The problem of fungus infections after liver transplantation was studied. In 100 consecutive recipients of orthotopic liver homografts there were 10 and 8 examples, respectively, of localized and disseminated infections caused by Candida species. Candidemia was demonstrated in 8 of these 18 patients. One patient who had a localized Candida infection also had disseminated cryptococcosis. An additional 31 patients were infested in that Candida could be cultured from sites where it is not normally found, such as the blood (8 examples), urine (8), ascitic fluid (8), and wounds (22). This exorbitant incidence of monilial infections and infestations was associated with a high frequency of complications involving the homograft as well as the hosts' gastrointestinal tract during the post-transplantation period. The yeasts found in blood, urine, ascitic fluid and elsewhere were thought to have originated from the gut. Ten of the 100 patients had aspergillosis which was localized in 7 instances and disseminated in 3. The lung was the most frequently affected organ. The fungus infections played a contributory role in the downhill course of our patients but in the event of death more fundamental and more frequent causes of failure were technical complications involving the homografts, difficulties in controlling rejection with reasonable immunosuppressive doses and bacterial sepsis. Suggestions have been made for the better control of fungal infections in liver recipients.

Deep visceral fungus infections, induced by occasional pathogens, have caused a new class of diseases, and occupy a more and more important place among the complications due to immunosuppressive agents. The experience of the Mycology Unit of the Pasteur Institute, where recent techniques of mycological and immunological diagnosis of these fungus infections are used, is reported here. 24 patients submitted to corticosteroids and other immunosuppressive treatments, including 6 renal transplants and one liver transplant, developed deep visceral infection with septicemia due to Candida, in a series of 106 cases of deep candidiasis due to massive antibiotic treatment diagnosed over the last few years. The mycological, immunological and therapeutic data obtained after treatment with amphotericin B and 5-fluorocytosine are reported here. 8 cases of meningeal, pulmonary and bony and cutaneous cryptococcosis, occurring after corticotherapy (6 cases), radiotherapy (1 case) and renal transplantation (one case), are presented together with the favourable results (6 cures out of 8) obtained with amphotericin B and 5-fluorocytosine, eight alone or in association. The authors also report 2 cases of aspergillosis, one in the lung, occurring in a case of renal transplantation who was given, at an early stage, amphotericin B and 5-fluorocytosine, thanks to rapid laboratory diagnosis, and another case in a heart transplant with pulmonary and cerebral localisations from which the patient died. The literature on these fungus infections, together with the mucormycoses, nocardioses and other fungus and antinomycosal complications are reported, together with parasitic infections the severity of which is emphasized in renal transplants, in particular P. carinii pneumonia, toxoplasmosis, strongyloidiasis and other parasitic diseases.

A retrospective review of 149 patients receiving 162 renal transplants showed that 83% of these patients developed one or more infections during a follow-up period averaging one year. In 32 (73%) of 44 deaths, infection was an important contributing cause. In only four (9%) of the deaths were the patients free of infection at the time of death. The Klebsiella-Enterobacter group was the most common agent causing pneumonitis and sepsis. Cryptococcus neoformans caused seven of 11 cases of meningitis. Pseudomonas was the most frequent agent associated with infections documented during postmortem examinations. In a short-term controlled study comparing daily and alternate daily therapy with prednisone, the alternate daily group had significantly (P less than .05) more infections per patient, especially in patients who had no evidence of rejection (P less than .025).

In a retrospective study covering the period January 1972 to June 1974, recovery rates of bacteria and of fungi were generally equivalent with tryptic soy broth, Thiol, thioglycolate, and Columbia broth media (all under vacuum with carbon dioxide and sodium polyanetholesulfonate). An additional biphasic medium consisting of brain heart infusion broth and a brain heart infusion agar slant, which was inoculated only where fungal sepsis was suspected clinically, yielded significantly higher recovery rates of fungi. There were 29 instances of cultures with fungi in both the biphasic and broth media, 80 instances of cultures with fungi only in the biphasic medium, and no instances of fungi only in the broth media. The isolates were as follows: Candida albicans, 74; C. parapsilosis, 20; C. tropicalis, 16; Torulopsis glabrata, 18; Torulopsis sp., 1; Cryptococcus neoformans, 12; C. laurentii, 2; and Histoplasma capsulatum, 16. Despite routine subcultures of the broth media to chocolate blood agar within 24 h of inoculation and after 5 days of incubation, detection of fungemia was significantly improved by the use of a biphasic medium.

