A study of the safety and efficacy of calcipotriol and betamethasone dipropionate scalp formulation in the long-term management of scalp psoriasis

Health-related quality of life and its determinants among patients with psoriasis at a referral hospital in Northwest Ethiopia

Objectives

This study assessed health-related quality of life (HRQoL) and its determinants among patients with psoriasis having follow-ups at the University of Gondar Comprehensive Specialized Hospital (UoGCSH).

Design setting and participants

A cross-sectional institutional-based study was conducted at the dermatologic clinic of UoGCSH from June to August 2022. Four hundred eligible patients with psoriasis were included in the study using a systematic random sampling technique.

The main outcome measured

The Dermatology Life Quality Index (DLQI) measurement scale was used to assess HRQoL. The relationship between HRQoL and independent predictor variables was investigated using bivariable and multivariate logistic regression analyses. Statistical significance was defined as a p-value of <0.05 at the 95% CI.

Results

Of the 422 study subjects approached, 400 respondents with psoriasis were included in the final analysis. The mean (±SD) age was 39.8 (±17.2) years, and 56% were women. The most commonly prescribed medications were topical corticosteroids (68.3 %). The mean (±SD) DLQI was 13.05 (7.82). More than three-fourths (78.5%) of the patients' HRQOL was affected, and its severity ranged from very large to extremely large. Being male (adjusted odd ratio) (AOR) = 0.373, 95% CI (0.171, 0.773), the use of alternative therapy (AOR) = 0.237, 95% CI (0.114, 0.494), duration of diseases (AOR) = 0.184, 95% CI (0.061, 0.557), duration on medication (AOR) =3.75, 95% CI (1.32, 10.73), presence of comorbidity (AOR) = 6.199, 95% CI (1.921, 20.00), and income were found to have a significant association with poor HRQoL.

Conclusion

Psoriasis patients had reduced HRQoL, which was lower than that of the normal population. The study identified that several variables contributed to this reduced HRQoL. Predictors that take into account interventions were essential for preserving patients' HRQoL.

Efficacy of Calcipotriol/Betamethasone Dipropionate Fixed-Combination Aerosol Foam in the Treatment of Localized Scalp Psoriasis: A Real-Life Case Series from Switzerland

Introduction

Scalp psoriasis is one of the most common and challenging manifestations of plaque psoriasis for general practitioners, dermatologists, and patients, as successful topical management requires the choice of effective ingredients, an appropriate formulation, and clear application instructions to patients. To date, only limited experience is available for the calcipotriol (50 μg/g)/betamethasone dipropionate (0.5 mg/g) aerosol foam formulation (Cal/BD foam) in the treatment of scalp psoriasis.

Methods

In this Swiss real-world patient case series, we asked 10 consecutive patients with active scalp psoriasis to apply the Cal/BD foam once daily before bedtime for a period of 4 weeks. Clear application and rinse-off instructions were provided.

Results

A total of 10 consecutive adult patients were treated between April and May 2019. Two patients suffered from mild, five from moderate, and three from severe scalp psoriasis. In eight out of the 10 patients, scalp psoriasis was the only manifestation of disease. All patients had received previous topical treatments, mainly topical corticosteroids (TCS), tar shampoo, and salicylic acid. After 4 weeks of treatment with Cal/BD foam, the scalp psoriasis improved in all 10 patients by ≥ 2 points on a 5-point severity assessment scale. Eight out of 10 patients achieved clear/almost clear skin after 4 weeks of treatment, with no further keratolytic treatments needed. Adverse events were not observed in any of the patients. Overall, patients were very satisfied with the ease of use, the efficacy, and the safety of the Cal/BD foam.

Conclusion

Our case series confirms that Cal/BD foam is a rapid, effective, and convenient treatment for localized scalp psoriasis in a nonselected real-world patient cohort refractory to TCS or other local treatments. Clear application instructions are crucial for treatment success and cosmetic acceptance, however.

Proactive therapy: new perspectives for long-term topical treatment of psoriasis

Mild to moderate psoriasis is most often treated with topical therapy. The article reviews literature on topical treatments that have been assessed in clinical trials and real-life studies lasting at least 12 months. Calcipotriol/bethamethasone dipropionate foam in maintenance treatment following the induction phase can improve efficacy and safety of topical therapy in psoriatic patients. Introduction of new topical nonsteroidal drugs and the wider use of proactive therapy seem to be crucial to achieve satisfactory long-term outcomes in psoriasis.

Emerging paradigm shift toward proactive topical treatment of psoriasis: A narrative review

Psoriasis (PsO) requires safe and effective long‐term management to reduce the risk of recurrence and decrease the frequency of relapse. Topical PsO therapies are a cornerstone in the management of PsO though safety concerns limit the chronic, continuous use of topical corticosteroids and/or vitamin D₃ analogs. Evidence‐based guidelines on optimal treatment targets and maintenance therapy regimens are currently lacking. This review explores the evidence supporting approaches to maintenance topical therapy for PsO including continuous long‐term therapy, chronic intermittent use, step‐down therapy, sequential or pulse therapy regimens, and proactive maintenance therapy. Several unaddressed questions are discussed including how and when to transition from acute to maintenance therapy, strategies for monitoring long‐term treatment, the role of topical maintenance therapy in the context of systemic and biologic therapies, risks of maintenance therapy, prescribing a topical preparation suitable for patients' preferences and skin type, and key concepts for patient education to maximize long‐term outcomes. Overall, emerging evidence supports a paradigm shift toward proactive treatment once skin is completely clear as a strategy to enhance disease control without compromising safety.

Efficacy and safety of apremilast in patients with mild-to-moderate plaque psoriasis: Results of a phase 3, multicenter, randomized, double-blind, placebo-controlled trial

BACKGROUND

Patients with mild-to-moderate psoriasis may have substantial quality-of-life impairment.

OBJECTIVE

To evaluate apremilast 30 mg twice daily for mild-to-moderate psoriasis.

METHODS

Phase 3, double-blind, placebo-controlled study in adults with mild-to-moderate psoriasis inadequately controlled or intolerant to ≥ 1 topical psoriasis therapy (NCT03721172). The primary endpoint was the achievement of static Physician Global Assessment score of 0 (clear) or 1 (almost clear) and ≥ 2-point reduction at week 16.

RESULTS

Five hundred ninety-five patients were randomized (apremilast: 297; placebo: 298). The primary endpoint was met, with a significantly greater static Physician Global Assessment response rate observed at week 16 in the apremilast group compared with the placebo group (21.6% vs 4.1%; P < .0001). All secondary endpoints were met with the achievement of body surface area-75 (33.0% vs 7.4%), body surface area ≤ 3% (61.0% vs 22.9%), ≥ 4-point reduction in Whole Body Itch Numeric Rating Scale (43.2% vs 18.6%), Scalp Physician Global Assessment 0 or 1 and ≥ 2-point reduction (44.0% vs 16.6 %), and changes from baseline in body surface area, Psoriasis Area and Severity Index, and Dermatology Life Quality Index (all P < .0001). The most commonly reported adverse events (≥ 5%) with apremilast were diarrhea, headache, nausea, nasopharyngitis, and upper respiratory tract infection, consistent with prior studies.

LIMITATIONS

The study lacked an active-comparator arm.

CONCLUSION

Apremilast demonstrated efficacy in mild-to-moderate psoriasis and safety consistent with the established safety profile of apremilast.

