Elderly patients with inflammatory bowel disease: Updated review of the therapeutic landscape

Systematic review: Methotrexate-A poorly understood and underused medication in inflammatory bowel disease

BACKGROUND

Methotrexate, an immunosuppressant used for the treatment of inflammatory bowel disease (IBD) for over 30 years, remains underused compared to thiopurines.

AIMS

To review the efficacy, safety, optimal dosing and delivery regimens of methotrexate in adults with IBD.

METHODS

We conducted a systematic review of studies involving patients with IBD treated with methotrexate from inception to August 2023. All studies were included from the MEDLINE database via PubMed.

RESULTS

For Crohn's disease, we included eight randomised controlled trials (RCTs) and 17 observational studies. Parenteral methotrexate effectively increased remission rates in steroid-dependent patients at 25 mg/week for 16 weeks and at 15 mg/week for maintenance. Methotrexate can be used in combination with anti-tumour necrosis factor (TNF) agents to reduce immunogenicity. Data comparing thiopurines and methotrexate remain scarce. For ulcerative colitis (UC), we included five RCTs and 10 observational studies were included; there was no evidence to support the use of methotrexate in (UC). We extracted safety data from 17 studies; mild-to-moderate adverse effects were common. The incidence of liver fibrosis or cirrhosis was low.

CONCLUSION

Methotrexate is effective at inducing and maintaining remission in steroid-refractory Crohn's disease and can reduce anti-TNF-induced immunogenicity when used in combination therapy. Data regarding tolerance and safety are reassuring. These findings challenge preconceived ideas on methotrexate and suggest that it is a valid first-line conventional option for the treatment of mild-to-moderate Crohn's disease.

Efficacy and safety of biological treatment for inflammatory bowel disease in elderly patients: Results from a GETECCU cohort

INTRODUCTION

Biological therapies used for the treatment of inflammatory bowel disease (IBD) have shown to be effective and safe, although these results were obtained from studies involving mostly a young population, who are generally included in clinical trials. The aim of our study was to determine the efficacy and safety of the different biological treatments in the elderly population.

METHODS

Multicenter study was carried out in the GETECCU group. Patients diagnosed with IBD and aged over 65 years at the time of initiating biological therapy (infliximab, adalimumab, golimumab, ustekinumab or vedolizumab) were retrospectively included. Among the patients included, clinical response was assessed after drug induction (12 weeks of treatment) and at 52 weeks. Patients' colonoscopy data in week 52 were assessment, where available. Regarding complications, development of oncological events during follow-up and infectious processes occurring during biological treatment were collected (excluding bowel infection by cytomegalovirus).

RESULTS

A total of 1090 patients were included. After induction, at approximately 12-14 weeks of treatment, 419 patients (39.6%) were in clinical remission, 502 patients (47.4%) had responded without remission and 137 patients (12.9%) had no response. At 52 weeks of treatment 442 patients (57.1%) had achieved clinical remission, 249 patients had responded without remission (32.2%) and 53 patients had no response to the treatment (6.8%). Before 52 weeks, 129 patients (14.8%) had discontinued treatment due to inefficacy, this being significantly higher (p<0.0001) for Golimumab - 9 patients (37.5%) - compared to the other biological treatments analyzed. With respect to tumor development, an oncological event was observed in 74 patients (6.9%): 30 patients (8%) on infliximab, 23 (7.14%) on adalimumab, 3 (11.1%) on golimumab, 10 (6.4%) on ustekinumab, and 8 (3.8%) on vedolizumab. The incidence was significantly lower (p=0.04) for the vedolizumab group compared to other treatments. As regards infections, these occurred in 160 patients during treatment (14.9%), with no differences between the different biologicals used (p=0.61): 61 patients (19.4%) on infliximab, 39 (12.5%) on adalimumab, 5 (17.8%) on golimumab, 22 (14.1%) on ustekinumab, and 34 (16.5%) on vedolizumab.

CONCLUSIONS

Biological drug therapies have response rates in elderly patients similar to those described in the general population, Golimumab was the drug that was discontinued most frequently due to inefficacy. In our experience, tumor development was more frequent in patients who used anti-TNF therapies compared to other targets, although its incidence was generally low and that this is in line with younger patients based on previous literature.

