Impact of Biological Therapies on the Immune Response after Pneumococcal Vaccination in Patients with Autoimmune Inflammatory Diseases.

Patients with different autoimmune inflammatory diseases (AIID) on biological therapy are at risk of pneumococcal disease. Adults with inflammatory arthropathies, connective tissue diseases, psoriasis, or inflammatory bowel disease on biological therapy such as anti-TNFα, rituximab, tocilizumab, abatacept, or anakinra were included in this study. Patients completed a protocol combining the pneumococcal vaccines PCV13 and PPV23. Immune response against pneumococcal serotypes 1, 3, 7F, 14, 19A, and 19F were assessed evaluating functional antibodies by an opsonophagocytosis killing assay (OPKA). In this study, 182 patients with AIID completed the sequential vaccination protocol. Patients on etanercept tended to achieve OPKA titers against a larger number of serotypes than the rest of patients on other biological therapies, while adalimumab was associated to a lower number of serotypes with OPKA titers. Rituximab was not associated with a worse response when compared with the rest of biological agents. Not glucocorticoids, nor synthetic disease-modifying antirheumatic drugs, interfered with the immune response. OPKA titers against serotype 3 which is one of the most prevalent, was obtained in 44% of patients, increasing up to 58% in those on etanercept. Hence, almost 50% of patients on biological therapy achieved functional antibodies after the administration of a complete pneumococcal vaccination protocol.

Evaluation of the immune response to hepatitis B vaccine in patients on biological therapy: results of the RIER cohort study.

To evaluate the response to hepatitis B virus (HBV) vaccine in patients on biological therapy. Adults with autoimmune inflammatory diseases on biological therapy such as anti-TNFα, rituximab, tocilizumab, abatacept, or anakinra were included. Hepatitis B surface antibody (anti-HBs) was measured by ELISA before and after vaccination. Seroconversion was considered when an anti-HBs titer > 10 mIU/mL was achieved. The effect of treatment on the immunoprotective state was studied. The response was compared with that obtained in patients on synthetic disease modifying anti-rheumatic drugs (DMARDs) and healthy controls. A total of 187 patients on biologicals, 48 on synthetic DMARDs, and 49 on healthy controls were analyzed. More than 80% of patients on biologics responded to the vaccine but required more boosters and second vaccine series. Patients who achieved seroconversion were younger than those who did not (47.10 ± 12.99 vs. 53.18 ± 10.54 years, p = 0.012). Being on etanercept or golimumab was associated with seroconversion, while being on rituximab was not. Seroconversion was achieved in 93.75% of patients on synthetic DMARDs and 97.96% of healthy controls. The seroconversion rate in the biologics group was lower than in the synthetic DMARD group (p = 0.043) and tended to be lower than in the healthy group (p = 0.056). In patients on biological therapy, a high rate of HBV vaccine response can be achieved when a complete vaccination schedule is administered. Vaccination while not on biological agents reduces the requirement for boosters and revaccination. Key points: • Patients on biological therapy can achieve high rates of immune response to HBV vaccine when complete vaccination schedules are administered. • However, to achieve such a high seroconversion rate, more boosters and second vaccination series are required. • This supports the proposal already made to provide HBV vaccination to all patients with an autoimmune inflammatory disease after the diagnosis is made and not when the use of a biological treatment is under consideration.

Antibody responses to influenza vaccine in patients on biological therapy: Results of RIER cohort study.

BACKGROUND AND OBJECTIVES: Influenza vaccine is recommended for patients with autoimmune inflammatory rheumatic diseases who receive biological therapy. To evaluate if biological therapy impairs immunization after seasonal influenza vaccine. MATERIAL AND METHODS: Patients with inflammatory arthopathies, psoriasis, inflammatory bowel disease or connective tissue diseases who were receiving or were going to initiate biological therapy were included and vaccinated during 2014-2015 influenza season. ELISA was used to measure influenza antigen A and B antibodies, before and after vaccination. Demographic parameters, diagnosis and kind of treatment were recorded and their influence on the final serological status against influenza was studied. RESULTS: 253 subjects were analyzed. After vaccination, 77% of participants presented detectable antibodies against antigen A and 50.6% of them had detectable antibodies against antigen B. Final seropositivity rate against antigen B antibodies increased from baseline (50.6% vs 43.5%, p<0.001). Anti-TNF drugs were associated with better response and rituximab with the worst (79.2% vs 55.0% for final seropositivity against antigen A, p=0.020). Vaccine response in the rituximab group tended to improve when the interval between the drug administration and the vaccination was at least 12 weeks (seropositivity rate 80.0% in those with the longer interval vs 25.0% in the other group, p=0.054). CONCLUSIONS: Among the patients on biological therapy vaccinated against influenza, anti-TNF therapy was identified as a predictive factor of final seropositivity. Rituximab presented a lower rate of final seropositivity, which could be increased with an accurate administration schedule.

[What do rheumatology residents think of their training? A survey of the National Rheumatology Commission]. / ¿Qué opinan los residentes de reumatología sobre su formación? Una encuesta de la Comisión Nacional de Reumatología.

The National Commission of Rheumatology has developed a satisfaction survey for residents concerning their training period. 37% of the 176 invited to participate answered the survey. 71% said they were satisfied or very satisfied with the influence of the assistance activities during their training. 38% were dissatisfied or very dissatisfied with supervision by staff. 39% were dissatisfied or very dissatisfied with their training in polarized light microscopy. 52% said no regular meetings were structured to monitor their training. 66% said that there had been no effective evaluation of their training. 39% were dissatisfied or very dissatisfied on the tools they were given to publish at their teaching unit. Overall satisfaction on classroom training for residents of Rheumatology is high. There are opportunities for improvement relating to training in certain techniques, monitoring and evaluation of the training period and training in research skills.

Association between anti-cyclic citrullinated peptide antibodies and ischemic heart disease in patients with rheumatoid arthritis.

OBJECTIVE: Patients with rheumatoid arthritis (RA) have an increased risk of cardiovascular disease that may not always be related to the presence of traditional cardiovascular risk factors. The aim of this study was to determine if anti-cyclic citrullinated peptide (anti-CCP) antibodies are associated with cardiovascular disease in patients with RA. METHODS: Anti-CCP antibodies were determined by enzyme-linked immunosorbent assay in the earliest serum sample available from 937 patients with a diagnosis of RA. We studied the relationship between anti-CCP antibodies with traditional cardiovascular risk factors and cardiovascular events. RESULTS: We found positive anti-CCP antibodies (>25 units/ml) in 672 patients (71.7%). There was no association between the anti-CCP antibodies and cardiovascular risk factors such as smoking, hypertension, dyslipidemia, being overweight, or diabetes mellitus. However, patients who had positive anti-CCP antibodies experienced more frequent ischemic heart disease (6.5% versus 2.6%; odds ratio [OR] 2.58, 95% confidence interval [95% CI] 1.17-5.65) and had higher mortality rates (11.2% versus 6.8%; OR 1.72, 95% CI 1.01-2.91). Similar results were obtained when we considered anti-CCP titers 20-fold higher (>500 units/ml). Multivariable analysis showed that ischemic heart disease is independently associated with positive anti-CCP antibodies (OR 2.8, 95% CI 1.19-6.56; P = 0.009). CONCLUSION: Anti-CCP antibodies in patients with RA are independently associated with the development of ischemic heart disease.
