Adiaspiromicose pulmonar tratada sem antifúngicos / Pulmonary adiaspiromycosis treated without antifungal drugs

Relata-se caso de lavrador de 40 anos acometido por adiaspiromicose pulmonar, com diagnóstico etiológico estabelecido mediante biópsia por toracoscopia. Optou-se por tratamento com corticosteróide, sem antifúngicos, tendo o paciente respondido bem, com melhora clínico-radiológica após três semanas do início dos sintomas.

The case of a 40-year-old agricultural worker affected by pulmonary adiaspiromycosis is reported. An etiological diagnosis had been established by means of a biopsy via thoracoscopy. Treatment with corticosteroids without antifungal drugs was chosen, and the patient responded well to this, with improvements in clinical and radiological conditions three weeks after the beginning of the symptoms.

Adiaspiromicose pulmonar humana / Human pulmonary adiaspiromycosis

A adiaspiromicose é uma doença fúngica sistêmica que acomete usualmente roedores e raramente atinge o homem. É causada pelo fungo Emmonsia crescens e ocorre após a inalação da forma contagiante (conídios). Embora estas formas não se multipliquem nem se disseminem no organismo humano, induzem uma reação inflamatória crônica granulomatosa de padrão miliar que pode levar a falência respiratória e morte. Apresentamos aqui um caso de adiaspiromicose pulmonar humana em paciente imunocompetente que exibia infiltrado intersticial pulmonar difuso ao exame de imagem e fora diagnosticado mediante biópsia pulmonar.

Adiaspiromycosis is a systemic fungal disease that usually affects rodents and rarely infects humans. It is caused by the fungus Emmonsia crescens and occurs after inhalation of its contagious form (conidia). Although these forms neither multiply nor spread in the human body, they cause a chronic granulomatous inflammatory reaction of miliary pattern, which may lead to respiratory failure and death. In this study we present a case of human pulmonary adiaspiromycosis in an immunocompetent patient that showed a diffuse pulmonary interstitial infiltrate diagnosed by pulmonary biopsy.

Adiaspiromicose humana: relato de um caso tratado com cetoconazol / Human adiaspiromycosis. A report of a case treated with ketoconazole

É descrito um caso de adiaspiromicose humana, da forma pulmonar disseminada, no qual se empregou o cetoconazol. O paciente, oriundo de Goianésia, GO, referia tosse produtiva, dispnéia e emagrecimento. Doente há dois meses, já fizera uso do esquema tríplice tuberculostático, devido a um radiograma do tórax ter acusado lesões sugestivas de tuberculose miliar. Esse tratamento não surtiu o efeito esperado, pelo que foi ele submetido a uma biópsia pulmonar a céu aberto. A medida permitiu o reconhecimento da natureza fúngica da doença. Passou-se, então, ao emprego do cetoconazol, quando o processo já completara três meses de evolução. Dois meses depois, foi o paciente novamente visto, para controle do tratamento: todas as manifestações respiratórias haviam cessado e um novo radiograma mostrou regressão completa das alterações pulmonares. Apesar disso, é discutida a eficácia do cetoconazol contra C. parvum var crescens, tendo-se em conta o fato de o microrganismo não se reproduzir no hospedeiro.

A case of human disseminated pulmonary adiaspiromycosis is reported. The patient, from Goianésia, GO, was admitted to the Brasilia University Hospital, in November 1992, with wet cough, dyspnea and weight loss--manifestations that had appeared two months before. Prior to admission, he had been treated for a suspected miliary tuberculosis, because a chest roentgenogram had shown a diffuse reticulonodular infiltrate in both lungs. This therapy brought no improvement to the patient status. An open chest biopsy was then performed, and the microscopic examination of the lung tissue revealed the fungal nature of the disease. Ketoconazole, 400mg/day, was started and the patient discharged from the hospital. He was seen again two months later: the respiratory manifestations had disappeared and a new chest roentgenogram showed complete resolution of the pulmonary lesions. The usefulness of ketoconazole is, however, questioned, since, as there is no multiplication of the fungus in the host organism--adiaspiromycosis is believed to be, usually, a self-healing disease--the efficacy of this imidazole derivative against the agent in animal tissues remains to be confirmed.

Adiaspiromicose pulmonar disseminada: relato de caso / Disseminated pulmonary adiaspiromycosis: a case report

Relata-se caso de adiaspiromicose causando infiltrado pulmonar retículo-nodular difuso e bilateral, em lavrador de 26 anos. O diagnóstico etiológico foi estabelecido através de biópsia por toracoscopia. Tratado com cetoconazol, o paciente evoluiu bem, retornando às atividades profissionais um mês após a alta.

A case of thoracoscopic lung biopsy proven diffuse human adiaspiromycosis is reported. The patient, a 26-year-old male farm worker presented with a three-week history of fever, sweating, dyspnea and unproductive cough. Radiographic findings were those of granulomatous pulmonary interstitial disease. Treated with ketoconazole he improved very well, resuming work normal activities a month later.
