RESUMO

BACKGROUND: Despite advances in human immunodeficiency virus (HIV) prevention methods, such as the advent of pre-exposure prophylaxis (PrEP), the number of people with newly acquired HIV remains high, particularly in at-risk groups. A prophylactic HIV vaccine could contribute to reduced disease prevalence and future transmission and address limitations of existing options, such as suboptimal long-term adherence to PrEPs. METHODS: This qualitative study aimed to capture perceptions towards and acceptance of prophylactic HIV vaccination in three adult populations in the United States: the general population, 'at-risk' individuals (e.g. men who have sex with men, transgender individuals, gender-nonconforming individuals, and individuals in a sexual relationship with a person living with HIV), and parents/caregivers of children aged 9-17 years. Interviews were conducted with 55 participants to explore key drivers and barriers to HIV vaccine uptake, and a conceptual model was developed. RESULTS: The sample was diverse; participants were 51% female, aged 20-57 years (mean 37 years), 33% with high school diploma as highest education level, and identified as White (42%), Black or African American (35%), of Hispanic, Latino, or Spanish origin (22%), or other races/ethnicities (8%) [groupings are not mutually exclusive]. Perceptions were influenced by individual, interpersonal, community, institutional, and structural factors. Overall, 98% of participants thought vaccination would be beneficial in preventing HIV. Key considerations/barriers included perceived susceptibility, i.e. whether participants felt there was a risk of contracting HIV (discussed by 90%); the clinical profile of the vaccine (e.g. the adverse effect profile [98%], and vaccine efficacy [85%], cost [73%] and administration schedule [88%]); and concerns around potential vaccine-induced seropositivity (VISP; 62%). Stigma was not found to be an important barrier, with a general view that vaccination status was personal. Participants in the 'at-risk' group were the most likely to accept an HIV vaccine (70%). Unique concerns in the subgroups included how a potential vaccine's clinical profile compared with PrEP, voiced by those receiving/considering PrEP, and considerations of children's views on the topic, voiced by parents/caregivers. CONCLUSIONS: Understanding these factors could help develop HIV vaccine research strategies and contribute toward public health messaging to support future HIV vaccination programs.

RESUMO

BACKGROUND: There is increased emphasis on incorporating patient perspectives and patient-relevant endpoints in drug development. We developed a conceptual model of the impact of chronic hepatitis B (CHB) on patients' lives and evaluated the content validity of the Hepatitis B Quality of Life (HBQOL) instrument, a patient-reported outcome tool for use in clinical studies, as a patient-relevant endpoint to measure health-related quality of life in patients with CHB. METHODS: A literature review of qualitative studies of patient experience with CHB and concept elicitation telephone interviews with patients with CHB in the United Kingdom were used to develop a conceptual model of the experience and impact of living with CHB. The content validity of the HBQOL was evaluated using cognitive debriefing techniques. RESULTS: The qualitative literature review (N = 43 publications) showed that patients with CHB experience emotional/psychological impacts. During concept elicitation interviews (N = 24), fatigue was the most commonly reported symptom, and most participants were worried/anxious about virus transmission and disease progression/death. A conceptual model of patients' experiences with CHB was developed. The conceptual relevance and comprehensibility of the HBQOL were supported, though limitations, including the lack of a self-stigma item and recall period, were noted for future improvement. CONCLUSIONS: The conceptual model shows that patients with CHB experience emotional/psychological impacts that affect their lifestyles, relationships, and work/schooling. The cognitive debriefing interviews support the content validity of the HBQOL as a conceptually relevant patient-reported outcome measure of health-related quality of life.

RESUMO

BACKGROUND: People with chronic hepatitis B (CHB) commonly experience social and self-stigma. This study sought to understand the impacts of CHB-related stigma and a functional cure on stigma. METHODS: Adults with CHB with a wide range of age and education were recruited from 5 countries and participated in 90-minute qualitative, semi-structured interviews to explore concepts related to CHB-associated stigma and its impact. Participants answered open-ended concept-elicitation questions regarding their experience of social and self-stigma, and the potential impact of reduced CHB-related stigma. RESULTS: Sixty-three participants aged 25 to 71 years (15 from the United States and 12 each from China, Germany, Italy, and Japan) reported emotional, lifestyle, and social impacts of living with CHB, including prejudice, marginalization, and negative relationship and work experiences. Self-stigma led to low self-esteem, concealment of CHB status, and social withdrawal. Most participants stated a functional cure for hepatitis B would reduce self-stigma. CONCLUSIONS: CHB-related social and self-stigma are widely prevalent and affect many aspects of life. A functional cure for hepatitis B may reduce social and self-stigma and substantially improve the health-related quality of life of people with CHB. Incorporating stigma into guidelines along with infectivity considerations may broaden the patient groups who should receive treatment.

