Objective: In this study, we aimed to investigate the prevalence of low anterior resection syndrome (LARS) in patients who had survived for more than 5 years after sphincter-preserving surgery for rectal cancer and to analyze its relationship with postoperative time. Methods: This was a single-center, retrospective, cross-sectional study. The study cohort comprised patients who had survived for at least 5 years (60 months) after undergoing sphincter- preserving radical resection of pathologically diagnosed rectal adenocarcinoma within 15 cm of the anal verge in the Department of Gastrointestinal Surgery, Peking University People's Hospital from January 2005 to May 2016. Patients who had undergone local resection, had permanent stomas, recurrent intestinal infection, local recurrence, history of previous anorectal surgery, or long- term preoperative defecation disorders were excluded. A LARS questionnaire was administered by telephone interview, points being allocated for incontinence for flatus (0-7 points), incontinence for liquid stools (0-3 points), frequency of bowel movements (0-5 points), clustering of stools (0-11 points), and urgency (0-16 points). The patients were allocated to three groups based on these scores: no LARS (0-20 points), minor LARS (21-29 points), and major LARS (30-42 points). The prevalence of LARS and major LARS in patients who had survived more than 5 years after surgery, correlation between postoperative time and LARS score, and whether postoperative time was a risk factor for major LARS and LARS symptoms were analyzed. Results: The median follow-up time of the 160 patients who completed the telephone interview was 97 (60-193) months; 81 (50.6%) of them had LARS, comprising 34 (21.3%) with minor LARS and 47 (29.4%) with major LARS. Spearman correlation analysis showed no significant correlation between LARS score and postoperative time (correlation coefficient α=-0.016, P=0.832). Multivariate analysis identified anastomotic height (RR=0.850, P=0.022) and radiotherapy (RR=5.760, P<0.001) as independent risk factors for major LARS; whereas the postoperative time was not a significant risk factor (RR=1.003, P=0.598). The postoperative time was also not associated with LARS score rank and frequency of bowel movements, clustering, or urgency (P>0.05). However, the rates of incontinence for flatus (3/31, P=0.003) and incontinence for liquid stools (8/31, P=0.005) were lower in patients who had survived more than 10 years after surgery. Conclusions: Patients with rectal cancer who have survived more than 5 years after sphincter-preserving surgery still have a high prevalence of LARS. We found no evidence of major LARS symptoms resolving over time.

Objective: To explore disease characteristics of primary sclerosing cholangitis (PSC) and inflammatory bowel disease (IBD) and compare the differences between PSC with and without IBD. Methods: Study design was cross sectional. Forty-two patients with PSC who were admitted from January 2000 to January 2021 were included. We analyzed their demographic characteristics, clinical manifestations, concomitant diseases, auxiliary examination, and treatment. Results: The 42 patients were 11-74(43±18) years of age at diagnosis. The concordance rate of PSC with IBD was 33.3%, and the age at PSC with IBD diagnosis was 12-63(42±17) years. PSC patients with IBD had higher incidences of diarrhea and lower incidences of jaundice and fatigue than in those without IBD (all P<0.05). Alanine aminotransferase, total bilirubin, direct bilirubin, total bile acid and carbohydrate antigen 19-9 levels were higher in PSC patients without IBD than in those with IBD (all P<0.05). The positive rates for antinuclear antibodies and fecal occult blood were higher in PSC patients with IBD than in those without IBD (all P<0.05). Patients with PSC complicated with ulcerative colitis mainly experienced extensive colonic involvement. The proportion of 5-aminosalicylic acid and glucocorticoid application in PSC patients with IBD was significantly increased compared with that of PSC patients without IBD (P=0.025). Conclusions: The concordance rate of PSC with IBD is lower at Peking Union Medical College Hospital than in Western countries. Colonoscopy screening may benefit PSC patients with diarrhea or fecal occult blood-positive for early detection and diagnosis of IBD.

