ABSTRACT

OBJETIVO: Verificar a ocorrência da síndrome hepatopulmonar (SHP) em pacientes cirróticos candidatos a transplante de fígado; comparar as características demográficas, clínicas, laboratoriais e espirométricas, resultados de ecocardiografia, análise de gases arteriais e da gravidade da doença hepática nos pacientes com e sem SHP; e descrever a ocorrência de SHP no subgrupo de pacientes com cirrose associada à esquistossomose mansônica (doença hepática mista). MÉTODOS: Entre janeiro e novembro de 2007, foram avaliados 44 pacientes inscritos no Ambulatório de Transplante Hepático do Hospital das Clínicas da Universidade Federal de Pernambuco, em Recife (PE). Os critérios diagnósticos para SHP foram a presença de dilatações vasculares intrapulmonares, identificadas por ecocardiografia transtorácica, assim como diferença alveoloarterial de oxigênio > 15 mmHg ou PaO2 < 80 mmHg. RESULTADOS: A idade média foi 52 anos, e 31 pacientes (70 por cento) eram do sexo masculino. A causa mais frequente de cirrose foi uso de etanol. A esquistossomose esteve presente em 28 pacientes (64 por cento). Dos 44 pacientes, 20 (45,5 por cento) foram diagnosticados com SHP. Não foram observadas diferenças significativas em relação às características estudadas. No subgrupo de pacientes com cirrose associada à esquistossomose, 10/28 (35,7 por cento) receberam o diagnóstico de SHP. CONCLUSÕES: A SHP apresentou elevada prevalência nesta população estudada, não sendo observadas associações entre a sua ocorrência e as variáveis analisadas.


OBJECTIVE: To determine the occurrence of hepatopulmonary syndrome (HPS) in patients with cirrhosis who are candidates for liver transplantation; to compare demographic, clinical, laboratory, and spirometric characteristics, as well as echocardiography results, arterial blood gas analysis, and severity of liver disease between the groups of patients with and without HPS; and to describe the occurrence of HPS in the subgroup of patients with cirrhosis and schistosomiasis mansoni (mixed liver disease). METHODS: Between January and November of 2007, we evaluated 44 patients under treatment at the Liver Transplant Outpatient Clinic of the Federal University of Pernambuco Hospital das Clínicas, in the city of Recife, Brazil. The diagnostic criteria for HPS were intrapulmonary vascular dilatation, identified by transthoracic echocardiography, and an alveolar-arterial oxygen tension difference > 15 mmHg or a PaO2 < 80 mmHg. RESULTS: The mean age of the patients was 52 years, and 31 patients (70 percent) were male. The most common cause of cirrhosis was alcohol use. Schistosomiasis was present in 28 patients (64 percent). Of the 44 patients, 20 (45.5 percent) were diagnosed with HPS. No significant differences were found between those patients and the patients without HPS in terms of any of the characteristics studied. Of the 28 patients with cirrhosis and schistosomiasis, 10 (35.7 percent) were diagnosed with HPS. CONCLUSIONS: In the population studied, HPS was highly prevalent and did not correlate with any of the variables analyzed.
