Acute hepatitis B outbreak in a nursing home for the disabled in Türkiye.

Background: Although hepatitis B is vaccine-preventable, it remains a significant health problem. To the best of our knowledge, this is the first hepatitis B outbreak report from Türkiye. Aims: To investigate the cause of hepatitis B outbreak in a nursing home for the disabled and make recommendations for prevention. Methods: An outbreak of acute hepatitis B was declared in a nursing home for the disabled following the admission of 3 patients from the home in a hospital. Collaborative response was initiated with the Provincial Health Directorate through the Public Health Infectious Diseases Department. We began tracking the infection and monitoring active cases. Audits and controls were carried out to determine the source, establish protection and control measures, and prevent further transmission. Results: Six of the 65 nursing home residents were diagnosed with acute hepatitis B. Four of them had diabetes and their blood glucose levels were monitored for at least 12 months. Two of the patients had received dental treatment in the last 6 months. The frequency of both variables, which may be an indication of the transmission route, was statistically significantly greater in the acute hepatitis B group. All the patients who could be sequenced were identified as genotype D. While 3 patients recovered fully, 2 were diagnosed with chronic hepatitis B and one died due to fulminant hepatitis. Conclusion: Standard routine immunization should be implemented as a preventive measure for acute hepatitis B. Frequent supervision and training on hygiene practices and safety precautions should be conducted for care staff working in collective residential facilities.

Gastrointestinal PCR panel results and antibiotic use in acute gastroenteritis cases: How appropriate are we in our usage?

BACKGROUND: We aimed to determine the pathogens detected by the Gastrointestinal (GI) PCR panel in patients with acute gastroenteritis (AGE), the evaluation of antibiotic use in these patients, and the investigation of the role of laboratory parameters in differentiating viral and bacterial etiologies. METHODS: The demographic characteristics, GI PCR panel results, laboratory investigations, antibiotic usage, and appropriateness of antibiotic treatment were investigated in AGE patients. RESULTS: A total of 175 adult patients with AGE and GI PCR panel results were included in the study. The most common pathogens were EPEC (24.6%) and C. difficile (18.3%). Among the 102 patients receiving antibiotic treatment, 34.3% were evaluated as inappropriate antibiotic use. WBC, CRP, procalcitonin, CRP/albumin ratio, and procalcitonin/albumin ratio were found to be significantly higher in cases with bacterial origin. CONCLUSIONS: The utilization of GI PCR panels in AGE patients has revolutionized the field of diagnostics by providing rapid and accurate identification of pathogens. In units without the possibility of GI PCR testing, CRP, procalcitonin, CRP/albumin ratio and procalcitonin/albumin ratio may be useful in the decision of antibiotic treatment.
