艾滋病元氣虛損證機的研究.pdf

1、艾滋病是由人類免疫缺陷病毒(human immunodeficiency virus,HIV)感染所導致的以進行性CD<,4><'+>細胞數(shù)量減少與功能受損為特征的機體免疫缺陷、并易繼發(fā)多種機會性感染和腫瘤的一系列綜合征.該病潛伏期長、傳播速度快、病情復雜深重,目前仍無法治愈,成為當今世界矚目的課題.中醫(yī)關于艾滋病的研究尚處于探索階段,特別是通過艾滋病大宗病例的臨床證候觀察進行病因病機探討、中醫(yī)藥治療艾滋病的臨床試驗與療效評價等方面研究

2、還十分薄弱.為此,該研究通過對72例艾滋病患者常見中醫(yī)癥候/證候及218例舌象的觀察,運用中醫(yī)元氣理論與溫疫理論作指導,分析其病因病機及演變規(guī)律,并以疫毒致元氣虛損的證機作為重點進行深入探討;同時,通過觀察72例患者外周血CD<,4><'+>、CD<,8><'+>、CD<,45>RA<'+>T淋巴細胞亞群改變,分析艾滋病免疫損傷與元氣虛損的相關性,以探索艾滋病元氣虛損的細胞免疫學基礎,也為中醫(yī)微觀辨證提供線索;此外,借助艾滋病"十五"國

3、家科技攻關課題,通過益氣養(yǎng)陰、清熱解毒法治療6 3例早中期HIV/AIDS患者臨床隨機雙盲對照試驗的療效觀察,佐證溫邪疫毒致氣陰損傷、元氣虧虛是艾滋病病變過程中重要病機之一.該研究還采用益氣養(yǎng)陰、清熱解毒法,對63例早中期HI V/AIDS患者進行臨床隨機雙盲對照試驗的療效觀察,臨床結果初步分析顯示(未揭盲情況下):①對HIV病毒載量的影響,63例患者總體觀察結果,總有效29例、占46.03％,初步顯示該方案可能具有一定降低HIV病毒載

4、量作用.②對機體免疫功能的影響,63例患者中,CD<,4><'+>細胞數(shù)上升者20例(31.75％),下降者43 例(68.25％),表明該益氣養(yǎng)陰、清熱解毒法方案對機體免疫功能可能有一定保護作用.③在臨床癥候方面,乏力、消瘦、少氣懶言、自汗、盜汗、脫發(fā)、咳嗽、氣短/氣喘、納呆、腹瀉、低熱、五心煩熱等,63例患者總體發(fā)生率治療前后初步分析,顯示有不同程度的降低,說明該治療方法對上述主要癥候有一定改善作用.通過上述研究初步揭示,艾滋病中醫(yī)

5、病變特點為病及三焦內(nèi)外、病性虛實錯雜;艾滋病早中期中醫(yī)證機特點為熱毒濁瘀、氣陰兩傷、元氣虛損;艾滋病病變發(fā)展趨勢呈現(xiàn)出命門三焦元氣衰竭、虛者愈虛,熱毒濁瘀阻遏三焦、實者愈實;以扶正祛邪為原則的益氣養(yǎng)陰、清熱解毒法是艾滋病早中期有效治法之一,從而佐證了溫邪疫毒致氣陰損傷、元氣虛損是艾滋病病變發(fā)展過程中重要證機之一,也為探索艾滋病從腎命元氣虛衰為本、邪毒為標的診治體系提供了重要依據(jù).主題詞:艾滋病 元氣損傷 證候 病機 扶正祛邪 療效評價
