RESUMEN
Objective:To investigate the clinical phenotype and prognosis among different genotypes of progressive familial intrahepatic cholestasis(PFIC) by cases analysis.Methods:The PFIC cases diagnosed at Beijing Children′s Hospital from 2015 to 2022 were collected, and the clinical phenotypic characteristics, treatment and prognosis were compared and analyzed.Results:A total of 628 cases of cholestatic liver disease were diagnosed, and 26 cases of PFIC were found, accounting for 4.1%.The number of PFIC 2 were the most, 14(53.8%)cases; three(11.5%) cases were PFIC 1; five(19.2%)cases were PFIC 3; while two(7.7%) cases were PFIC 4 and PFIC 6, respectively, and there was no case of PFIC 5.Type 1, 2, 4, and 6 had early onset ages(2 days to 21 months), while type 3 had a wide range of onset ages(8 to 145 months). The symptoms included jaundice(96.2%), pruritus(42.3%), and mucosal bleeding(15.4%). All three cases of type 1 had extrahepatic manifestations of diarrhea and malnutrition.Two cases of type 3 were found to have end-stage liver disease.Cases of PFIC 3 had increased serum γ-glutamyltransferase(97.2-439.5 U/L), while those of other types were normal.The bile acids were all increased(10.1-599.6 μmol/L). Abdominal ultrasound mainly showed liver enlargement(80.8%)and enhanced echogenicity of liver parenchyma(73.1%), enlargement of the spleen(61.5%). Ultrasound liver elastography ranged from 6.3 kPa to 23.1 kPa, there were 21(80.8%) cases ≥9 kPa.Among 26 cases, one case was lost to follow-up, and 11 cases were effective by oral medication alone.Fourteen children were still suffering from relapse or progress after drug treatment: four cases received liver transplantation (three cases had a good prognosis and one case died), two cases received biliary drainage, six cases were still taking drugs orally, and two cases died without active intervention in disease progress.Conclusion:Type 2 is the most common type in PFIC.The onset of most cases is in infancy.Jaundice, pruritus and hepatosplenomegaly are common clinical manifestations, and extrahepatic manifestations can be seen in type 1 cases.Type 3 cases can start with end-stage liver disease.Bile acid of all cases are increased.Except for type 3, the serum γ-glutamyltransferase of cases are normal.Oral medication has certain effects on some cases, but more than half progress, and some need biliary diversion or liver transplantation.
RESUMEN
Objective:To investigate the expression and clinical significance of vitamin D receptor (VDR) and human β-defensin-2(HBD2) in children with Helicobacter pylori (Hp) infection and gastritis.Methods:Eighty-one children who were hospitalized in the Department of Gastroenterology at Beijing Children′s Hospital from January 2021 to June 2023 and underwent endoscopic examination were collected.They were divided into Hp infection group and non-Hp infection group according to whether they were infected with Hp.The expression levels of VDR and HBD2 between two groups, and the correlation between VDR, HBD2 expression levels and gastritis were compared and analyzed.Results:Among 81 cases, 48 cases were Hp positive, including 24 males and 24 females, with an average age of (11.4±2.7) years; 33 cases were Hp negative, including 14 males and 19 females, with an average age of (11.3±2.6) years.There were no significant differences in sex and age between two groups ( P>0.05). The positive rates of VDR and HBD2 expression in gastric mucosa of children with Hp infection were higher than those of children without Hp infection, and the differences were statistically significant (87.5% vs.39.4%, 79.2% vs.63.6%, all P<0.05). The expressions of VDR and HBD2 had no correlation with age and sex ( P>0.05). The expressions of VDR and HBD2 were positively correlated with granular degeneration of gastric mucosa ( r=0.384, P<0.001; r=0.258, P=0.020). The expression of VDR was positively correlated with the degree of gastric inflammation ( r=0.365, P=0.001), while the expression of HBD2 was not correlated with the degree of gastric inflammation ( P>0.05). Conclusion:The expression levels of VDR and HBD2 in gastric mucosa of children infected with Hp are increased.The expression level of VDR is correlated with the degree of gastritis and the granular degeneration of gastric mucosa.The expression level of HBD2 is correlated with the granular degeneration of gastric mucosa.But there is no correlation between the level of HBD2 expression and the degree of gastritis.
