A 46 years old female patient was admitted with jaundice, fatigue and
dull right upper abdominal pain. Transaminases were markedly elevated.
By liver biopsy chronic active hepatitis could be proven histological
ly without establishing a cause exhausting all diagnostic possibilitie
s. The hepatitis was therefore classified as cryptogenic. The gall bla
dder was removed when showing signs of cholecystitis without essential
changes in symptoms (histologically chronic acalculous cholecystitis)
. As there are cases of seronegative autoimmune hepatitis and as there
was evidence for autoimmune hepatitis from several findings, a therap
eutic trial with steroids was initiated. Rapidly symptoms disappeared,
transaminases decreased to normal values and the inflammatory activit
y was markedly reduced on control liver biopsy after six months.
