Adequate antiviral treatment lowers overall complications of cytomegalovirus colitis among inpatients with inflammatory bowel diseases.

BACKGROUND: Cytomegalovirus (CMV) colitis significantly complicates the course of inflammatory bowel disease (IBD), frequently leading to severe flare-ups and poor outcomes. The role of antiviral therapy in hospitalized IBD patients with CMV colitis is currently under debate. This retrospective analysis seeks to clarify the influence of antiviral treatment on these patients. METHODS: We retrospectively reviewed IBD patients diagnosed with CMV colitis via immunohistochemistry staining from colonic biopsies at a major tertiary center from January 2000 to May 2021. The study focused on patient demographics, clinical features, risk factors, prognostic indicators, and antiviral treatment outcomes. RESULTS: Among 118 inpatients, 42 had CMV colitis. Risk factors included hypoalbuminemia and antibiotic use. IBD patients with CMV colitis receiving < 14 days of antiviral therapy had higher complication (72% vs. 43%, p = 0.028) and surgery rates (56% vs. 26%, p = 0.017) compared to those without CMV. Adequate antiviral therapy (≥ 14 days) significantly reduced complications in the CMV group (29% vs. 72%, p = 0.006), especially in Crohn's disease (20% vs. 100%, p = 0.015). Independent predictors of IBD-related complications were CMV colitis (Odds Ratio [OR] 3.532, 90% Confidence Interval [CI] 1.012-12.331, p = 0.048), biological treatment failure (OR 4.953, 95% CI 1.91-12.842, p = 0.001), and adequate antiviral therapy (OR 0.108, 95% CI 0.023-0.512, p = 0.005). CONCLUSION: CMV colitis and a history of biological treatment failure increase complication risks in IBD patients. Adequate antiviral therapy significantly mitigates these risks, highlighting its importance in managing IBD patients with CMV colitis.

The trends of pediatric duodenal ulcer and predictors of recurrence.

BACKGROUND: Duodenal ulcer (DU) causes various symptoms in children. The prevalence of Helicobacter pylori (Hp)-associated DU has been reducing in some regions, yet the updated trend in Taiwan is unknown. Risk factors of DU recurrence have not been comprehensively investigated in children. METHODS: This retrospective study included children diagnosed with DU to evaluate the demographics, symptoms, diagnostics, treatment, and outcomes. Specific populations (infant, surgery required) were sorted for subgroup analysis. Predictors of DU recurrence was analyzed in patients who received endoscopic follow-ups. RESULTS: A total of 488 children were included. Most patients were male (72.5%), school-aged (11.3 ± 4.8 years old), and with varied underlying diseases in one-fifth. The annual incidences were around 3-5%, with a declining trend of case numbers and the Hp-positive proportion. Hp infection, concurrent gastric ulcer, perforation, and mortality were noted in 32.7%, 16%, 1.6%, and 1% of patients. Patients with or without Hp infection showed different clinical features but similar outcomes. The characteristics of subpopulations were depicted respectively. Male sex, lower Hb level, and perforation were independent risk factors associated with recurrence. CONCLUSIONS: Hp-positive DU seems to wane. Patients with male sex, lower Hb level, or perforation at diagnosis carried a higher risk of recurrence, which may warrant active surveillance and endoscopic follow-up.

Primary endoscopic variceal ligation reduced acute variceal bleeding events but not long-term mortality in pediatric-onset portal hypertension.

BACKGROUND/PURPOSE: Esophageal variceal bleeding (EVB) is a medical emergency in patients with portal hypertension (PHT). However, studies on the long-term outcomes of prophylactic endoscopic variceal ligation (EVL) in pediatric-onset PHT are lacking. METHODS: Between 1999 and 2020, patients who received EVL in the Electronic Report System of the Pediatric Endoscopy Unit were included in this retrospective study. EVL was classified as primary prophylaxis when it was performed for esophageal varices (EVs) without previous bleeding. If it was implemented in acute EVB, the subsequent EVL was classified as secondary prophylaxis. RESULTS: Fifty-eight patients aged 10 months to 33 years with 31 males were included. Thirty-eight patients were classified as primary prophylaxis group, and twenty, secondary prophylaxis group. The primary prophylaxis group experienced fewer 5-year EVB events than the secondary prophylaxis group (cumulative risk: 14.4% versus 32.4%). Still, it didn't significantly affect overall survival and biliary atresia transplant-free survival. Long-term mortality was significantly associated with higher serum direct bilirubin levels (≥0.55 mg/dL) and lower albumin levels (≤2.54 mg/dL) at the first EVL. Aspartate aminotransferase-to-platelet ratio index (APRI) with a cut-off value of 1.24 helped to predict EV presence at the initial esophagogastroduodenoscopy (EGD) (AUROC = 0.762, sensitivity 75.0%, and specificity 66.7%). CONCLUSION: Primary prophylactic EVL, despite reducing acute EVB, may not change overall survival and biliary atresia transplant-free survival. APRI > 1.24 may predict EV presence at the first EGD and help to schedule a surveillance EGD. Higher direct bilirubin and lower albumin levels at the first EVL may relate to long-term mortality.

