Hiroshi Adachi, Shuichi Kaneko, Eiki Matsushita, Yutaka Inagaki, Masashi Unoura, Kenichi Kobayashi – 1 December 1992 – The natural history of chronic hepatitis B patients who spontaneously cleared serum HBsAg was investigated. A total of 351 patients with chronic hepatitis B were observed in our hospital for at least 3 yr. Seven of these patients became HBsAg negative during the follow‐up period. HBsAg disappeared within 6 mo (range = 11 to 169 days, mean = 70 days) after acute elevation of ALT.
