HIV positive patient treated with ixekizumab.

Abstract: Psoriasis is a immune-mediated, chronic, inflammatory skin dis-ease. In HIV positive (HIV+) patients we usually observe more serious clinical features and recalcitrant course. Furthermore, therapeutic man-agement of HIV+ patient is complex and requires collaboration with the infectious disease specialist. We report the case of a patient affected by severe psoriasis who contracted HIV infection during biological therapy and, subsequently, succesfully treated with ixekizumab.

A case of proliferative nodule arising within blue nevus.

Abstract: Blue nevi are a heterogeneous group of lesions that can display a variety of different clinicopathological characteristics. Although attempts are made to classify each lesion into defined subtypes, there can be overlap between the subtypes. The clinical , dermoscopic and histolopathologic features of a case of proliferative nodule arising within blue nevus is discussed. Running title: Blue nevi are an heterogeneous group of melanocytic lesions blue tinctorial properties. Proliferative nodules are rare benign lesions often present at birth as a component of a large congenital melanocytic nevi, congenital or acquired nevi. We first report a case of proliferative nodule arising within blue nevus.

How lockdown measures, during COVID-19 pandemic, matter on psoriatic patient's perception: Study on 600 patients on biologic therapy.

BACKGROUND: The outbreak of coronavirus disease-2019 (COVID-19) is a public health crisis of global proportion. In psoriatic patients treated with biologic agents, evidence is not yet available on susceptibility to infection with the novel SARS-CoV-2 coronavirus, and data about the perception of COVID-19 and its impact on these patients are lacking. AIMS: The aim of this observational, spontaneous study was the evaluation of the impact of anti COVID-19 measures in "fragile population" such as patients with a chronic inflammatory disease. Thus, we evaluated the impact of perceived risk on quality of life of patients with moderate to severe psoriasis, in our outpatient clinic, and how their perceptions changed before and after the adoption of Covid-19 emergency measures following the Italian Ministerial Decree in March 9, 2020. METHODS: Using a series of questions, our study surveyed adult patients with moderate to severe psoriasis receiving treatment with biologic agents (n = 591), before and after the adoption of COVID-19 emergency measures. RESULTS: Most patients (97%) had been sufficiently informed by healthcare staff about COVID-19 spread. A significant change was observed in social activity reduction before and after the adoption of the measures (18% vs. 90% of patients; P < 0.0001). Similarly, patients were more likely to suspend ongoing therapy after the measures were adopted than before (87% vs. 34% of patients; P < 0.0001). Following the measures, older patients were significantly more inclined to suspend therapy and reduce social activities than younger patients. CONCLUSIONS: Government COVID-19 emergency measures further curtailed already reduced social activities in psoriatic patients, and led to a greater inclination to suspend biologic therapy, more so in older patients, despite there being no evidence to support this suspension. These vulnerable patients may need support from clinicians in order to maintain treatment adherence.

PET-guided Switch from Immunotherapy to Targeted Therapy in a Metastatic Melanoma Patient: a personalized approach.

An early identification of non-responders in oncology is of crucial importance to rapidly switch treatment regimens. Here we report a positron emission tomography, (PET)-guided switch from immunotherapy to targeted therapy in a patient affected by metastatic melanoma. We describe the case of a 78-years-old male patient diagnosed with nodular melanoma, submitted to baseline PET/CT with 18fluorodeoxyglucose (18F-FDG) that showed cutaneous and skeletal metastases (stage IV). The patients started immunotherapy with pembrolizumab. A PET/CT performed 3 months after the start of immunotherapy demonstrated progressive metabolic disease both at skeletal and cutaneous level, confirmed also by the biopsy. As patients resulted positive for BRAF V600k mutation, treatment regimen was rapidly switched to combined anti-BRAF/MEK targeted therapy. The PET/CT performed 3 months later, showed almost complete metabolic response. Ten months after the beginning of targeted therapy, the patient continues to present a durable metabolic response. PET/CT with 18F-FDG may help in monitoring the response to treatment in metastatic melanoma thus defining personalized therapeutic pathways.

Benefit of a topic ointment as co-medication with biologic drugs for the management of moderate-severe psoriasis: a prospective, observational real-life study.

