Effectiveness of cyclosporine A in patients with moderate to severe plaque psoriasis in a real-life clinical setting in Italy: the TRANSITION study.

BACKGROUND: Cyclosporine A (CsA) is one of the systemic therapeutic options for moderate-to-severe psoriasis, based on its efficacy and rapidity of action. The current study investigated the response to CsA in patients with moderate-to-severe plaque psoriasis. MATERIALS AND METHODS: TRANSITION was an observational, cross-sectional, multicentre study which evaluated the proportion of partial- and suboptimal-responders among patients with moderate-to-severe plaque psoriasis treated with continuous CsA for ≥12 weeks. Patients demonstrating a Psoriasis Area and Severity Index (PASI) response of ≥90, ≥75 and <90, ≥50 and <75 and <50 were defined as responders, suboptimal-responders, partial-responders, and non-responders, respectively. RESULTS: A total of 196 patients (mean age, 46.6 years; 62.8% males) from 14 sites in Italy were evaluated. At the study visit, the mean (SD) PASI score was 4.2(5.5) compared with 15.3(7.1) prior to the last CsA cycle. For response categories, 39.8%, 22.4%, 16.8%, and 20.9% of patients were responders, suboptimal-responders, partial-responders, and non-responders to CsA treatment. Overall, 28.6% of patients permanently discontinued treatment with CsA (lack of efficacy [10.2%], poor tolerability and voluntary discontinuation [3.6% each], and other [11.7%]). CONCLUSION: Patients were only partially satisfied with CsA treatment, reporting measurable impact on quality of life. Only 40% patients showed a satisfactory response to CsA.

Inside-out and outside-in organotypic normal human skin culture: JAK-STAT pathway is activated after pro-inflammatory psoriatic cytokine exposure.

The Janus kinases-signal transducers and activators of transcription (JAK-STAT) signalling pathway are a pleiotropic cascade that involves ligands such as cytokines, hormones, and growth factors. Among cytokines, interleukin (IL)-17, IL-22, IL-23, and tumour necrosis factor (TNF)-alpha play a pivotal role in psoriasis. We aimed at investigating in an organotypic experimental model of normal human skin (n = 7 women between 20-40 years old, non-smokers) the early, direct, and specific effects of IL-17, IL-22, IL-23, TNF-alpha and a combination of the four cytokines (Mix) on the JAK-STAT/pathway. The expression of the psoriatic marker keratin (K) 17 was analyzed by immunofluorescence and molecular techniques after exposure to IL-23 or Mix. The Mix elicited a strong K17 up-regulation in keratinocytes at 72 h, reinforcing the hypothesis of a synergistic effect of different cytokines. High levels of JAK1 and STAT3 activation were detected, suggesting the involvement of JAK1/STAT3 pathway in the upregulation of K17. As the present study in an organotypic model of human skin reports a variable expression of JAK-STAT upon different cytokine stimuli and most of the JAK inhibitors for the psoriasis treatment have proven to have a clinical efficacy, these observations have a relevance to better understand the mechanisms of JAK-inhibitors in the skin.

Evidence for a 'window of opportunity' in hidradenitis suppurativa treated with adalimumab: a retrospective, real-life multicentre cohort study.

BACKGROUND: The anti-tumour necrosis factor (TNF)-α adalimumab is the only licenced biologic for moderate-to-severe hidradenitis suppurativa (HS). No predictors of response have been identified so far. OBJECTIVES: To identify clinical parameters predicting response to adalimumab and confirm its efficacy/safety. METHODS: The data of 389 patients with HS treated with adalimumab in 21 Italian centres were reviewed. Sex, age at onset/diagnosis/baseline, body mass index, smoking, phenotype, previous treatments, concomitant antibiotics and 'therapeutic delay', defined as the time from HS onset to adalimumab initiation, were assessed. Response to adalimumab and its impact on quality of life (QoL) were evaluated using the Hidradenitis Suppurativa Clinical Response (HiSCR) and the Dermatology Life Quality Index (DLQI) or the Visual Analogue Scale for pain (VAS pain), respectively. Logistic regression analysis was performed. RESULTS: The therapeutic delay correlated to lack of response to adalimumab at week 16 [odds ratio (OR) 1·92 for therapeutic delay > 10 years; 95% confidence interval (CI) 1·28-2·89; P = 0·0016). HiSCR was achieved in 43·7% and 53·9% patients at week 16 and 52, respectively. Significant reductions in both DLQI and VAS pain were found between week 16 vs. baseline (P < 0·0001 for both) and week 52 vs. baseline (P < 0·0001 for both). Previous immunosuppressants inversely correlated to HiSCR at week 52 (OR = 1·74, 95% CI 1·04-2·91, P = 0·0342). CONCLUSIONS: Inverse correlation between therapeutic delay and clinical response was found, supporting early adalimumab use and providing evidence for a 'window of opportunity' in HS treatment. Adalimumab efficacy and safety were confirmed, along with patients' QoL improvement. Immunosuppressants could negatively influence the response to adalimumab inducing a switch to non-TNF-α-driven pathways.

