Neutrophil-to-lymphocyte ratio as a predictive and prognostic marker in children with dilated cardiomyopathy

OBJECTIVES

We aimed to evaluate neutrophil-to-lymphocyte ratio in children with acute heart failure due to dilated cardiomyopathy, to assess the predictive and prognostic values of neutrophil-to-lymphocyte ratio, and to correlate its levels with brain natriuretic peptide and other various data in these patients.

METHOD

We included 50 children with acute heart failure due to dilated cardiomyopathy as the patient group. Fifty healthy children of matched age and sex served as the control group. Patients were evaluated clinically and by echocardiography. A complete blood count with differentiation to evaluate neutrophil-to-lymphocyte ratio was done, and the serum level of brain natriuretic peptide was also measured. All patients were followed up for death or readmission for a period of one year.

RESULTS

Neutrophil-to-lymphocyte ratio was significantly higher in patient group as compared to the control group. Neutrophil-to-lymphocyte ratio was significantly increased in patients with higher severity of heart failure. There was a significant increase in neutrophil-to-lymphocyte ratio in patients with bad prognoses compared to those with good prognoses. There was a significant positive correlation between neutrophil-to-lymphocyte ratio and both brain natriuretic peptide and clinical stage of heart failure while there was a significant negative correlation between neutrophil-to-lymphocyte ratio and left ventricular systolic function. The best cut-off of neutrophil-to-lymphocyte ratio to predict adverse outcomes in children with dilated cardiomyopathy was >3.6 with 87% sensitivity and 79% specificity. The cut-off of neutrophil-to-lymphocyte ratio to predict patients who will not respond to conventional treatment was ≥3.85 with 85% sensitivity and 100% specificity.

CONCLUSION

Neutrophil-to-lymphocyte ratio is a cheap good predictive and prognostic biomarker in children with dilated cardiomyopathy.

Serum-soluble suppression of tumourigenicity-2 as a biomarker in children with congestive heart failure

BACKGROUND

We aimed to evaluate serum soluble suppression of tumorigenicity-2 in children with congestive heart failure, to assess the diagnostic and prognostic values of soluble suppression of tumorigenicity-2 in these patients, and to correlate its levels with various clinical and echocardiographic data.

METHODS

We included 60 children with congestive heart failure as the patient group. Sixty healthy children of matched age and sex served as the control group. Patients were evaluated clinically and by echocardiography. Serum level of suppression of tumorigenicity-2 was measured for patients at admission. All patients were followed up for death or readmission for a period of one year.

RESULTS

Soluble suppression of tumorigenicity-2 was significantly higher in children with congestive heart failure as compared to the control group. Soluble suppression of tumorigenicity-2 was significantly increased in patients with higher severity of congestive heart failure. There was a significant increase in soluble suppression of tumorigenicity-2 in patients with bad prognosis compared to those with good prognosis. There was a significant positive correlation between soluble suppression of tumorigenicity-2 and respiratory rate, heart rate, and clinical stage of congenital heart failure, while there was a significant negative correlation between soluble suppression of tumorigenicity-2 and left ventricular systolic and diastolic function. The best cut-off of soluble suppression of tumorigenicity-2 to diagnose congestive heart failure was > 3.6 with 87% sensitivity and 79% specificity. The cut-off point of soluble suppression of tumorigenicity-2 to diagnose congestive heart failure in children was ≥ 31.56 ng/ml, with 95% sensitivity and 91.37% specificity. Moreover, the cut-off point of soluble suppression of tumorigenicity-2 to predict bad prognosis in children with congestive heart failure was ≥ 255.5 ng/ml, with 92% sensitivity and 89.0% specificity.

CONCLUSION

Soluble suppression of tumorigenicity-2 is a good diagnostic and predictive biomarker in children with congestive heart failure.

Acute lymphoblastic leukemia in children and SALL4 and BMI-1 gene expression

BACKGROUND

Sal-like protein 4 transcription factor (SALL4) and B cell-specific Moloney murine leukemia virus integration site 1 (BMI-1) gene were reported to cause treatment failure and relapse in several malignancies. We aimed to evaluate the prognostic value of SALL4 and BMI-1 in children with acute lymphoblastic leukemia (ALL).

METHODS

This prospective cohort study was carried out on 60 children with ALL as the patient group and 60 age- and sex-matched children as the control group. We evaluated the expression pattern of both SALL4 and BMI-1 genes in the peripheral blood using real-time reverse transcriptase-polymerase chain reaction in children with ALL at initial diagnosis before chemotherapy. We followed up with the patient group for 2 years for relapse or death.

RESULTS

Both SALL4 and BMI-1 were overexpressed in ALL children compared to the control group. Moreover, the expression of SALL4 and BMI-1 in patients with relapse was significantly higher than those with complete remission. The best cut-off of SALL4 and BMI-1 to predict relapse were >2.21 and 0.55 yielding sensitivity of 92.3% and 84.6%, respectively. Patients with overexpression of SALL4 and BMI-1 had significantly shorter overall and disease-free survival.

