Drug Survival of Upadacitinib and Predicting Factors of Discontinuation in Adult Patients Affected by Moderate-to-Severe Atopic Dermatitis: An Italian Multicenter Analysis

Background: Limited real-world data are available on upadacitinib drug survival in patients with atopic dermatitis (AD). Objectives: To investigate upadacitinib drug survival, and the reasons and predictors of drug discontinuation in AD patients. Methods: All consecutive patients aged 18-75 years, affected by moderate-to-severe AD, and treated with upadacitinib for more than 1 month at dermatological clinics were included during November 2020-August 2023. Upadacitinib survival was investigated through Kaplan-Meier survival analysis and the predictors through multivariable logistic regression analysis. Results: Overall, 325 adult AD patients (mean (SD) age, 38.6(15.6) years) had a 1-year and 1.5-year upadacitinib drug survival of 91.5% and 80.2%, respectively. The main reasons for drug discontinuation (25/325, 7.7%) were adverse events (4.9%), including cutaneous or infectious diseases (1.5%), such as acne and herpes zoster; blood test changes (1.2%), including hypercholesterolemia, creatine phosphokinase or liver enzyme elevation, and lymphopenia; urinary or respiratory infections (0.9%); deep venous thrombosis (0.3%); malignancies (0.3%); loss of consciousness (0.3%); and arthralgias (0.3%); followed by ineffectiveness (0.6%). No specific characteristic was significantly associated with an increased risk of upadacitinib discontinuation. Conclusions: Our findings show that upadacitinib was effective in moderate-to-severe AD after more than 1 year of continuous treatment but point to the need for clinical and laboratory monitoring of patients.

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.

Etiology of Chronic Leg Ulcers in a Dermatologic Wound Clinic: A Retrospective Observational Study

BACKGROUND: Chronic leg ulcers affect approximately 1% to 2% of the European population, with an increasing prevalence. The treatment of chronic wounds is a socioeconomical problem worldwide. PURPOSE: The main purpose of the current investigation was to detect the etiology of leg ulcers treated in a dermatologic wound clinic from January 1, 2010, to December 31, 2019. METHODS: This retrospective observational study was performed at the Dermatologic Clinic of Spedali Civili in Brescia, Italy. The authors enrolled 465 patients with chronic leg ulcers. RESULTS: The 3 most represented causes of ulcers were vascular (238 patients, 51.2%), inflammatory (71 patients, 15.3%) and traumatic (43 patients, 9.3%). Altogether, a total of 13 different entities were identified as a cause of leg ulcer. CONCLUSION: Vascular genesis was the most common etiology of leg ulcers in this population, even though uncommon causes were also represented. These findings are in agreement with other studies reported in the literature.

Contact allergy in children with and without atopic dermatitis: an Italian multicenter study

Background

Contact allergy and atopic dermatitis (AD) are both common inflammatory T cell‐mediated diseases and many factors may influence the prevalence of contact allergy in AD patients. In children, their possible correlation was debated with conflicting results.

Objectives

The present study aimed to assess the prevalence of contact sensitivity in children and to investigate the association with AD.

Materials and methods

A retrospective multicentre study on children aged from 0 to 14 years patch tested between January 2017 and December 2018 was performed. Children were consecutively patch tested with the SIDAPA (Società Italiana Dermatologia Allergologica Professionale Ambientale) baseline series.

Results

Among the 432 children investigated for contact allergy, 125 (28.9%) showed a positive reaction to at least one of the allergens tested, with a higher prevalence of positive patch test reactions in girls (32.3%) than in boys (25.0%). The most frequent contact allergens were nickel sulphate (10.2%), cobalt chloride (6.7%), methylisothiazolinone (3.7%), fragrance mix‐2 (3.2%), potassium dichromate (2.8%), fragrance mix‐1 (2.1%) and methylchloroisothiazolinone/methylisothiazolinone (2.1%). One‐hundred‐three children (23.8%) suffered from AD showing a higher prevalence of positive patch test (36.9%) compared to children without AD (26.4%).

Conclusions

Despite the topic being still controversial, the present study suggests a consistent prevalence of contact allergy among children with higher sensitivity rate among children with AD than without AD.