From 10,351 blood cultures, we prospectively studied 1,000 BACTEC NR 660 aerobic resin blood culture bottles (26+ and Peds Plus) for patients suspected of having yeast septicemia to determine whether extended agitation and subculturing would increase the recovery of yeasts. Aerobic bottles were agitated continuously for 144 h. On day 7, 1,000 culture-negative aerobic bottles which had fungal blood culture requests were agitated for an additional 14 days. During this time they were subcultured twice and read twice by BACTEC NR 660. ON days 1 to 7, 81 bottles were cultured positive for yeasts from 36 patients, which included 44 isolates of Candida albicans, averaging 1.4 days to detection, and 12 isolates of Cryptococcus neoformans, averaging 3.8 days to detection. The average detection time for all yeasts was 2.2 days. On days 7 to 21, no yeasts were detected by BACTEC or recovered from the subcultures. We conclude that when continuously agitated for at least 5 full days (120 h), the BACTEC NR 660 aerobic resin bottles reliably isolate yeasts, and it is unnecessary to subculture or hold these bottles beyond 5 days. It also eliminates the need for an additional blood culture system for yeast detection, thus saving (i) confusion in the collection process, (ii) patients' blood and money, and (iii) laboratory technologists' time.

In this project, we examined the spectrum of AIDS-related conditions and variations in associated inpatient mortality for AIDS patients treated in a national sample of hospitals. We identified 10,538 adult discharges with a diagnosis indicating AIDS from 258 hospitals from a national sample of 438 acute-care hospitals with 6 million discharges in 1986-1987. Opportunistic and other infections occurred in 55.9 and 37.9%, respectively, of AIDS discharges, and inpatient fatality rates varied considerably depending on complication type(s) and comorbidities. Clinical conditions were more important predictors of inpatient death than demographic or treatment site characteristics. Among opportunistic infections, odds of inpatient death were significantly increased for progressive multifocal leukoencephalopathy (odds ratio [OR] = 2.8), Pneumocystis carinii pneumonia (OR = 2.4), cryptococcosis (OR = 1.6), atypical mycobacterial infections (OR = 1.6), and toxoplasmosis (OR = 1.3). Odds of inpatient death were also significantly increased by non-AIDS-defining infections causing septicemia (OR = 3.1) or CNS involvement (OR = 1.6) or pulmonary involvement (OR = 1.5). After controlling for clinical conditions, significant differences in odds of death persisted across regions, age, and ethnic groups. Increases in hospitals' AIDS treatment experience were associated with a significant decrease in odds of inpatient death. These analyses provide a national perspective on the diversity of AIDS-related clinical conditions and their relative effects on inpatient mortality.

Four patients with acute paracoccidioidomycosis, hypoalbuminemia, ascites and associated infections are reported. They have been admitted to hospital 35 times, 4 of them due to active paracoccidioidomycosis, 14 to associated infections, 14 to ascites, edema and diarrhoea and 3 to herniorrhaphy. Two of them recovered after sepsis and central nervous system, muscular and subcutaneous cryptococcosis. The remaining two died. One had infectious diarrhoea (S. flexneri), peritoneal tuberculosis and sepsis (S. epidermidis); the other had bacterial meningitis, erysipelas, beta-hemolytic Streptococcus sepsis and miliary tuberculosis. Their immunodeficiency was attributed to enteric protein loss and/or malabsorption and malnutrition and was recognized by reduced response to delayed hypersensitivity skin tests in four patients and hypogammaglobulinemia in three of them. The authors discuss the need for prospective studies to be carried out, aiming at the mechanisms involved in secondary infections. Alternatives for maintaining the patients' adequate nutritional state should be investigated, to guarantee proper immune response and thus the ability to control intervening infections in patients with juvenile paracoccidioidomycosis.

