ABSTRACT
Objective:To analyze the changes of common pathogens of viral diarrhea in children during the COVID-19 epidemic.Methods:A retrospective analysis was performed on children with acute diarrhea treated in Children’s Hospital affiliated to Zhejiang University School of Medicine from 2019 April to 2019 December(before COVID-19, n=407)and 2020 April to 2020 December (during COVID-19, n=645). Children were further divided into 1-6 months, >6 months-2 years, >2-5 years age groups. Detection rates of norovirus GI (NOVI), norovirus GⅡ (NOVⅡ), rotavirus A (ROVA), rotavirus C (ROVC), intestinal adenovirus (EADV), sapovirus (SAV) and astrovirus (ASV) in different age groups and seasons before and during COVID-19 were compared by χ2 or Fisher exact test. Results:The total detection rates of diarrhea-causing viruses among age groups were significantly higher before COVID-19 than those during COVID-19( χ2=8.43, 38.22 and 9.23, all P<0.05). The detection rates of NOVⅡ and EADV in infants aged 1-6 months and >6 months-2 years were decreased during the period of COVID-19 epidemic( χNOVⅡ2 =36.87 and 17.77, both P<0.001, χEADV2 =9.08, P=0.014 and 0.003); the detection rates of NOVⅡ in children aged 2-5 years was decreased during the period of COVID-19 epidemic( χ2=3.96, P=0.047); the detection rates of other diarrhea-causing viruses were not decreased during the period of COVID-19 epidemic(all P>0.05). The detection rates of diarrhea-causing viruses among 4-6 months, 7-9 months and 10-12 months were higher during the period of COVID-19 epidemic( χ2=11.62, 65.41 and 27.80, all P<0.001). Conclusion:After the outbreak of COVID-19, the detection rate of common pathogens of viral diarrhea in children is decreased, especially NOVⅡ and EADV, which may be related to the measures in response to major public health events in Zhejiang Province.
ABSTRACT
Objective@#To evaluate the effectiveness of enteral nutrition in children with accidental upper gastrointestinal injury.@*Methods@#The medical records of 128 patients with mechanical or chemical gastrointestinal mucosal injury, who were hospitalized in Department of Gastroenterology, Children's Hospital of Zhejiang University School of Medicine from January 1, 2011 to December 30, 2017, were collected. All cases were treated with enteral nutrition. The clinical features and etiologies were retrospectively analyzed. Weight-for-age Z score and lab findings including white blood cells, C-reactive protein, neutrophils, albumin, prealbumin, urea nitrogen and hemoglobin before and after treatment were extracted. The clinical characteristics, the duration of enteral nutrition and gastrointestinal mucosal healing between different etiologies were further analyzed. Normal distribution variables and categorized variables were compared with t test and χ2 test respectively, and abnormal distribution data was compared with Wilcoxon test.@*Results@#Among all the cases, 77 were males and 51 were females. The average age was (29±22) months. The mean duration of hospitalization and enteral nutrition were (11±7)d and (27±20)d respectively. Vomiting was the most common clinical presentation (72 cases, 56.3%). In 79 cases the problems were caused by mechanical injury, among which coins were most commonly seen. The rest 49 cases were caused by chemical injury. However, the duration of hospitalization ((13±8) d vs. (10±6)d, t=-3.089, P=0.002) and enteral nutrition ((39±22) vs. (19±14) d, t=-5.365, P=0.000) were longer in children with chemical injury than those with mechanical injury. A total of 112 cases got complete blood count and C-reactive protein both before and after enteral nutrition. Inflammatory markers, including leukocytes ((7.7±2.7) ×109/L vs. (13.7±5.0) ×109/L, t=12.244, P <0.05), neutrophils ((3.4±1.9)×109/L vs. (9.4±4.6) ×109/L, t=13.655, P<0.05), and C-reactive proteins (5.0(3.0,7.8) vs. 13.5(6.0,40.5) mg/L, Z=7.776, P <0.05) were significantly decreased. The nutritional markers, including the weight-for-age z score (-0.1 ± 1.0 vs. 0.0 ± 1.0, t=-2.622, P=0.010) and the prealbumin (0.1 ± 0.1 vs. 0.2 ± 0.0 g/L, t=-3.671, P=0.001) were significantly increased. Fifty-five (82.1%) children in mechanical injury group recovered in 4 weeks, while 27 (79.4%) children in chemical injury group recovered in 7 weeks.@*Conclusion@#Enteral nutrition can provide adequate nutritional requirements for children with upper gastrointestinal injury, and may help to decrease imflammation and improve mucosal healing.
