Answer

Characteristic findings in dengue fever are thrombocytopenia (platelet count < 100 x 109/L), leukopenia, and mild-to-moderate elevation of aspartate aminotransferase and alanine aminotransferase values. Jaundice and acute liver failure are uncommon. Peak liver enzyme levels occur later than other complications in adults studied prospectively in Vietnam. Enzyme levels begin to rise during the early stage and peak during the second week. Clinically severe involvement was found to be idiosyncratic and infrequent but did contribute to severe bleeding.
