Abstract
Inflammatory skin diseases include a series of disorders characterized by a strong activation of the innate and adaptive immune system in which proinflammatory cytokines play a fundamental role in supporting inflammation. Skin inflammation is a complex process influenced by various factors, including genetic and environmental factors, characterized by the dysfunction of both immune and non-immune cells. Psoriasis (PS) and atopic dermatitis (AD) are the most common chronic inflammatory conditions of the skin whose pathogeneses are very complex and multifactorial. Both diseases are characterized by an immunological dysfunction involving a predominance of Th1 and Th17 cells in PS and of Th2 cells in AD. Suppressor of cytokine signaling (SOCS) proteins are intracellular proteins that control inflammatory responses by regulating various signaling pathways activated by proinflammatory cytokines. SOCS signaling is involved in the regulation and progression of inflammatory responses in skin-resident and non-resident immune cells, and recent data suggest that these negative modulators are dysregulated in inflammatory skin diseases such as PS and AD. This review focuses on the current understanding about the role of SOCS proteins in modulating the activity of inflammatory mediators implicated in the pathogenesis of inflammatory skin diseases such as PS and AD.

Polymorphisms of the GCLC Gene Are Novel Genetic Markers for Susceptibility to Psoriasis Associated with Alcohol Abuse and Cigarette Smoking. Life (Basel) 2023; 13:1316. [PMID: 37374099 DOI: 10.3390/life13061316] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/06/2023] [Revised: 05/23/2023] [Accepted: 06/01/2023] [Indexed: 06/29/2023] Open
Abstract
The aim of this pilot study was to investigate whether single nucleotide polymorphisms (SNP) in the gene encoding the catalytic subunit of glutamate cysteine ligase (GCLC) are associated with the risk and clinical features of psoriasis. A total of 944 unrelated individuals, including 474 patients with a diagnosis of psoriasis and 470 healthy controls, were recruited for the study. Six common SNPs in the GCLC gene were genotyped using the MassArray-4 system. Polymorphisms rs648595 (OR = 0.56, 95% CI 0.35-0.90; Pperm = 0.017) and rs2397147 (OR = 0.54, 95% CI 0.30-0.98; Pperm = 0.05) were associated with susceptibility to psoriasis in males. In the male group, diplotype rs2397147-C/C × rs17883901-G/G was associated with a decreased risk of psoriasis (FDR-adjusted p = 0.014), whereas diplotype rs6933870-G/G × rs17883901-G/G (FDR-adjusted p = 0.045) showed an association with an increased disease risk in females. The joint effects of SNPs with tobacco smoking (rs648595 and rs17883901) and alcohol abuse (rs648595 and rs542914) on psoriasis risk were observed (Pperm ≤ 0.05). We also found multiple sex-independent associations between GCLC gene polymorphisms and various clinical features such as earlier disease onset, the psoriatic triad, and specific localizations of skin lesions. The present study is the first to show that polymorphisms of the GCLC gene are significantly associated with the risk of psoriasis and related to its clinical features.

Abstract
The systemic treatment of psoriasis has changed markedly with the introduction of many novel drugs. However, clinicians have had limited opportunities to evaluate these new therapies. One of the new drugs, apremilast (a phosphodiesterase-4 inhibitor), was approved in 2017 in Japan. We previously reported oral treatment for psoriasis before the introduction of apremilast. In this study, we investigated the impact of apremilast on oral medication for psoriasis by comparing data obtained before and after apremilast became available. This retrospective study enrolled patients who visited the Department of Dermatology, Fukuoka University Hospital, who were diagnosed with psoriasis and treated with anti-psoriatic oral medications. Patients were divided into two groups: Group 1, who first visited our clinic between January 2010 and March 2016; and Group 2, who first visited our clinic between April 2016 and March 2022. The information collected included patient demographics, drug use (apremilast, cyclosporine, methotrexate, and etretinate), and treatment duration. In Group 1 (n = 149 patients), cyclosporine, methotrexate, and etretinate were prescribed to 59.1%, 16.6%, and 24.3% of the patients, respectively. In Group 2 (n = 129 patients), apremilast was prescribed to 52.5% of patients, while the number of prescriptions for cyclosporine and etretinate had decreased to 17.1% and 8.3%, respectively. The number of methotrexate prescriptions did not change significantly. Apremilast, methotrexate, and etretinate had longer continuation rates than cyclosporine in Group 2. In conclusion, apremilast replaced cyclosporine and etretinate mainly because of its better safety profile, whereas methotrexate remained in constant demand in both eras. New oral treatments for psoriasis, such as tyrosine kinase-2 inhibitors, are now in the pipeline, and our data will serve as a control for oral anti-psoriatic medicine before the coming era.

