The 2023 Impact of Inflammatory Bowel Disease in Canada: Treatment Landscape.

The therapeutic landscape for inflammatory bowel disease (IBD) has changed considerably over the past two decades, owing to the development and widespread penetration of targeted therapies, including biologics and small molecules. While some conventional treatments continue to have an important role in the management of IBD, treatment of IBD is increasingly moving towards targeted therapies given their greater efficacy and safety in comparison to conventional agents. Early introduction of these therapies-particularly in persons with Crohn's disease-combining targeted therapies with traditional anti-metabolite immunomodulators and targeting objective markers of disease activity (in addition to symptoms), have been shown to improve health outcomes and will be increasingly adopted over time. The substantially increased costs associated with targeted therapies has led to a ballooning of healthcare expenditure to treat IBD over the past 15 years. The introduction of less expensive biosimilar anti-tumour necrosis factor therapies may bend this cost curve downwards, potentially allowing for more widespread access to these medications. Newer therapies targeting different inflammatory pathways and complementary and alternative therapies (including novel diets) will continue to shape the IBD treatment landscape. More precise use of a growing number of targeted therapies in the right individuals at the right time will help minimize the development of expensive and disabling complications, which has the potential to further reduce costs and improve outcomes.

The cost of inflammatory bowel disease in high-income settings: a Lancet Gastroenterology & Hepatology Commission.

The cost of caring for patients with inflammatory bowel disease (IBD) continues to increase worldwide. The cause is not only a steady increase in the prevalence of Crohn's disease and ulcerative colitis in both developed and newly industrialised countries, but also the chronic nature of the diseases, the need for long-term, often expensive treatments, the use of more intensive disease monitoring strategies, and the effect of the diseases on economic productivity. This Commission draws together a wide range of expertise to discuss the current costs of IBD care, the drivers of increasing costs, and how to deliver affordable care for IBD in the future. The key conclusions are that (1) increases in health-care costs must be evaluated against improved disease management and reductions in indirect costs, and (2) that overarching systems for data interoperability, registries, and big data approaches must be established for continuous assessment of effectiveness, costs, and the cost-effectiveness of care. International collaborations should be sought out to evaluate novel models of care (eg, value-based health care, including integrated health care, and participatory health-care models), as well as to improve the education and training of clinicians, patients, and policy makers.

Patient Perspectives on the Long-term Management of Celiac Disease.

GOAL: The aim of this study was to survey adults with celiac disease (CD) on the utility of specific aspects of follow-up and on information needs. BACKGROUND: Currently, the treatment for CD is strict gluten avoidance. Although this places the onus on the patient for disease management, patient perspectives on CD care have not been formally assessed. STUDY: The Manitoba Celiac Disease Cohort prospectively enrolled adults newly diagnosed with CD using serology and histology. At the 24-month study visits, participants rated the utility of aspects of CD care on a 5-point scale anchored by "not at all useful" and "very useful" and the helpfulness of information on CD-related topics on a 6-point scale anchored by "not at all helpful" and "very helpful." RESULTS: The online survey was completed by 149 of 211 cohort members [median age 40 (interquartile range 30 to 56) y; 68% female]. Adherence to a gluten-free diet was good. Most participants (87%) responded that they should be seen regularly for medical follow-up of CD, preferably every 6 (26%) or 12 months (48%). Blood tests were the most highly rated care component (rated scored ≥4/5 by 78% of respondents), followed by the opportunity to ask about vitamins and supplements (50%), symptom review (47%), and information on CD research (44%). Diet review was not considered helpful. CONCLUSIONS: Two years after diagnosis, most individuals with CD find regular specialist follow-up helpful, particularly for biochemical assessment of disease activity and its complications. Furthermore, information on research and long-term complications of CD is also valued.

Crohn's and Colitis Canada's 2021 Impact of COVID-19 and Inflammatory Bowel Disease in Canada: Health Care Delivery During the Pandemic and the Future Model of Inflammatory Bowel Disease Care.

