Insights and perspectives into clinical biomarker discovery in pediatric heart failure and congenital heart disease-a narrative review.

ABSTRACT:

Background and objective

Heart failure (HF) in the pediatric population is a multi-factorial process with a wide spectrum of etiologies and clinical manifestations, that are distinct from the adult HF population, with congenital heart disease (CHD) as the most common cause. CHD has high morbidity/mortality with nearly 60% developing HF during the first 12 months of life. Hence, early discovery and diagnosis of CHD in neonates is pivotal. Plasma B-type natriuretic peptide (BNP) is an increasingly popular clinical marker in pediatric HF, however, in contrast to adult HF, it is not yet included in pediatric HF guidelines and there is no standardized reference cut-off value. We explore the current trends and prospects of biomarkers in pediatric HF, including CHD that can aid in diagnosis and management.

Methods

As a narrative review, we will analyze biomarkers with respect to diagnosis and monitoring in specific anatomical types of CHD in the pediatric population considering all English PubMed publications till June 2022.

Key content and findings

We present a concise description of our own experience in applying plasma BNP as a clinical biomarker in pediatric HF and CHD (tetralogy of fallot vs. ventricular septal defect) in the context of surgical correction, as well as untargeted metabolomics analyses. In the current age of Information Technology and large data sets we also explored new biomarker discovery using Text Mining of 33M manuscripts currently on PubMed.

Conclusions

(Multi) Omics studies from patient samples as well as Data Mining can be considered for the discovery of potential pediatric HF biomarkers useful in clinical care. Future research should focus on validation and defining evidence-based value limits and reference ranges for specific indications using the most up-to-date assays in parallel to commonly used studies.

Project description:Biomarkers are increasingly part of assessing and managing heart failure (HF) in adults with congenital heart disease (CHD). To understand the response of cardiac biomarkers with therapy for acute decompensated heart failure (ADHF) and the relationship to prognosis after discharge in adults with CHD. A prospective, observational cohort study with serial blood biomarker measurements. Single-center study in the inpatient setting with outpatient follow-up. Adults (≥18 years old) with CHD admitted with ADHF between August 1, 2019, and March 1, 2020. We measured body mass, Kansas City Cardiomyopathy Questionnaire (KCCQ-12) score, N-terminal pro-B-type natriuretic peptide (NT-proBNP), and high-sensitivity C-reactive protein (hsCRP) at enrollment, discharge, and 1st clinic follow-up visit; soluble suppression of tumorigenicity 2 (sST2) was measured at the first two time points. Univariate regression assessed the association between changes in weight, biomarkers, and changes in KCCQ-12 scores, between enrollment and discharge (ΔHospitalization ) and between discharge and 1st clinical follow-up visit (ΔPost-discharge ). Wilcoxon rank-sum tests assessed the association between change in biomarkers, KCCQ-12 scores, and the composite outcome of cardiovascular death or rehospitalization for ADHF. A total of 26 patients were enrolled. The median age was 51.9 years [IQR: 38.8, 61.2], 13 (54.2%) were women, and median hospital stay was 6.5 days [IQR: 4.0, 15.0] with an associated weight loss of 2.8 kg [IQR -5.1, -1.7]. All three cardiac biomarkers decreased during hospitalization with diuresis while KCCQ-12 scores improved; a greater decrease in sST2 was associated with an improved KCCQ-12 symptom frequency (SF) subdomain score (p = 0.012), but otherwise, there was no significant relationship between biomarkers and KCCQ-12 change. Change in hsCRP and NT-proBNP after discharge was not associated with the composite outcome (n = 8, vs. n = 16 who did not experience the outcome; Δ Post-discharge hsCRP +5.1 vs. -1.0 mg/l, p = 0.061; NT-proBNP +785.0 vs. +130.0 pg/ml, p = 0.220). Serial biomarker measurements respond to acute diuresis in adults with CHD hospitalized for ADHF. These results should motivate further research into the use of biomarkers to inform HF therapy in adults with CHD.

