Abstract: PURPOSE OF REVIEW: For patients who require colectomy, the ileal pouch anal anastomosis operation has alleviated the need for permanent ileostomy and has improved associated self-esteem issues. The most common complication of this surgery, however, is pouchitis. This review highlights the most recent research in the pathophysiology, risk factors, diagnosis and management of pouchitis, and pouch surveillance for neoplasia in patients who had ulcerative colitis. RECENT FINDINGS: Markers of inflammation, including fecal lactoferrin and mucosal cytokines, have been reported as useful in differentiating between irritable pouch syndrome and pouchitis. Numerous risk factors for the development of pouchitis have been identified. They include the presence of perinuclear antinuclear cytoplasmic antibodies, steroid use prior to colectomy, dysplasia as the indication for colectomy, the presence of extraintestinal manifestations, and an elevated platelet count. Therapy for acute pouchitis remains a short course of antibiotics. For chronic pouchitis, studies found success with rifaximin, tinidazole, and oral budesonide. Cancer in the residual rectal mucosa, in the ileal mucosa, and in pouch polyps occurs frequently enough to warrant surveillance. SUMMARY: Risk factors for the development of pouchitis should be discussed with patients. Less invasive diagnostic strategies have been proposed and antibiotics are still the mainstay of therapy.

Abstract: Pancolitis affects approximately 20% to 40% of the total ulcerative colitis population and remains a therapeutic challenge for clinicians. Practitioners must focus on pancolitis when evaluating a patient for ulcerative colitis, because pancolitis is associated with more severe and fulminant disease and a higher rate of colorectal cancer and colectomy. It is imperative for clinicians to be knowledgeable in the clinical course, medications, and appropriate manner to induce and maintain clinical remission to prevent serious sequelae of the disease. The purpose of this article is to provide a review of the treatment of pancolitis for general gastroenterologists, because medical management decisions have life-long effects for this subgroup of patients.

Abstract: The idiopathic inflammatory bowel diseases, ulcerative colitis and Crohn's colitis, are associated with an increased risk for developing colorectal cancer. To reduce colorectal cancer mortality in inflammatory bowel disease, most patients and their physicians choose to follow a program of surveillance colonoscopy in an attempt to detect early neoplastic lesions at a curable stage. Colectomy is typically reserved for patients whose biopsy findings are indicative of heightened cancer risk based on interpretation by pathologists. Despite the absence of prospective controlled clinical trials to formally evaluate the benefits, risks, and costs of this approach, enough circumstantial evidence has accrued to warrant its widespread adoption in practice. Nevertheless, no standardized guidelines have yet been set forth to guide the gastroenterologist in performing surveillance. A panel of international experts was assembled to develop consensus recommendations for the performance of surveillance. The findings are presented herein.

Abstract: Ulcerative colitis (UC) and Crohn's disease (CD), collectively known as inflammatory bowel disease (IBD), afflict an estimated one million Americans and produce symptoms that impair quality of life and ability to function. Progress in IBD management strategies has led to optimized approaches for achieving the two primary clinical goals of therapy: induction and maintenance of remission. Although surgery is indicated to treat refractory disease or specific complications, pharmacotherapy is the cornerstone of IBD management. The efficacy of aminosalicylates for induction of remission in mild to moderate UC and CD is well established, as is their role for maintenance of remission in UC. The sulfa-free mesalamine formulation offers an adverse effect profile similar to that of placebo, enabling the administration of higher, more effective doses. Although corticosteroids provide potent anti-inflammatory effects, their benefits are countermanded by the risk of intolerable and serious adverse effects, and they are ineffective for maintenance therapy. Other agents effective in inducing or maintaining remission are azathioprine, 6-mercaptopurine, infliximab, cyclosporine, methotrexate, and antibiotics. Ongoing clinical trials of experimental therapies will generate new tools for IBD treatment. Currently, a broad range of options allows physicians to tailor treatment to each patient's needs and preferences. Such considerations are essential for maximizing adherence to therapy.

