Preventive influenza vaccination for patients with rheumatoid arthritis. A need for an international campaign

High dose trivalent influenza vaccine compared to standard dose vaccine in patients with rheumatoid arthritis receiving TNF-alpha inhibitor therapy and healthy controls: Results of the DMID 10-0076 randomized clinical trial

INTRODUCTION

Subjects with rheumatoid arthritis (RA) receiving tumor necrosis factor-inhibiting (TNFi) therapies are at risk for severe influenza, and may respond less well to influenza vaccine. We examined the safety and immunogenicity of high dose influenza vaccine (HD) compared to standard dose vaccine (SD) in participants with RA receiving stable TNFi.

METHODS

A randomized, double-blinded, Phase II study was conducted in adults with RA receiving TNFi, and healthy, gender and age-matched control subjects. Participants were immunized with HD (Sanofi Pasteur Fluzone High Dose [60 mcg × 3 strains]) or SD (Sanofi Pasteur Fluzone® [15 mcg × 3 strains]) intramuscularly (IM). A self-administered memory aid recorded temperature and systemic and local adverse events (AEs) for 8 days, and safety was evaluated and serum obtained to measure HAI activity on days 7, 21 and 180 days following vaccination.

RESULTS

A greater proportion of RA subjects who received HD seroconverted at day 21 compared to SD, although this was not statistically significant. GMT antibody responses in RA subjects who received HD compared to SD were greater for all strains on day 21, and this was significant for H1N1. Seroconversion rates and GMT values were not different between RA subjects and control subjects. There were no safety concerns for HD or SD in RA subjects, and RA-related symptoms did not differ between SD and HD recipients by a RA-symptom questionnaire (RAPID 3).

CONCLUSIONS

TNF-inhibitor therapy in people with RA did not appear to influence the immunogenicity of either SD or HD. Influenza seroconversion and GMT values were higher among RA subjects receiving HD compared to SD; however, differences were small and a larger study is needed to validate these findings. Given the apparent risk of increased influenza-related morbidity and mortality among immune compromised subjects, the higher GMT values generated by HD may be beneficial.

A survey to evaluate the implementation of vaccine recommendations among rheumatologists practicing in Greece

Objectives

We sought to document the knowledge, perceptions and attitudes toward vaccinations among rheumatologists practicing in Greece.

Methods

Rheumatologists practicing in Greece in 2015 were surveyed by questionnaire during the Postgraduate Course of the Greek Rheumatology Society. Statistical analysis was carried out using SPSS software.

Results

One hundred and ten practicing rheumatologists in Greece were surveyed. Response rate was 63%. The majority of responders (82%) inquire patients about vaccination status during rheumatology medical history and most of them specifically advise patients for vaccination uptake (91%). Correct identification of all vaccine types was made by 11% of rheumatologists that took the survey. Ninety-three percent of responders were aware that influenza vaccine should be administered annually, and 94% acknowledged the need for pneumococcal vaccination. Some were not concerned about reduced immunogenicity in patients receiving treatment with methotrexate/TNF inhibitors and rituximab/abatacept (17% and 7%, respectively). A notable percentage overlook that live vaccines are contraindicated during treatment with TNF inhibitors (17%), conventional synthetic DMARDs (61%), or corticosteroids (30%).

Conclusions

According to our results, the majority of Greek rheumatologists have implemented a vaccine strategy in their everyday practice. Still, there are several misconceptions that need to be addressed. A significant percentage cannot properly distinguish between inactivated and live vaccines, and many are not knowledgeable of the potential effect of specific DMARDs on the immunogenicity and safety of vaccination.

Vaccinations in adults with chronic inflammatory joint disease: Immunization schedule and recommendations for patients taking synthetic or biological disease-modifying antirheumatic drugs

The risk of infection associated with autoimmune diseases is further increased by the use of biotherapies. Recommendations to minimize this risk include administering the full complement of vaccines on the standard immunization schedule, as well as the pneumococcal and influenza vaccines. Adults with chronic inflammatory joint disease (IJD) may receive a 13-valent pneumococcal conjugate vaccine, as well as a live attenuated vaccine against recurrent herpes zoster, recently licensed by European regulatory authorities. Live attenuated vaccines can be given only after an interval without immunosuppressant and/or glucocorticoid therapy. The effectiveness of vaccines, as assessed based on titers of protective antibodies, varies across vaccine types and disease-modifying antirheumatic drugs (DMARDs). Thus, methotrexate and rituximab are usually associated with decreased vaccine responses. The risks associated with vaccines are often considerably exaggerated by the media, which serve lobbies opposed to immunizations and make some patients reluctant to accept immunizations. Increasing immunization coverage may diminish the risk of treatment-related infections. A physician visit dedicated specifically to detecting comorbidities in patients with chronic IJD may result in improved immunization coverage. In this review, we discuss immunizations for adults with chronic IJD based on the treatments used, as well as immunization coverage. Many questions remain unanswered and warrant investigation by studies coordinated by the French networks IREIVAC (Innovative clinical research network in vaccinology) and IMIDIATE (Immune-Mediated Inflammatory Disease Alliance for Translational and Clinical Research).

[Vaccination in adult patients with chronic inflammatory rheumatic diseases]

Patients with chronic inflammatory rheumatic diseases often have an intrinsic and therapy associated increased susceptibility to infections which substantially contributes to morbidity and mortality of the patients. A large proportion of these infections are preventable by vaccination. For this reason in 2005 the standing vaccination committee (STIKO) recommended for patients with immunosuppression vaccination against pneumococcus, influenza, Haemophilus influenza b and meningococcus in addition to standard vaccinations, independent of age. Every patient should therefore be informed about a possible increase in susceptibility to infections and the recommended prevention by vaccination before implementation of immunosuppressive therapy.

The delivery of evidence-based preventive care for older Americans with arthritis

INTRODUCTION

Previous research suggests patients with rheumatoid arthritis (RA) may receive suboptimal care with respect to preventive tests and services. We evaluated the proportion of older Americans with RA, psoriatic arthritis (PsA), and osteoarthritis (OA) receiving these services and the specialty of the providers delivering this care.

METHODS

Using data from 1999 to 2006 from the Medicare Chronic Conditions Warehouse, we identified persons age >/= 65 in the national 5% sample. Over the required five-year observation period, we identified tests and services recommended for older adults and the associated healthcare provider. Services of interest included dual energy x-ray absorptiometry (DXA), influenza and pneumococcal vaccination, hyperlipidemia lab testing, mammography and colonoscopy.

RESULTS

After accounting for the sampling fraction, we identified 141,140 RA, 6,300 PsA, and 770,520 OA patients eligible for analysis. Over five years, a majority of RA, PsA, and OA patients were tested for hyperlipidemia (84%, 89% and 87% respectively) and received DXA (69%, 75%, and 52%). Only approximately one-third of arthritis patients received pneumococcal vaccination; 19% to 22% received influenza vaccination each year. Approximately 20% to 35% of arthritis patients never underwent mammography and colonoscopy over five years. Concomitant care from both a rheumatologist and a primary care physician was significantly associated with a greater likelihood of receiving almost all preventive tests and services.

CONCLUSIONS

Among older Americans on Medicare, the absolute proportion of persons with arthritis receiving various recommended preventive services and screening tests was substantially less than 100%. Improved co-management between primary care and arthritis physicians may in part improve the delivery of preventive care for arthritis patients, but novel systematic interventions in this area are needed.
