Abstract:
Objective:To explore the dynamic change of platelet count and related factors in HIV-infected patients with access to antiretroviral therapy (ART) in Dehong Dai and Jingpo autonomous prefecture of Yunnan province.Methods:A longitudinal analysis was used to analyze the dynamic change of platelet count in HIV-infected patients with access to ART. Linear mixed model (LMM) was used to analyze factors associated with the dynamic change of platelet count. Stratified analysis and sensitivity analysis were also conducted.Results:A total of 761 HIV-infected patients were recruited and 608 cases had at least one follow-up record (80.0%,608/761). 374, 555 and 233 cases were investigated in follow-up visits at month 6, 12 and 24, respectively. The mean platelet count and the proportion of higher platelet count (>300×10 9/L) were significantly higher in women than in men at both baseline survey and each follow-up visit ( P<0.05). Among patients with no obvious liver fibrosis, the mean platelet count was significantly higher in women than in men at baseline survey and each follow-up visit; while in the patients with liver fibrosis, the mean baseline platelet count was still significantly higher in women than in men, but the difference had no significance at follow-up visits. Results of LMM revealed that follow-up platelet count was positively correlated with gender ( β=5.90, 95% CI: 1.09-10.70, P=0.016), baseline platelet count ( β=0.82, 95% CI: 0.79-0.86, P<0.001) and time ( β=1.76, 95% CI: 1.52-2.01, P<0.001). Sensitivity analysis among 220 cases who had both 12- and 24-month follow-up visits further confirmed that follow-up platelets count was still positively associated with gender ( β=10.50, 95% CI: 2.24-18.74, P=0.013), baseline platelet count ( β=0.71, 95% CI: 0.65-0.77, P<0.001) and time ( β=1.60, 95% CI: 1.20-1.99, P<0.001) but negatively associated with age ( β=-0.42, 95% CI: -0.78--0.06, P=0.021). Conclusions:The platelet count of HIV-infected patients gradually increased after ART. The mean platelet count was consistently higher in women than in men. Attention should be paid to the gender specific difference in platelet count in HIV-infected patients and timely intervention should be given to reduce the morbidity and mortality of platelet-related diseases.