CONCLUSIONS

SALL4 and BMI-1 could be useful prognostic markers in children with ALL to predict relapse.

Lipid profile after omega-3 supplementation in neonates with intrauterine growth retardation: a randomized controlled trial

BACKGROUND

Neonates with intrauterine growth restriction (IUGR) have a high lipid profile that predisposes them to cardiovascular disease later in life. We aimed to evaluate the effect of omega 3 supplementation on serum leptin level, lipid profile, and growth in neonates with IUGR.

METHODS

This clinical trial was conducted on 70 full-term neonates with IUGR. Neonates were randomly divided into two equal groups; the treatment group: received omega 3 supplement (40 mg/kg/day) for 2 weeks after the establishment of full feeding, and the control group, who were followed up to full feeding without any supplementation. Serum leptin level, total cholesterol (TC), high-density lipoprotein (HDL), triglycerides (TG), low-density lipoprotein (LDL), and anthropometric measurement were evaluated at admission and after 2 weeks of omega 3 supplementation in both groups.

RESULTS

After treatment, HDL significantly increased, unlike TC, TG, LDL, LDL, and serum leptin levels, which significantly decreased in the treatment group compared to the control group after treatment. Interestingly, weight, length, and ponderal index greatly increased in omega 3-treated neonates compared to the control group.

CONCLUSION

Omega 3 supplementations lowered serum leptin level, TG, TC, LDL, and VLDL but increased HDL and growth in neonates with IUGR.

CLINICAL TRIAL REGISTRATION

The study was registered at clinicaltrials.gov (NCT05242107).

IMPACT

Neonates with intrauterine growth retardation (IUGR) were reported to have a high lipid profile that predisposes them to cardiovascular disease later in life. Leptin is a hormone that adjusts dietary intake and body mass and has a significant role in fetal development. Omega 3 is known to be essential for neonatal growth and brain development. We aimed to evaluate the effect of omega 3 supplementation on serum leptin level, lipid profile, and growth in neonates with IUGR. We found that omega 3 supplementations lowered serum leptin level and serum lipid profile but increased high density lipoprotein and growth in neonates with IUGR.

Citicoline in hypoxic ischemic encephalopathy in neonates: a randomized controlled trial

BACKGROUND

Hypoxic-ischemic encephalopathy (HIE) is one of the major complications that can lead to death or disability in neonates. We assessed the effect of citicoline as a neuroprotector in neonates with moderate and severe HIE.

METHODS

This clinical trial was carried on 80 neonates with moderate to severe HIE who were not candidates for therapeutic cooling. They were subdivided randomly into two groups; citicoline treatment group which included 40 neonates who received citicoline 10 mg / kg /12 h IV for 4 weeks plus other supportive measures and the control group which included 40 neonates who were managed with placebo and the same supportive measures. All patients were evaluated for duration of mechanical ventilation (MV), need for inotropes, seizures (type, frequency, and duration), and duration of NICU. Cranial ultrasounds and brain magnetic resonance image (MRI) were performed for all included neonates after 4 weeks of treatment. Follow- ups of all neonates for the neurodevelopmental outcomes were done at 3, 6, 9, and 12 months.

RESULTS

There was a significant reduction in the number of neonates having seizures after discharge in the citicoline-treated group (2 neonates) compared to the control group (11 neonates). Cranial ultrasound and MRI findings at 4 weeks were significantly better in the treatment group compared to the control group. Moreover, neurodevelopmental outcome showed significant improvement at 9 and 12 months in the citicoline treated neonates compared to the control group. There was statistically significant reduction in the duration of seizures, NICU stay, inotrope use, and MV in the treatment group compared to the control group. Citicoline was well tolerated with no remarkable side effects.

CONCLUSION

Citicoline could be a promising neuroprotector drug in neonates with HIE.

Baseline characteristics and analysis of predictors of the Outcome of septic pulmonary embolism in children: a retrospective observational study

BACKGROUND

Septic pulmonary embolism is a rare disease in children. We aimed to assess the clinical, microbiological, and radiological characteristics and outcomes of pediatric septic pulmonary embolism (SPE) and to identify any predictive factors for in-hospital mortality in patients with this unusual disease to enhance prognosis and treatment.

METHODS

A retrospective study to search the electronic medical records of children admitted to the pediatric pulmonology unit, Tanta University hospital with the diagnosis of SPE between January 2015 and June 2022.