RESUMO

INTRODUCTION: We studied the effect of intravenous (IV)-golimumab on fatigue and the association of fatigue improvement with clinical response post hoc in adults with active ankylosing spondylitis (AS) in the GO-ALIVE trial. METHODS: Patients were randomized to IV-golimumab 2 mg/kg (N = 105) at week (W) 0, W4, then every 8 W (Q8W) or placebo (N = 103) at W0, W4, W12, crossover to IV-golimumab 2 mg/kg at W16, W20, then Q8W through W52. Fatigue measures included Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) Question #1 (fatigue; 0 [none], 10 [worst]; decrease indicates improvement) and 36-Item Short Form Health Survey (SF-36) vitality subscale (0 [worst], 100 [best]; increase indicates improvement). Minimum clinically important difference is ≥ 1 for BASDAI-fatigue and ≥ 5 for SF-36 vitality. GO-ALIVE primary endpoint was Assessment of SpondyloArthritis international Society ≥ 20% improvement criteria (ASAS20). Other clinical outcomes assessed included other ASAS responses, Ankylosing Spondylitis Disease Activity Score, and Bath Ankylosing Spondylitis Functional Index score. The distribution-based minimally important differences (MIDs) were determined for BASDAI-fatigue and SF-36 vitality. The relationship between improvement in fatigue and clinical outcomes was assessed via multivariable logistic regression. RESULTS: Mean changes in BASDAI-fatigue/SF-36 vitality scores were greater with IV-golimumab versus placebo at W16 (- 2.74/8.46 versus - 0.73/2.08, both nominal p ≤ 0.003); by W52 (after crossover), differences between groups narrowed (- 3.18/9.39 versus - 3.07/9.17). BASDAI-fatigue/SF-36 vitality MIDs were achieved by greater proportions of IV-golimumab-treated versus placebo-treated patients at W16 (75.2%/71.4% versus 42.7%/35.0%). A one-point/five-point improvement in BASDAI-fatigue/SF-36 vitality scores at W16 increased likelihood of achieving ASAS20 (odds ratios [95% confidence intervals]: 3.15 [2.21, 4.50] and 2.10 [1.62, 2.71], respectively) and ASAS40 (3.04 [2.15, 4.28] and 2.24 [1.68, 3.00], respectively) responses at W16; concurrent improvements and clinical response at W52 were consistent. A one-point/five-point improvement in BASDAI-fatigue/SF-36 vitality scores at W16 predicted increased likelihood of achieving ASAS20 (1.62 [1.35, 1.95] and 1.52 [1.25, 1.86], respectively) and ASAS40 (1.62 [1.37, 1.92] and 1.44 [1.20, 1.73], respectively) responses at W52. CONCLUSIONS: IV-golimumab provided important and sustained fatigue improvement in patients with AS that positively associated with achieving clinical response. TRIAL REGISTRATION: ClinicalTrials.gov identifier, NCT02186873.


Ankylosing spondylitis (AS) is a type of arthritis that mostly affects the spine. Patients with AS also often have severe fatigue. Intravenous (IV)-golimumab, which blocks the inflammatory action of tumor necrosis factor, is approved to treat AS. We used information from a clinical trial (GO-ALIVE) to determine whether IV-golimumab reduced fatigue in patients with AS, and if fatigue improvement was associated with improvement in other AS symptoms, including spinal pain, ability to function, and inflammation. In the 1-year GO-ALIVE study, patients were assigned to receive either IV-golimumab or placebo. Patients assigned to placebo were switched to IV-golimumab starting at week 16. The Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) fatigue question and the 36-Item Short Form Health Survey (SF-36) vitality subscale were used to assess fatigue. Improvement in AS symptoms was measured using the Assessment of SpondyloArthritis international Society ≥ 20% and ≥ 40%  improvement criteria (ASAS20 and ASAS40). After 16 weeks of treatment, patients treated with IV-golimumab, on average, had statistically significantly greater improvement in both measures of fatigue than patients treated with placebo. At 1 year, after the placebo group had received IV-golimumab starting at week 16, improvement in fatigue was similar between groups. Improvement in fatigue at week 16 increased the likelihood that ASAS20 and ASAS40 would be achieved at week 16. Similar results were observed at 1 year. Additionally, improvement in fatigue at week 16 predicted the likelihood of achieving ASAS20 and ASAS40 at 1 year. Together, these results demonstrate that IV-golimumab provided important, long-term improvement in fatigue in patients with AS that was positively associated with improvement in AS symptoms.

