Quality of Life in Inflammatory Bowel Disease: A Systematic Review and Meta-analyses-Part I

Associations between disease activity, social support and health-related quality of life in patients with inflammatory bowel diseases: the mediating role of psychological symptoms

Background

Previous studies have indicated that disease activity, psychological symptoms and social support were associated with health-related quality of life (HRQoL) in patients with inflammatory bowel diseases(IBD). However, it is unclear how disease activity, psychological symptoms and social support interact to affect HRQoL. The main purpose of this study was to examine the mediation effect of psychological symptoms in the relationship between disease activity, social support and HRQoL.

Methods

This was a cross-sectional study, which collected data using convenience sampling, between December 2016 and March 2018, from the Third XiangyaHospital of Central South University in Changsha, China. An online self-administered questionnaire (including demographic and clinical information), Inflammatory Bowel Disease Questionnaire, Disease Activity Indices scale, Hospital Anxiety and Depression Scale and Social Support Rating Scale, were administered to each participant. Descriptive statistics and Pearson’s correlations were used to summarize data, whereas PROCESS analysis was performed to examine the pre-specified mediation effect.

Results

A total of 199 patients with IBD were included. Disease activity indices (DAI) and hospital anxiety and depression (HAD) were negatively correlated with HRQoL (β = − 3.37, − 2.54 respectively, P < 0.001), while social support was positively correlated with HRQoL (β = 1.38, P < 0.01). HAD partially mediated the negative relationship between DAI and HRQoL (β = − 0.83, P < 0.001) with the mediation effect ratio of 24.6%, and completely mediated the positive relationship between social support and HRQoL (β = 1.20, P < 0.001).

Conclusions

Psychological symptoms acted as a mediator in the relationship between disease activity, social support and HRQoL. Interventions to improve HRQoL in patients with IBD should take into account the mediation effect of psychological symptoms.

Stress and the brain-gut axis in functional and chronic-inflammatory gastrointestinal diseases: A transdisciplinary challenge

The broad role of stress in the brain-gut axis is widely acknowledged, with implications for multiple prevalent health conditions that are characterized by chronic gastrointestinal symptoms. These include the functional gastrointestinal disorders (FGID), such as irritable bowel syndrome and functional dyspepsia, as well as inflammatory bowel diseases (IBD) like ulcerative colitis and Crohn's disease. Although the afferent and efferent pathways linking the gut and the brain are modulated by stress, the fields of neurogastroenterology and psychoneuroendocrinology (PNE)/ psychoneuroimmunology (PNI) remain only loosely connected. We aim to contribute to bringing these fields closer together by drawing attention to a fascinating, evolving research area, targeting an audience with a strong interest in the role of stress in health and disease. To this end, this review introduces the concept of the brain-gut axis and its major pathways, and provides a brief introduction to epidemiological and clinical aspects of FGIDs and IBD. From an interdisciplinary PNE/PNI perspective, we then detail current knowledge regarding the role of chronic and acute stress in the pathophysiology of FGID and IBD. We provide an overview of evidence regarding non-pharmacological treatment approaches that target central or peripheral stress mechanisms, and conclude with future directions, particularly those arising from recent advances in the neurosciences and discoveries surrounding the gut microbiota.

Are we choosing wisely for inflammatory bowel disease care? The IG-IBD choosing wisely campaign

BACKGROUND

The "Choosing Wisely" campaigns have the aim of promoting a better clinician-patient relationship.

AIMS

The Italian Group for the Study of Inflammatory Bowel Disease (IG-IBD) conducted a choosing wisely campaign for IBD.

METHODS

Ten IG-IBD panellists conducted the campaign through a modified Delphi process. All IG-IBD members were asked to submit five statements starting with "Do not…" addressing any IBD-related procedure or treatment the necessity of which should be questioned. All recommendations were evaluated by the panellists who prioritised each item. The top ten recommendations were prioritised again by IG-IBD members, and the top five recommendations were identified.

RESULTS

110 members (mean age 42 ± 12; 62 males) participated in the campaign. The top five recommendations were as follow: 1. Do not use corticosteroids for maintenance therapy, or without a clear indication; 2. Do not forget venous thromboembolism prophylaxis in hospitalised patients with active disease; 3. Do not treat perianal Crohn's disease with biologics without prior surgical evaluation; 4. Do not discontinue IBD-related medications during pregnancy unless specifically indicated; 5. Do not delay surgery.

