RESUMO

OBJECTIVES: Severe obesity in nursing home (NH) residents is associated with specialized care needs, limited mobility, and challenges in daily living. The COVID-19 pandemic strained NH resources and exacerbated staffing shortages. This study aimed to assess the ability of US NHs to accept and care for residents with severe obesity post-COVID, as well as associated NH factors. DESIGN: Cross-sectional nationwide survey of NH administrators (2021-2022). SETTING AND PARTICIPANTS: 290 NHs from a national sample (n = 224) and a targeted sample in Massachusetts and New Jersey (n = 66). METHODS: A survey designed to assess how NHs approach admitting and caring for people with severe obesity before and after COVID was fielded from 2021 to 2022. Responses were linked to facility information from the Certification and Survey Provider Enhanced Reports, Minimum Data Set, Nursing Home Compare, Area Health Resources File, and US Diabetes Surveillance System. Multivariable logistic regression was used to assess the effect of organizational and survey response variables. RESULTS: Of the 2503 surveys sent to US NHs, 1923 were sent to the national NH stratified sample, and 580 were sent to the MA/NJ sample. Overall, 12% (301 of 2503) of NHs surveyed responded. The response rates were similar between the 2 samples. Of 290 NHs with complete data, 34% reported being unlikely to accept residents with severe obesity after COVID-19, compared with 25% before the pandemic (P < .001). The main barriers to acceptance were staffing shortages and difficulties meeting equipment and space needs. NHs with higher proportions of Black residents were more likely to admit individuals with severe obesity. CONCLUSIONS AND IMPLICATIONS: The decline in acceptance of residents with severe obesity during and after COVID-19 highlights potential challenges that this population faces in accessing care. Our results also raise concerns that an intersection of disparities may exist in Black patients with severe obesity.

RESUMO

OBJECTIVE: To assess the effect of geographic factors on fertility-sparing treatment or assisted reproductive technology (ART) utilization among women with gynecologic or breast cancers. METHODS: We conducted a cohort study of reproductive-aged patients (18-45 years) with early-stage cervical, endometrial, or ovarian cancer or stage I-III breast cancer diagnosed between January 2000 and December 2015 using linked data from the California Cancer Registry, the California Office of Statewide Health Planning and Development, and the Society for Assisted Reproductive Technology. Generalized linear mixed models were used to evaluate associations between distance from fertility and gynecologic oncology clinics, as well as California Healthy Places Index score (a Census-level composite community health score), and ART or fertility-sparing treatment receipt. RESULTS: We identified 7,612 women with gynecologic cancer and 35,992 women with breast cancer. Among all patients, 257 (0.6%) underwent ART. Among patients with gynecologic cancer, 1,676 (22.0%) underwent fertility-sparing treatment. Stratified by quartiles, residents who lived at increasing distances from gynecologic oncology or fertility clinics had decreased odds of undergoing fertility-sparing treatment (gynecologic oncology clinics: Q2, odds ratio [OR] 0.76, 95% CI, 0.63-0.93, P=.007; Q4, OR 0.72, 95% CI, 0.56-0.94, P=.016) (fertility clinics: Q3, OR 0.79, 95% CI, 0.65-0.97, P=.025; Q4, OR 0.67, 95% CI, 0.52-0.88, P=.004), whereas this relationship was not observed among women who resided within other quartiles (gynecologic oncology clinics: Q3, OR 0.81 95% CI, 0.65-1.01, P=.07; fertility clinics: Q2, OR 0.87 95% CI, 0.73-1.05, P=.15). Individuals who lived in communities with the highest (51st-100th percentile) California Healthy Places Index scores had greater odds of undergoing fertility-sparing treatment (OR 1.29, 95% CI, 1.06-1.57, P=.01; OR 1.66, 95% CI, 1.35-2.04, P=.001, respectively). The relationship between California Healthy Places Index scores and ART was even more pronounced (Q2 OR 1.9, 95% CI, 0.99-3.64, P=.05; Q3 OR 2.86, 95% CI, 1.54-5.33, P<.001; Q4 OR 3.41, 95% CI, 1.83-6.35, P<.001). CONCLUSION: Geographic disparities affect fertility-sparing treatment and ART rates among women with gynecologic or breast cancer. By acknowledging geographic factors, health care systems can ensure equitable access to fertility-preservation services.

