Validation of five patient-reported outcomes for atopic dermatitis severity in adults.

BACKGROUND: Structured patient-reported outcomes of atopic dermatitis (AD) severity are not standardized in clinical practice. OBJECTIVES: To determine the construct validity, internal consistency, cross-cultural validity and floor or ceiling effects of multiple AD severity assessments. METHODS: This is a cross-sectional, population-based study of 2893 adults, including 602 adults who met a modified set of U.K. diagnostic criteria for AD. AD severity was assessed using self-reported global AD severity, Patient-Oriented Eczema Measure (POEM), Patient-Oriented Scoring Atopic Dermatitis (PO-SCORAD) and its objective and subjective components, and numerical rating scale (NRS)-itch. Quality of life was assessed using Short-Form (SF)-12 mental and physical health scores, Short-Form Six Dimensions (SF-6D) health utility scores and Dermatology Life Quality Index (DLQI). Mental health was assessed with the Hospital Anxiety and Depression Scale (HADS). RESULTS: PO-SCORAD, PO-SCORAD objective and subjective subscores, NRS-itch and POEM all had moderate-to-strong correlations with each other and DLQI, fair-to-moderate correlations with HADS-anxiety and HADS-depression, and inverse correlations with SF-12 mental component score and SF-6D (Pearson correlations, P < 0·001). All scores showed good criterion validity as judged by anova and receiver operator characteristics. PO-SCORAD, PO-SCORAD objective subscore and POEM had similarly good internal consistency (Cronbach's alpha = 0·84, 0·82 and 0·86); the PO-SCORAD subjective subscore was less internally consistent (alpha = 0·57). All scores showed potentially poor cross-cultural validity as demonstrated by uniform and nonuniform differential item functioning by age, sex and/or race/ethnicity for multiple items. There were floor effects for POEM, but not for the other assessments. CONCLUSIONS: PO-SCORAD, PO-SCORAD objective and subjective subscores, NRS-itch and POEM appear to be valid for assessing AD severity in clinical practice. What's already known about this topic? Few studies have demonstrated the validity of the atopic dermatitis severity assessments Patient-Oriented Scoring Atopic Dermatitis (PO-SCORAD), PO-SCORAD subscores, numerical rating scale (NRS)-itch and Patient-Oriented Eczema Measure (POEM). What does this study add? This study demonstrates that PO-SCORAD, PO-SCORAD subscores, NRS-itch and POEM all had good construct validity in the assessment of atopic dermatitis severity in adults. Only POEM demonstrated floor effects. What are the clinical implications of this work? PO-SCORAD, PO-SCORAD subscores, NRS-itch and POEM all appear to have sufficient validity to be used as assessments of atopic dermatitis severity in clinical practice.

Symptoms and diagnosis of anxiety and depression in atopic dermatitis in U.S. adults.

BACKGROUND: The relationship between atopic dermatitis (AD), anxiety and depression in the U.S. adult population is not well established. OBJECTIVES: To determine the relationship of AD and its severity with symptoms and diagnosis of anxiety and depression in U.S. adults. METHODS: A cross-sectional, population-based study of 2893 adults was performed. AD was determined using modified U.K. Diagnostic Criteria. RESULTS: Adults with AD vs. those without AD had higher mean Hospital Anxiety and Depression Scale anxiety (HADS-A) (7·7 vs. 5·6) and depression (HADS-D) (6·0 vs. 4·3) scores and higher prevalences of abnormal (≥ 11) HADS-A (28·6% vs. 15·5%) and HADS-D (13·5% vs. 9·0%) scores. In multivariable linear and logistic regression models controlling for sociodemographics, AD was associated with significantly higher mean HADS-A and HADS-D scores (7·7 and 6·0) and higher odds of abnormal HADS-A [odds ratio (OR) 2·19, 95% confidence interval (CI) 1·65-2·91] and HADS-D scores (OR 1·50, 95% CI 1·04-2·17) (P ≤ 0·03 for all). Mean and abnormal HADS-A and HADS-D scores were increased in moderate and severe/very severe self-reported global AD severity, Patient-Oriented Eczema Measure (POEM), Patient-Oriented Scoring AD (PO-SCORAD), PO-SCORAD itch and sleep (P < 0·0001 for all). All respondents with severe PO-SCORAD, POEM and PO-SCORAD itch had borderline or abnormal HADS-A and HADS-D scores. Adults with AD vs. those without AD had higher prevalence of self-reported healthcare-diagnosed anxiety or depression in the past year (40·0% vs. 17·5%). Many adults with AD who had borderline and/or abnormal HADS-A or HADS-D scores reported no diagnosis of anxiety or depression. CONCLUSIONS: AD is associated with significantly increased anxiety and depression, which may go undiagnosed. What's already known about this topic? Previous studies found higher rates of anxiety and depression in clinical cohorts of patients with atopic dermatitis. What does this study add? This study found dramatically higher rates of anxiety and depression among adults with atopic dermatitis in the U.S. population, which was primarily driven by atopic dermatitis severity. Anxiety and depression often go undiagnosed in adults with atopic dermatitis.

