Subclinical human immunodeficiency virus-related changes in oral mucosa shown by image analysis of tongue smears.
There is evidence that certain lesions of the oral mucosa, such as hairy leukoplakia ( HL), in patients seropositive for human immunodeficiency virus correlate with the subsequent development of acquired immune deficiency syndrome. The authors suggest that HL is a final manifestation of alterations that gradually develop after HIV infection. To recognize inapparent early subclinical changes in oral mucosa, the authors applied methods of digital image analysis to investigate tongue smears from healthy control subjects and immunosuppressed patients after chemotherapy and HIV infection. Their studies concentrated on nuclear morphologic features and chromatin structure. The results obtained with a large set of subvisual parameters indicated significant differences in nuclear and chromatin features between the smear patterns of investigated groups. One important implication of these studies is that computerized image analysis of simply prepared tongue smears enables one to recognize subvisual HIV-related changes before clinical evidence of HL appears.[1]References
