Clinical experience with hepatorenal tyrosinemia from a single Egyptian center. PLoS One 2022; 17:e0268017. [PMID: 35536841 PMCID: PMC9089876 DOI: 10.1371/journal.pone.0268017] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/10/2021] [Accepted: 04/20/2022] [Indexed: 11/19/2022] [Imported: 09/15/2023] Open
Abstract
Although very recently, in Egypt, sick newborn screening has included screening for hepatorenal tyrosinemia, yet, it is not yet included in nationwide neonatal screening and hence diagnosis may be delayed. The aim of this study was to analyze data of all cases presenting with hepatorenal tyrosinemia to the Pediatric Hepatology Unit, Cairo University, Egypt from 2006 to 2019. Data were retrieved from patients’ files including age of onset of symptoms, clinical signs, blood counts, liver functions, serum phosphorous, alpha-fetoprotein, succinylacetone and abdominal ultrasound. During this period, 76 patients were diagnosed with hepatorenal tyrosinemia if succinylacetone in dry blood spot was elevated above 1 μmol/L. These 76 cases came from 70 families; consanguinity was reported in 61 families. In our cohort we reported 30 affected siblings with a similar clinical presentation, who died undiagnosed. Presentation was acute in 26%, subacute in 30% and chronic in 43%. Abdominal distention was the commonest presenting symptom (52.6%). Coagulopathy was the commonest derangement in liver functions; hyperbilirubinemia and raised transaminases were less common. Ultrasound findings included hepatic focal lesions in 47% and enlarged echogenic kidneys in 39% and 45.3% respectively. Only 20 children were treated with Nitisinone because of unavailability and high costs; seven out of them underwent liver transplantation. In conclusion, although hepatorenal tyrosinemia is a rare inborn error of metabolism, in a large population country with high rate of consanguinity; this disease is not uncommonly diagnosed. The current treatment is not readily available because of the costs in a resource-limited country. Neonatal screening and subsidization of the costly medication need to be considered.

Abstract
Abstract
Background
Alagille syndrome (ALGS) is a rare autosomal dominant multisystem disorder that affects the liver, heart, eyes, vertebrae, and kidneys and is associated with characteristic facies. This work aimed to study the spectrum of the clinical features of ALGS in an Egyptian cohort of patients in conjunction with partial sequencing of the JAG1 gene.
Methods
This study included 17 pediatric ALGS patients diagnosed on clinical grounds: facial features, cholestatic liver disease, and cardiac, vertebral, and ocular findings. Molecular analysis was conducted in 10 selected exons of the JAG1 gene.
Results
The clinical features of ALGS included cholestatic liver disease (100%), facial dysmorphism (100%), cardiac abnormalities (88.2%), butterfly vertebrae (64.7%), posterior embryotoxon (35.2%), poor growth (41%), xanthomata (11.8%), and hiatus hernia (11.8%). Five novel pathogenic JAG1 mutations were identified in this study, including two nonsense mutations, one splicing mutation, one frameshift insertion, and one frameshift deletion. In two patients, the mutations were confirmed to be de novo, as the mutations could not be detected in both parents.
Conclusion
Five novel JAG1 pathogenic variants were identified in this study. This is the first molecular study to report pathogenic mutations in the JAG1 gene within an Egyptian cohort of children with ALGS.

