[Herpes zoster and post-herpetic neuralgia. Comparison between elderly patients and young adults treated with acyclovir].
Herpes zoster (HZ) is a common skin disease due to a virus identical to that responsible for chickenpox. In a variable number of cases neuritic pain persist after cutaneous healing. Aim of this investigation was to analyze zoster clinical evolution in 102 immunocompetent patients, subdivided by age (< 60 years and > or = 60 years) and sex, after treatment with acyclovir (4 g/die x 10 days). Signs and symptoms of the disease were evaluated, with particular attention to pain and the duration of post-herpetic neuralgia. Vescicular eruption was most frequently found in the thoraco-abdominal region and in the trigeminal one, with no significant differences among the subgroups. Two thirds of the subjects complained of pain and it was prevalent in female sex (84% of cases vs 53%, p < 0.01) but not in any age-class. After 1 months from the episode (and its pharmacological treatment), post-herpetic neuralgia was still present in about 20% of the patients, above all in those > or = 60 years; this last difference reached statistical significance after 6 months (9.7% vs 1.4% for subjects > or = 60 years and < 60 years respectively, p < 0.05). No patient showed any adverse pharmacological effect after treatment. We conclude that acyclovir is well accepted both in young and elderly immune-competent subjects suffering from HZ, but it necessitates further efficacy investigations in sight of its broader utilization.