RESUMEN
Objective:To investigate the correlation between the waiting time for radiotherapy after induction chemotherapy and the prognosis of locally intermediate and advanced nasopharyngeal carcinoma, as well as its optimal time.Methods:Retrospective analysis of 101 patients with locally intermediate and advanced nasopharyngeal carcinoma admitted to the Fifth Affiliated Hospital of Sun Yat-sen University from 2017 to 2020 was performed. All patients received at least 2 courses of induction chemotherapy followed by radical radiotherapy. The waiting time for radiotherapy was defined as the time from the end of induction chemotherapy to the start of the first radiotherapy. The relationship between waiting time for radiotherapy and other factors (age, gender and stage, etc.) with progression-free survival (PFS), local recurrence-free survival (LRFS) and distant metastasis-free survival (DMFS) was analyzed through Cox model. The median waiting time for radiotherapy with 3 weeks was used as the boundary, and all patients were divided into ≤3 weeks and>3 weeks groups. The PFS, LRFS and DMFS between two groups were compared using Kaplan-Meier survival analysis. P<0.05 was considered as statistical significance. Results:Cox-regression analysis showed that the waiting time was correlated with PFS, LRFS, and DMFS (all P<0.05). Kaplan-Meier survival analysis suggested that the PFS, LRFS and DMFS in the ≤3 weeks group were significantly better than those in the >3 weeks group (all P<0.05). Under the premises of the T 3 stage, N 2 stage and the increased EB virus DNA replication levels before treatment, the PFS, LRFS and DMFS in the ≤3 weeks group were significantly better than those in the >3 weeks group (all P<0.05). Conclusions:The waiting time for radiotherapy is one of the factors affecting clinical prognosis of locally intermediate and advanced nasopharyngeal carcinoma. The earlier the time, the better the prognosis. Radiotherapy should be delivered within 3 weeks.
RESUMEN
Cow′s milk protein allergy (CMPA) is one of the most common presentations of food allergy seen in early childhood.It is an abnormal immune response caused by cow′s milk protein.CMPA can be clinically subdivided into either immediate-onset IgE mediated or delayed onset non-IgE mediated, or both.At present, concerns regarding the early and timely diagnosis of CMPA have been high-lighted over the years and there are many expert consensus on CMPA in China, but these consensus did not distinguish IgE mediated or non-IgE mediated CMPA.In view of the obvious clinical differences between the two type of CMPA and non-IgE mediated CMPA is more common in infancy, experts focus on pediatric gastroenterology, allergy/immunology, dermatology, nutrition and child healthcare convened by the Allergy Prevention and Control Professional Committee of Chinese Preventive Medicine Association present this guideline to help practitioners in primary care settings to early recognize and make suitable management of non-IgE mediated CMPA in China.The guideline incorporates the cutting-edge international guidance and the actual situation of Chinese children describing in detail the types, clinical features, diagnosis and nutritional intervention of non-IgE mediated CMPA.There are 42 recommendations in 7 categories in total referring to the common questions related to non-IgE mediated CMPA.
RESUMEN
Objective:To compare the efficacy of combination therapy on cyclic vomiting syndrome(CVS)in children, and improve the efficacy of CVS treatment in the future.Methods:This study retrospectively analyzed patients′ medical records of CVS, which were admitted to Digestive Department of Beijing Children′s Hospital from 2012 to 2019.The treatment regimen was A(Cyproheptadine+ Doxepin+ Valproate), B(Propranolol+ Cyproheptadine), or C(Propranolol+ Amitriptyline). Meanwhile, the patients should take drugs more than three months.The clinical data of 42 cases were analyzed retrospectively, and the treatment effect after discharge was followed up by telephone until October, 2020.Results:Among the 42 cases, 17 were male and 25 were female, whose mean age of onset was (4.65±3.23) years, and the age of diagnosis was (6.79±3.58) years.The main accompanied symptoms were abdominal pain and upper gastrointestinal bleeding.Forty-two patients were moderate/severe CVS.The regimens A, B and C were observed in 7, 11, and 24 patients, respectively.The age at improvement was(8.17±4.12)years.The course of treatment was(1.37±0.96)years.The age at follow-up was(10.32±4.03)years.During the 1-year follow-up, 35 cases were effective, and the efficiency was 83.3%.Among them, 23 cases had no paroxysmal vomiting and 7 cases had no effect.There was no significant difference in therapy effects among group A, B and C. Between the effective group and non-effective group, there were statistical differences in the personal history of hiatus hernia( P=0.024), the weight at follow-up ( P=0.042), and the course of medication( P=0.020). Conclusion:The combination regimen has a higher effective rate in the treatment of CVS.There was no significant difference among the three regimens in the treatment of CVS.For children with refractory CVS, who can not be treated with combination therapy, individualized therapy should be further developed.

