RESUMEN
BACKGROUND: Hypoalbuminemia after liver transplantation (LT) is associated with acute kidney injury (AKI) and poor outcomes in adult LT recipients. This study was performed to examine the association between the postoperative serum albumin level and early postoperative outcomes of LT in children. METHODS: This single-center retrospective review involved pediatric LT recipients (0-18 years old) treated from January 2013 to June 2020. All patients were admitted to PICU and received standard post-LT care protocol. We divided patients into low (< 30 g/L) and normal (> 30 g/L) groups based on postoperative albumin day 1 to 3. RESULTS: Among 108 LT recipients, most had biliary atresia. The median age at the time of LT was 1.8 years [interquartile range (IQR), 1.5-5.7]. There were 18 patients in low albumin group [median albumin level, 27.9 g/L (IQR, 25.8-29.6) and 90 patients in normal albumin group [median albumin level, 34.5 g/L (IQR, 32.4-36.9). The low albumin group had significantly higher incidence of AKI, occurring in 20% of patients with a median onset of 2.5 days following LT (IQR, 1-5). Postoperative hypoalbuminemia (OR, 4.94; 95% CI, 1.32-18.47; p = 0.01) and a longer operative time (OR, 1.37; 95% CI, 1.01-1.47; p = 0.02) were independent risk factors for AKI by multivariable analysis. No significant differences between the two groups were found in other early postoperative outcomes. CONCLUSION: Postoperative hypoalbuminemia was associated with early postoperative AKI following LT in children but not with other worsening outcomes.

Purpose: To evaluate the prevalence of vertebral fracture (VF) in children with chronic liver disease (CLD) with and without liver transplantation (LT) and to determine the associated factors. Methods: A cross-sectional study was conducted. Patients aged 3-21 years with CLD both before and after LT were enrolled in the study. Lateral thoracolumbar spine radiographs were obtained and assessed for VF using Mäkitie's method. Clinical and biochemical data were collected. Results: We enrolled 147 patients (80 females; median age 8.8 years [interquartile range 6.0-11.8]; 110 [74.8%] in the LT group and 37 [25.2%] in the non-LT group). VF was identified in 21 patients (14.3%): 17/110 (15.5%) in the LT group and 4/37 (10.8%) in the non-LT group (p=0.54). Back pain was noted in only three patients with VF. In the univariate analysis, a height z-score below -2.0 (p=0.010), pre-LT hepatopulmonary syndrome (p=0.014), elevated serum direct and total bilirubin levels (p=0.037 and p=0.049, respectively), and vitamin D deficiency at 1-year post-LT (p=0.048) were associated with VF in the LT group. In multivariate analysis, height z-score below -2.0 was the only significant associated factor (odds ratio, 5.94; 95% confidence interval, 1.49-23.76; p=0.012) for VF. All VFs in the non-LT group were reported in males. Conclusion: In children with CLD, VF is common before and after LT. Most patients with VF are asymptomatic. Screening for VF should be considered in patients with a height z-score below -2.0 after LT.
RESUMEN
BACKGROUND: Despite the rising incidence of pediatric inflammatory bowel disease (PIBD) globally, multicenter collaborative studies of PIBD children among developing countries remain sparse. We therefore aimed to define the initial presentation and short-term outcomes of Thai children with PIBD from a multicenter registry. METHODS: Four teaching hospitals participated in this study. A diagnosis of PIBD requires gastrointestinal endoscopy and histopathology in children aged < 19 years. Besides demographics, we collected clinical information and treatment with the data at 1-year follow up. RESULTS: We included 35 Crohn's disease (CD), one IBD-unclassified, and 36 ulcerative colitis (UC) children (total n = 72 with 60.6% males). The mean age at diagnosis was 7.9 years (SD 4.1) with 38% being very early onset IBD (VEO-IBD). When compared with UC, the CD children were more likely to exhibit fever (42.3 vs. 13.9%), weight loss/failure to thrive (68.6 vs. 33.3%), and hypoalbuminemia (62.9 vs. 36.1%) but less likely to have bloody stools (51.4 vs. 91.7%) (all P < 0.05). No significant differences in demographics, clinical data and medications used with regards to VEO-IBD status. At 1 year after diagnosis (n = 62), 30.7% failed to enter clinical remission and 43.7% remained on systemic corticosteroids. Diarrhea (OR 9.32) and weight issues (OR 4.92) at presentation were independent predictors of failure to enter clinical remission; and females (OR 3.08) and CD (vs. UC) (OR 3.03) were predictors of corticosteroids use at 1-year follow-up. CONCLUSIONS: A high proportion of VEOIBD is noted, and CD was more likely to present with significant inflammatory burden. Diarrhea and weight issues at presentation were independent predictors of failure to enter clinical remission; and females and CD (vs. UC) were predictors of corticosteroids use at 1-year follow-up.

