In our study 77 AIDS patients suffering from oral and/or esophageal candidiasis were evaluated: 38 received fluconazole, 39 ketoconazole. We analyzed the rates of clinical and mycological responses, relapses and toxicities. In vitro susceptibility tests for both antifungal drugs were performed by evaluating their Minimal Inhibitory Concentrations (MICs). The azole drugs investigated show a good activity in the treatment of oropharyngeal and esophageal candidiasis also in advanced stages of HIV infection. Clinical cure or improvement were achieved in 29 (76.3%) and 31 (79.4%) of the patients treated with fluconazole or ketoconazole respectively. Clinical or laboratory adverse experiences related to fluconazole were seen in 7 (21.2%) patients while ketoconazole provoked adverse experiences in 9 (26.4%) patients. In vitro susceptibility tests, if repeated more than once, both in primary infection and relapses, could be important to demonstrate a probable sensitivity change or resistance of the tested strains.

We define the clinical importance of cytomegalovirus (CMV) in the natural history of patients with concomitant candida and CMV infection of the esophagus. Prospective evaluation was made of patients with Candida and CMV esophagitis enrolled in a trial of antifungal therapy for Candida esophagitis. Retrospective review was also made of the course of patients who had been found to have both Candida and CMV infection during a previous prospective endoscopic study investigating the etiology of esophageal symptoms in HIV infection. Ten (21%) of 48 patients with Candida esophagitis in the prospective study had evidence of esophageal CMV (nine by culture, one by histology). One died after 4 weeks of therapy, with minimal retrosternal pain. None of the remaining nine had any symptoms or gross CMV esophagitis after antifungal therapy. Thirteen other patients with CMV and Candida were included in the retrospective review (mean follow-up of 8 months). Eight patients received antifungal therapy alone: six (CMV determined by histology in three and by culture in three) had symptomatic resolution; one (CMV by culture) had ongoing symptoms, and a second endoscopy showed an esophageal ulcer due to CMV (histology and culture); and one had ongoing symptoms but a negative repeat endoscopy. Two died without receiving treatment, and three were treated with antifungal and anti-CMV therapy together because of concurrent CMV retinitis (esophageal symptoms resolved in all three). Thus, CMV was of clinical importance in the esophagus in only one of 18 patients with CMV and Candida who received antifungal therapy alone.(ABSTRACT TRUNCATED AT 250 WORDS)

435 hemophiliacs are usually being attended in the La Paz hemophilia Center (Madrid, Spain). 257 (59%) of these patients have been infected by the human immunodeficiency virus (HIV-1) because of human plasma derivate substitution therapy. The infection has been more frequent among the severely affected patients and among the most treated patients. 82% of the infected patients are between 14 and 40 years old. By December 1991, 95 (37%) of 257 seropositive patients have developed full-blown AIDS. The most frequent opportunistic infection they had suffered was esophageal candidiasis. Looking for an evolution marker, we can point that the patients older than 35 years with CD4 levels below 200/mm3 had the worst prognosis. There was no difference in the evolution among the patients aged below 17 and those aged between 17 and 35 years. The amount of concentrate used between 1980 and 1984 did not hold any relation to the evolution. 49 patients (51%) of the 95 suffering from AIDS had died by December 1991. The evolution to the death was unrelated to the patient age, CD4 lymphocyte levels, and amount of substitution therapy. In our opinion, the most valuable marker could be the kind of opportunistic infection or tumor the patient suffers from. Finally, Retrovir has demonstrated to be useful in increasing the survival rate of the patients, but after 36 months of treatment, only 33% of those AIDS patients who began taking it remained alive. Retrovir was also used in asymptomatic patients, and during an average period of time of 15 months, a lesser bone marrow toxicity and a stabilization in CD4 lymphocyte levels could be observed, but this was unable to modify the disease progression in those patients who presented circulating p24 antigen.

