Herpes simplex virus hepatitis in a child: case report and review

Herpetic gingivostomatitis with severe hepatitis in a previously healthy child

A previously healthy boy aged 9 years and 11 months was admitted due to herpetic gingivostomatitis with poor intake. He also had fever, neutropenia, and elevated serum aminotransferase level (> 1000 IU/mL). Prolonged prothrombin time, mild gastrointestinal hemorrhage and transient decreased conscious level were noted during hospital days 2 and 3. Intravenous acyclovir therapy commenced on hospital day 2 and his serum aminotransferase level peaked (> 4000 IU/mL) on hospital day 3 and then improved gradually. A throat swab was positive for human herpes simplex virus (HSV)-1, serological test was positive for acute primary HSV-1 infection, and a blood specimen was also strongly positive for HSV-1 by polymerase chain reaction. He received a 14-day course of intravenous acyclovir and recovered uneventfully. Herpetic gingivostomatitis, although mostly benign and self-limited, may be complicated with severe hepatitis, even in immunocompetent hosts.

Fatal fulminant herpes simplex hepatitis secondary to tongue piercing in an immunocompetent adult: a case report

Introduction

Herpes simplex infection is most commonly a benign, self-limiting disease with mucocutaneous lesions and mild viremia. Immunosuppressed patients are at a higher risk of disseminated infection, as are neonates and pregnant women. The incidence of fulminant herpes simplex virus hepatitis is extremely low, and the diagnosis is often missed due to the lack of specific signs or symptoms.

Case presentation

We present the case of an immunocompetent, previously healthy young woman who contracted herpes simplex virus, presumably through a recent tongue piercing, which progressed to fulminant hepatitis and death.

Conclusion

Despite aggressive medical therapy, fulminant herpes simplex virus hepatitis is fatal in the majority of patients. We present a review of the literature, which shows that immunocompetent adults have rarely been affected by fulminant herpes simplex virus hepatitis. Initiation of empirical therapy is warranted in patients with progressive hepatic failure with no other underlying cause. Acyclovir therapy has proven effective in some patients, but is less effective in patients who present in advanced stages of infection.

Viral diseases of the liver in children: diagnostic and differential diagnostic considerations

This review summarizes the general histologic features of acute and chronic hepatitides and highlights those morphologic findings that may suggest or be diagnostic of a specific agent or etiology. The main epidemiologic, clinical, and pathologic features of the hepatotropic viruses are discussed, with an emphasis on pediatric studies and the differential diagnosis of hepatitis in childhood.