Abstract
The real-world treatment landscape for patients with moderate-to-severe psoriasis receiving systemic therapies in Japan is not well understood. This study describes the demographic and clinical characteristics, treatment patterns, healthcare resource utilization, and psoriasis-associated costs in these patients. This retrospective observational study used data from the Japan Medical Data Center database between January 2016 and December 2020. Eligible patients had a confirmed diagnosis of psoriasis, ≥1 claim for a systemic treatment of interest, medical history for ≥6 months, and follow-up data for ≥12 months. Systemic therapies comprised biologics (tumor necrosis factor and interleukin inhibitors) and oral treatments (a phosphodiesterase-4 inhibitor, immunosuppressants, and vitamin A). Patient demographics and clinical characteristics, treatment patterns, healthcare resource utilization, and costs were evaluated. The study identified 1770 patients satisfying all inclusion criteria. The mean age was 49.0 years, with 68% of patients aged 20-54 years. Overall, 90.6% and 9.4% of patients received oral medications and biologics as index treatment, respectively. Treatment patterns, healthcare resource utilization, and costs were assessed for treatments received by ≥20 patients (n = 1730). During the 12-month follow-up period, 1102/1730 patients (63.7%) discontinued index treatment, of whom 9.9% switched to alternative systemic treatments. The persistence rate was ≥70% for most biologics and <50% for oral systemic treatments. All 1730 patients had ≥1 all-cause outpatient visit (2.0 visits per person per month) and hospitalization frequency was ≤0.01 per person per month. Persistent patients incurred inflation-adjusted costs of Japanese Yen (JPY) 88 667 per person per month. Treatment switching was associated with an increase in total cost: JPY 128 039 per person per month after switching versus JPY 117 504 before switching. This study of Japanese patients with moderate-to-severe psoriasis demonstrated low persistence, high discontinuation, and low rates of treatment switching with systemic therapies. Switching was associated with increased total cost. These results indicate unmet needs for new treatments.

Abstract
Psoriasis is a common chronic inflammatory skin disease of the interleukin (IL)-23/IL-17 axis. The severity of psoriasis has been reported as higher in men than in women. The immunoregulatory role of female sex hormones has been proposed to be one of the factors responsible for sex differences. Among female sex hormones, estrogens have been suggested to be significantly involved in the development of psoriasis by various epidemiological and in vitro studies. For example, the severity of psoriasis is inversely correlated with serum estrogen levels. In vitro, estrogens suppress the production of psoriasis-related cytokines such as IL-1β and IL-23 from neutrophils and dendritic cells, respectively. Furthermore, a recent study using a mouse psoriasis model indicated the inhibitory role of estrogens in psoriatic dermatitis by suppressing IL-1β production from neutrophils and macrophages. Understanding the role and molecular mechanisms of female sex hormones in psoriasis may lead to better control of the disease.

