Infection with herpes simplex virus (HSV) is a common worldwide problem. Primary infection with HSV-1 rarely causes significant problems although widespread involvement in atopic eczema can be life-threatening as may associated encephalitis. Keratoconjunctivitis, pharyngitis and hepatitis can also complicate primary infection. Twenty to 40% of the population at some stage have recurrent orolabial infections with HSV although in only 1% of these cases is this recurrence severe. Recurrent erythema multiforme appears to be associated with HSV-65% of patients are thought to have preceding herpes labialis. Many primary and recurrent infections with HSV-1 require little more than topical antiseptic therapy to control secondary infection. Systemic acyclovir, however, is indicated in various situations including complicated primary infection, infection in neonates, eczema herpeticum, HSV infections in the immunocompromised, and recurrent erythema multiforme. In the latter, prophylactic treatment with 6 months acyclovir appears to be effective.

Acute liver failure is a life threatening disease mostly triggered by drug-induced or toxic liver damage or viral hepatitis. Herpes Simplex virus (HSV) hepatitis is rare and accounts for only 1% of all acute liver failures. The importance of HSV-induced acute liver failure is based on its extremely severe clinical course with lethality rates of almost 75%. HSV hepatitis is just one of several clinical manifestations of HSV sepsis leading more frequently to encephalitis, pneumonia and esophagitis. Local herpes infection or recurrence of dermal lesions (herpes labialis, herpes genitalis), however, is common and account for the high prevalence of HSV-1 or HSV-2 infection in adults. Another rare entity is visual dissemination, which mostly affects immunocompromised patients. Compromised cellular immunity is a major risk factor for HSV sepsis because of either primary infection or reactivation of occult chronic HSV infection. Delayed diagnosis without antiviral therapy significantly contributes to the unfavorable outcome. Typically, anicteric hepatitis is seen in patients with HSV hepatitis. Because of its low incidence, however, and the lack of dermal manifestations, HSV hepatitis is rarely considered in the context of acute liver failure. In addition, diagnostic tests might not always be available. Therefore, it is a generally accepted consensus to begin antiviral therapy pre-emptively with acyclovir in cases of acute liver failure of unknown origin, in which high urgency (HU) liver transplantation remains the only therapeutical option. Even in the case of early specific therapy, sepsis may prevail and the indication for HU transplantation must be evaluated carefully. The outcome after liver transplantation for HSV-induced liver failure with reported survival rates of more than 40% is good. Because of the risk of recurrence, lifelong prophylaxis with acyclovir is recommended.

We present a rare case of a healthy, non-pregnant, middle-aged and immunocompetent woman who underwent laparoscopic cholecystectomy for acute cholecystitis with a post-operative course complicated by herpes simplex virus type 1 (HSV-1) hepatitis secondary to post-surgical inflammation. Her initial post-operative course was complicated by intermittent fevers, leukocytosis, jaundice, elevated transaminases, and right upper quadrant abdominal pain, and she was subsequently placed on broad-spectrum antibiotics with no improvement. During her hospital course, the patient developed herpes labialis, and HSV-1 hepatitis was confirmed by serology and HSV-1 polymerase chain reaction (PCR), in lieu of a liver biopsy. After this was discovered, the patient was placed on valacyclovir and had a successful response. The importance of this case is to emphasize the possibility of herpes simplex virus (HSV) hepatitis as a post-operative complication and the benefit of early empiric antiviral treatment.
