The capillary leak syndrome (CLS) is a rare condition characterized by the onset of hypotension, edema, hemoconcentration and hypoalbuminemia. CLS can be idiopathic (Clarkson's disease) or secondary to various conditions and treatments. Here, we review the clinical and biological features, pathophysiology, causes and treatment of this rare condition. ⋯ Clarification of the pathophysiological mechanisms of CLS is essential to improve the prognosis of this rare disease with more targeted treatments.

French health insurance databases are organized since 2003 into a huge digital data warehouse, the Système national d'information inter-régime de l'assurance maladie (SNIIR-AM). It covers the entire French population (65 million inhabitants). In order to facilitate studies on more frequent conditions, a random sample of 1/97th of national health system beneficiaries has been built since 2005, called the échantillon généraliste des bénéficiaires (EGB). ⋯ All these data are prospectively recorded, individualized, made anonymous and linkable. Consequently, the SNIIR-AM is a very useful data source for epidemiological, pharmacoepidemiological and health economics studies, particularly for rare diseases. The EGB is appropriate for long-term research on more frequent diseases.
