Cryptococcosis in seven horses.

The clinical, radiographic and post-mortem findings in 6 horses with cryptococcal pneumonia and one horse with an abdominal cryptococcal granuloma are described. In pulmonary cryptococcosis, the lesions were either diffuse and multiple, with bilateral lung involvement, or localised mainly to the dorsocaudal region of one lung. The cases of diffuse multiple cryptococcosis were thought to be associated with haematogenous spread of the fungus after gastrointestinal infection and dissemination from regional lymph nodes. The localised form of the disease was thought to have been associated with inhalation of cryptococci. In all cases of pulmonary cryptococcosis, encapsulated yeast-like organisms were demonstrated in Wright's-stained sediment of tracheal washes. In the horse with the abdominal granuloma, cryptococci were present in a fine needle aspirate sample. Isolates of Cryptococcus neoformans var gattii were recovered from 2 of the 5 horses in which cultures were attempted. In addition to a history of previous illness that may have predisposed to infection, most horses in this report had been in areas in which Eucalyptus camaldulensis, or the closely related E rudis, were growing. In humans, an epidemiological relationship between E camaldulensis and infection with C neoformans var gattii has been suggested. Cases of equine cryptococcosis carry a poor prognosis and treatment was not attempted in any of these cases.

[A case of primary pulmonary cryptococcosis showing lobar pneumonia on chest X-ray].

A 36-year-old male who had been in good health visited our hospital because of fever, productive cough and lobar pneumonia of the right lower lobe. Bronchoscopic examination revealed pulmonary cryptococcosis. After the initiation of fluconazole the pneumonia started to improve, however, it was aggravated after the discontinuation of fluconazole because of liver dysfunction induced by it. The pulmonary cryptococcosis improved by lobectomy of the right lower lobe. There have been few reports of lobar pneumonia caused by primary pulmonary cryptococcosis. We report this case with fourteen other cases of primary pulmonary cryptococcosis which have been experienced in our hospital.

Improvement of amphotericin B activity during experimental cryptococcosis by incorporation into specific immunoliposomes.

Cryptococcosis is an opportunistic infection that is responsible for increased morbidity and mortality in patients with the acquired immunodeficiency syndrome. The high toxicity of the antifungal agent that is mainly used against cryptococcosis, amphotericin B (AMB), accounts for the need for new treatments, especially in patients with the acquired immunodeficiency syndrome because of the high relapse rate of cryptococcosis. Drug targeting may be one of these alternate treatments. Since we have demonstrated that an immunoglobulin G1 (IgG1) anti-Cryptococcus neoformans serotype A monoclonal antibody (E1) was protective during experimental cryptococcosis in mice, we investigated whether specific targeting of AMB with liposomes that bear E1 would improve the therapeutic index of the drug. For that purpose, in vitro and in vivo experiments were designed to compare the specificities and activities of these liposomes with those of control immunoliposomes bearing a nonrelated IgG1 monoclonal antibody (CY34). The immunoliposomes were prepared by covalently linking E1 or CY34 and small unilamellar vesicles. When immunoliposomes were incubated with yeast cells, only E1-bearing liposomes recognized C. neoformans. In vivo, mice that were treated 24 h after infection with one injection of AMB (0.12 mg/kg of body weight) intercalated into E1-bearing liposomes survived significantly longer than did those given the same dose of AMB alone or AMB intercalated into nontargeted liposomes or control immunoliposomes. None of the mice that were given control treatments did statistically better than those that were given AMB. Keeping in mind that this kind of therapy requires knowledge of the antigenic type of the infecting organism, the results suggest that specific targeting of small doses of AMB improve the efficacy of AMB and might be an alternative to the use of larger doses of AMB.

Efficacy of ER-30346, a novel oral triazole antifungal agent, in experimental models of aspergillosis, candidiasis, and cryptococcosis.