CONCLUSION

The IG-IBD promoted a campaign with a bottom-up approach, identifying five recommendations that could be useful for providing a better IBD care, especially among non-IBD experts.

Efficacy and Safety in the Continued Treatment With a Biosimilar Drug in Patients Receiving Infliximab: A Systematic Review in the Context of Decision-Making From a Latin-American Country

Introduction: Biological products, including infliximab (INF), are a therapeutic option for various medical conditions. In the Peruvian Social Security (EsSalud), infliximab is approved for the treatment of rheumatoid arthritis, psoriasis, psoriatic arthropathy, ankylosing spondylitis, ulcerative colitis and Crohn’s disease (in cases refractory to conventional treatment). Biosimilars are a safe and effective alternative approved for these diseases in patients who start treatment with infliximab. Nevertheless, there are people in treatment with the biological reference product (BRP), in whom the continuing therapy with a biosimilar biological product (BBP) must be evaluated.

Objectives: To synthesize the best available evidence, calculate a preliminary financial impact and conduct technical discussions about the interchangeability into biosimilar in patients receiving treatment with original infliximab for medical conditions approved in EsSalud.

Methodology: We carried out a systematic review of controlled clinical trials. Primary search was performed in Pubmed- MEDLINE, SCOPUS, WOS, EMBASE, TRIPDATABASE, DARE, Cochrane Library, NICE, AHRQ, SMC, McMaster-PLUS, CADTH, and HSE until June-2018. We used the Cochrane Collaboration tool to assess the risk of bias. Also, we implemented a preliminary financial analysis about the impact of biosimilar introduction on institutional purchasing budget. Moreover, technical meetings with medical doctors specialized in rheumatology, gastroenterology and dermatology were held for discussing findings.

Results: In primary search, 1136 records were identified, and 357 duplicates were removed. From 799 records, we excluded 765 after title and abstract evaluation. From 14 full-text appraised documents, we included five clinical trials in the risk of bias assessment: four studies evaluated CTP-13 and one tested SB2. Two double-blind clinical trials reported no differences in efficacy and safety profiles between maintenance group (INF/INF) and interchangeability group in all diseases included (INF/CTP-13) and rheumatoid arthritis (CTP13 and SB2). In the other three studies, open-label extension of primary clinical trials, no differences were founded in efficacy and safety profiles between CTP-13/CTP-13 and INF/CTP-13 groups. In financial analysis, the inclusion of biosimilars implied savings around S/7´642,780.00 (1USD=S/3.30) on purchasing budget of EsSalud. In technical meetings, beyond certain concerns, specialists agreed with the findings.

Conclusions: Evidence from clinical trials support that there are no differences in efficacy or safety of continuing the treatment with Infliximab BRP or exchanging into its biosimilar in patients with medical conditions approved in EsSalud. Financial analysis shows that the biosimilar introduction produce savings in purchasing institutional budget. Therefore, based on cost-opportunity principle, exchanging into biosimilar in patients receiving the original Infliximab, is a valid therapeutic alternative in the Peruvian Social Security.

Impaired neurocognitive and psychomotor performance in patients with inflammatory bowel disease

Limited evidence exists regarding cognitive and psychomotor function in patients with inflammatory bowel disease (IBD). Therefore, we aimed to compare the neurocognitive and psychomotor function of 60 IBD patients with 60 age/sex-matched controls. Computer-based instrument Complex Reactinometer Drenovac (CRD) was used for assessment of cognitive domains: convergent thinking (simple mathematical tasks; CRD-11), perceptive abilities (light signal position discrimination; CRD-311) and sophisticated operative thinking (complex psychomotor coordination; CRD-411). The most important analyzed parameters were total test solving time (T_TTS); minimal time of particular test solving (T_MIN) and total number of wrong reactions (N_ER). Performance in all three cognitive tests showed statistically significantly longer T_TTS and T_MIN in IBD patients (P < 0.05), while there was no significant difference in N_ER. Aforementioned findings were adjusted for BMI, age and duration of education. Our study has shown impaired neurocognitive and psychomotor function in IBD patients compared to controls, especially in mental processing speed and mental endurance of perceptive abilities, convergent thinking and complex operative thinking.

