Ten percent of patients recently infected by HIV have contracted a strain of the virus that is resistant to currently used antiretroviral treatments. Moreover, the prevalence of resistance increases significantly at the various stages of management of the disease. Consequently, this is the main obstacle to treatment success. In this context, the guide HIV infection / Antiretroviral resistance -Scientific basis and Recommendations for management, is a highly useful, practical and specialised tool intended to improve management of infected subjects. The book is composed of two parts : the first (chapters 1 to 5) is an updated clarification of the epidemiology of viral resistance, the scientific bases of the mechanism of resistance and management strategy, and review of resistance tests and their interpretation. The second part (colour pages) offers recommendations on the realistic use of tests and management covering all prescribing circumstances. It is specifically intended for the following : doctors involved in the treatment of HIV infection; expert partners in medical decision-making; virologists, biologists and pharmacologists; health care management : departments heads and managers of hospitals or institutions, pharmacists.
