Vitiligo Treated with Combined Piperine-Based Topical Treatment and Narrowband Ultraviolet B Therapy: Follow-Up with Reflectance Confocal Microscopy.

BACKGROUND: Reflectance confocal microscopy (RCM) has a defined in vivo morphology of vitiligo and re-pigmentation. Combination therapies seem more effective than monotherapies. OBJECTIVE: We aim to describe the clinical and RCM features of re-pigmentation with combined narrowband ultraviolet B (NB-UVB) and piperine-based topical treatment in localized vitiligo. METHODS: Eight patients enrolled at a single center received combined treatment: topical treatment was applied twice daily + NB-UVB twice weekly for 2 × 2-month periods. Clinical changes were analyzed by the Vitiligo Noticeability Scale (VNS) and percentage of re-pigmentation. The evaluator agreement was assessed. Predefined RCM features had the presence/absence of (i) blood vessels, (ii) dendritic cells, and the quantity of (i) an irregular honeycombed pattern and (ii) non-pigmented papillae. Clinical and RCM monitoring was performed at the baseline, 2, 3, 5, and 7 months. RESULTS: Macules were "slightly less noticeable" with 25-50% re-pigmentation. Irregular honeycomb patterns and non-pigmented papillae were significantly less frequently observed, and in less extended areas (T1 vs. T2, p = 0.039; T0 vs. T1, p = 0.005 and T2 vs. T4, p = 0.033). Dendritic cells and blood vessels improved, with significant changes in blood vessels (T1 vs. T2, p = 0.005 and T3 vs. T4, p = 0.008). CONCLUSIONS: RCM confirms the morphological changes induced by combined treatment for localized vitiligo.

Long-Term Drug Survival and Effectiveness of Secukinumab in Patients with Moderate to Severe Chronic Plaque Psoriasis: 42-Month Results from the SUPREME 2.0 Study.

Purpose: SUPREME, a phase IIIb study conducted in Italy, demonstrated safety and high efficacy of secukinumab for up to 72 weeks in patients with moderate-to-severe plaque-type psoriasis. SUPREME 2.0 study aimed to provide real-world data on the long-term drug survival and effectiveness of secukinumab beyond 72 weeks. Patients and Methods: SUPREME 2.0 is a retrospective observational chart review study conducted in patients previously enrolled in SUPREME study. After the end of the SUPREME study, eligible patients continued treatment as per clinical practice, and their effectiveness and drug survival data were retrieved from medical charts. Results: Of the 415 patients enrolled in the SUPREME study, 297 were included in SUPREME 2.0; of which, 210 (70.7%) continued secukinumab treatment throughout the 42-month observation period. Patients in the biologic-naïve cohort had higher drug survival than those in the biologic-experienced cohort (74.9% vs 61.7%), while HLA-Cw6-positive and HLA-Cw6-negative patients showed similar drug survival (69.3% and 71.9%). After 42 months, Psoriasis Area and Severity Index (PASI) 90 was achieved by 79.6% of patients overall; with a similar proportion of biologic-naïve and biologic-experienced patients achieving PASI90 (79.8% and 79.1%). The mean absolute PASI score reduced from 21.94 to 1.38 in the overall population, 21.90 to 1.24 in biologic-naïve and 22.03 to 1.77 in biologic-experienced patients after 42 months. The decrease in the absolute PASI score was comparable between HLA-Cw6-positive and HLA-Cw6-negative patients. The baseline Dermatology Life Quality Index scores also decreased in the overall patients (10.5 to 2.32) and across all study sub-groups after 42 months. Safety was consistent with the known profile of secukinumab, with no new findings. Conclusion: In this real-world cohort study, secukinumab showed consistently high long-term drug survival and effectiveness with a favourable safety profile.

Atopic Dermatitis: Clinical Aspects and Unmet Needs.

Atopic dermatitis is a common chronic-relapsing, inflammatory and itchy eczematous skin disorder which occurs in both children and adults. AD pathogenesis is complex and several factors are implicated. Pruritus plays a pivotal role in disease's burden, significantly worsening atopic patient quality of life by limiting productivity and daily activities. AD diagnosis relies still on the experience of the healthcare professional and there are several unmet needs as for the diagnostic criteria, the management and the recognition of the burden of the disease. In this paper we present an indeep focus on the main clinical features of AD and the major unmet needs that should be addressed in the next research.

