[Generalized herpesvirus infection with severe consumption coagulopathy in a newborn infant]
Insights
Acyclovir effectively treated disseminated neonatal herpes simplex virus (HSV) infection, controlling bleeding and enabling normal development. This highlights Acyclovir's potent antiviral action against HSV in newborns.
Area of Science:
- Virology
- Neonatal Medicine
- Pharmacology
Background:
- Neonatal herpes simplex virus (HSV) infection can lead to severe disseminated disease.
- Consumption coagulopathy and bleeding are critical complications in neonatal HSV.
- Early diagnosis and effective antiviral therapy are crucial for infant survival.
Observation:
- A mature newborn presented with disseminated HSV infection symptoms on the 6th day of life.
- Severe bleeding occurred due to consumption coagulopathy during the infection.
- Treatment with Acyclovir and fibrinogen replacement controlled bleeding.
Findings:
- Acyclovir demonstrated significant virostatic efficacy, inhibiting HSV DNA replication.
- The infant survived with normal psychologic and motor development post-treatment.
- Diagnosis was confirmed by HSV detection in blister fluid, cerebrospinal fluid, and serology.
Implications:
- Acyclovir is a highly effective treatment for severe neonatal HSV infections.
- Selective inhibition of viral DNA polymerase by Acyclovir is key to its efficacy.
- Prompt management of coagulopathy alongside antiviral therapy improves outcomes in neonatal HSV.
Abstract:
In a mature newborn the symptoms of a disseminated HSV infection were evident at the 6th day of life. Later on bleeding occurred as a result of severe consumption coagulopathy. During treatment with Acyclovir the bleeding situation was controlled by fibrinogen replacement. The infant survived and is under normal psychologic and motorical development now. The treatment result is taken for the good virostatic efficacy of Acyclovir. It inhibits the DNA polymerases and therefore the DNA replication within the herpes viruses selectively. This high degree of selectivity is caused by its selective penetration into the infected cells, its faster transformation by the viral thymidine kinase as well as by its stronger affinity for HSV coded polymerase in detail. The diagnosis had been confirmed by detection of herpes viruses within the blister fluid and cerebrospinal fluid as well as by serological findings.
