with AIDS. In parallel to the progress in HIV treatment in general, new diagnostic and therapeutic possibilities have recently been developed for various HIV-associated pulmonary complica- tions. This issue of the ERS Monograph summarises the current practices and new developments in the prevention, diagnosis and treatment of HIV-related pulmonary complications. I want to congratulate Charles Feldman, Eva Polverino and Julio Ramirez on the tremendous work they have done in compiling this excellent Monograph. This book should be of interest to everybody involved in HIV management worldwide. I hope it will stimulate joint research for a better understanding of and more successful therapy for HIV-related pulmonary infectious diseases. References 1. Piot P, Quinn TC.
