Hepatitis C Virus (HCV) Vertical Transmission in 12-Month-Old Infants Born to HCV-Infected Women and Assessment of Maternal Risk Factors

Background. Hepatitis C virus (HCV) is an underappreciated cause of pediatric liver disease, most frequently acquired by vertical transmission (VT). Current guidelines that include the option of screening infants for HCV RNA at 1–2 months are based on data prior to current real-time polymerase chain reaction (PCR)-based testing. Previous studies have demonstrated VT rates of 4%–15% and an association with high maternal viral load. We evaluated HCV RNA in infants with HCV VT and assessed maternal risk factors in a prospective cohort in Cairo, Egypt

Schimke immune-osseous dysplasia: A case report

Schimke immune-osseous dysplasia (SIOD) is a rare autosomal recessive disorder characterized by spondylo-epiphyseal dysplasia (SED), progressive renal insufficiency beginning as steroid-resistant nephrotic syndrome (SRNS) and defective cellular immunity. This article reports a case from Egypt with a mild form of SIOD. A 14.5-year-old male patient presented with disproportionate short stature, SRNS (focal and segmental glomerulosclerosis), laboratory evidence of cellular immune deficiency and radiologic characteristics of SED. He died at the age of 16.5 years with bone marrow failure and severe pneumonia. To the best of our knowledge, this is the first case of SIOD to be reported from Egypt

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

Fifteen years of kidney biopsies in children: A single center in Egypt

This study retrospectively investigates the indications and results of renal biopsy in children to determine the patterns of childhood kidney disease in a single tertiary children′s hospital in Egypt. We included all the patients who underwent ultrasound-guided renal biopsy from 1998 to 2012. All the kidney biopsies were studied under light microscopy, while immunofluorescence and electron microscopy were performed when indicated. A total of 1246 renal biopsies were performed over 15 years, on 1096 patients. The mean age of the patients at the time of biopsy was 9.2 ± 3.7 years. The main indication for a biopsy was the steroid-resistant nephrotic syndrome (n = 354, 28.4%), followed by the atypical nephrotic syndrome (n = 250, 20.1%), and renal abnormalities in the systemic diseases (n = 228, 18.3 %). In the 1226 pathologically diagnosed specimens, primary glomerulonephritis was the most common finding (n = 826, 67.4%), followed by secondary glomerulonephritis (n = 238, 19.4%). The most common causes of primary glomerulonephritis were Minimal Change Disease (MCD) (n = 267, 21.8%), diffuse proliferative glomerulonephritis (n = 188, 15. 3%), and focal proliferative glomerulonephritis (n = 164, 13.3%). Lupus nephritis (n = 209, 17%) was the most common cause of secondary glomerulonephritis. We conclude that the steroid-resistant nephrotic syndrome was the most frequent indication for biopsy and minimal change disease was the most common histopathological finding in our population

Aberrant p16INK4A methylation: Relation to viral related chronic liver disease and hepatocellular carcinoma

Background: Hepatocellular carcinoma (HCC) is currently the fifth most common solid tumor worldwide and the third leading cause of cancer related deaths. Several studies have shown that the tumor suppressor gene p16INK4A is frequently downregulated by aberrant methylation of the 5′-cytosine-phosphoguanine island within the promoter region. Aim: To find out the frequency of methylated p16INK4A in the peripheral blood of HCC and cirrhotic patients and to evaluate its role in hepatocarcinogenesis. Patients and Methods: This study was performed on 58 subjects: 30 HCC patients, 20 cirrhotic patients, and eight healthy volunteers. Methylation of p16INK4A was examined using methylation specific polymerase chain reaction (PCR) (MSP). Comparison of quantitative variables between the study groups was done using Mann-Whitney U test for independent samples when not normally distributed. For comparing categorical data, Chi-square (χ2 ) test was performed. Exact test was used instead when the expected frequency was less than 5. Results: Methylation of p16INK4A was found in 6.7% of HCC patients, 5% of liver cirrhosis (LC) patients, and none of the healthy volunteers; 66.67% of the p16INK4A-methylated cases (2/3) were positive for anti-hepatitis C virus (HCV) antibodies (one of them had HCC). All HCC cases with aberrant p16INK4A methylation show very high serum alpha fetoprotein (AFP) level (9,080; 30,000 μg/mL). There were no significant associations between the status of p16INK4A methylation and tumor size. Conclusion: Hypermethylation of p16INK4A was found to be infrequent among Egyptian patients with HCC

Selective screening for inborn errors of metabolism by tandem mass spectrometry in Egyptian children: a 5 year report

In order to enhance awareness and promote registry for inborn errors of metabolism (IEMs) in Egypt, we aimed to evaluate the prevalence and main clinical findings of IEMs detectable by tandem mass spectrometry (MS/MS) among high risk pediatric patients presenting to our tertiary care facility at Cairo University Children's Hospital over a period of 5 years and to compare the disease burden in Egypt in the absence of a national screening program for inherited metabolic disorders with other populations.status: publishe
