Abstract [en]

Background: Clinical improvement during the treatment of rheumatoid arthritis (RA) with the TNFalpha antagonists has been well documented. Our knowledge of uncommon adverse drug reactions (ADRs) with these new drugs is more restricted. Concerns have been raised that these types of drugs could cause an increased frequency of infections, and already existing infections are named as contraindications in the product labels. Methods: in Sweden, it is compulsory for healthcare professionals with permission to prescribe drugs to report suspected ADRs to the regulatory authority, the Medical Product Agency (MPA). At the 6 regional centers that are established in Sweden, a preliminary causality assessment is made and the data is transferred online to a database. Results: Between January 1, 1999, and June 30, 2003, 29 cases of sepsis were reported as suspected adverse effects caused by drugs. Seventeen of these cases concerned TNFa antagonists. The MPA has received 3 reports of septicemia in patients from Northern Sweden treated with the TNFa antagonist etanercept. In submitting these reports, factors that can contribute to Susceptibility and to more fatal Courses of serious infections are taken into consideration. Demographic and pharmaceutical factors as well as risks from predisposing conditions are discussed in connection with the cases in this report. Conclusion: There is a need for more information to physicians to be aware of sepsis as a possible and serious ADR during treatment with TNF antagonists, and that patients with predisposing diseases or those who do not regularly visit their rheumatologist could be at higher risk.
