AB Patients with the acquired immune deficiency syndrome (AIDS)
occasionally develop hepatitis, pneumonia or esophagitis due to herpes
simplex virus type 2 (HSV-2) infection. HSV hepatitis is a rare but
serious complication in liver transplantation. Acyclovir-resistant HSV
strains may emerge in immunocompromised patients. Following
intraperitoneal inoculation, HSV-2 induces necrotizing hepatitis in
mice. We studied the virus spread and mortality following
intraperitoneal inoculation of HSV-2 RK (an acyclovir-resistant
recombinant virus with altered thymidine kinase activity) as compared to
its parent virus 8620K. Neither the 50% lethal dose (LD50) nor the
average survival time was significantly different between the two
strains. Parenteral acyclovir treatment was found to be effective
against 8620K but not RK infection. Parenteral foscarnet treatment was
effective against both RK and 8620K, and also inhibited the spread of
either virus to the liver, spinal cord and brain. Peroral foscarnet
administration was found to prevent the virus growth in the liver.
