Abstract

Background: Ulcerative colitis (UC) is a chronic inflammatory bowel disease that mostly affects the colon and rectum. The condition frequently causes symptoms such as diarrhea, abdominal pain and rectal bleeding. Additionally, the delayed diagnosis is common because UC symptoms often mimic those of other conditions, such as hemorrhoids and IBS. This report underscores the need for timely diagnosis and intervention, based on clinical, endoscopic, and biomarker testing, including the use of fecal calprotectin.

Case Presentation: A 24-year-old female presented to her primary care provider with complaints of bowel habit complaints, lower abdominal pain and rectal bleeding. She was initially misdiagnosed as having hemorrhoids and IBS with no systemic conditions suspected. Lab testing showed normal C-reactive protein (CRP <5 mg/L) and normal results on complete blood count (WBC 4.2 × 109/L, hemoglobin 13.2 g/dL, platelets 250 × 109/L, RBC 4.8 × 1012/L). Fecal calprotectin levels were notably high at 1035 μg/g; normal < 50 μg/g). A colonoscopy revealed a diagnosis of distal proctitis that was classified as Mayo score 3. The first-line treatment included the use of mesalamine both orally and as a topical agent. Clinical improvement and reduced fecal calprotectin (34 μg/g) were reported during follow-up, reflecting gastrointestinal mucosal healing and a positive response to therapy.

Conclusion: The usefulness of fecal calprotectin as a key biomarker in the evaluation of disease progression in UC is highlighted by this case. Appropriate diagnosis along with early mesalamine treatment contributed to symptoms relief and mucosal recovery. Immediate care is important in reducing complications and promoting patient recovery.
