RESUMO
AIM: Microbiota of the reproductive tract may be associated with unexplained infertility in women. We aimed to determine the derangements of vaginal and endometrial microbiota related to unexplained infertility by real-time polymerase chain reaction (real-time PCR) microbiota analyses of vaginal and endometrial samples of the unexplained infertility patients and fertile women. MATERIALS AND METHODS: Twenty-six women with unexplained infertility and 26 age-matched fertile women were included. Vaginal and endometrial samples were obtained in the mid-menstrual cycle for analysis by quantitative real-time PCR method. RESULTS: The proportion of lactobacilli-impaired microbiota was significantly higher in the vaginal samples of unexplained infertility patients (76.9% vs. 26.9%; p < 0.001). Those with impaired lactobacilli microbiota of vaginal samples had an increased risk of 9.048 times for infertility than those with normal lactobacilli microbiota. In addition, the mean lactobacilli/total bacterial mass (TBM) ratio in the vaginal samples was significantly lower in the unexplained infertility patients (38.2% vs.76.3%; p = 0.001). CONCLUSION: The present study results supported the role of vaginal and endometrial microbiota derangements in unexplained infertility. Many time-consuming and invasive methods are currently used in the diagnosis of infertility. Our study showed that the quantitative determination of lactobacilli/TBM ratio in vaginal specimens, a less invasive and easily obtainable method, could be used as a diagnostic test during the workup of couples with unexplained infertility.

This study aimed to examine the relationship between Hb A1c levels and the clinical course of coronavirus-19 (COVID-19) patients. Sixty-six COVID-19(+) patients with high Hb A1c and 46 with average Hb A1c and 30 COVID-19(-) patients with average Hb A1c were included. Hb A1c levels and parameters examined in COVID-19(+) patients were compared between groups, and correlation analysis was performed between these parameters and Hb A1c levels. The effect of Hb A1c levels on intensive care unit (ICU) admission and mortality rate in COVID-19 patients was analyzed with the χ2 test. It was observed that hemoglobin (Hb) and arterial oxygen saturation (SaO2) levels of the COVID-19 (+) groups was lower than the COVID-19 (-) group, while ferritin, D-dimer, procalcitonin (PCT), and C-reactive protein (CRP) levels were higher. The COVID-19 (+) group with high Hb A1c had higher lactate dehydrogenase (LDH), PCT and D-dimer levels than the other two groups, while Hb, partial arterial oxygen pressure (PaO2) levels were lower. The Hb A1c levels of the COVID-19 (+) groups were positively correlated with absolute neutrophil count (ANC), LDH, PCT and (K+) levels, while negatively correlated with Hb and PaO2 levels. Hb A1c was found to be associated with the inflammation process, coagulation disorders and low PaO2 in COVID-19 patients. The COVID-19 patients with high Hb A1c levels had a higher mortality rate than other COVID-19 patients. Using Hb A1c measurements with other prognostic markers would contribute to the patient's risk of death assessment.

Background/aim: The effectiveness of inhaled corticosteroids (ICSs) in cystic fibrosis (CF) is controversial. The aim of this study was to investigate the effect of an ICS on bronchial hyperreactivity (BHR), oxidative status, and clinical and inflammatory parameters in CF patients. Materials and methods: CF patients were randomized to receive either 2 mg/day nebulized budesonide or 0.9% normal saline as placebo for 8 weeks. Results: Twenty-nine CF patients (mean age: 10.5 ± 2.9 years) were enrolled in the study. There was no statistically significant difference between the two groups at the end of 8 weeks in terms of symptoms, pulmonary function, BHR, oxidative burst, hs-CRP, or ESR. Although there was a significant decrease in malondialdehyde levels in both groups, there was no difference between the two groups. Percentage of neutrophils in the sputum of patients decreased in the budesonide group (P = 0.006). Although sputum IL-8 levels significantly increased in both groups, there was no statistically significant difference between the two groups. Conclusion: Although there was a significant decrease in the percentage of neutrophils in sputum with budesonide, 8 weeks of 2 mg/day nebulized budesonide was not effective in terms of BHR, oxidative status, or clinical and other inflammatory parameters in children with CF.
RESUMO
BACKGROUND: Coronavirus disease 2019 (COVID-19) is a multisystem disease of global significance. Interleukin (IL)-6 is a soluble cytokine with a pleiotropic effect on inflammation and the immune response. OBJECTIVES: Investigate the relationship between the interleukin 6 (IL6) rs1800795 variant and IL6 level in Turkish patients with COVID-19 disease. DESIGN: Prospective cohort study. SETTING: Tertiary care hospital. PATIENTS AND METHODS: Real-time polymerase chain reaction (RT-PCR)-positive and/or chest computerized tomography (CT) scan-compatible COVID-19 patients were enrolled in the study. The clinical data and whole blood samples were collected from April 1, 2020, to August 1, 2020. IL6 rs1800795 genotyping was performed by the PCR-restriction fragment-length polymorphism (RFLP) method in 148 patients. Serum IL-6 concentrations were measured using the ELISA method in 89 patients. We evaluated the patients in three groups: asymptomatic, symptomatic, and intensive care unit patients. MAIN OUTCOME MEASURES: IL6 rs1800795 genotype frequencies and serum IL-6 levels in COVID-19 patients with different clinical presentations. SAMPLE SIZE: 148 cases. RESULTS: IL6 rs1800795 GG genotype and G allele frequency increased in PCR positive patients compared to PCR-negative patients (p Ë 0.000). IL6 rs1800795 GC genotype and C allele frequency were lower in PCR-positive patients than in PCR-negative patients. IL6 rs1800795 GG genotype and G allele frequency were higher in asymptomatic patients than in the symptomatic and intensive care unit groups. The IL6 rs1800795 C allele frequency was lower in asymptomatic patients than in the symptomatic and intensive care unit groups. IL6 rs1800795 GG genotype and G allele frequency were higher in CT negative patients than CT positive patients, while IL6 GC genotype and C allele frequency were higher in CT positive patients than negative patients. IL6 level elevation was seen in the asymptomatic patients compared to the symptomatic and intensive care unit groups. CONCLUSIONS: These findings suggest that IL6 rs1800795 may contribute to the susceptibility of COVID-19 in people to Turkish origin. LIMITATIONS: Further large-scale studies in different genetic populations are needed as this is a single-center, prospective study.