Acral perineurioma: A case report of a rare neoplasm successfully treated with autologous skin graft reconstructive surgery.

Soft tissues perineurioma is a rare nerve sheath tumor that affects most of all the subcutaneous tissue. Even if it could present as a large mass, it is a benign neoplasm for which a complete surgical excision represents the gold standard treatment. Considering that it usually affects acral sites of young people, it can be challenging to perform a reconstructive surgery that allows a full functional recovery. We report the case of a woman in her 20s presenting a perineurioma of the sole of the right foot, a nodule of about 2 cm of diameter that compromised the support of the foot on the ground. We performed a radical surgical excision with no recurrence after 3 years of follow up and we obtained a full functional recovery thanks to an autologous full-thickness skin graft.

Guselkumab for the treatment of psoriasis: a 60-week real-life multicenter retrospective experience.

BACKGROUND: Real-world data for guselkumab, the first interleukin-23 inhibitor approved to treat moderate-to-severe psoriasis, are scarce. This study represents the first 60-week, real-life, multicenter, retrospective experience to investigate the effectiveness, safety, tolerability, and drug retention of guselkumab in psoriatic patients. RESEARCH DESIGN AND METHODS: Clinical information was collected at baseline and at weeks 12, 24, 36, 48, and 60. RESULTS: The mean baseline Psoriasis Activity Severity Index (PASI) reduced from 14.2 to 3.1 at week 12 and decreased to around 0 at weeks 36, 48, and 60. PASI 75, PASI 90, and PASI 100 were 100%, 96.8%, and 83.9% at week 60, respectively. Multiple logistic regression analysis showed that neither body mass index >30, smoking, ≥3 comorbidities, difficult-to-treat areas, nor a failure to ≥2 prior biologic treatments significantly influenced PASI reduction (p > 0.05). CONCLUSIONS: Our findings confirm guselkumab as an appropriate therapeutic option in routine clinical practice, especially when dealing with complex patients with comorbidities or previous failure to biologic treatments.

Use of Apremilast® in the psoriasis treatment: a real-life multicenter Italian experience.

BACKGROUND: Apremilast® (Amgen, Thousand Oaks, CA, USA) is the first small molecule approved for the treatment of moderate-to-severe psoriasis in adult patients; however, real-life data are still limited. We investigated the effectiveness and safety of this drug in a multicenter real-world setting. METHODS: We retrospectively reviewed data from all psoriatic patients who received at least one dose of Apremilast® (Amgen) and collected demographic data and medical history at baseline and periodically for 36 months. RESULTS: A total of 111 patients entered in the study. The mean drug survival duration was 21.8±10.6 months; however, it was significantly shorter when comorbidities were ≥3 and if biologic drugs were previously administered. ΔPASI90 was achieved in 29% of patients and ΔPASI50 in 68% at T4; the rate of ΔPASI improvement increased progressively at T12, T24, T36 in patients who continued to receive Apremilast® (Amgen). At the end of the study 50 patients discontinued the treatment because of adverse events (19.8%), primary failure (19%) or secondary failure (6.3%). CONCLUSIONS: Apremilast® (Amgen) proved to be an effective, safe, and manageable drug, showing effectiveness also in difficult-to-treat patients with psoriasis, with a favorable tolerability profile and a potentially valid weight loss effect. We believe that treating patients with few comorbidities who are naive to biological therapy may result in higher response rates and longer mean drug survival.

Dimethyl fumarate treatment for psoriasis in a real-life setting: A multicentric retrospective study.