Abstract: This review covers the use of steroids in the treatment of both ulcerative colitis and Crohn's disease. It looks at controlled trials and uncontrolled trials as to the benefits of this agent in both inducing and maintaining remission. The review also stresses the high incidence of toxicity with prolonged use of steroids and the fact that controlled trials have clearly shown that steroids do not maintain remission in either disorder. Alternatives to initiating steroids in mild to moderately active ulcerative colitis and Crohn's disease are presented. The use of steroids in fistulizing versus nonfistulizing Crohn's is also covered. Finally, there is a review of data and discussion of the role of antibiotics, immunosuppressives, and combination therapy for both ulcerative colitis and Crohn's disease. The expectation is that the reader will consider alternatives to initiating and maintaining steroids for prolonged periods of time in the treatment of inflammatory bowel disease.

Abstract: BACKGROUND: Repifermin (keratinocyte growth factor-2) has been shown to reduce inflammation in animal models of colitis. AIM: To evaluate repifermin for the treatment of active ulcerative colitis. METHODS: Eighty-eight patients with active ulcerative colitis were enrolled in a 6-week, double-blind trial. Patients were randomized to receive treatment for five consecutive days with intravenous repifermin at a dose of 1, 5, 10, 25 or 50 microg/kg, or placebo. The primary objective of the study was to evaluate the safety of repifermin. The primary efficacy outcome was clinical remission at week 4, defined as a score of zero on the endoscopic appearance and stool blood components of the Mayo score and a score of zero or unity on the stool frequency and physician's global assessment components. RESULTS: At week 4, the rates of clinical remission in the 1, 5, 10, 25 and 50 microg/kg repifermin groups were 19%, 9%, 0%, 0% and 0%, respectively, and 11% for the placebo group (P = 0.32 for repifermin vs. placebo). The frequencies of commonly occurring adverse events and severe adverse events were similar in both groups. CONCLUSIONS: Intravenous repifermin at a dose of 1-50 microg/kg was very well tolerated, but there was no evidence that repifermin was effective for the treatment of active ulcerative colitis at these doses. An additional study to determine the efficacy of repifermin at doses of > 50 microg/kg or for a longer treatment duration may be warranted, as the maximally tolerated dose was not reached in the present study.

Abstract: BACKGROUND & AIMS: In patients with severe corticosteroid-refractory ulcerative colitis, cyclosporine or infliximab may be added in an effort to induce remission. If the patient then fails either of these drugs, it is unknown whether success can be achieved by using the other agent. The aim of this study was to assess outcomes of using cyclosporine after failure of infliximab, and vice versa. METHODS: We retrospectively reviewed the charts of 19 patients with corticosteroid-refractory ulcerative colitis who received either infliximab after failed cyclosporine or cyclosporine after failed infliximab. Acute salvage therapy was defined as having received the alternate drug within 4 weeks of discontinuing the first agent. RESULTS: Ten patients received infliximab after failing cyclosporine; 9 patients received cyclosporine after failing infliximab. Four patients (40%) in the infliximab-salvage group achieved remission, as did 3 (33%) in the cyclosporine-salvage group. Remission lasted a mean of 10.4 months (range, 4.4-17.03 mo) and 28.5 months (range, 5.0-41.5 mo), respectively. Severe adverse events included one patient who developed sepsis and died after receiving infliximab salvage. One patient who received cyclosporine salvage developed herpetic esophagitis, and another patient who received cyclosporine salvage developed pancreatitis and bacteremia. CONCLUSIONS: In patients with severe corticosteroid-refractory ulcerative colitis who fail treatment with either cyclosporine or infliximab, remission rates using acute salvage therapy by crossing over to the other drug occur in approximately one third of patients and have limited duration. Serious adverse events occurred in 16%, including 1 death, suggesting that the risks of acute salvage therapy may outweigh the benefits.

