Topology of psoriasis in routine care: results from high‐resolution analysis of 2009 patients

Short-term efficacy of tildrakizumab on difficult-to-treat areas: a real-world experience

BACKGROUND

Novel biologics targeting the IL23/T-17 axis, such as tildrakizumab, have been developed to treat psoriasis. There is limited evidence on the use of tildrakizumab for the treatment of psoriasis in difficult-to-treat areas.

OBJECTIVE

Our aim was to evaluate the short-term efficacy and safety of tildrakizumab in patients with moderate-to-severe psoriasis and with the involvement of difficult-to-treat areas.

METHODS

A multicentric retrospective study was conducted on patients who initiated tildrakizumab between July 2022 and July 2023. Psoriasis Area and Severity Index (PASI), Psoriasis Scalp Severity Index (PSSI), Palmoplantar Psoriasis Area and Severity Index (ppPASI), and Nail Psoriasis Severity Index (NAPSI) were measured at baseline and after 16 weeks. The percentages of achieving a PASI75, PASI90, or PASI100 response were assessed. Dermatology Life Quality Index (DLQI) and Itch Visual Analog Scale (VAS) were measured simultaneously. Data about potential safety issues and adverse events were collected.

RESULTS

A total of 76 patients were included, and 59 (77.6%) were affected by psoriasis localized to the scalp (n = 32), palmoplantar locations (n = 13), or nails (n = 14). The mean PASI score decreased from 16.5 ± 9.8 at baseline to 1.9 ± 1.6 after 16 weeks. Tildrakizumab treatment resulted in the improvement of PSSI (19.9 ± 10.7 to 2.7 ± 4.2), ppPASI (15.4 ± 6.9 to 1.9 ± 2.3), and NAPSI (20.3 ± 16.9 to 7.6 ± 10.8) from baseline to 16 weeks, respectively. DLQI and Itch VAS also showed marked improvement.

CONCLUSIONS

Tildrakizumab is a valuable option for treating difficult-to-treat psoriasis and pruritus, with rapid onset of action.

Efficacy and safety of tildrakizumab for the treatment of moderate-to-severe plaque psoriasis of the scalp: A multicenter, randomized, double-blind, placebo-controlled, Phase 3b study

BACKGROUND

Scalp psoriasis is common and difficult to treat.

OBJECTIVE

To evaluate efficacy and safety of tildrakizumab for the treatment of scalp psoriasis.

METHODS

In this Phase 3b, randomized, double-blind, placebo (PBO)-controlled study (NCT03897088), patients with moderate-to-severe plaque psoriasis affecting the scalp (Investigator Global Assessment modified [IGA mod] 2011 [scalp] ≥3, Psoriasis Scalp Severity Index [PSSI] ≥12, ≥30% scalp surface area affected) received tildrakizumab 100 mg or PBO at W0 and W4. The primary endpoint was IGA mod 2011 (scalp) score of "clear" or "almost clear" with ≥2-point reduction from baseline at W16 (IGA mod 2011 [scalp] response). Key secondary endpoints were PSSI 90 response at W12 and W16 and IGA mod 2011 (scalp) response at W12. Safety was assessed from adverse events.

RESULTS

Of patients treated with tildrakizumab (n = 89) vs PBO (n = 82), 49.4% vs 7.3% achieved IGA mod 2011 (scalp) response at W16 (primary endpoint) and 46.1% vs 4.9% at W12; 60.7% vs 4.9% achieved PSSI 90 response at W16 and 48.3% vs 2.4% at W12 (all P < .00001). No serious treatment-related adverse events occurred.

LIMITATIONS

Only short-term data are presented.

CONCLUSION

Tildrakizumab was efficacious for the treatment of scalp psoriasis with no new safety signals.

Effectiveness, safety and impact of guselkumab on sexuality and perceived stigmatization in patients with psoriasis in routine clinical practice: Week 28 results from the prospective German multicentre G-EPOSS study

BACKGROUND

G-EPOSS is a prospective, non-interventional, German multicentre study of patients with moderate-to-severe plaque psoriasis receiving guselkumab, a therapeutic monoclonal antibody targeting interleukin-23, in a real-world setting.

OBJECTIVES

The objective of the study was to evaluate the effectiveness and safety of guselkumab, including its impact on skin, health-related quality of life (HRQoL), sexuality, and perceived stigmatization.

METHODS

Patients (≥18 years old) received guselkumab per routine clinical practice. The primary endpoint was the proportion of patients achieving absolute Psoriasis Area and Severity Index (PASI) ≤ 3 at Week (W)28. Secondary endpoint assessments over 28 weeks included the Nail Psoriasis Severity Index (NAPSI), anogenital Physician's Global Assessment (aPGA), and Dermatology Life Quality Index (DLQI). Sexuality and perceived stigmatization were assessed by patients using the Relationship and Sexuality Scale (RSS) and Perceived Stigmatization Questionnaire (PSQ), respectively.

RESULTS

Overall, 293 patients were included in the evaluable set population. Mean age and disease duration were 45.6 and 17.6 years, respectively. At baseline, mean PASI, aPGA and DLQI scores were 15.3, 2.7 and 11.3, respectively. In total, 25.9% of patients had received a prior biologic. Overall, 83.0% of patients achieved PASI ≤ 3, and 56.2%/35.1% achieved PASI ≤ 1/PASI = 0, respectively, at W28. Among those with NAPSI ≥ 1 and aPGA ≥ 1 at baseline, NAPSI = 0 and aPGA = 0 were achieved by 39.2% and 61.1% of patients, respectively, and 61.4% of patients achieved DLQI 0-1 at W28. Improvements were observed over 28 weeks across individual items of the DLQI, RSS and PSQ, indicating improved HRQoL and sex life, and decreased perceived stigmatization. Based on DLQI Question (Q)9, 53.6% of patients experienced sexual difficulties at baseline, which decreased to 12.1% at W28. DLQI Q9 responses were consistent with RSS item responses, highlighting DLQI Q9 as a sentinel for sexual impairment.

CONCLUSIONS

Guselkumab improved overall skin symptoms and HRQoL in patients with psoriasis and decreased sexual impairment and perceived stigmatization. No new safety signals were observed.

Effectiveness of Ixekizumab in Chinese Patients with Moderate-Severe Plaque Psoriasis with Special Area Involvement: Subanalysis of a Prospective, Multicenter, Observational Real-World Study

INTRODUCTION

Ixekizumab, a monoclonal antibody against interleukin-17A, demonstrated effectiveness in the treatment of psoriasis in a Chinese real-world study that was consistent with previous randomized controlled trials. Here, we report further analyses from this study to explore the effectiveness of ixekizumab for treating patients with psoriasis and the involvement of special body areas (scalp, nail, joint, palmoplantar, or genital areas).

METHODS

A multicenter, prospective, observational, single-arm, post-marketing surveillance study was conducted in patients aged ≥ 18 years with moderate-to-severe plaque psoriasis and prescribed with ixekizumab in 26 Chinese hospitals. Psoriasis Area and Severity Index (PASI) and Dermatology Life Quality Index (DLQI) scores were compared between patients with versus without psoriasis in special body areas in the overall study population and across subgroups by body area.