RESULTS

Seventeen pediatric patients were identified; ten males and seven females with a mean age of 9.4 ± 5.2 years. The most common presenting complaints were fever and shortness of breath (n = 17) followed by chest pain (n = 9), pallor (n = 5), limb swelling (n = 4), and back pain (n = 1). Methicillin-resistant Staphylococcus aureus (MRSA) was the most common causative pathogen in nine patients. The most common extra-pulmonary septic foci were septic arthritis in five patients (29.4%), septic thrombophlebitis in four patients (23.5%), and infective endocarditis in two patients (11.8%). All patients exhibited wedge-shaped peripheral lesions and feeding vessel sign in CT chest, whereas bilateral diffuse lesions, nodular lesions, and cavitation were present in 94.1% of patients, pleural effusion was identified in 58.8% of patients, and pneumothorax was detected in 41.2% of patients. Fifteen patients improved and survived (88.2%), while two patients died (11.8%).

CONCLUSION

Early diagnosis of SPE with vigorous early therapy is critical for a better outcome, including appropriate antibiotics and timely surgical interference to eradicate extra-pulmonary septic foci.

lncRNA GAS5 and RUNX1 Genes in Children With Primary Immune Thrombocytopenia

We aimed to evaluate the expression levels and the prognostic value of growth arrest specific 5 (GAS5) and runt-related transcription factor 1 (RUNX1) genes in children with ITP. This prospective cohort study included 100 patients with newly diagnosed ITP (patient group) and 100 healthy children of matched age and sex (control group). We evaluated the expression levels of both GAS5 and RUNX1 genes at the time of diagnosis before the introduction of treatment. GAS5 was under-expressed, while RUNX1 was over-expressed among the newly diagnosed ITP children compared with the control group. Patients with GAS5 levels >0.50 had a significantly faster recovery compared with patients with levels≤0.50 while patients with levels of RUNX1≤2.6 had a significantly faster recovery compared with patients with levels >2.6. The best cut-off values of GAS5 and RUNX1 to predict complete recovery of ITP were ˃0.40 and ˂3.18, respectively, yielding a sensitivity of 76.47% and 79.41%, respectively. The best cut-off values of GAS5 and RUNX1 expression that predict chronic ITP were ˂0.17 and ˃4.1, respectively, yielding sensitivity of 88.89% and 77.78%, respectively. GAS5 and RUNX1 could be useful markers in children with primary ITP to predict disease course.

Predictive Value of Plasma Copeptin Level in Children with Acute Heart Failure

We investigated the ability of copeptin level to predict adverse outcome in pediatric heart failure (HF) and correlated copeptin level with various clinical and echocardiographic data. This cohort study was carried out on forty children with clinical picture of acute HF as the patient group and forty healthy children of matched age and sex as the control group. Echocardiographic examination and plasma copeptin level were performed for all included children at admission. Patients were followed up for 6 months for mortality or readmission. Plasma copeptin level was significantly higher in the patient group (16.2 ± 5) pmol/L compared to the control group (4.1 ± 2.3) pmol/L, P ˂0.001. Moreover, copeptin level was positively correlated with Ross classification, being the highest in patients with class IV (19.6 ± 3.9) pmol/L compared to those with class III (15.2 ± 4) pmol/L and class II (10.4 ± 1.5) pmol/L. Copeptin levels were significantly higher in patients with bad prognosis (21.2 ± 4.1) pmol/L compared to those with good prognosis (14.5 ± 4.1) pmol/L, P ˂0.001. Copeptin level had a significant positive correlation with age, heart rate, respiratory rate, and ROSS classification. On the contrary, copeptin level had a significant negative correlation with left ventricular fraction shortening and diastolic function. Copeptin at cut-off value of ≥ 19.5 pmol/L yielded a sensitivity of 75% and a specificity of 93% to predict adverse outcome in children with HF. Plasma copeptin level has a good prognostic value to predict adverse outcome in pediatric heart failure. Moreover, copeptin correlate well with the severity of pediatric HF.

Study of Serum Ferritin, Zinc, and Copper Levels in Children With Helicobacter pylori Gastritis and the Effect of the Treatment

OBJECTIVES

This study aimed to assess serum iron, zinc, and copper in symptomatic children with Helicobacter pylori infection, to correlate their serum levels with the degree of gastritis, and to evaluate the effect of H. pylori treatment on their levels.

METHODS

This study was carried out on 70 children with upper gastrointestinal tract symptoms. H. pylori infection was diagnosed by the H. pylori antigen test in the stool and histopathologic findings during upper gastrointestinal endoscopy. Patients were divided into 2 groups; H. pylori -positive and H. pylori -negative groups. Hemoglobin, serum ferritin, transferrin (sTfR), zinc, and copper were assessed in all included children.

RESULTS

The hemoglobin level, serum ferritin, and zinc were significantly lower in H. pylori -positive patients compared to H. pylori -negative patients. However, the serum copper level was comparable between the 2 groups. After treatment, the hemoglobin level, serum ferritin, and serum zinc significantly increased in H. pylori -positive patients, especially in those who responded to treatment compared to their levels before treatment. There was a significant negative correlation between the severity of histopathologic abnormalities and hemoglobin level, serum ferritin, and zinc levels, but a significant positive relation with sTfR concentrations in H. pylori -positive patients.

