Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Inflammatory bowel disease (IBD), including Crohn's disease (CD) and ulcerative colitis (UC), is a chronic inflammatory relapsing disorder affecting the gastrointestinal tract and is characterized by a progressive and unpredictable disease course.. The major subtypes are :

1. Crohn's Disease which affects any part of GIT.
2. Ulcerative Colitis which affects mainly the colon . And a subtype of IBD is called intermediate colitis (IC) when its unable to diffrentiate between UC and Crohns disease . There has been a global rise in the incidence of IBD over the last few decades, in 2017; there were 6.8 million cases of IBD globally. The age-standardized prevalence rate increased from 79.5 per 100, 000 population in 1990 to 84.3 per 100, 000 population in 2017. The annual incidence of Crohn's disease is 5.0 per 100,000 person-years in Asia and the Middle East, whereas incidence rates of ulcerative colitis are 6.3 per 100,000 person-years in Asia and the Middle East . some studies suggest the relative incidence ratio of UC and CD is 6:1 .Regarding UC the highest incidence of the disease is in Northern Europe and Canada at 24.3 and 19.2/100,000, respectively. Prevalence rates are also the highest in these two regions, at 505/100,000 in Northern Europe and 248/100,000 in Canada with incidence rate of 2.33 per 100,000 persons per year for UC in the Arab world Ulcerative colitis (UC) is a chronic, idiopathic inflammatory condition that affects the mucosa of the colon and rectum. Ulcerative colitis is also considered a progressive disease as it is associated with increased risk of disease extension, dysplasia/neoplasia, fibrosis and rectal dysfunction. Observational studies suggest that one-third of patients with left-sided colitis or disease limited to the rectum will develop pancolitis over a period of 10 years .

The changing epidemiology and the progressive nature of the disease require a clear understanding of the available and soon to become available therapeutic agents to treat UC and the different aspects of their pharmacology .

Treatments for inducing remission include 5-aminosalicylic acid drugs and corticosteroids. Maintenance treatments include 5-aminosalicylic acid drugs, thiopurines, biologics (eg,anti TNF , anti-cytokines and anti-integrins), and small molecules (Janus kinase inhibitors and sphingosine-1-phosphate receptor modulators) .

Infliximab is a biological therapy/immunotherapy medication designed to stimulate the body's immune system and treat certain diseases. Infliximab is a purified, recombinant DNA-derived chimeric IgG monoclonal antibody protein that contains both murine and human components that inhibit tumor necrosis factor-alpha (TNF-α). TNF-α is a signaling protein involved in acute phase reactions and systemic inflammation. Macrophages, CD4+ lymphocytes, NK cells, neutrophils, mast cells, eosinophils, and neurons produce TNF-α. This TNF-α inhibition inhibits the inflammatory reaction's cascade, leading to improved disease condition inflammatory bowel disease .

Infliximab has a high affinity for TNF-α and does not inhibit TNF-β. TNF-α is responsible for several physiological responses, including inducing proinflammatory cytokines (eg, IL-1 and IL-6), increasing adhesion molecule release, and enhancing the migration of leukocytes from blood vessels in the surrounding tissue (via increased endothelial permeability) . Infliximab is administered in dose 5 mg/kg i.v. for the whole induction and maintenance phase .

Ustekinumab is a human monoclonal IgG1 antibody that blocks the p40 subunit of both IL-12 and IL-23 this antagonistic action inhibits the interaction of these cytokines with the IL-12Rβ1 receptor. The IL-12Rβ1 receptor is found on the surface of NK cells and T cells which reduces inflammation and alters the body's immune response . ulcerative colitis treatment is based on an initial intravenous weight-based infusion followed by a subcutaneous maintenance schedule (90 mg subcutaneously eight weeks after initial intravenous administration and every eight weeks after that) .

The prognosis in UC is difficult to assess, however it should be emphasized that even one-third of patients need to undergo surgical treatment (colectomy) at different stages of the disease. Due to these data, together with the fact of increasing prevalence of UC reported in many industrialized and developing countries .

several treatment options now are available for the management of moderate-severe ulcerative colitis, with variable efficacy and safety profiles, and positioning different agents in the treatment course as first-line (in biologic-naïve patients) and second-line (in patients with prior exposure to tumor necrosis factor \[TNF\]-α antagonists) is a key knowledge gap. In the absence of head-to-head comparisons, prior network meta-analyses have attempted to address this gap, but have been limited by the number of studies especially at Egyptian population , that why this study will be conducted .