RESUMEN
Objective:To summarize the clinical and genetic characteristics of catecholaminergic polymorphic ventricular tachycardia (CPVT) in children caused by CASQ2 gene variants. Methods:The clinical data of 8 children (4 males and females, respectively) with CPVT caused by CASQ2 gene variants admitted to Beijing Children′s Hospital, Capital Medical University from January 2017 to November 2018 were retrospectively analyzed.The targeted next generation sequencing was employed to identify CASQ2 variants and Sanger sequencing was conducted to conform the candidate variants and determine the parental origin. Results:As for 8 children in this study, the average age of onset was 6.4 years, the mean age at diagnosis was 9.4 years, and the average interval from onset to diagnosis was 3 years.Only 2 cases had clearly diagnosis at onset, other 6 cases had a delay to diagnosis and 3 cases of them were diagnosed at other hospitals as having epilepsy and did not respond to anti-epileptic therapy.During physical activity and/or emotional stress, 8 cases presented with recurrent syncope and were able to regain consciousness after a few minutes.They had no a history of sudden cardiac death or family history.There was no abnormality on resting electrocardiogram during the paroxysmal interval in 6 cases and mild sinus bradycardia in 2 cases.Typical bidirectional ventricular tachycardia (VT) and/or polymorphic VT were detected in 8/8 cases and 5/5 cases, respectively, based on Holter electrocardiography and cardiac stress test.The CASQ2 gene variant was found in all children, with 6 cases carrying compound heterozygous variants and 2 cases carrying homozygous variants.A total of 9 different CASQ2 variants were detected in 8 cases, of which 5 had not been previously reported.According to the family-line verification, all of them had a familial variant, with no novel variants.All 8 cases were treated orally with β-blockers, with asymptomatically recurrent episodes, with a mean follow-up of 1.5 years, during which implantable cardioverter defibrillation was performed in 1 case owing to severe sinus bradycardia.There was no death case among them. Conclusions:CPVT with CASQ2 variants is characterized by early onset before preschool age, recurrent syncope after exercise or emotional stress and bidirectional/polymorphic VT.Early diagnosis of CPVT remains challenging due to delayed diagnosis or misdiagnosis.Treatment with β-blockers can achieve favorable effectiveness and safety.Five novel variants in this study would further expand the database of CASQ2 genes.
RESUMEN
Objective:To summarize and analyze the clinical features of food protein-induced enterocolitis syndrome (FPIES).Methods:The medical history and follow-up data of 5 children with FPIES diagnosed in Department of Gastroenterology, Beijing Children′s Hospital of Capital Medical University from July 2018 to September 2019 were collected, and their clinical characteristics were summarized and analyzed.Results:Five children with FPIES were all infants, including 3 females and 2 males.Before the onset of the disease, the cases visited multiple departments and the average number of visits before diagnosis was 3.There were 4 cases of milk protein allergy and 1 case of egg white allergy.The patients had acute vomiting [5 cases (100%)], diarrhea [4 cases (80%)], early shock symptoms [5 cases (100%)], transient fever [2 cases (40%)]. Hematogenous leukocytes were increased in 3 cases (60%), C-reactive protein was increased in 1 case (20%), faecal leukocytes(+ )[2 cases (40%)], occult blood (+ ) [1 case (20%)]. Four cases were tested for food allergen specific IgE, of which 2 cases (40%) were positive for milk protein.After avoiding allergens, 3 patients (60%) needed intravenous rehydration treatment and 2 cases (40%) received oral rehydration treatment.The above 5 cases recovered quickly.Three patients (60%) used antibiotics.Four cases (80%) of the first-degree relatives of FPIES had a clear history of allergy.Families of children with FPIES had low awareness of the disease before the diagnosis was made, and the allergens were strictly avoided according to the doctor′s instructions after the diagnosis was made.Similar allergic reactions did not occur again, and complementary foods were gradua-lly added under the guidance of the doctor.Two patients had multiple food allergies.The body weight and length of 2 children with growth retardation were catching up with each other.Conclusions:FPIES is a serious food allergy related gastrointestinal disease which is easy to be misdiagnosed clinically.The diagnosis requires a combination of the family and personal allergy history, diet records, the characteristic performance of disease onset, the effect of diet avoi-dance and the necessary differential diagnosis.The long-term management and monitoring after diagnosis is also very important.