Covid-19 pandemic in Egyptian children with liver diseases: Incidence and impact on health care service delivery in a low/middle income country. Arab J Gastroenterol 2022; 23:1-6. [PMID: 35120837 PMCID: PMC8758320 DOI: 10.1016/j.ajg.2022.01.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/31/2021] [Revised: 12/12/2021] [Accepted: 01/10/2022] [Indexed: 01/08/2023] [Imported: 09/15/2023]
Abstract
BACKGROUND AND STUDY AIMS The coronavirus disease 2019 (COVID-19) pandemic has had considerable effects on health care services given the need for re-allocation of resources and interruption of medical care. COVID-19 poses a challenge to patients with liver disease who are at risk of infection and more severe disease course. The current study aimed to assess the incidence of COVID-19 in children with liver diseases and evaluate the extent to which health care delivery was affected during lockdown. PATIENTS AND METHODS This cross-sectional analytical study conducted at the Pediatric Hepatology Unit, Cairo University Children's Hospital utilized a questionnaire to determine the incidence of COVID-19 in patients with liver diseases and the impact of COVID-19 on the patients' liver condition and health care service delivery. A presumed score was implemented to identify patients with probable COVID-19. RESULTS Data from 349 children with liver diseases were analyzed. The overall incidence of COVID-19 was 8%. Patients with documented and probable COVID-19 were compared to improbable COVID-19 cases. Notably, COVID-19 cases were younger and had higher incidence rates of cholestatic liver diseases. COVID-19 patients experienced significantly higher rates of hepatic complications (43%) and had significantly greater need for medical services during the lockdown. All COVID-19 patients recovered after a median (IQR) duration of 3 (4) days, except for one patient who succumbed to COVID-19 and hepatic complications. CONCLUSIONS COVID-19 affected the younger hepatic patients with cholestatic disorders of infancy. Hepatic complications were more common among COVID-19 infected children. Alternative ways of communication require development to prioritize patients who needs a hospital visit and monitoring. Clinical scores may help diagnosis of COVID-19 in low/middle income countries like Egypt to compensate for the deficient laboratory diagnostic facilities.

Abstract
Background and aim Autoimmune hepatitis (AIH) has variable clinical manifestations and should be considered in the diagnostic work-up of any patient with cryptogenic liver disease. The aim of the study was to determine the clinical, biochemical, histopathological characteristics and treatment outcome of AIH in Egyptian children. Patients and methods This observational study was conducted at the Pediatric Hepatology Unit at Cairo University Pediatric Hospital, Egypt. All children (<18 years of age) presenting from 2009 to 2016 with established diagnosis of AIH were included. Medical history, clinical examination, and results of investigations were retrieved from patients’ files. The main outcome measures included the rate of remission, relapses, and mortality. Results The study included 34 children with AIH. Twenty patients (58%) presented with chronic liver disease. There was a history of concomitant autoimmune diseases in 5 patients. Transaminases were elevated in all patients. There was synthetic dysfunction in 58%. Twenty-four patients (70.5%) had AIH-1, while nine patients (26.4%) had AIH-2 and one patient (2.9%) had autoantibody negative AIH. Piecemeal necrosis was observed in the liver biopsy of 79% of our cohort. Approximately 80% achieved biochemical remission (88% received combined therapy of prednisolone and azathioprine). About half of the patients developed relapses. One patient died of liver cell failure. Conclusion In children with liver disease, a diagnosis of AIH should be considered. In those patients, AIH-1 is more common than AIH-2. Prednisolone monotherapy or combined with azathioprine could achieve remission, but relapse is still common. Treatment non-adherence is the main risk factor for relapse.

Abstract
BACKGROUND Solid organ transplantation (SOT) service has been disrupted during the current coronavirus disease 2019 (COVID-19) pandemic, which deferred the service in most centers worldwide. As the pandemic persists, there will be an urgency to identify the best and safest practices for resuming activities as areas re-open. Resuming activity is a difficult issue, in particular, the decision of reopening after a period of slowing down or complete cessation of activities. OBJECTIVES To share our experience in resuming living donor liver transplantation (LDLT) in the context of the COVID-19 pandemic in the Liver Transplantation Unit of El-Manial Specialized Hospital, Cairo University, Egypt, and to review the obstacles that we have faced. MATERIAL AND METHODS This study is a single-center study. We resumed LDLT by the 26th of August 2020 after a period of closure from the 1st of March 2020. We have taken a lot of steps in order to prevent COVID-19 transmission among transplant patients and healthcare workers (HCWs). RESULTS In our study, we reported three LDLT recipients, once resuming the transplantation till now. All our recipients and donors tested negative for SARS-CoV-2 by nasopharyngeal RT-PCR a day before the transplantation. Unfortunately, one of them developed COVID-19 infection. We managed rapidly to isolate him in a single room, restricting one team of HCWs to deal with him with strict personal protective measures. Finally, the patient improved and was discharged in a good condition. The second patient ran a smooth course apart from FK neurotoxicity which improved with proper management. The third patient experienced a sharp rise in bilirubin and transaminases on day 14 that was attributed to drug toxicity vs. rejection and managed by discontinuing the offending drugs and pulse steroids. In addition, one of our head nurses tested positive for SARS-CoV-2 that was manageable with self-isolation. CONCLUSION Careful patient, donor, personnel screening is mandatory. Adequate supply of personal protective equipments, effective infection control policies, and appropriate administrative modifications are needed for a safe return of LDLT practice.