RESUMO

Identifying therapeutic oligonucleotides that are cross-reactive to experimental animal species can dramatically accelerate the process of preclinical development and clinical translation. Here, we identify fully chemically-modified small interfering RNAs (siRNAs) that are cross-reactive to Janus kinase 1 (JAK1) in humans and a large variety of other species. We validated the identified siRNAs in silencing JAK1 in cell lines and skin tissues of multiple species. JAK1 is one of the four members of the JAK family of tyrosine kinases that mediate the signaling transduction of many inflammatory cytokine pathways. Dysregulation of these pathways is often involved in the pathogenesis of various immune disorders, and modulation of JAK family enzymes is an effective strategy in the clinic. Thus, this work may open up unprecedented opportunities for evaluating the modulation of JAK1 in many animal models of human inflammatory skin diseases. Further chemical engineering of the optimized JAK1 siRNAs may expand the utility of these compounds for treating immune disorders in additional tissues.

RESUMO

BACKGROUND: Equine grass sickness (EGS) is a frequently fatal multisystem neuropathy of equids. The aetiology is unknown; proposed causes include toxicoinfection with Clostridium botulinum and a mycotoxicosis. The effect of EGS on the organisation and structural integrity of the skeletal neuromuscular junction (NMJ), the target of botulinum neurotoxins (BoNTs), is unknown. OBJECTIVES: To compare the organisation and structural integrity of skeletal NMJs from EGS horses, control horses and one horse with a presumptive diagnosis of botulism. STUDY DESIGN: Blinded, retrospective case control. METHODS: NMJs in samples of diaphragm or intercostal muscle from six EGS horses, three control horses and one equine botulism case were compared using electron microscopy, morphometry and confocal light microscopy. RESULTS: A significantly higher percentage of EGS NMJs had abnormal morphology (EGS 72.2%, 95% CI 55.6-84.4; Controls 6.9%, 1.7-23.8; OR 35.1, 8.47-244.8; p < 0.001). EGS NMJs had a significantly lower mean volume fraction occupied by synaptic vesicles (SVs) (EGS 18.7%, 12.6-28.0; Controls 36.3%, 20.8-63.4; p = 0.024). EGS NMJs had evidence of accelerated SV exocytosis and SV depletion, accumulation of neurofilament-like material in terminal boutons and/or bouton degeneration. NMJs from the botulism horse had dense packing of SVs towards the presynaptic membrane active zone, consistent with BoNT intoxication, but had absence of the abnormalities identified in EGS NMJs. MAIN LIMITATIONS: Group sizes were limited by difficulties obtaining suitably processed samples. Ages of control and EGS horses differed. Botulism was diagnosed based on clinical and post mortem findings. CONCLUSIONS: EGS is associated with major changes in skeletal NMJ ultrastructure that are inconsistent with the effects of BoNTs. SV depletion may reflect increased exocytosis coupled with reduced repopulation of SVs via anterograde axonal transport and endocytosis, consistent with the action of an excitatory presynaptic toxin and/or neurotransmitter reuptake inhibitor. Skeletal NMJs represent a previously unrecognised target for the toxin that causes EGS.