Objective:To summarize clinical and genetic features of infantile-onset inflammatory bowel disease(IO-IBD) patients.Methods:The clinical data of 48 IO-IBD patients from Beijing Children′s Hospital, Capital Medical University, including age of onset, family history, clinical manifestations and drug efficacy were retrospectively analyzed.Based on target gene panel, next generation sequencing (NGS) was performed for 43 patients, and further compared clinical features between gene mutation and non-gene mutation IO-IBD groups.Results:Among the 48 IO-IBD patients, 41 cases suffered from Crohn′s disease (CD) and 7 cases were ulcerative colitis (UC). The median age of onset was 2.00(0.24-6.00) months, and 45.8%(22/48 cases) of patients′ onset age was within 1 month.Diarrhea (48/48 cases, 100%), fever (45/48 cases, 93.8%) and hematochezia (37/48 cases, 77.1%) were the main clinical symptoms.Perianal lesions and rashes were common extraintestinal manifestations, accounting for 43.8%(21/48 cases) each.Among 41 CD patients, 73.2%(30/41 cases) had predominantly colonic disease (L2 type), and disease behavior was mainly nonstricturing and nonpenetrating (B1 type) (33/41 cases, 80.5%). Among 7 UC patients, 57.1%(4/7 cases) had predominantly pancolonic (E4 type). The surgical rate of the 48 IO-IBD patients was 12.5%(6/48 cases), the clinical remission rate was 50.0%(24/48 cases), and the mortality rate was 25.0%(12/48 cases). Among the 43 IO-IBD patients, 23 (23/43 cases, 53.5%) had meaningful gene mutations, of which 22 cases had mutations in interleukin-10 receptor A ( IL-10 RA) and 1 case with mutation in TTC37.A total of 11 mutation sites were detected in 22 patients with IL-10 RA mutations, including one novel mutation site c. 635G>C (p.R212P); 19 cases c. 301C>T (p.R101W) and 8 cases c. 537G>A (p.T179T) that were common mutation sites.Compared with non-gene mutation IO-IBD group, patients in gene mutation IO-IBD group had earlier onset age [0.3 (0.1-1.0) months vs.(6.27±5.64) months, P<0.001], higher proportion of malnutrition [14 cases(60.9%) vs.5 cases(25.0%), P=0.018], oral ulcers [14 cases(60.9%) vs. 30 cases(15.0%), P=0.006] and perianal lesions [17 cases(73.9%) vs.3 cases(15.0%), P<0.001], and the lower rate of clinical remission[7 cases(30.4%) vs.15 cases(75.0%), P=0.004]. Conclusions:IO-IBD patients had a high rate of monogenic mutation, and IL-10 RA gene mutation was the common mutation.IO-IBD patients developing with gene mutation were characterized by early age of onset, higher incidence of malnutrition, oral ulcers, perianal lesions, and the lower clinical remission rate.
