RESUMO

BACKGROUND: Arterial stiffness has been associated with an increased risk of cardiovascular disease (CVD) in some patient populations. OBJECTIVES: The aims of this study were to investigate (1) whether there is an association between arterial stiffness, as measured by the Mobil-O-Graph, and risk for CVD in a population of individuals with intellectual disability and (2) whether arterial stiffness can predict the risk for CVD. METHODS: This cross-sectional study included 58 individuals who participated in wave 4 of the Intellectual Disability Supplement to the Irish Longitudinal Study on Aging (2019-2020). Statistical models were used to address the first aim, whereas machine learning models were used to improve the accuracy of risk predictions in the second aim. RESULTS: Sample characteristics were mean (SD) age of 60.69 (10.48) years, women (62.1%), mild/moderate level of intellectual disability (91.4%), living in community group homes (53.4%), overweight/obese (84.5%), high cholesterol (46.6%), alcohol consumption (48.3%), hypertension (25.9%), diabetes (17.24%), and smokers (3.4%). Mean (SD) pulse wave velocity (arterial stiffness measured by Mobil-O-Graph) was 8.776 (1.6) m/s. Cardiovascular disease risk categories, calculated using SCORE2, were low-to-moderate risk (44.8%), high risk (46.6%), and very high risk (8.6%). Using proportional odds logistic regression, significant associations were found between arterial stiffness, diabetes diagnosis, and CVD risk SCORE2 (P < .001). We also found the Mobil-O-Graph can predict risk of CVD, with prediction accuracy of the proportional odds logistic regression model approximately 60.12% (SE, 3.2%). Machine learning models, k-nearest neighbor, and random forest improved model predictions over and above proportional odds logistic regression at 75.85% and 77.7%, respectively. CONCLUSIONS: Arterial stiffness, as measured by the noninvasive Mobil-O-Graph, can be used to predict risk of CVD in individuals with intellectual disabilities.

RESUMO

BACKGROUND: Psoriasis is an autoimmune disease that affects approximately 100 million people worldwide, and is a disease that can be ameliorated by anti-cytokine treatment. We aimed to compare the efficacy and safety of risankizumab with adalimumab in patients with moderate-to-severe plaque psoriasis. METHODS: IMMvent was a phase 3, randomised, double-blind, active-comparator-controlled trial completed at 66 clinics in 11 countries. Eligible patients were aged 18 years or older with moderate-to-severe chronic plaque psoriasis. Patients were randomly assigned 1:1 using interactive response technology to receive 150 mg risankizumab subcutaneously at weeks 0 and 4 or 80 mg adalimumab subcutaneously at randomisation, then 40 mg at weeks 1, 3, 5, and every other week thereafter during a 16-week double-blind treatment period (part A). For weeks 16-44 (part B), adalimumab intermediate responders were re-randomised 1:1 to continue 40 mg adalimumab or switch to 150 mg risankizumab. In part A, participants and investigators were masked to study treatment. Randomisation was stratified by weight and previous tumour necrosis factor inhibitor exposure. Co-primary endpoints in part A were a 90% improvement from baseline (PASI 90) and a static Physician's Global Assessment (sPGA) score of 0 or 1 at week 16, and for part B was PASI 90 at week 44 (non-responder imputation). Efficacy analyses were done in the intention-to-treat population and safety analyses were done in the safety population (all patients who received at least one dose of study drug or placebo). This study is registered with ClinicalTrials.gov, number NCT02694523. FINDINGS: Between March 31, 2016, and Aug 24, 2017, 605 patients were randomly assigned to receive either risankizumab (n=301, 50%) or adalimumab (n=304, 50%). 294 (98%) of patients in the risankizumab group and 291 (96%) in the adalimumab group completed part A, and 51 (96%) of 53 patients re-randomised to risankizumab and 51 (91%) of 56 patients re-randomised to continue adalimumab completed part B. At week 16, PASI 90 was achieved in 218 (72%) of 301 patients given risankizumab and 144 (47%) of 304 patients given adalimumab (adjusted absolute difference 24·9% [95% CI 17·5-32·4]; p<0·0001), and sPGA scores of 0 or 1 were achieved in 252 (84%) patients given risankizumab and 252 (60%) patients given adalimumab (adjusted absolute difference 23·3% [16·6-30·1]; p<0·0001). In part B, among adalimumab intermediate responders, PASI 90 was achieved by 35 (66%) of 53 patients switched to risankizumab and 12 (21%) of 56 patients continuing adalimumab (adjusted absolute difference 45·0% [28·9-61·1]; p<0·0001) at week 44. Adverse events were reported in 168 (56%) of 301 patients given risankizumab and 179 (57%) of 304 patients given adalimumab in part A, and among adalimumab intermediate responders, adverse events were reported in 40 (75%) of 53 patients who switched to risankizumab and 37 (66%) of 56 patients who continued adalimumab in part B. INTERPRETATION: Risankizumab showed significantly greater efficacy than adalimumab in providing skin clearance in patients with moderate-to-severe plaque psoriasis. No additional safety concerns were identified for patients who switched from adalimumab to risankizumab. Treatment with risankizumab provides flexibility in the long-term treatment of psoriasis.

