title: Pleural Effusion Developing in Two Patients on Continuous Ambulatory Peritoneal Dialysis.
abstract: Two patients with end-stage-renal-disease on continuous ambulatory peritoneal dialysis (CAPD) presented with pleural effusions. The aspirated fluid was categorised as transudate, based on alkaline pH, low protein and lactic dehydrogenase level. A striking feature of the pleural fluid was, its very high glucose content that resulted from translocation of dextrose containing peritoneal dialysate into the pleural space via a pleuroperitoneal connection. One patient was transferred to hemodialysis, which led to complete resolution of pleural effusion. The other patient was switched to automated peritoneal dialysis, using small dwell volumes with consequent reduction in size of the pleural effusion. Pleuroperitoneal leak should always be considered in the differential diagnosis of pleural effusion in CAPD patients. Although isotopic peritoneography can demonstrate reflux of the tracer in the pleural space, measurement of pleural fluid glucose is a simpler and reliable way of diagnosing pleuroperitoneal communication.
