Methods: We conducted a retrospective analysis, examining the medical records of 49 children (15 males, 34 females) with rheumatologic disorders who got infected with SARS-CoV2. They were recruited, over a period of 17 months, from the Children's Hospitals of Ain Shams, Mansoura and Assiut Universities in Egypt. Data recorded were the type and duration of rheumatologic, antirheumatic treatment received, and COVID-19 presentation including severity, and outcome. Complete blood count (CBC), erythrocyte sedimentation rate (ESR), C reactive protein (CRP), lactate dehydrogenase enzyme (LDH), serum ferritin, and D-dimer levels were recorded. Results: Our series included 25 SLE, 16 JIA, two polyarteritis nodosa, two dermatomyositis, two mixed connective tissue disease, one systemic sclerosis, and one HSP patients. They had median (IQR) age of 13 (10-14) years. Twenty-nine (59.2%) patients had active disease flare. Forty-one (83.7%) patients were on corticosteroids, and 35 (71.4%) were on add-on immunosuppressives. Twenty-nine patients were hospitalized with median (IQR) admission duration of 25 (14-38) days. They included 8 mild/asymptomatic, 4 moderate, 6 severe, and 11 critical COVID-19 cases. Seven cases with critical COVID-19 passed away with mortality rate of 14.3 %. The deceased cases had higher neutrophil/lymphocyte ratio (p=0.003), higher CRP levels (p= 0.041) and higher D-dimer (p=0.001) and ferritin levels (0.002) as compared to survivors. Conclusion: Although reported to be milder in children, COVID-19 seems to have higher mortality among children with rheumatic disorders compared to rates reported in the general population. We could not find evidence for the impact of immunosuppressive treatment on COVID-19 related mortality, yet our findings need to be validated by wider scale prospective studies.","PeriodicalId":52068,"journal":{"name":"Egyptian Journal of Pediatric Allergy and Immunology","volume":null,"pages":null},"PeriodicalIF":0.3,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45839572","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Lysine Acetyl transferase 2B (KAT2B), is one of the histone acetylases that regulate the gene transcription. It was linked to autoimmune diseases with variable expression in relation to various disease parameters. We sought to investigate the KAT2B expression on peripheral blood mononuclear cells (MNCs) in patients with pSLE and its relation to biomarkers of lupus flare, major organ involvement, SLE disease activity index (SLEDAI), and therapeutic modalities used . Methods: This cross-sectional comparative study comprised 30 patients with SLE who fulfilled at least four of the System Lupus International Collaborating Clinics (SLICC) classification criteria. Thirty age- and sex-matched healthy children were included as a control group. The patients were subjected to clinical evaluation including the SLEDAI, and lupus flare laboratory markers. KAT2B expression on MNCs was measured by ELISA in the pSLE patients as well as the control group . Results: KAT2B expression on the MNCs was significantly lower among the pSLE patients than the healthy controls (p <0.001). Patients with moderate and severe lupus activity had significantly lower KAT2B expression on MNCs than those with mild activity as judged by the SLEDAI (p=0.03). The KAT2B expression was not significantly correlated to the studied biomarkers of lupus activity (ESR, anti-DNA or C3) but was negatively correlated to the extent of renal affection in terms of the 24 hours urinary protein level (p=0.024). The findings are limited by the sample size. Conclusion: From this pilot study, the low expression of KAT2B on MNCs seems to be linked to pediatric SLE disease activity. Wider scale and prospectively designed studies are needed to validate this observation and to explore the effect of disease remission on KAT2B expression in pSLE activity.","PeriodicalId":52068,"journal":{"name":"Egyptian Journal of Pediatric Allergy and Immunology","volume":null,"pages":null},"PeriodicalIF":0.3,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43895668","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The search for a non-invasive urinary marker of lupus nephritis is an appealing point of research. There are few studies that have evaluated the role of urinary ceruloplasmin (CP) as a biomarker for LN. Being expressed at high levels by parietal epithelial cells of Bowman’s capsule it could possibly detoxify molecules as they pass through the glomerular filter. CP is a highly effective antioxidant that can prevent oxidative damage to lipids, DNA, and proteins.

Survivin, antiapoptotic protein, is associated with significant tissue damage and/or poor response to treatment. We sought to investigate its potential role as indicator of disease activity and predictor of MAS in SoJIA . Methods: We conducted a prospective controlled study that comprised 22 physician-diagnosed SoJIA patients and 20 healthy age and sex matched children as a control group. Patients were subjected to clinical and laboratory assessment every 2 months for one year to detect disease relapse or MAS. Serum survivin was measured at enrollment and in case of activity or MAS development. Other inflammatory markers of activity and MAS were also assayed including CRP, ESR, serum ferritin, ferritin/ESR ratio and triglycerides . Results: Over one year of follow up, ten Patients (45.5%) developed both systemic and articular activity with or without MAS, one patient (4.5%) developed systemic activity only, 5 patients (22.7%) had only articular activity and six patients (27.3%) remained in remission. Serum survivin, ferritin, ESR and the ferritin/ESR ratio were high during activity and even higher in the patients who developed MAS. Ferritin/ESR ratio above three had a 100% sensitivity and 83% specificity in the diagnosis of MAS [Area under the curve (AUC) = 0.96]. Serum survivin level above 25 pg/ml had 100% sensitivity and 90% specificity in detection of disease activity [AUC = 0.96] and a serum level above 67 pg/ml had 100% sensitivity and 94.7% specificity in the prediction of MAS [AUC = 0.99] .

The higher the total score the worst is the HRQOL of the patient. We also used the SMILEY scoring questionnaire, which consists of 26 items for children with SLE up to 18 years of age, in assessment of the patients’ QOL . Results: The patients’ ages ranged between 12-18 years (mean ± SD = 12.2 ± 1.9 years); 57 were females and 3 were males. All domains of the SLEQOL were significantly altered in patients evaluated during disease activity. The SMILEY scores, as well, were significantly affected by disease activity and correlated positively to the total SLEQOL score results.

Objective: The purpose of this study was to investigate the serum levels of INF-β and NOD2 single nucleotide gene polymorphism (SNP) among Egyptian asthmatic children who presented with wheezy and cough phenotypes . Methods: A group of 131 Egyptian asthmatic children (67 wheezy phenotype and 64 cough phenotype) together with 39 controls were enrolled and analyzed for the genotypes of NOD2 (rs2066845) polymorphisms using real time PCR via TaqMan assays. Serum INF-β levels were determined by ELISA technique . Results: Serum INF-β levels were significantly lower in both wheezy and cough phenotypes compared to control group (Z=1.19, p=0.233). Concerning the studied NOD2 SNP (rs2066845), both GG and GC genotypes showed significantly higher frequencies among asthmatic cases compared to healthy controls (p= 0.002, 0.021, respectively).

Thus, we sought to determine serum periostin level in children with bronchial asthma in correlation with asthma severity and pulmonary function tests . Methods: This controlled cross-sectional study was conducted on 50 children with bronchial asthma and 30 age-matched healthy controls who were recruited from the Children’s Hospital, Aswan University, during the period from May 2018 to April 2019.