Diagnosis and treatment of classic and iatrogenic Kaposi's sarcoma: Italian recommendations

Kaposi's sarcoma (KS) is a lymphangioproliferative disorder associated with Human herpesvirus 8 (HHV8) infection. Four clinical subtypes are recognized: classic, endemic, epidemic (HIV-related) and iatrogenic. KS diagnosis is based on clinical features, histopathological assessment, and HHV8 serology. Classic KS is usually skin-limited and has a chronic course, while the iatrogenic variant may show mucosal, nodal or visceral involvement. Clinical staging is fundamental to guide the management. Localized disease may be treated with different local therapies, even if there are no randomized trials comparing these different modalities. Aggressive, disseminated KS and cases with visceral involvement usually require systemic chemotherapy, most commonly vinblastine, bleomycin or paclitaxel. Iatrogenic KS needs immunosuppression tapering/withdrawal and, if possible, switch to m-TOR inhibitors in post-transplant KS. The present work by a panel of Italian experts provides guidelines on KS diagnosis and management based on a critical review of the literature and a long and extensive personal experience.

Echocardiographic evaluation of diastolic dysfunction in young and healthy patients with psoriasis: A case-control study

Psoriasis is a systemic inflammatory disease with a great prevalence in general population. The inappropriate activation of the cellular immune system has been hypothesized to be an independent cardiovascular risk factor, given the higher incidence of cardiovascular disorders in psoriatic patients. Echocardiographic abnormalities have been demonstrated too: the aim of our study was to evaluate the presence of preclinical cardiac dysfunction in a cohort of psoriatic patients without cardiovascular risk factors. We enrolled 52 patients with the diagnosis of chronic plaque psoriasis, compared with a control group not affected by any relevant systemic diseases and inflammatory disorders. In all patients and control group, echocardiographic conventional and tissue Doppler (TDI) studies were conducted. The analysis of echocardiographic parameters revealed normal dimension, mass and systolic function of the left ventricle. Left ventricular diastolic dysfunction was found in 36.5% patients in the psoriasis group versus 0% in control group, and significant reduction of the E/A ratio was found also for the right ventricle. A significant increase of mitral regurgitation has been found in psoriatic patients (p=0.005). The early recognition of cardiovascular pre-clinic disease in psoriatic patients may guide a strict follow up and an early treatment, potentially improving cardiovascular prognosis.

Plasma levels of polychlorinated biphenyls and risk of cutaneous malignant melanoma: A hospital-based case-control study

Polychlorinated biphenyls (PCB) have been classified by the International Agency for Research on Cancer (IARC) in Group 1 as carcinogenic to human, based on sufficient evidence in humans of an increased risk of cutaneous malignant melanoma (CMM), however few studies have been done in the general population. This study examined the relationship between PCB plasma levels and risk of CMM adjusting for sun sensitivity and sun exposure in a province of Northern Italy (Brescia), where a chemical factory produced PCBs from 1938 to 1984 causing human contamination. A case-control study of 205 CMM patients and 205 control subjects was conducted. Cases and controls were assayed for plasma levels of 33 PCB congeners. No associations was found between risk of CMM and plasma levels of total PCB (OR = 0.81; 95% CI: 0.34-1.96 for highest vs lowest quartile) or specific congeners. The study confirmed the association with light skin colour (OR = 3.00; 95% CI: 1.91-4.73), cumulative lifetime UV exposure (OR = 2.56; 95% CI: 1.35-4.85) and high level of education (OR = 1.45; 95% CI: 1.03-2.05). This case-control study does not support the hypothesis of an association between current plasma levels of PCBs and CMM development in the general population.

Diagnosis and management of moderate to severe adult atopic dermatitis: a Consensus by the Italian Society of Dermatology and Venereology (SIDeMaST), the Italian Association of Hospital Dermatologists (ADOI), the Italian Society of Allergy, Asthma and Clinical Immunology (SIAAIC), and the Italian Society of Allergological, Environmental and Occupational Dermatology (SIDAPA)

