Understanding the Impact of Perceived Stigma on Healthcare Perception and Medication Utilization Among Black Individuals with Inflammatory Bowel Diseases.

Confirm ulcerative colitis with endoscopy showing continuous colonic inflammation from the rectum plus histology, after excluding infection with two-step CDI testing. Treat mild-moderate disease with 5-ASA by route and extent (suppository for proctitis, enema for left-sided, oral plus rectal for extensive); if 5-ASA fails, treat as moderate-to-severe rather than stepping up gradually. Position advanced therapy by EFFICACY TIER, not by an anti-TNF-first rule. Advanced-therapy-naive, higher efficacy: infliximab, vedolizumab, ozanimod, etrasimod, upadacitinib, risankizumab, guselkumab; intermediate: golimumab, ustekinumab, tofacitinib, filgotinib, mirikizumab; lower: adalimumab. PREVIOUSLY TNF-EXPOSED, higher efficacy: tofacitinib, upadacitinib, ustekinumab; lower: adalimumab, vedolizumab, ozanimod, etrasimod - S1P modulators are weakest in exactly this group. Do not cycle within the anti-TNF class after primary non-response; switch mechanism. Apply treat-to-target (STRIDE-II) to endoscopic improvement (MES 0-1). Screen for acute severe UC by Truelove-Witts and admit for IV steroids. Begin CRC surveillance 8-10 years after DIAGNOSIS for extensive or left-sided disease; isolated proctitis follows average-risk screening.
