Abstract:

Systemic lupus erythematosus is a multisystem autoimmune disease. Apart from usual treatments, approximately 50% of lupus patients use complementary medicine. Resveratrol is a phytoalexin with various pharmacological properties. We hypothesised that prophylactic treatment with resveratrol may abrogate manifestations in pristane-induced murine model of lupus-like disease and piperine; a bio-enhancer of resveratrol may enhance these properties. The prophylactic effect of resveratrol (25 mg/kg body weight: P-Res) alone and in combination with piperine (2.5 mg/kg body weight: P-RP) were assessed. P-Res and P-RP were equally efficient in mitigating oxidative stress (enzyme activity of catalase, superoxide dismutase, glutathione peroxidase and level of reduced glutathione, lipid peroxidation, and reactive oxygen species). Inflammation is associated with an increase in inflammatory cytokines. IL-6 was decreased by 71.60% with P-Res, and TNF-α was reduced by 59.70% with P-Res and 62.66% with P-RP (p < 0.05). Prevention of renal pathologies was evident by reduction in creatinine level by P-RP (p < 0.05) and abrogation of proteinuria (P-Res and P-RP). P-RP was efficient in restoring histopathology of liver and lungs and decreased immune complexes in lungs. P-Res proved more beneficial by extenuating lipogranulomas, histopathological manifestations in kidney, liver, and lungs, and eliminating immune complexes in liver and lungs. None of the treatments could regulate auto-antibody formation. Resveratrol decreases the susceptibility of developing pathogenesis in murine model of lupus-like disease. The results also conclude that addressing the bioavailability of resveratrol using it in combination with piperine does not prove more efficacious in preventing lupus-associated pathologies than resveratrol alone.