TNF-α inhibitors biosimilars as first line systemic treatment for moderate-to-severe chronic plaque psoriasis.

INTRODUCTION: Biologics have revolutionized the therapy of moderate-to-severe plaque psoriasis. Despite their greater efficacy over conventional systemic therapies their high cost has represented a burden for health-care systems, which limited their use. The availability of biosimilars at low cost is changing the place in therapy of biologics for psoriasis. AREAS COVERED: The role of TNF- α inhibitors in the management of plaque psoriasis, their efficacy and safety profile are presented. Phase 3 clinical trials and real-life data from the use of TNF- α inhibitor biosimilars in the treatment of plaque psoriasis are also reviewed in detail. Furthermore, arguments in favor of the use of TNF- α inhibitor biosimilars as a first-line therapy in moderate-to-severe plaque psoriasis are discussed. EXPERT OPINION: An increasing amount of data show that biosimilars represent a safe and effective alternative to the originator biologics. In the face of ever-increasing health-care costs, switching to biosimilars and starting naïve patients on the best-value biologic can reduce expenditure for patients and payers while maintaining a high-quality care. Moreover, as the cost of biosimilars is approaching the cost of conventional systemic treatments, TNF-α inhibitors biosimilars may represent a first-line systemic treatment for psoriasis patients because they are effective and safe.

Creation of a severity index for hidradenitis suppurativa that includes a validated quality-of-life measure: the HIDRAscore.

BACKGROUND: Hidradenitis suppurativa (HS) is a chronic, debilitating disease with a considerable effect on patient quality of life. Its clinical severity can be measured using different scoring systems; however, few of them include patient-centred parameters. OBJECTIVE: To create a new scoring system for HS that includes a quality-of-life instrument, the HIDRAdisk. METHODS: This post hoc analysis was carried out within the framework of a multicentre, longitudinal, epidemiologic study conducted over 9 months on quality-of-life aspects of HS. The new severity score was created using as reference a question from the Subject Satisfaction Questionnaire (SSQ) concerning the severity of HS as evaluated by the patient. Associated variables were selected using univariable and multivariable logistic regression models. The discriminant capabilities of the final model and of the final score were evaluated by the area under the receiver operating characteristic curve and the Hosmer-Lemeshow test. RESULTS: The study population included 308 patients with HS of any severity grade. According to the results of the regression models, the variables associated with the reference SSQ measure were number of inflammatory nodules, abscesses and draining fistulas; the HIDRAdisk score; and the number of subumbilical lesions. The HIDRAscore is obtained by the sum of the scores associated with the number of these parameters. Possible scores range from 0 to 10. CONCLUSION: The HIDRAscore is a new scoring system for HS severity which, in addition to the clinical evaluation by the physician, includes a validated patient-reported outcome measure, the HIDRAdisk.

Tuscan consensus on the diagnosis and treatment of hidradenitis suppurativa.

BACKGROUND: A rationalized model of clinical and therapeutic management of hidradenitis suppurativa (HS) should place the patients at the heart of the process, facilitating their access to diagnostic tests and treatments, providing the appropriate care for each grade of disease severity and optimizing the use of healthcare resources, both in economic and human terms. MATERIAL AND METHODS: This paper reports the results of a Consensus of the Tuscany HS working group for a rationalized model of diagnosis and management of HS. RESULTS: The diagnostic and therapeutic protocols, the available technological equipments and the management models, are presented in the light of today's scientific evidence. CONCLUSION: The goal of the Consensus is to bring the issue of HS management to the attention of the Tuscan regional government, in order to create unanimously accepted diagnostic and therapeutic protocols.

HIDRAdisk: validation of an innovative visual tool to assess the burden of hidradenitis suppurativa.

BACKGROUND: Hidradenitis suppurativa (HS) is a chronic, relapsing, inflammatory skin disease characterized by painful inflamed nodules, recurrent abscesses and fistulas located in apocrine gland-bearing body sites. The negative impact of HS on patient's quality of life (QoL) has been reported to be greater than other dermatologic conditions as psoriasis and atopic eczema, and its improvement is an important goal in disease management. Nowadays, there are no specific validated QoL instruments available for HS and generic dermatologic questionnaires are used. OBJECTIVE: The objective of this study was to demonstrate the validity, reliability and responsiveness of HIDRAdisk, a new innovative tool designed for rapid assessment of HS burden and, at the same time, an intuitive graphic visualization of the measurement outcome. METHODS: A multicentre, longitudinal, observational study was conducted to validate the HIDRAdisk compared with other validated questionnaires [Skindex-16, Dermatology Life Quality Index (DLQI), Work Productivity and Activity Impairment-General Health (WPAI:GH)] and to evaluate its correlation with disease severity in Italian patients with any degree of HS severity, as measured by Hurley stage and HS Physician Global Assessment (HS-PGA). RESULTS: A total of 140 patients (59% women; mean age 34.9 ± 11.0 years) were enrolled in 27 dermatologic centres. HIDRAdisk showed a strong correlation with Skindex-16 and DLQI, and a good one with WPAI:GH (correlation coefficient: 0.7568, 0.6651 and 0.5947, respectively) and a statistically significant correlation with both Hurley stage and HS-PGA. Very good internal consistency (Cronbach coefficient >0.80; intraclass correlation coefficient >0.6), with correlation between the 10 items, good test-retest reliability (Spearman correlation coefficient, 0.8331; P < 0.0001) and responsiveness to changes were demonstrated. CONCLUSION: Our study shows that HIDRAdisk, a short and innovative visual HS QoL instrument, has been psychometrically validated in Italian language and it may help improve the management of HS once implemented in routine clinical practice.

