A 5 - Year Clinical Study on Herpes Zoster: 1990 - 1994 / 대한피부과학회지

ABSTRACT

BACKGROUND: Herpes zoster is an important and troublesome disease. OBJECTIVE: The purpose of this study was the elucidation of the epidemiological and clinical characteristics of herpes zoster through patient assessrnent. METHODS: During a 5- Year period, January 1990 to December 1994, 215 patients with herpes zoster were assessed with regard to annual and monthly frequency in occurrence, age and gender incidence. Associated conditions, dermatomic distributions, the relationship of onset of pain and skin lesions, Multi-CMI test and complications were also evaluated. RESULTS: 1. The annual freguency of herpes zoster ranged from 0.88% to 1.78% (mean 1.23%) during the 5-year period. The highest number of herpes zoster patients was observed in winter (p<0.001) especially in January. 2. Herpes zoster was found to most frequently afflict persons aged 50-59 (27.9%). 71% of the patients were over 40 years of age. 3. In 76 patients (41.8%), neuralgia occurred several days (4 days mean) before the development of skin lesions. In 92 patients (50.5%), pain and skin lesions developed simultaneously while skin lesion development occurred before the onset of pain in 14 patients (7.7%). 4. Among the patients, 42.8% had associated conditions such as diabetes mellitus, hypertension, pulmonary tuberculosis, liver diseases, peptic ulcer, hypothyroidism, pharyngitis, fracture, etc. 5. The dermatomic invclvement of herpes zoster patients having one dermatome was most frequent in thoracic dermatome ca. es (52.6%). Others included cervical (16.7%), trigeminal (11.6%), sacral (6. 0%), lumbar (4.2%), facial (0.5%). Cases having two different dermatomes constituted 8.4%. 6. The most common complication of herpes zoster was postherpetic neuralgia although instance of ophthalmologic compiications, secondary bacterial infection, scar formation, Ramsay-Hunt syndrome, keloid formation, and urinary difficulty were also documented. 7. Multi-CMI (Cell-mediated immunity) tests were done on 88 herpes zoster patients. Thirteen of them (14.8%) were found to have comparatively depressed scores. Ten of the 79 single dermatome involvement patients (12.7%) and three of the 9 two dermatome involvement patients (33.3%) exhibited similar scores. CONCLUSION: These results are in accordance with those of previous reports with the exception of the higher incidence ot two different dermatome involvements and seasonal variation.
