Introduction: Herpes zoster is a world-wide disease of older age commonly presenting with preherpetic pain. The aim of the study was to determine clinical characteristics of preherpetic neuralgia and its influence on occurrence of postherpetic neuralgia.
Material and methods: A prospective, controlled trial included 88 patients with preherpetic neuralgia. 44 herpes zoster patients without preherpetic neuralgia were included in the control group. All of them were clinically followed-up for three months after complete healing of skin lesions.
Results: Older age (> 60 years) was significantly predominant (59.1%) compared with other age groups (p < 0.01) as well as female sex (59.9%) compared with the male sex (p < 0.01). There was no significant predominance of any type of preherpetic neuralgia (stabbing, burning, itching, dull pain). More intense preherpetic pain (reported as “severe” and “moderate”) was established more often than mild pain. The mean duration of preherpetic pain was 4.4 days (ranged between 1-20 days). Postherpetic neuralgia developed in 36/88 patients with preherpetic neuralgia (affecting predominantly older than 50 years of age–31/36), but there was no significant difference in proportion of postherpetic neuralgia (PHN) according to those without preherpetic neuralgia.
Discussion and conclusion: People older than 60 years are the most common age group among herpes zoster patients suffering from preherpetic neuralgia. Sex distribution of patients with preherpetic pain reveals highly significant predominance of female sex. Opposite to some other authors’ reports, preherpetic neuralgia and its severity have not been proven as risk factors for postherpetic neuralgia in patients involved in our trial.
