Patients with AIDS but without pneumocystis carinii pneumonia, patients with advanced AIDS-related complex (ARC), and asymptomatic patients with less than 200 CD4-positive lymphocytes/mm3 were randomized to one of two groups: group I: Inhalation of 300 mg of pentamidine every 28 days; group II: Inhalation of placebo (300 mg of Na isethionate) every 28 days. From May to November 28, 1989, 160 patients have entered the trial. Inhalations were well tolerated, with only a 6% use of bronchodilators and a 15% incidence of cough. Until now five patients died, none of them drug related. So far, six patients have developed pneumocystis carinii pneumonia; four of these were on pentamidine, and two on placebo. Five of the six cases occurred before the second inhalation. Recruitment will continue until 250 patients are enrolled.

Although many of the pulmonary manifestations of tuberculosis in the acquired immunodeficiency syndrome (AIDS) are well known, endobronchial involvement has not been previously described. We report the clinical, roentgenographic, and bronchoscopic features of three patients with endobronchial tuberculosis and AIDS. All of the patients had nonspecific symptoms of fever and cough; however, none exhibited the classic findings of dyspnea, wheezing, or hemoptysis. Smears of sputum were nondiagnostic. The chest x-ray film revealed mediastinal adenopathy in two patients and a lower lobe consolidation in the third; all had small ipsilateral pleural effusions. Endobronchial lesions were white or pink exophytic masses obstructing the airways, mimicking bronchogenic carcinoma. Areas of "classic" primary tuberculosis were seen in two of the patients. Despite ongoing clinical and roentgenographic deterioration, all patients responded well to antituberculosis medications. Given the frequency of tuberculosis in patients with AIDS and AIDS-related complex, one should maintain a high index of suspicion for involvement of the tracheobronchial tree, so as to avoid a delay in diagnosis and resultant increased morbidity and mortality.

We observed 276 HIV-infected patients to determine the frequency, degree, and clinical presentation of the lymphocytic alveolitis in different stages of HIV disease, and also to identify the lymphocyte subsets involved. In 154 patients with proved lung infections or tumors (group A), bronchoalveolar lavage fluid showed lymphocytosis in 78 percent of cases. In 122 subjects (31 AIDS and 91 HIV-infected non-AIDS patients) without evidence of lung tumor or infection (group B), lymphocytic alveolitis was seen in 72 percent of cases. In 61 of 88 (69 percent) group B lymphocytic patients, we observed respiratory symptoms or diffuse interstitial opacities; however, we also observed such alveolitis in 27 of 46 (59 percent) group B patients free of respiratory symptoms and abnormality of chest x-ray film. This alveolitis was seen not only in AIDS or ARC patients but also at earlier stages of HIV infection. T-lymphocyte analysis showed a large majority (40 to 93 percent) of CD8 positive lymphocytes in the 37 patients tested. A dual fluorescence analysis revealed, in 18 subjects, that those cells were phenotypically cytotoxic (CD8 + D44 +). These findings suggest that, regardless of HIV-infection stages and of opportunistic lung infections, a CD8-positive T-lymphocyte alveolitis may be present in HIV-infected patients and could be responsible for cough, dyspnea, interstitial pneumonitis, and abnormalities of pulmonary function tests.

Three patients with the acquired immune deficiency syndrome (AIDS) or AIDS-related complex and lymphocytic interstitial pneumonia are reported. All patients presented with progressive dyspnea, nonproductive cough, fever, anorexia, weight loss, and arterial hypoxemia. Chest roentgenograms exhibited bilateral diffuse reticular-nodular densities. The diagnosis of lymphocytic interstitial pneumonia was made by fiberoptic bronchoscopy or open lung biopsy. Two patients were treated with corticosteroids, with significant improvement. The third patient died of pneumonia due to Pneumocystis carinii six months after the diagnosis of lymphocytic interstitial pneumonia was established. Serum antibodies to human immunodeficiency virus (HIV) were demonstrable in the two patients in whom the test was performed. Lymphocytic interstitial pneumonia is probably another pulmonary manifestation of AIDS or AIDS-related complex. Although the clinical presentation may be identical to the more common opportunistic infections, the treatment differs, and the prognosis may be better.

Acquired immunodeficiency syndrome (AIDS) is reviewed for dental practitioners, with an emphasis on oral findings; the clinical course, diagnosis, reporting, treatment, prognosis, transmission, and epidemiology are also covered. HIV infection has an incubation period that may be associated with glandular fever, a prodrome called AIDS-Related Complex (ARC) characterized by lymphadenopathy, low fever, weight loss, night sweats, diarrhea, oral candidosis, nonproductive cough and recurrent infections. AIDS is characterized by opportunistic infections. Over 50% present with pneumocystis carinii pneumonia, 21% with Kaposi's sarcoma, and 6% have both. The AIDS virus causes direct neurological symptoms in some cases. Oral candidosis (thrush) in a young male without a local cause such as xerostomia or immune suppression is strongly suggestive of AIDS. Other oral manifestations are severe herpes simplex, varicella-zoster, Epstein-Barr virus, cytomegalovirus, venereal warts, aphthous ulceration, mycobacterial oral ulcers, oral histoplasmosis, sinusitis and osteomyelitis of the jaw. Hairy leukoplakia, usually seen on the lateral border of the tongue, is probably caused by Epstein-Barr virus. Kaposi's sarcoma, an endothelial cell tumor, is characteristic of AIDS, and in 50% of patients is oral or perioral. Cervical lymph node enlargement will be seen in those with ARC as well as AIDS. No guidelines have been issued by the Department of Health and Social Security for dental surgeons in the UK for reporting AIDS cases. Although HIV virions have been isolated from saliva, there are no known incidents of transmission via saliva. HIV is less likely to be transmitted by needle stick injuries than, for example hepatitis B (25% risk), especially if the blood is from a carrier rather than a full blown AIDS case.
