Abstract
BACKGROUND:

The cure for hepatitis B is defined as the hepatitis B surface antigen (HBsAg) seroclearance and/or seroconversion. Predictors of spontaneous seroconversion are not well described. The objective of this study is to identify predictors of spontaneous HBsAg seroconversion from community practice.
METHODS:

We performed a matched analysis of patients who HBsAg seroconverted (cases) and patients who did not HBsAg seroconvert (control) in a 1:5 ratio according to date of clinic visit between 2014 and 2019 in a large community practice situated in Los Angeles area. Baseline laboratory and clinical data were collected. Univariate analysis and 2-sided t tests were performed, χ test for proportions, and logistic regression.
RESULTS:

We identified 14 cases and 70 controls. The mean (±SD) ages of the cases and controls were 53.6 (±12.2) and 49.5 (±13.1), respectively (P=0.45). Most patients were women, and all patients were of Asian descent. There were statistically significant mean (±SD) baseline differences between cases and controls in HBsAg titers (459.8±311.0 and 782.0±393.3 IU/mL, P=0.01) and alanine aminotransferase (ALT) values (17.6±4.4 and 25.1±16.7 IU/mL, P<0.01), respectively. Baseline hepatitis B virus DNA and other pertinent laboratory values did not differ between cases and controls. Eleven of 14 cases (79%) and 11 of 70 controls (16%) baseline HBsAg titers were <1000 IU/mL (P<0.01). The results of a logistic regression demonstrated that HBsAg titers and ALT values were predictor variables for HBsAg seroconversion (P=0.01 and <0.01, respectively).
CONCLUSIONS:

Spontaneous HBsAg seroclearance and seroconversion is an uncommon event in patients with chronic hepatitis B. The most important predictors of seroconversion are HBsAg titers<1000 IU/mL and low baseline ALT values.

抽象
背景:

乙型肝炎的治愈定义为乙型肝炎表面抗原(HBsAg)血清清除和/或血清转化。没有很好地描述自发血清转化的预测因素。这项研究的目的是从社区实践中确定自发性HBsAg血清转化的预测因素。
方法:

我们根据2014年至2019年之间在洛杉矶地区的大型社区实践中的门诊日期,以1:5的比例对HBsAg血清转化的患者(病例)和未进行HBsAg血清转化(对照)的患者进行了匹配分析。收集基线实验室和临床数据。进行了单变量分析和两面t检验,对比例进行了χ检验,并进行了逻辑回归。
结果:

我们确定了14个病例和70个对照。病例和对照组的平均年龄分别为53.6(±12.2)和49.5(±13.1)(P = 0.45)。大多数患者是女性,所有患者均为亚洲血统。病例与对照组之间的HBsAg滴度(459.8±311.0和782.0±393.3 IU / mL,P = 0.01)和丙氨酸转氨酶(ALT)值(17.6±4.4和25.1±16.7 IU)之间存在统计学意义的平均(±SD)基线差异/mL,P<0.01)。基线乙型肝炎病毒DNA和其他相关实验室值在病例与对照之间没有差异。 14例基线HBsAg滴度中的11例(79%)和70例对照中的11例(16%)<1000 IU / mL(P <0.01)。 Logistic回归结果表明,HBsAg滴度和ALT值是HBsAg血清转化的预测变量(分别为P = 0.01和<0.01)。
结论:

在慢性乙型肝炎患者中,自发性HBsAg血清清除和血清转化是罕见的事件。血清转化的最重要预测指标是HBsAg滴度<1000 IU / mL和基线ALT值低。