Nanoemulsions: A Review on the Conceptualization of Treatment for Psoriasis Using a 'Green' Surfactant with Low-Energy Emulsification Method

Psoriasis is a skin disease that is not lethal and does not spread through bodily contact. However, this seemingly harmless condition can lead to a loss of confidence and social stigmatization due to a persons' flawed appearance. The conventional methods of psoriasis treatment include taking in systemic drugs to inhibit immunoresponses within the body or applying topical drugs onto the surface of the skin to inhibit cell proliferation. Topical methods are favored as they pose lesser side effects compared to the systemic methods. However, the side effects from systemic drugs and low bioavailability of topical drugs are the limitations to the treatment. The use of nanotechnology in this field has enhanced drug loading capacity and reduced dosage size. In this review, biosurfactants were introduced as a 'greener' alternative to their synthetic counterparts. Glycolipid biosurfactants are specifically suited for anti-psoriatic application due to their characteristic skin-enhancing qualities. The selection of a suitable oil phase can also contribute to the anti-psoriatic effect as some oils have skin-healing properties. The review covers the pathogenic pathway of psoriasis, conventional treatments, and prospective ingredients to be used as components in the nanoemulsion formulation. Furthermore, an insight into the state-of-the-art methods used in formulating nanoemulsions and their progression to low-energy methods are also elaborated in detail.

Systematic review and practical guidance on the use of topical calcipotriol and topical calcipotriol with betamethasone dipropionate as long-term therapy for mild-to-moderate plaque psoriasis

While many patients with psoriasis are candidates for topical agents, long-term treatment effects are unclear. This systematic review evaluated global findings from clinical trials and real-world studies of topical calcipotriol and the two-compound formulation of calcipotriol and betamethasone dipropionate for mild-to-moderate plaque psoriasis (including scalp psoriasis). PubMed, Embase and MEDLINE were searched for relevant English-language publications along with Chinese, Japanese, Korean and Latin American publication databases. Identified articles were screened by title and abstract against predefined inclusion/exclusion criteria. A narrative synthesis of key efficacy and safety findings from the full papers of selected publications was developed. Thirty-seven relevant papers were identified (25 English, 11 Chinese and one Japanese-language study) including 28 randomized controlled trials. While there was significant heterogeneity in study length, treatment intensity and clinical measures, following a critical review of the published data combined with expert opinion, the following clinical practice recommendations were agreed in order to assist healthcare providers: in adults, long-term treatment with calcipotriol/betamethasone dipropionate is well tolerated and efficacious for up to 1 year on an 'as needed' basis, and for up to 16 weeks on a fixed-treatment regimen. Calcipotriol is also well tolerated and efficacious when used long term (up to 52 weeks) 'as needed' and for up to 20 weeks on a fixed-treatment regimen. Used on an 'as needed' basis for up to 1 year, the safety and efficacy profile of fixed-dose combination calcipotriol/betamethasone dipropionate is more favorable than calcipotriol alone; regular consultation between patients and their dermatologist/primary care physician is required to review psoriasis symptoms and adjust treatment accordingly; a specific treatment goal should be agreed on initiation of topical agent(s) to determine when long-term treatment can begin or if a regimen change is warranted; and application frequency during the continued treatment phase should consider the patients' treatment expectations and goals.

Scalp Psoriasis: A Literature Review of Effective Therapies and Updated Recommendations for Practical Management

The scalp is one of the most commonly affected regions in psoriasis. However, scalp psoriasis can be difficult to treat because of challenges in the delivery of therapy. Effective therapeutic regimens for scalp psoriasis are essential to improving the quality of life of patients. Recent data on topical therapies, phototherapy, systemic agents, and complementary therapy have demonstrated that it is possible to achieve and maintain significant improvement in scalp psoriasis. In this review, efficacy data for these modalities and an algorithm for the practical management of scalp psoriasis are presented.

Monocytic Cytokines in Autoimmune Polyglandular Syndrome Type 2 Are Modulated by Vitamin D and HLA-DQ

Context

Autoimmune polyglandular syndrome (APS-2: autoimmune Addison’s disease or type 1 diabetes) is conferred by predisposing HLA molecules, vitamin D deficiency, and heritable susceptibility. Organ destruction is accompanied by cytokine alterations. We addressed the monocytic cytokines of two distinct APS-2 cohorts, effects of vitamin D and HLA DQ risk.

Methods

APS-2 patients (n = 30) and healthy controls (n = 30) were genotyped for HLA DQA1/DQB1 and their CD14+ monocytes stimulated with IL1β and/or 1,25(OH)₂D₃ for 24 h. Immune regulatory molecules (IL-6, IL-10, IL-23A, IL-15, CCL-2, PD-L1), vitamin D pathway gene transcripts (CYP24A1, CYP27B1, VDR), and CD14 were analyzed by enzyme-linked immunosorbent assay and RTqPCR.

Results

Pro-inflammatory CCL-2 was higher in APS-2 patients than in controls (p = 0.001), whereas IL-6 showed a trend – (p = 0.1). In vitro treatment with 1,25(OH)₂D₃ reduced proinflammatory cytokines (IL-6, CCL-2, IL-23A, IL-15) whereas anti-inflammatory cytokines (IL-10 and PD-L1) rose both in APS-type 1 diabetes and APS-Addison´s disease. Patients with adrenal autoimmunity showed a stronger response to vitamin D. Expression of IL-23A and vitamin D pathway genes VDR and CYP27B1 varied by HLA genotype and was lower in healthy individuals with high-risk HLA (p = 0.0025; p = 0.04), while healthy controls with low-risk HLA showed a stronger IL-10 and CD14 expression (p = 0.01; p = 0.03).

Conclusion

1,25(OH)₂D₃ regulates the monocytic response in APS-2 disorders type 1 diabetes or Addison´s disease. The monocytic cytokine profile of individuals carrying HLA high-risk alleles is proinflammatory, enhances polyglandular autoimmunity and can be targeted by vitamin D.

PSO-LONG: Design of a Novel, 12-Month Clinical Trial of Topical, Proactive Maintenance with Twice-Weekly Cal/BD Foam in Psoriasis

Background

Psoriasis vulgaris is commonly treated with topical corticosteroids and vitamin D analogues. Although potent and super-potent topical corticosteroids are very effective at clearing psoriasis, with short-term reactive treatment durations, symptoms usually recur after treatment discontinuation, necessitating long-term disease management strategies. A foam formulation of calcipotriol and betamethasone dipropionate (Cal/BD foam), consisting of calcipotriol 50 μg/g and betamethasone dipropionate 0.5 mg/g, is approved for the daily treatment of psoriasis for up to 4 weeks. Here, we describe a clinical trial protocol for evaluating the long-term safety and efficacy of twice-weekly Cal/BD foam as a proactive topical maintenance therapy for plaque psoriasis for up to 52 weeks.

Objective

The aim of this trial was to evaluate the safety and efficacy of Cal/BD foam when applied twice weekly for up to 52 weeks as proactive maintenance therapy, with the goal of preventing or delaying disease relapse as long as possible while minimizing adverse effects.

Methods

Once-daily Cal/BD foam treatment responders from an initial 4-week open-label period were randomized to receive Cal/BD foam or foam vehicle applied to previously cleared plaques twice weekly for up to 52 weeks. In case of relapse, affected subjects in either group received rescue therapy with once-daily Cal/BD foam for 4 weeks on active areas. Thus, the trial (NCT02899962) compared the long-term use of Cal/BD foam in a proactive approach with a conventional, reactive approach.

Planned Outcomes

Efficacy endpoints included the time to first relapse, the number of relapse-free days, and the number of relapses during the maintenance phase. Safety assessments included adverse events, incidence of rebound, local safety and tolerability scores, and effects on calcium metabolism and hypothalamic–pituitary–adrenal axis function.

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.

