Anisocytosis as a possible predictor of low cardiac output syndrome in children undergoing mitral valve surgery. Adv Med Sci 2024; 69:147-152. [PMID: 38493878 DOI: 10.1016/j.advms.2024.03.004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/16/2023] [Revised: 12/20/2023] [Accepted: 03/15/2024] [Indexed: 03/19/2024]
Abstract
PURPOSE Mitral valve surgery in children involves correcting congenital and acquired pathologies, with a reported mortality rate of 0.9%. Low cardiac output syndrome (LCOS) is a serious complication with the incidence of 20-25%. The aim of the study was to estimate possible prognostic factors of LCOS in children undergoing mitral valve procedure. MATERIAL AND METHOD This single-center retrospective analysis enrolled children aged <18 years who underwent mitral valve surgery during 24 year period. Preoperative clinical and laboratory parameters, and operative factors were analyzed. RESULTS Thirty consecutive pediatric patients (11 (37%) males and 19 (63%) females) in median (Q1 - Q3) age of 57 (25-115) months, who underwent mitral valve replacement, were included. The 30-day mortality was 7% (2 patients) and was related to postoperative multiorgan failure. LCOS occurred in 8 (27%) children. The receiver operator curve (ROC) analysis established parameters that have predictive value for LCOS occurrence: cardiopulmonary bypass (CPB) time, with 89 min as optimal cut-off point (AUC = 0.744, p = 0.011) yielding sensitivity of 100% and specificity of 42.9%; left ventricular ejection fraction (LVEF) < 60 % (AUC = 0.824, okp = 0.001) with sensitivity of 62.5% and specificity of 93.75%; and red blood cell distribution width (RDW) above 14.5 % (AUC = 0.840, p < 0.001; sensitivity of 87.5% and specificity of 75%). CONCLUSIONS In mitral valve replacement in pediatric patients, CPBtime above 89 min, preoperative LVEF below 60% and preoperative RDW above 14.5% can be regarded as the potential predictors of LCOS.

Abstract
Congenital heart disease (CHD) is a prevalent birth defect and a significant contributor to childhood mortality. The major characteristics of CHD include cardiovascular malformations and hemodynamical disorders. However, the impact of CHD extends beyond the circulatory system. Evidence has identified dysbiosis of the gut microbiome in patients with CHD. Chronic hypoxia and inflammation associated with CHD affect the gut microbiome, leading to alterations in its number, abundance, and composition. The gut microbiome, aside from providing essential nutrients, engages in direct interactions with the host immune system and indirect interactions via metabolites. The abnormal gut microbiome or its products can translocate into the bloodstream through an impaired gut barrier, leading to an inflammatory state. Metabolites of the gut microbiome, such as short-chain fatty acids and trimethylamine N-oxide, also play important roles in the development, treatment, and prognosis of CHD. This review discusses the role of the gut microbiome in immunity, gut barrier, neurodevelopment, and perioperative period in CHD. By fostering a better understanding of the cross-talk between CHD and the gut microbiome, this review aims to contribute to improve clinical management and outcomes for CHD patients.

Risk factors and outcomes associated with acute kidney injury following extracardiac total cavopulmonary connection: a retrospective observational study. Transl Pediatr 2022; 11:848-858. [PMID: 35800273 PMCID: PMC9253948 DOI: 10.21037/tp-21-474] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/29/2021] [Accepted: 03/01/2022] [Indexed: 11/09/2022] Open
Abstract
BACKGROUND Total cavopulmonary connection (TCPC) is an important operation for the treatment of complex congenital heart disease. Epidemiology and outcomes for pediatric patients with acute kidney injury (AKI) following extracardiac TCPC have not been well documented. This study investigates the prevalence, risk factors, and outcomes of AKI in children after extracardiac TCPC surgery. METHODS We retrospectively evaluated patients (age at surgery <18 years) who underwent extracardiac TCPC surgery between January 2008 and January 2020 in the Pediatric Cardiac Surgical Center of Fuwai Hospital, Beijing, China. AKI was defined according to the pediatric-modified risk, injury, failure, loss of function, and end-stage renal disease criteria. RESULTS A total of 377 pediatric patients were included in this study; 123 patients (32.6%) had some degree of AKI. Among the patients with AKI, 101 (82.1%) were diagnosed with AKI-risk (AKI-R), while 22 (17.9%) were diagnosed with acute kidney injury/failure (AKI/F) (16 with AKI, and 6 with AKF). Preoperative estimated creatinine clearance (OR: 1.039, 95% CI: 1.024-1.055, P<0.001), neutrophil-to-lymphocyte ratio (OR: 1.208, 95% CI: 1.128-1.294, P<0.001), and renal perfusion pressure (OR: 0.962, 95% CI: 0.938-0.986, P=0.002) on postoperative day (POD) 0 were significantly associated with AKI after TCPC. Having previously undergone a bidirectional Glenn was significantly associated with the severity of postoperative AKI (OR: 0.253, 95% CI: 0.088-0.731, P=0.011). Furthermore, AKI was associated with prolonged mechanical ventilation time, prolonged intensive care unit stay, and composite adverse outcome. Compared with non-AKI patients, the 10-year survival rate of patients with severe AKI was significantly lower (95.5% vs. 65.9%, P=0.009). CONCLUSIONS Although the incidence of AKI was high in patients undergoing TCPC surgery, most cases were AKI-R. Severe AKI was significantly associated with early adverse outcomes and poor long-term survival.

