Urinary tract infections in hospitalized inflammatory bowel disease patients: a 10-year experience

Exploring Factors Affecting Acceptance of Fecal Microbiota Transplantation for Patients with Recurrent Urinary Tract Infections: a Descriptive Qualitative Study

Purpose

Patients with recurrent urinary tract infections face complex management challenges. Fecal microbiota transplantation is a superior treatment for chronic infectious diseases, but limited patient knowledge affects treatment decisions. This study aims to identify factors associated with hesitancy towards fecal microbiota transplantation among patients with recurrent urinary tract infections, to help physicians and nurses in providing accurate and useful information to patients.

Patients and Methods

A descriptive qualitative approach was employed, utilizing semi-structured interviews conducted with patients experiencing recurrent urinary tract infections who expressed hesitancy towards fecal microbiota transplantation. The interviews took place between September 2021 and December 2022. Thematic analysis was conducted on the semi-structured interviews to identify perceived facilitators and barriers associated with fecal microbiota transplantation.

Results

The analysis included interviews with thirty adult female patients with recurrent urinary tract infections. Four facilitators influencing patients' decision-making regarding fecal microbiota transplantation were identified: (1) the motivating role of hope and expectations for active patient participation; (2) the influence of healthcare providers, as well as family members and friends on patients' decisions to pursue fecal microbiota transplantation; (3) the patients' perception of fecal microbiota transplantation as a low-risk treatment option; and (4) the dedication to the advancement of medical treatments. In contrast, two primary barriers to accepting fecal microbiota transplantation were identified: (1) that conventional treatment controls disease activity, while fecal microbiota transplantation effects remain uncertain; and (2) that safety concerns surrounding fecal microbiota transplantation.

Conclusion

Comprehensive information about fecal microbiota transplantation, including donor selection, sample processing, the procedure, and potential discomfort, is essential for patients and families to make informed treatment decisions.

Phylogrouping and characterization of Escherichia coli isolated from colonic biopsies and fecal samples of patients with flare of inflammatory bowel disease in Iran

Background

Although the etiopathogenesis of inflammatory bowel disease (IBD) is still poorly understood, Escherichia coli has been described as a potential causative microorganism in IBD pathogenesis and also disease progression, offering a potential therapeutic target for disease management. Therefore, we conducted this study to investigate the pathotypes, phylogenetic groups, and antimicrobial resistance of E. coli isolates from patients with IBD in Iran.

Methods

Fecal and biopsy colonic samples were collected from IBD patients experiencing flare-up episodes referred to Taleghani hospital in Tehran, Iran, between August 2020 and January 2021. Identification of E. coli strains was performed based on biochemical and molecular methods. Antibiotic susceptibility testing was performed as recommended by the Clinical and Laboratory Standards Institute. Phylogrouping and pathotyping of each isolate were carried out using polymerase chain reaction (PCR) and multilocus sequence typing (MLST) assays.

Results

A total of 132 non-duplicate E. coli strains were isolated from 113 IBD patients, including 96 ulcerative colitis (UC), and 17 Crohn’s disease (CD) patients. In our study, 55% of CD-related E. coli and 70.5% of UC-related isolates were non-susceptible to at least three or more unique antimicrobial classes, and were considered as multidrug-resistant (MDR) strains. E. coli strains exhibited a high level of resistance to cefazolin, ampicillin, tetracycline, ceftazidime, ciprofloxacin, and cefotaxime. Enterotoxigenic E. coli (ETEC) and diffusely adherent E. coli (DAEC) were the most prevalent pathotypes, and groups B2 and D were the predominant phylogroups.

Conclusion

In the present study, we found that E. coli strains that colonize the gut of Iranian patients with IBD most frequently belonged to phylogenetic groups B2 and D. We also conclude that E. coli isolates from IBD patients have been revealed to be resistant to commonly used antibiotics, in which most of them harbored strains that would be categorized as MDR.

