The structure of integrated viral DNA in a hepatocellular carcinoma of a duck from Chi-tung county in China was analyzed. Three different clones of integrated viral DNA, lambda DHS 6-1, lambda DHS 6-2, and lambda DHE 6-2, were obtained from the neoplastic portion of the liver by molecular cloning. One of the three clones, lambda DHS 6-1, showed inverted repetition of integrated viral DNA with chromosomal flanking sequences. Another clone, lambda DHS 6-2, showed a head-to-head configuration of the core and surface gene regions of duck hepatitis B virus (DHBV) DNA. The virus-chromosome junctions were often located near direct repeat 1 or 2 of DHBV DNA in three independent clones. Nucleotide sequences at the virus-virus junctions in two clones, lambda DHS 6-1 and 6-2, indicated the possible rearrangement of chromosomal DNA and recombination of viral DNA. DHBV DNA appears to be integrated into the genome of hepatocytes in a manner similar to that of human and woodchuck hepatitis viruses. Thus, the duck system may serve as a useful animal model for the study of human hepatocarcinogenesis.

Some studies have suggested an ethnic susceptibility to Hypersensitivity Syndrome. We did a 7-year-prospective study in Guadeloupe whose population is mainly of African ancestry, and has free access to modern care facilities. Most patients included were Afro-Caribbeans (26/28), and females (20/28). However, ethnic distribution did not reach significant conclusions. Annual incidence rate was estimated at 0.9/100,000. Medium incubation and duration were 33 and 66 days respectively. Two patients with grade 4 hepatitis died from the syndrome. Two thirds of the patients were given prednisone, which usually alleviated the systemic symptoms, but did not prevent their development (in 5 patients) nor death. Carbamazepine, allopurinol, and minocycline accounted for 2/3 of the cases. Sixty four percent of the causative prescriptions were judged inappropriate. DHS appeared as the most frequent type of severe systemic drug reaction in this population, and may largely be prevented by rational prescribing.

Dapsone is a sulfone-type drug used widely for different infectious, immune, and hypersensitivity disorders as an antibacterial treatment alone or in combination for leprosy and sometimes for infected skin lesions. DHS is a severe idiosyncratic adverse reaction with multi-organ involvement. However, acute necrotic hepatitis requiring an emergent LT is rare. Herein, we report a case of 12-yr-old girl who suffered from fulminant hepatitis and multi-organ failure due to DHS for PPD. She was saved by emergent LDLT. A high index of suspicion and rapid diagnosis are necessary not to miss this potentially lethal but rare disease.
