Abstract
BACKGROUND/AIMS
Consecutive patients originally diagnosed with acute non-A, non-B hepatitis were followed up to assess the long-term morbidity and mortality and to re-evaluate the etiology in surviving patients.
METHODS
Follow-up was performed in 178 patients with acute non-A, non-B hepatitis enrolled in the Copenhagen Hepatitis Acuta Programme in the period 1969-1987. Mortality and morbidity were assessed using: i) death certificates and ii) diagnoses at discharge following all somatic admissions. All patients who were alive were offered a re-examination encompassing clinical, biochemical and virological evaluation.
RESULTS
After a median of 23 years, 71 (40%) had died and seven (4%) were untraceable. Overall mortality and mortality due to cirrhosis and accidents, mainly intoxication with drugs, were significantly higher compared to those of an age- and sex-matched Danish population. Chronic hepatitis had been diagnosed in 19 (11%) and cirrhosis in 16 (9%). Of 100 patients who were alive, 57 accepted a re-examination. Anti-HCV was detected in 24 (42%) and 19 (33%) were HCV-RNA positive. Of the viremic patients, 11 (58%) had elevated P-ALT, but only three (16%) had already been diagnosed with HCV infection. A history of intravenous drug use was tantamount to anti-HCV positivity.
CONCLUSIONS
Danish patients with community-acquired acute non-A, non-B hepatitis had an increased mortality due to liver cirrhosis during the first years after the acute infection. Alcohol was the etiological agent in several cases, but HCV infection may also have been present. However, the long-term HCV-related morbidity and mortality were low.
