Rapid response on facial psoriasis to bimekizumab: case series.

Psoriasis is a chronic inflammatory disease that can affect any part of the body but, when it appears in certain areas, like the face, it can have a very significant psychological impact. Biologics, in particular IL-17 and IL-23 drug inhibitors, have shown relevant clinical efficacy in the management of psoriatic lesions in difficult-to-treat areas. In post hoc analysis of phase III trials in plaque psoriasis, bimekizumab has shown safety and complete clearance of high-impact areas. However, these studies did not focus on the effect of bimekizumab on facial lesions. Therefore, this case series represents the first clinical real-life experience of rapid and successful management of facial psoriasis with bimekizumab in six patients.

Therapeutic Potential of Spesolimab-Sbzo in the Management of Generalized Pustular Psoriasis Flares in Adults: Evidence to Date.

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.

Interleukin-17A-Correlated Myocarditis in Patients with Psoriasis: Cardiac Recovery following Secukinumab Administration.

(1) Background: Psoriasis (PS) is a common immune-mediated disease of the skin with possible extension to joints, aorta and eye. Myocardial inflammation has rarely been suggested. (2) Aims: Report of PS-related myocarditis. (3) Methods and Results: One hundred consecutive patients with PS were screened for cardiac involvement. Among them, five male patients (aged 56 ± 9.5 years) with a moderate-severe form of PS showed dilated cardiomyopathy (LVEF < 35%) with normal coronary arteries and valves. They underwent a left-ventricular endomyocardial biopsy for evaluation of myocardial substrate. Endomyocardial samples were processed for histology and immunohistochemistry, including myocardial expression of Toll-Like Receptor 4 (TLR4) and interleukin-17A (IL-17A), which play a major role in PS pathogenesis. Real-time PCRs were carried out for cardiotropic viruses, and Western blot analysis was conducted for myocardial expression of IL-17A. Patients' sera were tested for anti-heart autoantibodies. Active lymphocytic myocarditis was revealed in all five patients, characterized by an absence of viral genomes with PCR, positive anti-heart autoantibodies, overexpression of TLR-4 and enhancement of IL-17-A during western blot analysis, showing a 2.48-fold increase in psoriatic myocarditis compared with no psoriatic myocarditis and a six-fold increase compared to myocardial controls. Treatment included combination of prednisone (1 mg/kg daily for 4 weeks, tapered to 0.33 mg/kg) and azathioprine (2 mg/kg, daily) in 3 pts or secukinumab (SK, 150 mg/weekly for 4 weeks followed by 150 mg/monthly) in 2 pts for 6 months. LVEDD and LVEF improved in the first 3 pts (-14% and + 118%, respectively), while they completely recovered (LVEF > 50%) in the last 2 pts on SK. (4) Conclusions: IL-17A-related myocarditis can occur in up to 5% of patients with PS. It manifests as progressive dilated cardiomyopathy. It may completely recover following SK administration.

Impact of Functional Polymorphisms on Drug Survival of Biological Therapies in Patients with Moderate-to-Severe Psoriasis.

Biological therapies (BTs) indicated for psoriasis are highly effective; however, not all patients obtain good results, and loss of effectiveness is the main reason for switching. Genetic factors may be involved. The objective of this study was to evaluate the influence of single-nucleotide polymorphisms (SNPs) on the drug survival of tumor necrosis factor inhibitors (anti-TNF) medications and ustekinumab (UTK) in patients diagnosed with moderate-to-severe psoriasis. We conducted an ambispective observational cohort study that included 379 lines of treatment with anti-TNF (n = 247) and UTK (132) in 206 white patients from southern Spain and Italy. The genotyping of the 29 functional SNPs was carried out using real-time polymerase chain reaction (PCR) with TaqMan probes. Drug survival was evaluated with Cox regression and Kaplan-Meier curves. The multivariate analysis showed that the HLA-C rs12191877-T (hazard ratio [HR] = 0.560; 95% CI = 0.40-0.78; p = 0.0006) and TNF-1031 (rs1799964-C) (HR = 0.707; 95% CI = 0.50-0.99; p = 0.048) polymorphisms are associated with anti-TNF drug survival, while TLR5 rs5744174-G (HR = 0.589; 95% CI = 0.37-0.92; p = 0.02), CD84 rs6427528-GG (HR = 0.557; 95% CI = 0.35-0.88; p = 0.013) and PDE3A rs11045392-T together with SLCO1C1 rs3794271-T (HR = 0.508; 95% CI = 0.32-0.79; p = 0.002) are related to UTK survival. The limitations are the sample size and the clustering of anti-TNF drugs; we used a homogeneous cohort of patients from 2 hospitals only. In conclusion, SNPs in the HLA-C, TNF, TLR5, CD84, PDE3A, and SLCO1C1 genes may be useful as biomarkers of drug survival of BTs indicated for psoriasis, making it possible to implement personalized medicine that will reduce financial healthcare costs, facilitate medical decision-making and improve patient quality of life. However, further pharmacogenetic studies need to be conducted to confirm these associations.