Clinicians are faced with evaluating real and alleged reactions to foods that may be allergic or nonallergic. Pathogenesis, diagnosis, and treatment of various non-IgE-mediated diseases are discussed in this review. These food-related conditions range from mild to severe. Referral for an allergy workup may be pursued despite the lack of IgE-mediated symptoms. Diagnostic testing is available for defined non-IgE-mediated food diseases that are either immunologic or nonimmunologic. These include celiac disease and related disorders, carbohydrate maldigestion, pancreatic insufficiency, and histamine intolerance. In contrast, there is a paucity of definitive studies to prove food intolerance diseases. There are no definitive diagnostic criteria or testing for nonceliac gluten sensitivity. Functional gastrointestinal disorders, such as irritable bowel syndrome, are better stratified diagnostically but still lack reliable testing. Both nonceliac gluten sensitivity and irritable bowel syndrome are linked to dietary triggers including fermentable oligosaccharides, disaccharides, monosaccharides, and polyols. Therefore, dietary alteration alone may be diagnostic and therapeutic when all other conditions are ruled out. These conditions are important considerations when evaluating a patient with history of a food reaction. There is little evidence that foods are causative in other ailments such as acne, migraines, and nasal congestion and hypersecretion.

BACKGROUNDS: To compare factor(s) contributing to aetiology, management and clinical outcome(s) of paediatric patients acquiring acute pancreatitis (AP) at two major university paediatric surgical centres in Liverpool and Bangkok. METHODS: All patients (<18 years) with an index diagnosis of AP (ICD 10 coding) during 2006-2016 were studied. RESULTS: 121 patients included n = 79 (65.3%) in Thailand versus n = 42 (34.7%) in the UK centre with no difference(s) in age at diagnosis at 10.4 ± 4.5 and 11.7 ± 6 years. (P = 0.12). Major AP aetiology(s) in Thailand were medications (39.2%) and choledochal cysts (8.9%). In the UK-gallstone disease (21.4%), and medications (16.7%) were leading factors (P < 0.01). Ultrasonography was deployed more frequently in the UK versus Thai centre (74.3% vs. 49.1%; P < 0.01). Pancreatitis was confirmed by imaging in 67.9% (Thai) and 62.9% (UK) patients (P = 0.47). Most patients at both centres had a mild-grade pancreatitis illness (95% Thai vs. 90.5% UK; P = 0.28) while 12.7% of Thai and 19% of UK children developed pancreatitis-related complication (P = 0.37). Overall mortality rate (%) was significantly higher in the Thai versus UK centre (27.8% vs. 9.5%; P = 0.02). CONCLUSIONS: Aetiology of acute pancreatitis appears to vary between UK and Thailand children. Timely early diagnosis and healthcare pathways may be driven by local patient-related factor(s). The higher mortality (%) observed in Thailand versus UK in this comparative study was linked to underlying co-existent chronic medical condition(s) in vulnerable patient cohorts.

Cytomegalovirus (CMV) infection is a major opportunistic infection after liver transplantation (LT) that necessitates monitoring. Because of the lack of studies in children, we aimed to investigate CMV-specific T cell immune reconstitution among pediatric LT recipients. The recipients were monitored for CMV infection and CMV-specific T cells from the start of immunosuppressive therapy until 48 weeks after LT. Clinically significant CMV viremia (csCMV) requiring preemptive therapy was defined as a CMV load of >2000 IU/mL. Peripheral blood CMV-specific T cells were analyzed by flow cytometry based on IFNγ secretion upon stimulation with CMV antigens including immediate early protein 1 (IE1) Ag, phosphoprotein 65 (pp65) Ag, and whole CMV lysate (wCMV). Of the 41 patients who underwent LT, 20 (48.8%) had csCMV. Most (17/20 patients) were asymptomatic and characterized as experiencing CMV reactivation. The onset of csCMV occurred approximately 7 weeks after LT (interquartile range: 4-12.9); csCMV rarely recurred after preemptive therapy. Lower pp65-specific CD8+ T cell response was associated with the occurrence of csCMV (p = 0.01) and correlated with increased viral load at the time of csCMV diagnosis (ρ = -0.553, p = 0.02). Moreover, those with csCMV had lower percentages of IE1-specific CD4+ and wCMV-reactive CD4+ T cells at 12 weeks after LT (p = 0.03 and p = 0.01, respectively). Despite intense immunosuppressive therapy, CMV-specific T cell immune reconstitution occurred in pediatric patients post-LT, which could confer protection against CMV reactivation.

