Among patients examined at the Central Laboratory of Yokohama City University Hospital over the 25 years from 1965 to 1989, those whose clinical samples showed Cryptococcus were studied in greater detail. The following findings were obtained. Of 16 patients who were found to have cryptococcosis, 14 (87.5%) were treated at the department of internal medicine, and one each at the departments of neurosurgery and dermatology. A study of these patients in terms of clinical type revealed 10 patients (62.5%) with meningitis, two with pneumonia and one with sepsis. The remaining three patients had complicated diseases: meningitis with sepsis, pneumonia with cutaneous cryptococcosis, or pleuritis with sepsis. Underlying disease, including liver cirrhosis, leukemia, multiple myeloma, malignant lymphoma and collagen disease, was found in 6 patients (37.5%), who were all from the department of internal medicine. All patients but one were given antimycotic agents. They were treated by a combination therapy except for three patients who received single amphotericin B (AMPH) therapy. The most frequent combination was AMPH + 5-flucytosine (5-FC), which was found in 7 cases. Seven patients (43.4%) died, three males and four females. Analysis of these cases in terms of clinical type revealed meningitis in four, and pneumonia, sepsis, or pleuritis complicated with sepsis in the remaining three patients. Four patients (57.1%) had underlying diseases. In addition, eleven strains isolated from the specimens were examined for serotypes and minimum inhibitory concentration (MIC) using three types of antimycotic agents. Serotypes of Cryptococcus neoformans were all A and the MIC was 0.1-0.39 micrograms/ml for AMPH, 0.05-0.2 micrograms/ml for 5-FC and 0.2-0.78 micrograms/ml for miconazole (MCZ).

We examined the occurrence of low-grade Mycobacterium avium-intracellulare bacteremia and Cryptococcus neoformans fungemia in patients with the acquired immunodeficiency syndrome and the consistency of positive cultures obtained using a sensitive blood culture system (Isolator, E. I. Du Pont de Nemours, Wilmington, Del) for the recovery of these organisms. The blood culture records were reviewed, and the proportion of positive blood cultures yielding less than 1 colony-forming unit per milliliter of M avium-intracellulare or C neoformans was calculated. To determine consistency, a period of potentially detectable septicemia was defined as the period between 1 week before the first positive blood culture and the last positive blood culture, providing consecutive positive blood cultures were separated by less than 2 weeks. All positive and negative blood cultures obtained during the period of potentially detectable septicemia were considered in the data analysis. Overall, 40 (16.9%) of 236 cultures positive for M avium-intracellulare and 36 (57.1%) of 63 for C neoformans yielded less than 1 colony-forming unit per milliliter. Mycobacteremia was detected in 52 of 57 periods of potentially detectable septicemia in the first culture and in 56 of 57 in the first two (cumulative detection rates of 91.2% and 98.2%, respectively). Cryptococcemia was detected in 12 of 17 periods of potentially detectable septicemia in the first culture and in 15 of 17 in the first two (cumulative detection rates of 70.6% and 88.2%, respectively). Because of the sensitivity of the blood culture system and the consistency of M avium-intracellulare bacteremia and C neoformans fungemia in patients with the acquired immunodeficiency syndrome, it appears that two blood cultures are sufficient for the detection of most septic episodes caused by these organisms.

Fluconazole is a novel triazole antifungal agent developed by Pfizer Inc. and available in both oral and intravenous forms. It is characterized by a long serum half-life of 25 to 30 hours and good absorbability into tissues. In the present study, fluconazole was given to 12 patients with deep mycosis orally, intravenously or by local infusion. The patients included 4 cases of candidemia, 1 case each of candidemia and candiduria, candiduria, esophageal candidiasis, Candida hepatic abscess, pulmonary cryptococcosis and septicemia due to unspecified yeasts and 2 cases of pulmonary aspergillosis. Clinical efficacies of fluconazole against these infections were excellent in 2 cases, good in 8 and fair in 2. None of the patients reported any side effects. From the results of the study, fluconazole appears to be a useful and safe drug for the treatment of deep seated mycosis.

