RESUMO
Objective: This study aimed to assess the effects of multi-donor fecal microbiota transplantation (FMT) capsules combined with thalidomide on hormone-dependent ulcerative colitis (UC). Methods: A total of 59 patients with steroid-dependent UC treated at the Gastroenterology Department of the First Affiliated Hospital of Xinxiang Medical University between January 2017 and January 2019 were enrolled in this study. Using a random number table, the patients were divided into two groups: a group treated with FMT capsules (the FMT group) and a group treated with FMT capsules and thalidomide (the FMT+S group). Multi-donor FMT capsules were prepared, and all subjects and stool donors followed the FMT pathway for FMT transplantation. Each patient's Mayo score, C-reactive protein (CRP) level, and level of fecal calprotectin before FMT treatment and at week 1 and week 13 after treatment were recorded. All patients were followed up for 15 weeks. Results: A total of 56.7% of the patients (34/59) achieved a therapeutic response at the end of the research period. Compared with the FMT group, the FMT+S group had better clinical benefit (P < 0.05). In the comparison of efficacy at week 1 and week 13 after treatment, the Mayo scores, calprotectin levels, and CRP indexes in the FMT+S group were better than those in the FMT group (P < 0.05). There were no serious adverse events in the treatment process or during follow-up. Conclusion: A combination of FMT capsules and thalidomide provides a treatment choice for patients with hormone-dependent UC, and it can be used as an adjuvant therapy. However, large-scale, multi-center, and prospective trials are required to further verify the reliability of this treatment.
RESUMO
PURPOSE: Oxidative stress was significantly associated with the development of malignancies. The purpose of this study was to evaluate the significance of serum total oxidant/antioxidant status in operable advanced gastric cancer patients. MATERIALS AND METHODS: A total of 284 patients who underwent curative resection for primary stage III gastric cancer were enrolled. Total oxidant status, total antioxidant status, and oxidative stress index (OSI) were evaluated within 24 hours before surgery, and compared with 120 healthy donors. The correlation between the OSI and survival outcome was analyzed by the Kaplan-Meier method with log-rank test and Cox's regression methods, respectively. RESULTS: Mean OSI of gastric cancer patients was higher than healthy controls (1.41±0.96 vs 0.78±0.42, P<0.001). All patients were stratified into two groups using the optimal cutoff value (1.42) of OSI using a sensitivity of 94.1% and a specificity of 64.0% as optimal conditions from receiver operating curve analysis. Patients with an OSI ≥1.42 had poorer mean overall survival (45.6 vs 29.8 months, P=0.022) and mean recurrence-free survival (43.3 vs 28.1 months, P=0.011) than patients with an OSI <1.42 in univariate analysis, and OSI was also confirmed as an independent predictor for survival for gastric cancer in multivariate analysis (hazard ratio, 0.541; 95% CI: 0.127-1.102; P=0.01). CONCLUSION: Preoperative OSI can be considered as an independent prognostic factor for operable and advanced gastric cancer.
RESUMO
Background: Severe acute pancreatitis (SAP) is characterized by the noxious combination of severe systemic inflammation and hypoperfusion and oxidative stress. Ischemia-modified albumin (IMA) was recognized as a novel marker of oxidative stress and ischemia. The purpose of this study was to evaluate serum IMA level in patients with SAP and analyze its prognostic significance. Methods: A total of 72 patients with SAP were enrolled. Serum IMA level was measured within 24 hours of the onset of SAP, and baseline characteristics were recorded. The BISAP, APACHE II and SOFA scores were calculated. Multivariate logistic regression and receiver operating characteristic curve analyses were used to evaluate predictive ability of LMA for in-hospital mortality of SAP. Kaplan-Meier analysis was further used to compare in-hospital mortality difference between high LMA and low LMA. Results: The overall in-hospital mortality rate of all 72 SAP patients was 23.6%. Non-survivor group had higher serum IMA (107.2±10.8 VS 88.4±11.9, P<0.05) than survivor group. Otherwise, the optimal cutoff levels for the IMA predicting in-hospital mortality of patients with SAP was 112 U/ml using a sensitivity of 77.4% and a specificity of 76.2% as optimal conditions (AUC, 0.734; 95% CI: 0.615-0.852; P=0.002). IMA level also was confirmed as an independent prognostic factor for SAP in multivariate analysis. Patient with high IMA level (≥112 U/ml) had poorer survival rate than low IMA (<112 U/ml) in log-rank test of Kaplan-Meier survival analysis (P<0.05). Conclusions: Serum IMA level can be considered as an independent predictor for in-hospital mortality of patients with SAP.
