Psoriasis Patients Have Higher Risk of Sexual and Erectile Dysfunction

MedicalResearch.com Interview with:

Severe Psoriasis; penn medicine

Severe Psoriasis

Alejandro Molina-Leyva, MD PhD
Dermatología, Hospital Universitario Virgen de las Nieves, Granada, Spain

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: Psoriasis is a frequent  chronic inflammatory skin disease characterized by the presence of erythematous papulosquamous lesions that can affect any part of the body. The modification of body image and the subjective symptoms associated like itch or even pain can produce an important impairment of quality of life.

Sexuality is a major aspect of life that can be impaired by chronic disease but it is usually an overlooked topic during medical consultations maybe because of lack of knowledge or embarrassment. There is a increasing scientific evidence supporting the relationship between psoriasis and sexual dysfunction.

The aim of our study is to synthesize this scientific evidence in order to help dermatologists to understand the burden of the problem, to identify patients at higher risk and the available therapeutic options.

MedicalResearch.com: What should readers take away from your report?

Response: Patients with psoriasis present a higher risk of sexual and erectile dysfunction compared to general population. Approximately 50% of patients with psoriasis experience some degree of sexual dysfunction. Anxiety or depression, genital psoriasis or psoriasis arthritis increase the risk of sexual dysfunction among patients with psoriasis, special attention should be given to these patients. The improvement of psoriasis associated with biologic drugs have demonstrated to improve sexual dysfunction.

Psoriasis patients should be inquired about sexual problems during routine consultation, especially those that present risk factors. The presence of sexual or erectile dysfunction could be considered as an additional severity factor  for treatment decision.

MedicalResearch.com: What recommendations do you have for future research as a result of this work?

Response: Future research should point towards to investigate the role of systemic inflammation and pro-inflammatory cytokines and psoriasis. We recommend researchers the use specific validated tool to assess sexual dysfunction. Upcoming clinical trials of new drugs for psoriasis should include specific analyses regarding sexual and erectile dysfunction.

MedicalResearch.com: What is the background for this study?

Response: Our psoriasis patients have long asked us about the role of diet on psoriasis. Previously, there was a lack of evidence synthesis on the relationship between psoriasis and diet. As such, providers were mostly unable to address their patients questions on the role of diet on psoriasis.

This pivotal effort from the National Psoriasis Foundation has been a few years in the making. We looked at the role of diet on psoriasis and psoriatic arthritis based on a careful synthesis of the scientific studies available to us currently.

Richard Wang, M.D., Ph.D. 
Assistant Professor Dermatology
UT Southwestern Medical Center 

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: Targeting cellular metabolism is currently being explored as a new way to diagnose and treat diseases. In particular, there has been increasing interest in specifically targeting metabolic pathways are preferentially altered in disease states, like cancer.  Although an increased dependence on glucose transport and metabolism has been well established for rapidly proliferating cells, attempts to target this conserved pathway have been limited by concerns about the high potential for side effects from the systemic inhibition of glucose transport.

To investigate the feasibility of targeting glucose transport in skin diseases, we investigated the effect of inhibiting glucose transport in the skin by deleting the primary glucose transporter in the skin, Glut1, in mouse keratinocytes. We confirmed that the Glut1-deficient keratinocytes showed metabolic and oxidative stress and impaired proliferation. However, the keratinocyte-specific ablation of Glut1 did not compromise mouse skin development and barrier function. Metabolomic profiling revealed sphingolipid, hexose, amino acid, and nucleotide adaptations in Glut1-deficient keratinocytes. However, Glut1 deficient skin did show defects in both proliferation and migration after physiologically relevant stressors like excisional wounds and UV-B irradiation.

Given its importance during stressors, we further tested whether Glut1 was important in the pathogenesis of psoriasis models. Notably, both the genetic and pharmacological inhibition of Glut1 decreased hyperplasia in mouse and human organic models of psoriasis. Moreover, the topical application of a Glut1 inhibitor further decreased inflammation in these models. The ability to deliver glucose transport inhibitors specifically to the skin may limit the adverse effects from the systemic inhibition of glucose transport and suggests that the topical inhibition of glucose transport may be a novel approach to treat hyperproliferative and inflammatory skin diseases.  Continue reading

MedicalResearch.com: What is the background for this study? What are the main findings? 

