BACKGROUND: Asthma is a chronic airway disease which is characterized by oxidant antioxidant imbalance with the generation of oxidative stress related mediators.AIM: The study aimed to evaluate the role of asymmetric dimethylarginine, and malondialdehyde as oxidant markers and serum paraoxonase activity as an antioxidant marker in asthma, and to determine their relationship to the asthma severity and lung function among asthmatic children in Egypt.PATIENTS AND METHODS: This case control study was conducted on sixty patients with asthma compared with sixty apparently healthy children of matched age and sex.RESULTS: Serum concentrations of oxidant markers as asymmetric dimethylarginine and malondialdehyde were significantly increased in asthmatic patients while anti-oxidant marker as paraoxonase activity was significantly decreased compared to healthy controls (P < 0.05). ANOVA test revealed highly significant elevation of the serum concentrations of oxidant markers while anti-oxidant marker was significantly decreased in severe asthmatic patients (P < 0.001) compared to the patients with moderate and mild asthma respectively. Serum malondialdehyde concentration was a strong predictor of asthma severity by multiple regression analysis (P < 0.05).CONCLUSION: The study revealed an imbalance between oxidative and antioxidant defence systems in asthmatic children. Serum concentration of malondialdehyde was the most predictive biomarker having a significant association with asthma severity.

Background: Asthma severity differs according to gender; in adult women, there is higher prevalence and severity of asthma than in men, and it coincides with changes in sex hormones. Recently, a new phonotype of asthma has been identified that appears after menopause, and it may be associated with decreased estrogen levels. Our goal was to study the 17β-estradiol (E2) concentrations in the blood and airways of women affected by asthma onset after menopause, evaluating its possible role in the severity of the disease. Methods: We enrolled 33 consecutive women with a diagnosis of postmenopausal asthma, recruited from the outpatient pulmonary clinic: 18 with severe (SA) and 15 with mild-to-moderate (MMA) asthma. We also included 30 age-matched healthy menopausal women as controls (HS). All subjects enrolled underwent blood and sputum collection (IS), and E2 concentrations were determined in plasma and sputum supernatant samples using an enzyme-linked immunosorbent assay (ELISA) kit. Results: Significantly higher serum concentrations of E2 were found in postmenopausal SA compared to MMA and HS, respectively (33 ± 5.5 vs. 24 ± 6.63 vs. 7.79 ± 1.54 pg/mL, p < 0.05). Similar results were found in the IS: significantly higher levels of E2 were detected in patients with postmenopausal SA compared with MMA and HS, respectively (0.34 ± 0.17 vs. 0.26 ± 0.13 vs. 0.07 ± 0.06 pg/mL, p < 0.05). We found positive correlations between IS E2 concentrations and sputum neutrophil levels in SA group (ρ = 0.52, p < 0.05). Conclusions: Our findings showed the possibility to measure E2 in the airways, and it has increased in postmenopausal asthmatic patients, especially in those with SA. Airways E2 levels may serve as a suitable biomarker of postmenopausal SA to help to phenotype SA patients with neutrophil inflammation.

BACKGROUND: Asthma is considered a chronic health illness that not only resulted in physical symptoms but also emotional effects. It is; therefore, so important to assess the quality of life of asthmatic patients besides their level of disease control. AIM: To determine the correlation of asthma control with the health-related quality of life (HRQOL) of asthmatic children in Egypt. METHODS: One hundred and twenty-eight asthmatic Egyptian children were enrolled in the study. They were subjected to asthma severity grading, asthma control questionnaire (ACQ) and pediatric asthma quality of life questionnaire (PAQLQ). Studied cases were taken from 6 primary and preparatory schools, Giza governorate. RESULTS: The mean child control score was significantly higher in not well-controlled asthmatics compared to well-controlled asthmatics (p < 0.005). The not well controlled asthmatic children showed significantly lower activity limitation score, symptoms score, and overall asthmatic score compared to controlled asthmatic children (p < 0.05). The severity of asthma shows significant positive correlation with symptoms score, emotional function score and overall asthmatic score (p < 0.05). CONCLUSION: The quality of life for the asthmatic children is strongly correlated with the level of asthma control and severity.

Background: Human toxocariasis is caused by Toxocara canis and T. cati, the nematodes in the intestine of dogs and cats, respectively. Since the association between asthma and toxocariasis is controversial, the aim of the present study was to investigate the seroprevalence of Toxocara infection among asthmatic children in comparison with healthy children. Methods: This case-control study was conducted on 92 asthmatic and 91 healthy children aged 1-16 years old in Shiraz City, Southern Iran in 2019-2020. The serum samples were tested for IgG anti-Toxocara antibodies by ELISA method using the T. canis larval excretory-secretory (E/S) antigens. The collected data were analyzed using SPSS software. Results: The seroprevalence of toxocariasis in asthmatic patients was higher than the healthy children with no significant difference in Toxocara seropositivity between two groups (9.8% vs 8.8%, P = 0.817). The association between Toxocara infection and variables such as gender and age were not statistically significant. Conclusion: There was no significant association between toxocariasis and childhood asthma. Further study on different regions such as urban and rural areas with a large sample size and using questionnaire for considering risk factors of asthma and toxocariasis is recommended.

