RESUMEN

Background: Clostridium difficile infection (CDI) is the most common cause of hospital-acquired diarrhea and an important cause of death in hospitalized patients with diarrhea. However, there are not sufficient clinical researches on the risk factors of CDI. Aims: To investigate the risk factors of CDI in hospitalized patients with diarrhea. Methods: A total of 230 hospitalized diarrhea patients who received Clostridium difficile test from January 2015 to January 2019 at the Second Hospital of Hebei Medical University were collected. The patients were divided into CDI group and non-CDI group. Logistic regression analysis was performed to investigate the risk factors of CDI. Results: Compared with non-CDI group, patients in CDI group had a longer hospital stay (P<0.05) and a higher proportion of surgery in the past 6 months (P<0.05). The number of comorbidities in CDI group was higher than that in non-CDI group (P<0.05), and the ratio of gastrointestinal disease, cardiovascular disease, blood/immune system disease, nervous system disease in CDI group were higher than those in non-CDI group (P<0.05). Multivariate analysis showed the number of comorbidities (OR=3.215, 95% CI: 1.576-4.743; P=0.003), gastrointestinal disease (OR=4.135, 95% CI: 3.048-11.416; P=0.000), surgical history (OR=6.734, 95% CI: 2.692-15.849; P=0.000) and antibiotic use (OR=5.996, 95% CI: 2.173-15.481; P=0.000) were risk factors of CDI, especially the use of quinolone antibiotics (OR=4.769, 95% CI: 2.138-14.757; P=0.000). Conclusions: CDI can prolong the hospital stay of patients with diarrhea. Number of comorbidities, underlying gastrointestinal disease, recent history of surgery and antibiotic use, especially the use of quinolone antibiotics are risk factors of CDI in hospitalized patients with diarrhea.

RESUMEN

Objective:To explore the risk factors, clinical features, endoscopic characteristics and the efficacy of antiviral therapy in ulcerative colitis (UC) patients complicated with cytomegaloviremia (CMV) and Epstein-Barr (EB) viremia.Methods:From April 1, 2014 to January 31, 2019, at The Second Hospital of Hebei Medical University, a total of 320 UC patients hospitalized at the Department of Gastroenterology were enrolled. According to the pathogens, the patients were divided into four groups: complicated with CMV and EB viremia group ( n=35), only complicated with CMV viremia group ( n=33), only complicated with EB viremia group ( n=52) and without CMV and EB viremia group ( n=200). Clinical features and the efficacy of antiviral therapy of the patients were retrospectively analyzed. Multivariate logistic regression was used to analyze the risk factors of UC complicated with CMV and EB viremia. Kruskal-Wallis H test, Chi-square test and Fisher exact test were used for statistical analysis. Results:The proportion of patients of age>60 years old (42.86%, 15/35), the rate of glucocorticoid use (51.43%, 18/35) within three months before onset and the inefficacy rate of glucocorticoid treatment (22.86%, 8/35) of UC complicated with CMV and EB viremia group were all higher than those of UC without CMV and EB viremia group (14.00%, 28/200; 24.50%, 49/200; 1.00%, 2/200), and the differences were statistically significant ( χ2=17.062, 10.598 and 29.769; all P<0.01). However, there were no statistically significant differences between UC complicated with CMV and EB viremia group and UC without CMV and EB viremia group in gender, and treatment of 5-aminosalicylic acid (5-ASA), azathioprine and infliximab within three months before onset (all P>0.05). The proportion of patients with fever (54.29%, 19/35), abdominal pain (91.43%, 32/35), hematochezia (94.29%, 33/35), weight loss (28.57%, 10/35), severe disease activity (94.29%, 33/35), total colon involvement (91.43%, 32/35), serum albumin less than 30 g/L (71.43%, 25/35) and hemoglobin less than 100 g/L (48.57%, 17/35) of UC complicated with CMV and EB viremia group were all higher than those of UC without CMV and EB viremia group (13.50%, 27/200; 43.00%, 86/200; 44.00%, 88/200; 13.50%, 27/200; 38.00%, 76/200; 65.00%, 130/200; 18.00%, 36/200 and 18.50%, 37/200), and the differences were statistically significant ( χ2=31.475, 27.945, 32.930, 5.100 and 40.194, Fisher exact test, χ2=44.242 and 15.220, all P<0.01). However, there were no statistically significantl differences in clinical classification and disease course (all P>0.05). The incidence rates of deep ulcer (45.71%, 16/35), irregular ulcer (42.86%, 15/35) and longitudinal ulcer (8.53%, 3/35) under endoscopy of UC complicated with CMV and EB viremia group were significantly higher than those of UC without CMV and EB viremia group (1.50%, 3/200; 3.50%, 7/200 and 1.00%, 2/200), and the differences were statistically significant ( χ2=72.521 and 49.837, Fisher exact test, all P<0.01). The incidence rates of deep ulcer and irregular ulcer under endoscopy of UC complicated with CMV and EB viremia group were higher than those of UC only complicated with EB viremia group (15.38%, 8/52 and 11.54%, 6/52), and the differences were statistically significant ( χ2=9.663 and 11.206, P=0.002 and 0.001). The results of Multivariate Logistic regression analysis showed that severe disease activity, serum albumin level less than 30 g/L, and deep ulcer and irregular ulcer under endoscopy were risk factors of UC patients complicated with CMV and EB viremia (odds ratio=48.519, 44.352, 53.432 and 39.989, 95% confidence interval 9.057 to 587.669, 4.499 to 437.245, 3.302 to 864.670 and 3.418 to 467.910, all P<0.05). The improvement rate of antiviral therapy in UC complicated with CMV and EB viremia group (73.53%, 25/34) was significantly lower than those of UC only complicated with CMV group (96.88%, 31/32) and UC only complicated EB viremia group (95.65%, 44/46), and the differences were statistically significant ( χ2=6.989 and 6.310, P=0.008 and 0.012). Conclusions:UC patients with severe disease activity, serum albumin level less than 30 g/L, and deep ulcer and irregular ulcer under endoscopy are more likely to develop CMV and EB viremia. The more severe the disease, the worse the treatment response, so it is necessary to strengthen the screening to CMV and EB virus infection in UC patients.

RESUMEN

Inhibition of NEDD8 activating enzyme (NAE),the rate limiting enzyme in Neddylation,can suppress the activity of ubiquitin-proteasome system (UPS) pathway and decrease degradations of related proteins,resulting in cell apoptosis.Compared with the proteasome inhibitors,NAE inhibitors can interfere with cellular homeostasis with more specificity.With the rapid development of the research on NAE,a variety of NAE inhibitors have been reported.According to the structure characteristics,NAE inhibitors can be divided into the AMP analogues,double flavonoids deoxidization duckbill alkali ketone derivatives and metal rhodium complex classes,etc.The process of ubiquitinated modified Neddylation,NAE and physiological role of tumor has been introduced in this paper,and the latest progress of NAE inhibitors also has been summarized.