Calcipotriol/betamethasone dipropionate aerosol foam in the treatment of psoriasis: new perspectives for the use of an innovative topical treatment from real-life experience

The fixed-dose combination of calcipotriol/betamethasone dipropionate (Cal/BD foam) in aerosol foam formulation is approved for the treatment of plaque psoriasis, and showed prompt onset of action, persistent efficacy and safety both in clinical trials and in real-life studies. The use of Cal/BD foam and its future perspectives of use were discussed during the symposium "Go beyond with topical treatment in psoriasis", held at the 2019 World Congress of Dermatology. We herein present the key topics of the symposium, namely the importance of Cal/BD foam in overcoming poor adherence, the possibility of a proactive (long-term) management of psoriasis and its potential role beyond mild psoriasis. Furthermore, proper adherence to treatment is crucial to achieve optimal clinical outcomes. In clinical trials and real-life experiences, Cal/BD foam has proven to have a fast onset of action and a good benefit/risk ratio due to increased efficacy and similar safety profile compared with other Cal/BD formulations. Given its chronic nature, psoriasis requires a long-term management, also due to the presence of underlying 'silent' inflammation that persists beyond resolution of flares. Cal/BD foam appears a favorable treatment for long-term management, and a specific trial is ongoing to investigate this new proactive approach. Lastly, evidence both from clinical studies and real-life experiences supports the use of Cal/BD foam in patients with moderate-to-severe disease, and this approach also showed greater effectiveness over some non-biologic systemic treatments. Therefore, Cal/BD foam may be considered as the new gold standard in topical therapy for patients with plaque psoriasis.

Efficacy of Fixed-combination Calcipotriene 0.005% and Betamethasone Dipropionate 0.064% Foam for Scalp Plaque Psoriasis: Additional Analysis of a Phase II, Randomized Clinical Study

BACKGROUND: There are a variety of treatment options currently available for plaque psoriasis affecting the scalp, yet scalp psoriasis remains one of the most frustrating and difficult-to-manage forms of the disease. OBJECTIVE: We investigated the efficacy of fixed-combination calcipotriene 0.005% plus betamethasone dipropionate 0.064% (Cal/BD) foam for the treatment of scalp psoriasis. METHODS: Additional (including post-hoc) analysis was conducted on data from a Phase II, randomized, double-blind, multicenter study of Cal/BD foam for the treatment of psoriasis vulgaris (NCT01536938). A total of 302 patients, ages 18 years or older, with psoriasis vulgaris of at least mild severity (scalp involvement of at least 10%) were included; 100, 101, and 101 patients were randomized to once-daily Cal/BD foam, Cal foam, or BD foam, respectively. Assessments included a severity score for lesion redness, scaliness, and plaque thickness, modified Psoriasis Area and Severity Index (mPASI) score, proportion of patients with reduction of 50 percent or greater in total sign score (TSS-50), and proportion of patients with at least a 75-percent reduction in mPASI score (mPASI-75). RESULTS: Patients achieved greater improvements in their scalp psoriasis with Cal/BD foam versus BD or Cal foam alone at Week 4 considering mPASI, mPASI-75, and TSS-50 outcomes. After four weeks of treatment, more patients receiving Cal/BD foam had a severity score for redness, scaliness, and thickness indicating "none" or "mild" versus BD foam or Cal foam alone. Improvements on the scalp appear to be consistent with those on the trunk and limbs. CONCLUSION: Scalp lesion severity improved considerably and rapidly with a four-week regimen of Cal/BD foam, suggesting that Cal/BD foam is an effective topical treatment option for scalp psoriasis.

Calcipotriol and betamethasone dipropionate synergistically enhances the balance between regulatory and proinflammatory T cells in a murine psoriasis model

A topical medication combining calcipotriol (Cal) and betamethasone dipropionate (BDP) has proven effective in a number of randomized controlled trials performed in patients with psoriasis, but its mechanism of action has not been fully elucidated. We investigated whether the combination of Cal and BDP (Cal/BDP) in this topical medication had a synergistic effect on psoriasis-like dermatitis and explored the underlying immunological mechanisms in a murine psoriasis model induced by application of imiquimod. Cal/BDP synergistically inhibited ear thickening induced by imiquimod compared to monotherapy with either Cal or BDP. In addition, Cal/BDP significantly suppressed the interleukin (IL)-23/IL-17-producing T (T17) pathogenic axis, including expression of IL-17a, IL-23a, IL-22 and TNF-α mRNA in skin lesions and expansion of CCR6⁺ γδ T17 cells in the draining lymph nodes. Notably, Cal/BDP synergistically induced regulatory CD8⁺ T cells and also improved the balance between regulatory CD8⁺ or CD4⁺ T cells and proinflammatory CCR6⁺ γδ T17 cells in the draining lymph nodes. These results suggest synergistic anti-psoriatic activity of Cal/BDP with normalization of the imbalance between regulatory CD8⁺ or CD4⁺ T cells and proinflammatory CCR6⁺ γδ T17 cells, which contributes to successful control of psoriasis by Cal-BDP combination therapy.

Results of the long-term observational noninterventional prospective study BODYGUARD in psoriasis patients

Introduction. Currently there is insufficient data regarding routine use of various topical treatments for plaque psoriasis outside from randomized clinical trials, their efficacy, cost-effectiveness and perception by dermatologists and patients. The primary rationale for this study was local data generation for the long-term (up to 52 weeks) treatment of body psoriasis in Russian patients’ population with fixed-dose combination of calcipotriol and betamethasone dipropionate in the formulation of gel to evaluate patient’s adherence to the therapy and their satisfaction level.

Materials and methods. Primary study objectives were evaluation of the long-term (up to 52 weeks) treatment success of body psoriasis with fixed-dose combination of calcipotriol and betamethasone dipropionate gel by Physician (Physician Psoriasis Global Assessment (PsGA, 5-point scale)) and by patient (Patient’s Global Psoriasis Assessment (PaGA, 5-point scale) and overall patient’s satisfaction using 4-point scale), patient’s satisfaction with the treatment via Patient Preference Questionnaire (PPQ), patients’ adherence to the treatment using Questionnaire of Adherence, impact of treatment on patients’ quality of life using DLQI questionnaire, and patients’ readiness to buy topical therapy product out of pocket based on consumption of the study medication during follow up period. Patients received treatment with topical calcipotriol/betamethasone gel which was prescribed as a routine medication without connection to the study purposes for up to 8 weeks. After the treatment patients were followed up for up to 52 weeks; during this period they were allowed to continue treatment with either maintenance or intermittent schedule. 128 dermatologists participated in the study, 612 patients with body plaque psoriasis (mean age 42.0 ± 13.30 years) were included; from this sample 544 (88.7 %) patients underwent follow up.

Results. All 612 included patients received initial therapy with calcipotriol/betamethasone gel; during follow-up period 410 (76.1 %) patients received treatment by any schedule (out of 539 assessed). Overall treatment success based on average PsGA score: initially 3.0 ± 0.54, after appr.8 weeks — 1.3 ± 0.80 and after appr.52 week 1.1 ± 0.96; based on average PaGA score — initially 3.0 ± 0.54, after appr.8 weeks — 1.5 ± 0.88 and after appr.52 week 1.1 ± 0.99. The proportion of patients which described their overall satisfaction with the treatment as “satisfied” or “absolutely satisfied” equaled 92.3 % at visit at the end of active treatment and 93.1 % at visit up to 52 weeks afterwards. Also at visit at the end of active treatment 93.8 % of patients considered their current treatment as “more effective” than previous topical treatment they received. Patients’ adherence to the therapy was satisfactory — average application rate of calcipotriol/betamethasone (should be applied daily) gel at the last 7 days of treatment at visit at the end of active treatment comprised 5.6 ± 2.6 days, which means that 6 out of 7 days of the treatment were not missed. Initial DLQI score was 13.6 ± 5.95 and it reduced down to 3.89 ± 5.95 at visit at the end of active treatment (p < 0.001) reflecting positive impact of successful therapy on patients’ psychosocial wellbeing.