RESUMO

BACKGROUND: The Respiratory Infection Intensity and Impact Questionnaire (RiiQ™) is a patient-reported outcome measure designed to assess symptoms and impacts of respiratory syncytial virus (RSV) infection. This study evaluated the construct validity, reliability, and responsiveness of the RiiQ™ Respiratory and Systemic Symptoms Scale scores. METHODS: Prospective data were analyzed from a total of 1795 participants, including from non-hospitalized patients with acute respiratory infection (ARI) and no coinfections enrolled in a Phase 2b RSV vaccine study (RSV-positive: n = 60; RSV-negative: n = 1615), and two observational studies of patients hospitalized with RSV (n = 20; n = 100). Descriptive statistics, confirmatory factor analysis (CFA), test-retest intraclass correlation coefficients (ICCs), construct validity correlations (between a clinician-assessed clinical questionnaire and the RiiQ™ symptoms scale), known-groups validity, and responsiveness (correlations of change scores) were evaluated. RESULTS: Mean patient age ranged from 66.5 to 71.5 years and the majority of patients were female. Initial assessments in the vaccine trial (ARI Day 1) were suggestive of less severe illness than in the observational studies with hospitalized patients. CFA loadings (> 0.40) supported summary scores. ICCs exceeding the recommended threshold of 0.70 supported test-retest reliability for Respiratory and Systemic Symptoms, except in the small observational study. At the scale level, correlations were moderate to strong (|r| ≥ 0.3) and positive between the Respiratory Symptoms Scale and the related clinical questionnaire scores, reflecting measurement of similar symptoms in support of convergent validity. Correlations with change in Patient Global Impression of Severity > 0.30 supported responsiveness. CONCLUSIONS: Psychometric tests applied to the RiiQ™ Symptoms scales provide evidence of its reliability, construct validity, discriminating ability, and responsiveness for use in clinical studies to assess the onset and severity of RSV symptoms.

RESUMO

BACKGROUND: The Symptoms of Infection with Coronavirus-19 (SIC) is a 30-item patient-reported outcome (PRO) measure scored by body system composites to assess signs/symptoms of coronavirus disease 2019 (COVID-19). In addition to cross-sectional and longitudinal psychometric evaluations, qualitative exit interviews were conducted to support the content validity of the SIC. METHODS: In a cross-sectional study, adults diagnosed with COVID-19 in the United States completed the web-based SIC and additional PRO measures. A subset was invited to participate in phone-based exit interviews. Longitudinal psychometric properties were assessed in ENSEMBLE2, a multinational, randomized, double-blind, placebo-controlled, phase 3 trial of the Ad26.COV2.S COVID-19 vaccine. Psychometric properties evaluated included structure, scoring, reliability, construct validity, discriminating ability, responsiveness, and meaningful change thresholds of SIC items and composite scores. RESULTS: In the cross-sectional study, 152 participants completed the SIC (mean age, 51.0 ± 18.6 years) and 20 completed follow-up interviews. Fatigue (77.6%), feeling unwell (65.8%), and cough (60.5%) were symptoms most frequently reported. SIC inter-item correlations were all positive and mostly moderate (r ≥ 0.3) and statistically significant. SIC items and Patient-Reported Outcomes Measurement Information System-29 (PROMIS-29) scores correlated as hypothesized (all r ≥ 0.32). Internal consistency reliabilities of all SIC composite scores were satisfactory (Cronbach's alpha, 0.69-0.91). SIC composite scores correlated moderately (r = 0.30-0.49) to strongly (r ≥ 0.50) with PROMIS-29 scores and Patient Global Impression of Severity (PGIS) ratings (all P < 0.01). A variety of signs/symptoms were cited in exit interviews, and participants considered the SIC straightforward, comprehensive, and easy to use. From ENSEMBLE2, 183 participants with laboratory-confirmed moderate to severe/critical COVID-19 were included (51.5 ± 14.8 years). Strong test-retest reliabilities were observed for most SIC composite scores (intraclass correlations ≥ 0.60). Statistically significant differences across PGIS severity levels were found for all but 1 composite score, supporting known-groups validity. All SIC composite scores demonstrated responsiveness based on changes in PGIS. CONCLUSIONS: The psychometric evaluations provided strong evidence for the reliability and validity of the SIC for measuring COVID-19 symptoms, supporting its use in vaccine and treatment trials. In exit interviews, participants described a broad range of signs/symptoms consistent with previous research, further supporting the content validity and format of the SIC.


Coronavirus disease 2019 (COVID-19) is a serious disease that continues to evolve globally. Researchers developed the Symptoms of Infection with Coronavirus-19 (SIC), a 30-item questionnaire designed for patients to report signs and symptoms of COVID-19. In this study, the researchers formally analyzed how well the SIC measures the patient experience with COVID-19, using survey and clinical trial data as well as telephone interviews. Adults with COVID-19 and at least 2 bothersome symptoms completed the web-based survey, and some of these individuals also participated in in-depth interviews. Participants in a clinical trial for a COVID-19 vaccine also completed the SIC measure. The SIC was compared with other commonly used questionnaires that evaluate patient experience. The most commonly reported symptoms of COVID-19 were fatigue, feeling unwell, cough, weakness, and headache. The items for individual symptoms (e.g., "cough") and combined scores for body systems (e.g., "respiratory system") performed well in statistical analyses. Participants found the SIC to be straightforward, comprehensive, and easy to use. The SIC may prove useful in the future for vaccine and treatment trials for COVID-19.

