Codelivery of Doxycycline and Hydroxychloroquine to Treatment of Brucellosis: An Animal Study

Abstract

Evaluation of various biochemical and immunological parameters in infectious diseases is one of the best indicators for a diagnosis and treatment process. The main goal of this project is to determine the effect of hydroxychloroquine and doxycycline loading into solid-lipid-nanoparticles (DOX-HCQ-SLN) on the both acute and chronic phases of brucellosis. In addition, evaluate some biochemical factors, trace elements, and inflammatory elements. Blood serum levels of Zn, Fe, Na, and K and hepatic biochemical parameters (AST, ALT, ALP, and TBil) were remarkably different between infected and healthy rats. Vitamin D was decreased, and CRP was increased in chronic and acute brucellosis. Quantitative evaluation of these mentioned parameters can be useful to diagnose brucellosis in advance. Due to the good effect of the synchronized use of hydroxychloroquine and doxycycline in the form of nanoparticles, the manipulation of these nanoparticles can help for better treatment and also reduction in brucellosis reinfection.
