Influenza, Pneumococcal and Herpes Zoster Vaccination Rates in Patients with Autoimmune Inflammatory Rheumatic Diseases.

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 The pneumococcal vaccination was outdated in 29.4% of the vaccinated patients.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.

Humoral and cellular response to COVID-19 vaccination in patients with autoimmune inflammatory rheumatic diseases under real-life conditions.

OBJECTIVES: Successful vaccination is key to overcoming the COVID-19 pandemic. Immunosuppressive medication is known to potentially compromise vaccination responses, and expansion of our knowledge on vaccination efficacy in patients with autoimmune inflammatory rheumatic diseases (AIIRD) is therefore of utmost importance. METHODS: We conducted a single-centre observational study and evaluated the efficacy of approved COVID-19 vaccines in 303 adult AIIRD patients. Serum levels of IgG antibodies against the S1 subunit of SARS-CoV-2 spike proteins (anti-S IgG) were measured at least two weeks after vaccination. In a subgroup of patients without humoral response, T-cell responses were determined using an interferon-γ gamma release assay. RESULTS: Overall seropositivity rate was 78.5% and was significantly lower in patients under immunosuppressive therapy (75.7 vs 93.2%, P = 0.009). No difference regarding the vaccination type was observed. Glucocorticoids, mycophenolate-mofetil, TNF inhibitors, tocilizumab, abatacept and rituximab were all associated with non-response after proper vaccination. The risk was highest under RTX therapy (OR 0.004, 95% CI 0.001, 0.023, P < 0.0001). A strong negative correlation was observed between time since vaccination with an mRNA vaccine and anti-S antibody levels (r=-0.6149, P < 0.0001). In patients without humoral response, a T-cell response was found in 50%. CONCLUSIONS: COVID-19 vaccination in patients with AIIRD is effective using any approved vaccine. Humoral response might be impaired depending on the individual immunosuppressive medication. The risk of non-response is highest under rituximab therapy. Anti-S IgG antibody levels wane over time after mRNA vaccination. Importantly, 50% of humoral non-responders showed a T-cellular response, suggesting T-cell-mediated protection to a certain extent.

COVID-19 Vaccination Coverage in Patients with Rheumatic Diseases in a German Outpatient Clinic: An Observational Study.

BACKGROUND: In the second year of the COVID-19 pandemic, highly effective and safe vaccines became available. Since patients with rheumatic diseases show increased susceptibility to infections and typical medications raise the risk of severe COVID-19, high vaccination coverage is of significant importance to these patients. METHODS: Consecutive patients with different rheumatic diseases were asked for their vaccination status regarding COVID-19, influenza and Streptococcus pneumoniae during their routine consultations. Any reported vaccination was validated with their personal vaccination card and/or by reviewing the CovPass smartphone app. Reasons for not having a COVID-19 vaccination were documented. RESULTS: A total of 201 patients (mean age 62.3 ± 14.1 years) were included, the majority of them (44.3%) with rheumatoid arthritis, followed by spondyloarthritis (27.4%) and connective tissue diseases (21.4%). Vaccination coverage for SARS-CoV-2 was 80.1%; 85.6% got at least the first vaccination shot. Both valid influenza and pneumococcus coverage were associated with a higher probability of SARS-CoV-2 vaccination (odds ratio (OR) 6.243, 95% confidence interval (CI) 2.637-14.783, p < 0.0001 and OR 6.372, 95% CI 2.105-19.282, p = 0.0003, respectively). The main reason for a missing SARS-CoV-2 vaccination (70%) was being sceptical about the vaccine itself (i.e., the subjective impression that the vaccine was not properly tested and fear of unwanted side effects). CONCLUSIONS: Vaccination coverage against SARS-CoV-2 is high in patients with rheumatic diseases. Nevertheless, there are unmet needs regarding vaccination education to further increase vaccination rates.

[Thoracolumbar back pain as the leading symptom of a marked COVID-19 pneumonia]. / Thorakolumbaler Rückenschmerz als führendes Symptom einer ausgeprägten COVID-19-Pneumonie.

HISTORY: A 49-year-old male patient visited the surgical outpatient clinic with new onset low back pain. The pain was increasing for nine days and he did not have any signs of a respiratory infection, in particular neither fever nor cough. INVESTIGATIONS: During the further examination and unclothing, mild dyspnea was apparent. According to the patient, the dyspnea was also progressive in the last days but would not affect everyday life. Furthermore, the patient reported a significant and unintended weight loss. Outpatient chest X-ray revealed bilateral, peripheral, fine-speckled infiltrates that became increasingly confluent. Polymerase chain reaction analysis of the nasopharyngeal swab was positive for SARS-CoV-2 (wild type). TREATMENT AND COURSE: Due to progressive dyspnea, the patient was referred to inpatient treatment within the day, where he rapidly developed severe acute respiratory failure. To provide respiratory support, a combined intermittent non-invasive ventilation and nasal high flow-therapy was started. Moreover, a probatory antiviral therapy with remdesivir was initiated. Since a bacterial superinfection was suspected, additional antibiotic therapy was ordered. After 13 days of inpatient treatment, the patient was discharged. The low back pain receded completely during inpatient treatment without any specific therapy. CONCLUSIONS: Low back pain can be a symptom of COVID-19. In our case report, it was the only complain that led to the outpatient consultation. Even though back pain is a very common symptom in everyday practice, one should keep unusual causes in mind.
