This case vignette relates the unknown association between systemic capillary leak syndrome, namely Clarkson's syndrome, and acute cardiac dysfunction. 'Central extra-corporeal life support (ECLS)' was needed for the management of an intractable cardiogenic shock. The acute cardiac condition completely resolved within few days. Pathology showed diffuse interstitial edema within the myocardium suggestive of cardiac involvement of the disease. ...[more]

Project description:BackgroundSystemic capillary leak syndrome (SCLS) is a potentially fatal disorder characterized by relapses of hypovolemic shock episodes.Case summaryWe present a case of a 58-year-old man who presented to the Emergency Department with a history of recurrent episodes of syncope in the last hours. A few days before medical contact the patient complained of sore throat, fever, and flu-like symptoms. He was initially admitted with a diagnosis of suspected myopericarditis. Forty-eight hours later, the haemodynamic status suddenly deteriorated to a mixed cardiogenic and shock; an endomyocardial biopsy showed localized inflammatory infiltrates and areas of necrosis of cardiomyocytes with positive viral search for parvovirus B19 (PVB19), therefore the patient was treated with methylprednisolone pulses. Based on the concurrent presence of the typical triad of hypotension, hypoalbuminaemia, and haemoconcentration we suspected systemic leak capillary syndrome potentially triggered by the PVB19 infection with acute myocarditis. The clinical conditions further deteriorated with rhabdomyolysis and acute kidney injury: we started continuous veno-venous haemofiltration adding a cytokines adsorber. In the following hours, we observed a significant clinical improvement. The patient was discharged 1 month later and 5 months after discharge he experienced a new attack of SCLS, this time without myocardial involvement and with prompt symptoms resolution.ConclusionSystemic capillary leak syndrome is a potentially fatal disorder: early recognition of this entity and prompt initiation of supportive therapy are warranted, therefore, it is paramount that an emergency physician thinks of SCLS in patients with signs of cardiogenic shock and the classical triad of hypotension, hypoalbuminia, and haemoconcentration.

Project description:The idiopathic systemic capillary leak syndrome (ISCLS) is a rare disorder, characterized by recurrent attacks of hypotension, hypoalbuminemia, and hemoconcentration, which is often misdiagnosed due to overlapping features with other diseases. Even though cerebral involvement is uncommon, a broad awareness is crucial, because of its life-threatening character.

Project description:Adult subjects with systemic capillary leak syndrome (SCLS) present with acute and recurrent episodes of vascular leak manifesting as severe hypotension, hypoalbuminemia, hemoconcentration, and generalized edema. We studied clinical disease characteristics, serum cytokine profiles, and treatment modalities in a cohort of children with documented SCLS. Six children with SCLS were recruited from the United States, Australia, Canada, and Italy. Serum cytokines from SCLS subjects and a group of 10 healthy children were analyzed. Children with SCLS (aged 5-11 years old) presented with at least 1 acute, severe episode of hypotension, hypoalbuminemia, and hemoconcentration in the absence of underlying causes for these abnormalities. In contrast to what is observed in adult SCLS, identifiable infectious triggers precipitated most episodes in these children, and none of them had a monoclonal gammopathy. We found elevated levels of chemokine (C-C motif) ligand 2 (CCL2), interleukin-8, and tumor necrosis factor ? in baseline SCLS sera compared with the control group. All patients are alive and well on prophylactic therapy, with 4 patients receiving intravenous or subcutaneous immunoglobulins at regular intervals. The clinical manifestations of pediatric and adult SCLS are similar, with the notable exceptions of frequent association with infections and the lack of monoclonal gammopathy. Prophylactic medication, including high dose immunoglobulins or theophylline plus verapamil, appears to be safe and efficacious therapy for SCLS in children.

Project description:Systemic capillary leak syndrome (SCLS; Clarkson disease) is a rare orphan disorder characterized by transient yet recurrent episodes of hypotension and peripheral oedema due to diffuse vascular leakage of fluids and proteins into soft tissues. Humoral mediators, cellular responses and genetic features accounting for the clinical phenotype of SCLS are virtually unknown. Here, we searched for factors altered in acute SCLS plasma relative to matched convalescent samples using multiplexed aptamer-based proteomic screening. Relative amounts of 612 proteins were changed greater than twofold and 81 proteins were changed at least threefold. Among the most enriched proteins in acute SCLS plasma were neutrophil granule components including bactericidal permeability inducing protein, myeloperoxidase and matrix metalloproteinase 8. Neutrophils isolated from blood of subjects with SCLS or healthy controls responded similarly to routine pro-inflammatory mediators. However, acute SCLS sera activated neutrophils relative to remission sera. Activated neutrophil supernatants increased permeability of endothelial cells from both controls and SCLS subjects equivalently. Our results suggest systemic neutrophil degranulation during SCLS acute flares, which may contribute to the clinical manifestations of acute vascular leak.