Initial Assessment of Post-traumatic Stress in a US Cohort of Inflammatory Bowel Disease Patients

BACKGROUND

Post-traumatic stress (PTS), or the psycho-physiological response to a traumatic or life-threatening event, is implicated in medical patient outcomes. Emerging evidence suggests a complex relationship between PTS, the brain-gut axis, the gut microbiome, and immune function. Inflammatory bowel disease (IBD) may be susceptible to PTS and its subsequent impacts. To date, no study has evaluated PTS in IBD in the United States.

METHODS

Adult patients with IBD were recruited from an outpatient gastroenterology practice, via social media, and via a research recruitment website. Patients with irritable bowel syndrome (IBS) were recruited as a comparison group. Participants completed demographic and disease information, surgical and hospitalization history, and the PTSD Checklist-Civilian Version (PCL-C). Statistical analyses evaluated rates of PTS in IBD and IBS, including differences between groups for PTS severity. Regression analyses determined potential predictors of PTS.

RESULTS

One hundred eighty-eight participants (131 IBD, 57 IBS) completed the study. Thirty-two percent of IBD and 26% of IBS patients met the criteria for significant PTS symptoms based on PCL-C cutoffs. Inflammatory bowel disease patients are more likely to attribute PTS to their disease than IBS patients. Crohn's disease (CD) patients appear to be the most likely to experience PTS, including those being hospitalized or undergoing ileostomy surgery. Symptom severity is the greatest predictor of PTS for ulcerative colitis and IBS.

CONCLUSIONS

Although PTS is relevant in both IBS and IBD, IBD patients are seemingly more susceptible to PTS due their disease experiences, especially CD patients. The nature of PTS symptoms may contribute to IBD disease processes, most notably through sleep disturbance and ANS arousal. Clinicians should assess for PTS in IBD patients as standard of care, especially after a hospitalization or surgery.

Inhibition of CREB-mediated ZO-1 and activation of NF-κB-induced IL-6 by colonic epithelial MCT4 destroys intestinal barrier function

Objective

Inflammatory bowel disease (IBD) is a disorder intestinal inflammation and impaired barrier function, associated with increased epithelial expression of monocarboxylate transporter 4 (MCT4). However, the specific non‐metabolic function and clinical relevance of MCT4 in IBD remain to be fully elucidated.

Methods

Lentivirus‐mediated overexpression of MCT4 was used to assess the role of MCT4 in transcriptionally regulating ZO‐1 and IL‐6 expression by luciferase assays, WB and ChIP. IP was used to analyse the effect of MCT4 on the interaction NF‐κB‐CBP or CREB‐CBP, and these MCT4‐mediated effects were confirmed in vivo assay.

Results

We showed that ectopic expression of MCT4 inhibited ZO‐1 expression, while increased pro‐inflammatory factors expression, leading to destroy intestinal epithelial barrier function in vitro and in vivo. Mechanistically, MCT4 contributed NF‐κB p65 nuclear translocation and increased the binding of NF‐κB p65 to the promoter of IL‐6, which is attributed to MCT4 enhanced NF‐κB‐CBP interaction and dissolved CREB‐CBP complex, resulting in reduction of CREB activity and CREB‐mediated ZO‐1 expression. In addition, treatment of experimental colitis with MCT4 inhibitor α‐cyano‐4‐hydroxycinnamate (CHC) ameliorated mucosal intestinal barrier function, which was due to attenuation of pro‐inflammation factors expression and enhancement of ZO‐1 expression.

Conclusion

These findings suggested a novel role of MCT4 in controlling development of IBD and provided evidence for potential targets of IBD.

Psychological distress is highly prevalent in inflammatory bowel disease: A survey of psychological needs and attitudes

Background and Aim

Data on patient needs and access to psychological services in inflammatory bowel disease (IBD) are scarce. This study aimed to describe the levels of distress and the needs, attitudes, and access to psychological services for people within Australia against established Australian IBD Standards.

Methods

An online cross‐sectional survey was conducted with Australians ≥16 years old recruited via Crohn's & Colitis Australia membership, public and private clinics, and the Royal Flying Doctor Service. K10 was used to measure psychological distress. The Chi‐square test was used to compare those with and without distress on key variables.