CONCLUSIONS

H. pylori -infected children had low serum ferritin and zinc levels but high sTfR level with no effect on serum copper levels. After treatment, hemoglobin, serum ferritin, and zinc levels significantly improved in H. pylori -positive patients. Gastric histologic findings correlated significantly with hemoglobin, serum ferritin, zinc, and sTfR levels.

Urinary C-peptide and urinary C-peptide creatinine ratio as markers for insulin resistance in obese children and adolescents

BACKGROUND

Obesity is associated with insulin resistance (IR). Identifying high-risk obese children affected with IR is crucial to apply preventive management. We aimed to assess the diagnostic value of urinary C-peptide (UCP) and urinary C-peptide creatinine ratio (UCPCR) to diagnose IR in obese children.

METHODS

This prospective cross-sectional study was performed on 60 children with obesity as the study group. Sixty healthy children of matched age and sex with normal body mass index (BMI) served as the control group. Hemostasis model for the assessment of IR (HOMA-IR), glycated hemoglobin (HbA1c), fasting blood glucose and insulin, UCP, and UCPCR were assessed in all included children.

RESULTS

UCP and UCPCR were significantly higher in children with obesity (2.075 ± 0.783) ng/ml, (0.200 ± 0.021) nmol/mmol compared to the control group (1.012 ± 0.465) ng/ml, (0.148 ± 0.016) nmol/mmol, respectively. Both UCP and UCPCR were positively correlated with each other and with HOMA-IR, HbA1c, acanthosis nigricans, waist circumference, and BMI. At cutoff ≥2.45, the sensitivity of UCP to diagnose IR in obese children was 71.4%. At cutoff ≥0.20, the sensitivity of UCPCR to diagnose IR in obese children was 87.6%.

CONCLUSIONS

UCP and UCPCR are promising surrogate markers of IR in children and adolescents with obesity. However, UCPCR is a better marker than UCP.

IMPACT

Obesity is associated with IR. Identifying high-risk obese children affected with IR is crucial to apply preventive management. We aimed to assess the diagnostic value of UCP and UCPCR to detect IR in obese children. To the best of our knowledge, we are the first to use UCP and UCPCR to assess IR in obese children. We found that UCP and UCPCR are practical, easy, dependable noninvasive markers to assess IR in children with obesity and could potentially be useful in epidemiological studies and clinical practice.

Platelet Activation Markers in Children with Pulmonary Arterial Hypertension Associated with Congenital Heart Disease

The study aimed to evaluate mean platelet volume (MPV), platelet distribution width (PDW), and platecrit in children with pulmonary arterial hypertension associated with congenital heart disease (PAH-CHD), to assess the predictive value of these platelet activation markers for adverse outcomes, and to correlate their levels with various data in these patients. This prospective cohort study included 60 children with PAH-CHD as group I and 60 children with CHD and no PAH as group II. Another 60 healthy children of matched age and sex served as the control group. All included children were evaluated by echocardiography. MPV, PDW, and platecrit were also measured using an automated blood counter. All patients were followed up for death or readmission for 6 months. MPV, PDW, and platecrit were significantly higher in group I compared to group II and the control group and they correlated well with increasing severity of PAH. MPV, PDW, and platecrit positively correlated with right ventricular diameter and mean pulmonary artery pressure, however they correlated negatively with right ventricular systolic and diastolic function. The best cut-off of platelet activation markers levels to predict poor prognosis in group I was > 11.2 FL with 75% sensitivity and 96.6% specificity for MPV, > 12.7 FL with 75% sensitivity and 61.5% specificity for PDW, and > 0.505% with 75% sensitivity and 93.2% specificity for platecrit. MPV, PDW, and platecrit were elevated in children with PAH-CHD and found to be good predictive markers for poor prognosis in these children.

Effects of adherence to the Mediterranean diet in children and adolescents with irritable bowel syndrome

BACKGROUND

Irritable bowel syndrome (IBS) is a highly prevalent gastrointestinal disorder in children and adults, which increased over the past twenty years. The Mediterranean diet is a well-known diet full of antioxidants and anti-inflammatory ingredients.

AIM

To evaluate the safety, tolerability, and effects of adherence to the Mediterranean diet on disease patterns in children and adolescents with IBS.

METHODS

This prospective, cross-sectional case-controlled study included 100 consecutive IBS patients diagnosed according to Rome IV criteria, aged 12-18 years. Patients were subdivided into two groups (50 patients each); Group I received a Mediterranean diet, and Group II on their regular diet for six months. Besides IBS scores (IBS-SSS, IBS-QoL, and total score), different clinical and laboratory parameters were evaluated at the start and end of the study.

