摘要

目的:探究男性尖锐湿疣(condyloma acuminatum,CA)合并人类免疫缺陷病毒(human immunodeficiency virus,HIV)患者全血辅助性T淋巴细胞亚群与CA组织Ki-67、p16、血管内皮生长因子(vascular endothelial growth factor,VEGF)、CD34表达的相关性及其临床意义。方法:回顾分析2018年10月至2020年10月85例男性CA患者的临床病理资料。根据是否合并HIV感染将其分为CA组(36例)与CA合并HIV组(49例)。分析两组HPV的感染情况和全血辅助性T淋巴细胞亚群(淋巴细胞、T淋巴细胞、CD4+T淋巴细胞及CD8+T淋巴细胞)计数的差异;HE染色观察CA组织的病理形态特点;免疫组织化学染色检测CA组织Ki-67、p16、VEGF、CD34的表达,分析两组Ki-67、p16、VEGF、CD34的表达差异;采用Spearman秩相关分析研究全血辅助性T淋巴细胞亚群与HPV感染、Ki-67、p16、VEGF、CD34的相关性;应用logistic逐步回归分析探讨CA合并HIV的影响因素。结果:CA合并HIV组CD8+T淋巴细胞计数、Ki-67增殖指数、p16表达、VEGF表达、CD34微血管密度均高于CA组(分别P<0.001、P=0.009、P<0.001、P<0.001、P<0.001),CA合并HIV组CD4+T淋巴细胞计数低于CA组(P<0.001),两组间HPV感染、淋巴细胞计数、T淋巴细胞计数的差异均无统计学意义(分别P=0.135、P=0.862、P=0.876)。淋巴细胞计数和Ki-67增殖指数呈正相关(rs=0.257,P=0.018),CD4+T淋巴细胞计数与p16表达、VEGF表达呈负相关(rs=−0.232,P=0.033;rs=−0.252,P=0.020),CD8+T淋巴细胞计数与HPV感染、Ki-67增殖指数、p16表达、VEGF表达呈正相关(rs=0.220,P=0.043;rs=0.346,P=0.001;rs=0.350,P=0.001和rs=0.363,P=0.001),其他指标间不存在相关性。Logistic回归分析显示CD4+T淋巴细胞计数、p16表达、VEGF表达、CD34微血管密度是CA合并HIV的独立危险因素。结论:在男性CA合并HIV患者中,血清CD4+T淋巴细胞计数降低,CA组织细胞增殖活跃及血管生成增多,可作为CA诊断及预后不良的重要指标。

Abstract

Objective: To explore the correlation and clinical significance of whole blood lymphocyte subsets and the expression of Ki-67, p16, VEGF and CD34 in male condyloma acuminatum (CA) patients with human immunodeficiency virus (HIV). Methods: The clinicopathological data of 85 male patients with CA from October 2018 to October 2020 were retrospectively analyzed. They were divided into a CA group (36 cases) and a CA combined with HIV group (49 cases) according to whether they were infected with HIV. The infection of HPV and the count of helper T lymphocyte subsets (lymphocyte, T lymphocyte, CD4+T lymphocyte and CD8+T lymphocyte) in the whole blood of the 2 groups were analyzed; the pathological features of CA tissues were observed by HE staining; the expression of Ki-67, p16, VEGF and CD34 in CA tissues were detected by immunohistochemical staining; the expression differences of Ki-67, p16, VEGF and CD34 between the 2 groups were analyzed. Spearman rank-correlation analysis was used to analyze the correlation between the whole blood helper T lymphocyte subsets and HPV infection, Ki-67, p16, VEGF, CD34; logistic stepwise regression analysis was used to explore the influencing factors of CA complicated with HIV. Results: The CD8+T lymphocyte count, Ki-67 proliferation index, p16 expression, VEGF expression and CD34 microvessel density of the CA combined with HIV were higher than those of the CA group (P<0.001, P=0.009, P<0.001, P<0.001, P<0.001, respectively). The CD4+T lymphocyte count of the CA combined with HIV was lower than that of the CA group (P<0.001). There was no significant difference in HPV infection, lymphocyte count and T lymphocyte count between the 2 groups (P=0.135, 0.862 and 0.876). There was a positive correlation between lymphocyte count and Ki-67 proliferation index (rs=0.257, P=0.018), a negative correlation between CD4+T lymphocyte count, p16 expression and VEGF expression (rs=−0.232, P=0.033 and rs=−0.252, P=0.020), and a positive correlation between CD8+T lymphocyte count and HPV infection, Ki-67 proliferation index, p16 expression and VEGF expression (rs=0.220, P=0.043; rs=0.346, P=0.001; rs=0.350, P=0.001 and rs=0. 363, P=0.001). Logistic regression analysis showed that CD4+T lymphocyte count, p16 expression, VEGF gene expression and CD34 microvessel density were independent risk factors for CA complicated with HIV. Conclusion: In CA male patients with HIV, the decrease of CD4+T lymphocyte count, the active proliferation of epithelial cells, and the increase of angiogenesis in the CA tissues can be used as important indicators for the diagnosis and poor prognosis of CA.