Results

Overall, 731 respondents provided complete data (71.5% female, mean age 46.5 years). Overall, 50% of respondents reported distress; only 15.2% were currently seeing a mental health practitioner; only 16.1% were asked about their mental health by their IBD specialist or IBD nurse; and only 12.2% reported access to a mental health practitioner as part of their IBD service. Those with psychological distress were significantly less satisfied with their IBD care; more commonly hospitalized; had an active disease, fistula or perianal disease, pain, or fatigue; and were receiving steroids, opioids, or antidepressants (all P < 0.05). As many as 68.2% of those with severe distress were not seeing a mental health practitioner.

Conclusions

The integrated biopsychosocial model of health care, with regular mental health screening and good access to mental health professionals, is requested by people living with IBD to improve their outcomes.

Illness Perceptions and Depression Are Associated with Health-Related Quality of Life in Youth with Inflammatory Bowel Disease

BACKGROUND

In youth with inflammatory bowel disease (IBD), health-related quality of life (HRQOL) has been shown to be affected by individual disease factors and specific psychological factors. The innovative aim of this study is to examine the combined impact of psychological factors (illness perceptions, cognitive coping, anxiety, and depression) on HRQOL, over and above the associations of demographic and disease factors with HRQOL in youth with IBD.

METHOD

Data on clinical disease activity, illness perceptions, cognitive coping, anxiety, depression, and HRQOL were prospectively collected in 262 consecutive youth (age 10-20, 46.6% male) with confirmed IBD. Multiple linear regression analyses tested the associations of demographic, disease, and psychological variables with HRQOL in separate groups for Crohn's disease (CD; N = 147) and ulcerative colitis and IBD unclassified (UC/IBD-U; N = 115), using age-specific validated instruments.

RESULTS

In both disease groups, more negative illness perceptions (ß = - .412; ß = - .438, p < .001) and more depression (ß = - .454; ß = - .279, p < .001) were related to lower HRQOL. In the UC/IBD-U group, more anxiety was related to lower HRQOL (ß = - .201, p = .001). The model with the psychological variables explained a large and significant amount of variance in both groups: 74% and 83%, respectively (p < .001).

CONCLUSION

In 10-20-year-old IBD patients, negative illness perceptions and depression were significantly and more strongly associated with lower HRQOL than demographic and disease factors. Thus, it is important to integrate psychological factors in the treatment for IBD patients. To improve HRQOL in young IBD patients, psychological interventions should be targeted at negative illness perceptions and depression.

Development of a Global Rating Scale for Inflammatory Bowel Disease

Background

The Global Rating Scale (GRS) is a web-based self-assessment quality improvement tool used to identify gaps in health care, change the focus to patient-centred care and standardize care. There are four levels of achievement ranging from basic-(D) to excellent-(A) service delivery. The goal was to develop a GRS for inflammatory bowel disease (IBD) to improve the quality of care for patients on a system level.

Methods

The IBD GRS was developed through an iterative process and modeled upon the successful endoscopy GRS programs in the United Kingdom and Canada. Dimensions, items and statements were drafted based on expert opinions, patient-informed quality indicators and best available evidence, then reviewed and modified by a core committee. A working group of IBD and GRS experts voted in-person to establish consensus on the inclusion and quality of statements.

Results

Two dimensions (Clinical Quality and Quality of Patient Experience), 10 items and 89 statements made up the IBD GRS. There was a 100% response rate for each of the 40 votes for statements in the IBD GRS. All statements within each level received a mean rating score between four (agree) and five (strongly agree). Revisions agreed upon during the voting process were incorporated into the IBD GRS. Group consensus was achieved on the inclusion of statements, and 10 items were selected as standards within the two dimensions.

Conclusions

We have developed the first IBD GRS with the aim of improving quality of care through ongoing evaluations and improvements by health care teams, focusing on patient-centred care.

Patient and general population values for luminal and perianal fistulising Crohn's disease health states

BACKGROUND

In patients with Crohn's disease (CD), luminal disease activity paralleled by perianal fistulas may seriously impair health-related quality of life (HRQoL). Health utility values are not available from patients with CD that reflect the health loss associated with both luminal and perianal CD.

OBJECTIVE

To generate utilities for luminal and concomitant perianal fistulising CD health states directly from patients and from members of the general public.