ER-30346 is a novel oral triazole with a broad spectrum of potent activity against a wide range of fungi. In the present study, we investigated the therapeutic effects of oral ER-30346 on experimental local infections caused by Aspergillus fumigatus, Candida albicans, and Cryptococcus neoformans and compared them with those of itraconazole and fluconazole. In experimental murine models of pulmonary aspergillosis, candidiasis, and cryptococcosis, ER-30346 reduced the numbers of CFU in the lungs significantly compared with the numbers of CFU in the lungs of the controls (P < 0.05). ER-30346 was as effective as or more effective than itraconazole against pulmonary aspergillosis. Against pulmonary candidiasis and cryptococcosis, ER-30346 was more effective than itraconazole and was as effective as fluconazole. ER-30346 was also effective against pulmonary candidiasis caused by fluconazole-resistant C. albicans. In mice with intracranial cryptococcosis, ER-30346 reduced the numbers of CFU in the brains significantly compared with the numbers of CFU in the brains of the controls (P < 0.05) and was more effective than itraconazole and as effective as fluconazole. In an experimental model of oral candidiasis in rats, ER-30346 reduced the numbers of CFU in oral swabs significantly compared with the numbers of CFU in oral swabs from the controls (P < 0.05) and was more effective than itraconazole and as effective as fluconazole. Thus, ER-30346 shows efficacy in murine aspergillosis, candidiasis, and cryptococcosis models. Further studies are needed to determine the potential of ER-30346 for use in the treatment of these infections.

Cryptococcosis in the era of AIDS--100 years after the discovery of Cryptococcus neoformans.

Although Cryptococcus neoformans and cryptococcosis have existed for several millennia, a century has passed since the discovery of this encapsulated yeast and its devastating disease. With the advent of the AIDS pandemic, cryptococcal meningitis has emerged as a leading cause of infectious morbidity and mortality and a frequently life-threatening opportunistic mycosis among patients with AIDS. Both basic and clinical research have accelerated in the 1990s, and this review attempts to highlight some of these advances. The discussion covers recent findings, current concepts, controversies, and unresolved issues related to the ecology and genetics of C. neoformans; the surface structure of the yeast; and the mechanisms of host defense. Regarding cell-mediated immunity, CD4+ T cells are crucial for successful resistance, but CD8+ T cells may also participate significantly in the cytokine-mediated activation of anticryptococcal effector cells. In addition to cell-mediated immunity, monoclonal antibodies to the major capsular polysaccharide, the glucuronoxylomannan, offer some protection in murine models of cryptococcosis. Clinical concepts are presented that relate to the distinctive features of cryptococcosis in patients with AIDS and the diagnosis, treatment, and prevention of cryptococcosis in AIDS patients.

Pulmonary cryptococcosis: CT findings in immunocompetent patients.

PURPOSE: To evaluate retrospectively the computed tomographic (CT) findings in immunocompetent patients with pulmonary cryptococcosis. MATERIALS AND METHODS: Institutional review board approval was obtained with a waiver of informed consent, and the study complied with requirements of the Health Insurance Portability and Accountability Act. Chest CT scans of 10 immunocompetent patients with clinically proved pulmonary cryptococcosis were retrospectively reviewed by four reviewers in consensus. Criterion for diagnosis of pulmonary cryptococcosis was (a) the histopathologic presence of the organism at lung biopsy or (b) a positive culture of a respiratory specimen or positive serum cryptococcal antigen test with clinical or radiographic evidence of active pulmonary infection. Patients included six women and four men ranging in age from 46 to 73 years (mean, 59 years). Scans were evaluated for nodules, masses, areas of ground-glass attenuation or of hazy increased attenuation, areas of consolidation, areas of cavitation, pleural effusions, linear opacities, septal thickening, lymphadenopathy, extent of parenchymal involvement, and distribution. RESULTS: The most common CT finding was pulmonary nodules (n = 9). Multiple nodules (n = 7) were more common than solitary nodules (n = 2). Nodules most commonly occupied less than 10% of the pulmonary parenchyma (n = 7), measured less than 10 mm in diameter (n = 7), and had middle and upper lung predominance (n = 6). The majority of the nodules were well defined with smooth margins (n = 7). Multiple nodules were usually bilaterally distributed (n = 5). Masses (n = 2), lymphadenopathy (n = 2), areas of consolidation (n = 2), areas of hazy increased attenuation (n = 1), pleural effusion (n = 1), and areas of cavitation (n = 1) were uncommon. CONCLUSION: CT most commonly demonstrated pulmonary nodules in immunocompetent patients with pulmonary cryptococcosis. The nodules were most often multiple, small, well defined, and smoothly marginated with middle and upper lung predominance.

