Figure 1

Time course of hepatic enzymes and haematological, immunological, and virological parameters. Values are shown as percentages of reference values over time (t = 0: time of initial symptoms). Reference values were chosen as the lowest of the normal range, with the exception of ALAT, for which the highest normal range value was used. Time points for intravenous immunoglobulin (IVIG), prednisolone treatment, liver biopsy, and parvovirus B19 DNA status are indicated.
