A prospective Real-Life Multicenter Study of Tildrakizumab 200 mg in Patients with Moderate-Severe Psoriasis: Who is the Ideal Patient?

Tildrakizumab, a humanized monoclonal antibody targeting the p19 subunit of interleukin 23 (IL-23), has shown promise in the management of moderate-to-severe plaque psoriasis, offering potential improvements in clinical outcomes and quality of life. The study aimed to identify patient characteristics that indicate the initiation of a 200 mg dosage of tildrakizumab in a real-world setting, focusing on factors that enhance treatment effectiveness and safety. This prospective study included 54 adult patients with moderate-to-severe plaque psoriasis treated with tildrakizumab 200 mg from March 2023 to March 2024 across 13 Italian Dermatology Units. Data collected included demographics, disease duration, comorbidities, and previous treatments. PASI, BSA, and DLQI scores were recorded at baseline and at weeks 4, 16, and 28. Safety was assessed through adverse event reporting. Univariate analysis was performed to identify baseline characteristics significantly associated with achieving PASI ≤ 5 at week 16. Significant reductions in PASI scores were observed at week 4 (9 ± 6.9, P < 0.001), with further improvements at weeks 16 (3.9 ± 4.2, P < 0.001) and 28 (2.9 ± 4.4, P < 0.001). Univariate analysis showed that obese patients (BMI > 30) had higher odds (OR = 4.333, P < 0.05) of achieving PASI ≤ 5. Longer disease duration and starting with a 100 mg dosage also correlated with better outcomes. The safety profile was favorable, with minimal adverse events reported. Tildrakizumab 200 mg is effective and safe for moderate-to-severe psoriasis, particularly in obese patients. These findings support its use as a long-term treatment option.

Prevalence and Incidence of Psoriatic Arthritis among Patients with Psoriasis and Risk Factors for Psoriatic Arthritis in Republic of Korea: A Nationwide Database Cohort Study.

Population-based epidemiological studies on disease burden and risk factors for psoriatic arthritis (PsA) in patients with psoriasis (PsO) are limited, especially in Asian populations. Therefore, the aim was to determine the prevalence and incidence of PsA among PsO patients in Korea, and examine associated clinical factors. A cohort study was performed to determine the annual prevalence and incidence of PsA among PsO patients between 2008 and 2020 using nationwide claims data in Korea. Risk factors for PsA development were also examined using logistic regression among matched PsA cases and controls. An increasing trend in PsA prevalence per 1,000 patients was observed; prevalence was 6.17 (95% confidence interval [CI] 5.73-6.65) in 2008 and 19.03 (95% CI 18.39-19.70) in 2020. Similarly, the PsA incidence rate per 1,000 patient-years increased from 3.35 (95% CI 3.01-3.72) in 2008 to 5.01 (95% CI 4.68-5.36) in 2020. Patients with plaque PsO, moderate-to severe PsO, receiving oral systemic therapy or phototherapy, with a higher burden of comorbidities, and concomitant autoimmune diseases had a higher risk of PsA. The results provide insight into the burden of PsA among PsO patients in Korea and risk factors associated with developing PsA.

Efficacy and safety of biotechnological drugs for the treatment of moderate-to-severe psoriasis in the elderly population: a single-center, Italian experience.

Demographic changes impose a number of issues regarding the biological treatment of elderly patients with moderate-to-severe psoriasis. A retrospective, single-center study was conducted on patients aged 65 years or older with moderate-severe psoriasis who had been undergoing treatment with biologic drugs for at least 60 weeks. A total of 168 patients aged 65 years or older with moderate-to-severe psoriasis undergoing biologic therapy were retrieved: 45 were women and with a mean age of 73.23 ± 6.53 years. The decline in mean PASI, BSA, DLQI and NAPSI values over the 60 weeks of treatment was found to be statistically significant at each interval (p < 0.05). Multivariate statistical analysis showed that nearly all the considered independent variables did not influence the response to therapy in terms of PASI score reduction, except for psoriatic arthritis (p = 0.03). We observed a better response by YOs, with 72.84% of subjects achieving PASI 75 and 71.6% achieving PASI 90 and 100 at the 60th week of treatment. The worst result was obtained by the MOs, with 60 percent of subjects reaching PASI 75 at the end of follow-up, while the OOs had a more mixed performance. The results obtained seem to indicate greater efficacy of anti-TNFα drugs, followed by the other classes of interleukin inhibitors. These results could provide a starting point for new and larger studies and guidelines for biologic treatment.