RESUMO

BACKGROUND: Respiratory syncytial virus (RSV) can cause serious lower respiratory tract disease in older adults, but no licensed RSV vaccine currently exists. An adenovirus serotype 26 RSV vector encoding a prefusion F (preF) protein (Ad26.RSV.preF) in combination with RSV preF protein was previously shown to elicit humoral and cellular immunogenicity. METHODS: We conducted a randomized, double-blind, placebo-controlled, phase 2b, proof-of-concept trial to evaluate the efficacy, immunogenicity, and safety of an Ad26.RSV.preF-RSV preF protein vaccine. Adults who were 65 years of age or older were randomly assigned in a 1:1 ratio to receive vaccine or placebo. The primary end point was the first occurrence of RSV-mediated lower respiratory tract disease that met one of three case definitions: three or more symptoms of lower respiratory tract infection (definition 1), two or more symptoms of lower respiratory tract infection (definition 2), and either two or more symptoms of lower respiratory tract infection or one or more symptoms of lower respiratory tract infection plus at least one systemic symptom (definition 3). RESULTS: Overall, 5782 participants were enrolled and received an injection. RSV-mediated lower respiratory tract disease meeting case definitions 1, 2, and 3 occurred in 6, 10, and 13 vaccine recipients and in 30, 40, and 43 placebo recipients, respectively. Vaccine efficacy was 80.0% (94.2% confidence interval [CI], 52.2 to 92.9), 75.0% (94.2% CI, 50.1 to 88.5), and 69.8% (94.2% CI, 43.7 to 84.7) for case definitions 1, 2, and 3, respectively. After vaccination, RSV A2 neutralizing antibody titers increased by a factor of 12.1 from baseline to day 15, a finding consistent with other immunogenicity measures. Percentages of participants with solicited local and systemic adverse events were higher in the vaccine group than in the placebo group (local, 37.9% vs. 8.4%; systemic, 41.4% vs. 16.4%); most adverse events were mild to moderate in severity. The frequency of serious adverse events was similar in the vaccine group and the placebo group (4.6% and 4.7%, respectively). CONCLUSIONS: In adults 65 years of age or older, Ad26.RSV.preF-RSV preF protein vaccine was immunogenic and prevented RSV-mediated lower respiratory tract disease.

RESUMO

BACKGROUND: The Symptoms of Infection with Coronavirus-19 (SIC) is a 30-item patient-reported outcome measure to evaluate the presence and severity of COVID-19 signs/symptoms in adults. This study expanded the context of use of the adult SIC among adolescents aged 12-17 years and supported a pediatric adaptation (the Pediatric SIC [PedSIC]) for caregiver assessment of signs/symptoms in children aged < 12 years. METHODS: Draft versions of the PedSIC and reference materials containing sign/symptom definitions for adolescents, based on an assessment of the reading level of SIC items by a professional linguist, were developed to facilitate accurate completion of the SIC by adolescents and observer-report (PedSIC) by caregivers. For adolescents, reference materials were intended to provide definitions for selected signs/symptoms identified to have a higher reading level. Iterative rounds of cognitive debriefing interviews were conducted from November 2020 to January 2021 to evaluate adolescent understanding of the SIC reference materials and inform refinement of the PedSIC for caregivers of children too young to reliably self-report. Participants were identified via databases of individuals who previously expressed interest in participating in qualitative research and were then screened for eligibility. Recruitment quotas were established to improve sample diversity. Thematic analysis and descriptive statistics were used to assess qualitative and demographic data, respectively. RESULTS: Nine healthy adolescents (mean [SD, range] age, 14 [1.76, 12-17] years, 56% female, 22% non-White; round 1, n = 6; round 2, n = 3) and 17 caregivers (mean [SD, range] age, 34 [6.28, 26-41] years, 59% female, 35% non-White; round 1, n = 9; round 2, n = 8) were interviewed. Adolescents understood the majority of signs/symptoms (22 of the 30 SIC items) without assistance or use of the reference materials during the cognitive debriefing interview. Definitions were added to the reference materials for 5 additional items, and clarifications provided to existing definitions for 3 items. Seven observer-report (PedSIC) items were modified following feedback from caregivers of healthy young children. Reference materials (similar to those for adolescent use) were developed to support caregiver understanding of the intent of the PedSIC items collecting input from children ages ≥ 5- < 12 years. CONCLUSIONS: Results support using the SIC, PedSIC, and their associated reference materials to evaluate the presence and severity of COVID-19 signs/symptoms in adolescents and children aged < 12 years via caregiver-supported report, respectively.