20 patients (18 men, 2 women), 10 of whom were HIV +, were given Fluconazole (F) for either systemic candidiasis (13 cases), histoplasmosis (1), or cryptococcosis (6). The localization of the Candida infections (12 C. albicans, 1 C. tropicalis), were: septicemic (2), urinary (7), bronchial (2), esophageal (5), uveal (1), soft tissue (2), and 1 undetermined localization but a positive serology (1). On day (d) 1, Candidiasis patients were given an initial dose of 400 mg (for septicemia) or 200 mg (other localizations) of FIV or PO, then 200 or 100 mg per d. The length of treatment lasted from 28 to 70 d. Evolution was favorable in all the patients. 4 relapses occurred after the end of treatment: at 10 d, a septicemic candidiasis (C. tropicalis) in 1 patient who had prosthetic endocarditis; and at 1 month, digestive candidiasis in 3 HIV + patients. For the patient, infected by Histoplasma capsulatum, despite a clinical improvement, urine were still positive at day 75. The patients with cryptococcosis (5 meningitidis in the AIDS patients) and renal (1) (kidney transplant) were given on the average 400 mg a d, IV or PO (mean length 8 weeks). Only 5 patients were evaluable. For 2 of the meningitis patients with other localizations, standard treatment was instituted due to the persistence of positive cultures. For the 2 other patients, the cerebrospinal fluid (1) and the urine (1) were sterilized by the 3d week. But they relapsed 1 month after the treatment stopped. For the 18 patients evaluable, clinical and biological tolerance was good except for 1 patient with transaminases rise for which fluconazole was probably the cause.

Capsule-deficient Cryptococcus neoformans (CN-CD) infection is very rare. The authors recently experienced the case of CN-CD infection with the complication of the syndrome of inappropriate antidiuretic hormone secretion (SIADH) in a 83 year old woman. She was admitted to our hospital with the complaints of fever and general fatigue on June 10, 1987. At the time of admission, there were no abnormal findings except a mildly lowered consciousness level on physical examination, there were no abnormal neurological finding nor meningeal signs. Laboratory data revealed a mild leukocytosis and hyponatremia. Chest X-P showed a few small nodular shadows scattered in both lungs. Antibiotics therapy was of no help and hyponatremia became worse. Then with the suspicion of SIADH, Demeclocycline was administered and limitation of water intake was decreased and hyponatremia improvement was used. Yeast-like fungi was detected in the venous blood culture and in the cerebrospinal fluid (cell count: 252/3) CN-CD by India-ink preparation and bacteriological nature were determined. We made a diagnosis of sepsis and meningitis by CN-CD accompanied with SIADH. In spite of Miconazole administration intravenously and intrathecally, she died 2 months after admission. The minimal inhibitory concentration (micrograms/ml) of antibiotics against the isolated CN-CD was as follows: Amphotericin B: 0.78, 5-PC: 1.56, Miconazole less than or equal to 0.05, Nystatin: 25, Ketoconazole: 0.78.

We report seven elderly patients with COPD who developed serious infectious complications during prolonged treatment with high doses of corticosteroids. Infections included invasive pulmonary aspergillosis, Herpes simplex stomatitis and esophagitis, cytomegalovirus pneumonia, bacterial sepsis, fungemia and meningitis due to Cryptococcus neoformans. Each of the three patients who developed invasive aspergillus pneumonia died. The efficacy of prolonged therapy with high doses of corticosteroids in patients with COPD is not proven. These cases illustrate the potential for serious infections in patients with COPD treated with corticosteroids.

Deep mycoses present new aspects characterized by deep, visceral mycotic localisations and septicemia, particularly in immunocompromised conditions. In immunodepressed patients (leukaemia, transplantation), the granulopenia descending to 500 elements/ml leads not only to invasive aspergillosis and candidosis but also to infections due to opportunistic fungi exceptionally or never seen formerly. AIDS favours opportunistic fungi related to defective cellular immunity as Cryptococcus neoformans, responsible of severe meningoencephalitis and septicemia, as Candida albicans responsible of thrush and oesophagitis, but also true pathogenic fungi (Histoplasma capsulatum) becoming opportunistic in such conditions. C. albicans provokes in heroin addicts a new septicemic syndrome with cutaneous, ocular and osteoarticular lesions and in leukaemic patients hepatic micro-abscesses soon after the neutropenic phase induced by chemotherapy. New methods for immunologic diagnosis (research of circulating fungal antigen), for clinical diagnosis (scanning, magnetic resonance). New strategy of antifungal chemotherapy (itraconazole, fluconazole) allow to a better knowledge and control of this new infectious pathology.

