Nonadherence to Medication in Inflammatory Bowel Disease: Rate and Reasons

Integrating Virtual Mindfulness-Based Stress Reduction Into Inflammatory Bowel Disease Care: Mixed Methods Feasibility Trial

BACKGROUND

Individuals with inflammatory bowel disease (IBD) experience cycles of aggressive physical symptoms including abdominal pain, diarrhea, and fatigue. These acute symptoms regress and return, and chronic symptoms and complications often linger. The nature of the disease can also cause individuals to experience psychological distress including symptoms of anxiety and depression; however, unlike the physical symptoms of IBD, these psychological symptoms often remain untreated.

OBJECTIVE

This study aims to evaluate the feasibility, acceptability, and effectiveness of virtual mindfulness-based stress reduction (v-MBSR) for adults with IBD.

METHODS

IBD patients with self-reported anxiety or depression were recruited from clinics in Alberta, Canada to participate in an 8-week v-MSBR intervention. Eligible patients participated in v-MBSR delivered by psychiatrists using a videoconferencing platform. Primary feasibility outcomes included trial uptake, adherence, attendance, and attrition rates. Secondary effectiveness outcomes included measures of anxiety, depression, quality of life (QoL), and mindfulness. Effectiveness data were collected at 3 time points: baseline, at intervention completion, and 6 months after completion. To further assess feasibility and acceptability, participants were invited to participate in a semistructured interview after completing v-MBSR.

RESULTS

A total of 16 of the 64 (25%) referred patients agreed to participate in v-MBSR with the most common reason for decline being a lack of time while 7 of the 16 (43.8%) participants completed the program and experienced encouraging effects including decreased anxiety and depression symptoms and increased health-related QoL with both improvements persisting at 6-month follow-up. Participants described improved coping strategies and disease management techniques as benefits of v-MBSR.

CONCLUSIONS

Patients with IBD were interested in a psychiatrist-led virtual anxiety management intervention, but results demonstrate v-MBSR may be too time intensive for some patients with IBD patients. v-MBSR was acceptable to those who completed the intervention, and improvements to anxiety, depression, and QoL were promising and sustainable. Future studies should attempt to characterize the patients with IBD who may benefit most from interventions like v-MBSR.

Development of an Inflammatory Bowel Disease-Specific Medication Adherence Instrument and Reasons for Non-adherence

BACKGROUND

Medication adherence impacts disease control in inflammatory bowel disease (IBD). Existing adherence measures such as the Morisky Medication Adherence Scale 8^© are often costly, non-medication-specific, and time-consuming.

AIMS

We aimed to develop a non-proprietary, IBD-specific medication adherence instrument and to assess reasons for suboptimal medication adherence.

METHODS

We developed the IBD Medication Adherence Tool to assess frequency of adherence and indications for missed or delayed medication doses. We co-administered the IBD Medication Adherence Tool and the Morisky Medication Adherence Scale 8^© (licensed for use) to participants enrolled in an internet-based cohort of adults with IBD and taking least one daily, oral IBD medication. We used Spearman's correlation to evaluate associations between the IBD Medication Adherence Tool and Morisky Medication Adherence Scale 8^©. We then categorized patients as sub-optimally adherent (IBD Medication Adherence Tool score 1-4) and highly adherent (score 5) and evaluated factors associated with and reasons for suboptimal adherence using multivariable analysis.

RESULTS

We evaluated 514 patients (73% female, mean age 49), of whom 21.4% had suboptimal adherence. IBD Medication Adherence Tool scores were moderately correlated with Morisky Medication Adherence Scale 8^© (r = 0.56, p < 0.001). The most commonly reported reasons for suboptimal adherence were forgetting, feeling well, and cost. Younger age and current smoking were associated with suboptimal adherence.

CONCLUSIONS

We developed a non-proprietary, IBD-specific tool to assess adherence to IBD medications, validated in a cohort of patients with IBD on daily, oral medications. Common reasons for suboptimal IBD medication adherence include forgetting, feeling well, and cost.