Abstract
The efficacy and safety of new psoriatic treatments are confirmed in clinical trials, but such clinical trial data are limited by the number and heterogeneity of patients. Furthermore, the prevalence and characteristics of psoriasis differ among racial groups. Therefore, it is important to obtain real-world evidence in specific regions. To identify the optimal systemic treatment for psoriatic patients in Western Japan, we established the Western Japan Psoriasis Registry (WJPR). This registry is led by a neutral physicians' league associated with university hospitals, general hospitals, and clinics that specialize in treatment of psoriasis. Systemically treated psoriatic patients who provided written informed consent were enrolled, and data were collected on their background information, several patient-reported outcomes, dermatologists' objective evaluations, and treatment regimens. Patient enrollment began in 2019, and 1394 patients had been recruited by the end of 2020. The prevalence of psoriatic arthritis was 27.2% and that of pustular psoriasis was 7.5%. The mean body mass index was 24.1 kg/m2 , and 12% of patients had severe obesity (body mass index ≥30 kg/m2 ). Major comorbidities were hypertension (35.0%), diabetes (14.1%), and hyperlipidemia (12.2%). Serological data showed that hepatitis B virus surface antigen, anti-hepatitis B virus core antibody, anti-hepatitis C virus antibody, and human T-cell leukemia virus type 1 antibody were detected in 1.1%, 18.0%, 3.1%, and 3.7% of patients, respectively. The most frequently used small-molecule-systemic intervention was apremilast (18.0%), followed by methotrexate (7.7%), etretinate (4.2%), and cyclosporin (3.7%). The most frequently used biologics were interleukin (IL)-17 inhibitors (31.8%), followed by IL-23 inhibitors (including IL-12/23 inhibitors) (26.7%), and tumor necrosis factor inhibitors (11.1%). The WJPR is the first Japanese prospective observational cohort of psoriatic patients. Annual WJPR updates may provide the incidences of comorbidities such as cardiovascular events or onset of arthritis in systemically treated patients, identify rare complications, and identify the optimal treatment regimens for various psoriatic patients.

Abstract
In Japan, the Japanese Society for Psoriasis Research (JSPR) has been conducting annual epidemiological surveys of patients with psoriasis since 1982. The aim of this study was to conduct a recent epidemiological analysis of the psoriasis patients who were enrolled in the JSPR from 2013 to 2018. A total of 15 287 cases were enrolled from 132 medical institutions, out of which 65.3% (9989 cases) were male and 34.7% (5298 cases) were female. Approximately 50.0% of the cases had past history and comorbidities, such as hypertension (42.0%), dyslipidemia (30.0%), diabetes mellitus (23.7%), hyperuricemia (15.1%), cardiovascular disease (6.0%), and cerebral vascular disorders (6.0%). There was a yearly increase in the use of corticosteroid/vitamin D3 combinations and apremilast for treating psoriasis. In contrast, the use of phototherapy gradually decreased. From 2013 to 2018, approximately 18.6% of the cases were treated with biologics, such as infliximab (17.6%), adalimumab (23.3%), ustekinumab (21.4%), secukinumab (11.6%), ixekizumab (7.6%), brodalumab (6.3%), and guselkumab (4.3%). In the past decade, the biologics have changed the treatment and management of psoriasis. This survey includes significant information regarding the recent perspective of psoriasis in the Japanese Society, especially focusing on the treatment trends after the introduction of biologics.

Abstract
Introduction Psoriasis is a chronic disease. Research shows the emergence of harmful habits such as cigarette smoking and alcohol consumption in people with psoriasis. Aim The aim of this study was to determine the frequency of habits, cigarette smoking and alcohol consumption in patients with psoriasis, sexual distribution, and the relationship of habits with the severity of the disease. Methods The prospective study included 129 subjects with psoriasis, of which 67 or 51,94% were women and 62 or 48,06% were men. Results The frequency of cigarette smoking was 41,09%, alcohol consumption 24,80%. The gender distribution of cigarette smoking was: 35,82% of women and 46,77% of men smoked cigarettes. The gender distribution of alcohol consumption is: women 5,97% and men 45,16%. The severity of psoriasis, that is PASI score and cigarette smoking were statistically significantly related (r=0,63), and PASI score and alcohol consumption were not statistically significantly related (r=0,32). Conclusion Cigarette smoking and alcohol consumption are present in psoriasis sufferers, cigarette smoking is associated with disease severity, and alcohol consumption is not. It takes knowledge of the habits of people with psoriasis and a multidisciplinary approach to get rid of harmful habits.

