Atypical hemolytic uremic syndrome in children: complement mutations and clinical characteristics
Item does not contain fulltextBACKGROUND: Mutations in complement factor H (CFH), factor I (CFI), factor B (CFB), thrombomodulin (THBD), C3 and membrane cofactor protein (MCP), and autoantibodies against factor H (alphaFH) with or without a homozygous deletion in CFH-related protein 1 and 3 (CFHR1/3) predispose development of atypical hemolytic uremic syndrome (aHUS). METHODS: Different mutations in genes encoding complement proteins in 45 pediatric aHUS patients were retrospectively linked with clinical features, treatment, and outcome. RESULTS: In 47% of the study participants, potentially pathogenic genetic anomalies were found (5xCFH, 4xMCP, and 4xC3, 3xCFI, 2xCFB, 6xalphaFH, of which five had CFHR1/3); four patients carried combined genetic defects or a mutation, together with alphaFH. In the majority (87%), disease onset was preceeded by a triggering event; in 25% of cases diarrhea was the presenting symptom. More than 50% had normal serum C3 levels at presentation. Relapses were seen in half of the patients, and there was renal graft failure in all except one case following transplant. CONCLUSIONS: Performing adequate DNA analysis is essential for treatment and positive outcome in children with aHUS. The impact of intensive initial therapy and renal replacement therapy, as well as the high risk of recurrence of aHUS in renal transplant, warrants further understanding of the pathogenesis, which will lead to better treatment options.01 augustus 201
Dealing with Ebstein's anomaly
Item does not contain fulltextEbstein's anomaly is a complex congenital disorder of the tricuspid valve. Presentation in neonatal life and (early) childhood is common. Disease severity and clinical features vary widely and require a patient-tailored treatment. In this review, we describe the natural history of children and adolescents with Ebstein's anomaly, including symptoms and signs presenting at diagnosis. Current classification strategies of Ebstein's anomaly are discussed. We report on diagnostic methods for establishing the severity of disease that might enhance decision on the timing of surgical intervention. Furthermore, we describe different surgical options for severely ill neonates and multiple surgical interventions after infancy. Only with ample knowledge and understanding of the above, this complex and diverse group of patients can be correctly treated in order to improve not only duration, but also quality of life
Atypical hemolytic uremic syndrome in children : complement mutations and clinical characteristics
Emerging clinical applications of strain imaging and three-dimensional echocardiography for the assessment of ventricular function in adult congenital heart disease
Management of congenital heart disease (CHD) in adults (ACHD) remains an ongoing challenge due to the presence of residual hemodynamic lesions and development of ventricular dysfunction in a large number of patients. Echocardiographic imaging plays a central role in clinical decision-making and selection of patients who will benefit most from catheter interventions or cardiac surgery.. Recent advances in both strain imaging and three-dimensional (3D)-echocardiography have significantly contributed to a greater understanding of the complex pathophysiological mechanisms involved in CHD. The aim of this paper is to provide an overview of emerging clinical applications of speckle-trading imaging and 3D-echocardiography in ACHD with focus on functional assessment, ventriculo-ventricular interdependency, mechanisms of electromechanical delay, and twist abnormalities in adults with tetralogy of Fallot (TOF), a systemic RV after atrial switch repair or in double discordance ventricles, and in those with a Fontan circulation
Paediatric Ebstein's anomaly: How clinical presentation predicts mortality
Background Forecasting the prognosis of a child when diagnosed with Ebstein's anomaly is difficult. We, therefore, studied which factors at the time of diagnosis are associated with death during childhood. Methods All consecutive patients (0-18 years) diagnosed with Ebstein's anomaly in the Netherlands between 1980 and 2014 were included. Survival curves were obtained using the Kaplan-Meier method. By using the Cox proportional hazard model, we analysed the factors (at diagnosis) that were associated with death. Results We included 176 patients. Thirty-one patients (18%) died before the age of 18 years. The 1-year survival was 84% and remained stable at 82% from 35 months after diagnosis and