Summary

This study looks at how weight and body mass index (BMI) change in people with inflammatory bowel disease (IBD) who are treated with biologic drugs. Researchers will track weight monthly and see if higher BMI leads to higher drug doses and costs. The goal is to understand the financial impact of these treatments based on body size.

Who is studied

* Patients underwent clinical, laboratory, endoscopic, and/or imaging evaluations as part of routine outpatient monitoring. Current medications and Serum IFX concentrations will offered for collection. * Laboratory investigations (Complete blood picture, Liver function tests, C-reactive protein and ESR, Fecal calprotectin). * The following variables were evaluated: age, sex, BMI \[weight (kg)/height (m)²\], smoking history, history of IBD-related surgeries, current and prior concomitant medications, disease duration, Montreal classification, and clinical activity indices for CD and UC. Clinical activity of CD was assessed using the Harvey-Bradshaw Index (HBI), with clinical remission defined as an HBI score ≤ 4 points. * Clinical activity of UC was assessed using the partial Mayo score, with clinical remission defined as a score ≤ 2 points