RESULTS

In total, 612 patients were included. At baseline, most patients (93.6%) had psoriasis involvement in at least one special body area. Overall, patients with psoriasis in special body areas reported a worse quality of life (QoL) than those without. Patients with versus without psoriasis in special body areas achieved a comparable mean reduction from baseline in PASI score (10.9 vs. 9.2 at week 2, and 16.9 vs. 14.7 at week 12, respectively) and DLQI score (6.0 vs. 4.4 at week 2, and 9.9 vs. 7.5 at week 12, respectively); a similar proportion of patients also achieved PASI 50 at week 2, and PASI 75 and PASI 90 at week 12, and a DLQI (0/1) at weeks 2 and 12. Several significantly different results were reported between subgroups, the majority of which favored patients with special body area involvement.

CONCLUSION

Most patients had psoriasis involvement in a special body area which was associated with worse QoL. Ixekizumab is similarly effective in reducing disease severity and improving QoL in patients with plaque psoriasis across different special body areas.

Efficacy of Guselkumab in Treating Nails, Scalp, Hands, and Feet in Patients with Psoriasis and Self-reported Psoriatic Arthritis

INTRODUCTION

The aim of this study was to evaluate guselkumab efficacy on regional psoriasis in a subset of psoriasis patients with a self-reported psoriatic arthritis (PsA) diagnosis.

METHODS

In the phase 3 VOYAGE-1 and -2 studies, at week (W)0, patients with moderate-to-severe psoriasis were randomized to guselkumab 100 mg, placebo → guselkumab 100 mg at W16 through W44, or adalimumab 80 mg then 40 mg at W1 through W48 (VOYAGE-1) or W24 (VOYAGE-2). Pooled efficacy outcomes, including scalp-specific Investigator's Global Assessment (ss-IGA), hands and/or feet Physician's Global Assessment (hf-PGA), fingernail PGA (f-PGA), Nail Psoriasis Area and Severity Index (NAPSI), and Dermatology Life Quality Index (DLQI), were compared (nominal p-values) through W24 in patients with self-reported PsA diagnosis. Response rates/percentage improvement from baseline were determined, employing treatment failure rules and non-response/no improvement data imputation.

RESULTS

A total of 76, 153, and 106 psoriasis patients with self-reported PsA were randomized to the placebo, guselkumab, or adalimumab groups, respectively; the baseline characteristics of patients in all three arms were comparable. At W16, a greater proportion of guselkumab- versus placebo-treated patients achieved ss-IGA 0/1 (80.6% vs. 22.7%, p < 0.001), hf-PGA 0/1 (68.9% vs. 14.8%, p < 0.001), f-PGA 0/1 (47.6% vs. 17.0%, p < 0.001), and DLQI 0/1 (45.6% vs. 2.7%, p < 0.001) responses; mean percentage NAPSI improvement was also greater with guselkumab (39.5% vs. 6.5%, p < 0.001). At W24, patients receiving guselkumab had higher ss-IGA 0/1 (77.5% vs. 58.5%, p = 0.003) and DLQI 0/1 (47.7% vs. 34.3%, p = 0.024) response rates versus those receiving adalimumab. Response rates/mean percentage improvements at W48 (VOYAGE-1) were numerically greater with guselkumab than adalimumab (e.g., NAPSI improvement: 75.6% vs. 60.9%).

CONCLUSIONS

Guselkumab-treated patients with psoriasis and self-reported PsA showed meaningful improvements in nail, scalp, and palmoplantar psoriasis.

Effectiveness, safety and quality-of-life effects of guselkumab and ustekinumab in patients with psoriasis: Week 104 results from the non-interventional, prospective, German multicentre PERSIST study

BACKGROUND

PERSIST was a prospective, non-interventional, real-world study of guselkumab and ustekinumab in adult patients with moderate-to-severe plaque psoriasis in Germany.

OBJECTIVES

To examine effectiveness, safety and quality-of-life (QoL) outcomes to Week (W) 104 of treatment with guselkumab and ustekinumab in patients with moderate-to-severe plaque psoriasis.

METHODS

Patients (≥18 years of age) received guselkumab or ustekinumab as per routine clinical practice. Outcomes to W104 were examined separately in guselkumab and ustekinumab recipients. An ad hoc exploratory analysis of outcomes with guselkumab versus ustekinumab was also performed following propensity score matching.

RESULTS

Overall, 302 and 313 patients received guselkumab and ustekinumab, respectively. Patients in both cohorts experienced improvements in disease activity and QoL that were maintained to W104, with 64.7% and 63.6% of guselkumab- and 54.6% and 64.4% of ustekinumab-treated patients achieving a Psoriasis Area and Severity Index (PASI) 90 response and a Dermatology Life Quality Index (DLQI) 0/1 score, respectively. Propensity score matching yielded well-balanced baseline characteristics except for prior biologic use, which was higher in guselkumab versus ustekinumab recipients (51.7% vs. 32.0%). Achievement of PASI ≤1 at W104 was more common in guselkumab versus ustekinumab recipients (58.7% vs. 49.7%). The W104 PASI90 response rate was 65.6% with guselkumab and 56.0% with ustekinumab; corresponding rates for PASI100 were 44.3% and 28.5%. In guselkumab recipients, response rates were higher in biologic-naïve versus biologic-experienced patients (PASI90, 77.1% vs. 53.4%; PASI100, 55.0% vs. 33.0%). A high level of response for QoL outcomes was observed for both treatments.

CONCLUSIONS

Ustekinumab and guselkumab led to improvements in physician-assessed and patient-reported outcomes that were sustained for up to 2 years, with no new safety signals identified. Following propensity score matching, greater improvements in PASI outcomes were observed with guselkumab versus ustekinumab. Improvements with guselkumab were highest in biologic-naïve patients, highlighting the value of early treatment.

Comparative effectiveness of biologics for patients with moderate-to-severe psoriasis and special area involvement: week 12 results from the observational Psoriasis Study of Health Outcomes (PSoHO)

Introduction

Psoriasis localized at the scalp, face, nails, genitalia, palms, and soles can exacerbate the disease burden. Real-world studies comparing the effectiveness of treatments for these special areas are limited.

Methods

Psoriasis Study of Health Outcomes (PSoHO) is an international, prospective, non-interventional, study comparing the effectiveness of anti-interleukin (IL)-17A biologics (ixekizumab and secukinumab) compared to other approved biologics and the pairwise comparative effectiveness of ixekizumab relative to five other individual biologics for patients with moderate-to-severe psoriasis. To determine special area involvement, physicians answered binary questions at baseline and week 12. The proportion of patients who achieved special area clearance at week 12 was assessed. Missing outcome data were imputed as non-response. Comparative treatment analyses were conducted using frequentist model averaging.