Atopic dermatitis (AD) is a chronic immune-mediated inflammatory skin disease, currently recognized as a systemic disease possibly burdened by various comorbidities, including, but not limited to, other allergic conditions. Management guidelines issued by American and European dermatology and allergy scientific societies are available. However, some discrepancies exist in these guidelines, and some aspects of the management process, including diagnosis and severity assessment, as well as therapy duration and switch criteria, are not fully clarified by existing guidelines. Moreover, biologics such as dupilumab have now entered the therapeutic scenario of moderate-to-severe AD, offering a great opportunity to treat effectively and safely in need AD patients. For all these reasons, four Italian dermatology and allergy scientific societies joined to provide practical guidance for the management of moderate-to-severe adult AD suitable for the Italian clinical practice. Through a modified Delphi procedure, consensus was reached by 63 Italian dermatologists and allergists experienced in the management of adult AD on 14 statements covering five AD areas of interest, i.e. diagnosis, severity definition, current systemic therapies, eligibility criteria to biologic treatments, and comorbidities, with the aim to define treatment goals and improve adult AD management. The potential usefulness of a multidisciplinary approach is also underlined, given the complexity of AD and its comorbidities.

Back to the future: a new topical approach for mild-to-moderate psoriasis

Psoriasis is a chronic-relapsing skin disorder which requires long-term treatments. Therapeutic options for psoriasis include topical treatments, phototherapy and systemic therapy. However, those treatments, and particularly the topical drug therapies, may present some limitations, including poor efficacy/tolerability ratio and lack of adherence. Recently, the supersaturated aerosol foam formulation of the fixed combination calcipotriene plus betamethasone dipropionate (Cal/BD) has gained major attention because it overcomes some of the limitations associated with other topical treatments. This fixed-combination has increased efficacy compared with its individual components. Moreover, the alcohol-free aerosol foam formulation allows a higher penetration of the active ingredients into the skin, resulting in enhanced bioavailability and, consequently, in better clinical outcomes than other products with the same components. Given the short duration of therapy course and the fast onset of action, a reduced amount of Cal/BD foam formulation would be required for the treatment of psoriasis patients, resulting also in cost saving. Therefore this novel formulation could represent an alternative to other topical agents and a first-line therapy in the treatment of mild and mild-to-moderate psoriasis.

Vismodegib in the treatment of basal cell carcinoma: indications for clinical practice

Basal cell carcinoma (BCC) is a frequent skin cancer which can cause substantial morbidity due to its location on the face, its frequency of relapse and its capacity to invade local tissues. The primary treatment of BCC usually involves surgery or radiotherapy. In patients who have exhausted surgical and radiotherapy options or with metastatic BCC, guidelines recommend the use of the Hedgehog pathway inhibitor vismodegib. This molecule is indicated for the treatment of adults with metastatic BCC, or with locally advanced BCC which has recurred following surgery or who are not eligible to surgery or radiation. This paper aims to provide suggestions on the optimal management of BCC patients treated with vismodegib in clinical practice, according to the large experience gained by a group of Italian dermatologists and oncologists. In particular, the focus of this paper will be on the monitoring of patients and the management of adverse events.

Treatment patterns with systemic antipsoriatic agents in childhood psoriasis: an Italian database analysis

BACKGROUND

The majority of available systemic therapies have never been systematically investigated in moderate to severe childhood plaque psoriasis. For this reason, treatment preferences for moderate to severe psoriasis in childhood are still unknown. The aim of this study was to investigate the systemic treatment patterns of moderate to severe psoriasis in children and adolescents aged 18 or older in Italy. Additional secondary outcomes were duration of treatment and reasons for discontinuation.

METHODS

In order to define differences in treatment patterns, we performed a chart review of all consecutive patients treated with systemic drugs during an index period of 5 years. Consecutive sampling of all patients with psoriasis aged ≤18 years, who had been treated with at least one systemic drug over a 5-year period, was made.

RESULTS

The records of 58 consecutive patients, 27 males, 31 females. with moderate to severe psoriasis treated with at least one systemic therapy were reviewed. The median age (standard deviation) at the start of the first systemic treatment was 11.7±3.7 years. The most preferred first-line systemic treatment was cyclosporine, which was administered as first systemic treatment in 53.4% of patients, followed by acitretin in 22.4% of patients, etanercept and PUVA respectively in 8.6%, methotrexate in 6.8%. 48.2% of patients received a second systemic treatment due to inefficacy or side effects of the first-line therapy during the index period. Because of the small sample, and voluntary contribution, selection bias may have occurred.

CONCLUSIONS

A considerable variation in the management of the first-line systemic therapy in children with moderate to severe psoriasis was observed. Cyclosporine was most commonly preferred as a first-line treatment. The availability of new therapeutic agents could change the scenario of treatment patterns in childhood psoriasis.

