河北省HIV-1分子流行病學(xué)和耐藥基因變異研究

河北省HIV-1分子流行病學(xué)和耐藥基因變異研究摘要：

本研究對(duì)河北省HIV-1分子流行病學(xué)和耐藥基因變異進(jìn)行了調(diào)查。共收集了2003年至2019年河北省HIV感染者血樣145份，對(duì)其進(jìn)行病毒基因型鑒定和藥物耐藥性檢測(cè)。

結(jié)果顯示，河北省HIV感染者主要為男性，其中男男性接觸是主要的傳播方式。HIV-1的前體蛋白編碼基因（gag和pol）序列分析表明，B型和CRF01_AE型是河北省HIV流行的主要亞型。藥物敏感性檢測(cè)結(jié)果顯示，在河北省HIV感染者中，多數(shù)患者對(duì)抗逆轉(zhuǎn)錄病毒藥物和蛋白酶抑制劑藥物敏感，但存在病毒對(duì)某些藥物的耐藥性。

此外，我們還對(duì)河北省HIV感染者中耐藥基因突變進(jìn)行了分析，發(fā)現(xiàn)其中多個(gè)位點(diǎn)存在藥物耐藥突變，并且這些耐藥基因變異與患者接受的抗逆轉(zhuǎn)錄病毒治療方案相關(guān)。這些結(jié)果有助于為河北省HIV感染者的治療提供更加有效和個(gè)性化的治療策略。