Role of fluconazole in the management of AIDS-related cryptococcosis, according to daily dosing.

No unanimous consent has been reached about treatment guidelines of cryptococcosis in the setting of AIDS, as well as about optimal fluconazole dosing in both initial and suppressive therapy. In order to evaluate the relationship between fluconazole dosing and clinical and microbiological outcome of AIDS-related cryptococcosis, a retrospective study was carried out on 30 consecutive patients. Among the 12 subjects treated with fluconazole doses < 400 mg/day, an unfavorable course was significantly more frequent (early mortality, poor clinical and microbiological response, appearance of early relapses) compared with the 18 patients who received daily doses > or = 400 mg, while no differences were observed between the two treatment groups according to known risk factors for a poor prognosis. When assessing maintenance treatment (22 evaluable cases), the 15 patients receiving oral fluconazole at doses < 200 mg/day showed earlier disease relapse and mortality as opposed to the 7 individuals treated with high-dose fluconazole (> or = 200 mg/day), in the absence of significantly different risk factors for disease recurrence. Our experience pointed out a significant difference in clinical activity of fluconazole in AIDS-related cryptococcosis according to its daily dosing, and suggested 400 and 200 mg as the threshold daily dose for an effective initial and suppressive therapy, respectively, since the probability of treatment failure seemed greater with low-dose drug administration, after controlling data for prognostic markers of disease severity. Controlled studies are warranted, comparing high-dose fluconazole with standard regimens containing amphotericin B in the treatment of AIDS-associated cryptococcosis, and identifying the best fluconazole dosing for both acute-phase and maintenance treatment.

The evolution of pulmonary cryptococcosis: clinical implications from a study of 41 patients with and without compromising host factors.

Over 14 years 41 patients were diagnosed as having pulmonary cryptococcosis. Cryptococcus neoformans remained localized to the lung in 12 cases and disseminated in the remaining 29. Thirty-four patients were compromised hosts. Disseminated disease developed in 28 of these 34, and four of these 28 patients with disseminated disease presented with concomitant pulmonary and meningeal infections. In all the remaining 24 central nervous system involvement developed 2 to 20 weeks after the finding of an abnormal chest roentgenogram. Seven patients were normal hosts, and in six of these cases disease remained localized to the lung. Four important conclusions were drawn from this study: pulmonary cryptococcosis is rarely considered in the differential diagnosis of an abnormal chest roentgenogram, thereby leading to missed diagnoses and therapeutic errors; the natural history of untreated pulmonary cryptococcosis in compromised hosts is extrapulmonic dissemination; compromised hosts with pulmonary cryptococcosis should receive antifungal therapy because of a high propensity for dissemination; and normal hosts in whom dissemination has been excluded generally do not need antifungal therapy.

Cryptococcus neoformans isolated from human dwellings in Rio de Janeiro, Brazil: an analysis of the domestic environment of AIDS patients with and without cryptococcosis.

One hundred and fifty-four human dwellings in the metropolitan area of Rio de Janeiro, Brazil were studied. A total of 824 samples of indoor dust, outdoor soil and avian droppings were collected. Cryptococcus neoformans var. neoformans was isolated from 20 (13%) dwellings, comprising five (15.6%) of 32 dwellings of patients with AIDS-associated cryptococcosis; four (8.9%) of 45 dwellings of patients with AIDS but without cryptococcosis; and 11 (14.3%) of 77 dwellings of apparently healthy individuals (P>0.05). The principal factor associated with domiciliar contamination by C. neoformans var. neoformans was the presence of avians in the domestic environment or nearby the home. Cryptococcosis was more frequent among AIDS patients residing in dwellings from which C. neoformans var. neoformans was isolated than among AIDS patients from whose domestic environment the fungus was not demonstrated by the methods used (odds ratio (OR)=2.05). These findings suggest that the distribution of C. neoformans var. neoformans in Rio de Janeiro is not restricted to the classically known biotopes as well as reinforce the possibility of exogenous infection in opportunistic cryptococcosis, including exogenous infection acquired in the domestic environment.

Cutaneous manifestations of disseminated cryptococcosis.

