Effectiveness of guselkumab in patients with facial and/or genital psoriasis: Interim analysis results at Week 12 from the GULLIVER study.

BACKGROUND: Facial (FP) and genital psoriasis (GP) significantly affect patients' quality of life. Despite the advances in treatments, limited data on efficacy and safety are available on these difficult-to-treat areas. Guselkumab is an interleukin (IL)-23 inhibitor which has been proven effective in treating patients with moderate-to-severe plaque psoriasis. OBJECTIVES: The aim of this interim analysis was to report the efficacy and safety of guselkumab in the treatment of patients with FP and/or GP. MATERIALS AND METHODS: GULLIVER is a 52-week Italian observational study to evaluate the effectiveness and safety of guselkumab in a real-life setting in patients with FP and/or GP. Adult patients with facial and/or genital moderate-to-severe psoriasis (sPGA score ≥ 3) were included. The primary endpoint of this analysis was the percentage of patients achieving a facial or genital sPGA score of 0 (clear) or 1 (almost clear), at Week 12. The change in the score of the facial or genital sPGA components in patients with a score ≥3 for each sPGA component was assessed. PASI score in patients with a baseline PASI above or below 10 was evaluated. RESULTS: Overall, 351 patients were included in the study; 83.3% of FP and 76.5% of GP patients achieved the primary endpoint. Similar response rates were observed for the facial or genital sPGA components in patients with a baseline facial or genital sPGA score ≥3 in each component. Among patients with a baseline PASI score >10, mean PASI score improved from 19.0 (SD 8.3) to 2.2 (SD 4.8). Forty-four AEs were observed in 32 patients; two mild and transient AEs (fatigue and nausea) were considered treatment related. No SAEs were observed. CONCLUSIONS: Guselkumab, showing to be effective and safe in treating FP and GP, may be a valid therapeutic option for patients with psoriasis localized in these difficult-to-treat areas.

Long-term clinical efficacy and safety of ixekizumab for psoriatic patients: a single-center experience.

OBJECTIVE: While clinical trials provide invaluable evidence, real-world data can offer further insight on the efficacy and safety of biologic drugs. This report aims to analyze the long-term efficacy and safety of ixekizumab in real-world clinical practice in our facility. PATIENTS AND METHODS: Patients with a diagnosis of psoriasis and who started treatment with ixekizumab were included in this retrospective study and followed for 156 weeks. The severity of cutaneous manifestations was evaluated using the PASI score at several time points and clinical efficacy was evaluated using PASI 75, -90 and -100 responses. RESULTS: Not only PASI 75, but also PASI 90 and 100 responses showed a favorable outcome after treatment with ixekizumab. Responses at week 12 were sustained through the following three years in the majority of patients. No statistically significant difference was found between bio-naive and bio-switch patients and weight and disease duration had no impact on the efficacy of the drug. Ixekizumab had a favorable safety profile, as we observed no major adverse events. Two cases of eczema were observed and led to drug discontinuation. CONCLUSIONS: This study confirms the efficacy and safety of ixekizumab in real-world clinical practice.

Real-life experience with ixekizumab in plaque psoriasis: a multi-center, retrospective, 3-year study.

BACKGROUND: Confirmatory data on the long-term effectiveness and safety of ixekizumab in psoriatic patients from real-world studies are needed. OBJECTIVES: The primary aim was to evaluate the 3-year drug survival of ixekizumab in the treatment of patients with moderate-to-severe plaque psoriasis, in a multicenter real-world setting. The secondary aim was to assess the influence of predictive factors on the drug survival of ixekizumab. METHODS: A retrospective analysis was performed on a cohort of patients with chronic plaque psoriasis, who received at least one dose of ixekizumab before December 2018. The drug survival analysis was performed and descriptively analyzed using Kaplan-Meier survival curves. Multivariable Cox regression analyses were carried out including variables considered to be of clinical importance. RESULTS: A total of 306 patients were enrolled. The overall drug survival at 12, 24, and 36 months of treatment with ixekizumab was 92.11%, 83.85%, and 80.19%, respectively. A higher probability (HR 2.34) of drug withdrawal was found among patients who had already received an anti-IL-17 agent compared with bio-naive patients (p 0.017). CONCLUSIONS: We found that ixekizumab is a biological agent characterized by long-term effectiveness, not influenced by several clinical factors and associated with a good safety profile.