Results

Of the 1,978 patients included, 83.4% had at least one special area involved at baseline with the scalp (66.7%) as the most frequently affected part, followed by nails (37.9%), face/neck (36.9%), genitalia (25.6%), and palms and/or soles (22.2%). Patients with scalp, nail, or genital, but not palmoplantar or face/neck psoriasis, had significantly higher odds of achieving clearance at week 12 in the anti-IL-17A cohort compared to the other biologics cohort. Patients with scalp psoriasis had a 10-20% higher response rate and significantly greater odds (1.8-2.3) of achieving clearance at week 12 with ixekizumab compared to included biologics.

Conclusion

Biologics demonstrate a high level of clearance of special areas at week 12 in a real-world setting. Patients with scalp, nail, or genital involvement have significantly higher odds of clearance at week 12 with anti-IL-17A biologics compared to other biologics.

Malassezia spp. and Candida spp. from patients with psoriasis exhibit reduced susceptibility to antifungals

INTRODUCTION

Psoriasis is a chronic inflammatory disease that affects over 125 million people worldwide. Many studies have shown the importance of the microbiome for psoriasis exacerbation.

AIM

Explore the fungal load and species composition of cultivable yeasts on the skin of psoriatic patients (PP) and healthy volunteers living in a tropical area and evaluate the susceptibility to antifungals.

METHODOLOGY

A cross-sectional study with 61 participants (35 patients and 26 healthy controls) was performed during August 2018 and May 2019. Clinical data were collected from patient interviewing and/or medical records review. Samples were collected by swabbing in up to five anatomic sites. Suggestive yeast colonies were counted and further identified by phenotypical tests, PCR-REA, and/or MALDI-TOF. Susceptibility of Malassezia spp. and Candida spp. to azoles, terbinafine, and amphotericin B was evaluated by broth microdilution.

RESULTS

Nearly 50% of the patients had moderate to severe psoriasis, and plaque-type psoriasis was the most common clinical form. Yeast colonies count was significantly more abundant among PP than healthy controls. Malassezia and Candida were the most abundant genus detected in all participants. Higher MIC values for ketoconazole and terbinafine were observed in Malassezia strains obtained from PP. Approximately 42% of Candida isolates from PP showed resistance to itraconazole in contrast to 12.5% of isolates from healthy controls. MIC values for fluconazole and amphotericin B were significantly different among Candida isolates from PP and healthy individuals.

CONCLUSION

This study showed that Malassezia and Candida strains from PP presented higher MIC values to widespread antifungal drugs than healthy individuals.

Psoriatic Foot Involvement is the Most Significant Contributor to the Inconsistency Between PASI and DLQI: A Retrospective Study from China

Background

The Psoriasis Area and Severity Index (PASI) and the Dermatology Life Quality Index (DLQI) are important evaluation tools for assessing psoriasis severity and guiding treatment options. However, the scores of PASI and DLQI are often inconsistent.

Objective

This study aimed to identify the factors affecting the consistency between PASI and DLQI.

Methods

The retrospective study was based on 4125 patients. We collected the PASI, DLQI, demographic and clinical characteristics data.

Results

DLQI has a weak correlation with PASI (r=0.37; P<0.001). For the DLQI >10 groups, DLQI has almost no correlation with PASI (r=0.16; P<0.001). There are 43.60% of mild-to-moderate patients (PASI<10) in the DLQI>10 groups. Our adjusted model showed that foot (OR=2.109; 95% CI:1.581-2.815) involvement led to the greatest impairment of QoL except for PASI≥10 (OR=5.547; 95% CI:3.477-8.845). Furthermore, DLQI impairment was associated with female (OR=1.336; 95% CI:1.071-1.667); the age of 20-39 subgroup (OR=1.795; 95% CI:1.100-2.930); psoriatic arthritis (OR=1.718; 95% CI:1.208-2.443); higher income (OR = 1.408; 95% CI: 1.067-1.858); family history of psoriasis (OR=1.460; 95% CI:1.131-1.885). Moreover, the influence of exposed lesions (such as scalp; face; neck; nails; and hands) were positively associated with severely impaired QoL.

Conclusion

Dermatologists should recognize the underestimated disease burden of psoriasis patients and actively identify and treat mild-to-moderate patients with high burden. In particular, the foot was a significant contributor to the burden.

Quality of Life and Body Region Affected by Psoriasis: A Systematic Review

PURPOSE

Psoriasis is a chronic skin condition that affects approximately 1-3% of the world's population and is known to decrease patients' quality of life. However, it is yet to be ascertained whether the specific location of psoriatic lesions on the body influences one's quality of life.

METHODS

A systematic review was conducted with a search of MEDLINE, EMBASE, and Web of Science databases. Only non-case report and non-review studies with explicitly stated body regions affected by psoriasis were included in the review.

FINDINGS

Psoriatic patches and plaques in different areas of the body were not found to influence patients' quality of life to differing extents.

CONCLUSIONS

While the body of evidence is limited and presents unstandardized results, the results of this review point to the fact that all psoriatic patches and plaques decrease patients' quality of life, with neither one region doing so to a significantly greater extent than another.

Changing spectrum of hair and scalp disorders over the last decade in a tertiary medical centre

BACKGROUND

Hair- and scalp-related disorders (HSRDs) encompass a wide range of conditions that affect people of all ages.

OBJECTIVE

To evaluate the workload and trends in HSRDs at an outpatient dermatological clinic in a tertiary medical centre over a 10-year period.

METHODS

Medical records for HSRD visits to the outpatient dermatology clinic at the Sheba Medical Center, an Israeli tertiary care center, were reviewed between 1 January, 2010 and 31 December, 2020.

RESULTS

There were 10,396 HSRD visits with a new-to-follow-up visit ratio of 1:1.9. The annual number of HSRD visits, as well as their proportion out of all dermatological outpatient visits, have increased from 295 (1.24%) in 2010 to 1726 (9.44%) in 2020. The patients' mean age was 35.3 years (women 39.5 years, men 28.8 years), age range 1-87 years. Over the decade, there was a growing predominance of women with an average female-to-male ratio of 2:1. The winter season accounted for 28.7% of annual visits, followed by the autumn (25.6%), summer (24.3%) and spring (21.4%). The most prevalent HSRDs included androgenetic alopecia (30.6%), alopecia areata (19.3%), telogen effluvium (15.4%), non-scarring folliculitis (15.4%), seborrheic dermatitis (14.9%), lichen planopilaris (7.1%) and folliculitis decalvans (6.6%). Androgenetic alopecia demonstrated the highest increase over the decade examined (from 17% to 32%).

CONCLUSION

HSRDs account for a significant percentage of visits at a tertiary dermatology outpatient clinic. The number of HSRD visits has increased annually over the past decade. The recent advancement in diagnosis and treatment may account, at least in part, for the growing burden of HSRDs within dermatological ambulatory care.