Objective: To investigate the clinical phenotypes and genotypic spectrum of exocrine pancreatic insufficiency in children with cystic fibrosis. Methods: This was a retrospective analysis of 12 children with cystic fibrosis who presented to Children's Hospital of Fudan University from December 2017 to December 2021. Clinical features, fecal elastase-1 level, genotype, diagnosis and treatment were systematically reviewed. Results: A total of 12 children, 7 males and 5 females, diagnosis aged 5.4 (2.0, 10.6) years, were recruited. Common clinical features included chronic cough in 12 cases, malnutrition in 7 cases, steatorrhea in 7 cases, bronchiectasis in 5 cases and electrolyte disturbance in 4 cases. Exocrine pancreatic insufficiency were diagnosed in 8 cases,the main clinical manifestations were steatorrhea in 7 cases, of which 5 cases started in infancy; 6 cases were complicated with malnutrition, including mild in 1 case, moderate in 2 cases and severe in 3 cases; 3 cases had abdominal distension; 2 cases had intermittent abdominal pain; 4 cases showed fatty infiltration or atrophy of pancreas and 3 cases showed no obvious abnormality by pancreatic magnetic resonance imaging or B-ultrasound. All 8 children were given pancreatic enzyme replacement therapy, follow-up visit of 2.3 (1.2,3.2) years. Diarrhea significantly improved in 6 cases, and 1 case was added omeprazole due to poor efficacy. A total of 20 variations of CFTR were detected in this study, of which 7 were novel (c.1373G>A,c.1810A>C,c.270delA,c.2475_2478dupCGAA,c.2489_c.2490insA, c.884delT and exon 1 deletion). Conclusions: There is a high proportion of exocrine pancreatic insufficiency in Chinese patients with cystic fibrosis. The main clinical manifestations are steatorrhea and malnutrition. Steatorrhea has often started from infancy. Pancreatic enzyme replacement therapy can significantly improve the symptoms of diarrhea and malnutrition.

Lupus enteritis is a rare, severe complication of systemic lupus erythematosus (SLE), needing prompt diagnosis and proper management. However, SLE rarely presents as lupus enteritis at the time of initial diagnosis. Thus, delayed diagnosis and misdiagnosis are common. We report a case of a 25-year-old woman with lupus panenteritis. The patient had multiple hospitalizations for abdominal pain, nausea, and diarrhea, initially without any other symptoms suggestive of SLE, but was later observed to have malar rash and oral ulcers. Laboratory investigations were compatible with SLE, including positive antinuclear antibody (1:320) with speckled pattern. CT revealed diffuse hypodense submucosal thickening of the stomach, the entire small bowel, colon, appendix, and rectum. Treatment with high-dose corticosteroids followed by maintenance therapy with mycophenolate mofetil, hydroxychloroquine, and azathioprine resulted in clinical improvement. Diagnosis of lupus enteritis requires a high index of suspicion given the low incidence and nonspecific clinical findings.

BACKGROUND/AIMS: Advanced age is a known risk factor of poor outcomes for colitis, including Clostridium difficile infection (CDI). The present study compares the clinical outcomes of young and old patients hospitalized for CDI. METHODS: The clinical records of patients admitted from January 2007 to December 2013 with a diagnosis of CDI were analyzed. Patient baseline characteristics, clinical courses, and outcomes were compared with respect to age using a cut-off 65 years. RESULTS: Of the 241,391 inpatients registered during the study period, 225 (0.1%) with a diagnosis of CDI were included in the study. The mean patient age was 67.7 years. Seventy-two patients (32.0%) were younger than 65 years and 153 patients (68.0%) were 65 years old or more. The male to female ratio in the younger group was 0.8, and 0.58 in the older group. All 225 study subjects had watery diarrhea; six patients (8.3%) complained of bloody diarrhea in the young group and 21 patients (13.7%) in the old group (p=0.246). Right colon involvement was more common in the old group (23.5% vs. 42.7%, p=0.033). Furthermore, leukocytosis (41.7% vs. 67.3%, p=0.000), a CDI score of > or =3 points (77.8% vs. 89.5%, p=0.018), and hypoalbuminemia (58.3% vs. 76.5%, p=0.005) were more common in the old group. Failure to first line treatment was more common in the old group (17 [23.6%] vs. 58 [37.9%], p=0.034). CONCLUSIONS: Severe colitis and failure to first line treatment were significantly more common in patients age 65 years or more. More aggressive initial treatment should be considered for older CDI patients.

