Abstract
BACKGROUND Formation of anti-drug antibodies (ADAs) against biologics is an important cause of psoriasis treatment failure. OBJECTIVE This study aimed to summarize the characteristics of ADAs formation under different biological therapies and the influence of ADAs on the clinical effects and safety of biologics in patients with psoriasis. METHODS PubMed, Embase, and Web of Science databases were searched from their inception to August 2022. Studies on biologics that assessed ADA levels in patients with psoriasis were included. The Cochrane risk-of-bias tool was used to assess the quality of randomized controlled trials (RCTs), the Newcastle-Ottawa Quality Assessment Scale (NOS) for case-control and cohort studies, and the Joanna Briggs Institute (JBI) critical appraisal checklist for single-arm studies. We calculated the pooled incidence with a random-effects model using R software. Subgroup analyses revealed that differences in patient characteristics, disease conditions, study design, and immunoassays may influence ADA generation and detection. RESULTS The analysis included 86 studies, with a total population of 42,280 individuals. The pooled ADA rates were 0.49%, 2.20%, 2.38%, 4.08%, 7.38%, 7.94%, 14.29%, 21.93%, 29.70%, 31.76%, and 39.58% for secukinumab, etanercept, brodalumab, ustekinumab, tildrakizumab, guselkumab, ixekizumab, risankizumab, infliximab, adalimumab, and bimekizumab, respectively. >70% (95% CI, 0.71-0.81) of ADAs against adalimumab were neutralizing antibodies, and over 70% of ADAs against secukinumab and brodalumab were transient. Concomitant methotrexate therapy with tumor necrosis factor-α (TNF-α) inhibitors decreased ADA levels. Lower infliximab doses and intermittent therapy with interleukin (IL)-23 p19 inhibitors increased ADA formation. Additionally, ADA formation under treatment using TNF-α inhibitors and IL-12/23 p40 inhibitors was associated with lower response rates or serum drug levels, but only high ADA titers reduced the clinical effects of IL-17 inhibitors. The occurrence of IL-23 p19 and TNF-α inhibitors has been linked to injection-site reactions. CONCLUSIONS Among the 11 biologics, secukinumab, etanercept, and brodalumab resulted in the lowest ADA formation rates. Immunogenicity contributes to lower biological efficacy and a higher likelihood of injection-site reactions. Low doses, intermittent treatment may increase ADA formation. An appropriate biologic should be selected based on the ADA formation rate and course of treatment.

Abstract
Generalized pustular psoriasis (GPP) is a rare, chronic, and severe skin disorder characterized by the eruption of non-infectious pustules on an erythematous background often associated with systemic symptoms. It may appear in association with plaque psoriasis or occur in previously healthy individuals. It differs from psoriasis vulgaris in clinical presentation, immunopathogenesis, histology, and therapeutic strategies. Overexpression of interleukin 36 (IL-36) or a loss-of-function mutation of IL-36 receptor antagonist (IL-36RA) are thought to play a pivotal role in the pathogenesis of this disease. There are currently no globally approved guidelines for the treatment of GPP, and the therapies used so far, with variable results, have given unsatisfactory results. Spesolimab, a selective humanized antibody against the IL-36 receptor that blocks its activation, is the first biologic drug approved in Europe in December 2022 for the treatment of GPP flares. It represents a promising therapy, demonstrating efficacy in reducing disease severity and improving patient outcomes. In our review, we have analyzed the latest advancements and findings regarding the efficacy and safety of spesolimab in the context of GPP management.

Abstract
Generalized pustular psoriasis (GPP) is a potentially life-threatening skin disease. Although several medications are approved for treating GPP in Japan, there are limited data on real-world treatment patterns or drug survival (the number of prescribed days of treatment). This retrospective cohort study describes drug survival and treatment patterns of patients with newly diagnosed GPP (International Classification of Diseases, 10th Revision code L40.1), and ≥1 year of follow-up, using de-identified claims data (Medical Data Vision Co., Ltd.) from January 2016 to August 2021. Most (97.0%) of the 434 Japanese patients received first-line therapy of etretinate (26.4%), topical medications (14.7%), or cyclosporin (14.3%); 80.0% and 60.1% of patients received a second and third line of therapy (LOT), respectively. Use of etretinate (12.6%) and cyclosporin (5.9%) decreased in second-line therapies, whereas use of biologics (interleukin [IL]-17, 14.3%; IL-23 inhibitors, 7.6%) and topical medications (22.1%) increased or remained consistent. Approximately 50% of biologics were prescribed in combination with systemic medications or systemic corticosteroids. Median (range) time to next therapy (TTNT) was 2.8 (0.03-48.07) months for first-line therapy and 3.3 (0.03-52.97) months for all other LOTs. TTNT was longer for combination therapies (up to 16.5 months) compared with monotherapies (up to 7.5 months). Biologics exhibited longer drug survival with fewer treatment episodes compared with non-biologic systemic medications. Among frequently used therapies, the median (95% confidence interval) drug survival was 8.8 (5.8-11.8) months for etretinate, 4.3 (2.2-6.9) months for systemic corticosteroids, and 19.6 (16.1-26.7) months for secukinumab. Treatment patterns varied considerably, highlighting the need for treatment algorithms and effective, well-tolerated medications to support patients to help them remain on long-term therapy.

Abstract
Generalized pustular psoriasis (GPP) is a rare, chronic, neutrophilic inflammatory skin disease characterized by episodes of widespread eruption of sterile, macroscopic pustules that can be accompanied by systemic inflammation and symptoms. A systematic literature review and narrative synthesis were conducted to determine the impact of GPP on patients' health-related quality of life (HRQoL) and patient-reported severity of symptoms and to compare its impact to patients with plaque psoriasis (plaque PsO). Searches were undertaken in Embase, MEDLINE and the Cochrane Library from 1 January 2002 to 15 September 2022. Screening was carried out by two reviewers independently. Outcome measures included generic (e.g. EQ-5D, SF-36) and dermatology-specific (e.g. DLQI) clinical outcome assessments, and other relevant patient-reported outcome measures (PROMs) (e.g. severity of pain measured by a numerical rating scale). Overall, 20 studies were found to be eligible for inclusion, of which seven also had data for plaque PsO. The DLQI was the most frequently reported outcome measure (16 out of 20 studies). When reported, mean DLQI (SD) scores varied from 5.7 (1.2) to 15.8 (9.6) across the studies, indicating a moderate to very large effect on HRQoL; the wide range of scores and large SDs were explained by the small population sizes (n ≤ 12 for all studies except two). Similar ranges and large SDs were also observed for other measures within individual studies. However, in general, people with GPP reported a greater impact of their skin condition on HRQoL, when compared to people with plaque PsO (i.e. higher DLQI scores) and higher severity for itch, pain and fatigue. This systematic review highlighted the need for studies with a larger population size, a better understanding of the impact of cutaneous and extracutaneous symptoms and comorbidities on HRQoL during and between GPP flares, and outcome measures specifically tailored to the unique symptoms and the natural course/history of GPP.

Abstract
BACKGROUND Generalized pustular psoriasis (GPP) is a rare, inflammatory skin disease characterized by widespread eruption of sterile pustules with or without systemic symptoms. OBJECTIVES This study aimed to describe the demographics of patients with GPP in Central and Eastern Europe (CEE), present the clinical characteristics of individual GPP flares and explore the current treatment landscape. METHODS Patient demographics were collected at the times of last observation and previous treatment. Characteristics of a patient's last (most recent) and most severe (from all documented episodes) flare were provided at clinician's discretion. RESULTS Fifty-eight patients were recruited from 12 centres in nine CEE countries; median (range) age was 61 (16-92) years and 60.3% (35 out of 58) were female. The most common comorbidities were hypertension (43.1% [25 out of 58]) and hyperlipidaemia (32.8% [19 out of 58]). Thirty-four patients (58.6%) presented with concomitant plaque psoriasis before or during the course of GPP. Data from two separate flares were recorded in 26 individuals; in 32 patients, the most recent flare was reported as the most severe. Over 90% of patients with a flare episode classified as most severe by clinicians were hospitalized, with >75% of these individuals having a Generalized Pustular Psoriasis Physician Global Assessment (GPPGA) total score of 3 or 4. Systemic symptoms were more common in patients with a GPPGA score of 3 or 4 but were also manifest in individuals with a GPPGA score ≤2. A significant correlation was observed between a combined systemic disease score of clinical and laboratory features and both GPPGA total score (r = 0.385, p < 0.001) and GPPGA pustulation subscore (r = 0.305, p < 0.05). CONCLUSIONS Considerable heterogeneity in the presentation of GPP flares was observed, both between patients and within-patient. All GPP flares were associated with a significant clinical burden, highlighting the unmet need for accurate and early diagnosis.

