Treatment of Helicobacter Pylori Infection and the Colonization of the Gastrointestinal System by Resistant Bacteria.

BACKGROUND AND AIMS: Helicobacter pylori (H. pylori) infections are widely treated with antibiotic regimens such as "Amoxicillin 1 gr 2 × 1 tablet, Clarithromycin 500 mg 2 × 1 tablet, and Lansoprazole 30 mg 2 × 1 tablet" for 14 days. We conducted a prospective observational study to explore whether this treatment protocol serves as a predisposing factor for the colonization of resistant gastrointestinal microflora, namely vancomycin-resistant enterococci (VRE), extended-spectrum beta-lactamase Enterobacterales (ESBL-E), and carbapenem-resistant Enterobacterales (CRE). MATERIALS AND METHODS: Pre- and post-treatment stool samples from 75 patients diagnosed with H. pylori, without a prior treatment history, were cultured and evaluated based on the European Committee on Antimicrobial Susceptibility Testing (EUCAST) criteria. RESULTS: Of the 75 evaluated patients, a pronounced surge in ESBL-E positivity was observed. Before initiating antibiotic treatment, 12 patients (16%) had ESBL-E-positive strains in their gastrointestinal tract. Notably, this number surged to 24 patients (32%) after the conclusion of the 14-day treatment regimen. The change was statistically significant, with a P value of less than 0.002, indicating a clear association between treatment for H. pylori and heightened ESBL-E colonization. Notably, VRE and CRE remained undetected in patients throughout the study, suggesting that the treatment regimen may specifically amplify the risk of ESBL-E colonization without affecting VRE and CRE prevalence. CONCLUSIONS: As the inaugural report from Turkey on this issue, our study suggests that antibiotic regimens for H. pylori eradication contribute to the increased risk of ESBL-positive bacterial colonization in the gastrointestinal tract.

The role of chest X-ray in coronavirus disease 2019 (COVID-19) infection: findings and correlation with clinical outcome.

OBJECTIVE: It is possible to diagnose coronavirus disease 2019 (COVID-19) faster and more accurately with chest X-ray (CXR) and chest computed tomography (CT) than with reverse transcriptase PCR (RT-PCR) tests. The aim of this study was to verify the possibility of reducing the use of CT in diagnosis and follow-up of COVID-19 infection by using CXR. PATIENTS AND METHODS: A total of 326 COVID-19 patients who were hospitalized in Ankara City Hospital were included in this retrospective study. RESULTS: A total of 326 patients were RT-PCR positive for COVID-19 infection; 178 were male (54.6%) and 148 were female (45.4%), with a median age of 45. Considering the results, the baseline CXR sensitivity in our experience was approximately 72%. The CXRs of 113 patients with abnormal CT were divided into 2 groups, the CXR normal and abnormal groups, and were then compared. In the 1st group with abnormal CXR, the mean age, the number of patients over 65 years old, and the comorbidity rate were higher. Additionally, it was determined that the number of patients requiring respiratory support and intensive care unit (ICU) admission in this 1st group was higher than in the 2nd group (with normal CXR). Most of the patients who died (91%, 10/11) were in Group 1. In the group with normal CXR, no patients in the critically ill category needed invasive or non-invasive mechanical ventilators. CONCLUSIONS: CXR can help in detecting clinically moderate and severe cases of COVID-19. CXR can assist clinicians in patient management and treatment planning regarding the clinical course, respiratory support, ICU need, and mortality and can help them prepare for potential negative outcomes.

The impacts of the COVID-19 pandemic on patients with viral hepatitis B infection: follow-up, compliance with antiviral treatment, and vaccine preferences.

OBJECTIVE: Elimination programs and interventions for patients with viral hepatitis B (HBV) have been disrupted during the COVID-19 pandemic. This study aimed to evaluate the effects of the COVID-19 pandemic on patients with HBV infection in terms of COVID-19 vaccine preferences, follow-up visits, and antiviral treatment compliance. PATIENTS AND METHODS: In this retrospective single-center cross-sectional study, 129 patients with viral hepatitis B infection were evaluated. The patients were surveyed at the time of admission. A special form was created for patients with viral hepatitis B infection, and the form contained information about the patients at admission to collect the study data. RESULTS: A total of 129 participants were included in the study. Of the participants, 49.6% were males and the median age was 50 years. In total, 73 (56.6%) patients had their follow-up visits disrupted because of the COVID-19 pandemic. No newly diagnosed case of HBV infection was detected. Among the 129 patients, 46 had inactive hepatitis B, and 83 had chronic hepatitis B infection and were receiving antiviral treatment. None of the patients had trouble reaching antiviral treatments during the COVID-19 pandemic. A liver biopsy was recommended for 8 patients. Half of these 8 patients did not have follow-up visits during the COVID-19 pandemic. Most of the patients (123/129, 95.3%) received the COVID-19 vaccine and the most frequent vaccine that was used was the Pfizer-BioNTech (n: 92, 71.3%) vaccine. Serious side effects of the COVID-19 vaccines were not detected. Mild side effects were found in 41.9% (13/31) of the patients. The COVID antibody level was found to be statistically and significantly higher in the patients who received the Pfizer-BioNTech vaccine than in those that received the CoronoVac vaccine. CONCLUSIONS: It was reported that elimination programs and interventions for HBV infection decreased or stopped because of the COVID-19 pandemic. In the present study, no newly diagnosed case of HBV infection was detected. Most of the patients had their follow-up visits disrupted. There were no patients who could not receive antiviral treatment, the vaccination rate of the patients was high, and the vaccines were well tolerated.
