Improvement of health-related quality of life and adherence to treatment with calcipotriol-betamethasone dipropionate gel in patients with psoriasis vulgaris

Determinants of medication adherence in patients with diabetes, hypertension, and hyperlipidemia

OBJECTIVES

To investigate medication non-adherence and its determinants in diabetes, hypertension, and hyperlipidemia.

METHODS

In a multicenter, cross-sectional, non-interventional study, 518 diabetic, 721 hypertensive, and 463 hyperlipidemic patients were recruited, using consecutive sampling, in Greece during the COVID-19 pandemic. Medication adherence was measured with the Adherence to Refills and Medications Scale (ARMS). Multiple linear regressions with robust standard errors investigated the predictors of the ARMS summary score.

RESULTS

Perfect adherence was estimated at 16%, 12%, and 11%, and low adherence at 38.8%, 61.3%, and 66.7% in diabetes, hypertension, and hyperlipidemia, respectively. The factors that significantly increased the likelihood of non-adherence were the following: (a) lower age, female gender, no public health insurance, high perceived threat of illness, low satisfaction with physician consultations, shorter consultations, bad general health, fewer comorbidities, and type 2 diabetes; (b) male gender, not being married, low education, no public insurance, smoking, frequent drinking, shorter consultations, self-perceived inadequacy of knowledge, negative views of medication, presence of comorbidities, fewer medicines being used, and high blood pressure in hypertension; and (c) lower age, not being employed, smoking, frequent drinking, no public insurance, low satisfaction with consultations, negative views of medication, taking 3-4 medicines, high LDL, and low HDL and triglyceride levels in hyperlipidemia. Different curvilinear associations of adherence with BMI and exercise were also found.

CONCLUSION

Medication non-adherence is very common in diabetes, hypertension, and hyperlipidemia. Strategies to improve adherence should consider the different determinants of non-adherence among patient groups.

Metabolic coordination between skin epithelium and type 17 immunity sustains chronic skin inflammation

Inflammatory epithelial diseases are spurred by the concomitant dysregulation of immune and epithelial cells. How these two dysregulated cellular compartments simultaneously sustain their heightened metabolic demands is unclear. Single-cell and spatial transcriptomics (ST), along with immunofluorescence, revealed that hypoxia-inducible factor 1α (HIF1α), downstream of IL-17 signaling, drove psoriatic epithelial remodeling. Blocking HIF1α in human psoriatic lesions ex vivo impaired glycolysis and phenocopied anti-IL-17 therapy. In a murine model of skin inflammation, epidermal-specific loss of HIF1α or its target gene, glucose transporter 1, ameliorated epidermal, immune, vascular, and neuronal pathology. Mechanistically, glycolysis autonomously fueled epithelial pathology and enhanced lactate production, which augmented the γδ T17 cell response. RORγt-driven genetic deletion or pharmacological inhibition of either lactate-producing enzymes or lactate transporters attenuated epithelial pathology and IL-17A expression in vivo. Our findings identify a metabolic hierarchy between epithelial and immune compartments and the consequent coordination of metabolic processes that sustain inflammatory disease.

Integrative Approaches to Sleep Management in Skin Disease: Systematic Review

BACKGROUND

Dermatological conditions, especially when severe, can lead to sleep disturbances that affect a patient's quality of life. However, limited research exists on the efficacy of treatments for improving sleep parameters in skin conditions.

OBJECTIVE

The objective was to perform a systematic review of the literature on dermatological conditions and the treatments available for improving sleep parameters.

METHODS

A literature review was performed using the PubMed, Ovid MEDLINE, Embase, Cochrane, and ClinicalTrials.gov databases from 1945 to 2021. After filtering based on our exclusion criteria, studies were graded using the SORT (Strength of Recommendation Taxonomy) algorithm, and only those receiving a grade of "2" or better were included.

RESULTS

In total, 25 treatment studies (n=11,025) assessing sleep parameters related to dermatological conditions were found. Dupilumab appeared to be the best-supported and most effective treatment for improving sleep in atopic dermatitis (AD) but had frequent adverse effects. Topical treatments for AD were mostly ineffective, but procedural treatments showed some promise. Treatments for other conditions appeared efficacious.

