A 12-year-old, FIV-positive, domestic longhair cat was presented with a history of sneezing and coughing during the previous seven months. On thoracic radiographs, a prominent bronchial pattern and three focal, opacified nodules were seen. Cytology of bronchoalveolar lavage fluid demonstrated spherical, capsulate, narrow-necked, budding yeasts within macrophages. Culture of the fluid yielded a heavy growth of Cryptococcus neoformans var neoformans. The serum latex cryptococcal antigen agglutination test titre was 158. The cat was treated with itraconazole and the cough resolved over a 5-month period but then recurred. Repeat thoracic radiographs showed resolution of the pulmonary nodules but a persistent bronchial pattern. Adult nematodes and ova with morphology characteristic of Capillaria aerophila were seen in bronchoalveolar lavage fluid and no yeasts were cultured from the fluid. The cryptococcal titre was zero. The lungworm infection was treated successfully with abamectin and the cough resolved. Immunosuppression related to FIV infection may have predisposed this cat to sequential respiratory tract infections.

The characteristics of cardiac tamponade in patients with human immunodeficiency virus (HIV) disease were examined by evaluating the cases, case series, and related articles, including autopsy series, identified through a comprehensive literature search. One-hundred eighty-five cases of cardiac tamponade have been reported in patients with HIV disease. Sex data were available in 176 patients, of whom 154 (87%) were males. The mean age was 34.7 +/- 10.4 years (range, 11 months to 61 years). Mean CD4 cell count was 98 +/- 95 cells/mm3 (range, 3 to 430 cells/mm3). The most common etiology of pericardial tamponade was mycobacterial infection (78 patients), including Mycobacterium tuberculosis, Mycobacterium avium-intracellulare, and Mycobacterium kansasii. A bacterial cause was found in 20 patients (11%). Staphylococcus aureus was the predominant bacteria, followed by streptococci, Pseudomonas aeruginosa, Listeria monocytogenes, Klebsiella pneumoniae, and Rhodococcus equi. Lymphoma was found in 15 (8%) patients and Kaposi sarcoma in 13 (7%) patients. Numerous unusual organisms, including Cryptococcus neoformans, Nocardia asteroides, Aspergillus species, cytomegalovirus, and herpes simplex were also associated with cardiac tamponade in HIV patients. Occasionally, HIV itself was involved in the pathogenesis. In 48 patients (26%), no cause was found or reported. The most common clinical presentation was dyspnea, followed by fever, cough, chest pain, and cardiac arrest. The predominant pericardial fluid color composition was serosanguineous. The majority of patients died during hospitalization or in the immediate follow-up period. Vigilance for cardiac tamponade in patients with HIV disease, especially in those with opportunistic infections and/or malignancies, and cardiac symptoms, may result in early and proper management of cardiac tamponade in these patients.

Infections caused by Cryptococcus neoformans may range from an asymptomatic illness to lethal systemic disease, especially in immunocompromised hosts. Although cryptococcal infection most commonly involves the lungs or the central nervous system, it can disseminate to virtually any organ. Laryngeal cryptococcal infections are extremely rare--only 5 cases have been reported in the literature. Herein, we describe cryptococcal laryngitis occurring in a 55-year-old man with asthma and allergic fungal sinusitis. He presented with hoarseness and cough. He was treated with itraconazole followed by fluconazole therapy with complete recovery from his laryngeal infection. The patient was disease-free when last seen 10 months after the diagnosis. We present a summary of all reported cases of cryptococcal laryngitis.

Cryptococcus neoformans affections during HIV-infection are frequent and serious. The aim of this study was to analyse the epidemiological, clinical, biological and therapeutic characteristics of cryptococcal meningitis in HIV-positive patients, admitted into the Center for Tropical Diseases Ho Chi Minh City (Vietnam), during a 5-month period (May-September 2001). Twenty-one patients (20 men and one woman) were included (identification of C. neoformans from the cerebrospinal fluid). The mean age was 28 years. The majority of patients had been living in Ho Chi Minh City (48%). The use of drugs and unprotected sexual relations were the principal risk factors of HIV-infection. The paucity and the confusion of clinical signs and symptoms, along with a high frequency of meningitis have been analysed. Clinical presentation features included: headache (95%), emaciation (90%), oro-pharyngeal candidiasis (90%), stiff neck (80%), nausea/vomiting (70%), fever (67%), coughing (38%), diarrhoea (33%), skin lesions (5%), convulsion (5%), photophobia (5%), and hemiparesis (5%). The severity of the prognosis was mainly linked to the delay before hospitalization, to the possible association with other opportunistic infections, and to the availability of appropriate treatment.

Cryptococcus albidus, a non-neoformans species of the genus Cryptococcus, is generally regarded as a rare cause of disease. There have been only 14 previously reported cases in which this organism has been isolated as a pathogen, none of which occurred in a renal transplant recipient. A 23-year-old renal transplant recipient taking medication consisting of cyclosporine and prednisolone was admitted with a 10-day history of dry cough, fever and progressive dyspnea. The next day, his respiratory status deteriorated dramatically, and he developed acute respiratory distress syndrome (ARDS) and fulminant septic shock. On the eighth hospital day, tender macules on both his shins coalesced to form erythematous patches. Cryptococcus albidus was isolated by skin biopsy and tissue culture. We report here the first case of disseminated cryptococcosis caused by C. albidus in a renal transplant recipient who had been successfully treated with fluconazole monotherapy.