Drug Survival, Safety, and Effectiveness of Secukinumab for up to 5 Years in Patients with Psoriasis and Psoriatic Arthritis: A Long-Term Real-Life Experience.

the selective IL-17 inhibitor secukinumab has demonstrated efficacy and safety in the treatment of moderate-severe psoriasis in recent years. evaluate effectiveness and drug survival (DS) of secukinumab in patients with psoriasis for up to 5 years. This is a retrospective study on a monocentric cohort of patients with psoriasis on secukinumab evaluating the achievement of PASI100, PASI90, and PASI ≤ 3 and DS analysis up to 260 weeks. DS multivariate analysis was carried out considering sex, age, age of onset of the disease, obesity, cardiovascular comorbidities, diabetes, involvement of difficult-to-treat sites, psoriatic arthritis, treatment-naïve status, and mean baseline PASI. At baseline, we evaluated 255 patients on secukinumab. PASI100 was reached by 41.7% and 70.6% of patients at weeks 16 and 260, respectively. PASI90 showed a similar trend with 46.5% of patients achieving it at week 16 and 88.2% at week 260. Non-obese patients showed a faster response than patients with obesity in achieving PASI100, PASI90, and PASI ≤ 3, with significant differences at 28 weeks [55% vs. 40% (p = 0.033), 64% vs. 49% (p = 0.038), and 76% vs. 62% (p = 0.036), respectively]. The estimated DS for secukinumab was 84.3% at 12 and 48% at 60 months. Obesity and smoking habits were associated with a higher risk of discontinuation in multivariate models (HR 1.6 CI 1.05-2.45, p = 0.028; HR 1.48 CI 1.01-2.17, p = 0.043, respectively). Secukinumab showed effectiveness for up to 5 years of treatment, with a high DS and achievement of PASI100, PASI90, and PASI < 3 at these time points. Only obesity reduced the response and maintenance of DS.

Association of hematological ratios with psoriasis: a nationwide retrospective cohort study.

Psoriasis is a common skin disorder linked to systemic inflammation and immune dysregulation. It is believed to involve activated T cells and neutrophils. Recent research has highlighted the potential role of hematological ratios, such as neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), eosinophil-to-lymphocyte ratio (ELR), eosinophil-to-neutrophil ratio (ENR), and eosinophil-to-monocyte ratio (EMR), as markers for inflammatory skin diseases, including psoriasis. We aimed to investigate hematological ratios between children and adults, patients and controls, and patients with moderate-to-severe and mild psoriasis. This national retrospective cohort study included over 16,000 psoriasis patients in Israel. Patients with comorbidities influencing blood counts were excluded. Ratios were calculated from blood counts taken within 30 days of diagnosis. Multivariable logistic regression, including age, gender, ethnicity, smoking status, and socioeconomic status, was performed. Findings revealed age-specific variations in blood counts, hematological ratios, and differences between mild and moderate-severe patients and patients versus controls. Moderate-severe psoriasis patients had elevated neutrophil and eosinophil counts (4.57 vs. 4.25, P < 0.001, and 0.24 vs. 0.22, P = 0.047, respectively), as well as increased NLR (2.46 vs. 2.29, P < 0.001). Multivariable logistic regression analysis confirmed the significance of neutrophil and platelet counts as well as NLR and PLR in predicting psoriasis severity. This was a retrospective study without subjective data on disease severity. This study highlights hematologic ratios' diagnostic and prognostic potential in psoriasis.

Real-world data on the effectiveness of brodalumab in patients with moderate-to severe plaque psoriasis in the Greek clinical setting (the BrIDGE study).

