ABSTRACT

OBJETIVO: Determinar a prevalência da doença do refluxo gastroesofágico (DRGE) e sua apresentação clínica, além do perfil funcional do esôfago em pacientes com fibrose pulmonar idiopática (FPI). MÉTODOS: Foram avaliados prospectivamente 28 pacientes com FPI. Os pacientes foram submetidos à esofagomanometria estacionária, pHmetria de 24 h e testes de função pulmonar, assim como responderam a questionários sobre sintomas e qualidade de vida em DRGE. RESULTADOS: A prevalência de DRGE foi de 35,7 por cento. Os pacientes foram divididos em dois grupos: grupo DRGE+ (pHmetria anormal; n = 10), e grupo DRGE- (pHmetria normal; n = 18). No grupo DRGE+, 77,7 por cento dos pacientes apresentavam pelo menos um sintoma típico de DRGE. Nesse grupo de pacientes, 8 (80 por cento) apresentaram refluxo em posição supina, e 5 (50 por cento) apresentaram refluxo exclusivamente nessa posição. Nos grupos DRGE+ e DRGE-, respectivamente, 5 (50,0 por cento) e 7 (38,8 por cento) dos pacientes apresentaram hipotonia do esfíncter esofágico inferior, assim como 7 (70,0 por cento) e 10 (55,5 por cento) apresentaram hipomotilidade esofágica. Não houve diferenças significativas entre os grupos quanto a características demográficas, função pulmonar, apresentação clínica ou achados manométricos. CONCLUSÕES: A prevalência de DRGE nos pacientes com


OBJECTIVE: To determine the prevalence of gastroesophageal reflux disease (GERD) and to evaluate its clinical presentation, as well as the esophageal function profile in patients with idiopathic pulmonary fibrosis (IPF). METHODS: In this prospective study, 28 consecutive patients with IPF underwent stationary esophageal manometry, 24-h esophageal pH-metry and pulmonary function tests. All patients also completed a symptom and quality of life in GERD questionnaire. RESULTS: In the study sample, the prevalence of GERD was 35.7 percent. The patients were then divided into two groups: GERD+ (abnormal pH-metry; n = 10) and GERD- (normal pH-metry; n = 18). In the GERD+ group, 77.7 percent of the patients presented at least one typical GERD symptom. The pH-metry results showed that 8 (80 percent) of the GERD+ group patients had abnormal supine reflux, and that the reflux was exclusively in the supine position in 5 (50 percent). In the GERD+ and GERD- groups, respectively, 5 (50.0 percent) and 7 (38.8 percent) of the patients presented a hypotensive lower esophageal sphincter, 7 (70.0 percent) and 10 (55.5 percent), respectively, presenting lower esophageal dysmotility. There were no significant differences between the groups regarding demographic characteristics, pulmonary function, clinical presentation or manometric findings. CONCLUSIONS: The prevalence of GERD in the patients with IPF was high. However, the clinical and functional characteristics did not differ between the patients with GERD and those without.