HIGH PREVALENCE OF NON-ADHERENCE TO ULCERATIVE COLITIS THERAPY IN REMISSION: KNOWING THE PROBLEM TO PREVENT LOSS

ABSTRACT Background Ulcerative colitis (UC) is a chronic inflammatory disease whose manifestations can drastically affect the individual’s quality of life, and therefore adherence to treatment is important in order to keep it in remission. Objective To verify the prevalence of non-adherence and the influence of sociodemographic, clinical and pharmacotherapeutic characteristics associated with non-adherence to treatment of UC in remission. Methods Cross-sectional study conducted with 90 individuals diagnosed with UC in remission. The information was collected through interviews during medical consultations at Medical Clinic of Gastroenterology of Hospital Universitário da Universidade Federal de Juiz de Fora. To verify the association of the variables under study with the outcome of interest and its measure of association, Student’s t-test or Pearson’s chi-square non-parametric test (P<0.05) was used and prevalence ratio and confidence interval were calculated. Results A high prevalence of non-adherence (77.8%) was found among patients with UC in remission. The individuals most likely to not adhere to the treatment were those aged less than 50 years, who were not engaged in paid work, with high scores for anxiety and who used more than one medication as part of the treatment of UC. Conclusion These findings reinforce that acknowledging the factors that influence the non-adherence behavior is of paramount importance for the development of strategies by health care professionals, assuring that those will be really effective to prolong, as much as possible, one of the most successful ways to maintain the UC remission period: the use of medications.

Patients' perspectives on medication for inflammatory bowel disease: a mixed-method systematic review

Inflammatory bowel disease (IBD) is a lifelong chronic disease that frequently requires long-term medical treatment to maintain remission. Patient perspectives on IBD medication are important to understand as nonadherence to IBD medication is common. We aim to synthesize the evidence about patients' perspectives on medication for IBD. A mixed-method systematic review was conducted on Scopus, EMBASE, Web of Science, and CINAHL. The convergent integrated approach to synthesis and integration of qualitative and quantitative findings was used for data analysis. Twenty-five articles from 20 countries were included in this review (20 quantitative, 3 qualitative, and 2 mixed-method studies). Patients have identified a lack of knowledge in the areas of efficacy, side effects, and characteristics of medications as key elements. Some negative views on IBD medication may also be present (e.g. the high number of pills and potential side effects). Lack of knowledge about medication for IBD was identified as a common issue for patients. Health services delivery for IBD should take into consideration these patients' perspectives. A focus on improving patient education in these areas could help empower patients and alleviate doubts resulting in better disease management and improved healthcare outcomes.

Inhibition of APE1/Ref-1 Redox Signaling Alleviates Intestinal Dysfunction and Damage to Myenteric Neurons in a Mouse Model of Spontaneous Chronic Colitis

BACKGROUND

Inflammatory bowel disease (IBD) associates with damage to the enteric nervous system (ENS), leading to gastrointestinal (GI) dysfunction. Oxidative stress is important for the pathophysiology of inflammation-induced enteric neuropathy and GI dysfunction. Apurinic/apyrimidinic endonuclease 1/redox factor-1 (APE1/Ref-1) is a dual functioning protein that is an essential regulator of the cellular response to oxidative stress. In this study, we aimed to determine whether an APE1/Ref-1 redox domain inhibitor, APX3330, alleviates inflammation-induced oxidative stress that leads to enteric neuropathy in the Winnie murine model of spontaneous chronic colitis.

METHODS

Winnie mice received APX3330 or vehicle via intraperitoneal injections over 2 weeks and were compared with C57BL/6 controls. In vivo disease activity and GI transit were evaluated. Ex vivo experiments were performed to assess functional parameters of colonic motility, immune cell infiltration, and changes to the ENS.

RESULTS

Targeting APE1/Ref-1 redox activity with APX3330 improved disease severity, reduced immune cell infiltration, restored GI function ,and provided neuroprotective effects to the enteric nervous system. Inhibition of APE1/Ref-1 redox signaling leading to reduced mitochondrial superoxide production, oxidative DNA damage, and translocation of high mobility group box 1 protein (HMGB1) was involved in neuroprotective effects of APX3330 in enteric neurons.

CONCLUSIONS

This study is the first to investigate inhibition of APE1/Ref-1's redox activity via APX3330 in an animal model of chronic intestinal inflammation. Inhibition of the redox function of APE1/Ref-1 is a novel strategy that might lead to a possible application of APX3330 for the treatment of IBD.