Despite that brodalumab's efficacy and safety have been assessed in randomized clinical trials, real-life data remain scarce. BrIDGE was an observational, prospective, single-cohort, multicentre study that recruited patients with moderate-to severe plaque psoriasis in Greece. The primary objective was to assess the proportion of patients who achieved Psoriasis Area and Severity Index (PASI)100 after 24 weeks. Other endpoints included: the maintenance of PASI90/100 through to 104 weeks, the short-term response [PASI75/90/100 and static Physician's Global Assessment (sPGA) 0/1] to brodalumab at 12-16 weeks and time to complete clearance. Moreover, we explored the change in quality of life [Dermatology Life Quality Index (DLQI) 0/1] and adherence to brodalumab. Two hundred patients who were initiating treatment with or switching to brodalumab, were recruited. Analyses were conducted using the as observed data and three imputation approaches were also applied for the missing data (last observation carried forward, 'worst case' and 'best case' scenario). Continuous variables were reported using summary statistics, whereas categorical variables were reported in frequency tables. Based on the 'as observed data', 42.0% of patients achieved PASI100 at Week 24 after 25.9 ± 3.5 weeks and 65% of patients attained PASI100 at Week 104. In total, 70.2%, 47.5% and 32.0% achieved PASI75/90/100, respectively, whereas 72.6% of patients achieved sPGA 0/1, at Weeks 12-16. With respect to sPGA status 82.8%, 89.2% and 92.5% of patients achieved sPGA 0/1 at Weeks 24, 52 and 104, respectively. The time to achieve PASI100 at Weeks 12-16 was 13.7 ± 1.3, 52.1 ± 3.4 weeks at Week 52 and 105.5 ± 4.8 weeks at Week 104. Mean DLQI and Psoriasis Symptom Inventory (PSI) scores decreased by 11.4 ± 7.0 and 15.4 ± 6.5 points from baseline to Week 104, respectively. Adherence to treatment was equal to 98.9%. Brodalumab confers rapid and durable responses, as well as improvements in the quality of life of moderate-to-severe psoriasis patients.

Racial and ethnic determinants of psoriatic arthritis phenotypes and disease activity.

Individuals of racially and ethnically diverse backgrounds are underrepresented in psoriatic arthritis (PsA) research/clinical trials, despite evidence that their disease presentation, severity and course may be distinct. Here we aim to describe how race, ethnicity and other socioeconomic factors inform disease characteristics in PsA. 817 consecutive patients with PsA from a large, diverse metropolitan area, were enrolled in an observational, longitudinal registry. Demographics, medical history, medication use, and psoriatic disease phenotype and activity were all recorded and analyzed. The population was 77.4% non-Hispanic White, 2.2% Black, 7.1% Asian, and 9.9% identified as other races or multiracial, and 11.8% identified as Hispanic. Hispanic and non-White individuals had higher tender joint counts (p= 0.033) with similar swollen joint counts (p= 0.308) and medication use (p= 0.171). They also had high rates of radiographic axial disease. Hispanic individuals were significantly more likely to have higher tender joint counts (p= 0.029), higher RAPID3 scores (p= 0.004), and moderate-severe psoriasis (p= 0.010) compared with non-Hispanic White individuals. In this diverse cohort, 22.6% of patients identified as underrepresented racial and/or ethnic groups, mostly Asian or Hispanic. Despite similar swollen joint counts and medication use, non-white individuals have higher tender joint counts compared with white individuals. Phenotypically, they also were more likely to have radiographic axial involvement. These findings may reflect differences in PsA presentation, experience and outcomes in individuals of various racial and ethnic groups, which need to be taken into consideration in clinical care and research design.

Rasch analysis of the dermatology life quality index (DLQI) in patients with mild to moderate-severe psoriasis.

Background The Dermatology Life Quality Index (DLQI) is a valuable tool for assessing the quality of life in adult patients with psoriasis. Aims To analyse the reliability and validity of the DLQI to measure the quality of life in patients with mild to moderate-severe psoriasis. Methods This was a secondary validation study nested in a follow-up study. The Rasch-Andrich model was utilised to perform response function, item and person fit, differential item functioning, dimensionality, and reliability analyses. Results A total of 1439 patients were analysed, 52.1% male, mean age of 48.7 years (SD 16.1). Psoriasis vulgaris was the phenotype in 43.1% of patients, and 86% had a mild Psoriasis Area Severity Index (PASI). Adequate adjustment of the response function and the items was observed in the best-fit sample, except for item 7 (work and study). The measure explained 60.9% of the variance and presented a reliability of 0.86. Differential item functioning was identified by age, with a relevant bias in the estimation for older adults. Item-person maps are provided. Limitations This study was performed at a single centre, with most patients presenting a mild PASI score, limiting generalisation of the findings. Conclusion The validity evidence favours the use of the DLQI in moderate-severe psoriasis. However, the instrument biases the estimate of older adults. This population group should consider a specific version of the instrument.

Effects of secukinumab combined with tretinoin on metabolism, liver enzymes, and inflammatory factors in patients with moderate to severe psoriasis vulgaris.

