Intravenous Immunoglobulin and Intravenous Acyclovir as an Alternative Therapy to Varicella Zoster Immunoglobulin in the Prevention of Serious Complications of Neonatal Varicella.

ABSTRACT

Neonatal varicella, arising from maternal infection with the varicella-zoster virus (VZV), is a rare but potentially severe condition with diverse clinical presentations. This case report highlights an instance where the mother developed a maculopapular rash seven days before delivery, indicating a possible transmission of VZV to the neonate. The patient's family history included recent diagnoses of herpes zoster and varicella among household members. On the second day of life, the newborn developed a discrete vesicular rash on an erythematous background, affecting the trunk and neck. Due to the unavailability of varicella zoster immunoglobulin (VZIG), intravenous immunoglobulin (IVIG) was administered along with a seven-day course of intravenous acyclovir. Despite the absence of VZIG, the combined treatment with IVIG and acyclovir proved effective in resolving the rash by the sixth day of life, without any ensuing complications. This case underscores the challenges of managing neonatal varicella in resource-limited settings and suggests that combination therapy may not prevent the occurrence of neonatal varicella but can mitigate serious complications and expedite clinical recovery.