RESUMO

Chemokines play critical roles in the recruitment and activation of immune cells in both homeostatic and pathologic conditions. Here, we examined chemokine ligand-receptor pairs to better understand the immunopathogenesis of cutaneous lupus erythematosus (CLE), a complex autoimmune connective tissue disorder. We used suction blister biopsies to measure cellular infiltrates with spectral flow cytometry in the interface dermatitis reaction, as well as 184 protein analytes in interstitial skin fluid using Olink targeted proteomics. Flow and Olink data concordantly demonstrated significant increases in T cells and antigen presenting cells (APCs). We also performed spatial transcriptomics and spatial proteomics of punch biopsies using digital spatial profiling (DSP) technology on CLE skin and healthy margin controls to examine discreet locations within the tissue. Spatial and Olink data confirmed elevation of interferon (IFN) and IFN-inducible CXCR3 chemokine ligands. Comparing involved versus uninvolved keratinocytes in CLE samples revealed upregulation of essential inflammatory response genes in areas near interface dermatitis, including AIM2. Our Olink data confirmed upregulation of Caspase 8, IL-18 which is the final product of AIM2 activation, and induced chemokines including CCL8 and CXCL6 in CLE lesional samples. Chemotaxis assays using PBMCs from healthy and CLE donors revealed that T cells are equally poised to respond to CXCR3 ligands, whereas CD14+CD16+ APC populations are more sensitive to CXCL6 via CXCR1 and CD14+ are more sensitive to CCL8 via CCR2. Taken together, our data map a pathway from keratinocyte injury to lymphocyte recruitment in CLE via AIM2-Casp8-IL-18-CXCL6/CXCR1 and CCL8/CCR2, and IFNG/IFNL1-CXCL9/CXCL11-CXCR3.

RESUMO

Characterizing the mechanisms influencing the distribution of genetic variation in aquatic species can be difficult due to the dynamic nature of hydrological landscapes. In North America's Central Highlands, a complex history of glacial dynamics, long-term isolation, and secondary contact have shaped genetic variation in aquatic species. Although the effects of glacial history have been demonstrated in many taxa, responses are often lineage- or species-specific and driven by organismal ecology. In this study, we reconstruct the evolutionary history of a freshwater mussel species complex using a suite of mitochondrial and nuclear loci to resolve taxonomic and demographic uncertainties. Our findings do not support Pleurobema rubrum as a valid species, which is proposed for listing as threatened under the U.S. Endangered Species Act. We synonymize P. rubrum under Pleurobema sintoxia-a common and widespread species found throughout the Mississippi River Basin. Further investigation of patterns of genetic variation in P. sintoxia identified a complex demographic history, including ancestral vicariance and secondary contact, within the Eastern Highlands. We hypothesize these patterns were shaped by ancestral vicariance driven by the formation of Lake Green and subsequent secondary contact after the last glacial maximum. Our inference aligns with demographic histories observed in other aquatic taxa in the region and mirrors patterns of genetic variation of a freshwater fish species (Erimystax dissimilis) confirmed to serve as a parasitic larval host for P. sintoxia. Our findings directly link species ecology to observed patterns of genetic variation and may have significant implications for future conservation and recovery actions of freshwater mussels.

RESUMO

Social distancing interrupted transmission patterns of contact-driven infectious agents such as norovirus during the Covid-19 pandemic. Since routine surveillance of norovirus was additionally disrupted during the pandemic, traditional naïve forecasts that rely only on past public health surveillance data may not reliably represent norovirus activity. This study investigates the use of statistical modelling to predict the number of norovirus laboratory reports in England 4-weeks ahead of time before and during Covid-19 pandemic thus providing insights to inform existing practices in norovirus surveillance in England. We compare the predictive performance from three forecasting approaches that assume different underlying structure of the norovirus data and utilized various external data sources including mobility, air temperature and relative internet searches (Time Series and Regularized Generalized Linear Model, and Quantile Regression Forest). The performance of each approach was evaluated using multiple metrics, including a relative prediction error against the traditional naive forecast of a five-season mean. Our data suggest that all three forecasting approaches improve predictive performance over the naïve forecasts, especially in the 2020/21 season (30-45% relative improvement) when the number of norovirus reports reduced. The improvement ranged from 7 to 22% before the pandemic. However, performance varied: regularized regression incorporating internet searches showed the best forecasting score pre-pandemic and the time series approach achieved the best results post pandemic onset without external data. Overall, our results demonstrate that there is a significant value for public health in considering the adoption of more sophisticated forecasting tools, moving beyond traditional naïve methods, and utilizing available software to enhance the precision and timeliness of norovirus surveillance in England.

