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.
Background. Syndecan-1 (SDC-1), a member of the family of heparan sulfate proteoglycans, plays an important role in the resolution of inflammation. This study aimed to investigate the relationship between SDC-1 and disease activity in Crohn's disease (CD). Methods. Serum samples of 54 patients with CD and 30 healthy controls were obtained. First, SDC-1 levels of the CD patients were compared to the control group. Subsequently, SDC-1 levels were analyzed in patients with CD in active and remission periods. Finally, SDC-1 efficacy in predicting disease activity was evaluated by performing correlation analysis between SDC-1 and C-reactive protein (CRP) and Crohn's disease activity index (CDAI). Results. SDC-1 level was higher in the CD group (61.9 ± 42.6 ng/mL) compared with the control group (34.1 ± 8.0 ng/mL) (p = 0.03). SDC-1 levels were higher in active CD patients (97.1 ± 40.3 ng/mL) compared with those in remission (33.7 ± 13.5 ng/mL) (p < 0.001). A significant positive correlation was found between SDC-1 and CRP (r = 0.687, p < 0.001) and between SDC-1 and CDAI (r = 0.747, p < 0.001). Conclusion. Serum levels of SDC-1 are higher in CD compared to the normal population and can be an effective marker of disease severity.
Introduction: Splenic infarct is an unusual altitude. Generally, it arises from hematologic diseases and vascular and thromboembolic disorders.Case Report: A 79-year-old woman was admitted to our clinic with pain of the left upper region, emesis, vomiting, nausea, and cold sweat. The patient took beta-blocker and antiaggregant treatment for hypertension and atrial fibrillation. We detected rapid ventricular response atrial fibrillation on her ECG analysis. Also, abdominal CT was concordant with a splenic infarct. Her coagulation tests and sickle cell anemia tests were normal, which excluded hematological disorders (protein C, protein S, antithrombin III, Factor V Leiden mutation, homocysteine value, prothrombin 20210 A mutation, factor levels). We evaulated important risk factors as etiological causes for atrial fibrillation. Low-molecular-weight heparin (LMWH), oxygen, and intravenous hydration were started in the patient. Her complaints were decreased with time and showed clinical recovery.Conclusion: Our case is very interesting, because there is no frequent splenic infarct coexisting with atrial fibrillation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
