BACKGROUND: Variation in Helicobacter pylori (H. pylori) disease in terms of prevalence and antibiotic resistance prevails globally requiring a need to develop region-specific surveillance. We aimed to assess the influence of immigration factors upon the interpretation of local Singaporean epidemiological trends in antimicrobial susceptibility patterns and therapeutic outcomes in children with culture-positive H. pylori. MATERIALS AND METHODS: We retrospectively analyzed eradication outcomes of children with culture-proven H. pylori infections between 2011 and 2020 at our center, and we also analyzed the antimicrobial susceptibility profiles of the corresponding H. pylori isolates. The cohort was classified into two groups: (1) Native Singaporeans and (2) Non-native Singaporeans (First-/Second-generation immigrants and Non-residents) to correlate with resistance patterns and eradication outcomes. H. pylori culture was done via Kirby-Bauer disk diffusion for the era 2011-2016 and bioMérieux E test for 2016-2020. RESULTS: A total of 70 children (median age 14 [2-17] years) were included in the analysis. 42.9% (30/70) of the cohort displayed some form of antibiotic resistance; clarithromycin resistance was the most prevalent (30.0%), followed by metronidazole (27.5%) and amoxicillin (7.1%). Comparing to natives, non-native Singaporeans were significantly younger at presentation (mean 11.7 vs. 13.7 years, p = 0.043), and a significantly higher proportion of non-natives carried clarithromycin-resistant (51.4% vs. 8.6%, p < 0.001), metronidazole-resistant (47.1% vs. 8.6%, p < 0.001), or multidrug-resistant (resistant to ≥2 drugs) (40.0% vs. 2.9%, p < 0.001] strains. Non-natives were significantly more likely to fail first-line eradication therapy (48.5% failure vs. 23.3%, p = 0.038). The proportion of pan-sensitive H. pylori was significantly lower in first-generation (25.0%, p = 0.001) and second-generation (42.9%, p = 0.018) immigrants compared to natives (82.86%). These conclusions did not vary when the analysis was repeated for each culture method. CONCLUSIONS: An antibiotic susceptibility-based approach should be advocated for all patients but especially so for non-natives, who are at higher risk for antimicrobial resistant strains and poorer eradication outcomes.

Patients with GSD type 1 (von Gierke disease) are initially managed medically to maintain normoglycemia. However, if they do not achieve good metabolic control, LT is then considered. We describe the long-term outcome of 6 children with GSD type 1 who underwent LT. Retrospective chart review of the data of 6 children with GSD type 1 who underwent LT at National University Hospital, Singapore, from May 1998 to October 2018, was performed. The median (IQR) age at diagnosis of the GSD was 1 year (0.92-5.50) and at transplant was 13.88 years (11.46-16.38). All of the patients had elevated liver enzymes, hypercholesterolemia, hypertriglyceridemia, and hyperlactatemia prior to transplant. All of the patients are alive at the time of analysis and follow-up. None of them required a re-transplant. For the three patients who had hypoglycemia pretransplant, there was no recurrence post-transplant. All of the patients had normalization of liver enzymes by 1 year post-transplant. Long-term outcome of patients with GSD who underwent LT has been positive with improvement in metabolic control for most patients. We report the unusual finding of two siblings with persistent hyperuricemia post-transplant requiring allopurinol.