BACKGROUND: Many children respond to medical treatment for gastroesophageal reflux disease (GERD). However, some may require invasive intervention for refractory disease. Due to the lack of prognostic tools in children, this study aimed to develop a predictive model for refractory GERD. METHODS: A retrospective review was performed in children with symptoms of GERD at a university hospital. Refractory GERD was defined as an unresponsive disease after optimal treatment with medication for >8 weeks. The predictive model was constructed based on clinical features and 24-h multichannel intraluminal impedance-pH (MII-pH) monitoring results. RESULTS: A total of 205 children were included with a median (IQR) age of 0.6 (0.3, 2.0) years. Over half of the patients (59.5%) had motor disabilities. Forty-four children (21.5%) were diagnosed with refractory GERD and subsequently underwent fundoplication. Multivariable analysis suggested that the refractory disease was associated with motor disabilities (OR: 5.35; 95% CI: 2.06-13.91), recurrent aspiration pneumonia (OR: 2.78; 95% CI: 1.24-6.26), prematurity with an onset of GERD at a post-conceptual age <40 weeks (OR: 6.76; 95% CI: 1.96-23.33), and abnormal total reflux episodes according to age (OR: 2.78; 95% CI: 1.24-6.19), but not the acid exposure time or symptom association analysis. The predictive model for refractory GERD based on associated factors revealed an area under the ROC curve of 76.8% (95% CI: 69.2%-84.3%) with a sensitivity of 77.3% and a specificity of 64% when applying a cutoff score of ≥2.5. CONCLUSIONS: The predictive model, using clinical features and MII-pH, may be an additional tool to predict refractory GERD in young children.

To determine the clinical manifestations and outcomes of the coronavirus disease 2019 (COVID-19) in children who underwent liver transplantation (LT). A retrospective study was conducted at a transplant center in Thailand to include LT recipients aged < 18 years who had been infected with COVID-19. Out of a total of 54 children, there were 31 probable cases (57.4%) diagnosed using an antigen test kit and 23 confirmed cases (42.6%) diagnosed using polymerase chain reaction (14 children) or severe acute respiratory syndrome coronavirus 2 antigen (9 children). Approximately half of the children (25, 46.3%) received the BNT162b2 vaccine before the infection, with 3 and 2 doses in 5 and 18 children, respectively. While some had COVID-19 during the delta pandemic, most (46 children, 85.2%) were infected during the omicron pandemic, of which manifestations included fever (67.4%), cough (50%), and rhinorrhea (47.8%), and symptoms lasted approximately 3 days. None had severe diseases. All patients with mild-to-moderate disease were advised to continue the same immunosuppressive therapy as before the infection. Compared to unvaccinated children or children with one dose of the vaccine, fever was less common in those who received ≥ 2 doses (OR: 0.08; 95%CI: 0.01-0.57, adjusted for age and immunosuppressive types). Favipiravir was prescribed in most patients (90.7%). Only a few children had long COVID-19 or abnormal liver function tests lasting > 1 month (4 children, 7.4%, both). Pediatric LT recipients with COVID-19 during the delta and omicron variant pandemic reported mild symptoms despite undergoing immunosuppressive therapy.