Abstract Aim of work This is a cross sectional case control study to asses vocal folds abnormalities and voice analysis in asthmatic children to detect subclinical changes and to correlate them with their various clinical and functional grading and level of control. Methods the study included 48 asthmatic children (34 males and 14 females ) regularly attending Pediatric chest Clinic, Ain Shams university for follow up.Their median age was 7.8 years ± 2.15 IQR. A 12 age and sex matched healthy children were chosen as control group. For all patients and control the following were done: history taking,General and chest examination, Spirometry Pulmonary functions(FEV1,FVC,), videolaryngoscopy (VLS)and Multidimensional voice analysis (MDVA) . Results VideoLaryngoscopy (VLS) of asthmatic patients showed different abnormalities in 26 cases ( 54.2% ).eg Phonatory west 1mm from the middle line(4 cases), Bilateral vocal folds nodules (4 cases), Bilateral thickening of both vocal folds(3 cases), Vocal fold cyst.(4 cases). Asthmatic children with abnormal finding in (VLS) had a statistical significant lower values of FEV1 and MMEF with higher percentage of poor asthma control. Voice analysis showed impairment of voice acoustics in asthmatic children with significant difference between asthmatic and control as regards voice analysis data with significant higher jitter and shimmer dB (measure of voice amplitude and detector of early hoarseness of voice) . Conclusion Asthmatic patients may have an associated Laryngeal or vocal folds abnormalities which are considered a comorbid condition and one of the causes of poor asthma control. Voice analysis may help in detection of subclinical hoarseness of voice which may be sequelae of chronic cough or side effects of inhaled steroids.

Objective: To compare paraoxonase activity and changes in oxidative status in asthmatic children and healthy children by determining serum paraoxonase activity and total oxidative status, total antioxidant capacity and lipid hydroperoxidation. Methods: Forty two asthmatic children were compared with 32 healthy children of similar age and sex. To evaluate the paraoxonase and oxidative status, total antioxidant capacity and lipid hydroperoxidation were examined. Serum paraoxonase activity was evaluated by measuring the rate of paraoxon hydrolosis. Oxidative status was evaluated by the method developed by Erel. Lipid hydroperoxide was measured by an iodometric method. Results: In comparison with the healthy control group, the paraoxonase activity of the asthmatic children was found to be low (163.7 ± 73.0 (U/L) and 349.2 ± 153.9 (U/L), P = 0.002) and total oxidant status (9.0 ± 3.5 ?mol H2O2 Eq/L and 13.4 ± 7.0 ?mol H2O2 Eq/L, P =0.002), total antioxidant capacity (5.5 ± 2.5 µmol Trolox Eq/L and 1.0 ± 0.6 µmol Trolox Eq/L, P < 0.001), and lipid hydroperoxidation values (9.9 ± 3.4 ?mol H2O2 Eq/L and 4.4 ± 1.5 ?mol H2O2 Eq/L, P < 0.001) were found to be high. The high density lipoprotein (HDL) concentration of the asthmatic children was lower than that in the control group (40.1 ± 9.2 mg/dl and 54.5 ± 15.9 mg/dl, P < 0.001) Conclusion: In asthmatic children, when total oxidant status, total antioxidant capacity and lipid hydroperoxidation levels increase, paraoxonase activity decreased.

Background: Asthma is a chronic immunological disorder of the lungs. Vitamin D has several effects on the innate and adaptive immune systems. Little is known about vitamin D level and its impact on severity of asthma in children. This study aimed to determine vitamin D levels in asthmatics versus control children; studying the relation if any between these levels and asthma severity.Methods: This cross-sectional study was conducted on 60 asthmatic children and 20 apparently healthy children as controls. Asthma patients were divided into 3 groups (mild, moderate, severe; 20 each). Asthma severity was based on GINA criteria. Vitamin D level was measured to all study group.Results: The difference between the mean values of vitamin D level in control and asthmatic patients was statistically significant (p<0.001). This difference between control group and each asthma subgroup and between asthma subgroups versus each other were statistically significant being highest in control and lowest in patients with severe asthma (p<0.001). Differences in vitamin D status in control and all asthmatic patients were statistically significant (p<0.001). The difference between control group and each asthma subgroup according to vitamin D status were statistically significant (p<0.001). Concerning asthma subgroups the difference in vitamin D status between severe versus mild and moderate asthma were statistically significant (p<0.001), while between mild and moderate asthma it was not.Conclusions: Significantly lower vitamin D level in asthmatic children compared to controls and a differential decrease in vitamin D levels in asthmatic children being lowest in severe asthma was confirmed.