Psoriasis patients' characteristics associated with high PASI response to tildrakizumab: an international dual center study.

OBJECTIVE: Heterogeneous real-world evidence can complement the more strictly regulated clinical trial data. A benefit of this is the wide range of backgrounds, comorbidities and characteristics that can give additional insights into treatments. Observational, retrospective studies can help to fill in the mosaic that makes up a treatments landscape. Tildrakizumab, an interleukin 23p19 inhibitor, is approved for the treatment of plaque psoriasis and has been shown to be a safe and efficacious therapy in clinical trials and emerging real-world evidence. We aimed at confirming the efficacy of tildrakizumab in patients with plaque psoriasis in a dual center setting and identifying patients' characteristics leading to better treatment response. PATIENTS AND METHODS: Patients with moderate to severe plaque psoriasis, eligible for systemic biological treatment, and treated with tildrakizumab were included in the study and the routine clinical parameters - Psoriasis Area and Severity Index (PASI), Dermatology Life Quality Index (DLQI), and safety - were retrospectively analyzed. RESULTS: The combined cohorts included 89 patients, of which 64% were naïve to biologic therapies. At the time of analysis efficacy assessment was available for 39 patients after 12 months of treatment, 73 patients after 36 weeks, 79 patients after 16 weeks and 82 patients after 4 weeks. PASI and DLQI decreased significantly over time, with 52/73 (71.2%) patients achieving PASI 100 after 36 weeks. No severe side-effects were recorded in association with tildrakizumab. CONCLUSIONS: We confirmed the safety and efficacy of tildrakizumab in a real-world clinical setting. A higher proportion of patients naïve to biologics achieved a greater PASI response than patients who had previously been treated with biologics. The same was true for older patients and patients with a shorter history of disease.

Certolizumab for the treatment of psoriasis and psoriatic arthritis: a real-world multicentre Italian study.

BACKGROUND: Certolizumab, a pegylated tumour necrosis factor-α inhibitor, reduced disease activity in randomized trials of patients with psoriasis and psoriatic arthritis. Real-life data are missing. OBJECTIVE: To confirm the effectiveness and safety of certolizumab in patients with psoriasis and psoriatic arthritis in routine clinical practice. METHODS: In this retrospective study involving 11 Italian sites, patients with psoriasis and psoriatic arthritis received subcutaneous certolizumab (400 mg loading dose at 0, 2 and 4 weeks, followed by 200 mg every 2 weeks) for up to 52 weeks. Primary outcomes included mean change from baseline in Psoriasis Area and Severity Index (PASI) and modified Nail Psoriasis Severity Index (mNAPSI) scores, and the proportion of patients achieving a 75%, 90% or 100% reduction in PASI score. Other endpoints included Disease Activity Score computed on 44 joints correlated with the erythrocyte sedimentation rate during the first hour (DAS44-ESR), Tender Joint Count (TJC), Swollen Joint Count (SJC), pain [visual analogue scale (VAS) score], inflammatory markers and quality of life (QOL). RESULTS: In the study were enrolled 153 patients (mean age: 55 years). Certolizumab reduced the mean PASI score from baseline by 4.45, 6.30 and 7.58 at weeks 12, 24 and 52, respectively (P < 0.001 for all). At weeks 24 and 52, 69.6% and 83.3% of patients had a PASI score ≤3. DAS44-ESR, TJC, SJC and mNAPSI scores, and pain VAS were also all significantly improved from baseline at each time point. C-reactive protein levels decreased during treatment, being significant at week 24. On multivariate analysis, psoriasis duration, baseline PASI, mNAPSI and pain VAS scores were found to be predictive of the improvement in PASI score at week 12. CONCLUSION: Certolizumab displayed also in the real-life encouraging results in both psoriasis and psoriatic arthritis patients.