RESUMEN
Objective To summarize the clinical data of the children with inflammatory bowel diseases (IBD),including Crohn's disease (CD) and ulcerative colitis (UC),and to analyze and compare the clinical features of very early-onset IBD (VEO-IBD) and late-onset IBD (LO-IBD).Methods A retrospective analysis of the clinical data of 184 cases of IBD hospitalized children diagnosed at Beijing Children's Hospital,Capital Medical University from January 2000 to December 2014.According to their ages of onset,the patients were divided into VEO-IBD group (＜6 years old) and LO-IBD group (6-16 years old);the patients with CD were divided into VEO-CD group (＜ 6 years old) and LO-CD group (6-16 years old);UC were divided into VEO-UC group (＜ 6 years old) and LO-UC group (6-16 years old).The clinical features among each group were analyzed and compared.Results A total of 184 IBD patients were included in the study,77 cases(41.8％) were VEO-IBD and 107 cases(58.2％) were LO-IBD.Comparison between VEO-CD group and LO-CD group indicated that abdominal pain was more common in LO-CD group (P ＜ 0.05),while diarrhea and hematochezia were more common in VEO-CD group (all P ＜ 0.05).In addition,comparison between VEO-UC group and LO-UC group indicated that abdominal pain was more common in LO-UC group(P ＜ 0.001),while diarrhea,fever,and oral ulcers were more common in VEO-UC group (all P ＜0.05).Both VEO-CD and LO-CD group were mainly ileocolonic[15/27 cases (55.6％),20/47 cases (42.6％)],non-narrow,non-penetrating [20/27 cases (74.1％),30/47 cases (63.8％)] and moderate-to-severe activity[23/27 cases(85.2％),37/47 cases (78.7％)].The incidence of perianal lesions in the VEO-CD group was as high as 51.9％ (14/27 cases),which was significantly higher than that in the LO-CD group (9/47 cases,19.1％) (P ＜ 0.05).Left-sided UC and severe UC were more common in VEO-UC group(all P ＜ 0.05),while pancolitis and mild UC were more common in LO-UC group (all P ＜ 0.05).The incidence of intestinal perforation in the VEO-UC group was significantly higher than that in the LO-UC group (P ＜0.05).The incidence of surgical rate,intestinal obstruction,and intestinal perforation in the LO-CD group were significantly higher than those in the LO-UC group (all P ＜ 0.05).Conclusions Compared between VEO-IBD and LO-IBD,VEO-IBD patients are more severe,with perianal lesions more common,and the incidence of intestinal perforation is higher.
RESUMEN
Objective@#To investigate the effect of the endoscopic selective varices devascularization (ESVD) for the esophageal gastric varices bleeding (EGVB) in children.@*Methods@#The clinical data of the patients diagnosed with EGVB and treated with ESVD from January 2018 to March 2018 were retrospectively analyzed. The effects, safety and complications of ESVD were evaluated.@*Results@#There were five patients (including 2 males and 3 females, age ranged from 4 to 7 years) in the study. No rebleeding was found at the first follow-up on one week post operation. Three patients were treated with the endo-therapy at the twice follow-up (3 months after surgery): 2 patients had ESVD again and 1 patient had resection under endoscopy due to stenosis caused by surgical scar. After the second procedure, there was no rebleeding but one patient had abdominal pain caused by mesenteric thrombosis, cured with low molecular weight heparin.@*Conclusion@#The ESVD for EGVB is safe and effective, but the long-term curative effect should be further studied.
RESUMEN
Objective@#To investigate the antibiotic resistance of Helicobacter pylori(Hp) isolates cultured from endoscopic gastric mucosal samples and influencing factors for antibiotic resistance in children.@*Methods@#From April 2013 to February 2016, Hp cultured from mucosa samples of the gastric antrum and the body of stomach was investigated in 246 patients with 13C breath test positive examined by gastroscopy.Resistance to Amoxicillin, Clarithromycin, Metronidazole, Tetracycline was tested for Hp by using E-test.The clinical data were collected from the patients, and the relationship among age, gender, endoscopic diagnosis, histological performance, eradication number factors and antibiotic resistance rate were analyzed.@*Results@#Of 246 specimens, 174 cases (70.7%) were positive.The overall antibiotic resistance rates of isolates obtained were 96.55% (168/174 cases), 57.47% (100/174 cases), 4.02% (7/174 cases), 1.15%(2/174 cases) with respect to Clarithromycin, Metronidazole, Tetracycline and Amoxicillin.An antibiotic resistance rate was 43.10% (75/174 strains), among which the Clarithromycin resistance rate was 93.33% (70/75 strains), and the Metronidazole resistance rate was 6.67% (5/75 strains). Double resistance rate was of 54.02%(94/174 strains), among which the resistances rate of Clarithromycin+ Metronidazole was 52.30%(91/94 strains), and the resistances rate of Clarithromycin+ Tetracycline was 1.72%(3/94 strains). Triple resistance rate of Clarithromycin+ Metronidazole+ Tetracycline was 1.15%(2/174 strains). Quadruple resistance rate of Clarithromycin+ Metronidazole+ Amoxicillin+ Tetracycline was 1.15%(2/174 strains). Factor analysis showed that the resistance rate of Clarithromycin in children who had failed in eradication therapy [98.7%(148/150 cases)] was higher than that in children who had not undergone eradication therapy [83.3%(20/24 cases)], and the difference was statistically significant(χ2=14.610, P<0.05). There was no significant difference in the relationship between Hp resistance to Metronidazole and Clarithromycin and the age, gender, endoscopic diagnosis and histological manifestations(all P>0.05).@*Conclusions@#Hp resistance rate to Clarithromycin, Metronidazole is very high in children, but it is relatively low to Amoxicillin and Tetracycline, and multiple antibiotic resistance is at high prevalence.

