Comparison of lipid profile values in pediatric patients with cyanotic and acyanotic congenital heart disease

Background Incidence of congenital heart disease (CHD) is about 0.8% of every child born. This heart defect is associated with dyslipidemia in children. Lipid profiles examination in patients with CHD can be used to determine risk factors for atherosclerosis.
 Objective To examine differences in lipid profiles in children with cyanotic and acyanotic CHD.
 Methods This was a cross-sectional study on 60 pediatric CHD patients at Haji Adam Malik Hospital, Medan, North Sumatera, from December 2020 to March 2021. Subjects were included by consecutive sampling. Data of patient’s age, gender, weight, height, complete blood count, blood glucose, and lipid profiles were recorded. Unpaired T-test analysis and Mann-Whitney test were then performed to analyze variables in cyanotic and acyanotic CHD patients.
 Results Of a total of 60 CHD children, 26 subjects had a diagnosis of cyanotic CHD and 34 subjects had a diagnosis of acyanotic CHD. The most common cause of cyanotic CHD was tetralogy of Fallot (76.9%), while the most common cause of acyanotic CHD were ventricular septal defect and patent ductus arteriosus (32.4% each). Analysis of lipid profiles on both groups revealed that low density lipoprotein (LDL) was significantly lower in the cyanotic group than in the acyanotic group (P<0.05). However, other lipid profile values, were not significantly different between groups. In addition, there was no significant difference in incidence of dyslipidemia between cyanotic and acyanotic CHD.
 Conclusion Low density lipoprotein is significantly lower in the cyanotic CHD group than in the acyanotic CHD group. But there are no significant differences in the other lipid profiles measurement and incidence of dyslipidemia between groups.

Cyanotic congenital heart disease: Impact on growth and endocrine functions.

Objective: To find out the impact of Cyanotic Congenital Heart Disease (CCHD) on growth and endocrine functions at a tertiary care child healthcare facility of South Punjab. Study Design: Case Control study. Setting: Department of Pediatric Cardiology and Department of Pediatric Endocrinology, Institute of Child’s Health (ICH), Multan, Pakistan. Period: December 2018 to March 2020. Material & Methods: During the study period, a total of 53 cases of Echocardiography confirmed CCHD were registered. Along with 53 cases, 50 controls during the study period were also enrolled. Height, weight, body mass index (BMI) along with hormonal and biochemical laboratory investigations were done. Results: There was no significant difference between gender and age among cases and controls (p value>0.05). Most common diagnosis of CCHD among cases, 24 (45.3%) were Tetralogy of Fallot (TOF) followed by 9 (17.0%) transposition of the great arteries (TGA) with Ventricular Septal Defect (VSD) with Pulmonary Stenosis (PS). Mean weight of CCHD cases was significantly lower in comparison to controls (21.19+6.24 kg vs. 26.48+8.1 kg, p value=0.0003). Blood glucose was significantly lower among cases in comparison to controls (77.58+14.58 mg/dl vs. 87.25+11.82 mg/dl, p value=0.0004). No significant difference was found in between cases and controls in terms of various hormone levels studied (p value>0.05) except Insulin-like Growth Factor-1 (IGF-1) levels (p value<0.0001). Conclusion: Children with cyanotic congenital heart disease seem to have negative effects on nutrition and growth. Change in pituitary-adrenal axis is suspected while pituitary-thyroid axis seemed to be working fine among CCHD cases. Serum glucose and IGF-1 levels were significantly decreased among CCHD cases.

Gastrostomy Button Placement in Infants With Cyanotic Versus Acyanotic Congenital Heart Disease

Infants with congenital heart disease (CHD) may exhibit increased metabolic demands, and many will undergo placement of a gastrostomy to achieve adequate nutritional intake. There is a paucity of data, however, comparing the operative risks and overall complications of gastrostomy placement in cyanotic versus acyanotic infants with CHD. We hypothesized that patients with cyanotic CHD would have a higher rate of gastrostomy-associated complications than infants with acyanotic CHD. We retrospectively reviewed patients who underwent gastrostomy button placement after cardiac surgery for CHD between 2013 and 2018. Patients were stratified into cyanotic CHD and acyanotic CHD cohorts. Patient data were extracted from the Society of Thoracic Surgeons database and merged with clinical data related to gastrostomy placement and complications from chart review. Unadjusted analyses were used to find covariates associated with cyanotic CHD and acyanotic CHD, using a t-test or Wilcoxon rank-sum test for continuous data, depending on normalcy, and χ2 or Fisher's exact tests for categorical data depending on the distribution. There were 257 infants with CHD who underwent gastrostomy placement during the study period, of which 86 had cyanotic CHD. There were no significant differences in baseline weight or preoperative albumin levels between the two groups. Patients with cyanotic CHD had a lower incidence of comorbid syndromes (P=0.0001), higher Society of Thoracic Surgeons-European Association for Cardio-Thoracic Surgery scores (P<0.0001), and higher postoperative mortality rate (P=0.0189). There was a higher rate of granulation tissue formation in patients with acyanotic CHD (48.5% versus 22.1%, P<0.0001). There were no differences in other gastrostomy button-related complications, including leakage, wound infection, or dislodgement. Patients with acyanotic CHD demonstrated a higher incidence of granulation tissue. We found no difference in gastrostomy-specific complication rates between the two groups, with the notable exception of granulation tissue formation. Based on this study, the diagnosis of cyanotic CHD does not increase the risk of gastrostomy-related complications.

