The Combination of Patient-Reported Clinical Symptoms and an Endoscopic Score Correlates Well with Health-Related Quality of Life in Patients with Ulcerative Colitis

Patient experiences in ulcerative colitis: conceptual model and review of patient-reported outcome measures

PURPOSE

To identify symptoms and their impacts on daily functioning and health-related quality of life (HRQoL) experienced by adult patients with ulcerative colitis (UC) and evaluate patient-reported outcome (PRO) measures for UC clinical studies.

METHODS

A conceptual model of symptoms and impacts of UC were developed from a literature review. PRO measures were identified from the literature, clinical trials databases, health technology assessment submissions, and regulatory label claims, and were selected for conceptual analysis based on disease specificity and use across information sources. PRO measures covering the most concepts when mapped against the conceptual model were assessed for gaps in psychometric properties using Food and Drug Administration (FDA) guidance and consensus-based standards for the selection of health measurement instruments (COSMIN) criteria.

RESULTS

The conceptual model grouped the 52 symptom concepts and 72 proximal and distal impacts into eight, two, and five dimensions, respectively. Of 65 PRO measures identified, eight underwent conceptual analysis. Measures covering the most concepts and assessed for psychometric properties were the Inflammatory Bowel Disease Questionnaire, Symptoms and Impacts Questionnaire for UC, UC-PRO symptoms modules, UC-PRO impact modules, and Crohn's and UC Questionnaire; all had good or excellent support for content validity. The UC-PRO Signs and Symptoms fully met FDA guidance and COSMIN criteria for content validity and most psychometric properties.

CONCLUSION

Existing PRO measures assess concepts relevant to patients with UC, but all PRO measures reviewed require further psychometric evaluation to demonstrate they are fit for purpose.

Translation and cross-cultural adaptation of the Persian version of inflammatory bowel disease-fatigue (IBD-F) self-assessment questionnaire

BACKGROUND

This study appraises the psychometrics properties of the Inflammatory bowel disease-fatigue (IBD-F) Persian version questionnaire.

METHODS

The original IBD-F questionnaire was translated into the Persian version in a standard forward-back manner. The validation was performed through the face, content, and construct validity. Fifteen experts scored each item's necessity on an ordinal Likert scale of three; then, the content validity ratio was calculated using the Lawshe formula. Eight judges from pre-defined panel rated each item on an ordinal 4-point Likert scale concerning its relevancy, clarity, and simplicity for individual-CVI calculation. The mean individual-CVI was considered as the Scale-CVI for each domain. Twenty lay experts (selected from the target population) were asked to express their opinion on each item's importance by scoring on a 5-point Likert scale; subsequently, face validity was determined by the impact score formula. The questions that had minimum values of CVR, CVI, and impact score were retained in the final version of the questionnaire for reliability evaluation. Construct validity was evaluated via Confirmatory Factor Analysis. Internal consistency and test-retest reliability were checked using Cronbach's α and intraclass correlation coefficients (ICC). Fifty-four patients recruited based on inclusion and exclusion criteria to participate in the reliability analysis.

RESULTS

All the questions received the qualified values of CVR (exceeding 0.49 points) and impact score (more than 1.5 points) and were retained in the questionnaire; however, revisions were made for questions with a CVI 0.7-0.9 for clarity and simplicity. The result demonstrated relative goodness CFA and proper internal consistency, as Cronbach's α coefficient was 0.964 for the test (0.845 and 0.963 for the first and second part of the questionnaire, respectively (and 0.888 for the re-test (0.793 and 0.876 for the first and second section of the questionnaire, respectively). The ICC values between test and re-test for the first and second part and the whole questionnaire were obtained as 0.904, 0.922, and 0.921, respectively.

CONCLUSION

The Persian version of the IBD-F questionnaire was valid and reliable; thus, an appropriate scale was deemed to measure fatigue (severity, frequency, and impact on daily activities).

Impact of adalimumab on disease burden in moderate-to-severe ulcerative colitis patients: The one-year, real-world UCanADA study

BACKGROUND

A gap remains in documenting the impact of anti-tumor necrosis factor therapy on disease burden in ulcerative colitis (UC) patients treated in a real-world setting. The use of patient-reported outcomes (PROs) has been discussed as a primary endpoint in the context of the FDA PRO Guidance, for labelling purposes. Specifically, the efficacy and safety of adalimumab have been demonstrated in pivotal trials; however, data are needed to understand how clinical results translate into improvements in key aspects of the daily lives of UC patients, such as symptoms, health-related quality of life (HRQoL), and disability.

