AbstractOBJECTIVES: to investigate whether hepatitis B surface antigen (HBsAg) and hepatitis B core-related antigen (HBcrAg) levels are useful to identify inactive carriers among HBeAg-negative patients infected by different HBV genotypes.
METHODS: 202 consecutive HBeAg-negative chronic hepatitis B patients, 135 inactive carriers and 67 with HBV activity, were prospectively followed during 1 year.
RESULTS: In HBeAg-negative patients, HBsAg levels differed across the different genotypes (p<0.001). The highest levels were observed in genotypes F or H (4.2±0.6 logIU/mL), followed by genotype E (3.4±1.1 logIU/mL), A (3.4±0.8 logIU/mL), and the lowest in genotype D (2.7±1.1 logIU/mL). Variations in HBsAg levels were similar in inactive carriers and patients with HBV activity. HBsAg <3 logIU/mL showed good performance for identifying genotype-D inactive carriers: 76% of genotype D inactive carriers met this cut-off versus ≤31% for genotypes A, E, F or H. However, in patients with genotype A, HBsAg levels ≤3.7 logIU/mL better classified inactive carriers. The combination of a single measurement of HBcrAg ≤3 logU/mL plus HBV DNA ≤2000 IU/mL yielded a positive predictive value and diagnostic accuracy >85% in all HBV genotypes, except genotype H or F, with values of 62.5% and 72.7%, respectively, for the two parameters.
CONCLUSIONS: HBsAg levels varied across genotypes in HBeAg-negative patients. HBsAg levels <3 log IU/mL were only useful for identifying genotype D inactive carriers. A single HBcrAg measurement ≤3 logU/mL plus HBV DNA ≤2000 IU/mL was highly accurate for identifying inactive carriers, regardless of their HBV genotype.

抽象
目标:
研究乙型肝炎表面抗原(HBsAg)和乙型肝炎核心相关抗原(HBcrAg)水平是否可用于识别不同HBV基因型感染的HBeAg阴性患者中的非活动性携带者。
方法:
202例HBeAg阴性慢性乙型肝炎患者,135例非活动性携带者和67例HBV活性,在1年内随访。
结果:
在HBeAg阴性患者中,不同基因型的HBsAg水平不同(p <0.001)。在基因型F或H(4.2±0.6logIU / mL)中观察到最高水平,随后是基因型E(3.4±1.1logIU / mL),A(3.4±0.8logIU / mL) ±1.1logIU / mL)。 HBsAg水平的变化在无活性携带者和具有HBV活性的患者中相似。 HBsAg <3logIU / mL对于鉴定基因型D失活载体显示出良好的性能:76%的基因型D失活载体满足该截止值,而基因型A,E,F或H为≤31%。然而,在基因型A ,HBsAg水平≤3.7logIU / mL更好地分类不活动载体。 HBcrAg≤3logU / mL加HBV DNA≤2000IU / mL的单次测量的组合在所有HBV基因型中除了基因型H或F外都具有阳性预测值和诊断准确性> 85%,值为62.5%和72.7 %,分别为两个参数。
结论:
HBsAg水平在HBeAg阴性患者中的基因型不同。 HBsAg水平<3log IU / mL仅可用于鉴定基因型D失活载体。单一HBcrAg测量≤3logU / mL加HBV DNA≤2000IU / mL对于鉴定无活性载体是高度准确的,不论其HBV基因型。