RESUMO

BACKGROUND: Hepatitis B surface antigen (HBsAg) loss is associated with improved clinical outcomes for individuals with chronic hepatitis B (CHB); however, the effects of varying HBsAg levels on clinical outcomes in diverse cohorts are understudied. METHODS: In this cross-sectional, multicentre, retrospective study, the data on adult subjects enrolled in the Canadian HBV Network with CHB seen from 1 January 2012 to 30 January 2021 with the treatment and virologic data within 1 year of HBsAg testing were analyzed. Patients were tested for HBsAg using qualitative (for HBsAg-negative samples) and/or commercial quantitative assays. Fibrosis or hepatic necroinflammation was determined by the liver stiffness measurement (LSM). The baseline data were summarized using descriptive statistics and compared by using univariable/multivariable analyses. RESULTS: This study included 844 CHB patients, with a median age of 49.6 years (IQR 40.1-60.5), and 37% were female. In total, 751 patients (78.6%) had known ethnicity data, and 76.7% self-reported as Asian, 11.4% as Black, 6.8% as White, and 4.8% as other. Among the 844 patients, 237 (28.0%) were HBsAg (-) (1000 IU/mL. Overall, 80% (682) had known HBeAg status at the last follow-up, and the majority (87.0%) were HBeAg-negative. In addition, 54% (461/844) had prior antiviral therapy, 19.7% of which (16.3, 23.7, n = 91) were HBsAg (-). The treated patients had a lower risk of cirrhosis (16.46, 95% CI 1.89-143.39, p = 0.01) or HCC (8.23, 95% CI 1.01-67.39, p = 0.05) than the untreated patients. A lower proportion of the HBsAg-loss group had cirrhosis (5.7% vs. 10.9%, p = 0.021) and HCC (0.9% vs. 6.2%, p = 0.001). CONCLUSION: In this retrospective, ethnically diverse cohort study, CHB patients who received antiviral therapy and/or had HBsAg loss were less likely to develop cirrhosis and HCC, confirming the results of the studies in less diverse cohorts. No association was found between the qHBsAg level and fibrosis determined with LSM. Individuals who achieved HBsAg loss had low-level qHBsAg within 1 year of seroclearance.

RESUMO

BACKGROUND: Given the urgent need for vaccines and treatments for coronavirus disease 2019 (COVID-19), the Symptoms of Infection with Coronavirus-19 (SIC), a comprehensive, patient-reported outcome (PRO) measure of signs and symptoms associated with COVID-19, was developed in full alignment with current US regulatory guidance to support evaluations of vaccines and treatments in development. METHODS: An initial version of the SIC was developed to address concepts identified through a targeted literature review and consultation with experts in infectious diseases and clinicians routinely managing COVID-19 in a hospital setting. A qualitative study was conducted in sites in the United States among 31 participants aged ≥ 18 years who were English-speaking and willing and able to provide informed consent and a self-reported history by telephone or online method. The measure was refined based on additional feedback from the clinicians and three iterative rounds of combined concept elicitation and cognitive debriefing interviews conducted with patients, caregivers, and healthy volunteers. RESULTS: Among 39 scientific articles identified in the literature review, 35 COVID-19 signs and symptoms were reported and confirmed during interviews with clinicians, patients, and caregivers. Patients and healthy participants suggested changes for refining the draft SIC to ensure consistent interpretation and endorsed both the 24-h recall period and use of an 11-point numeric rating scale (NRS) for capturing change in symptom severity. The final version of the SIC captures the daily presence or absence of 30 symptoms and a rating of severity for 25 of the 30 symptoms using an NRS for those symptoms reported as present. CONCLUSIONS: The SIC comprehensively addresses observations described in the literature, by clinicians, and by patients, and captures patients' experiences with COVID-19 in a manner that minimizes complexity and facilitates completion for both patients and healthy volunteers. This measure is thus appropriate for use in clinical trials of both therapeutics and vaccines for COVID-19.

RESUMO

INTRODUCTION/OBJECTIVES: To evaluate changes in health-related quality of life (HRQoL) and productivity following treatment with intravenous (IV) golimumab in patients with psoriatic arthritis (PsA). METHODS: Patients were randomized to IV golimumab 2 mg/kg (n=241) at Weeks 0, 4, then every 8 weeks (q8w) through Week 52 or placebo (n=239) at Weeks 0, 4, then q8w, with crossover to IV golimumab 2 mg/kg at Weeks 24, 28, then q8w through Week 52. Change from baseline in EuroQol-5 dimension-5 level (EQ-5D-5L) index and visual analog scale (EQ-VAS), daily productivity VAS, and the Work Limitations Questionnaire (WLQ) was assessed. Relationships between these outcomes and disease activity and patient functional capability were evaluated post hoc. RESULTS: At Week 8, change from baseline in EQ-5D-5L index (0.14 vs 0.04), EQ-VAS (17.16 vs 3.69), daily productivity VAS (-2.91 vs -0.71), and WLQ productivity loss score (-2.92 vs -0.78) was greater in the golimumab group versus the placebo group, respectively. At Week 52, change from baseline was similar in the golimumab and placebo-crossover groups (EQ-5D-5L index: 0.17 and 0.15; EQ-VAS: 21.61 and 20.84; daily productivity VAS: -2.89 and -3.31; WLQ productivity loss: -4.49 and -3.28, respectively). HRQoL and productivity were generally associated with disease activity and functional capability, with continued association from Week 8 through Week 52. CONCLUSION: IV golimumab resulted in early and sustained improvements in HRQoL and productivity from Week 8 through 1 year in patients with PsA. HRQoL and productivity improvements were associated with improvements in disease activity and patient functional capability. Key Points • In patients with active psoriatic arthritis (PsA), intravenous (IV) golimumab improved health-related quality of life (HRQoL) and productivity as early as 8 weeks and maintained improvement through 1 year • Improvements in HRQoL and productivity outcomes in patients with PsA treated with IV golimumab were associated with improvements in disease activity and patient functional capability outcomes • IV golimumab is an effective treatment option for PsA that can mitigate the negative effects of the disease on HRQoL and productivity.

