tacrolimus and Pouchitis

Restorative proctocolectomy with ileal pouch anal anastomosis (IPAA) is considered the procedure of choice in patients with ulcerative colitis (UC) refractory to medical therapy. The incidence of pouchitis is 40% at 5 years. Ten to 15% of patients with pouchitis experience chronic pouchitis.. To determine the efficacy of medical therapies for the treatment of chronic refractory pouchitis in patients undergoing IPAA for UC.. A systematic computer-assisted search of the on-line bibliographic database MEDLINE and EMBASE was performed between 1966 and February 2016. All original studies reporting remission rates following medical treatment for chronic pouchitis were included. All study designs were considered. Remission was defined according to the individual study. Remission endpoints ranged from 15 days to 10 weeks. Chronic pouchitis was defined by each study.. Twenty-one papers were considered eligible. Results from all studies combined suggested that overall remission was obtained in 59% of patients (95% CI: 44-73%). Antibiotics significantly induced remission in patients with chronic pouchitis with 74% remission rate (95% CI:56-93%), (P < 0.001). Biologics significantly induced remission in patients with chronic pouchitis with 53% remission rate (95% CI:30-76%), (P < 0.001). Steroids, bismuth, elemental diet and tacrolimus all can induce remission but failed to achieve significance. Faecal microbiota transplantation in a single study was not found to achieve remission.. Treatment of chronic refractory pouchitis remains difficult and is largely empirical. Larger randomised controlled trials will help aid the management of chronic pouchitis.

Pouchitis is the most common complication after restorative proctocolectomy for ulcerative colitis, and it leads to pouch failure. The administration of oral antibiotics is the main treatment for pouchitis; however, in some cases, antibiotic-refractory pouchitis may develop, which requires further medical therapy.. We investigated the applicability of topical tacrolimus for refractory pouchitis.. We performed a prospective pilot study. The study protocols were registered with the University Hospital Medical Information Network Clinical Trials Registry, 000006658.. This study was conducted in the Surgical Department of Hyogo College of Medicine.. Patients with antibiotic-refractory pouchitis were treated for 8 weeks with a tacrolimus enema.. The efficacy was assessed by comparing Pouchitis Disease Activity Index scores. Safety was assessed by measuring whole blood tacrolimus trough levels.. Ten patients with refractory pouchitis were enrolled. No severe adverse events occurred. The mean scores decreased from 15.9 ± 0.8 to 7.8 ± 0.8 during 8 weeks of treatment (p < 0.01). Specifically, the clinical symptom, endoscopic finding, and histological finding subscores decreased to 0.8 ± 0.6, 3.9 ± 0.2, and 2.9 ± 0.4. Nine patients recovered from their clinical symptoms, and 3 patients recovered from pouchitis.. This small study was neither blinded nor randomized.. This study demonstrates that the use of topical tacrolimus for the treatment of refractory pouchitis is safe and effective in the short term for clinical symptoms. Although complete endoscopic healing was not achieved, this treatment may have early rescue efficacy in the treatment of antibiotic-refractory pouchitis.

Tacrolimus (FK506) is widely used in the organ transplant setting, but not in the treatment of IBD.. the aim of this study was to analyse the effectiveness of tacrolimus in specific clinical presentations of inflammatory bowel disease (IBD) in which recurrence is likely.. inclusion criteria were: perianal Crohn's disease (PCD), CD in rectal stump, pouchitis and cuffitis with severely impaired function of the ileoanal pouch (IPAA), and proven refractoriness to other therapies. Clinical assessment: Hughes' classification (PCD); Oresland index (OI) in IPAA, endoscopy-biopsy and Quality of life (QoL) using the Spanish version of the IBDQ. Response was determined as complete (CP), partial (PR) or non-existent (NR). Tacrolimus was administered orally at a dose of 0.1 mg/kg/day (levels 5-15 .g/L).. nineteen patients entered the study. Mean duration of treatment was 9.6 +/- 6.3 months. In PCD, CR was reported in 66% of cases and PR in 33%, with disappearance of inflammation, stenosis and ulcers. In patients with pouchitis and cuffitis,77% presented either CR or PR. The OI scores and QoL improved significantly after treatment (p<0.006 and p<0.002, respectively). Adverse effects were minor and controlled by regulating the dose.. oral administration of tacrolimus is easy to per-form and has few adverse effects when used to treat IBD in certain clinical presentations with a high likelihood of recurrence.