CONCLUSIONS

The evaluation of sleep parameter changes in dermatological treatments is predominantly restricted to AD. Systemic interventions such as dupilumab and procedural interventions were the most efficacious. Sleep changes in other dermatoses were limited by a paucity of available studies. The inclusion of a sleep assessment component to a broader range of dermatological treatment studies is warranted.

Association between medication adherence and health-related quality of life of patients with diabetes

PURPOSE

The purpose was to evaluate the association between medication adherence and health-related quality of life (HRQoL) of patients with diabetes.

METHODS

In this cross-sectional study, a total of 518 patients were recruited from the outpatient departments of different general public and private hospitals in Greece during the COVID-19 pandemic using a consecutive sampling method. HRQoL was assessed with the EQ-5D-5L instrument and medication adherence with the corresponding subscale of the Adherence Starts with Knowledge 20 questionnaire. The relationship between HRQoL and adherence was explored by employing Spearman's correlations and multiple binary logistic and linear stepwise regressions using robust standard errors.

RESULTS

A total of 15.1 and 1.9% of the patients reported that they had taken a medicine either more or less often than prescribed in the last month and week, respectively. Statistically significant but modest correlations of medication non-adherence with the EQ-5D index (rho =  - 0.223), EQ-VAS (rho =  - 0.230), and all the HRQoL domains (rho ranging from 0.211, for pain/discomfort, to 0.136, for mobility issues) were found. These significant associations persisted even after controlling for several other known potential factors of HRQoL in the multivariable analyses, except for the mobility and anxiety/depression dimensions.

CONCLUSION

Medication non-adherence appears to be independently associated with lower HRQoL and health levels in patients with diabetes. It is crucial to plan interventions to enhance medication adherence not only to obtain greater value from the available resources, but also to improve HRQoL of patients with diabetes.

Nocturnal pruritus and sleep disturbance associated with dermatologic disorders in adult patients

Nocturnal pruritus (NP) is a relatively common reason for dermatologic consultation. Its pathophysiology is partially understood. Skin conditions such as atopic dermatitis, psoriasis, urticaria, and prurigo nodularis are well-described causes of NP. The most distressing sequela of NP is sleep deficit, which can lead to physical and mental disturbances (e.g., daytime somnolence and fatigue) and negative emotional states that profoundly affect quality of life. However, this aspect of NP is often overlooked by dermatologists. It is essential to assess sleep quality in such patients and adopt appropriate measures to arrest the problem at an early stage. We conducted an evidence-based literature review to highlight the pathogenetic mechanisms of NP, identify dermatologic etiologies, and explore methods that have been used to assess the quality of sleep. Furthermore, we performed a systematic review of studies on sleep disturbance relevant to NP in patients with dermatologic conditions. Finally, we discuss the evidence on treatment options for NP and indicate therapies that may target both NP and sleep disturbance.

General practice recommendations for the topical treatment of psoriasis: a modified-Delphi approach

BACKGROUND

Although GPs are usually the first port of call for patients with psoriasis, there is a lack of consistent and up-to-date clinical recommendations for interventions for patients with mild-to-moderate disease.

AIM

To provide practical recommendations for GPs to optimise psoriasis treatment with topical therapies in four key areas: patient identification; treatment decision making with topical theory; topical treatment outcomes; and optimising patient adherence.

DESIGN & SETTING

A consensus-seeking programme (modified-Delphi approach) was undertaken to assess the literature and develop recommendations for GPs, based on evidence and expert opinion.

METHOD

Three dermatologists compiled 47 questions that were subsequently ranked and refined according to clinical relevance or importance using an online survey. Thereafter, 19 dermatologists from different European countries developed statements and clinical recommendations for the top seven ranked topical treatment and GP-relevant questions based on literature research and clinical experience. The final recommendations were based on 100% agreement among a final panel of seven experts.

RESULTS

The clinical effectiveness, fast onset of action, tolerability, cosmetic acceptability, and practicability of topical therapy, in addition to good physician-patient communication, are important for optimising patient adherence and maximising efficacy. Topical treatments combining corticosteroids and vitamin D analogues (administered as fixed combination) are well-established first-line treatments in mild-to-moderate psoriasis.

