RESUMEN
OBJECTIVES: To investigate the clinical characteristics, treatment, and prognosis of children with perianal fistulizing Crohn's disease (pfCD). METHODS: A retrospective analysis was conducted on the children, aged 6-17 years, who were diagnosed with Crohn's disease (CD) from April 2015 to April 2023. According to the presence or absence of perianal fistulizing lesions, they were divided into two groups: pfCD (n=60) and non-pfCD (n=82). The two groups were compared in terms of clinical characteristics, treatment, and prognosis. RESULTS: The incidence of pfCD was 42.3% (60/142). The proportion of males in the pfCD group was higher than that in the non-pfCD group. Compared with the non-pfCD group, the pfCD group had a significantly higher proportion of children with involvement of the colon and small intestine or those with upper gastrointestinal lesions (P<0.05). Compared with the non-pfCD group, the pfCD group had a significantly higher rate of use of infliximab during both induction and maintenance treatment (P<0.05). In the pfCD group, the children with complex anal fistula accounted for 62% (37/60), among whom the children receiving non-cutting suspended line drainage accounted for 62% (23/37), which was significantly higher than the proportion among the children with simple anal fistula patients (4%, 1/23) (P<0.05). There were no significant differences between the two groups in mucosal healing rate and clinical remission rate at week 54 of treatment (P>0.05). The pfCD group achieved a fistula healing rate of 57% (34/60) at week 54, and the children with simple anal fistula had a significantly higher rate than those with complex anal fistula (P<0.05). CONCLUSIONS: There is a high incidence rate of pfCD in children with CD, and among the children with pfCD, there is a high proportion of children with the use of biological agents. There is a high proportion of children receiving non-cutting suspended line drainage among the children with complex anal fistula. The occurrence of pfCD should be closely monitored during the follow-up in children with CD.

A girl aged 12 years and 2 months presented with recurrent abdominal pain and vomiting for more than 2 years and arthrodynia for 3 months. She was diagnosed with recurrent acute pancreatitis with unknown causes and had been admitted multiple times. Laboratory tests showed recurrent significant increases in fasting serum triglyceride, with elevated immunoglobulin and positive antinuclear antibody. The girl was improved after symptomatic supportive treatment. The girl developed arthrodynia with movement disorders 3 months before, and proteinuria, hematuria, and positive anti-double-stranded DNA antibody were observed. The renal biopsy was performed, and the pathological examination and immunofluorescence assay suggested diffuse lupus nephritis (type â £). She was finally diagnosed with systemic lupus erythematosus (SLE), lupus nephritis (type â £), and recurrent acute pancreatitis. Pancreatitis was suspected to be highly associated with SLE. She was treated with oral hydroxychloroquine sulfate and intravenous methylprednisolone sodium succinate and cyclophosphamide. Arthrodynia was partially relieved. She was then switched to oral prednisone acetate tablets. Intravenous cyclophosphamide and pump infusion of belimumab were regularly administered. Now she had improvement in arthrodynia and still presented with proteinuria and hematuria. It is concluded that recurrent acute pancreatitis may be the first clinical presentation of SLE. For pancreatitis with unknown causes, related immunological parameters should be tested, and symptoms of the other systems should be closely monitored to avoid delaying the diagnosis.

OBJECTIVES: To evaluate the effectiveness of induction therapy with exclusive enteral nutrition (EEN) in pediatric Crohn's disease (CD). METHODS: A retrospective analysis was performed on the medical data of 62 children with CD who received EEN in Children's Hospital, Zhejiang University School of Medicine, from March 2013 to August 2021. The medical data included general information and height, weight, Pediatric Crohn's Disease Activity Index (PCDAI), Crohn's Disease Endoscopic Index of Severity, C-reactive protein, erythrocyte sedimentation rate, and serum albumin level before treatment and after 8 weeks of treatment. The changes in the above indicators were compared before and after treatment. RESULTS: Among the 62 children with CD, there were 39 boys (63%) and 23 girls (37%), with a mean age of (11.9±3.0) years at diagnosis. Among the 55 children who completed EEN treatment for at least 8 weeks, 48 (87%) achieved clinical remission at week 8. PCDAI at week 8 was significantly lower than that before treatment (P<0.001). Except for 17 children with involvement of the small intestine alone and 3 children with involvement of the colon who did not receive colonoscopy reexamination, the remaining 35 children with involvement of the colon received colonoscopy reexamination after the 8-week EEN treatment. Of the 35 children, 29 (83%) achieved mucosal healing. As for the 48 children who achieved clinical remission at week 8, there were significant improvements in height-for-age Z-score and body mass index-for-age Z-score at week 8 (P<0.01). As for the 7 children who did not achieve clinical remission at week 8, there were no significant changes in height-for-age Z-score and body mass index-for-age Z-score at week 8 (P>0.05). CONCLUSIONS: The 8-week EEN treatment has a good effect on clinical remission and mucosal healing in children with CD. For the children with CD achieving clinical remission, EEN can improve their height and body mass index.