Brodalumab for the Treatment of Moderate-to-Severe Psoriasis: An Expert Delphi Consensus Statement.

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. These statements aid dermatologists in the management of patients with moderate-to-severe psoriasis.

Understanding Barriers Impacting upon Patient Wellbeing: A Nationwide Italian Survey and Expert Opinion of Dermatologists Treating Patients with Moderate-to-Severe Psoriasis.

A nationwide cross-sectional online survey was administered to dermatologists managing patients with moderate-to-severe plaque psoriasis across Italy to obtain real-world dermatologists' perspectives on the impact of psoriasis and its treatment on patients' daily lives and quality of life (QoL). A total of 91 dermatologists (aged 39.1 ± 11.2 years) completed a 31-question survey and workshop sessions were undertaken in order to identify the best management approach to achieve patient wellbeing. Social (4.2 ± 0.1), physical (4.26 ± 0.2) and mental components (4.1 ± 0.3) were rated by dermatologists as contributing to patient wellbeing to similar extents. While a high proportion (85.4%; rating of 4.3 out of 5) of dermatologists felt that they considered the QoL of patients, a lower proportion (69.6%; rating of 3.7 out of 5) felt that patients were satisfied in this regard. The psoriasis area and severity index and body surface area were the instruments most frequently used to assess the physical domain, while interviews/questions and the dermatology life quality index were used to assess social and mental domains, with only 60% of dermatologists following up on these aspects. The importance of investigating the presence of comorbidities was recognized but not always carried out by many dermatologists, (>70%), particularly for obesity and anxiety/depression. This survey identified key components contributing to barriers impacting on the QoL of patients with moderate-to-severe psoriasis from the perspective of the dermatologist.

A Possible Link between Gut Microbiome Composition and Cardiovascular Comorbidities in Psoriatic Patients.

Cardiovascular disease (CVD) is one of the most common comorbidities that may affect psoriatic patients. Several exogenous and endogenous factors are involved in the etiology and progression of both psoriasis and CVD. A potential genetic link between the two diseases has emerged; however, some gaps remain in the understanding of the CVD prevalence in psoriatic patients. Recently, the role of the gut microbiome dysbiosis was documented in the development and maintenance of both diseases. To investigate whether gut microbiome dysbiosis might influence the occurrence of CVD in psoriatic patients, 16S rRNA gene sequencing was performed to characterize the gut microbiome of 28 psoriatic patients, including 17 patients with and 11 without CVD. The comparison of the gut microbiome composition between patients with and without CVD showed a higher prevalence of Barnesiellaceae and Phascolarctobacterium in patients with CVD. Among patients with CVD, those undergoing biologic therapy had lower abundance levels of Barnesiellaceae, comparable to those found in patients without CVD. Overall, these findings suggest that the co-occurrence of psoriasis and CVD might be linked to gut microbiome dysbiosis and that therapeutic strategies could help to restore the intestinal symbiosis, potentially improving the clinical management of psoriasis and its associated comorbidities.

Sharing Patient and Clinician Experiences of Moderate-to-Severe Psoriasis: A Nationwide Italian Survey and Expert Opinion to Explore Barriers Impacting upon Patient Wellbeing.