Psoriasis is a T cell-mediated polygenic chronic inflammatory disease. Interleukin (IL)-17A plays a major role in psoriasis pathogenesis. Secukinumab is a high-affinity human monoclonal antibody against IL-17A. This article explored efficacy and safety of secukinumab plus tretinoin in moderate to severe psoriasis (MSP) vulgaris, and assessed metabolism, liver function, and inflammation. A total of 135 patients diagnosed with moderate or severe psoriasis vulgaris were enrolled and randomized into three groups at a 1 : 1 : 1 ratio, receiving treatment with rretinoin, secukinumab, or combination therapy for a duration of 16 weeks. Psoriasis area and severity index (PASI) scores, serum T lymphocyte subsets, glucose, lipid, and uric acid (UA) metabolism, liver enzymes, and inflammatory factors (IFs) were measured. Following the therapy, subjects had decreased PASI scores, increased serum CD3+, CD4+, and CD4+/CD8+, decreased serum CD8+, and decreased serum UA and IL-2, IL-6, IL-23, interferon-γ (IFN-γ), and tumor necrosis factor (TNF)-α (p < 0.05). Total cholesterol, triglycerides, low-density lipoprotein, high-density lipoprotein, apolipoproteins A1, B, fasting blood glucose, alanine transaminase, aspartate transaminase, and alkaline phosphatase had no obvious differences among the subjects (p > 0.05). As against the Tretinoin and the Secukinumab groups, the PASI score was visiblysmaller, the changes in serum T lymphocyte subsets were more obvious, and serum UA and IFs were lower in the Combination group following the therapy (p < 0.05). Secukinumab combined with tretinoin is more effective in MSP vulgaris, which can visibly reduce inflammatory response without affecting glucose and lipid metabolism and liver function.

Association between several immune response-related genes and the effectiveness of biological treatments in patients with moderate-to-severe psoriasis.

Biological therapies are safer and more effective against psoriasis than conventional treatments. Even so, 30-50% of psoriatic patients show an inadequate response, which is associated with individual genetic heterogeneity. Pharmacogenetic studies have identified several single nucleotide polymorphisms (SNPs) as possible predictive and prognostic biomarkers for psoriasis treatment response. The objective of this study was to determine the link between several SNPs and the clinical response to biological therapies in patients with moderate-severe psoriasis. A set of 21 SNPs related to psoriasis and/or other immunological diseases were selected and analysed from salivary samples of patients (n = 88). Treatment effectiveness and patient improvement was assessed clinically through Relative Psoriasis Area and Severity Index (PASI), also called 'PASI response', as well as absolute PASI. Associations between SNPs and PASI factors were assessed at 3 and 12 months for every treatment category of IL-17, IL-23, IL-12&23 and TNF-α inhibitors. Multivariate correlation analysis and Fisher's exact test were used to analyse the relationship between SNPs and therapy outcomes. Several SNPs located in the TLR2, TLR5, TIRAP, HLA-C, IL12B, SLC12A8, TNFAIP3 and PGLYRP4 genes demonstrated association with increased short and long-term therapy-effectiveness rates. Most patients achieved values of PASI response ≥75 or absolute PASI<1, regardless of the biological treatment administered. In conclusion, we demonstrate a relationship between different SNPs and both short- and especially long-term effectiveness of biological treatment in terms of PASI. These polymorphisms may be used as predictive markers of treatment response in patients with moderate-to-severe psoriasis, providing personalized treatment.

Experience of using the interleukin-17A inhibitor secukinumab in the treatment of psoriasis and psoriatic arthritis

Psoriasis is a chronic immune-inflammatory skin disease, which in 25–30% of cases occurs in combination with damage of the musculoskeletal system ― psoriatic arthritis. Nowadays, the leading role in the pathogenesis of psoriasis and psoriatic arthritis is assigned to the activation of the IL-23/IL-17 axis-key cytokines involved in the activation pathway of the effector activity of Th17 lymphocytes. The activity of proinflammatory cytokines secreted by Th17 cells in psoriasis and psoriatic arthritis is also confirmed by the high efficiency of targeted therapy aimed specifically at this pathway. One of the modern genetically engineered biological drugs blocking IL-17 which is used worldwide in the treatment of psoriasis and psoriatic arthritis is secukinumab, a recombinant, fully human monoclonal antibody of high affinity directed against IL-17A.&#x0D; The article presents data from own 52-week follow-up of secukinumab use in 40 patients with severe and moderate-severe psoriasis which was combined with psoriatic arthritis in 67.5% of cases and demonstrates high efficacy, survival and satisfactory tolerability of this therapy.

