It is recommended to investigate the serology of hepatitis B virus (HBV) and vaccinate seronegative patients at the time of diagnosis in inflammatory bowel diseases (IBD). This study aimed to investigate the efficacy of HBV vaccine and factors affecting the response.In this retrospective, observational study, HBV-seronegative IBD patients were administered 3 doses (at months 0, 1, and 6) recombinant 20 μg HbsAg. Patients’ demographics, IBD attributes, and treatment methods were investigated as the factors with potential impacts on vaccination outcomes.One hundred twenty-five patients with IBD were evaluated. The number of patients with Anti-HBs >10 IU/L was 71 (56.8%), and the number of patients with anti-HBs >100 IU/L was 50 (40%). Age, disease activity, Crohn disease subtype, and immunosuppressive treatment (IST) were found to have significant effects on immune response (P = 0.011, P < 0.001, P = 0.003, and P < 0.001, respectively). With multivariate analysis, age < 45 years (OR 3.1, 95% CI 1.2–8.3, P = 0.020), vaccination during remission (OR 5.6, 95% CI 2.3–14, P < 0.001), and non-IST (OR 11.1, 95% CI 2.9–43.2, P = 0.001) had favorable effects on the occurrence of adequate vaccine response.The likelihood of achieving adequate immune response with standard HBV vaccination protocol in IBD is low. Selecting vaccination protocols with more potent immunogenicity is a better approach to achieve effective vaccine response in patients with multiple unfavorable factors.

Infective endocarditis caused by Gemella morbillorum is a rare disease. In this report 67-year-old male patient with G. morbillorum endocarditis was presented. The patient was hospitalized as he had a fever of unknown origin and in the two of the three sets of blood cultures taken at the first day of hospitalization G. morbillorum was identified. The transthoracic echogram revealed 14 × 10 mm vegetation on the aortic noncoronary cuspis. After 4 weeks of antibiotic therapy, the case was referred to the clinic of cardiovascular surgery for valve surgery.

Infections and outbreaks of vancomycin-resistant enterococci (VRE) still appear to be rare in Turkey. In the present study, VRE strains isolated during an outbreak in a haematology unit of a training and research hospital in Turkey were typed and their antimicrobial-resistance patterns were characterized by molecular methods. Twelve vancomycin-resistant Enterococcus faecium strains isolated from patients with haematological malignancies were investigated by PCR for the presence of genes encoding resistance to vancomycin, tetracycline, chloramphenicol, gentamicin and erythromycin. Their clonal relationship was evaluated by PFGE and multilocus sequence typing. All strains were resistant to vancomycin and erythromycin, and had the vanA and ermB genes, respectively. PFGE was used to determine the presence of two pulsotypes and determine their subtypes. Pulsotype A belonged to sequence type (ST) 17 and pulsotype B belonged to ST 78. All strains with the vanA gene were not the same clone, indicating multiple acquisitions of resistant isolates, even over such a short time period.