RESUMO

BACKGROUND: Psoriasis severity categories have been important tools for clinicians to use in treatment decisions as well as to determine eligibility criteria for clinical studies. However, owing to the heterogeneity of severity classifications and their lack of consideration for the impact of psoriasis involvement of special areas or past treatment history, patients may be miscategorized, which can lead to undertreatment of psoriasis. OBJECTIVE: To develop a consensus statement on the classification of psoriasis severity. METHODS: A modified Delphi approach was developed by the International Psoriasis Council to define psoriasis severity. RESULTS: After completion of the exercise, 7 severity definitions were preferentially ranked. This most preferred statement rejects the mild, moderate, and severe categories in favor of a dichotomous definition: Psoriasis patients should be classified as either candidates for topical therapy or candidates for systemic therapy; the latter are patients who meet at least one of the following criteria: (1) body surface area >10%, (2) disease involving special areas, and (3) failure of topical therapy. LIMITATIONS: This effort might have suffered from a lack of representation by all relevant stakeholders, including patients. CONCLUSION: The consensus statement describes 2 categories of psoriasis severity, while accounting for special circumstances where patients may require systemic therapy.

RESUMO

Ixekizumab was efficacious in treating moderate-to-severe genital psoriasis over 12 weeks. We evaluated the long-term efficacy and safety of ixekizumab for up to 52 weeks. Patients were randomized to 80 mg ixekizumab every 2 weeks or to placebo through Week 12, then received 80 mg open-label ixekizumab every 4 weeks through Week 52. In patients initially randomized to ixekizumab, clear or almost clear genital skin was achieved for 73% of patients at Week 12 and 75% at Week 52. Persistent improvements were also observed for overall psoriasis, genital itch, and the impact of genital psoriasis on the frequency of sexual activity. The safety profile was consistent with studies of ixekizumab in patients with moderate-to-severe plaque psoriasis. Ixekizumab provided rapid and persistent improvements in the signs and symptoms of genital psoriasis for up to 52 weeks of treatment.