Oxidative Stress and Inflammation Levels in a Population of Eastern European Naïve Versus Treated Psoriasis Patients.

Psoriasis is a chronic inflammatory disease, with a major impact on the patients' quality of life. Oxidative stress (OS) is represented by the imbalance between oxidant and antioxidant mechanisms of the organism, with increased levels being described in the majority of chronic diseases. We present the first prospective study in Romania to evaluate the redox balance changes (using a CR3000 analyzer) in patients with moderate-severe psoriasis based on treatment regimens: treatment-naïve (A), treatment with novel targeted agents (B) and methotrexate (C). The study group included 53 Caucasian patients divided into three groups (A- 27 patients, B - 15 patients, and C - 11 patients) for which OS, antioxidant status, standard blood count, and inflammatory status were evaluated. Our findings demonstrate that patients with psoriasis display high levels of OS, with elevated Free Oxygen Radical Test (FORT) (p-value for group A (pA)<0.0001, p-value for group B (pB)=0.0019 and p-value for group C (pC)=0.0063) and reduced Free Oxygen Radical Defense (FORD) (pB=0.018) values noted in our subjects. Higher erythrocyte sedimentation rate (ESR) values were detected in groups B (pB=0.00012) and C (pC<0.00001). Psoriasis treatments alleviate FORT and FORD levels, but their impact is not sufficient to restore the oxidative balance to normal ranges. Moreover, despite adequate treatment, patients with psoriasis display elevated inflammation levels. Future research should explore in more detail the interplay between OS and inflammation in psoriasis, namely the long-term impact on the redox balance of biotherapies.

Management Strategies for Pediatric Moderate-to-Severe Plaque Psoriasis: Spotlight on Biologics.

Although psoriasis onset has been reported at any ages, in up to one-third of cases, it begins during childhood, with an estimated prevalence of about 2% in pediatric population. The management of moderate-to-severe forms of childhood psoriasis may represent a challenge for dermatologists, especially for parents' concerns about the need of systemic treatments. However, a prompt safe and effective treatment is mandatory in these patients, due to the significative impact that psoriasis may have on their quality of life, with well-known consequences on psychological health of both patients and caregivers. Due to the relatively frequent parents' refusal of systemic treatments, probably due to the fear of eventual adverse events, difficulties of oral or injective route, the management of moderate-to-severe forms still represents a challenge. Herein, we report a narrative review, aiming to resume the systemic treatments for pediatric psoriasis, focusing on the use of biologics and small molecules in the pediatric ages. The most widely used therapeutic strategies today for the pediatric population with moderate-severe psoriasis are traditional systemic therapies, while more innovative drugs such as biologics and small molecules now represent a somewhat unexplored but certainly promising field for unresponsive patients.

Use of ustekinumab after other biological therapies in moderate-severe psoriasis: Real long-term data

ObjectiveUstekinumab is used in moderate-severe plaque psoriasis with inadequate response to anti-tumour necrosis factor a drugs. Recent studies support the need to assess real long-term data. The aim of this study was to evaluate the real long-term effectiveness and safety of ustekinumab in moderate-severe plaque psoriasis refractory to 2 anti-tumour necrosis factor a drugs. MethodRetrospective descriptive study from January 2010 to March 2019. The study included patients with moderate-severe plaque psoriasis previously treated with at least 2 anti-tumour necrosis factor a biologic drugs. The effectiveness endpoints were Psoriasis Area and Severity Index 90 and 75 response rates at weeks 24, 48, 72, and 96. Safety was assessed using adverse effects and treatment withdrawal. ResultsA total of 36 patients were included (men, 61%). Ustekinumab was used after treatment with 2 anti-tumour necrosis factor a drugs in 88.9% of patients. The biologic drugs most frequently administered prior to ustekinumab were infliximab (94.4%) and etanercept (91.7%). It was observed that at least 66.7% of patients reached Psoriasis Area and Severity Index 90 at weeks 24, 48, 72, and 96. Adverse effects were recorded in 6 patients. There were no treatment withdrawals. ConclusionsUstekinumab showed real long-term effectiveness and safety in moderate-severe plaque psoriasis with inadequate response to 2 previous anti-tumour necrosis factor a drugs.

