Acute lower respiratory tract infection due to respiratory syncytial virus in a group of Egyptian children under 5 years of age

<p>Abstract</p> <p>Background and aim</p> <p>Respiratory syncytial virus (RSV) is one of the most important causes of acute lower respiratory tract infections (ALRTI) in infants and young children. This study was conducted to describe the epidemiology of ALRTI associated with RSV among children ≤ 5 years old in Egypt.</p> <p>Patients and Methods</p> <p>We enrolled 427 children ≤ 5 years old diagnosed with ALRTI attending the outpatient clinic or Emergency Department (ED) of Children Hospital, Cairo University during a one- year period. Nasopharyngeal aspirates were obtained from the patients, kept on ice and processed within 2 hours of collection. Immunoflourescent assay (IFA) for RSV was performed.</p> <p>Results</p> <p>91 cases (21.3%) had viral etiology with RSV antigens detected in 70 cases (16.4%). The RSV positive cases were significantly younger than other non-RSV cases (mean age 8.2 months versus 14.2 months, p <0.001). RSV cases had significantly higher respiratory rate in the age group between 2-11 months (mean 58.4 versus 52.7/minute, p < 0.001) and no significant difference in the mean respiratory rate in the age group between 12-59 months. More RSV cases required supplemental oxygen (46% versus 23.5%, p < 0.001) with higher rate of hospitalization (37.1% versus 11.2%, p < 0.001) than the non-RSV cases. 97% of RSV cases occurred in winter season (p < 0.001).</p> <p>Conclusion</p> <p>RSV is the most common viral etiology of ALRTI in children below 5 years of age, especially in young infants below 6 months of age. It is more prevalent in winter and tends to cause severe infection.</p

Ocular manifestations in Egyptian children with chronic hepatitis C treated with pegylated interferon and ribavirin

Objectives The aim of this study was to report the prevalence of interferon (IFN)-associated retinopathy and other serious ocular complications in a prospectively studied group of children with chronic hepatitis C virus (HCV) receiving pegylated IFN α2b and ribavirin. Patients and methods Prospective comprehensive ophthalmologic examinations were performed by the first author (D.H.A.R.K.) for all included children bilaterally at 0, 12, 24, and 48 weeks after the start of treatment, and at 6 months after the end of treatment. Data recorded included visual complaints, visual acuity, pupillary reactions, and retinal findings. Results All patients aged 3–17 years who were healthy enough to participate in an ophthalmological examination were included. The number of children who remained on treatment and underwent ophthalmologic examinations was 136 after 48 weeks of treatment (90 boys and 46 girls). No patient had ischemic retinopathy at the screening eye examination before initiation of treatment. After 24 weeks of treatment, two (1.5%) patients developed anterior uveitis and another two (1.5%) patients developed retinal ischemia with cotton-wool spots. Conclusion Ophthalmologic complications are infrequent in children who are treated with pegylated IFN α2b for HCV (3%). Because of the potential severity of ischemic retinopathy and uveitis, prospective ocular assessment should remain a part of the monitoring strategy for children who are treated with IFN for HCV

A comparative study of endoscopic ultrasonography versus endoscopic retrograde cholangiopancreatography in children with chronic liver disease

Background: Endoscopic ultrasonography (EUS) is a less invasive modality and may be equal or superior to endoscopic retrograde cholangiopancreatography (ERCP) in visualizing the biliary tree. Its role and feasibility in children need to be accurately defined. Aim: This study aimed at evaluation of EUS in assessment of children with chronic liver disease (CLD) in comparison with ERCP. Materials and Methods: The present study was carried out between September 2004 and February 2006 on 40 children suffering from CLD. Patients were selected from the Pediatric Hepatology Unit, Cairo University Children′s Hospital, Egypt. They were included if they had: sonographic (n = 8) or histopathological evidence of biliary pathology (n = 2); autoimmune hepatitis with high gamma glutammyl transpeptidase (GGT) levels and/or not responding to immunosuppressive therapy (n = 15); cryptogenic CLD (n = 13); neonatal cholestasis with relapsing or persistent course (n = 2). They all underwent EUS and ERCP. Results: Three of six cases with intrahepatic biliary radicle dilatation had Caroli′s disease by EUS and ERCP; and the other 3 had sclerosing cholangitis. EUS was equal to ERCP in diagnosis of biliary pathology. However, one false positive case was described to have dilatation and tortuosity of the pancreatic duct by EUS as compared to ERCP. EUS could detect early pancreatitis in 5 cases. One case with cryptogenic liver disease proved to have sclerosing cholangitis by both EUS and ERCP. Conclusion: EUS is an important diagnostic tool for biliary pathology and pancreatitis in children with pancreatico-biliary pathology. ERCP should be reserved for therapeutic purposes

