Objective Polycystic ovary syndrome (PCOS) is a heterogeneous endocrine and metabolic disorder characterized by hyperandrogenism, hyperinsulinemia, and insulin resistance. The prevalence of PCOS is increasing worldwide. Although the etiology of this disease is currently unknown, it is thought to be closely related to inflammation and oxidative stress. Our study aimed to compare patients have PCOS to healthy volunteers and assess the changes in oxidative stress and inflammatory parameters in these patients. Methods Thirty patients between the ages of 18-45 diagnosed with PCOS and 30 healthy volunteers with the same demographic characteristics were included in this study. Clinical parameters were measured using immunoassays. Oxidative stress biomarkers, total oxidant (TOS), total antioxidant (TAS), total thiol (TT), and native thiol (NT) levels were measured using photometric methods according to Erel’s method. The dynamic disulfide level (DIS) and oxidative stress index (OSI) were calculated using mathematical equations. Among the inflammatory parameters, values for interleukin (IL)-1β, IL-6, and tumor necrosis factor-α (TNF-α) were measured photometrically using commercially purchased kits. Results Moreover, TT and NT levels were lower in patients with PCOS compared to those in the healthy group statistically significantly (P<0.001). In addition, TAS, TOS, OSI, DIS, IL-1β, IL-6, and TNF-α levels were identified to be significantly higher in the patients with PCOS than those in the healthy group (P<0.001). Conclusion Evaluation of oxidative stress and clinical parameters used in the follow-up may be beneficial for the disease.

Objective: The present study was conducted to evaluate invasive and noninvasive diagnostic methods for detection of Helicobacter pylori (H. pylori) in patients admitted with dyspeptic complaints and to compare sensitivities and specificities. Method: Sets of four gastric biopsy specimens were obtained from a total of 126 patients included in the study. The presence of H. pylori was determined by invasive tests including culture, rapid urease test, polymerase chain reaction (PCR) and histopathology. Among noninvasive tests, urea breath test, serological tests and enzyme-linked immunosorbent assay (ELISA) were performed. Results: H. pylori was isolated in 79 (62.7%) gastric biopsy cultures, whereas positivity was concluded for 105 (83.3%) patients by rapid urease test, for 106 (84.1%) by PCR, for 110 (87.3%) by histopathology, for 119 (94.4%) by urea breath test, and for 107 (84.9%) by ELISA. In the present study, the culture findings and histopathological examination findings were accepted as gold standard. According to the gold standard, urea breath test had the highest sensitivity (96.5%) and the lowest specificity (30%), whereas culture and histopathology had the highest specificities (100%). Conclusion: The use of PCR invasively with gastric biopsy samples yielded parallel results with the gold standard. PCR can be recommended for routine use in the diagnosis of H. pylori.
