We investigate the associations of three established plasma biomarkers in the context of HIV and treatment-related variables including a comprehensive cardiovascular disease risk assessment, within a large ambulatory HIV cohort. Patients were recruited in 2010 to form the Royal Perth Hospital HIV/CVD risk cohort. Plasma sCD14, sCD163 and CXCL10 levels were measured in 475 consecutive patients with documented CVD risk (age, ethnicity, gender, smoking, blood pressure, BMI, fasting metabolic profile) and HIV treatment history including immunological/virological outcomes. The biomarkers assessed showed distinct associations with virological response: CXCL10 strongly correlated with HIV-1 RNA (p<0.001), sCD163 was significantly reduced among 'aviraemic' patients only (p = 0.02), while sCD14 was unaffected by virological status under 10,000 copies/mL (p>0.2). Associations between higher sCD163 and protease inhibitor therapy (p = 0.05) and lower sCD14 with integrase inhibitor therapy (p = 0.02) were observed. Levels of sCD163 were also associated with CVD risk factors (age, ethnicity, HDL, BMI), with a favourable influence of Framingham score <10% (p = 0.04). Soluble CD14 levels were higher among smokers (p = 0.002), with no effect of other CVD risk factors, except age (p = 0.045). Our findings confirm CXCL10, sCD163 and sCD14 have distinct associations with different aspects of HIV infection and treatment. Levels of CXCL10 correlated with routinely monitored variables, sCD163 levels reflect a deeper level of virological suppression and influence of CVD risk factors, while sCD14 levels were not associated with routinely monitored variables, with evidence of specific effects of smoking and integrase inhibitor therapy warranting further investigation.
在一个大型门诊HIV队列中,我们研究了三种已确立的血浆生物标志物与HIV及治疗相关变量之间的关联,这些变量包括全面的心血管疾病风险评估。患者于2010年被招募,组成了皇家珀斯医院HIV/CVD风险队列。对475名有记录的CVD风险(年龄、种族、性别、吸烟、血压、BMI、空腹代谢状况)及HIV治疗史(包括免疫/病毒学结果)的连续患者测量了血浆sCD14、sCD163和CXCL10水平。评估的生物标志物显示出与病毒学反应的不同关联:CXCL10与HIV-1 RNA强烈相关(p<0.001),仅在“病毒血症阴性”患者中sCD163显著降低(p = 0.02),而当病毒载量低于10,000拷贝/mL时,sCD14不受病毒学状态影响(p>0.2)。观察到较高的sCD163与蛋白酶抑制剂治疗之间的关联(p = 0.05)以及较低的sCD14与整合酶抑制剂治疗之间的关联(p = 0.02)。sCD163水平也与CVD风险因素(年龄、种族、高密度脂蛋白、BMI)相关,弗雷明汉评分<10%有有利影响(p = 0.04)。吸烟者的可溶性CD14水平较高(p = 0.002),除年龄外(p = 0.045),其他CVD风险因素无影响。我们的研究结果证实,CXCL10、sCD163和sCD14与HIV感染和治疗的不同方面有不同关联。CXCL10水平与常规监测变量相关,sCD163水平反映了更深层次的病毒学抑制及CVD风险因素的影响,而sCD14水平与常规监测变量无关,吸烟和整合酶抑制剂治疗的特定影响证据值得进一步研究。
