Multicenter registry of pediatric inflammatory bowel disease from a developing country.

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.

Clinical Outcomes of Children Diagnosed Dengue-Associated Acute Liver Failure with or without N-Acetylcysteine Treatment: A Retrospective Cohort Study.

OBJECTIVES: N-acetylcysteine (NAC) has been shown to prevent hepatic damage and improve microcirculatory blood flow and oxygen delivery to the tissue. Previous studies have proposed the benefit of NAC in dengue-associated acute liver failure (ALF). However, most studies are descriptive and lack comparison between groups. We aimed to compare the ALF resolution rate and mortality rate of those who received and did not receive NAC treatment. METHODS: A retrospective cohort study was conducted among children aged <15 years who were diagnosed with dengue-associated ALF at a tertiary hospital in Thailand, between January 2002 and July 2019. Demographic and clinical information were collected. Main outcomes were ALF resolution and mortality rate. RESULTS: Thirty-three patients were included of which 16 received NAC treatment (48.5%). Mean ages were 8.5 years (SD 3.7) and mean onset of ALF was 6.3 days (SD 1.6) after onset of fever. The grading of hepatic encephalopathy (HE) and organ failure was not significantly different between the two groups. In the NAC group, 13/16 children were prescribed 100 mg/kg/day of NAC until INR <2 without HE or <1.5 with HE. NAC was initiated 1.1 days (SD 0.3) after the ALF diagnosis. The NAC group showed a higher rate of ALF resolution (75% vs. 53% in the non-NAC group, p = 0.34) with a lower mortality rate (31% vs. 53%, p = 0.36). Side effects of NAC were not found. CONCLUSION: NAC may be beneficial in dengue-associated pediatric ALF. Further well-designed randomized control trials should be carried out.

Anaplastic Large Cell Lymphoma of the Duodenum in a Teenage Girl: Misdiagnosed as an Intramural Duodenal Hematoma.

We report a case of a 13-year-old girl who presented with a 2-month history of intermittent abdominal pain. Laboratory examination showed hepatitis and pancreatitis. Because of persistent vomiting, computed tomography (CT) was performed, which revealed a circumferential soft tissue density in the duodenal wall, causing partial obstruction. Supportive therapy failed. Repeat CT showed no significant change from the initial study. The patient underwent upper endoscopy, which revealed a mass in the second portion of the duodenum, which occluded most parts of the lumen. The histopathological finding was consistent with an anaplastic large cell lymphoma, a rare form of small bowel neoplasm. After the third course of chemotherapy, complete resolution of the mass was noted, and her symptoms were relieved.

Split dose versus full single-dose regimen of polyethylene glycol for bowel preparation in pediatric colonoscopy: a pilot study of randomized controlled trial.

OBJECTIVES: Previous meta-analyses in adults comparing a full single dose vs. split doses of polyethylene glycol with electrolyte solution demonstrated that the split-dose group had a higher rate of successful bowel preparation. To date, no similar study in children has been conducted. Therefore, we compared the efficacy of bowel preparation between the two regimens of polyethylene glycol with electrolyte solution in pediatric colonoscopy. The secondary outcomes were tolerability, acceptability, and compliance. METHODS: An investigator-blinded randomized controlled trial was conducted to enroll children aged 2-18 years who underwent an elective colonoscopy at a teaching hospital between March 2018 and February 2019. Patients were randomly assigned to receive polyethylene glycol with electrolyte solution as a full single dose or two split doses. The Boston Bowel Preparation Scale was used for the efficacy (i.e. successful bowel preparation if score ≥ 6). Secondary outcomes were evaluated by using a standardized questionnaire. RESULTS: A total of 45 colonoscopies (22 in the full single-dose and 23 in the split-dose group) were performed. Mean age was 9.2 years old (SD 4.4). We noted a higher rate of successful bowel preparation in the split-dose group (95% vs. 72%, P = 0.047). Significant higher rate of willingness to repeat the same protocol (83% vs. 36%, P = 0.002) and a trend of lower rate of nausea/vomiting (39% vs. 68%, P = 0.051) in the split-dose group were found. CONCLUSION: The split-dose regimen of polyethylene glycol with electrolyte solution for bowel preparation suggests superior efficacy, potential tolerability, and acceptability as compared to the traditional full single-dose regimen.