RESUMO

BACKGROUND AND OBJECTIVES: The prevalence of resident obesity in nursing homes has increased dramatically from 22% to 28% between 2005 and 2015. To provide care for people with obesity, nursing homes have changed their admissions, staffing, and equipment, but underlying these changes are increased resources and financial costs of care. The purpose of this study is to describe nursing home organizational aspects of caring for older adults with obesity, with a focus on economic factors, from the perspective of nursing home staff and leadership. RESEARCH DESIGN AND METHODS: This qualitative study used descriptive approaches; data were collected through semi-structured telephone interviews. Of 77 nursing home staff and leaders identified as potential study participants, 6 were ineligible, and 71 participated in the study through interviews conducted from 2019 to 2022. RESULTS: Four primary themes described the issues surrounding cost of care for obesity in nursing homes: inefficient and risky use of staff time in a setting of persistent staff shortage, expensive and unique equipment needs, inadequate general reimbursement with an absence of obesity-specific reimbursement supplements, and competing short and long-term management solutions. DISCUSSION AND IMPLICATIONS: This qualitative study of nursing home staff and leadership underscores a need for improved approaches to funding obesity care within existing nursing payment models. The increasing prevalence of obesity and the burden of the costs of obesity care for nursing homes will escalate this need over the coming decade.

RESUMO

Inhibition of Janus kinase (JAK) family enzymes is a popular strategy for treating inflammatory and autoimmune skin diseases. In the clinic, small molecule JAK inhibitors show distinct efficacy and safety profiles, likely reflecting variable selectivity for JAK subtypes. Absolute JAK subtype selectivity has not yet been achieved. Here, we rationally design small interfering RNAs (siRNAs) that offer sequence-specific gene silencing of JAK1, narrowing the spectrum of action on JAK-dependent cytokine signaling to maintain efficacy and improve safety. Our fully chemically modified siRNA supports efficient silencing of JAK1 expression in human skin explant and modulation of JAK1-dependent inflammatory signaling. A single injection into mouse skin enables five weeks of duration of effect. In a mouse model of vitiligo, local administration of the JAK1 siRNA significantly reduces skin infiltration of autoreactive CD8+ T cells and prevents epidermal depigmentation. This work establishes a path toward siRNA treatments as a new class of therapeutic modality for inflammatory and autoimmune skin diseases.

RESUMO

BACKGROUND: Efficacy of ruxolitinib cream, a topical Jak1/Jak2 inhibitor, was demonstrated in a phase 2 trial in patients with vitiligo. OBJECTIVE: This study aimed to characterize circulating inflammatory biomarker profiles in patients who demonstrated ≥50% improvement in facial Vitiligo Area Scoring Index scores by week 24 (group 1) and those who did not (group 2). DESIGN: This was a posthoc analysis of a multicenter, randomized, double-blind, vehicle-controlled, phase 2 study in which screening was conducted between June 7, 2017 and March 21, 2018. POPULATION: Patients aged between 18 and 75 years with vitiligo, including depigmentation affecting ≥0.5% of body surface area on the face and ≥3% of body surface area on nonfacial areas, were eligible. INTERVENTION: Patients applied 1.5% ruxolitinib cream to lesions once or twice daily for 52 weeks. MAIN OUTCOMES AND MEASURES: Patients were grouped by achievement of ≥50% improvement in facial Vitiligo Area Scoring Index at week 24. Proteomic analysis was performed on baseline serum samples. RESULTS: Mean ± standard error facial Vitiligo Area Scoring Index in group 1 (n = 30) versus group 2 (n = 27) improved by 79.9 ± 4.0% versus 1.1 ± 7.3% and 91.9 ± 1.5% versus 25.1 ± 13.4% at weeks 24 and 52, respectively. Broad proteomic analysis revealed 76 proteins (of 1,104 tested) that were differentially expressed between groups 1 and 2 at baseline (P < 0.05). Ten distinct proteins were upregulated in group 1; 64 were elevated in group 2. CONCLUSION: This analysis identified potential differences between patients who achieved ≥50% improvement in facial Vitiligo Area Scoring Index at 24 weeks and those who did not that require deeper scientific interrogation and may be important in stratifying therapeutic benefit for patients with vitiligo. TRIAL REGISTRATION: The original study was registered at ClinicalTrials.gov, NCT03099304.

