Skin and oral mucosal changes in patients infected with human immunodeficiency virus

Abstract

During a 6-month-period, 150 patients infected with Human Immunodeficiency Virus (HIV) were repeatedly examined by dermatologists and dentists for lesions of skin and oral mucosa. The most frequently encountered diseases were: oral hairy leukoplakia (21%), dermatophytosis (including tinea unguium/tinea pedis et inguinalis) (20%), seborrheic dermatitis (19%), viral infections (10%), oral candidiasis (7%), acne vulgaris (6%), and folliculitis (5%). A variety of other manifestations were seen, with frequencies less than 5%. Herpes zoster was seen in 3% of the patients, indicating a rate of 60/1,000 per annum. The presence of seborrheic dermatitis was statistically associated with low T-helper lymphocyte count. Patients with low T-helper lymphocyte count had on average twice as many mucocutaneous lesions as patients with a normal or moderately decreased count. Any one of the manifestations seborrheic dermatitis, oral candidiasis or oral hairy leukoplakia was associated with a greater average number of additional mucocutaneous changes than seen in patients exhibiting none of these three conditions. The high proportion of HIV-infected patients with cutaneous and oral lesions underlines the importance of referring the patients to dermatologists and dentists for examination. Prospective examinations of the study population remain to elucidate the prognostic significance of mucocutaneous manifestations of HIV-infected patients.
