Fifty immunocompromised children with varicella who exhibited no signs of dissemination were treated with intravenous acyclovir or placebo in a double-blind, randomized study. Twelve of 25 placebo recipients were withdrawn from treatment because of their deteriorating condition and were given open acyclovir therapy; only one of 25 recipients of acyclovir was similarly withdrawn (P less than .001). Among those patients who did not receive open treatment, acyclovir significantly reduced time to full crusting (P = .01). Overall, acyclovir, as judged by the physician, significantly improved the patients' condition.

The authors are reporting a typical case of congenital varicella syndrome following maternal varicella during the 17th week of pregnancy. At birth, the newborn showed necrotic bullae on the skin that healed later with characteristic scars. Other typical anomalies, i.e. hypoplastic limbs with muscular atrophy and clubfoot, intrauterine atrophy, dysphagia and anisocoria were also found. In view of the risk of serious malformations following intrauterine varicella infection attempts should be made to prevent varicella zoster virus infection during pregnancy.