Focal laser ablation as clinical treatment of prostate cancer: report from a Delphi consensus project.

PURPOSE: To define the role of focal laser ablation (FLA) as clinical treatment of prostate cancer (PCa) using the Delphi consensus method. METHODS: A panel of international experts in the field of focal therapy (FT) in PCa conducted a collaborative consensus project using the Delphi method. Experts were invited to online questionnaires focusing on patient selection and treatment of PCa with FLA during four subsequent rounds. After each round, outcomes were displayed, and questionnaires were modified based on the comments provided by panelists. Results were finalized and discussed during face-to-face meetings. RESULTS: Thirty-seven experts agreed to participate, and consensus was achieved on 39/43 topics. Clinically significant PCa (csPCa) was defined as any volume Grade Group 2 [Gleason score (GS) 3+4]. Focal therapy was specified as treatment of all csPCa and can be considered primary treatment as an alternative to radical treatment in carefully selected patients. In patients with intermediate-risk PCa (GS 3+4) as well as patients with MRI-visible and biopsy-confirmed local recurrence, FLA is optimal for targeted ablation of a specific magnetic resonance imaging (MRI)-visible focus. However, FLA should not be applied to candidates for active surveillance and close follow-up is required. Suitability for FLA is based on tumor volume, location to vital structures, GS, MRI-visibility, and biopsy confirmation. CONCLUSION: Focal laser ablation is a promising technique for treatment of clinically localized PCa and should ideally be performed within approved clinical trials. So far, only few studies have reported on FLA and further validation with longer follow-up is mandatory before widespread clinical implementation is justified.

Distribution of atopic dermatitis lesions in United States adults.

BACKGROUND: The distribution of atopic dermatitis (AD) lesions and its impact on quality of life (QOL) is not well established in the US adult population. OBJECTIVE: To elucidate the distribution of AD lesions and its impact on QOL in US adults with AD. METHODS: A cross-sectional, population-based study of 602 adults was performed. AD was determined using modified UK Diagnostic Criteria, and its lesional distribution was assessed. QOL was assessed using Dermatology Life Quality Index (DLQI). Latent class analysis (LCA) was used to determine distinct phenotypes of AD lesional distribution. Multivariable logistic regression was used to determine the relationship between DLQI and distinct phenotypes. RESULTS: The most common sites of skin lesions were reported to be the popliteal fossae, lower legs, dorsal feet and antecubital fossae. Most persons reported partial (19.0%) or complete (63.0%) symmetry of lesions on the extremities. Lesions on the trunk were significantly more common in blacks and Hispanics. Age ≥ 60 years was associated with significantly lower proportions of active lesions on the face and scalp, and significantly higher proportion of lesions on the buttocks or genitals. LCA identified 5 classes of lesional distribution: 1. lower probabilities of lesions affecting any sites; 2. Higher probability of lesions involving the anterior and posterior neck and trunk; 3. lesions involving the antecubital fossae and upper extremities; 4. lesions involving the arms, posterior hands, genitals and buttocks, and to a lesser extent face, palms and legs; 5. lesions affecting all sites. Class-2 (multivariable logistic regression; adjusted odds ratio [95% confidence interval]: 7.19 [3.21-16.07], class-3 (7.11 [3.20-15.80]), class-4 (6.90 [3.07-15.50]) and class-5 (7.92 [3.54-17.71]) were all significantly associated with higher DLQI scores compared to class 1. CONCLUSION: AD is associated with heterogeneous distribution of AD lesions, and distinct phenotypes that are associated with QOL impact.

Epidemiology of atopic dermatitis in adults: Results from an international survey.

