Abstract
BACKGROUND: Vaccination rates are known to be low in patients with autoimmune inflammatory rheumatic diseases (AIIRD). We therefore aimed to determine current vaccination rates against influenza, Streptococcus pneumoniae and herpes zoster in a cohort of patients with AIIRD in Germany. METHODS: Consecutive adult patients with an AIIRD were recruited from our outpatient clinic during their regular consultations. The individual vaccination status regarding influenza, Streptococcus pneumoniae and herpes zoster was obtained by reviewing the vaccination documents. RESULTS: A total of 222 AIIRD patients (mean age 62.9 ± 13.9 years) were included. In total, 68.5% were vaccinated against influenza, 34.7% against Streptococcus pneumoniae and 13.1% against herpes zoster (HZ). The pneumococcal vaccination was outdated in 29.4% of the vaccinated patients. Vaccination rates were significantly higher in patients ≥60 years old (odds ratio (OR) 2.167, 95% confidence interval (CI) 1.213-3.870, p = 0.008 for influenza, OR 4.639, 95% CI 2.555-8.422, p < 0.0001 for pneumococcal and OR 6.059, 95% CI 1.772-20.712, p = 0.001 for HZ vaccination). Ages > 60 years, female sex, glucocorticoid use and influenza vaccination were all independently associated with a pneumococcal vaccination. Regarding influenza vaccination, only a positive pneumococcal vaccination history remained independently associated. In patients with HZ vaccination, glucocorticoid use and a preceding pneumococcal vaccination were independently associated with HZ protection. CONCLUSIONS: The frequencies of vaccinations against influenza, Streptococcus pneumoniae and HZ have increased during recent years. While this can be partly explained by continuous efforts in patient education during the outpatient visits, the COVID-19 pandemic might also have contributed. Nevertheless, the persistently high incidence and mortality of these preventable diseases in patients with AIIRDs mandates further efforts to increase vaccination coverage, particularly in SLE patients.
