BACKGROUND: The long-term consequences of wasting among HIV-infected persons are not known.
DESIGN: HIV-infected men surviving ≥2 years based on Kaplan-Meier analysis after a clinical diagnosis or weight trajectory consistent with wasting and with available physical function assessment data [grip strength, gait speed, and quality of life (QoL)] were matched to HIV-infected and uninfected men without wasting.
METHODS: Matching criteria at the functional assessment included age, calendar year, and CD4 T-cell count and plasma HIV-1 RNA (HIV-infected only). Multivariable linear regression analyses adjusted for age, cohort, race, hepatitis C status, and number of comorbid illnesses were used to assess the impact of wasting on subsequent physical function.
RESULTS: Among 85 HIV-infected men surviving ≥2 years after wasting, we evaluated physical function outcomes compared with 249 HIV-infected and 338 HIV-uninfected men with no historical wasting. In multivariable regression models, HIV-infected men with prior wasting had lower grip strength and poorer physical QoL than HIV-infected men with no wasting (P ≤ 0.03), and poorer physical QoL, but higher mental QoL than HIV-uninfected men (P ≤ 0.05). When controlling for measures of immune suppression (nadir CD4 T-cell count/AIDS, the association between wasting and physical QoL was markedly attenuated, whereas there was minimal impact on the association between wasting and grip strength.
CONCLUSIONS: HIV-infected wasting survivors had weaker grip strength compared with HIV-infected persons without wasting; immune suppression was associated only with physical QoL. HIV-infected survivors of wasting may represent a population of adults at increased risk for physical function decline.