This paper proposes recommendations for probiotics in pediatric gastrointestinal diseases in the Asia-Pacific region. Evidence-based recommendations and randomized controlled trials in the region are included. Cultural aspects, health management issues and economic factors were also considered. Final recommendations were approved by utilizing a modified Delphi process and applying the Likert scale in an electronic voting process. Bacillus clausii was recommended as an adjunct treatment with oral rehydration solution for acute viral diarrhea. B. clausii may also be considered for prevention of antibiotic-associated diarrhea, Clostridium difficile-induced diarrhea, and as adjunct treatment of Helicobacter pylori. There is insufficient evidence for recommendations in other conditions. Despite a diversity of epidemiological, socioeconomical and health system conditions, similar recommendations currently apply to most Asia-Pacific countries. Ideally, these need to be validated with local randomized-controlled trials.
RESUMEN
BACKGROUND: Current knowledge on the clinical features and natural history of childhood primary sclerosing cholangitis - inflammatory bowel disease in Asia is limited. We described the presenting features and natural history of primary sclerosing cholangitis-inflammatory bowel disease seen in a cohort of Southeast Asian children. METHODS: We conducted a retrospective review of childhood primary sclerosing cholangitis-inflammatory bowel disease from three tertiary centers in Singapore and Malaysia. RESULTS: Of 24 patients (boys, 58%; median age at diagnosis: 6.3 years) with primary sclerosing cholangitis-inflammatory bowel disease (ulcerative colitis, n = 21; Crohn's disease, n = 1; undifferentiated, n = 2), 63% (n = 15) were diagnosed during follow-up for colitis, and 21% (n = 5) presented with acute or chronic hepatitis, 17% (n = 4) presented simultaneously. Disease phenotype of liver involvement showed 79% had sclerosing cholangitis-autoimmune hepatitis overlap, 54% large duct disease, and 46% small duct disease. All patients received immunosuppression therapy. At final review after a median [±S.D.] duration follow-up of 4.7 [±3.8] years, 12.5% patients had normal liver enzymes, 75% persistent disease, and 12.5% liver failure. The proportion of patients with liver cirrhosis increased from 13% at diagnosis to 29%; 21% had portal hypertension, and 17% had liver dysfunction. One patient required liver transplant. Transplant-free survival was 95%. For colitis, 95% had pancolitis, 27% rectal sparing, and 11% backwash ileitis at initial presentation. At final review, 67% patients had quiescent bowel disease with immunosuppression. One patient who had UC with pancolitis which was diagnosed at 3 years old developed colorectal cancer at 22 years of age. All patients survived. CONCLUSIONS: Liver disease in primary sclerosing cholangitis-inflammatory bowel disease in Asian children has variable severity. With immunosuppression, two-thirds of patients have quiescent bowel disease but the majority have persistent cholangitis and progressive liver disease.

PURPOSE: The understanding of the HRQOL issues for parent donors of children who underwent LDLT is lacking. We evaluated the HRQOL of donor and non-donor parents, described their subjective experiences and identified factors associated with lower HRQOL post-donation. METHODS: This is a cross-sectional study of parent donors whose children underwent LDLT, using SF-36v2 Health Survey to measure HRQOL, and a self-developed questionnaire to evaluate their subjective experiences. RESULTS: Of 32 pairs of donor and non-donor parents, 27 donor and 19 non-donor parents responded. The data of respondents were analyzed. Both donor and non-donor parents' SF-36v2 norm-based scores were average or above average as compared to the Singapore population. Donors who made lifestyle changes post-donation (adopting a healthy balanced diet, regular physical activity, quitting smoking, and moderate alcohol intake) were associated with lower GH (P = 0.009) and PF (P = 0.002) scores. Donors who took more than 3 months for full recovery had lower RP (P = 0.022) and BP scores (P = 0.038). On multivariate analysis, recipient complication of Clavien grade 3 or 4 was associated with increased RP score by 8.71 points (95% CI: 1.74-15.68), after adjusting for time taken for full recovery. Majority (88.8%) had self-reported recovery time under 6 months and returned to work within 3 months (74.0%). CONCLUSIONS: Donors with factors potentially associated with lower HRQOL may need more support to ensure better HRQOL outcomes post-donation.

With the increase in long-term survival of post-transplant children, there is a paradigm shift in the emphasis of post-transplant care. We describe de novo cardiovascular abnormalities, which occurred in otherwise asymptomatic paediatric liver transplant recipients, who received liver allografts between 1991 and 2014 at the National University Hospital, Singapore, detected during routine post-transplant monitoring. A total of 96 paediatric liver transplants were performed in 90 children. After transplant, 7/90 (7.8%) recipients were identified with new-onset aortopathy. Glycogen storage disease type I (42.9% versus 2.4%; p<0.001) and recipient Epstein-Barr virus seropositivity (85.7 versus 31.0%, p=0.004) were significant risk factors for aortopathy on univariate analysis. On multivariate analysis, only glycogen storage disease type I remained as the significant risk factor (odds ratio 51.3 [95% confidence intervals: 1.1-2498.1, p=0.047]). Liver transplant is a double-edged sword that reverses certain cardiopulmonary complications of end-stage liver disease but may induce de novo structural cardiac injury in the form of aortic dilation.

