IgG and IgG subclass antibodies in patients with active cutaneous leishmaniasis

Abstract

This research was planned to detect IgG and IgG subclasses in sera of patients with active cutaneous leishmaniasis (CL). Sera from 30 patients with active CL aged between 10 and 50 years and from 30 healthy controls aged between 8 and 50 years were included in the study. Levels of IgG and its subclasses were measured by a nephelometer. Levels of IgG, IgG1 and IgG3 in the CL patients were higher than in the controls. In addition, IgG and IgG1, and IgG and IgG3 levels showed a significant positive correlation. These results showed that IgG subclasses could possibly be used as a helpful diagnostic marker in CL.