High initial bowel resection rate and very-early-onset inflammatory bowel disease - A challenge in a low-prevalence area.

BACKGROUND: Inflammatory bowel diseases (IBD) include ulcerative colitis (UC) and Crohn's disease (CD). The incidence in children and adolescents has risen since the 21st century globally, including Taiwan. The study aimed to disclose the characteristics and outcome of pediatric IBD (pIBD) patients in a tertiary center for the past two decades. METHODS: We retrospectively reviewed the charts of pIBD children from 2000 to 2018 in a tertiary center in Northern Taiwan. Demographics, presentations, diagnostic modalities, treatment, and outcomes were analyzed. RESULTS: A total of 38 cases were enrolled, including 27 CD and 11 UC patients. An almost 3-folds increase in incidence after 2010 was observed. Twelve cases (32%) were early-onset, and six of them (16%) were very-early-onset; four of them were detected with single-gene mutations [XIAP, TTC7A (2 siblings), and ZAP70]. Eleven CD patients (40.7%) received bowel resection at the onset, and another two (7.4%) had bowel resection years after the diagnosis. Initial bowel resection was associated with fibrostenotic/penetrating behavior, early-onset disease, and growth failure. CONCLUSION: This study demonstrated an increased incidence of pIBD in the past two decades in Taiwan, a low-prevalence region. The initial high bowel resection rate in CD was related to the fibrostenotic and/or penetrating behavior, younger age at diagnosis, and growth failure.

Clinical significance of incidental common bile duct dilatation in children: A 10-year single medical center experience.

BACKGROUND: With the widespread use of abdominal ultrasonography (US), incidental detection of common bile duct (CBD) dilatation is common in pediatric populations. This study investigated the causes and clinical significance of CBD dilatation in children without biliary symptoms, jaundice, or causative lesions in US. METHODS: We retrospectively reviewed pediatric patients with CBD dilatation from July 2013 to June 2023. All cases were detected via abdominal US. We analyzed the patients' clinical manifestations, laboratory data, diagnosis, underlying diseases, and clinical course. RESULTS: In a total of 687 patients enrolled, 338 met inclusion criteria (90 in hepatobiliary, 248 in CBD dilatation group). Of 128 patients with incidental CBD dilatation who underwent regular US examinations, 91 (71.1%) experienced resolution during follow-up. The proportion of patients with intrahepatic duct dilatation was significantly higher in the non-resolution group (p = 0.038). General health examination group had significant smaller CBD diameter compared to the gastrointestinal and infection groups. Correlation analysis found starting point of resolution decline at 3.24 mm (all-inclusive) and 2.51 mm (infant group) CBD diameter. CONCLUSIONS: Most children with incidental CBD dilatation did not have abnormal hepatobiliary function or other sonographic abnormalities. They usually remained asymptomatic and experienced uneventful clinical courses.

Cytomegalovirus Diseases of the Gastrointestinal Tract in Immunocompetent Patients: A Narrative Review.