Discussion. Results of this study provides additional information regarding routine topical therapy in patients with plaque psoriasis. These findings demonstrate that the therapy of body plaque psoriasis with calcipotriol/betamethasone gel is effective both in short and long term according to the evaluation by dermatologists and by patients themselves. This therapy provides good rate of adherence and patients’ satisfaction as well as affects positively at patients’ psychosocial wellbeing assessed by DLQI score. 

A cost-effectiveness analysis of calcipotriol plus betamethasone dipropionate aerosol foam versus gel for the topical treatment of plaque psoriasis

BACKGROUND

Calcipotriol 50 µg/g and betamethasone 0.5 mg/g dipropionate (Cal/BD) aerosol foam formulation provides greater effectiveness and improved patient preference compared with traditional Cal/BD formulations for the topical treatment of plaque psoriasis.

OBJECTIVE

To determine the cost-effectiveness of Cal/BD foam compared with Cal/BD gel from the Australian perspective.

METHODS

A Markov model was developed to evaluate the cost-effectiveness of topical Cal/BD foam and gel for the treatment of people with plaque psoriasis. Treatment effectiveness, safety, and utilities were based on a randomized control trial, resource use was informed by expert opinion, and unit costs were obtained from public sources. Outcomes were reported in terms of 1-year costs, quality-adjusted life years, and incremental cost-effectiveness ratios. All costs were reported in 2017 Australian Dollars.

RESULTS

The model showed that patients using Cal/BD foam had more QALYs and higher costs over 1 year compared with patients using Cal/BD gel, resulting in a cost of $13,609 per QALY gained at 4-weeks. When 4 weeks of Cal/BD foam was compared with 8 weeks of Cal/BD gel treatment, Cal/BD foam was $8 less expensive and resulted in 0.006 more QALYs gained. Sensitivity analyses showed that, compared with Cal/BD ointment, Cal/BD foam was associated with an incremental cost of $15,091 per QALY gained.

CONCLUSION

Cal/BD foam is the most cost-effective Cal/BD formulation for the topical treatment of patients with plaque psoriasis.

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.

Vitamin D effects on monocytes' CCL-2, IL6 and CD14 transcription in Addison's disease and HLA susceptibility

Addison's disease is a rare autoimmune disorder leading to adrenal insufficiency and life-long glucocorticoid dependency. Vitamin D receptor (VDR) polymorphisms and vitamin D deficiency predispose to Addison's disease. Aim of the current study was, to investigate potential anti-inflammatory vitamin D effects on monocytes in Addison's disease, focusing on inflammatory CCL-2 and IL6, as well on monocyte CD14 markers. Addison's disease is genetically linked to distinct HLA susceptibility alleles. Therefore we analyzed, whether HLA genotypes differed for vitamin D effects on monocyte markers. CD14⁺ monocytes were isolated from Addison's disease patients (AD, n=13) and healthy controls (HC, n=15) and stimulated with 1,25-dihydroxyvitamin D₃ and IL1β as an inflammatory stimulant. Cells were processed for mRNA expression of CCL-2, IL6 and CD14 and DNA samples were genotyped for major histocompatibility class (MHC) class II-encoded HLA- DQA1-DQB1 haplotypes. We found a downregulation of CCL-2 after vitamin D treatment in IL1β-stimulated monocytes both from AD patients and HC (AD p<0.001; HC p<0.0001). CD14 expression however, was upregulated in both HC and AD patients after vitamin D treatment (p<0.001, respectively). HC showed higher CD14 transcription level than AD patients after vitamin D treatment (p=0.04). Compared to IL1β-induced inflammation, HC have increased CD14 levels after vitamin D treatment (p<0.001), whereas the IL1β-induced CD14 expression of AD patients' monocytes did not change after vitamin D treatment (p=0.8). AD patients carrying HLA high-risk haplotypes showed an increased CCL-2 expression after IL1β-induced inflammation compared to intermediate-risk HLA carriers (p=0.05). Also HC monocytes' CD14 transcription after IL1β and vitamin D co-stimulation differed according to HLA risk profile. We show that vitamin D can exert anti-inflammatory effects on AD patients' monocytes which may be modulated by HLA risk genotypes.

Calcipotriol Plus Betamethasone Dipropionate Aerosol Foam in Patients with Moderate-to-Severe Psoriasis: Sub-Group Analysis of the PSO-ABLE Study

BACKGROUND

Fixed-combination calcipotriol 50 μg/g plus betamethasone 0.5 mg/g (Cal/BD) aerosol foam is a new topical treatment for psoriasis. Although moderate-to-severe psoriasis is typically treated with systemic/biologic therapies, a topical treatment that is efficacious in these patients may be a significant cost-saving alternative to systemic therapy.

OBJECTIVE

The objective of this study was to assess the response to Cal/BD foam and gel in patients with moderate-to-severe psoriasis enrolled in the phase III, 12-week PSO-ABLE study.

METHODS

Patients eligible for this analysis had moderate-to-severe psoriasis, defined by the 'Rule of Tens': body surface area ≥10% or Psoriasis Area and Severity Index (PASI) [excluding head; modified PASI (mPASI)] >10 or Dermatology Life-Quality Index >10. Endpoints included: proportion of patients achieving mPASI75 or mPASI90; change in body surface area; proportion of patients clear/almost clear with a ≥2 grade improvement (i.e., treatment success); change in Dermatology Life-Quality Index.

RESULTS

Seventy-seven Cal/BD foam patients and 82 gel patients had moderate-to-severe psoriasis. A greater proportion achieved mPASI75 and mPASI90 with Cal/BD foam than gel at weeks 4, 8, and 12 (57.1 vs. 35.4%; p = 0.006 and 15.6 vs. 12.2% at week 12, respectively); overall reduction in mPASI from baseline to week 12 was 64% with the foam vs. 51% with the gel. Overall reduction in body surface area at week 12 was 50% with the foam and 39% with the gel. Treatment success rates were higher with the Cal/BD foam than the gel at weeks 1, 2, 4, 8 (p = 0.0089), and 12, and a greater proportion of foam patients achieved a Dermatology Life-Quality Index score of 0/1 at weeks 4 (p = 0.004), 8, and 12 (p = 0.001).

CONCLUSION

Cal/BD foam can be considered as a treatment option in some patients with moderate-to-severe psoriasis who are potential candidates for systemic therapy. CLINICALTRIALS.

Managing Scalp Psoriasis: An Evidence-Based Review

BACKGROUND

Scalp psoriasis is commonly the initial presentation of psoriasis, and almost 80 % of patients with psoriasis will eventually experience it.

OBJECTIVE

Although several systematic reviews and guidelines exist, an up-to-date evidence-based review including more recent progress on the use of biologics and new oral small molecules was timely.

METHODS

Of the 475 studies initially retrieved from PubMed and the 845 from Embase (up to May 2016), this review includes 27 clinical trials, four papers reporting pooled analyses of other clinical trials, ten open-label trials, one case series, and two case reports after excluding non-English literature.

RESULTS

To our knowledge, few randomized controlled trials (RCTs) are conducted specifically in scalp psoriasis. Topical corticosteroids provide good effects and are usually recommended as first-line treatment. Calcipotriol-betamethasone dipropionate is well tolerated and more effective than either of its individual components. Localized phototherapy is better than generalized phototherapy on hair-bearing areas. Methotrexate, cyclosporine, fumaric acid esters, and acitretin are well-recognized agents in the treatment of psoriasis, but we found no published RCTs evaluating these agents specifically in scalp psoriasis. Biologics and new small-molecule agents show excellent effects on scalp psoriasis, but the high cost of these treatments mean they may be limited to use in extensive scalp psoriasis.