Adverse Clinical Outcomes among Inflammatory Bowel Disease Patients Treated for Urinary Tract Infection

Background: Urinary tract infection (UTI) is the most common urologic complication among patients with inflammatory bowel disease (IBD). However, data regarding UTI outcomes in this population are scarce. We aimed to evaluate adverse outcomes of UTI among patients with IBD. Methods: This was a retrospective cohort study of consecutive adult patients who visited the emergency room (ER) at Sheba Medical Center due to a UTI between 2012 and 2018. Data included demographic and clinical variables. UTI cases were extracted using ICD-10 coding. Results: Of 21,808 (ER) visits with a UTI, 122 were IBD patients (Crohn’s disease—52, ulcerative colitis—70). Contrary to non-IBD subjects, patients with IBD had higher rates of hospitalization, acute kidney injury (AKI) and 30 day-recurrent hospitalization (59.3% vs. 68.9%, p = 0.032; 4.6% vs. 13.9%, p < 0.001; 7.3% vs. 15.6%, p = 0.001, respectively). Among patients with IBD, advanced age (p = 0.005) and recent hospitalization (p = 0.037) were associated with increased risk for hospitalization, while hydronephrosis (p = 0.005), recent hospitalization (p = 0.011) and AKI (p = 0.017) were associated with increased 30-day recurrent hospitalization. Neither immunosuppressants nor biologics were associated with UTI outcomes among patients with IBD. Conclusions: Patients with IBD treated for a UTI had higher rates of hospitalization, AKI and 30-day recurrent hospitalization than non-IBD patients. No association was observed between immunosuppressants or biologics and UTI outcomes.

Urinary manifestations in African American and Caucasian inflammatory bowel disease patients: a retrospective cohort study

Background

Inflammatory bowel diseases (IBD), like ulcerative colitis (UC) and Crohn’s disease (CD), are associated with urinary extra-intestinal manifestations, like urolithiasis and uncomplicated urinary tract infections (UTIs). The literature reviewed for this study identifies an increased association of CD and urolithiasis against the general population as well as UC. Furthermore, the rates in which urinary comorbidities manifest have not been well characterized in cross-race analyses. The purpose of this study is to establish the prevalence of common urinary extra-intestinal manifestations in CD and UC and to further determine at what rate these affect the African American and Caucasian populations.

Methodology

This is a retrospective cohort study using de-identified data collected from a research data base that included 6 integrated facilities associated with one tertiary healthcare center from 2012 to 2019. The electronic chart records for 3104 Caucasian and African American IBD patients were reviewed for frequency of urolithiasis and uncomplicated UTI via diagnosed ICD-10 codes. Comparison between data groups was made using multivariate regressions, t-tests, and chi square tests.

Results

Our study included 3104 patients of which 59% were female, 38% were African American, and 43% were diagnosed with UC. Similar proportions of UC and CD diagnosed patients developed urolithiasis (6.0% vs 6.7%, p = 0.46), as well as uncomplicated UTIs (15.6% vs. 14.9%, p = 0.56). Similar proportions of African American and Caucasian patients developed urolithiasis (5.4% vs 7.0%, p = 0.09), but a higher proportion of African Americans developed uncomplicated UTIs (19.4% vs 12.6%, p ≤ 0.001).

Conclusion

We found similar rates of urolithiasis formation in both UC and CD in this study. Furthermore, these rates were not significantly different between African American and Caucasian IBD populations. This suggests that UC patients have an elevated risk of urolithiasis formation as those patients with CD. Additionally, African Americans with IBD have a higher frequency of uncomplicated UTI as compared to their Caucasian counterparts.

Treatment Persistence of Infliximab Versus Adalimumab in Ulcerative Colitis: A 16-Year Single-Center Experience

BACKGROUND

Infliximab and adalimumab are widely used in the treatment of patients with ulcerative colitis (UC). There are few published data on the treatment persistence of infliximab and adalimumab in patients with UC.

METHODS

We aimed to compare the treatment persistence rates of infliximab versus adalimumab as first- and second-line tumor necrosis factor antagonists (anti-TNF), to identify factors potentially associated with persistence, and to evaluate reasons for withdrawal in UC patients. We performed a retrospective, single-center cohort study of UC patients treated with infliximab or adalimumab for at least 6 months between June 2002 and May 2018.

RESULTS

The median (interquartile range [IQR]) duration of follow-up was 5.4 (3.2-8.3) years. For first-line anti-TNF agent, data on 160 patients with UC were analyzed. The mean (SD) duration of persistence was 3.4 (3.5) years and 2.1 (2.0) years in the infliximab and adalimumab subgroups, respectively (P = 0.24). Concomitant use of 5-aminosalicylate was associated with higher persistence of first-line anti-TNF treatment in the overall population (hazard ratio [HR] 0.5; 95% CI, 0.3-0.8; P = 0.002). For second-line anti-TNF agent, data on 43 patients were analyzed. The mean (SD) duration of persistence was 2.0 (1.7) years and 3.2 (3.1) years in the infliximab and adalimumab subgroups, respectively (P = 0.95). No factors were associated with persistence of second-line anti-TNF treatment.

