Pulmonary complications of HIV infection.
The AIDS epidemic has had a devastating global impact in the last two decades; although prevalence rates are low in Asia and the Pacific, their enormous population is associated with an estimated 1 million people infected with HIV in 2006 alone. Survival from what had been a uniformly fatal illness has improved markedly with combination antiretroviral therapy and restoration of the immune system, but these treatments are expensive and difficult to distribute to the millions who need them around the world. In addition, millions more do not know they are infected with HIV until they develop an opportunistic infection. The lungs are the most frequent sites of these infections, and in different geographic regions, tuberculosis, bacterial pneumonia and Pneumocystis jiroveci are the dominant pathogens. The incidences of lung cancer and HIV-associated pulmonary arterial hypertension are also increasing in patients with HIV infection, and with the use of antiretrovirals, inflammatory disorders associated with immune restoration are being recognized.