Increased risk of venous thromboembolism in patients with bullous pemphigoid. The INVENTEP (INcidence of VENous ThromboEmbolism in bullous Pemphigoid) study

Activation of blood coagulation has been demonstrated in bullous pemphigoid (BP), a rare autoimmune blistering disease, potentially leading to a prothrombotic state. In order to evaluate the incidence of venous thromboembolism (VTE) in BP, a cohort study was carried out on 432 BP patients (59% females; median age 76 years, interquartile range [IQR]: 68-82). At diagnosis, autoimmune bullous skin disorder intensity score (ABSIS) was calculated. VTE incidence was standardised with rates of the general population. Multivariable Cox proportional hazard model was used to estimate the hazard ratio of VTE according to ABSIS and concomitant risk factors. During a median follow-up of 4.2 years, 31 objectively-diagnosed VTE events were recorded. The incidence rate of VTE (per 1000 patient-years) was 17.2 overall (95% confidence interval [CI]: 11.1-23.2), 56.7 (95%CI: 33.0-80.4) during acute phase (22 VTE) and 6.3 (95%CI: 2.8-11.3) during remission (9 VTE). The standardised incidence ratio was 4.06 (95%CI: 2.73-5.65), higher during the acute phase (14.86, 95%CI: 9.20-21.88) than during remission (1.48, 0.66-2.63). The adjusted hazard ratio of VTE was 2.74 (95%CI: 1.07-7.04) for ABSIS > 48 vs ABSIS < 28, and 2.56 (95%CI: 1.00-6.70) in patients with ≥ 2 concomitant risk factors. In conclusion, BP patients have a 15-fold increased VTE risk during acute phase, proportional to disease severity and heightened by concomitant risk factors.

Pseudolymphoma tattoo-induced

Tattooing has become more and more popular in today's society. The most common dermatological tattoo complications are represented by hypersensitivity reaction to tattoo pigments like irritant and allergical contact dermatitis, development of lichenoid areas and granulomatous responses, such as sarcoid granulomas or foreign body granulomas. Less frequently patients developing discoid lupus erythematous have been reported. Pseudolymphoma is an uncommon reactive lymphocytic proliferation mimicking the histological and clinical features of a malignant skin lymphoma. We herein report a pseuldoymphoma limited to the red area of a multicolour tattoo of the leg.

Cost-effectiveness analysis of TNF-alpha blockers for the treatment of chronic plaque psoriasis in the perspective of the Italian health-care system

The cost-effectiveness of biological treatments for psoriasis is not well determined and may vary from country to country. The objectives of this study was to perform a cost-effectiveness analysis of infliximab compared with other anti-tumor necrosis factor-alpha agents for the treatment of psoriasis in Italy. The incremental cost-effectiveness ratio per patients achieving at least 75% improvement in the psoriasis area and severity index assessed over 24- and 48-50-week periods was calculated. Efficacy data were drawn from randomized controlled trials when available or from open label studies. Considering patients achieving psoriasis area and severity index at week 24 and 48-50, infliximab was dominant (more effective and less costly) over etanercept given at 50 mg twice weekly. In contrast, infliximab was not dominant over etanercept at other dosages or over adalimumab. When considering the impact of therapy on quality of life at Week 12 using the Dermatology Life Quality Index equal to zero, infliximab resulted more effective and less costly than etanercept. Therefore, infliximab seems to be cost-effective in the therapy of psoriasis. Further cost-efficacy evaluations based on head-to-head trials are necessary to address health economic considerations.

Syringotropic cutaneous T cell lymphoma treated with PUVA therapy

Syringotropic cutaneous T cell Lymphoma (SCTCL) is a rare localized variant of CTCL. It is characterized by erythematous papules that, at histological examination, show dense dermal infiltrates of atypical T cells, that are preferentially located around hyperplastic eccrine sweat glands and ducts, with absent or minimal epidermotropism. Its relationship with mycosis fungoides and other CTCLs is not clarified and is still under discussion. Several treatment approaches have been suggested, but therapeutic results are often disappointing. We report the case of a patient with typical clinical and histopathological features of SCTCL and an excellent response to PUVA therapy.