Abstract
INTRODUCTION In 2022, U.S. Food and Drug Administration (FDA) approved the first biologics, intravenous spesolimab, for acute flare of generalized pustular psoriasis (GPP). The drug works by blocking IL-36 signaling, the key pathway of GPP. Among the known mutations causing GPP, IL36RN mutations are most common, and the presence of IL36RN mutations had been found to affect the clinical manifestations and treatment response of GPP. AREAS COVERED Literature search was conducted in PubMed, Embase and ClinicalTrials.gov for relevant studies discussing biologic treatment for GPP with special emphasis on larger studies, pediatric group, pregnant women, and the influence of IL36RN mutation on the effectiveness of biologics. EXPERT OPINION The approval of spesolimab for GPP flare treatment marks a new era. However, whether spesolimab will be placed as the treatment of choice remains unknown, considering its higher cost, lack of direct comparison with existing biologics, and uncertain effects on co-existing plaque-type psoriasis. However, the demonstration of numerically better efficacy for patients carrying pathogenic IL36RN mutations suggests the role of pharmacogenetics in the choices of GPP treatment. Future randomized studies are warranted to investigate the effectiveness and safety of biologics for GPP in pediatric and pregnant groups.

Abstract
Background Generalised pustular psoriasis (GPP) is a chronic inflammatory skin disease. We aimed to visualize the research hotspots and trends of GPP using bibliometric analysis to enhance our comprehension of the future advancements in both basic science and clinical research. Methods Relevant publications from July 2003 to July 2023 were obtained from the Web of Science Core Collection on July 12, 2023. The analysis of countries, institutions, authors, references, and keywords associated with this subject was conducted through the utilisation of CiteSpace 6.2.R4, VOSviewer 1.6.18, and Microsoft Excel 2019. Results A total of 578 papers were analyzed, authored by 2758 researchers from 191 countries/regions and 1868 institutions, published in 174 academic journals. There was an overall upward trajectory in the volume of annual publications, accompanied by a gradual intensification of research interest in GPP. The United States, UDICE-French Research Universities, and Akiyama M of Nagoya University were the most productive and influential country, institution, and author, respectively. The Journal of Dermatology ranked first with the highest publications, and the Journal of the American Academy of Dermatology received the most citations. High-frequency keywords included "generalized pustular psoriasis", "psoriasis, interleukin-36", "plaque psoriasis", "skin-disease", and "antagonist deficiency". Recent research focuses have included "safety", "secukinumab", "spesolimab", "ap1s3 mutations", and "interleukin-36". Burst detection analysis of keywords showed that "moderate", "ixekizumab treatment", "mutations", "efficacy", and "safety" are current research frontiers in this field. Conclusion This bibliometric analysis delineated the landmark publications in GPP that have defined current research hotspots and development trends, notably the applications, efficacy, and safety of biological agents. Future research endeavors are warranted to explore other biological therapeutic options for both acute GPP and the long-term management of chronic GPP.

Abstract
INTRODUCTION Generalized pustular psoriasis (GPP) is a rare and potentially life-threatening skin disease. The global Effisayil 1 study investigated the efficacy and safety of spesolimab, a humanized monoclonal antibody targeting the IL-36 receptor, in patients experiencing GPP flare. This analysis aimed to explore the efficacy and safety of spesolimab in the Chinese subgroup of Effisayil 1. METHODS Effisayil 1 was a multicenter, randomized, double-blind, placebo-controlled phase II study. Eligible patients with a GPP flare were randomly assigned (2:1) to receive a single intravenous dose of spesolimab (900 mg) or placebo on day 1. On day 8, patients who had persistent symptoms that met a predefined criterion could receive open-label spesolimab. After day 8, patients with recurrent flares following clinical response could receive rescue treatment with open-label spesolimab. The primary end point was a Generalized Pustular Psoriasis Physician Global Assessment (GPPGA) pustulation sub-score of 0 at week 1. The key secondary end point was a GPPGA total score of 0 or 1 at week 1. RESULTS Eleven Chinese patients were randomized, with five patients receiving spesolimab and six receiving placebo. At week 1, 60.0% (3/5) of patients in the spesolimab group and 16.7% (1/6) of patients in the placebo group achieved a GPPGA pustulation sub-score of 0 (risk difference 43.3%; 95% CI -22.6, 86.2); 60.0% and 16.7% of patients in the spesolimab and placebo group, respectively, achieved a GPPGA total score 0 or 1 (risk difference 43.3%; 95% CI -22.6, 86.2). Overall, four patients in each group of the spesolimab and the placebo groups reported at least one adverse event (AE) by week 1, with two and three reporting drug-related AEs, respectively. One patient reported a serious AE that was not considered to be drug related. No death occurred during the study period. CONCLUSION In the Chinese subgroup of the Effisayil 1 study, more patients receiving spesolimab experienced lesion clearance than those on placebo at week 1, with an acceptable safety profile that was consistent with the global study population. TRIAL REGISTRATION NCT03782792.

Abstract
Generalized pustular psoriasis (GPP) is a rare, chronic, inflammatory skin disorder characterized by recurrent flares associated with skin erythema, desquamation, and widespread superficial sterile pustules, which may be severe ("lakes of pus"). Systemic symptoms are often present, including malaise, fever, and skin pain. In GPP, innate immune responses are driven by abnormal activation of the interleukin (IL)-36-chemokine-neutrophil axis and excessive neutrophil infiltration. This review highlights the IL-36 pathway in the context of the IL-1 superfamily and describes how unopposed IL-36 signaling can lead to the development of GPP. Targeted inhibition of the IL-36 receptor (IL-36R) is an attractive therapeutic strategy in the treatment of GPP, including flare prevention and sustained disease control. Spesolimab is a first-in-class, humanized, monoclonal antibody that binds specifically to the IL-36R and antagonizes IL-36 signaling. Spesolimab was approved by the US Food and Drug Administration in September 2022 to treat GPP flares in adults and was subsequently approved for GPP flare treatment in other countries across the world. Anti-IL-36R therapy, such as spesolimab, can mitigate flares and address flare prevention in GPP, presumably through rebalancing IL-36 signaling and modulating the pro-inflammatory response of the downstream effectors.

Abstract
Generalised pustular psoriasis (GPP) and acrodermatitis continua of Hallopeau (ACH) are two rare entities included in the spectrum of pustular psoriasis (PP). Due to the lack of randomised controlled clinical trials and standardized guidelines, their treatment remains a challenge for clinicians. Thus, herein we report our centre experience with the successful use of interleukin (IL)-17 inhibitors in three patients affected by PP. We also provide a brief overview of the current knowledge concerning the role of IL-17 in PP pathogenesis and of the use of IL-17 inhibitors in the treatment of PP. Based on our experience, anti-IL-17 molecules may represent a valuable therapeutical option for patients affected by different PP subtypes.

Abstract
Neutrophilic dermatoses (NDs) are a group of noninfectious disorders characterized by the presence of a sterile neutrophilic infiltrate without vasculitis histopathology. Their physiopathology is not fully understood. The association between neutrophilic dermatoses and autoinflammatory diseases has led some authors to propose that both are part of the same spectrum of diseases. The classification of NDs depends on clinical and histopathological features. This review focuses on the recent developments of treatments in these pathologies.

