title: Demographics and outcomes of severe herpes simplex virus hepatitis: a registry-based study.
abstract: OBJECTIVE
  Herpes simplex virus hepatitis is a rare, but severe disease, thus far only documented by case reports and short series. The present study was based on the SRTR registry, and included all listed patients for liver transplantation from 1985 to 2009 with a diagnosis of HSV hepatitis.
  
  
  METHODS
  We assessed demographics and outcome of all listed patients, and further conducted a case-control study, matching each transplanted patient with 10 controls. Matching criteria included: transplant status, MELD score ±5, transplant date ±6 months, and age at transplant ±5 years. During the study period, 30 patients were listed for HSV hepatitis. Of the 30 listed patients, seven recovered spontaneously and five died, prior to transplantation. The remaining 10 children and eight adults were transplanted.
  
  
  RESULTS
  The chance of recovery was significantly higher in children than in adults (7/19 vs. 0/11, p=0.02). In children, survival was similar between HSV patients and the matched controls (5-year survival: 69% vs. 64%, p=0.89). Conversely, survival was poor in adult HSV (5-year survival: 38% vs. 65%, p=0.006), with 62% of them dying within the first 12 months. All three reported post-transplant deaths in children were independent from HSV. Among the seven adult post-transplant deaths, four were related to infection (bacterial, fungal, or viral).
  
  
  CONCLUSIONS
  Children listed for HSV hepatitis have a significantly better survival than adults both prior and after liver transplantation. While HSV fulminant hepatitis is an appropriate indication for liver transplantation in children, it should only be performed in selected adult patients in otherwise good condition.