CONCLUSIONS

More controlled studies are needed for an evidence-based approach to scalp psoriasis.

Calcipotriol Plus Betamethasone Dipropionate Aerosol Foam is Effective, Independent of Body Mass Index and the Extent and Severity of Psoriasis

Introduction

Good treatment adherence is important in the effective management of psoriasis and is related to both the frequency of applications and the amount of product used versus the recommended dose. The efficacy and safety of fixed combination calcipotriol 50 µg/g (Cal) and betamethasone 0.5 mg/g as dipropionate (BD) in the treatment of psoriasis is well established; an aerosol foam formulation has been developed to enhance adherence. This subanalysis from the Phase III PSO-FAST study evaluates the amount of Cal/BD foam used during treatment and the association between the extent and severity of baseline disease.

Methods

Patients (≥18 years) with mild-to-severe body psoriasis were randomized 3:1 to once-daily Cal/BD foam or vehicle. The amount of Cal/BD foam and vehicle used over the 4-week study period was evaluated according to three baseline disease assessments: extent of body surface area (BSA) affected by psoriasis, physician’s global assessment of disease severity (PGA) and modified psoriasis area and severity index (mPASI). Treatment success and mPASI75 rates were assessed according to body mass index (BMI) and body weight.

Results

323 patients were randomized to Cal/BD foam and 103 to vehicle. At week 4, the mean total amount of Cal/BD foam used was 120.8 g (n = 293), which was similar to the amount of vehicle used (128.9 g; n = 98). The total amount of Cal/BD foam used at week 4 was greater with increasing BSA and increasing severity of baseline PGA and mPASI. Throughout the study, 93.1% of patients in the Cal/BD foam group and 99.0% of patients in the vehicle group missed ≤10% of treatment applications. Treatment success and mPASI75 rates were generally similar when stratified according to BMI and body weight.

Conclusions

This subanalysis demonstrates that Cal/BD aerosol foam is used appropriately and is effective for the treatment of psoriasis, independent of BMI and the extent or severity of disease.

Calcipotriol plus betamethasone dipropionate aerosol foam provides superior efficacy vs. gel in patients with psoriasis vulgaris: randomized, controlled PSO-ABLE study

Background

Fixed combination calcipotriol 50 μg/g (Cal) plus betamethasone 0.5 mg/g (BD) foam has been developed as a new treatment option for patients with psoriasis.

Methods

The randomized, parallel‐group, investigator‐blinded Phase III, 12‐week PSO‐ABLE study compared the efficacy and safety of Cal/BD foam with Cal/BD gel. Patients aged ≥18 years with mild‐to‐severe psoriasis were randomized 4:4:1:1 to once‐daily Cal/BD foam, Cal/BD gel, foam vehicle or gel vehicle (NCT02132936). The primary efficacy endpoint was the proportion of patients who were clear/almost clear with a ≥ 2 grade improvement according to the physician's global assessment of disease severity (i.e. treatment success) at week 4 for Cal/BD foam vs. week 8 for Cal/BD gel. Secondary efficacy endpoints included: proportion of patients achieving at least a 75% reduction in modified psoriasis area and severity index (mPASI75), and time to treatment success (TTTS). Safety was monitored throughout.

Results

A total of 463 patients were randomized: Cal/BD foam (n = 185), Cal/BD gel (n = 188), foam vehicle (n = 47), gel vehicle (n = 43); overall completion rate was 90%. Cal/BD foam achieved higher treatment success rates (38% vs. 22%; P < 0.001) and mPASI75 (52% vs. 35%; P < 0.001) by week 4 than Cal/BD gel by week 8. Median TTTS with Cal/BD foam was 6 weeks; this could not be determined for Cal/BD gel as 50% treatment success was not achieved (P < 0.001). Adverse drug reactions were reported in 14 (7.6%) Cal/BD aerosol foam patients and 7 (3.7%) Cal/BD gel patients; all were single events except for itch with Cal/BD aerosol foam (n = 5; 2.7%) and worsening psoriasis with Cal/BD gel (n = 3; 1.6%).

Conclusion

Cal/BD aerosol foam showed significantly greater efficacy after 4 weeks, than 8 weeks of treatment with Cal/BD gel, with similar tolerability.

Management of scalp psoriasis: current perspectives

Psoriasis is a chronic inflammatory condition. The age of onset, chronicity, physical, and psychosocial consequences of the disease cause psoriasis to have a significant impact on patient quality of life. Scalp psoriasis is no different, and effective treatment results in an improvement in quality of life. Successful management of scalp psoriasis includes topical therapies that are acceptable to the patient for mild-to-moderate disease, and systemic therapies for recalcitrant or moderate-to-severe disease. The most effective topical therapies are corticosteroid products, or combination products with calcipotriol and corticosteroid. Newer vehicle options provide more attractive and pleasing products for patients and may improve adherence. The current perspectives for management of scalp psoriasis are discussed including available data for systemic therapy of severe disease.

Topical treatments for scalp psoriasis

BACKGROUND

People with chronic plaque psoriasis often have lesions on the scalp. Hair makes the scalp difficult to treat and the adjacent facial skin is particularly sensitive to topical treatments.

OBJECTIVES

To assess the efficacy and safety of topical treatments for scalp psoriasis.

SEARCH METHODS

We searched the following databases up to August 2015: the Cochrane Skin Group Specialised Register, CENTRAL (2015, Issue 7), MEDLINE (from 1946), EMBASE (from 1974) and LILACS (from 1982). We also searched five trials registers, screened abstracts of six psoriasis-specific conferences and checked the reference lists of included studies for further references to relevant randomised controlled trials.

SELECTION CRITERIA

Randomised controlled trials (RCTs) with a parallel-group, cross-over or within-patient design of topical treatments for people of all ages with scalp psoriasis.

DATA COLLECTION AND ANALYSIS

Two authors independently carried out study selection, data extraction and 'Risk of bias' assessment. Disagreements were settled by reference to a third author.To assess the quality of evidence, we focused on the following outcomes: 'clearance' or 'response' as assessed by the investigator global assessment (IGA), improvement in quality of life, adverse events requiring withdrawal of treatment and 'response' as assessed by the patient global assessment (PGA).We expressed the results of the single studies as risk ratios (RR) with 95% confidence intervals (CI) for dichotomous outcomes, and mean differences (MD) with 95% CI for continuous outcomes. If studies were sufficiently homogeneous, we meta-analysed the data by using the random-effects model. Where it was not possible to calculate a point estimate for a single study, we described the data qualitatively. We also presented the number needed to treat to benefit (NNTB).We categorised topical corticosteroids according to the German classification of corticosteroid potency as mild, moderate, high and very high.

