Candidiasis of the oropharynx and oesophagus is one of the most common problems encountered in patients with HIV disease. Fluconazole is a bis-triazole antifungal agent with a long serum half-life. Sixteen anti-HIV positive patients (15 haemophiliacs and one blood transfusion recipient) with a clinical diagnosis of oropharyngeal candidiasis were treated with 50 mg fluconazole daily for 14-28 days and then either 150 mg fluconazole or placebo weekly for 6 months in a prophylactic phase. Clinical cure occurred in all patients, and mycological cure occurred in 13/16 (81%) patients. In the prophylactic phase, there were 2/5 (40%) relapses in the placebo arm compared with 1/8 (12.5%) in the fluconazole arm, but this was not statistically significant by Fisher's one-sided exact test (P = 0.31). It is concluded that fluconazole is an effective treatment of oropharyngeal candidiasis and has potential for prophylactic use.

Mucosal candidiasis is one of the first opportunistic diseases in HIV-infected subjects. In order to understand the relationship between this disease and immunodeficiency to chemically defined, immunodominant Candida antigens, a mannoprotein fraction from C. albicans cell wall (GMP) was used to analyse proliferative and non-MHC-restricted cytotoxic responses of peripheral blood mononuclear cells (PBMC) from normal and HIV-infected subjects. In the former, GMP induced extensive blastogenesis, generation of powerful cytotoxicity against a tumour cell line (K562), and production of substantial amounts of interferon-gamma (IFN-gamma). Cultured PBMC from HIV-infected subjects manifested an early decreased ability for proliferative as well as differentiative cytotoxic responses to the candidal mannoproteins. This inability became clearly evident in subjects with stage III (CDC) of the disease, was total in CDC stage IV and occurred even in some subjects with a normal number of CD4+ cells. Low or absent response to GMP correlated with lack of response to tetanus toxoid. In contrast, both lymphoproliferative and cytotoxic responses to exogenous IL-2 was highly preserved at all stages of infection. The production of IFN-gamma in GMP-stimulated PBMC cultures critically fell to negligible values in most of the subjects in CDC stages II and III. Thus, the lowered or absent cell-mediated immune responses to candidal mannoprotein may be one factor to explain the early, elevated susceptibility of HIV-infected subjects to mucosal candidiasis. This study also shows that our mannoprotein preparation may be used as a probe to detect the overall efficiency of T cell responses in the above subjects.

Fluconazole is a recently approved agent for the treatment of certain fungal infections. Based on available studies, the drug is clearly effective in oropharyngeal candidiasis in immunosuppressed hosts. Current evidence suggests it may be more efficacious than other azole drugs for oropharyngeal disease. It is probably also effective in other infections due to Candida species, but controlled studies are lacking. Fluconazole is also efficacious in the treatment of cryptococcal meningitis, but recent reports question its use as initial therapy in HIV-infected patients with this illness. The drug, however, is clearly more effective than amphotericin B in the suppression of cryptococcal meningitis in AIDS patients and is the treatment of choice in this situation.

We studied the prevalence and severity of periodontal disease among 181 heterosexual men and women with AIDS. Included were 167 (92%) intravenous drug users (IVDU) and 14 sexual partners of persons at risk for AIDS. Periodontal disease was seen in 71 of 78 (91%) women compared to 75 of 103 (73%) men. Gingivitis was the most severe form of periodontal disease in 7 (9%) women and 15 (15%) men. Increased severity of periodontal disease was seen in women as compared with men (P less than .001); among subjects with periodontitis, 48 (75%) of 64 women had moderate to advanced disease compared to 32 (53%) of 60 men. For individuals with periodontitis, the extent of involvement was associated with severity; 90% of subjects with advanced periodontitis had all 4 quadrants affected. Concurrent oral manifestations of AIDS, including candidiasis, hairy leukoplakia, ulcers and Kaposi's sarcoma were present in 167 (92%) subjects. We conclude that HIV-associated gingivitis and HIV-associated periodontitis are common in heterosexual men and women with AIDS and are often accompanied by other oral manifestations of AIDS. The reason periodontal disease is more severe in women is not known. Clinicians should be aware that these disorders occur in heterosexuals as well as in homosexual men. Further study will be necessary to delineate the pathogenesis of these disorders.

Esophageal candidiasis, an opportunistic infection that generally occurs in the latest phases of infection due to the human immunodeficiency virus (HIV), is currently a diagnostic criterion for acquired immunodeficiency syndrome (AIDS). We recently treated one patient for esophageal candidiasis associated not with AIDS but with acute HIV infection. At follow-up 19 months later, he was well and had no symptoms related to infection with HIV. We reviewed nine previously reported cases of esophageal candidiasis associated with acute HIV infection. None of the patients involved had other predisposing illnesses or risk factors for candidiasis. The case described herein, together with those reviewed, supports a revision of the Centers for Disease Control's clinical definition of primary HIV infection to include esophageal candidiasis in the clinical spectrum. Moreover, the value of esophageal candidiasis as a diagnostic criterion for AIDS should be reassessed.