PURPOSE: Lactose intolerance (LI) is perceived to be frequent in Asia and has been reported to have considerable impact on dietary intake, nutritional status and the quality of life. We aimed to gather information from healthcare professionals on the perceived incidence, diagnosis and management of LI in 1 to 5 year old children in Southeast Asia. METHODS: An anonymous electronic survey was sent randomly among healthcare professionals registered in the database of the pediatric societies in Thailand, Indonesia, and Singapore between June and October 2016. RESULTS: In total, 259 health care professionals responded of which 45.5% (n=118) were from Thailand, 37.4% (n=97) from Indonesia and 16.9% (n=44) from Singapore. Of the participants who responded (n=248), primary LI prevalence among children 1 to 3 years of age was estimated to be less than 5% by 56.8%. However, about 18.9% (n=47) answered they did not know/unsure. Regarding secondary LI, 61.6% of respondents (n=153) estimated the prevalence to be less than 15%. But again, 10.8% (n=27) answered they did not know or unsure. Rotavirus gastroenteritis was ranked as the top cause for secondary LI. There was considerable heterogeneity in the diagnostic methods used. The majority of respondents (75%) recommended lactose-free milk to manage primary and secondary LI. CONCLUSION: More education/training of pediatricians on this topic and further epidemiological studies using a more systematic approach are required.
RESUMEN
The concept of consuming microorganisms in the treatment of a medical condition and in health maintenance has gained much attraction, giving rise to an abundance of medical claims and of health supplements. This study identified relevant clinical questions on the therapeutic use of probiotics and reviewed the literature in irritable bowel syndrome, inflammatory bowel disease, impaired intestinal immunity, liver disease, intestinal infections, and common childhood digestive disorders. Statements were developed to address these clinical questions. A panel of experienced clinicians was tasked to critically evaluate and debate the available data. Both consensus and contentious statements are presented to provide to clinicians a perspective on the potential of probiotics and importantly their limitations.

BACKGROUND: The use of complementary and alternative medicine (CAM) has been associated with adverse effects and self-imposed dietary restrictions. The prevalence of its use in Asian children with inflammatory bowel disease (IBD) is unknown. We aimed to determine the prevalence, types, and factors associated with the use of CAM among children with IBD from Singapore and Malaysia, and to ascertain if dietary restriction was prevalent in patients who used CAM. METHODS: A cross-sectional study was conducted in which parents of children with IBD attending two tertiary pediatric IBD referral centres in Singapore and Malaysia were interviewed. Data about demographics, conventional treatment, complementary therapies and dietary patterns were collected in a questionnaire. RESULTS: Of 64 children with IBD interviewed, 83% (n = 53) reported the use of CAM (Singapore [90%] vs. Malaysia [76%]; p = 0.152). The median number of CAM agents used was two (range 1-10). The three most common types of CAM used were probiotics (64%), vitamin and mineral supplements (55%), and food-based therapies (36%). Among individual CAM categories, the use of food-based therapies was correlated significantly with nationality (r = 0.497, p < 0.001), history of weight loss due to IBD (r = 0.340, p = 0.013) and avoidance of certain foods to prevent a relapse (r = 0.289, p = 0.036). Parents who rated their child's disease activity as more severe were less likely to use CAM (r = -0.257, p = 0.041). Fifty-nine percent of CAM users reported physician awareness of their CAM use. The overall self-perceived efficacy of CAM in improving IBD symptoms was 34%. Of the dietary patterns explored, only intake of dairy products was associated with CAM use (r = 0.306, p = 0.019). CONCLUSION: Use of CAM is prevalent in children with IBD in Malaysia and Singapore. Further studies to elucidate reasons influencing CAM use, dietary patterns and efficacy of commonly used CAM would be required.

