Nasal mucosal cell alterations in HIV-infected patients.
Patients with HIV infection often have nasopharyngeal symptoms related to inflammatory or infectious diseases of the upper respiratory tract. In this study, we examined specific nasal mucosal cytologic alterations in adult patients with HIV infection for associations with nasopharyngeal symptoms and other clinical parameters. Mucosal cytology was obtained in 62 patients from an urban HIV clinic using a plastic curettelike probe. The quantities of goblet cells, vacuolated cells, and leukocytes were determined and analyzed for associations with various clinical aspects of these patients and specifically with the presence or absence of prolonged (> 2-week duration) nasopharyngeal symptoms. Goblet cell, but not vacuolated cell, increases were observed in samples in which nasal eosinophilia was present and in samples obtained from April to October without specific associations with nasopharyngeal symptoms or histories of atopic disease. A history of allergic rhinitis or recent upper respiratory infection was significantly associated with increased proportions and total numbers of epithelial cells that showed vacuolization. In patients with prolonged nasopharyngeal symptoms, significantly higher numbers of nasal leukocytes were observed but higher proportions of vacuolated cells were not. Scores of tests for abnormal physical findings in the nose were higher for patients with prolonged nasopharyngeal symptoms than for those without. Peripheral blood CD4 concentrations, gender, nasal substance abuse history, and other comorbidities did not influence either vacuolated cell or goblet cell quantities. These data show that prolonged nasopharyngeal symptoms in HIV infection are associated with a certain nasal cellular pattern. It is conceivable that this pattern relates to recurrent or prolonged nasal inflammation secondary to upper respiratory infection.