ABSTRACT
Objective@#To explore the clinical features and complications of foreign bodies in the upper gastrointestinal tract in children and to investigate the effectiveness of endoscopic management.@*Methods@#Data of patients with foreign bodies in upper gastrointestinal tract were collected retrospectively at Endoscopy Center, the Children's Hospital, Zhejiang University School of Medicine, from January 2011 to December 2016. Clinical characteristics, the types of foreign bodies, the location and duration of foreign body impaction were summarized. The risk factors of complications and endoscopic removal failure were analyzed by using Logistic regression analysis.@*Results@#A total of 1 334 patients (825 males and 509 females) were enrolled. The median age was 2.5 years, with a range from 0.25 to 15 years and peak age 1-3 years. Twenty patients had esophageal diseases. The most common foreign body ingested was coin (n=964, 72.3%). Foreign bodies were most commonly located in the esophagus (n=1 002, 75.1%), especially in the upper esophagus (n=857, 85.5%). The duration of foreign body impaction ranged from 3 hours to 5 years. Among 1 334 patients, 252 patients (18.9%) developed complications, including ulcers (n=101, 40.0%) and perforations(n=13, 5.2%). The success rate of endoscopic removal was 96.6% (n=1 288). By Logistic regression analysis, sharp foreign body ingestion (OR=6.893, 95%CI: 4.421-10.746) , esophageal impaction (OR=5.253, 95%CI:3.352-8.233) and foreign body impaction longer than 24 hours (OR=4.336, 95%CI:3.091-6.082) were risk factors of complications. Sharp foreign body ingestion was the risk factor of endoscopic failure (OR=5.372, 95%CI:2.773-10.406) .@*Conclusions@#Coin is the most common foreign body in upper gastrointestinal tract. Sharp foreign bodies impacted in the esophagus over 24 hours increase the risk of complications. Endoscopic removal of foreign bodies from the upper gastrointestinal tract in children has a high success rate. Sharp foreign body ingestion increases the risk of failure in endoscopic removing.
ABSTRACT
Objective@#To analyze the clinical characteristics of X-linked inhibitor of apoptosis (XIAP) deficient patients with clinical manifestation of Crohn's disease.@*Methods@#Clinical manifestations, laboratory investigations, genetic testing and therapeutic interventions of one case of XIAP deficiency who was admitted to Department of Gastroenterology in Children's Hospital, Zhejiang University School of Medicine in May 2016 were summarized. PubMed and Chinese database for articles published from January 2016 to June 2017 were searched using the key words of'Crohn's disease’and'XIAP’, and the relevant literature was reviewed.@*Results@#The case we reported was a 6-year-1-month-old boy with recurrent bloody stool for 2 months, and abdominal pain with fever for 2 weeks. The patient had a past history of hemophagocytic lymphohistiocytosis (HLH) and epilepsy in the past one year. Complete blood cell count showed mild anemia (Hb108 g/L). The patient had an elevated high-sensitivity C reactive protein (86 mg/L) and erythrocyte sedimentation rate (46 mm/1h) . White blood cells, pus cells and red blood cells were found on routine stool examination. Biochemical panel showed hypoalbuminemia (25.2 g/L) , elevated transaminase (alanine aminotransferase 175 U/L, aspartate transaminase 229 U/L) , hypertriglyceridemia (4.41 mmol/L) , and hyperferritinemia (>1 650.0 μg/L) . Magnetic resonance enterography revealed the intestinal wall thickening and increased enhancement in parts of illeum and colon. Capsule endoscopy revealed multiple ulcers in jejunum. Colonoscopy showed multiple ulcers in colon and the pathological examination revealed chronic inflammation in mucosa of terminal ileum and colon, which was combined with partial necrosis and ulceration. Some phagocytes were seen in bone marrow smears. The patient was given multiple diagnoses, including hemophagocytic lymphohistiocytosis, Crohn's disease, sepsis, epilepsy, severe malnutrition, and hypoproteinemia. The pediatric Crohn's disease activity index (PCDAI) was 37.5. Genetic testing identified a hemizygotic mutation of c.910G>T chrX:123022501 p.G304X in XIAP. The parents had no such mutation. The patient showed response to infliximab with oral intake of mercaptopurine and corticosteroids, and had remission with PCDAI of 0. There were 9 relevant articles (Chinese 0 English 9), which showed 33.3% XIAP deficient patients manifested with inflammatory bowel disease(IBD), who might have other manifestations such as hemophagocytic lymphohistiocytosis or splenomegaly simultaneously or sequentially. Those patients showed poor response to monotherapy.@*Conclusion@#XIAP deficient patients have various clinical manifestations. Genetic testing is important to those male pediatric IBD patients who have the complicated symptoms or little response to standard therapy.
