Systemic capillary leak syndrome is a rare condition, characterized by hypotension, edema, hemoconcentration and hypoalbuminemia. We describe 2 episodes of systemic capillary leak syndrome, following influenza A virus infection, occurring during 2 subsequent influenza seasons, in an 8-year-old boy.

Background: Hemorrhagic shock (HS) corresponds to absolute hypovolemia creating an imbalance between oxygen supply and consumption. This causes an impaired hemostasis, a systemic inflammatory response, and microvascular permeability which can lead to multiple organ failure (MOF). There is no specific treatment for the endothelial dysfunction that plays a major role in the evolution towards MOF.

A circular shunt, initially described by Shone et al. in 1962, refers to abnormal blood recirculation through complete intracardiac or intra- and extracardiac communications, bypassing the capillary beds. This pathophysiological condition is most commonly associated with complex congenital heart defects, such as Ebstein's malformation, pulmonary atresia, Gerbode defect, and so on.

We investigated whether an anti-inflammatory lipid metabolite named 5,6-DiHETE reduces vascular permeability by inhibiting TRPV4 channels in vivo. In wild-type (WT) mice, histamine-induced dye extravasation was reduced by pre-administration of 5,6-DiHETE. In TRPV4-deficient mice, extravasation and histamine-induced edema were already reduced, and 5,6-DiHETE had no additional effect.

Systemic capillary leak syndrome (SCLS) is a rare life-threatening disorder due to profound vascular leak. The trigger and the cause of the disease are currently unknown and there is no specific treatment. Here, we identified a rare heterozygous splice-site variant in the TLN1 gene in a familial SCLS case, suggestive of autosomal dominant inheritance with incomplete penetrance.

Purpose: Denileukin diftitox (DD)-cxdl is a fusion protein comprising diphtheria toxin fragments A and B and human interleukin-2. This phase III, multicenter, open-label, single-arm registrational trial evaluated the efficacy and safety of DD-cxdl in patients with relapsed/refractory (R/R) cutaneous T-cell lymphoma (CTCL).
Patients And Methods: In the main study, which followed a dose-finding lead-in, DD-cxdl was administered intravenously daily (5 days; 9 µg/kg/d once daily) every 21 days for up to eight cycles.