Infectious diarrhea is a common problem among post-transplant recipients. Compared to conventional tests, polymerase chain reaction (PCR)-based stool tests have been shown to improve diagnostic yield but the aforementioned data in children remain limited. Our aims were to assess the detection rate of PCR-based tests in post-transplant children and compare with the conventional tests; and to investigate how these stool tests help in managing these children. We enrolled children aged 1 to 19 years who underwent solid organ transplantation or hematopoietic stem cell transplantation that remained on immunosuppressive agents and developed diarrhea ≥ 24 hours between January 2015 and February 2023. Besides stool tests, data on demographics, clinical characteristics and management were collected. We analyzed 68 patients and 92 episodes of diarrhea with PCR-based tests. PCR-based tests provided a detection rate of 41.8% versus 16.5% for the conventional tests. While conventional tests may detect a higher proportion of Clostridiodes difficile infection, PCR-based tests showed greater yields in detecting Salmonella spp. and viruses especially norovirus. PCR-based tests had an impact in management among 22/38 (58%) diarrheal episodes especially with Campylobacter jejuni and C difficile; and among 16 episodes that positive PCR-based tests had a minimal impact, the most common reason was due to the need for continuation of antimicrobial agents for concomitant site-specific infection (69%). Among transplanted children presenting with diarrhea, PCR-based tests provide a higher yield when compared with the conventional tests. The PCR-based stool tests may also further guide clinicians for providing proper antimicrobial agents.

BACKGROUND: Timing for liver transplantation (LT) in biliary atresia (BA) children with end-stage liver disease (ESLD) is associated with all-cause mortality. The cut-off value of pediatric end-stage liver disease (PELD) score for LT consideration varies across institutions. We aimed to determine the cost-effectiveness of LT to prevent death among BA children registered on the waiting list with different severities of ESLD. METHODS: Subjects were BA children aged < 12 years at a transplant center between 2010 and 2021. A decision tree was developed for cost-effectiveness analysis from a hospital perspective to compare all-cause death between patients initially registered with a low PELD score (< 15) and a high PELD score (≥ 15). Each patient's direct medical cost was retrieved from the beginning of registration until 5 years after LT, adjusted with an inflation rate to 2022 Thai Baht (THB). RESULTS: Among 176 children, 138 (78.4%) were initially registered with the high PELD score. The cost and mortality rate of the low PELD score group (THB1,413,424 or USD41,904 per patient and 31.6% mortality) were less than the high PELD score group (THB1,781,180 or USD52,807 per patient and 47.9% mortality), demonstrating the incremental cost-effectiveness ratio (ICER) of THB2,259,717 or USD66,994 per death prevented. The cost of early post-operative admission had the highest effect on the ICER. Considering the break-even analysis, cost among children initially registered at the low PELD score was also less expensive over time. CONCLUSIONS: Registration for LT at PELD score < 15 was more cost-effective to prevent death among BA children with ESLD.

BACKGROUND & AIMS: Studies have determined that people with genetically defined lactase non-persistence have lower dairy intake that may lead to an increase risk of various non-communicable diseases. Furthermore, lactase non-persistence itself has been associated with insulin resistance. However, data on lactase non-persistence status and dairy intake in developing countries are sparse. We therefore aimed to define 1) the prevalence of lactase non-persistence among individuals with diabetes and non-diabetes in Thai population and 2) the links between lactase non-persistence, milk consumption, and risk of diabetes mellitus. METHODS: We conducted a case-control study from participants of the National Health Examination Survey. DNA was isolated from the blood for LCT -13910C>T (rs4988235) polymorphism and processed using the Bio-rad c1000 touch thermal cycler and MALDI-TOF Mass Spectrometry MassARRAY Typer v4.0 (Agena Bioscience, San Diego, CA, USA) at the Center for Medical Genomics, Faculty of Medicine Ramathibodi Hospital. Cases were participants with previously diagnosed diabetes mellitus or fasting plasma glucose ≥126 mg/dL (n = 1,756) vs. the controls (n = 2,380). RESULTS: We included 4,136 participants, 62% female, and 98.8% were > 30 years old. Homozygous CC genotype (i.e., lactase non-persistence) was noted in 98.6% and only 1.4% carried heterozygous CT. Most (76%) consumed milk <1 portion/month. Participants with either CC or CT genotype had comparable milk consumption and the risk of diabetes mellitus. Males, older adults, and lower education had a lower chance of consuming milk at least one portion per month. Besides various baseline variables, we found that higher milk consumption was associated with a lower DM risk (P = .01). CONCLUSION: The prevalence of lactase non-persistence in Thai population is very high. A significant difference in milk consumption frequency in relation to the lactase non-persistence status was not found. However, higher milk consumption is associated with a lower risk of diabetes mellitus.