Response: Genital psoriasis can be an uncomfortable and burdensome condition that many people living with moderate-to-severe plaque psoriasis experience. Due to the significant impact, Lilly conducted a 12-week Phase 3b clinical trial with patients with moderate-to-severe genital psoriasis treated with ixekizumab, which found that patients had a greater decrease in the impact of their condition on sexual activity compared to placebo as early as one week.

Specifically, trial patients were randomized to receive ixekizumab (80 mg every two weeks, following a 160-mg starting dose) or placebo and researchers measured pre-specified patient-reported outcomes, including the Genital Psoriasis Sexual Impact Scale (GPSIS), which is composed of the Sexual Activity Avoidance (Avoidance) and Impact of Sexual Activity on Genital Psoriasis Symptoms (Impact) subscales. Patient-reported outcomes were also measured by the Sexual Frequency Questionnaire (SFQ) item 2, evaluating the impact of genital psoriasis on the frequency of sexual activity, and the Dermatology Life Quality Index (DLQI) item 9, evaluating the impact of skin symptoms on sexual difficulties.

At 12 weeks, patients reported the following outcomes:

  • DLQI Item 9 0/1: 92.0 percent of patients treated with ixekizumab compared to 56.8 percent of patients treated with placebo reported no (0) or little (1) sexual difficulties caused by skin symptoms.
  • SFQ Item 2 0/1:  78.4 percent of patients treated with ixekizumab compared to 21.4 percent of patients treated with placebo (reported the frequency of sexual activity was either never (0) or rarely (1) limited by genital psoriasis.
  • GPSIS-Avoidance 1/2:  76.7 percent of patients treated with ixekizumab compared to 25.7 percent of patients treated with placebo reported never (1) or rarely (2) avoiding sexual activity due to genital psoriasis.
  • GPSIS-Impact 1/2:  85.7 percent of patients treated with ixekizumab compared to 52.9 percent of patients treated with placebo reported worsening of genital psoriasis symptoms during or after sexual activity was very low/none at all (1) or low (2).

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: The majority cardiovascular events in psoriasis occur in patients at low risk by traditional cardiovascular risk calculators. It has been speculated that long-term exposure to systemic inflammation may increase the risk of adverse cardiovascular outcomes. Therefore, clinically available historical features such as disease duration may identify those at higher risk for cardiovascular disease.

Using a translational epidemiological approach, combining 18F-fluorodeoxyglucose positron emission tomography computed tomography scanning with nationwide epidemiological data of more than four million individuals, we provide the first convincing evidence to suggest a detrimental effect of psoriasis duration on cardiovascular disease beyond traditional cardiovascular risk factors, even in patients deemed “low-risk” by conventional risk scores. We found a 1% increase in future major adverse cardiovascular event risk per additional year of disease duration. This finding has an effect size similar to smoking, a well-established cardiovascular risk factor.

Secukinumab Provides Sustained Improvements in Dermatology-Specific Quality of Life in Moderate to Severe Psoriasis Patients Through 3 Years of Treatment

MedicalResearch.com
Eric Hughes
Global Development Franchise Head Immunology & Dermatology
Novartis

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: Psoriasis is a chronic immune-mediated inflammatory disease that negatively impacts patients’ quality of life (QOL); therefore QOL outcomes are increasingly recognized as an important measure of efficacy in psoriasis, complementing traditional measures of severity such as the Psoriasis Area and Severity Index (PASI).

Secukinumab, a fully human monoclonal antibody that selectively neutralizes interleukin-17A (IL-17A), exhibits significant efficacy in the treatment of moderate-to-severe psoriasis, ankylosing spondylitis and psoriatic arthritis, demonstrating a rapid onset of action and a favorable safety profile.

Biologic therapies for psoriasis have previously been associated with a fall-off in efficacy over time; accordingly, extended follow-up is required to adequately evaluate novel therapeutic strategies like IL-17A inhibition. Recently, results from the extension of the SCULPTURE secukinumab trial showed that high responses initially achieved with secukinumab at year 1 in the SCULPTURE study were sustained over time up to 3 years with no new or unexpected safety concerns. In this analysis, we examined whether the sustained efficacy observed in SCULPTURE up to 3 years was translated into sustained effect of secukinumab on patient’s QOL measured by the Dermatology Life Quality Index (DLQI) questionnaire.