Role of Age as a Predictor of Major Complications After Elective Surgery for Ulcerative Colitis

BACKGROUND

The incidence of ulcerative colitis (UC) in the elderly population is increasing. The aim of this study was to assess the degree to which age and other factors increase the risk of developing major complications in patients undergoing elective surgery for UC.

METHODS

Using the ACS-NSQIP database from 2016 to 2020, patients undergoing elective surgery for UC were divided into four categories: younger than 30, 30-49, 50-69, and 70 or older. A composite outcome was created including major complications and multivariable analysis was performed to identify factors associated with composite major complications.

RESULTS

5946 patients diagnosed with ulcerative colitis who underwent elective surgery were included in the analysis. 14.1% of all patients developed a major complication. For patients with UC, factors associated with the development of a major complication were age 50-69 (OR 1.31, P = .034), male sex (OR 1.38, P < .001), Black race (OR 1.47, P = .049), dependent status (OR 2.06, P = .028), hypoalbuminemia (OR 1.92, P < .001), preoperative steroid treatment (OR 1.27, P = .038), preoperative transfusion (OR 1.91, P < .001), open surgical approach (OR 1.44, P = .002), and partial colectomy (OR 1.51, P = .007). Specifically in patients aged 70 or older, hypoalbuminemia (OR 3.20, P < .001) and preoperative transfusion (OR 2.78, P = .019) were associated with a major complication.

CONCLUSION

Age is a risk factor for the development of a major complication in UC patients undergoing elective surgery. However, it is not the only risk factor nor is it the one that increases the risk the most.

Therapy in elderly IBD patients

INTRODUCTION

Appropriate treatment is critical in elderly inflammatory bowel disease (IBD) subjects since they are at higher risk of complications such as infections, malignancies and mortality.

EVIDENCE ACQUISITION

We conducted an extensive PubMed search for guidelines, systematic reviews and primary studies to perform a critical analysis of the existing literature on the efficacy and safety of conventional and biological therapies for elderly IBD patients.

EVIDENCE SYNTHESIS

Due to the exclusion of elderly population from clinical trials, most evidences comes from real-life studies. While aminosalicylates remain a cornerstone treatment of elderly patients with ulcerative colitis (UC), for their effectiveness and safety, their use in Crohn's disease (CD) should not be further supported. Corticosteroid use should be limited for the induction of remission, while as maintenance treatment it should be avoided, due to the low safety profile. Although as efficacious as in the younger population, immunosuppressant use has been associated with higher risk of infective/malignant issues and further use should be carefully evaluated. Biologics have demonstrated high effectiveness in the elderly. However, due to increased morbidity and mortality described in elderly subjects treated with anti-TNF alpha agents, vedolizumab and ustekinumab should be favoured over anti-TNF alpha agents.

CONCLUSIONS

Treatment of elderly IBD patients remains challenging, since comorbidities and the risk of adverse events can complicate the effectiveness and safety of therapy. Close monitoring of such patients in a multidisciplinary team is advocated to reduce the risk of infections and optimize the treatment, choosing a suitable agent.

Bilobalide attenuates lipopolysaccharide‑induced HepG2 cell injury by inhibiting TLR4‑NF‑κB signaling via the PI3K/Akt pathway

