CD26 and CD30 are surface molecules expressed on activated Th1 and Th2 cells, respectively. It is, therefore assumed that plasma levels of CD26 and CD30 (sCD26 and sCD30) correlate with Th1 and Th2 response, respectively. In this study, plasma levels of sCD26 and sCD30 in patients with non-healing form of cutaneous leishmaniasis (CL) were measured and compared with the levels of sCD26 and sCD30 in patients with healing form of CL and healthy control volunteers. The results indicate that the plasma levels of sCD26 and sCD30 are significantly (p<0.05) higher in patients with non-healing form of CL than patients with healing form of CL or healthy control. No significant difference is seen in the levels of sCD26 and sCD30 in patients with healing form of CL in comparison with healthy control group. It is concluded that sCD30 might be used as an indicator of a Th2 response in patients with non-healing form of CL.
