of Gymnema inodorum Leaf Extract on Plasmodium berghei-Induced Hypoglycemia, Dyslipidemia, Liver Damage, and Acute Kidney Injury in Experimental Mice

Abstract

Malaria complications are the most frequent cause of mortality from parasite infection. This study is aimed at investigating the protective effect of Gymnema inodorum leaf extract (GIE) on hypoglycemia, dyslipidemia, liver damage, and acute kidney injury induced by Plasmodium berghei infection in mice. Groups of ICR mice were inoculated with $1\times {10}^7$ parasitized erythrocytes of P. berghei ANKA and administered orally by gavage with 100, 250, and 500 mg/kg of GIE for 4 consecutive days. Healthy and untreated controls were given distilled water, while the positive control was treated with 10 mg/kg of chloroquine. The results showed that malaria-associated hypoglycemia, dyslipidemia, liver damage, and acute kidney injury were found in the untreated mice as indicated by the significant alteration of biological markers. On the contrary, in 250 and 500 mg/kg of GIE-treated mice, the biological markers were normal compared to healthy controls. The highest protective effect was found at 500 mg/kg similar to the CQ-treated group. However, GIE at a dose of 100 mg/kg did not show protection during malaria infection. This study demonstrated that GIE presented potential therapeutic effects on PbANKA-induced hypoglycemia, dyslipidemia, liver damage, and acute kidney injury. The results obtained confirm the prospect of G. inodorum as an essential source of new antimalarial compounds and justify folkloric use as an alternative malarial treatment.