Abstract
The excellent clinical efficacy of anti-interleukin 17A (IL-17A) biologics on psoriasis indicates a crucial pathogenic role of IL-17A in this autoinflammatory skin disease. IL-17A accelerates the proliferation of epidermal keratinocytes. Keratinocytes produce a myriad of antimicrobial peptides and chemokines, such as CXCL1, CXCL2, CXCL8, and CCL20. Antimicrobial peptides enhance skin inflammation. IL-17A is capable of upregulating the production of these chemokines and antimicrobial peptides in keratinocytes. CXCL1, CXCL2, and CXCL8 recruit neutrophils and CCL20 chemoattracts IL-17A-producing CCR6+ immune cells, which further contributes to forming an IL-17A-rich milieu. This feed-forward pathogenic process results in characteristic histopathological features, such as epidermal hyperproliferation, intraepidermal neutrophilic microabscess, and dermal CCR6+ cell infiltration. In this review, we focus on IL-17A and keratinocyte interaction regarding psoriasis pathogenesis.

Abstract
Psoriasis is a chronic inflammatory disease caused by both genetic and environmental factors. The occurrence of psoriasis in family members indicates a genetic predisposition, while obesity is also a major contributor to psoriasis. We examined whether patients with versus without familial psoriasis were obese at the onset of psoriasis. Clinical information, including age at onset, age at first visit and body mass index (BMI) at first visit, was extracted from the Fukuoka University Psoriasis Registry. To compare BMI, patients aged 10 years or older who visited the clinic within 3 years of onset were selected. Familial psoriasis was observed in 27 patients (15 male, 12 female) out of 428 individuals (264 male, 164 female) with psoriasis, accounting for 6.3% of cases. Age at onset was younger for both men and women with familial psoriasis (34 ± 17 and 40 ± 15 years, respectively) relative to those with non-familial psoriasis (48 ± 19 and 53 ± 19 years, respectively). We examined age- and sex-adjusted average values of BMI at initial presentation after onset of psoriasis, finding that patients with familial psoriasis had lower BMI (22.0 kg/m2 [95% confidence interval, 21.8-22.4]) than those with non-familial psoriasis (23.2 [23.1-23.3], P < 0.001). Individuals with a family history of psoriasis should be considered to be at risk for developing the disease even if obesity is not present.

Abstract
Psoriasis is a TNF-α/IL-23/IL-17A-mediated inflammatory skin disease that causes a significant socioeconomic burden in afflicted patients. IL-17A-producing immune cells, including Th17 cells, are crucial effector cells in the development of psoriasis. IL-17A stimulates epidermal keratinocytes to produce CCL20, which eventually recruits CCR6 + Th17 cells into the lesional skin. Thus, the CCL20/CCR6 axis works as a driving force that prepares an IL-17A-rich cutaneous milieu. In this review, we summarize the current research topics on the CCL20/CCR6 axis and the therapeutic intervention of this axis for psoriasis.

Aryl Hydrocarbon Receptor in Atopic Dermatitis and Psoriasis. Int J Mol Sci 2019; 20:ijms20215424.

Abstract
The aryl hydrocarbon receptor (AHR)/AHR-nuclear translocator (ARNT) system is a sensitive sensor for small molecular, xenobiotic chemicals of exogenous and endogenous origin, including dioxins, phytochemicals, microbial bioproducts, and tryptophan photoproducts. AHR/ARNT are abundantly expressed in the skin. Once activated, the AHR/ARNT axis strengthens skin barrier functions and accelerates epidermal terminal differentiation by upregulating filaggrin expression. In addition, AHR activation induces oxidative stress. However, some AHR ligands simultaneously activate the nuclear factor-erythroid 2-related factor-2 (NRF2) transcription factor, which is a master switch of antioxidative enzymes that neutralizes oxidative stress. The immunoregulatory system governing T-helper 17/22 (Th17/22) and T regulatory cells (Treg) is also regulated by the AHR system. Notably, AHR agonists, such as tapinarof, are currently used as therapeutic agents in psoriasis and atopic dermatitis. In this review, we summarize recent topics on AHR related to atopic dermatitis and psoriasis.