RESUMO

INTRODUCTION/OBJECTIVES: The effect of intravenous (IV) golimumab on health-related quality of life (HRQoL) and productivity in patients with ankylosing spondylitis (AS) was evaluated. METHOD: Patients were randomized to IV golimumab 2 mg/kg (n = 105) at weeks 0, 4, then every 8 weeks (q8w) through week 52 or placebo (n = 103) at weeks 0, 4, 12, with crossover to golimumab 2 mg/kg at weeks 16, 20, then q8w through week 52. Changes from baseline in EuroQol-5 dimension-5 level (EQ-5D-5L) index and visual analog scale (EQ-VAS), daily productivity VAS, Work Limitations Questionnaire (WLQ), and Ankylosing Spondylitis Quality of Life (ASQoL) were assessed. Correlations between these outcomes and disease activity and patient functioning outcomes were evaluated post hoc. RESULTS: At week 16, changes from baseline (mean ± standard deviation) in EQ-5D-5L index (0.17 ± 0.16 vs 0.05 ± 0.14), EQ-VAS (20.3 ± 24.6 vs 4.8 ± 23.5), daily productivity VAS (- 2.9 ± - 2.9 vs - 1.1 ± - 2.5), WLQ productivity loss score (- 3.5 ± - 5.3 vs - 1.9 ± - 4.0), and ASQoL (- 5.4 ± - 5.0 vs - 1.8 ± - 4.5) were greater in the IV golimumab versus placebo group, respectively. At week 28, changes from baseline were similar between the IV golimumab and placebo-crossover groups (EQ-5D-5L index: 0.18 ± 0.17 and 0.16 ± 0.16, EQ-VAS: 20.5 ± 27.9 and 22.5 ± 23.1, daily productivity VAS: - 3.1 ± - 3.0 and - 3.1 ± - 2.8, WLQ productivity loss: - 3.9 ± - 5.5 and - 4.5 ± - 4.5, and ASQoL: - 5.3 ± - 5.2 and - 5.3 ± - 4.8, respectively); improvements were maintained through week 52. HRQoL and productivity outcomes were generally moderately correlated with disease activity and functioning outcomes. CONCLUSIONS: In patients with AS, IV golimumab produced sustained improvements in HRQoL and productivity through 1 year, which correlated with improvements in disease activity and functioning. ClinicalTrials.gov registry number is NCT02186873. Key Points • Intravenous (IV) golimumab resulted in clinically important improvement in general and ankylosing spondylitis-specific health-related quality of life (HRQoL) and productivity outcomes in patients with ankylosing spondylitis (AS) as early as week 8 and maintained improvement through 1 year • Improvements in HRQoL and productivity outcomes in these patients with AS were correlated with improvements in measures of disease activity and patient functional capability • IV golimumab is an effective treatment option for AS that can help mitigate the negative effects of the disease on HRQoL and productivity.

RESUMO

BACKGROUND AND PURPOSE: A palliative approach involves adapting and integrating palliative care knowledge and expertise earlier on and across sectors of care for people who have life-limiting chronic conditions. This study explored the extent to which nurses' and care aides' self-perceived palliative care competence may explain variation in the application of a palliative approach across nursing care settings that do not specialize in palliative care. A secondary objective was to psychometrically evaluate an instrument for measuring self-perceived palliative care competence.Methods and procedures: Data were collected via a cross-sectional survey (N = 1468) of registered nurses, licensed practical nurses, and care aides at 114 randomly selected hospital-based medical units, home care offices, and residential care facilities. The questionnaire included the Palliative Care Nursing Self-Competence Scale. Multilevel logistic regression and multigroup confirmatory factor analyses were conducted. RESULTS: In addition to self-perceived competence, factors associated with a palliative approach include identification of patients who have life-limiting conditions and who would benefit from a palliative approach, and work environment. The psychometric analyses of the Palliative Care Nursing Self-Competence Scale confirmed a 10-dimensional structure, strong internal consistency reliability, and measurement equivalence.Discussion and conclusion: This study provides information for future development and research on interventions for integrating a palliative approach.