CONCLUSIONS

Infliximab and adalimumab showed similar levels of persistence as first- and second-line anti-TNF treatments. Concomitant use of 5-aminosalicylates was associated with higher persistence of first-line anti-TNF treatment.

Value of cross-sectional imaging in assessing active Crohn's disease before stoma reversal

BACKGROUND

There are currently no guidelines on the need to assess disease activity before stoma reversal in Crohn's disease (CD). We sought to determine the value of cross-sectional imaging for detecting active CD before stoma reversal.

METHODS

38 CD patients underwent cross-sectional imaging before stoma reversal. CD activity was blindly evaluated by an independent radiologist. Postoperative outcomes were recorded.

RESULTS

Before stoma reversal, cross-sectional imaging identified active CD in 20 of the 38 study participants (52.6%). In 9 out of 10 tested patients, radiologic and endoscopic assessments gave concordant findings with regard to CD recurrence before stoma reversal. Stoma reversal was delayed in half of the patients with active CD and in none of the patients without active CD. Before stoma reversal, tumor necrosis factor alpha antagonists or immunosuppressants were initiated in 45% of the patients with active CD and 5.6% of the patients without active CD. In the year following stoma reversal, the recurrence rate (in a radiologic assessment) was higher in patients with active CD than in patients without active CD (75.0% vs. 30.8%, respectively; p=0.04).

CONCLUSION

Cross-sectional imaging revealed postoperative recurrence in about a quarter of patients before stoma reversal; this finding may influence the postoperative treatment strategy and outcomes.

Treatment Persistence for Infliximab Versus Adalimumab in Crohn's Disease: A 14-Year Single-Center Experience

BACKGROUND

Infliximab (IFX) and adalimumab (ADA) are widely used in the treatment of patients with Crohn's disease (CD). There are few published data on the treatment persistence of IFX and ADA in patients with CD.

METHODS

We aimed to compare the persistence rates of IFX versus ADA as first- and second-line tumor necrosis factor antagonist (anti-TNF), to identify factors potentially associated with persistence, and to evaluate reasons for treatment withdrawal in CD patients. We performed a retrospective, single-center cohort study of CD patients treated with IFX or ADA for at least 6 months between June 2002 and May 2016.

RESULTS

The median duration of follow-up was 5.4 years. For first-line anti-TNF agent, data on 487 patients with CD were analyzed. The mean (SD) duration of persistence was 3.6 (3.1) years and 2.5 (2.0) years in the IFX and ADA subgroups, respectively; the intergroup difference was not significant (P = 0.219). Factors associated with lower persistence were female sex (P = 0.0005) and stricturing behavior (P = 0.008). For second-line anti-TNF agent, data on 134 patients were analyzed. The mean (SD) duration of persistence was 2.4 (1.9) years and 2.6 (2.1) years in the IFX and ADA subgroups, respectively; again, the intergroup difference was not significant (P = 0.488). Age under 37.2 was the only factor associated with lower persistence (P = 0.016) for second-line treatment with an anti-TNF agent.

CONCLUSIONS

IFX and ADA show similar levels of persistence as first- and second-line anti-TNF treatments. Female sex and stricturing behavior were associated with poor persistence of first-line treatments, whereas age was the only factor associated with poor persistence of second-line treatments.

Accuracy of Diffusion-weighted Magnetic Resonance Colonography in Assessing Mucosal Healing and the Treatment Response in Patients with Ulcerative Colitis

BACKGROUND AND AIMS

Using sigmoidoscopy as the gold standard, we assessed the accuracy, and the responsiveness to change, of diffusion-weighted magnetic resonance colonography in ulcerative colitis, using the Nancy score.

METHODS

A total of 29 ulcerative colitis patients, having undergone at least two diffusion-weighted magnetic resonance colonographies, were included. Disease activity was evaluated using the Mayo endoscopic subscore and the Nancy score. We determined the accuracy of the Nancy score in the diagnosis of mucosal healing. We also assessed its responsiveness to change in 17 patients with a Mayo endoscopic subscore of 2 or 3 at treatment initiation.

