Influencing factors of antiviral treatment efficacy in patients with acquired immunodeficiency syndrome / 中华传染病杂志

ABSTRACT

Objective:To explore the factors affecting the antiviral treatment efficacy of acquired immunodeficiency syndrome (AIDS) patients.Methods:A total of 107 patients diagnosed with human immunodeficiency virus (HIV) infection in the clinic of Beihai People′s Hospital from January 2016 to June 2018 were selected.The patients were divided into two groups according to whether they voluntarily accepted traditional Chinese medicine treatment, including treatment group who received highly active anti-retroviral therapy (HAART) and traditional Chinese medicine prescription of Ping Gan Jie Du (42 cases), and control group who were only treated with HAART (65 cases). The virological and immunological responses were compared between the two groups at 48 weeks of treatment. The interleukin-28B (IL-28B) rs12979860 genotypes were measured by using the direct sequencing of polymerase chain reaction products. Logistic regression was used to analyze the influencing factors of antiviral efficacy in AIDS patients.Comparison between groups was performed by independent sample t test、matched sample t test or chi-square test. Results:At week 48 of treatment, 41 (97.62%) of the 42 patients in the HAART plus Ping Gan Jie Du group obtained virological response, while 58 (89.23%) of the 65 patients in the HAART group alone acquired virological response, which was not significantly different ( χ2=0.100, P>0.05). The numbers of CD4 + T lymphocytes increased at week 48 of treatment in the HAART plus Ping Gan Jie Du group and HAART group were (244.32±101.83)/μL and (211.56±112.50)/μL, respectively. The was no statistically significant difference ( t=1.522, P>0.05). Among the 92 patients with IL-28B CC genotype, 88 (95.65%) acquired virological response, while 11 of the 15 patients with non-IL-28B CC genotype acquired virological response, which was not significantly different ( χ2=0.394, P>0.05). And CD4 + T lymphocytes in patients with IL-28B CC genotype increased ((229.72±101.17)/μL), which was higher than that without IL-28B CC genotype ((173.40±89.64)/μL), with statistically significant difference ( t=2.028, P=0.045). Multivariate logistic regression analysis showed that baseline CD4 + T lymphocyte count≤200/μL, IL-28B CC genotype, and treatment plan including protease inhibitor were helpful to improve the antiviral efficacy. Conclusion:Baseline CD4 + T lymphocyte count ≤200/μL, IL-28B CC genotype, and protease inhibitor in HAART regimen are the influencing factors of antiviral efficacy in AIDS patients.