Ito K, Bayaraa B, Imafuku S. Relationship between the efficacy of biologics and clinical plaque psoriasis subtypes in Japanese patients: A single-center pilot study. J Dermatol 2019; 46:1160-1165. [PMID: 31556161 DOI: 10.1111/1346-8138.15089] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/18/2019] [Accepted: 08/19/2019] [Indexed: 01/01/2023]
Abstract
Although biologics for plaque psoriasis brought epoch-making efficacy, not all patients achieve treatment success with all reagents. The aim of this study was to clarify the correlation between clinical plaque psoriasis subtypes, age at onset, and the efficacy of biologics. Clinical records for patients with plaque psoriasis at Fukuoka University Hospital were reviewed retrospectively. The efficacy of biologics was compared using the survival of the first biologics administered in treatment-naïve patients. The survival of infliximab, adalimumab, and ustekinumab were followed until December 2016. The patients were clinically classified into three subtypes: small, large, or gigantic plaques using the size of the plaques on the back; early onset psoriasis (EOP, onset <40 years); or late-onset psoriasis (LOP, ≥40 years). Eighty-seven patients were enrolled. The survival of biologics was significantly better in large plaques compared with small or gigantic plaques (P = 0.0007). In patients treated with tumor necrosis factor (TNF) inhibitors, large plaques had significantly better survival than did the other types (P = 0.0122), while ustekinumab showed good survival in all three subtypes. The survival of biologics was numerically better in EOP than in LOP, but this was not significant. The efficacy of TNF inhibitors was different among clinical subtypes. Psoriatic patients with small plaques may be less responsive to TNF inhibitors. Further studies are needed.

Abstract
Psoriasis is an (auto)immune-mediated disease that manifests as widespread
desquamative erythema. The TNF-α/IL-23/IL-17A axis is crucial to its
pathogenesis, which is demonstrated by its excellent therapeutic response to
biologics that target this axis. There is a strong association between
HLA-C*0602 and psoriasis, and researchers have identified autoantigens that are
restricted to this major histocompatibility class I molecule. These auto-Ags
include LL-37, A disintegrin and metalloprotease domain containing
thrombospondin type 1 motif-like 5 (ADAMTSL5), and keratin 17. IL-17A-producing
T cells have been identified in T cell populations that are reactive to these
auto-Ags. In addition, lipid Ags have surfaced as candidate auto-Ags that
activate IL-17A-producing T cells in a CD1a-restricted manner. In this article,
we review the candidate auto-Ags that may contribute to the activation of the
IL-17A-deviated immune response in psoriasis.

Abstract
Biologics are efficacious for treating psoriasis vulgaris (PsV) and psoriatic arthritis (PsA), but sometimes must be terminated or changed for various reasons including ineffectiveness or adverse events. To find the optimal choice of biologics for treating psoriasis, we analyzed the real-world data on drug survival and the reason for terminating or switching biologics. Medical records from patients with PsV or PsA, who visited the Department of Dermatology, Fukuoka University Hospital from 2010 to 2017, were analyzed. Two hundred and eleven patients received biologics, and 147 patients (69.7%) were treated with only one biologic, while 64 patients (30.3%) were switched to different products. Frequently used biologics in PsV were ustekinumab (UST), infliximab and adalimumab when calculated by patient-year. Tumor necrosis factor inhibitor (TNFi) use decreased while UST and interleukin (IL)-17 inhibitors increased in newly introduced patients. UST showed the highest survival rate as a first-line drug, but the advantage was lost in the second reagent's group. The major reasons for terminating/switching biologics were as follows: primary ineffectiveness (26.4%), secondary loss of efficacy (36.5%), patient's preference, including referral to nearby hospital, or stopped visiting (22.6%), side-effects (7.7%), comorbidities (3.4%) and economic burden (2.4%). In PsA patients, TNFi are more frequently employed than in PsV patients, although switching to UST or IL-17 inhibitors showed an increasing trend. Biologic reagents were changed mostly because of primary or secondary loss of efficacy, which affected drug survival. Further research is needed to find the optimal choice of biologics with larger samples at multiple facilities.