The medical records of 114 consecutive HIV-infected patients with oropharyngeal and esophageal candidiasis, in whom esophagoscopy was performed, were reviewed. Esophageal candidiasis and isolated oral candidiasis were found in 75% and 25% of patients, respectively. Esophageal candidiasis was the AIDS-defining illness in 65 patients and dysphagia was the commonest symptom, but asymptomatic Candida esophagitis was observed in 43% of them. Symptoms were present in six patients with oropharyngeal candidiasis; three of them had a normal esophagoscopy and the other three had acute nonfungal esophagitis. Invasive fungal esophagitis was confirmed by biopsy in 47/74 patients (64%). The patients with esophageal candidiasis had lower CD4+ cell counts (129/microliter) and CD4:CD8 ratios (0.23) than those with oropharyngeal candidiasis (CD4 179/microliter; CD4:CD8 0.35). Thirty-six patients with esophageal candidiasis were treated with fluconazole, 100 mg/daily, for 28 days, and another 34 patients received the same dose for 10 days. A similar efficacy was seen in both regimens, but a higher incidence of oropharyngeal fungal colonization and liver dysfunction was observed in the longer therapy (p < 0.001). We conclude that asymptomatic C. esophagitis is common in HIV-infected patients. Patients with oropharyngeal candidiasis may complain of esophageal symptoms; it could be due to superficial C. infection or another not-identified opportunistic infection. More severe immunologic impairment was required to develop esophageal candidiasis than oropharyngeal candidiasis. A short course of 10 days of fluconazole therapy could be the standard regimen for the treatment of C. esophagitis in AIDS.

The study of the clinical manifestations, progression, and outcome of human immunodeficiency virus (HIV) infection in women has begun in earnest. AIDS-defining diseases that are more common in women than in men include wasting syndrome, esophageal candidiasis, and herpes simplex virus disease, whereas Kaposi's sarcoma is rare. Non-AIDS-defining gynecological conditions such as vaginal candida infections and cervical pathology are prevalent among women at all stages of HIV infection. Associations have been documented between the presence of human papillomavirus, lower genital tract neoplasia, and HIV-related immunosuppression. Pregnancy has not been confirmed to have an effect on the clinical progression of HIV disease in women incremental to the effect of time. Differential access and utilization of therapeutic interventions appear to account for much of the reported gender discrepancy in survival. Well designed epidemiological and clinical studies will help further scientific knowledge leading to early diagnosis, appropriate treatment, and timely prevention of the manifestations of HIV disease in women.

Esophageal disease is a common complication and cause of morbidity in patients with human immunodeficiency virus (HIV) infection. Opportunistic esophageal diseases may occur in patients with long-standing infection or may be the initial manifestation of HIV disease. Although a variety of both opportunistic and nonopportunistic disorders result in esophageal disease in this population, candidal esophagitis is the most common cause of symptomatic disease. Ulcerative esophagitis resulting from cytomegalovirus and idiopathic esophageal ulceration constitute the next most important etiologies. In contrast to other immunocompromised hosts, herpes simplex virus esophagitis appears to be relatively uncommon. Multiple simultaneously discovered esophageal disorders have been documented in up to 50% of patients. Opportunistic neoplasms are an infrequent cause of symptomatic disease. Candidal esophagitis may present with either dysphagia or odynophagia, and oropharyngeal candidiasis is usually present at the time of diagnosis. In contrast, ulcerative esophagitis is usually first manifested by moderate to severe odynophagia. Barium esophagography and upper endoscopy are the most commonly employed diagnostic modalities for the evaluation of the symptomatic patient. Although barium esophagography may identify specific abnormalities, this procedure appears to be relatively insensitive for the detection of mild candidal disease as well as nondiagnostic for ulcerative lesions when compared with endoscopy. In the HIV-infected patient with new-onset esophageal symptoms, an empiric trial of a systemically acting oral antifungal agent should probably be the initial management strategy. If the patient does not respond to standard therapy within 1 to 2 weeks, an endoscopic evaluation appears to be the most cost-effective diagnostic test given the diversity of potential disorders, the possibility of one or more co-pathogens or diseases, the potential for an immediate diagnosis, and the availability of mucosal biopsy to make a definite diagnosis of ulcerative or mass lesions. Given the presently available therapy for these diverse processes, establishing a definitive diagnosis in the symptomatic patient not responsive to empiric antifungal therapy is warranted.