Improvement in Liver Stiffness in Pediatric Patients with Hepatitis C Virus after Treatment with Direct Acting Antivirals. J Pediatr 2021; 233:126-131. [PMID: 33577805 DOI: 10.1016/j.jpeds.2021.02.012] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/14/2020] [Revised: 02/04/2021] [Accepted: 02/05/2021] [Indexed: 02/08/2023] [Imported: 09/15/2023]
Abstract
OBJECTIVES To assess the degree of liver stiffness using transient elastography in Egyptian children infected with hepatitis C virus (HCV) at baseline and 1 year after achievement of sustained virologic response (SVR) with direct acting antivirals. STUDY DESIGN This prospective study included children infected with HCV who received treatment with sofosbuvir/ledipasvir and achieved SVR. At baseline and 1 year after achievement of SVR, the extent of hepatic fibrosis was assessed by transient elastography using FibroScan to measure liver stiffness, in addition to noninvasive markers including aspartate aminotransferase/platelet ratio index (APRI) and fibrosis-4 (FIB-4) index. RESULTS The study included 23 cases that had variable degrees of fibrosis at baseline; their ages ranged between 10 and 18 years. At baseline, 13 patients had F1; 3 patients had F1-F2; 1 patient had F2; 3 patients had F3; 2 had F3-F4; and 2 patients with F4. One year after achievement of SVR, there was a statistically significant improvement in liver stiffness, APRI, and FIB-4 index (P = .03, <.001, .02, respectively). In 13 patients (56.5%), the liver stiffness improved; in 7 patients, it was stationary; and the remaining 3 patients showed mild increase in liver stiffness that was, however, associated with improvement in APRI and FIB-4 index. Comorbid conditions and previous treatment with interferon were not associated with increased liver stiffness 1 year after SVR. CONCLUSIONS Egyptian children infected with HCV genotype 4 achieved significant regression in liver stiffness after treatment with direct acting antivirals.

Abstract
BACKGROUND Hepatic dysfunction has a significant role in intensive care unit patients' morbidity and mortality. AIM To study the frequency, risk factors and outcome of secondary hepatic dysfunction in children admitted to the pediatric intensive care unit. METHODS Secondary hepatic dysfunction was defined as the development of abnormal liver functions in a patient without a previous liver disease during intensive care unit stay. The following data were collected: age, gender, indication of admission, type of organ dysfunction, presence of sepsis, shock, need for inotropic support or mechanical ventilation, administered medications and mortality scores. Liver function tests were done on admission and at 7-day intervals. RESULTS One hundred and fifty-one patients were included. Forty-three (28.5%) acquired secondary hepatic dysfunction. Several risk factors were significantly associated with secondary hepatic dysfunction: sepsis (p<0.001), cardiovascular events (p<0.001), hypoxia (p<0.001), number of administered antibiotics (P = 0.001), use of inotropes (p<0.001) and mechanical ventilation (p = 0.001). Secondary hepatic dysfunction was significantly associated with mortality and prolonged length of stay (P=<0.001). CONCLUSION Secondary hepatic dysfunction is a common finding in the pediatric intensive care unit. Sepsis, cardiovascular events and hypoxia, are the main risk factors for secondary hepatic dysfunction. Mortality and prolonged length of stay are strongly related to secondary hepatic dysfunction.

