Psoriatic disease (PsD) is a chronic disease affecting skin (psoriasis) and joints (psoriatic arthritis, PsA) that has a significant impact on patients\' quality of life (QOL). We report findings from the Japanese subgroup of patients included in Psoriasis and Beyond: The Global Psoriatic Disease Survey, a cross-sectional, quantitative online survey of patients with self-reported, healthcare professional (HCP)-diagnosed, moderate-to-severe plaque psoriasis, with or without PsA. Eligible patients who were recruited online completed a 25-min internet-based survey in Japanese. We assessed patients\' understanding of the systemic nature of PsD, disease burden, perception towards their HCPs, treatment expectations, and satisfaction with care. Of the 148 patients, 74% were females. In total, 65% of patients were aware of the systemic nature of their disease. A minority of patients (27%) were aware that PsA was related to their psoriasis, and 30% and 42% of patients were unaware of any manifestations and comorbidities, respectively, related to PsD. Overall, 21% of patients reported that their disease has a \"very large\" to \"extremely large\" impact on their QOL (assessed by Dermatology Life Quality Index score), while the majority (61%) reported a \"small\" effect or \"no effect\" at all on QOL. Patients experienced stigma and discrimination and had a negative impact on relationships due to PsD. More patients with psoriasis and concomitant PsA (66%) were satisfied with their current treatment than those with psoriasis alone (46%). Overall, 41% of patients were not involved in deciding their treatment goals. These results suggest that Japanese patients may not be fully aware of the systemic nature of PsD, its manifestations and comorbidities. While these patients were somewhat satisfied with their current treatment, they were only occasionally consulted in deciding treatment goals. Policy measures are required to address the stigma and discrimination experienced by patients. Increased patient participation in their care supports shared decision-making and enhanced treatment outcomes.

Psoriatic disease, encompassing both psoriasis (Pso) and psoriatic arthritis (PsA), is closely intertwined with a significantly elevated risk of developing cardiovascular diseases. This connection is further compounded by a higher prevalence of cardiometabolic comorbidities, including type 2 diabetes, obesity, insulin resistance, arterial hypertension, and dysregulated lipid profiles. These comorbidities exceed the rates seen in the general population and compound the potential for increased mortality among those living with this condition. Recognizing the heightened cardiometabolic risk inherent in psoriatic disease necessitates a fundamental shift in the treatment paradigm. It is no longer sufficient to focus solely on mitigating inflammation. Instead, there is an urgent need to address and effectively manage the metabolic parameters that have a substantial impact on cardiovascular health. Within this context, apremilast emerges as a pivotal treatment option for psoriatic disease. What sets apremilast apart is its dual-action potential, addressing not only inflammation but also the critical metabolic parameters. This comprehensive treatment approach opens up new opportunities to improve the well-being of people living with psoriatic disease. This review delves into the multifaceted aspects involved in the development of cardiovascular disease and its intricate association with psoriatic disease. We then provide an in-depth exploration of the pleiotropic effects of apremilast, highlighting its potential to simultaneously mitigate metabolic complications and inflammation in individuals affected by these conditions.

Despite observational studies suggesting a link between psoriatic disease (including psoriasis and psoriatic arthritis) and migraine, it is unclear whether there is a shared genetic etiology or a causal relationship between the two conditions. We aimed to reveal the genetic overlap and causality using the Mendelian randomization (MR) framework. The genetic analysis utilized summary data from the most extensive European genome-wide association study (GWAS) of migraine. Well-powered psoriatic disease GWAS data were obtained from two independent cohort studies, which served as discovery and validation datasets. Global and regional genetic correlations between psoriatic disease and migraine were assessed, and pleiotropic regions identified by pairwise GWAS analysis were further annotated. We further applied a two-sample MR multivariate MR to investigate the potential causal relationship between them. The global genetic correlation test indicated weak correlations between psoriatic disease and migraine, while regional correlation analyses delineated one significant shared locus between psoriasis and migraine. Pathway enrichment analysis revealed that shared genes were involved biological processes to the major histocompatibility and antigen processing and presentation. In terms of causality estimates, genetically predicted psoriasis (Pmeta = 0.003) and psoriatic arthritis (Pmeta = 0.028) were associated with an increased risk of migraine. Multivariate MR analysis indicated that psoriasis was an independent risk factor for migraine (P < 0.05). No significant associations were found in the reverse direction. Our study supported the causal role of psoriasis on migraine, and the central role for immunomodulatory etiology. These findings have significant implications for the management of migraine and clinical practice in patients with psoriasis.