Cow's milk protein allergy (CMPA) is children's most common food allergy. Therapeutic infant formulas for CMPA lead to symptom-free and potentially benefit early tolerance induction and reducing the allergic march in non-breastfed babies. This study assessed the cost-effectiveness of CMPA management with different therapeutic infant formulas in Thailand, which may reflect situations in developing countries throughout Asia. An analytic decision model was developed to simulate the occurrence of eczema, urticaria, asthma, rhinoconjunctivitis, or being symptom-free in infants with CMPA over 36 months. Extensively hydrolyzed casein formula with added probiotic Lacticaseibacillus rhamnosus (previously Lactobacillus rhamnosus) strain GG (EHCF+LGG), extensively hydrolyzed whey formula (EHWF), soy protein-based formula (SPF), and amino acid formula (AAF) were compared from the healthcare payer perspective. The results from a prospective cohort study were used for comparative effectiveness measures, while local experts were interviewed to estimate the healthcare resource used in the management of CMPA. The costs of healthcare resources were obtained from standard, publicly available sources. The direct medical cost of CMPA management was lowest for EHCF+LGG (USD 1,720), followed by SPF (USD 2,090), EHWF (USD 2,791), and AAF (USD 7,881). Compared with other formulas, EHCF+LGG was expected to save USD 370 (SPF), USD 1,071 (EHWF), and USD 6,161 (AAF) in the total cost of CMPA management over 36 months. In conclusion, EHCF+LGG was the most cost-effective strategy for managing non-breastfed infants with CMPA. This strategy was associated with more children developing immune tolerance to cow's milk and being symptom-free, contributing to overall cost-saving potential.
RESUMEN
There has been a rapid expansion in the knowledge of paediatric gastroenterology over the recent decade, with a fast-growing repertoire of diagnostic techniques and management strategies for a wide spectrum of childhood gastrointestinal (GI) diseases. Paediatric GI endoscopy is a core competency every paediatric gastroenterologist should possess, and represents one of the most common procedures performed in children for both diagnostic and therapeutic purposes. Yet there remains a dearth of literature on the utility and outcomes of paediatric GI endoscopy in the Asia-Pacific region. Data on the diagnostic value of paediatric GI endoscopy would be an important aspect of discussion, with the emergence of inflammatory bowel disease (IBD) and eosinophilic GI disease as increasingly common endoscopic diagnoses. Time-based trends in paediatric GI endoscopy do point towards more IBD and gastroesophageal reflux disease-related complications being diagnosed, with a declining incidence of GI bleeding. However, the real-world diagnostic value of endoscopy in Asia must be contextualised to the region-specific prevalence of paediatric GI diseases. Helicobacter pylori infection, particularly that of multidrug-resistant strains, remains a highly prevalent problem in specific regions. Paediatric functional GI disorders still account for the majority of childhood GI complaints in most centres, hence the diagnostic yield of endoscopy should be critically evaluated in the absence of alarm symptoms. GI therapeutic endoscopy is also occasionally required for children with ingested foreign bodies, intestinal polyposis or oesophageal strictures requiring dilation. Endoscopic haemostasis is a potentially life-saving skill in cases of massive GI bleeding typically from varices or peptic ulcers. Advanced endoscopic techniques such as capsule endoscopy and balloon-assisted enteroscopy have found traction, particularly in East Asian centres, as invaluable diagnostic and therapeutic tools in the management of IBD, obscure GI bleeding and intestinal polyposis. State of the art endoscopic diagnostics and therapeutics, including the use of artificial intelligence-aided endoscopy algorithms, real-time confocal laser endomicroscopy and peroral endoscopic myotomy, are expected to gain more utility in paediatrics. As paediatric gastroenterology matures as a subspecialty in Asia, it is essential current paediatric endoscopists and future trainees adhere to minimum practice standards, and keep abreast of the evolving trends in the diagnostic and therapeutic value of endoscopy. This review discusses the available published literature on the utility of paediatric GI endoscopy in Asia Pacific, with the relevant clinical outcomes.