Abstract
Generalized pustular psoriasis (GPP) is a severe subtype of psoriasis, commonly combined with systemic inflammation. Gene mutations have been found to be associated with GPP and vary by ethnicity. Systemic treatments are usually required for the severity and potential complications of GPP. However, there is no common consensus in China, especially among pediatric patients, whose data are scarce. Acitretin, methotrexate, and cyclosporine are widely used in pediatrics with GPP, while the adverse effects should be highlighted. The emergence of different biological agents brings us into a new era. This article discusses the genetic background of Chinese patients and demonstrates the evidence of treatment in pediatrics with GPP.

Abstract
Pustular psoriasis is characterised by eruptions of neutrophilic sterile pustules. The European Rare and Severe Psoriasis Expert Network consensus defines pustular psoriasis into three subtypes; generalised pustular psoriasis (GPP), palmoplantar pustulosis and acrodermatitis continua of Hallopeau (ACH). Mixed forms are categorised according to their predominant features. However, the Japanese Dermatological Association includes ACH under the diagnosis of GPP. This article aims to review the similarities and differences between ACH and GPP. Based on our review, interleukin (IL)-36RN mutations, the most frequent genetic findings in pustular psoriasis are found most commonly in GPP, followed by ACH. Genotypes of IL-36RN mutations among GPP patients and ACH patients are different between European and Asian ethnicities. IL-36 signalling pathway is the main mechanism. Metabolic diseases are common comorbidities and joint involvement can occur in 20.5%-36.4% of both conditions. Associated plaque psoriasis is more common in GPP than in ACH. Generally, ACH, even the generalised type, does not have systemic inflammation whereas GPP can occur with or without systemic inflammation. ACH can occur before, simultaneously, or after the development of GPP. However, response to treatment for GPP and ACH even in the same patients appear to be different. ACH seemed to be more recalcitrant to treatment than GPP but severe flare of GPP can lead to morbidity and mortality. Although GPP and ACH share genotypes and pathogenesis, we believe that ACH should be classified separately from GPP, and not under diagnosis of GPP. Future research is warranted to satisfactorily distinguish the two conditions.

Abstract
Generalized pustular psoriasis (GPP) is a rare subset of psoriasis involving episodes of sterile pustules accompanied by inflammation and, often, systemic involvement. The inflammatory nature of GPP has potential for severe multisystem complications including high-output cardiac failure, infections, digestive system issues, and disfiguring or lethal acute flare episodes. The disease tends to have higher prevalence in females and Asians. The IL-1/IL-36 inflammatory pathway is a critical facet of GPP's pathology. Genetic mutations that are associated with GPP include modifications of Interleukin 36 Receptor Antagonist (IL36RN), Caspase Recruitment Domain Family Member 14 (CARD14), Adaptor Related Protein Complex 1 Subunit Sigma 3 (AP1S3), Myeloperoxidase (MPO) and Serpin Peptidase Inhibitor Clade A Member 3 (SERPINA3) genes. Treatment guidelines for GPP are not well-entrenched. Currently, only one GPP-specific treatment, the interleukin-36 receptor antagonist (IL-36Ra) spesolimab, has been approved for use in the United States. Additional anti-IL-36 pathway therapies are currently being developed. Other treatment options include other biologic therapies such as IL-17 inhibitors, IL-23 inhibitors and TNFα inhibitors. Non-biologic therapeutic options include retinoids, cyclosporine and methotrexate. Treatment options differ throughout the world; most countries utilize retinoids, cyclosporine and methotrexate as first-line non-biologic options. China and United Kingdom have no GPP-specific biologic therapies approved for use, while several biologic therapies are approved for use in Japan. This review aims to serve as an update on the current global management of GPP while also including relevant aspects of disease pathogenesis, diagnosis, clinical presentation, histopathology, aetiology and epidemiology.

Abstract
BACKGROUND Effisayil 1 was a randomized, placebo-controlled study of spesolimab, which is an anti-IL-36 receptor antibody, in patients presenting with a generalized pustular psoriasis flare. OBJECTIVE To assess the effects of spesolimab over the 12-week study. METHODS The primary endpoint of the study was Generalized Pustular Psoriasis Physician Global Assessment (GPPGA) pustulation subscore of 0 at week 1. Patients (N = 53) were randomized (2:1) to receive a single intravenous dose of 900 mg spesolimab or placebo on day 1. Patients could receive open-label spesolimab for persistent flare symptoms on day 8. RESULTS Most patients receiving spesolimab achieved a GPPGA pustulation subscore of 0 (60.0%) and GPPGA total score of 0 or 1 (60.0%) by week 12. In patients randomized to placebo who received open-label spesolimab on day 8, the proportion with GPPGA pustulation subscore of 0 increased from 5.6% at day 8 to 83.3% at week 2. No factors predictive of spesolimab response were identified in patient demographics or clinical characteristics. LIMITATIONS The effect of initial randomization was not determined conventionally beyond week 1 due to patients receiving open-label spesolimab. CONCLUSION Rapid control of generalized pustular psoriasis flare symptoms with spesolimab was sustained over 12 weeks, further supporting its potential use as a therapeutic option for patients.

Abstract
Generalized pustular psoriasis (GPP) is a severe and rare form of psoriasis, being a potentially life-threatening condition, characterized by recurring episodes or flares of widespread cutaneous erythema with macroscopic sterile pustules. An irregular innate immune response is linked to GPP, which is considered an auto-inflammatory disorder, while innate and adaptive immunopathogenic responses are involved in psoriasis pathogenesis. In consequence, different cytokine cascades have been suggested to be mainly involved in the pathogenesis of each different psoriasis form, with the interleukin (IL)23/IL17 axis implied in plaque psoriasis, and the IL36 pathway in the GPP. As regards GPP treatment, conventional systemic drugs available for plaque psoriasis are usually used as the first-line treatment option. However, contraindications and adverse events often limit the use of these therapies. In this scenario, biologic drugs may represent a promising treatment option. To date, even if 12 different biologics have been approved for plaque psoriasis, none of these is approved for GPP where they are employed off-label. Recently, spesolimab, an anti-IL36 receptor monoclonal antibody, has been recently approved for GPP. The purpose of this article is to assess the current literature about the use of biological therapies for the treatment of GPP to establish the basis for a shared GPP management algorithm.

Abstract
Psoriasis is a chronic inflammatory skin disease characterized by the appearance of clearly demarcated erythematous and scaly plaques. It can be divided into various types, including plaque, nail, guttate, inverse, and pustular psoriasis. Plaque psoriasis is the most commonly occurring type, though there is another rare but severe pustular autoinflammatory skin disease called generalized pustular psoriasis (GPP), which manifests with acute episodes of pustulation and systemic symptoms. Though the etiopathogenesis of psoriasis is not yet fully understood, a growing body of literature has demonstrated that both genetic and environmental factors play a role. The discovery of genetic mutations associated with GPP has shed light on our comprehension of the mechanisms of the disease, promoting the development of targeted therapies. This review will summarize genetic determinants as known and provide an update on the current and potential treatments for GPP. The pathogenesis and clinical presentation of the disease are also included for a comprehensive discussion.