Five patients with disseminated cryptococcosis had lesions on the extremities resembling cellulitis, which evolved into areas of blistering and ulceration in three patients. All had underlying disease and were medically immunosuppressed. Disseminated cryptococcosis appears to present with cellulitis or herpes-like vesiculation more commonly than is currently appreciated. India ink preparations of aspirates from areas of cellulitis or Tzanck preparations from blisters may show characteristic organisms, and make possible an immediate diagnosis of cutaneous cryptococcosis. If cutaneous infection is confirmed by performing biopsies and growing cultures, dissemination must be presumed and the patient treated with a full course of systemic antifungal therapy. With increasing awareness of cutaneous involvement, some cases of disseminated cryptococcosis will be diagnosed sooner, leading to earlier therapy and improved prognosis.

[Cryptococcosis of the central nervous system. A report of five cases].

INTRODUCTION: Since the 1980s, in relation to the spread of AIDS, there has been an enormous increase in cryptococcosis, a mycotic disorder which usually affects the central nervous system (CNS). This disease is caused by Cryptococcus neoformans, a microorganism acquired by inhalation of bird excrement. This germ produces a capsule which protects it from phagocytosis, can synthesize melanin which acts as an antioxidant of the cytotoxic lymphocytes and can reproduce at body temperature. Clinically it may show as chronic or subacute meningitis and/or encephalitis, as endocranial hypertension or as an intracranial space occupying lesion (crytococcoma). To establish the diagnosis, Chinese ink, culture and the latex agglutination test are useful. Treatment is with amphotericin B associated or not with fluocytokine and fluconazole, the protocol used depending on the clinical form. OBJECTIVE: To review the most up-to-date literature on cryptococcosis of the CNS to study the condition in relation to five cases. CLINICAL CASES: We report five patients with cryptococcosis of the CNS diagnosed and treated in the Instituto Nacional de Neurología y Neurocirugia de la Habana, Cuba, showing an increase in the frequency of the occurrence of cases not related to HIV infection, great variety of clinico-humoral presentation and the characteristics of the treatment given. CONCLUSION: Cryptococcosis can be cured completely when the condition is diagnosed early; without treatment it is invariably fatal.

Cryptococcosis and sarcoidosis: strange bed-fellows. A report of five cases.

BACKGROUND AND AIM: Sarcoidosis is known to predispose to cryptococcal infection. In this case series, variations in presentation, diagnostic dilemmas and responses to treatment are highlighted. METHODS: Of several hundred patients referred to the sarcoidosis clinic at The Prince Charles Hospital, Brisbane and to the private clinic of the co-author between 1990 and 2002, five subsequently developed cryptococcal infections as a complication of sarcoidosis. All five subjects were treated by the co-author (RKAA). A review of the literature was also performed. RESULTS: Cryptococcal infection occurred in 4 patients with sarcoidosis being treated with steroids and one patient who was not on treatment. All responded to antifungal therapy. Cryptococcosis was diagnosed by transbronchial (2), bronchial (1) and cutaneous (2) biopsies. Fluconazole was used in those with pulmonary infections but not in cutaneous disease where excision sufficed. One patient with pulmonary cryptococcosis from immunosuppressants also developed a nocardial brain abscess. CONCLUSIONS: Our series of patients with sarcoidosis and cryptococcal infections is unique in Australia. Although an unusual infection, cryptococcosis should always be considered in patients with sarcoidosis as it may be overlooked particularly in the lungs and can be fatal if untreated. Further immune dysregulation through steroid use may contribute significantly to the disease manifestations. Understanding why cryptococcosis and not other infections is more common in patients with sarcoidosis may reveal more about the mechanisms of granuloma formation and the nature of sarcoidosis itself.

[Cryptococcosis: presentation of 26 cases].

