  • Cytomegalovirus infection is associated with worse outcomes in inflammatory bowel disease hospitalizations nationwide. International journal of colorectal disease Hendler, S. A., Barber, G. E., Okafor, P. N., Chang, M. S., Limsui, D., Limketkai, B. N. 2020

    Abstract

    BACKGROUND: Cytomegalovirus (CMV) infection may complicate ulcerative colitis (UC) or Crohn's disease (CD) hospitalizations. Studies examining this relationship are often single-center examining short time periods.AIMS: To quantify the prevalence of CMV and its impact on outcomes among UC and CD hospitalizations over time using nationwide administrative databases.METHODS: The National Inpatient Sample and Nationwide Readmissions Database were analyzed to calculate CMV prevalence per 1000 UC and CD hospitalizations between 1998 and 2014. Univariable and multivariable logistic and linear regression were used to assess CMV's association with outcomes. Separate analyses examined effects from the introduction of anti-TNF therapy in UC in 2005, CD anatomic extent, and Clostridioides difficile infection.RESULTS: Among UC, from 1998 to 2014, the prevalence of CMV infection rose from 1.4 to 6.3 per 1000 UC hospitalizations (p<0.001), although this increase was not statistically significant for the years 2006 to 2014 (p=0.07). Among CD, prevalence rose from 0.3 to 1.8 per 1000 CD hospitalizations (p<0.001) from 1998 to 2014. CMV was independently associated with increased inpatient mortality (UC: odds ratio (OR) 2.3, 95% confidence interval (CI) 1.2-4.5; CD: OR 4.6, CI 1.5-13.7), colectomy in UC (OR 2.5, CI 1.9-3.3), and higher length of stay and costs.CONCLUSION: CMV infection's prevalence among UC and CD hospitalizations is rising over time, but may have slowed after 2005 in UC. CMV is independently associated with increased inpatient mortality, length of stay, and hospital charges in UC and CD and with colectomy in UC.

  • Rising Incidence of Intestinal Infections in Inflammatory Bowel Disease: A Nationwide Analysis. Inflammatory bowel diseases Barber, G. E., Hendler, S., Okafor, P., Limsui, D., Limketkai, B. N. 2018

    Abstract

    Intestinal infections are common in patients with inflammatory bowel disease (IBD) and may mimic IBD flares. In this study, we estimate the changing incidence of intestinal infections among IBD hospitalizations and assess the impact of intestinal infections on key hospitalization metrics.The National Inpatient Sample (NIS) was analyzed for hospitalizations from IBD between 1998 and 2014. Intestinal infections were identified using ICD-9-CM codes, and incidence for each infection was calculated for Crohn's disease (CD) and ulcerative colitis (UC). Linear and logistic regression analyses were used to assess the effects of intestinal infections on hospitalization duration, charges, and mortality.There were 4,030,620 hospitalizations for IBD between 1998 and 2014. The annual incidence of intestinal infections rose from 26.2 to 70.6 infections per 1000 IBD hospitalizations (Ptrend < 0.01). A main driver of this rising incidence was Clostridium difficile infections, which increased from 7.8 to 32.1 per 1000 CD hospitalizations and from 23.0 to 84.7 per 1000 UC hospitalizations (Ptrend < 0.01). The incidence of other intestinal infections increased from 10.2 to 15.3 per 1000 CD hospitalizations and 16.5 to 25.3 per 1000 UC hospitalizations. Intestinal infections and particularly C. difficile infections were associated with longer hospitalizations, greater hospital charges, and greater all-cause mortality.The incidence of intestinal infections among hospitalized IBD patients has increased over the past 15 years, primarily driven by C. difficile infections. Intestinal infections are associated with length of stay, hospital charges, and all-cause mortality. More aggressive measures for prevention of C. difficile infections are needed. 10.1093/ibd/izy086_video1izy086.video15779257979001.