Asthma In Children

Background: Obese asthma is a complex syndrome with certain phenotypes that differ in children and adults. There is no clear evidence regarding the presence of additive or synergistic pathological interaction between obesity and asthma in children. Objectives: Our aim was to demonstrate the interaction of obesity and asthma in children in terms of airway and systemic inflammation by a controlled observational study. Methods: Four groups were formed: asthma obese (AO), asthma nonobese (ANO), non-AO (NAO), nonasthma nonobese (NANO). Spirometry test, fractional exhaled nitric oxide (FeNO) test, skin prick test, serum inflammatory biomarkers (C-reactive protein, C3, C4, adiponectin, leptin, resistin, periostin, YKL-40, Type 1, and Type 2 cytokines) were conducted and evaluated in all participants. Sputum inflammatory cells (sputum eosinophils and neutrophils) were evaluated in patients who could produce induced sputum and obesity-asthma interactions were determined. Results: A total of 153 participants aged 6–18 years were included in the study, including the AO group (n = 46), the ANO group (n = 45), the NAO group (n = 30), and the NANO group (n = 32). IL-4 (p < 0.001), IL-5 (p < 0.001), IL-13 (p < 0.001), resistin (p < 0.001), and YKL-40 (p < 0.001) levels were higher in patients with asthma independent of obesity. The lowest adiponectin level was found in the AO group and obesity-asthma interaction was detected (p < 0.001). Sputum eosinophilia (p < 0.01), sputum neutrophilia (p < 0.01), and FeNO levels (p = 0.07) were higher in asthmatic patients independent of obesity. In the group with paucigranulocytic inflammation, resistin and YKL-40 levels were significantly lower than in the group without paucigranulocytic inflammation (p < 0.01). Conclusion: No interaction was found between obesity and asthma in terms of airway inflammation. Interaction between obesity and asthma was shown in terms of adiponectin level and resistin/adiponectin and leptin/adiponectin ratios. It was found that serum YKL-40 and resistin levels could be associated with airway inflammation.

Seventy four asthmatic children aged 7 to 11 years were examined along with controls matched by age and sex. Clinical and laboratory investigations preceded a 28-day follow-up where data about morning and evening peak expiratory flow rate (PEF), symptoms and treatment were recorded. The coefficient of variation of PEF was found to be an objective measurement of asthma severity that has statistically significant correlation with both symptoms (r s= .36) and treatment (r s= .60). Moreover, it separates mild and severe asthmatics, as confirmed by statistically significant differences (p= .008 or less) in symptoms, treatment, skin allergy and airways response to exercise. Skin allergy and airways responsiveness to exercise were found to be predictors of both disease and severity. By means of logistic regression analysis it was possible to establish the probabilities for both asthma and severe asthma when children presenting and not presenting these characteristics are compared. One single positive skin test represent a probability of 88% for the development of asthma and a probability of 70% for severe disease. A PEF reduction of 10% after an exercise test implies a probability of 73% for disease and a probability of 64% for severe disease. Increases in these variables imply geometrically increased risks and their presence together have a multiplicative effect in the final risk.

Chronical Disease

Asthma is a chronical disease of the airways characterized by reversible obstruction of the bronchi and airway inflammation. In recent decades, the scientific interest of the vitamin D system and its role in development of asthma and other alergic diseases has been increased. Aims of this study are to mesure and compare the serum level of 25 OHD in asthmatic and healthy children and corelate the level of 25OHD and total IgE in asthmatic children. This prospective study includes 70 children at age 2 to 14, of which 32 are children with diagnosed asthma and 38 healthy children. In both  of the groups the serum level of 25 OHD was measured  and by the results 18 % of the healthy children (C) and 28% of the asthma children (E) had 25OHD  deficiency, 45%  of C and 50% of E were insufficient and 37 % of C / 22% of E were with normal 25 OHD serum level. The mean level of 25OHD in C was 27,83 +/- 10,24 and in E 20,9 ng/ml +/- 10,72. The mean levels in both groups had statistic significant difference with p-value < 0,05. According to age no statistic significant difference was found in both of the groups. There was a statisticaly significant decreased serum level of 25 OHD in asthmatic females.In the examined group (children with asthma) there was a negative linear correlation (association) of the level of 25OHD and total IgE serum level with r=- 0,55  Vitamin D serum level measurements in asthma patients gives the possibility for discovering the connection between its deficiency and development of asthma symptoms.