A boy aged 14 years had abdominal pain as the major manifestation, with elevated serum amylase and lipase. Abdominal ultrasound performed early after onset in another hospital showed enlargement of the pancreas and a reduction in echo. Magnetic resonance cholangiopancreatography (MRCP) showed pancreatic duct dilation and an unclear image of the head of the pancreas. Acute pancreatitis was considered. However, his symptoms were not relieved after fasting, fluid infusion, anti-acid therapy, and somatostatin therapy. Then, abdominal CT scan and MRCP found multiple low-density lesions of the pancreas and enlargement of the hilar and retroperitoneal lymph nodes. Exploratory laparotomy found pancreatic edema and multiple hilar nodules with unclear boundaries, and pathological biopsy showed anaplastic large-cell lymphoma. Since the liver, the spleen, bone marrow, and the central nervous system were not involved, he was diagnosed with stage III primary pancreatic lymphoma. After vindesine and dexamethasone were used to reduce tumor load, the patient underwent vindesine-pirarubicin-asparaginase-dexamethasone chemotherapy once and vinorelbine-dexamethasone chemotherapy 8 times. Imaging examination still showed multiple low-density lesions of the pancreas and retroperitoneal lymph node enlargement. His parents discontinued treatment. It is concluded that the rare causes of acute pancreatitis with poor response to conventional treatment should be considered, especially for patients with abdominal lymph node enlargement. Extranodal lymphoma should be considered, and lymph node biopsy should be performed as early as possible to confirm diagnosis. The prognosis of pancreatic lymphoma is associated with clinical stage and pathology.

OBJECTIVE: To study the clinical features and prognosis of gastrointestinal injury caused by foreign bodies in the upper gastrointestinal tract in children. METHODS: A retrospective analysis was performed for the clinical data of 217 children who were diagnosed with foreign bodies in the upper gastrointestinal tract complicated by gastrointestinal injury by gastroscopy from January 2011 to December 2016, including clinical features, gastroscopic findings, complications, and prognosis. RESULTS: Among the 217 children, 114 (52.5%) were aged 1-3 years. The most common foreign body was coin (99/217, 45.6%), followed by hard/sharp-edged food (45/217, 20.7%) and metal (35/217, 16.1%). The most common gastrointestinal mucosal injury was ulceration (43.8%), followed by erosion (33.2%). Compared with other foreign bodies, button cells were significantly more likely to cause esophageal perforation (P<0.01). The esophagus was the most commonly injured organ (207/217, 95.4%). Of all the 217 children, 24 (11.1%) experienced infection. The children with perforation caused by foreign bodies had a significantly higher incidence rate of infection than those with ulceration caused by foreign bodies (P=0.003). Of all the 217 children, 204 (94.0%) underwent successful endoscopic removal of foreign bodies. Among these children, 98 were hospitalized due to severe mucosal injury and were given anti-infective therapy, antacids, and supportive care including enteral nutrition through a nasogastric tube and/or parenteral nutrition. Of all the children, 10 left the hospital and were lost to follow-up, and all the other children were improved and discharged. CONCLUSIONS: Most cases of foreign bodies in the upper gastrointestinal tract occur at 1-3 years of age. Coin, hard/sharp-edged food, and metal are the most common foreign bodies. Button cells are more likely to cause esophageal perforation. The incidence rate of secondary infection increases with the increasing severity of gastrointestinal mucosal injury. Children undergoing endoscopic removal of foreign bodies and enteral nutrition through a nasogastric tube tend to have a good prognosis.

BACKGROUND: The aim of this study was to compare nasogastric (NG) feeding with nasojejunal (NJ) feeding when treating pediatric patients with acute pancreatitis (AP). METHODS: We performed a single-center, prospective, randomized, active-controlled trial involving 77 pediatric patients with AP from April 2014 to December 2017. The patients were randomized into two groups: the NG tube feeding group (34 patients) and the NJ tube feeding group (33 patients). The primary outcome measures included the enteral nutrition intolerance, the length of tube feeding time, the recurrent pain of pancreatitis and complications. RESULTS: A total of 62 patients with AP (31 patients for each group) came into the final analysis. No differences were found in baseline characteristics, pediatric AP score and computed tomography severity score between the two groups. Three (9.7%) patients in the NG group and one (3.2%) patient in the NJ group developed intolerance (relative risk = 3.00, 95% confidence interval 0.33-27.29, P = 0.612). The tube feeding time and length of hospital stay of the NG group were significantly shorter than those of the NJ group (P = 0.016 and 0.027, respectively). No patient died in the trial. No significant differences were found in recurrent pain, complications, nutrition delivery efficacy, and side effects between the two groups. CONCLUSIONS: NG tube feeding appears to be effective and safe for acute pediatric pancreatitis compared with NJ tube feeding. In addition, high qualified, large sample sized, randomized controlled trials in pediatric population are needed.