RESUMEN
Objective@#To summarize the clinical data including manifestations, diagnosis, treatment and prognosis of eosinophilic gastroenteritis (EGE) in children.@*Methods@#A retrospective analysis was performed in 71 patients with pathologically proven EGE at Beijing Children's Hospital Affiliated to Capital Medical University from January 2008 to January 2017. Their clinical manifestations, laboratory and imaging examinations, endoscopic findings, histopathological examinations, and treatment were collected and analyzed.@*Results@#Among 71 EGE cases, 47 (66%) cases were male and 24 (34%) cases were female, and the median age was 9.2 (0.2-16.5) years old. The main clinical manifestations included abdominal pain (76%, 54/71), vomiting (68%, 48/71), anorexia (54%, 38/71), weight loss (38%, 27/71), and diarrhea (37%, 26/71). There were 27 cases (38%) with a history of allergic diseases or family history. The median absolute value of eosinophil in peripheral blood of the 71 patients was 0.4 (0-36.8)×109/L, and 27 cases (38%) showed an increase in eosinophil counts. Serum IgE was measured in 52 patients (104.3 (3.4- 3 000.0)×103 U/L), and 30 patients (58%) showed an increase in serum IgE. A large number of eosinophils ((41.0±8.5)/HP) were found in 3 patients' ascites. The endoscopic examination of upper gastrointestinal tract revealed hyperemic edema in 62 cases (87%), plaque in 44 cases (62%), erosion in 17 cases (24%) and ulceration in 16 cases (23%). Histopathologically, in 8 cases (11%) the disease involved both stomach and duodeneum, in 21 cases (30%) involved stomach only, and in 37 cases (52%) involved duodeneum only. In addition, in 6 cases (8%) the disease involved esophagus and in 10 cases (14%) involved colorectum. Microscopically, eosinophil counts averaged 67/HP, 33/HP, 40/HP and 38/HP in esophageal, gastric, duodenal and colorectal mucosa respectively. A total of 34 cases were treated with glucocorticoid, and all these patients had alleviation of symptoms, which occurred within 14.9 days on average, but EGE recurred in 11 cases (32%).@*Conclusions@#The clinical symptoms and endoscopic findings of EGE are diverse and nonspecific. Histopathological examination of gastrointestinal mucosa is particularly important for the diagnosis. Glucocorticoid treatment is effective, but the patients with EGE are prone to relapse.
RESUMEN
Eosinophilic gastroenteritis is a relatively rare chronic gastrointestinal inflammatory disease in children,characterized by gastrointestinal eosinophil infiltration.Clinical manifestations due to infiltration of different sites and levels were diverse,endoscopic performance is often nonspecific,the diagnosis of eosinophilic gastroenteritis is mainly based on gastrointestinal symptoms,a large number of eosinophil histological infiltration,and exclude other diseases that cause eosinophil infiltration in gastrointestinal tissue.Treatments include diet therapy,glucocorticoids,anti-allergy drugs,immunomodulatory therapies.Although diet therapy and glucocorticoid treatment improve clinical symptoms in most children,long-term maintenance therapy and follow-up are often required to prevent recurrence.In children with serious complications,such as perforation and obstruction,may require surgery and other treatments.
