RESUMO
BACKGROUND AND AIM: Although the fluoropyrimidines are effective chemotherapeutic agents for malignant gastrointestinal tumors, they sometimes cause enteritis with diarrhea. Severe treatment-related diarrhea may result in chemotherapy discontinuation. We investigated the relationship between diarrhea severity and fluoropyrimidine-induced small intestinal mucosal injury. METHODS: We performed small bowel capsule endoscopy in patients undergoing chemotherapy including fluoropyrimidine for a malignant tumor between May 2017 and June 2018 and analyzed the relationship between the endoscopic findings and diarrhea severity. We also performed a cross-sectional analysis of patient factors and routes of chemotherapy to identify risk factors of fluoropyrimidine-induced small intestinal injury. RESULTS: Small bowel capsule endoscopy was successfully completed in 16 eligible patients. The diarrhea grade (per the Common Terminology Criteria for Adverse Events, version 4.0) was significantly correlated with the percentage of patients with a small intestinal mucosal break (grade 0, 16.7%; grade 1, 57.1%; grade 2, 100%; p = .016, Cochran-Armitage trend test). Compared to patients receiving intravenous therapy, those receiving an orally administered fluoropyrimidine had a significantly greater number of small intestinal mucosal breaks (median number of breaks [range]; intravenous 5-fluorouracil, 0 [0-13]; oral fluoropyrimidine, 6.5 [1-20]; p = .0162, Mann-Whitney U test). CONCLUSIONS: Many patients with diarrhea caused by chemotherapy including fluoropyrimidine had small intestinal mucosal breaks. Additionally, small intestinal mucosal breaks were more severe in patients receiving a regimen of oral treatment than in those receiving a regimen of intravenous therapy. These outcomes have important implications for investigations of new strategies for preventing anti-cancer drug-induced diarrhea.

BACKGROUND: We aimed to investigate how high-dose ecabet sodium affects low-dose aspirin-induced small intestinal mucosal injury in healthy volunteers. METHODS: Healthy volunteers were enrolled randomly into one of two groups with the following drug regimens for 2 weeks: group A, low-dose aspirin once per day and group B, low-dose aspirin and 4.0 g of ecabet sodium. Small bowel capsule endoscopy was performed before and 2 weeks after low-dose aspirin administration. RESULTS: A significant difference was found in the median number [range] of small intestinal lesions between baseline and two weeks after low-dose aspirin administration in group A (baseline: 1 [0-5], after: 5 [1-11]; p = 0.0059) but not in group B (baseline: 0.5 [0-9], after: 3 [0-23]; p = 0.0586). In group B, although the median number [range] of lesions in the first tertile of the small intestine did not increase two weeks after low-dose aspirin administration (baseline: 0 [0-4], after: 1.5 [0-8]; p = 0.2969), the number of lesions in the second and third tertiles of the small intestine increased significantly (baseline: 0 [0-5], after: 2 [0-15]; p = 0.0469). CONCLUSIONS: Ecabet sodium had a preventive effect on low-dose aspirin-induced small intestinal mucosal injury in the upper part of the small intestine.

Chemotherapy-induced diarrhea (CID) is a common, severe side effect of chemotherapy, immunotherapy, and targeted therapy. Because patients are more prone to continuing chemotherapy if they do not suffer from CID, appropriate diagnosis and monitoring of this disease are essential. However, suitable monitoring methods are yet to be developed. To date, several studies have shown that small-bowel capsule endoscopy (SBCE) is useful in visualizing the entire small intestinal mucosa and detecting small intestinal abnormalities, including bleeding, malignant tumors, and mucosal injury, associated with the use of nonsteroidal anti-inflammatory drugs and low-dose aspirin. Currently, limited studies have evaluated the small intestinal mucosa using SBCE in patients receiving fluoropyrimidine-based chemotherapy or immune checkpoint inhibitors. These studies have reported that small intestinal mucosal injury is common in patients with severe fluoropyrimidine-induced diarrhea. SBCE might be a useful screening method for the early detection of enterocolitis induced by immune checkpoint inhibitors. SBCE may be a powerful tool for the diagnosis and monitoring of CID, and understanding its indication, contraindication, and capsule-retention risk for each patient is important for clinicians.
RESUMO
OBJECTIVE: To investigate the effects of Weikang Capsule (, WKC) on aspirin-related gastric and small intestinal mucosal injury by magnetically controlled capsule endoscopy (MCCE). METHODS: Patients taking enteric-coated aspirin aged 40-75 years were enrolled in Beijing Anzhen Hospital, Capital Medical University from January 2019 to December 2019. The patients continued taking aspirin Tablet (100 mg per day) and underwent MCCE before and after 1-month combined treatment with WKC (0.9 g per time orally, 3 times per day). The gastrointestinal symptom score, gastric Lanza score, the duodenal, jejunal and ileal mucosal injury scores were used to evaluate the gastrointestinal injury before and after treatment. Adverse events including nausea, vomiting, abdominal pain, abdominal distension, abdominal discomfort, dizziness, or headache during MCCE and combined treatment were observed and recorded. RESULTS: Twenty-two patients (male/female, 13/9) taking enteric-coated aspirin aged 59.5 ± 11.3 years with a duration of aspirin use of 28.0 (1.0, 48.0) months were recruited. Compared with pre-treatment, the gastrointestinal symptom rating scale scores, gastric Lanza scores, and duodenal mucosal injury scores were significantly reduced after 1-month WKC treatment (P<0.05), and jejunal and ileal mucosal injury scores showed no obvious change. No adverse events occurred during the trial. CONCLUSIONS: WKC can alleviate gastrointestinal symptoms, as well as gastric and duodenal mucosal injuries, in patients taking enteric-coated aspirin; it does not aggravate jejunal or ileal mucosal injury, which may be an effective alternative for these patients (Clinical trial registry No. ChiCTR1900025451).
