H1N1 virus and vaccination among rheumatology patients, especially those on DMARDS.

With the influenza season facing us much concern exists among rheumatologist and rheumatology patients regarding the impact of the seasonal influenza virus. Unfortunately this year we also face the additional challenge and worry of the H1N1 virus, first described in April 2009, among rheumatology patients, especially those on Disease-Modifying Anti-Rheumatic Drugs (DMARDs). Traditionally Rheumatologists have become structured in dealing with seasonal influenza vaccination, however 2009 saw many rheumatologists struggling to advise patient regarding the H1N1 virus and associated vaccination. Thankfully the American College of Rheumatology 1 have issued clear guidelines (September 2009), along with the Irish Society for Rheumatology (October 2009) 2 on how to advise and manage patients regarding the H1N1 virus and vaccination.
