The importance of serological assays in diagnosing acute pulmonary histoplasmosis
Provedor de dados: 80
Autores: Freitas,RS; Carvalho-Vivi,JO; Zamboni,IM; Assis,CM; Costa-Martins,JE; Vicentini-Moreira,AP.
Histoplasmosis is a systemic mycosis caused by inhalation of Histoplasma capsulatum microconidia. The disease does not normally affect immunocompetent individuals after a single, transient inhalation exposure. However, longer exposure may cause chronic or disseminated acute pulmonary infection. Herein, we report the case of a 24-year-old immunocompetent patient, who presented fever, cough and dyspnea for one month. The chest radiography revealed interstitial infiltrate and diffuse micronodules. The patient reported having had close and prolonged contact with bats. Diagnosis was confirmed by positive double immunodifusion and immunoblotting assays. She was treated with ketoconazole (400 mg) and there was complete resolution of the disease.

Comparación de las coloraciones de Giemsa y Grocott en el diagnóstico de la histoplasmosis
Provedor de dados: 38
Autores: Bava,Amadeo Javier; Zuiani,María Fernanda.
El diagnóstico de histoplasmosis se realiza tradicionalmente mediante el reconocimiento de típicas levaduras intracelulares de Histoplasma capsulatum en preparaciones microscópicas teñidas con Giemsa. Se comparó la eficacia de una modificación rápida de la técnica de Grocott (MRG) y la tradicional de Giemsa para el diagnóstico de la histoplasmosis, a partir de la aplicación de ambas a 10 secreciones respiratorias, 8 escarificaciones de lesiones cutáneas y una biopsia ganglionar, pertenecientes todas a pacientes con sospecha clínica de esta micosis. En 15 de las 19 muestras no se encontraron diferencias significativas en la capacidad y rapidez para arribar al diagnóstico, mientras que en las 4 restantes, fueron reconocidas con la MRG estructuras que pasaron...

Laboratorio clínico y micológico en pacientes con histoplasmosis y síndrome de inmunodeficiencia adquirida
Provedor de dados: 38
Autores: Trombetta,Luis; Bava,Amadeo Javier.
Se evaluaron retrospectivamente los resultados del laboratorio general y micológico de 15 pacientes varones con histoplasmosis asociada al SIDA internados en la Sala 11 del Hospital Muñiz de Buenos Aires, desde el 1/1/98 al 31/12/03. Los pacientes desarrollaron la forma diseminada aguda de la histoplasmosis; trece de ellos fueron dados de alta y los dos restantes fallecieron a pesar de la administración del tratamiento antifúngico específico. Las alteraciones sobresalientes reveladas por los estudios de laboratorio fueron la presencia de anemia, leucopenia, aceleración de la velocidad de eritrosedimentación y elevación de las aminotransferasas hepáticas (TGO y TGP) y de la fosfatasa alcalina. Sin embargo, a pesar del compromiso hepático, la bilirrubinemia...

Histoplasmosis diagnosed after arthroscopy of the knee: case report
Provedor de dados: 55
Autores: Falster,Lorenzo; Marin,Maurício B.; Gomes,João Luiz Ellera.
ABSTRACTFungal arthritis is a rare complication of arthroscopic surgeries, but its possibility should always be considered due its deleterious effects on any joint. Infection caused by the fungus Histoplasma capsulatum is the most common cause of respiratory tract infections by fungi, meanwhile histoplasmosis arthritis is more rare than all other fungal infections. However, their atypical forms of arthritis and the importance of early diagnosis and treatment cannot be over-emphasized. Herein we report a case of knee monoarthritis in an immunocompetent patient with histoplasmosis arthritis following an arthroscopic meniscetomy, diagnosed by synovial biopsy and culture performed during a second arthroscopic procedure. The joint was debrided in this second...

Bilateral afrenal nodules due to histoplasmosis in an elderly
Provedor de dados: 55
Autores: Carvalho,Flávio Pedreira de Freitas de; Curiati,José Antônio Esper; Mauad,Thaís; Incerti,Milena Mendes; Jacob Filho,Wilson.
We report a case history of an 84-year-old elderly male patient that presented with a clinical picture suggestive of adrenal failure and bilateral adrenal nodules detected by abdominal computed tomography. A fine needle-guided biopsy was inconclusive for achieving a final diagnosis. The patient died due to septic shock and the autopsy disclosed histoplasmosis with extensive bilateral necrosis of the adrenal glands. Although the adrenal involvement in chronic disseminated histoplasmosis has been described, there have been few reports of the infection being associated with adrenal insufficiency.

Posaconazole as rescue therapy in African histoplasmosis
Provedor de dados: 55
Autores: Gonçalves,Daniel; Ferraz,Catarina; Vaz,Luisa.
Posaconazole Histoplasmosis Salvage therapy African histoplasmosis is a granulomatous mycosis caused by Histoplasma capsulatum var. duboisii. Treatment is usually extrapolated from guidelines for classical histoplasmosis, and includes 2-4 weeks of amphotericin B followed by a step-down maintenance therapy with itraconazole. Pediatric usage of posaconazole, an oral second-generation azole, remains off-label, but recent surveys show that it is safe and well tolerated in children. We report a case of disseminated African histoplasmosis in a 12-year-old boy from Guinea-Bissau. Therapy with amphotericin B and itraconazole led to a progressive clinical deterioration. A dramatic and lasting improvement was observed using posaconazole. He completed 12 months of...

Disseminated histoplasmosis in HIV positive patients in Espírito Santo state, Brazil: a clinical-laboratory study of 12 cases (1999-2001)
Provedor de dados: 55
Autores: Casotti,Janaina Aparecida Schineider; Motta,Tânia Queiroz Reuter; Ferreira Júnior,Carlos Urbano Gonçalves; Cerutti Junior,Crispim.
Twelve cases of histoplasmosis in HIV-infected patients were found in a retrospective analysis at the Hospital Universitário Cassiano Antônio de Moraes of the Universidade Federal do Espírito Santo (HUCAM), Vitória (ES), from June 1999 to May 2001. The frequency of histoplasmosis among HIV-positive patients was 2.1% in the infectious diseases division of the hospital during this period. Histoplasmosis compromised mainly males (11/12), 27 to 44 years old, and residents of the metropolitan urban area (10/12). Alcohol abuse and tobacco smoking were described in 10 of the 12 patients. For all patients, this was the first opportunistic infection. Two of the 12 patients died; 10 patients had disseminated disease, one patient had an intestinal presentation and...

Provedor de dados: 58
Autores: Passos,Angela Noronha; Kohara,Valdelene Sayuri; Freitas,Roseli Santos de; Vicentini,Adriana Pardini.
Several reports showed outbreaks of histoplasmosis acquired while bat-inhabited caves were visited by tourists, miners or researchers. We evaluated the performance of double immunodifusion (DI) and immunoblotting (IB) assays, employed for the histoplasmosis outbreak elucidation occurred in Vale do Paraíba, São Paulo. The existence of epidemiologic link, four patients with clinical signs suggestive of histoplasmosis and mycological confirmation has made that all 35 individuals involved to the cave visit were subjected to serological evaluation. By DI, we observed reactivity against H. capsulatum antigen in a single serum examined nearly 20 days after exposure to fungal propagules. On the other hand, IB showed reactivity against H and M fractions in 50% of...
