Abstract:
Objective To investigate the prognostic influencing factors and recovery of CD4+ T lymphocytes in elderly HIV/AIDS patients after antiviral therapy by analyzing basic data and clinical follow-up data of elderly HIV/AIDS patients. Methods The clinical data of 3 618 elderly AIDS patients aged ≥50 yeas who received antiretroviral therapy (ART) at HIV ART sites in Liuzhou City from 2005-2015 were collected. The data, including basic information, CD4+ T cell count, WHO clinical stage, infection route and follow-up, were retrospectively analyzed. Kaplan-Meier method was used to compare the differences in patient survival, multivariate Cox regression to analyze the independent influencing factors influencing the risk of death, and to compare the recovery of CD4+ T cell counts during follow-up of patients of different genders. Results During the follow-up period, the 5-year cumulative survival rate up to the observation endpoint was 0.82 (female) and 0.66 (male). Multivariate logistic regression analysis showed that the risk factors affecting the effect of antiviral treatment were age (OR=1.909, 95%CI:1.474-2.464, P<0.001), body mass index (BMI) (OR=0.744, 95%CI: 0.574-0.965, P=0.026), opportunistic infections (OI) (OR=1.223, 95%CI:1.028-1.454, P=0.023), gender (OR=0.692, 95%CI:0.503-0.952, P=0.023) and baseline CD4+ T lymphocytes count (OR=0.563, 95%CI:0.429-0.739, P<0.001). Recovery of CD4+ T lymphocyte counts showed when baseline CD4+ T lymphocyte counts were less than 200 cells/mm3, older women with HIV/AIDS had higher CD4+ T lymphocytes than men at all times of ART treatment (P<0.05). Conclusions Older women have a higher survival rate than older men after five years of antiviral therapy. Age, BMI, gender, OI and baseline CD4+T lymphocyte count may be important indicators that affect the survival of elderly HIV/AIDS patients. Older women showed better recovery of CD4+ T lymphocytes than older men during the 4-year follow-up period after ART.