Cytomegalovirus (CMV) is a potential pathogen that causes gastrointestinal (GI) tract diseases regardless of host immunity. In contrast to immunocompromised individuals, immunocompetent patients lack a comprehensive overview of the gastrointestinal manifestations. This study aims to provide a comprehensive summary of the current evidence regarding presentations, diagnostics, management, risk assessment, and outcomes in immunocompetent patients with CMV GI disease. A thorough literature search of English publications up to April 2022 was conducted across electronic databases to identify relevant articles, with eligible case series selected for detailed analysis. The majority of immunocompetent patients affected by CMV GI disease are typically elderly, critically ill, or burdened with comorbidities that compromise immunity. Clinical presentations range from subtle symptoms to severe surgical conditions, including instances of mortality. Specific clinical presentations, blood test results, or endoscopic features are lacking, necessitating reliance on histopathological tests such as immunohistochemistry staining for diagnosis. While antiviral therapy may offer benefits in improving outcomes, careful individual assessment is warranted due to diverse comorbidities and potential side effects. Mortality rates vary considerably based on underlying medical conditions and therapeutic approaches. It is imperative for clinicians to maintain vigilance for CMV GI disease among high-risk groups, despite their baseline immunocompetence, in order to enhance clinical outcomes.

Comparative Analysis of Cytomegalovirus Gastrointestinal Disease in Immunocompetent and Immunocompromised Patients.

BACKGROUND: Cytomegalovirus (CMV) gastrointestinal (GI) diseases impact both immunocompromised and immunocompetent individuals, yet comprehensive studies highlighting the differences between these groups are lacking. METHODS: In this retrospective study (January 2000 to July 2022) of 401 patients with confirmed CMV GI diseases, we categorized them based on immunological status and compared manifestations, treatments, outcomes, and prognostic factors. RESULTS: The immunocompromised patients (n = 193) showed older age, severe illnesses, and higher comorbidity rates. GI bleeding, the predominant manifestation, occurred more in the immunocompetent group (92.6% vs. 63.6%, p = 0.009). Despite longer antiviral therapy, the immunocompromised patients had higher in-hospital (32.2% vs. 18.9%, p = 0.034) and overall mortality rates (91.1% vs. 43.4%, p < 0.001). The independent factors influencing in-hospital mortality in the immunocompromised patients included GI bleeding (OR 5.782, 95% CI 1.257-26.599, p = 0.024) and antiviral therapy ≥ 14 days (OR 0.232, 95% CI 0.059-0.911, p = 0.036). In the immunocompetent patients, age (OR 1.08, 95% CI 1.006-1.159, p = 0.032), GI bleeding (OR 10.036, 95% CI 1.183-85.133, p = 0.035), and time to diagnosis (OR 1.029, 95% CI 1.004-1.055, p = 0.021) were significant prognostic factors, with the age and diagnosis time cut-offs for survival being 70 years and 31.5 days, respectively. CONCLUSIONS: GI bleeding is the most common manifestation and prognostic factor in both groups. Early diagnosis and effective antiviral therapy can significantly reduce in-hospital mortality.

Twenty years' experience of midgut malrotation and volvulus in a tertiary center in northern Taiwan: A retrospective study.

BACKGROUND: Early diagnosis and surgical intervention for midgut malrotation with bowel obstruction are crucial. We aimed to identify risk factors for adverse outcomes in infants with midgut malrotation and to develop a prediction model. METHODS: We reviewed the operation records of infants surgically diagnosed with midgut malrotation at Chang Gung Children's Medical Center between January 2000 and December 2020. Patients were classified into the poor-outcome group (PO) if they underwent bowel resection or experienced mortality; all others were categorized as the favorable-outcome group (FO). Data on demographics, initial presentations, laboratory results, radiographic or sonographic findings, maternal conditions, and outcomes were collected and analyzed. Fisher's exact test, the independent sample t-test, and the Mann-Whitney test were utilized for comparative analysis when suitable. RESULTS: The study included 103 infants. Eleven were in the PO group, and 92 were in the FO group. Initial presentations such as respiratory distress, poor activity, and shock status were notably more prevalent in the PO group. The INR, hemoglobin, HCO3, base excess, and aspartate transaminase values showed significant variation between the two groups. Multivariate analysis identified that lower hemoglobin (OR 0.677, p = 0.043) and higher AST (OR 1.036, p = 0.044) were independent predictors of adverse outcomes. An AST/Hb ratio of <3.78 demonstrated a high negative predictive value (98.6%) for an adverse outcome in midgut malrotation. CONCLUSIONS: Prompt diagnosis and surgical treatment of midgut malrotation are vital to prevent bowel resection or mortality. The independent predicting factors for poor outcomes include low hemoglobin and elevated AST levels.

Effect of the coronavirus disease 2019 pandemic on pediatric emergency department visits for acute gastroenteritis evaluated using a validated clinical severity score.

