Disease pathophysiology: Systemic capillary leak syndrome is a rare disorder characterized by self-reversing episodes during which the endothelial cells which line the capillaries are thought to separate for a few days, allowing for massive leakage of plasma and other blood components from the blood vessels into neighbouring body cavities and muscles. Systemic capillary leak syndrome usually consists of two phases i.e capillary leak phase and recruitment phase. This leads to swelling. Systemic capillary leak syndrome leads to hypotension, hemoconcentration, and hypoalbuminemia. It is a life threatning syndrome often misdiagnosed with polycythemia, polycythemia vera, or sepsis.
Treatment: Mainly the intravenous administration of saline solution plus hetastarch or albumin and colloids (to increase the remaining blood flow to vital organs like the kidneys), as well as glucocorticoids (steroids like methylprednisolone, to reduce or stop the capillary leak). However, it is important to avoid overly aggressive intravenous fluid administration during this leak phase, because it may cause massive swelling of the extremities and thus serious collateral damage because of induced compartment syndromes.
The patient was diagnosed with SCLCS and treated with therbutaline and aminophylline. Research: Major research is been performed by NORD (National Organization of Rare Disorders) Statistics: Idiopathic systemic capillary leak syndrome is a rare and fatal disease due to the unexplained episodic attacks of capillary leakage of plasma from the intravascular into the interstitial space. The attack consists of three phases, a prodromal phase, peripheral leak phase and recruitment phase. During the peripheral leak phase, generalized edema, mainly in the trunk and extremities, with hemoconcentration and hypoalbuminemia occurs, while usually the visceral organs like lungs, brain, heart and kidneys seem not to be involved. Treatment of the acute phase is supportive, focusing on adequate but not overzealous fluid resuscitation, because pulmonary edema usually occurs in the recruitment phase.
