Bilioptysis associated with alcohol hepatitis without evidence of bronchobiliary fistula: A rare case report

The presence of bilirubin in the sputum is uncommon but, when present, is most commonly associated with the presence of bronchobiliary fistula, which could be associated with a number of underlying conditions. However, the finding of bilioptysis without bronchobiliary fistula is uncommon, with one associated mechanism postulated to involve increased capillary membrane permeability. This case report describes a patient presenting with bilioptysis while being medically managed with prednisolone for severe alcoholic hepatitis. The patient developed hospital‐acquired pneumonia during her hospitalization associated with bilioptysis, resulting in progressive respiratory failure requiring ventilatory support. Alcohol‐related pulmonary dysfunction alters pulmonary immune processes, leading to increased susceptibility to pulmonary infection and disrupting the basal alveolar epithelial membrane, thus increasing permeability. This patient's findings were in the absence of a bronchobiliary or bronchopleural fistula, and we hypothesize that increased capillary membrane permeability was contributory to the bilioptysis in this case.