AIM

To assess real-world effectiveness of adalimumab on PRO measures in patients with moderate-to-severe UC.

METHODS

UCanADA was a single arm, prospective, 1-year multicenter Canadian post-marketing observational study in which multiple PRO questionnaires were completed—with psychologic distress/depression symptoms as the primary endpoint—by patients with moderate-to-severe UC. Assessments were performed during patients’ routine care visit schedule, which was at the initiation of adalimumab (baseline), after induction (approximately 8 wk), and 52 wk after baseline. Additional optional assessments between weeks 8 and 52 were collected at least once but no more than two times during this period. Serious safety events and per-protocol adverse events were collected.

RESULTS

From 23 Canadian centres, 100 patients were enrolled and 48 completed the study. Measured with the Patient Health Questionnaire–9 items at week 52, 61.5% (40/65) [95% confidence interval (CI): 49.7%-73.4%] of the patients improved in psychologic distress/depression symptoms, which was slightly higher in completers [65.9% (29/44); 95%CI: 51.9%-79.9%)]. At week 52, clinical response and clinical remission were achieved respectively by 65.7% (44/73) and 47.8% (32/73) of the patients. The odds of improving depressive symptoms for those achieving a clinical remission at week 52 was 7.94 higher compared with those not achieving a clinical remission (CI: 1.42, 44.41; P = 0.018). Significant changes from baseline to weeks 8 and 52 were observed in disability, HRQoL, and fatigue. Meaningful improvement was reported in work impairment.

CONCLUSION

At week 52, over 60% of the UCanADA patients had depressive symptoms significantly reduced, as well as HRQoL, fatigue symptoms, and work impairment improved. No new safety signals were detected.

Endoscopic mucosal healing and histologic remission in ulcerative colitis: a systematic literature review of clinical, quality-of-life and economic outcomes

OBJECTIVE

This systematic literature review (SLR) assessed the effects of endoscopic mucosal healing and histologic remission on clinical, quality-of-life (QoL), and economic outcomes in adults with ulcerative colitis (UC) in the real-world setting.

METHODS

Literature searches of Embase and MEDLINE (6 July 2020) and conference proceedings (2017-2020) were performed according to Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. Eligible studies included adults with UC with documented endoscopic mucosal healing or histologic remission. Clinical, QoL, and economic outcomes were extracted and narratively synthesized.

RESULTS

Of 1603 studies screened, 25 met eligibility criteria and collectively included 2813 patients (mean age: 34-60 years). The most commonly reported indices were Mayo endoscopic score (MES) for endoscopic mucosal healing (n = 22, 88%) and Geboes score (n = 5, 20%) for histologic outcomes. The most frequently reported clinical outcome was relapse-free survival (n = 15, 60%). Less commonly reported outcomes were avoidance of colectomy (n = 5, 20%), hospitalization (n = 4, 16%), clinical remission (n = 4, 16%), and steroid-free clinical remission (n = 3, 12%). Most studies reported relapse-free survival rates up to 50% over 6-48 months of follow-up in endoscopic mucosal healing cohorts. Studies reporting results by MES demonstrated higher relapse-free survival rates among patients with MES 0 than with MES 1 (32%-100% vs 26%-86%, respectively). Similarly, patients with histologic remission had better relapse-free survival rates over 12-24 months of follow-up compared with those without histologic remission (72%-91% vs 40%-63%, respectively). Rates of clinical remission, steroid-free remission, hospitalization, and colectomy avoidance were also better among patients with endoscopic mucosal healing and histologic remission. Two studies examining QoL reported endoscopic mucosal healing was associated with improved QoL. No study reported economic outcomes.

CONCLUSIONS

This SLR demonstrated consistent evidence of improved clinical outcomes among UC patients with endoscopic mucosal healing and histologic remission.

Validation of a claims-based algorithm to identify cases of ulcerative colitis in Japan

BACKGROUND AND AIM

The prevalence of ulcerative colitis (UC) is increasing in Japan. Validated claims-based definitions are required to investigate the epidemiology of UC and its treatment and disease course in clinical practice. This study aimed to develop a claims-based algorithm for UC in Japan.