Abstract
This study aimed to address the role of various inflammation-related blood indices for the assessment of in-hospital outcomes in subjects undergoing Glenn procedure. Subjects who underwent the Glenn procedure for hypoplastic left heart syndrome were analysed retrospectively. Subjects were divided into two groups: Group 1 consisted of 78 patients who were discharged, and Group 2 included 12 patients who died after surgery. Post-operative third-day neutrophil count and neutrophil-to-lymphocyte ratio value were significantly higher in the exitus group compared to the discharged group (p = 0.006 and p = 0.003, respectively). Third-day neutrophil-to-lymphocyte ratio was positively correlated with duration of intubation (r = 0.253, p = 0.018), length of stay in ICU (r = 0.296, p = 0.006) and length of hospital stay (r = 0.297, p = 0.005). Multiple logistic regression analysis revealed that patients with high third-day neutrophil-to-lymphocyte ratio (≥6) had 14.227-fold higher risk of death compared to those with lower values. In addition, higher pulmonary arterial pressure was associated with increased risk of death. Receiver operating characteristics analysis revealed that neutrophil-to-lymphocyte ratio had 66.67% sensitivity, 84% specificity, 81.61% accuracy, 40.00% positive predictive value and 94.03% negative predictive value with a cut-off point of ≥6 to predict mortality. Third-day neutrophil-to-lymphocyte ratio and increased post-operative pulmonary arterial pressure are significant predictors for in-hospital mortality in Glenn procedure recipients. A cut-off value of ≥6 for third-day neutrophil-to-lymphocyte ratio predicts mortality with 66.67% sensitivity and 84% specificity. Given its simplicity and availability, post-operative neutrophil-to-lymphocyte ratio should be monitored on a daily basis to identify patients with high risk for mortality after Glenn procedure.

Abstract
Background: Lymphocyte percentage/count, platelet-lymphocyte ratio (PLR), and neutrophil-lymphocyte ratio (NLR) have shown prognostic significance in patients with cancer, stroke, and following cardiac surgery. However, the utility of these blood parameters for assessing the 30-day postoperative risk for lumbar fusion complications has not been established. Methods: In this single-center-single-surgeon retrospective series, 77 consecutive patients underwent one- or two-level lumbar fusion. Lymphocyte percentage/count, PLR, and NLR were investigated as predictors of 30-day postoperative complications. Results: Ten of 77 patients had postoperative complications. A unit increase in NLR and lymphocyte percentage was significantly associated with a 23% increase and 7% decrease, respectively, in the odds of a complication occurring. Preoperative NLR ≥ 2.32 and lymphocyte percentage ≤ 29.5% significantly discriminated between the “complication” and “no-complication” groups. Conclusion: Patients with a preoperative lymphocyte percentage of ≤29.5% and/or NLR ≥2.32 should be closely monitored as high-risk groups susceptible to 30-day postoperative complications after lumbar fusion.

