RESUMO
Background: The role of viruses is well known in health and disease. The aim of this report was to describe the profile of viruses in the gut of healthy Saudi children. Methods: In 20 randomly selected school age children from Riyadh, stool samples were collected in cryovials and stored at -80° C. At the time of analysis, the samples were sent by express mail in a temperature-controlled container to the laboratory in the USA, Viral DNA was isolated and shotgun metagenomic sequencing was performed. The abundance of each organism was expressed as an average relative percentage across the viral phylogenetic tree from phyla to species. Results: The median age of the children was 11.3 (range 6.8-15.4) years, and 35% were males. Caudovirales were the most abundant bacteriophage order (77%) and Siphoviridae, Myoviridae, and Podoviridae families predominated, accounting for 41%, 25%, and 11%, respectively. Among the viral bacteriophage species, the most abundant were the Enterobacteria phages. Conclusion: The profile and abundance of the gut virome in healthy Saudi children reveal important differences from the literature. Further studies from different populations with larger sample sizes are needed to understand the role of gut viruses in the pathogenesis of disease in general and in the response to fecal microbiota therapy in particular.

BACKGROUND: Studies have reached different conclusions regarding the accuracy of dysbiosis in predicting the diagnosis of Crohn's disease (CD). The aim of this report is to assess the utility of mucosal and fecal microbial dysbiosis as predictors in the diagnosis of this condition in Saudi children. METHODS: Tissue and fecal samples were collected prospectively from children with final diagnosis of CD and from controls. Bacterial DNA was extracted and sequenced using Illumina MiSeq chemistry. The abundance and diversity of bacteria in tissue and fecal samples were determined in relation to controls. Sparse logistic regression was calculated to predict the diagnosis of CD based on subject's microbiota profile. RESULTS: There were 17 children with CD and 18 controls. All children were Saudis. The median age was 13.9 and 16.3 years for children with CD and controls respectively. Sex distribution showed that 11/17 (65%) of the CD and 12/18 (67%) of the control subjects were boys. The mean area under the curve (AUC) was significantly higher in stool (AUC = 0.97 ± 0.029) than in tissue samples (AUC = 0.83 ±0.055) (P < 0.001). CONCLUSIONS: We found high AUC in mucosal and fecal samples. The higher AUC for fecal samples suggests higher accuracy in predicting the diagnosis of CD.

BACKGROUND AND AIM: According to previously reported studies in the literature, a significant number of patients do not receive enteral nutrition in pediatric intensive care unit (PICU) because of avoidable barriers. Optimal nutrition is a fundamental goal in PICU. This study aims to identify the barriers of enteral nutrition in PICU. SETTING AND DESIGN: A cross-sectional study of the results of a 25-item questionnaire-based survey distributed during the Annual International Critical Care Conference by the Saudi Critical Care Society. METHODS AND MATERIAL: A 7-point Likert-type scale was used to rank the participants' responses, and the relative importance index (RII) approach was used to analyze the relative contribution of each indicator to its main theme.The factor and parallel analysis methods were used to assess the factorial and unidimensionality of the enteral feeding barriers scale. RESULTS: A total of 223 PICU healthcare workers from various intensive care settings responded to the survey. The top-three perceived barriers for commencing enteral feeding were due to the patient being hemodynamically unstable (M = 3.6 and SD = 1.70), delays and difficulties in obtaining small bowel access in patients not tolerating other types of enteral nutrition (M = 3.4 and SD = 1.52), or severe fluid restriction, particularly in postoperative cardiac surgery (M = 3.3 and SD = 1.59). The top perceived overall barriers to enteral feeding were the dietician-related issues (M = 3.3, SD = 1.32), barriers related to enteral feeding delivery (M = 3.16 and SD = 1.13), and medical practice-related (M = 3 and SD = 1.10) issues. The lowest reported overall barriers were the resource-related obstacles (M = 2.7 and SD = 1.26). CONCLUSION: Being hemodynamically unstable and other dietician-related reasons were the top overall barriers in commencing enteral feeding.
RESUMO
BACKGROUND/AIM: Delay in the diagnosis of inflammatory bowel disease (IBD) is associated with complications. Our aim was to describe the pattern and risk factors associated with delay in the diagnosis of IBD in Saudi children. PATIENTS AND METHODS: This was a multicenter study with a retrospective/prospective design. Data on diagnostic delay in children with Crohn's disease (CD) and ulcerative colitis (UC) were retrieved from physician's notes. Multivariate regression analysis was used to assess the risk factors associated with long delay in diagnosis. RESULTS: There were 240 and 183 Saudi children with CD and UC, respectively. The median delays in diagnosis were 8 and 5 months in CD and UC, respectively, significantly longer in children with CD than UC (P < 0.001). Long diagnostic delays (>75th percentile) were 24 and 8.8 months for CD and UC, respectively. Ileal location was a significant risk factor in CD and the age of onset above 10 years was protective in UC. CONCLUSIONS: Long diagnostic delay in IBD was mainly due to the longer delay in gastroenterologist consultation. Review of the referral system is needed to focus on measures to reduce long delays in diagnosis. The ileal location as a risk factor in CD and age older than 10 years as protective in UC should help recognition and early referral.

