[Vaccination against influenza in patients with rheumatoid arthritis: clinical and antibody response].
The question whether influenza vaccine could lead to a clinical flare in patients with rheumatoid arthritis (RA), and whether it could induce an effectively protective antibody response to the infection is still much debated. Based on these data, we have performed an open study in 40 patients with RA. Patients were divided into two groups according to their disease activity (those with RA in remission and those with active RA, respectively), and their clinical and serum antibody response was assessed following the vaccine administration in the 1991-92 winter seasons. A group of age and sex matched, healthy controls were also vaccinated. Our results suggest that immunization against influenza does not modify the clinical picture of RA, even though some differences between the two groups mentioned above were noticed. In addition, side-effects or adverse reactions occurred with similar frequency in patients with RA and in the controls; as to the antibody response in patients with RA, in the majority of cases the immune response proved adequate to provide significant protection from the infection.