BACKGROUND: There are gaps in our knowledge of the prevalence of adult atopic dermatitis (AD). OBJECTIVE: To estimate the prevalence of AD in adults and by disease severity. METHODS: This international, cross-sectional, web-based survey was performed in the United States, Canada, France, Germany, Italy, Spain, United Kingdom, and Japan. Adult members of online respondent panels were sent a questionnaire for AD identification and severity assessment; demographic quotas ensured population representativeness for each country. A diagnosis of AD required subjects to be positive on the modified UK Working Party/ISAAC criteria and self-report of ever having an AD diagnosis by a physician. The proportion of subjects with AD who reported being treated for their condition was determined and also used to estimate prevalence. Severity scales were Patient-Oriented SCORAD, Patient-Orientated Eczema Measure, and Patient Global Assessment. RESULTS: Among participants by region, the point prevalence of adult AD in the overall/treated populations was 4.9%/3.9% in the US, 3.5%/2.6% in Canada, 4.4%/3.5% in the EU, and 2.1%/1.5% in Japan. The prevalence was generally lower for males vs females, and decreased with age. Regional variability was observed within countries. Severity varied by scale and region; however, regardless of the scale or region, proportion of subjects reporting severe disease was lower than mild or moderate disease. CONCLUSIONS: Prevalence of adult AD ranged from 2.1% to 4.9% across countries. Severe AD represented a small proportion of the overall AD population regardless of measure or region.

Systematic review of atopic dermatitis disease definition in studies using routinely collected health data.

BACKGROUND: Routinely collected electronic health data obtained for administrative and clinical purposes are increasingly used to study atopic dermatitis (AD). Methods for identifying AD patients in routinely collected electronic health data differ, and it is unknown how this might affect study results. OBJECTIVES: To evaluate how patients with AD have been identified in studies using routinely collected electronic health data, to determine whether these methods were validated and to estimate how the method for identifying patients with AD affected variability in prevalence estimates. METHODS: We systematically searched PubMed, Embase and Web of Science for studies using routinely collected electronic health data that reported on AD as a primary outcome. Studies of localized AD and other types of dermatitis were excluded. The protocol for this review was registered in PROSPERO (CRD42016037968). RESULTS: In total, 59 studies met eligibility criteria. Medical diagnosis codes for inclusion and exclusion, number of occasions of a code, type of provider associated with a code and prescription data were used to identify patients with AD. Only two studies described validation of their methods and no study reported on disease severity. Prevalence estimates ranged from 0·18% to 38·33% (median 4·91%) and up to threefold variation in prevalence was introduced by differences in the method for identifying patients with AD. CONCLUSIONS: This systematic review highlights the need for clear reporting of methods for identifying patients with AD in routinely collected electronic health data to allow for meaningful interpretation and comparison of results.

Expanding the Menu of HIV Prevention Options: A Qualitative Study of Experiences with Long-Acting Injectable Cabotegravir as PrEP in the Context of a Phase II Trial in the United States.

Adherence challenges with oral pre-exposure prophylaxis have stimulated interest in alternate modes of administration including long-acting injections. We conducted 30 in-depth interviews with 26 male trial participants and 4 clinical providers in a Phase IIa study (ÉCLAIR) evaluating the use of long-acting cabotegravir (CAB-LA) injections in New York and San Francisco. Interviews exploring attitudes and experiences with CAB-LA were audiotaped, transcribed, and analyzed using thematic content analysis. Despite a high frequency of some level of side effects, almost all participants reported being interested in continuing with CAB-LA, versus a daily oral, due to its convenience and the perceived advantage of not worrying about adhering to pills. Providers reinforced the importance of CAB-LA as a prevention option and the need for guidelines to assist patient decision-making. Further research is needed on the acceptability of CAB-LA among men and women at higher risk for HIV in different settings.

Administration of vorinostat disrupts HIV-1 latency in patients on antiretroviral therapy.

Despite antiretroviral therapy, proviral latency of human immunodeficiency virus type 1 (HIV-1) remains a principal obstacle to curing the infection. Inducing the expression of latent genomes within resting CD4(+) T cells is the primary strategy to clear this reservoir. Although histone deacetylase inhibitors such as suberoylanilide hydroxamic acid (also known as vorinostat, VOR) can disrupt HIV-1 latency in vitro, the utility of this approach has never been directly proven in a translational clinical study of HIV-infected patients. Here we isolated the circulating resting CD4(+) T cells of patients in whom viraemia was fully suppressed by antiretroviral therapy, and directly studied the effect of VOR on this latent reservoir. In each of eight patients, a single dose of VOR increased both biomarkers of cellular acetylation, and simultaneously induced an increase in HIV RNA expression in resting CD4(+) cells (mean increase, 4.8-fold). This demonstrates that a molecular mechanism known to enforce HIV latency can be therapeutically targeted in humans, provides proof-of-concept for histone deacetylase inhibitors as a therapeutic class, and defines a precise approach to test novel strategies to attack and eradicate latent HIV infection directly.