Study protocol: Neuro-inflammatory parameters as mediators of the relationship between social anxiety and itch intensity: A cross-sectional, controlled laboratory study in patients with psoriasis and healthy skin controls

INTRODUCTION

Psoriasis (PSO) is a disease that in the majority of patients is accompanied by itch, which imposes a great burden and positively relates to anxiety. Social anxiety, a facet of anxiety associated with social withdrawal, may be a predictor of itch intensity in this patient group. Moreover, anxiety is linked to the secretion of neuroendocrine and inflammatory parameters such as substance P (SP), interleukin (IL)-6 and IL-17, which are also related to itch. In this research project, we investigate first, whether there is a direct relationship between social anxiety and itch intensity in patients with PSO and second whether the secretion of SP, IL-6 and IL-17 in the skin mediates this relationship. Additionally, PSO-patients are compared to healthy skin controls regarding their level of social anxiety, itch intensity and the secretion of SP, IL-6 and IL-17.

METHODS AND ANALYSES

For study 1, we aim to recruit 250 psoriasis patients and 250 healthy skin controls who complete questionnaires to assess social anxiety, itch intensity and control variables (e.g. sociodemographic variables and severity of PSO). A linear hierarchic regression will be used to determine whether social anxiety significantly contributes to itch intensity. In study 2, we plan to apply the suction blister method to 128 patients and healthy skin controls recruited from study 1 to determine SP, IL-6 and IL-17 in tissue fluid extracted from the skin. A mediation analysis will be conducted using the SPSS-macro PROCESS to test whether the relationship between social anxiety and itch is mediated by SP, IL-6 and IL-17.

Ixekizumab treatment in patients with moderate-to-severe plaque psoriasis in a real-world clinical setting

BACKGROUND

The efficacy and safety reports of ixekizumab for moderate-to-severe plaque psoriasis may vary between clinical trials and real-world studies.

AIM

To analyze the real-world data of ixekizumab therapy to evaluate its efficacy and safety and highlight the factors influencing the treatment response in the real-world scenario.

PATIENTS/METHODS

Data of 82 adult patients with moderate-to-severe chronic plaque psoriasis are included in this study. Psoriasis area severity index (PASI) 75/90/100 responses at 4, 16, 24, and 48 weeks were analyzed retrospectively from patient charts by examining demographic and clinical characteristics of the patients, especially their previous biologic experience, obesity, and involvement of hard-to-treat areas.

RESULTS

PASI75, PASI90, and PASI100 responses were achieved in 92.4%, 86.1%, and 26.6% patients at week 16 and maintained till week 48 in 92.3%, 86.5%, and 17.3% patients. PASI90 responses in obese patients were significantly lower than non-obese patients at week 4 (33.3% vs. 69.6%, p = 0.042), but this difference was minimized by week 16 (82.4% vs. 90%, p = 0.405). PASI90 responses in biologic-naive patients were significantly higher than biologic-experienced patients at week 16 (p = 0.015). Involvement of hard-to-treat areas was negatively associated with PASI90 responses at week 16 (OR: 1591805.842; 95% CI: 1.223-2071404486740.201; p = 0.047).

CONCLUSION

Ixekizumab provides an effective and safe biologic treatment option to patients with moderate-to-severe plaque psoriasis. Obesity, though it affects the early treatment response (till week 4), does not upset the overall treatment response beyond week 16. Previous biologic exposure and involvement of hard-to-treat areas are important prognostic factors for achieving high PASI responses in psoriatic patients.

Psychological (co)morbidity in patients with psoriasis: the impact of pruritus and anogenital involvement on symptoms of depression and anxiety and on body dysmorphic concerns - a cross-sectional study

OBJECTIVES

While stress plays a paramount role on the onset/exacerbation of psoriasis, via overactivation of the hypothalamic-pituitary-adrenal axis and increased release of pro-inflammatory cytokines, cutaneous inflammatory response induces, in turn, anxiety/depression symptoms, via body disfigurement and stigmatisation. The intensity of pruritus and anogenital involvement are additional risk factors for psychological comorbidity.Aims were to (1) examine the effects of intensity of pruritus and anogenital psoriasis on disease burden and psychological comorbidity and (2) identify the variables associated with the presence of clinically significant depression, anxiety, and dysmorphic concerns.

DESIGN

Cross-sectional study.

SETTING

Conducted at the University Medical Center Hamburg-Eppendorf (UKE).

PARTICIPANTS

107 patients with psoriasis (mean age = 46.3, SD = 14.6 years; 53.3% male): 64 with none/mild pruritus; 43 with moderate/severe pruritus; 31 with anogenital psoriasis; 76 not affected in the anogenital area.

PRIMARY/SECONDARY OUTCOMES MEASURES

Disease severity was assessed with Psoriasis Area and Severity Index and intensity of pruritus was rated by patients. Patient-reported outcomes included the Dermatology Life Quality Index, ItchyQoL, Patient Benefit Index, Perceived Stigmatisation Questionnaire, and Relationship and Sexuality Scale. Psychological morbidity was assessed with the Patient Health Questionnaire, Generalised Anxiety Disorder, and Dysmorphic Concern Questionnaire.

RESULTS

Patients with moderate/severe pruritus reported more quality of life impairments, depression, anxiety and dysmorphic concerns, and less treatment benefits than those with none/mild pruritus. Moderate/severe pruritus had a deleterious effect on depression and stigmatisation for patients without anogenital involvement. Less patient benefits were associated with a higher likelihood of clinically significant depression/anxiety.

CONCLUSION

Pruritus induces significant burden and psychological morbidity, particularly for patients without anogenital involvement. However, coping strategies used by patients with anogenital psoriasis might be dysfunctional for overall psychosocial adaptation. Patient-centred healthcare might be the best way to prevent psychological comorbidity.

A German Smartphone-Based Self-management Tool for Psoriasis: Community-Driven Development and Evaluation of Quality-of-Life Effects

Background

Psoriasis is a chronic disease characterized by inflammation, increased scaling, itching, and other symptoms. Psoriasis is not contagious, but patients have often felt shunned. Therefore, in addition to psoriasis symptoms, stress, anxiety, and depression can also affect quality of life (QoL). Surveys show that only a quarter of patients are satisfied with the success of their therapy. However, in addition to medical therapy, self-management can also make it easier to deal with chronic diseases like psoriasis.

Objective

The aim of this project was to develop a smartphone-based self-management tool (SMT) specifically for patients with psoriasis using a community-driven process. The impact of the SMT on QoL as well as its acceptance and usability were evaluated.

Methods

In collaboration with an internet-based self-help community, 2 user surveys were conducted to determine the requirements for a smartphone-based SMT. The surveys consisted of semistructured questionnaires asking for desired features in an SMT for psoriasis. A pilot study was conducted to evaluate QoL, acceptance, and usability. Community users were recruited to use the app for 21 days and complete the Dermatology Life Quality Index (DLQI) questionnaire at the beginning (T₀) and end (T₁). Afterward, participants were asked to complete another questionnaire on usability and ease of use.

Results

SMT requirements were collected from 97 members of an internet-based community. The SMT was built as a progressive web app that communicates with a server back end and an Angular web app for content management. The app was used by 15 participants who also provided qualitative feedback, and 10 participants answered all questionnaires. The average DLQI score was 7.1 (SD 6.2) at T₀ and 6.9 (SD 6.6) at T₁. The minimal required sample size of 27 was not reached.

