Determination (IL-36γ) Levels an‎d Study Of Its Relation With Other Cytokines In Iraqi Endometriotic Women

Endometriosis, an autoimmune disease is among one of the most challenging of the 21 st century that affects women in reproductive age. The aim of the present study is to highlight the role of IL-36γ, and its relationship with other cytokines (Ang-2 and TNF-α) in the pathogenesis of endometriosis . Seventy five (75) consecutive women patient of reproductive age (25-40) years were enrolled in this study , Patients were divided into three groups , group 1 (G1) included (25) newly diagnosed endometriotic patients , that were not given any treatment related to Gynecology or anti-inflammatory medications . Second group : group 2 (G2) consists of (25) endometriotic patient who were treated with zoladex for 3 to 5 months , they received zoladex injection every 28 day in the first day after diagnosis. The third group: Group 3 (G3) involved (25) patients with recurrent endometriosis , they were post treatment of zoladex and diagnosis revealed recurrence of endometriosis. Patients groups were compared with two control groups , with matched age with patients’ groups. The first control group (C) included (25) healthy women , and the second control group or pathological control group (PC) involved (25) women suffering from infertility caused by gynecological disorder unrelated to endometriosis.IL-36γ , Ang-2 and TNF-α were estimated in sera of studied groups. The results from this study revealed that IL-36γ levels were highly significant increase (p<0.001) and significant increase (p<0.05) in G1 comparing with groups C and PC respectively. While high significant decrease(p<0.001) was found in G2 comparing with G1. Also , there are no significant differences (p≥0.05) shown in G2 comparing with C group and in G3 comparing with G1.On the otherhand , Ang-2 levels were highly significant increased (p<0.001) and significant increase (p<0.05) in G1 comparing with groups C and PC respectively. While significant decrease (p<0.05) was found in G2 comparing with G1. Also , there are no significant differences (p≥0.05) in Ang-2 levels shown in G2 comparing with C group and in G3 comparing with G1 Our results also implied that TNF-α levels were highly significant increased (p<0.001) in G1 comparing with C group. While no significant differences (p≥0.05) was found in G1 comparing with PC group and in G3 comparing with G1. Also there are significant differences (p<0.05) shown in G2 comparing with G1 and C Our findings for endometriotic patient groups. A high significant difference was found between Ang-2 and TNF-α levels with IL-36γ for G1 , G2 and G3. The conclusion of this study reveals that IL-36γ could be considered a novel biochemical marker in endometriotic patients. Conclusion could be drawn from the results that endometriosis may be influenced on the cytokines secretion such as IL-36γ beside Ang-2 and TNF-α in G1 and G3 , suggesting that inflammatory / immunological factors associating with angiogenesis responses play crucial roles in the pathogenesis of endometriosis. Also, the results showed the role of zoladex in alteration immune responses as shown in G2. group.