BACKGROUND: We aimed to evaluate clinical characteristics, risk factors, and disease outcomes for liver transplant recipients (LTR) with post-transplant lymphoproliferative disease (PTLD) at our center. METHODS: Retrospective review of data of all pediatric LTR (1991-2015) was conducted. RESULTS: The overall incidence of PTLD was 16.4% (18/110), the majority (13/18) were early lesions, while 3/18 were polymorphic/monomorphic PTLD. The risk factors significant on univariate analysis were as follows: mean age (years) at transplant (1.66 vs 4.76, P = .006); age <2 years at transplant (odds ratio [OR] 3.53 [95% confidence interval [CI]: 1.16-10.73], P = .026); cytomegalovirus (CMV) primary infection (OR 11.39 [95% CI: 3.44-37.7], P < .001); recipient CMV seronegativity (OR 7.50 [95% CI: 2.02-27.78], P = .003); presence of CMV end-organ disease (OR 4.00 [95% CI: 1.22-13.16], P = .022); Chinese ethnicity; and higher mean duration of intravenous ganciclovir prophylaxis. In multivariate analysis, CMV primary infection (OR 5.22 [95% CI: 1.25-21.87], P = .024), CMV seronegativity (OR 5.91 [95% CI: 1.13-30.90, P = .035]), and having acute cellular rejections (ACR) prior to PTLD (OR 5.53 [95% CI: 1.43-21.48, P = .013]) were significant risk factors for PTLD, with the latter two factors having a synergistic effect in increasing PTLD risk in a stratified analysis. The final multivariate model in predicting the risk of PTLD, utilizing CMV primary infection, recipient CMV seronegativity, and ACR before PTLD as predictive variables, was statistically significant (likelihood ratio chi square statistic = 25.18, P < .0001 with df = 3). CONCLUSIONS: We report a unique clinicopathologic and risk factor profile in our cohort-early lesion PTLD accounts for the majority and the incidence of monomorphic PTLD remains low. In addition, we show a synergism between CMV naivety and ACR on PTLD risk, a higher prevalence of gastrointestinal manifestations, and a lack of significant association with Epstein-Barr virus seronegativity.

The published paediatric experience with endoscopic retrograde cholangio-pancreatography (ERCP) in the diagnosis and management of biliary complications following liver transplantation (LT) is limited. We describe our experience with ERCP in the management of children following LT who presented with biliary complications, over a 20-year period (1995-2014). The retrospectively reviewed data are summarized descriptively. Of 94 children (47 boys) who received 102 liver transplants at our centre, seven children (five boys, two girls) underwent ERCP after liver transplantation. In total, 25 ERCP procedures were carried out in these patients. The median age at liver transplantation was 10.7 (3.9-16.2) years. The median interval between LT and the first ERCP was 28 days (12 days-6.8 years). All patients were on standard calcineurin-inhibitor-based immunosuppression regimens. Six of the seven patients underwent ERCP on more than one occasion [median number of ERCP sessions per patient- 4, (1-6)]. Seventeen procedures were carried out under conscious sedation, remaining eight under general anaesthesia. Sedation was achieved employing a standard regimen (Midazolam 5 mg with Pethidine 50 mg) and occasionally Fentanyl. ERCP is an effective and safe intervention from both diagnostic and therapeutic point of view, in the management of post-LT biliary complications in children.

OBJECTIVES: To estimate the cost of functional gastrointestinal disorders (FGIDs) and related signs and symptoms in infants to the third party payer and to parents. STUDY DESIGN: To estimate the cost of illness (COI) of infant FGIDs, a two-stage process was applied: a systematic literature review and a COI calculation. As no pertinent papers were found in the systematic literature review, a 'de novo' analysis was performed. For the latter, the potential costs for the third party payer (the National Health Service (NHS) in England) and for parents/carers for the treatment of FGIDs in infants were calculated, by using publicly available data. In constructing the calculation, estimates and assumptions (where necessary) were chosen to provide a lower bound (minimum) of the potential overall cost. In doing so, the interpretation of the calculation is that the true COI can be no lower than that estimated. RESULTS: Our calculation estimated that the total costs of treating FGIDs in infants in England were at least £72.3 million per year in 2014/2015 of which £49.1 million was NHS expenditure on prescriptions, community care and hospital treatment. Parents incurred £23.2 million in costs through purchase of over the counter remedies. CONCLUSIONS: The total cost presented here is likely to be a significant underestimate as only lower bound estimates were used where applicable, and for example, costs of alternative therapies, inpatient treatments or diagnostic tests, and time off work by parents could not be adequately estimated and were omitted from the calculation. The number and kind of prescribed products and products sold over the counter to treat FGIDs suggest that there are gaps between treatment guidelines, which emphasise parental reassurance and nutritional advice, and their implementation.