RESUMO

INTRODUCTION: Genital psoriasis (GenPs) is common and distressing for patients, but is often not discussed with physicians, and no previous clinical trials have assessed the effects of biologics specifically on GenPs and its associated symptoms. AIM: To report results for novel patient-reported outcomes (PROs) for the assessment of symptoms and the sexual impact of GenPs before and after treatment in the IXORA-Q study. METHODS: IXORA-Q (NCT02718898) was a phase III, randomized, double-blind, placebo-controlled study of ixekizumab (80 mg/2 weeks after 160-mg initial dose) vs placebo for GenPs. Men and women ≥18 years old with moderate-to-severe GenPs and body surface area (BSA) ≥1% were assessed through 12 weeks. MAIN OUTCOME MEASURE: GenPs symptoms were assessed using the 8-item Genital Psoriasis Symptoms Scale (GPSS), Genital Psoriasis Sexual Frequency Questionnaire (GenPs-SFQ), and Genital Psoriasis Sexual Impact Scale (GPSIS) (validation data presented in the supplemental materials), and the Dermatology Life Quality Index (DLQI) item 9. RESULTS: For patients receiving ixekizumab (N = 75) vs placebo (N = 74), statistically significant improvement in GenPs symptoms were seen from week 1 onward (GPSS total and individual items, all P < .005). Sexual activity avoidance owing to GenPs symptoms (GPSIS) decreased significantly with ixekizumab from week 4 onward (all P <.005), whereas impact of sexual activity on GenPs improved significantly with ixekizumab at weeks 2-8 (all P < 0.05). Ixekizumab resulted in significant improvement vs placebo by week 1 onward in limitations on frequency of sexual activity owing to GenPs (GenPs-SFQ item 2). Sexual difficulties caused by skin (DLQI item 9) decreased significantly with ixekizumab from week 2 onward (all P < .001). CLINICAL IMPLICATIONS: Both GenPs symptoms and impact on sexual activity improved rapidly and significantly with ixekizumab vs placebo through 12 weeks in patients with moderate-to-severe GenPs and BSA ≥1%. STRENGTH & LIMITATIONS: To our knowledge, this is the first phase III, randomized, placebo-controlled, double-blinded clinical trial to evaluate the effect of any treatment on the symptoms and sexual impact related to GenPs. The study did not include an active comparator owing to the lack of any well-established treatment for moderate-to-severe GenPs, and the period assessed herein was of relatively short duration. CONCLUSION: These validated PRO measures may aid in future clinical studies of GenPs and in facilitating discussions of GenPs symptoms and their impact between patients and clinicians. Yosipovitch G, Foley P, Ryan C. Ixekizumab improved patient-reported genital psoriasis symptoms and impact of symptoms on sexual activity vs placebo in a randomized, double-blind study.

RESUMO

BACKGROUND: There is a significant association between psoriasis and inflammatory bowel disease (IBD). Many treatments for psoriasis and psoriatic arthritis are also used for IBD. OBJECTIVE: To assess therapeutic options for patients with psoriasis and concurrent IBD. METHODS: A systematic literature search was performed for clinical studies of biologic and systemic psoriasis medications in psoriasis, psoriatic arthritis, ulcerative colitis, and Crohn's disease, for the period from January 1, 1947, to February 14, 2017. Randomized, controlled, double-blinded studies were selected if available. If not, the next highest level of available evidence was selected. RESULTS: Of the 2282 articles identified, 132 were selected. Infliximab and adalimumab have demonstrated efficacy in psoriasis, psoriatic arthritis, ulcerative; colitis, and Crohn's disease. Ustekinumab has demonstrated efficacy in psoriasis, psoriatic arthritis, and Crohn's disease. Certolizumab has demonstrated efficacy in psoriatic arthritis and Crohn's disease. Etanercept, secukinumab, brodalumab, and ixekizumab have demonstrated efficacy in psoriasis and psoriatic arthritis but may exacerbate or induce IBD. Guselkumab has demonstrated efficacy in psoriasis. LIMITATIONS: There are no known clinical trials of treatment specifically for concurrent psoriasis and IBD. CONCLUSIONS: Infliximab and adalimumab have demonstrated efficacy in psoriasis, psoriatic arthritis, ulcerative colitis, and Crohn's disease; other agents have demonstrated efficacy for some, but not all, of these indications.

RESUMO

BACKGROUND: An urgent need exists in the United States to establish treatment goals in psoriasis. OBJECTIVE: We aim to establish defined treatment targets toward which clinicians and patients with psoriasis can strive to inform treatment decisions, reduce disease burden, and improve outcomes in practice. METHODS: The National Psoriasis Foundation conducted a consensus-building study among psoriasis experts using the Delphi method. The process consisted of: (1) literature review, (2) pre-Delphi question selection and input from general dermatologists and patients, and (3) 4 Delphi rounds. RESULTS: A total of 25 psoriasis experts participated in the Delphi process. The most preferred instrument was body surface area (BSA). The most preferred time for evaluating patient response after starting new therapies was at 3 months. The acceptable response at 3 months postinitiation was either BSA 3% or less or BSA improvement 75% or more from baseline. The target response at 3 months postinitiation was BSA 1% or less. During the maintenance period, evaluation every 6 months was most preferred. The target response at every 6 months maintenance evaluation is BSA 1% or less. LIMITATIONS: Although BSA is feasible in practice, it does not encompass health-related quality of life, costs, and risks of side effects. CONCLUSION: With defined treatment targets, clinicians and patients can regularly evaluate treatment responses and perform benefit-risk assessments of therapeutic options individualized to the patient.

