Background: Respiratory tract infections (RTIs) are among the most commonly encountered major public health problems, with a higher prevalence of lower RTIs among children and more generally the poor. The present study aimed to describe the pattern of respiratory tract infections in Egyptian children aged under 5 years and explore possible associations between socio-demographics and nutritional status and types of RTIs. Methods: Over 6 months beginning in September 2018 (including one winter season), a cross-sectional, observational, epidemiological study was conducted on a sample of patients with upper and lower RTIs diagnosed clinically and/or radiologically in the outpatient clinics at Cairo University Children's Hospital in Egypt. An interview questionnaire was employed to collect socio-demographic and nutritional data. Heights/lengths and weights were measured and analyzed using the World Health Organization's (WHO) Anthro Plus [Computer Program]. Patients with pneumonia (n = 28) were compared to 97 healthy children of the same age and sex. Results: The total number of children diagnosed with upper and lower respiratory infections was 611. Malnutrition was present in 12.4% of all children with upper and lower RTIs. Lower RTI and malnutrition were substantially more prevalent among children aged under 2 years (p = 0.048 and p < 0.001, respectively). The strongest predictor of lower RTI was a younger age (OR 0.797, CI 0.713–0.89, p < 0.001). Conclusion: At our center, approximately one-third of infections in under-fives were lower RTI. Malnutrition was one of the significant risk factors for lower RTI in children below 2 years. The nutritional status of infants and young children should be improved by encouraging exclusive breastfeeding during the first 6 months of life and strengthening the healthcare and nutritional counseling available for vulnerable children, particularly in rural regions.

Background and Objective: Diabetic nephropathy (DN) is the most common cause of end stage renal failure or even death among patients with type 2 diabetes mellitus. Genetic predisposition is widely studied among these patients to identify manageable aspects of the disease pathogenesis. This study was carried out to test the association of engulfment and cell motility 1 (ELMO1) gene polymorphism with DN among Egyptians. ELMO1 is required for phagocytosis of apoptotic cells and cell motility.Methods: This case-control study was conducted on type 2 diabetic patients who attended Suez Canal University Hospital, Egypt, between November 2016 and October 2017. Peripheral blood was collected from 200 diabetic patients (without nephropathy), 200 patients with DN, and 100 healthy controls for DNA extraction. The single nucleotide polymorphism of ELMO1 (rs741301) was genotyped using real-time polymerase chain reaction and the allele discrimination technique.Results: GG genotype was significantly associated with DN (odds ratio [OR] = 2.7; 95% confidence interval [CI]: 1.4-5.3) (P = .016). The OR for the high-risk allele (G) was 1.9 with 95% CI from 1.5 to 2.9 (P < .001).Conclusion: ELMO1 gene (rs741301) polymorphism is a candidate variant in the predisposition to DN.

Aim: To identify the clinical status and immunological profile of a cohort of children with chronic hepatitis B virus (HBV) infection to assess the short-term consequences of this infection. Material and methods: This prospective case-control study included 30 children in the age range 1-15 years with positive HBsAg attending the Hepatology clinic of Alexandria University Children's Hospital. Twenty children received lamivudine (3 mg/kg, oral, once a day), and 10 children were lamivudine-resistant and received entecavir treatment (10-11 kg/0.3 mg to > 30 kg/1 mg). They were followed up every 3 months for 1 year. Results: The study showed that 97% of the studied cases were discovered accidentally during routine investigations and only 3% presented by acute hepatitis. Ninety percent of them had family member infection with HBV, of which 70% were the mother. Eighty-seven percent of cases had no clinical signs, and only 13% of cases had hepatomegaly. All of the cases were HBsAg positive, 50% were HBeAg positive, 56.7% were HBeAb positive, 33.3% were HBcAb positive, and 100% were HBsAb negative. Conclusions: Most of children with HBV infection had associated family member infection and were accidentally discovered. Despite a marked decrease in HBV DNA level after treatment, there was no clearance of HBsAg and no HBsAb seroconversion. Screening for the HBsAb level in children with family members with HBV is recommended. [ABSTRACT FROM AUTHOR]