The Development of a Screening Tool to Identify and Classify Nonadherence in Inflammatory Bowel Disease

Background

Medication nonadherence is a challenge in chronic disease management. Tools that can both determine adherence levels and analyze patient-specific reasons for nonadherence are lacking.

Methods

Our tool was developed using 23 patient-reported items and its predictive performance was compared with the most widely used instrument in the literature.

Results

One hundred thirty-three IBD patients were included, 44 (33%) were nonadherent and 89 (67%) were adherent. Our screening question, with 87% sensitivity and 64% specificity, was followed by a 9-item survey for patients qualified as nonadherent.

Conclusions

Quantifying reasons for nonadherence can lead to more effective and personalized interventions for nonadherent patients.

Pharmacokinetic Profiling and Simultaneous Determination of Thiopurine Immunosuppressants and Folic Acid by Chromatographic Methods

With the increase in the number of medicines patients have to take, there has been a rapid rise of fixed-dose combinations (FDCs) in the last two decades. Prior to FDC development, pharmacokinetic properties of active pharmaceutical ingredients (APIs) have to be evaluated, as well as methods for their determination developed. So as to increase patient compliance in inflammatory bowel disease, three novel FDCs of thiopurine immunosuppressants and folic acid are proposed; physico-chemical and pharmacokinetic properties such as hydrophobicity, lipophilicity and plasma protein binding of all APIs are evaluated. Moreover, experimental results of different properties are compared to those computed by various on-line prediction platforms so as to evaluate the viability of the in silico approach. A simultaneous method for their determination is developed, optimized, validated and applied to commercial tablet formulations. The method has shown to be fast, selective, accurate and precise, showing potential for reliable determination of API content in proposed FDCs during its development.

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.

Epidemiology, disease burden, and treatment challenges of ulcerative colitis in Africa and the Middle East

Ulcerative colitis is an idiopathic, chronic, inflammatory bowel disorder characterized by an unpredictable course of alternating cycles of relapse and remission. Traditionally viewed as a disease of Western countries, the prevalence of ulcerative colitis is reported to be increasing in the developing world. In these regions, there is the potential to further explore the etiology of the disease, mainly through genetic studies. With this in mind, we consider available data relating to the epidemiology, clinical manifestations, and disease course of ulcerative colitis in Africa and the Middle East. Current treatment approaches in these countries are also reviewed and discussed in the context of new, small molecule, orally administered therapies. Areas covered: Available data on the epidemiology, clinical manifestations, and risk factors of ulcerative colitis in Africa and the Middle East are reviewed using a PubMed database search. Expert commentary: Epidemiologic studies from African and Middle Eastern countries suggest disease trends similar to the West, and an important health and economic burden. The management of ulcerative colitis within these developing countries is challenging, with the need to improve early diagnosis, access to healthcare, and patient education, along with facilitation of access to treatment options and improvement of medication adherence.

Determining the degree of adherence to treatment in inflammatory bowel disease patients

AIM

Since the inflammatory bowel disease (IBD) is a disorder which requires continuous drug intake to induce and maintain the remission phase, finding the barriers for low adherent group, may improve the disease phase and quality of life in those patients.

BACKGROUND

IBD is defined as a chronic immune disorder with unpredictable flares. The common treatment of these diseases can be effective for inducing and maintaining remission courses. Therefore the use of long-term medication therapy is the crucial key to prevent surgery and complications in patients with IBD.

METHODS

Morisky Medication Adherence Scales (MMAS) is used for detecting level of adherence to the medicines for 137 patients with IBD. Demographic and clinical data are recorded for all patients and quality of life has been evaluated by Short-Form 36 questionnaire in 55 patients.

RESULTS

Demographic and clinical features showed no correlation with the degree of adherence. The MMAS-8 score in the low adherent group significantly different than that in the medium and high adherer group. No relation was found statistically between level of adherence and mental or physical sates (p value=0.17, 1.2) and total quality of life (p value=0.22) in patients with IBD.

CONCLUSION

Designing smart reminder and the physician's explain about adverse effects and beneficial of medicines may be effective to confront with forgetfulness and feeling comfort with treatment. Improve a strategy in order to regular measurement of adherence to medication, provides enough information about stop taking medication.