Dimethyl fumarate (DMF) is a fumaric acid esters derivate approved for plaque psoriasis as first-line systemic therapy. It has been available in Italy since 2017 and an increasing number of patients are treated with this drug. To evaluate DMF effectiveness, side effects and drug survival in a dermatological real-life setting. We performed a retrospective multi-center study in five dermatologic clinics in Emilia-Romagna, Northern Italy, which included all consecutive patients affected by moderate-severe psoriasis treated with DMF. We assessed effectiveness (in terms of PASI50 and PASI75 in an intention to treat observation) and safety (occurrence of side effects) of DMF and their association with demographic and disease characteristics, mean daily dose taken and treatment discontinuation. We included 103 patients, 78 (75.72%) had at least one comorbidity including 19 (18.44%) with a history of cancer; the mean treatment duration was 23.61 ± 17.99 weeks (min 4, max 130) and the mean daily dose was 262.13 ± 190.94 mg. Twenty-four patients (23.30%) reached PASI75 at week 12, while a further 18 patients (17.47%) reached it at week 26. Side effects occurred in 63 patients (61.16%), the most frequent were diarrhea, epigastric discomfort, nausea, and flushing. Sixteen patients (15.53%) showed an alteration of laboratory tests. In some cases side effects were transitory, while in 53 patients (51.45%) they led to cessation of therapy. The median daily dose showed a direct association with PASI50 achievement and an indirect association with treatment discontinuation. Our study shows the peculiarities of DMF in a real-world setting: effectiveness is often reached after 12 weeks of treatment and side effects could limit the continuation of the therapy but, at the same time, DMF has no major contraindications and, due to the wide range of dosage, it can allow both to manage side effects and to personalize the prescription for each patient.

Management of patients with atopic dermatitis undergoing systemic therapy during COVID-19 pandemic in Italy: Data from the DA-COVID-19 registry.

BACKGROUND: Few and small studies have described the management of immunomodulant/immunosuppressive therapies or phototherapy in atopic dermatitis (AD) patients during coronavirus disease 2019 (COVID-19) pandemic. METHODS: A national registry, named DA-COVID-19 and involving 35 Italian dermatology units, was established in order to evaluate the impact of COVID-19 pandemic on the management of adult AD patients treated with systemic immunomodulant/immunosuppressive medications or phototherapy. Demographic and clinical data were obtained at different timepoints by teledermatology during COVID-19 pandemic, when regular visits were not allowed due to sanitary restrictions. Disease severity was assessed by both physician- and patient-reported assessment scores evaluating itch intensity, sleep disturbances, and AD severity. RESULTS: A total of 1831 patients were included, with 1580/1831 (86.3%) continuing therapy during pandemic. Most patients were treated with dupilumab (86.1%, 1576/1831) that was interrupted in only 9.9% (156/1576) of cases, while systemic immunosuppressive compounds were more frequently withdrawn. Treatment interruption was due to decision of the patient, general practitioner, or dermatologist in 39.9% (114/286), 5.6% (16/286), and 30.1% (86/286) of cases, respectively. Fear of increased susceptibility to SARS-CoV-2 infection (24.8%, 71/286) was one of the main causes of interruption. Sixteen patients (0.9%) resulted positive to SARS-CoV-2 infection; 3 of them (0.2%) were hospitalized but no cases of COVID-related death occurred. CONCLUSIONS: Most AD patients continued systemic treatments during COVID pandemic and lockdown period, without high impact on disease control, particularly dupilumab-treated patients.

Comparative study of imiquimod 3.75% vs. photodynamic therapy for actinic keratosis of the scalp.

BACKGROUND/PURPOSE: To assess efficacy, tolerability, adverse effects, recurrence, and aesthetic results of imiquimod 3.75% vs. photodynamic therapy with 5-aminolaevulinic acid (MAL-PDT) for actinic keratosis (AK). METHODS: A small randomized, intraindividual right-left pilot study for AK treatment of multiple scalp lesions was performed. Patients were treated with imiquimod and subsequently MAL-PDT (on opposite sides of the scalp) 14 days apart. Study end points were evaluated with clinical and dermoscopic examinations at 1, 3, 6, and 12 months. RESULTS: Nine male bald patients were enrolled. Imiquimod achieved a slightly higher overall clearance rate than MAP-PDT (68.1% vs 56.5%). According to AK degree of severity, clearance rates were greater for degree I and III with imiquimod (68.8%, 64.5% and 75% with imiquimod vs. 48%, 69.8%, and 66.7% for MAL-PDT, respectively). At 12 months, a slightly higher total recurrence rate was noted for imiquimod compared with MAL-PDT (9.9% vs. 8.6%); new lesions were 2 degree I for imiquimod and 4 degree I for MAL-PDT. For both treatments, pain was moderate/strong (even if MAL-PDT seems to be less tolerable) adverse effects are common and transient; aesthetic results excellent. CONCLUSION: Both imiquimod and MAL-PDT were effective in the reduction in the number of AK. In the long-term, both present a good effectiveness maintained over time with excellent aesthetic results. A combination or sequential therapy could optimize the management of the cancerization field.