CONCLUSION

Simple but detailed practical guidance is provided, which is formed from evidence and expert clinical recommendations, to assist GPs with the optimal use of topical agents based on efficacy, tolerability, disease severity, site of psoriasis, patient lifestyle and preferences, and intended duration of treatment.

Transcriptome Profiling Analyses in Psoriasis: A Dynamic Contribution of Keratinocytes to the Pathogenesis

Psoriasis is an immune-mediated inflammatory skin disease with a complex etiology involving environmental and genetic factors. A better insight into related genomic alteration helps design precise therapies leading to better treatment outcome. Gene expression in psoriasis can provide relevant information about the altered expression of mRNA transcripts, thus giving new insights into the disease onset. Techniques for transcriptome analyses, such as microarray and RNA sequencing (RNA-seq), are relevant tools for the discovery of new biomarkers as well as new therapeutic targets. This review summarizes the findings related to the contribution of keratinocytes in the pathogenesis of psoriasis by an in-depth review of studies that have examined psoriatic transcriptomes in the past years. It also provides valuable information on reconstructed 3D psoriatic skin models using cells isolated from psoriatic patients for transcriptomic studies.

Patients' and Doctors' Beliefs about Treatment and Long-Term Adherence in Rheumatic Diseases

Objective:

The aim of this study was to explore the beliefs of rheumatologists and patients about treatment-related factors, long-term adherence, and their communication with regard to rheumatic diseases.

Methods:

In a multicentre, observational study conducted in Greece, a structured questionnaire was administered to 75 rheumatologists and 398 rheumatic patients from different regions. Five domains were investigated: i) effectiveness of treatment, ii) choice of treatment, iii) change of ineffective treatment, iv) long-term adherence, and v) the quality of communication between doctors and patients. Descriptive data, confidence intervals, t-tests and factor analysis were employed.

Results:

Examining the patients’ and rheumatologists’ beliefs and attitudes about treatment profiles and long-term adherence, a statistically significant convergence in their views on effectiveness and safety as the predominant factors concerning choice of treatment and long-term adherence was found. Although patients reported high trust to their doctors, a divergence of views is recorded regarding communication of the two parts. Statistically significant differences in the views between patients and rheumatologists were found with regards to access (p<0.001), time per visit (p<0.001), mutual understanding (p<0.001), and overall communication (p<0.001).

Conclusions:

Our study shows a great rate of agreement between patients and rheumatologists regarding the factors determining the efficacy, choice, switching and adherence to treatment while there was significant divergence in the views regarding the quality of communication between the two parts. Co-ordinated efforts are needed in order to improve the communication level between rheumatic patients and rheumatologists.

Calcipotriol/betamethasone dipropionate formulations for psoriasis: an overview of the options and efficacy data

INTRODUCTION

Psoriasis is a very common chronic inflammatory skin disease affecting up to 3% of the general population with 75% of the psoriasis subjects being affected by a mild form of disease. Hence, topical therapy is the most frequent employed treatment in psoriasis also because it can be easily combined with systemic therapy. In this context, calcipotriol/betamethasone dipropionate (Cal/BD) fixed-dose association represents the first-line treatment due to its efficacy and once-daily application. Different Cal/BD formulations, such as ointment, gel (topical suspension), and aerosol foam, are approved by US Food and Drug Administration.

AREAS COVERED

For this review, relevant English literature (trials, real-life studies, case series, and reviews) regarding Cal/BD different formulations efficacy in psoriasis was searched for through to 28 January 2020. The following database were consulted: PubMed, Embase, the Cochrane Library, Google Scholar, EBSCO, and clinicaltrials.gov.

EXPERT OPINION

Cal/BD formulations are efficacious treatment for psoriasis. Cal/BD aerosol foam shows a higher efficacy compared to Cal/BD ointment or gel formulations, appearing as a game-changer in psoriasis therapy not only for mild disease but also for moderate psoriasis as well as in selected severe cases in combination with systemic treatments.