A 31-year-old male was admitted to Toranomon Hospital because of a cough and bilateral patchy infiltrates shown on the chest radiograph. He had been well prior to admission. Chest CT scan revealed patchy areas of air-space consolidation with air-bronchogram and adjacent ground-glass opacities, suggestive of bronchiolitis obliterans organizing pneumonia (BOOP). Transbronchial lung biopsy specimen confirmed the formation of epithelioid cell granulomas without necrosis and the coexistence of organizing pneumonia. The titer of serum cryptococcal antigen increased to 1:256. According to these findings, a diagnosis of primary pulmonary cryptococcosis was made, although cryptococci were neither recognized in the specimen nor cultured from the bronchial lavaged fluid. Chest radiograph showed spontaneous regression in a short period of time. However, itraconazole was administered for the prolonged cough, and the symptom disappeared. The titer of serum cryptococcal antigen decreased to 1:16 after the therapy. Pulmonary cryptococcosis should be considered as one of the differential diagnoses when chest CT scan shows combined air-space consolidation and ground-glass opacities.

Noninfectious or unusual infectious diseases may present with clinical, radiological and laboratorial characteristics of community-acquired pneumonia (CAP). Usually their presence is only suspected after treatment failure, leading to inappropriate interventions, unnecessary costs and risks related to the untreated potentially life-threatening disease. The present study aimed to assess the noninfectious or unusual infectious diseases that may be misdiagnosed as CAP that progresses with treatment failure. Sixteen hospitalized patients with presumptive diagnosis of CAP and treatment failure were described. The most prevalent symptoms were fever and cough. Radiological pattern of air-space disease was observed in 10 (62%) patients. The diagnosis was established by autopsy (12%) or invasive procedures (88%), as follows: open lung biopsy (nine), flexible fiberoptic bronchoscopy (two), transthoracic fine needle aspiration (two) and bone marrow aspiration (one). Eight patients had noninfectious diseases: pulmonary embolism, cryptogenic organizing pneumonia, Wegener's granulomatosis, hypersensitivity pneumonitis, bronchocentric granulomatosis, neoplastic disease and acute leukemia. The unusual infectious diseases were: tuberculosis, cryptococcosis, actinomycosis, histoplasmosis and paracoccidioidomycosis. Patients with noninfectious or unusual infectious diseases may present with symptoms and radiological findings that mimic CAP. These diseases should always be suspected in patients who do not respond to initial empirical antimicrobial treatment, especially young patients or those without comorbidity.

Disseminated cryptococcosis is a rare and often fatal disease in children. The majority of cases usually occur in individuals with defective cell-mediated immunity, most commonly due to HIV infection. The authors here in report an 8-year-old girl from Nepal who presented with fever, cough, headache, lymphadenopathy, hepatosplenomegaly and cutaneous lesions. Lymph node biopsy revealed multiple granulomas composed of histiocytes and epitheliold cells along with numerous yeast forms of cryptococcus. Cultures of CSF, sputum and urine yielded cryptococcus neoformans. Surprisingly,the immune function in terms of T-cell number, CD4 : CD8 ratio, serum immunoglobulins and HIV serology was normal. After the diagnosis of disseminated cryptococcosis was established, the patient was treated with 5-fluorocytosine (100 mg/kg/day) for initial two weeks and amphotericin B (1 mg/kg/day) for 13 weeks. Patient responded well to the treatment with disappearance of presenting symptoms, cutaneous lesions, and lymphadenopathy, though she still had hepatosplenomegaly, which also decreased. Unfortunately, she developed loss of vision in 10th week of therapy. The patient was discharged on oral fluconazole (6 mg/kg/day) and no recurrence was found during the follow-up period of more than 9 months. This is the first case of disseminated cryptococcosis with no detectable immune deficit, from India.

A 41-y-old male had been diagnosed as having community acquired pneumonia (CAP) with consolidations in the chest radiograph, fever and cough. Since clarithromycin and ss-lactam agents were not effective, bronchoscopic examination was performed. Indian ink staining of bronchial wash smears revealed yeast-like cells with a thick capsule, and Cryptococcus neoformans was isolated several d later. Serum glucuronoxylomannan antigen was > or = x 1024. The patient was treated with itraconazole for 16 weeks.

A 29-year-old HIV seropositive male patient from Manipur presented with fever, cough, weight loss and asymptomatic papules and nodules all over the body. Differential diagnoses of secondary syphilis, histoplasmosis, cryptococcosis and penicilliosis were considered. Histopathological and mycological study of the skin biopsy tissue, and blood culture confirmed the diagnosis of penicilliosis. Although penicilliosis, an AIDS-defining illness, is restricted to Southeast Asia, more and more cases are being recognized in non-endemic countries.