Inflammation is involved in the pathological process underlying a number of liver diseases. Bilobalide (BB) is a natural compound from Ginkgo biloba leaves that was recently demonstrated to exert hepatoprotective effects by inhibiting oxidative stress in the liver cancer cell line HepG2. The anti-inflammatory activity of BB has been reported in recent studies. The major objective of the present study was to investigate whether BB could attenuate inflammation-associated cell damage. HepG2 cells were cultured with lipopolysaccharide (LPS) and BB, and cell damage was evaluated by measuring cell viability using MTT assay. The activity of the NF-κB signaling pathway was assessed by measuring the levels of IκBα, NF-κB p65, phosphorylated (p)-IκBα, p-p65, p65 DNA-binding activity and inflammatory cytokines IL-1β, IL-6 and TNF-α. A toll-like receptor (TLR)4 inhibitor (CLI-095) was used to detect the involvement of TLR4 in cell injury caused by LPS. In addition, the PI3K/Akt inhibitor LY294002 was applied to explore the involvement of the PI3K/Akt axis in mediating the effects of BB. The results demonstrated that LPS induced HepG2 cell injury. LPS also elevated the levels of p-IκBα, p-p65, p65 DNA-binding activity and inflammatory cytokines. However, CLI-095 significantly attenuated the LPS-induced cell damage and inhibited the activation of NF-κB signaling. BB also dose-dependently attenuated the LPS-induced cell damage, activation of NF-κB signaling and TLR4 overexpression. Furthermore, it was observed that LY294002 diminished the cytoprotective effects of BB on cell injury, TLR4 expression and NF-κB activation. These findings indicated that BB could attenuate LPS-induced inflammatory injury to HepG2 cells by regulating TLR4-NF-κB signaling.

Clinical outcomes amongst elderly patients with inflammatory bowel disease

BACKGROUNDS AND AIMS

Inflammatory bowel disease (IBD) affects a growing cohort of elderly patients. Our aim was to compare the quality of care received by elderly patients with IBD with a nonelderly adult IBD population using clinical markers including steroid-free clinical remission.

METHOD

Retrospective audit of all consecutive patients attending a specialist IBD centre over a 1-year period aged >60 (elderly cohort [EC]) and 50 consecutive patients aged 30-45 years (control cohort [CC]). A follow-up survey was completed assessing current symptoms and perceptions of care.

RESULTS

One hundred thirty-nine patients were evaluated (89 EC, 50 CC). Steroid-free clinical remission was observed less commonly in the EC (58, 64%) compared with the CC (40, 80%) (P < 0.05). Biologics such as infliximab (15% EC vs 36% CC; P < 0.01) and adalimumab (14% EC vs 30% CC; P = 0.02) were used less frequently in the EC, whilst vedolizumab (6% EC vs 6% CC; P = 1) and ustekinumab (3% EC vs 2% CC; P = 1) were used at a similar frequency. Patients in the EC were less likely to have specialist IBD nursing contact (P < 0.01), smoking screening (P < 0.011) or influenza vaccinations (P < 0.006). IBD nurse contact was associated with significantly greater provision of the preventative care measures.

CONCLUSION

Elderly patients with IBD were less likely to experience steroid-free clinical remission or be prescribed biologics. Elderly patients were less likely to receive education with respect to preventative medicine. The models of care for the elderly need re-evaluation and greater incorporation with the multidisciplinary IBD team.

Real-world effectiveness and safety of ustekinumab and vedolizumab in elderly patients with Crohn's disease

Studies report favorable efficacy and safety profiles of ustekinumab (UST) and vedolizumab (VDZ) in Crohn's disease (CD), but effectiveness and safety data in elderly patients with CD is lacking. We retrospectively analyzed 78 elderly patients (39 each UST and VDZ) and found that patients on UST and VDZ experienced similar rates of clinical response, remission and mucosal healing despite high proportion of prior biologic exposure. Both UST and VDZ appear to be effective and safe in this at-risk CD population. Further large studies are needed to validate our findings.

Management of inflammatory bowel disease in the elderly: A review

The burden of Inflammatory Bowel Disease (IBD) is increasing worldwide, with a particular increase in the prevalence in the elderly population, due to the ageing of young-onset IBD as well as to the increasing incidence in elderly patients. Elderly IBD patients present specific challenges to the treating physician, as they have comorbidities, lower functional reserves, and higher risk of treatment-related complications. The diagnosis of IBD in the elderly may be difficult due to a more subtle disease presentation and to a wide range of differential diagnosis. Moreover, as these patients are often excluded from clinical trials, there is a lack of high-quality evidence to inform on the most appropriate management. Despite an increasing prevalence, the management of IBD in the elderly is still hindered by frequent misconceptions by physicians treating these patients. Due to a erroneous notion of a milder disease course and fear of adverse events, elderly IBD-patients are managed with frequent and continuous use of steroids and undertreated with effective medical therapies. In this review, we describe the principles of management of IBD in the elderly, which is a topic of increasing importance to IBD clinics, that will have to progressively adapt to care for an ageing population.