METHODS

A committee of epidemiologists, gastroenterologists, and internal medicine physicians developed a claims-based definition for UC, based on diagnostic codes and claims for UC treatments, procedures (cytapheresis), or surgery (postoperative claims). Claims data and medical records for a random sample of 200 cases per site at two large tertiary care academic centers in Japan were used to calculate the positive predictive value (PPV) of the algorithm for three gold standards of diagnosis, defined as physician diagnosis in the medical records, adjudicated cases, or registration in the Japanese Intractable Disease Registry (IDR).

RESULTS

Overall, 1139 claims-defined UC cases were identified. Among 393 randomly sampled cases (mean age 44; 48% female), 94% had received ≥ 1 systemic treatment (immunosuppressants, tumor necrosis factor inhibitors, corticosteroids, or antidiarrheals), 7% had cytapheresis, and 7% had postoperative claims. When physician diagnosis was used as a gold standard, PPV was 90.6% (95% confidence interval [CI]: 87.7-93.5). PPV with expert adjudication was also 90.6% (95% CI: 87.7-93.5). PPVs with enrollment in the IDR as gold standard were lower at 41.5% (95% CI: 36.6-46.3) due to incomplete case registration.

CONCLUSIONS

The claims-based algorithm developed for use in Japan is likely to identify UC cases with high PPV for clinical studies using administrative claims databases.

Healthcare Needs and Perceptions of People Living With Inflammatory Bowel Disease in Australia: A Mixed-Methods Study

Background

Crohn's disease (CD), ulcerative colitis (UC), and indeterminate colitis are inflammatory bowel diseases (IBDs) that adversely affect the healthcare needs and quality of life (QoL) of people with IBD. The aim of this study was to explore the needs and perceptions of people with IBD in a primary care setting.

Methods

This sequential explanatory mixed-methods study consisted of a cross-sectional survey (included validated tools), followed by semistructured interviews on participants' perceptions: IBD management, healthcare professionals, IBD care, flare management, and pharmacist's IBD roles.

Results

Sixty-seven participants completed the survey, and 8 completed interviews. Quantitative findings: Age at diagnosis had significant association with medication nonadherence (P = .04), QoL (P = .04), and disease control (P = .01) among the respondents. The odds of medication nonadherence were 8 times (adjusted odds ratio [AOR] = 8.04, 95% confidence interval [CI] = 1.08, 60.10) higher among younger participants aged <30 years. Those diagnosed with CD (P = .02) reported more likely to have unfavorable perceptions of pharmacists' role in managing their IBD (AOR = 9.45, 95% CI = 1.57, 56.62) than those with UC and indeterminate colitis. Qualitative findings: General practitioners were considered the most important care provider and the first point of contact for patients in managing all aspects of IBD. Participants identified their key need to be timely access to specialized IBD care and found that other primary healthcare professionals lacked disease-specific knowledge for managing IBD.

Conclusions

Primary healthcare professionals are well positioned but need targeted training to influence the needs of IBD patients. The specialty role of an IBD educator could complement existing services to deliver and address patient-specific care.

Burden of Inflammatory Bowel Disease on Patient Mood, Fatigue, Work, and Health-Related Quality of Life in Thailand: A Case-Control Study

Background

Inflammatory bowel disease (IBD) has become an emerging disease in Asia. The burden of disease affects health-related quality of life (HRQoL), economics, and society. We compared HRQoL of IBD patients with/without active disease to that of the general population.

Methods

Consecutive patients with active disease and patients in clinical remission were prospectively recruited. For each IBD patient, an age- and sex-matched healthy control was invited. Active disease was defined as patient-reported clinical symptoms (ClinPRO) with endoscopic inflammation. All participants completed five questionnaires: (1) Short IBD Questionnaire (SIBDQ); (2) Hospital Anxiety and Depression Scale (HADS); (3) Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-Fatigue); (4) Work Productivity and Activity Impairment questionnaire (WPAI); and (5) EuroQol 5-Dimension 5-Level scale (EQ5D5L). Multiple regression analyses were used to assess differences in HRQoL scores between IBD patients and controls.

Results

A total of 418 participants (209 IBD, 209 controls) were included. There were 101 patients with active disease and 108 patients in clinical remission. Regarding patients with active disease compared with controls, there was a significant mean difference in scores (95% CI) of 12.3 (9.5-15.2) on the SIBDQ; 6.7 (4.7-8.8), FACIT-fatigue; 1.6 (0.6-2.7), HADS-anxiety; 1.6 (0.8-2.4), HADS-depression; 20.3% (13.0%-27.7%), work productivity impairment; and 0.089 (0.045-0.134), EQ5Q5L (P < .05, all comparisons). Regarding patients in clinical remission compared with controls, none of these mean differences achieved a minimal clinically important difference.