UNASSIGNED: Circulating T follicular helper (cTfh) cells and circulating T peripheral helper (cTph) cells (which share common characteristics with the cTfh population) are implicated in the pathogenesis of immune-mediated and autoimmune diseases such as psoriasis (Ps). Their close interplay with the interleukin 17 (IL-17) axis and the ex vivo effect of IL-17-targeting biologic agents used to treat Ps on them are elusive. This study aimed to investigate the effect of biologics targeting IL-17 on cTfh and cTph cell subpopulations isolated from the blood of patients with Ps.
UNASSIGNED: Peripheral blood mononuclear cells (PBMCs) were isolated from patients with Ps at treatment initiation and three months later. Samples were also collected from controls. Cells were stained using monoclonal antibodies. Flow cytometry assessed the fraction of cTfh (CD3+CD4+CXCR5+) and cTph (CD3+CD4+CXCR5-PD-1hi) cells..
UNASSIGNED: Flow cytometric analysis showed increased fractions of activated cTfh subsets including ICOS+ and ICOS+PD-1+ expressing cells, in patients compared to controls. Biologic blocking of IL-17A diminished the cTfh population. Furthermore, ICOS+ and ICOS+PD-1+ sub-populations were also inhibited. Finally, the cTph cell fraction significantly decreased after three months of successful treatment with biologics.
UNASSIGNED: Early anti-IL-17-mediated clinical remission in Ps is associated with decreased cTfh and cTph cell subpopulations.

Limited information is available on the effectiveness of COVID-19 vaccination in patients with psoriasis and psoriatic arthritis (psoriatic disease (PsD)). The objective of our research was to assess the effectiveness of mRNA COVID-19 vaccination in preventing SARS-CoV-2 positivity and severe infection in a cohort of patients with PsD and the association of immunosuppressants on SARS-CoV-2 infection-related outcomes from December 2020 to December 2021. Vaccine effectiveness was assessed in a matched nested case control study using conditional logistic regression adjusted for demographics, comorbidities and immunosuppressant use. Study outcomes included SARS-CoV-2 positivity and severe COVID-19 (moderate-to-severe COVID-19-related hospitalizations or death). At least one dose of mRNA COVID-19 vaccine was associated with reduced risk of SARS-CoV-2 positivity and severe COVID-19 (OR = 0.41 (95% CI, 0.38-0.43) and OR = 0.15 (95% CI, 0.11-0.20), respectively). A more significant effect was found among patients who received three vaccines doses compared with those who did not receive any (OR (for positive SARS-CoV-2) = 0.13 (95% CI, 0.12-0.15) and OR (for severe disease) = 0.02 (0.01-0.05)). Etanercept and methotrexate were associated with higher risk of SARS-CoV-2 positivity (1.58 (1.19-2.10), p = 0.001 and 1.25 (1.03-1.51), p = 0.03, respectively). In conclusion, our results show that mRNA COVID-19 vaccines are effective in reducing both infection and severe COVID-19-related outcomes.

UNASSIGNED: Psoriasis is an inflammatory skin disease that in some cases is accompanied by systemic manifestations. Given the varied clinical manifestations, the term psoriatic disease probably better reflects the clinical picture of these patients.
UNASSIGNED: In most cases, the skin lesions precede joint involvement as well as other potentially involved organs such as the intestine and the eye. Various immune-mediated cellular pathways such as that of TNFα, IL-23, IL-17 as well as other cytokines are involved in the pathophysiology of the psoriatic disease.
UNASSIGNED: A better understanding of the way they interfere with our immune system has led to remarkably better disease control and outcomes. This review aims to highlight the newest treatments for psoriatic disease, which are expected to significantly reduce unmet needs and treatment gaps.

UNASSIGNED: Psoriatic disease (PsD), including plaque psoriasis (PsO) and psoriatic arthritis (PsA), comprises a wide spectrum of manifestations and significantly impacts quality-of-life (QoL). Here, we assessed patients\' understanding of PsO and PsA as a systemic disease, its impact on their physical and emotional well-being, and patients\' experiences with healthcare professionals for shared treatment decision-making.
UNASSIGNED: The Global Psoriatic Disease and Beyond Survey was a cross-sectional, qualitative, online survey conducted on patients with moderate-to-severe PsO with/without concomitant PsA. This analysis reports findings from Indian patients.
UNASSIGNED: Of the 261 surveyed patients, 27% with PsO reported concomitant PsA, of whom 89% reported PsA severity as moderately or highly active. Overall, 92% had heard the term \"PsD,\" and 90% knew their condition was a systemic disease. Few were aware of PsD manifestations (palmoplantar psoriasis, 49%; nail psoriasis, 43%; axial symptoms, 40%; PsA, 34%) and comorbidities (cardiovascular disease, 33%; obesity, 30%; diabetes, 28%). Eighty-nine percent of patients indicated their skin problems had a \"very-large\" to \"extreme-large\" impact on QoL. Ninety-seven percent of patients experienced discrimination and stigmatization from others. Eighty-one percent of patients were not involved in deciding treatment goals. Few (PsO, 6%; PsA, 9%) patients were dissatisfied with current treatment; ≥50% patients reported incomplete relief of skin symptoms (PsO) and joint symptoms (PsA) as the reason for dissatisfaction.
UNASSIGNED: Lack of awareness of the manifestations and comorbidities associated with PsD and poor QoL highlights the need for patient education, shared treatment decision-making, and a multidimensional approach to PsD management in India.