Abstract
Background Erythrodermic psoriasis (EP) remains challenging to manage because it is rare and has complex complications. Although acitretin is recommended as an appropriate choice for EP, there is a lack of large-scale evidence. Objectives This study aims to assess the efficacy and safety of acitretin as systemic monotherapy in EP patients. Design We retrospectively analyzed data from patients with EP who received at least 3 months of acitretin as systemic monotherapy during hospitalization and out-patient follow-up from January 2005 to May 2021 at the Peking Union Medical College Hospital, China. Methods The efficacy was clinically evaluated after 1, 2, 4, and 12 weeks of treatment, which was classified as a good response (>75% of lesions cleared), partial response (50%-75% cleared), moderate response (25-50% cleared), or no response (<25% cleared). Safety was assessed on the basis of physical examination results and significant changes in laboratory examination results after 12 weeks of treatment. Results Overall, 81 patients (79.0% men; mean age, 47.9 years) were included. The acitretin dose ranged from 20 to 60 mg/day (0.3 to 0.8 mg/kg/day). The rates of good, partial, and moderate responses were 0.0%, 2.5%, and 42.0% at 1 week; 3.7%, 34.6%, and 61.7% at 2 weeks; 29.6%, 58.0%, and 12.4% at 4 weeks; and 85.2%, 13.6%, and 1.2% at 12 weeks after treatment initiation, respectively. EP patients transformed from psoriasis vulgaris showed a higher good/partial response rate compared with that of EP patients that developed from pustular or articular psoriasis (44.6% vs. 14.3%, p = 0.035). Patients with concurrent infection showed a lower rate of good/partial response compared with that of those without concurrent infection (16.7% vs. 44.4%, p = 0.049). Adverse effects were seen in 45 (55.6%) patients in 12 weeks, and dyslipidemia (n = 31; 38.3%), xerosis (n = 24; 29.6%), and elevated liver enzymes (n = 6; 7.4%) were most commonly reported. Twenty-three patients were followed up for over 3 years, and six (26.1%) patients had EP recurrence. Conclusions Acitretin as a systemic monotherapy showed satisfactory effectiveness for EP, especially in patients developed from psoriasis vulgaris and without infection.

Abstract
Brodalumab is a recombinant, fully human immunoglobulin IgG2 monoclonal antibody specifically targeted against interleukin-17RA that has been approved for the treatment of moderate-to-severe psoriasis in Europe. We developed a Delphi consensus document focused on brodalumab for the treatment of moderate-to-severe psoriasis. Based on published literature and their clinical experience a steering committee drafted 17 statements covering 7 domains specific to the treatment of moderate-to-severe psoriasis with brodalumab. A panel of 32 Italian dermatologists indicated their level of agreement using a 5-point Likert scale (from 1 = "strongly disagree" to 5 = "strongly agree") using an online modified Delphi method. After the first round of voting (32 participants), positive consensus was reached for 15/17 (88.2%) of the proposed statements. Following a face-to-face virtual meeting, the steering committee decided that 5 statements would form "main principles" and 10 statements formed the final list. After a second round of voting, consensus was reached in 4/5 (80%) of the main principles and 8/10 (80%) for consensus statements. The final list of 5 main principles and 10 consensus statements identify key indications specific to the use of brodalumab in the treatment of moderate-to-severe psoriasis in Italy.

Abstract
BACKGROUND Generalized pustular psoriasis (GPP) is a rare inflammatory skin disease with a considerable clinical burden. In the Effisayil™ 1 study, spesolimab, an anti-interleukin-36 receptor monoclonal antibody, demonstrated efficacy in treating GPP flares. OBJECTIVES To evaluate patient-reported outcomes (PROs) of patients with GPP who were treated with intravenous (IV) spesolimab 900 mg in the Effisayil™ 1 study. METHODS Fifty-three patients presenting with a GPP flare were randomized (2:1) to receive a single dose of IV spesolimab 900 mg or placebo and were followed for 12 weeks. Four PROs (pain visual analogue scale [pain VAS]; Functional Assessment of Chronic Illness Therapy-Fatigue [FACIT-Fatigue]; Dermatology Life Quality Index [DLQI]; and Psoriasis Symptom Scale [PSS]) were assessed throughout the 12-week study. Minimal clinically important differences (MCIDs) were defined. All data are reported descriptively. RESULTS In patients who received spesolimab, improvements from baseline (median [Q1, Q3]) were observed in pain VAS (-21.3 [-55.3, -3.1]), FACIT-Fatigue (7.0 [1.0, 20.0]), DLQI (-2.5 [-8.0, 1.0]) and PSS (-4.0 [-7.0, 0.0]) within 1 week of treatment. These improvements were sustained over 12 weeks and corresponded to the achievement of MCIDs at Week 1, which were also sustained over 12 weeks. Patients in the placebo arm experienced improvements in PROs and achievement of MCIDs after receipt of open-label spesolimab at Week 1. CONCLUSIONS Patients with a GPP flare treated with spesolimab achieved improvements in PROs by Week 1, which were sustained for 12 weeks, and achieved MCIDs as early as Week 1.

Abstract
BACKGROUND Generalized pustular psoriasis (GPP) is a rare and highly heterogeneous skin disease, characterized by flares of neutrophilic pustules and erythema. As a rare disease with few clinical studies and no standardized management approaches, there is a paucity of knowledge regarding GPP. OBJECTIVES Conduct a Delphi panel study to identify current evidence and gain advanced insights into GPP. METHODS A systematic literature review was used to identify published literature and develop statements categorized into four key domains: clinical course and flare definition; diagnosis; treatment goals; and holistic management. Statements were rated on a Likert scale by a panel of dermatologists in two rounds of online questionnaires; the threshold for consensus was agreement by ≥80%. RESULTS Twenty-one panellists reached consensus on 70.9%, 61.8%, 100.0% and 81.8% of statements in the 'clinical course and flare definition', 'diagnosis', 'treatment goals' and 'holistic management of GPP' domains, respectively. There was clear consensus on GPP being phenotypically, genetically and immunologically distinct from plaque psoriasis. Clinical course is highly variable, with an extensive range of complications. Clinical and histologic features supporting GPP diagnosis reached high levels of agreement, and although laboratory evaluations were considered helpful for diagnosis and monitoring disease severity, there was uncertainty around the value of individual tests. All acute and long-term treatment goals reached consensus, including rapid and sustained clearance of pustules, erythema, scaling and crust, clearance of skin lesions and prevention of new flares. Potential triggers, associated comorbidities and differential diagnoses achieved low rates of consensus, indicating that further evidence is needed. CONCLUSIONS Global consensus between dermatologists was reached on clinically meaningful goals for GPP treatment, on key features of GPP flares and on approaches for assessing disease severity and multidisciplinary management of patients. On this basis, we present a management algorithm for patients with GPP for use in clinical practice.

Abstract
Background: Generalized pustular psoriasis (GPP) is a rare, severe inflammatory skin disease characterized by recurrent episodes of flares. Characteristics of patients experiencing a flare are hardly described in a real-life setting. The aim of the study is to investigate the clinical characteristics of patients experiencing a flare of GPP. Methods: Multicenter retrospective observational study on consecutive patients experiencing a flare of GPP between 2018 and 2022. Disease severity and quality of life were assessed by Generalized Pustular Psoriasis Area, Body Surface Area (BSA), and Severity Index (GPPASI), and Dermatology life quality index (DLQI) questionnaire, respectively. Visual analogue scale (VAS) of itch and pain, triggers, complications, comorbidities, pharmacological therapies, and outcome were collected. Results: A total of 66 patients, 45 (68.2%) females, mean age 58.1 ± 14.9 years, were included. The GPPASI, BSA, and DLQI were 22.9 ± 13.5 (mean ± standard deviation), 47.9 ± 29.1, and 21.0 ± 5.0, respectively. The VAS of itch and pain were 6.2 ± 3.3 and 6.2 ± 3.0, respectively. Fever (>38 °C) and leukocytosis (WBC > 12 × 109/L) were found in 26 (39.4%) and 39 (59.1%) patients, respectively. Precipitating triggers were identified in 24 (36.3%) and included infections (15.9%), drugs (10.6%), stressful life events (7.6%), and corticosteroids withdrawal (3.0%). Fourteen (21.2%) patients were hospitalized because of complications including infections in 9 (13.6%) leading to death in one case and hepatitis in 3 (4.5%). Conclusions: GPP flares can be severe and cause severe pain and itch with significant impact on the quality of life. In about one-third of patients the flare may have a persistent course and, with complications, lead to hospitalization.

