ABSTRACT

INTRODUCTION: Ixekizumab proved to be effective and safe for psoriasis treatment in several randomized clinical trials and real-life studies. Nevertheless, long-term real-world experiences are still lacking, with little data up to 4 years of treatment. OBJECTIVES: To analyse survival, effectiveness and safety of ixekizumab in a real-life cohort of patients affected by moderate-to-severe psoriasis or psoriatic arthritis up to 260 weeks (5 years). METHODS: We included all patients treated with ixekizumab from December 2017 to March 2021. Drug survival (DS) was analysed in patients at risk for up to 5 years. Cox analysis was adopted to evaluate possible predictive factors of discontinuation. Psoriasis Area Severity Index (meanPASI and PASI100, 90, and ≤3) was used as outcomes of effectiveness on observed patients at 16, 52, 104, 156, 208 and 260 weeks. Logistic regression was performed to identify possible predictive factors of response. RESULTS: DS was 65.5% at 260 weeks, with being a super-responder patient (achievement of PASI100 at 16 weeks and maintained at 28 weeks) correlated with less risk of discontinuation. PASI100, 90 and ≤3 was achieved by 54.1%, 60.5% and 73% of observed patients, respectively, at 16 weeks, and by 59.1%, 81.8% and 95.5%, respectively, at 260 weeks. High mean BMI was the only factor strongly associated with less achievement of the outcomes at the earlier time points: PASI100 at 16 weeks (OR 0.93, CI 0.87-0.98, p = 0.014) and at 104 weeks (OR 0.91, CI 0.84-0.98, p = 0.019), PASI90 achievement at 16 weeks (OR 0.94, CI 0.88-0.99, p = 0.028) and 104 weeks (OR 0.91, CI 0.83-0.99, p = 0.027), and PASI ≤3 (OR 0.86, CI 0.76-0.97, p = 0.018) at 104 weeks. No severe adverse events were observed. CONCLUSIONS: Ixekizumab showed high effectiveness and safety for up to 5 years, with survival of 2/3 of treated patients. Rapid response to treatment is predictive of long-term response.

ABSTRACT

BACKGROUND: Many national guidelines at the European level recommend first-line therapy based on the anti-TNF-alpha adalimumab for treatment of psoriasis and psoriatic arthritis, mainly for economic reasons. Consequently, patients being treated with newer IL-17 and IL-23 inhibitors underwent previous unsuccessful first-line adalimumab-based therapy. OBJECTIVES: Evaluate the efficacy and safety of IL-17 and IL-23 inhibitors after treatment with adalimumab compared to adalimumab-naive psoriatic patients. METHODS: We retrospectively analysed 1053 psoriatic patients treated with anti-IL17 and anti-IL23 agents, which included 68 and 24 adalimumab-experienced and 399 and 260 bio-naive patients. Efficacy was assessed with mean PASI, PASI90, PASI100, and <3. RESULTS: Concerning the achieving of PASI100, PASI90 and PASI < 3 in patients treated with anti-IL17 agents, no significant differences were observed between adalimumab-experienced and bio-naive patients. In patients treated with an anti-IL-23 agent, a faster response was observed in bio-naive patients, with PASI < 3 significantly higher than ADA-experienced patients at 16 weeks (77% vs. 58% p = 0.048). In a sub-analysis that evaluated the performance of anti-IL17 and anti-IL23 agents in adalimumab-experienced patients with a history of secondary failure, no significant differences were found. In multivariate analysis of PASI100, only anti-IL-17 therapy appeared to have a negative impact at 52 weeks (OR: 0.54 p = 0.04) independently of previous treatment. For PASI90, type of treatment and bio-naïve status did not seem to have an impact at any time point. CONCLUSIONS: Anti-IL 23 and anti-IL 17 agents are not significantly different in terms of efficacy in bio-naive patients or as second-line therapy after failure with a biosimilar or originator adalimumab.