Abstract
Operative mortality after repair of congenital heart disease has improved dramatically over the past few decades. Nevertheless, there is always room for the additional mitigation of complications and mortality. Being able to anticipate adverse outcomes is clearly important, especially when using low-cost and easily accessible resources. The neutrophil-lymphocyte ratio (NLR) is defined as the ratio of the absolute neutrophil to lymphocyte count, which can be easily measured using a regular white blood cell count. Recently, preoperative NLR has been shown to be a predictor of outcomes in patients undergoing congenital heart surgery. Although it presented promising results, there are still many gaps to be filled like the normal value for children, the ideal cutoff value to predict adverse outcomes, the wide variation and its correlation with other biomarkers, and if it is a modifiable risk factor. The aim of this review is to understand the prognostic value of preoperative NLR as a biomarker predictor of outcomes in patients undergoing congenital heart surgery based on previous clinical studies and to propose future directions in order to solve the above-mentioned questions.

Abstract
INTRODUCTION The Coronavirus Disease 2019 (COVID-19) pandemic negatively impacted global healthcare. Consequences in Pediatric and Congenital Heart Surgery programmes and mortality of congenital heart patients infected with severe acute respiratory syndrome coronavirus-2 (SARS-Cov-2) is still to be determined. OBJECTIVE To study the COVID-19 pandemic implications in Brazilian Pediatric and Congenital Heart Surgery programmes. METHODS We conducted a national online survey covering all states that perform Pediatric and Congenital Heart Surgery from 10 November to 22 November, 2020, using a Google forms questionnaire. We formulated questions related to impact on surgical volume, case-mix, and mortality. Then we asked about short-term post-operative COVID-19 infection and outcomes. RESULTS We received responses from 46 centres representing all states where there were a Pediatric and Congenital Heart Surgery programme and all high-volume centres across the country. All but one centre experienced a significant decrease in surgical volume, and 23.9% of the responders revealed less than one-quarter of volume decrement. On the other hand, in over 70% of the centres, there was a significant surgical volume reduction. In addition to this, there was a shift in case-mix in 41 centres (89.1%) towards more complex cases. More than one-third of the responders revealed increased mortality in 2020 compared to previous years, and 43.5% of the programmes (20 centres) had at least one patient contaminated by SARS-Cov-2, accounting for 48 patients. Mortality in post-operative infected patients was 45.8% (22 patients). CONCLUSIONS In general, Brazilian Pediatric and Congenital Heart Surgery programmes were severely affected by decreased surgical volume, unbalanced case-mix towards more complex cases, and increased mortality. Almost half of the programmes related post-operative COVID-19 contamination with high mortality.

Abstract
Background Neutrophil–lymphocyte ratio (NLR) is a valuable indicator for evaluating inflammation and adverse outcomes after cardiac surgery. The objective of this study was to evaluate the association of perioperative NLR with clinical outcomes in infants undergoing congenital heart surgery with cardiopulmonary bypass. Methods We performed a retrospective review of 424 consecutive infants (≤ 1 year) undergoing cardiac surgery between January 2019 and September 2019. Neonates (≤ 28 days) and patients with incomplete NLR data were excluded. The study endpoint was a composite of poor outcomes after surgery. We assess the correlation between perioperative NLR and clinical outcomes. A receiver operating characteristic curve and multivariable logistic regression were applied to identify the prognosis performance of postoperative NLR for poor outcomes. Results A total of 68 (16%) infants experienced at least one of the poor outcomes. Postoperative NLR on the third day after the surgery showed the best prognostic significance (AUC = 0.763, 95%CI 0.700–0.826) among perioperative period, with a cut-off value of 2.05. Postoperative NLR was also strongly correlated with mechanical ventilation time, length of ICU and hospital stay (p < 0.001). Multivariable logistic regression revealed that elevated postoperative NLR (OR 3.722, 95%CI 1.895–7.309, p < 0.001) was an independent risk factor for poor outcomes in infants after cardiac surgery. Conclusions Postoperative NLR was correlated with increased mechanical ventilation time, length of ICU and hospital stay. Elevated postoperative NLR was an independent predictor for poor outcomes after cardiac surgery in infants.

