Aims: A prospective study was conducted to determine the aetiology and outcome of AHF in Thai children aged 1–15 years.

Methods: All serum samples were tested for anti-HAV IgM, HBsAg, anti-HBc IgM, anti-HCV, anti-HEV IgM and anti-dengue IgG and IgM. Further individual investigations were done according to the clinical impression.

Results: Forty subjects were enrolled from 14 centres during February 2000 to December 2001. Five cases were excluded owing to a lack of evidence of encephalopathy. The causes of AHF were dengue infection in 12 (34.3%), Wilson disease in 2 (5.7%), T-cell lymphoma in 2 (5.7%), ischaemic hepatitis in two (5.7%), haemophagocytic syndrome in one (2.8%), CMV in 2 (5.7%), Reye syndrome in one (2.8%) and unknown in 13 (37.1%) patients. The fatality rate was 68.6%. Eight of 24 (33.3%) deaths were caused by dengue infection.

Conclusions: Improvements in sanitation and socio-economic status as well as the implementation of hepatitis B vaccine in the Extended Programme on Immunization (EPI) are likely to be the reasons for the observed absence of AHF caused by hepatitis A and B. The study showed that dengue infection, on the other hand, was a major cause of AHF in Thailand.", pages = "17-23(7)", url = "http://www.ingentaconnect.com/content/maney/atp/2006/00000026/00000001/art00002" doi = "doi:10.1179/146532806X90565" }