Project description:The Systemic Capillary Leak Syndrome (SCLS) is an extremely rare, orphan disease that resembles systemic anaphylaxis. The disorder is characterized by repeated, transient, and seemingly unprovoked episodes of hypotensive shock and peripheral edema due to transient endothelial hyperpermeability. SCLS is often accompanied by a monoclonal gammopathy of unknown significance (MGUS). Using Affymetrix Single Nucleotide Polymorphism (SNP) microarrays, we performed the first genome-wide SNP analysis of SCLS in a cohort of 12 disease subjects and 18 controls. Exome capture sequencing was performed on genomic DNA from nine of these patients as validation for the SNP-chip discoveries and de novo data generation. We identified candidate susceptibility loci for SCLS, which included a region flanking CAV3 (3p25.3) as well as SNP clusters in PON1 (7q21.3), PSORS1C1 (6p21.3), and CHCHD3 (7q33). Among the most highly ranked discoveries were gene-associated SNPs in the uncharacterized LOC100130480 gene (rs6417039, rs2004296). Top case-associated SNPs were observed in BTRC (rs1235580, 3rs4436485), ARHGEF18 (rs11668246), CDH13 (rs4782779), and EDG2 (rs12552348), which encode proteins with known or suspected roles in B cell function and/or vascular integrity. SNPs that were significantly associated with SCLS by microarray analysis were also detected and validated by exome deep sequencing. Functional annotation of highly ranked SNPs revealed enrichment of cell projections, cell junctions and adhesion, and molecules containing pleckstrin homology, Ras/Rho regulatory, and immunoglobulin Ig-like C2/fibronectin type III domains, all of which involve mechanistic functions that correlate with the SCLS phenotype. These results highlight SNPs with potential relevance to SCLS. Our study cohort included 12 patients with SCLS. The control group included 17 age, sex and ethnicity-matched healthy donors (including two relatives of SCLS patients), and a reference sample supplied by the SNP-chip manufacturer (Affymetrix), for which age information was not available. Affymetrix SNP arrays were performed according to the manufacturer's directions on DNA extracted from purified B lymphocytes.

Project description:ObjectiveThe term Idiopathic Systemic Capillary Leak Syndrome (ISCLS) refers to an uncommon condition of severe distributive shock, resulting from an abrupt shift of fluids and proteins from the intravascular to the interstitial compartment. We hypothesise that the autonomic nervous system (ANS) fails in regulating the response to hypovolemia in acute ISCLS and that ANS variables characterise the progression to the recovery.DesignProspective cohort study of patients admitted to ICU for severe ISCLS flares.SettingSingle, referral center in Italy for ISCLS.PatientsAnalysis of cardiovascular signals recorded during seven severe ISCLS attacks and one prodromal period in five patients.InterventionsANS was studied non-invasively by means of heart rate variability (HRV) and blood pressure variability analysis, as an estimation of vagal and sympathetic modulation directed to the heart and vessels. Heart rate and systolic arterial pressure (SAP) variability were also used to assess baroreflex sensitivity. ANS variables were measured during the subsequent phases which characterise ISCLS flares, namely the acute phase, the post-acute phase, and the recovery phase.Measurements and main resultsHRV was severely depressed during the acute phase accounting for the loss of ANS modulation during massive capillary extravasation. This phase was characterised by shock and impaired baroreflex control, which allowed SAP to oscillate driven by respiratory activity. Impending shock and transition from shock to a post-acute phase were marked by change of baroreflex spectral variables. The baroreflex control was fully restored during recovery.ConclusionsANS modulation and baroreflex control are severely impaired during the acute haemodynamic instability which characterises ISCLS crises and their progressive restoration may be a clue of improvement. ANS indices during ISCLS flares might serve as useful biomarkers, able to timely announce the transition from one phase to the subsequent one, thus helping to adapt therapy accordingly.

