RESUMEN
Background Psoriasis is a chronic inflammatory skin disease with multiple organ manifestations such as arthritis and cardiovascular diseases. While recent therapeutic advancements in systemic biologics have demonstrated efficacy against psoriasis, a complete cure has not been achieved and patients require lifelong treatment to control symptoms. Objective This study aimed to clarify the clinical characteristics of psoriasis patients treated with biologics at an extended interval. Methods This study included patients with psoriasis who were administered biologic therapy for longer than the standard interval (at least a week) and who objectively maintained favorable conditions (static Physician's Global Assessment ≤ 0 to 1). Clinical characteristics, such as body weight (BW), body mass index (BMI), and body fat percentage, were compared to those of patients who were administered biologic therapy at standard intervals. Results Among 162 Japanese patients with psoriasis, 35 were treated with biologics at extended intervals. In the group with extended treatment intervals, patients treated with interleukin (IL)-17 inhibitors (n = 15) presented statistically lower BMI than those treated with IL-23 inhibitors (n = 17) (P < 0.016). The group treated with IL-17 inhibitors at extended intervals showed significantly lower BMI and body fat percentage than the group at standard intervals (P < 0.05). Conclusion Trends in our hospital suggest that psoriasis patients with low BMI and body fat percentage can maintain good status with extended interleukin (IL)-17 inhibitor dosing intervals (static Physician's Global Assessment ≤ 0 to 1).

Psoriasis impacts various aspects of patients' health-related quality of life and is associated with sleep problems. However, research discussing the associations between interleukin-17 blockage therapies and sleep problems in patients with psoriasis is insufficient. We aimed to assess the effectiveness of brodalumab in alleviating sleep problems in real-life patients with plaque psoriasis. This analysis was part of the single-arm, open-label, multicenter, prospective, cohort study, ProLOGUE (study period October 2017-March 2020), which involved Japanese patients with plaque psoriasis. Assessments included correlation of Medical Outcomes Study Sleep Scale-Revised (MOS Sleep-R) scores (Sleep Problems Index-II [SPI-II] and MOS Sleep-R subscale scores) with multiple patient-reported outcome scores and the Psoriasis Area and Severity Index (PASI) at baseline. Additionally, change from baseline in MOS Sleep-R scores was assessed at weeks 12 and 48 of brodalumab treatment. Seventy-three patients were enrolled (male 82.2%, median age 54.0 years). At baseline, the SPI-II score correlated with the Patient Health Questionnaire-8 score (Spearman correlation coefficient [ρ] = -0.474) and weakly correlated with the Itch Numeric Rating Scale (NRS; ρ = -0.366), Skin Pain NRS (ρ = -0.275), and all Treatment Satisfaction Questionnaire for Medication-9 domain scores (ρ = 0.270, ρ = 0.303, and ρ = 0.322 for effectiveness, convenience, and global satisfaction, respectively) but did not correlate with the PASI score. The SPI-II score and MOS Sleep-R subscale scores, except the Snoring score (p = 0.0319), did not significantly change from baseline to week 12 of brodalumab treatment. In conclusion, treatment with brodalumab did not improve overall sleep problems in real-life patients with plaque psoriasis, suggesting that sleep problems require attention in daily clinical practice (Japan Registry of Clinical Trials identifier, jRCTs031180037).

Itching and skin pain are bothersome symptoms of psoriasis, but evidence is limited regarding the treatment effectiveness on these symptoms in daily clinical settings. We assessed the changes in the levels of itching and skin pain after brodalumab treatment in Japanese patients with psoriasis using patient-reported outcomes (PROs). Patients with psoriasis who have inadequate response to existing treatments were enrolled in the single-arm, open-label, multicenter, prospective ProLOGUE study and received brodalumab 210 mg subcutaneously in daily clinical practice. Psoriasis Area and Severity Index (PASI) and PRO assessments were performed at baseline and weeks 12 and 48. Seventy-three patients (men, 82.2%; median age, 54.0 years) were enrolled. The Itch Numeric Rating Scale (NRS; p < 0.0001 at weeks 12 and 48) and Skin Pain NRS (week 12, p = 0.0004; week 48, p < 0.0001) scores significantly decreased from baseline. The Itch NRS score was significantly higher in patients with a Dermatology Life Quality Index (DLQI) score of ≥2 (vs. 0/1; p < 0.0001 at weeks 12 and 48) and in patients with a Treatment Satisfaction Questionnaire for Medication-9 (TSQM-9) global satisfaction domain score of ≤70% (vs. >70%; week 12, p = 0.0120; week 48, p = 0.0348). The Itch NRS score cutoff value for achieving a PASI score of ≤2, DLQI score of 0/1, and TSQM-9 global satisfaction domain score of >70% was 1 at week 12 and 0 at week 48. Brodalumab treatment was associated with improvement in itching and skin pain in Japanese patients with psoriasis. An Itch NRS score of 0 can be a long-term treatment goal for psoriasis (Japan Registry of Clinical Trials identifier: jRCTs031180037).