Management of psoriatic arthritis in rheumatology and dermatology settings: sub-analysis of the Italian population from the international LOOP study.

Psoriatic arthritis (PsA) patients are often treated by dermatology and rheumatology specialities and may receive different treatments. To evaluate the impact of dermatology/rheumatology specialist settings on diagnosis and therapeutic approach in PsA patients. This cross-sectional multicounty study in Italy involved twenty-eight rheumatology or dermatology clinics. Patients with suspected or confirmed PsA were examined by both a dermatologist and a rheumatologist. A total of 413 patients were enrolled and 347 (84%) were diagnosed with PsA. The majority of patients were enrolled from a rheumatology setting (N = 224, 64.6%). Patients with PsA in the dermatology settings had significantly higher disease activity, including skin involvement and musculoskeletal symptoms. Time from PsA onset to diagnosis was 22.3 ± 53.8 vs. 39.4 ± 77.5 months (p = 0.63) in rheumatology and dermatology settings; time from diagnosis to initiation of csDMARD was 7.3 ± 27.5 vs. 19.5 ± 50.6 months, respectively (p < 0.001). In contrast, time from diagnosis to bDMARD use was shorter in dermatology settings (54.9 ± 69 vs. 44.2 ± 65.6 months, p = 0.09, rheumatology vs. dermatology), similar to the time taken from first csDMARDs and bDMARDs (48.7 ± 67.9 vs. 35.3 ± 51.9 months, p = 0.34). The choice to visit a rheumatologist over a dermatologist was positively associated with female gender and swollen joints and negatively associated with delay in time from musculoskeletal symptom onset to PsA diagnosis. This study highlights a diagnostic delay emerging from both settings with significantly different therapeutic approaches. Our data reinforce the importance of implementing efficient strategies to improve early identification of PsA that can benefit from the integrated management of PsA patients. Key Points • A diagnostic delay was observed from both dermatology and rheumatology settings with significantly different therapeutic approaches. • Shared dermatology and rheumatology clinics offer the combined expertise to improve in the early identification and management of PsA.

Outcome following a short period of adalimumab dose escalation as rescue therapy in psoriatic patients.

BACKGROUND: Advances in biologic treatments have led to a new therapeutic frontier for moderate-to-severe psoriasis. Nevertheless, the efficacy of anti-TNFα decreases with time, requiring adjustments to maintain valuable Psoriasis Area and Severity Index (PASI) and Dermatology Life Quality Index (DLQI) responses. OBJECTIVES: To evaluate the efficacy and safety of adalimumab dose escalation (40 mg, subcutaneous, once a week for 24 weeks) in psoriatic adult patients with secondary loss of response (PASI ≥50 to ≤75 or PASI≥75 and DLQI ≥5). MATERIALS AND METHODS: A multicentre, observational study involving different Italian third-level referral centres for psoriasis enrolled a total of 64 adult patients with moderate-to-severe psoriasis who were treated with adalimumab and experienced a secondary loss of response. Primary end-points were PASI> 75 or PASI ≥50 to ≤ 75 with DLQI ≤ 5, and the secondary end-point was the ability to maintain a therapeutic response, resuming adalimumab every other week. RESULTS: At Week 16 and Week 24, 29/64 (45.3%) and 35/64 (54.6%) responded based on PASI, and mean DLQI was 4.9 and 4.09, respectively. At Week 36 and Week 48, 45.3% and 28.1% patients achieved the second end-point, respectively. No adverse events were recorded except for one patient with recurrent tonsillitis. CONCLUSION: Adalimumab escalation could be considered in cases with loss of response before switching to alternative biologic therapy.

The Italian Mastocytosis Registry: 6-year experience from a hospital-based registry.