BACKGROUND: The coronavirus disease 2019 (COVID-19) outbreak that began in late 2019 has significantly affected quality of life and healthcare. Approaches to prevent the spread of COVID-19 have also affected the prevalence of other diseases. This retrospective review evaluated pediatric emergency department (PED) volume, in terms of children with acute gastroenteritis (AGE), and changes in AGE severity before versus during the COVID-19 pandemic in a tertiary medical center in Taiwan. METHODS: Patients who visited the PED and were diagnosed with AGE during the 70-day COVID-19 lockdown in 2021, or the identical period in 2020, were compared using a clinically validated AGE severity score, the modified Vesikari score (MVS), and additional parameters. RESULTS: During the COVID-19 outbreak, there was a 61.4% reduction in the number of children with AGE visiting the PED. In that period, the AGE severity score was similar compared to the pre-pandemic period (9.00 vs. 8.57, p = 0.273). The mean C-reactive protein (CRP) level (55.7 vs. 40.6 mg/L, p < 0.001) and rate of antibiotics use (48% vs. 23.5%, p < 0.001) were higher during the outbreak than the pre-pandemic period. CONCLUSION: The number of children with AGE visiting the PED decreased during the COVID-19 outbreak, while disease severity was unchanged compared to the pre-pandemic period. The use of antibiotics during the COVID-19 pandemic warrants further investigation.

Fecal microbiota transplantation for treatment of refractory or recurrent Clostridioides difficile infection in Taiwan: a cost-effectiveness analysis.

Background: Compared to antibiotic treatment, fecal microbiota transplantation (FMT) is a more effective treatment for refractory or recurrent CDI (rCDI). Patients with inflammatory bowel disease (IBD) have a higher incidence of CDI and worse outcomes. There has been no study from Asia to evaluate the cost-effectiveness of FMT for overall rCDI patients and rCDI patients with IBD. Methods: We applied a Markov model with deterministic and probabilistic sensitivity analyses to evaluate the cost and effectiveness of different treatments for rCDI patients with a time horizon of 1 year from the payer's perspective. We compared the cost and clinical outcomes of FMT through colonoscopy to two antibiotics (vancomycin and fidaxomicin) using data from Chang Gung Memorial Hospital, Taoyuan, Taiwan. Results: Compared to vancomycin, FMT was cost-effective in overall rCDI patients as well as IBD patients with rCDI [USD 39356 (NT$1,101,971.98)/quality-adjusted life year (QALY) gained in overall patients; USD65490 (NT$1,833,719.14)/QALY gained in IBD patients]. Compared to fidaxomicin, FMT was only cost-effective in overall rCDI patients [USD20255 (NT$567,133.45)/QALY gained] but slightly increased QALY (0.0018 QALY gained) in IBD patients with rCDI. Conclusion: FMT is cost-effective, compared to vancomycin or fidaxomicin, for the treatment of rCDI in most scenarios from the payers' perspective in Taiwan.

Application of Argon Plasma Coagulation for Gastrointestinal Angiodysplasia in Children- Experience From a Tertiary Center.

Background: Argon plasma coagulation (APC) has been applied in adults to treat various diseases, including vascular lesions in the gastrointestinal (GI) tract. However, angiodysplasia (AD) is an uncommon cause of pediatric GI bleeding, while the experience of treating AD with APC was rarely reported. Methods: Five children with AD in the GI tract successfully treated with APC were reviewed. Results: Three of the five patients were girls, and the age at diagnosis ranged from 1.5 months to 10.5 years of age. One patient with gastric AD manifested with tarry stool, and the rest had colonic AD, which caused various degrees of bloody stool. Three patients had evident anemia. All patients received an endoscopic diagnosis, and two had compatible findings in radiographic exams. Each patient underwent one APC treatment session, and none encountered procedure-related complications or re-bleeding. Conclusion: AD can be an etiology of GI bleeding even in neonates. APC is an effective and safe therapy for symptomatic AD in children.

Clostridium innocuum infection in hospitalised patients with inflammatory bowel disease.

