Brief summary: Detection of Inflammatory Bowel Disease activity by Using new measure : Neutrophil to lymphocyte ratio

Detailed description: Inflammatory bowel disease (IBD) has been a global healthcare problem with a sustained increasing incidence. It includes two major forms, Crohn's disease (CD) and ulcerative colitis (UC), which are distinct chronic bowel-relapsing inflammatory disorders (Gharagozloo et al., 2015). Ulcerative colitis (UC) is limitd to Mucosa and cause continuous bowel inflammation (Celikbilek et al., 2013) While Crohn disease is more complex because of its transmural inflammation and it is characterized by skip lesions, which are diseased sections of bowel next to uninvolved areas(Nishijima David L; Wisner, David H; Holmes, James F, 2016). The prevalence of IBD is highest in the second to third decade of life with another peak in the 60-70- year-old group.(Silva et al., 2016) Non-invasive tests, such as C reactive protein (CRP), erythrocyte sedimentation rate (ESR) and white blood cells (WBC) are therefore being increasingly recognized as important markers for initial diagnosis and disease activity detection.(Gao et al., 2015) In recent years, the neutrophil-to-lymphocyte ratio (NLR), calculated as total neutrophil count divided by total lymphocyte count, NLR represents two different immune pathways and can be easily derived directly from a standard blood test..(Argeny et al., 2018)
