acyclovir and Emergencies

A young woman presented with a febrile illness in the third trimester of pregnancy. Laboratory investigation revealed severe acute hepatitis with thrombocytopenia and coagulopathy. Liver injury progressed despite emergent caesarian section and delivery of a healthy infant. Therefore, therapeutic plasma exchange (TPE) was performed on three consecutive days post-partum for a presumed diagnosis of acute liver failure (ALF) associated with pregnancy due to hemolysis, elevated liver enzymes, and low platelets (HELLP) or acute fatty liver of pregnancy (AFLP). Treatment with TPE was followed by biochemical and clinical improvement but during her recovery herpes simplex virus type 2 (HSV-2) infection was diagnosed serologically and confirmed histologically. Changes in the immune system during pregnancy make pregnant patients more susceptible to acute HSV hepatitis, HSV-related ALF, and death. The disease is characterized by massive hepatic inflammation with hepatocyte necrosis, mediated by both direct viral cytotoxicity and the innate humoral immune response. TPE may have a therapeutic role in acute inflammatory disorders such as HSV hepatitis by reducing viral load and attenuating systemic inflammation and liver cell injury. Further investigation is needed to clarify this potential effect. The roles of vigilance, clinical suspicion, and currently accepted therapies are emphasized.

A 38-year-old man was admitted to the Emergency Department suffering from an exacerbation of atopic dermatitis, fever and a burning sensation in the eyes. He was first treated with systemic corticosteroids. A subsequent dermatological and ophthalmological examination established the diagnosis of Kaposi-Juliusberg disease or eczema herpeticum with bilateral herpetic keratitis. Eczema herpeticum is an uncommon herpes simplex virus infection that occurs in patients with atopic dermatitis. Because it is a possible life-threatening condition, this disease must be recognized by all emergency physicians. The association with herpetic keratitis is not frequent but is a major ophthalmological problem. Treatment consists of the administration of high-dose intravenous acyclovir and acyclovir ophthalmic ointment.