Abstract
INTRODUCTION Elevated neutrophil-lymphocyte ratio (NLR) has been associated with poorer outcomes in cyanotic patients undergoing single ventricle palliation. Little is known about this biomarker on patients with tetralogy of Fallot (TOF), the most common cyanotic congenital heart disease. Our objective is to study the impact of preoperative NLR on outcomes of TOF patients undergoing total repair. METHODS This retrospective study included 116 consecutive patients between January 2014 and December 2018. Preoperative NLR was measured from the last complete blood count test before the surgery. Using the cutoff value of 0.80, according to the receiver-operating characteristic (ROC) curve, the sample was divided into two groups (NLR < 0.80 and ≥ 0.80). The primary endpoint was hospital length of stay (LOS). RESULTS ROC curves showed that higher preoperative NLR was associated with longer hospital LOS, with an area under the curve of 0.801±0.040 (95% confidence interval 0.722 - 0.879; P<0.001). High preoperative NLR was also associated with long intensive care unit (ICU) LOS (P=0.035). Preoperative NLR predicted longer hospital LOS with a sensitivity of 63% and a specificity of 81.4%. CONCLUSION Higher preoperative NLR was associated with long ICU and hospital LOS in patients undergoing TOF repair.

Abstract
INTRODUCTION Acute kidney injury is a risk factor for chronic kidney disease and mortality after congenital heart surgery under cardiopulmonary bypass. The neutrophil-lymphocyte ratio is an inexpensive and easy to measure biomarker for predicting outcomes in children with congenital heart disease undergoing surgical correction. OBJECTIVE To identify children at high risk of acute kidney injury after tetralogy of Fallot repair using the neutrophil-lymphocyte ratio. METHODS This single-centre retrospective analysis included consecutive patients aged < 18 years who underwent tetralogy of Fallot repair between January 2014 and December 2018. The pre-operative neutrophil-lymphocyte ratio was measured using the last pre-operative complete blood count test. We used the Acute Kidney Injury Network definition. RESULTS A total of 116 patients were included, of whom 39 (33.6%) presented with acute kidney injury: 20 (51.3%) had grade I acute kidney injury, nine had grade II acute kidney injury (23.1%), and 10 (25.6%) had grade III acute kidney injury. A high pre-operative neutrophil-lymphocyte ratio was associated with grade III acute kidney injury in the post-operative period (p = 0.04). Patients with acute kidney injury had longer mechanical ventilation time (p = 0.023), intensive care unit stay (p < 0.001), and hospital length of stay (p = 0.002). CONCLUSION Our results suggest that the pre-operative neutrophil-lymphocyte ratio can be used to identify patients at risk of developing grade III acute kidney injury after tetralogy of Fallot repair.

Abstract
Background Tetralogy of Fallot (TOF) is the most common cyanotic congenital heart disease. Absolute lymphocyte count (ALC) is a low‐cost and easy‐to‐obtain inflammatory indicator; however, its association with the prognosis of patients with TOF remains unknown. This study aimed to determine the prognostic value of preoperative ALC in children with TOF. Methods and Results This retrospective study included 707 patients aged <6 years who underwent corrective operations for TOF between January 2016 and December 2018 in Fuwai Hospital, China. The end points were mortality, extracorporeal membrane oxygenation placement, postoperative hospital stay >30 days, and severe postoperative complications; patients were grouped on the basis of prognosis: poor prognosis (n=76) and good prognosis (n=631). Univariable and multivariable logistic regression analyses were performed to identify the independent risk factors for poor prognosis, on which a risk scoring system was based. The receiver operating characteristic curve was used to assess model performance. Using another model without ALC, the effect of the addition of ALC was assessed. Results suggested that ALC was an independent factor with a cutoff point of 4.36×109/L. The addition of ALC improved the area under the curve from 0.771 to 0.781 (P<0.001). To avoid reverse causality and further control for confounding factors, the patients were further divided on the basis of ALC level, and a propensity score matching was performed; 117 paired patients were identified for further analysis. Low ALC levels had an odds ratio of 3.500 (95% CI, 1.413–8.672). Conclusions Low preoperative ALC represents an independent predictor of poor prognosis in children with TOF.