Conclusions

The high degree of community participation in the development process and the responses during the requirement engineering process indicated that there is a general need for an independently developed SMT for patients with psoriasis. However, the feedback received after app use shows that the SMT does not meet the needs of the community. It can be concluded that a more customizable app is needed. The focus and needs of the users were very heterogeneous. Similar developments and research could benefit from the findings of this project.

Prevalence of Tobacco Smoking and Its Association With Disease Severity Among Patients With Psoriasis in China: A Cross-Sectional Study

Introduction

Tobacco smoking is associated with the onset and severity of psoriasis, and understanding the prevalence of tobacco smoking among patients with psoriasis is critical due to its high physical and mental influence and heavy disease burden. However, evidence on the association between tobacco smoking and psoriasis severity is still limited in China.

Objectives

The objective of this study was to examine the prevalence of tobacco smoking and explore the association between tobacco smoking and diseases severity among patients with psoriasis.

Methods

A total of 4,529 patients with psoriasis in 200 selected hospitals were recruited in China between January 2020 and September 2021. Detailed information covering demographic feature, tobacco smoking, and psoriasis history were collected through an electronic questionnaire, and clinical data were extracted from the health information system (HIS). SAS 9.4 was used for data analysis, and a p-value of <0.05 was considered statistically significant.

Results

The prevalence of tobacco smoking was 30.8%, with 24.6% for current smoking. The average Psoriasis Area and Severity Index (PASI) score for patients with psoriasis was 9.4, with male patients having a higher PASI score than female patients. The odds ratio (OR) of former tobacco smoking prevalence was 1.5 [95% confidence interval (CI): (1.0–2.3)] for PASI score (3.0–7.0), 2.2 for PASI score (7.1–13.0), and 4.2 for PASI score >13, when compared with patients with PASI score < 3.0. Similarly, the OR of current tobacco smoking prevalence was 1.8 [95% CI: (1.5–2.2)] for PASI score (3.0–7.0), 1.9 for PASI score (7.1–13.0), and 3.1 for PASI score >13, when compared with patients with PASI score <3.0. The Spearman correlation analysis indicated that both tobacco smoking intensity and smoking duration were positively correlated with psoriasis severity (p < 0.05).

Conclusion

The prevalence of tobacco smoking was high, especially among male patients with psoriasis and those with senior high education. Tobacco smoking was positively associated with psoriasis severity; moreover, both smoking intensity and smoking duration were positively correlated with the severity of psoriasis in a dose-dependent fashion.

Patient perceptions of psoriatic disease in Japan: Results from the Japanese subgroup of the Understanding Psoriatic Disease Leveraging Insights for Treatment (UPLIFT) survey

The population‐based Understanding Psoriatic Disease Leveraging Insights for Treatment (UPLIFT) survey was designed to better understand patient and dermatologist perceptions of the disease burden of psoriasis (PsO) and their treatment expectations. UPLIFT was a cross‐sectional, quantitative, online survey conducted in Europe, North America, and Japan between 2 March and 3 June 2020. In Japan, 391 patients reporting a diagnosis of PsO and/or psoriatic arthritis (PsA) were surveyed (75% had PsO alone, 23% had PsO and PsA, and 2% had PsA alone). Self‐reported body surface area (BSA) data were available for 309 Japanese patients, with the majority (80%) reporting PsO‐involved BSA ≤3 palms. Current symptoms of PsO were rated as moderate or severe by 43% of Japanese patients with BSA ≤3 palms, and severe by 44% of patients with BSA 4–10 palms. PsO frequently occurred in ≥1 special areas, most commonly the scalp in 76% of Japanese patients with BSA ≤3 palms, and ≥90% of those with BSA ≥4 palms. Furthermore, musculoskeletal symptoms in 42% of patients with PsO alone were suggestive of PsA. Whereas Japanese patients with BSA ≤3 palms mainly reported receiving topical therapy alone (34%) or no treatment (32%), 64% patients with BSA 4–10 palms reported receiving systemic therapy. Overall, 21% of Japanese patients with self‐perceived mild symptoms of PsO and 48% of patients with special area involvement experienced at least a moderate impact of disease on quality of life (Dermatology Life Quality Index score >5). Moreover, patients and dermatologists differed in their perceptions of determinants of PsO severity and treatment, and office visit discussions. In general, these findings from the Japanese subgroup of the UPLIFT survey demonstrated that a high proportion of patients perceived their symptoms to be moderate or severe irrespective of the level of skin involvement, suggesting a persistent unmet treatment need.

Efficacy of Tildrakizumab for the Treatment of Difficult-to-Treat Areas: Scalp, Nail, Palmoplantar and Genital Psoriasis

Tildrakizumab, an IL-23 inhibitor, is effective and safe for the improvement of moderate-to-severe chronic plaque psoriasis. However, little evidence is available on the use of this biologic in psoriasis in difficult-to-treat locations. In this retrospective analysis, we treated patients with 100 mg tildrakizumab at Day 0, after 4 weeks and every 12 weeks thereafter. Disease severity and treatment response was assessed by the Psoriasis Area and Severity Index (PASI), the static Physician’s Global Assessment of Genitalia (sPGA-G), the Psoriasis Scalp Severity Index (PSSI), Nail Psoriasis Severity Index (NAPSI) and the Palmoplantar Psoriasis Area and Severity Index (ppPASI) at baseline and after 4, 12 and 28 weeks. We followed 18 patients (mean age 49.1 ± 12.7 years, 61.1% male) with psoriasis localized to the genital region (N = 7), scalp (N = 6), nails (N = 5) and palmar/plantar areas (N = 7). PASI score decreased from 11.5 at baseline to 3.1 and 2.4 at 12 and 28 weeks. Tildrakizumab treatment decreased sPGA-G (3.3 to 0.2), PSSI (36.2 to 2.7), NAPSI (48.4 to 15.7) and ppPASI (5.3 to 0) from baseline to 28 weeks, respectively. Data from this real-life retrospective analysis shows that tildrakizumab is an effective option for the management of psoriasis in difficult-to-treat areas.

Chronic Plaque Psoriasis in Poland: Disease Severity, Prevalence of Comorbidities, and Quality of Life

The epidemiology of psoriasis has not been widely assessed in Polish population so far. This study aimed to investigate psoriasis epidemiological situation by evaluating disease course and severity, management, comorbidities, environmental factors, and knowledge about this disorder among psoriatic patients in Poland. A cross-sectional cohort population-based study enrolled 1080 psoriatic patients and 1200 controls. The mean age of psoriasis onset was 27.6 years; 78.24% had type I psoriasis. Positive family history of psoriasis was reported in 44.81% of patients, whereas itch was reported in vast majority of patients (83.33%). Based on PASI score moderate psoriasis was the most common in studied group (mean 12.63 ± 9.33, range 0−67.2). The DLQI score (12.01 ± 7.41, range 0−30.0) indicated a very large effect of psoriasis on the quality of life. Hypertension was the most prevalent comorbidity (33.80%), followed by obesity (16.85%) and dyslipidemia (11.85%). Stress was the foremost cause of disease exacerbation (66.20%); however, infections (44.07%) and seasonal changes (45.09%) had also an impact on the course of psoriasis. Psoriatic patients were more often smokers (37.59%) vs. general population (27.50%; p < 0.0001). In conclusion, epidemiological studies help clinicians in better disease and patient understanding, which may translate into better management and patient compliance.