Project description:Background and aimHeart failure in children differs substantially from the adult population. Clinical characteristics of pediatric diastolic heart failure has rarely been reported. In this study, we aimed to summary the causes, clinical features, lab tests, and treatment effect of pediatric diastolic heart failure.MethodsThis study was a single center, retrospective study conducted in Children's Hospital of Chongqing Medical University. Children who were diagnosed with diastolic heart failure (DHF) without systolic heart failure (SHF) between 2006 and 2014 were included. Meanwhile, SHF (without DHF) cases were also collected from 2013 to 2014.ResultsA total of 421 DHF and 42 SHF cases were included. The average age of pediatric DHF was 1.89 ± 3.29 years old, significant younger than that of SHF (4.65 ± 4.90). The top three cardiovascular causes of DHF were complex congenital heart malformations (53.4%), simple congenital heart defect (15.7%), and cardiomyopathy (7.4%). Alternatively, number of cardiomyopathy cases (57.1%) ranked first in SHF group. Simple congenital heart diseases (CHDs) rarely caused SHF. The most common symptom and sign were tachypnea and hepatomegaly in pediatric HF. Symptoms like cyanosis, feeding difficulty, be fidgety, pale, fatigue, and edema were valuable in differential diagnosis of DHF and SHF in children. B-type natriuretic peptide (BNP) increase was found in 36.9% of DHF children, and 60% in SHF patients. Sensitivity of BNP greater than 100 pg/ml in diagnosis of DHF was 0.37, and specificity of it was 0.86. Diastolic function indicators, such as E/A (early wave/late wave) ratio, IVRT (isovolumic relaxation time) were significant recovered after treatment in DHF patients. Less therapeutic benefits were achieved in children with cardiomyopathy induced DHF, in compared with non-cardiomyopathy patients.ConclusionPediatric DHF and SHF were largely different in primary causes, clinical symptoms and signs and short-term prognosis. There was a limit diagnostic value of BNP with 100 pg/ml as cut-off value in pediatric DHF. Larger, multicenter studies of pediatric DHF are required in the future.

Project description:ObjectiveTo quantitatively characterize the pattern of systemic impairment reflected by conventional biomarkers and assess how it relates to clinical outcomes and quality of life among patients hospitalized for heart failure (HF).MethodsPatients hospitalized for HF from 52 hospitals in China were enrolled between 2016 and 2018. They were divided into developing and validating cohorts; the developing cohort was used for calculating the weights of biomarkers and constructing the multi-biomarker panel, while the validating one was used for evaluating the relationship between multi-biomarker points and outcomes. In total, five conventional biomarkers reflecting various pathophysiological processes were included in the panel: N-terminal pro-B type natriuretic peptide, high-sensitivity troponin T, hemoglobin, albumin, and creatinine. The weights of the biomarkers were defined based on their relationship with cardiovascular death, and each patient had a multi-biomarker point ranging from 0 to 12. The primary clinical outcome was cardiovascular death, and the other clinical outcomes included rehospitalization for HF, all-cause death, and all-cause rehospitalization in 1-year. The quality of life was measured using Kansas City Cardiovascular Questionnaire. Multi-variable Cox proportional hazard models were used to assess the risks of clinical outcomes, and generalized linear models were used to evaluate the quality of life.ResultsIn total, 4,693 patients hospitalized for HF were included in this analysis; the median (interquartile range, IQR) age was 67 (57-75) years old and 1,763 (37.6%) were female. The median multi-biomarker point was 5 (IQR, 2-6). There were 18.0% of patients in the low point group (<2), 29.4% in the mid-low point group (2-4), 27.8% in the mid-high point group (5-6), and 24.7% in the high point group (>6). Compared with those in the low point group, the patients in the high point group had a significantly excess risk of cardiovascular death (adjusted hazard ratio: 5.69, 95% CI, 3.33-9.70). Furthermore, patients with higher points were also more prone to worse quality of life.ConclusionSystemic impairment reflected by abnormal conventional biomarker values was common amongst patients hospitalized for HF and had substantially cumulative adverse influence on clinical outcomes and quality of life.