Simulation of urban boundary and canopy layer flows in port areas induced by different marine boundary layer inflow conditions.

Computational fluid dynamics (CFD) simulations and wind-tunnel (WT) tests can be considered as boundary-value problems, where the inlet boundary condition, which is usually obtained inferring inlet mean wind profiles from on-site measurements or other type of experimental data, represents the large-scale atmospheric forcing exerted at the outer limit of the urban model. It is not clear, however, to which extent the choice of different inflow wind speed profiles may affect WT and CFD results in the urban environment. In the present study, this aspect is investigated through the comparison of the wind flow fields simulated numerically and tested experimentally in an atmospheric boundary layer wind tunnel (ABLWT) within a district of Livorno city, Italy, called "Quartiere La Venezia". Three different shapes of inflow profiles were tested using the CFD technique and the results were compared with each other: one is based on the approach-flow profiles measured upstream of the urban model in the WT test section (WT profile) and two are based on anemometric data corresponding to the approach-flow profile measured by means of a LiDAR wind profiler (LiDAR profile 1 and 2). The analysis showed that using different wind speed profiles does not affect significantly the results in the urban canopy layer (UCL), where correlations of 95% and 98% were found between the LiDAR profile 1 and 2 data and the WT profile data (at z = 0.02 m above the bottom), respectively. Conversely, the different inflow profiles strongly affected the results above the UCL. This means that the local-scale effects induced on the wind field in the UCL by the urban texture are dominated mainly by the larger-scale forcing, as within the canopy the flow remains topologically invariant despite the different inflow conditions.

Generalized annular granuloma associated with crowned dens syndrome, which resolved with colchicine treatment.

Granuloma annulare (GA) is a chronic, benign, and usually self-limiting cutaneous inflammatory disease, typically characterized by small, localized, skin-coloured papules that are usually asymptomatic or mildly pruriginous. Its aetiopathogenesis is still unknown and treatments are rarely effective. Generally, 50-70% of localized GA cases are self-limiting and show spontaneous resolution after 1-2 years, whereas disseminated GA is less likely to disappear without treatment. Treatment of generalized GA is usually based on single case reports, and only a few studies involving large case series have been published. We present the case of a patient affected by generalized GA, which resolved after colchicine treatment used for concomitant crowned dens syndrome due to calcium pyrophosphate deposition disease (CPPD). Colchicine may have worked by a direct action on GA or, alternatively, by controlling CPPD, as a possible trigger. As the low-dosage colchicine treatment was well tolerated by our patient, this could be easily used in the management of GA. However, further studies are needed to confirm the action of colchicine on GA.

Vasculitis associated with connective tissue diseases.

Vasculitis in connective tissue disease (CTD) is quite rare, it is reported in approximately 10% of patients with CTD; systemic lupus erythematosus (SLE) shows the highest association rate. Vessels of any size may be involved, but mainly small vessels vasculitis is reported. At present the classification of these vasculitis is unsatisfactory. According to the 2012 revised International Chapel Hill Consensus Conference, vasculitides secondary to CTD are a well identified entity and are classified under the category of "vasculitis associated with systemic disease". However only lupus vasculitis and rheumatoid vasculitis are explicitly listed, while the remaining are generically included under the heading "others". Petechiae, purpura, gangrene and ulcers are the most frequent cutaneous manifestations that should investigated in order to rule out potentially dangerous systemic involvement, especially if cryoglobulinemic or necrotizing vasculitis are suspected. This review will focus on the cutaneous involvement in CTD associated vasculitis.

Bilateral Warthin tumor in psoriatic patients in therapy with multiple immunosuppressive therapy.

Anti-TNFα drugs have strongly changed the way in which we deal with moderate and severe psoriasis. However, it is debatable whether biological drugs could increase the risk of developing cancer. The correlation between anti-TNFα drugs and lymphomas is well-known and is reported in all the technical details of biologic drugs. However, the association between anti-TNFα agents and solid tumors is still controversial. The authors report a case of bilateral salivary gland tumor in a psoriatic patient treated with several immunosuppressive therapies including anti-TNFα inhibitors.
