Letter Restorative proctocolectomy with ileal pouch anal anastomosis [IPAA] is the treatment of choice in patients with refractory ulcerative colitis [UC].1 A challenging situation in up to 10% of IPAA patients is recurrent or refractory pouchitis.2 Some alternative immunosuppressive therapy options are successful.2 A subset of patients with IPAA may develop Crohn’s disease [CD] or a Crohn’s disease–like condition of the pouch. Therapeutic management of this situation can be challenging. Tran-Minh et al. presented two patients with clinical remission under ustekinumab [UST] therapy.3 We would like to report another patient with suspected CD-like chronic pouchitis with bloody diarrhea, refractory to fecal microbiota transplantation [FMT], anti-TNF therapies and continued steroids. A 40-year-old male patient with bloody diarrhea was diagnosed with UC in 2005. Steroid therapy was initiated. In the further course, a chronic active UC developed, and medication with azathioprine had to be stopped due to pancreatitis as a side effect of azathioprine. Biologics therapy involving infliximab, adalimumab and vedolizumab did not achieve remission. Even treatment with leukocyte apheresis did not reduce the disease activity. Therefore, in January 2015, a colectomy and IPAA was performed. In the further course stenosis of the anastomosis and refractory pouchitis occurred. Various antibiotic treatments did not lead to any improvement, but surgical complications in the form of fistulae or abscesses were excluded. Four FMTs in an interval of 4 weeks failed to produce clinical improvement. Due to the therapy-resistant pouchitis, including failure of antibiotic treatment, FMT, and a steroid-dependent course, and additionally on the basis of an endoscopic image indicating mucosal erythema, ulcerations, loss of vascular pattern, and granularity of pouch mucosa, induction therapy with UST in combination with 50 mg prednisolone was initiated in April 2017 [Week 0]. At this time, the histology assumed a CD-like disease in the pouch and neoterminal ileum. No NOD2 mutations [rs2066844, rs2066845 or rs2066847] were found. After initiation of UST 390 mg parenterally at Week 0, the patient was followed up as an outpatient every 4 weeks. He reported improvement in clinical symptoms at Week 4. Frequency of defecation decreased from 20 bowel movements to 8–10/day without blood or mucus. Pouchoscopy on Week 8 demonstrated significant improvement [Figure 1]. Serum CRP and fecal calprotectin in the stool also normalized on repeated testing. After 6 months, prednisolone was able to be reduced to 5 mg per day. Figure 1.

B1 and B2 show the histological aspects of chronic inflammation featuring CD-like disease. Figure 1.

B1 and B2 show the histological aspects of chronic inflammation featuring CD-like disease. The etiology of pouchitis is still not fully understood. Therapy, especially therapy of chronic pouchitis, remains challenging. In an earlier case series, we showed beneficial effects with FMTs in three out of five patients, and our report suggests that UST might be a treatment option worthy of consideration.4 Clinical trials are warranted to assess the efficacy and safety of UST in this patient group.