Growth Restriction in Infants and Young Children with Congenital Heart Disease.

The purpose of this study was to determine the prevalence of growth restriction in infants and young children with congenital heart disease (CHD) and investigate the relationship between poor growth, feeding difficulties, cardiac classification, and nutrition intervention on outcomes. This is a prospective observational cohort study of infants and young children with CHD aged 0-3 years admitted to hospital for cardiac surgery. Anthropometry, growth history, cardiac classification, cardiac diagnosis, feeding difficulty, and nutrition intervention data were collected for 78 participants. Many participants demonstrated growth restriction as evidenced by a z-score ≤ -2 for population growth parameters including weight/age z-score (n = 18, 23%), height/age z-score (n = 16, 21%), and weight/height z-score (n = 12, 18%). Increased hospital length of stay was associated with factors including faltering growth preadmission (P = .009), tube feeding required preadmission (P = .002), diagnosis of cyanotic CHD (P = .015), and presence of a feeding difficulty (P = .015). Growth restriction remains an ongoing problem in children with CHD. Faltering growth preadmission and lower growth parameters were associated with an increased hospital length of stay. Nutritional screening from diagnosis may detect growth faltering, improve access to early nutrition intervention, and improve patient outcomes.

Emergency Department Management of Pediatric Patients with Cyanotic Heart Disease and Fever

BackgroundChildren with cyanotic congenital heart disease (CCHD) are living longer and presenting to the Emergency Department (ED) in larger numbers. A greater understanding of their diagnoses and appropriate management strategies can improve outcomes. ObjectiveOur objective was to describe the ED diagnoses, management, and dispositions of pediatric CCHD patients who present with fever. MethodsWe retrospectively analyzed pediatric ED patients age 18 years or younger with a previous diagnosis of CCHD who presented with a fever from January 2000 to December 2005. ResultsOf 809 total ED encounters, 248 (30.6%) were eligible for inclusion. Of those meeting inclusion criteria, 59 (23.8%) required supplemental oxygen and 67 (27%) received intravenous fluid. ED diagnoses were febrile illness in 120 (48.4%), pneumonia in 35 (14.1%), upper respiratory infection in 19 (7.7%), viral syndrome in 17 (6.9%), gastroenteritis in 17 (6.9%), otitis media in 10 (4.0%), bronchiolitis in 5 (2.0%), pharyngitis in 3 (1.2%), croup in 3 (1.2%), bronchitis in 3 (1.2%), urinary tract infection in 3 (1.2%), mononucleosis in 2 (0.8%), pericarditis in 2 (0.8%), influenza in 1 (0.4%), cellulitis in 1 (0.4%), bacteremia in 1 (0.4%), and potential endocarditis in 1 (0.4%). In terms of patient disposition, 53.2% were discharged, 44.4% were floor admissions, and 2.4% were intensive care unit admissions. ConclusionsA cardiac cause of fever in CCHD patients is rare. Because of limited cardiopulmonary reserve, they might require supplemental oxygen, intravenous fluids, and hospital admission.

The role of echocardiography in the diagnosis of cyanotic congenital heartdisease in neonate

先天性心脏病(简称先心病)是新生儿时期最常见的先天性畸形,其发病率为0.6%～0.8%,其中约30%为青紫型复杂病例,是导致新生儿心力衰竭和严重低氧血症的主要原因[1].青紫型先心病代表性类型包括完全性大动脉转位、极重型法乐四联症、三尖瓣闭锁、完全性肺静脉异位引流、肺动脉闭锁、单心室、完全性房室隔缺损、动脉单干、左心发育不良综合征等.这些心脏畸形如不经治疗,30%在生后1个月内夭折,60%在1岁以内死亡,是造成新生儿死亡的主要原因之一.近年来国内外对先心病治疗的研究已经取得了很大进展,许多复杂性心血管畸形患儿在出生后不久即可根治,手术存活率已明显提高.因此,早期正确的诊断对于指导及时有效的治疗、降低新生儿病死率具有重要价值。