RESUMO

BACKGROUND: Non-word repetition (NWR) tests are an important way speech and language therapists (SaLTs) assess language development. NWR tests are often scored whilst participants make their responses (i.e., in real time) in clinical and research reports (documented here via a secondary analysis of a published systematic review). AIMS: The main aim was to determine the extent to which real-time coding of NWR stimuli at the whole-item level (as correct/incorrect) was predicted by models that had varying levels of detail provided from phonemic transcriptions using several linear mixed method (LMM) models. METHODS & PROCEDURES: Live scores and recordings of responses on the universal non-word repetition (UNWR) test were available for 146 children aged between 3 and 6 years where the sample included all children starting in five UK schools in one year or two consecutive years. Transcriptions were made of responses to two-syllable NWR stimuli for all children and these were checked for reliability within and between transcribers. Signal detection analysis showed that consonants were missed when judgments were made live. Statistical comparisons of the discrepancies between target stimuli and transcriptions of children's responses were then made and these were regressed against live score accuracy. Six LMM models (three normalized: 1a, 2a, 3a; and three non-normalized: 1b, 2b, 3b) were examined to identify which model(s) best captured the data variance. Errors on consonants for live scores were determined by comparison with the transcriptions in the following ways (the dependent variables for each pair of models): (1) consonants alone; (2) substitutions, deletions and insertions of consonants identified after automatic alignment of live and transcribed materials; and (3) as with (2) but where substitutions were coded further as place, manner and voicing errors. OUTCOMES & RESULTS: The normalized model that coded consonants in non-words as 'incorrect' at the level of substitutions, deletions and insertions (2b) provided the best fit to the real-time coding responses in terms of marginal R2 , Akaike's information criterion (AIC) and Bayesian information criterion (BIC) statistics. CONCLUSIONS & IMPLICATIONS: Errors that occur on consonants when non-word stimuli are scored in real time are characterized solely by the substitution, deletion and insertion measure. It is important to know that such errors arise when real-time judgments are made because NWR tasks are used to assess and diagnose several cognitive-linguistic impairments. One broader implication of the results is that future work could automate the analysis procedures to provide the required information objectively and quickly without having to transcribe data. WHAT THIS PAPER ADDS: What is already known on this subject Children and patients with a wide range of cognitive and language difficulties are less accurate relative to controls when they attempt to repeat non-words. Responses to non-words are often scored as correct or incorrect at the time the test is conducted. Limited assessments of this scoring procedure have been conducted to date. What this study adds to the existing knowledge Live NWR scores made by 146 children were available and the accuracy of these judgements was assessed here against ones based on phonemic transcriptions. Signal detection analyses showed that live scoring missed consonant errors in children's responses. Further analyses, using linear mixed effect models, showed that live judgments led to consonant substitution, deletion and insertion errors. What are the practical and clinical implications of this work? Improved and practicable NWR scoring procedures are required to provide SaLTs with better indications about children's language development (typical and atypical) and for clinical assessments of older people. The procedures currently used miss substitutions, deletions and insertions. Hence, procedures are required that provide the information currently only available when materials are transcribed manually. The possibility of training automatic speech recognizers to provide this level of detail is raised.

RESUMO

BACKGROUND: The treatment of vitiligo can be challenging and depends on several factors such as the subtype, disease activity, vitiligo extent, and treatment goals. Vitiligo usually requires a long-term approach. To improve the management of vitiligo worldwide, a clear and up-to-date guide based on international consensus with uniform stepwise recommendations is needed. OBJECTIVES: To reach an international consensus on the nomenclature and to develop a management algorithm for the diagnosis, assessment, and treatment of vitiligo. METHODS: In this consensus statement, a consortium of 42 international vitiligo experts and four patient representatives participated in online and live meetings to develop a consensus management strategy for vitiligo. At least two vitiligo experts summarized the evidence of topics included in the algorithms. A survey was utilized to resolve remaining issues among a core group of eight experts. Subsequently, the unanimous recommendations were finalized and validated based on further input from the entire group during two live meetings. RESULTS: The algorithms highlight the importance of shared decision-making. Dermatologists are encouraged to provide patients with detailed explanations of the prognosis and expected therapeutic outcomes based on clinical examination. The treatment goal should be discussed and clearly emphasized to patients given the different approaches for disease stabilization and repigmentation. The evaluation of disease activity remains a cornerstone in the tailor-made approach to vitiligo patients. CONCLUSIONS: These new treatment algorithms are intended to guide clinical decision-making in clinical practice. Promising novel therapies for vitiligo are on the horizon, further highlighting the need for reliable outcome measurement instruments and greater emphasis on shared decision-making.