RESUMO

Psoriasis is a common, immune-mediated genetic disorder of the skin and is associated with arthritis in approximately 30% of cases. Previously, we localized PSORS2 (psoriasis susceptibility locus 2) to chromosomal region 17q25.3-qter after a genome-wide linkage scan in a family of European ancestry with multiple cases of psoriasis and psoriatic arthritis. Linkage to PSORS2 was also observed in a Taiwanese family with multiple psoriasis-affected members. In caspase recruitment domain family, member 14 (CARD14), we identified unique gain-of-function mutations that segregated with psoriasis by using genomic capture and DNA sequencing. The mutations c.349G>A (p.Gly117Ser) (in the family of European descent) and c.349+5G>A (in the Taiwanese family) altered splicing between CARD14 exons 3 and 4. A de novo CARD14 mutation, c.413A>C (p.Glu138Ala), was detected in a child with sporadic, early-onset, generalized pustular psoriasis. CARD14 activates nuclear factor kappa B (NF-kB), and compared with wild-type CARD14, the p.Gly117Ser and p.Glu138Ala substitutions were shown to lead to enhanced NF-kB activation and upregulation of a subset of psoriasis-associated genes in keratinocytes. These genes included chemokine (C-C motif) ligand 20 (CCL20) and interleukin 8 (IL8). CARD14 is localized mainly in the basal and suprabasal layers of healthy skin epidermis, whereas in lesional psoriatic skin, it is reduced in the basal layer and more diffusely upregulated in the suprabasal layers of the epidermis. We propose that, after a triggering event that can include epidermal injury, rare gain-of-function mutations in CARD14 initiate a process that includes inflammatory cell recruitment by keratinocytes. This perpetuates a vicious cycle of epidermal inflammation and regeneration, a cycle which is the hallmark of psoriasis.

RESUMO

BACKGROUND: Genital involvement has significant psychosexual implications for psoriasis patients. OBJECTIVE: This study was designed to ascertain factors associated with the development of genital psoriasis and its impact on quality of life and sexual functioning. METHODS: This was an observational, multicenter study of 354 consecutive psoriasis patients. RESULTS: One hundred thirty-four patients (38%) had current genital involvement while 224 (63%) had a current and/or previous history of genital involvement. Eighty-seven percent reported itch, 39% pain, 42% dyspareunia, 32% a worsening of their genital psoriasis after intercourse, and 43% a decreased frequency of intercourse. Younger age of onset of psoriasis, male sex, more severe disease, and involvement of the scalp, flexures, and nails were associated with the presence of genital disease. There was no association with circumcision or obesity. Patients with genital psoriasis had more impairment in quality of life and sexual health as determined by the Dermatology Life Quality Index (P < .0001), the Center for Epidemiological Studies-Depression Scale (P = .01), and the Relationship and Sexuality Scale (P < .0001). LIMITATIONS: This was a descriptive study from 2 tertiary referral centers where patients were likely to have more severe psoriasis. CONCLUSION: This study highlights the high prevalence of genital psoriasis and its profound impact on quality of life and sexual health.

RESUMO

Over the past 2 decades, considerable progress has been made to further elucidate the complex pathogenesis of psoriasis, facilitating the development of a new armamentarium of more effective, targeted therapies. Despite these important advances, substantial deficits remain in our understanding of psoriasis and its treatment, necessitating further research in many areas. In the sixth section of the American Academy of Dermatology Psoriasis Guidelines of Care, gaps in research and care were identified. We discuss the most important gaps in research that currently exist and make suggestions for studies that should be performed to address these deficits. These encompass both basic science and clinical research studies, including large, prospective epidemiologic studies to determine the true prevalence and natural history of psoriasis; further molecular studies in patients with psoriatic and psoriatic arthritis to understand the function of psoriasis susceptibility genes and to identify novel therapeutic targets; studies to examine the role of environmental factors in the development of psoriasis; further investigation of the relationship between psoriasis and cardiometabolic disease; studies that examine the role of adjunctive therapies such as psychological interventions in appropriate patient groups; and finally, studies to identify biomarkers of disease severity and treatment response to optimize patient therapy.