RESULTS

A total Nancy score < 7 had a sensitivity of 0.75 and a specificity of 0.67 (area under the curve: 0.72; 95% confidence interval: [0.56-0.88]; p = 0.0063) in the diagnosis of mucosal healing. The total Nancy score was sensitive to change in ulcerative colitis [Guyatt's responsiveness index: 1.8; standardised effect size ratio: 1.36]. The Nancy score was reliable [intra-class correlation coefficient: 0.63; p = 0.01]. The mean Mayo endoscopic subscore and the mean Nancy score both fell significantly in patients who achieved mucosal healing (mean ± standard deviation [SD] Mayo endoscopic subscore: 2.4 ± 0.55 at baseline and 0.6 ± 0.55 at reassessment, p = 0.02; mean Nancy score: 18.2 ± 9.1 at baseline and 3 ± 1.6 at reassessment, p = 0.006). No significant changes in Nancy score were observed in active patients at reassessment.

CONCLUSIONS

The Nancy score is a highly responsive, reliable tool for assessing treatment response in patients with ulcerative colitis. The Nancy score accurately detects mucosal healing.

Genetic risk factors for serious infections in inflammatory bowel diseases

INTRODUCTION

Immunosuppression, the cornerstone of management of Crohn's disease (CD) and ulcerative colitis (UC) (inflammatory bowel diseases; IBD) is associated with an increased risk of serious infections that is inadequately predicted by clinical risk factors. The role of genetics in determining susceptibility to infections is unknown.

METHODS

From a prospective-consented patient registry, we identified IBD patients with serious infections requiring hospitalization. Analysis was performed to identify IBD-related and non-IBD related immune response loci on the Immunochip that were associated with serious infections and a genetic risk score (GRS) representing the cumulative burden of the identified single nucleotide polymorphisms was calculated. Multivariable logistic regression used to identify effect of clinical and genetic factors.

RESULTS

The study included 1333 IBD patients (795 CD, 538 UC) with median disease duration of 13 years. A total of 133 patients (10%) had a serious infection requiring hospitalization. Patients with infections were more likely to have CD and had shorter disease duration. The most common infections were skin and soft-tissue, respiratory and urinary tract infections. Eight IBD risk loci and two other polymorphisms were significantly associations with serious infections. Each one point increase in the infection GRS was associated with a 50% increase in risk of infections (OR = 1.53, 95% CI = 1.37-1.70) (p = 1 × 10^-14), confirmed on multivariable analysis. Genetic risk factors improved performance of a model predicting infections over clinical covariates alone (p < 0.001).

CONCLUSIONS

Genetic risk factors may predict susceptibility to infections in patients with IBD.

Impact of immunosuppressive therapy on hepatitis B vaccination in inflammatory bowel diseases

BACKGROUND AND AIMS

The vaccination rate against hepatitis B virus (HBV) is low in inflammatory bowel disease (IBD) patients. The Consensus from the European Crohn's and Colitis Organisation on opportunistic infections recommends testing all IBD patients for HBV at diagnosis and vaccinating all HBV-negative patients. We compared the efficacy of HBV vaccine between IBD patients and healthy controls and investigated the impact of immunosuppressive therapy on vaccine response in IBD patients.

MATERIALS AND METHODS

IBD patients and healthy adult workers were vaccinated against HBV following a standard protocol (at 0, 1, and 6 months; Engerix B). The efficacy of vaccination was evaluated at 8 months by a titer of antibodies against hepatitis B surface antigen (anti-HBs).

RESULTS

Among 164 participants (96 with IBD and 68 healthy workers), the level of anti-HBs was greater than 10 IU/l in 80.2 and 94.1% (P=0.0115) of IBD patients and healthy controls, respectively, and anti-HBs levels greater than 100 IU/l were seen in 45.8 versus 77.9% (P<0.0001) of IBD patients and healthy controls, respectively. The median level of anti-HBs was significantly higher in healthy controls (497.0±386.2) than in IBD patients (253.9±34.5) (P<0.0001). None of the baseline characteristics of IBD patients, including immunomodulators and antitumor necrosis factor therapy, influenced the vaccine response. In the multivariate analysis, ileal disease was the only factor associated with a lower response to the vaccine (odds ratio=3.2; 95% confidence interval=1.0-9.7; P=0.049).

