Characteristics and associated factors of blood lipid trajectories among HIV-infected patients receiving antiretroviral therapy

Abstract

Objective: To examine characteristics and risk factors of the blood lipid trajectories among HIV-infected patients treated with antiviral therapy (ART). Methods: Based on the retrospective cohort study design, sociodemographic characteristics and baseline laboratory indicators of HIV-infected patients receiving ART from January 2004 to April 2021 in Taizhou, Zhejiang province. The blood lipid trajectories of the subjects was described and classified using the latent class mixed model (LCMM). Multivariate logistic regression was used to determine the risk factors of blood lipid trajectories. The data were analysized by R 3.5.0. software with lcmm package. Results: Among 2 079 HIV-infected patients, the median age (Q1, Q3) was 31 (43, 55) years, and the majority were being male (78.1%, 1 623/2 079) and married (58.7%, 1 221/2 079). BMI ≥24.0 kg/m2 accounted for 18.9% (393/2 079). Heterosexual transmission accounted for 67.7% (1 407/2 079). Three different blood lipid trajectories were classified: inverted U-shaped (2.3%, 48/2 079), progressive (31.3%, 650/2 079), and general trajectory (U-shaped) (66.4%, 1 381/2 079). The inverted U-shaped and progressive trajectory are identified as dangerous trajectories (33.6%). Multivariate logistic regression analysis indicated that compared with 3TC-TDF-EFV antiviral treatment regimen, baseline TC level <5.2 mmol/L, baseline TG level <1.7 mmol/L, BMI 18.5-23.9 kg/m2, baseline CD4+T lymphocytes (CD4) counts <200 cells/μl, antiviral treatment time <5 years,those who had been using 3TC-AZT-EFV antiviral therapy regimen (aOR=1.99,95%CI:1.44-2.77) and those who switched to LPV/r antiviral therapy regimen (aOR=3.17, 95%CI: 2.00-5.01), baseline TC levels were 5.2-6.1 mmol/L (aOR=2.55, 95%CI: 1.92-3.39) and ≥6.2 mmol/L (aOR=5.89,95%CI:3.76-9.25), and baseline TG levels were 1.7-2.2 mmol/L (aOR=2.00, 95%CI: 1.53-2.62) and ≥2.3 mmol/L (aOR=6.51,95%CI:4.97-8.54), respectively, BMI ≥24.0 kg/m2 (aOR=1.44, 95%CI: 1.11-1.88) were more likely to show the dangerous trajectories. BMI <18.5 kg/m2 (aOR=0.55, 95%CI: 0.35-0.86), baseline CD4 counts level was 200-349 cells/μl (aOR=0.67, 95%CI: 0.52-0.87) and baseline CD4 ≥350 cells/μl (aOR=0.71, 95%CI: 0.54-0.94). The duration of antiviral therapy was 5-9 years (aOR=0.74, 95%CI: 0.56-0.99), and ≥10 years (aOR=0.53, 95%CI: 0.22-0.67) were less likely to show the dangerous trajectories. Conclusions: HIV-infected patients showed a dangerous trajectory of blood lipids after ART, which was significantly associated with the use of specific antiviral drugs such as AZT and LPV/r, treatment duration, baseline CD4, TC, TG levels and BMI. It is recommended to strengthen blood lipid monitoring and targeted intervention measure when HIV infected persons start antiviral treatment.