Prospects for ultraviolet A1 phototherapy as a treatment for chronic cutaneous graft-versus-host disease

BACKGROUND AND OBJECTIVES

Standard or investigative immunosuppressive therapies for cutaneous chronic graft-versus-host disease (GVHD) may prove not only ineffective but also cause serious adverse effects. Repeated exposure of the skin to ultraviolet radiation in the wavelength range 340-400 nm (so-called ultraviolet A1) was recently reported to have a strong local (intracutaneous) immunomodulatory activity. This study was undertaken to evaluate efficacy and safety of this phototherapy.

DESIGN AND METHODS

Nine patients with cutaneous (4 lichenoid and 5 sclerodermoid) GVHD and mild or no other organ involvement were enrolled. All patients had developed serious drug toxicity and/or opportunistic infections. Phototherapy was administered three times a week.

RESULTS

Complete remission was seen in 5 (2 lichenoid and 3 sclerodermoid) cases and a partial improvement in 4 (2 lichenoid and 2 sclerodermoid) after having received 15.8+/-3.8 (lichenoid GVHD) or 21.6+/-8.0 (sclerodermoid GVHD) sessions of phototherapy. Adverse effects were not registered. At follow-up (range: 6-25 months), two patients with sclerodermoid lesions relapsed after 5 months but responded to another treatment cycle. Patients with lichenoid GVHD showed relapses within one month and prolonged maintenance phototherapy was needed. Problems of drug toxicity and opportunistic infections improved as phototherapy allowed the reduction or interruption of systemic drug therapies.

INTERPRETATION AND CONCLUSIONS

Ultraviolet A1 phototherapy may be considered as an appropriate therapeutic approach for sclerodermoid GVHD with no or mild involvement of internal organs. Patients with lichenoid GVHD should be treated only if they develop serious adverse effects to immunosuppressive therapies and opportunistic infections because of the carcinogenic hazard of high cumulative doses of ultraviolet A1 radiation.

Medium-dose ultraviolet A1 therapy for pityriasis lichenoides et varioliformis acuta and pityriasis lichenoides chronica

BACKGROUND

Ultraviolet A1 (340-400 nm) was found to be effective in the treatment of cutaneous T-cell-mediated diseases.

OBJECTIVE

The purpose of the present study was to assess the efficacy of UVA1 phototherapy for pityriasis lichenoides et varioliformis acuta (PLEVA) and pityriasis lichenoides chronica (PLC).

METHODS

Eight patients (3 with PLEVA and 5 with PLC) received 60 J/cm(2) UVA1 daily until remission. Four patients also had lesions inaccessible to UVA1 that were used as control lesions. Immunocytologic studies of skin infiltrates and circulating T cells were done.

RESULTS

Six patients showed complete clinical and histologic recovery. Two patients with PLC had a partial improvement. Unirradiated control lesions never improved. Serious short-term adverse effects were not encountered. No effects on circulating lymphocytes were reported.

CONCLUSION

UVA1 therapy is an effective and well-tolerated treatment for PLEVA and PLC. The therapeutic activity seems to be related to direct effects on cutaneous inflammatory infiltrates because the lesions in nonexposed cutaneous areas did not respond.

"High-dose" UVA1 therapy of widespread plaque-type, nodular, and erythrodermic mycosis fungoides

BACKGROUND

UVA1 (340 to 400 nm) was found to be effective in the treatment of early-stage mycosis fungoides (MF).

OBJECTIVE

The purpose of this study was to assess the efficacy of UVA1 phototherapy for widespread plaque-type, nodular, and erythrodermic MF.

METHODS

Thirteen patients (8 with stage IB, 4 with IIB, and 1 with III MF) received 100 J/cm(2) UVA1 daily until remission. Four patients also had lesions inaccessible by UVA1 that were considered control lesions. Immunocytologic studies of skin infiltrates and circulating T cells were done before and after the therapy.

RESULTS

Eleven patients showed complete clinical and histologic responses. Two patients had a partial improvement. Unirradiated control lesions never improved. Serious short-term side effects were not recorded. Circulating CD4(+)/CD45RO(+) and CD4(+)/CD95(+) lymphocytes were significantly reduced by the therapy.

CONCLUSION

UVA1 therapy is an effective and well-tolerated treatment for advanced MF. The therapeutic relevance of the effects on circulating lymphocytes remains to be established because lesions in nonexposed cutaneous areas did not respond.