A nationwide survey was conducted in adult patients with psoriasis (PsO) across Italy to obtain their real-world perspective of the impact of PsO on their wellbeing. Patients completed a 26-question survey (based on the patient benefit index; PBI, The Dermatology Life Quality Index; DLQI and the World Health Organization-five; WHO-5 wellbeing index) and workshop discussion sessions were undertaken by dermatologists to interpret results from the survey. 392 patients with PsO completed the survey. Analysis of results was restricted to patients who had moderate-to-severe plaque psoriasis (assessed by patients; n = 252; 64.3%). Dermatologists (n = 32) completed one question from the survey related to wellbeing and rated social, physical and mental domains as contributing to a similar extent, with comparable scores also observed by patients. For treatment, biologics yielded higher scores on average, whereas little difference was observed between topical and conventional systemic treatments. Only 23.8% of patients felt that their dermatologist was taking into consideration their wellbeing and 32.6% of the patients considered their therapy as inadequate in improving signs and symptoms of the disease. This survey identified key factors contributing to barriers impacting on patient wellbeing. Simple, but comprehensive questionnaires can provide important insight to patients' needs that may significantly increase clinician awareness during visits leading to tailored treatment.

Assessing the Beneficial Impact of a Patient Support Program in Secukinumab-Treated Patients with Psoriasis in Italy.

PURPOSE: For patients with psoriasis, treatment adherence and persistence are fundamental if therapeutic goals are to be met. Patient Support Programs (PSPs) may be used as a support tool to assist patients and health care professionals optimize treatment and improve disease management. PATIENTS AND METHODS: In Italy, the PSP PSOLife CARE, which began on the 9th of February 2017 and is ongoing, aimed to support patients with psoriasis under therapy with secukinumab (Cosentyx®). A team of medical professionals including Dermatologists, Psychologists, Nutritionists, and field Nurses provided outpatient treatment as well as remote support via phone calls. Patients had a standard duration in the Program of 6 months. This report analyzes the data of patients who benefited from the Program from February 2017 to August 2020, for a total observation of 42 months. RESULTS: We provide here a descriptive report on the benefits of participation in the PSOLife CARE Program for patients with psoriasis and medical professionals involved in their care. Throughout their time in the PSOLife CARE Program, patient satisfaction remained consistently high with sustained improvements observed in all aspects of quality of life (ie emotional, social, physical, and economic). Despite exiting from the Program, most patients continued to adhere to secukinumab. Medical professionals also reported positive outcomes on their interactions with patients, with more than half of those surveyed rating the overall quality of the Program as "Outstanding". CONCLUSION: By supporting treatment adherence, the PSOLife CARE Program may have empowered patients to better manage their psoriasis, increasing their satisfaction with treatment and quality of life.

Gut microbiome profile in psoriatic patients treated and untreated with biologic therapy.

There are increasing data about the role of the gut microbiome in various autoimmune diseases, including psoriasis, a chronic inflammatory and immune-mediated disease. Current treatment strategies in psoriasis include immunomodulating biologic agents. A variable response to this type of therapy has been reported in psoriatic patients. A possible effect of biologic therapy on the gut microbiome composition has been suggested, but data are still limited. The aim of this study was to compare the gut microbiome composition between psoriatic patients treated and untreated with biologic drugs in order to identify differences which may highlight the potential impact of the treatment on the gut microbiome. 16S rRNA sequencing and bioinformatic analyses were performed on the fecal samples of 30 psoriatic patients with similar clinicopathological features, 10 of whom were undergoing biologic therapy and 20 not receiving systemic therapy. Alpha and beta diversity significantly differed between the two groups of patients. A reduced bacterial biodiversity in the group of treated patients compared with the group of untreated patients was observed. Differential relative abundances of key gut microbial communities, including Akkermansia muciniphila and Bacteroides plebeius, were identified between the two groups of patients. This study showed that biologic therapy may have an impact on the composition of the gut microbiome of psoriatic patients. Gut microbiome composition could be used as an indicator of response to therapy and the modulation of the microbial composition could help to restore the intestinal symbiosis in psoriatic patients.

Optimizing Secukinumab Treatment in Psoriasis with Concomitant Methotrexate Administration: Minireview and A Case Report.