OBJECTIVES: To determine the outcomes of endoscopic dilatation of esophageal strictures in children. METHODS: Children younger than 18 years of age diagnosed with esophageal strictures over a period of 7 years (June 2010 to June 2017) were reviewed and analyzed retrospectively. The study took place at King Khalid University Hospital, Riyadh, Saudi Arabia. The patients' clinical characteristics, endoscopic findings, and details of the strictures, treatment, and outcomes were documented. RESULTS: Forty-three children with esophageal strictures were identified (median age, 8.1 years; range, 2-17 years; 23 [53.5%] boys). The median age at presentation was 2 years (range, 1-16 years), and the median follow-up period was 3 years (range, one month-17 years). Tracheoesophageal fistula (n=14, 32.6%), gastroesophageal reflux disease (n=10, 23.3%) and eosinophilic esophagitis (n=8, 18.6%) were the leading causes of esophageal strictures. Forty-three patients underwent 180 dilatation sessions; the median number of dilatation sessions per patient was 3 (range, 1-48), and the median interval between sessions was 8 weeks (range, 1-24 weeks). Among 180 dilatation sessions, 3 events (1.7%) of esophageal perforation were observed. The outcomes varied depending on the primary cause of the stricture; complete response was achieved the best in eosinophilic esophagitis-related strictures (87.5%), followed by anastomotic strictures post tracheoesophageal fistula repair (71.4%) and gastroesophageal reflux disease-related strictures (70%). CONCLUSION: Endoscopic dilatation is a safe and effective intervention in the management of esophageal strictures in children, with minimal complications when conducted by experts.

BACKGROUND/AIM: Although international guidelines in inflammatory bowel disease (IBD) management are currently available, variations in IBD care still exist. The aim of this study was to determine the extent of the variation in IBD care among Saudi pediatric gastroenterologists. MATERIALS AND METHODS: A cross-sectional survey was conducted among all pediatric gastroenterologists who were members of the Saudi Society of Pediatric Gastroenterology, Hepatology, and Nutrition (SASPGHAN) from August 2015 to December 2015. The questionnaire included items on demographic characteristics and utilization of different diagnostic and therapeutic interventions in IBD care. RESULTS: Of the 45 registered pediatric gastroenterologists surveyed, 37 (82%) returned the survey from 20 centers across the country; 75.7% were practicing in tertiary care centers. There was a considerable variation in the use of different diagnostic tests during the initial evaluation of the disease. Utilization of calprotectin assays, magnetic resonance imaging enterography, and bone densitometry seemed to vary the most between physicians practicing at tertiary and secondary care centers. There were statistically significant differences in the prescription of biological therapy between the two groups. CONCLUSIONS: We found a considerable variation in the use of different diagnostic and therapeutic interventions in the management of pediatric IBD patients. Such variations could lead to unintended differences in patient outcomes. Implementation of the available evidence-based guidelines may limit such variations and ultimately could improve the quality of IBD care provided.

Glycogenic hepatopathy is a rare condition that causes significant hepatomegaly and elevated liver enzyme levels in uncontrolled type 1 diabetic patients. It develops due to excessive accumulation of glycogen in the hepatocytes. It is typically reversible with good glycemic control and rarely progresses to mild fibrosis, but not cirrhosis.

BACKGROUND AND AIMS: To systemically evaluate the efficacy of adjuvant vitamin E on the outcomes of nonalcoholic fatty liver disease (NAFLD) and/or nonalcoholic steatohepatitis (NASH) in children. MATERIALS AND METHODS: We searched MEDLINE, PUBMED, EMBASE, the Cochrane Central Register Controlled Trials, and the Cochrane Database of Systematic Reviews over the period between January 1980 and September 2012 for the studies that examined the role of adjuvant vitamin E given at any dose or duration, alone or in combination with other interventions, on the outcome of pediatric NAFLD. The outcomes are alanine aminotransferase (ALT) normalization and histological improvement. RESULTS: Five randomized trials were eligible to be included in our analysis, with a total of 270 participants. There was no statistically significant difference in the effect of adjuvant vitamin E on normalizing serum ALT [risk ratio (RR) =1.18, confidence interval (CI) =0.92-1.53, P = 0.77 for heterogeneity, I2 = 0%]. Sensitivity analysis showed that using higher doses of vitamin E, a longer duration of therapy or adding vitamin C did not change the effect on the measured outcome. Only two studies looked at histological changes as an outcome. We observed substantial heterogeneity between the two studies. CONCLUSIONS: Our meta-analysis did not find a significant effect of adjuvant vitamin E over placebo in normalizing serum ALT. Data on the long-term effect of adjuvant vitamin E on histological improvements in NAFLD patients are still lacking. Larger, well-designed randomized controlled trials (RCTs) in children with histological endpoints are still needed to answer this question.

Infantile gastroesophageal reflux (GER) is a common self-limited, physiological phenomenon. Infantile gastroesophageal reflux becomes pathological (gastroesophageal reflux disease [GERD]) when symptoms become more severe or are associated with complications such as failure to thrive or hematemesis. Though it is a very common condition, there are several misconceptions and myths on GER/GERD diagnosis and management. Inappropriate investigations are frequently requested and unnecessary medications are increasingly prescribed, particularly in infants with symptoms attributed to possible GER/GERD. Several therapeutic interventions are used widely in GERD management, although some evidence is either insufficient or controversial.