RESUMEN
Objective To evaluate CYP2C19 genotypes distribution in children with Helicobacter pylori (Hp) infection and to know its correlation with gender,age,severity and frequency of clinical symptoms,pathological classification of gastric antral mucosa.Methods Antral mucosas of 214 Hp infection patients who were hospitalized at Beijing Children's Hospital of Capital Medical University from July 2013 to December 2015 were collected.Genotypes were determined by PCR-sequence specific primer method,which were classified as homozygous extensive metabolizer (HomEM),heterozygous extensive metabolizer (HetEM) and poor metabolizer (PM).The differences in CYP2C19 genotype distribution in gender,age,severity and frequency of clinical symptoms,pathological classification of gastric antral mucosa were analyzed.Results (1) Among 214 Hp infected children,the percentage of HomEM was 48.1％ (103/214 cases),HetEM was 46.3％ (99/214 cases),and PM was 5.6％ (12/214 cases).PM in the CYP2C19 infection patients was lower than that in the normal Han nationality in China,and the difference was statistically significant (P ＜ 0.05).(2)Among the 214 Hp infected patients,there were 124 males and 90 females,and their median age was 9 years and 9 months(ranged from 2 years and 8 months to 17 years and 11 months).There was no statistical difference in gender and age of CYP2C19 genotypes(all P ＞ 0.05).(3) There was no statistical difference in severity and frequency of clinical symptoms of CYP2C19 genotypes(all P ＞0.05).(4) In HomEM group,according to pathological classification of gastric mucosa,there were 14 cases of mild injury,36 cases of moderate injury and 53 cases of severe injury,respectively.In HetEM group,there were 17 cases of mild injury,29 cases of moderate injury and 53 cases of severe injury,respectively.In PM group,there were 2 cases of mild injury,3 cases of moderate injury and 7 cases of severe injury,respectively.There was no statistical difference in the pathological degree of inflammation changes in gastric antral mucosa of CYP2C19 genotypes(all P ＞0.05).(5)Thirty-five cases didn't receive treatment,78 cases received Hp eradication one time and failed,101 cases received no less than 2 times of unsuccessful Hp eradication.The number of Hp unsuccessful eradications were positively correlated with the degree of pathological inflammation changes (r =0.219,P ＜ 0.01).There was obvious difference between the number of Hp unsuccessful eradication and the pathological degree of inflammation changes in gastric antral mucosa (x2 =12.414,P ＜ 0.05).Conclusions There was no statistical difference in CYP2C19 genotypes distribution as for different gender,age,severity and frequency of clinical symptoms,pathological classification of gastric antral mucosa and CYP2C19 genotypes.The number of Hp unsuccessful eradication was positively correlated with the degree of pathological inflammation changes.
RESUMEN
Objective@#To analyze the clinical manifestations, diagnosis, treatment and prognosis of intestinal lymphangiectasia (IL) in children in order to improve the skills of diagnosis and treatment of IL.@*Method@#Clinical manifestations, laboratory findings, gastroscopic findings, histopathological examinations and lymphatic radionuclide imaging assessments were analyzed retrospectively among 47 IL patients who were hospitalized in the Gastroenterology Department of Beijing Children's Hospital Affiliated to Capital Medical University from June 2007 to December 2015. All patients were followed up by telephone. According to the various causes, the patients were divided into the primary intestinal lymphangiectasia (PIL) group and secondary IL group, and their clinical manifestations were compared by t test, Rank sum test or Chi-square test.@*Result@#In 47 IL patients, there were 38 children (81%) younger than 3 years old. There were 43 PIL patients (91%) and 4 secondary IL patients (9%). Between PIL and secondary IL, there were statistical differences in serum albumin (t=-3.950, P<0.005) , globulin(t=-2.850, P=0.007), age of onset(U=27.000, P=0.024), age at diagnosis(U=29.000, P=0.030) and course of disease(U=26.500, P=0.023), whereas there were no statistical differences in lymphocyte count, IgG, lymphatic radionuclide imaging, histopathology and gender(all P>0.05). Edema (44 cases, 94%), diarrhea (42 cases, 89%), accompanied with infection (35 cases, 74%) and ascites (30 cases, 64%) were the main clinical manifestations. In 47 IL patients, 45 patients were done gastroscopy and histopathological examinations, and there were 31 patients' histopathological examinations(69%) were positive. Forty patients were done lymphatic radionuclide imaging, and there was evidence of protein losing from gut via lymphatic radionuclide imaging in 39 patients(98%). Among 47 patients, 35 patients (74%) were followed up, 32 patients had good prognosis, 2 patient failed to show evidence of improvement, 1 patient died and no patient experienced a relapse till the end of the follow-up. In 35 patients, 28 patients were treated with medium chain triglycerides (MCT) dietary therapy, 26 patients showed improvement in symptoms, and 2 patients had no improvement. Among 35 patients with follow-up, there were 6 patients received surgical treatment, and their symptoms were improved.@*Conclusion@#PIL are the majority of IL in children younger than 3 years old. The main clinical manifestations are edema, diarrhea, accompanied with infection and ascites. For the patients without the evidence of lymphangiectasia from duodenum histopathological examination, further consideration of lymphatic radionuclide imaging, clinical manifestations, and laboratory studies are needed to make a final diagnosis. MCT dietary therapy is the cornerstone of IL medical management.