In order to evaluate the efficacy of 200 mg single weekly dose of fluconazole in the secondary prophylaxis of esophageal candidiasis in AIDS, 18 patients who had an endoscopic confirmation of cure after an esophageal candidiasis, were studied. Mean follow up period was 12.5 months (limit: 1.5-18) and 11 patients completed prophylaxis for 11.2 months (limit: 2-18). Fluconazole was interrupted in the 7 remaining patients due to different reasons after 10 months and they were followed for 3.2 more months (limit: 1-5). Ten patients relapsed with a total of 17 episodes (7 oropharyngeal and 10 esophageal). Only 4 of the 18 patients (22%) relapsed while on correct prophylactic treatment. On the other hand, 6 out of 7 patients (86%) relapsed in the absence of fluconazole (p less than 0.001). The relapse incidence rate in both groups was 0.09 and 1.46/100 patients/day respectively (p less than 0.001) and its appearance was much earlier (1.3 versus 9.5 months) in patients not receiving prophylaxis. Relapses did not correlate with CD4 cell level, HIV-Ag level, opportunistic infections, use of other drugs or mortality. Fluconazole was interrupted in 3 patients because of alternations in liver enzymes although its relationship with the drug was not confirmed. These results indicate that the administration of Fluconazole 200 mg/week in a single dose is very efficiency in secondary prophylaxis of esophageal candidiasis in AIDS patients.

In 1987, data from the Centers for Disease Control AIDS data base indicated a 50% prevalence of oropharyngeal Candida infection, a 10% rate of esophageal infection, and .5% rate of bronchopulmonary infection among AIDS patients. Candida-positive blood cultures were found in 13 of 903 AIDS patients, and disseminated Candida infection was ascertained in 11 of 101 post mortem examinations of AIDS victims. 5 of 12 patients with oral Candida infection progressed to AIDS within a 42-week investigation as opposed to only 1 of 17 patients without Candida. In the former group, CD4 counts and CD4/CD8 ratios were also significantly lower. Most infections were caused by Candida albicans. Genital Candida occurs in 5-20% of women in reproductive age. In a study of 66 HIV-infected women Candida vaginitis preceded oral Candida infections which preceded Candida esophagitis. 33 women had vaginal infection, 25 had oral Candida, and 9 had esophageal infection with reduced CD4 counts. Infections of the oropharynx and the vagina are reduced CD4 counts. Infections of the oropharynx and the vagina are treated with amphotericin B, nystatin, miconazole, and clotrimazole. Systemically effective compounds include ketoconazole, itraconazole, and fluconazole, although interactions with rifampicin, phenobarbital, and phenytoin used in HIV treatment occur. Fluconazole is contraindicated in C. glabrata and C. krusei infections as it selects for azole-resistant Candida strains. Iv amphotericin B and fluconazole are used in serious infections when oral treatment is ineffective.

The location of tuberculosis (TB) early in the course of HIV-induced immunosuppression was located, and an attempt was made to determine the correlation between the degree of immune suppression and prognostic variables to stratify the risk for dissemination of TB in HIV-infected patients. Clinical and laboratory characteristics were reviewed in 73 HIV-infected patients with TB admitted between 1984 and 1990. The presence of Mycobacterium tuberculosis was investigated in different clinical samples to verify the diagnostic yield of different sources. TB was extrapulmonary in 46.6 per cent of patients in whom it was their first opportunistic infection, and in 46.7 per cent of patients with previously diagnosed AIDS (p = NS). TB was frequently associated with other opportunistic infections, particularly oesophageal candidiasis (p = 0.006). Patients with localized extrapulmonary or disseminated TB presented more often with cytopenias, hypoalbuminaemia and oral thrush. The existence of extrapulmonary TB or another opportunistic coinfection allowed AIDS to be diagnosed in the same admission in 30 patients and a mean of 8.4 months later in another eight. Extrapulmonary TB was found to be as common in early HIV infection as in patients with established AIDS. Haematological derangements were common in these patients, and cytopenias, hypoalbuminaemia and oral thrush were useful predictors of TB dissemination. The location of TB and its dissemination were not significantly linked to a more advanced CDC stage of HIV infection or a more profound fall in CD4 count.(ABSTRACT TRUNCATED AT 250 WORDS)

To determine the efficacy and toxicity of two systemically active antifungal agents in the treatment of buccal and oesophageal candidiasis 111 HIV-infected patients with microscopically-confirmed candidiasis were randomized to receive either 200 mg itraconazole once a day or 200 mg ketoconazole twice a day for 28 days in a double blind study. After 1 week of treatment, 75 and 82% of the patients on itraconazole and ketoconazole, respectively, had responded clinically. After 4 weeks of treatment, this had risen to 93% in each group. One patient discontinued itraconozole because of toxicity (rash), five patients discontinued ketaconazole (two nausea, two hepatotoxicity and one rash). Despite successful clinical and mycological clearance, 80% patients had a further episode of candidosis within the next 3 months.
