Preservation of Postvaccinal Immunity to Measles, Rubella, Parotitis, Hepatitis B and Diphtheria in Patients With Juvenile Idiopathic Arthritis Who Undergone Planned Immunization Under the Age of Two: Preliminary Results of Cross-Sectional Study

Background. Vaccination is the most effective method for reducing morbidity, disability, mortality from of various infections. However, there was a view for a long time that vaccines are ineffective and unsafe to use in people with rheumatological diseases, including juvenile idiopathic arthritis (JIA). Objective.The aim of the study is to analyze literature data on safety and efficacy of vaccination for JIA patients with live and non-live vaccines.Methods: literature analysis was based on data from medical databases PubMed and Google Scholar.Results. Both live and non-live vaccines are safe and immunogenic enough for children with JIA. Most studies confirm vaccination efficacy in patients with JIA when using glucocorticosteroids (GCS) and methotrexate, while therapy with disease-modifying antirheumatic drugs (DMARD) can reduce antibody titers over time. In general, antibodies levels preservation in previously vaccinated children with JIA is less than in global population. This indicates the need to administer booster doses for such patients. No adverse effects on the course of primary disease after vaccination and no post-vaccine complications were revealed.Conclusion. Vaccination of patients with JIA should be performed with reference to the therapy that the patient already receives, under the control of antibodies level. Booster doses should be implemented in case of titers decrease below the protective levels.

Vaccination against viral hepatitis B is an effective method of protection against this infection. There is multiple decrease in the hepatitis B incidence. However, there was increase in chronic hepatitis B by 42.5%, 15 cases of acute viral hepatitis B in children and 2 deaths from this infection were registered according to the state report “On the sanitary and epidemiological wellbeing of the population of the Russian Federation for 2022”. The criteria for evaluating protection against viral hepatitis B are the anti-HBs level and the duration of post-vaccination immunity.Objective. The aim of the study is to evaluate the duration of postvaccination immunity in temporal aspect in children and adolescents vaccinated against viral hepatitis B.Methods. Prospective open-label study was conducted to assess post-vaccination immunity against viral hepatitis B in 143 children and adolescents. The study of anti-HBs was implemented via the immunoenzyme test system “Vectohep B-HBs-antigen”. Microsoft Office Excel 2010 package and the Prism9 program (GraphPad, USA) were used for statistical analysis.Results. It has been shown that hepatitis B vaccine provides 100% seroconversion. However, decrease in anti-HBs levels was revealed already 6 months after vaccination in 15.07% of cases of seronegative individuals, after 1 year their number has increased up to 28.77% of cases. On average, every fourth person had low protective level of anti-HBs. Almost two-thirds of adolescents became seronegative by the age of 14.Conclusion. Vaccination against viral hepatitis B ensures the maximum production of anti-HBs 1 month after the completed vaccination in 100% of cases. Antibody level begins to decrease 6 months after the third completed vaccination against hepatitis B, and in 14 years, 72.74% of those immunized become seronegative. All of these dictates the need to consider a booster dose in adolescents at the age of 14 years.