BACKGROUND: Clostridium innocuum (CI) infection can lead to creeping fat in Crohn's disease and is associated with intestinal strictures. At present, no clinical study ever has evaluated the role of CI infection in inflammatory bowel disease (IBD). MATERIALS AND METHODS: In this retrospective cohort study, we enrolled hospitalized IBD patients with culture results for both CI and Clostridioides difficile (CD) in a medical center between October 2019 and April 2021. They were divided into the CI (CI+/CD-), control (CI-/CD-), coinfection (CI+/CD+), and CD (CI-/CD+) groups. We analyzed the risk factors, clinical presentations, and outcomes by comparing the CI and control groups. RESULTS: We enrolled a total of 90 patients, including 22, 39, 13, and 16 patients in the CI, control, coinfection, and CD groups. The incidence rates of CI (CI+) and CD (CD+) were 39% (35/90) and 32% (29/90), respectively. We analyzed the differences between CI and control groups. We identified the use of steroid (77.3% vs. 46.2%, P = 0.018) and 5-aminosalicylic acid (90.9% vs. 64.1%, P = 0.022) as risk factors of CI infection. Clinical analysis showed that more patients in CI group presented with bloody stool (77.3% vs. 51.3%, P = 0.046). Although CI group had significantly lower overall occurrence of intraabdominal abscess (0% vs. 17.9%, P = 0.042), it showed a lower clinical remission rate (50% vs. 87.5%, P = 0.044) and higher Mayo score at the end of follow-up (10 points vs. 3 points, P = 0.008) in ulcerative colitis. CONCLUSIONS: CI infection may lead to a poorer clinical remission in ulcerative colitis. We should take it into consideration in IBD patents with active inflamamtion or refractory diarrhea with or without CD infection. Precise identification of CI is imperative to guide approproate antimicrobial therapy because of its intrinsic vancomycin resistance nature.

Characteristics and Risk Factors for Ischemic Ovary Torsion in Children.

Identifying ischemic ovary as a complication of ovary torsion (OT) is a significant challenge in children. This study identified risk factors for ischemic OT among pediatric OT patients to prevent delayed treatment. This retrospective study included pediatric inpatients who underwent operation for OT over 20 years. We employed multivariable logistic regression to find the risk factors associated with ischemic OT. Among the 118 patients included in this study, 78 (66.1%) had ischemic OT. Patients with ischemic OT tended to be younger; had more frequent vomiting; and had elevated White blood cell (WBC), C-Reactive protein (CRP), and segments in comparison with non-ischemic OT patients. Multivariable regression showed increased odds of ischemic ovary torsion, associated with higher WBC (12.3 × 103/mm3 vs. 8.7 × 103/mm3, p < 0.001), CRP (50.4 mg/L vs. 8.4 mg/L, p < 0.001), and vomiting (55.1% vs. 25%, p = 0.002) than in non-ischemic patients. A receiver-operating characteristic (ROC) analysis indicated that patients with vomiting, leukocytosis, or CRP ≧ 40 mg/L were more likely to have ischemic OT (sensitivity, 92%; specificity, 54%; PPV, 79.6; NPV, 78.9%). Ischemic OT is common among pediatric OT patients. The presence of potential risk factors of vomiting, leukocytosis, and CRP more significant than 40 mg/L may assist clinicians in ensuring an expedited surgical treatment.

Cytomegalovirus Diseases of the Gastrointestinal Tract.

Cytomegalovirus (CMV) infection of the gastrointestinal (GI) tract can be fatal. However, very few studies have provided comprehensive analyses and specified the differences in symptoms observed in different parts of the GI tract. This study aimed to comprehensively analyze clinical manifestations and management of GI CMV disease. This retrospective cohort study enrolled the patients who had CMV diseases of the GI tract proved by CMV immunohistochemistry stain from the pathology database in a 4000-bed tertiary medical center between January 2000 and May 2021. The patient characteristics, clinical manifestations, endoscopic features, treatments, outcomes, and prognostic factors were analyzed. A total of 356 patients were enrolled, including 46 infected in the esophagus, 76 in the stomach, 30 in the small intestine, and 204 in the colon. In total, 49.4% patients were immunocompromised. The overall in-hospital mortality rate was 20.8%: CMV enteritis had the highest rate (23.3%). Sixty percent of patients received antiviral treatment and 16% were administered both intravenous and oral anti-viral drugs (Combo therapy, minimal and mean treatment duration were 14 and 39.9 ± 25 days). Prognostic factors of in-hospital mortality included age, immune status, albumin level, platelet count, GI bleeding, time-to-diagnosis, and Combo therapy. In the survival analysis, immunocompetent patients receiving Combo therapy had the best survival curve, and immunocompromised patients receiving non-Combo therapy had the worst survival curve. Combo therapy ≥14 days resulted in a better outcome for both immunocompromised and immunocompetent patients. In conclusion, CMV GI diseases affect both immunocompromised and immunocompetent hosts, and a complete treatment course should be considered for patients with poor prognostic factors.