SCULPTURE, a multi-center extension study, was conducted with subjects who completed 52 weeks of treatment. Subjects were randomized into two maintenance dosing regimens; a fixed-interval schedule of secukinumab 300 mg every 4 weeks (Fixed interval dosing regimen (FI) cohort), and secukinumab retreatment-as-needed (Retreatment as needed (RAN) cohort), in which subjects received placebo until start of relapse, at which time secukinumab 300 mg every 4 weeks was re-initiated.

The analysis using as-observed data showed that at Year 3, improvements in the total score on DLQI was well sustained in both FI and RAN cohorts. Approximately two-thirds of the subjects in the FI cohort reported no impact of skin disease on QOL (corresponding to a score of 0 or 1 on DLQI). The proportion of patients in the RAN cohort reporting no impact of the disease on their QOL was well sustained through 3 years but remained consistently lower than those observed in the FI cohort. The results for each subscale of the DLQI questionnaire were consistent with those with DLQI total score i.e. showing high and sustained proportions of patients reporting no impact of the disease on different domains of health-related QOL in the two secukinumab cohorts with greater effect in the FI cohort compared to the RAN cohort.

Secukinumab (Cosentyx) Provides Greater Improvement in Quality of Life, Work Productivity, and Daily Activity Than Ustekinumab (Stelara) in Moderate To Severe Psoriasis

MedicalResearch.com Interview with:
Eric Hughes, Global Head of Development, Immunology & Dermatology

Novartis Pharma AG
Basel, Switzerland

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: It is well established that psoriasis negatively affects quality of life and work productivity. However, how the treatments affect psoriasis severity (based on skin clearance, itch, pain and scaling symptoms), health-related quality of life (HRQOL), work productivity, and daily activity directly or indirectly (via other factors) are still largely unknown.

Secukinumab, a fully human monoclonal antibody that selectively neutralizes interleukin-17A (IL-17A), exhibits significant efficacy in the treatment of moderate-to-severe psoriasis, ankylosing spondylitis, and psoriatic arthritis, demonstrating a rapid onset of action and a favorable safety profile.

In CLEAR, a Phase 3b head-to-head study versus ustekinumab, secukinumab demonstrated sustained superior efficacy in clearing skin through Week 52, greater improvement in symptoms and HRQOL, greater relief of work and activity limitations, and a comparable safety profile. In this sub-analysis of the CLEAR study, Novartis was interested in examining the relationships among multiple variables that are thought to be important to patients with psoriasis. The direct and indirect (i.e. mediated) effects of treatment (secukinumab or ustekinumab) on psoriasis severity and patients’ HRQOL, work productivity, and daily activity were examined. The evaluation was conducted using structural equation modeling (or path analysis) and compared these relationships for secukinumab versus ustekinumab at 16 and 52 weeks. Structural equation modeling or path analysis is a statistical method that models the direct and indirect relationship between multiple patient-relevant outcomes simultaneously.

Goodness-of-fit statistics for all models were excellent confirming the robustness of the results. Results at Week 16 and at Week 52 for different Psoriasis Area and Severity Index (PASI) response categories (e.g. PASI 75, PASI 90, PASI 100) indicated that psoriasis treatment indirectly affected HRQOL and work productivity and daily activity, measured with the Dermatology Life Quality Index (DLQI) and the Work Productivity and Activity Impairment (WPAI) questionnaires, respectively.

Actually, greater effect of secukinumab over ustekinumab on DLQI was mediated by greater improvement of secukinumab in PASI response as well as by greater improvement in psoriasis-related symptoms (itch, pain and scaling). Greater effect of secukinumab over ustekinumab on work productivity and daily activity was mediated by greater improvement of secukinumab in psoriasis-related symptoms.

Dr. Jonathan L. Silverberg MD PhD MPH

Assistant Professor in Dermatology
Medical Social Sciences and Preventive Medicine
Northwestern University, Chicago, Illinois

Dr. Jonathan L. Silverberg MD PhD MPH Assistant Professor in Dermatology Medical Social Sciences and Preventive Medicine Northwestern University, Chicago, Illinois

Dr. Jonathan Silverberg

Response: Psoriasis is associated with a number of potential risk factors for developing osteoporosis and pathological fractures, including including low vitamin D, chronic inflammation, higher rates of cigarette smoking and systemic corticosteroid usage. We hypothesized that adults with psoriasis have higher rates of osteoporosis and pathological fractures.