Abstract: OBJECTIVES: Patients with extensive, longstanding chronic ulcerative or Crohn's colitis face greater risks of developing colorectal cancer. Current standard surveillance relies on detecting dysplasia using random sampling at colonoscopy but may fail to detect dysplasia in many patients. Dye spraying techniques have been reported to aid in detecting otherwise subtle mucosal abnormalities in the setting of colitis. We prospectively compared dye-spray technique using methylene blue to standard colonoscopic surveillance in detecting dysplasia. METHODS: One hundred fifteen patients were referred to the Chromoendoscopy Study Group and prospectively screened for the study. One hundred two (64 M, 38 F) (79 UC 23 CC) patients meeting the inclusion criteria were enrolled. Following a standard bowel preparation, each patient was examined using standard office endoscopic equipment by three methods: (a) standard surveillance colonoscopy with four random biopsies every 10 cm (for a total of at least 32 samples); (b) a targeted biopsy protocol; and finally (c) methylene blue (0.01%) dye spray was segmentally applied throughout the colon and any pit-pattern abnormality or lesion rendered visible by the dye spray was targeted and biopsied. Each patient had a single examination, which included two passes of the colonoscope. Specimens were reviewed in a blinded fashion by a single gastrointestinal pathologist. The three methods were then compared with each patient serving as his or her own control. RESULTS: Targeted biopsies with dye spray revealed significantly more dysplasia (16 patients with low grade and 1 patient with high grade) than random biopsies (3 patients with low-grade dysplasia) (P= 0.001) and more than targeted nondye spray (8 patients with low-grade and 1 patient with high-grade dysplasia) (P= 0.057). Targeted biopsies with and without dye spray detected dysplasia in 20 patients compared with 3 using Method (a) (P= 0.0002, two-tailed exact McNemar's Test). There were no adverse events. CONCLUSIONS: Colonoscopic surveillance of chronic colitis patients using methylene blue dye-spray targeted biopsies results in improved dysplasia yield compared to conventional random and targeted biopsy methods. Accordingly, this technique warrants incorporation into clinical practice in this setting and consideration as a standard of care for these patients. The value of multiple random biopsies as a surveillance technique should be revisited.

Abstract: BACKGROUND: There are few studies that describe the medical treatment and colitis response rates among patients with a severe relapse of inflammatory bowel disease (IBD) during pregnancy, and few studies of the effect of such a relapse on birth outcomes in these patients. OBJECTIVES: To describe the treatment and response rates of severe colitis in pregnancy, and to assess the effects of a severe relapse of colitis during pregnancy on birth outcomes. METHODS: We performed a case control study of pregnant patients with IBD hospitalized for a disease relapse at two large treatment centers between 1989 and 2001. Details of management of disease relapse and maternal and fetal outcomes were recorded. RESULTS: Eighteen patients (11 ulcerative colitis, 6 Crohn's disease, 1 indeterminate colitis), mean age 28.6 yr (range 19-38) formed the study group; 41 age-matched pregnant IBD patients without disease relapse formed the control group. Study patients were hospitalized at a mean of 15.9-wk gestation (range 8-35) for a mean of 10.4 days (range 3-31). All 18 patients received IV hydrocortisone (mean dose 199 mg/day) and 7 patients (39%) either continued taking or were commenced on immunomodulators: IV cyclosporine (5 patients) and azathioprine/6-MP (3 patients). Fifteen patients (83%) had a clinical response to these medical treatments, 3 patients required colectomy. There were significant differences between study and control groups in gestation period (35.0 wk vs 38.7 wk, respectively, P= 0.0001) and birth weight (2,001 g vs 3,018 g, respectively, P < 0.0001). CONCLUSIONS: Treatment with IV hydrocortisone and IV cyclosporine appears effective at inducing remission of colitis but their use must continue to be confined to severely ill patients being treated at specialized centers. Severe relapses of colitis during pregnancy increase the risk of preterm birth and low birth weight.