Risk Factors, Clinical and Endoscopic Features, and Clinical Outcomes in Patients with Cytomegalovirus Esophagitis.

Cytomegalovirus (CMV) esophagitis is the second most common CMV disease of the gastrointestinal tract. This study aims to comprehensively analyze risk factors, clinical characteristics, endoscopic features, outcomes, and prognostic factors of CMV esophagitis. We retrospectively collected data of patients who underwent esophageal CMV immunohistochemistry (IHC) staining between January 2003 and April 2021 from the pathology database at the Chang Gung Memorial Hospital. Patients were divided into the CMV and non-CMV groups according to the IHC staining results. We enrolled 148 patients (44 CMV and 104 non-CMV patients). The risk factors for CMV esophagitis were male sex, immunocompromised status, and critical illness. The major clinical presentations of CMV esophagitis included epigastric pain (40.9%), fever (36.4%), odynophagia (31.8%), dysphagia (29.5%), and gastrointestinal bleeding (29.5%). Multiple diffuse variable esophageal ulcers were the most common endoscopic feature. The CMV group had a significantly higher in-hospital mortality rate (18.2% vs. 0%; p < 0.001), higher overall mortality rate (52.3% vs. 14.4%; p < 0.001), and longer admission duration (median, 24 days (interquartile range (IQR), 11−47 days) vs. 14 days (IQR, 7−24 days); p = 0.015) than the non-CMV group. Acute kidney injury (odds ratio (OR), 174.15; 95% confidence interval (CI), 1.27−23,836.21; p = 0.040) and intensive care unit admission (OR, 26.53; 95% CI 1.06−665.08; p = 0.046) were predictors of in-hospital mortality. In conclusion, the mortality rate of patients with CMV esophagitis was high. Physicians should be aware of the clinical and endoscopic characteristics of CMV esophagitis in high-risk patients for early diagnosis and treatment.

Therapeutic Efficacy of Nasoenteric Tube Feeding in Children Needing Enteral Nutrition.

Background: There is limited information on therapeutic benefits and tube-related complications of pediatric nasoenteric (NE) tube feeding. We viewed, from different clinical aspects, NE tube feeding in children who are under intolerable conditions. Methods: A 10-years retrospective study enrolled 77 pediatric patients who underwent an endoscopic-guided placement of the NE tube for enteral nutrition. The evaluated data, including growth parameters, feeding volume, parenteral nutrition (PN) dependence, and nutritional markers [serum hemoglobin (Hb) and albumin] before and after NE tube feeding were compared. Tube-related complications and major adverse events were also recorded. Results: A total of 77 patients (including 50 males) underwent 176 endoscopic-guided placements of the NE tube with an average duration of 133.7 (6.0-1,847.3) days. The gastroesophageal reflux disease-related symptoms (vomiting, desaturations, and aspiration pneumonia) improved in 71.4% of patients. Feeding volume increased significantly after intervention, especially in patients with delayed gastric emptying, from 144.8 ± 28.5 to 1,103.1 ± 524.7 ml/days (p < 0.001). Weaning from PN was successfully achieved in 84.3% of patients with an average of 9.33 ± 7.30 days. About 16 patients (20.8%) were subsequently highly compatible with oral feeding after NE tube placement for an average of 24.7 ± 14.1 days. Patients either without neurologic dysfunction or with no ventilator-dependent status had a higher chance of shifting to oral feeding. Weight-for-age z-scores increased by 0.15 ± 1.33 after NE tube intervention. One NE tube-related adverse event, which caused bowel perforation at 6 days post-insertion, was recorded. No direct tube-related mortality was observed. Conclusions: Endoscopic-guided NE tube placement is a relatively safe, non-invasive procedure for pediatric patients who require enteral nutrition. Feeding via NE tube showed beneficial effects such as improvement in symptoms, PN weaning, and maintenance of body growth without major tube-related complications.

Efficacy of Intravenous Immunoglobulin/Exchange Transfusion Therapy on Gestational Alloimmune Liver Disease.