The acquired immunodeficiency syndrome (AIDS) was first diagnosed in burundi in 1983 when a large number of patients were registered with Kaposi's sarcoma, cryptococcal meningitis, and disseminated candidiasis. In the 1st phase of the disease the vi rus is dormant. In the 2nd phase seroconversion appears; and in the 3rd phase generalized adenopathy emerges. In the 4th phase the full-blown disease appears as a result of cellular immunity deficit with emaciation, fever, sweating, chronic diarrhea, asthenia, blood parameter changes (lymphopenia, thrombocytopenia, leukopenia, anemia, and specific immune disorders). The early phases can be diagnosed by serological tests. During 1989 a group of 155 patients with 1st signs of seropositivity were studied in the central hospital of Bugumbura. The available clinical diagnostic markers were: 56 cases of herpes, 26 cases of generalized adenopathy, 25 cases of inflammatory infiltration of paraganglionic zones, 13 abscesses and phlegmons, 8 cases of chronic proctitis, 8 prurigo cases, 7 cases of chronic pneumonia and bronchitis, 4 cases of paresis of the facial nerve, 4 cases of Kaposi's sarcoma, 2 cases of fresh syphilis, 2 cases of anemia, asthenia, dizziness, and weight loss. Tomo- and zonographical X-ray study of the thorax of 80 patients aged 20-65 (51 men and 29 women) was performed. In 62 patients changes in the lungs were evident. In 2 patients tuberculosis of the lungs was diagnosed: miliary TB in a 26-year woman and disseminated TB in a 31-year man. 2 chronic and 3 bronchial, and 10 interstitial pneumonia cases were diagnosed in 15 patients with average age of 30 years. 4 patients had peribronchial and pneumonic infiltrations. In a group of 45 patients magnified picture showed no deformation in the lungs; and only 5 had respiratory organ pathology. Interstitial pneumonia was the most often diagnosed ailment by X-ray inpatients infected with HIV.

One hundred and twenty-five HIV-infected patients, of whom 49 (39%) were at early stages of the infection (CDC-II & III) and 76 (61%) in CDC IV, were prospectively examined. In 100 (80%) one or more oral mucosal lesions were observed; candidiasis (51%) and hairy leukoplakia (43%) were the commonest. Erythematous candidiasis was more often seen (35%) than the pseudomembranous type (16%), and appeared with the higher values at early than later stages. The prevalence of hairy leukoplakia, oral hyperpigmentation and xerostomia were incremented in groups CDC-IV. Pseudomembranous candidiasis and exfoliative cheilitis increased significantly with severity of disease. Our study demonstrates that oral alterations associated to HIV are a frequent finding, both at early (76%) and late (83%) stages of the infection in Mexican patients.

Infection with the human immunodeficiency virus (HIV) may cause a variety of oral lesions, such as candidiasis, periodontal disease, hairy leukoplakia, Kaposi's sarcoma and a number of miscellaneous lesions and conditions. One hundred HIV-infected patients, including AIDS patients, referred to a University Hospital in Amsterdam, were examined orally. Most patients were initially seen by the Department of Internal Medicine, the oral examination by a well-trained dentist being part of the routine screening of all HIV-infected patients. In 80 per cent of all patients one or more HIV-related lesions of the oral mucosa was recorded. In 6 per cent of those patients the oral lesion was the first manifestation of the HIV infection. Hairy leukoplakia was observed in 15 per cent of all patients. Candidiasis proved to be the most common oral disease. In patients with full-blown AIDS the pseudomembranous form of candidiasis was the most common one, while in HIV-infected patients the erythematous type prevailed. These results emphasize the role of the dentist in making an early diagnosis of HIV infection.

Fluconazole, a new triazole derivative, was evaluated in a pilot study of 34 episodes of candidiasis in 24 children. All the patients had predisposing conditions, such as human immunodeficiency virus infection, cancer, organ or bone marrow transplantation, neonatal age and malnutrition, and obstructive uropathy. The drug was administered at 6 mg/kg (body weight) once daily either orally or intravenously. Two patients with fungemia due to Candida parapsilosis required an increased dosage of 12 mg/kg. Clinical and microbiological success was achieved in 30 of 34 cases (88%). Drug-related transaminase increases were observed in two cases (6%). Fluconazole may represent an effective alternative to amphotericin B in the treatment of candidiasis in children. Comparative trials are necessary to assess optimal dosages and efficacy.