The SARS-CoV-2 pandemic has had a profound impact on inflammatory bowel disease (IBD) health care delivery. The implementation of necessary public health restrictions has restricted access to medications, procedures and surgeries throughout the pandemic, catalyzing widespread change in how IBD care is delivered. Rapid large-scale implementation of virtual care modalities has been shown to be feasible and acceptable for the majority of individuals with IBD and health care providers. The SARS-CoV-2 pandemic has exacerbated pre-existing barriers to accessing high-quality, multidisciplinary IBD care that addresses health care needs holistically. Continued implementation and evaluation of both synchronous and asynchronous eHealthcare modalities are required now and in the future in order to determine how best to incorporate these modalities into patient-centred, collaborative care models. Resources must be dedicated to studies that evaluate the feasibility, acceptability and effectiveness of eHealth-enhanced models of IBD care to improve efficiency and cost-effectiveness, while increasing quality of life for persons living with IBD. Crohn's and Colitis Canada will continue to play a major leadership role in advocating for the health care delivery models that improve the quality of life for persons living with IBD.

Trends in Corticosteroid Use During the Era of Biologic Therapy: A Population-Based Analysis.

INTRODUCTION: Corticosteroids are effective for inducing clinical remission in inflammatory bowel disease (IBD), but not for maintaining remission. Reducing corticosteroid use and dependence is an important treatment goal since their use is associated with adverse events. The extent to which the improvements in IBD therapy have led to less corticosteroid use in the modern era remains unclear. METHODS: We used the University of Manitoba Inflammatory Bowel Disease Epidemiologic Database to assess the cumulative annual dosing of corticosteroids on a per-patient basis for all persons with IBD in the province of Manitoba between 1997 and 2017. Joinpoint analysis was used to assess for trends in corticosteroid use and to look at variation in the trends over time. RESULTS: The mean annual exposure to corticosteroids decreased from 419 mg/yr (1997) to 169 mg/yr (2017) for Crohn's disease (CD) (annual decline: 3.8% per year, 95% confidence interval 3.1-4.6) and from 380 to 240 mg/yr in ulcerative colitis (UC) (annual decline: 2.5% per year, 95% confidence interval 2.1-2.8). In CD, there was an acceleration in the rate of decline after 2007 (pre-2007, 1.9% decline per year; after 2007, 5.7% per year); there was no corresponding acceleration in the rate of decline in UC. DISCUSSION: Corticosteroid use has decreased in both CD and UC over the past 2 decades, becoming more pronounced after 2007 in CD. Potential explanations include introduction and increasing penetrance of biologic therapy in CD and greater awareness of corticosteroid-related adverse events in IBD. Further work is required understand the drivers of persistent corticosteroid use in IBD and how this can be further reduced.

Nutritional implications of dietary gluten avoidance among Canadians: results from the 2015 Canadian Community Health Survey.

Adherence to a gluten-free diet (GFD) is the only available treatment for gluten-related disorders, although a GFD may also be followed for discretionary reasons. The main objectives of the present study were to (1) describe and test for differences in key nutrient intakes among Canadians who follow a GFD compared with Canadians with no dietary exclusions and (2) describe additional dietary avoidances adhered to by Canadians who avoid gluten. We conducted a secondary analysis of the cross-sectional 2015 Canadian Community Health Survey-Nutrition Survey, which included a general health survey and 24-h dietary recall (n 20 487). Participants were categorised as those who avoid dietary gluten and those who reported no avoidances. Key nutrient intakes were assessed, as a percentage of Dietary Recommended Intakes, including fibre, B vitamins, vitamin D, Ca, Fe, Na and Zn, and compared between the two groups using t tests. Canadians who avoided gluten had significantly lower intakes of folate, vitamin B12, vitamin D, Fe, Na and Ca compared with those who did not avoid any food groups. However, Canadians who reported following a GFD were significantly more likely to use vitamin or mineral supplements in the past 30 d. More than 20 % of those who avoided gluten also avoided dairy products. Findings suggest that following a GFD places Canadians at risk for nutrient inadequacies, particularly folate, Ca and vitamin D. Further research is required to further examine how multiple dietary avoidances among those who avoid gluten may contribute to dietary inadequacies.

Cost-effectiveness analysis of a fecal microbiota transplant center for treating recurrent C.difficile infection.