RESUMO

BACKGROUND: The frequent prescribing of psychotropics and high prevalence of polypharmacy among older adults with intellectual disabilities require close monitoring. AIMS: To describe change in prevalence, predictors and health outcomes of psychotropic use during the four waves (2009/2010, 2013/2014, 2016/2017, 2019/2020) of the Intellectual Disability Supplement to the Irish Longitudinal Study on Ageing (IDS-TILDA). METHOD: Eligible participants were adults (≥40 years) with intellectual disabilities who participated in all four waves of IDS-TILDA and who reported medication use for the entire period. Differences between groups were tested using Cochran's Q test for binary variables and the McNemar-Bowker test for variables with more than two categories. Generalised estimating equation models were used to assess associations between psychotropic use, participants' characteristics and health outcomes. RESULTS: Across waves (433 participants) there were no significant differences in prevalence of psychotropic use (61.2-64.2%) and psychotropic polypharmacy (42.7-38.3%). Antipsychotics were the most used subgroup, without significant change in prevalence between waves (47.6-44.6%). A significant decrease was observed for anxiolytics (26.8-17.6%; P < 0.001) and hypnotics/sedatives (14.1-9.0%; P < 0.05). A significant increase was recorded for antidepressants (28.6-35.8%; P < 0.001) and mood-stabilising agents (11.5-14.6%; P < 0.05). Psychotropic polypharmacy (≥2 psychotropics) was significantly associated with moderate to total dependence in performing activities of daily living over the 10-year period (OR = 1.80, 95% CI 1.21-2.69; P < 0.05). CONCLUSIONS: The study indicates an increase in usage of some classes of psychotropic, a reduction in others and no change in the relatively high rate of antipsychotic use over 10 years in a cohort of older adults with intellectual disabilities and consequent risk of psychotropic polypharmacy and medication-related harm.

RESUMO

The preconditioning response conferred by a mild uncoupling of the mitochondrial membrane potential (Δψ(m)) has been attributed to altered reactive oxygen species (ROS) production and mitochondrial Ca(2+) uptake within the cells. Here we have explored if altered cellular energetics in response to a mild mitochondrial uncoupling stimulus may also contribute to the protection. The addition of 100 nM FCCP for 30 min to cerebellar granule neurons (CGNs) induced a transient depolarization of the Δψ(m), that was sufficient to significantly reduce CGN vulnerability to the excitotoxic stimulus, glutamate. On investigation, the mild mitochondrial 'uncoupling' stimulus resulted in a significant increase in the plasma membrane levels of the glucose transporter isoform 3, with a hyperpolarisation of Δψ(m) and increased cellular ATP levels also evident following the washout of FCCP. Furthermore, the phosphorylation state of AMP-activated protein kinase (AMPK) (Thr 172) was increased within 5 min of the uncoupling stimulus and elevated up to 1h after washout. Significantly, the physiological changes and protection evident after the mild uncoupling stimulus were lost in CGNs when AMPK activity was inhibited. This study identifies an additional mechanism through which protection is mediated upon mild mitochondrial uncoupling: it implicates increased AMPK signalling and an adaptive shift in energy metabolism as mediators of the preconditioning response associated with FCCP-induced mild mitochondrial uncoupling.

RESUMO

Psoriasis is a chronic and complex inflammatory skin disease with lesions displaying dramatically altered mRNA expression profiles. However, much less is known about the expression of small RNAs. Here, we describe a comprehensive analysis of the normal and psoriatic skin miRNAome with next-generation sequencing in a large patient cohort. We generated 6.7 × 10(8) small RNA reads representing 717 known and 284 putative novel microRNAs (miRNAs). We also observed widespread expression of isomiRs and miRNA*s derived from known and novel miRNA loci, and a low frequency of miRNA editing in normal and psoriatic skin. The expression and processing of selected novel miRNAs were confirmed with qRT-PCR in skin and other human tissues or cell lines. Eighty known and 18 novel miRNAs were 2-42-fold differentially expressed in psoriatic skin. Of particular significance was the 2.7-fold upregulation of a validated novel miRNA derived from the antisense strand of the miR-203 locus, which plays a role in epithelial differentiation. Other differentially expressed miRNAs included hematopoietic-specific miRNAs such as miR-142-3p and miR-223/223*, and angiogenic miRNAs such as miR-21, miR-378, miR-100 and miR-31, which was the most highly upregulated miRNA in psoriatic skin. The functions of these miRNAs are consistent with the inflammatory and hyperproliferative phenotype of psoriatic lesions. In situ hybridization of differentially expressed miRNAs revealed stratified epidermal expression of an uncharacterized keratinocyte-derived miRNA, miR-135b, as well as the epidermal infiltration of the hematopoietic-specific miRNA, miR-142-3p, in psoriatic lesions. This study lays a critical framework for functional characterization of miRNAs in healthy and diseased skin.

