Serum levels of interferon gamma INF-γ and interleukin 10 il-10: An immunological aspect among irritable bowel syndrome patients

Background and Objective: The pathophysiological mechanisms of irritable bowel syndrome are controversial and the exact mechanism that play role in exaggeration of symptoms is mysterious. As an altered immunological functions in IBS patients may play role to study pro and anti-inflammatory cytokines among the study population. The aim of this study is to examine the serum cytokines of IL 10 and INFγ profile among a group of IBS patients and control. Materials and Methods: A cross sectional prospective study was conducted among 40 participants, who were referred to gastroenterology out patients clinics at Khartoum Teaching Hospital, Khartoum State, Sudan. Five milliliters blood were collected in EDTA tubes for measuring levels of cytokines in serum. Cytokines were measured by ELISA-MSD (Meso Scale Discovery). They were measured according to the manufacturer’s instructions and expressed as pg mL^-1. Optical density was measured at a wavelength of 450 nm and a reference wavelength of 590 nm. Results: Out of 16 (40%) male and 24 (60%) female, their age group range between 20-70 years old. The majority of them 21(52.5%) in age group (31-50) years old. Overall IBS patients showed significantly increased (p = 0.0001) of INF-γ (29.50±17.98 vs. 6.9±1.724 pg mL^-1) between patients and control, respectively. The serum levels of IL-10 was significantly higher in patients with IBS compared with control group (p = 0.001). Conclusion: There is an abnormal immune regulation, supporting the presence of immune activation in IBS.