CONCLUSION

The response rate to HBV vaccination is significantly lower in IBD patients than in the general population. Immunosuppressive therapy for IBD did not influence the vaccine response.

Beliefs and behaviour about smoking among inflammatory bowel disease patients

BACKGROUND AND AIMS

We investigated the beliefs and behaviours about tobacco among inflammatory bowel disease (IBD) patients.

MATERIALS AND METHODS

A questionnaire of 18 items was developed and administered to all consecutive patients followed for IBD at Nancy University Hospital from October 2012 to March 2013.

RESULTS

Two hundred and thirty-one patients participated in the survey [Crohn's disease (CD)=171, ulcerative colitis (UC)=60]. Among IBD patients who were smokers at diagnosis, 10.5% of CD patients versus 14.3% of UC patients believed that tobacco could have triggered their IBD; about half the CD smokers at diagnosis were not aware that smoking might promote their disease. Three quarters of smokers after diagnosis knew that tobacco was not beneficial for their CD, whereas all UC were aware that smoking had a beneficial effect on their disease course. About half of the CD patients had stopped smoking during a flare-up. Four former smokers with UC (21.1%) resumed smoking during a relapse. Nearly 90% of IBD current smokers wished to quit smoking. About half the IBD patients were aware of the relation between smoking and IBD, and the Internet was a source for 24.3% of these patients.

CONCLUSION

The majority of IBD patients are unaware of the effects of tobacco on their disease. Better information through a therapeutic education programme should be systematically recommended in IBD.

Urolithiasis and urinary tract infection among patients with inflammatory bowel disease: a review of US emergency department visits between 2006 and 2009

OBJECTIVE

To compare patients with inflammatory bowel disease (IBD) to a general population of urinary stone formers who present to US emergency departments with infected urolithiasis. Patients with IBD are at risk for both infection and stone formation, however studies investigating emergent urolithiasis presentations for this population are limited.

METHODS

Using the Nationwide Emergency Department Sample (2006-2009) we identified all patients presenting to the US emergency departments with a diagnosis of upper tract urolithiasis. We then described a subgroup with the concomitant diagnosis of IBD. We compared rates of urinary tract infection (UTI), sepsis, organ failure, admission, and mortality between the 2 groups. Using multivariate analysis, we determined whether or not IBD was a predictor of UTI, sepsis, and hospitalization.

RESULTS

Overall, 14,352 patients had concomitant IBD and urolithiasis. IBD patients with urolithiasis presented with infections (10.4% vs 9.1%; P <.001), sepsis (0.6% vs 0.2%; P <.001), and end-organ failure (6.3% vs 1.6%; P <.001) more frequently than non-IBD patients. They were also more likely to have characteristics independently associated with infection and sepsis, such as older age and female gender. In adjusted analyses, IBD was an independent predictor of infection (odds ratio [OR] = 1.3 [1.14-1.46]; P <.0001), sepsis (OR = 1.8 [1.09-2.92]; P <.0001), and admission (OR = 3.3 [3.04-3.64]; P <.0001).

CONCLUSION

IBD patients with urinary calculi have greater odds of UTI, renal failure, and sepsis compared to the general stone-forming population. The increased occurrence and severity of infected urolithiasis in this select group of patients warrants screening for stone disease, improved outpatient medical management, and early elective surgery for detected stones.

Tolerability of one hour 10mg/kg infliximab infusions in inflammatory bowel diseases: a prospective multicenter cohort study

BACKGROUND AND AIM

In patients with inflammatory bowel disease (IBD) tolerating 2-h infusions of 5mg/kg infliximab scheduled maintenance therapy, the infusion time can be shortened to 1-h with good tolerability. A retrospective study with small sample size demonstrated the feasibility of 1-hour infusion time for 10mg/kg infliximab in IBD patients.

METHODS

Between November 2011 and July 2012, 63 patients received 1-hour 10mg/kg infliximab infusions under standard operating procedures and were enrolled in a prospective observational study. Intravenous steroid premedication was given to all patients.