Abstract
BACKGROUND Generalized pustular psoriasis (GPP) is a rare and life-threatening skin disease often accompanied by systemic inflammation. There are currently no standardized or validated GPP-specific measures for assessing severity. OBJECTIVE To evaluate the reliability, validity and responder definitions of the Generalized Pustular Psoriasis Physician Global Assessment (GPPGA) and Generalized Pustular Psoriasis Area and Severity Index (GPPASI). METHODS The GPPGA and GPPASI were validated using outcome data from Week 1 of the Effisayil™ 1 study. The psychometric analyses performed included confirmatory factor analysis, item-to-item/item-to-total correlations, internal consistency reliability, test-retest reliability, convergent validity, known-groups validity, responsiveness analysis and responder definition analysis. RESULTS Using data from this patient cohort (N = 53), confirmatory factor analysis demonstrated unidimensionality of the GPPGA total score (root mean square error of approximation <0.08), and GPPGA item-to-item and item-to-total correlations ranged from 0.58 to 0.90. The GPPGA total score, pustulation subscore and GPPASI total score all demonstrated good test-retest reliability (intraclass correlation coefficient: 0.70, 0.91 and 0.95 respectively), and good evidence of convergent validity. In anchor-based analyses, all three scores were able to detect changes in symptom and disease severity over time; reductions of -1.4, -2.2 and - 12.0 were suggested as clinically meaningful improvement thresholds for the GPPGA total score, GPPGA pustulation subscore and GPPASI total score respectively. Anchor-based analyses also supported the GPPASI 50 as a clinically meaningful threshold for improvement. CONCLUSIONS Overall, our findings indicate that the GPPGA and GPPASI are valid, reliable and responsive measures for the assessment of GPP disease severity, and support their use in informing clinical endpoints in trials in GPP.

Abstract
Generalized pustular psoriasis is a potentially life-threatening neutrophilic skin disease characterized by recurrent flares of widespread erythema and eruption of sterile pustules. In the Effisayil™ 1 study (NCT03782792), 53 patients with a generalized pustular psoriasis flare were treated with placebo or spesolimab, a humanized anti-interleukin-36 receptor monoclonal antibody, the first targeted treatment to be studied in a randomized clinical trial. Spesolimab treatment resulted in rapid pustular and skin clearance, with an acceptable safety profile. Here, we evaluate the efficacy and safety of spesolimab in 29 Asian patients in the Effisayil™ 1 study. The primary endpoint, a Generalized Pustular Psoriasis Physician Global Assessment (GPPGA) pustulation subscore of 0 (no visible pustules) at Week 1, was achieved by 10 patients (62.5%) randomized to spesolimab and one patient (7.7%) randomized to placebo (risk difference 54.8, 95% confidence interval [CI] 17.3-79.8). The key secondary endpoint, a GPPGA total score of 0 or 1 (clear or almost clear skin) at Week 1, was achieved by eight (50.0%) and two (15.4%) patients, respectively (risk difference 34.6, 95% CI -3.1-64.7). This was similar to previously published data in the overall population in whom the primary and key secondary endpoints were achieved by 54% versus 6% and 43% versus 11% of patients, respectively. The percentages of Asian patients randomized to spesolimab with a GPPGA pustulation subscore of 0 and GPPGA total score of 0 or 1 were sustained above 60% for up to 12 weeks. In these patients, patient-reported outcomes also improved and markers of systemic inflammation were normalized. Eleven (68.8%) and eight (61.5%) of spesolimab- and placebo-treated patients, respectively, experienced at least one adverse event. In conclusion, spesolimab improved outcomes in Asian patients compared with placebo, supporting its use in the treatment of generalized pustular psoriasis flares.

Abstract
This is the English version of Japanese guidance for use of biologics for psoriasis (the 2022 version). As the first biologics for psoriasis in Japan, infliximab and adalimumab, anti-tumor necrosis factor-α antibodies, became available in the field of dermatology in 2010, followed by ustekinumab, an anti-interleukin (IL)-12/IL-23p40 antibody, which was launched in Japan in 2011. Moreover, after 2015, three IL-17 inhibitors, the IL-17A antibody preparations secukinumab and ixekizumab, and an anti-IL-17 receptor antibody preparation brodalumab were marketed. Furthermore, after 2018, the anti-IL23p19 antibody preparations guselkumab and risankizumab, the TNF inhibitor certolizumab pegol, the IL-23 inhibitor tildrakizumab, and the anti-IL-17A/F antibody bimekizumab were marketed. It is important for physicians to select appropriate biologic therapy for each psoriatic patient after due consideration of disease factors, treatment factors, and patient background factors, sharing such information with patients. The followings can be listed as points to be considered for the selection of biologics: drug effects (e.g., strength of effectiveness, time to onset of effectiveness, effectiveness against arthritis, primary failure, secondary failure), safety (e.g., infections, administration-related reactions, and relationships with other comorbidities), convenience for patients (e.g., hospital visit intervals, self-injection, maintenance therapy at clinics, feasibility of drug discontinuation/re-administration), and payment (medical costs) borne by patients. This guidance has been prepared with the aim of allowing dermatologists experienced in the treatment of psoriasis to use biologics appropriately according to the circumstances of individual patients after consideration of the above-mentioned factors.

Generalized pustular psoriasis (GPP) is a rare auto-inflammatory skin disease characterised by acute episodes of sterile pustule formation. Diagnosis and treatment of the disease have historically been complicated by a lack of awareness, and no consistent global definition or clinical coding standards. Now acknowledged as a distinct clinical entity with a recognised genetic component, GPP can take a serious and life-threatening course due to systemic inflammatory complications and its association with various comorbidities. As with other rare diseases, there are significant challenges to understanding the epidemiology of GPP, notably a small patient population, non-standardised study methodologies and ethnic differences in its presentation. A clearer understanding of GPP is therefore required for clinicians to better manage patients with this rare condition. In this review article, we present an overview of the available data on GPP prevalence estimates in key demographics and report the frequency of genetic mutations associated with the disease. We detail the incidence of known comorbidities and summarise the data on mortality and assigned causes of death. Lastly, we discuss the various factors that impact the collection, interpretation and comparison of these data.

Abstract
INTRODUCTION Pustular psoriasis (PP) is a rare subtype of psoriasis. Overall, the growing evidence - in particular for acute generalized PP (GPP) - supports that it is a separate entity with a specific pathogenetic pathway. Interleukin (IL)-17/T-helper 17 (Th17) axis involvement may play an important role in the pathophysiology of PP. Biologicals, often required to achieve clinical remission, have changed the treatment of PP. AREAS COVERED We provide the reader with an overview of all the available evidence on the use of the antibody-based therapy targeting IL-17A in patients with PP. EXPERT OPINION Although papers reported in this review do not provide definitive evidence (due to methodological limitations) to support the use of IL-17 inhibitors as potential first-line for the treatment of PP, based on our own experience and according to most of the reported literature, targeting IL-17A, may represent the best therapeutical approach in this peculiar clinical spectrum of psoriasis.

Abstract
INTRODUCTION Erythrodermic psoriasis (EP) is an extreme and potentially life-threatening form of psoriasis in which most or all of the body surface area is affected by psoriasis. It occurs in 1-2% of patients with psoriasis and is less responsive to conventional therapies. Biologics have shown promise in the management of EP. AREAS COVERED This review briefly discusses the pathophysiology of EP. Current evidence on established and emerging targeted therapies for EP is covered, including anti-TNF-α biologics, IL-12/23, IL-17, and IL-23 inhibitors. EXPERT OPINION The need for rapidly acting, safe, and efficacious agents in EP has been met with advent of newer biologics, particularly IL-17 and IL-23 inhibitors. These targeted approaches warrant consideration as first-line management option for the management of EP; however, high-quality evidence regarding their long-term efficacy and safety in EP is lacking. Novel biologics such as bimekizumab and mirikizumab, and nanobodies such as netakimab and sonelokimab have shown promise in the management of plaque psoriasis, and potential of these molecules in management of EP should be explored. Management of patients with prior biologic failure remains a challenge. Guidelines for the management of EP need to be revisited in light of the recent advances.