BACKGROUND: Cryptococcosis is more frequently observed since the appearance of the acquired immunodeficiency syndrome (AIDS). AIDS has modified the clinical and evolutive forms of the disease. This study reviews the changes produced in the infection from the context of AIDS. METHODS: The present is a retrospective study (1985-1990) including patients presenting: 1) a positive latex agglutination test (serum or spinal fluid) or 2) a Sabouraud culture positive for cryptococcus. Clinical histories were revised collecting clinical, radiologic, analytic, therapeutic and evolutive data. RESULTS: Twenty-six patients (21 males) were included in the study. Twenty patients had the human immunodeficiency virus. The clinical picture was: 22 cases with cryptococcal meningitis (13 with hematogenous participation), 3 with pulmonary cryptococcosis and one with disseminated cryptococcosis without meningeal involvement. The patients with AIDS had: greater frequency of positive hemocultures, higher serologic titers and fewer with the meningeal syndrome. The number of T4 lymphocytes was lower than 150 elements/ml in AIDS patients. In 17 patients treatment with amphotericin B and 5-fluorocytosine was administered, 5 received amphotericin B and two fluconazole and two did not receive the above since they had not been diagnosed alive. There were 6 deaths and 10 relapses in 6 AIDS patients and none in the remaining patients. CONCLUSIONS: The incidence of cryptococcosis has increased as a consequence of AIDS. In these patients the disease occurs in advanced stages of immunodeficiency and frequently in disseminated, severe and paucisymptomatic forms. Treatment is usually effective although a maintenance therapy is required to avoid relapse.

Radiographic manifestations of pulmonary cryptococcosis.

Pulmonary cryptococcosis may occur in both immunocompromised and immunocompetent hosts. The purpose of the present study was to review the radiologic findings of pulmonary cryptococcosis in King Chulalongkorn Memorial Hospital. The radiographs and computed tomography of the chests of the patients who had a diagnosis of pulmonary cryptococcosis, between 1998-2001, were retrospectively reviewed. Seven patients were included. Five were HIV infected, three had diffuse reticulonodular opacities, two (of the three) patients also had accompanying cavities; two had solely pleural effusion. Two patients were immunocompetent; one had a pulmonary nodule and another one had an endobronchial lesion and multiple pulmonary masses in the collapsed lung seen on CT scan, which were consistent with cryptococcoma. None had adenopathy. There was a difference in the radiologic manifestations between immunocompromised and immunocompetent hosts. Knowledge in radiographic features in pulmonary cryptococcosis should help radiologists to early recognize the disease and may improve the treatment outcome.

[Surgical treatment of pulmonary cryptococcosis].

OBJECTIVE: To summarize the clinical features, diagnosis and surgical experience of pulmonary cryptococcosis. METHODS: Twenty-seven patients with pulmonary cryptococcosis were treated surgically. There were 22 males and 5 females. The mean age at operation was (47.5 +/- 7.9) years. Open thoracotomy was performed for 17 patients, thoracoscopic surgery or video-assisted mini-thoracotomy surgery was performed for 10 patients; lobectomy was performed for 16 patients, pulmonary wedge resection was done for 9 patients; thoracoscopic pulmonary biopsy was conducted in 2 patients. RESULTS: Complete removal of lesion was obtained in 25 patients and pulmonary biopsy was obtained in 2 patients. The 26 patients were followed up for 2 to 5 years, and 25 of them were cured. There was no post-operative deaths and no complications in the 25 patients. The complication of meningitis and recurrence were found in only one case. CONCLUSIONS: Pulmonary cryptococcosis shows no specific clinical features and X-ray manifestations. For localized pulmonary cryptococcosis, surgical resection may be an effective procedure for its diagnosis and treatment. Because of its minimal invasiveness and short length of hospital stay, thoracoscopic surgery may be superior to open thoracotomy.

[Pulmonary cryptococcosis occurring 6 months after cladribine therapy for relapsed follicular lymphoma].

We report a case of follicular lymphoma in which pulmonary cryptococcosis occurred with cladribine therapy. The case involved a 72-year-old man. He was diagnosed as having follicular lymphoma, grade 1, clinical stage IVA from a tongue tumor biopsy in January 2003. A total of 6 courses of R-CHOP therapy was performed, but no clear effect was found. A new cervical lesion appeared, so he was treated with a total of 2 courses of R-EPOCH therapy, and the effect was classed as stable disease. We started cladribine therapy (0.09 mg/kg, seven days of continuous infusion) from February 2004, and complete remission was achieved after 4 courses of cladribine therapy. In January 2005, an abnormal nodular shadow in the right S10 area was found on chest CT images which was diagnosed as pulmonary cryptococcosis by serum antigen and a trans-bronchial lung biopsy. We started fluconazole (200 mg a day, initially intravenous drip infusion, followed by oral intake), following which both the pulmonary shadow and serum antigen improved. Afterward, the fifth course of cladribine therapy and local radiation therapy were performed against a relapse of lymphoma, but cryptococcosis did not reappear. The prolonged bone marrow suppression after cladribine therapy was considered to be a severe adverse event. These findings suggest that it is very important to pay attention to any opportunistic infection such as pulmonary cryptococcosis.