Introduction: Constipation is a common disorder among children, and most of the cases are functional in aetiology. Few studies have reported the manometric data of normal and constipated children. Aim: To evaluate the manometric parameters in children with functional constipation and to assess any possible changes in these parameters after treatment. Material and methods: A prospective descriptive study was conducted at a single centre, enrolling 50 children diagnosed with functional constipation based on Rome IV criteria. Their age ranged from 6 to 14 years with a mean of 7.31 ±1.72 years. High-resolution manometry was performed on all children at the initial presentation and after six months of treatment. Results: The studied children showed markedly abnormal rectal sensation parameters (increased first sensation, first urge, intense urge, and maximum tolerable volume) during rectal balloon distension. These parameters were even higher in children with stool incontinence (p = 0.005). Manometric data after 6 months of treatment showed that the resting and squeeze pressures were increased when compared to pre-treatment recordings; however, both were statistically insignificant (p = 0.474 and p = 0.155, respectively). Abnormalities in rectal sensations and the manometric parameters reached near normal values following treatment. Conclusions: Anorectal manometry is sensitive in predicting improvement in patient condition even before complete clinical cure, and it has a prognostic role in the management of childhood constipation. More research is still needed before recommending anorectal manometry as a routine diagnostic or prognostic tool in paediatric constipation management. [ABSTRACT FROM AUTHOR]

Aim The aim of the current study is to investigate the prevalence of familial Mediterranean fever gene ( MEFV) mutations in a cohort of Egyptian children with inflammatory bowel disease ( IBD), and to characterize familial Mediterranean fever ( FMF)- IBD patients, helping better understanding of IBD pathogenesis. Methods The study enrolled 17 patients with ulcerative colitis ( UC), 15 with Crohn's disease( CD), 10 with indeterminate colitis ( IC) and 33 healthy children as controls. All cases and controls were tested for 12 FMF gene mutations by reverse hybridization after multiplex polymerase chain reaction amplification and DNA sampling. Results Eighty-eight percent of the IBD patients carried the mutations, with Sequence variant V627 A being the commonest versus 42.4% of controls. No associations were found between MEFV gene mutations, and phenotypic characteristics of IBD patients. Conclusion IBD patients, in populations with a high background carrier rate of MEFV variants, should be screened for MEFV gene mutations, especially those diagnosed as indeterminate colitis. Testing larger numbers of healthy Egyptian children for MEFV gene mutation is important to further determine the allele frequency in Egypt. [ABSTRACT FROM AUTHOR]

Objective.Cognitive impairment commonly occurs in hepatitis C virus (HCV) patients. The objective of this study was to estimate the prevalence and sociodemographic and clinical correlates of cognitive impairment in HCV patients before and after 12 weeks of interferon treatment in comparison with a control group.Methods.Hundred and sixteen consecutive HCV patients were included in the study and divided into treated and untreated groups. All patients were assessed using sociodemographic and clinical questionnaire, Montreal Cognitive Assessment Scale (MOCA) and Hospital Anxiety and Depression Scale (HADS) before and after 12 weeks of treatment or observation.Results.Thirty-eight percent of treated patients showed cognitive impairment at baseline, which increased to 69% after 12 weeks of interferon treatment. This cognitive impairment was reflected in the total MOCA score and in visuo-constructional skills, attention, concentration, working memory, language, and short-term memory, which was not shown by untreated group after 12 weeks of observation. Cognitive impairment was associated with low education, but not with depression, anxiety, or virological response.Conclusions. Cognitive impairment is common in HCV patients and increases significantly after interferon treatment. It is not related to depression or anxiety in HCV patients. Future research should focus on prevention, treatment and outcome of cognitive impairment in HCV patients, particularly those receiving interferon therapy. [ABSTRACT FROM AUTHOR]

Introduction: Diarrhoea continues to cause significant morbidity in Egypt. Aim: To determine the frequency and distribution of different enteropathogens in acute diarrhoeal episodes, utilising an expanded testing regimen, and to correlate clinical signs and symptoms associated with the detected pathogens. Material and methods: The case-control study enrolled 356 patients < 5 years old with acute diarrhoea and 356 age and sexmatched healthy controls. Both cases and controls underwent a full history and physical examination, and provided two rectal swab specimens and a stool sample. Laboratory analysis included stool culture, microscopy, and indirect methods. Results: Rotavirus was detected in 11% of patients. Enterotoxigenic Escherichia coli (ETEC), Campylobacter, Shigella, and Salmonella were detected in 7%, 3.7%, 1.1%, and 1.4% of patients, respectively; and in 11.1%, 3.1%, 0.6%, and 0.6% of controls, respectively, with no significant statistical difference. Cryptosporidium was detected in 3.9% of cases. Mixed infection was detected in 5.9% of cases and 0.9% of controls, with a significant difference (p < 0.001). No pathogen was detected in 66.3% of cases and in 83.5% of controls. Rotavirus infection was associated with recurrent vomiting, dehydration, and hospitalisation. Bacterial diarrhoea was associated with vomiting (52%) in ETEC infections, fever (80%) in Salmonella infections, mucus (100%) and blood (50%) in stools of Shigella infections, and convulsions (15%) in Campylobacter infections. Conclusions: Rotavirus is a prominent cause of diarrhoea among Egyptian children. Despite utilising an expanded testing regimen, more work is still needed for identification of other enteropathogens that constitute other causative agents of diarrhoea. [ABSTRACT FROM AUTHOR]