Pattern of ocular manifestations in Egyptian infants with cholestatic disorders

Background Neonatal and infantile cholestasis can be associated with ocular findings that might aid in the diagnosis of diseases such as Alagille syndrome (AGS) and Niemann–Pick disease (NPD). Aim We aimed to investigate the frequency of ocular manifestations in infants with cholestasis. Patients and methods This cross-sectional study included cholestatic infants presenting to the Pediatric Hepatology Unit, Pediatric Hospital, Cairo University. All infants underwent ophthalmological examinations including anterior segment examination using a hand-held slit lamp, ocular motility, cycloplegic refraction, intraocular pressure measurement, and ocular ultrasonography. Results The study included 112 infants with various cholestatic disorders of infancy. Of them, 73 (65.2%) were male. The median age was 2 months. A diagnosis was reached in 39 cases: 14 had AGS, 14 had biliary atresia, four had NPD, four had posthemolytic cholestasis, two had cytomegalovirus neonatal hepatitis, and one case had hepatorenal tyrosinemia. Thirteen cases were probably having progressive familiar intrahepatic cholestasis types 1 or 2 in view of their persistent cholestasis in the presence of normal γ-glutamyl transpeptidase level. Sixty were left with a diagnosis of ‘idiopathic neonatal hepatitis’. Ophthalmological assessment showed abnormal findings in 39 cases (34.8%). The most common finding was unilateral/bilateral optic nerve drusen in 12 cases (10.7%), followed by posterior embryotoxon in 11 (9.8%) cases. Ocular findings were observed in several cholestatic disorders, including in 64.3% of patients with AGS, 50% with NPD, 36.7% of infants with idiopathic neonatal hepatitis, and 14.3% with biliary atresia. Conclusion Ophthalmological assessment should be part of the workup for the diagnosis and assessment of cholestatic infants

Genetic polymorphisms in non-alcoholic fatty liver disease in obese Egyptian children

Background/Aim : Polymorphisms in the promoter of microsomal triglyceride transfer protein (MTP) lead to decreased MTP transcription, less export of triglyceride from hepatocytes, and greater intracellular triglyceride accumulation. Therefore, functional polymorphisms in MTP may be involved in determining susceptibility to nonalcoholic steatohepatitis (NASH). The aim of this study is to examine the effect of some genetic influences among a group of obese Egyptian children. Patients and Methods: A cross-sectional study was conducted on 76 overweight and obese children presenting to the Pediatric Endocrinology Unit, Cairo University Children′s Hospital, Egypt, as well as on 20 healthy controls. Anthropometric measurements were taken for all the patients and they underwent clinical examination, ultrasonographic examination of the liver, and liver biopsy when appropriate. Liver functions, blood glucose, serum insulin, C-peptide, and lipid profile were assessed and HOMA-IR calculated. Blood samples from biopsy-proven NASH patients and controls were analyzed by polymerase chain reaction (PCR) and restriction fragment length polymorphism for the −493 G/T polymorphism in the promoter of MTP and the 1183 T/C polymorphism in the mitochondrial targeting sequence of manganese superoxide dismutase (MnSOD). Results : Eight had biopsy-proven simple steatosis and 7 had NASH. NASH patients had a much higher incidence of the MTP G/G genotype (P = 0.002, CI: 2.9-392) compared with the controls. NASH patients also had a 100% prevalence of the MnSOD T/T genotype. Conclusion: Certain genotypes in MTP and MnSOD are significantly more prevalent among obese children with NASH and may be responsible for such a phenotype

Outpatient Blind Percutaneous Liver Biopsy in Infants and Children: Is it Safe?

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 (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 post-biopsy 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

The Association of Metabolic Syndrome, Insulin Resistance and Non-alcoholic Fatty Liver Disease in Overweight/Obese Children

Background/Aim: To study the prevalence of metabolic syndrome (MS), insulin resistance (IR) and non-alcoholic fatty liver disease (NAFLD) in overweight/obese children with clinical hepatomegaly and/or raised alanine aminotransferase (ALT). Patients and Methods: Thirty-three overweight and obese children, aged 2-13 years, presenting with hepatomegaly and/or raised ALT, were studied for the prevalence of MS, IR and NAFLD. Laboratory analysis included fasting blood glucose, serum insulin, serum triglycerides (TG), total cholesterol, high-density lipoprotein cholesterol (HDL-c), low-density lipoprotein cholesterol (LDL-c) and liver biochemical profile, in addition to liver ultrasound and liver biopsy. Results: Twenty patients (60.6%) were labeled with MS. IR was present in 16 (48.4%). Fifteen (44%) patients had biopsy-proven NAFLD. Patients with MS were more likely to have NAFLD by biopsy (P=0.001). Children with NAFLD had significantly higher body mass index, waist circumference, ALT, total cholesterol, LDL-c, TG, fasting insulin, and lower HDL-c compared to patients with normal liver histology (P< 0.05) and fitted more with the criteria of MS (80% vs. 44%). IR was significantly more common among NAFLD patients (73% vs. 28%). Conclusion: There is a close association between obesity, MS, IR and NAFLD. Obese children with clinical or biochemical hepatic abnormalities are prone to suffer from MS, IR and NAFLD