Psoriasis seems often underdiagnosed in patient with axial spondyloarthritis

BackgroundAxial spondyloarthritis (axSpA) is known to be associated with several extra-skeletal manifestations (ESM), including the inflammatory skin disease psoriasis. It is important to recognize and diagnose psoriasis timely in axSpA in order to provide optimal treatment and outcome for both axSpA and psoriasis.MethodsIn this observational study, all patients from the Dutch Groningen Leeuwarden Axial Spondyloarthritis (GLAS) cohort included before June 2016 were sent a questionnaire with self-screening psoriasis questions including prototypical color pictures.ResultsOf the 592 questionnaires sent, 448 (75.7%) were eligible for analysis. Of these 448 respondents, 58 (13%) had a positive self-screening for psoriasis symptoms, currently or in the past. In 28 (48%) of 58 patients, psoriasis diagnosis could be verified by medical records, resulting in a psoriasis prevalence rate of 6.3%. In comparison with patients with a confirmed psoriasis diagnosis, patients reporting psoriasis symptoms without a verified diagnosis mentioned more mild than moderate-severe psoriasis symptoms (25% vs. 3%, p = 0.02), and their psoriasis lesions were less often located on the torso area (3% vs. 18%, p = 0.04), the intergluteal cleft (0% vs. 25%, p = 0.02), and legs (7% vs. 43%, p < 0.01). Of the 31 axSpA patients who reported currently active psoriasis, 74% had only mild psoriasis symptoms.ConclusionsEspecially mild psoriasis seems often underdiagnosed in patients with axSpA using a patient questionnaire with prototypical pictures of psoriasis lesions. This questionnaire could be beneficial in tracing patients with undiagnosed psoriasis in daily clinical practice. As a next step, further validation of this questionnaire is needed.

Australian consensus: Treatment goals for moderate to severe psoriasis in the era of targeted therapies – Adult patients

AbstractBackgroundOver the last decade, the treatment landscape for moderate–severe psoriasis has rapidly evolved. The Australasian College of Dermatologists sought to review and update previously published treatment goals for moderate–severe psoriasis.MethodsA modified Delphi approach was used. Comprehensive literature review and guideline evaluation resulted in the development of statements and other questions to establish current clinical practices. Two rounds of anonymous voting were undertaken, with a collaborative meeting held in between to discuss areas of discordance. Overall, consensus was defined as achievement of ≥75% agreement in the range 7–9 on a 9‐point scale (1 strongly disagree; 9 strongly agree).ResultsConsensus was achieved on 26/29 statements in round 1 and a further 20 statements in round 2. There was strong agreement to expanding the classification/definition of psoriasis severity by including a choice of metrics, incorporating quality of life measures, and widening the scope of high‐impact sites. Consensus was also reached on revised treatment response criteria, which were then incorporated into a new treatment algorithm. There was discordance with the current requirement to undertake a trial with established systemic agents before accessing targeted therapy.ConclusionThe ability of new targeted treatment options to change the narrative in psoriasis patient care can only be properly realised if challenges to timely and equitable access are addressed. The proposed framework for the assessment, classification and management of moderate–severe psoriasis aligns with international recommendations. Its adoption into Australian clinical practice is hoped to improve treatment outcomes and patients' satisfaction with their care.

Artículo traducido] Efectividad de guselkumab en pacientes con hidradenitis supurativa en condiciones de práctica clínica: estudio retrospectivo y multicéntrico en España