METHODS

A cross-sectional survey was undertaken enrolling CD patients and a convenience sample of members of the general population. Respondents were asked to evaluate four common CD heath states [severe luminal disease (sCD), mild luminal disease (mCD), severe luminal disease with active perianal fistulas (sPFCD), and mild luminal disease with active perianal fistulas (mPFCD)] by 10-year time trade-off (TTO). In addition, patients assessed their current HRQoL by the TTO method.

RESULTS

Responses of 206 patients (40.8% with perianal fistulas) and 221 members of the general population were analysed. Mean ± SD utilities among patients for sPFCD, sCD, mPFCD and mCD states were 0.69 ± 0.33, 0.73 ± 0.31, 0.80 ± 0.29 and 0.87 ± 0.26. Corresponding values in the general public were: 0.59 ± 0.31, 0.65 ± 0.29, 0.80 ± 0.26 and 0.88 ± 0.25. Patients with active perianal fistulas, previous non-resection surgeries, and higher pain intensity scores valued their current health as worse (p < 0.05).

CONCLUSIONS

TTO is a feasible method to assess HRQoL in patients with perianal fistulising disease, often not captured by health status questionnaires. Utilities from this study are intended to support the optimization of treatment-related decision making in patients with luminal disease paralleled by active perianal fistulas.

Value-Based Health Care in Inflammatory Bowel Disease

Inflammatory bowel disease (IBD) is a chronic inflammatory disease associated with significant resource utilization and health care burden. It is emerging as a global disease affecting an increasing proportion of the population. Along with evolving epidemiological trends, the paradigm of managing IBD has also changed. With a burgeoning repertoire of therapeutic options, improved use of health informatics, and emphasis on health care value, the treatment paradigm for IBD has experienced seismic shifts. In this review, we focused on value-based health care (VBHC)-a health care model that emphasizes monitoring outcomes to emphasize patient-centered, cost-effective IBD patient care. Several quality initiatives have been developed worldwide, and successful models of care were created for proper implementation of these initiatives. Although there are significant challenges to scale these models to a national level, it is still possible to successfully implement VBHC models within health systems to improve the quality of care provided to patients with IBD.

A Novel Patient-Reported Outcome-Based Evaluation (PROBE) of Quality of Life in Patients With Inflammatory Bowel Disease

OBJECTIVES

There is increased interest in measuring patient-reported outcomes (PROs) such as quality of life (QoL) among patients with inflammatory bowel disease (IBD). We aimed to create and validate a new measure of QoL to assess the psychosocial burden of IBD using publicly available assessment tools.

METHODS

Using the Crohn's & Colitis Foundation's IBD Partners cohort, we performed several cross-sectional and longitudinal analyses to create a new PRO-based evaluation (PROBE) of QoL among patients with Crohn's disease (CD) and ulcerative colitis (UC). We used factor analysis and Pearson correlation test to identify candidate questions for inclusion, Wilcoxon rank-sum test to examine responsiveness of the PROBE to changes in disease activity, and test-retest reliability assessments in patients with stable disease activity. We also compared the PROBE to the Short Inflammatory Bowel Disease Questionnaire to assess construct validity.

RESULTS

A total of 4,854 patients (64% CD, 36% UC) completed surveys with 6 items included in the final PROBE. Compared with baseline there was a significant decrease in PROBE scores at follow-up among patients who experienced a flare for UC (25.0 vs 22.2, P = 0.001) and CD (23.1 vs 21.0, P < 0.001). Among patients with stable disease activity, Cronbach alpha was 0.87 in CD and 0.82 in UC. The PROBE correlated well with the Short Inflammatory Bowel Disease Questionnaire in CD (r = 0.88) and UC (r = 0.86).

DISCUSSION

We created a novel measure to assess QoL in patients with IBD using publicly available survey items. This new PROBE can be used to facilitate clinical care, clinical and epidemiological research, and quality improvement.

The pediatric inflammatory bowel disease INTERMED: A new clinical tool to assess psychosocial needs

OBJECTIVE

The adult INTERMED is used to determine case complexity and psychosocial needs. We developed and validated a pediatric version of the INTERMED for children and adolescents with inflammatory bowel disease (IBD) and assessed its utility in predicting healthcare utilization.

METHODS

We performed a cross-sectional study of children (aged 8-17 y) with IBD (n = 148) and their parents, seen in a hospital-based clinic. Subjects completed semi-structured interviews that were scored on the 34 pIBD-INTERMED items. To assess inter-rater reliability, 40 interviews were videotaped and scored by a second assessor. Convergent and predictive validity were assessed by examining the relation of the pIBD-INTERMED to standardized measures of psychological, social, and family functioning, disease activity, and healthcare utilization.