Abstract
Generalized pustular psoriasis (GPP) is a rare and potentially life-threatening autoinflammatory skin disease, mainly mediated by the interleukin (IL)-36 signaling pathway. The irregular and relapsing pattern of the skin symptoms, the GPP-associated complications, as well as the physical pain caused by the disease add burdens to patients with GPP. Currently, spesolimab, a humanized monoclonal antibody targeting the IL-36 receptor, has been approved as a GPP-specific treatment targeting IL-36 signaling. Effisayil 1, a randomized, controlled clinical trial, investigated the efficacy and safety of spesolimab in patients presenting with a GPP flare. In this commentary, we discuss the study design, endpoints, and clinical outcomes of Effisayil 1, which differed from previous clinical trials that investigated other biologic agents (adalimumab, secukinumab, brodalumab, ixekizumab, and guselkumab) in patients with GPP.

Abstract
INTRODUCTION Generalized pustular psoriasis (GPP) is a rare, severe, clinically heterogeneous disease characterized by flares of widespread, non-infectious, macroscopically visible pustules that occur with or without systemic inflammation, and are associated with significant morbidity and mortality. Historically, GPP has been classified as a variant of psoriasis vulgaris (PV, or plaque psoriasis); however, accumulating evidence indicates that these are distinct conditions, requiring different treatment approaches. AREAS COVERED In this perspectives article we review evidence that supports the classification of GPP as distinct from PV. EXPERT OPINION The histopathologic and clinical appearance of GPP is distinct from that of PV and fundamental differences exist between the two conditions in terms of genetic causes and expression-related mechanisms of disease development. GPP results from dysregulation of the innate immune system, with disruption of the interleukin (IL)-36 inflammatory pathway, induction of inflammatory keratinocyte responses, and recruitment of neutrophils. PV is driven by the adaptive immune system, with a key role played by IL-17. Considering GPP as a separate disease will enable greater focus on its specific pathogenesis and the needs of patients. Many treatments for PV have insufficient efficacy in GPP and a therapeutic approach developed specifically for GPP might lead to better patient outcomes.

Abstract
INTRODUCTION Generalized pustular psoriasis (GPP) is a rare, severe, immune-mediated and potentially life-threatening skin disease. The rarity, differential diagnoses, relapsing nature, skin and systemic symptoms, complications and limited therapeutic approaches for this disease pose a clinical and psychological burden on patients and their families. AREAS COVERED Epidemiologic data of GPP in Chinese patients, including the disease prevalence and age of disease onset, as well as epidemiologic data in global populations were reviewed. Multiple proinflammatory cytokines are involved in the disease development and clinical presentation of GPP and the interleukin (IL)-36-mediated signalling pathway play a central role. Furthermore, loss-of-function mutations in IL-36RN (encoding the IL-36 receptor antagonist) are associated with GPP, suggesting a potential drug target for developing a disease-specific therapeutic approach. Biologic agents, including IL-36R targeted agents, are promising treatment options, especially as existing conventional therapies are inadequate. Chinese guidelines for the diagnosis and treatment of psoriasis recommend systemic and topical treatment options for GPP and disease complications, as well as for GPP during pregnancy and juvenile GPP. EXPERT OPINION This review summarizes the epidemiology, pathogenesis, clinical characteristics, disease burden and management of patients with GPP in China, and also describes future treatment targets and related clinical trials.

Abstract
Biologics may elicit the production of anti-drug antibodies (ADAs), the clinical significance of which is not fully understood. ADA development in psoriasis patients on IL-17 inhibitors was evaluated by incidence, impact on efficacy, and relationship with adverse events. We systematically searched PubMed, Cochrane, and Embase databases, identifying 456 references. 17 studies met inclusion criteria. ADA incidence was: 0% to 5.5% (secukinumab), 11% to 19.4% (ixekizumab), 0% to 3.3% (brodalumab), and 19% to 39% (bimekizumab). Neutralizing antibody incidence was: 0% to 1.5% (secukinumab), 0% to 3.5% (ixekizumab), and 0% (brodalumab). ADA presence alone with secukinumab, ixekizumab, and bimekizumab did not impact drug efficacy. Brodalumab was the only one of the IL-17 inhibitors, which showed a reduction in efficacy in ADA + patients. In one analysis, high ADA titers to ixekizumab were associated with diminished treatment response. ADAs to secukinumab and bimekizumab were not associated with adverse events. There were limited data on ADAs and safety with ixekizumab or brodalumab. Overall, when monitoring patients on secukinumab, ADAs, titers, and the presence of neutralizing antibodies were not prognostic of outcomes. However, monitoring for ADAs with brodalumab and measuring titers with ixekizumab may be of value clinically.

Abstract
PURPOSE OF REVIEW Psoriasis vulgaris is the commonest presentation of psoriatic disease, but morphologic variants such as pustular psoriasis (PP) and a closely related disease, pityriasis rubra pilaris (PRP), have been known for a long time, have been associated with rheumatologic manifestations indistinguishable from psoriatic arthritis (PsA) that may go unrecognized, and often represent a therapeutic conundrum. There is recent evidence that underlying genetic and pathogenetic differences may provide the basis for newer therapeutic approaches. RECENT FINDINGS This narrative review highlights the clinical, genetic and pathogenetic characteristics of PP and PRP, their association with PsA and recent developments in their treatment, especially with biologic agents targeting IL-36 and other cytokines of pathogenic relevance. SUMMARY The clinical manifestations of PP and PRP are less well known to rheumatologists than those of psoriasis, and recent advances in our insight on their pathogenesis may eventually overcome the therapeutic difficulties faced by dermatologists and rheumatologists in the management of these diseases and their rheumatologic manifestations.

Abstract
Anti-interleukin (IL)-17 agents have shown excellent therapeutic efficacy in patients with psoriasis and are expected to be expanded to other chronic inflammatory diseases. However, patients receiving anti-IL-17 agents are at an increased risk of developing Candida infection, with some agents reported to increase the incidence in a dose-dependent manner. Interleukin-17 is secreted by the Th17 subset of CD4+ lymphocytes, CD8+ T cells, and innate cells, including natural killer T cells, lymphoid tissue inducer cells, innate lymphoid cells, and γδ-T cells, and plays an important role in antifungal defense. Genetic defects in the IL-17-signaling pathway in both humans and animal models render susceptibility to candidiasis caused by Candida albicans. The purpose of this narrative review is to evaluate the literature on the role of IL-17 in protection against candidiasis, the prevalence of candidiasis in anti-IL-17 agent use, and to offer clinical recommendations on the diagnosis and management of anti-IL-17 medication-associated candidiasis.

Abstract
Generalized pustular psoriasis (GPP) is a rare, severe neutrophilic skin disease characterized by sudden widespread eruption of sterile pustules with or without systemic symptoms. GPP may be life threatening in cases with severe complications such as cardiovascular failure, acute respiratory distress syndrome, and serious infections. Impetigo herpetiformis (IH) is a GPP that is induced and exacerbated by pregnancy and occurs most frequently during the last trimester. IH may result in poor or fatal neonatal outcomes, including placental insufficiency, fetal abnormalities, stillbirth, and early neonatal death. Most patients have prompt remission in the postpartum period; however, earlier appearance and more severe symptoms are observed during subsequent pregnancies. Appropriate treatment and close monitoring of the mother and fetus are vital for the management of patients with IH. Particular attention is required for the management of patients with IH to avoid an influence on the fetus. However, data regarding treatments for GPP in pregnant women are sparse. Over the last decade, many patients with IH have been treated with cyclosporine, corticosteroids, tumor necrosis factor-α inhibitors, interleukin (IL)-17 and IL-12/23 inhibitors, and granulocyte and monocyte adsorption apheresis (GMA). GMA may be an important option for patients with IH as it is presently one of the safest available therapeutic options, but there have been no reports to fully confirm its safety in pregnant patients with GPP. Alternatively, based on recent advances in the understanding of the role of the IL-36 axis in the pathogenesis of GPP, biologic agents that target the IL-36 pathway may demonstrate promising efficacy in IH.