The ASSURE study: HIV-1 suppression is maintained with bone and renal biomarker improvement 48 weeks after ritonavir discontinuation and randomized switch to abacavir/lamivudine + atazanavir.

OBJECTIVES: HIV treatment guidelines endorse switching or simplification of antiretroviral therapy in therapy-experienced patients with suppressed viraemia; ritonavir discontinuation may also enhance tolerability and reduce long-term adverse events (AEs). This open-label, multicentre, noninferiority study enrolled HIV-1-infected, treatment-experienced adults with confirmed HIV-1 RNA ≤ 75 HIV-1 RNA copies/mL currently receiving tenofovir/emtricitabine + atazanavir/ritonavir (TDF/FTC + ATV/r) for ≥ 6 months with no reported history of virological failure. METHODS: Participants were randomized 1:2 to continue current treatment or switch to abacavir/lamivudine + atazanavir (ABC/3TC + ATV). Endpoints included the proportion of participants with HIV-1 RNA < 50 copies/mL by time to loss of virological response (TLOVR), AEs, fasting lipids, and inflammatory, coagulation, bone and renal biomarkers. RESULTS: After 48 weeks, 76% (152 of 199) of ABC/3TC + ATV-treated and 79% (77 of 97) of TDF/FTC + ATV/r-treated participants had HIV-1 RNA < 50 copies/mL (TLOVR; P = 0.564). Other efficacy analyses yielded similar results. Rates of new grade 2-4 AEs were 45% in both groups, but an excess of hyperbilirubinaemia made the rate of treatment-emergent grade 3-4 laboratory abnormalities higher with TDF/FTC + ATV/r (36%) compared with ABC/3TC + ATV (19%). Most fasting lipid levels remained stable over time; high-density lipoprotein (HDL) cholesterol increased modestly in ABC/3TC + ATV-treated participants. Bone and renal biomarkers improved significantly between baseline and week 48 in participants taking ABC/3TC + ATV and were stable in participants taking TDF/FTC + ATV/r. No significant changes occurred in any inflammatory or coagulation biomarker within or between treatment groups. CONCLUSIONS: The ABC/3TC + ATV treatment-switch group had similar viral suppression rates up to 48 weeks to the TDF/FTC + ATV/r comparator group, with lower rates of moderate- to high-grade hyperbilirubinaemia and improvements in bone and renal biomarkers.

Association of diabetic foot ulcer and death in a population-based cohort from the United Kingdom.

AIMS: The presence of diabetic foot ulcers is strongly associated with an increased risk of death. In this study, we investigate whether the effects of diabetes-associated complications can explain the apparent relationship between diabetic foot ulcers and death. METHODS: We analysed data from 414 523 people with diabetes enrolled in practices associated with The Health Improvement Network in the United Kingdom. Our methods were designed to control for potential confounders in order to isolate the relationship between diabetic foot ulcers and death. Using proportional hazards models and the area under the receiver operator curve, we evaluated the effects of diabetic foot ulcers and the covariates on death. RESULTS: Among the patients, 20 737 developed diabetic foot ulcers; 5.0% of people with new ulcers died within 12 months of their first foot ulcer visit and 42.2% of people with foot ulcers died within 5 years. After controlling for major known complications of diabetes that might influence mortality, the correlation between diabetic foot ulcers and death remained strong with a fully adjusted hazard ratio of 2.48 (95% confidence interval: 2.43, 2.54). Geographic variance existed but was not spatially associated. CONCLUSIONS: Diabetic foot ulcers are linked to an increased risk of death. This cannot be explained by other common risk factors. These results suggest that either there are major unknown risk factors associated with both diabetic foot ulcers and death, or that diabetic foot ulceration itself is a serious threat, which seems unlikely. A diabetic foot ulcer should be seen as a major warning sign for mortality, necessitating closer medical follow-up.

HIV eradication symposium: will the brain be left behind?