Inflammatory bowel disease in the elderly: A focus on disease characteristics and treatment patterns

Background

As the population ages, the number of elderly inflammatory bowel disease (IBD) patients is expected to increase. The clinical features and therapeutic options for young and old patients may differ, as elderly IBD patients are likely to have different comorbidities and disease characteristics. The goal of this study was to examine the clinical aspects and therapeutic choices for elderly Saudi IBD patients.

Methods

We conducted a retrospective study aimed at describing the demographic, clinical, and management characteristics of IBD in elderly patients (≥60 years) who followed up at King Abdulaziz University Hospital (KAUH), Jeddah, Saudi Arabia. The data was extracted from the KAUH inflammatory bowel disease information system (IBDIS) registry. The primary outcome was to describe disease characteristics in accordance with the Montréal classification and the secondary outcomes were to describe treatment patterns and identify significant clinical associations.

Results

Our data were collected from 76 patients who fulfilled the study inclusion criteria. Females outnumbered males (53.9% vs 46.1%) and the mean age was 51.5 ± 9.7 years. Essential hypertension (26.3%) was the most common comorbidity followed by diabetes mellitus (23.6%), and malignant neoplasms (9.21%). More than half of the patients with Crohn's disease (CD) had disease onset after forty years of age. The most common form of disease distribution was ileocolonic disease (64.7%). Less than 17% of patients had a penetrating disease phenotype. About 88 percent of patients with UC presented >40 years of age. Approximately, half of the cohort had left-sided ulcerative colitis (UC) (48%), followed by pancolitis (40%). The most prescribed medication class for IBD was 5-aminosalicylic acid (5-ASA) derivatives (56.58%) followed by corticosteroids and immunosuppressive drugs.

Conclusions

In Saudi Arabia, age-specific concerns including comorbidities and polypharmacy remain the major challenges in the management of elderly IBD patients.

Risk of Infection in Elderly Patients with Inflammatory Bowel Disease under biologics: A Prospective, Multicenter, Observational, One-Year follow-up comparative study

OBJECTIVES

The emergence of biologics has improved the course of inflammatory bowel diseases (IBD) in the elderly population despite a potential higher risk of infections. We conducted a one-year, prospective, multicenter, observational study to determine the frequency of occurrence of at least one infectious event in elderly IBD patients under anti-TNF therapy compared with that in elderly patients under vedolizumab or ustekinumab therapies .

METHODS

All IBD patients over 65 years exposed to anti-TNF, vedolizumab or ustekinumab therapies were included. The primary endpoint was the prevalence of at least one infection during the whole one year follow-up.

RESULTS

Among the 207 consecutive elderly IBD patients prospectively enrolled, 113 were treated with anti-TNF and 94 with vedolizumab (n=63) or ustekinumab (n=31) (median age 71 years, 112 Crohn's disease). The Charlson index was similar between patients under anti-TNF and those under vedolizumab or ustekinumab as well as the proportion of patients under combination therapy and under concomitant steroid therapy did not differ between both both groups. The prevalence of infections was similar in patients under anti-TNF and in those under vedolizumab or ustekinumab (29% versus 28%, respectively; p=0.81). There was no difference in terms of type and severity of infection and of infection-related hospitalization rate. In multivariate regression analysis, only the Charlson comorbidity index (≥ 1) was identified as a significant and independent risk factor of infection (p=0.03).

CONCLUSION

Around 30 % of elderly patients with IBD under biologics experienced at least one infection during the one-year study follow-up period. The risk of occurrence of infection does not differ between anti-TNF and vedolizumab or ustekinumab therapies, and only the associated comorbidity was linked with the risk of infection.