Abstract
Generalized pustular psoriasis (GPP) is a rare, severe, potentially life-threatening, autoinflammatory, neutrophilic skin disease that may be accompanied by fever and leukocytosis. This paper describes the current state of knowledge on GPP in terms of classification, (differential) diagnosis and prevalence. We present a comparison of the genetics and pathoimmunology of GPP and psoriasis vulgaris with the central mechanisms of autoimmunology and autoinflammation. The currently available therapeutic options, expert recommendations for therapy, and data from early clinical trials investigating targeted therapies will be summarized. We present the results of our discussion with 13 experts for psoriasis vulgaris and GPP and give an integrated overview of indication and therapy based on our personal experience and present an outlook on further research questions. Collectively, this article highlights the high unmet need in GPP, as there exists no satisfactory method of diagnosis or treatment to date and new treatment options will be of great therapeutic benefit to those affected.

Abstract
Introduction We report an exploratory analysis of the efficacy and safety of certolizumab pegol (CZP) in Japanese patients with generalized pustular psoriasis (GPP) and erythrodermic psoriasis (EP) (NCT03051217). Methods Patients ≥ 20 years with GPP or EP were randomized 1:1 to open-label CZP 400 mg every 2 weeks (Q2W) or 200 mg Q2W (400 mg weeks 0/2/4) for 16 weeks; patients who achieved “much improved” or “very much improved” on the Global Improvement Score (GIS; for GPP) or a PASI 50 response (≥ 50% reduction from baseline Psoriasis Area and Severity Index; for EP) continued to week 52. Efficacy outcomes assessed included Clinical Global Impression of Improvement (CGI-I), Dermatology Life Quality Index (DLQI 0/1), and Itch Numeric Rating Scale (INRS 0). GIS and Japanese Dermatological Association (JDA) severity index were assessed in patients with GPP, and PASI and Physician’s Global Assessment (PGA) in patients with EP. Treatment-emergent adverse events (TEAEs) were evaluated through weeks 0–52. Results Of 22 patients randomized, 19 completed week 52. At week 16, all reported outcomes improved with both CZP doses and were generally maintained through week 52. At week 52, 6/7 GPP and 12/12 EP patients achieved CGI-I response (“improved” or “remission”). Also, 4/7 GPP and 7/12 EP patients achieved DLQI 0/1; 2/7 GPP and 2/12 EP patients achieved INRS 0. Meanwhile, 6/7 patients with GPP achieved GIS response, and JDA severity index was reduced from baseline. We found that 9/12 and 5/12 patients with EP achieved PASI 90 and PGA 0/1, respectively. Overall, three serious TEAEs were reported in three CZP 400 mg Q2W-treated patients. Conclusion CZP treatment over 16 weeks improved the signs and symptoms of GPP and EP, and improvements were maintained through week 52. No new safety signals were identified.

Abstract
Mutations in genes such as transglutaminase-1 (TGM1), which are responsible for the formation and normal functioning of a lipid barrier, lead to the development of autosomal recessive congenital ichthyosis (ARCI). ARCIs are characterized by varying degrees of hyperkeratosis and the presence of scales on the body surface since birth. The quality of life of patients is often significantly affected, and in order to alleviate the manifestations of the disease, symptomatic therapy with moisturizers, keratolytics, retinoids and other cosmetic substances is often used to improve the condition of the patients' skin. Graft transplantation is commonly used to correct defects of the eye. However, these approaches offer symptomatic treatment that does not restore the lost protein function or provide a long-term skin barrier. Gene and cell therapies are evolving as promising therapy for ARCIs that can correct the functional activity of altered proteins. However, these approaches are still at an early stage of development. This review discusses current studies of gene and cell therapy approaches for various types of ichthyosis and their further prospects for patient treatment.

Abstract
Generalized pustular psoriasis (GPP) is a rare, severe neutrophilic skin disorder characterized by sudden widespread eruption of superficial sterile pustules with or without systemic inflammation. GPP flares can be life-threatening if untreated due to potential severe complications such as cardiovascular failure and serious infections. Currently, there are no GPP-specific therapies approved in the USA or Europe. Retinoids, cyclosporine, and methotrexate are the most commonly used non-biologic therapies for GPP. The evidence that supports the currently available treatment options is mainly based on case reports and small, open-label, single-arm studies. However, recent advances in our understanding of the pathogenic mechanisms of GPP and the identification of gene mutations linked to the disease have paved the way for the development of specific targeted therapies that selectively suppress the autoinflammatory and autoimmune mechanisms induced during GPP flares. Several biologic agents that target key cytokines involved in the activation of inflammatory pathways, such as tumor necrosis factor-α blockers and interleukin (IL)-17, IL-23, and IL-12 inhibitors, have emerged as potential treatments for GPP, with several being approved in Japan. The evidence supporting the efficacy of these agents is mainly derived from small, uncontrolled trials. A notable recent advance is the discovery of IL36RN mutations and the central role of IL-36 receptor ligands in the pathogenesis of GPP, which has defined key therapeutic targets for the disease. Biologic agents that target the IL-36 pathway have demonstrated promising efficacy in patients with GPP, marking the beginning of a new era of targeted therapy for GPP.

Abstract
Generalized pustular psoriasis (GPP) is a rare neutrophilic skin condition characterized by episodes of widespread eruption of sterile macroscopic pustules that can be associated with systemic inflammation. The rarity of GPP and its heterogeneous cutaneous and extracutaneous symptoms pose considerable challenges to the development and adoption of comprehensive accurate disease measures for the routine clinical assessment of disease severity and the evaluation of new treatments in clinical trials. Psoriasis disease measures remain among the most commonly used methods for evaluating patients with GPP, despite their limitations owing to a lack of assessment of pustules (a hallmark of GPP), systemic inflammation, and disease symptoms. The adaptation of psoriasis disease measures and the development of assessment tools specific for GPP severity will enable more effective and accurate monitoring of patients with GPP and enhance the clinical development of new therapies. Further clinical validation of recently developed modified assessment tools, such as the Generalized Pustular Psoriasis Physician Global Assessment and the Generalized Pustular Psoriasis Area and Severity Index, and international consensus on using quantitative tools and patient-reported outcome measures in the development of new treatments are needed to advance patient care.

Abstract
Generalized pustular psoriasis (GPP) is a rare, severe form of pustular psoriasis characterized by widespread, recurrent episodes of neutrophil-rich pustule formation in the epidermis, which can be accompanied by fever and systemic inflammation. Recent clinical, histologic, and genetic evidence indicates that GPP is a distinct entity from plaque psoriasis, with different cytokine pathways predominant in the manifestation of each disease. The interleukin-36 (IL-36) signaling cascade plays a key role in regulating the innate immune system, and its dysregulation appears central to the pathogenesis of GPP. The altered expression of various IL-36 pathway constituents has been shown to cause a positive feedback loop of uncontrolled signaling and excess production of inflammatory cytokines, which in turn leads to chemokine induction and neutrophil recruitment in the epidermis. Given the potentially life-threatening nature of GPP episodes, drug interventions that rapidly achieve disease resolution are required. Early phase data indicate that treatments targeting various components of the IL-36 inflammatory cascade represent promising areas of research. However, there are currently no therapeutic agents specifically approved for GPP in the USA or Europe. Understanding the inflammatory pathways, associated risk factors, and role of neutrophils in the manifestation and perpetuation of GPP flares remains a key goal in developing effective therapeutics. In this article, we summarize the current understanding of GPP, describe novel therapeutic opportunities, and detail how the unique pathophysiology of the disease may inform future treatment strategies.

