Systemic Capillary Leakage Syndrome (SCLS) - also known as Clarkson’s sydrome from the name of the clinician observing and reporting it first time few decades ago [1] - is a tricky quite rare syndrome [2-4]: few tens of subjects have been known worldwide, of which 13 have been treated here in Milano at Sacco University Hospital under the responsibility of the late Marco Cicardi, former professor and general director for Clinical Medicine, together with his Assistant Professors, mainly Maddalena Wu also studying correlations with Autonomous Nervous Systems through Hearth Rate Variablity analysis [5], and Gianmarco Podda on the patient bed.

  Causes are still unknown, and obviously there is no economical pharma interest in studying and possibly healing such a rare disease, but there is interest in governmental agencies, like our one, to invest little tax- payer money in order to better understand such pathology, that could also be informative about underlying physiology, as usual. The main evident effect is that, apparently asynchronously within life, repeatedly, and suddenly, capillary bed starts leaking all over the body – as opposite to local inflammatory diseases – almost like a general menstruation not involving just endometrium nor even just females.