OBJECTIVETo study the effect of β-lactamase (BLs) detection and β-lactam/β-lactamase inhibitor (BL/BLI) on the incidence of antibiotic-associated diarrhea (AAD) in children with severe bacterial pneumonia.

METHODSThe clinical data of the children with bacterial severe pneumonia were retrospectively studied. Of all the patients, 248 using amoxicillin/clavulanate but without BLs detection and 323 using amoxicillin (BLs negative) or amoxicillin/clavulanate (BLs positive) were used as the amoxicillin group; 208 patients using piperacillin/tazobactam but without BLs detection and 291 patients using piperacillin (BLs negative) or piperacillin/tazobactam (BLs positive) were used as the piperacillin group; and 191 patients using cefoperazone/sulbactam but without BLs detection and 341 patients using cefoperazone (BLs negative) or cefoperazone/sulbactam (BLs positive) were used as the cefoperazone group. The incidence and clinical symptoms of AAD between the undetected and detected BLs patients were compared.

RESULTSThe incidences of AAD in the amoxicillin, piperacillin and cefoperazone groups without BLs detection groups were significantly higher than those in the corresponding groups with negative or positive results of BLs detection (P<0.01). The durations of diarrhea, antibiotic use and hospitalization stay in AAD patients receiving BLs detection were shorter than in those without receiving BLs detection (P<0.01).

CONCLUSIONSIt is very important to detect BLs for reducing the incidence and relieving symptoms of AAD in children with severe bacterial pneumonia.

Norovirus (NoV) is a pathogen that commonly causes viral diarrhea in children. Studies indicate that NoV recognizes human histo-blood group antigens (HBGAs) as cell attachment factors. In order to explore the correlation between of NoV infection and HBGAs, a cross-sectional study was conducted in children less than five years old who were hospitalized with diarrhea in two areas of China between November 2014 and February 2015. Of the paired stool and saliva samples taken from 424 children, NoV was detected in 24 (6%) children, with viral genotypes GII.3 (n=5), GII.4 (n=14), GII.12 (n=1), and GII.17 (n=4). All of the individuals having NoV infection were either secretors (Lea-b+/Lex-y+) or partial secretors (Lea+b+/Lex+y+) except one GII.3 infection of a non-secretor (Lea+b-/Lex+y-). These results suggest that secretor positive is associated with NoV infection, although non-secretors are not absolutely protected from NoV infection.

OBJECTIVETo investigate the development of lactose intolerance in neonates with non-infectious diarrhea and its association with diarrhea, and to evaluate the diagnostic values of fecal pH value and urine galactose determination for neonatal lactase deficiency.

METHODSSeventy hospitalized neonates who developed non-infectious diarrhea between October 2012 and June 2015 were enrolled as the diarrhea group, and 162 hospitalized neonates without non-infectious diarrhea were enrolled as the non-diarrhea group. Test paper was used to determine fecal pH value. The galactose oxidase method was used to detect urine galactose. The neonates with positive galactose oxidase were diagnosed with lactase deficiency, and those with lactase deficiency and diarrhea were diagnosed with lactose intolerance. According to the results of urine galactose detection, 69 neonates in the diarrhea group who underwent urine galactose detection were classified into lactose intolerance group (45 neonates) and lactose tolerance group (24 neonates), and their conditions after treatment were compared between the two groups. The follow-up visits were performed for neonates with diarrhea at 3 months after discharge.

RESULTSFecal pH value and positive rate of urine galactose (65% vs 54%) showed no significant differences between the diarrhea and non-diarrhea groups (P>0.05). Fecal pH value showed no significant difference between the lactose intolerance and lactose tolerance groups (P>0.05), while the neonates in the lactose intolerance group had a significantly longer time to recovery of defecation than those in the lactose tolerance group (P<0.05).

CONCLUSIONSThe incidence of lactase deficiency is high in neonates, and diarrhea due to lactose intolerance tends to occur. Determination of fecal pH value has no significance in the diagnosis of lactose intolerance in neonates with diarrhea.