RESULTS

The Mediterranean diet was safe and well-tolerated in IBS patients. IBS children and adolescents with good adherence to the Mediterranean diet (KIDMED Score ≥ 8 points); group I showed significant improvement in IBS scores. IBS-SSS in the Mediterranean diet group was 237.2 ± 65 at the beginning of the study and decreased to 163.2 ± 33.8 at the end of the study (P < 0.001). It did not show a significant improvement in the group with a regular diet (248.3 ± 71.1 at the beginning of the study compared to 228.5 ± 54.3 at the study end with P < 0.05). The mean IBS-SSS in the Mediterranean diet group significantly improved compared with the group with a regular diet. Mean IBS-QoL in group I improved from 57.3 ± 12.9 at the start of the study to 72.4 ± 11.2 at the study end (P < 0.001) and significantly improved when compared to its level in group II at the study end (59.2 ± 12.7 with P < 0.001), while group II showed no significant improvement in IBS-QoL at the study end when compared to the beginning of the study (59.2 ± 11.7 with P >0.05). The mean total IBS score in group I became 28.8 ± 11.2 at the end of our study compared to 24.1 ± 10.4 at the start (P < 0.05) and significantly improved when compared to its level in group II at the end of the study (22.1 ± 12.5 with P < 0.05), while in group II, non-significant improvement in the total score at the end of our study compared to its mean level at the start of the study (22.8 ± 13.5 with P > 0.05).

CONCLUSION

The Mediterranean diet was safe and associated with significant improvement in IBS scores in children and adolescent patients with IBS.

Omega 3 fatty acids can reduce early doxorubicin-induced cardiotoxicity in children with acute lymphoblastic leukemia

OBJECTIVES

Omega 3 polyunsaturated fatty acids are dietary factors with several beneficial cardiovascular effects. This study aimed to assess the possible protective effect of omega 3 fatty acids on early doxorubicin-induced cardiac toxicity in children with acute lymphoblastic leukemia (ALL).

PATIENTS AND METHODS

Sixty children of newly diagnosed ALL were randomized into two groups: group I (n = 30) who received omega 3 fatty acids 1000 mg/day for 6 months in addition to their usual protocol of chemotherapy including doxorubicin; and group II (n = 30) who received their usual doxorubicin protocol during the period from February 2020 till August 2021. Echocardiographic examinations were performed before and after the treatment. Glutathione, malondialdehyde (MDA), superoxide dismutase (SOD), troponin I, creatine kinase MB (CK-MB), and N-terminal pro-brain natriuretic peptide (NT-proBNP) were measured also before and after omega 3 treatment.

RESULTS

After 6 months of omega 3 administration, group I had a significantly lower MDA level and a significantly higher glutathione and SOD levels than group II. Similarly, the levels of troponin I, CK-MB, and NT-proBNP were significantly high in group II, whereas they were unchanged in group I after treatment. Similarly, systolic function (presented with peak mitral annular systolic velocity and two-dimensional global longitudinal strain) of the heart was preserved in omega 3-treated patients, unlike the control group that showed significant impairment of left ventricular function after 6 months.

CONCLUSION

Omega 3 fatty acids may decrease early cardiac injury and doxorubicin-induced cardiotoxicity in children with ALL.

Insulin resistance, leptin and adiponectin in lean and hypothyroid children and adolescents with obesity

BACKGROUND

Obesity usually complicates hypothyroidism. Adipokines like leptin and adiponectin secreted by adipose tissue modulate insulin resistance (IR), appetite, and obesity. The association between adipokines, IR, and thyroid hormone has not been sufficiently studied in children. We investigated leptin and adiponectin as well as IR and their association with thyroid hormone in both lean and hypothyroid children and adolescents with obesity.

METHODS

The study included 30 lean hypothyroid, 30 hypothyroid children and adolescents with obesity, and 30 healthy lean children as the control group. Serum thyroid-stimulating hormone (TSH), free triiodothyronine (fT3), free thyroxine (fT4), fasting blood glucose, fasting insulin, homeostatic model assessment method of insulin resistance (HOMA-IR), leptin, and adiponectin levels were estimated in all participants.

RESULTS

Fasting insulin, HOMA-IR, and leptin levels were significantly elevated in hypothyroid children compared to the control group; more in hypothyroid children with obesity. In contrast, adiponectin levels were significantly lower in the hypothyroid children with obesity compared to the lean hypothyroid children and controls. HOMA-IR was positively correlated to TSH and BMI but inversely correlated with fT3 and fT4 in hypothyroid children. There was no correlation between IR and either leptin or adiponectin levels. Leptin and adiponectin levels correlated well with BMI in hypothyroid children and adolescents with obesity.