Abstract
PURPOSE The outcome predictors of Kasai portoenterostomy (KPE) for biliary atresia (BA) are controversial. This study aimed to identify possible short-term outcome predictors of KPE for BA in infants. METHODS This retrospective study included infants with BA who underwent KPE between January 2015 and December 2017 and were followed up for at least 6 months after surgery at the Pediatric Hepatology Unit, Cairo University Pediatric Hospital, Egypt. The short-term outcome was jaundice clearance within 6 months following surgery. All data were compared between the jaundice free group and those with persistent jaundice to identify the predictors of jaundice clearance. RESULTS The study included 75 infants. The mean age at the time of surgery was 82.43±22.77 days (range, 37-150 days), and 28 (37.3%) infants cleared their jaundice within 6 months postoperative. Age at surgery did not significantly affect the outcome (p=0.518). Infants with persistent jaundice had significantly higher pre-operative levels of aspartate aminotransferase (AST) than those who were jaundice free (p=0.041). Receiver operating characteristic curve analysis showed that preoperative AST ≤180 IU/L was predictive of a successful KPE, with sensitivity 74.5% and specificity 60.7%. Infants with bile plugs in liver biopsy had a 6-fold higher risk of persistent jaundice than those without bile plugs (95% confidence interval: 1.59-20.75, p=0.008). CONCLUSION Jaundice clearance after KPE for BA can be predicted using preoperative AST and presence of bile plugs in liver biopsy.

Abstract
BACKGROUND AND OBJECTIVE Drug-drug interactions need to be considered to optimize the pharmacotherapeutic outcome of direct-acting antivirals. The aim of this study was to report on possible drug-drug interactions between ledipasvir/sofosbuvir and other medications received by children and adolescents with hepatitis C virus, in addition to suggested management for these drug-drug interactions. METHODS Hepatitis C virus-infected children and adolescents, 12-17 years of age and/or weighing ≥ 35 kg, who presented to the Pediatric Hepatology Unit at Cairo University Pediatric Hospitals for ledipasvir/sofosbuvir treatment were included. Medication history was taken including long-term medications for chronic conditions and on-demand medications for inter-current illnesses. Medications were reviewed by the Kasr Alainy Drug Information Center to identify possible drug-drug interactions with prescribed ledipasvir/sofosbuvir and their management. HEP Drug Interactions provided by the University of Liverpool, Lexicomp®, and Medscape were the utilized references. Each drug-drug interaction was assigned a risk rating of A, B, C, D, or X. RESULTS Sixty hepatitis C virus-infected children and adolescents assigned to receive ledipasvir/sofosbuvir were enrolled. Thirty percent of patients had associated chronic co-morbid conditions. The overall number of medications received was 48; 39 were prescribed as long-term medications with a median of 3 (interquartile range 4.24) medications per patient. Proton pump inhibitors, antacids, histamine H2 receptor antagonists, sodium bicarbonate, and colchicine were reported to be associated with a drug-drug interaction risk D necessitating therapy modification, which occurred prior to administration. CONCLUSIONS Early identification and prompt response to drug-drug interactions with the aid of pharmacists optimize the pharmacotherapeutic outcome and eliminate possible morbidities when using direct-acting antivirals in children and adolescents with hepatitis C virus.

Abstract
BACKGROUND AND AIM Renal abnormalities can occur at any time point during the course of Wilson disease (WD). We aimed to fill a literature gap in this respect by studying urinary abnormalities in children and adolescents with WD. METHODS This study included 60 children with WD presenting to the Pediatric Hepatology Unit, Cairo University. The following data were retrieved from the patients' files including age, sex, liver function tests, serum ceruloplasmin, 24-h urinary copper, serum creatinine, blood urea nitrogen, urinalysis, urinary albumin/creatinine ratio, urinary calcium/creatinine ratio, urinary β2-microglobulin, liver and renal biopsy results when available. RESULTS All studied cases had no symptoms related to renal involvement. Microscopic hematuria was detected in 11% and 12% at baseline and within 5 years of therapy, respectively. Moderate microalbuminuria was detected in 34%, 50%, and 33% at baseline, within 5 years and > 5 years after therapy, respectively. Hypercalciuria was detected in 23% at baseline, 34% in those patients treated for up to 5 years and 37.5% > 5 years of therapy. Age and international normalized ratio were significantly higher in patients with high calcium/creatinine ratio compared with those with normal values at initial evaluation. Frequency of elevated urinary β2-microglobulin was 36%, 36%, and 37% in patients at baseline, up to 5 years and > 5 years of therapy, respectively. CONCLUSION Asymptomatic urinary abnormalities are present in patients with WD at any time point of the disease and during treatment with d-penicillamine. They have to be searched for, as early intervention may prevent progression to renal insufficiency.

