Abstract

Ulcerative colitis (UC) is a long-term inflammatory condition that causes the intestinal mucosa to become inflamed over and over again. To treat it, you need a planned and goal-oriented approach. The major goal of therapy is to achieve long-term steroid-free remission while lowering the adverse effects and problems that come with treatment and the condition. Topical and oral 5-aminosalicylic acid (5-ASA) formulations are used for mild cases, whereas systemic corticosteroids, immunomodulators, and biologic therapies are utilized for moderate to severe cases. Consequently, these treatment strategies are dictated by the severity, scope, and clinical trajectory of the disease. Patients with refractory illness may need advanced therapies, such as calcineurin inhibitors (like cyclosporine or tacrolimus) or biologic medications (like infliximab), which are antibodies that fight tumor necrosis factor-alpha. Surgery is still needed for problems like toxic megacolon, perforation, or severe refractory hemorrhage. To get the best outcomes from this kind of treatment, intestinal inflammation has to be precisely measured. Faecal calprotectin has emerged as a reliable, non-invasive biomarker for intestinal inflammation in recent years. It is very useful in medicine for keeping track of illnesses, predicting relapses, and evaluating how well treatments are working. Integrating it into clinical practice allows for quick changes to treatment and better disease activity evaluation. Including fecal calprotectin in clinical decision-making makes it feasible to have a more personalized and proactive treatment plan. This makes it possible to use faecal calprotectin-guided approaches that cut down on the necessity for invasive procedures like colonoscopy. Because of this, faecal calprotectin is very important for better managing UC, improving the results of the disease, and making treatment decisions that follow approved global standards.
