Abstract MicroRNAs (miRNAs) are noncoding RNAs that play an important role in the regulation of inflammation and have not been evaluated in exhaled breath condensates (EBC) of patients with esophageal atresia and tracheoesophageal fistula (EA–TEF). It is aimed to evaluate the levels of miRNA-21 and miRNA-24 in EBC of patients with EA–TEF. Patients who received surgery for EA–TEF (EA) were assessed for age, sex, types of anomaly, surgical treatments, and respiratory problems. A 500–1000 mL of EBC was obtained from each participant with EcoScreen. The levels of miRNA-21 and miRNA-24 in the EBC were analyzed by real-time polymerase chain reaction and compared between the EA group and the control group consisting of healthy children with no history of respiratory problems (n = 17). The levels of miRNAs in relation to respiratory problems and gastroesophageal reflux (GER) were also assessed. A total of 19 patients were enrolled in the EA group with a mean age of 7.8 ± 3.2 years and a male-to-female ratio of 10:9 EA cases had significantly lower levels of miRNA-21 (P < 0.05) compared to that in control group. The miRNA-24 levels did not differ between groups (P > 0.05). EA patients with positive pH testing for GER (n = 6) and fundoplication (n = 6) had higher levels of miRNA-21 than those with normal pH testing and without fundoplication, respectively (n = 13, P < 0.05). The levels of miRNA-21 and miRNA-24 did not differ between patients with and without proton pump inhibitor treatment (P > 0.05). The lower levels of miRNA-21 in the EBC of EA patients suggest a hyperreactive airway problem, which may be associated with GER and its surgical treatment.

Abstract Aim MicroRNAs (miRNAs) are noncoding RNAs that play a role in regulation of inflammation and cancer. It has been shown that miRNA-21 and 24 are downregulated in the exhaled breath condensate (EBC) of children with chronic inflammatory lung disease and asthma. A prospective study was performed to evaluate the miRNA-21 and 24 levels in the EBC of patients with esophageal atresia and tracheoesophageal fistula (EA-TEF). Methods Patients operated for EA-TEF were evaluated for age, sex, type of anomaly, surgical treatment, and respiratory problems. 500–1000 μl of EBC was obtained from all patients with Ecoscreen. miRNA-21 and 24 levels in EBC were analyzed with ELISA. The results of the study group were compared with a control group (CG) consisting of healthy children with no history of respiratory problems and allergy (n = 17). miRNA levels were compared with respiratory problems and gastroesophageal reflux (GER). Results Nineteen patients with EA-TEF with a mean age of 7.8 ± 3.2 years were enrolled in the study. The male–female ratio was 10:9. The mean age of the CG was 9.1 ± 3.6 years (P > 0.05). Distal fistula (78.9%) was the most common type of anomaly. 76.5% of cases required esophageal dilatations for strictures and 15.8% of them had fistula recurrence. Fifteen of the cases with EA were diagnosed as hyperreactive airway disease and require medical treatment. When miRNA levels were compared with CG (median = 0.68), EA cases had significantly decreased levels of miRNA-21 (median = 0.64, P < 0.05). There was no difference between groups for miRNA-24 levels (P > 0.05). The miRNA levels were also compared in patients with EA, according to positive pH testing for GER, use of proton pump inhibitor (PPI) treatment, and need for fundoplication. Patients with GER in pH test (median = 0.66) and fundoplication (median = 0.66) had increased levels of miRNA-21 than patients without reflux (median = 0.63) and surgical treatment (median = 0.64) (P < 0.05). The levels of miRNA-21 and 24 did not show any significant difference in patients with and without PPI treatment (P > 0.05). Conclusion The decreased levels of miRNA-21 in EBC suggest a hyperreactive airway problem in EA patients. Increased miRNA levels in EBC are associated with GER and its surgical treatment.

There is limited data on the effect of the novel coronavirus disease (COVID-19) caused by severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) on pediatric rheumatology. We examined the prevalence of antibodies against SARS-CoV-2 in children with juvenile idiopathic arthritis (JIA) and a negative history of COVID-19 and the correlation of the presence of these antibodies with disease activity measured by juvenile arthritis disease activity score (JADAS). In total, 62 patients diagnosed with JIA, under treatment with various antirheumatic drugs, and 32 healthy children (control group) were included. Serum samples were analyzed for inflammatory markers and antibodies and their state evaluated with the juvenile arthritis disease activity score (JADAS). JIA patients do not have a higher seroprevalence of anti-SARS-CoV-2 antibodies than healthy subjects. We found anti-SARS-CoV-2 antibodies in JIA patients who did not have a history of COVID-19. The study showed no unequivocal correlation between the presence of SARS-CoV-2 antibodies and JIA activity; therefore, this relationship requires further observation. We also identified a possible link between patients’ humoral immune response and disease-modifying antirheumatic treatment, which will be confirmed in follow-up studies.