BACKGROUND: Capsule endoscopy is a novel non-invasive method for visualization of the entire small bowel. The diagnostic yield of capsule endoscopy depends on the quality of visualization of the small bowel mucosa and its complete passage through the small bowel. To date, there is no standardized protocol for bowel preparation before capsule endoscopy. The addition of simethicone in the bowel preparation for the purpose of reducing air bubbles in the intestinal lumen had only been studied by a few investigators. METHODS: Sixty-four participants were randomly divided into two groups to receive a bowel preparation of polyethylene glycol (PEG) solution (Group 1) and both PEG solution and simethicone (Group 2). The PEG solution and simethicone were taken the night before and 20 min prior to capsule endoscopy, respectively. Frames taken in the small intestine were examined and scored for luminal bubbles by two professional capsule endoscopists. Gastric emptying time and small bowel transit time were also recorded. RESULTS: Simethicone significantly reduced luminal bubbles both in the proximal and distal small intestines. The mean time proportions with slight bubbles in the proximal and distal intestines in Group 2 were 97.1% and 99.0%, respectively, compared with 67.2% (P<0.001) and 68.8% (P<0.001) in Group 1. Simethicone had no effect on mean gastric emptying time, 32.08 min in Group 2 compared with 30.88 min in Group 1 (P=0.868), but it did increase mean small intestinal transit time from 227.28 to 281.84 min (P=0.003). CONCLUSION: Bowel preparation with both PEG and simethicone significantly reduced bubbles in the intestinal lumen and improved the visualization of the small bowel by capsule endoscopy without any side effects observed.

AIM: To analyze clinical differences between monogenic and nonmonogenic very-early-onset inflammatory bowel disease (VEO-IBD) and to characterize monogenic IBD phenotypically and genotypically via genetic testing. METHODS: A retrospective analysis of children aged 0 to 6 years diagnosed with VEO-IBD in a tertiary hospital in southern China from 2005 to 2017 was performed. Clinical data for VEO-IBD patients were collected, and genetic characteristics were analyzed using whole exome sequencing or target gene panel sequencing. RESULTS: A total of 54 VEO-IBD patients were included in this study. A diagnosis of Crohn's disease (CD) or CD-like intestinal manifestations accounted for 72.2% of the VEO-IBD cases. Nine patients (16.7%) were identified by genetic testing as having monogenic IBD. The median age of diagnosis in the monogenic group was younger than that of the nonmonogenic IBD group, at 18 mo (interquartile range (IQR): 4 to 78) and 43.5 mo (IQR: 3 to 173), respectively; the P-value was 0.021. The incidence of perianal disease in the monogenic group was higher than that in the nonmonogenic group (P = 0.001). However, there were no significant differences between weight-for-age and height-for-age Z-scores between the two groups, and similar laboratory results were obtained for the two groups. Five patients were found to have IL10 receptor mutation, two patients had chronic granulomatous disease, one patient had common variable immunodeficiency disease, and one patient had X-linked inhibitor of apoptosis protein deficiency. CONCLUSION: A high proportion of monogenic IBD was observed in the VEO-IBD group, especially with disease onset before the age of 6 mo. Monogenic IBD and nonmonogenic IBD exhibited similar clinical features. Furthermore, next-generation sequencing played an important role in the diagnosis of monogenic IBD, and IL10 receptor mutation was predominant in this cohort.

BACKGROUND: The guidelines addressed the evidence-based indications for the management of children with acute infectious diarrhea in Chinese pediatric population. DATA SOURCES: The experts group of evidence development put forward clinical problems, collects evidence, forms preliminary recommendations, and then uses open-ended discussions to form recommendations. The literature review was done for developing this guideline in databases including PubMed, Cochrane, EMBASE, China Biomedical Database, and Chinese Journal Full-text Database up to June 2013. Search the topic "acute diarrhea" or "enteritis" and "adolescent" or "child" or "Pediatric patient" or "Baby" or "Infant". RESULTS: For the treatment of mild, moderate dehydration, hypotonic oral rehydration solutions (ORS) are strongly recommended. Intravenous (IV) rehydration is recommended for severe dehydration, with a mixture of alkali-containing dextrose sodium solution. Nasogastric feeding tube rehydration is used for children with severe dehydration without IV infusion conditions with ORS solution. Regular feeding should resume as soon as possible after oral rehydration or IV rehydration. The lactose-free diet can shorten the diarrhea duration. Zinc supplements are recommended in children with acute infectious diarrhea. Saccharomyces boulardii and Lactobacillus Rhamnus are recommended to be used in acute watery diarrhea. Saccharomyces boulardii is recommended in children with antibiotic-associated diarrhea as well. Montmorillonite and Racecadotril (acetorphan) can improve the symptoms of diarrhea or shorten the course of acute watery diarrhea. Antibiotics are recommended with dysenteric-like diarrhea, suspected cholera with severe dehydration, immunodeficiency, and premature delivery children with chronic underlying disease; otherwise, antibiotics are not recommended. CONCLUSION: The principles of the most controversial treatments with of acute infectious disease are reaching to a consensus in China.