ABSTRACT
<p><b>OBJECTIVE</b>To explore the value of magnetic resonance enterography (MRE) for diagnosis of small intestinal diseases in children.</p><p><b>METHOD</b>A total of 92 children who received MRE from July 2009 to January 2014 were included into this study. The clinical value of MRE in children was evaluated by describing the image presentation of MRE based on clinical diagnosis.</p><p><b>RESULT</b>All the 92 cases (average age was nine year and one month, among whom 61 were boys, and 31 were girls) received MRE examination with good tolerance and had no complications. Eleven cases (12%) did not show good distension of small bowel loop during MRE and could not evaluate the bowel wall pathologies correctly. A total of 66 cases (72%) showed pathological MRE images. All patients with Crohn's disease showed pathological gut and 53% (16/30) showed extramural changes with MRE, 97% (29/30) showed colon lesions with colonoscopy, 73% (20/22) showed small intestine lesions with capsule endoscopy. All patients with intestinal obstruction (7 cases) showed abnormal gut distension, 4 of whom showed obstruction point. Five patients with small intestinal neoplasms showed the mass with MRE. One of the patients with intestinal tuberculosis showed enlarged lymph nodes with ring strengthening. Nine cases with eosinophilic gastroenteritis (75%) and 1 case of gastrointestinal bleeding showed increased contrast enhancement for small bowel. The main finding of MRE were abnormal wall thickening and enhancement, gut stricture, bowel expansion, etc.</p><p><b>CONCLUSION</b>MRE for children was safe and reliable. It can be a suitable method for determining the location and extent of gut for small intestinal diseases, especially suitable for Crohn's disease in children.</p>

<p><b>OBJECTIVE</b>To investigate the efficacy of infliximab versus corticosteroids in achieving clinical remission in pediatric patients with Crohn's disease in China.</p><p><b>METHOD</b>Data of all newly diagnosed active Crohn's disease pediatric cases seen from June 2009 to December 2013 in Children's Hospital, Zhejiang University School of Medicine were retrospectively recorded and reviewed.</p><p><b>INCLUSION CRITERIA</b>the age of the children was less than 18 years; pediatric Crohn's disease activity index (PCDAI) was more than 10; infliximab or corticosteroids were used for inducing remission; infliximab, immunosuppressive medications or mesalamine was prescribed for maintaining remission. Patients in steroids group were followed up for more than 1 year. The enrolled patients were divided into two groups: infliximab group and steroids group. Clinical data, laboratory findings and side effects of the medications were collected at week 2, 4, 12, 24 and 48. PCDAI and Crohn's disease endoscopic index score (CDEIS) were calculated. Clinical response rate, clinical remission rate, relapse rate, mucosal healing and growth were evaluated.</p><p><b>RESULT</b>Eleven children received infliximab therapy and 11 subjects received corticosteroids. In Infliximab group, 6, 5 and 7 patients were in clinical remission at week 2, 4, and 8, while so were 6, 9, and 9 patients in steroids group. The difference was not statistically significant (χ² = 0.00, 3.14, 0.92, P > 0.05). In infliximab group, 8, 8, and 11 patients were in clinical remission at week 2, 4, and 8, so were 8, 9, and 9 patients in steroids group. The difference was not statistically significant (χ² = 0.00,0.26, 2.20, P > 0.05). When compared with data at baseline, significant decreases were observed in the median PCDAI between the two groups at week 2, 4, and 8 (all P < 0.05). But there were no significant differences between two groups at week 2, 4, and 8 (all P > 0.05). At week 12, 24 and 48, 8/11, 7/8, 3/5 cases on infliximab versus 7/11, 9/11, 8/11 cases on steroids maintained remission. There was no significant differences between the two groups (all P > 0.05). In 7 patients and 9 patients remission was successfully induced at week 8. The relapse rate was similar at week 12, 24, and 48 (χ² = 0.83, 0.09, 1.00, all P > 0.05). Height for age Z score in infliximab group was significantly higher than that in steroids group at week 24 (P < 0.05). Body mass index Z score between the two groups at week 8, 24, and 48 were not statistically significant (all P > 0.05). Of the children treated with infliximab, 3 developed side effects. All the children treated with steroids got Cushing's syndrome.</p><p><b>CONCLUSION</b>In children with Crohn's disease, infliximab therapy is as effective as corticosteroids to induce remission.Less side effects were observed with infliximab therapy compared with immunosuppressive medication and mesalamine.</p>