MAIN RESULTS

We included 59 RCTs with a total of 11,561 participants. Thirty studies were either conducted or sponsored by the manufacturer of the study medication. The risk of bias varied considerably among the included studies. For instance, most authors did not state the randomisation method and few addressed allocation concealment. Most findings were limited to short-term treatments, since most studies were conducted for less than six months. Only one trial investigated long-term therapy (12 months). Although we found a wide variety of different interventions, we limited the grading of the quality of evidence to three major comparisons: steroid versus vitamin D, two-compound combination of steroid and vitamin D versus steroid monotherapy and versus vitamin D.In terms of clearance, as assessed by the IGA, steroids were better than vitamin D (RR 1.82; 95% CI 1.52 to 2.18; four studies, 2180 participants, NNTB = 8; 95% CI 7 to 11; moderate quality evidence). Statistically, the two-compound combination was superior to steroid monotherapy, however the additional benefit was small (RR 1.22; 95% CI 1.08 to 1.36; four studies, 2474 participants, NNTB = 17; 95% CI 11 to 41; moderate quality evidence). The two-compound combination was more effective than vitamin D alone (RR 2.28; 95% CI 1.87 to 2.78; four studies, 2008 participants, NNTB = 6; 95% CI 5 to 7; high quality evidence).In terms of treatment response, as assessed by the IGA, corticosteroids were more effective than vitamin D (RR 2.09; 95% CI 1.80 to 2.41; three studies, 1827 participants; NNTB = 4; 95% CI 4 to 5; high quality evidence). The two-compound combination was better than steroid monotherapy, but the additional benefit was small (RR 1.15; 95% CI 1.06 to 1.25; three studies, 2444 participants, NNTB = 13; 95% CI 9 to 24; moderate quality evidence). It was also more effective than vitamin D alone (RR 2.31; 95% CI 1.75 to 3.04; four studies, 2222 participants, NNTB = 3; 95% CI 3 to 4; moderate quality evidence).Reporting of quality of life data was poor and data were insufficient to be included for meta-analysis.Steroids caused fewer withdrawals due to adverse events than vitamin D (RR 0.22; 95% CI 0.11 to 0.42; four studies, 2291 participants; moderate quality evidence). The two-compound combination and steroid monotherapy did not differ in the number of adverse events leading withdrawal (RR 0.88; 95% CI 0.42 to 1.88; three studies, 2433 participants; moderate quality evidence). The two-compound combination led to fewer withdrawals due to adverse events than vitamin D (RR 0.19; 95% CI 0.11 to 0.36; three studies, 1970 participants; high quality evidence). No study reported the type of adverse event requiring withdrawal.In terms of treatment response, as assessed by the PGA, steroids were more effective than vitamin D (RR 1.48; 95% CI 1.28 to 1.72; three studies, 1827 participants; NNTB = 5; 95% CI 5 to 7; moderate quality evidence). Statistically, the two-compound combination was better than steroid monotherapy, however the benefit was not clinically important (RR 1.13; 95% CI 1.06 to 1.20; two studies, 2226 participants; NNTB = 13; 95% CI 9 to 26; high quality evidence). The two-compound combination was more effective than vitamin D (RR 1.76; 95% CI 1.46 to 2.12; four studies, 2222 participants; NNTB = 4; 95% CI 3 to 6; moderate quality evidence).Common adverse events with these three interventions were local irritation, skin pain and folliculitis. Systemic adverse events were rare and probably not drug-related.In addition to the results of the major three comparisons we found that the two-compound combination, steroids and vitamin D monotherapy were more effective than the vehicle. Steroids of moderate, high and very high potency tended to be similarly effective and well tolerated. There are inherent limitations in this review concerning the evaluation of salicylic acid, tar, dithranol or other topical treatments.

AUTHORS' CONCLUSIONS

The two-compound combination as well as corticosteroid monotherapy were more effective and safer than vitamin D monotherapy. Given the similar safety profile and only slim benefit of the two-compound combination over the steroid alone, monotherapy with generic topical steroids may be fully acceptable for short-term therapy.Future RCTs should investigate how specific therapies improve the participants' quality of life. Long-term assessments are needed (i.e. 6 to 12 months).

Superior efficacy of calcipotriene and betamethasone dipropionate aerosol foam versus ointment in patients with psoriasis vulgaris--A randomized phase II study

Background: An aerosol foam formulation of fixed combination calcipotriene 0.005% (as hydrate; Cal) plus betamethasone dipropionate 0.064% (BD) was developed to improve psoriasis treatment. Objectives: To compare the efficacy and safety of Cal/BD aerosol foam with Cal/BD ointment after 4 weeks. Methods: In this Phase II, multicenter, investigator-blind, 4-week trial, adult patients with psoriasis vulgaris were randomized to Cal/BD aerosol foam, Cal/BD ointment, aerosol foam vehicle or ointment vehicle (3:3:1:1). The primary efficacy endpoint was the proportion of patients at week 4 who achieved treatment success (clear or almost clear with at least a two-step improvement) according to the physician’s global assessment of disease severity. Results: In total, 376 patients were randomized. At week 4, significantly more patients using Cal/BD aerosol foam achieved treatment success (54.6% versus 43.0% [ointment]; p = 0.025); mean modified (excluding the head, which was not treated) psoriasis area and severity index score was significantly different between Cal/BD aerosol foam and Cal/BD ointment (mean difference –0.6; p = 0.005). Rapid, continuous itch relief occurred with both active treatments. One adverse drug reaction was reported with Cal/BD aerosol foam (application site itch). Conclusions: Cal/BD aerosol foam demonstrates significantly greater efficacy and similar tolerability compared with Cal/BD ointment for psoriasis treatment.

Real-life effectiveness of once-daily calcipotriol and betamethasone dipropionate gel vs. ointment formulations in psoriasis vulgaris: final analysis of the 52-week PRO-long study

Background

Topical therapies are the mainstay of treatment for psoriasis vulgaris. The fixed combination of calcipotriol (Cal) 50 μg/g plus betamethasone 0.5 mg/g (as dipropionate; BD) is a first‐line topical treatment and available as a gel or ointment. The use of these fixed combination products was compared in PRO‐long, a long‐term noninterventional study, for which interim results (4 and 12 weeks) have previously been reported.

Objective

To describe and compare patients’ perspectives on the fixed combination gel and ointment formulations; to include efficacy, adherence behaviour, treatment satisfaction and health‐related quality of life (HRQoL) aspects during long‐term real‐life psoriasis management.

Methods

PRO‐long was a multicentre, prospective, observational, 52‐week study of patients prescribed fixed combination Cal/BD gel or ointment in clinical practice. For final analysis the following were assessed at weeks 24, 36 and 52: differences in the proportion of patients with ‘mild’/‘very mild’ disease according to patient's global assessment of disease severity, adherence behaviour, treatment satisfaction (nine‐item treatment satisfaction questionnaire for medication) and HRQoL (Skindex‐29).

Results

Patients (n = 328) were prescribed once‐daily Cal/BD gel (n = 152) or ointment (n = 176). At week 52, a higher proportion of patients reported that the severity of their psoriasis was ‘mild’/‘very mild’ vs. baseline (gel: 60.2 vs. 47.1%; ointment: 58.8 vs. 42.4%), with greater treatment satisfaction reported in patients using gel vs. those using ointment. A higher proportion of patients found the gel ‘easy’ to use compared with the ointment (66.7 vs. 45.2%). Daily application of treatment took ≤5 min for 86.1% of patients using gel and 71.0% of patients using ointment.

Conclusion

This real‐life study has demonstrated similar effectiveness between the Cal/BD formulations. However, over a 52‐week treatment period, patients reported greater treatment satisfaction with the gel, which was considered easier to use, faster to apply and overall a more convenient product.

Calcipotriol/betamethasone for the treatment of psoriasis: efficacy, safety, and patient acceptability

Background

One of the advances in the treatment of plaque-type psoriasis is combined local therapy with calcipotriol and betamethasone. To provide both ingredients in a two-compound product, efforts have been made to unite calcipotriol and betamethasone because they are usually inactivated when present in the same formulation. This aspect was resolved when carefully designed vehicle components were invented (gel and ointment). This article reviews the efficacy, safety, and patient acceptability of calcipotriol/betamethasone dipropionate.

Methods

A literature search of all articles published until February 2015 was performed, including the largest medical databases. The search strategy for evaluating the main topics of this review – efficacy, safety, and patient acceptability – was defined before checking the publications.

