【摘要】:目的對(duì)比研究國產(chǎn)1型艾滋病病毒(HIV-1)核酸定量試劑與兩個(gè)進(jìn)口試劑的相關(guān)性和差異,以期應(yīng)用國產(chǎn)核酸定量試劑評(píng)價(jià)中國抗病毒治療患者病毒學(xué)效果的可行性。方法應(yīng)用美國國家衛(wèi)生研究院病毒學(xué)質(zhì)量評(píng)價(jià)項(xiàng)目(VQA)發(fā)放的HIV-1核糖核酸(RNA)血清樣品,比較一種國產(chǎn)核酸定量試劑與國內(nèi)市場常規(guī)使用的兩個(gè)進(jìn)口試劑,在測定病毒載量上的相關(guān)性和一致性。對(duì)國產(chǎn)和進(jìn)口核酸定量試劑檢測HIV-1病毒載量的結(jié)果進(jìn)行配對(duì)t檢驗(yàn),線性回歸分析和Bland-Altman分析。結(jié)果國產(chǎn)試劑和兩個(gè)進(jìn)口試劑的檢測結(jié)果的線性相關(guān)系數(shù)R2分別為0.94、0.93(P0.000 1);Bland-Altman分析三種試劑病毒載量的結(jié)果具有較高的一致性,國產(chǎn)試劑定量值與VQA病毒載量值線性相關(guān)系數(shù)R2=0.97,P0.000 1,定量單位轉(zhuǎn)換系數(shù)為1IU/mL=0.79拷貝/mL。結(jié)論國產(chǎn)HIV-1核酸定量試劑與進(jìn)口試劑在定量檢測結(jié)果上有較好的相關(guān)性和一致性,而且國產(chǎn)試劑在價(jià)格上具有優(yōu)勢,在一定范圍內(nèi)可以應(yīng)用于抗病毒治療效果的評(píng)價(jià)。
[Abstract]:Objective to study the correlation and difference between domestic and imported nucleic acid quantitative reagents of HIV-1, and to evaluate the feasibility of using domestic nucleic acid quantitative reagents to evaluate the virological effect of antiviral therapy in China. Methods the serum samples of HIV-1 ribonucleic acid (HIV-1) RNA from the virology quality evaluation project of the National Institutes of Health (NIH) were used to compare a domestic nucleic acid quantitative reagent with two imported reagents which were routinely used in the domestic market. Correlation and consistency in the determination of viral load. The results of detection of HIV-1 viral load by domestic and imported nucleic acid quantitative reagents were analyzed by paired t test, linear regression analysis and Bland-Altman analysis. Results the linear correlation coefficient R ~ 2 of domestic reagent and two imported reagent were 0.94 ~ 0.93 P0.000 ~ (-1) Bland-Altman analysis results of virus load of three reagents had high consistency. The linear correlation coefficient between the quantitative value of domestic reagents and the load value of VQA virus was R _ (2) O _ (97) (P _ (0.000 1)), and the quantification unit conversion coefficient was 1IU/mL=0.79 copy / mL. Conclusion there is good correlation and consistency between domestic HIV-1 nucleic acid quantitative reagents and imported reagents, and domestic reagents have advantages in price and can be used to evaluate the effect of antiviral therapy in a certain range.
