The systemic capillary leak syndrome: a scarcely known nephrological entity

The idiopathic systemic capillary leak syndrome (SCLS) is a rare life-threatening disorder characterized by periodic episodes of hypovolemic shock, due to plasma leakage from the intravascular to the interstitial space, as reflected by accompanying hypoalbuminemia, hemoconcentration and edema. Here we report the case of a 65-year-old woman affected by SCLS who required aggressive resuscitation with norepinephrine, steroids, albumin and crystalloids. Then, a long-term prophylaxis with a ß(2)-adrenergic receptor agonist and theophylline was started. In conclusion, though SCLS is a rare entity, the associated morbidity and mortality require the physician's awareness to provide timely therapy. Underrecognition in the medical community and rarity of this syndrome have precluded analysis by rational clinical trial designs that are necessary to determine more targeted and adequate therapy. This report is meant to enhance awareness of SCLS in the nephrology community.