BackgroundHidradenitis suppurativa (HS) is a chronic skin condition causing lesions in which high levels of interleukin (IL)-23 and T-helper17 cells are found. Adalimumab remains the only approved treatment. Guselkumab, an antibody targeting the p19 protein subunit of extracellular IL-23, is approved for the treatment of moderate-severe psoriasis, but evidence on its efficacy in treating HS is limited. ObjectivesTo assess the effectiveness and safety of guselkumab in treating moderate-severe HS under clinical practice conditions. MethodsA multicentre retrospective observational study was carried out in 13 Spanish hospitals including adult HS patients treated with guselkumab within a compassionate use programme (March 2020-March 2022). Data referred to patient demographic and clinical characteristics at treatment initiation (baseline), patient-reported outcomes (Numerical Pain Rating Scale [NPRS] and Dermatology Life Quality Index [DLQI]), physician scores (International Hidradenitis Suppurativa Severity Score System [IHS4], HS Physical Global Score [HS-PGA] and Hidradenitis Suppurativa Clinical Response [HiSCR]) were recorded at baseline and at 16, 24, and 48weeks of treatment. ResultsA total of 69 patients were included. Most (84.10%) had severe HS (HurleyIII) and had been diagnosed for over ten years (58.80%). The patients had been subjected to multiple non-biological (mean: 3.56) or biological (mean: 1.78) therapies, and almost 90% of those treated with biologics had received adalimumab. A significant decrease in IHS4, HS-PGA, NPRS, and DLQI scores was observed from baseline to 48weeks of guselkumab treatment (all P<.01). HiSCR was achieved in 58.33% and 56.52% of the patients at 16 and 24weeks, respectively. Overall, 16 patients discontinued treatment, mostly due to inefficacy (n=7) or loss of efficacy (n=3). No serious adverse events were observed. ConclusionsOur results indicate that guselkumab may be a safe and effective therapeutic alternative for patients with severe HS that fail to respond to other biologics.

The Effectiveness of Guselkumab in Patients With Hidradenitis Suppurativa Under Clinical Practice Conditions: A Spanish Multicentre Retrospective Study

Improvements in Skin and Nail Psoriasis are Positively Correlated across Systemic Psoriasis Therapies

Objective: For clinical scenarios where patients have moderate to severe psoriasis and nail psoriasis, knowing whether skin response is correlated with nail response would provide insight into the relationship between psoriatic skin and nail unit inflammation. The primary objective of this study was to determine if improvement in skin and nail psoriasis across a range of systemic therapies are correlated. Methods: Relevant publications pertaining to systemic therapies approved in the US for psoriasis were identified via PubMed search. Only studies with placebo controls were included. The paired point estimates of the PASI 75 response treatment effect [i.e., the placebo-adjusted PASI 75 response rate] (independent variable) and mean percentage NAPSI improvement for target fingernail treatment effect [also placebo-adjusted] (dependent variable) were calculated for each therapy. Simple linear regression analysis weighted by the standard errors for the independent and dependent variables was performed. Results: Ten paired treatment effects for 4 systemic therapies (apremilast, adalimumab, etanercept, and guselkumab) were obtained. Guselkumab and adalimumab were associated with the greatest nail improvement, and guselkumab was associated with the greatest skin response rate. PASI 75 response rate and mean percentage improvement target fingernail NAPSI were positively correlated (p=0.03), with an R2 value of 0.48. Conclusions: There is significant positive correlation across different therapies between the magnitude of improvement in psoriatic skin and nail disease among patients with moderate-severe psoriasis and clinically significant nail disease.

Statins and psoriasis: Position statement by the Psoriasis Task Force of the European Academy of Dermatology and Venerology.

Psoriasis is associated with an increased mortality risk, with cardiovascular disease being the leading excess cause (in a dose-response manner with psoriasis severity). Statins have demonstrated a reduction in all-cause mortality with no excess of adverse events among the general population. The underuse of interventions in cardiovascular prevention, such as statins, for patients with psoriasis may be the result of an insufficient evaluation. To provide the dermatologist with a tool for systematizing the treatment of dyslipidemia in psoriasis, which generally escapes the scope of dermatological practice, and to facilitate decision-making about the referral and treatment of patients. The Psoriasis Task Force of the European Academy of Dermatology and Venereology performed this two-phase study to achieve a consensus and create recommendations on the use of statin therapy in patients with psoriasis. The first phase included a systematic review to identify a list of outline concepts and recommendations according to guidelines. The second phase consisted in a two-round Delphi study to evaluate those recommendations not literally taken from guidelines. A list of 47 concepts and recommendations to be followed by dermatologists involved in the treatment of patients with moderate-severe psoriasis was created. It included six main concepts about cardiovascular risk and psoriasis, six items related with the role of low-density lipoprotein cholesterol (LDL-c) and the benefits of statin treatment in psoriasis patients, eight recommendations about how cardiovascular risk should be assessed, three on the role of non-invasive cardiovascular imaging, three on LDL-c thresholds, eight key points related to statin prescription, 10 on statin treatment follow-up and three on patient referral to another specialist. The application of this position statement (close final list of concepts and recommendations) will help dermatologists to manage dyslipidemia and help psoriasis patients to reduce their cardiovascular risk.