The clinical features and results of laboratory investigations of the first 19 Indian patients with AIDS seen in our hospital are presented. Weight loss, fever, and diarrhea were the most common symptoms. Tuberculosis (TB) was the most common secondary infectious disease; among 13 patients, seven had only pulmonary TB, five had pulmonary and extrapulmonary TB, and one had only extrapulmonary TB. Oropharyngeal candidiasis was found in 11 patients. Other secondary infections were predominantly by virulent bacteria. Opportunistic infections other than candidiasis were infrequent; one patient had cryptococcosis, two had symptomatic cryptosporidiosis, one had noncoagulase-positive staphylococcus septicemia, and one had cytomegalovirus retinitis. Reduced lymphocyte counts (particularly of the CD4 subset), anemia, hypoalbuminemia, hyperglobulinemia, and elevated liver enzyme levels were frequent laboratory findings. Six patients are under follow-up, two are lost to follow-up, and 11 have died. Lymphocyte counts less than 500/mm3 were only seen in those patients who subsequently died. Response to antituberculosis therapy was good in several patients. Thus, the clinical profile of Indian patients with AIDS is not different from the common picture of patients of low socioeconomic and poor hygienic standards; patients presented with TB, undernutrition, and multiple infections. Therefore, a large population of patients with AIDS in India will not be recognized unless they are tested for evidence of HIV infection.

In the immunocompromised patient, even mild forms of any combination of headache, meningismus, altered mental status, or focal neurologic signs should initiate an evaluation for possible CNS infection. The limited signs and symptoms of acute CNS infection are not due to specific organisms but to pathologic changes at the neuroanatomic site of infection. The initial clinical history, examination, laboratory, and neuroradiographic data will narrow the problem to one of several groups of agents, although it may not be possible to specify a single causative agent. It should be remembered that several concurrent infections (i.e., CMV and toxoplasmosis, aspergillosis, and bacterial sepsis) may be present. Thus, the clinician should rely on broad antibiotic coverage appropriate to the suspected causative agent or agents at the site of infection. It may be necessary to offer broad-spectrum antibiotic coverage for a CSF presentation that is subsequently found to result from a viral illness or from a noninfectious cause. However, one should avoid undertreating those infections for which specific therapy can be offered, and broad-spectrum treatment usually will not be regretted. Uncertainty in diagnosis following noninvasive procedures should lead to a brain biopsy. Although many of the infections discussed in this article have a poor prognosis, some of the most common pathogens, such as Cryptococcus, Listeria, and Toxoplasma, have effective specific therapies to which the patient should have access as rapidly as possible. The clinician who has successfully treated a patient with CNS infection should remain vigilant for late sequelae or recurrence of infection. Chronic treatment of some infections, such as toxoplasmosis or aspergillosis, may be necessary. The reintroduction of steroids for the treatment of an underlying cancer may reactivate previously treated disease, such as cryptococcosis, and periodic CSF surveillance is appropriate under these circumstances. Recurrence of the symptoms should raise the suspicion of recurrent or new infection, and the patient also should be evaluated with CT or MRI for the development of hydrocephalus or for new metastatic disease. In patients who have had varicella-zoster infection, postherpetic neuralgia and delayed arteritis may develop. Seizures, hearing loss, and neuropsychologic sequelae may follow any meningoencephalitis. The patient should always be reevaluated for the possibility of infection with a different opportunistic organism. CNS infections remain a major cause of morbidity and mortality in immunosuppressed patients with malignancies. In one series, 60% of such patients died as a result of their CNS infection, many at a time when the underlying disease had an otherwise good prognosis.(ABSTRACT TRUNCATED AT 400 WORDS)