BACKGROUND: Psoriasis is a multifactorial chronic inflammatory skin disease characterized by erythemato-squamous lesions with a chronic relapsing course. The desease clinical activity (PASI) and the patient's quality of life (DLQI) are the main elements to assess for setting up a correct therapeutic management. OBJECTIVES: The aim of the study was to evaluate the management of the patient with moderate-severe psoriasis in therapy with biological drugs and to establish the difference in the achievement of PASI 90 and DLQI 0-1 between a group of patients treated with only biological drugs and a group of patients receiving biologic therapy in combination with a topical ointment. METHODS: We conducted a prospective, observational real-life study enrolling 60 patients with moderate to severe psoriasis and divided in two groups: Group A patients treated with biological drugs, Group B patiens treated with biological drugs in association with an ointment composed of betamethasone, salicylic acid and ammonium sulpho-ichtyolate, applied 2 times a day. PASI and DLQI were evaluated at study beginning (T0) for both study groups, after 12 weeks (T3) for sample in therapy with biological drugs and after 24 weeks (T6) for sample in co-medication therapy. RESULTS: The two-way ANOVA method was used to evaluate the standard deviations (SD): at T3 and T6 Group B obtained a significant PASI reduction and improvement of DLQI (* p value <0.05) compared to Group A. CONCLUSIONS: Our study shown that the patients treated with biologics in co-medication with topical therapy reached a significantly higher PASI and DQLI compared with those treated with only biologics. Furthermore we observed that the association with topical oinment showed more efficacy in the treatment of areas such as palm-plantar region, that is often difficult-to-treat region, even for biologic drugs.

A case of hidradenitis suppurativa linked to trisomy 1q.

Hidradenitis suppurativa (HS) is a chronic relapsing disorder of the apocrine gland affecting mainly areas subjected to friction (e.g. the axillae, groin, perineum and medial aspects of the thighs). This condition can be linked to different comorbidities: autoimmune and inflammatory disease, hormone-related disorders, obesity and the metabolic syndrome, as well as rare syndromes such as Bazex-Dupré-Christol, Down's, KID, PAPASH, PASS, PASH, and SAPHO syndromes, or Dowling-Degos disease. We report a case of severe HS in a patient with Trisomy 1q;13, a very rare cytogenetic anomaly characterized by severe anomalies including dysmorphisms, multiple congenital malformations, heart defects and intellectual disability.

Efficacy and tolerability of a lotion containing triethyl citrate, ethyl linoleate, and GT peptide-10 in the adjuvant treatment of hidradenitis suppurativa: Real-life data.

Hidradenitis suppurativa (HS) is a chronic disorder of terminal follicular epithelium in the apocrine gland-bearing areas. The long term therapy is based mainly on topical and/or systemic antibiotic use that could result in antibiotic resistance. The aim of our study was to present the real-life experience based on the efficacy and tolerability of a novel lotion containing triethyl-citrate, ethyl-linoleate, and g-peptide-10 in the treatment of mild to moderate HS that has already shown effectiveness in acne treatment. This was an open-label study on 30 patients of both sexes affected by HS. Patients were divided into two groups: 15 with Hurley I and 15 with Hurley II-III. The subjects were treated with the topical lotion, three-times-daily for eight weeks, with control at 4 (T1 ) and eight weeks (T2 ). Any other concomitant treatment (both topical and/or systemic) was avoided during study period. Improvement was observed in both Sartorius score grading system and inflammatory and noninflammatory lesion counts. The novel lotion has proved to be effective and well-tolerated topical agent alone or in association with other topical and/or systemic tratments in HS, without side effects.

Interferon-γ release assay for tuberculosis in patients with psoriasis treated with tumour necrosis factor antagonists: in vivo and in vitro analysis.

BACKGROUND: Screening for latent tuberculosis infection (LTBI) is mandatory in patients with psoriasis prior to starting on tumour necrosis factor (TNF) blockers. OBJECTIVES: To investigate the longitudinal changes of interferon (IFN)-γ response to Mycobacterium tuberculosis-specific antigens by serial QuantiFERON-TB Gold In-Tube (QFT-GIT) testing in patients with psoriasis during long-term anti-TNF therapy. The direct in vitro effect of adalimumab on IFN-γ secretion was also evaluated. METHODS: In total, 148 patients with psoriasis designated to start anti-TNF treatment were enrolled. We performed a tuberculin skin test at screening, and QFT-GIT at baseline and serially for 24 months after TNF antagonist onset. RESULTS: At screening, QFT-GIT was positive in 22.3% of the patients, negative in 73.6% and indeterminate in 4%. The IFN-γ response following isoniazid therapy declined and became QFT-GIT negative in 8% of 26 patients with LTBI; in 69% of subjects with LTBI the QFT-GIT remained persistently positive with a significant increase of IFN-γ levels during the follow-up, even if no cases of active tuberculosis were found. Variations of IFN-γ levels were observed also in 7% of 27 patients without LTBI who switched to positive QFT-GIT after 12 or 18 months of biologic therapy, suggesting a new occurrence or reactivation of LTBI. In vitro data showed that in the presence of adalimumab the IFN-γ levels were significantly reduced in a dose-dependent manner (P < 0.05). CONCLUSIONS: Fluctuations of IFN-γ release may occur in patients with psoriasis treated with TNF antagonists. The clinical use of repeated blood tests and the correct interpretation of individual IFN-γ changes could be useful in identifying possible cases of LTBI reactivation or newly acquired tuberculosis infection during long-term anti-TNF treatment.