Abstract
AIM Guidelines for managing the hepatitis B (HB) virus infection in children are still evolving. We aimed to assess the eligibility of children with HB virus infections for treatment based on the current guidelines. METHODS This observational study took place in 2016 and focused on children with isolated chronic HB infections, who attended the paediatric hepatology units at two centres in Egypt. We recruited all treatment-naïve children aged one year to 18 years who had completed at least 12 months of follow-up. RESULTS The study comprised 103 children aged between 1.5-18 years. Of these, 51 (50%) had the HB e antigen-positive chronic infection, 28 (27%) had the HB-negative chronic infection, 11 (11%) had the HB e antigen-positive chronic hepatitis and none had the HB e antigen-negative chronic hepatitis. The remaining 13 (12%) children did not fulfil the criteria for chronic HB definitions. Only two of the children were candidates for treatment: both had HB e antigen-positive chronic hepatitis and had undergone liver biopsies. CONCLUSION Only two of the 103 children with chronic HB were eligible for treatment according to the current guidelines and every measure should be taken to prevent the HB virus infection in children.

Abstract
BACKGROUND Symptomatic bradycardia has been reported in adults treated for chronic hepatitis C using sofosbuvir based regimens. AIM We studied the cardiac safety of sofosbuvir/ledipasvir in Egyptian children, treated for chronic hepatitis C. METHODS The study included 40 hepatitis C virus infected children and adolescents 12-17 years old, using the combination of sofosbuvir (400 mg)/ledipasvir (90 mg) in a single oral tablet (Harvoni) taken daily for 12 weeks. All subjects underwent a baseline standard 12-lead surface Electrocardiography that was repeated at 4 and 12 weeks of therapy. Electrocardiography parameters (Heart Rate, RR interval, PR interval, QRS, QT interval, corrected QT interval, QT dispersion, JT interval, corrected JT interval, JT dispersion, Tpeak-Tend interval) were compared at the 3 different time points during antiviral therapy. RESULTS No symptoms related to the cardiovascular system were reported during treatment. There were no cases of symptomatic bradycardia/syncope. Heart rate was noted to be significantly lower and RR and QT intervals were significantly longer in the baseline electrocardiography. Heart rate was significantly lower and RR interval was significantly longer in patients with higher viral load. CONCLUSION No adverse cardiovascular events were observed in this group of HCV infected children and adolescents treated with sofosbuvir/ledipasvir. None of the patients developed bradyarrhythmias during treatment.

Abstract
OBJECTIVES Recently, direct acting antivirals (DAAs), sofosbuvir (SOF) combined with ledipasvir (LED), were approved for treatment of hepatitis C virus (HCV)-infected children 12 years of age and older or weighting at least 35 kg for all HCV genotypes. The aim of this study was to assess the safety and efficacy of SOF/LED in genotype 4 HCV-infected Egyptian children and adolescents. METHODS This observational study included 40 consecutive HCV-infected children of age 12 to <18 years old or weighing >35 kg, both treatment-naive and treatment-experienced. All of the children were hepatitis B virus-negative and had normal renal functions and heart rate. Patients received oral, fixed-dose combination tablet of SOF/LED (400 mg SOF, 90 mg LED [Harvoni]) once daily for 12 weeks. Potential side effects were recorded at weeks 4, 8, and 12 weeks of treatment. The study primary outcome was sustained virological response 12 weeks (SVR12) after end-of-treatment. RESULTS The study included 40 children and adolescents, 24 were boys (60%); their age ranged between 11.5 and 17.5 years (mean 13.9 ± 1.5). Baseline viral load ranged between 9630 and 24,600,000 IU/mL. HCV RNA became negative in 39 patients (97.5%) at 4 weeks and in all patients (100%) at weeks 8, 12, and SVR12. Asthenia was the commonest side effect, reported in 52.5% followed by headache in 47.5%. CONCLUSIONS Treatment with all-oral DAAs (SOF/LED) for 12 weeks was well tolerated in Egyptian children and adolescents infected with genotype 4 HCV, with 100% SVR12 and negligible side effects.