Thirty-one immunocompromised patients (22 renal allograft recipients, 5 patients receiving chronic corticosteroid therapy, and 4 patients undergoing chemotherapy for acute leukemia) with significant dermatologic infection, excluding typical cellulitis and herpesvirus infections, were retrospectively identified over a 12-year period. Of these 31 patients, 15 (48%) had infection restricted to their skin, 6 (19%) appeared to have primary cutaneous infection that spread hematogenously to other parts of the body, 2 (6%) had infections of adjoining nasal tissue that spread to contiguous skin, and 8 (26%) appeared to have disseminated systemic infection that spread to the skin. In six of the eight patients with apparent secondary skin involvement, the development of the cutaneous lesion was the first clinical indication of disseminated infection. Eleven immunocompromised patients (35%) with bacterial infection of the skin or subcutaneous tissue were identified. These patients could be divided into three categories: leukemic patients with bacteremic gram-negative infection metastasizing to the skin (3 cases), renal transplant recipients with recurrent staphylococcal infection on and around the elbow ("transplant elbow") or streptococcal sepsis from a site of cellulitis (5 cases), and immunocompromised patients with opportunistic bacterial infection due to Nocardia asteroides or atypical mycobacteria (3 cases). Seventeen immunocompromised patients (55%) with fungal infection of the skin or subcutaneous tissue were identified. These included 12 patients with opportunistic fungal infection (Cryptococcus neoformans, 4 cases; Aspergillus species, 3 cases; Paecilomyces, 2 cases; Rhizopus species, 2 cases; and Candida tropicalis, 1 case) and 5 patients with extensive, confluent cutaneous dermatophyte infections. One patient with protothecosis and two patients with extensive papillomavirus infection were identified. Of these latter two cases, one had his immunosuppression discontinued, with clearing of his extensive warts; the other had confluent warts of the face and neck that subsequently underwent malignant degeneration to squamous cell carcinoma while chronic immunosuppressive therapy was continued.(ABSTRACT TRUNCATED AT 400 WORDS)

Antibodies against the major capsular polysaccharide of Cryptococcus neoformans, glucuronoxylomannan (GXM), and a minor secreted polysaccharide, galactoxylomannan (GalXM), were surveyed by indirect enzyme immunoassay (EIA) in patients with cryptococcosis, with other mycoses, and in normal controls. Measurement of IgG levels against GalXM revealed cross reactions in candidiasis patients that were reduced by adsorption with Candida albicans cell walls. Measurement of IgM levels were subject to fewer cross reactions. The combination of adsorption with C albicans cell walls and measurement of IgM detected antibodies in 12 of 55 cryptococcosis patients. An end point equal to or greater than a titer of 1/16 excluded reactions in normals and limited cross reactivity in candidiasis patients to below 7%. This test has potential diagnostic significance in cryptococcosis patients who show no evidence of cryptococcal antigen circulating in the cerebrospinal fluid or serum. Reactions in this IgM assay were not spuriously due to rheumatoid factor. The major capsular GXM was much less serologically active and was subject to cross reactions with agents of bacterial sepsis. The specificity of the GalXM is directed mainly by the mannose and to a lesser extent by galactosyl residues.

Symptomatic cryptococcal pyelonephritis, meningitis, and disseminated cryptococcosis are described in a renal cadaver transplant recipient who subsequently died of Klebsiella pneumoniae sepsis. The presence of cryptococcuria and a subsequent positive CSF India ink stain led to the initial diagnosis of disseminated cryptococcosis. Therapy with 0.511 g of amphotericin B and 112.5 g of flucytosine for four weeks did not eradicate Cryptococcus from the kidney and was associated with hepatotoxicity. The importance of urinary examination and culture for C neoformans is emphasized. Cryptococcal pyelonephritis should be considered in the differential diagnosis of allograft rejection in the renal transplant patient.