INTRODUCTION: We aimed to determine the prevalence and clinical manifestations of eosinophilic oesophagitis (EoE) in children who presented to a tertiary care hospital in Singapore. METHODS: We conducted a retrospective review of all oesophageal biopsies taken during oesophagogastroduodenoscopy (OGD) from March 2010 to December 2011. The patients' demographics and clinical characteristics were collected. Biopsies were reviewed by a single pathologist who was blinded to the original reports, using the current consensus criteria for the histological diagnosis of EoE. RESULTS: Of the 88 children who had biopsies during OGD, 4 (4.5%) children (three boys, one girl; three Chinese, one Caucasian) were diagnosed with EoE. Their median age was 9.5 (range 4.0-12.0) years. The main clinical presentations were abdominal pain (in the three older children) and vomiting (in the youngest child). Three children had a history of atopy. Three children were diagnosed with EoE in the original histology reports, while one was diagnosed after the second review following histology demonstrating > 15 eosinophil granulocytes per high power field and microabscess formation. Endoscopy findings revealed oesophagitis in two children, one of whom was already on acid suppression therapy. Although three children were started on acid suppression therapy, they continued to be symptomatic. One child was also treated with swallowed fluticasone and two with food allergen avoidance, resulting in symptom improvement. CONCLUSION: Although EoE is uncommon in Singapore, greater awareness is needed among family physicians and general paediatricians. Paediatric gastroenterologists should alert pathologists when sending biopsy specimens that are suspicious for EoE.

INTRODUCTION: This was the first study conducted to evaluate the efficacy of 2 oral doses of the human rotavirus vaccine, RIX4414 in Singaporean infants during the first 3 years of life. MATERIALS AND METHODS: Healthy infants, 11 to 17 weeks of age were enrolled in this randomised (1:1), double-blinded, placebo-controlled study to receive 2 oral doses of RIX4414 vaccine/placebo following a 0-, 1-month schedule. Vaccine efficacy against severe rotavirus (RV) gastroenteritis (Vesikari score ≥11) caused by wild-type RV strains from a period starting from 2 weeks post-Dose 2 until 2 and 3 years of age was calculated with 95% confidence interval (CI). Immunogenicity and safety of the vaccine were also assessed. RESULTS: Of 6542 infants enrolled, 6466 were included in the efficacy analysis and a subset of 100 infants was included in the immunogenicity analysis. Fewer severe RV gastroenteritis episodes were reported in the RIX4414 group when compared to placebo at both 2 and 3 year follow-up periods. Vaccine efficacy against severe RV gastroenteritis at the respective time points were 93.8% (95% CI, 59.9 to 99.9) and 95.2% (95% CI, 70.5 to 99.9). One to 2 months post-Dose 2 of RIX4414, 97.5% (95% CI, 86.8 to 99.9) of infants seroconverted for anti-RV IgA antibodies. The number of serious adverse events recorded from Dose 1 until 3 years of age was similar in both groups. CONCLUSION: Two oral doses of RIX4414 vaccine was immunogenic and provided high level of protection against severe RV gastroenteritis in Singaporean children, during the first 3 years of life when the disease burden is highest.