RESULTS

Correlational analyses supported the validity of all five pIBD-INTERMED domains with very good inter-rater reliability (median r = 0.87) and internal consistency (α = 0.91) for the total complexity index. Ratings of 2-3 on the pIBD-INTERMED "mental health/cognitive threat" item were associated with greater odds of behavior and social problems (CBCL-Internalizing scale OR = 7.27, 95% CI 2.17-24.36); CBCL-Externalizing scale OR = 24.79, 95% CI 5.00-122.84), depression (Children's Depression Inventory OR = 8.52, 95% CI 1.70-43.02) and anxiety (Multidimensional Anxiety for Children OR = 11.57, 95% CI 3.00-45.37). The pIBD-INTERMED complexity index added significantly to the prediction of healthcare utilization, beyond the contribution of disease severity.

CONCLUSIONS

The pIBD-INTERMED is a reliable and valid tool for identifying psychosocial risks and needs of children with IBD. It can be used to guide planning of individualized care and enhance interdisciplinary pediatric IBD care.

The Synergistic Role of Diet and Exercise in the Prevention, Pathogenesis, and Management of Ulcerative Colitis: An Underlying Metabolic Mechanism

Ulcerative colitis (UC) is a biologically complex condition characterized by chronic, relapsing inflammation of the gastrointestinal tract. The relative incidence of this debilitating condition is increasing and sociologically damaging outcomes are a continued reality. Several etiological theories for UC are currently under investigation, spanning between genetic and environmental determinants. From an environmental perspective, previous literature reviews have demonstrated the independent effectiveness of specific diet and exercise patterns in modifying UC immuno-pathophysiology. This article explores the synergistic role of diet and aerobic exercise in the prevention, pathogenesis, and management of UC in the context of recent immunological research. Through a unifying mechanism-that is, microbial influence of colonic inflammation and immuno-pathophysiology-the simultaneous reduction of pro-inflammatory dietary sulfurous amino acid intake (ie methionine, cysteine, homocysteine, and taurine) and the upregulation of aerobic exercise frequency (which spurs the colonization of anti-inflammatory butyrate, acetate, and propionate producing microbial taxa) demonstrate the clinical efficacy of incorporating both diet and exercise modifications for UC prevention and management through pathogenic alterations.

Inflammatory Bowel Diseases Were Associated With Risk of Sexual Dysfunction in Both Sexes: A Meta-analysis

BACKGROUND

An association between inflammatory bowel diseases (IBD) and increased susceptibility to sexual dysfunction (SD) was reported in a number of studies.

METHOD

MEDLINE (PubMed), EMBASE, and the Cochrane Library were systematically searched for all relevant studies reporting the sexual function in IBD patients. Relative risk (RR) with a 95% confidence interval (CI) was used to summarize the association between IBD and risk of SD. Subgroup and sensitivity analyses were applied to detect potential bias.

RESULTS

Overall, 351,668 male individuals and 1309 female individuals (the mean age ranged from 33.6 years to 52.4 years) were included from 8 studies (of which 4 studies provided the outcomes of both sexes). Synthesis of results revealed that IBD was significantly associated with an elevated risk of SD in male subjects (7 studies, RR = 1.41, 95% CI, 1.09-1.81, P = 0.008; heterogeneity: I2 = 80.2%, P < 0.001) and female subjects (5 studies, RR = 1.76, 95% CI, 1.28-2.42, P < 0.001; heterogeneity: I2 = 69.6%, P = 0.011). Stratified analysis by the mean age of the individuals indicated that patients with IBD with a relatively young age (male: younger than 50 years; female: younger than 40 years) exhibited a significantly increased odds of SD. Sensitivity analyses showed that no single study dominated the overall combined RR.

CONCLUSION

Evidence from this meta-analysis revealed that both male and female patients with IBD have a significantly increased risk of SD, which should remind both gastroenterologists and urologists to be aware of the potential hazardous effect of IBD for developing SD.