CONCLUSION

Insulin resistance and leptin levels are increased in hypothyroid children and adolescents; more in those with obesity. IR is not related to leptin and adiponectin levels, however, leptin and adiponectin levels correlate well with BMI in hypothyroid children and adolescents with obesity.

IMPACT

Insulin resistance (IR) and leptin levels increase in hypothyroid children and adolescent; more with obesity. IR is not related to leptin and adiponectin levels, however leptin and adiponectin levels correlated well with BMI in hypothyroid children and adolescents with obesity.

BAFF rs9514828 gene polymorphism and the risk of the development of inhibitors in children with severe haemophilia A

INTRODUCTION

Haemophilia A (HA) is an x-linked recessive disease due to deficiency of coagulation factor VIII (FVIII). The development of neutralizing antibodies (inhibitors) against infused FVIII is a major concern. B cell activating factor (BAFF) has been implicated in several autoimmune diseases.

AIM

We aimed to evaluate the possible association of BAFF rs9514828 gene polymorphism and the risk of the development of FVIII inhibitor in children with severe HA.

METHODS

This cohort study was carried out on 100 newly diagnosed boys with severe HA who were never treated before with FVIII concentrate. Assessment of serum levels of BAFF and BAFF rs9514828 genotyping at first diagnosis was performed and the patients were followed up for the completion of a total of 50 exposure days or the development of inhibitors whichever occurred first. The patients were divided as positive or negative according to the presence or absence of inhibitors.

RESULTS

The risk allele for BAFF rs9514828 (T) was significantly more frequent in the inhibitor positive patients than the inhibitor negative patients (P = .003). In addition, CT+TT genotypes were associated with increased risk of FVIII inhibitor development. Receiver operating characteristics (ROC) analysis showed that BAFF levels could predict the development of FVIII inhibitors at a cut-off value of ≥ .92 with a sensitivity of 85.9% and a specificity of 80.2%.

CONCLUSION

BAFF rs9514828 gene polymorphism could be independent risk factor and elevated BAFF levels might be useful prognostic marker for the development of FVIII inhibitor in newly diagnosed children with severe HA.

Ocular Manifestations in Patients with Coronavirus Disease 2019 (COVID-19): A Real World Multicenter Observational Study in Egypt

Background:

The aim of the work was to evaluate the ocular manifestations in the patients with COVID-19 and its role in the prediction of the course and the outcome of the disease.

Methods:

This retrospective study was conducted at two tertiary referral COVID-19 isolation hospitals in two major university hospitals in Egypt. Two hundred and twenty-eight patients were enrolled in the study. The medical records of patients who had clinically confirmed COVID-19 between 1/5/2020 to 15/7/2020 were retrospectively reviewed. Data were collected from patient charts, including age, sex, accommodation, ocular manifestations, fever, headache, cough, dyspnea, anosmia, cyanosis, abdominal pain, anorexia, liver, kidney, cardiac manifestations, CT, X-ray finding, blood tests, and outcome of the disease.

Results:

Thirty-four patients with ocular manifestation were finally enrolled in the study with a mean age of 42.1 years; 20 patients (58.8%) were men. The incidence of ocular manifestation was 14.9% (34/228). All patients with ocular manifestations had conjunctivitis (redness, epiphora, foreign body sensation), which had been treated and resolved completely within 10 days in all patients without any permanent ocular damage. There was a trend between the presence of ocular manifestations and the associated milder disease course, although this trend was not statistically significant.

Conclusion:

Ophthalmic manifestation is common in patients with COVID-19 and it occurs more frequently in patients with mild to moderate form of COVID-19, but it could not predict the patient’s mortality.

Vitamin D and nonalcoholic fatty liver disease in children: a randomized controlled clinical trial

Vitamin D is reported to have anti-inflammatory and insulin-sensitizing effects, yet vitamin D effects on hepatic fat content in children with nonalcoholic fatty liver disease (NAFLD) are not studied sufficiently. We aimed to evaluate the role of vitamin D supplementation on the hepatic fat content and NAFLD progression in children. This randomized controlled clinical trial was performed on 109 children with biopsy-proven NAFLD; only 100 patients completed the study. Patients were randomly assigned into two groups: the treatment group who received 2000 IU/day vitamin D for 6 months and the control group who received a placebo. Anthropometric measurements, vitamin D levels, aspartate aminotransferase (AST), alanine aminotransferase (ALT), total cholesterol (TC), serum triglyceride (TG), low-density lipoprotein (LDL), high-density lipoprotein (HDL), fasting blood glucose (FBG), fasting blood insulin level (FBI), homeostasis model assessment of insulin resistance (HOMA-IR), and serum calcium level were measured at the beginning and the end of the study. Liver biopsy was taken before and at the end of the study for all included children. There was a significant improvement of the hepatic steatosis and lobular inflammation by liver biopsy in the treatment group after treatment. However, there was no significant effect on the hepatocyte ballooning or hepatic fibrosis. There were significant decrease of AST, ALT, TG, LDL, FBG, FBI, and HOMA-IR and significant increase of vitamin D levels and HDL in the treatment group compared to the placebo group (P < 0.05).Conclusion: Vitamin D supplementation was found to be beneficial in the treatment of NAFLD in children.Trial registration: www.pactr.org , PACTR201710002634203. What is Known: • Nonalcoholic fatty liver disease (NAFLD) is one of the most common causes of chronic liver disease in pediatrics. • Several studies reported a negative association between low serum vitamin D level and grades of NAFLD. What is New: • Vitamin D supplementation has significantly decreased hepatic steatosis and lobular inflammation and improved the grades of NAFLD in children, confirmed by liver biopsy, but no effect on hepatocyte ballooning or fibrosis was observed. • Adjuvant vitamin D supplementation is recommended in children with NAFLD.

