“…Anti-HBs, on the other hand, indicates immunity after infection or vaccination (12). Therefore, the use of these screening tools to determine the sufficient antibody response in unvaccinated individuals or even in vaccinated individuals, and to detect possible hepatitis B infected individuals is particularly crucial, especially before dental procedures involving direct contact with the patient (13)(14)(15).…”

Background/Aims: Hepatitis B virus infection continues to be a major global and national public health concern. The aim of this study was to examine the seroprevalence of hepatitis B virus in children who were consulted to child health and diseases before dental intervention and to share our findings with the healthcare personnel involved on this subject. Methods: A total of 932 children were enrolled in the study, of which 533 (57.2%) were boys and 399 (42.8%) were girls. In the blood samples taken; hepatitis B virus tests were studied with the Enzyme Linked Immuno Sorbent Assay method. The results of blood samples and demographic data of the patients were evaluated. Results: HBsAg positivity was not found in any of the patients (0%). AntiHbs seropositivity was found in 73.8% of the whole patient population. No statistically significant difference was detected when comparing the anti-HBs levels based on gender. The average age of children with antiHbs seropositive was found to be statistically significant lower than that of those with antiHBs negative. The median anti-HBS antibody levels were significantly higher in the group of children under 5 years old than in the other two age groups older than five years old in our study. When investigating the association between the level of antiHBs and age, a weak negative correlation was found. Conclusions: Our study showed that the antiHbs seropositivity is higher in Konya compared to previous studies. It suggests that the national vaccination program has a positive impact on antiHbs seroprevalence. Our study revealed that children under the age of five displayed the highest levels of anti-HBs seropositivity, while the anti-HBs levels diminished with advancing age.

Objective: Childhood cancer treatment disrupts vaccination schedules and weakens or eliminates vaccine-induced immunity. In addition, post-treatment vaccine responses vary. This study aimed to assess post-treatment serum antibody levels and vaccine responses in children. Methods: Pediatric patients treated at Hacettepe University between years 2015 and 2020, achieved remission after chemotherapy for lymphoma and solid tumors were included. Post-treatment vaccination status, serum antibody levels for hepatitis A (HAV), hepatitis B (HBV), varicella-zoster (VZV), measles-mumps-rubella (MMR), and changes in vaccine responses were retrospectively analyzed. Results: The study included 533 patients. Post-treatment seronegativity rates were: measles (83.5%), HAV (64%), rubella (60.1%), HBV (48.5%), VZV (43.3%), and mumps (28%). Post-treatment antibody loss was observed for measles (47.1%), HAV (31.9%), HBV (31.4%), mumps (28.6%), VZV (21.7%), and rubella (11.4%). Seropositivity after 1 vaccine dose was seen with HAV (83.6%), rubella (82.9%), HBV (81.4%), VZV (63.5%), mumps (45.4%), and measles (33.3%). Seropositivity after 2 vaccine doses was achieved with HAV (98.8%), VZV (84.6%), rubella (80%), HBV (80%), measles (32.2%), and mumps (36.2%). Conclusion: Post-treatment serological vaccine responses in children were lower than anticipated despite multiple doses. Given the potential need for periodic serological assessments and booster vaccinations, long-term follow-ups are planned.

Background The incidence of Hepatitis A is increasing worldwide. Yearly classification of Hepatitis A Seroprevalence for different times in different regions of Türkiye allows indirect measurement of year-specific incidence rates of HAV infection and can be considered the best way to define Hepatitis A status. This study aimed to examine the change in the incidence of hepatitis A by systematically evaluating the available data on the seroprevalence of anti-HAV antibodies in the Turkish population. Methods Studies published between First January, 2000- 31 December 2023 that meet the inclusion criteria searched between 16.09.2023 and 31.01.2024 in nine databases (MEDLINE, Web of Science, PubMed, ScienceDirect, Scopus, Eric, CINAHL Complate, TR DİZİN, TÜBİTAK Ulakbim). Independently by two reviewers evaluated all titles and abstracts with consensus-based decision making. The Joanna Briggs Institution (JBI) Analytical Cross Sectional Studies and Prevelance Studies list were used in this study. Pooled prevalence was calculated using 95% confidence intervals. Heterogeneity between studies was assessed by Cochrane’s Q and I2. The random effect model was selected by Cochrane’s Q and I2. Funnel plots were used for publication bias. The data were analyzed via Jamovi 1.2.22. Results Data were extracted from 63 studies. Pooled prevalence was calculated using 95% confidence intervals. Funnel plots were used for publication bias. In this meta-analysis, data were obtained from all geographical regions of Türkiye, and the general prevalence of Hepatitis A in the population was found to be 53% [95% CI 0.47, 0.59; I2 = 99.94%]. In subgroup analysis conducted by year, the prevalence of hepatitis A was 45% [95% CI 0.22, 0.67; I2 = 99.8%] between 2002 and 2006, 52% [95% CI 0.39, 0.65; I2 = 99.54%] between 2007 and 2011, 60% [95% CI 0.49, 0.70; I2 = 99.9%] between 2012 and 2016, and 51% [95% CI 0.41, 0.61; I2 = 99.97%] as of 2017. Additionally, a systematic review revealed that vaccination, socioeconomic status, and sex may also affect HAV seroprevalence. Conclusions HAV seroprevalence in Türkiye; It was observed that it increased between 2002 and 2016 and decreased until today as of 2017. This systematic review provide a comprehensive overview of HAV virus epidemiology and identify key knowledge gaps, contributing crucial information for influencing factors. Trial registration PROSPERO ID = CRD42023464384.
