Serum levels of soluble interleukin-2 receptor in association with oxidative stress index in patients with different types of HPV

Objectives: The aim of this paper is to determine the oxidative-antioxidative status and levels of soluble interleukin-2 receptor (sIL-2R) in serum of patients with different types of HPV infections and to compare it with patients who are negative for HPV. Material and methods: A total of 80 women were divided into three groups as follows: Group 1 consisted of 25 women who were positive for HPV types 16 or 18; Group 2 consisted of 25 women who were positive for other types of HPV including type 31, 33, 35, 39, 45, 51, 52, 56, 58, 59 or 68; Group 3 consisted of 30 patients who were negative for HPV as a control group. Serum sIL-2R and plasma oxidative stress index (OSI) were analyzed. Results: Serum sIL-2R levels were significantly higher in group 1 compared to group 2 and 3. OSI was found significantly increased in groups 1 and 2 compared to group 3. Also, we found a weak positive correlation between IL-2R and OSI. Conclusion: sIL-2R and oxidative stress may have a role in HPV infection, especially in case of high-risk types.