Abstract: BACKGROUND & AIMS: Thiazolidinedione ligands for the gamma subtype of peroxisome proliferator-activated receptors (PPARgamma), widely used to treat type 2 diabetes mellitus, have been proposed as novel therapies for ulcerative colitis (UC). METHODS: This multicenter, randomized, double-blind, placebo-controlled clinical trial compared the efficacy of rosiglitazone (Avandia; GlaxoSmithKline, Philadelphia, PA) 4 mg orally twice daily vs placebo twice daily for 12 weeks in 105 patients with mild to moderately active UC. Disease activity was measured with the Mayo score. The primary end point was clinical response (>/=2-point reduction) at week 12. Clinical remission (Mayo score </=2), endoscopic remission, and quality of life were secondary outcomes. RESULTS: After 12 weeks of therapy, 23 patients (44%) treated with rosiglitazone and 12 patients (23%) treated with placebo achieved clinical response (P = .04). Remission was achieved in 9 patients (17%) treated with rosiglitazone and 1 patient (2%) treated with placebo (P = .01). Endoscopic remission was uncommon in either treatment arm (8% rosiglitazone vs 2% placebo; P = .34). Clinical improvement was evident as early as 4 weeks after beginning treatment (P = .049). Quality of life was improved significantly at week 8 (P = .01), but not at week 4 (P = .48) or week 12 (P = .14). Serious adverse events were rare. CONCLUSIONS: Rosiglitazone was efficacious in the treatment of mild to moderately active UC.

Abstract: OBJECTIVES: We reviewed data to investigate the effect of 5-ASA drugs, metronidazole, ciprofloxacin, prednisone, 6-mercaptopurine, azathioprine, and cyclosporine on pregnancy outcomes in patients with inflammatory bowel disease (IBD). METHODS: One hundred and thirteen female patients with a total of 207 documented conceptions were studied. Treatment information included: smoking history (patient and spouse), dates of conception and termination, and outcome of pregnancy (spontaneous abortion, therapeutic abortion, maternal or fetal illness resulting in abortion, premature birth, healthy full-term birth, multiple births, ectopic pregnancy, congenital defects), weight of baby, type of delivery (cesarian section, vaginal), medication history during each trimester (mean dose, maximum dose, frequency). We analyzed the effect on pregnancy outcome of medication use during the first trimester or at any time during the pregnancy. RESULTS: Thirty-nine patients (34.5%) had ulcerative colitis (UC), 73 (64.5%) had crohn's disease (CD), and 1 patient (1%) had indeterminate colitis. For 100 of the 207 conceptions, the patients were on 5-ASA drugs at some time during the pregnancy, 49 on prednisone, 101 on an immunomodulator (6-MP/azathioprine), 27 on metronidazole, 18 on ciprofloxacin, and 2 on cyclosporine. In 85 (31%) of the conceptions, patients were on none of these medications. No significant differences were found among the groups in each pregnancy with respect to outcome (p values 0.091 to 0.9). In multivariate analyses controlling for age of mother, there was no evidence that 5-ASA type drugs or any type of drug influenced pregnancy outcome. CONCLUSIONS: In 113 female patients with 207 conceptions none of the drugs used to treat IBD is associated with poor pregnancy outcomes.

Abstract: An 18-year-old woman with ulcerative colitis (UC) developed diffuse pulmonary infiltrates and hypoxemia three months after reinstitution of oral mesalamine. Lung biopsy revealed bronchiolitis obliterans with interstitial pneumonitis. Clinical and radiographic abnormalities improved upon discontinuation of mesalamine and treatment with corticosteroids. This patient presented the problem of differential diagnosis of pulmonary disease associated with inflammatory bowel disease (IBD), including lesions believed to result from lung involvement secondary to IBD, as well as adverse reactions to medications. We present and analyze evidence associating mesalamine with pulmonary toxicity in this patient, but emphasize that the distinction between adverse drug reaction and extraintestinal manifestations of IBD is difficult.

