Abstract
In the early years of the AIDS epidemic, HIV infection was associated with visible signs and symptoms, adding to the stigma associated with the disease. Physical manifestations associated with HIV infection included muscle wasting, lymphadenopathy, Kaposi's sarcoma, candidiasis, molluscum contagiosum, and hairy leukoplakia. With the advent of antiretroviral therapy, particularly the introduction of highly active antiretroviral therapy in 1996, many of these outward manifestations of the disease became rare. Ironically, however, the treatments used to control HIV infection (and its visible markers) have themselves been associated with appearance-related side effects. Patients may develop changes in fat distribution, rashes, skin hyperpigmentation, or paronychia. These effects not only have cosmetic and psychological consequences but also may decrease adherence to therapy, potentially causing regimen failure and drug resistance. Newer antiretroviral agents offer improved potency, more convenient dosing, and more treatment options with the potential for fewer side effects and drug interactions, which should foster optimal adherence by the patient. However, these newer drugs are also associated with appearance-related side effects, which must be considered in the selection of treatment regimens. This paper reviews the appearance-related side effects associated with classes of antiretroviral drugs as well as individual agents, including the newer antiretrovirals.