OBJECTIVE: We assessed the cost-effectiveness of establishing a fecal microbial transplant (FMT) unit in Canada for the treatment of recurrent CDI. DESIGN: We performed a cost-effectiveness analysis to determine the number of patients with recurrent CDI needed to treat (NNT) annually to make establishing a FMT unit cost-effective. We compared treating patients for their second recurrence of CDI with FMT in a jurisdiction with a FMT unit, compared to being treated with antibiotics; then sent to a medical center with FMT available for the third recurrence. We used a willingness to pay threshold of $50,000 per quality-adjusted-life-year gained. RESULTS: The minimum annual NNT was 15 for FMT via colonoscopy, 17 for FMT via capsule, and 44 for FMT via enema compared with vancomycin, and 16, 18, and 47 compared with fidaxomicin, respectively. A medical center's minimum catchment area when establishing a FMT unit would have to be 56,849 if using FMT via colonoscopy, or 64,429 if using capsules. CONCLUSION: We report the minimum number of patients requiring treatment annually with FMT to achieve cost-effectiveness, when including start-up and ongoing costs. FMT is cost-effective in Canada in populations with a sufficient number of eligible patients, ranging from 15 to 47 depending on the FMT modality used. This is crucial for medical jurisdictions making decisions about establishing a FMT unit for the treatment of recurrent CDI. The cost-effectiveness can be generalized in other countries.

Efficacy of iron supplementation on fatigue and physical capacity in non-anaemic iron-deficient adults: a systematic review of randomised controlled trials.

OBJECTIVE: Iron supplementation in iron-deficiency anaemia is standard practice, but the benefits of iron supplementation in iron-deficient non-anaemic (IDNA) individuals remains controversial. Our objective is to identify the effects of iron therapy on fatigue and physical capacity in IDNA adults. DESIGN: Systematic review and meta-analysis of randomised controlled trials (RCTs). SETTING: Primary care. PARTICIPANTS: Adults (≥18 years) who were iron deficient but non-anaemic. INTERVENTIONS: Oral, intramuscular or intravenous iron supplementation; all therapy doses, frequencies and durations were included. COMPARATORS: Placebo or active therapy. RESULTS: We identified RCTs in Medline, Embase, Cochrane Central Register of Controlled Trials, Cumulative Index of Nursing and Allied Health, SportDiscus and CAB Abstracts from inception to 31 October 2016. We searched the WHO's International Clinical Trials Registry Platform for relevant ongoing trials and performed forward searches of included trials and relevant reviews in Web of Science. We assessed internal validity of included trials using the Cochrane Risk of Bias tool and the external validity using the Grading of Recommendations Assessment, Development and Evaluation methodology. From 11 580 citations, we included 18 unique trials and 2 companion papers enrolling 1170 patients. Using a Mantel-Haenszel random-effects model, iron supplementation was associated with reduced self-reported fatigue (standardised mean difference (SMD) -0.38; 95% CI -0.52 to -0.23; I2 0%; 4 trials; 714 participants) but was not associated with differences in objective measures of physical capacity, including maximal oxygen consumption (SMD 0.11; 95% CI -0.15 to 0.37; I2 0%; 9 trials; 235 participants) and timed methods of exercise testing. Iron supplementation significantly increased serum haemoglobin concentration (MD 4.01 g/L; 95% CI 1.22 to 6.81; I2 48%; 12 trials; 298 participants) and serum ferritin (MD 9.23 µmol/L; 95% CI 6.48 to 11.97; I2 58%; 14 trials; 616 participants). CONCLUSION: In IDNA adults, iron supplementation is associated with reduced subjective measures of fatigue but not with objective improvements in physical capacity. Given the global prevalence of both iron deficiency and fatigue, patients and practitioners could consider consumption of iron-rich foods or iron supplementation to improve symptoms of fatigue in the absence of documented anaemia.

Clinical Practice Guidelines for the Use of Video Capsule Endoscopy.

BACKGROUND & AIMS: Video capsule endoscopy (CE) provides a noninvasive option to assess the small intestine, but its use with respect to endoscopic procedures and cross-sectional imaging varies widely. The aim of this consensus was to provide guidance on the appropriate use of CE in clinical practice. METHODS: A systematic literature search identified studies on the use of CE in patients with Crohn's disease, celiac disease, gastrointestinal bleeding, and anemia. The quality of evidence and strength of recommendations were rated using the Grading of Recommendation Assessment, Development, and Evaluation (GRADE) approach. RESULTS: The consensus includes 21 statements focused on the use of small-bowel CE and colon capsule endoscopy. CE was recommended for patients with suspected, known, or relapsed Crohn's disease when ileocolonoscopy and imaging studies were negative if it was imperative to know whether active Crohn's disease was present in the small bowel. It was not recommended in patients with chronic abdominal pain or diarrhea, in whom there was no evidence of abnormal biomarkers typically associated with Crohn's disease. CE was recommended to assess patients with celiac disease who have unexplained symptoms despite appropriate treatment, but not to make the diagnosis. In patients with overt gastrointestinal bleeding, and negative findings on esophagogastroduodenoscopy and colonoscopy, CE should be performed as soon as possible. CE was recommended only in selected patients with unexplained, mild, chronic iron-deficiency anemia. CE was suggested for surveillance in patients with polyposis syndromes or other small-bowel cancers, who required small-bowel studies. Colon capsule endoscopy should not be substituted routinely for colonoscopy. Patients should be made aware of the potential risks of CE including a failed procedure, capsule retention, or a missed lesion. Finally, standardized criteria for training and reporting in CE should be defined. CONCLUSIONS: CE generally should be considered a complementary test in patients with gastrointestinal bleeding, Crohn's disease, or celiac disease, who have had negative or inconclusive endoscopic or imaging studies.

