Introduction: Clostridioides difficile infection (CDI) is a major complication in patients with inflammatory bowel disease (IBD), contributing to increased morbidity, mortality, and health care burden. This study aimed to evaluate national trends and clinical outcomes associated with CDI in hospitalized IBD patients in the United States. Methods: We conducted a retrospective cohort study using the National Inpatient Sample (NIS) from 2012 to 2021. Adult patients hospitalized with a primary or secondary diagnosis of IBD (Crohn’s disease or ulcerative colitis) were stratified into 2 groups by the status of CDI diagnosis (either primary or secondary diagnosis). Demographic characteristics, hospital outcomes, and complications were compared between CDI and non-CDI cohorts. Multivariable logistic regression was used to identify independent predictors of in-hospital mortality, septic shock, and venous thromboembolism (VTE). Results: Among 4,193,564 hospitalized IBD patients, 534,190 (12.7%) had CDI. CDI patients were older (mean: 68.8 vs 53.3 y, P < 0.001), with higher in-hospital mortality (3.6% vs 2.0%, P < 0.001), VTE (23.7% vs 6.2%, P < 0.001), septic shock (5.4% vs 4.0%, P < 0.001), and mechanical ventilation use (4.2% vs 2.8%, P < 0.001). Ulcerative colitis was more frequently associated with CDI than Crohn’s disease (30.3% vs 25.0%, P < 0.001) and independently predicted septic shock (OR: 1.09) and VTE (OR: 1.06) but was associated with lower mortality (OR: 0.81). Conclusion: The presence of CDI in hospitalized patients with IBD led to significantly worse outcomes. Ulcerative colitis is more commonly associated with CDI and increased risk of complications. These findings highlight the need for early detection, preventive strategies, and tailored management of CDI in the IBD population.

Background: Cerebral venous sinus thrombosis (CVT) is a rare cause of stroke, constituting 0.5–3% of all strokes with an extremely varied spectrum of presentation, predisposing factors, neuroimaging findings, and eventual outcomes. A high index of suspicion is needed because timely diagnosis can significantly alter the natural course of the disease, reduce acute complications, and improve long-term outcomes. Due to its myriad causative factors, protean presentation, and association with several systemic diseases, CVT is encountered not only by neurologists but also by emergency care practitioners, internists, hematologists, obstetricians, and pediatricians. Discussion: Anticoagulation remains the mainstay of treatment for CVT. Heparin and warfarin previously had been the anticoagulation of choice. Recently there has been an increased interest in utilizing direct-acting oral anticoagulants in the treatment of CVT given comparable safety and efficacy with ease of utilization. However recent clinical guidelines given by multiple societies including the American Stroke guidelines and European guidelines do not include these agents so far in their treatment recommendations. Ongoing multicentric clinical trials are currently reviewing the role of these agents in both short-term as well as long-term. Our review of the literature supports the safety and reinforces the efficacy of DOAC in the treatment of CVT. Additionally, patient satisfaction has been shown to be better with the use of DOAC. In conclusion, DOAC continues to have a valid role in the management of CVT.
