Intracellular ROS generated in chikungunya patients with persisting polyarthralgia can be reduced by Tinospora cordifolia leaf extract. - GreenMedInfo Summary

Chikungunya (CHIK) is an arboviral infection having huge global burden affecting the life style of the patient badly due to debilitating polyarthralgia. This study aims to evaluate intracellular reactive oxygen species (ROS) in peripheral blood of patients suffering with persisting polyarthralgia post CHIK infection and the potential ofleaf extract in scavenging those free radicals in peripheral blood mononuclear cells (PBMC) of the patient. Peripheral blood was collected from written informed consented patients and intracellular ROS was measured in PBMC of patients suffering with persisting polyarthralgia 3 months post CHIK infection followed by the study of free radical scavenging byleaf extract in those cells through flow cytometry. Control population comprising healthy donors were also included in the study. As compared to healthy subjects, twofold higher Intracellular ROS (17.89 ± 1.007 vs. 37.96 ± 1.510,< 0.0001) was found in patient PBMC. Ex-vivo treatment of those PBMC with ethanolic extract ofleaf (1 μg/mL) decreased intracellular ROS significantly by twofold (< 0.0001). This study reports that CHIK infection produces high level of intracellular ROS in the patients suffering with persisting polyarthralgia, which was significantly scavenged by ex vivo treatment with leaf extract.
