至今为止,日本虽有关于δ感染症方面的少数病例报告,但均未能从流行病学方面阐明其感染情况。这次作者与国立病院共同协作,调查研究了日本δ感染症的现状。作者共调查了31所国立病院,调查对象是确诊为HBsAg 阳性的肝病患者合计1307例。其中慢性肝炎患者760例,肝硬变患者262例,无症状携带者145例,急性肝炎患者63例,肝癌患者56例,其他肝病患者21例。这里说的无症状携带者原则是指过去曾有过肝功能异常史的患者。作者除根据掌握的临床数据外还采集了部分血清,用放射免疫测定法统一测定了δ抗体。
To date, Japan has reported few cases of delta-infectious disease, but none of them have elucidated their epidemiology epidemiologically. The author collaborated with the National Hospital to investigate the status quo of Japanese infectious disease. The authors surveyed 31 state-owned hospitals for a total of 1,307 liver disease cases that were diagnosed as HBsAg-positive. Among them, there were 760 cases of chronic hepatitis, 262 cases of cirrhosis, 145 cases of asymptomatic carriers, 63 cases of acute hepatitis, 56 cases of liver cancer and 21 cases of other liver diseases. The principle of asymptomatic carrier here refers to patients who have had a history of abnormal liver function in the past. In addition to the author according to the clinical data collected in addition to part of the serum collected by radioimmunoassay method for the determination of δ antibody.
