Cardiology, Objective. Varicella-zoster
virus has been reported to produce serious, often
life-threatening, disease in immunosuppressed patients with a variety
of diagnoses. The impact of this virus on the young child after heart
transplantation has not been reported.
Methods. We reviewed the charts of 28 children who were
<10 years of age at heart transplantation and had at least 1 year of
follow-up. The median follow-up period was 7 years (1.4-13.0 years).
All were seronegative for varicella-zoster virus before
transplantation. Fourteen (50%) developed varicella at a median time
posttransplantation of 3.3 years. The first 7 were admitted for
intravenous acyclovir for 3 days followed by oral
acyclovir for 7 days. The last 7 were treated as
outpatients with oral valacyclovir for 7 days (n = 6) or with oral acyclovir for 10 days
(n = 1).
Results. Intravenous and oral regimens both were well
tolerated and were without complications. No patient was receiving
steroids at the time that they developed their initial episode of
varicella. One patient was receiving steroids for therapy of
posttransplantation lymphoproliferative disease when she developed
recurrent varicella or generalized zoster. No episodes of rejection
were attributed to the varicella-zoster virus infection. There were no
episodes of localized zoster. All patients experienced seroconversion
from undetectable to detectable antibody titers early after varicella, and 12 of the 14 patients continued to have persistent detectable titers in late follow-up. Two of the 14 who received chemotherapy or
enhanced immunosuppression after retransplantation transiently lost
detectable varicella-zoster virus antibodies but currently have
detectable titers.
Conclusions. Primary varicella-zoster infection was well
tolerated in our young pediatric heart transplant recipients, with no
serious complications. We now reserve inpatient/intravenous therapy for those who are unable to tolerate oral medications or those who are
receiving enhanced immunosuppression.
