Short-Term Correlation of the Psoriasis Area Severity Index, the Nail Psoriasis Area Severity Index, and the Dermatology Life Quality Index, before and after Treatment, in Patients with Skin and Nail Psoriasis

Impact of psoriasis disease severity and special area involvement on patient-reported outcomes in the real world: an analysis from the CorEvitas psoriasis registry

BACKGROUND

The impact of psoriasis in special areas (i.e., scalp, nails, palms, soles, genitals) on patient physical functioning, health-related quality of life (HRQoL), and work abilities has not been fully characterized. We assessed associations between disease severity and special area involvement in psoriasis symptoms, HRQoL, and work/activity impairment.

METHODS

Patients with psoriasis from the CorEvitas Psoriasis Registry who initiated systemic treatment between 04/2015-06/2020 were included. Outcomes were change from baseline in psoriasis symptoms, Dermatology Life Quality Index (DLQI), and work/activity impairment at 6 months stratified by baseline disease severity and special area involvement.

RESULTS

Among 2620 patients, increasing disease severity was associated with worsening patient-reported outcomes. Patients with (46.0%; N = 1205) versus without (54.0%; N = 1415) psoriasis in special areas reported greater HRQoL and work/activity impairment. Over 6 months, patients with unchanged or worsening disease severity had reduced HRQoL and increased symptom severity; incremental increases in patient HRQoL and decreases in symptom severity were associated with improved disease severity.

CONCLUSIONS

Higher disease severity and special area involvement was associated with worse outcomes and impaired work abilities. These data highlight the significant impact that adequate treatment of severe psoriasis and/or special area involvement may have on patient HRQoL and function.

Nail psoriasis and nail lichen planus: Updates on diagnosis and management

BACKGROUND

Inflammatory diseases of the nail, including nail psoriasis and nail lichen planus, are associated with significant disease burden and have a negative impact on quality of life. Diagnosis is often delayed, especially when patients present without cutaneous findings. Therefore, recognizing clinical signs and symptoms of inflammatory nail diseases, and initiating timely and appropriate treatment, is of utmost importance.

OBJECTIVE

We review recent studies on diagnostic techniques, discuss severity grading and scoring systems, and describe consensus treatment recommendations for nail psoriasis and nail lichen planus.

METHODS

An updated literature review was performed using the PubMed database on studies assessing diagnostic techniques or treatment modalities for nail psoriasis and nail lichen planus.

RESULTS

Recent studies on diagnostic techniques for inflammatory nail disease have focused on use of dermoscopy, capillaroscopy, and ultrasound modalities. Treatment of these conditions is dichotomized into involvement of few (≤3) or many (>3) nails. Recent psoriatic therapeutics studied for nail outcomes include brodalumab, tildrakizumab, risankizumab, deucravacitinib, and bimekizumab, while emerging treatments for nail lichen planus include JAK inhibitors and intralesional platelet rich plasma injections.

CONCLUSIONS

We emphasize the need for increased awareness and expanded management strategies for inflammatory nail diseases to improve patient outcomes.

Ixekizumab is effective in the long-term management in moderate-to-severe plaque psoriasis: results from an Italian retrospective cohort study (the LOTIXE study)

PURPOSE

Ixekizumab is a high-affinity monoclonal antibody that selectively targets interleukin (IL)-17A approved for the treatment of moderate-to-severe plaque psoriasis. The objective of this study was to describe the real-world long-term effectiveness of ixekizumab in patients with plaque psoriasis in Italy.

MATERIALS AND METHODS

A retrospective study was conducted in patients affected by moderate-to-severe plaque psoriasis who were continuously treated with ixekizumab for at least 12 months. Patient data was obtained at 4-weeks, 12-weeks and 6-, 12-, 18- and 24-months after baseline (June 2017 and September 2019) from 10 sites. Results were analyzed by complete case approach, with sensitivity analysis performed to evaluate the impact of missing data.

RESULTS

A total of 198 patients were enrolled in the study. At Month 24, 94.3% of patients achieved PASI75 response, while 85.1 and 71.8% achieved PASI90 and PASI100, respectively; and 91.1% of the patients achieved absolute PASI score ≤2. Patients experienced psoriasis improvement at 4 weeks after starting treatment, and improvement was maintained with continued ixekizumab use. The quality of life of patients also improved significantly starting at Week 12, with sustained effect in the long term.

