The Experience of Vaccination of a Patient With Juvenile Idiopathic Arthritis With Frequent Respiratory Infections With a Pneumococcal 13-Valent Conjugate Vaccine During Methotrexate Therapy

Abstract

The article presents the experience of vaccination with a pneumococcal 13-valent conjugate vaccine (PCV13) of a patient aged 5 years with oligoarticular juvenile idiopathic arthritis (JIA) receiving methotrexate at a dose of 15 mg/m2 per week subcutaneously. Treatment with methotrexate provided a remission of JIA, but was accompanied by frequent respiratory infections — up to 8 times a year. During infection progression, methotrexate injections were omitted. Gaps in the treatment with methotrexate were accompanied by an exacerbation of the underlying condition. Vaccination of the patient with PCV13 reduced the frequency of respiratory infections to 2 times a year, which was accompanied by the development of persistent remission of the disease. Adverse events and exacerbation of JIA in a child after vaccination with PCV13 were not registered.