Background: Due to the tropism of human parvovirus B19 to erythroid progenitor cells, infection in patients with an underlying hemolytic disorder such as thalassemia, hereditary spherocytosis, sickle cell disease and Glucose-6-phosphate dehydrogenase deficiency leads to suppression of erythrocyte formation, referred to as transient aplasia crisis (TAC), which may be life-threatening. Objectives: Detection of parvovirus B19 DNA and its IgG antibodies in the serum of children with chronic hemolytic anemia and in apparently healthy children in Benha University Hospitals. Methodology: The study was conducted on 80 children. Forty of them with chronic hemolytic anemia, they were subdivided into 2 groups, Group (1a) included 20 patients without history of aplastic crisis, Group (Ib) included 20 patients with a history of aplastic crisis and 40 age and sex-matched apparently healthy children representing control (Group II). All patients were subjected to full history taking, clinical examination and laboratory investigations. Parvovirus B19 IgG was measured using anti-parvovirus B19 ELISA kits (SUNRED), and parvovirus B19 DNA was detected by using nestedpolymerase chain reaction. Results: The seroprevalence of parvovirus B19 IgG was significantly higher (P value =0.016) in Group Ia (50%) (10 out of 20) and Group Ib (45%) (9 out of 20) than the control group (Group II) (17.5%) (7 out of 40). There was a significant positive correlation between anti-parvovirus B19 IgG and age of all patients, frequency of blood transfusion. The prevalence of parvovirus B19 DNA was 10% (2 out of 20) in group Ia and 30% (6 out of 20) in group Ib and no viral DNA was detected in the controls (P value=0.001). Although 42.3% (11 out of 26) of children with β thalassemia major had a detectable level of antiparvovirus B19 virus IgG antibodies, only (23.1%) (6 out of 26) of them had B19 DNA. Anti-parvovirus B19 IgG antibodies were detected in 4 children out of 5 children of sickle cell anemia (80%) but the the prevalence of Parvovirus B19 DNA was 20% among them. Conclusion: Measures to keep away from iatrogenic and nosocomial infection transmission should be implemented including screening of donated blood for parvovirus B19 especially blood given to patients with blood disorders. Recommendation: Data from this study support the need for introduction of an approved vaccine that mainly protects children with chronic hemolytic anemia against that infection.

Abstract Objective: Ten warning signs of primary immunodeficiency (PID) were suggested by the Jeffrey Modell Foundation (JMF), to increase physician awareness of PID. These warning signs have not yet been evaluated for patients with secondary immunodeficiency (SID). This study investigated whether the 10 warning signs used for the diagnosis of PID are sufficient for the diagnosis of SID, and explored the possibility of additional signs.Methods: This prospective study was conducted between June and December 2020. The mothers of 162 patients with PID and SID, and mothers of 200 healthy children, were asked to complete a questionnaire about family and personal history in addition to the warning signs of PID developed by the JMF. A JMF score was created by giving one point for each “Yes” answer for the 10 warning signs of PID. Medical records of the patients were evaluated for possible additional warning signs for PID and SID. Results: The JMF scores of the PID (3.36 ± 1.65) and SID (3.72 ± 1.12) groups were significantly higher than the scores of the control group (0.34 ± 0.61) (p < 0.05). A sign for immunological evaluation in two patients without warning signs in the PID group was found to be chronic diarrhea. In addition to the 10 JMF warning signs, we found that consanguinity and a family history of tuberculosis were statistically significant in our PID group, compared with the SID and control groups. Conclusions: The JMF warning signs are important for early diagnosis of PID. Our study showed that these signs may also be used for the early diagnosis of SID in patients and, according to our results, in addition to the 10 JMF signs for PID, parental consanguinity, chronic diarrhea, and a family history of tuberculosis may also be considered warning signs for the early diagnosis of PID.

