摘要: 目的 探讨血清抗延胡索酸水合酶抗体(抗-FH)诊断自身免疫性肝炎(AIH)及其鉴别诊断的价值。方法 2018年2月~2019年5月我院内科收治的166例肝病患者,其中AIH患者52例,慢性乙型肝炎(CHB)患者81例和药物性肝损伤(DILI)患者33例,采用ELISA法检测血清抗-FH和抗核抗体(ANA)。结果 AIH患者血清GGT、ALP和IgG水平分别为(304.6±28.1)U/L、(258.1±24.0)U/L和(24.7±1.9)g/L,显著高于CHB患者【分别为(104.5±12.3)U/L、(85.7±9.2)U/L和(15.2±1.5)g/L,P<0.05】,其血清IgG水平也显著高于DILI患者【(14.8±1.2)g/L,P<0.05】,三组血清TBIL和ALT水平差异无统计学意义(P>0.05);AIH组血清抗-FH阳性率为36.5%,显著高于DILI组的6.1%或CHB组的3.7%(P<0.05);AIH组血清ANA阳性率为73.1%,显著高于DILI组的54.5%或CHB组的50.6%(P<0.05);血清抗-FH诊断AIH的灵敏度、特异度、约登指数、阳性预测值和阴性预测值分别为36.5%、95.6%、0.3、35.2%和76.8%,而血清抗-FH联合ANA诊断的灵敏度、特异度、约登指数、阳性预测值和阴性预测值则分别为76.9%、44.7%、0.2、38.8%和80.9%,提高了诊断的灵敏度,但特异度大大降低。结论 血清抗-FH诊断AIH患者的特异性很高,但灵敏度较低,在特定情况下对鉴别诊断可能具有很大的帮助。

Abstract: Objective The aim of this study was to explore the diagnostic value of serum anti-fumarate hydratase (anti-FH) in patients with autoimmune hepatitis (AIH). Methods 166 patients with liver disease, including AIH in 52, chronic hepatitis B (CHB) in 81 and drug-induced liver injury (DILI)]in 33, were recruited in our hospital between February 2018 and May 2019. Serum anti-FH and antinuclear antibody were detected by ELISA. Results Serum GGT, ALP and IgG levels in patients with AIH were (304.6±28.1)U/L, (258.1±24.0)U/L and (24.7±1.9)g/L, significantly higher than 【(104.5±12.3)U/L, (85.7±9.2)U/L and (15.2±1.5)g/L, respectively, P<0.05】 in patients with CHB and serum IgG level was also much higher than 【(14.8±1.2)g/L, P<0.05】 in patients with DILI, and serum bilirubin and ALT levels in the three groups were not significantly different (P>0.05); serum anti-FH positive rate in patients with AIH was 36.5%, significantly higher than 6.1% in patients with DILI or 3.7%(P<0.05) in those with CHB; serum ANA positive rate in patients with AIH was 73.1%, significantly higher than 54.5% in DILI patients or 50.6%(P<0.05) in CHB patients; the sensitivity (Se), specificity (Sp), Yorden index, positive predictive value and negative predictive value by serum anti-FH in diagnosing AIH were 36.5%, 95.6%, 0.3, 35.2% and 76.8%, while those by serum anti-FH and ANA combination were 76.9%, 44.7%, 0.2, 38.8% and 80.9%, respectively, meaning the Se increased, while the Sp decreased greatly. Conclusion Serum anti-FH has a high diagnostic specificity for patients with AIH, which under some circumstances might have a good differential effect in clinical practice.
