Abstract

Objective To evaluate the application of proactive pro-drug therapy (TDM) at week six in users of infliximab therapy in ulcerative colitis patients and to analyze the need for further disease optimization.

Method This is a retrospective analysis that will be carried out simultaneously at the Hospital de Clínicas de Passo Fundo and at the Endoclin Diagnostic Center in the city of Passo Fundo, with secondary data collection between January 2020 and May 2022. The sample included patients from both sexes, regardless of age, who are being followed up in the services mentioned above, by signing the informed Free and Clarified Consent Term.

Results 63.2% of patients required optimization of their treatment based on the serum level assessment at week six.

Conclusion Proactive TDM performed at week six benefits patients in order to complete indications for treatment to avoid lack of drug response and complications from the disease.