[PMID: 30289914 PMCID: PMC6173381 DOI: 10.1371/journal.pone.0203808] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/16/2018] [Accepted: 08/28/2018] [Indexed: 11/18/2022] [Imported: 09/15/2023] Open
Abstract
Ascitic fluid infection is a major cause of morbidity and mortality in cirrhotic patients, requiring early diagnosis and therapy. We aimed to determine predictors of ascitic fluid infection in children with chronic liver disease. The study included 45 children with chronic liver disease and ascites who underwent 66 paracentesis procedures. Full history taking and clinical examination of all patients were obtained including fever, abdominal pain and tenderness and respiratory distress. Investigations included: complete blood count, C-reactive protein, full liver function tests, ascitic fluid biochemical analysis, cell count and culture. Our results showed that patients' ages ranged between 3 months to 12 years. Prevalence of ascitic fluid infection was 33.3%. Gram-positive bacteria were identified in six cases, and Gram-negative bacteria in five. Fever and abdominal pain were significantly more associated with infected ascites (p value = 0.004, 0.006). Patients with ascitic fluid infection had statistically significant elevated absolute neutrophilic count and C-reactive protein. Logistic regression analysis showed that fever, abdominal pain, elevated absolute neutrophilic count and positive C-reactive protein are independent predictors of ascitic fluid infection. Fever, elevated absolute neutrophilic count and positive C-reactive protein raise the probability of ascitic fluid infection by 3.88, 9.15 and 4.48 times respectively. The cut-off value for C-reactive protein for ascitic fluid infection was 7.2 with sensitivity 73% and specificity of 71%. In conclusion, prevalence of ascitic fluid infection in pediatric patients with chronic liver disease and ascites was 33.3%. Fever, abdominal pain, positive C-reactive protein and elevated absolute neutrophilic count are strong predictors of ascitic fluid infection. Therefore an empirical course of first-line antibiotics should be immediately started with presence of any of these predictors after performing ascitic fluid tapping for culture and sensitivity. In absence of these infection parameters, routine ascitic fluid analysis could be spared.

Abstract
BACKGROUND AND STUDY AIMS Hepatobiliary cholestatic disorders produce excess copper (Cu) retention in the liver, which is toxic and may cause hepatitis, fulminant hepatic failure, cirrhosis and death. In this study, we measured hepatic Cu and tested its correlation with serum Cu (S. Cu) and serum ceruloplasmin (S. ceruloplasmin) in cholestatic infants. PATIENTS AND METHODS 41 cholestatic infants were enrolled as cases and 11 healthy infants as control subjects. S. Cu and S. ceruloplasmin were done for all infants and hepatic Cu was measured in the liver specimen in cases. RESULTS Cases were 63.5% males with their age ranging between 1 and 7 months, while control subjects were 45.5% males with an age range between 3 and 18 months. Among cases, 41.5% had biliary atresia and 58.5% had intrahepatic cholestasis. Cholestatic infants had significantly higher levels of S. Cu and S. ceruloplasmin than control subjects and their hepatic Cu concentration was significantly higher than literature control. Infants with biliary atresia showed higher levels of Cu indices, with no statistical significance. Serum and hepatic Cu levels positively correlated with each other and with S. ceruloplasmin. Results of ROC curve showed that S. Cu was highly sensitive and specific for predicting hepatic Cu concentration at cut-off 181 μg/dl. CONCLUSION Serum and hepatic Cu concentrations were markedly elevated in patients with cholestasis and positively correlated with each other and with S. ceruloplasmin. S. Cu level can predict hepatic Cu concentration.

