More resistance mutations were detected in the provirus in CD4 cells than in the virus in plasma and these mutations persisted for at least 1 year of follow-up with or without therapy, but the overall pattern of resistance was fairly similar in plasma and cells. HIV-1 proviral DNA would in our hands be most useful for making decisions, when changing therapy,

“The PubMed database was searched under the following headings: HIV or AIDS and lung or pneumonia or pneumonitis and/or Pneumocystis carinii, Pneumocystis jirovecii, Pneumocystis pneumonia, PCP, Cryptococcus neoformans, cryptococci, Cryptococcus, Aspergillus, aspergillosis, CMV, influenza A virus, influenza B virus, parainfluenza virus, respiratory syncytial virus, bacteria and vaccination. The immune dysregulation

associated with HIV results in an increased incidence of respiratory infection at all CD4 T-cell counts. Early reports of the dramatic increased risk of Pneumocystis pneumonia (PCP) in advanced HIV disease have tended to overshadow the finding that other respiratory pathogens are also more common in HIV disease (Table 3.1). The widespread use of prophylaxis against opportunistic infections together with HAART has reduced the risk of life-threatening infection, selleck compound though it has not returned to the background levels present

in HIV-sero negative populations [1]. Mycobacterial Olopatadine disease is not discussed in this section as Mycobacterium tuberculosis is the focus of separate guidelines [2]. Pulmonary symptoms may arise from infection with a wide variety of organisms although PCP and bacterial pneumonia predominate. A simple patient risk assessment allows the clinician to determine the likelihood that other opportunistic infections (OI) are the cause of severe respiratory disease and that further pathogens may need to be considered. Relevant factors include: (1) patient use of effective OI prophylaxis or HAART; (2) recent discharge from hospital or current hospital admission >5 days (nosocomial infections); (3) country/place of residence and travel history; (4) history of active injecting drug use, since these individuals are at increased risk of bacterial pneumonia and TB; (5) level of host immunity; (6) neutropenia; and (7) use of prolonged courses of immune modulators (e.g. corticosteroids). Treatment is often started prior to laboratory confirmation of diagnosis. The intensity with which investigation is undertaken is usually determined by the patient risk assessment, the severity of the illness and the resources available locally.
