We herein report a case of Behçet's disease in a 27-year-old female who suffered from generalized skin rashes for one week. After hospitalization, massive bloody stools accompanying hypovolemic shock occurred. Emergency abdominal computed tomography-angiography failed to detect the bleeding source. Esophagogastroduodenoscopy also demonstrated no definite bleeding points. Ileocolonoscopy showed multiple large and deep ulcers with some blood coating and mild oozing in the terminal ileum. We initially performed epinephrine injection and hemoclips for her intestinal bleeding. However, massive bloody stools still continued. Thus, we prescribed a loading dose of 160 mg adalimumab followed by weekly 80 mg adalimumab subcutaneous injections to the patient. Following this treatment, her gastrointestinal bleeding gradually subsided and completely stopped within a few days. After three-week therapy with adalimumab, capsule endoscopy showed several healing ulcers without bleeding in the distal to the terminal ileum. She continues to be treated with adalimumab, azathioprine, and mesalazine without recurrent bleeding.

| :: Introduction|| |
Behçet's disease is a disorder consisting of recurrent attacks of acute inflammation and is characterized by recurrent oral and genital ulcers, uveitis, and skin lesions. Major gastrointestinal (GI) bleeding is a rare manifestation of Behçet's disease and usually occurs in those patients with multi-system involvement of vasculitis. GI bleeding with the involvement of the small intestine is less common in Behçet's disease, and it can be life-threatening. Despite a wide range of therapeutic options for the management of Behçet's disease described in the literature, the efficacy of those available therapies for small intestinal lesions is not well established. We herein report a rare presentation of Behçet's disease in a 27-year-old woman who suffered from massive small intestinal bleeding with hypovolemic shock. Finally, her small intestinal bleeding was treated with adalimumab (ADA) successfully.
| :: Case History|| |
A 27-year-old woman with a known history of Behçet's disease was admitted due to skin rashes for one week. The patient was diagnosed with Behçet's disease in 2020, with initially presented as multiple pustule formations in multiple areas of the body, panuveitis, oral and genital ulcers, and erythema nodosum. From 2020 to 2021, her Behçet's disease was treated with oral prednisolone, cyclosporine, and colchicine, and her symptoms were completely resolved. One week before this hospitalization, she suffered skin rashes over her neck, back, chest, and lower abdominal area. She also complained of sore throat, oral ulcer, and perineal ulcer. The intravenous steroid was prescribed to her after hospitalization. Four days after hospitalization, however, the patient had massive bloody stools with hypovolemic shock. Her hemoglobin level declined from 12.0 g/dL to 10.2 g/dL, and her systolic blood pressure dropped to 80 mmHg. Emergency abdominal computed tomography-angiography showed no contrast medium extravasation in the GI tract. She subsequently was transferred to our intensive care unit.
At our intensive care unit, an esophagogastroduodenoscopy was performed and failed to detect the bleeding source. We subsequently performed a colonoscopy, which showed multiple deep and large volcano-shaped ulcers with active bleeding in the terminal ileum [[Figure 1]a, arrow]. Then, we performed epinephrine injection and hemoclips for hemostasis. In addition, endoscopic biopsies from these small bowel ulcers were performed. Behçet's disease with small bowel involvement complicated with massive GI bleeding was diagnosed. Histopathology of biopsy specimens from small bowel ulcers demonstrated ulcers with the presence of vasculitis [[Figure 2], arrows]. However, bloody stools still appeared after endoscopic hemostasis. Thus, we prescribed a loading dose of 160 mg adalimumab (ADA) on week 0 followed by 80 mg ADA on week 2 subcutaneous injections to the patient. Three weeks later, the patient received a capsule endoscopy after a stable hemodynamic status. Capsule endoscopy revealed healing of previous small intestinal ulcers with a hemoclip in the terminal ileum [[Figure 1]b, arrow]. Her symptoms substantially improved after the treatment of ADA. She totally received three doses of induction therapy of ADA. The patient was asymptomatic on subsequent visits. A follow-up colonoscopy performed 6 months after the first infusion of ADA showed marked endoscopic remission of small intestinal ulcers in the terminal ileum [[Figure 1]c, arrow].

| :: Discussion|| |
Gastrointestinal manifestations of Behçet's disease are of particular importance as they are associated with morbidity and mortality. GI manifestations often occur 4.5–6 years after the onset of oral ulcers. The most common symptoms include abdominal pain, nausea, vomiting, diarrhea, and GI bleeding. Although ileocecal involvement is most commonly described, Behçet's disease may involve any segment of the GI tract and the various GI organs. The prevalence of GI involvement of Behçet's disease is relatively high in Taiwan (31.8%). It is worth mentioning that symptoms of Behçet's disease in the GI tract are diverse, making it hard to differentiate between intestinal Behçet's disease and Crohn's disease. However, the presence of vasculitis signs such as non-specific inflammation, necrotizing arterioles, and lack of granulomatous lesions of the ulcers helps in the differential diagnosis of Behçet's disease.
Treatment of intestinal Behçet's disease is difficult because there are no internationally accepted or standardized treatment strategies. It has been analyzed that the cumulative rates of surgical intervention are 20% at 1 year, 27–33% at 5 years, and 31–46% 10 years after diagnosis., Nevertheless, the rate of recurrence after a surgical procedure was estimated at 40%–87.5%. In addition, infection and complications are not uncommon in patients with Behçet's disease after surgery. Generally, the same classes of medications that have been used for the treatment of systemic Behçet's disease have also been used to treat intestinal Behçet's disease, including colchicine, 5-aminosalicylic acids (5-ASA), corticosteroids, and immunomodulators such as azathioprine, interferon-α, and anti-TNF-α agents. Otherwise, anti-TNF-α agents, including infliximab (IFX) and ADA, are also beneficial in patients with Behçet's disease who are unresponsive to conventional therapies. There are few randomized trials on the use of anti-TNF-α agents in patients with intestinal Behçet's disease. The first patient with Behçet's disease treated with infliximab was reported in 2001. A Korean retrospective multicenter study showed 28 cases of patients with intestinal Behçet's disease refractory to conventional medical treatment treated with IFX, with a clinical response rate of 64.8% at four weeks. Maintenance of infliximab treatment has shown to be more beneficial than short-term treatment for maintaining remission in patients with intestinal Behçet's disease. A Japanese consensus proposed that in patients with severe symptoms (i.e. abdominal pain, diarrhea, GI bleeding) and complications with deep ulcers confirmed by radiology or endoscopy, corticosteroids should be considered for induction therapy. In patients with mild activity, 5-ASA could be effective for induction therapy for intestinal Behçet's disease. For more severe cases of Behçet's disease, they can be treated with azathioprine. Recently, adalimumab has successfully been used as a first-line anti-TNF-α agent in patients with steroid-dependent intestinal Behçet's disease to induce and maintain complete remission. Although there is proven efficacy of anti-TNF-α agents in intestinal Behçet's disease, further randomized and prospective trials are still necessary to confirm these findings.
| :: Conclusions|| |
This report on Behçet's disease involving a small bowel should serve as a reminder of the possibility of biological treatment and highlight the importance of timely intervention to prevent complicated conditions associated with this disease. Anti-TNF-α agent appears to be promising for those patients who are resistant to conventional therapy. However, further clinical trials are needed to support their use. The identification of which population of patients with Behçet's disease may benefit from biologics is still controversial.