Moderate Psoriasis in Clinical Practice: French Expert Consensus Using a Modified Delphi Method

INTRODUCTION

Despite the existence of multiple assessment scores for psoriasis severity, skin disease with limited skin lesions but significant impairment of quality of life can be difficult to classify, leading to under- or overtreatment. Our objective was to obtain consensus on clinical criteria to classify psoriasis severity in French clinical practice, with a focus on moderate disease, using a modified Delphi method.

METHODS

A steering committee (SC) formulated a 22-item questionnaire to classify moderate psoriasis. An independent panel of French dermatologists indicated their level of agreement for each item using a 9-point Likert scale (round 1). Items without a strong consensus were modified and included in round 2. For each item, strong consensus was defined as at least 75% of scores ≥ 7 and median score ≥ 8; good consensus was defined as at least 75% of scores ≥ 7 or median score ≥ 8.

RESULTS

Of 80 dermatologists who agreed to participate, 47 (59%) responded in round 1. All participants from round 1 responded in round 2. Fifteen (68%) items achieved strong consensus and four (18%) achieved good consensus. For psoriasis severity, several clinical dimensions assessed both by the physician (location, symptoms, temporality, previous treatments) and the patient (perception, physical and psychological impairment) obtained consensus. The following were considered sufficient to confirm that psoriasis is at least at a moderate stage: limited involvement but with an impact on patient/family quality of life; involvement of a special area; presence of uncontrolled symptoms (scaling, bleeding, pruritus, insomnia); accumulation of mild intensity symptoms; presence of burdensome onychodystrophy; failure of well-applied topical treatments. There was strong consensus that recognition of moderate psoriasis should lead to reassessment of topical treatments.

CONCLUSION

Our modified Delphi panel suggests detailed criteria to help physicians classify patients with psoriasis which is at least at a moderate stage, which could, in turn, improve treatment in these patients.

Quality-of-Life Outcomes, Effectiveness and Tolerability of Apremilast in Patients with Plaque Psoriasis and Routine German Dermatology Care: Results from LAPIS-PSO

INTRODUCTION

Psoriasis is a systemic inflammatory disease characterised by pruritic skin lesions that impair quality of life (QOL). Long-Term Documentation of the Utilization of Apremilast in Patients with Plaque Psoriasis under Routine Conditions (LAPIS-PSO; ClinicalTrials.gov: NCT02626793) was a 52-week, prospective, multicentre, observational cohort study conducted in real-world dermatology clinical settings in Germany. We evaluated physician- and patient-reported outcomes for QOL, effectiveness and tolerability in patients with moderate to severe psoriasis vulgaris in LAPIS-PSO.

METHODS

The primary endpoint was the percentage of patients achieving Dermatology Life Quality Index (DLQI) score ≤ 5 or ≥ 5-point improvement from baseline in DLQI score at visit 2 (~ 4 months after baseline). Secondary endpoints included assessments of symptoms and disease severity. Tolerability was evaluated based on adverse events (AEs). A pre-defined subgroup analysis based on baseline Physician's Global Assessment (PGA) score (2 or 3 versus 4) was performed. Data were examined descriptively through visit 5 (~ 13 months) using the last-observation-carried-forward (LOCF) approach and data as observed.

RESULTS

In total, 257 patients were included for efficacy assessment. On LOCF analysis, most patients achieved the primary endpoint at visit 2 (66.5%); DLQI response was maintained at visit 5 (72.4%). Earlier treatment response was observed in patients with a PGA score of 2 or 3 versus 4 (visit 1 PASI ≤ 3: 20.5% versus 10.8%). Adverse events were consistent with the known safety profile of apremilast.

CONCLUSIONS

In routine clinical care in Germany, patients with moderate to severe plaque psoriasis benefited from apremilast treatment up to ~ 13 months, consistent with findings from clinical trials, with a good safety profile.

Evolution of Patient Perceptions of Psoriatic Disease: Results from the Understanding Psoriatic Disease Leveraging Insights for Treatment (UPLIFT) Survey

INTRODUCTION

Since the 2012 Multinational Assessment of Psoriasis and Psoriatic Arthritis (MAPP) survey, several systemic treatments for psoriasis (PsO) and/or psoriatic arthritis (PsA) have been approved. The population-based UPLIFT survey was conducted to understand how perceptions of treatment-related outcomes have evolved, particularly for patients with mild to moderate PsO and/or PsA and their dermatologists.

METHODS

This population- and web-based survey was conducted from 2 March to 3 June 2020, in North America, Europe, and Japan. Adults with self-reported healthcare practitioner (HCP)-diagnosed PsO and/or PsA and dermatologists who spent > 50% of time treating patients and treated ≥ 20 patients with PsO, including plaque PsO, per month were included. Patient participants were recruited at random from online panels; dermatologists were recruited randomly from representative physician panels.

RESULTS

Of 264,054 patient responses, 3806 who self-reported an HCP diagnosis of PsO and/or PsA were included in the final sample; 67% had PsO alone, 28% had PsO and PsA, and 5% had PsA alone. The estimated population prevalence of psoriatic disease was 7% (PsO only: 4%; PsO and PsA: 2%; PsA only: 1%). Most patients (78%) reported PsO-involved body surface area (BSA) ≤ 3 palms, and ~ 90% or more reported itching, redness, flaking, and scales. Many PsO patients without diagnosed PsA reported musculoskeletal symptoms suggestive of PsA (63%). Across BSA categories, approximately one in four patients was not currently receiving treatment and > 50% had Dermatology Life Quality Index score > 5. Patients and dermatologists had different perceptions of PsO severity, office visit discussions, treatment goals, and treatment satisfaction. The survey was conducted during the coronavirus disease 2019 (COVID-19) pandemic, which could have affected assessments of patient-reported outcomes and ability to have in-person HCP visits.

CONCLUSIONS

Patients with PsO and PsA in UPLIFT reported high disease burden, including patients with limited skin involvement. An opportunity exists to align patient and dermatologist perceptions to optimize management of PsO and PsA.