RESUMO

BACKGROUND: The treatment of vitiligo can be challenging. Up-to-date agreed consensus recommendations on the use of topical and systemic therapies to facilitate the clinical management of vitiligo are currently lacking. OBJECTIVES: To develop internationally agreed-upon expert-based recommendations for the treatment of vitiligo. METHODS: In this consensus statement, a consortium of 42 international vitiligo experts and four patient representatives participated in different online and live meetings to develop a consensus management strategy for vitiligo. At least two vitiligo experts summarized the evidence for different topics included in the algorithms. A survey was then given to a core group of eight experts to resolve the remaining issues. Subsequently, the recommendations were finalized and validated based on further input from the entire group during two live meetings. RESULTS: The recommendations provided summarize the latest evidence regarding the use of topical therapies (steroids, calcineurin inhibitors and Jak-inhibitors) and systemic therapies, including steroids and other systemic immunomodulating or antioxidant agents. The different modalities of phototherapies (NB-UVB, photochemotherapy, excimer devices and home phototherapy), which are often combined with other therapies, are also summarized. Interventional approaches as well as depigmentation strategies are presented for specific indications. Finally, the status of innovative and targeted therapies under development is discussed. CONCLUSIONS: This international consensus statement culminated in expert-based clinical practice recommendations for the treatment of vitiligo. The development of new therapies is ongoing in vitiligo, and this will likely improve the future management of vitiligo, a disease that still has many unmet needs.

RESUMO

Importance: Patients with vitiligo often have impaired quality of life (QOL) and experience substantial psychosocial burden. Objective: To explore the global association of vitiligo with QOL and mental health from the patient perspective. Design, Setting, and Participants: This qualitative study of the cross-sectional population-based Vitiligo and Life Impact Among International Communities (VALIANT) study was conducted from May 6, 2021, to June 21, 2021. Potential participants for this qualitative study were recruited from an online panel in 17 countries. Of 5859 surveyed adults (aged ≥18 years) who reported a vitiligo diagnosis, 3919 (66.9%) completed the survey, and 3541 (60.4%) were included in the analysis. Exposures: Patients were asked questions regarding their emotional well-being, including QOL and mental health. Main Outcomes and Measures: Reported analyses are descriptive and hypothesis generating. Vitiligo Impact Patient scale (VIPs) scores ranged from 0 to 60, with higher scores indicating more psychosocial burden. Results: The median age of the 3541 patients was 38 years (range, 18-95 years), and 1933 (54.6%) were male; 1602 patients (45.2%) had more than 5% affected body surface area (BSA; Self-Assessment Vitiligo Extent Score assessed), and 1445 patients (40.8%) had Fitzpatrick skin types IV to VI (ie, darker skin). The mean (SD) global short-form VIPs score was 27.3 (15.6) overall; patients from India (mean [SD], 40.2 [14.1]) reported the highest scores (ie, most burden). The QOL burden according to the scale was profound for patients with more than 5% affected BSA (mean [SD] score, 32.6 [14.2]), darker skin (mean [SD] score, 31.2 [15.6]), and lesions on the face (mean [SD] score, 30.0 [14.9]) or hands (mean [SD], 29.2 [15.2]). At least 40% of patients globally reported that vitiligo frequently affected aspects of their daily lives, including choosing clothes to wear (1956 of 3541 [55.2%]). Most patients (2103 of 3541 [59.4%]) reported concealing their vitiligo frequently. More than half of patients (2078 of 3541 [58.7%]) reported diagnosed mental health conditions, including anxiety (1019 of 3541 [28.8%]) and depression (866 of 3541 [24.5%]). The Patient Health Questionnaire-9 depression screener showed that 55.0% of patients (1948 of 3541) had moderate to severe depressive symptoms; the highest rates were in India (271 of 303 [89.4%]) and among patients with more than 5% affected BSA (1154 of 1602 [72.0%]) and darker skin (987 of 1445 [68.3%]). Conclusions and Relevance: This qualitative study found that, globally, patients with vitiligo reported being substantially affected in their emotional well-being, daily lives, and psychosocial health; the burden was typically greatest among patients with more than 5% affected BSA, darker skin types, and lesions on the face or hands. Survey findings suggest that patients reported having altered their behavior, expressed clear discontent, and have symptoms consistent with depression, which may be underdiagnosed.

