Capillary leak syndrome (CLS) is a rare, life-threatening disorder characterized by recurrent episodes of fluid leaking from the blood vessels into the surrounding tissues, hypotension, oedema, haemoconcentration and hypoalbuminemia.1 CLS can be idiopathic (Clarkson’s disease) or secondary to various conditions and treatments.1 Secondary CLS typically results from, systemic autoimmune disorders, viral infections, malignant haematological diseases and treatments such as chemotherapies and therapeutic growth factors.1 Diagnosis of idiopathic CLS is made by exclusion of secondary diseases, especially as a serum monoclonal immunoglobulin is present, or when there is a relapsing disease, no initial lung involvement or preserved consciousness despite low blood pressure.1 Prophylactic treatment of Clarkson’s disease with intravenous immunoglobulin may reduce the frequency and severity of attacks and may improve survival.
