[摘要] 目的 觀察乙型肝炎病毒相關(guān)性腎炎(HBV-GN)患者腎臟組織中HBsAg、HBcAg的表達(dá)情況。方法 以50例HBV-GN患者為研究對(duì)象,另隨機(jī)選擇20例非乙型肝炎病毒相關(guān)性腎炎(NHBV-GN)患者作為對(duì)照組,用間接免疫熒光法檢測(cè)腎穿刺活檢組織HBsAg、HBcAg的表達(dá)。結(jié)果 HBV-GN患者腎組織中可檢測(cè)HBsAg、HBcAg陽性顆粒,陽性率分別70%(35/50),24%(12/50);20例(NHBV-GN)患者腎臟組織HBsAg、HBcAg均未檢出。與HBV-GN差異有統(tǒng)計(jì)學(xué)意義(P<0.05)。結(jié)論 HBsAg、HBcAg免疫熒光標(biāo)記是診斷HBV-GN的重要指標(biāo),HBV在腎組織內(nèi)存在感染及復(fù)制,其在乙型肝炎病毒相關(guān)性腎炎的發(fā)病機(jī)制中具有重要作用。

[Abstract] Objective To observe the HBsAg and HBcAg expression in the renal tissue in hepatitis B virus associated glomerulonephritis(HBV-GN). Methods We selected 50 cases of HBV-GN as research group and the other randomly selected 20 cases of non-HBV-GN(NHBV-GN)as control group and used indirect immunofluorescence assay to detect the HBsAg and HBcAg expression in the renal puncture biopsies. Results The HBsAg and HBcAg-positive particles in the HBV-GN renal tissue could be detected,with the positive rates of 70%(35/50)and 24%(12/50),while HBsAg and HBcAg failed to be detected in the kidney tissue of 20 cases of NHBV-GN,with a significant difference between the two groups(P<0.05). Conclusion The immune fluorescence detection of HBsAg and HBcAg is an important indicator in the diagnosis of HBV-GN. HBV plays an important role in the kidney tissue infection and replication and the pathogenesis of HBV-GN.

乙型肝炎病毒相關(guān)性腎炎(HBV-GN)是指乙型肝炎病毒感染人體后,病毒抗原HBsAg、HBcAg、HBeAg與體內(nèi)相應(yīng)抗體形成免疫復(fù)合物沉積在腎組織中,引起免疫復(fù)合物性腎小球腎炎[1,2]。本次研究以50例HBV-GN患者為研究對(duì)象,另隨機(jī)選擇20例非乙型肝炎病毒相關(guān)性腎炎(NHBV-GN)患者(剔除狼瘡性腎炎等引起HBsAg、HBcAg非特異性沉積的腎炎)作為對(duì)照組,用間接免疫熒光法檢測(cè)腎穿刺活檢組織HBsAg、HBcAg的表達(dá),以探討HBsAg、HBcAg的免疫熒光檢測(cè)在乙型肝炎病毒相關(guān)性腎炎診斷中的應(yīng)用。