AIM: We collected 'real-life' data on the management of patients with mastocytosis in the Italian Mastocytosis Registry. METHODS: Six hundred patients diagnosed with mastocytosis between 1974 and 2014 were included from 19 centers. RESULTS: Among adults (n = 401); 156 (38.9%) patients were diagnosed with systemic mastocytosis. In 212 adults, no bone marrow studies were performed resulting in a provisional diagnosis of mastocytosis of the skin. This diagnosis was most frequently established in nonhematologic centers. In total, 182/184 pediatric patients had cutaneous mastocytosis. We confirmed that in the most patients with systemic mastocytosis, serum tryptase levels were >20 ng/ml and KIT D816V was detectable. CONCLUSION: The Italian Mastocytosis Registry revealed some center-specific approaches for diagnosis and therapy. Epidemiological evidence on this condition is provided.

PKCε promotes human Th17 differentiation: Implications in the pathophysiology of psoriasis.

PKCε is implicated in T cell activation and proliferation and is overexpressed in CD4+ -T cells from patients with autoimmune Hashimoto's thyroiditis. Although this might induce the suspicion that PKCε takes part in autoimmunity, its role in the molecular pathophysiology of immune-mediated disorders is still largely unknown. We studied PKCε expression in circulating CD4+ -T cells from patients with psoriasis, a skin disorder characterized by an increased amount of Th17 cells, a CD4+ subset that is critical in the development of autoimmunity. Although the mechanisms that underlie Th17 differentiation in humans are still unclear, we here show that: (i) PKCε is overexpressed in CD4+ -T cells from psoriatic patients, and its expression positively correlates with the severity of the disease, being reduced by effective phototherapy; (ii) PKCε interacts with Stat3 during Th17 differentiation and its overexpression results in an enhanced expression of Stat3 and pStat3(Ser727); iii) conversely, when PKCε is forcibly downregulated, CD4+ -T cells show lower levels of pStat3(Ser727) expression and defective in vitro expansion into the Th17-lineage. These data provide a novel insight into the molecular mechanisms of Th17 cell polarization that is known to play a crucial role in autoimmunity, pinpointing PKCε as a potential target in Th17-mediated diseases.

Claimed Effects, Outcome Variables and Methods of Measurement for Health Claims Proposed Under European Community Regulation 1924/2006 in the Framework of Maintenance of Skin Function.

Evidence suggests a protective role for several nutrients and foods in the maintenance of skin function. Nevertheless, all the requests for authorization to use health claims under Article 13(5) in the framework of maintenance of skin function presented to the European Food Safety Authority (EFSA) have received a negative opinion. Reasons for such failures are mainly due to an insufficient substantiation of the claimed effects, including the choice of inappropriate outcome variables (OVs) and methods of measurement (MMs). The present paper reports the results of an investigation aimed at collecting, collating and critically analyzing the information with relation to claimed effects (CEs), OVs and MMs related to skin health compliance with Regulation 1924/2006. CEs, OVs and MMs were collected from both the EFSA Guidance document and from the authorization requests of health claims under Article 13(5). The critical analysis of OVs and MMs was based on a literature review, and was aimed at defining their appropriateness (alone or in combination with others) in the context of a specific CE. The results highlight the importance of an adequate choice of OVs and MMs for an effective substantiation of the claims.

Notalgia paresthetica: factors associated with its perceived severity, duration, side, and localization.

BACKGROUND: Notalgia paresthetica (NP) is a disorder characterized by pruritus localized to the patient's back. Little is known about predictors of severity, duration, side, and localization. OBJECTIVE: To identify factors associated with perceived severity, duration, side, and localization of NP. METHODS: In a cross-sectional study, disease severity, duration, side, and localization were compared among the considered variables. Multivariate analysis was used to assess each variable contribution in predicting disease severity and its duration. RESULTS: Sixty-five patients were recruited. Disease involved more female than male patients (Female/Male: 1.6) and after adjusting for all potential confounders, it was perceived as more severe in females (OR = 7.3, 95% CI = 2-26.3, P < 0.01). NP was reported more frequently on the right side among patients sleeping on the left side and conversely (P < 0.05). A higher disease duration was significantly linked to a higher body mass index (OR = 4.8, 95% CI = 1.3-17.1, P < 0.05). CONCLUSION: Our study linked female gender to worse disease severity, a higher body mass index to longer disease duration, and prevailing sleep position to NP side expression. The sleeping position should be considered a possible target for treating the disease.