RESUMO

The intermittent use of dilute sodium hypochlorite "bleach baths" has shown efficacy as adjunctive therapy for atopic dermatitis (AD). This feasibility study evaluated the clinical response and patient acceptability of treatment with a cleansing body wash containing sodium hypochlorite in children with AD. This was a 12-week open-label feasibility study of 18 children with AD conducted in a pediatric dermatology outpatient clinic between May 2011 and July 2012. Children with moderate to severe AD, defined as an Investigator Global Assessment (IGA) score of at least 3 on a 5-point scale, who were age 6 months and older and had lesional cultures positive for Staphylococcus aureus at baseline were included. Patients were instructed to wash 3 days/week for 12 weeks with the sodium hypochlorite-containing cleansing body wash. During the study period, patient's individualized topical and systemic treatment regimens were continued. Clinical response to treatment was measured using an IGA score and the percentage of body surface area (BSA) affected. Parents were also administered a retrospective questionnaire evaluating acceptability of the product. There was a statistically significant reduction in IGA score at all time points, with an overall mean reduction from baseline to final measurement using the last observation carried forward in all patients of 1.0 (p = 0.001, n = 18). Similarly the mean reduction of BSA affected was 14.8% (p = 0.005, n = 18). Parents reported that the body wash was significantly easier to use than traditional bleach baths (p < 0.001). The significant reductions in clinical disease severity scores with use of this formulation are encouraging.

RESUMO

Psoriasis is a common, chronic, inflammatory, multisystem disease with predominantly skin and joint manifestations affecting approximately 2% of the population. In the first 5 parts of the American Academy of Dermatology Psoriasis Guidelines of Care, we have presented evidence supporting the use of topical treatments, phototherapy, traditional systemic agents, and biological therapies for patients with psoriasis and psoriatic arthritis. In this sixth and final section of the Psoriasis Guidelines of Care, we will present cases to illustrate how to practically use these guidelines in specific clinical scenarios. We will describe the approach to treating patients with psoriasis across the entire spectrum of this fascinating disease from mild to moderate to severe, with and without psoriatic arthritis, based on the 5 prior published guidelines. Although specific therapeutic recommendations are given for each of the cases presented, it is important that treatment be tailored to meet individual patients' needs. In addition, we will update the prior 5 guidelines and address gaps in research and care that currently exist, while making suggestions for further studies that could be performed to help address these limitations in our knowledge base.