Clinical characteristics of elderly-onset inflammatory bowel disease

Inflammatory bowel disease (IBD) is a group of chronic non-specific intestinal inflammatory diseases whose etiology has not been elucidated. The prevalence of elderly-onset IBD is increasing; however, its disease phenotype, pathophysiology, and clinical characteristics are different from those of adult-onset IBD. In order to better manage elderly IBD patients, it is becoming increasingly important to accurately describe the unique characteristics of elderly-onset IBD. Therefore, this article, based on the domestic and foreign literature reports from 2017 to now, describes the characteristics of elderly-onset IBD with regard to pathogenesis, epidemiological characteristics, clinical features, and treatment.

Systematic Review: The Impact and Importance of Body Composition in Inflammatory Bowel Disease

BACKGROUND AND AIMS

Alterations in body composition are common in inflammatory bowel disease [IBD] and have been associated with differences in patient outcomes. We sought to consolidate knowledge on the impact and importance of body composition in IBD.

METHODS

We performed a systematic search of MEDLINE, EMBASE and conference proceedings by combining two key research themes: inflammatory bowel disease and body composition.

RESULTS

Fifty-five studies were included in this review. Thirty-one focused on the impact of IBD on body composition with a total of 2279 patients with a mean age 38.4 years. Of these, 1071 [47%] were male. In total, 1470 [64.5%] patients had Crohn's disease and 809 [35.5%] had ulcerative colitis. Notably, fat mass and fat-free mass were reduced, and higher rates of sarcopaenia were observed in those with active IBD compared with those in clinical remission and healthy controls. Twenty-four additional studies focused on the impact of derangements in body composition on IBD outcomes. Alterations in body composition in IBD are associated with poorer prognoses including higher rates of surgical intervention, post-operative complications and reduced muscle strength. In addition, higher rates of early treatment failure and primary non-response are seen in patients with myopaenia.

CONCLUSIONS

Patients with IBD have alterations in body composition parameters in active disease and clinical remission. The impacts of body composition on disease outcome and therapy are broad and require further investigation. The augmentation of body composition parameters in the clinical setting has the potential to improve IBD outcomes in the future.

Real-World Effectiveness and Safety of Ustekinumab in Elderly Crohn's Disease Patients

INTRODUCTION

The efficacy and safety profile of ustekinumab (UST) in Crohn's disease (CD) is favorable; however, data in elderly patients are lacking. We aimed to assess the safety and efficacy of UST in elderly CD.

METHODS

We performed a retrospective cohort study of CD patients classified as elderly (age ≥ 65 years at UST initiation) or nonelderly (<65 years) treated at a large, tertiary referral center. Outcomes assessed were clinical (measured by physician global assessment [PGA]) and steroid-free response, remission, adverse events, and postsurgical complications were compared by age category. Multivariable regression modeling and survival analysis was also performed.

RESULTS

In total, 117 patients (elderly n = 39, nonelderly n = 78) were included in the study. Elderly patients had predominantly moderate disease (87.2%), while nonelderly had a higher proportion of severe disease activity (44.9%) (p = 0.001), though no differences in baseline endoscopic activity, prior biologic use, or steroid or immunomodulator use at baseline existed (p > 0.05 all). While nearly 90% patients in both groups experienced clinical response to UST, compared to nonelderly, elderly patients were less likely to achieve complete clinical remission (28.2% vs. 52.6%, p = 0.01). On regression modeling, age was not associated with clinical outcomes (p > 0.05 all). Mucosal healing was achieved in 26% elderly and 30% nonelderly patients (p = 0.74). There were no significant differences in infusion reactions (2.6% vs. 6.4%, p = 0.77), infection (5.2% vs. 7.7%, p = 0.7), or postsurgical complications (p = 0.99) by age category.

CONCLUSION

UST is safe and effective in elderly CD. Although limited by sample size and retrospective design, such real-world data can inform biologic positioning in this IBD population.

Ustekinumab does not increase risk of new or recurrent cancer in inflammatory bowel disease patients with prior malignancy

BACKGROUND AND AIM

There is limited data on the rate of new or recurrent cancer in patients with inflammatory bowel disease (IBD) and a history of prior or current malignancy who are initiated on biologic therapies. Furthermore, there is no data on this topic in patients using ustekinumab.