How can we improve models of care in inflammatory bowel disease? An international survey of IBD health professionals.

BACKGROUND AND AIMS: Few studies have specifically examined models of care in IBD. This survey was designed to help gather information from health professionals working in IBD services on current care models, and their views on how to best reshape existing models for IBD care worldwide. METHODS: An online mixed-methods survey was conducted with health professionals caring for IBD patients. Recruitment was conducted using the snowballing technique, where members of professional networks of the investigators were invited to participate. Results of the survey were summarised using descriptive statistics. RESULTS: Of the 135 included respondents, 76 (56%) were female, with a median age of 44 (range: 23-69) years, 50% were GI physicians, 34% nurses, 8% psychologists, 4% dieticians, 2% surgeons, 1% psychiatrists, and 1% physiotherapists. Overall, 73 (54%) respondents considered their IBD service to apply the integrated model of care, and only 5% reported that they worked exclusively using the biomedical care (no recognition of psychosocial factors). The majority of respondents reported including mental health assessment in their standard IBD care (65%), 51% believed that an ideal IBD service should be managed in specialist led clinics, and 64% wanted the service to be publicly funded. Respondents pictured an ideal IBD service as easy-access fully multi-disciplinary, with a significant role for IBD nurses and routine psychological and nutritional assessment and care. CONCLUSIONS: Health care professionals believe that an ideal IBD service should: be fully integrated, involve significant roles of nurses, psychologists and dieticians, run in specialist clinics, be easily accessible to patients and publicly funded.

Polymorphisms in the sodium-dependent ascorbate transporter gene SLC23A1 are associated with susceptibility to Crohn disease.

BACKGROUND: Crohn disease (CD) and ulcerative colitis (UC) are 2 common inflammatory bowel diseases (IBDs) associated with intestinal inflammation and tissue damage. Oxidative stress is suggested to play a major role in the initiation and progression of IBD. Vitamin C (ascorbate, ascorbic acid) supplementation has reduced oxidative stress in persons with IBD. The role of ascorbate transporters in IBD remains to be determined. SLC23A1 is a major ascorbate transporter in the intestinal tract, and some of its genetic variants have been associated with severely decreased ascorbate transport and lower systemic concentrations. OBJECTIVE: This study aimed to determine whether common genetic variants in the vitamin C transporter SLC23A1 are associated with the risk of IBD. DESIGN: Genomic DNA samples from patients with CD (n = 162) and UC (n = 149) from the Manitoba IBD Cohort Study and ethnically matched controls (n = 142) were genotyped for 3 SLC23A1 polymorphisms (rs6596473, rs33972313, and rs10063949) by using TaqMan assays. RESULTS: Variation at rs10063949 (G allele for heterozygote and homozygote) was associated with increased susceptibility to CD (OR: 2.54; 95% CI: 1.38, 4.66; OR: 4.72; 95% CI: 2.53, 8.81; P < 0.0001; respectively). A strong linkage disequilibrium (LD) was observed across the SLC23A1 region (variation rs6596473 with rs10063949) for CD and UC (D' = 0.94 and 0.96, respectively). The risk alleles confirmed a haplotype (CGG) that is carried more in CD patients (65.3%, P < 0.0001) than in controls (43.5%). CONCLUSIONS: A genetic variant (rs10063949-G) in the SLC23A1 ascorbate transporter locus was identified and is associated with an increased risk of CD in a white Canadian IBD cohort. The presented evidence that SLC23A1 variations can modulate the risk of CD has implications for understanding ascorbate transport in CD patients and provides a novel opportunity toward individualized nutritional therapy for patients carrying the disease-associated genotype.

Brain-gut interactions in inflammatory bowel disease.