We examined data from the 2002-2012 National Inpatient Sample, which contains a representative 20% sample of all hospitalizations in the United States. We found that psoriasis was associated with higher odds of osteopenia, osteoporosis, osteomalacia, ankylosing spondylitis, and pathological fractures. In particular, psoriasis was associated with vertebral, pelvic, femoral and tibial/fibular fractures. The associations between psoriasis and pathological fractures were more pronounced in women than men.

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: There significant delays in the diagnosis of psoriatic arthritis (PsA) among patients with psoriasis. Many patients with psoriasis experience musculoskeletal symptoms. The majority of them do not have PsA, but other non-inflammatory conditions such as fibromyalgia or osteoarthritis.

In this study, we aimed to assess whether the presence and the degree of musculoskeletal symptoms in psoriasis patients predict the development of psoriatic arthritis. We analyzed a cohort of 410 psoriasis patients who were followed over a period of 9 years. These patients did not have arthritis at baseline. The patients were assessed annually by a rheumatologist for signs of PsA. A total of 57 patients developed psoriatic arthritis during the follow-up period.

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: Ustekinumab is an antibody against the p40 molecule shared by IL-12 and IL-23. The antibody shows a favorable benfit-risk profile in the treatment of psoriasis. IL-23 is regarded a key driver in psoriasis pathology. It is speculated that antibodies against the IL-23-specific subunit p19 may produce even higher levels of clinical response than ustekinumab or the anti-TNF antagonist adalimumab. Guselkumab is the first IL-23p19 antibody to publish phase III data in psoriasis.

Psoriasis Associated With Increased Risk of Avascular Bone Death

MedicalResearch.com Interview with:

Psoriasis

Psoriasis

Hsien-Yi Chiu, MD/
Tsen-Fang Tsai, MD

Department of Dermatology, National Taiwan University Hospital
Taipei, Taiwan

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: Psoriasis is a chronic, immune-mediated disorder, characterized by red, itchy and scaly skin patches. Over the past several years, accumulating research had shown the effects of psoriasis go far deeper than the skin and psoriasis is associated with multiple comorbidities.

Psoriasis shares the inflammatory pathways and several contributing factors with avascular necrosis (AVN), a bone disease presented with death of trabecular bone and collapse of the bony structure. However, previous studies mostly focus on evaluation the increased risk of cardiovascular diseases in patients with psoriasis. No large scale studies have previously explored a potential association between psoriasis and AVN.

Our nationwide population-based cohort study investigated this risk in 28268 patients with psoriasis registered in the Taiwan National Health Insurance Research Database. The patients were matched, by age and sex, with 113072 controls without psoriasis. Both the patients and controls were followed to identify those who subsequently diagnosed with an AVN. The results showed that psoriasis was associated with a disease severity–dependent increase in avascular necrosis risk. Moreover, AVN risk was positively associated with male sex, age younger than 30 years, corticosteroid use, severe psoriasis, and concomitant psoriatic arthritis. People with severe psoriasis were 3 times more likely to develop AVN compared with the control group.

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: Over the past several years’ numerous research studies have identified comorbidities associated with psoriasis. The media has increasingly become involved with presenting these findings and patients commonly bring these concerns to their physician. The comorbidities are often presented as a relative risk, which can overestimate the effects of exposure, especially when the incidence is quite small. Comorbidities presented as attributed risk or number needed to harm might be a better measure for understanding the association between an exposure and comorbidity.

We found that although the relative risk of many diseases associated with psoriasis can be quite large, the attributed risk was small.

MedicalResearch.com: What is the background for this study?

Response: Psoriasis on the palms and soles of the feet—also known as palmoplantar psoriasis of which there are 2 variants, plaque type or pustular, —can significantly affect a person’s quality of life and is often difficult-to-treat with available treatments. Researchers in this study set out to determine the efficacy and safety of Taltz (ixekizumab) through 60 weeks among patients with moderate-to-severe plaque psoriasis with significant palmoplantar involvement. Plaque psoriasis is the most common form of psoriasis appearing as raised, red patches covered with a silvery white buildup of dead skin cells which are often painful or itchy. This study was an analysis of UNCOVER-3, a Phase 3, multicenter, double-blind, placebo-controlled trial.