RESUMO

OBJECTIVE: Evaluate the effect of intravenous golimumab on health-related quality of life (HRQoL) in patients with ankylosing spondylitis (AS) through week 28 of the phase III, multicenter, randomized, double-blind, placebo-controlled GO-ALIVE study. METHODS: Adult patients (n = 208) were randomized to IV golimumab 2 mg/kg (n = 105) at weeks 0, 4, and 12 and every 8 weeks or placebo (n = 103) at weeks 0, 4, and 12, with crossover to golimumab 2mg/kg at weeks 16, 20, and every 8 weeks. General HRQoL was evaluated using the Short Form Health Survey (SF-36) Physical Component Summary/Mental Component Summary (PCS/MCS), and the EQ VAS, and AS disease-specific HRQoL was assessed using the Ankylosing Spondylitis Quality of Life (ASQoL) instrument. RESULTS: Mean improvements from baseline in SF-36 PCS were greater in the golimumab group versus the placebo group at weeks 8 and 16 (6.8 vs 2.1 and 8.5 vs 2.9, respectively; P < .001); similar results were observed for SF-36 MCS (5.6 vs 1.7 and 6.5 vs 0.8, respectively; P < .001). Mean improvement in each of 8 subscale scores of the SF-36 were also greater for golimumab-treated patients versus placebo at weeks 8 and 16. Mean improvements in EQ VAS and ASQoL were greater in the golimumab group versus placebo at week 8 and week 16. Greater proportions of golimumab-treated patients had clinically meaningful improvement in SF-36 PCS, SF-36 MCS, EQ VAS, and ASQoL at weeks 8 and 16; improvements in SF-36 PCS/MCS, EQ VAS, and ASQoL were maintained through week 28. CONCLUSIONS: Golimumab-treated patients had greater mean improvements in HRQoL measures compared with placebo through week 16. Clinically meaningful improvements were observed as early as week 8 and continued through week 28.

RESUMO

OBJECTIVES: Evaluate the effects of intravenous golimumab 2 mg/kg on multiple domains of health-related quality of life (HRQoL) in adult patients with active psoriatic arthritis (PsA). METHODS: In this phase III, randomized, double-blinded, placebo-controlled study, adults with active PsA were randomized in a 1:1 ratio to receive intravenous (IV) infusions of placebo (n = 239) or golimumab 2 mg/kg (n = 241) at weeks 0, 4, 12, and 20. Physical function was assessed using the Health Assessment Questionnaire-Disability Index (HAQ-DI). HRQoL was assessed using the 36-item Short-Form Health Survey Physical and Mental Component Summary (SF-36 PCS/MCS) scores, the Functional Assessment of Chronic Illness Therapy (FACIT)-Fatigue, EQ VAS, and the Dermatology Life Quality Index (DLQI). RESULTS: Patients in the golimumab group had greater mean changes from baseline in HAQ-DI compared with placebo at weeks 8 (-0.52 vs -0.10), 14 (-0.60 vs -0.12), and 24 (-0.63 vs -0.14). Mean improvements from baseline in SF-36 PCS (8.0 vs 1.7), SF-36 MCS (5.0 vs 1.2), EQ VAS (17.2 vs 3.7), FACIT-Fatigue (7.9 vs 2.0), and DLQI (-7.2 vs -1.7) were also greater in the golimumab group versus placebo at week 8 and were maintained or increased through week 24. Greater proportions of golimumab-treated patients had improvements greater than or equal to the minimal clinically important difference (MCID) for HAQ-DI, SF-36 PCS/MCS, EQ VAS, FACIT-Fatigue, and DLQI scores at weeks 14 and 24. CONCLUSION: Improvements in HRQoL were greater in the IV golimumab group compared with placebo and were evident at week 8 and sustained through week 24.

RESUMO

BACKGROUND: People with chronic infectious diseases such as hepatitis B can face stigma, which can influence everyday life as well as willingness to engage with medical professionals or disclose disease status. A systematic literature review was performed to characterize the level and type of stigma experienced by people infected with hepatitis B virus (HBV) as well as to identify instruments used to measure it. METHODS: A literature review was performed using the PubMed, Embase and Cochrane Library databases to identify studies describing HBV-related stigma. For inclusion, articles were required to be published in full-text form, in English and report quantitative or qualitative data on HBV-related stigma that could be extracted. RESULTS: A total of 23 (17 quantitative and 6 qualitative) articles examined HBV-related stigma. The scope of the review was global but nearly all identified studies were conducted in countries in the WHO Southeast Asia or Western Pacific regions or within immigrant communities in North America. Several quantitative studies utilized tools specifically designed to assess aspects of stigma. Qualitative studies were primarily conducted via patient interviews. Internalized and social stigma were common among people living with chronic HBV . Some people also perceived structural/institutional stigma, with up to 20% believing that they may be denied healthcare and up to 30% stating they may experience workplace discrimination due to HBV. CONCLUSION: HBV-related stigma is common, particularly in some countries in Southeast Asia and the Western Pacific region and among Asian immigrant communities, but is poorly characterized in non-Asian populations. Initiatives are needed to document and combat stigma (particularly in settings/jurisdictions where it is poorly described) as well as its clinical and socioeconomic consequences.

