Abdominal cramping and diarrhea

On the basis of the patient's history and presentation, the likely diagnosis is extensive UC. Extensive colitis is defined by the presence of disease activity proximal to the splenic flexure. Because disease activity in UC is dynamic, up to half of patients who present with proctitis and 70% of those who present with left-sided colitis go on to develop extensive colitis on follow-up. 

On the basis of the workup, it appears that this patient's UC has transitioned from left-sided to extensive disease, given the loss of treatment response. Endoscopic evaluation of patients with loss of treatment response may reveal patchiness of the histologic activity, as seen in this case. 

Extensive colitis is a poor prognostic factor in UC, as is systemic steroid requirement, young age at diagnosis, and an elevated C-reactive protein level or erythrocyte sedimentation rate, all of which are associated with higher rates of colectomy. Over time, patients living with extensive ulcerative colitis develop an increased risk for colorectal cancer. Routine colonoscopic screening and surveillance are recommended for these high-risk patients.

UC most often presents as a continuously inflamed segment involving the distal rectum and extending proximally. Endoscopic features of inflammation include loss of vascular markings; granularity and friability of the mucosa; erosions; and, in the setting of severe inflammation, ulcerations and spontaneous bleeding. The diagnosis of UC involves both a lower gastrointestinal endoscopic examination and histologic confirmation. In general, a complete colonoscopy including examination of the terminal ileum should be performed, allowing clinicians to assess the full extent of the disease while ruling out distal ileal involvement, which is characteristic of Crohn's disease.

Evaluation of UC during relapses should include assessment of symptom severity and potential triggers, including enteric infections, use of nonsteroidal anti-inflammatory drugs, and recent smoking cessation. Nonadherence to therapy is common in patients with UC and may lead to relapse. 

To treat a patient like the one represented here, the American College of Gastroenterology guidelines recommend oral 5-ASA at a dose of at least 2 g/d to induce remission. However, because this patient lost response to this treatment, the next step in the guidelines are appropriate oral systemic corticosteroids.