The hair follicle-psoriasis axis: Shared regulatory mechanisms and therapeutic targets

It has long been known that there is a special affinity of psoriasis for the scalp: Here, it occurs most frequently, lesions terminate sharply in frontal skin beyond the hair line and are difficult to treat. Yet, surprisingly, scalp psoriasis only rarely causes alopecia, even though the pilosebaceous unit clearly is affected. Here, we systematically explore the peculiar, insufficiently investigated connection between psoriasis and growing (anagen) terminal scalp hair follicles (HFs), with emphasis on shared regulatory mechanism and therapeutic targets. Interestingly, several drugs and stressors that can trigger/aggravate psoriasis can inhibit hair growth (e.g. beta-blockers, chloroquine, carbamazepine, interferon-alpha, perceived stress). Instead, several anti-psoriatic agents can stimulate hair growth (e.g. cyclosporine, glucocorticoids, dithranol, UV irradiation), while skin/HF trauma (Köbner phenomenon/depilation) favours the development of psoriatic lesions and induces anagen in "quiescent" (telogen) HFs. On this basis, we propose two interconnected working models: (a) the existence of a bidirectional "hair follicle-psoriasis axis," along which keratinocytes of anagen scalp HFs secrete signals that favour the development and maintenance of psoriatic scalp lesions and respond to signals from these lesions, and (b) that anagen induction and psoriatic lesions share molecular "switch-on" mechanisms, which invite pharmacological targeting, once identified. Therefore, we advocate a novel, cross-fertilizing and integrative approach to psoriasis and hair research that systematically characterizes the "HF-psoriasis axis," focused on identification and therapeutic targeting of selected, shared signalling pathways in the future management of both, psoriasis and hair growth disorders.

Disease burden, symptoms, and use of analgesics in patients with psoriasis with or without psoriatic arthritis: A cross-sectional study

BACKGROUND

Patients with psoriasis have an impaired quality of life and higher use of analgesics than the general population. Whether such use is due to skin pain or a consequence of joint pain resulting from psoriatic arthritis (PsA) is not clear.

OBJECTIVES

To assess symptoms, disease burden, and use of analgesics in patients with psoriasis with and without PsA.

METHOD

Symptoms, general health (EurQol 5-dimension and 5-levels), and use of analgesics were assessed in patients with psoriasis and the general population from the Danish Skin Cohort.

RESULTS

We included 4016 patients with psoriasis (847 with concomitant PsA) and 3490 reference individuals. For patients with psoriasis having PsA, itch, skin pain, and/or joint pain was associated with worse general health. Use of opioids within 12 months was observed among 9.0% of the general population, 14.2% of patients with psoriasis without PsA, and 22.7% of patients with concomitant PsA. Of the symptoms, only joint pain was associated with use of analgesics (odds ratio, 3.72 (2.69-5.14); P < .0001).

LIMITATIONS

Cross-sectional design.

CONCLUSION

Patients with psoriasis (especially concomitant PsA) have a higher use of analgesics compared with the general population, which appears to be a result of increased joint pain.

Effect of baseline disease severity on achievement of treatment target with apremilast: results from a pooled analysis

BACKGROUND

Treating to absolute treatment targets rather than relative measures such as Psoriasis Area and Severity Index (PASI)-75 is emerging as an important clinical concept included in psoriasis guidelines and clinical practice. Achieving treatment targets is associated with achievement of long-term outcomes.

OBJECTIVE

To evaluate the relationship between psoriasis severity, disease characteristics and achievement of PASI ≤2 with apremilast in a pooled analysis of the phase 3 ESTEEM 1 and 2 (NCT01194219 and NCT01232283), phase 3b LIBERATE (NCT01690299) and phase 4 UNVEIL (NCT02425826) clinical trials.

METHODS

Pooled data from patients with moderate-to-severe plaque psoriasis randomized to apremilast 30 mg BID were analysed by baseline PASI quartiles (Q1: 2.4-13.1; Q2: 13.2-15.9; Q3: 16.0-20.0; Q4: 20.1-57.8). Assessments included PASI, Dermatology Life Quality Index (DLQI), Scalp Physician's Global Assessment (ScPGA; ScPGA ≥1) and target (worst) Nail Psoriasis Severity Index (NAPSI; NAPSI ≥1).

RESULTS

Of 1062 patients, 963 had ScPGA ≥1 and 643 had NAPSI ≥1; 771 patients with baseline and Week 32 PASI assessments were included in analyses of Week 32 PASI target achievement. Rates of PASI ≤2 at Week 32 were greater in lower PASI quartiles (Q1: 43.5%; Q2: 31.2%; Q3: 26.8%; Q4: 18.4%). Most patients achieving PASI ≤2 target (83.6%) achieved DLQI ≤5 at Week 32; 59.3% of patients who did not achieve PASI ≤2 target achieved DLQI ≤5. At Week 32, mean improvements in ScPGA and NAPSI were similar with more moderate vs. more severe disease (ScPGA, range: 1.1-1.4; NAPSI, range: 1.6-2.5). In a subgroup analysis, achievement of PASI ≤2 target was higher in the lowest PASI quartile and with disease duration <5 years.

CONCLUSIONS

Greater achievement of PASI ≤2 was observed in patients with more moderate vs. more severe skin disease. Apremilast may be particularly beneficial in more moderate disease early in the treatment paradigm.

Reaching Treatment Goals in Psoriasis with Conventional Systemic Drugs: How Long Are We Willing to Wait?

OBJECTIVES

The purpose of this study was to investigate the attainment of treatment goals according to the European Consensus Programme (ECP-TGs) from 2011 in patients with moderate to severe psoriasis (Pso) treated with the first conventional systemic therapy and to identify factors that might compromise the attainment of these treatment goals.

METHODS

In a multicenter, prospective observational study, patients with moderate to severe Pso, defined as either body surface area (BSA) >10% or psoriasis area severity index (PASI) >10 and dermatology life quality index (DLQI) >10, received a conventional systemic therapy that could be modified at each follow-up visit over the course of 18 months. All subjects signed an informed consent form, were ≥18 years of age as well as systemic therapy naïve, and had regular study visits at months 3, 6, 9, 12, and 18 after baseline. Among others and in addition to demographic and disease-related characteristics at baseline, we documented BSA, PASI, DLQI, and the physician-reported attainment of treatment goals at each follow-up visit. Factors related to a failure in achieving the ECP-TGs (i.e., either Δ PASI ≥75 or Δ PASI ≥50 and <75 with a DLQI ≤5) at month 18 were investigated by multiple logistic regression. Descriptive results are presented as the mean ± SD for interval data, and absolute as well as relative frequencies for nominal data. For this part of the analysis, data at baseline and months 6, 12, and 18 are presented.

RESULTS

A total of 133 Pso patients with a mean age and disease duration of 49.5 ± 14.4 and 15.6 ± 12.8 years, respectively, were included in the analysis; 54.1% (n = 72) were male. The mean baseline disease-related outcomes were: BSA: 21.5 ± 15.8%, PASI: 13.7 ± 7.14, and DLQI: 12.0 ± 6.11. The most common conventional systemic therapies initiated at baseline were fumaric acid esters (n = 74, 55.6%), methotrexate (n = 46, 34,6%), and ciclosporin (n = 6, 4.5%). The ECP-TGs were achieved by 58 patients (43.6%) at month 6, 86 patients (64.7%) at month 12, and 97 patients (72.9%) at month 18. An optimized reduced logistic regression model identified the presence of onycholysis/nail dystrophy at two or more digits to be associated with failing to attain the ECP-TGs (OR 10.7, 95% CI 2.5-46.7, p = 0.002).