Intestinal lymphangiectasia (IL) is a rare disease characterized by dilated lymphatic vessles in the intestinal wall and small bowel mesentery which induce loss of protein and lymphocytes into bowel lumen. Because it most often occurs in the intestine and cannot be detected by upper gastroendoscopy or colonoscopy, and the value of common image examinations such as X-ray and computerized tomography (CT) are limited, the diagnosis of IL is difficult, usually needing the help of surgery. Capsule endoscopy is useful in diagnosing intestinal diseases, such as IL. We here report a case of IL in a female patient who was admitted for the complaint of recurrent edema accompanied with diarrhea and abdominal pain over the last twenty years, and aggravated ten days ago. She was diagnosed by M2A capsule endoscopy as a primary IL and confirmed by surgical and pathological examination.

Mycoplasma pneumoniae (M. pneumoniae) infection can cause community acquired pneumonia in children. A real-time method of simultaneous amplification and testing of M. pneumoniae (SAT-MP) was developed to diagnose M. pneumoniae targeting a region of the ribosomal RNA. The SAT-MP assay can accurately identify M. pneumoniae with a detection range from 101 to 107 CFU/ml. In this study, the specimens from 315 children with pneumonia were collected and analyzed by SAT-MP in parallel with real-time PCR method and IgM ELISA assay. The positive rates of these specimens examined by SAT-MP assay, real-time PCR method and IgM ELISA assay were 16.51%, 15.56% and 12.70% respectively. While there was statistical significance (p = 0.04) between SAT-MP assay and IgM ELISA assay, no statistical significance (p = 0.25) was found between SAT-MP assay and real-time PCR method and these two methods had high consistency (kappa value = 0.97). These findings indicate that the newly developed SAT-MP assay is a rapid, sensitive and specific method for identifying M. pneumoniae with potential clinical application in the early diagnosis of M. pneumoniae infection.

AIM: To investigate the diagnostic yield of capsule endoscopy (CE) in patients with obscure gastrointestinal bleeding (OGIB), and to determine whether the yield was affected by different bleeding status. METHODS: Three hundred and nine consecutive patients (all with recent negative gastric and colonic endoscopy results) were investigated with CE; 49 cases with massive bleeding and 260 cases with chronic recurrent overt bleeding. Data regarding OGIB were obtained by retrospective chart review and review of an internal database of CE findings. RESULTS: Visualization of the entire small intestine was achieved in 81.88% (253/309) of cases. Clinically positive findings occurred in 53.72% (166/309) of cases. The positivity of the massive bleeding group was slightly higher than that of the chronic recurrent overt bleeding group but there was no significant difference (59.18% vs 52.69%, P > 0.05) between the two groups. Small intestinal tumors were the most common finding in the entire cohort, these accounted for 30% of clinically significant lesions. In the chronic recurrent overt bleeding group angioectasia incidence reached more than 29%, while in the massive bleeding group, small intestinal tumors were the most common finding at an incidence of over 51%. Increasing patient age was associated with positive diagnostic yield of CE and the findings of OGIB were different according to age range. Four cases were compromised due to the capsule remaining in the stomach during the entire test, and another patient underwent emergency surgery for massive bleeding. Therefore, the complication rate was 1.3%. CONCLUSION: In this study CE was proven to be a safe, comfortable, and effective procedure, with a high rate of accuracy for diagnosing OGIB.

Takayasu's arteritis (TA), also known as the "pulseless disease," is a chronic vasculitis of the aorta and aortic branches. TA with Crohn's disease is rare and has not been documented in China before. In this paper we report on a case of Takayasu's arteritis associated with concurrent Crohn's disease. A 17-year-old Chinese male developed upper limb sourness and a sensation of fatigue, and his upper limb pulses were absent. He was diagnosed with TA and underwent an axillary artery bypass with autologous great saphenous vein on the left subclavian artery. After the surgery, he regained the normal blood pressure. This patient also had years of diarrhea and developed an anal canal ulcer, and was diagnosed with inflammatory bowel disease and ulcerative colitis before. Five months after the TA surgery, he was hospitalized for severe stomachache and diarrhea and was finally diagnosed with Crohn's disease. The possible pathophysiological mechanisms responsible for concurrent existence of TA and Crohn's disease may be associated with immune disorders, especially autoimmunity.