CONCLUSION

This 24-month observational cohort study confirmed that ixekizumab is effective in the long-term management of patients with moderate-to-severe plaque psoriasis.

Itch as a critical factor in impaired health-related quality of life in patients with plaque psoriasis achieving clear or almost-clear skin: Analysis of the single-arm, open-label, multicenter, prospective ProLOGUE study

Background

Patients with psoriasis report impaired health-related quality of life (HRQoL; Dermatology Life Quality Index score ≥ 2) even after achieving clear or almost-clear skin with biologic treatment.

Objective

To assess the effectiveness of brodalumab in HRQoL improvement and the factors associated with incomplete HRQoL improvement in Japanese patients with psoriasis.

Methods

As a part of the single-arm, open-label, multicenter, prospective ProLOGUE study (Japan Registry of Clinical Trials identifier: jRCTs031180037), patients were treated with 210 mg of subcutaneous brodalumab in daily clinical practice until week 48. The absolute Psoriasis Area and Severity Index scores and patient-reported outcomes were assessed at baseline and weeks 12 and 48.

Results

Seventy-three patients (male, 82.2%; median age, 54.0 years) were enrolled. The Dermatology Life Quality Index and European Quality of Life 5-Dimension 5-Level Utility Index scores significantly improved from baseline to weeks 12 and 48. At week 48, all 13 patients with a Dermatology Life Quality Index score of ≥2 and an absolute Psoriasis Area and Severity Index score of 0 to ≤2 reported itching.

Limitations

Unclear generalizability of the results to other biologics.

Conclusion

Treatment with brodalumab improved HRQoL in patients with psoriasis. Itching may contribute to incomplete HRQoL improvement in patients who have achieved clear or almost-clear skin.

A real-world, non-interventional, prospective study of the effectiveness and safety of apremilast in bio-naïve adults with moderate plaque psoriasis treated in the routine care in Greece - The 'APRAISAL' study

BACKGROUND

Real-world data in patients with moderate psoriasis treated with apremilast is limited.

OBJECTIVES

To evaluate the effectiveness and safety of apremilast in bio-naïve patients with moderate psoriasis in real-world clinical settings.

METHODS

This was a 52-week multicenter, observational, prospective study of adult outpatients with moderate psoriasis {[10%<body surface area<20% or 10<psoriasis area severity index (PASI)<20] and 10<dermatology quality of life index (DLQI)<20} initiated on apremilast ≤7 days before enrollment. Missing data were imputed using the last observation carried forward method.

RESULTS

A total of 287 eligible patients (median age: 54.2 years; median psoriasis duration: 9.8 years) were consecutively enrolled. At baseline, the median DLQI and PASI scores were 12.0 and 11.8, respectively. The 52-week DLQI ≤5 and PASI75 response rates were 68.3% and 61.0%. At 52 weeks, 70.8% and 72.7% of the patients shifted from moderate/severe/very severe to clear/minimal scalp and palmoplantar psoriasis involvement, respectively; the pruritus severity state improved in 67.2%. The 52-week Kaplan-Meier estimated drug continuation rate was 85.3%. The adverse drug reaction rate was 19.9%.

CONCLUSIONS

Apremilast is a safe and effective treatment for bio-naïve patients with moderate psoriasis and specific psoriasis manifestations.

Treatment of nail psoriasis with pulsed dye laser versus combined pulsed dye and Nd:YAG lasers-An intrapatient left-to-right study

BACKGROUND AND OBJECTIVES

There are limited treatment options for nail psoriasis. It is important to find new therapies and improve existing ones. The aim of this study was to compare the effectiveness of pulsed dye laser (PDL) versus combined PDL and Nd:YAG lasers in patients with nail psoriasis.

METHODS

Fourteen patients (with a total of 126 nails affected by nail psoriasis) were treated with PDL (6 J/cm2, 7 mm, 0.45 milliseconds) on both hands and additionally with Nd:YAG (10 J/cm² , 6 mm, 15 milliseconds) on the right hand. Three treatment sessions were applied at 4-week intervals and patients were followed up for 6 months after the last session. Disease severity was assessed using the Nail Psoriasis Severity Index, both 8- and 32-point variant. Additionally, Dermatology Life Quality Index was assessed before and after treatment.

