HSV Hepatitis in Pregnancy: A Review of the Literature.

Abstract

Herpes simplex virus (HSV) hepatitis is a rare condition with a high mortality rate. Immunocompromised individuals, including pregnant women, are the most susceptible. When primary infection occurs during pregnancy, risk for disseminated HSV is greatly increased. Disseminated HSV can manifest in the form of HSV hepatitis. We aim to review the literature and summarize what is known about HSV hepatitis in pregnancy to aid in the diagnosis and treatment of this condition. A literature search of PubMed and Web of Science was performed. A total of 237 citations were found. All citations were independently reviewed. Thirty-eight full-text articles were identified and included in this review. Additional data from 1 unpublished case from our institution was included. Fifty-six cases were included with average gestational age at diagnosis of 30 weeks. Patients presented with a wide variety of gastrointestinal, respiratory, neurologic, and urogenital symptoms. The most common examination findings were fever and abdominal tenderness. Only 18.2% of patients had a vesicular rash. All patients had a transaminitis, and 85% had positive viral cultures. A multitude of treatments were used with the majority of favorable outcomes occurring after treatment with acyclovir. Although HSV hepatitis is rare, it carries a mortality rate of up to 39% for mothers and neonates. Therefore, it is crucial that HSV hepatitis be included on the differential diagnosis when a patient presents with fever and transaminitis. When HSV hepatitis is suspected, empiric therapy with acyclovir can be initiated with no additional risk to the fetus.