Abstract
Biallelic mutations in the SLC30A10 gene cause an inborn error of Mn metabolism characterized by hypermanganesemia, polycythemia, early-onset dystonia, and liver cirrhosis (HMDPC). To date, only 14 families from various ethnic groups have been reported. Here, we describe 10 patients from 7 unrelated Egyptian families with HMDPC. Markedly elevated blood Mn levels, the characteristic basal ganglia hyperintensity on T1-weighted images, and variable degrees of extrapyramidal manifestations with or without liver disease were cardinal features in all patients. Eight patients presented with striking early diseased onset (≤2 years). Unexpectedly, early hepatic involvement before the neurological regression was noted in 3 patients. Mutational analysis of SLC30A10 gene revealed 6 novel homozygous mutations (c.77T > C (p.Leu26Pro), c.90C > G (p.Tyr30*), c.119A > C (p.Asp40Ala), c.122_124delCCT (p.Ser41del), c.780_782delCAT (p.Iso260del) and c.957 + 1G > C). Treatment using 2,3 dimercaptosuccinic acid as a manganese chelating agent showed satisfactory results with improvement of biochemical markers, hepatic manifestations and relative amelioration of the neurological symptoms. Our findings present a large cohort of patients with HMDPC from same ethnic group. The majority of our patients showed severe and early presentation with clear phenotypic variability among sibship. Moreover, we extend the phenotypic and mutational spectrum and emphasize the importance of early diagnosis and treatment of this potentially fatal disorder.

Abstract
BACKGROUND Minimal hepatic encephalopathy (MHE) is not associated with overt neuropsychiatric symptoms but rather with subtle changes in psychometric and/or neurophysiologic tests. We aimed to diagnose MHE in children with extrahepatic portal vein obstruction (EHPVO) and to evaluate the effect of lactulose on MHE. METHODS A prospective study was carried out on 30 patients with EHPVO (21 males; mean age 10±2.5 years). The study was carried out in the Pediatric Hepatology Unit, Cairo University Pediatric Hospital, Cairo, Egypt, between 2011 and 2013. All patients were subjected to clinical and laboratory assessment, neuropsychmetric testing using the arabic version of Wechsler intelligence tests, neurophysiological testing by visual electroencephalogram and P300 event related potentials (ERP). RESULTS The prevalence of MHE among children with EHPVO was 20% (6/30). After randomization to treatment and no-treatment groups using lactulose, all tests were repeated after three months. Among four patients with MHE who received lactulose, three (75%) improved. On the other hand, one of the patients in the no-treatment group developed MHE. Only one patient in the treatment arm had to discontinue lactulose because of severe diarrhea. CONCLUSIONS This pilot study revealed that the prevalence of MHE was 20%. Improvement on psychometic tests was seen in 75% of our patients (3/4) after treatment with lactulose. Lactulose treatment was well tolerated.

Abstract
INTRODUCTION Liver is an important organ for metabolism. It has a major role in integrating the various biochemical pathways of metabolism. Thus, children with chronic liver disease are at high risk for developing undernutrition, with important prognostic implications. AIM To evaluate the nutritional status of hospitalized paediatric liver disease patients and its effect on outcome. MATERIALS AND METHODS We prospectively analysed the nutritional status of 59 consecutive patients during their first 24 hours of admission, at the Hepatology Unit, using the following indices: weight/age, height/age, weight/height, Body Mass Index (BMI), arm circumference and triceps skinfold, subcapular skinfold, and mid upper arm circumference. RESULTS According to the measurements: 35.6% were underweight, 49% were stunted, 10% were wasted by weight for length/height percentile and 5% were wasted by body mass index, 49% had percentage of ideal body weight below normal, 27% had head circumference below 3rd percentile, 59.4% had triceps skinfold thickness below 5th percentile, 66% had subscapular skinfold thickness below 5th percentile; 56% had arm circumference below 5th percentile. There was no correlation between these growth parameters and mortality. However, we found a positive correlation between decreased triceps skinfold thickness and prolonged hospital stay. Malnourished patients, according to triceps skinfold thickness, were significantly younger and they were the ones who suffered from cholestatic disorders of infancy. CONCLUSION Only triceps skinfold thickness was found to be a useful predictor for a prolonged hospital stay. Serial measurements may be more effective.

