Comparative trial of acyclovir and vidarabine in disseminated varicella-zoster virus infections in immunocompromised patients.
A comparative assessment of vidarabine and acyclovir in the treatment of varicella and disseminated zoster in immunosuppressed patients was undertaken. Thirty-eight immunosuppressed patients with varicella (N = 18) or disseminated zoster (N = 20) were treated intravenously with 10 mg/kg/day of vidarabine or 30 mg/kg/day of acyclovir for 5 days according to a preestablished code within each diagnosis group--varicella and disseminated zoster. Two deaths, although not directly related to VZV infection, were observed in the vidarabine-treated varicella group. The times to cessation of formation of new lesions and to the disappearance of fever were similar for vidarabine and acyclovir in each group. In the varicella group, VZV was isolated on day 5 in four out of five vidarabine patients versus one out of five acyclovir patients. No severe adverse effects were observed with either drug. Neutropenia present in patients of both drug groups was transitory and most often related to previous cytolytic chemotherapy. These data suggest that either vidarabine or acyclovir could be used in the treatment of severe VZV infections in immunosuppressed patients, although a larger number of patients would be required for definitive conclusion. Because of the large amount of solute required for vidarabine administration, acyclovir may be preferred when the risk of cardiorespiratory failure is high.
Atracurium in patients with renal failure. Clinical trial of a new neuromuscular blocker.
Atracurium was given to 30 patients with terminal chronic renal insufficiency, in two regimens. Group I (20 patients) received a single dose of 0.6 mg kg-1 and group II (10 patients), received one or several injections of 0.2 mg kg-1. Tracheal intubation was performed with ease in all patients 3 min after the injection of atracurium. A supramaximal stimulus was applied to the ulnar nerve at wrist level, and thumb adduction force was recorded. Muscular blockade was 100% in 29/30 patients and 95% in one. Mean time between atracurium injection and reappearance of 25% of the initial muscular power (HT25) was 49 min. The recovery time index (IR25-75) was 12 min and did not increase after re-injection. No side-effects were observed and no significant differences in any of the measurements made were seen between the two groups.