BACKGROUND AND AIMS: Mistreatment in the learning environment is associated with adverse outcomes for residents. Most studies with that regard have been performed in western countries which may have different socio-cultural background and educational and training systems than the non-Western Asian countries. This study aimed (1) to determine the national prevalence of mistreatment in Thai paediatric residents and a correlation with the risk for burnout and other factors and (2) to launch a mistreatment awareness program (MAP) in our training program. METHODS: The study was divided into two phases. Phase 1, an online survey of mistreatment-related questions, was sent to current paediatric residents across the country. Burnout and depression were also self-evaluated by formal screening questions. The results were categorized by the Negative Acts Questionnaire-Revised into five domains of mistreatment: workplace learning-related bullying (WLRB), person-related bullying (PRB), physically intimidating bullying, sexual harassment, and ethnic harassment. Frequent mistreated exposure was defined as if mistreatment occurred >1/week. Phase 2, MAP was conducted by distributing the results of the first phase with some examples of mistreatment events and mistreatment-related videos. After 3 months, at our centre, the survey was resent to evaluate mistreatment. RESULTS: The response rate was 27% (n = 140). We found that 91% experienced ≥1 mistreated situation in the prior 6 months. Most mistreatment domains were WLRB and PRB, and residents were commonly instigated by clinical faculty and nurses. Most (84%) mistreated residents did not report the events. An association between frequent mistreated exposure and burnout was also found (P < 0.001). For Phase 2, the mistreated situations especially the WLRB and PRB domains dropped after the launch of MAP. CONCLUSIONS: Thai paediatric residents frequently perceive mistreatment in their learning environment. Specific aspects of mistreatment, such as WLRB and PRB, should be carefully explored and managed through particular groups of instigators.

BACKGROUND: Cytomegalovirus (CMV) infection is the most common infection following pediatric liver transplantation (LT). Preemptive therapy (PET) is an approach to initiate antiviral treatment for asymptomatic early CMV viremia detected by surveillance testing. However, data on CMV infection after PET are scarce, and the optimal cut-off remains controversial. This study aimed to evaluate the incidence, risk factors, and consequences of CMV infection in pediatric LT using 2 different viral load (VL) cut-offs. METHODS: We retrospectively reviewed patients aged 0-18 years who underwent LT at Ramathibodi Hospital between March 2001 and August 2020. Demographic data, CMV infection, CMV treatment, and consequences of CMV infection were collected. CMV viremia was monitored by a quantitative nucleic acid amplification test. Clinical outcomes were compared after starting antiviral therapy at a low (>400 but <2000 IU/mL) and a high VL cut-off (≥2000 IU/mL). RESULTS: A total of 126 patients were included. CMV infection was 71% (90/126), with an incidence rate of 5.5 per 1000 patient-day. Higher tacrolimus and prednisolone dosages were associated with CMV infection with an adjusted hazard ratio of 1.2 (95%CI 1.0-1.4, p = .02) and 2.4 (95%CI 1.9-3.4, p < .001), respectively. The consequences of CMV infection did not differ significantly for the low and high CMV VL cut-off groups. CONCLUSION: CMV infection in LT recipients is common and is associated with higher tacrolimus and corticosteroid dosage. Additionally, using the CMV VL cut-off at 2000 IU/mL to initiate antiviral therapy is practical and effective in preventing CMV disease.

BACKGROUND: Southeast Asia is the endemic area of hepatitis E virus (HEV) infection. We aimed to determine the seroprevalence of the virus, its association, and the prevalence of chronic infection after pediatric liver transplantation (LT). METHODS: A cross-sectional study was performed in Bangkok, Thailand. Patients aged <18 years who had LT for >2 years underwent serologic and real-time polymerase chain reaction (rt-PCR) tests. Acute HEV infection was defined by the presence of positive anti-HEV immunoglobulin (Ig)M and HEV viremia from the rt-PCR. If the viremia persisted for >6 months, chronic HEV infection was diagnosed. RESULTS: A total of 101 patients had a median age of 8.4 years [interqartile range (IQR): 5.8-11.7]. The seroprevalence of anti-HEV IgG and IgM was 15% and 4%, respectively. Positive IgM and/or IgG were associated with a history of elevated transaminases with an unknown cause after LT (p = 0.04 and p = 0.01, respectively). The presence of HEV IgM was associated with a history of elevated transaminases with an unknown cause within 6 months (p = 0.01). The two patients (2%) diagnosed with chronic HEV infection did not fully respond to the reduction of immunosuppression but responded well to ribavirin treatment. CONCLUSIONS: Seroprevalence of HEV among pediatric LT recipients was not rare in Southeast Asia. Since HEV seropositivity was associated with elevated transaminases of an unknown cause, investigation for the virus should be offered in LT children with hepatitis after excluding other etiologies. Pediatric LT recipients with chronic HEV infection may receive a benefit from a specific antiviral treatment.