CONCLUSION

Patients with onycholysis/nail dystrophy at two or more digits were identified as having a higher risk of not achieving ECP-TGs under conventional systemic therapy. The ECP-TGs from 2011 were attained by 43.6% of our patients 6 months after starting conventional systemic therapies. In the era of safe, fast, and efficacious Pso therapies, much higher treatment goals might be achieved during therapy. New treatment goals are only of use if patients and dermatologists strive to attain them.

Sex-related impairment and patient needs/benefits in anogenital psoriasis: Difficult-to-communicate topics and their impact on patient-centred care

Genital psoriasis affects 2-5% of psoriasis patients; generalised plaque or intertriginous psoriasis also affects the genital area in 29-40% of cases. Anogenital psoriasis has been associated with significant quality of life impairments, but little is known about specific patient needs/treatment goals. This study aimed to examine the overall and sex-related disease burden, patient needs and treatment benefits in patients with anogenital psoriasis, compared to patients with psoriasis not affecting the anal/genital areas. Within the cross-sectional nationwide survey, 2,009 participants were consecutively recruited in 157 randomly assigned German dermatology practices and clinics, according to the following inclusion criteria aged 18 years or over; diagnosis of psoriasis vulgaris; ability to answer the questionnaires; and written informed consent. Based on a high-resolution grid on the topical distribution of psoriasis, two groups were formed: anogenital psoriasis (n = 622) and comparison group (n = 1,303). Clinical severity was assessed by the Psoriasis Area and Severity Index (PASI). Patients completed the EuroQoL visual analogue scale (EQ VAS), the Dermatology Life Quality Index (DLQI), and the Patient Benefit Index (PBI). Patients with anogenital psoriasis had higher PASI (13.0±10.6 vs. 8.9±7.6, P < 0.001) and more DLQI impairments (8.9±6.9 vs. 7.0±6.2, P = 0.002) than controls. At the item-level, they also reported more sex-related DLQI impairments (DLQI-i9: 0.5±0.8 vs. 0.3±0.7, P < 0.001) and treatment needs (PBI-i17: 2.2±1.8 vs. 1.9±1.8, P = 0.001). A great percentage of missing/not-relevant responses was found for sex-related items (23.3-41.9%). These results suggest that the assessment of sex-related impairments and treatment needs should be prioritised in patients with anogenital psoriasis. Questionnaires may be used as a less uncomfortable way for patients to discuss their genital lesions and sexual function during healthcare visits. However, the great percentage of missing/not-relevant responses to sex-related items calls for in-depth assessments and effective patient-physician communication regarding these sensitive topics.

Epidemiology of psoriasis in hard-to-treat body locations: data from the Danish skin cohort

BACKGROUND

Having psoriasis in hard-to-treat areas, i.e. the scalp, face, palms, soles, nails, and genitals, respectively, can impair patients' quality of life. We investigated the prevalence of hard-to-treat body locations of psoriasis, and described patients' clinical and demographic characteristics, and quality of life impacts in a population-based cohort.

METHODS

We performed a cross-sectional study using a total of 4016 adults (≥18 years) with psoriasis from the Danish Skin Cohort. Groups were compared to patients without involvement of hard-to-treat areas.

RESULTS

The most frequently affected hard-to-treat area was the scalp (43.0%), followed by the face (29.9%), nails (24.5%), soles (15.6%), genitals (14.1%), and palms (13.7%), respectively. Higher prevalence was generally seen with increasing psoriasis severity. Among all patients 64.8, 42.4, and 21.9% of patients had involvement of ≥1, ≥2, or ≥ 3 hard-to-treat areas. Those with involvement of certain hard-to-treat areas such as hands, feet, and genitals had clinically relevant DLQI impairments. Having involvement of one hard-to-treat area was significantly associated with other hard-to-treat areas affected even after adjusting for age, sex, and psoriasis severity.

CONCLUSION

Psoriasis commonly affects hard-to-treat locations, even in patients with mild disease. For some of these areas, patient-reported disease burden, e.g. as measured by DLQI, is impaired.

Disease burden and patient needs and benefits in anogenital psoriasis: developmental specificities for person-centred healthcare of emerging adults and adults

BACKGROUND

Establishing romantic relationships involving cohabitation and/or sexual intercourse is an overriding task for many people during emerging adulthood, i.e. from their late teens through the twenties. The diagnosis of anogenital psoriasis may hinder social/intimate relationships, resulting in higher disease burden in this age group.

OBJECTIVES

To compare the disease burden and patient needs/benefits between emerging adults (18-30 years) and adults (>30 years) with psoriasis, with and without anogenital involvement; and to identify sociodemographic/clinical variables accounting for better patient-reported outcomes.

METHODS

Patients aged ≥18 years with psoriasis vulgaris were recruited within a cross-sectional nationwide survey randomly assigning 157 dermatology practices/clinics in Germany. Anogenital involvement was established based on a high-resolution grid on the topology of psoriasis. The main outcome measures were the Psoriasis Area and Severity Index (PASI), the EuroQoL visual analogue scale (EQ-VAS), the Dermatology Life Quality Index (DLQI) and the Patient Benefit Index (PBI).

RESULTS

Participants were 1921 patients: 173 emerging adults and 1749 adults >30 years. Anogenital involvement was observed in 621 patients (32.3%). Patient with anogenital psoriasis reported decreased health and more QoL impairments compared with those without anogenital lesions. Emerging adults presented more QoL impairments and less treatment benefits than older patients, and they were more prone to underrate a wide range of needs, except when the anogenital area was affected. Beyond anogenital involvement and higher disease severity, less treatment benefits were associated with more QoL impairments, particularly for emerging adults.

CONCLUSIONS

The developmental instability of many emerging adults may result in difficulties to establish/adhere to treatment goals and thus in decreased perception of treatment benefit and more QoL impairments. Anogenital involvement is a risk factor for increased disease burden regardless of age. Assessing anogenital involvement in all patients and helping younger patients to define/adhere to treatment goals should be prioritized in patient-centred healthcare for psoriasis.

Vitamin D in trichology: a comprehensive review of the role of vitamin D and its receptor in hair and scalp disorders

Vitamin D plays an important role in maintaining the homeostasis of various biological systems. Beside its well-known function in calcium and phosphate metabolism, it plays a major role in pathophysiology of skin and adnexa. Indeed, vitamin D, through its receptor (VDR), decreases keratinocyte proliferation, improves their differentiation and modulates both cutaneous innate (antimicrobial activity and antigen presentation) and adaptative immunity (T and B lymphocyte function). The maintenance of normal hair is dependant on the integrity of the dermis, epidermis and hair cycles. Beside its effect on epidermal differentiation, VDR plays a vital role in preserving the hair follicle integrity. While the relevance of VDR has been fully elucidated, the real value of vitamin D in the hair follicle cycle still remains uncertain. To date, results in literature remain contradicting and far from definitive; still, the role of vitamin D in the various forms of human alopecia is likely to be significant. The aim of this article is to review evidence about the role of vitamin D and its receptor in trichology, with a focus on scarring and non-scarring alopecia and in particular on the potential therapeutic use of Vitamin D for hair and scalp disorders.
