ABSTRACT

Os autores relatam o caso de uma paciente com estenose de uretra que desenvolveu pneumonia eosinofílica crônica secundária ao uso prolongado de nitrofurantoína como profilaxia para infecção urinária de repetição. A paciente havia sido submetida a uma biópsia pulmonar a céu aberto. É dada ênfase aos achados da tomografia computadorizada de alta resolução do tórax, já que, embora as alterações pulmonares associadas à toxicidade da nitrofurantoína geralmente sejam basais e bilaterais, no caso aqui descrito, as lesões de natureza interstício-alveolares situaram-se nas regiões subpleurais dos lobos superiores. Esses achados, por si só, são muito sugestivos de pneumonia eosinofílica crônica. O diagnóstico foi confirmado por meio da revisão da biópsia.


The authors report the case of a female patient who developed chronic eosinophilic pneumonia secondary to long-term use of nitrofurantoin for prophylaxis of recurrent urinary tract infections due to urethral stenosis. On high-resolution computed tomography scans, the pulmonary reaction to nitrofurantoin most commonly manifests as an interstitial-alveolar pattern in both lung bases. However, in this case, the alterations were most pronounced in the periphery of the upper lobes. In itself, this tomographic profile is strongly indicative of chronic eosinophilic pneumonia. The patient had previously been submitted to an open lung biopsy. The diagnosis of chronic eosinophilic pneumonia was confirmed through a review of the biopsy.

ABSTRACT

We report a case of an elderly woman who developed a severe, chronic pulmonary reaction to nitrofurantoin therapy that she had taken continuously for three years to prevent urinary tract infections. The patient was taking no other drug known to cause lung disease but the diagnosis was delayed by failure to recognize the association between nitrofurantoin and adverse drug reactions affecting the lung. When originally seen, the patient was unable to care for herself due to dyspnea. Bronchoscopy with biopsy ruled out other causes of her pulmonary disease. Immediate withdrawal of nitrofurantoin led to substantial, sustained improvement and disappearance of symptoms over several months without administration of corticosteroids. Nitrofurantoin toxicity should always be considered in any person taking that drug who develops bilateral infiltrates.

ABSTRACT

A infecçäo do trato urinário é a infecçäo mais freqüente na gestaçäo. Acomete, aproximadamente, 10 por cento das mulheres durante a gravidez. Ressaltam-se os fatores predisponentes, como as modificaçöes anatômicas e funcionais decorrentes da gestaçäo; é de suma importância a urocultura de rotina no pré-natal. O tratamento deve ser imediato quando se faz o diagnóstico clínico ou laboratorial. A farmacocinética das drogas deve ser conhecida pelo clínico, bem como seus efeitos sobre o binômio materno-fetal. Os dados säo conflitantes em relaçäo ao melhor esquema terapêutico, quer seja dose única, de curta duraçäo (três dias) ou longa duraçäo (sete a 14 dias). Todavia, o uso de dose única é restrito às infecçöes utinárias näo-complicadas. A pielonefrite exige terapêutica parenteral, seguida por esquema oral de longa duraçäo e, por vezes, por antibioticoprofilaxia até o puerpério imediato. Independente do esquema, o seguimento destas pacientes, com urocultura até o puerpério, é imprescindível para a profilaxia das recidivas ou recorrências.
