Infective endocarditis has continuously evolved since its first clinical description by William Osler in the late 19th century. The epidemiological and microbiological profile of the disease has changed as the result of the progress of the medical care and demographic mutation in industrialized countries. ⋯ During the past decade, the recommendations on antibiotic prophylaxis against infective endocarditis have changed dramatically. Guidelines on management of infective endocarditis and state-of-the-art articles have been published recently and this work aims to outline current recommendations about this evolving disease.

Hepatitis B virus (HBV) infection is frequent with about 400 million individuals infected worldwide. Extrahepatic manifestations may be observed in up to 20% of patients infected with HBV, in both acute and chronic infections. ⋯ Besides manifestations related to HBV, patients presenting with primary autoimmune disorders and infected with HBV may exhibit reactivation of hepatitis B during immunosuppressive therapy that may be life-threatening. This article focuses on autoimmune manifestations related to HBV and its treatment, and on the risk of reactivation of HBV hepatitis in patients with primary autoimmune disorders treated with immunosuppressive agents.