METHODS

The retrospective study included 341 patients with IBD and a history of cancer who were subsequently treated with vedolizumab (VDZ; n = 34), ustekinumab (USK; n = 27), tumor necrosis factor α antagonists (anti-TNF; n = 99), or had no immunosuppressive therapy (control; n = 181). Cox proportional hazard models were developed to determine the independent effect of post-cancer immunosuppressive treatment on the occurrence of incident cancer.

RESULTS

Over a median of 5.2 person-years of follow up, cancer recurrence occurred in only one patient on anti-TNF, while new cancers developed in one patient on VDZ, three patients on USK, and six patients on anti-TNF, corresponding to cancer rates of 0.4, 1.8, and 0.7 per 100 person-years, respectively. The rate of incident cancer in control patients was 2.4 per 100 person-years and included 18 new and 9 recurrent cancers. Compared with controls, a stepwise Cox proportional hazards model adjusting for significant covariates found no increased risk of incident cancer in patients receiving post-malignancy treatment with USK (hazard ratio [HR] 0.88; 95% confidence interval [CI] 0.25-3.03), VDZ (HR 0.18; 95% CI 0.03-1.35), or anti-TNF (HR 0.47; 95% CI 0.20-1.12).

CONCLUSION

Use of biologic therapy in IBD patients with a previous history of malignancy was not associated with an increased risk of new or recurrent cancer.

Crohn's Disease of the Elderly: Unique Biology and Therapeutic Efficacy and Safety

The incidence and prevalence of inflammatory bowel disease (IBD) is increasing in the elderly population. Compared with patients with onset during younger years, patients with elderly-onset IBD have a distinct clinical presentation, disease phenotype, and natural history. Genetics contribute less to pathogenesis of disease, whereas aging-related biological changes, such as immunosenescence and dysbiosis, are associated with elderly-onset IBD. Frailty is an increasingly recognized predictor of adverse outcomes. As an increasingly wider array of biologic and small molecule therapeutic options becomes available, data regarding efficacy and safety of these agents in patients are paramount given the unique characteristics of this population.

The present and future of gastroenterology and hepatology: an international SWOT analysis (the GASTROSWOT project)

GASTROSWOT is a strategic analysis of the current and projected states of the different subspecialties in gastroenterology that aims to provide guidance for research, clinical, and financial planning in gastroenterology. We executed a consensus-based international strengths, weaknesses, opportunities, and threats (SWOT) analysis. Four general coordinators, six field coordinators, and 12 experts participated in the study. SWOTs were provided for the following fields: neurogastroenterology, functional gastrointestinal disorders, and upper gastrointestinal diseases; inflammatory bowel disease; pancreatology and biliary diseases; endoscopy; gastrointestinal oncology; and hepatology. The GASTROSWOT analysis highlights the following in the current state of the field of gastroenterology: the incidence and complexity of several gastrointestinal diseases, including malignancies, are increasing; the COVID-19 pandemic has affected patient care on several levels; and with the advent of technical innovations in gastroenterology, a well trained workforce and strategic planning are required to optimise health-care utilisation. The analysis calls attention to the following in the future of gastroenterology: artificial intelligence and the use of big data will speed up discovery and smarter health-care provision in the field; the growth and diversification of gastroenterological specialties will improve specialised care for patients, but could promote fragmentation of care and health system inefficiencies; and furthermore, thoughtful planning is needed to reach an effective balance between the need for subspecialists and the value of general gastroenterology services.

Is it time to include older adults in inflammatory bowel disease trials? A call for action

The therapeutic management of older patients with inflammatory bowel disease (IBD) is challenging, particularly because of the absence of evidence-based guidelines for these patients, who seem to frequently be excluded from clinical trials. In this systematic review we investigated the exclusion of older patients with IBD from phase 3 studies registered on PubMed and ClinicalTrials.gov, by assessing the upper limit of age exclusion criteria and the percentage of patients older than 65 years included in the trials. Exclusion criteria other than age were also recorded, and comorbidities were analysed separately. Our review of 222 phase 3 studies shows that older patients are frequently excluded from IBD clinical trials because of their age, which was used as an exclusion criterion in 129 (58%) of the 222 assessed trials. Of the 32 trials that detailed the percentage of included patients who were 65 years or older, only 763 (5·4%) patients of the 14 124 patients included were older than 65 years. In addition to age, patients were also excluded because of comorbidities (mainly renal, hepatic, and cardiovascular, and used as an exclusion criterion in 76% of trials), a history of dysplasia (45% of trials), and previous treatment for IBD (19% of trials). We propose a three-step process that should enable the inclusion of all older patients in IBD clinical trials, regardless of their age, comorbidities, and frailty.

