Background: Protozoa are unicellular eukaryotes. A type of intestinal protozoan pathogens is the cause of infection and serious injuries in human with or without clinical symptoms. It seems that parasitic infections as a stressor factor can affect on stress system activity and immune system function and sensitivity. The major purpose of this paper was to evaluate serum cortisol level and the general inflammation by measuring neutrophil to lymphocyte ratio in patients with intestinal protozoa. Methods: A total of 40 men were entered in a case-control study in Besat and Baqyiatallah (a.s.) Hospitals in Tehran from April to September 2014. Men were equally divided into 2 groups based on infection with the intestinal protozoa (control and patient groups). This study was conducted on blood samples of these people. Serum cortisol level and neutrophil to lymphocyte ratio were determined in control and patient with the intestinal protozoa groups. Cortisol was measured using cortisol kit (Diagnostic Biochem, Canada) and by ELISA method. In addition, the samples were treated with Wright stain method, and neutrophil to lymphocyte ratio was calculated using WBC diffraction method. Results: According to the results of this study, mean age between control and patient groups was not statistically significant (P= 0.91). Serum cortisol concentration in patients with the intestinal protozoa was significantly higher than the control group (P= 0.043). In addition, a significant increase was observed in neutrophil to lymphocyte ratio in patients with parasitic infections compared to the control group (P= 0.026). Conclusion: Based on the results of this study, parasitic infection (intestinal protozoa) as a stressor factor can increase serum cortisol concentration. In addition, intestinal protozoa was reduced immune system sensitivity and function. It seems that the neutrophil to lymphocyte ratio can be a potential useful parameters for evaluating the stress system activity and function in patients infected with the intestinal protozoa.