Project description:Systemic capillary leak syndrome (SCLS) is a rare disease characterized by shock caused by capillary hyperpermeability. The disease can occur in cancer patients and effective therapeutic strategies have not been established yet. The aim of the study was to analyze the clinical and laboratory data, treatment modalities, and mortality rate of patients and to identify contributing factors leading to mortality of SCLS in cancer. We searched MEDLINE (inception to July 2018) and of 4612 articles, we identified 62 case reports on SCLS associated with cancer or cancer-related drugs in a total of 53 articles. SCLS was associated with cancer itself in 43.6%, with anti-cancer agents in 51.6% and bone marrow transplantation (BMT) in 4.8%. Among anti-cancer agents, granulocyte-colony stimulating factor (G-CSF) was the most frequently associated drug (14.6%), followed by interleukin (IL)-2 (11.4%). The most common associated malignancies were hematologic (61.3%) with non-Hodgkin lymphoma (22.7%) and multiple myeloma (12.9%) being the leading causes. Common symptoms and signs included dyspnea (27.4%), edema (67.7%), hypotension (32.2%), pleural effusion (29.0%), ascites (22.7%), oliguria (22.7%), and weight gain (21.0%). Patients with SCLS were treated with steroids (59.7%), volume replacement (33.8%), diuretics (24.2%), inotropes (9.6%), methylxanthines (12.8%), ?2 agonists (4.8%), while intravenous immunoglobulins (IVIG) were administered in 2 patients (3.2%) only. Among sixteen deaths during follow-up, four were directly attributed to SCLS. Hematologic malignancies were associated with an increased risk for mortality (hazard ratio (HR) 8.820, 95% confidence interval (CI) 1.126?69.063, p = 0.038). Taken together, SCLS can be one important adverse event in cancer patients and careful monitoring of fluid volume is required in the management of SCLS.

Project description:The Systemic Capillary Leak Syndrome (SCLS) is an extremely rare and potentially life-treating vascular disorder of unknown etiology. SCLS is characterized by dramatic and transient episodes of hypotensive shock and edema due to plasma leakage into peripheral tissues. The disorder has garnered increased attention during the last several years because of the resemblance of its initial presentation to more common disorders such as systemic anaphylaxis, sepsis, and acute infections with the Ebola/Marburg family of filoviruses. Although approximately 70-80% of patients with SCLS have a concurrent monoclonal gammopathy of unknown significance (MGUS), any contribution of the paraprotein to acute flares is unknown. To identify circulating factors that contribute to the onset of acute SCLS crises, we performed transcriptomic profiling of paired peripheral blood mononuclear cell fractions obtained from patients during acute attacks and convalescent intervals using microarray. 61 genes were significantly up- or downregulated more than 2.5 fold in acute samples relative to baseline. One of the most upregulated genes was ADM, which encodes the vasoactive peptide adrenomedullin. The ADM surrogate pro-ADM was markedly elevated in SCLS acute sera compared to remission samples or sera from healthy controls. Monocytes and endothelial cells (ECs) from SCLS subjects expressed significantly more ADM in response to proinflammatory stimuli compared to healthy control cells. Application of ADM to ECs exerted protective effects on vascular barrier function. These results suggest a pathogenic contribution of ADM to the profound pressor-resistant hypotension that characterizes the initial stages of SCLS.

Project description:ObjectiveTo determine clinical features, natural history, and outcome of a well-defined cohort of 25 consecutive patients with idiopathic systemic capillary leak syndrome (SCLS) evaluated at a tertiary care center.Patients and methodsRecords of patients diagnosed as having SCLS from November 1, 1981, through April 30, 2008, were reviewed. Descriptive statistics were used to analyze patient demographics, clinical features, complications, and therapeutic interventions.ResultsOf the 34 patients whose records were reviewed, 25 fulfilled all diagnostic criteria for SCLS. The median age at diagnosis of SCLS was 44 years. Median follow-up of surviving patients was 4.9 years, and median time to diagnosis from symptom onset was 1.1 years (interquartile range, 0.5-4.1 years). Flulike illness or myalgia was reported by 14 patients (56%) at onset of an acute attack of SCLS, and rhabdomyolysis developed in 9 patients (36%). Patients with a greater decrease in albumin level had a higher likelihood of developing rhabdomyolysis (p=.03). Monoclonal gammopathy, predominantly of the IgG-κ type, was found in 19 patients (76%). The progression rate to multiple myeloma was 0.7% per person-year of follow-up. The overall response rate to the different therapies was 76%, and 24% of patients sustained durable (>2 years) complete remission. The estimated 5-year overall survival rate was 76% (95% confidence interval, 59%-97%).ConclusionSystemic capillary leak syndrome, a rare disease that occurs in those of middle age, is usually diagnosed after a considerable delay from onset of symptoms. The degree of albumin decrement during an attack correlates with development of rhabdomyolysis. A reduction in the frequency and/or the severity of attacks was seen in nearly three-fourths of patients who were offered empirical therapies. The rate of progression to multiple myeloma appears to be comparable to that of monoclonal gammopathy of undetermined significance.