RESUMO

CONTEXT: Ustekinumab and briakinumab, monoclonal antibodies to the shared p40 subunit of interleukin (IL)-12 and IL-23, have shown efficacy in treating chronic plaque psoriasis (CPP). Preliminary reports of major adverse cardiovascular events (MACEs) in psoriasis patients receiving anti-IL-12/23 agents have prompted concern. OBJECTIVE: To evaluate a possible association between biologic therapies for CPP and MACEs via meta-analysis. DATA SOURCES: Randomized controlled trials (RCTs) of anti-IL-12/23 (ustekinumab and briakinumab) agents and anti-tumor necrosis factor α (TNF-α) agents (adalimumab, etanercept, and infliximab) used in treating CPP were reviewed using the Cochrane Central Register of Controlled Trials, ClinicalTrials.gov, and Ovid MEDLINE from database inception to May 2011. The results of registered nonpublished completed studies were procured through abstract publications or poster presentations. STUDY SELECTION: Randomized, placebo-controlled, double-blind, monotherapy studies (with safety outcome data for MACE) of IL-12/23 antibodies and anti-TNF-α agents in adults. Studies of psoriatic arthritis were excluded. DATA EXTRACTION: Two investigators independently searched data while 6 investigators reviewed the abstracted data. RESULTS: A total of 22 RCTs comprising 10 183 patients met the predefined inclusion criteria. The primary outcome measure was MACE, a composite end point of myocardial infarction, cerebrovascular accident, or cardiovascular death during the placebo-controlled phase of treatment in patients receiving at least 1 dose of study agent or placebo. Absolute risk differences were used as an effect measure. There was no evidence of statistical heterogeneity across the studies using the I(2) statistic (I(2) = 0), allowing for combination of trial results using the Mantel-Haenszel fixed-effects method. During the placebo-controlled phases of the anti-IL-12/23 studies, 10 of 3179 patients receiving anti-IL-12/23 therapies experienced MACEs compared with zero events in 1474 patients receiving placebo (Mantel-Haenszel risk difference, 0.012 events/person-year; 95% confidence interval [CI], -0.001 to 0.026; P =.12). In the anti-TNF-α trials, only 1 of 3858 patients receiving anti-TNF-α agents experienced a MACE compared with 1 of 1812 patients receiving placebo (Mantel-Haenszel risk difference, -0.0005 events/person-year; 95% CI, -0.010 to 0.009; P = .94). CONCLUSIONS: Compared with placebo, there was no significant difference in the rate of MACEs observed in patients receiving anti-IL-12/IL-23 antibodies or anti-TNF-α treatments. This study may have been underpowered to identify a significant difference.

RESUMO

BACKGROUND: The burden of illness associated with atopic dermatitis (AD) is significant and multidimensional, especially in those with moderate to severe disease. OBJECTIVE: Our objective was to evaluate the disease burden of patients with AD in relation to psychological distress, sleep disturbance, and alcohol misuse. METHODS: Patients with AD, attending 2 tertiary referral centers in Dublin, Ireland, were recruited. A series of validated questionnaires were used including the Patient-Oriented Eczema Measure, Dermatology Life Quality Index (DLQI), Center for Epidemiologic Studies-Depression Scale, Quality of Life in Atopic Dermatitis Questionnaire, Alcohol Use Disorders Identification Test, and Pittsburgh Sleep Quality Index. The Eczema Area and Severity Index was calculated contemporaneously with the questionnaire completion. RESULTS: One hundred patients completed the questionnaire, of whom 52% were female. Sixty-three percent of patients experienced impaired quality of life as measured by the DLQI. Higher DLQI scores correlated with decreasing age (r = 0.3277, P < 0.0009). Thirty percent were found to be at risk of clinical depression, and higher Center for Epidemiologic Studies-Depression Scale scores correlated with a younger age and eczema severity. Sleep disturbance was greater in those at risk of depression (mean = 10.40 vs 5.79, P < 0.0001). Patients with moderate to severe AD were more likely to score higher on the Alcohol Use Disorders Identification Test, and 25% met the criteria for alcohol use disorder. In relation to sleep, 73% of patients scored higher than 5 on the Pittsburgh Sleep Quality Index, which signifies poor sleep quality. CONCLUSIONS: Patients with AD endure a significant burden on health with regard to mental well-being, alcohol use, and sleep quality. Clinicians should consider screening patients for these comorbidities.

RESUMO

UNLABELLED: Cyclosporine is a calcineurin inhibitor that acts selectively on T cells. It has been used in dermatology since 1997 for its US Food and Drug Administration indication of psoriasis and off-label for various other inflammatory skin conditions, including atopic dermatitis, blistering disorders, and connective tissue diseases. In the last decade, many dermatologists have hesitated to use this important drug in their clinical practices because of its toxicity profile. The purpose of this article is to review the mechanism of action of cyclosporine and its current uses and dosing schedules. It is our goal to create a framework in which dermatologists feel comfortable and safe incorporating cyclosporine into their prescribing regimens. LEARNING OBJECTIVES: After completing this learning activity, participants should be able to describe the mechanism of action of cyclosporine, recognize the potential role of cyclosporine in dermatology and the evidence to support this role, and incorporate cyclosporine into his or her prescribing regimens.
