Kirn, Nam, Bae, Ha, Kim, Kang, and Lee: A Survey of Hepatitis B Virus Markers by EIA Method among Steel Manufacturing Workers

Abstract

A study for seroprevalence of Hepatitis B virus markers (HBsAg, Anti-HBs, HBeAg and Anti-HBe) by EIA method and the Liver Function Test(SGOT and SGPT) using kinetic method was carried :out from January; to October 1995 :among male workers of a .major iron and steel manufacturing company, located, in Pohang.
The results were as follows;
1. The distribution of hepatitis B virus markers showed that the proportions of HBsAg(+)/Anti-HBs (-), HBsAg(-)/Anti-HBs (+) 'and HBsAg(+)/Anti-HBs (+) were 8.1%, 60.5% and 0.1%, respectively. The positive rate of HBsAg in all subjects was 8.2% whereas that of anti-HBs was 60.6%.
2. The proportions of HBsAg(+)/Anti-HBs (-) and HBsAg(-)/Anti-HBs (+) increased significantly with age. While the distribution of hepatitis B virus markers exhibited no significant differences among the groups classified by educational background or work type.
3. The proportion of drinkers in HBsAg (+)/Anti-HBs (-) (73; 9%) was significantly lower than those of HBsAg (-)/Anti-HBs (-) and HBsAg (-)/Anti-HBs (+) (84.6% and 85.7% respectively). The proportions of smoking for the three groups of HBsAg (-)/Anti-HBs(+),-HBsAg (+)/Anti-HBs (-) and HBsAg (-)/Anti-HBs (-) were 54.3%, 53.7% and 53.0%, respectively (p<0.01). The proportion of the subjects with abnormal liver function test in HBsAg (+)/Anti-HBs (-) was 40.1%, whereas those in HBsAg (-)/Anti-HBs (-) and HBsAg(-)/Anti-HBs (+) were 21.9% and 18.4%, respectively.
4. The distribution of e Ag markers among HBsAg (+) subjects showed that the proportions of HBeAg(+)/Anti-HBe(-), HBeAg(-)/Anti-HBe(+) and HBeAg(+)/Anti-HBe(+) were 31.3%, 55.0% and 1.6%, respectively. The proportion of HBeAg(+)/Anti-HBe(-) decreased significantly with age and those of HBeAg(-)/Anti-HBe(-) and HBeAg(-)/Anti-HBe(+) increased with age. The positive rate of HBeAg among HBsAg (+) subjects was 32.9%.
In conclusion, as a screening method, EIA is. recommended to test hepatitis B virus markers, especially when examining Anti-HBs more sensitively. For the workers of the iron and steel manufacturing company studied, liver diseases caused by other than hepatitis B should be given a special care including an education avoiding alcohol drinking.