PURPOSE: To evaluate the efficacy of Bacillus clausii in the treatment of pediatric constipation. METHODS: A randomized, double-blind, placebo-controlled trial was conducted from January, 2021 to January, 2022 in children aged 1-5 years diagnosed with functional constipation according to Rome IV criteria. They were assigned to receive either B. clausii or placebo, once daily for four weeks. The primary out-come was treatment success (defined as ≥3 spontaneous stools per week and stool consistency grade ≥3 on Bristol stool chart). The secondary outcome was a comparison of stool frequency, consistency (defined by Bristol stool grade), and constipation-related symptoms. RESULTS: This trial enrolled 38 children (B. clausii, n=20 and placebo, n=18). At 4 weeks, no significant difference was noted in the treatment success between B. clausii and placebo groups [45% vs 56%; P=0.52). On within-group analyses, the mean (SD) of Bristol stool grade increased in both the B. clausii [1.7 (0.5) to 2.8 (1.2); P=0.003] and placebo [1.8 (0.5) to 2.8 (1.2); P=0.01] groups. Significant increases in the treatment success rate (22% to 56%, P=0.01) and mean stool frequency per week [3 (0.9) to 4.2 (1.7), P=0.01] were pronounced only in the placebo group. The frequency of painful defecation and large fecal mass were also significantly decreased in both the groups. No serious adverse events were observed. CONCLUSIONS: A 4-week course of B. clausii as the sole treatment was not more effective than a placebo for the management of functional constipation in children aged 1-5 years.

AIM: To evaluate whether pregnancy and birth-related factors are associated with celiac disease (CD) in a large, United States (US)-based mother-child cohort. METHODS: We analysed data gathering from the Massachusetts General Hospital Maternal Child Cohort (MMCC) of children born between 1998 and 2016. Data included the mode of delivery, maternal pregnancy and their offspring characteristics. We searched for CD cases by using diagnosis billing codes. Cox proportional hazard regression models were created to identify variables associated with CD. RESULTS: We identified 44 539 mother-child pairs who had at least one encounter by 5 years old and identified 173 children (0.4%) with CD diagnosis; median age at the diagnosis was 6 years. Overall, the adjusted hazard ratio (aHR) of caesarean delivery for CD was 1.39 (95% CI: 0.99, 1.96, p = 0.06) when compared to children born vaginally. After stratifying for the presence of labour, children born by Caesarean delivery without labour had a higher risk of CD (aHR 1.56; 95%CI: 1.01, 2.41; p = 0.046) while infants born by Caesarean delivery with labour did not (aHR 1.26; 95% CI: 0.83, 1.93; p = 0.28). CONCLUSION: Being born by Caesarean delivery without labour may be associated with an increased risk for CD in the US children.

PURPOSE: To evaluate duplex US findings of the HA in all three postoperative vascular (HA, PV, HV and IVC) complications of paediatric LT for early detection and some helpful secondary signs to determine these vascular complications. MATERIALS AND METHODS: We collected data from 44 post-LT paediatric patients who underwent daily duplex US for seven consecutive days and three months after LT during January 2017-June 2020. Four duplex US parameters of the HA (extrahepatic PSV, intrahepatic PSV, RI and AT) were compared in patients with and without complications. RESULTS: The PSV of the extrahepatic HA in patients with HA complications was higher than that in patients without complications (P value = 0.019). The PSV at 107.7 cm/s is the optimal cut-off parameter associated with HA complications [a sensitivity of 88.9% and a specificity of 80.0% (ROC area is 0.84)]. The intrahepatic RI was higher on the first day than on the last day and gradually decreased in patients without vascular complications (P value = 0.000). The intrahepatic PSV significantly decreased with time when comparing the first and last days in patients without PV and HV-IVC complications (P value = 0.014 and 0.038). In contrast, patients with vascular complications showed no significant decrease. CONCLUSION: The extrahepatic PSV relates to HA complications after paediatric LT but not PV and HV-IVC complications. Non-significantly decreased intrahepatic RI and PSV from the first day to the day of complication diagnosis may correlate with the occurrence of vascular complications.
