Successful Treatment of Refractory Ulcerative Colitis With 5-Aminosalicylic Acid Intolerance and Biologic Therapy Resistance Using Combined Granulocyte and Monocyte Adsorptive Apheresis.

Abstract

We report the case of a 37-year-old male patient diagnosed with moderate left-sided ulcerative colitis (UC). Initial therapy with 5-aminosalicylic acid (5-ASA) was terminated within days due to exacerbation of symptoms, leading to a diagnosis of 5-ASA intolerance. Although induction of remission was achieved with prednisolone, the patient developed steroid dependency. Treatment with vedolizumab and ustekinumab subsequently failed to achieve clinical or endoscopic improvement. Intensive granulocyte and monocyte apheresis (GMA) was introduced, successfully inducing remission. However, during maintenance therapy with GMA, the patient experienced a relapse. Initiation of golimumab yielded suboptimal results, necessitating a combination therapy involving prednisolone and reintensified intensive GMA. This multimodal approach successfully achieved remission induction and maintenance. This case highlights the potential utility of intensive GMA in combination with golimumab and prednisolone for the management of refractory UC, particularly in patients with 5-ASA intolerance and failure of multiple biologic agents. A brief review of the relevant literature is included.