A recombinant glucocorticoid-induced leucine zipper protein ameliorates symptoms of dextran sulfate sodium-induced colitis by improving intestinal permeability

Inflammatory bowel diseases (IBDs) are chronic inflammatory disorders characterized by relapsing intestinal inflammation, but many details of pathogenesis remain to be fully unraveled. Glucocorticoid (GC)-induced leucine zipper (GILZ) is a mediator of the anti-inflammatory effects of GCs, the most powerful drugs for IBD treatment, but they cause several unwanted side effects. The fusion protein TAT-GILZ has been successfully used in some pre-clinical models of inflammatory and autoimmune diseases. To test the efficacy of TAT-GILZ for treating dextran sulfate sodium (DSS)-induced colitis and explore its impact on the gut microbiome, colitis was induced by DSS in C57BL/6J mice and treated with TAT-GILZ or dexamethasone. Various hallmarks of colitis were analyzed, including disease activity index, gut permeability, and expression of pro-inflammatory cytokines and tight junction proteins. TAT-GILZ treatment showed a therapeutic effect when administered after the onset of colitis. Its efficacy was associated with improved gut permeability, as evidenced by zonula occludens-1 and CD74 upregulation in inflamed colonic tissue. TAT-GILZ also ameliorated the changes in the gut microbiota induced by the DSS, thus potentially providing an optimal environment for colonization of the mucosa surface by beneficial bacteria. Overall, our results demonstrated for the first time that TAT-GILZ treatment proved effective after disease onset allowing restoration of gut permeability, a key pathogenic feature of colitis. Additionally, TAT-GILZ restored gut dysbiosis, thereby contributing to healing mechanisms. Interestingly, we found unprecedented effects of exogenous GILZ that did not overlap with those of GCs.

Short-Term Outcomes for Restorative and Non-Restorative Proctocolectomy in Older Adults

BACKGROUND

Curative surgery for ulcerative colitis can be subdivided into restorative (with pouch and anastomosis) and non-restorative operations. Restorative surgery in older adults is controversial, due to concerns about surgical risk and long-term functional outcome. The goal of this study is to compare 30-day outcomes for restorative and non-restorative surgery in older adults with ulcerative colitis.

METHODS

Data were obtained from the American College of Surgeons National Surgical Quality Initiative Program from 2012-2018. Patients were included if they were >65 years old and had ulcerative colitis. Restorative and non-restorative surgeries were defined with procedure codes. Patient characteristics and adverse surgical outcomes were compared between restorative and non-restorative surgeries utilizing chi-square tests and Fisher's exact tests. Multivariate logistic regression models were constructed to evaluate the association of restorative versus non-restorative surgery with adverse surgical outcomes while adjusting for potential confounders.

RESULTS

Of 392 total patients, 95 had restorative and 297 had non-restorative surgery. Patients undergoing restorative surgery, compared to non-restorative surgery, were significantly younger (P<0.01), had lower incidences of steroid usage (P<0.001) and higher rates of readmission (P = 0.02). There were no differences in post-operative complications between the groups in both unadjusted analyses and covariate-adjusted regression analysis (P > 0.05).

CONCLUSION

In carefully selected older patients with ulcerative colitis, restorative surgery is associated with increased readmission, but otherwise similar rates of morbidity or mortality compared to non-restorative surgery. Data regarding postoperative functional outcome and quality of life are also needed to help select the most appropriate curative option for older adults.

The elderly IBD patient in the modern era: changing paradigms in risk stratification and therapeutic management

The incidence and prevalence of inflammatory bowel disease (IBD) is rising in the elderly population. Compared with patients with onset during their younger years, patients with elderly onset IBD have a distinct clinical presentation, disease phenotype, and natural history. Genetics contribute less to pathogenesis of disease, whereas biological changes associated with aging including immunosenescence, dysbiosis, and frailty have a greater impact on disease outcomes. With the advent of an increasingly wider array of biologic and small-molecule therapeutic options, data regarding efficacy and safety of these agents in elderly IBD patients specifically are paramount, given the unique characteristics of this population.

