Role of C-Reactive Protein /Albumin Ratio in evaluation of Disease Activity in Patients with Inflammatory Bowel Disease.

Inflammatory bowel disease (IBD) is defined as a life long chronic inflammatory disease affecting the gastrointestinal tract resulting from the interaction of environmental and genetic elements, has been a global healthcare problem with a steadily increasing incide IBD is mainly composed of two different bowel-relapsing disorders, including Crohn's disease (CD) and ulcerative colitis (UC).

Early detection of the disease activity of IBD is of great significance for the treatment of this disease, which can effectively prevent complications and therefore improve prognosis as well as quality of life. In current clinical practice, commonly used noninvasive biomarkers such as C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR), are considered to be important for both early diagnosis and accurate monitoring of the disease activity in IBD patients.

The C-reactive protein/albumin ratio (CAR) is indicative of the balance between inflammation and nutritional status, making it an excellent marker for assessing disease activity in patients The disease activity of UC and CD patients was evaluated by the Mayo score and Crohn disease activity inde (CDAI).
