This study aimed to evaluate the relationship between no-reflow phenomenon and systemic inflammation index (SII) and to compare the predictive capacity of SII together with the neutrophil–lymphocyte ratio (NLR), and the platelet–lymphocyte ratio (PLR) in patients with ST-elevation myocardial infarction (STEMI). A total of 785 patients were included. The thrombolysis in myocardial infarction (TIMI) flow degree has been used to describe the no-reflow phenomenon. The study population was divided into two groups regarding the presence of no-reflow phenomenon including 110 patients with no-reflow (TIMI frame count 0-2) and 675 patients without no-reflow (TIMI frame count 3). The NLR [6.6 (4.6-11.6) vs 3.2 (2.0-5.3); P < .001], PLR [175 (121.3-220) vs 102.6 (76.1-150.1); P < .001] and SII [1921(1225-2906) vs 738.5 (450.5-1293); P < .001] were significantly higher in the no-reflow group. High NLR (OR: 1.078, 95%CI: 1.027-1.397; P = .021), PLR (OR: 1.009, 95%CI: 1.003-1.021; P = .041) and SII (OR: 1.216, 95%CI: 1.106-1.942; P = .004) were found to be independently associated with no-reflow phenomenon. The comparison of the receiver-operating characteristic curves showed that area under the curve of SII was greater than that of NLR (.789 vs .766, P = .007) and PLR (.789 vs .759, P = .048). SII levels may predict no-reflow phenomenon better than NLR and PLR.

The development of left ventricular hypertrophy (LVH) induced by hypertension is considered as a poor prognosis for patients. Similarly, high values of the systemic immune-in ammation index (SII) can be a leading cause for the increase of mortality and morbidity in cardiovascular events. Within this context, our study aimed to detect the association of SII with LVH caused by hypertension. The study encompassed 150 clients diagnosed with hypertensive in total, and evaluated them as two separate groups with regard to left ventricular mass index (LVMI), including 56 patients (37.3%) with LVH and 94 patients (62.6%) with non-LVH. The SII values regarding the group with LVH was detected remarkably higher than those of the non-LVH group (p<0.001). Additionally, the SII level of clients with eccentric and concentric hypertrophy was detected higher than those of the normal ventricular geometry and concentric remodeling groups. With regard to curve analysis of the receiver-operating characteristic (ROC), SII values above 869.5 predicted LVH with a sensitivity of 82.1% and speci city of 86.2% (AUC: 0.861; 95%CI: 0.792-0.930; p < 0.001). LVH can be predicted independently through the use of SII in clients diagnosed with hypertension, which may be a simple and easily calculable marker for judging LVH. Moreover, SII can serve as an accurate determinant for the prediction of LVH, in comparison to NLR and PLR.

This study was conducted to evaluate and compare the total antioxidant capacity among fertile and infertile men. Thirty infertile patients and 20 fertility-proven healthy donors with normal sperm analysis were included in the study. Total antioxidant capacity, zinc and fructose levels of seminal plasma, and various sperm parameters were compared among fertile controls and idiopathic infertility patients prospectively. The mean antioxidant capacity of fertile controls (2.02 +/- 0.16 mmol/L) was significantly higher than that of the infertile patients group (1.78 +/- 0.23 mmol/L) (p < .01). Furthermore, asthenozoospermic and asthenoteratozoospermic groups had significantly lower mean antioxidant values (1.73 +/- 0.11 and 1.64 +/- 0.13, respectively) when compared to fertile control group (p < .01). The mean fructose level was significantly lower in the fertile control group and mean zinc level was significantly lower in the entire infertile group. On the other hand, antioxidant capacity is positively correlated to sperm motility (p = .001). Decreased antioxidant capacity was associated with impaired sperm function as a result of either increased ROS production or insufficient antioxidant capacity.