Abstract
BACKGROUND AND STUDY AIMS Liver biopsy remains the most reliable method to diagnose various hepatic disorders in children. We aimed to assess the technical success and complication rate of ultrasound (US) assisted percutaneous liver biopsy versus transthoracic percussion guided technique in paediatrics. PATIENTS AND METHODS This randomized controlled study included all cases performing liver biopsy at Paediatric Hepatology Unit, Cairo University Paediatric Hospital over 12months. RESULTS Patients were 102 cases; 62 were males, with age range 18days to 12years. Fifty seven procedures were done using the percussion guided technique and 45 cases were US assisted. The total number of complicated biopsies was 14 (13.7%), with more serious complications occurring in the percussion group. Complications were more frequent with younger age, lower platelet count, number of passes and occurrence of hypotension. CONCLUSION US assisted percutaneous liver biopsy, although more costly, but may be safer to perform particularly in younger age.

Abstract
Treatment of hepatitis C virus (HCV) in end-stage renal disease (ESRD) patients is an important issue before kidney transplantation (KT). The aim of the study is to assess the efficacy and tolerability of HCV treatment with pegylated interferon (PEG IFN)-α 2b in children with ESRD. The study included 17 children, aged 3-18 years with ESRD on hemodialysis (HD), with chronic HCV. They received 40 μg/m2 of PEG IFN-α 2b once-weekly subcutaneous injections for 48 weeks. Early virological response (EVR) was achieved in 76.5%. At week 24, 8 patients had negative HCV RNA. Six patients received KT during therapy. Treatment was discontinued in 2 patients: one for anemia and another for retinopathy. Two patients completed 48 weeks of therapy and both achieved end-of-treatment response and sustained virological response (SVR). Constitutional symptoms were the most frequently reported side effects. Neutropenia occurred in 10 patients (58.8%), drop in hemoglobin in 10, and thrombocytopenia in 9. HCV-infected children with ESRD on HD have high EVR (76.5%) on IFN monotherapy. SVR could not be assessed due to the high dropout rate related mainly to early transplantation. Constitutional symptoms and hematological side effects were the most frequently reported side effects.

Abstract
BACKGROUND There is deficiency of data about congenital heart defects (CHDs) in cholestatic disorders of infancy other than Alagille syndrome (AGS). We aimed to define the prevalence and types of CHDs in infants with various causes of cholestatic disorders of infancy. METHODS This cross-sectional study was conducted on 139 infants presenting with cholestasis whether surgical or non-surgical. The study was carried out at the Pediatric Hepatology Unit, Cairo University Children's Hospital, Egypt. Full examination and investigations were done in an attempt to reach an aetiologic diagnosis for cholestasis, in addition to a comprehensive echocardiographic study. RESULTS The age at the onset of cholestasis ranged from 1 day to 7 months. Males constituted 61.2%. Biliary atresia (BA) was diagnosed in 39 patients (28%), AGS in 16 patients (11.5%), 27 patients had miscellaneous diagnoses and 57 cases had indeterminate aetiology. CHDs were detected in 55 patients (39.5%). Shunt lesions were detected in 24 patients (43.6%), pulmonary stenosis in 18 patients (32.7%) and combined lesions in 9 patients (16.4%). Three patients (5.5%) had abnormal cardiac situs. Only seven patients had clinical presentation suggestive of CHD. CHDs were detected in 14 patients with BA (35.9%), 15 patients with AGS (93.7%) and 26 patients in the remaining group (30.9%). CONCLUSION CHDs are not uncommon among cholestatic infants and are mostly asymptomatic. Echocardiographic examination of cholestatic infants is recommended particularly for patients with BA before undergoing hepatic portoenterostomy as presence of CHD may impact the anaesthetic planning and affect the outcome of hepatobiliary surgery.