Background: Gestational alloimmune liver disease (GALD) is a rare but critical cause of neonatal liver failure. After discovering the maternal-fetal alloimmune mechanism, intravenous immunoglobulin (IVIG) with or without exchange transfusion (ET) has gradually replaced antioxidant cocktails as the first-line therapy. Whether such therapy changes the outcome of neonates with GALD is yet to be defined. Method: We reported a pair of twins with discordant presentations, mild and self-limited in the older, whereas liver failure in the younger, who was successfully rescued by ET and IVIG. To investigate the outcome after therapeutic alteration, 39 cases between 2005 and 2020 from literature research were collected. Results: Half of the collected cases (47.1%) were preterm. Common presentations were ascites, jaundice, respiratory distress, hepatomegaly, and edema. Leading laboratory abnormalities were coagulopathy, hypoalbuminemia, and elevated serum ferritin. Salivary gland biopsy and magnetic resonance imaging detected extrahepatic siderosis in 70% (14/20) and 56% (14/25), respectively. IVIG, ET, and liver transplantation were performed in 19 (48.7%), 15 (38.5%), and 8 (20.5%) patients, respectively. The overall survival (OS) rate and native liver survival (NLS) rate were 64.1% (25/39) and 43.6% (17/39), respectively. Although the compiled results did not support a significant benefit, the OS and NLS were higher in the IVIG with/without ET group compared with those treated with conventional therapy [OS (70 vs. 57.9%) and NLS (55 vs. 31.6%), respectively]. Conclusion: A high index of suspicion for GALD is crucial when facing a neonate with liver failure. Despite no significant influence on the outcome over conventional therapy in such a rare and detrimental disease, IVIG with or without ET can be worth trying before resorting to liver transplantation, which is resource-demanding and technique-challenging in small infants.

Clinical Presentations, Diagnosis, and Management for Pediatric Antral Web-A 20-Year Experience of a Referral Center.

Background: Antral web is a rare cause of gastric outlet obstruction in children. The presentation is diverse, depending on the degree of obstruction. Unfortunately, the guidance of management is still lacking. Methods: This study retrospectively evaluated the presentations, management, and outcomes of the pediatric antral web based on a 20-year experience in a referral center. Results: A total of 23 cases were included. The median age of diagnosis was 10 months (interquartile range, IQR, 0.8-23 months). Main presentations comprised vomiting (83%) and upper gastrointestinal (UGI) bleeding (48%). Concurrent gastric ulcers were common (68%). A total of 13 cases (57%) underwent interventional treatment. The median duration from diagnosis to intervention (DtI) was 10 days, but five with longer DtI, ranged from 30 to 755 days. Among the 15 cases with concurrent gastric ulcers, 10 patients received intervention, immediately in six but delayed in four. Surgical treatments (N = 12) achieved a cure in 11, with one rescued by endoscopic treatment. Conclusions: Children who suffer from early gastric ulcers with outlet obstruction shall raise the suspicion of the antral web. Complete obstruction madates early intervention. Around half of the cases with adequate feeding and growth need no intervention. Recurrent obstructive symptoms or adjacent ulcers justify a switch from observation to intervention to avoid complications or growth faltering.

Serum Trace Element Levels and Their Correlation with Picky Eating Behavior, Development, and Physical Activity in Early Childhood.

Trace elements are vital components for healthy growth, development, and physical activity. The aim of this study was to investigate the relationship between trace element (iron, zinc, copper) deficiencies and picky eating behavior, development level, and physical activity level. This cross-sectional study involved 203 children aged 4-7 years; picky eating behavior, development level, and physical activity level were assessed through questionnaires. Zinc deficiency has the highest prevalence (37.4%); 67.5% of the children were assessed as picky eaters. Children with picky eating behaviors, poor development level, or poor physical activity level have significantly lower zinc levels, and higher prevalence of zinc deficiency. Pearson's correlation coefficient indicated a positive correlation between serum zinc level and development scores (r = 0.221, p = 0.002) and physical activity scores (r = 0.469, p < 0.001). In multivariate analysis, zinc deficiency independently related to picky eating (OR = 2.124, p = 0.037, CI = 1.042-4.312), developmental level (OR = 0.893, p = 0.022, CI = 0.810-0.984), and physical activity level (OR = 0.785, p < 0.001, CI = 0.700-0.879). In conclusion, the prevalence of zinc deficiency in children aged 4-7 was high, especially in picky eaters. Zinc deficiency was significantly associated with low development and poor physical activity in early childhood.