RESULTS

Sixty-three IBD patients on infliximab maintenance therapy (43 Crohn's disease, 34 males) received 1-hour 10mg/kg infusions during the study period. A total of 182 infliximab infusions were administered. Seventeen (26%) patients were receiving concomitant immunomodulators. Two patients experienced (2/182, 1%) severe acute infusion reactions consisting on a cutaneous lupus and one severe anaphylactic reaction. We also observed one (1/182, 0.5%) severe delayed reaction after the first 1-hour infliximab infusion consisting on acne generalis. All 3 reactions led to infliximab discontinuation. No mild acute reactions and 6 mild delayed reactions (6/182, 3%) occurred.

CONCLUSIONS

In patients with IBD receiving infliximab scheduled maintenance therapy, 1-hour infusion time for 10mg/kg infliximab seems to be well tolerated. This option might be considered in clinical practice in order to decrease the extra-burden of infliximab infusions in this patient population.

The extra burden of infliximab infusions in inflammatory bowel disease

BACKGROUND

Infliximab (IFX) infusions require repeated hospitalizations. The median duration of each hospitalization stay, including time for infusion and the cost for the health care system, are unknown. We assessed the extra burden of IFX infusions in inflammatory bowel disease (IBD).

METHODS

This was a prospective cross-sectional study enrolling all consecutive patients with IBD treated with IFX at the Nancy IBD Unit (January to March 2012). Four parameters were assessed: median travel duration, median time that patients stayed at the IBD unit, reimbursement for transport by the health care system, and impact of IFX infusions on their work.

RESULTS

Among 137 IBD patients, 48.9% were women, 74.5% had Crohn's disease, and the median age was 35 (range, 18-65) years. The median travel duration backward and forward from home to the Nancy IBD unit was 2 (range, 0.5-4) hours. The patients stayed at the IBD unit for a median period of 4.5 (range, 2.8-6.7) hours. For 63.5% of the patients (87/137), transport was reimbursed by the health care system. Of the patients receiving IFX infusions, 10.9% (15/137) were unemployed, 24.8% (34/137) had the agreement of their employer to spend 1 day at the hospital for their IFX infusion, 27.0% (36/137) asked specifically a vacation for the IFX infusion, and 13.9% (19/137) were in sick leave.

CONCLUSIONS

The patients spend a median of 6.5 hours outside their home for each IFX infusion, and they often take a day of vacation or rest. This represents an extra burden for IFX-treated patients and for the health care system.

Metabolomic profiles are gender, disease and time specific in the interleukin-10 gene-deficient mouse model of inflammatory bowel disease

Metabolomic profiling can be used to study disease-induced changes in inflammatory bowel diseases (IBD). The aim of this study was to investigate the difference in the metabolomic profile of males and females as they developed IBD. Using the IL-10 gene-deficient mouse model of IBD and wild-type mice, urine at age 4, 6, 8, 12, 16, and 20 weeks was collected and analyzed by nuclear magnetic resonance (NMR) spectroscopy. Multivariate data analysis was employed to assess differences in metabolomic profiles that occurred as a consequence of IBD development and severity (at week 20). These changes were contrasted to those that occurred as a consequence of gender. Our results demonstrate that both IL-10 gene-deficient and wild-type mice exhibit gender-related changes in urinary metabolomic profile over time. Some male-female separating metabolites are common to both IL-10 gene-deficient and control wild-type mice and, therefore, appear to be related predominantly to gender maturation. In addition, we were able to identify gender-separating metabolites that are unique for IL-10 gene-deficient and wild-type mice and, therefore, may be indicative of a gender-specific involvement in the development and severity of the intestinal inflammation. The comparison of the gender-separating metabolomic profile from IL-10 gene-deficient mice and wild-type mice during the development of IBD allowed us to identify changes in profile patterns that appear to be imperative in the development of intestinal inflammation, but yet central to gender-related differences in IBD development. The knowledge of metabolomic profile differences by gender and by disease severity has potential clinical implications in the design of both biomarkers of disease as well as the development of optimal therapies.

Colonoscopic perforations in inflammatory bowel disease: a retrospective study in a French referral centre

BACKGROUND

Whether inflammatory bowel disease patients are at increased risk of colonoscopic perforations remains controversial. Aim of this study was to investigate whether these patients are at increased risk of perforations.

METHODS

Electronic charts of all patients enrolled in the Nancy IBD cohort (1999-2012) were reviewed. All non-inflammatory bowel disease patients who underwent colonoscopy (1999-2012) were used as controls.

