Comparison of Serum Levels of Soluble CD26 and CD30 in Patients with Brucellosis and Controls
Abstract
BACKGROUND AND OBJECTIVE: Brucellosis is a zoonotic disease in the world. It has been shown that host resistance to brucella bacteria depends on Th1 response, whereas Th2 response is involved in the severity of the disease. It is suggested that CD26 and CD30 are surface molecules expressed on activated Th1 and Th2 cells, respectively. The aim of the present study was to determine the levels of soluble (s) CD26 and CD30 molecules in sera of brucellosis and healthy controls.METHODS: The study included 90 brucellosis patients and 70 healthy controls. Brucellosis was diagnosed base on clinical findings, microbiologic or/and serologic findings. The levels of sCD26 and sCD30 were determined by a sandwich enzyme-linked immunosorbent assay in sera of study population.FINDINGS: Serum levels of sCD26 were 847.07±249.7 and 504.97±165.6 ng/ml in brucellosis and controls, respectively, which shown a significant difference (p<0.0001). Meanwhile, there was no significant difference in sCD30 levels between brucellosis and controls (51.33±35.9 and 42.75±20.87 IU/ml).CONCLUSION: These findings indicate that assessment of sCD26 and sCD30 levels are a valuable and quick method for evaluating immune response to brucellosis.
