ABSTRACT
Research advances in the oncology treatment field have led to the widespread use of immunotherapy. The usage of immune checkpoint inhibitor (ICI) has improved the survival of cancer patients with metastases. This has also led to the rapidly expanding indications for ICI use. However, ICI usage may lead to toxicity, which may be immune-related, in different organ-specific targets. The immune-related adverse events (irAEs) of ICI may lead to increased morbidity, decreased quality of life, and early termination of ICI. The clinical manifestations of irAEs in the gastrointestinal system are variable, ranging from self-limited to life-threatening or fatal events. In this review article, we would like to focus on discussing ICI-induced colitis, which is one of the most common ICI irAEs in the gastrointestinal tract.
ABSTRACT
Anemia is the most common extraintestinal inflammatory bowel disease (IBD) manifestations and is significantly correlated with several adverse impacts such as higher hospitalization rate, relapse rate, surgical intervention requirement, and low quality of life. The prevalence of anemia in IBD patients is greatly varied between reports, which is estimated between 8.8% to 74%. However, studies showed there were still gaps in the screening protocol and anemia treatment in daily practice. Anemia in IBD tends to be an overlooked IBD complication yet significant and must be adequately addressed. Anemia in IBD may be caused by several factors that interplayed, with iron deficiency anemia being the most common etiology. Comprehensive management of anemia in IBD should consist of active screening, evaluation of the etiology, holistic treatment, and follow-up monitoring. Optimization of IBD therapy should be emphasized because it also may improve the anemic condition. A multidisciplinary approach and collaboration are needed to ensure better IBD care.