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.
RESUMEN
Peristomal pyoderma gangrenosum (PPG), a variant of pyoderma gangrenosum, occurs adjacent to intestinal or urinary stomas and are typically seen in patients with active inflammatory bowel diseases (IBD). The present study evaluated 14 cases of PPG among 537 patients that had undergone ostomy surgery at Asahikawa Medical University Hospital from January 2017 to December 2021. The incidence of PPG among ostomy cases was calculated as 1.01 per 100-person-years. The median period from ostomy surgery to PPG onset was 192.5 days (36-1224 days). Significant differences in gender and ostomy subtype were observed in patients with PPG compared to all patients that had undergone ostomy surgery. IBD prevalence was comparable between groups. Topical corticosteroids or tacrolimus were sufficient for controlling PPG lesions in all cases other than one case controlled with oral prednisolone administered for a separate condition. Clinicians should be aware of recent developments in IBD therapies that may modify the risk of developing PPG. The present study results add to current knowledge of the pathogenesis of PPG.

Psoriasis is a chronic inflammatory skin disease induced by multifactorial causes and is characterized by bothersome, scaly reddish plaques, especially on frequently chafed body parts, such as extensor sites of the extremities. The latest advances in molecular-targeted therapies using biologics or small-molecule inhibitors help to sufficiently treat even the most severe psoriatic symptoms and the extra cutaneous comorbidities of psoriatic arthritis. The excellent clinical effects of these therapies provide a deeper understanding of the impaired quality of life caused by this disease and the detailed molecular mechanism in which the interleukin (IL)-23/IL-17 axis plays an essential role. To establish standardized therapeutic strategies, biomarkers that define deep remission are indispensable. Several molecules, such as cytokines, chemokines, antimicrobial peptides, and proteinase inhibitors, have been recognized as potent biomarker candidates. In particular, blood protein markers that are repeatedly measurable can be extremely useful in daily clinical practice. Herein, we summarize the molecular mechanism of psoriasis, and we describe the functions and induction mechanisms of these biomarker candidates.
RESUMEN
A tick infestation is one of the most common arthropod-related skin diseases in Hokkaido, the northernmost island of Japan. Ticks also act as an infectious disease vector for humans. Tick-borne encephalitis (TBE), a highly mortal central nervous system infection caused by TBE virus (TBEV), has sporadically occurred there recently. However, there have been no epidemiological data on the current surveillance of human tick bites and the prevalence of TBEV in human-feeding ticks. This study was performed to clarify those indeterminate issues. One hundred and fifty-three ixodid ticks feeding on humans were collected from 150 outpatients in Hokkaido during the season of April to August 2018. None of the cases showed any infectious symptoms. These ticks were morphologically identified to species, and a cytopathic assay on baby hamster kidney cells was carried out to detect TBEV from each tick. The tick collection consisted of 108 Ixodes persulcatus (one nymph and 107 adult females), 44 female Ixodes ovatus, and one female Haemaphysalis japonica. No tick extracts showed positive results of the cytopathic assay, suggesting the non-existence of TBEV in the present specimens. However, the survey to detect TBEV from human-feeding ticks is still important to monitor the occurrence of TBE, because human tick bites by I. ovatus, a possible vector of TBEV, are increasing even in the northern and eastern areas of Hokkaido.

Tildrakizumab is a high-affinity, humanized immunoglobulin G1κ, anti-interleukin-23p19 monoclonal antibody recently approved in Japan for treatment of plaque psoriasis. We report results from Japanese patients treated with tildrakizumab in the multinational, randomized, double-blind, placebo-controlled reSURFACE 1 study (clinicaltrials.gov NCT01722331). Adults with moderate to severe plaque psoriasis were randomized (2:2:1) to receive subcutaneous tildrakizumab 100 or 200 mg or placebo every 12 weeks. Placebo recipients were rerandomized to tildrakizumab 100 or 200 mg at week 12. The global study coprimary endpoints were the proportions of patients achieving 75% improvement from baseline Psoriasis Area and Severity Index (PASI 75) and Physician Global Assessment (PGA) response (0/1 with ≥2 grade reduction from baseline) at week 12. Analyses included 158 Japanese patients randomized to tildrakizumab 100 (n = 64) or 200 mg (n = 62) or placebo (n = 32). Japanese patients had higher mean baseline body surface area involvement and PASI versus all reSURFACE 1 patients. At week 12, significantly more Japanese patients receiving tildrakizumab 100 and 200 mg versus placebo achieved PASI 75 (54.7% and 54.8% vs 6.3%, respectively, both nominal p < 0.001) and PGA 0/1 response (54.7% and 56.5% vs 9.4%, respectively, both nominal P < 0.001). Response rates increased over time with maximal efficacy after 22-28 weeks; >80% of patients achieving PASI 75 or PASI 90 at week 28 and continuing tildrakizumab treatment at the same dose maintained response at week 64. From baseline to week 28, absolute PASI decreased from >12 in all patients to ≤2 in >40% and ≤3 in >50% of patients receiving tildrakizumab. Tildrakizumab was generally well tolerated with an adverse event profile similar to that of placebo. Tildrakizumab treatment was associated with durable efficacy in Japanese patients with moderate to severe plaque psoriasis despite greater baseline disease severity versus the global reSURFACE 1 population.

