RESUMO
INTRODUCTION/OBJECTIVES: To determine vaccination coverage among a French cohort of children with recurrent autoinflammatory fever syndromes (RFS). METHOD: All RFS children aged 2 to 19 years from the Juvenile Inflammatory Rheumatism cohort and followed at the French Reference Center for Autoinflammatory Diseases, Versailles Hospital, were included in our observational study. Immunisation status at ages 2, 7 and 15 years and at the last outpatient visit was evaluated according to the standard French vaccine schedule and recommended supplementary vaccines for patients with immunosuppressive therapy. RESULTS: Of 200 patients, 90 (45%) had periodic fever, aphthous stomatitis, pharyngitis and adenitis syndrome; 52 (26%) had familial Mediterranean fever and 50 (25%) had undefined recurrent fever. Complete immunisation as per the standard schedule was obtained by 32% of patients at 2 years, 28% at 7 years, 6% at 15 years and 44% at the last outpatient visit. Similar or higher coverage was obtained by the last outpatient visit for most vaccines, compared to immunisation coverage at 2 years: pneumococcus (91% vs 88%), diphtheria tetanus poliomyelitis (82% vs 86%), hepatitis B (79% vs 69%) and measles, mumps, rubella (91% vs 50%). No patients with immunosuppressive therapy (n = 14) were up to date for all supplementary immunisations recommended for them. CONCLUSION: Vaccination coverage for RFS children is suboptimal, especially for infants who present with recurrent febrile episodes. The initial vaccination delay is partially corrected through specialist follow-up in later years. Coverage according to the supplementary vaccine recommendations for immunosuppressed patients is poor. Key Points ⢠Vaccination coverage for RFS children is suboptimal, especially at 2 years of age which is likely due to the prevalence of early recurrent febrile symptoms. ⢠The initial vaccination delay is partially recovered during later follow-up at an expert rheumatology center. ⢠Specific recommendations are particularly difficult to apply to patients on immunosuppressive therapy.
