New therapies have changed the way doctors care for people with HIV, and have shifted treatment strategies to the outpatient setting. BUCKLEY: HIV INFECTION IN PRIMARY CARE is designed to give primary care providers concise and practical information on the diagnosis and management of patients infected with HIV. Part I, Early Infection, focuses on evaluating and testing patients at risk for HIV infection. These chapters will discuss how to monitor patients' immune system and when and how to treat them during this first stage, and keep them well for as long as possible. Part II focuses on the diagnosis and treatment of opportunistic infections and other manifestations of progressive infection. Part III discusses some special aspects of HIV infection, and the differential diagnosis of common syndromes in full blown AIDS.