Clinical experience with the etanercept biosimilar SB4 in psoriatic patients.

Background After the expiry of the patent of reference etanercept, several biosimilars have been developed, including SB4. Objective To study safety and efficacy of SB4 in psoriatic patients previously treated with etanercept and in the etanercept naive ones. Method Patients affected by moderate to severe psoriasis and/or psoriatic arthritis attending the Psoriasis Center of Florence University, treated with SB4 were enrolled in the study. Patients were divided in two cohorts. Cohort 1 included 32 patients who were switched from previous etanercept, cohort 2 included 12 patients who were naive to etanercept. Results Evaluation of the efficacy of SB4 in cohort 1 patients revealed rates of clinical remission (defined as both PASI and/or DAS28 increase < 10%) of 92% and 64% for psoriasis and psoriatic arthritis respectively. In cohort 2 at week 24 PASI 75 was observed in 75% of patients. Conclusion In our experience switching from originator to SB4 in psoriatic patients seems not to influence efficacy, especially cutaneous manifestations, over a median observational period of 24 weeks.

Elderly psoriatic patients under biological therapies: an Italian experience.

BACKGROUND: The number of elderly patients with psoriasis is steadily increasing in the Western world; nevertheless, they are frequently excluded from biological clinical trials and described as a high-risk group for adverse events. Thus, there is lack of information concerning safety and effectiveness of available treatments for psoriasis in the elderly, particularly about new biological systemic drugs. OBJECTIVE: Our aim was to describe our experience with all biological therapies currently used in the elderly (>65 years) psoriatic patients. METHODS: A retrospective multicentric review of clinical records of all psoriatic patient aged 65 years or older actually receiving biological drugs (etanercept, adalimumab, infliximab, golimumab, certolizumab pegol, ustekinumab or secukinumab) was undertaken. RESULTS: Our study population included 266 elderly psoriatic patients actually receiving any biological therapy (adalimumab 31.2%, ustekinumab 28.9%, etanercept 20.3%, secukinumab 15%, infliximab 3%, golimumab 1% and certolizumab pegol 0.6%). The PASI score at the baseline (week 0) ranged from 4 to 54; mean ± SD, 16.5 ± 7.1, which changed after biological administration to 3.7 ± 8 at week 16, 1.6 ± 2.1 at week 28 and 1.2 ± 2.1 at week 52. Among 266 elderly psoriatic patients, 25 adverse events were reported during the observation period. The most frequent events were infections with 12 (48%) reports, followed by malignancies with four (16%) reports. CONCLUSIONS: To date, our study represents the widest experience on the use of biological drugs in elderly psoriatic patients. We found that all biologics for psoriasis showed a great efficacy also in elderly people, and the rate and the type of adverse effects were similar to the younger patients. In conclusion, the age alone should not limit our therapeutic options. Further observational study using multiple data sources is needed to evaluate long-term effectiveness and safety for elderly psoriatic patients.

The role of the dermatologist in Raynaud's phenomenon: a clinical challenge.

Raynaud's phenomenon (RP) is a functional vascular disorder involving extremities. In his practice, the dermatologist may frequently encounter RP which affects mainly women and is categorized into a primary benign form and a secondary form associated with different diseases (infections, drugs, autoimmune and vascular conditions, haematologic, rheumatologic and endocrinologic disorders). Still today, the differential diagnosis is a clinical challenge. Therefore, a careful history and a physical examination, together with laboratory tests and nailfold capillaroscopy, is mandatory. RP is generally benign, but a scheduled follow-up for primary RP patients should be established, due to risk of evolution to secondary RP. A combination of conservative measures and medications can help in the management of RP. The importance of avoiding all potential physical, chemical and emotional triggers, as well as quitting smoking, should be strongly suggested to the patient. As first-line treatment, dihydropyridine calcium channel blockers should be used. If this approach is not sufficient, prostacyclin derivatives, phosphodiesterases inhibitors and endothelin receptor antagonists can be considered as second-line treatment. In cases of acute ischaemia, nifedipine and intravenous prostanoids are helpful. In refractory cases, botulinum injections have shown a significant benefit. The approach to the RP patients requires therefore a coordinated care of specialists together with the primary care physician.