RESUMO

PURPOSE: The use of patient-reported outcome (PRO) measures in clinical practice is increasing. Following the creation of a 'User's Guide to Implementing PRO Assessment in Clinical Practice' by the International Society for Quality of Life Research (ISOQOL), volunteers from ISOQOL sought to create a Companion Guide to assist health care providers with the scientific and practical considerations involved in implementing and using PRO measures in clinical care by using information from real-world case studies. This paper summarizes the key issues presented in the Companion Guide. METHODS: Ten respondents, who were members of the ISOQOL's CP-SIG and worked in various clinical areas, participated in a survey or telephone interview. Participants were from Canada (n = 2), Denmark (n = 1), England (n = 2), Holland (n = 1), and the United States (n = 4). RESULTS: Based on the information provided by respondents, a Companion Guide was produced, organized according to the nine questions presented in the User's Guide. An additional section for key take-home messages was also provided. This guide provides examples of issues and considerations related to the implementation of PRO measures in clinical practice. CONCLUSIONS: Respondents provided insight into their experiences and emphasized that PRO initiatives were likely to be more successful if there is purposeful, designed integration into clinical practice, meaningful substantive engagement with all stakeholders and access to necessary organizational resources. The ability to leverage existing technology as well as realistic and stakeholder consensus-driven expectations for planning and timing were also key to the successful implementation of PRO measures.

RESUMO

Health-related quality of life (HRQoL) is an important endpoint, especially in clinical trials for malignancies with a long course of disease, such as chronic lymphocytic leukemia (CLL). Patient-reported outcomes were examined in the randomized, double-blind, placebo-controlled HELIOS study to assess the impact of treatment with the Bruton's tyrosine kinase inhibitor ibrutinib, added to bendamustine plus rituximab (BR) background therapy. Measures included FACIT-Fatigue, EORTC QLQ-C30, QLQ-CLL16, and EQ-5D-5L. Of 578 patients enrolled, 540 (93%) provided FACIT-Fatigue responses at baseline. Most had only a moderate degree of impairment at baseline; mean values did not appear to change over time in either treatment arm, suggesting that adding ibrutinib to BR did not impact health-related quality of life. However, post-hoc analyses showed that subgroups of patients with the worst fatigue, physical functional status, and well-being at baseline had greater improvements in these outcomes with ibrutinib plus BR treatment versus placebo.

RESUMO

BACKGROUND: Obtaining the patient's view about the outcome of care is an essential component of patient-centered care. Many patient-reported outcome (PRO) instruments for different purposes have been developed since the 1960s. Measurement validation is fundamental in the development, evaluation, and use of PRO instruments. OBJECTIVES: This paper provides a review of modern perspectives of measurement validation in relation to the followings three questions as applied to PROs: (1) What evidence is needed to warrant comparisons between groups and individuals? (2) What evidence is needed to warrant comparisons over time? and (3) What are the value implications, including personal and societal consequences, of using PRO scores? DISCUSSION: Measurement validation is an ongoing process that involves the accumulation of evidence regarding the justification of inferences, actions, and decisions based on measurement scores. These include inferences pertaining to comparisons between groups and comparisons over time as well as consideration of value implications of using PRO scores. Personal and societal consequences must be examined as part of a comprehensive approach to measurement validation. The answers to these three questions are fundamental to the the validity of different types of inferences, actions, and decisions made on PRO scores in health research, health care administration, and clinical practice.

RESUMO

PURPOSE: Response shift (RS) may mask true change in health-related quality of life in longitudinal studies. People with chronic conditions may experience RS as they adapt to their disease, but it is unknown whether fluctuations in disease activity will influence the presence of RS. The study purpose was to test for RS in individuals with inflammatory bowel disease (IBD), a condition characterized by periods of symptom flares and remission. METHODS: Data were from the Manitoba IBD Cohort Study (N = 388). Multi-group confirmatory factor analysis (MG-CFA) and a RS detection method based on structural equation modeling were used to test for reconceptualization, reprioritization, and recalibration RS in participants with consistent active, consistent inactive, and inconsistent disease activity over a 6-month period on the SF-36. RESULTS: The MG-CFA revealed that a weak invariance model with equal factor loadings across groups was the best fit to the baseline SF-36 data. Reconceptualization, uniform recalibration, and non-uniform recalibration RS was detected in the consistent active group, but effect sizes were small. For the consistent inactive group, recalibration RS was observed and effect sizes were small to moderate. For the inconsistent disease activity group, small-to-moderate recalibration RS effects were observed. There was no evidence of reprioritization. CONCLUSIONS: Individuals with a chronic disease may exhibit RS even if they are not actively experiencing symptoms on a consistent basis. Heterogeneity in the type and magnitude of RS effects may be observed in chronic disease patients who experience changes in disease symptoms.