On 18 July 2014, the National Institute of Mental Health in collaboration with ViiV Health Care and Boehringer Ingelheim supported a symposium on HIV eradication and what it meant for the brain. The symposium was an affiliated event to the 20th International AIDS Conference. The meeting was held in Melbourne, Australia, and brought together investigators currently working on HIV eradication together with investigators who are working on the neurological complications of HIV. The purpose of the meeting was to bring the two fields of HIV eradication and HIV neurology together to foster dialogue and cross talk to move the eradication field forward in the context of issues relating to the brain as a potential reservoir of HIV. The outcomes of the symposium were that there was substantive but not definitive evidence for the brain as an HIV reservoir that will provide a challenge to HIV eradication. Secondly, the brain as a clinically significant reservoir for HIV is not necessarily present in all patients. Consequently, there is an urgent need for the development of biomarkers to identify and quantify the HIV reservoir in the brain. Lastly, when designing and developing eradication strategies, it is critical that approaches to target the brain reservoir be included.

Report from the third international consensus meeting to harmonise core outcome measures for atopic eczema/dermatitis clinical trials (HOME).

This report provides a summary of the third meeting of the Harmonising Outcome Measures for Eczema (HOME) initiative held in San Diego, CA, U.S.A., 6-7 April 2013 (HOME III). The meeting addressed the four domains that had previously been agreed should be measured in every eczema clinical trial: clinical signs, patient-reported symptoms, long-term control and quality of life. Formal presentations and nominal group techniques were used at this working meeting, attended by 56 voting participants (31 of whom were dermatologists). Significant progress was made on the domain of clinical signs. Without reference to any named scales, it was agreed that the intensity and extent of erythema, excoriation, oedema/papulation and lichenification should be included in the core outcome measure for the scale to have content validity. The group then discussed a systematic review of all scales measuring the clinical signs of eczema and their measurement properties, followed by a consensus vote on which scale to recommend for inclusion in the core outcome set. Research into the remaining three domains was presented, followed by discussions. The symptoms group and quality of life groups need to systematically identify all available tools and rate the quality of the tools. A definition of long-term control is needed before progress can be made towards recommending a core outcome measure.

Highlights from the Tenth International Workshop on HIV Persistence during Therapy, December 13-16, 2022, Miami, Florida-USA.

The International Workshop on HIV Persistence during Therapy provides a forum in which HIV/AIDS researchers gather to share the latest research findings related to viral reservoirs and cure. The Tenth Workshop, which was attended by over 400 delegates, extended over 4 days and comprised eight sessions covering topics from the basic science of viral persistence to therapeutic approaches to HIV cure. Furthermore, satellite sessions on the first day of the Conference featuring cure research endeavours being pursued by the Bill and Melinda Gates Foundation as well as those being coordinated under the National Institutes of Health Martin Delaney Collaboratory program, provided important updates on research advances being made in these initiatives. As with previous conferences, the International Workshop on HIV Persistence during Therapy is primarily abstract-driven with only one invited talk for each of the sessions. This format, therefore, increases the number of presentations from early-stage investigators. Furthermore, presentations by Community representatives illustrated approaches to creating cure research literacy with effective messaging for the Community. The following article offers a synopsis of the meeting sessions. Due to space constraints, some presentations may have only been briefly discussed. Nevertheless, the Workshop abstracts can be found online (https://www/sciencedirect.com/journal/journal-of-virus-eradication/vol/8/suppl/S).

Validity of The Health Improvement Network (THIN) for the study of psoriasis.

BACKGROUND: Psoriasis is a common disease frequently studied in large databases. To date the validity of psoriasis information has not been established in The Health Improvement Network (THIN). OBJECTIVES: To investigate the validity of THIN for identifying patients with psoriasis and to determine if the database can be used to determine the natural history of the disease. METHODS: First, we conducted a cross-sectional study to determine if psoriasis prevalence in THIN is similar to expected. Second, we created a cohort of 4900 patients, aged 45-64 years, with a psoriasis diagnostic Read Code and surveyed their general practitioners (GPs) to confirm the diagnosis clinically. Third, we created models to determine if psoriasis descriptors (extent, severity, duration and dermatologist confirmation) could be accurately captured from database records. RESULTS: Psoriasis prevalence was 1·9%, and showed the characteristic age distribution expected. GP questionnaires were received for 4634 of 4900 cohort patients (95% response rate), and psoriasis diagnoses were confirmed in 90% of patients. Duration of disease in the database showed substantial agreement with physician query (κ = 0·69). GPs confirmed that the psoriasis diagnosis was corroborated by a dermatologist in 91% of patients whose database records contained a dermatology referral code associated with a psoriasis code. We achieved good discrimination between patients with and without extensive disease based on the number of psoriasis codes received per year (area under curve = 0·8). CONCLUSIONS: THIN is a valid data resource for studying psoriasis and can be used to identify characteristics of the disease such as duration and confirmation by a dermatologist.