ABSTRACT

BACKGROUND: Limited data are available on risk factors associated with lichen sclerosus and no data are available on gender differences in genital lichen sclerosus (GLS). OBJECTIVE: This multicentre study aimed at identifying potential risk factors for GLS, through data collection from a large, mixed-sex sample of patients comparing gender-related differences in relation to data from the general population. METHODS: This was a cross-sectional study on 729 subjects (53.8% females, 46.2% males) affected with GLS, consecutively observed within a network of 15 Italian dermatology units. The following information was collected: demographic data, anthropometric measures, comorbidities, family history of LS, clinical features and symptoms related to GLS. RESULTS: Overweight and obesity, blood hypertension, hypothyroidism and an educational attainment equal or above upper secondary school level were more frequent among the study patients than among the general Italian population. Moreover, a family history of GLS was reported more frequently than expected among GLS patients. These factors were similar in males and females. The disease tended to occur later in females than in males. CONCLUSIONS: Our findings suggest that metabolic factors, and possibly a sedentary lifestyle, may play a role in GLS pathogenesis in genetically predisposed patients, and that risk profile is similar in males and females despite some difference in the onset of symptoms.

ABSTRACT

BACKGROUND: Development of more than one primary melanoma in a sole patient is frequent, accounting for 1.2-8.2% of melanoma patients in most recent series. OBJECTIVE AND METHODS: Clinical, histological and epidemiological characteristics of 270 multiple primary melanomas patients were reviewed. RESULTS: Two-hundred and seven patients (76.7%) had two melanomas, whereas in the remaining 63 the number of primary ranged from three to eight; on the whole, 639 multiple primary melanomas were identified. Synchronous melanomas developed more frequently in patients with three or more lesions; median age was significantly lower in the group of patients with more than three melanomas than in the others. Mean Breslow's thickness significantly decreases (P<0.001) from the first (1.77±1.76 mm) to subsequent primaries (0.85±1.25 mm for the second and 0.66±0.48 mm for the third melanoma). Percentage of 'in situ' melanomas was 5.6% as first diagnosis, but increased to 24.8% for the second melanoma; number of nodular melanomas was significantly lower for succeeding diagnosis. AJCC stage at diagnosis showed a statistical prognostic significance, whereas outcome and survival did not depend on the number of primary lesions. Multivariate analysis confirmed the prognostic role of Breslow's thickness, ulceration, gender and patient age, and the better prognosis of patients with multiple melanomas, respect to those with single primary melanoma. CONCLUSIONS: Skin examination and long-term follow-up are mandatory for patients affected by melanoma, with the intent to promptly diagnose not only a disease progression but also possible new primary melanomas.

ABSTRACT

BACKGROUND: Primary cutaneous T-cell lymphomas (CTCLs) are a heterogeneous group of lymphomas where the tumour population emerges within a multiple subclone pattern. Mycosis fungoides (MF) and Sézary syndrome (SS) are characterized by the expansion of clonal CD4+/CD45RO+ memory T cells. Lymphomatoid papulosis (LyP) is a chronic, lymphoproliferative disorder included in the CD30+ primary CTCL spectrum. Several studies have suggested a role of viral infection for super-antigenic activation of T lymphocytes; however, evidence of their association with CTCLs is still lacking. Human herpesvirus (HHV) 7 is a CD4+ T-lymphotropic herpesvirus; its restricted cellular tropism and the ability to induce cytokine production in infected cells could make it an important pathogenic cofactor in lymphoproliferative disorders. OBJECTIVES: To investigate the presence of HHV7 DNA on CTCL and healthy skin donors (HD). METHODS: We used quantitative real time polymerase chain reaction to evaluate the potential pathogenic role of HHV7. RESULTS: Twenty-seven of 84 (32.1%) HD were positive for HHV7 DNA. Twenty-one of 148 (14.2%) patients with CTCLs were positive for HHV7 DNA: nine of 39 (23.1%) SS, six of 14 (42.9%) CD30+ CTCLs and six of 24 (25.0%) LyP, and HHV7 DNA was negative in all 71 patients with MF. CONCLUSIONS: These results seem to exclude a pathogenic role of HHV7 in CTCLs, suggesting the possibility of skin as a latency site.

ABSTRACT

Personality data obtained from 78 medical students at the University of Turin were analysed using the Eysenck Personality Inventory, a 69-question psychometric test which evaluates levels of extroversion, neuroticism and psychoticism. Results were analysed by standard deviation and controlled with Student's test. With regard to extroversion, a contrast was found between aspiring surgeons and gynecologists who tended to be extroverts, and aspiring psychiatrists who tended to be introverts. A similar contrast was also found between two groups in terms of psychotism: aspiring surgeons tended to be less psychotic and aspiring pediatricians tended to be more psychotic. In conclusion, it is possible to hypothesise that the personality traits influence, in synergy with other factors, the choice of medical specialisation.