OBJECTIVES: Routine oesophago-gastro-duodenoscopy (OGD) pre-liver transplantation (LT) for evaluation and management of gastrointestinal (GI) pathology, in particular GI varices secondary to portal hypertension, is common practice in adult LT programmes. There is no universal consensus for this practice in children. We report our endoscopic experience in children with end-stage liver disease (ESLD) pre-LT. METHODS: Retrospective audit of LT database and review of OGD findings of patients who had undergone endoscopy preceding LT. RESULTS: Of 69 patients with ESLD, 50 (72.4%) had pre-LT OGD, 37 of which were done electively, whereas the remaining 13 were event driven. Forty-eight (96%) patients who underwent OGD had abnormalities, in which 38 (76%) patients had varices and 23 (46%) had portal hypertensive gastropathy. Eleven (22%) patients required therapeutic intervention at initial OGD either with endoscopic variceal band ligation or endoscopic sclerotherapy. Compared with the group who underwent elective OGDs, the group who had event-driven OGDs had a significantly higher requirement for endoscopic intervention (Pâ<â0.0001), occurrence of rebleeding (Pâ<â0.029) and requirement for repeat OGDs (Pâ=â0.014). There was no significant difference in terms of patient (Pâ=â0.2746) or graft survival (Pâ=â0.3192) between the 2 groups. CONCLUSIONS: The role of pre-LT OGDs in patients with ESLD associated with portal hypertension is possibly limited to control of bleeding during episodes of GI bleed, where the aim would be to stabilize the patient until eventual LT. Multicentre prospective studies are required to provide more evidence on the use of routine endoscopy for pre-LT assessment in children.

Cyclical vomiting syndrome (CVS) is a functional, debilitating disorder of childhood frequently leading to hospitalization. Affected children usually experience a stereotypical pattern of vomiting though it may vary between different individuals. The vomiting is intense often bilious, and accompanied by disabling nausea. Identifiable precipitating factors for CVS include psychosocial stressors, infections, lack of sleep and occasionally even food triggers. Often, it may be difficult to distinguish episodes of CVS from other causes of acute abdomen and altered consciousness. Thus, the diagnosis of CVS remains largely one of exclusion. Investigations routinely done during the work-up of a child with suspected CVS include both blood and imaging modalities. Plasma lactate, ammonia, amino acid and acylcarnitine profiles as well as urine organic acid profile are indicated to exclude inborn errors of metabolism. The treatment remains challenging and targeted at prevention or shortening of the attacks and can be considered as abortive, supportive and prophylactic. Use of non-pharmacological therapy is also part of the management of CVS. The prognosis of CVS is variable. More insight into the pathogenesis of this disorder as well as role of non-pharmacological therapy is needed.
RESUMEN
The Early Nutrition Academy supported a systematic review of human studies on the roles of pre- and postnatal long-chain polyunsaturated fatty acids (LC-PUFA) published from 2008 to 2013 and an expert workshop that reviewed the information and developed recommendations, considering particularly Asian populations. An increased supply of n-3 LC-PUFA during pregnancy reduces the risk of preterm birth before 34 weeks of gestation. Pregnant women should achieve an additional supply ≥200 mg docosahexaenic acid (DHA)/day, usually achieving a total intake ≥300 mg DHA/day. Higher intakes (600-800 mg DHA/day) may provide greater protection against early preterm birth. Some studies indicate beneficial effects of pre- and postnatal DHA supply on child neurodevelopment and allergy risk. Breast-feeding is the best choice for infants. Breast-feeding women should get ≥200 mg DHA/day to achieve a human milk DHA content of â¼0.3% fatty acids. Infant formula for term infants should contain DHA and arachidonic acid (AA) to provide 100 mg DHA/day and 140 mg AA/day. A supply of 100 mg DHA/day should continue during the second half of infancy. We do not provide quantitative advice on AA levels in follow-on formula fed after the introduction of complimentary feeding due to a lack of sufficient data and considerable variation in the AA amounts provided by complimentary foods. Reasonable intakes for very-low-birth weight infants are 18-60 mg/kg/day DHA and 18-45 mg/kg/day AA, while higher intakes (55-60 mg/kg/day DHA, â¼1% fatty acids; 35-45 mg/kg/day AA, â¼0.6-0.75%) appear preferable. Research on the requirements and effects of LC-PUFA during pregnancy, lactation, and early childhood should continue. © 2014 S. Karger AG, Basel.