Abstract
Generalized pustular psoriasis (GPP) is a severe psoriatic subtype characterized by epidermal neutrophil infiltration. Although variants in IL36RN and MPO have been shown to affect immune cells, a systematic analysis of neutrophils and peripheral blood mononuclear cells (PBMCs) subsets and their differential gene expression dependent on MPO genotypes was not performed yet. We assessed transcriptomes of MPO-deficient patients using single cell RNA-sequencing (scRNAseq) of PBMCs and RNA-sequencing of neutrophils in stable disease state. Cell type annotation by multimodal reference mapping of scRNAseq data was verified by flow cytometry of surface and intracellular markers; proportions of CD4+ cytotoxic T-lymphocytes (CTLs) and other CD4+ effector cells were increased in GPP, while frequencies of naïve CD4+ T cells were significantly lower. The expression of FGFBP2 marking CD4+ CTLs and CD8+ effector memory T-cells (TEMs) was elevated in GPP patients with disease-contributing variants compared to non-carriers (p=0.0015). In neutrophils, differentially expressed genes (DEGs) were significantly enriched in genes of the classical complement activation pathway. Future studies assessing affected cell-types and pathways will show their contribution to GPP's pathogenesis, and indicate whether findings can be transferred to the acute epidermal situation and whether depletion or inactivation of CD4+ CTLs may be a reasonable therapeutic approach.

Abstract
INTRODUCTION In 2018, ixekizumab (80 mg every 2 weeks [Q2W] beyond Week 12) received approval in Japan for patients with generalized pustular psoriasis (GPP) and erythrodermic psoriasis (EP). This open-label study evaluated the efficacy and safety of ixekizumab (80 mg Q2W from Week 12 to Week 20) in Japanese patients with GPP and EP. METHODS Seven patients with GPP and five patients with EP were enrolled. An initial dose of 160 mg (subcutaneous [SC] injection) was followed by 80 mg Q2W SC until Week 12. Primary endpoint assessed global improvement score (GIS) by comparing psoriatic findings, Static Physician Global Assessment, Psoriasis Area and Severity Index score, and other evaluations with those at the baseline and were graded as 1 = resolved, 2= improved, 3 = unchanged, and 4 = worsened. Patients who showed GIS = 1 (resolved) at Week 12 completed the study. Patients with GIS ≥ 2 continued to receive ixekizumab 80 mg Q2W until Week 20. RESULTS At Week 12, four of seven patients with GPP showed "resolved," two showed "improved," and one showed "worsened." Of five patients with EP, one showed "resolved" and four showed "improved." Two patients with GPP and four patients with EP continued ixekizumab treatment until Week 20. At Week 20, one of the two patients with GPP showed "resolved" and one patient showed "improved." All four patients with EP showed "improved." One non-drug related serious adverse event was reported by one patient with EP at Week 12. From Week 12 to Week 20, no adverse events (AEs) were reported in patients with GPP, but two mild AEs were reported in one of the four patients with EP. CONCLUSIONS This study indicates that ixekizumab continuous Q2W dosing is efficacious and safe for patients with GPP and EP. CLINICAL TRIAL REGISTRATION NCT03942042.

Abstract
An intact and fully functional immune system plays a crucial role in the prevention of several infectious diseases. Interleukin (IL)17 is significantly involved in oral mucosa immunity against several antigens and microorganisms, including Candida albicans (CA). Herein, we present three cases of oral candidiasis (OC) related to the use of an IL17A inhibitor for psoriasis. Three psoriatic individuals presented for evaluation of widespread symptomatic oral lesions temporally correlated with the onset of IL17A inhibitors (secukinumab in two patients and brodalumab in one patient). Clinical examination revealed either partially removable white plaques in an erythematous background (case #1) or diffuse erythematous lesions (cases #2 and 3) involving several areas of the oral mucosa. Cytology smear, accompanied by histopathologic examination in case #1, confirmed the clinical impression of OC in all three cases. All patients received antifungal therapy with satisfactory clinical response. No discontinuation of the antipsoriatic regimen was recommended, but all patients were advised to remain under monitoring for possible OC relapses. During the last few years, new systemic biologic agents targeting IL17 have been used for the management of variable immune-mediated diseases. Few clinical trials and scarce case reports have shown that these medications place individuals at high risk of developing candidiasis. We propose that patients treated with these medications should be at close monitoring for the development of OC and, if it occurs, receive appropriate management.

Abstract
Pustular psoriasis (PP) is a clinicopathological entity encompassing different variants, i.e., acute generalized PP (GPP), PP of pregnancy (impetigo herpetiformis), annular (and circinate) PP, infantile/juvenile PP, palmoplantar PP/palmoplantar pustulosis, and acrodermatitis continua of Hallopeau (ACH), which have in common an eruption of superficial sterile pustules on an erythematous base. Unlike psoriasis vulgaris, in which a key role is played by the adaptive immune system and interleukin (IL)-17/IL-23 axis, PP seems to be characterized by an intense inflammatory response resulting from innate immunity hyperactivation, with prominent involvement of the IL-36 axis. Some nosological aspects of PP are still controversial and debated. Moreover, owing to the rarity and heterogeneity of PP forms, data on prognosis and therapeutic management are limited. Recent progresses in the identification of genetic mutations and immunological mechanisms have promoted a better understanding of PP pathogenesis and might have important consequences on diagnostic refinement and treatment. In this narrative review, current findings in the pathogenesis, classification, clinical features, and therapeutic management of PP are briefly discussed.

Abstract
Pustular psoriasis is an unusual form of psoriasis that frequently presents clinical challenges for dermatologists. The condition presents with pustules on an erythematous background and has two distinct subtypes: localized disease on the palms and soles, called palmoplantar pustulosis (PPP), and generalized pustular psoriasis (GPP). The involvement of the fingers, toes, and nails is defined as a separate localized variant, acrodermatitis continua of Hallopeau, and is now thought to be a subset of PPP. The rarity of pustular psoriasis frequently makes the correct diagnosis problematic. In addition, treatment is limited by a relative lack of evidence-based therapeutic options. Current management is often based on existing therapies for standard plaque psoriasis. However, there remains a need for treatments with high, sustained efficacy and a rapid onset of action in pustular psoriasis. Recent advances in understanding of the pathogenesis of pustular psoriasis have provided insights into potential therapies. Treatment of pustular psoriasis is generally determined by the extent and severity of disease, and recent years have seen an increasing use of newer agents, including biologic therapies. Current classes of biologic therapies with US Food and Drug Administration and European Medicines Agency approval for treatment of moderate-to-severe plaque psoriasis in the USA (and elsewhere) include tumor necrosis factor alpha inhibitors (adalimumab, certolizumab pegol, etanercept, infliximab), interleukin (IL)-17 inhibitors (brodalumab, ixekizumab, secukinumab), an IL-12/23 inhibitor (ustekinumab), and IL-23 inhibitors (guselkumab, risankizumab, tildrakizumab). Recently, specific inhibitors of the IL-36 pathway have been evaluated in GPP and PPP, including spesolimab, an IL-36 receptor inhibitor which has shown promising results in GPP. The emerging drugs for pustular psoriasis offer the possibility of rapid and effective treatment with lower toxicities than existing therapies. Further research into agents acting on the IL-36 pathway and other targeted therapies has the potential to transform the future treatment of patients with pustular psoriasis. This article reviews the clinical features of PPP and GPP, and current understanding of the genetics and immunopathology of these conditions; it also provides an update on emerging treatments. Pustular psoriasis is a skin condition where people develop small pus-filled blisters on their skin. Pustular psoriasis may affect certain areas of the body, such as the palms and/or the soles. This is called palmoplantar pustulosis (PPP for short). Another type of pustular psoriasis can affect most of the body called generalized pustular psoriasis (GPP for short). Not many people have PPP or GPP. Around 5–12 in every 10,000 people worldwide develop PPP. GPP is even rarer, affecting only 2–7 out of every 1 million people. In addition to being relatively uncommon, these conditions are challenging to treat. This article aims to help doctors who treat skin conditions (dermatologists) to identify and treat people with pustular psoriasis. Currently there is no standard treatment for GPP and PPP in the USA or Europe, but several medicines are approved for treatment of GPP in Japan. Doctors often use treatments that have been shown to work in plaque psoriasis, which is the most common type of psoriasis, to treat people with GPP and PPP. Traditional treatments for PPP and GPP are often not effective. Researchers are working on developing new effective treatments for pustular psoriasis that may work more rapidly and have fewer side effects. These are expected to be available in the next few years.