Results

Seventy references were found and checked for relevance. For efficacy, the proportion of patients whose psoriasis improved was always significantly higher in the two-compound group compared to the group treated with the individual substances. In the context of safety, the fixed combination was generally associated with a lower risk of adverse events. In terms of patient acceptability, the fixed combination led to a significant improvement in quality of life. The two-compound product was more convenient to handle and time saving compared to former treatments.

Conclusion

Calcipotriol/betamethasone dipropionate in a fixed combination is an effective and well-tolerated medication in mild-to-moderate psoriasis of body and scalp and, in addition, is an evidence-based treatment modality.

Real-life effectiveness of topical vitamin d and corticosteroid combination therapy in psoriasis : moving beyond clinical trials

To provide successful care for psoriasis patients, treatments must be efficacious and safe as well as improve the patients' overall well-being. Efficacy and safety are generally established by randomized, controlled clinical trials. However, because of the rigid conditions under which randomized, controlled clinical trials are conducted, they do not reflect patient experience in real-life clinical practice; that is, they do not measure treatment effectiveness in the real world. Factors such as adherence to therapy, treatment satisfaction, and quality of life may be rated unrealistically high in randomized, controlled clinical trials. Observational studies using real-life patient populations, and capturing patient-reported outcomes, are useful at better assessing a treatment's effectiveness. Healthcare professionals and payers may gain valuable insights from patient-reported outcomes data that can be used in making treatment decisions. For localized plaque psoriasis, topical vitamin D analog and corticosteroid combination therapy is recommended as a first-line treatment. This commentary addresses the concept of clinical trial efficacy versus real-life effectiveness in psoriasis treatment using vitamin D and corticosteroid topical combination therapy as a model.

Topical long-term therapy of psoriasis with vitamin D₃ analogues, corticosteroids and their two compound formulations: position paper on evidence and use in daily practice

BACKGROUND

Current data from daily practice show that vitamin D₃ analogues, corticosteroids and their fixed combination products are used heterogeneously for topical long-term treatment of psoriasis.

AIM

To evaluate scientific evidence about topical long-term therapy with vitamin D3 analogues, corticosteroids and their two-compound-products in psoriasis vulgaris and scalp psoriasis and to develop daily practice recommendations.

METHODS

Systematic literature review via PubMed and Embase and informal expert consensus.

RESULTS

The search strategy identified 21 relevant clinical trials. Best evidence regarding topical long term treatment was available for the two-compound-formulation containing calcipotriene and betamethasone. In a comparative trial in psoriasis vulgaris the two-compound-formulation showed superior tolerability and cost effectiveness compared to monotherapy. In scalp psoriasis the two-compound-gel was superior compared to calcipotriene monotherapy. Standardized and simplified treatment application modes resulted in a better clinical outcome comparing to on-demand therapies.

DAILY PRACTICE RECOMMENDATIONS

Patients should be proactively involved in the choice of treatment, formulation and mode of application. Besides long-term treatment with the two-compound-formulation other treatment regimens including calcipotriene monotherapy can also be considered. Due to a favorable risk-benefit ratio in maintenance trials and due to better cost-effectiveness the application of two-compound-products once or twice a week after initial therapy is recommended.

Current topical therapy of psoriatic patients suffering from scalp lesions

Scalp lesions reduce the life quality of psoriatic patients. Goal. to assess the efficacy and safety of the topical therapy of psoriatic patients suffering from scalp lesions using a combination gel containing betamethasone and calcipotriol. Materials and methods. As many as 32 psoriatic patients suffering from scalp lesions received treatment. The clinical assessment was conducted using the PASI index. The Dermatology Life Quality Index (DLQI) was used to assess the patients’ life quality. Results. A reliable reduction in the PASI (by 69.9%) and DLQI (fivefold) indices was observed in most of the patients. No adverse effects or complications were observed as a result of the topical therapy of psoriatic patients with the gel containing betamethasone and calcipotriol. Conclusion. High efficacy and safety of the treatment method were observed.

Topical nicotinamide in combination with calcipotriol for the treatment of mild to moderate psoriasis: A double-blind, randomized, comparative study

Background:

Current treatment strategies of psoriasis are not completely satisfactorily. By inhibiting inflammatory cytokines, nicotinamide may enhance the effects of current topical treatments. We investigated whether the combination of topical calcipotriol and nicotinamide is more effective than calcipotriol alone in treatment of psoriasis.

Materials and Methods:

Adult patients with mild to moderate psoriasis were randomized to receive topical calcipotriol 0.005% and nicotinamide 4% in combination or calcipotriol 0.005% alone, twice daily for 12 weeks. Patients were visited by a dermatologist at baseline and then after the first and third month of therapy, and psoriasis severity was evaluated using the modified psoriasis area and severity index (PASI). Also, patient's satisfaction was evaluated at the end of the trial using a 10-point rating scale.

Results:

Sixty-five patients (35 males, mean age = 36.5 ± 8.5 years) completed the trial. Lesions on both sides were similar regarding baseline PASI score. At the end of the trial, PASI score was more reduced with calcipotriol+nicotinamide compared to calcipotriol alone (83.6 ± 7.9% vs. 77.8 ± 9.7%, P < 0.001). Patients were also more satisfied with the improvement of lesions with calcipotriol+nicotinamide compared with calcipotriol alone (P < 0.001). Side effects included mild erythema and pruritus (4.6%) and moderate burning and sensitivity to light (3.0%).

Conclusions:

Nicotinamide can enhance the efficacy of calcipotriol when used in combination for topical psoriasis treatment, and it may be a good adjuvant to the current treatment regimens of psoriasis.

Topical therapies for the treatment of localized plaque psoriasis in primary care: a cost-effectiveness analysis

BACKGROUND

Topical therapies are a mainstay of psoriasis treatment, but they vary substantially in terms of cost.

OBJECTIVES

To determine the cost-effectiveness and optimal treatment sequence for psoriasis of the trunk, limbs and scalp.

METHODS

Probabilities of response from a network meta-analysis were used to determine the short-term efficacy of topical therapies. Longer-term outcomes, including relapse, were informed by published evidence and clinical opinion. Benefits of treatment were measured as quality-adjusted life years (QALYs). Direct costs included topical agents, primary and secondary care visits and second-line therapies for treatment failures.

RESULTS

For the trunk and limbs, initial treatment with a two-compound formulation (TCF) product containing vitamin D and potent corticosteroid provided the most QALYs, followed by separate morning and evening application of vitamin D and potent corticosteroid [two-compound application, TCA (am/pm)], and then twice-daily potent corticosteroids. The use of twice-daily potent corticosteroids was the most cost-effective first-line strategy (incremental cost-effectiveness ratio £ 20,000 per QALY), followed by TCA (am/pm) (£ 22,658 per QALY) and TCF product (£ 179,439 per QALY). For scalp psoriasis, initial treatment with very potent corticosteroids generated the most QALYs, followed by TCF product and then potent corticosteroids. Very potent corticosteroids were the most cost-effective treatment but, if too aggressive, potent corticosteroids were optimal followed by TCF product (£ 219,846 per QALY). The cost-effectiveness of second- and third-line topical agents varied with the assumptions made.

CONCLUSIONS

Potent corticosteroids, used alone or in combination with vitamin D, are the most cost-effective treatment for patients with psoriasis of the trunk and limbs. Potent or very potent corticosteroids are the most cost-effective treatment for patients with scalp psoriasis.

Topical treatments for chronic plaque psoriasis

BACKGROUND

Chronic plaque psoriasis is the most common type of psoriasis, and it is characterised by redness, thickness, and scaling. First-line management of chronic plaque psoriasis is with topical treatments, including vitamin D analogues, topical corticosteroids, tar-based preparations, dithranol, salicylic acid, and topical retinoids.