Psycho-neuro-endocrine-immune modulation through the brain-gut axis likely has a key role in the pathogenesis of inflammatory bowel disease (IBD). The brain-gut axis involves interactions among the neural components, including (1) the autonomic nervous system, (2) the central nervous system, (3) the stress system (hypothalamic-pituitary-adrenal axis), (4) the (gastrointestinal) corticotropin-releasing factor system, and (5) the intestinal response (including the intestinal barrier, the luminal microbiota, and the intestinal immune response). Animal models suggest that the cholinergic anti-inflammatory pathway through an anti-tumor necrosis factor effect of the efferent vagus nerve could be a therapeutic target in IBD through a pharmacologic, nutritional, or neurostimulation approach. In addition, the psychophysiological vulnerability of patients with IBD, secondary to the potential presence of any mood disorders, distress, increased perceived stress, or maladaptive coping strategies, underscores the psychological needs of patients with IBD. Clinicians need to address these issues with patients because there is emerging evidence that stress or other negative psychological attributes may have an effect on the disease course. Future research may include exploration of markers of brain-gut interactions, including serum/salivary cortisol (as a marker of the hypothalamic-pituitary-adrenal axis), heart rate variability (as a marker of the sympathovagal balance), or brain imaging studies. The widespread use and potential impact of complementary and alternative medicine and the positive response to placebo (in clinical trials) is further evidence that exploring other psycho-interventions may be important therapeutic adjuncts to the conventional therapeutic approach in IBD.

Integrated models of care in managing inflammatory bowel disease: a discussion.

The World Health Organization has recommended the integrated model of care as the current best practice of care, and, in recent years, it has been gaining popularity worldwide in various settings. However, there have been very few reports on applications of this model to the care of patients with gastrointestinal problems and no reports in the case of inflammatory bowel disease (IBD). However, several IBD centres worldwide have been using the model as part of their standard care. This discussion paper aims to bring together these units' shared experiences with a range of integrated models of care in order to identify common features and provide recommendations on aspirational care for IBD patients.

Homocysteinemia and B vitamin status among adult patients with inflammatory bowel disease: a one-year prospective follow-up study.

BACKGROUND: The aim of this study was to longitudinally study serum homocysteine levels in patients with Crohn's disease (CD) and ulcerative colitis (UC) in relation to disease activity and B vitamin status. METHODS: In all, 98 consecutive adult patients (age 25-55 years) with CD (n = 70) and UC (n = 28) were enrolled and assessed at three timepoints over 1 year. RESULTS: There were no significant differences in levels of homocysteine, B vitamins, or dietary intake by disease type, disease activity, or across visits. 13% of all inflammatory bowel disease (IBD) patients had elevated homocysteine at least once during the study. Nine patients with CD had fluctuating homocysteine levels during the study but these were inconsistent, ranging from within normal range to elevated levels in any individual. Six of these nine patients were persistently in remission. 30% of all IBD patients had vitamin B6 deficiency, 11% had vitamin B12 deficiency, and one patient (CD) had folate deficiency. All vitamins showed a significant correlation between intake and serum levels (B6; r = 0.46, P < 0.001, B12; r = 0.42, P < 0.001, and folate; r = 0.26, P = 0.008). There was an inverse relationship between serum homocysteine in the blood and serum vitamin B12 (r = -0.241, P = 0.017). CONCLUSIONS: Serum homocysteine was mostly normal in patients with IBD and changed minimally over time. There was no association between disease activity and elevation of serum homocysteine. 30% of patients have vitamin B6 deficiency but vitamin B6 is not associated with elevated homocysteine. The routine measurement of homocysteine is not warranted.

Role of biological therapy for inflammatory bowel disease in developing countries.

Inflammatory bowel disease (IBD) has become a global disease. Its incidence in developing countries is rising. In Asia, this has been attributed to the rapid modernisation and westernisation of the population. As IBD emerges in developing nations, there is a need to reconcile the most appropriate treatment for these patient populations from the perspectives of both disease presentation and cost. In the West, biological agents are the fastest-growing segment of the prescription drug market. They typically cost several thousand to several tens of thousands of dollars per patient per year. The healthcare systems in developing countries will struggle to afford such expensive treatments. Developing countries cover two-thirds of the earth's surface and are home to 3-5 billion inhabitants, constituting three-quarters of all humanity. If IBD emerges to the same extent in those countries as it has in the West, the need for biological therapy will increase dramatically, and the pharmaceutical industry, healthcare providers, patient advocate groups, governments and non-governmental organisations will have to discuss how to handle this. The authors propose that this dialogue should begin now with regard to (1) the major needs of patients with complicated IBD in developing countries, (2) the potential need for biological therapy in developing countries to treat IBD, (3) the necessary infrastructure for selecting patients with IBD who need biological therapy, and (4) medical/ethical issues limiting the use of biological therapy.

