HLA-DRB1*01:03 and severe ulcerative colitis

About The Study: Among individuals with ulcerative colitis, the allele HLA-DRB1*01:03 was associated with severe ulcerative colitis requiring major operation, hospitalization, and systemic corticosteroid use compared with less severe disease. HLA-DRB1*01:03 has previously been linked to ulcerative colitis incidence. This study supports earlier, targeted genetic studies comparing patients with healthy controls reporting an association with total disease and severe disease requiring colectomy.
