Combining infliximab, anti-MAP and hyperbaric oxygen therapy for resistant fistulizing Crohn’s disease.

Fistulizing Crohn’s disease (CD) presents a therapeutic challenge as fistulae are notoriously difficult to heal. Mycobacterium avium ss paratuberculosis (MAP) treatment in CD is gaining attention. We evaluated healing of CD fistula(e) using a novel combination therapy. Nine consecutive patients who failed to heal fistulae on conventional treatment including anti-TNF, were treated with at least three doses of infliximab, 18-30 courses of hyperbaric oxygen therapy and anti-MAP antibiotics comprising rifabutin, clarithromycin and clofazimine. All patients achieved complete healing of fistulae by 6-28 weeks and follow-up for mean 18 months.

Enhanced colonic nitric oxide generation and nitric oxide synthase activity in ulcerative colitis and Crohn’s disease

Recent studies have suggested that nitric oxide (NO.), the product of nitric oxide synthase in inflammatory cells, may play a part in tissue injury and inflammation through its oxidative metabolism. In this study the colonic generation of oxides of nitrogen (NOx) and nitric oxide synthase activity was determined in ulcerative colitis and Crohn’s disease. Colonic biopsy specimens were obtained from inflammatory bowel disease patients and from normal controls. Mucosal explants were cultured in vitro for 24 hours and NOx generation was determined. Nitric oxide synthase activity was monitored by the conversion of [3H]-L-arginine to citrulline. Median NOx generation by inflamed colonic mucosa of patients with active ulcerative colitis and Crohn’s colitis was 4.2- and 8.1-fold respectively higher than that by normal human colonic mucosa. In ulcerative colitis and Crohn’s colitis nitric oxide synthase activity was 10.0- and 3.8-fold respectively higher than in normal subjects.

Role of immunosuppressives in special situations: perianal disease and postoperative period.

Complex perianal disease is associated with poor outcome and requires early effective therapy. Corticosteroids are not effective in perianal fistulising Crohn’s disease, and antibiotics, immunosuppressants and anti-TNF therapy are required. It is important to consider combined medical surgical therapy after accurate imaging using an MRI scan of the pelvis. Drainage of any abscess at examination under anaesthesia and seton insertion are important before introduction of immunosuppressants and anti-TNF therapy. Long-term follow up of patients in a single centre reported responders to azathioprine having a reduced risk of perianal surgery (OR = 0.36; 95% CI: 0.27-0.46), but complex perianal fistulising Crohn’s disease generally requires combination therapy with anti-TNF and azathioprine.

Systematic review: The safety and efficacy of hyperbaric oxygen therapy for inflammatory bowel disease.

Hyperbaric oxygen therapy (HBOT) provides 100% oxygen under pressure, which increases tissue oxygen levels, relieves hypoxia and alters inflammatory pathways. Although there is experience using HBOT in Crohn’s disease and ulcerative colitis, the safety and overall efficacy of HBOT in inflammatory bowel disease (IBD) is unknown. To quantify the safety and efficacy of HBOT for Crohn’s disease (CD) and ulcerative colitis (UC). The rate of adverse events with HBOT for IBD was compared to the expected rate of adverse events with HBOT. MEDLINE, EMBASE, Cochrane Collaboration and Web of Knowledge were systematically searched using the PRISMA standards for systematic reviews. Seventeen studies involving 613 patients (286 CD, 327 UC) were included.

Efficacy of hyperbaric oxygen in patients with Crohn’s disease: two case reports.

Crohn’s disease is an inflammatory disease of the gastrointestinal tract, usually involving the ileum, that can lead to debilitating symptoms of abdominal pain, diarrhea and malabsorption during acute exacerbations. Because there is no known cause of the illness, treatment is based upon symptomatology and may ultimately require bowel resection if response to medical therapy is inadequate. Treatment with hyperbaric oxygen has shown promise in the reduction of inflammation associated with acute exacerbations of Crohn’s disease, with alleviation of symptoms and an improvement in quality of life. We present two cases of pediatric patients with exacerbations of Crohn’s disease who underwent cycles of hyperbaric oxygen therapy.

A favourable response to surgical intervention and hyperbaric oxygen therapy in pyoderma gangrenosum.

Pyoderma gangrenosum (PG) is a neutrophilic dermatosis characterised with ulcerations. Inflammatory bowel diseases (ulcerative colitis and Crohn’s disease) and haematologic diseases (leukaemia, preleukaemia and monoclonal gammopathy) have been reported in about 40-50% of PG patients in whom the treatment of the underlying disease is important for the improvement of the lesions. We herein report a colorectal adenocarcinoma patient with PG, who responded partially to topical treatments and systemic immunosuppressants and healed completely with the aid of surgical wound repair and hyperbaric oxygen therapy.

[Hyperbaric oxygen in the treatment of perineal Crohn’s disease era of infliximab: a renewal interest?].

Despite the growing number of therapeutic methods and the recent introduction of new drugs more active in the therapeutic arsenal, lesions of the ano-perineal Crohn’s disease remains difficult to support. Hyperbaric oxygen (HBO) was made before the era of infliximab, an interesting therapeutic approach in which the current position remains unclear. To assess HBO efficacy in the treatment of anal fistulas refractory Crohn’s disease. Literature review. Hyperbaric oxygen therapy was used in the 90’s when the biotherapy was not part of the armamentarium for Crohn’s disease. Research conducted has identified only nine publications evaluating the efficacy of hyperbaric oxygen therapy in the treatment of anal fistulas refractory Crohn’s disease.

HBOT for inflammatory bowel disease

Traditionally, hyperbaric oxygen treatment (HBOT) has been used to treat a limited repertoire of disease, including decompression sickness and healing of problem wounds. However, some investigators have used HBOT to treat inflammatory bowel disease (IBD), including Crohn’s disease and ulcerative colitis.

Comprehensive searches were conducted in 8 scientific databases through 2011 to identify publications using HBOT in IBD. Human studies and animal models were collated separately.