Trends and Outcomes of Hip Fracture Hospitalization Among Medicare Beneficiaries with Inflammatory Bowel Disease, 2000-2017

BACKGROUND

Patients with inflammatory bowel disease (IBD) have a higher risk of hip fracture, but lower likelihood of having arthroplasties than non-IBD patients in Nationwide Inpatient Sample. Little is known about hip fracture-associated hospitalization outcomes.

AIMS

We assessed the trends in hip fracture hospitalization rates from 2000 to 2017 and estimated 30-day readmission, 30-day mortality, and length of stay in 2016 and 2017.

METHODS

We estimated trends of age-adjusted hospitalization rates using a piecewise linear regression. Medicare beneficiaries aged ≥ 66 years with Crohn's disease (CD, n = 2014) or ulcerative colitis (UC, n = 2971) hospitalized for hip fracture were identified. We performed propensity score matching to create 1:3 matched samples on age, race/ethnicity, sex, and chronic conditions and compared hospitalization outcomes between matched samples.

RESULTS

In 2017, the age-adjusted hospitalization rates (per 100) were 1.15 [95% CI = (1.07-1.24)] for CD, 0.86 [95% CI = (0.82-0.89)] for UC, and 0.59 [95% CI = (0.59-0.59)] for no IBD. The hospitalization rates for CD and UC decreased from 2000 to 2012 and then increased from 2012 to 2017. Compared to matched cohorts, CD patients had longer hospital stays (5.55 days vs. 5.30 days, p = 0.01); UC patients were more likely to have 30-day readmissions (17.27% vs. 13.71%, p < 0.001), longer hospital stays (5.59 days vs. 5.40 days, p = 0.02), and less likely to have 30-day mortality (3.77% vs. 5.15%, p = 0.003).

CONCLUSIONS

Prevention of hip fracture is important for older adults with IBD, especially CD. Strategies that improve quality of inpatient care for IBD patients hospitalized for hip fracture should be considered.

Ciclosporin or Infliximab as Rescue Therapy in Acute Glucorticosteroid-Refractory Ulcerative Colitis: Systematic Review and Network Meta-Analysis

BACKGROUND

Despite randomized controlled trials [RCTs] and trial-based meta-analyses, the optimal rescue therapy for patients with acute glucorticosteroid-refractory ulcerative colitis [UC], to avoid colectomy and improve long-term outcomes, remains unclear. We conducted a network meta-analysis examining this issue.

METHODS

We searched MEDLINE, EMBASE, EMBASE Classic and the Cochrane central register up to June 2020. We included RCTs comparing ciclosporin and infliximab, either with each other or with placebo, in patients with glucorticosteroid-refractory UC.

RESULTS

We identified seven RCTs containing 534 patients [415 in head-to-head trials of ciclosporin vs infliximab]. Risk of colectomy at ≤ 1 month was reduced significantly with both treatments, compared with placebo (relative risk [RR] of colectomy with infliximab vs placebo = 0.37; 95% confidence interval [CI] 0.21-0.65, RR with ciclosporin vs placebo = 0.40; 95% CI 0.21-0.77). In terms of colectomy between > 1 month and < 1 year, both drugs ranked equally [P-score 0.75]. Neither treatment was more effective than placebo in reducing the risk of colectomy at ≥ 1 year. Both ciclosporin and infliximab were significantly more efficacious than placebo in achieving a response. Neither treatment was more effective than placebo in inducing remission, nor more likely to cause serious adverse events than placebo.

CONCLUSIONS

Both ciclosporin and infliximab were superior to placebo in terms of response to therapy and avoiding colectomy up to 1 year, with no significant differences in efficacy or safety between the two. Ciclosporin remains a valid option to treat refractory UC patients, especially those who do not respond to previous treatment with infliximab, or as a bridge to other biological therapies.