In the first 12 weeks of this study, patients were randomized to receive placebo, etanercept (50 mg, twice-weekly) or 80 mg of Taltz every two weeks or every four weeks, following an initial starting dose of 160 mg. At 12 weeks, all patients received open-label Taltz every four weeks through 60 weeks.

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: In recent years, numerous studies have examined the impact of psoriasis and associated comorbidities, and found a reduced lifespan in particular among patients with severe disease. However, little is known about the impact and burden of adults with atopic dermatitis. We looked at the 10-year survival among patients hospitalized for atopic dermatitis, and compared these with patients hospitalized for psoriasis, as well as with subjects from the general population.

Our main finding was that, although the mortality risk was higher for atopic dermatitis compared with general population control subjects, the risk was significantly lower compared with psoriasis patients.

Tildrakizumab Offers Potential New Psoriasis Treatment With Quarterly Dosing

MedicalResearch.com Interview with:
Dr. Kristian Reich
Professor of Dermatology at the Georg-August-University Göttingen and inflammation specialist Dermatologikum Hamburg in Germany

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: While there is ongoing research into the causes and triggers of psoriasis, recent studies have identified IL-23 as a main driver of the IL-23/IL-17 pathway which is now thought to be the predominant pathway in the psoriasis inflammatory cascade. Selective Inhibition of IL-23 may present a new targeted strategy for treating patients with the condition. The hope for molecules selectively targeting IL-23, specifically the p19 component of the cytokine, is that newer therapies, like tildrakizumab, can more selectively control the disease allowing more patients to achieve higher and even more durable clinical responses.

The two pivotal Phase-3 studies (reSURFACE 1 and 2) evaluated the efficacy and safety of the IL-23 inhibitor tildrakizumab in adult patients with moderate-to-severe plaque psoriasis, and results through week 28 were presented for the first time as part of the Late Breaking News Session at EADV.

In the reSURFACE 1 and 2 pivotal Phase-3 studies, tildrakizumab, a selective IL-23p19 inhibitor, was evaluated against placebo and etanercept to assess efficacy, safety and tolerability. The co-primary efficacy endpoint of the two placebo-controlled studies was a) the proportion of patients with Psoriasis Area Sensitivity Index 75 (PASI 75) response at week 12 compared to placebo and the proportion of participants with a Physician’s Global Assessment (PGA) score of clear or minimal with at least a 2 grade reduction from baseline at week 12 compared to placebo. The reSURFACE 2 also included an etanercept comparator arm, with a key secondary endpoint comparing tildrakizumab and etanercept on PASI 75 and PGA. Other co-secondary endpoints of both placebo controlled studies included PASI 90 and PASI 100 responses at week 12 and PASI 75, 90 and 100 and PGA responses from baseline at Week 28.

Patients who completed 52 weeks of the core SCULPTURE and STATURE studies and re-consented to treatment were eligible for the extension, and continued the same Cosentyx dose and regimen that they were receiving in their core study. Patients did not have to achieve a PASI 75 response at the end of their core study to enroll.

A total of 642 patients entered the extension study: 168 continued on Cosentyx 300 mg every 4 weeks, 152 continued on Cosentyx 150 mg every 4 weeks, 172 continued on Cosentyx 300 mg retreatment-as-needed, and 150 continued on Cosentyx 150 mg retreatment-as-needed. At the end of Week 156, the study was open-label and patients could continue their assigned dose and regimen or switch to 300 mg every 4 weeks based on the investigator’s judgment.

Results presented at EADV focus on those patients from the SCULPTURE core study who enrolled in the extension study. The primary endpoint of this extension study was overall safety and tolerability. Secondary efficacy measures included the proportion of patients achieving PASI 75, PASI 90 and PASI 100.

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: Psoriasis is associated with accelerated cardiovascular (CV) disease; however, screening for CV risk factors in psoriasis remains low. Coronary artery calcium (CAC) score estimates the total burden of atherosclerosis. Psoriasis has been associated with increase CAC score, but how this compares to patients with diabetes, who are aggressively screened for CV risk factors, is unknown.