RESULTS

Overall, there was a statistical difference in 8- and 32-point NAPSI score before and after treatment for both hands. However, there was no statistical difference between the score for the right and left hands based on both scale variants. Some aspects of patients' lives showed improvement due to the treatment.

CONCLUSIONS

Both PDL in monotherapy and combined Nd:Yag+PDL lasers are safe and effective in treatment of nail psoriasis, although combined therapy shows no advantage over the use of a single laser.

Effectiveness and safety of Adalimumab in psoriasis and its influence on gut microbiome

Psoriasis is an inflammatory immune-mediated skin disease that significantly impacts physical and psychological well-being. Adalimumab (ADA), a tumor necrosis factor (TNF)-α antagonist, is used to treat psoriasis. This study was performed to assess the efficacy and safety of ADA, identify the fecal microbial composition of psoriasis patients, and explore the effect of ADA on the gut bacteria in psoriasis. Clinical characteristics of the 13 psoriasis patients before (BT) and after ADA treatment (AT) were collected. And total 39 fecal samples from 13 psoriasis patients (BT and AT) and 13 healthy controls were sequenced by 16S rRNA and analyzed by informatics methods. After three months' ADA treatment, physician global assessment (PGA), psoriasis area and severity index (PASI), dermatology life quality index (DLQI), state-trait anxiety inventory (STAI), and itch numeric rating scale (NRS) scores all decreased, and there were no severe adverse effects. Besides, the microbiota of the psoriasis group differed from that of the healthy group, but no microbial diversity and composition alteration were observed between psoriasis patients BT and AT. We suggested that the gut microbiome may change more slowly than skin lesions. Long-term follow-up of patients treated with ADA and further study of psoriasis based on microbiota may provide more evidence for the treatment of psoriasis.

Utility of the Dermatology Life Quality Index at initiation or switching of biologics in real-life Japanese patients with plaque psoriasis: Results from the ProLOGUE study

BACKGROUND

Plaque psoriasis significantly affects patients' health-related quality of life. To aid treatment decisions, not only objective assessment by physicians but also subjective assessment by patients is important.

OBJECTIVE

To assess the significance of Dermatology Life Quality Index (DLQI) evaluation at the time of biologics introduction in clinical practice in Japanese patients with plaque psoriasis.

METHODS

This was a single-arm, open-label, multicenter study. At baseline, Psoriasis Area and Severity Index (PASI) and DLQI scores were measured and stratified based on DLQI scores ≥6/≤5 and PASI scores ≤10/>10. Other patient-reported outcomes assessed included EQ-5D-5L, itch numerical rating scale (NRS), skin pain NRS, Generalized Anxiety Disorder-7 (GAD-7), Patient Health Questionnaire-8 (PHQ-8), Sleep Problem Index-II (SPI-II), and Treatment Satisfaction Questionnaire for Medication-9 (TSQM-9).

RESULTS

Of the 73 enrolled patients, 23 had PASI scores ≤10. Those with PASI/DLQI scores >10/≥6 had a significantly higher median PASI score than those with PASI/DLQI scores >10/≤5 (p = 0.0125). Regardless of PASI scores (>10/≤10), median itch NRS and GAD-7 scores were significantly higher in patients with DLQI scores ≥6 than in those with DLQI scores ≤5 (itch NRS, p = 0.0361 and p = 0.0086, respectively; GAD-7, p = 0.0167 and p = 0.0273, respectively). Patients with PASI/DLQI scores ≤10/≥6 had significantly higher skin pain NRS (p = 0.0292) and PHQ-8 (p = 0.0255) scores and significantly lower median SPI-II scores (p = 0.0137) and TSQM-9 Effectiveness domain scores (p = 0.0178) than those with PASI/DLQI scores ≤10/≤5.

CONCLUSION

DLQI may be useful for assessing patients' concerns that cannot be identified by PASI alone while initiating biologics or switching from other biologics in clinical practice.