RESULTS

Of 17,992 colonoscopies, 2375 (13.2%) were performed for inflammatory bowel disease: 1547 for Crohn's disease and 828 for ulcerative colitis. Four IBD patients (0.168%) experienced perforation. Perforation occurred in the sigmoid colon (n = 3) and right colon (n = 1) during disease monitoring or colonic stenosis dilatation. Three patients underwent surgery (2 stomas and no death). Colonoscopic perforation occurred in 16/15,617 controls (0.102%): colonic cancer diagnosis (n = 5, 31.3%) or dilatation (n = 2, 12.5%), polypectomy (n = 5, 31.3%) or mucosectomy (n = 1, 6.3%), and follow-up after diverticulitis (n = 2, 12.5%). Perforation rate was not different between IBD and controls (p = 0.57). Perforations occurred in the sigmoid colon (n = 10, 62.5%), the right colon (n = 4, 25%) and the rectum (n = 2, 12.5%). Twelve controls underwent surgery (9 stomas and one death).

CONCLUSION

In this referral centre-based cohort, inflammatory bowel disease patients were not at increased risk of colonoscopic perforation compared to non-IBD controls.

Ocular symptoms are not predictive of ophthalmologic inflammation in inflammatory bowel disease

BACKGROUND

Ocular manifestations are frequent in patients with inflammatory bowel disease.

AIM

To evaluate for the first time the value of ocular symptoms in predicting ophthalmologic inflammation in inflammatory bowel disease.

METHODS

All consecutive inflammatory bowel disease patients seen in the Department of Gastroenterology (Nancy, University Hospital, France) between April 2009 and July 2011 were interviewed for this cross-sectional study using a pre-established questionnaire. If the patient had at least one ocular symptom, he systematically underwent an ophthalmologic examination (visual acuity, Break-Up Time test, Schirmer Test, slit-lamp exam with fundus examination).

RESULTS

This cross-sectional survey was completed by 305 patients: 169 were women (55.2%), 228 had Crohn's disease (74.5%). Ninety-eight patients (32%) reported at least one ocular symptom: ocular irritation (56.8%), red eye (40.5%), blurred vision (37.8%), progressive visual loss (34.4%), ocular pain (31.1%), myodesopsia (23.3%), eyelid secretion (12.2%), dry eye (9.5%), watering (6.8%), diplopia (5.4%), metamorphopsia (4%), and sudden visual loss (4%). Following ophthalmologic examination (n=74), 41.9% patients had evidence of dry eye (n=31), 14.9% blepharitis (n=11) and 1.4% scleritis (n=1). No uveitis was reported.

CONCLUSION

Ocular symptoms are frequent in inflammatory bowel disease, but are non-specific and rarely associated with ocular inflammation. Systematic ocular symptoms assessment is of poor value for diagnosing ocular inflammation in inflammatory bowel disease.

Methotrexate for psoriasiform lesions associated with anti-tumour necrosis factor therapy in inflammatory bowel disease

BACKGROUND

Psoriasiform lesions associated with anti-tumour necrosis factor (TNF) therapy are frequent in patients with inflammatory bowel disease (IBD). While methotrexate is the most frequently used systemic treatment for psoriasis, its efficacy for psoriasiform lesions related to anti-TNF therapy remains unknown.

AIMS

To assess the efficacy of methotrexate for psoriasiform lesions associated with anti-TNF therapy refractory to topical therapy in IBD patients.

METHODS

The charts of eight patients from the Nancy IBD cohort who developed psoriasiform lesions on anti-TNF therapy were reviewed. Clinical response was defined as a decrease of more than 50% in the lesions covering surface. All patients were followed up by the same experienced dermatologist.

RESULTS

Eight women (seven Crohn's disease) were followed up for a median duration of 29 months (range, 20-45). Of the eight patients receiving methotrexate, three were primary responders without discontinuation of anti-TNF agents. Only one patient had a sustained response at final follow-up and was able to continue both methotrexate and anti-TNF therapy. Of the two other primary responders, one patient had to discontinue anti-TNF because of severe psoriasiform lesions, whereas the other one continued anti-TNF therapy despite persistent skin lesions at final follow-up. Among the five primary nonresponders, four patients had to stop anti-TNF treatment due to disabling skin lesions.

CONCLUSION

Methotrexate does not appear effective in treating psoriasiform lesions associated with anti-TNF therapy refractory to topical therapy in IBD.