The introduction of biologic drugs for the treatment of moderate-to-severe psoriasis resulted in a significant improvement in patients' health. Moreover, treatment regimens in psoriatic patients should be tailored to meet specific needs based on disease severity, impact on quality of life, response to previous therapies and presence of comorbidities. Combination therapy of biologic agents with conventional systemic drugs has been proposed to optimize psoriasis treatment outcomes in unresponsive or partial responsive severe psoriatic patients. We report the case of a patient with a long-standing recalcitrant plaque psoriasis and psoriatic arthritis who was administered secukinumab combined with methotrexate. The patient had previously been treated with several topical and systemic therapies associated with loss of efficacy or adverse event occurrence. Approximately 24 weeks after starting the combined regimen, significant clearance of psoriasis and reduction of arthritis ensued, with no drug side effects.

MiRNAs as Potential Prognostic Biomarkers for Metastasis in Thin and Thick Primary Cutaneous Melanomas.

BACKGROUND/AIM: The identification of novel prognostic biomarkers for melanoma metastasis is essential to improve patient outcomes. To this aim, we characterized miRNA expression profiles in relation to metastasis in melanoma and correlated miRNAs expression with clinical-pathological factors. MATERIALS AND METHODS: MiR-145-5p, miR-150-5p, miR-182-5p, miR-203-3p, miR-205-5p and miR-211-5p expression levels were analyzed in primary cutaneous melanomas, including thin and thick melanomas, and in melanoma metastases by quantitative Real-Time PCR. RESULTS: A significantly lower miR-205-5p expression was found in metastases compared to primary melanomas. Furthermore, a progressive down-regulation of miR-205-5p expression was observed from loco-regional to distant metastasis. Significantly lower miR-145-5p and miR-203-3p expression levels were found in cases with Breslow thickness >1 mm, high Clark level, ulceration and mitotic rate ≥1/mm2 Conclusion: Our findings point to miR-205-5p as potential biomarker of distant metastases and to miR-145-5p and miR-203-3p as markers of aggressiveness in melanoma.

Case Report: Cetuximab use in advanced cutaneous squamous cell carcinoma resistant to chemotherapy.

We present the case of a 60-year-old man with unresectable cutaneous squamous cell carcinoma (cSCC) of the sternal area, which was not amenable to radiation therapy. The treatment history of this patient is remarkable as the disease had progressed through all lines of conventional therapy established in the literature. We decided to initiate treatment with epidermal growth factor receptor (EGFR) inhibitor cetuximab and we reassessed the patient after 12 weeks with a whole-body CT scan, documenting stability in the size and radiologic features of the disease. Cetuximab, like all current treatments for advanced cSCC, is administered off-label and proved effective in preventing further progression of disease in our patient.

PIK3CA c.3140A>G mutation in a patient with suspected Proteus Syndrome: a case report.

We present a patient with suspected Proteus Syndrome, an overgrowth disorder associated with AKT1c.49G>A mutation. NGS analysis detected PIK3CAc.3140A>G mutation in the patient's affected tissue allowing for PROS (PIK3CA-related overgrowth spectrum) diagnosis. The overlapping clinical features in overgrowth disorders highlight the importance of molecular testing for a correct diagnosis.

Psoriasis, vitamin D and the importance of the cutaneous barrier's integrity: An update.

Psoriasis is a common, inflammatory, chronic, relapsing skin disease. Despite several hypotheses having been postulated to explain the pathogenesis of this disorder, nowadays it is considered as a T-cell-mediated disease; in this context an important role is played by vitamin D. The role of this micronutrient is important for many reasons: it is able to modulate the immune system; it is implicated in keratinocyte turnover; and it is involved in the integrity of the cutaneous barrier. In psoriasis, this molecule plays an important role due to its ability in the modulation of innate and adaptive immunity and by its antiproliferative and pro-differentiative effects on keratinocytes. Alteration of the metabolism of vitamin D may alter the cutaneous barrier integrity and favor an infective and inflammatory condition. The importance of vitamin D in the pathogenesis of psoriasis is not a mere mental exercise but may open further perspectives in the treatment of this disorder just preventing alterations of immune homeostasis, modulating the proliferation of keratinocyte, regulating the microbial flora and the response of the host to infective diseases.