[A report of 12 cases of primary pulmonary cryptococcosis].

OBJECTIVE: The purpose of this study was to analyze the chest CT findings of immunocompetent patients with primary pulmonary cryptococcosis and to evaluate the utility of CT-guided percutaneous biopsy in the diagnosis. METHODS: Chest CT scans of 12 immunocompetent patients with biopsy-proven primary pulmonary cryptococcosis were analyzed for the number of lesions, morphologic characteristics, distribution of parenchymal abnormalities, and the presence of lymphadenopathy and pleural effusion. Lung specimens were obtained by CT guided percutaneous biopsy (n = 9) and/or surgical resection (n = 7). A pulmonary pathologist reviewed the specimens. RESULTS: The main manifestations were classified into two patterns. Localized multiple mixed lesions (nodules and/or masses and/or consolidation) were found in 67% (8/12) of the cases, and single nodules were found in 33% (4/12). Associated findings included air bronchograms (n = 9), cavity (n = 2), and CT halo sign (n = 4). Lung specimens were obtained by CT guided percutaneous biopsy in 9 cases, of which 7 (78%) were confirmed by pathology. Seven cases recovered after treatment with fluconazole, but cryptococcal meningitis occurred in 1 case 5 month after single excision. CONCLUSIONS: Chest CT findings of primary pulmonary cryptococcosis in immunocompetent patients have a predominant pattern of localized multiple mixed lesions. CT guided percutaneous biopsy is helpful in confirming the diagnosis. Fluconazole is effective in the treatment of pulmonary cryptococcosis in these patients.

[Cryptococcosis of the central nervous system. Clinical and diagnostic characteristics].

BACKGROUND: Evaluation of the clinical features and diagnostic methods in the cryptococcosis of central nervous system (CNS), so as to facilitate a rapid recognition which may result in earlier diagnosis in view of the rapid increase in frequency shown in that condition. METHODS: A retrospective study of 13 patients with CNS cryptococcosis seen during the last 4 years. The isolation of C. neoformans in CSF, cerebral biopsy or other appropriate tissue was required for inclusion. The following were evaluated: 1) Age, sex, and underlying disease; 2) Clinical features; 3) Yield of biochemical, microbiological, pathological and imaging diagnostic procedures; 4) Treatment and evolution. RESULTS: Age (X +/- SD): 37 +/- 20 years (range: 15-81). Sex: 77% males. Underlying disease was identified in 10 cases (77%): HIV infection in 7 (54%), diabetes mellitus in 2, alcohol abuse in 2, systemic erythematous lupus on corticoid and immunosuppressant therapy in 1 and chronic liver disease in 1. Clinical features on admission: abnormal behaviour in 10 (77%), headache in 10, low/high grade fever in 9 (69%), abnormal consciousness in 7, respiratory features in 5 (38%); motor deficit, cranial nerve involvement and visual abnormalities in 4 (31%) each; and meningeal signs in 3. Investigation of CSF was carried out in 12 cases. The biochemical studies were normal in 5 (42%). China ink stain was positive in 55% of cases, and latex agglutination in 80%. CSF culture was diagnostic in 92% of cases and the culture for C. neoformans was positive in 2 cerebral and one pulmonary biopsies and in two urine cultures. All patients were treated with amphotericin B and flucytosine was associated in 9. Two patients were subsequently treated with fluconazole. The outcome was good in 8 patients, and 4 had sequelae. One case relapsed. CONCLUSIONS: 1) HIV infection is the most common underlying disease. 2) There is a high rate of CNS cryptococcosis with normal CSF or with mild biochemical abnormalities. 3) The yield of the microbiological studies of CSF is high, with diagnostic confirmation in 92% of cases. 4) Differences in CNS cryptococcosis were not found between cases with HIV infection and those with other underlying diseases.