Conclusions

Active IBD has a negative impact on HRQoL, whereas patients in clinical remission showed no clinically significant difference from the general population on HRQoL.

Twenty-five years of biologicals in IBD: What´s all the hype about?

Twenty-five years ago the field was revolutionized by the introduction of infliximab as the first hybrid anti-TNF-antibody. Subsequently, other humanized anti-TNFs were developed and marketed, followed by antibodies to new targets including integrins (vedolizumab) and interleukin 12/23 (ustekinumab). All these so-called biologicals were shown in registrational trials to induce remission superior to placebo but consistently were effective in only a minority of patients. Even though in most trials only the responders were selected to continue on the respective medication for maintenance, many experienced a secondary loss of response and only a minority of usually <25% of the initial cohort achieved long-term (1 year) remission. In 'real life studies', the outcome was somewhat better, probably due to proper selection of patients and open, mostly retrospective study designs. A clear benefit of biologicals is apparent in otherwise treatment refractory patients, in extraintestinal manifestations and in Crohn´s disease (CD) with fistulizing complications. Biologicals achieve mucosal healing (MH) more often than corticosteroids or thiopurines, and MH is associated with improved prognosis. However, this does not justify escalating treatment until MH is reached since controlled trials proving this point of 'treat to target' are lacking both in ulcerative colitis and CD. Surgical rates have decreased with increasing use of biologicals, but disease progression has not been proven to improve. With the exception of opportunistic infections, serious adverse events are rare. In conclusion, biologicals have changed the scene considerably and expanded our armamentarium, but there is also a marketing hype fostering expectations without evidence.

Full, Partial, and Modified Permutations of the Mayo Score: Characterizing Clinical and Patient-Reported Outcomes in Ulcerative Colitis Patients

Background

Understanding ulcerative colitis disease activity assessed via the full, modified, or partial Mayo Score may help clinicians apply results from clinical trials to practice and facilitate interpretation of recent and older studies.

Methods

Mayo Score variables were assessed in a cross-sectional study of 2608 ulcerative colitis patients.

Results

Permutations of Mayo Scores were highly correlated, and models predicting the omitted variable from each permutation demonstrated significant agreement between predicted and observed values.

Conclusions

Partial/modified Mayo Scores may be used to predict endoscopic and Physician's Global Assessment scores, and serve as proxies for the full Mayo Score in clinical practice/trials.

The Reality of Patient-Reported Outcomes of Health-Related Quality of Life in an Italian Cohort of Patients with Inflammatory Bowel Disease: Results from a Cross-Sectional Study

Inflammatory bowel disease (IBD) has a negative impact on patients’ physical and psychological well-being, social performance, and working capacity, thereby worsening their health-related quality of life (HRQoL). Clinicians should take care of the patients’ global health, including the psychological, social, and emotional spheres. We aimed to investigate the reality of patient-reported outcomes of HRQoL in a series of IBD patients. Consecutive Crohn´s disease (CD) and ulcerative colitis (UC) patients in clinical remission were recruited. The survey consisted of the Short Inflammatory Bowel Disease Questionnaire (S-IBDQ), the Hospital Anxiety and Depression Scale (HADS), the Brief Illness Perception Questionnaire (B-IPQ), and a questionnaire dealing with impact of IBD on patients’ lives. Demographic and clinical characteristics were recorded. Of 202 participants (29% CD and 71% UC; 54% male; median age 48 years; mean disease duration 14 ± 11 years), 52% had poor HRQoL, 45% anxiety/depression, and 35% sleep disturbance and a high perception of disease (mean score 42.8 ± 14.3). In the multivariate analysis, a low HRQoL was rather associated with UC than CD (p = 0.037), IBD surgery (p = 0.010), disease duration (p = 0.01), sleep disturbance (p = 0.014), anxiety/depression (p = 0.042), and high illness perception (p = 0.006). IBD affected working performance and social activities in 62% and 74% of patients, respectively. Satisfaction regarding quality of care, biologics, and surgery approach were claimed in 73%, 69%, and 76% of patients, respectively. Although 84% of patients trusted their gastroenterologist, only 66% of them discussed IBD impact on HRQoL during visit. In a series of IBD patients in remission, the low HRQoL was significantly associated with surgery, disease duration, sleep disturbance, anxiety/depression, and high illness perception. Even though patients were satisfied with the quality of their care, it appears that clinicians should pay more attention to patients’ emotional status.