Safety and efficacy of anti-tumor necrosis factors α in patients with psoriasis and chronic hepatitis C.

Up to date, in literature, it is still debated the role of anti-tumor necrosis factors (TNF)-α treatments in hepatitis C virus (HCV) patients. TNF-α performs a lot of functions, it is an important pro-inflammatory cytokine and it is involved in the host's immunity. Since TNF-α is implicated in the apoptotic signaling pathway of hepatocytes infected by HCV, anti TNF-α therapy may increase the risk of viral replication or their reactivation. However the treatment of anti TNF-α could have a healthful role because TNF-α appears to be engaged in the pathogenesis of liver fibrosis, inducing apoptotic pathways. We describe the case of a patient with plaque-type psoriasis and concomitant chronic HCV, who was treated successfully with anti-TNF agents simultaneously to cyclosporine without sign of reactivation of HCV and increase of liver enzymes. Our personal experience shows that anti-TNF-α agents are not only effective but also safe. Furthermore the combination therapy of cyclosporine and anti-TNF-α appears to be well-tolerated and able to reduce the amount of liver enzymes as well as HCV-viral-load. However systematic, large-scale studies with long follow-ups will be needed to confirm our results, in association with close liver function monitoring.

Clinicopathological features, vitamin D serological levels and prognosis in cutaneous melanoma of shield-sites: an update.

Intermittent sun exposure and sunburns are strongly related to the development of melanoma (MM); however, MM can also arise in non-sun exposed areas, where other biological pathways may cause the disease, with different outcomes. At the same time, evidences of serum levels of vitamin D in melanoma patients according to sun-exposed or not-sun-exposed areas are still lacking, especially if compared with the percentage of BRAF mutation. We performed a retrospective analysis with patients registered in our electronic database and an observational study in patients with a recent diagnosis of MM. Performing Kaplan-Meier product and log-rank test, median disease-free survival was 78 months in non-shield-sites (NST-MM) patients and 20.5 months in shield-sites (ST-MM) patients (p < 0.0001); also in the long term, a better behavior was observed for NST-MM (80 vs. 42 months; p < 0.0001). Among 87 melanoma patients with a recent history of MM (≤30 days), we found that ST-MM patients showed lower values of vitamin D compared with NST-MM patients. Regarding BRAF status, a BRAF mutation was present in 13 % of ST-MM and in 41 % of NST-MM. Performing Mc-Nemar test, we found a statistical significant correlation between low serum levels of vitamin D in ST-MM and low percentage of BRAF mutation (p = 0.03), as well as between serum levels of vitamin D and high percentage of BRAF mutation in NST-MM (p < 0.001). All these aspects confirm that in ST-MM, other pathways play pivotal points, if compared with NST-MM.

Thin melanoma and late recurrences: it is never too thin and never too late.

In the absence of risk factors, thin melanomas (TM) present a long-term survival; however, recurrences may occur. We describe the predictive clinicopathological features of patients with metastatic TM. Kaplan-Meier product was performed for the survival analysis, while Cox proportional hazards regression was used to evaluate the effect of the clinicopathological features on disease-free survival (DFS) and overall survival (OS). Median DFS of the entire cohort was 26 months and three patients developed late metastases. Nine patients developed extra-nodal metastases as first recurrence, while cases of positive sentinel lymph node biopsy (SLNB) were not found. DFS and OS varied according to the clinicopathological features, but only ulceration remained the main statistical significance value. According to our results, a hypothetical use of SLNB in TM without other risk factors is not currently feasible. No consensus exists as to which patients with TM are at risk for metastases or late recurrences.

Mutational profiling in melanocytic tumors: multiple somatic mutations and clinical implications.

In this study, we analyzed multiple somatic mutations in 10 genes relevant in melanoma tumorigenesis and targeted therapies. Overall, 45% of the tumors showed mutations and, in particular, 33% had multiple mutations. Based on our results, we conclude that the assessment of mutation status of multiple genes, including CDKN2A, could provide a genetic profile that can be useful as a prognostic and therapeutic marker in melanocytic tumors.
