Oral manifestations in HIV-positive adults from Northern Thailand.

Eighty-seven HIV-infected patients in a provincial hospital in Northern Thailand were examined for oral manifestations of HIV disease and AIDS. The median age was 31.3 years. Seventy-four of the patients were women, 13 were men. 96.6% had a history of heterosexual transmission. Sixty-one patients were CDC-category A, 20 were category B and 6 were category C (AIDS). Thirty-eight percent of the patients revealed oral lesions; 23% had one oral lesion and 13.8% had two oral lesions. Common lesions were oral candidiasis (10.3% pseudomembranous candidiasis, 6.9% erythematous candidiasis and 3.4% both forms), oral hairy leukoplakia (11.5%) and exfoliative cheilitis (6.9%). Gingival linear erythema was seen in 8% of the patients; periodontal lesions and necrotising ulcerative gingivitis were not observed. Men were more commonly affected by oral manifestations than women (P < 0.004). The spectrum of oral lesions is comparable to other studies from the region, although most of these reported more men than women. Also, the degree of immunosuppression was more marked (AIDS).