RESUMO

BACKGROUND: Vitiligo is a chronic autoimmune disease affecting melanocytes, resulting in skin depigmentation. Patients with vitiligo often have reduced quality of life and comorbid autoimmune conditions and have reported a lack of available treatments for their vitiligo. OBJECTIVES: The Vitiligo and Life Impact Among International Communities (VALIANT) study is the first global survey to explore the natural history and management of vitiligo from the perspectives of patients and healthcare professionals (HCPs). METHODS: The survey recruited adults (≥ 18 years) diagnosed with vitiligo and HCPs treating patients with vitiligo via an online panel in 17 countries. Patients were queried regarding clinical characteristics and vitiligo treatment. HCPs were queried regarding diagnosis and management of patients with vitiligo. RESULTS: Included in the analysis were 3541 patients and 1203 HCPs. Nearly half (45.2%) of the patients had > 5% affected body surface area; 57.1% reported family history. Patients obtained formal diagnosis after a mean (SD) of 2.4 (4.1) years; 44.9% reported previous misdiagnosis. Many patients (56.7%) reported being told that vitiligo could not be treated; 53.9% of HCPs believed patients who never treated their vitiligo had been told that vitiligo could not be treated. One-quarter of HCPs (26.3%) did not believe that an effective therapy for vitiligo exists; 44.6% of patients reported giving up on finding an effective therapy. Top treatment goals for patients and HCPs, respectively, were reduction or cessation of spread (24.7% and 18.5%) and repigmentation (22.5% and 37.2%). Patient perception of effective care was similar for treatment by dermatologists (66.9%) and primary care HCPs (67.0%). CONCLUSIONS: Patients with vitiligo and HCPs reported similar treatment goals and expressed frustration with the lack of effective therapies. Patients reported high rates of initial misdiagnosis; many ceased seeking healthcare because they perceived that vitiligo could not be treated. The findings highlight the need for earlier diagnosis and improved disease management for vitiligo.

RESUMO

The melanocyte-keratinocyte transplantation procedure (MKTP) treats stable and recalcitrant vitiligo. Despite careful selection of candidates based on clinical stability, the success of the procedure is unpredictable. The aim of our study was to define the immunological profile of stable vitiligo lesions undergoing MKTP and correlate them with clinical outcomes. We included 20 MKTP candidates with vitiligo and a patient with piebaldism as a control. Prior to MKTP, T-cell subsets and chemokines in the recipient skin were measured by flow cytometry and ELISA. During MKTP, melanocytes in the donor skin were quantified by flow cytometry. After MKTP, patients were followed for 12 months and repigmentation was assessed clinically and by ImageJ analysis of clinical photographs. Baseline immunologic biomarkers, duration of clinical stability, and transplanted melanocyte number were correlated to postsurgical repigmentation scores. CD8+ T cells were elevated in 43% of the clinically stable vitiligo lesions. CD8+ T-cell number negatively correlated with postsurgical repigmentation scores (r = -0.635, P = 0.002). Duration of clinical stability, skin chemokines, and transplanted melanocyte number did not influence postsurgical repigmentation. This study demonstrates that CD8+ T-cell number correlates negatively with success of postsurgical repigmentation and can be a biomarker to identify ideal surgical candidates.
