Abstract

Background : With the rapid evolution of assisted reproductive technologies, more and more studies are concerned about the possible influential factors on the success rates of these procedures, with the efforts are now mainly directed toward defining these factors in a trial to increase these rates. Of these factors, inflammation is considered among the most remarkable and is in the focus of the updated studies. However, most of these studies are evaluating the role of inflammation in patients with polycystic ovarian syndrome(PCOS) , while the impact of this inflammation in insulin resistant non PCOS patients is underesti­ mated and not well evaluated . Objectives: This study is a trial to elucidate the importance of one of the inflam­ matory mediators , Tumor Necrosis Factor-alpha (TNF – α) , in insulin resistant patients undergoing IVF ( ICSI ) cycles . Patients and Methods: A group of 27non-PCOS infertile patients were select­ ed for this clinical randomized prospective study from patients attending the high institute for infertility diagnosis and assisted reproductive technologies / Al-Nahrain University and subjected to intra-cytoplasmic sperm injection (ICSI) procedure. BMI was measured for all patients and they were classified according to WHO classification into 3 groups : Acceptable , overweight and obese . Fast­ ing plasma level of glucose and insulin was investigated and insulin resistance index (HOMA) was calculated. Serum TNF-α has been measured using ELISA and the relation with insulin resistance was investigated. Finally, the pregnancy rate, as a primary reproductive endpoint was compared according to TNF -a and insulin resistance levels between different study subjects. Results: Of the 27 infertile patients , 17(63 %) were non obese and 10 (37%) were obese , 15(55.5%) were having HOMA index < 1.6 and 12 (44.5 %) were having HOMA index ≥ 1.6 . BMI was found to be positively correlated with high­ er HOMA index ( P = 0.01 and R= 0.4 in spearman correlation). Investigating the relation between TNF-α with BMI revealed that TNF-α levels are increasing with the increment in BMI, However , the difference in the mean TNF-α between the three BMI groups failed to achieve statistical significance (P=0.1). In contrast to that, when stratifying for HOMA index , TNF-α was significantly correlated with it ( spearman correlation R= 0.4 , P=0.01 ) , and patients with HOMA index ≥1.6 were found to have higher levels of TNF-α ( P = 0.03) and to be more obese ( P=0.02 ) than those with HOMA index <1.6.
