Eighty-four patients with fungemia were analyzed. Fungi had been isolated by culture of blood samples, including blood from the catheter for intravenous hyperalimentation, between 1986-1990. Candida albicans (39.3%), Candida parapsilosis (20.2%), Candida tropicalis (11.9%), Candida glabrata (10.7%), Candida guilliermondii (4.8%) and Trichosporon beigelii (4.8%) were the most frequently isolated fungal pathogens. Four patients' blood yielded two different fungal species. Fifty-nine cases were male, and 25 cases were female. Forty-six of the 84 patients died (54.8%), but there were no differences in the overall mortality rate as a function of the fungal species or sex. All patients had underlying diseases: solid cancer, 37 cases; cardiovascular diseases, 9 cases; gastrointestinal diseases excluding gastrointestinal cancer, 8 cases; central nervous system diseases, 7 cases; premature infants and congenital abnormality, 7 cases; leukemia, 6 cases and miscellaneous, 10 cases. Twenty-four of the 46 dead cases were autopsied, and eight cases showed systemic fungal lesions. However, in one case of pulmonary cryptococcosis and one case of pulmonary penicilliosis, there was no correlation between the isolation of C. glabrata by blood culture and the pathological findings. A fungus-positive blood culture was surmised to be a result of contamination of the sample in 33 cases, and the mortality rate for those cases was 72.2% (24 cases). For 6 of the corpses, fungal lesions observed at autopsy were compatible with the types of lesions found by the fungi which had been isolated before death. Removal of the catheter reduced the mortality rate to 41.7%. Fungal endophthalmitis was diagnosed in six cases.(ABSTRACT TRUNCATED AT 250 WORDS)

Glucose tolerance factor (GTF), the biologically active form of Cr3+, has been ascribed a role in the potentiation of insulin action and glucose homeostasis. The present study investigated the effects of dietary supplementation with GTF-rich brewer's yeast (Saccharomyces cerevisiae) or GTF-deprived Torula yeast (Torulaspora delbrueckii) in genetically diabetic C57BL/KsJ db/db mice. At 15 weeks of age, db/db mice exhibited increased body weight, hyperphagia, hyperglycaemia, hyperinsulinaemia and increased glycosylated haemoglobins compared with control (+/+) mice. During 56 days consumption of diets supplemented with 50g brewer's yeast or Torula yeast per kg, body weights of both groups of db/db mice decreased by 35%, in association with 1.2-1.7 fold increases of food intake, plasma glucose, glycosylated haemoglobins and an 83% decrease of plasma insulin. With the exception of slightly decreased weight loss, addition of brewer's yeast as opposed to Torula yeast did not affect tissue or plasma chromium nor ameliorate any of the parameters monitored including glucose tolerance and insulin sensitivity at 52-54 days. These findings do not support the contention that the glucose intolerance of genetically diabetic C57BL/KsJ db/db mice partly reflects GTF deficiency.

With the increased number of immunocompromised patients there has been a concomitant increase in patient morbidity and mortality due to fungi. The etiologic microorganisms vary depending upon the type of immune dysfunction. Patients with malignancies and chemotherapy-induced neutropenia commonly are infected with Candida and Aspergillus. Other ubiquitous fungi such as Rhizopus, Fusarium, and Trichosporon are more frequently implicated as agents of disease in these patients. Patients with cell-mediated immune dysfunction such as acquired immune deficiency syndrome (AIDS) are susceptible to mucocutaneous candidiasis and pulmonary and disseminated cryptococcosis. Histoplasmosis and coccidioidomycosis have been particularly lethal infections in AIDS patients. Contributing factors such as broad-spectrum antibiotic use, intravenous catheterization, malnutrition, hyperalimentation, multiple surgical procedures and/or trauma, and steroids used either singly or in combination may also predispose patients to invasive fungal disease. Definitive diagnosis is often difficult to establish and usually requires invasive biopsy. Delay of culture results due to the time required to process specimens and to allow the fungus to grow also contributes to the poor results of therapy. Biopsy of skin lesions represents a useful technique for making a diagnosis. Recent advances in antifungal therapeutics promise to change the current approach to treatment for several of the mycoses. The availability of new oral azoles with spectra of activity that include aspergillosis and cryptococcosis, which currently require treatment with parenteral amphotericin B, may prove practical for prolonged oral therapy of otherwise lethal mycoses.