Objectives: In this study, we aimed to evaluate the plasma levels of a soluble receptor for advanced glycation end products (sRAGE) in patients with systemic lupus erythematosus (SLE) and to investigate their relationship with different clinical, laboratory, and therapeutic parameters. Patients and methods: A total of 120 patients with SLE (111 females, 9 males) and 40 age- and gender-matched healthy controls were included. The plasma sRAGE levels were measured using a commercially available enzyme-linked immunosorbent assay (ELISA). The possible relationship between plasma sRAGE levels with SLE clinical and laboratory characteristics were also assessed. The effectiveness of different therapeutic modalities on plasma sRAGE levels was analyzed. Results: The SLE patients had significantly lower plasma levels of sRAGE than the healthy controls (p=0.003). The patients with a skin rash or serositis had significantly higher sRAGE levels than those without (p=0.036 and p=0.017, respectively). The SLE patients who were treated over a longer period of time showed higher levels of sRAGE than those treated for shorter periods (p=0.000). No significant difference in levels was found among the patients treated with corticosteroids and those treated with combined therapy (p=0.89). There was a significant negative correlation between the sRAGE level and the total white blood cell (WBC) count (r=-0.356; p=0.003), lymphocytes (r=0.341; p<0.001), and neutrophils (r=-0.289; p=0.006). Conclusion: We found significantly decreased plasma sRAGE levels in the SLE patients in our study. This suggests that sRAGE levels may play a role in the pathogenesis of the disease.

Background/Aim: We aim to investigate the safety of outpatient blind percutaneous liver biopsy (BPLB) in infants and children with chronic liver disease (CLD). Patients and Methods: BPLB was performed as an outpatient procedure using the aspiration Menghini technique in 80 infants and children, aged 2 months to 14 yrs, for diagnosis of their CLD. Patients were divided into three groups: Group 1 (<1 year), group 2 (1-6 yrs), and group 3 (6-14 yrs). The vital signs were closely monitored 1 hr before biopsy, and then 1, 2, 6, and 24 hrs after biopsy. Twenty-four hours pre- and post-biopsy complete blood counts, liver enzymes, prothrombin time (PT), and abdominal ultrasonography, searching for a biopsy-induced hematoma, were done for all patients. Results: No mortality or major morbidities were encountered after BPLB. The rate of minor complications was 17.5% including irritability or "pain" requiring analgesia in 10%, mild fever in 5%, and drowsiness for >6 hrs due to oversedation in 2.5%. There was a statistically significant rise in the 1-hr post-biopsy mean heart and respiratory rates, but the rise was non-significant at 6 and 24 hrs except for group 2 where heart rate and respiratory rates significantly dropped at 24 hrs. No statistically significant difference was noted between the mean pre-biopsy and the 1, 6, and 24-hrs post-biopsy values of blood pressure in all groups. The 24-hrs post-biopsy mean hemoglobin and hematocrit showed a significant decrease, while the 24-hrs post-biopsy mean total leucocyte and platelet counts showed non-significant changes. The 24-hrs post-biopsy mean liver enzymes were non-significantly changed except the 24-hrs postbiopsy mean PT which was found to be significantly prolonged, for a yet unknown reason(s). Conclusions: Outpatient BPLB performed by the Menghini technique is safe and well tolerated even in infants and young children. Frequent, close monitoring of patients is strongly recommended to achieve optimal patient safety and avoid potential complications. [ABSTRACT FROM AUTHOR]

Objectives: Celiac disease (CD) is increasingly reported from North Africa, including Egypt. Autoimmune hepatitis (AIH) is considered a high risk factor for CD. We aimed to investigate the frequency of CD diagnosis in AIH.Methods: We prospectively enrolled 26 AIH patients aged 3.5–21 (mean 9.98 ± 3.94) years and 20 healthy age- and sex-matched controls. Serodiagnosis of CD was based on the most sensitive tests namely immunoglobulin A (IgA) human tissue transglutaminase antibody (IgA-tTGA) by enzyme-linked immunosorbent assay and/or IgA endomysial antibody (IgA-EMA) by immunofluoresence and confirmed the diagnosis by upper gastrointestinal endoscopy and histo-pathological findings in jejunal biopsy.Results: IgA-EMA was positive in four patients (15.4%), whereas IgA-tTGA was positive in two of them (7.7%). Histopathology was confirmatory in three (11.5%) seropositive patients.Conclusion: The high prevalence (11.5%) of CD among Egyptian children with AIH indicates that CD exists in high-risk groups in our region and must be carefully looked into.