Current clinical issue of skin lesions in patients with inflammatory bowel disease

Inflammatory bowel disease (IBD) is associated with a number of extraintestinal complications, including skin lesions. Most reports have shown that skin lesions are found in 10-15% of IBD cases, although this depends on the definition of skin lesions. The representative skin lesions in patients with IBD are erythema nodosum, pyoderma gangrenosum, Sweet's syndrome, and so on. These lesions are often associated with IBD progression, and intestinal lesions in particular require appropriate treatment. Recently, another clinical issue regarding skin lesions in patients with IBD, a so-called paradoxical reaction, during the treatment with anti-tumor necrosis factor (TNF)-α agents has emerged. These reactions are termed paradoxical reactions because the skin lesions sometimes resemble psoriasis, although the anti-TNF-α agents have been historically used to treat psoriasis. Paradoxical reactions are reportedly found in approximately 5-10% of patients using anti-TNF-α agents and are no longer rare. Now that the use of biologics is at its culmination, reports regarding paradoxical reactions are predicted to increase in number; thus, we must recognize skin lesions with IBD patients including this type of adverse events and manage them appropriately while consulting with dermatologists.

Increased risk of periodontitis among patients with Crohn's disease: a population-based matched-cohort study

BACKGROUND

Periodontitis is a frequently cited extraintestinal manifestation of Crohn's disease (CD). Despite a plethora of investigations and a recent meta-analysis linking CD and periodontitis, no study has estimated the risk of periodontitis among CD patients with respect to a comparison group nor has any investigation analyzed the effect of CD-specific medications on the risk of periodontitis. The present cohort study compared CD patients and matched subjects without a history of inflammatory bowel disease (IBD) to estimate the effect of CD and CD-specific pharmaceutical prescriptions on the risk of developing periodontitis by leveraging a population-based dataset in Taiwan.

METHODS

We sourced 6657 CD patients and 26,628 comparison subjects without a history of IBD from the Taiwan National Health Insurance Database. Cox proportional hazards regressions were used to estimate the risk of subsequent periodontitis by CD status and pharmaceutical prescription during the follow-up period.

RESULTS

After adjusting for socioeconomic status (SES), urbanicity, selected medical co-morbidities, and CD-specific pharmaceutical prescriptions, the hazard ratio (HR) for subsequent periodontitis among patients with CD was 1.36 (95% CI = 1.25-1.48) that of comparison subjects. There was not a significant difference in risk between genders or across ages. Steroids (95% CI = 0.66-0.77) appeared to confer a protective effect and Aspirin, Plavix, and Licodin were marginally protective (95% CI = 0.76-0.95).

CONCLUSION

This is the first study to report an increased HR for subsequent periodontitis among CD patients when compared to matched comparison subjects without IBD. The protective effect of some pharmaceuticals may suggest that treatment of CD protects against periodontitis.

Quality of Life in Inflammatory Bowel Disease: A Systematic Review and Meta-analyses-Part II

BACKGROUND

There has been burgeoning interest in quality of life (QoL) in inflammatory bowel disease (IBD) in recent decades, with hundreds of studies each year now assessing this outcome. This paper is part 2 of a systematic review evaluating 5 key QoL comparisons within IBD states and relative to others without IBD. Part 1 examined QoL comparing IBD and a healthy/general population and other medically ill groups. Part 2, presented here, examines within-disease comparisons of active/inactive disease, Ulcerative colitis (UC) / Crohn's disease (CD), and change in QoL over time. Outcomes using generic versus IBD-specific QoL measures were also examined.

METHODS

Adult and pediatric studies were identified through systematic searches of 7 databases from the 1940s (where available) to October 2015.

RESULTS

Of 6173 abstracts identified, 466 were selected for final review based on controlled design and validated measurement, of which 83 unique studies (75 adult, 8 pediatric) addressed the within-disease comparisons. The pooled mean QoL scores were significantly lower in active versus inactive IBD (n = 26) and for those with CD versus UC (n = 37), consistent across IBD-specific and generic QoL measures, for almost all comparisons. There was significant improvement in QoL over time (n = 37). Study quality was generally low to moderate. The most common measures of QoL were the disease-specific Inflammatory Bowel Disease Questionnaire and generic 36-Item Short Form Survey (SF-36) (adults) and the IBD-specific IMPACT (children).

CONCLUSIONS

For adults in particular, there was strong confirmation that QoL is poorer during active disease and may be poorer for those with CD. The finding that QoL can improve over time may be encouraging for individuals with this chronic disease.
