Introduction:
Hepatitis secondary to Herpes Simplex Virus (HSV) infection is a complication that often leads to fatal hepatic failure. Early treatment with the anti-viral drug, acyclovir, is life-saving. In view of the non-specific nature of the signs and symptoms associated with HSV hepatitis, diagnosis is often made late during the course of the disease; a factor that largely contributes to the high mortality rate of this treatable disease complication. There is thus a growing consensus in the field to initiate empirical treatment with acyclovir once suspicion of HSV hepatitis is raised even before reaching a conclusive diagnosis.
Presentation of case:
We present clinical evidence on the benefit of starting empirical acyclovir treatment on the outcome of patients suffering from HSV hepatitis. We report two cases of HSV hepatitis in children with cancer. One case presented with fulminant hepatitis which was fatal and the diagnosis was only reached post mortem. In the second case, there was enough suspicion of HSV hepatitis to start early empirical acyclovir therapy. The diagnosis was confirmed 48 hours following the initiation of treatment and the early intervention with anti-virals proved to be life-saving.
Discussion:
In both cases above, the following symptoms were shared; fever, elevated transaminase levels and mucositis without clear cutaneous lesions. HSV hepatitis should thus be considered in the differential diagnosis of immuonocomprimised patients exhibiting the above symptoms.
Conclusion:
Due to the frequent delay in HSV diagnosis and the safety of acyclovir, we recommend empirically administering acyclovir in patients suspected of HSV hepatitis.