OBJECTIVES

To compare the effectiveness, tolerability, and safety of topical treatments for chronic plaque psoriasis, relative to placebo, and to similarly compare vitamin D analogues (used alone or in combination) with other topical treatments.

SEARCH METHODS

We updated our searches of the following databases to February 2011: the Cochrane Skin Group Specialised Register, CENTRAL in The Cochrane Library (2011, Issue 2), MEDLINE (from 1948), EMBASE (from 1980), Science Citation Index (from 2008), Conference Proceedings Citation Index - Science (from 2008), BIOSIS (from 1993), Dissertation Abstracts via DialogClassic (all publication years), and Inside Conferences (all publication years).We identified ongoing and unpublished studies from the UK Clinical Research Network Study Portfolio and the metaRegister of Controlled Trials. We checked the bibliographies of published studies and reviews for further references to relevant trials, and we contacted trialists and companies for information about newly published studies.A separate search for adverse effects was undertaken in February 2011 using MEDLINE and EMBASE (from 2005).Final update searches for both RCTs and adverse effects were undertaken in August 2012. Although it has not been possible to incorporate RCTs and adverse effects studies identified through these final searches within this review, we will incorporate these into the next update.

SELECTION CRITERIA

Randomised trials comparing active topical treatments against placebo or against vitamin D analogues (used alone or in combination) in people with chronic plaque psoriasis.

DATA COLLECTION AND ANALYSIS

One author extracted study data and assessed study quality. A second author checked these data. We routinely contacted trialists and companies for missing data. We also extracted data on withdrawals and on local and systemic adverse events. We defined long-term trials as those with a duration of at least 24 weeks.

MAIN RESULTS

This update added 48 trials and provided evidence on 7 new active treatments. In total, the review included 177 randomised controlled trials, with 34,808 participants, including 26 trials of scalp psoriasis and 6 trials of inverse psoriasis, facial psoriasis, or both. The number of included studies counted by Review Manager (RevMan) is higher than these figures (190) because we entered each study reporting a placebo and an active comparison into the 'Characteristics of included studies' table as 2 studies.When used on the body, most vitamin D analogues were significantly more effective than placebo, with the standardised mean difference (SMD) ranging from -0.67 (95% CI -1.04 to -0.30; 1 study, 119 participants) for twice-daily becocalcidiol to SMD -1.66 (95% CI -2.66 to -0.67; 1 study, 11 participants) for once-daily paricalcitol. On a 6-point global improvement scale, these effects translate into 0.8 and 1.9 points, respectively. Most corticosteroids also performed better than placebo; potent corticosteroids (SMD -0.89; 95% CI -1.06 to -0.72; I² statistic = 65.1%; 14 studies, 2011 participants) had smaller benefits than very potent corticosteroids (SMD -1.56; 95% CI -1.87 to -1.26); I² statistic = 81.7%; 10 studies, 1264 participants). On a 6-point improvement scale, these benefits equate to 1.0 and 1.8 points, respectively. Dithranol, combined treatment with vitamin D/corticosteroid, and tazarotene all performed significantly better than placebo.Head-to-head comparisons of vitamin D for psoriasis of the body against potent or very potent corticosteroids had mixed findings. For both body and scalp psoriasis, combined treatment with vitamin D and corticosteroid performed significantly better than vitamin D alone or corticosteroid alone. Vitamin D generally performed better than coal tar, but findings relative to dithranol were mixed. When applied to psoriasis of the scalp, vitamin D was significantly less effective than both potent corticosteroids and very potent corticosteroids. Indirect evidence from placebo-controlled trials supported these findings.For both body and scalp psoriasis, potent corticosteroids were less likely than vitamin D to cause local adverse events, such as burning or irritation. Combined treatment with vitamin D/corticosteroid on either the body or the scalp was tolerated as well as potent corticosteroids, and significantly better than vitamin D alone. Only 25 trials assessed clinical cutaneous dermal atrophy; few cases were detected, but trials reported insufficient information to determine whether assessment methods were robust. Clinical measurements of dermal atrophy are insensitive and detect only the most severe cases. No comparison of topical agents found a significant difference in systemic adverse effects.

AUTHORS' CONCLUSIONS

Corticosteroids perform at least as well as vitamin D analogues, and they are associated with a lower incidence of local adverse events. However, for people with chronic plaque psoriasis receiving long-term treatment with corticosteroids, there remains a lack of evidence about the risk of skin dermal atrophy. Further research is required to inform long-term maintenance treatment and provide appropriate safety data.

Practicability of combined treatment with calcipotriol/betamethasone gel (Daivobet® Gel) and improvement of quality of life in patients with psoriasis

BACKGROUND

The successful treatment of psoriasis depends not only on the efficacy of the medication but also on patientsí acceptance and adherence to the prescribed regimen.

PATIENTS AND METHODS

In this non-interventional, prospective trial 579 patients with psoriasis were treated once daily with the fixed combination of calcipotriol 50 μg/g plus betamethasone 0.5 mg/g (Daivobet® Gel) for 4 weeks. Comparing the new medication to their previous treatment, patients assessed their quality of life by means of the Dermatology Life Quality Index (DLQI), reported their therapy- associated burden in daily life by the Psoriasis Disability Index (PDI) and assessed how easy the new medication was to employ. Disease severity was rated at the start and end of the study by physicians and patients using a Global Assessment (PGA from 0-5 points) and the Body Surface Area (BSA) assessed by the physicians.

RESULTS

Quality of life improved from 8.7 to 3.2 points (p < 0.0001) parallel to a significant decrease of PGA by 39.6% (p < 0.0001) and BSA (72.5% of patients with BSA > 4% before vs. 37.3% after therapy). The application of the study medication was 30% less time-consuming and handling associated with significantly higher patient satisfaction. Efficacy and tolerability of Daivobet® Gel versus prior treatment were judged "very good" in 85.7% vs. 27.6% of patients.

CONCLUSIONS

The study substantiates a significant improvement of the quality of life during therapy with the fixed combination. Patients benefit from the convenience and time-saving as compared to their prior treatment. Thus, Daivobet® Gel can be recommended as an effective and well-tolerated treatment which may easily be integrated into daily life of patients with psoriasis.

Recommendations for a patient-centered approach to the assessment and treatment of scalp psoriasis: a consensus statement from the Asia Scalp Psoriasis Study Group

BACKGROUND

International consensus statements on the management of scalp psoriasis are available, but no such recommendations exist for Asia.

METHODS

The Asia Scalp Psoriasis Study Group (ASPSG) met in May 2011 to review the epidemiologic pattern of scalp psoriasis in Southeast Asia and to develop Asia-specific recommendations for its management.

RESULTS

The overall prevalence of psoriasis in Asia is <0.3%, but 75-90% have scalp involvement, whether isolated or with lesions elsewhere, which can negatively impact quality of life (QoL). Treatment decisions should be based primarily on objective disease severity, but should also take account of patient QoL. Psychosocial support and more aggressive treatment should be offered to all patients with moderate to severe QoL impairment. Topical therapy is indicated first-line in all patients, with combination therapy (corticosteroid + calcipotriol), more occlusive formulations, keratolytics, and very potent corticosteroids for patients needing greater or faster efficacy. Systemic therapies, light or laser treatments should be reserved for patients with severe and recalcitrant disease.

CONCLUSIONS

The ASPSG recommends a patient-centered approach to scalp psoriasis management, consistent with the international consensus statements. Asian physicians should also consider patient QoL, prior treatment response, formulation preferences, likely adherence, cost, time available for self-management, and potential adverse events.