Local rectal application of tacrolimus in distal colitis, pouchitis and perianal Crohn's disease has previously been reported to be both effective and safe. We report a patient treated with per rectum local application of tacrolimus, who developed toxic levels of tacrolimus and acute renal injury during an episode of acute gastroenteritis. This case illustrates that local application of tacrolimus, although usually safe, may be associated with significantly raised tacrolimus levels and acute renal injury during acute gastroenteritis. It is important for physicians to be aware of this association when prescribing local rectal tacrolimus.

This study aimed to evaluate the efficacy of oral tacrolimus in patients with inflammatory bowel disease (IBD) refractory to conventional therapy, including azathioprine, 6-mercaptopurine, and infliximab.. Retrospective review of all patients with IBD treated with oral tacrolimus was undertaken. Tacrolimus was administered t an initial dose of 0.05 mg/kg twice daily, aiming for serum trough levels of 5-10 ng/mL. We evaluated clinical response, a retrospective estimated Crohn's disease activity index (CDAI) for Crohn's disease (CD), modified Truelove-Witts index for ulcerative colitis (UC), and modified pouch disease activity index (mPDAI) for pouchitis. Patients had been monitored clinically for benefit and side effects and by whole blood tacrolimus level approximately every 4 weeks for the duration of treatment. Clinical remission was defined as an estimated CDAI <150 (CD), an inactive disease score on the Truelove-Witts index (UC), and mPDAI <5 (pouchitis).. Twelve patients with CD, six with UC, and one with pouchitis, all resistant to previous therapies, were treated for a median of 5 months. After 4 weeks 10 CD (83%), four UC (67%) patients, and one pouchitis patient had a clinical response. There was a median reduction of the estimated CDAI of 108 points (range 35-203; P = 0.002) and stool frequency of three per day at week 4. Remission was achieved in 42% (5/12) of CD and 50% (3/6) of UC patients at the end of follow-up. Side effects included temporary elevated creatinine (n = 1), tremor (n = 3), arthralgia (n = 1), insomnia (n = 1), and malaise (n = 1). Four patients discontinued treatment due to side effects. CONCLUSION-: Oral tacrolimus is well tolerated and effective in patients with refractory IBD in the short- to medium-term. Further controlled, long-term evaluation is warranted.

We and others have reported the use of tacrolimus in refractory inflammatory bowel disease (IBD). Little is known about its long-term efficacy and safety.. In this retrospective, observational single center study the charts of 53 adult patients with steroid-dependent (n = 18) or steroid-refractory (n = 35) IBD, Crohn's disease (CD) (n = 11), ulcerative colitis (UC) (n = 40), or pouchitis (PC) (n = 2) were reviewed. Tacrolimus (0.1 mg/kg body weight per day) was administered orally in all and initially intravenously in 2 patients (0.01 mg/kg body weight per day), aiming for serum trough levels of 4-8 ng/mL. Forty-one of 53 (77.1%) patients were receiving concomitant azathioprine. The mean treatment duration was 25.2 +/- 4.6 SD months (0.43-164 months). Patients were followed for a mean of 39 +/- 4.1 SD months (5-164 months). Response was evaluated using a modified clinical activity index (M-CAI).. Thirty-one UC (78%), 10 CD (90.1%), and both PC (100%) patients experienced an immediate clinical response or went into remission at 30 days. A statistically significant drop on the M-CAI was documented for UC and CD patients. Nine UC patients (22.5%) underwent colectomy between 1.6 and 41.3 months following initiation. Mean colectomy-free survival was 104.8 +/- 15.5 (95% CI 74.4-135.2) months (limited to 164.4 months). Cumulative colectomy-free survival was estimated 56.5% at 43.8 months. Steroids were reduced or discontinued in 40 of 45 UC and CD patients (90%) taking steroids. Side effects included a temporary rise of creatinine (n = 4, 7.6%), tremor or paresthesias (n = 5, 9.4%), hyperkalemia (n = 1, 1.9%), hypertension (n = 1, 1.9%), and opportunistic infections (n = 2, 3.8%).. Long-term tacrolimus therapy appears safe and effective in refractory IBD.