Abstract Background: Carbon monoxide (CO) produced during oxygen-dependent cleavage of porphyrin ring of heme is excreted in exhaled breath. The catabolism of heme is increased when red blood cells are destroyed at an accelerated rate. Thus, quantifying CO in exhaled breath could serve as an indicator of hemolysis. However, the requirement for forced breath sample has limited the measurement of exhaled CO in young children. Objective: To assess end-tidal CO concentration (ETCOc) in children with sickle cell anemia (SCA). Design/Methods: ETCOc was measured using the CoSense ETCO Monitor (Capnia Inc. Palo Alto, CA). Children between 5-14 years with SCA (Hb SS) who were not on chronic transfusions were eligible. Healthy children served as age-matched controls. Children with exposure to second-hand smoke, acute respiratory infection or symptomatic asthma were excluded. End-tidal breath samples were collected by placing the tip of a nasal cannula 5 mm into the nares. Up to 3 measurements were taken for each subject and the highest ETCOc value was used for analysis. (ClinicalTrials.gov: NCT01848691) Results: The mean (range) age of 16 children with SCA and 16 controls was 9.7 years (5-14 years) and 9.9 years (5-14 years), respectively. The mean (± s.d.) ETCOc for SCA was 4.85 ± 2.24 ppm versus 0.96 ± 0.54 ppm for control group (p<0.001). The ETCOc in the control group ranged from 0.2 to 2.3 ppm, but was ≤1.2 ppm in 14/16, which is suggested as the upper limit of normal for healthy children. In the SCA group, the ETCOc range was 1.8 to 9.7 ppm, with values ≥2.4 ppm in 15/16 subjects. A threshold ETCOc value of >2.1 ppm provided both sensitivity and specificity equal to 93.8% (69.8-99.8%) for distinguishing SCA from healthy children. Children with SCA who had higher absolute reticulocyte count also demonstrated higher ETCOc (r=0.62, p=0.011). Patients with severe anemia (hemoglobin <8 g/dL) had a higher mean ETCOc (5.43 ppm) than the rest (4.40 ppm) but the difference was not significant. ETCOc level tended to increase with age in SCA (r=0.45, p=0.08). Conclusions: Carbon monoxide in exhaled breath can be measured in young children in the clinic using a portable monitor. ETCOc may be a valuable tool for non-invasive monitoring of the severity of hemolysis in SCA. The mean ETCOc was 5-fold higher in SCA compared with controls, with little overlap seen between the groups. This suggests a potential use for ETCOc as a point-of-care screening test for SCA in children. Figure 1 Figure 1. Figure 2 Figure 2. Disclosures Lal: Capnia, Inc: Research Funding.

Abstract Objective Myocarditis is an inflammatory disease of the cardiac muscle. Prognosis is most often good but, in some patients, the disease can be fulminant. Our aim with this study was to determine interleukin-9 (IL-9) and interleukin-17 (IL-17) levels in myocarditis cases with different etiologies. Materials and methods Thirty one patients with myocarditis and 30 healthy controls of similar age and gender without a history of chronic disease were included in the study. All 31 patients were clinically myocarditis. In some of these patients, the cause of myocarditis is acute rheumatic fever or Kawasaki disease. Serum samples of the patients were taken during diagnosis in order to analyze serum IL-9 and IL-17 levels and sedimentation rate, CRP, ASO, pro-BNP, CK-MB, and Troponin-I tests were performed. Results It was found that IL-17 levels were statistically significant in all acute rheumatic fever, Myocarditis and Kawasaki patients compared to the control group (p = 0.001) and that cut-off was 4.30 pg/mL. This value was determined to be 71% sensitive and 67% specific for IL-17 (AUC = 0.761). Conclusions Both of the mean and median levels of IL-17 were significantly higher in pediatric patients with myocarditis than in healthy children. Our study made us think that complications of myocarditis and associated morbidity can be prevented by IL17 inhibitors. The high levels of IL17 found in our study may be a reference for future study.

Background. Oxidative stress plays a role in the pathogenesis of many chronic inflammatory lung diseases. Exhaled breath condensate (EBC) collection is a noninvasive method to investigate pulmonary oxidative stress biomarkers such as malondialdehyde (MDA).Subjects and Methods. We measured MDA levels in EBC in a large number of patients (N=194) with respiratory diseases: asthma (N=64), bronchiectasis (BE,N=19), chronic obstructive pulmonary disease (COPD,N=73), idiopathic pulmonary fibrosis (IPF,N=38). Fourteen healthy nonsmoking subjects were included as controls.Results. Excluding IPF subjects, MDA levels were significantly higher in all disease groups than in control group. MDA was significantly higher in COPD than asthmatic and BE subjects. Among asthmatics, corticosteroids-treated subjects had lower MDA levels than untreated subjects. COPD subjects showed an inverse correlation between MDA concentrations and FEV1% (rho: −0.24,P<.05).Conclusions. EBC-MDA is increased in subjects with chronic airway disorders, particularly in COPD, and it is related to FEV1reduction.