Efficacy of food supplement to improve metabolic syndrome parameters in patients affected by moderate to severe psoriasis during anti-TNFα treatment.

AIM: Psoriasis is a systemic inflammatory immune-mediated skin disease. Recently a relationship with metabolic syndrome in terms of psoriasis severity and response to therapy was observed. METHODS: We performed an open-label randomized controlled study to evaluate the role of a nutraceutical containing Q10 coenzyme, Krill-oil, lipoic acid, resveratrol, Vitis vinifera seed oil, vitamin E and selenium in addition to etanercept therapy for patients affected by psoriasis and metabolic syndrome. Forty patients were enrolled and divided into two arms, one receiving only etanercept, one other receiving also the neutraceutical. After a period of 3 months (T1) a second evaluation of the considered parameters was performed. RESULTS: At T1 statistically significant differences were detected in HDL cholesterol and triglycerides values both comparing the two arms and in the nutraceutical arm. CONCLUSION: Our results show that the dietary addiction of the nutraceutical to the etanercept therapy in patients affected by both psoriasis and metabolic syndrome could help to restore the normal lipid profile.

Evaluation of QuantiFERON-TB Gold In-Tube in human immunodeficiency virus infection and in patient candidates for anti-tumour necrosis factor-alpha treatment.

SETTING: Cross-sectional study at four out-patient clinics in a single referral centre in Italy. OBJECTIVE: To evaluate the performance of QuantiFERON-TB Gold In-Tube (QFT-GIT) in human immunodeficiency virus (HIV) infected adults and in patients with immune-mediated inflammatory diseases (IMIDs) who are candidates for anti-tumour necrosis factor-alpha (TNF-alpha) treatment. DESIGN: A total of 402 immunocompromised patients were enrolled, including 207 HIV-infected individuals and 195 IMID patients scheduled for anti-TNF-alpha treatment. Tuberculin skin test (TST) and QFT-GIT were performed. For active tuberculosis (TB), test results were compared with microbiological, histopathological and clinical diagnoses. RESULTS: In HIV-infected patients, the level of agreement between the tests was 68% and QFT-GIT sensitivity was 66% (95%CI 47-82). We found a large proportion of indeterminate QFT-GIT results (33.4%), which correlated with CD4 count < 200 cells/microl (P < 0.0001). The degree of agreement with TST was higher in IMID patients (81.6%). Factors associated with discordant positive TST and negative QFT-GIT results were bacille Calmette-Guérin vaccination (P = 0.0001), previous TB (P = 0.0001) and agricultural work (P = 0.0005). CONCLUSION: The performance of QFT-GIT varies between different types of immunocompromised patients. Interferon-gamma release assays should not be used to confirm or rule out a diagnosis of active TB in HIV-infected adults. As there were no cases of active TB in the IMID subgroup, it was difficult to determine which test performs better in this population.

Morpheaform extra-ocular sebaceous carcinoma.

BACKGROUND: Sebaceous carcinoma is an unusual, aggressive, malignant tumor derived from the epithelium of sebaceous glands. It may arise in ocular or extra-ocular sites and is often evident as an ulcerated or non-ulcerated cystic nodule measuring up to 8 cm in diameter. A significant number of extra-ocular sebaceous carcinomas have been associated with metastases and high mortality rate. METHODS AND RESULTS: We reviewed the literature in the context of our report of a 68-year-old woman who had a morpheaform plaque of the upper lip of 15 years duration, extending into the left naso-genal groove, which histologically also showed marked stromal fibrosis. Three years after excision, there were no signs of recurrence or metastases. CONCLUSIONS: This patient is unusual in clinical and histologic pattern, as a morpheaform appearance has only been described previously in only one sebaceous carcinoma. In addition, no metastatic disease 15 years after tumor onset is a fortunate and remarkable feature.
