Comparing IL-5, IL-10, IL-12, and IL-18 Cytokines Levels Secreted From the PBMCs of Patients with Healing and Nonhealing Skin Leishmaniasis

Introduction & Objective: Leishmaniasis is a major worldwide health problem throughout the world and in Iran as well. Skin lesions are mostly healing but nonhealing cases have also increased recently. T-helper type1 (Th1) responses induction helps the patients to resist against the disease while T-helper type2 (Th2) responses cause susceptibility to disease. With the assessment of IL-5, IL-10, IL-12, and IL-18 cytokines secreted from peripheral blood mononuclear cells (PBMC) in leishmaniasis healing and nonhealing patients, their role in curing leishmaniasis was surveyed. Materials & Methods: Cytokines secreted from PBMCs of 60 healing and nonhealing patients and also control group referred to Ab-o-Bargh number1 clinic and Mashhad Qaem hospital during 2007 were evaluated Elisa commercial kits after stimulation by leishmania antigen and mitogen in vitro. Results: Healing patients PBMCs secreted IL-12 (236.55±38.00 pg/ml) more than non healing patients (p
