The cyclic behaviour of NANB hepatitis as basis for standardized diagnostic.

Efforts were made to characterize the clinical and biochemical behaviour of NANB hepatitis in 51 patients. 15 patients had posttransfusion NANB hepatitis, 36 a sporadic form of the disease. The patients' complaints predominantly were nausea and vomiting (64%), in about each 25% cardial complaints, lassitude, muscle pain and fever were observed. An eczema in a kind of maculopapular eruptions was frequently seen. The ratio of SGOT/SGPT was almost never less 1.0, Gamma-GT was consistently increased. The biochemical changes relapsed frequently. In posttransfusion NANB hepatitis the relapses were observed to occur predominantly around day 21, 28, 42, 49, 56, 63, 70, 77, and in further weekly intervals.