onwards. Modified Ross Heart Failure Class 4 at the time of diagnosis was the most important risk factor for death during childhood (HR 12.5, 95% CI 4.4 to 35.9). Furthermore, diagnosis in the neonatal period (HR 4.2, 95% CI 1.5 to 12.0), severe tricuspid valve regurgitation (HR 2.4, 95% CI 1.2 to 5.0), severe right ventricular outflow tract obstruction (HR 3.7, 95% CI 1.8 to 7.7) and a patent ductus arteriosus (HR 2.8, 95% CI 1.3 to 6.0) at the time of diagnosis were univariately associated with death. Multivariable analysis showed that presentation with Heart Failure Class 4 and a ventricular septal defect is the strongest predictor of death in childhood and adolescence. Conclusion Patients with Ebstein's anomaly presenting with Heart Failure Class 4 and a ventricular septal defect have a high risk of death during childhood
Comprehensive Evaluation of Pediatric Patients with Ebstein Anomaly Requires Both Echocardiography and Cardiac Magnetic Resonance Imaging
With the trend towards childhood surgery in patients with Ebstein anomaly (EA), thorough imaging is crucial for patient selection. This study aimed to assess biventricular function by echocardiography and cardiac magnetic resonance (CMR) and compare EA severity classifications. Twenty-three patients (8–17 years) underwent echocardiography and CMR. Echocardiographic parameters included tricuspid annular plane systolic excursions (TAPSE), fractional area change of the functional right ventricle (fRV-FAC), fRV free wall peak systolic myocardial velocity (fRVs’), and tricuspid regurgitation (TR). End-diastolic and end-systolic volume (EDV resp. ESV), fRV- and LV ejection fraction (EF) and TR were obtained by CMR. EA severity classifications included displacement index, Celermajer index and the total-right/left-volume index. Median fRV-FAC was 38% (IQR 33–42). TAPSE and fRVs’ were reduced in 39% and 75% of the patients, respectively. Echocardiographic TR was visually graded as mild, moderate, or severe in nine, six and eight patients, respectively. By CMR, median fRVEF was 49% (IQR 36–58) and TR was graded as mild, moderate, or severe in nine, twelve and two patients, respectively. In 70% of cases, fRV-EDV was higher than LV-EDV. LVEF was decreased in 17 cases (74%). There was excellent correlation between echocardiography-derived fRV-FAC and CMR-derived fRVEF (rho = 0.812, p < 0.001). While echocardiography is a versatile tool in the complex geometry of the Ebstein heart, it has limitations. CMR offers a total overview and has the advantage of reliable volume assessment of both ventricles. Comprehensive evaluation of pediatric patients with EA may therefore require a synergistic implementation of echocardiography and CMR
Health-related quality of life, emotional and behavioral problems in children and adolescents with ebstein anomaly
Background: Due to the improved survival rates of children and adolescents with congenital heart disease (CHD), more attention is now being direc-ted towards their health-related quality of life (HRQoL), emotional and behavioral problems. Ebstein anomaly (EA) is a rare CHD with a broad clinical spectrum. The aim of the current study is to evaluate self-and proxy-reported HRQoL and emotional and behavioral problems in children and adolescents with EA. Methods: In this cross-sectional, multicenter study, we included EA patients (aged 8–17 years), who underwent routine clinical assessments in Dutch university hospitals between May 2017 and March 2019. The Generic Pediatric Quality of Life Inventory 4.0 (for ages 8–12/13–17years)wasusedtoassessHRQoL. The Child Behavior Checklist, Youth Self-Report and Teacher’s ReportForm were completed to measure emotional and behavioral problems. Results: Ques-tionnaires for thirty-eight patients (median age: 13 years; 48% male) were completed by patients themselves, parents and teachers. Compared to normative data, self-reported HRQoL was not significantly impaired, except for social functioning in children aged 8–12 years. Gender, severity of tricuspid regurgitation or previous surgery did not predict HRQoL. Parents reported significantly more internalizing (anxiety/depression), attention and thought problems in children with EA. These problems, however, were not reported by adolescents themselves. School teachers reported significantly fewer externalizing problems compared to the norm. Conclusions: Overall, despite satisfactory HRQoL, children and adolescents show emotional and behavioral problems. We recommend routine HRQoL and psychological assessment to screen for less apparent internalizing and psychosocial problems