The Manitoba Inflammatory Bowel Disease Cohort Study: a prospective longitudinal evaluation of the use of complementary and alternative medicine services and products.

OBJECTIVE: To determine the prevalence of complementary and alternative medicine (CAM) use over time in a population-based cohort of patients with inflammatory bowel disease (IBD). METHODS: The Manitoba IBD Cohort Study is a longitudinal, population-based study of multiple determinants of health outcomes in an IBD cohort. Participants completed semi-annual surveys, and annual in-person interviews. Enquiries about the use of 12 types of CAM service providers and 13 CAM products, based on items from a national survey, were included at months 0, 12, 30 and 54. RESULTS: Overall, 74% of respondents used a CAM service or product in the 4.5-year period, with approximately 40% using some type of CAM at each time point, and 14% using CAM consistently at every time point. There was a trend for women to use CAM more than men; there was no difference in CAM use between patients with Crohn's disease and those with ulcerative colitis. The most often used CAM services (on average) were massage therapy (30%) and chiropractic (14%), physiotherapy (4%), acupuncture (3.5%) and naturopathy/homeopathy (3.5%). A wide range of CAM products were used, with Lactobacillus acidophilus (8%), fish and other oils (5.5%), glucosamine (4%) and chamomile (3.5%) as the most common. On average, only 18% of consumers used CAM for their IBD, so the majority chose it for other problems. There were no differences in psychological variables between CAM users and non-users. CONCLUSIONS: Those with IBD commonly try CAM, although very few use these approaches regularly over the years. CAM is not usually used by patients with IBD for disease management, but clinicians should be aware that many will test the services and products.

Ciprofloxacin or metronidazole for the treatment of perianal fistulas in patients with Crohn's disease: a randomized, double-blind, placebo-controlled pilot study.

BACKGROUND: Although metronidazole and ciprofloxacin are used to treat perianal Crohn's disease (CD), no placebo-controlled trials have been performed. METHODS: We performed a placebo-controlled pilot trial to evaluate the efficacy and safety of metronidazole and ciprofloxacin in patients with perianal CD. Twenty-five patients with CD and actively draining perianal fistulas were randomized to receive ciprofloxacin 500 mg, metronidazole 500 mg, or placebo twice daily for 10 weeks. Remission and response of perianal fistulas were defined as closure of all fistulas and closure of at least 50% of fistulas that were draining at baseline, respectively. The primary endpoint was remission at 10 weeks. RESULTS: Ten patients were randomized to ciprofloxacin, 7 to metronidazole, and 8 to placebo. Remission at week 10 occurred in 3 patients (30%) treated with ciprofloxacin, no patients (0%) treated with metronidazole, and 1 patient (12.5%) treated with placebo (P = 0.41). Response at week 10 occurred in 4 patients (40%) treated with ciprofloxacin, 1 patient (14.3%) treated with metronidazole, and 1 patient (12.5%) treated with placebo (P = 0.43). Termination of the trial prior to week 10 occurred in 1 patient (10%) treated with ciprofloxacin, 5 patients (71.4%) treated with metronidazole, and 1 patient (12.5%) treated with placebo (P < 0.02). No serious adverse events occurred. CONCLUSION: Remission and response occurred more frequently in patients treated with ciprofloxacin but the differences were not significant in this pilot study. Ciprofloxacin was well tolerated.

Drug therapy for inflammatory bowel disease in pregnancy and the puerperium.

Inflammatory bowel disease (IBD) has a peak age of onset in the 3rd decade and a peak prevalent age in the fourth decade in most studies. As a result many patients affected by Crohn's disease and ulcerative colitis are females of reproductive age interested in bearing children. It has been shown that the most important factor in the success of a pregnancy in patients with IBD is the state of disease activity. Therefore, the goal prior to and during pregnancy is to best optimise control of the disease through medical therapy. Unfortunately, many medications utilised to treat IBD are potentially toxic and/or teratogenic, leaving many physicians and patients without a clear answer as to the safest methods of therapy. This review attempts to summarise the medical literature to date, as it pertains to the safety of medical therapy for IBD during pregnancy and the puerperium.