Lactoferrin for iron-deficiency anemia in children with inflammatory bowel disease: a clinical trial

BACKGROUND

Iron-deficiency anemia (IDA) is common in children with inflammatory bowel disease (IBD); however, oral iron supplements are commonly associated with poor compliance due to gastrointestinal side effects. We compared the effect of lactoferrin versus oral ferrous sulfate for the treatment of IDA in children with IBD.

METHODS

Ninety-two IBD children with IDA were included but only 80 children completed the study and they were randomized into two groups: ferrous sulfate group (n = 40) who received ferrous sulfate 6 mg/kg/day for 3 months and lactoferrin group (n = 40) who received lactoferrin 100 mg/day for 3 months. Complete blood count, serum iron, total iron-binding capacity (TIBC), transferrin saturation (TS), serum ferritin, interleukin-6 (IL-6), and hepcidin 25 were measured before and after the treatment.

RESULTS

Hemoglobin (Hb), mean corpuscular volume, serum iron, TS, and serum ferritin significantly increased, while TIBC decreased significantly after the administration of either ferrous sulfate or lactoferrin compared to their baseline data. In addition, lactoferrin significantly increased Hb, serum iron, TS, and serum ferritin compared to ferrous sulfate. Moreover, lactoferrin significantly decreased IL-6 and hepcidin levels.

CONCLUSION

Lactoferrin is a promising effective treatment with fewer side effects than oral elemental iron in children with IBD and IDA.

CLINICAL TRIAL REGISTRATION

The study was registered at www.pactr.org (PACTR202002763901803).

IMPACT

Iron-deficiency anemia (IDA) in children with inflammatory bowel disease (IBD) is treated with oral iron therapy; however, oral iron supplements are commonly associated with poor compliance due to gastrointestinal side effects. To the best of our knowledge, our study was the first in pediatrics that compared the effect of lactoferrin versus oral ferrous sulfate as an iron supplement for the treatment of IDA in children with IBD. We found that lactoferrin is a promising effective treatment with fewer side effects than oral elemental iron in children with IBD and IDA.

Vitamin D in Children With Inflammatory Bowel Disease: A Randomized Controlled Clinical Trial

BACKGROUND

Vitamin D has anti-inflammatory and immune regulatory functions.

GOALS

The authors investigated the effect of vitamin D supplementation in children with inflammatory bowel disease (IBD) and hypovitaminosis D on disease activity, quality of life (QOL), inflammatory markers, and cytokines.

STUDY

This randomized double-blinded controlled clinical trial included 120 children with IBD and hypovitaminosis D; 22 of them were excluded later. Patients were randomized to receive either oral vitamin D3 in a dose of 2000 IU/day or placebo for 6 months. The primary outcome was to evaluate the effect of vitamin D supplementation on the IBD activity score. The secondary outcomes were to assess the QOL, inflammatory markers, cytokines, the safety of vitamin D, and to correlate serum vitamin D level with various clinical and laboratory variables.

RESULTS

Vitamin D supplementation significantly decreased the IBD activity score in the vitamin D group compared with the placebo group. Moreover, QOL significantly improved after vitamin D supplementation. Inflammatory markers, for example, erythrocyte sedimentation rate, C-reactive protein, and fecal calprotectin and interleukin-2 IL-12, IL-17, IL-23, and tumor necrosis factor-alpha significantly decreased in the vitamin D group. However, IL-10 significantly increased after vitamin D supplementation. Vitamin D was significantly inversely correlated with the activity score, QOL score, levels of all inflammatory markers, the frequency of hospitalization, and emergency department visits.

CONCLUSION

Vitamin D supplementation may have a beneficial effect in children with IBD.