Abstract
INTRODUCTION Elevated neutrophil-lymphocyte ratio (NLR) has been associated with poorer outcomes in children undergoing congenital heart surgery under cardiopulmonary bypass (CPB). OBJECTIVE To compare preoperative NLR levels between cyanotic and acyanotic children undergoing surgical repair with CPB. METHODS We performed a retrospective cohort study in 60-paired children (30 with tetralogy of Fallot [TOF] and 30 with ventricular septal defect [VSD]) between January 2018 and December 2019 matched by age, weight, and gender. Preoperative NLR was measured from the last complete blood count test before the surgery. All of them had negative viral screening. RESULTS The median age in VSD children was 9.5 months (interquartile range [IQR]: 5-12), weight 7 kg (IQR: 5.5-8.7), 19 (63%) was female, and NLR was 0.45 (IQR: 0.3-0.65). The median age in TOF children was 8.5 months (IQR: 5-12), weight 7.6 kg (IQR: 5.8-8.7), 16 (53%) were female, and NLR was 0.67 (IQR: 0.41-1.1). Demographic parameters did not show any statistically significant difference between groups (p > .05). Children with TOF had higher preoperative NLR compared with VSD patients (p = .004). As lower O2 saturation as higher the NLR (p = .005). CONCLUSION The preoperative level of NLR was higher in cyanotic congenital heart disease patients.

Abstract
BACKGROUND We aimed to explore the relationship between the neutrophil to lymphocyte ratio (NLR) and the early clinical outcomes in children with congenital heart disease (CHD) associated with pulmonary arterial hypertension (PAH) after cardiac surgery. METHODS A retrospective observational study involving 190 children from January 2013 to August 2019 was conducted. Perioperative clinical and biochemical data were collected. RESULTS We found that pre-operative NLR was significantly correlated with AST, STB, CR and UA (P < 0.05), while post-operative NLR was significantly correlated with ALT, AST, BUN (P < 0.05). Increased post-operative neutrophil count and NLR as well as decreased lymphocyte count could be observed after cardiac surgery (P < 0.05). Level of pre-operative NLR was significantly correlated with mechanical ventilation time, ICU stay time and total length of stay (P < 0.05), while level of post-operative NLR was only significantly correlated to the first two (P < 0.05). By using ROC curve analysis, relevant areas under the curve for predicting prolonged mechanical ventilation time beyond 24 h, 48 h and 72 h by NLR were statistically significant (P < 0.05). CONCLUSION For patients with CHD-PAH, NLR was closely related to early post-operative complications and clinical outcomes, and could act as a novel marker to predict the occurrence of prolonged mechanical ventilation.

Neutrophil-to-Lymphocyte and Platelet-to-Lymphocyte Ratio in Univentricular Patients From Birth to Follow-Up After Fontan-Predicting Lymphatic Abnormalities. Front Pediatr 2021; 9:740951. [PMID: 34956972 PMCID: PMC8692875 DOI: 10.3389/fped.2021.740951] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/14/2021] [Accepted: 11/17/2021] [Indexed: 11/13/2022] Open
Abstract
Background: Reliable laboratory parameters identifying complications after Fontan surgery including the lymphatic abnormalities and the development of protein-losing enteropathy (PLE) are rare. Neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocte ratio (PLR) are inflammatory markers and have been studied to predict outcome and prognosis in various diseases. The aim of this study was to investigate NLR and PLR from birth to follow-up after Fontan and evaluate their use as prognostic parameters for single ventricle patients regarding the development of lymphatic malformations during follow-up. Materials and Methods: Sixty-six univentricular patients who underwent Fontan surgery and had 6-month follow-up magnetic resonance imaging (MRI) with T2 weighted lymphatic imaging after total cavopulmonary connection (TCPC) surgery were included in the study. NLR and PLR were determined at specific time points, from neonatal age to follow-up after Fontan operation and correlated to data from the MRI 6 months after Fontan. Results: NLR and PLR increase significantly over time from the first surgery during infancy to the follow-up after Fontan (both p < 0.0001), with a significant increase after the Glenn surgery for both ratios (each p < 0.0001). Higher NLR (p = 0.002) and higher PLR (p = 0.004) correlated with higher-grade classification of lymphatic abnormalities in T2-weighted imaging 6 months after Fontan surgery and higher NLR correlated with higher transpulmonary gradient prior to Fontan surgery (p = 0.035) Both ratios showed a significant correlation to total protein at follow-up (NLR p = 0.0038; PLR<0.0001). Conclusion: Increased NLR and PLR correlate with higher degree lymphatic malformations after TCPC and therefore might contribute as valuable additional biomarker during follow-up after TCPC. NLR and PLR are simple, inexpensive and easily available parameters to complement diagnostics after TCPC.