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.

Psoriasis is a multifactorial recalcitrant inflammatory skin disease characterized by bothersome scaly reddish plaques especially on frequently chafed body parts, such as the extensor sites of the extremities and scalp. Nonetheless, through recent advance in molecular-targeted therapies including biologics and small-molecule inhibitors, even the severest symptoms of psoriasis and its comorbidities, such as psoriatic arthritis, can be excellently treated. The superb clinical effects lead to not only remarkable alleviation of symptoms but also a deep understanding of patients' impaired "quality of life" caused by this disease. Along with the development of novel treatment options targeting various specific molecules, such as proinflammatory cytokines and signal transduction-associated molecules, clinicians have thoroughly understood the molecular mechanism of psoriasis, and discovered that the IL-23/IL-17 axis mainly depending on Th17 cell function is a crucial pathogenesis of this disease. Accumulation of knowledge about the working mechanism and clinical effect of molecular-targeted therapies is indispensable for clinicians to establish a more refined therapeutic strategy for treating psoriasis.

INTRODUCTION: Ixekizumab has demonstrated rapid onset of action, high levels of skin clearance, and improvements in quality of life in patients with moderate-to-severe psoriasis, including plaque, erythrodermic, or generalized pustular psoriasis. METHODS: This was a post hoc analysis of UNCOVER-J, a phase 3, multicenter, single-arm, open-label study of ixekizumab for treatment of Japanese patients with psoriasis. The objective was to assess the proportion of patients who achieved Dermatology Life Quality Index (DLQI) (0,1) and Itch Numeric Rating Scale (NRS) (0) at weeks 4 and 12 according to Psoriasis Area and Severity Index (PASI) percentage improvement levels. All intent-to-treat patients with plaque, erythrodermic, or generalized pustular psoriasis were analyzed. RESULTS: A total of 91 patients were treated with ixekizumab and included in the analysis. Rapid improvements in PASI at weeks 4 and 12 were associated with improvements in DLQI (0,1) response at week 4 and at week 12. Complete skin clearance (PASI 100) achieved either at week 4 or week 12 was associated with a higher Itch NRS (0) response at week 12. CONCLUSIONS: Patients with rapid improvement in clinical symptoms of psoriasis had better patient outcomes than those with slower responses. These findings highlight the clinical importance of achieving a fast response in patients with psoriasis, which may lead to better treatment outcomes. TRIAL REGISTRATION: ClinicalTrials.gov identifier, NCT01624233.
RESUMEN
Vitiligo is an autoimmune disorder resulting from the destruction of melanocytes. Several reports indicate the association between vitiligo and treatment response in advanced melanoma during immunotherapy. It has not been investigated, however, if an increase of vitiligo while on treatment with anti-programmed death 1 (PD-1) antibodies is associated with more durable responses. The aim of this study is to evaluate the correlation between the vitiligo dynamics and clinical efficacy of anti-PD-1 antibodies. This study included advanced melanoma patients who were treated with nivolumab or pembrolizumab and developed vitiligo thereafter. Correlation between vitiligo expansion (defined as an increase of lesion size at two separate time points at least 4 weeks apart) as well as vitiligo extent (body surface area [BSA] affected) and clinical efficacy based on response rate, progression-free survival and overall survival was assessed. We retrospectively reviewed 29 patients. The median time from the initiation of anti-PD-1 antibody to vitiligo onset was 4.3 months in patients who showed a response and 5.5 months in patients who showed no response (P = 0.31). Twelve patients showed vitiligo expansion, and in nine of these patients, vitiligo increased to grade 2 (covering ≥ 10% BSA). Vitiligo expansion and grade 2 vitiligo showed no improvement in treatment response (P = 0.59 and 0.25) but were associated with prolonged progression-free survival (P = 0.019 and 0.04). Grade 2 vitiligo also showed a trend for prolonged overall survival (P = 0.07). Trend of expansion and larger vitiligo extent may be predictive factors of prolonged survival during anti-PD-1 antibody in melanoma patients.