Plasma copeptin levels in children with pulmonary arterial hypertension associated with congenital heart disease

The study aimed to evaluate the plasma copeptin levels in children with pulmonary arterial hypertension associated with congenital heart disease (PAH-CHD), to assess the predictive value of plasma copeptin level for adverse outcomes, and to correlate its levels with various data in these patients. We included 25 children with PAH-CHD as group I and 25 children with CHD and no PAH as group II. Twenty-five healthy children of matched age and sex served as the control group. Patients were evaluated by echocardiography and right heart catheterization. The plasma level of copeptin was also measured. All patients were followed up for death or readmission for 1 year. Plasma copeptin levels were significantly higher in group I compared to group II and the control group and were correlated with increasing severity of PAH. The best cutoff of plasma copeptin level to predict poor prognosis in group I was ≥24.2 ng/ml with a sensitivity of 90% and a specificity of 80%. There was a statistically significant positive correlation between plasma copeptin levels and mean pulmonary pressure, pulmonary vascular resistance, and pulmonary blood flow, while there was a statistically significant negative correlation between plasma copeptin levels and right ventricular diastolic function.Conclusion: Plasma copeptin levels are elevated in children with PAH-CHD and found to be a good predictive marker for the severity of PAH and poor prognosis in these children. What is Known: •PH is a life-threatening condition that can lead to right ventricular failure and death. •We need a non-invasive easy biomarker that can identify PH children with unfavorable prognosis who needed further intervention. What is New: •It is the first study that assessed the prognostic value of plasma copeptin levels in children with PAH-CHD. •We found that copeptin is an accurate dependable biomarker for predicting poor outcomes in children with PAH-CHD who needed extensive further intervention.

Cardiac changes in infants of diabetic mothers

Diabetes mellitus (DM) is a systemic chronic metabolic disorder characterized by increased insulin resistance and/or β- cell defects. It affects all ages from the foetal life, neonates, childhood to late adulthood. Gestational diabetes is a critical risk factor for congenital heart diseases (CHDs). Moreover, the risk increases with low maternal education, high body mass index at conception, undiagnosed pre-gestational diabetes, inadequate antenatal care, improper diabetes control, and maternal smoking during pregnancy. Maternal DM significantly affects the foetal heart and foetal–placental circulation in both structure and function. Cardiac defects, myocardial hypertrophy are three times more prevalent in infants of diabetic mothers (IDMs). Antenatal evaluation of the cardiac function and structures can be performed with foetal electrocardiography and echocardiography. Postnatal cardiac evaluation can be performed with natal and postnatal electrocardiography and echocardiography, detection of early atherosclerotic changes by measuring aortic intima-media thickness, and retinal vascular changes by retinal photography. Ameliorating the effects of diabetes during pregnancy on the offspring depends mainly on pregestational and gestational diabetes prevention. However, other measures to reduce the risk, such as using medications, nutritional supplements, or probiotics, still need more research. This review discusses the mechanism of foetal sequels and the risk factors that increase the prevalence of CHDs in gestational DM, the various cardiac outcomes of gestational DM on the foetus and offspring, cardiac evaluation of foetuses and IDMs, and how to alleviate the consequences of gestational DM on the offspring.

Comparative study of the efficacy of captopril, simvastatin, and L-carnitine as cardioprotective drugs in children with type 1 diabetes mellitus: a randomised controlled trial

OBJECTIVES

To assess the efficacy and safety of captopril, simvastatin, and L-carnitine as cardioprotective drugs in children with type 1 diabetes mellitus on different echocardiographic parameters, electrocardiographic parameter, lipid profile, and carotid intima-media thickness.

METHODS

This randomised controlled trial was conducted on 100 children with type 1 diabetes mellitus for more than 3 years during the period from September 2018 to June 2020. Fifty healthy children of matched age and sex served as a control group. The patients were randomly assigned into four groups (25 children each): no-treatment group who received no cardioprotective drug, simvastatin group who received simvastatin (10-20 mg/day), captopril group who received captopril (0.2 mg/kg/day), and L-carnitine group who received L-carnitine (50 mg/kg/day) for 4 months. Lipid profile, serum troponin I, carotid intima-media thickness, and echocardiographic examinations were performed on all included children before and after the treatment.

RESULTS

Total cholesterol and low-density lipoprotein were significantly decreased in children who received simvastatin or L-carnitine. Triglycerides significantly decreased only in children who received simvastatin. High-density lipoprotein significantly increased in simvastatin and L-carnitine groups only. Serum troponin I decreased significantly in all the three treatment groups. Carotid intima-media thickness showed no significant change in all treatment groups. Echocardiographic parameters significantly improved in simvastatin, L-carnitine, and captopril groups.

CONCLUSION

Captopril, simvastatin, and L-carnitine have a significant beneficial effect on cardiac functions in children with type 1 diabetes mellitus. However, only simvastatin and L-carnitine have a beneficial effect on the lipid profile. The drugs were safe and well tolerated.Clinical trial registration: The clinical trial was registered at www.clinicaltrial.gov (NCT03660293).