Abstract: BACKGROUND: Pyoderma gangrenosum complicates inflammatory bowel disease in 2-3% of patients and often fails to respond to antibiotics, steroids, surgical debridement or even colectomy. METHODS: We performed a retrospective chart analysis of 11 consecutive steroid-refractory pyoderma patients (5 ulcerative colitis, 6 Crohn's disease) referred to our practice and then treated with intravenous cyclosporine. Pyoderma gangrenosum was present on the extremities in 10 patients, the face in 2, and stomas in 21. At initiation of intravenous cyclosporine, bowel activity was moderate in 3 patients, mild in 4, and inactive in 4. All patients received intravenous cyclosporine at a dose of 4 mg/kg/d for 7-22 days. They were discharged on oral cyclosporine at a dose of 4-7 mg/kg/d. RESULTS: All 11 patients had closure of their pyoderma with a mean time to response of 4.5 days and a mean time to closure of 1.4 months. All seven patients with bowel activity went into remission. Nine patients were able to discontinue steroids, and nine were maintained on 6-mercaptopurine or azathioprine. One patient who could not tolerate 6-mercaptopurine had a recurrence of pyoderma. No patient experienced significant toxicity. CONCLUSION: Intravenous cyclosporine is the treatment of choice for pyoderma gangrenosum refractory to steroids and 6-mercaptopurine should be used as maintenance therapy.

Abstract: BACKGROUND & AIMS: Unlike ulcerative colitis, there are few reports on the efficacy of surveillance colonoscopy in patients with chronic Crohn's colitis and therefore little agreement as to whether routine surveillance is indicated. We report on 259 patients with chronic Crohn's colitis who underwent screening and subsequent surveillance colonoscopy and biopsy since 1980. METHODS: Biopsies were performed at 10-cm intervals and from strictures and polypoid masses. Pathology was classified as normal, dysplasia (indefinite, low-grade, high-grade), or carcinoma. RESULTS: A total of 663 examinations were performed on 259 patients. The median interval between examinations was 24 months; examinations were performed more frequently (1-6 months) in patients with dysplasia on biopsy. A thinner-caliber colonoscope was required to complete 12% of screening examinations and 23% of surveillance examinations. The pediatric colonoscope helped increase our yield of neoplasia by 19%. The screening and surveillance program detected dysplasia or cancer in 16% (10 indefinite, 23 low-grade, and 4 high-grade dysplasias and 5 cancers). A finding of definite dysplasia or cancer was associated with age >45 years and increased symptoms. By life table analysis, the probability of detecting dysplasia or cancer after a negative screening colonoscopy was 22% by the fourth surveillance examination. CONCLUSIONS: Colonoscopic surveillance should be strongly considered in chronic extensive Crohn's colitis.

Abstract: BACKGROUND & AIMS: Adenomatous polyps are by definition dysplastic and pathologically indistinguishable from the dysplasia-associated lesion or mass (DALM) described in 1981. Yet, adenomatous polyps in noncolitic colons are usually removed definitively endoscopically, whereas DALMs are regarded as harbingers of colon cancer, mandating colectomy. METHODS: Since 1988, all of our patients with chronic ulcerative or Crohn's colitis and dysplastic polyps and no coexistent dysplasia in flat mucosa underwent colonoscopic polypectomy. Biopsy specimens were obtained also adjacent to polypectomy sites, from strictures, and throughout the colon at 10-cm intervals. Follow-up colonoscopies and biopsies were performed within 6 months after polypectomy and yearly thereafter. RESULTS: Colonoscopy in 48 patients with chronic colitis (mean duration, 25.4 years) resected 70 polyps (60 in colitic and 10 in noncolitic mucosa). Polyps were detected on screening colonoscopies (29%) and on surveillance (71%). Pathology was tubular adenoma in all polyps from noncolitic mucosa and low-grade dysplasia (57), high-grade dysplasia (2), or carcinoma (1) in polyps from colitic mucosa. Subsequent colonoscopies (mean follow-up, 4.1 years) revealed additional polyps in 48% but no carcinomas. Surgical resection (6 patients) for recurrent polyps confirmed colonoscopic findings. No dysplasia or cancers in flat mucosa were found at surgery or on follow-up colonoscopies. CONCLUSIONS: In patients with chronic colitis who have no dysplasia in flat mucosa, colonoscopic resection of dysplastic polyps can be performed effectively, just as in noncolitic colons.