Genomic alterations driving psoriasis pathogenesis

Psoriasis is an immune mediated inflammatory skin disease with complex etiology involving interplay between environmental and genetic risk factors as disease initiating event. Enhanced understanding on genetic risk factors, differentially expressed genes, deregulated proteins and pathway-targeted therapeutics have established multiple axis of psoriasis pathogenesis. So far, loci in 424 genes are reported to be associated with psoriasis alongside copy number variations and epigenetic alterations. From clinical perspective, presence of specific genetic trigger(s) in individual psoriasis patient could aid in devising a personalized therapeutic strategy. Therefore, the review presents an updates on reported genomic alterations and their subsequent course of cutaneous inflammations that potentially drive to psoriasis.

Itching at night: A review on reducing nocturnal pruritus in children

The most common causes of chronic nocturnal itching in children are atopic dermatitis and psoriasis, with lichen simplex chronicus and prurigo nodularis contributing to lesser degrees. Despite the prevalence of nocturnal itching, its pathophysiology remains poorly understood. The most troubling consequence of itching at night is poor quality of sleep. Poor sleep quality in children with nocturnal itching has been linked to adverse neurocognitive, behavioral, and physiologic outcomes, including poor performance in school, attention deficit hyperactivity disorder, short stature, hypertension, obesity, and impaired immune function. There is no consensus on the best management of nocturnal itching in children. We conducted a review of the literature evaluating the efficacy of various treatment options for children with chronic nocturnal pruritus. Our review found three recently conducted randomized controlled trials and one case report demonstrating the efficacy of topical corticosteroids, oral melatonin, and clonidine in reducing nocturnal itching or improving sleep quality in children with nocturnal pruritus. Future research is needed to elucidate the pathophysiology of nocturnal itching to best develop targeted, effective treatment strategies.

Asian consensus on assessment and management of mild to moderate plaque psoriasis with topical therapy

A working group of dermatologists in Asian countries assessed the current status of psoriatic management in the region to prepare a consensus report on topical treatment in mild to moderate plaque psoriasis. Even though the association of psoriasis with systemic comorbidities is increasingly acknowledged, psoriasis is still lower in health‐care priority lists in the region. The psychosocial impact of psoriasis may be greater in Asian countries due to cultural norms and social discrimination. Non‐adherence to treatment is also common among Asians. The current care given to patients with mild to moderate psoriasis needs to be streamlined, enhanced and organized with a patient‐centered care approach to achieve better outcomes. A comprehensive assessment of the disease severity and its impact on a patient's life is required before initiating treatment. Education and active involvement of the patient in the treatment plan is an important part of psoriatic management. It is recommended to personalize topical treatment to meet the needs of the patient, depending on disease severity, psychosocial impact, the patient's expectations and, more importantly, the patient's willingness and ability to actively follow the treatment procedure. Fixed‐dose combination of corticosteroid and vitamin D analogs is the preferred topical medication for both initial and maintenance phases of treatment. The fast containment of the disease is the goal of the initial phase of 4–8 weeks and it demands a potent fast‐acting topical therapy. Satisfactory control of the disease and prevention of relapses should be achieved during the maintenance phase with twice a week or weekend applications.

The cost–effectiveness of blue-light therapy in the treatment of mild-to-moderate psoriasis

Aim: To investigate the cost–effectiveness of blue-light therapy versus a two-compound formulation (TCF) (Dovobet® gel [calcipotriol and betamethasone]) in mild-to-moderate psoriasis. Methods: A Markov model was applied to describe the course of disease among Dutch patients with a Psoriasis Area and Severity Index (PASI) score ≤ 10 over a 52-week time horizon. Patients received either 12-week blue-light therapy or two 4-week treatments with TCF. Patients, experiencing no PASI reduction after either therapy, were assumed to receive 12-week ultraviolet B phototherapy. Results: There was no significant difference in PASI reduction between two interventions (71 vs 72%). However, blue-light therapy was associated with a cost savings of EU€248. Conclusion: Treatment of mild-to-moderate chronic plaque psoriasis using blue-light therapy may be more cost-effective than TCF.
