: Janus kinase (JAK) inhibitors have expanded the therapeutic options for moderate-to-severe atopic dermatitis (AD). The possibility of dose modulation with abrocitinib (100 and 200 mg) and upadacitinib (15 and 30 mg), both selective JAK1 inhibitors, represents a potential clinical advantage, allowing dose escalation in cases of insufficient response and dose de-escalation in the setting of poor tolerability or during maintenance treatment. However, real-world data remain limited, and the rationale for dose adjustment is not always standardized. This study aimed to describe, using a real-world database, the frequency, timing, and reasons for dose modifications of these agents. : We retrospectively analyzed the clinical data of 212 patients with moderate-to-severe AD treated with abrocitinib (n = 47) or upadacitinib (n = 165). Dose adjustments, including dose escalation and dose de-escalation, were recorded together with their timing and clinical reasons. : In the abrocitinib group, 34/47 patients (72.3%) initiated treatment at 100 mg, whereas 13/47 patients (27.7%) started at 200 mg. Six patients (12.8%) underwent a dose adjustment. One patient (2.1%) switched from 200 to 100 mg because of complete AD remission and concomitant menstrual cycle alterations, whereas five patients (10.6%) underwent dose escalation from 100 to 200 mg because of incomplete disease control. Among the six abrocitinib-treated patients who underwent dose adjustment, achievement of IGA 0/1 after dose modification was documented in all cases. In the upadacitinib group, 93/165 patients (56.4%) started at 15 mg, whereas 72/165 patients (43.6%) started at 30 mg. Overall, 44/165 patients (26.7%) underwent at least one dose adjustment, accounting for a total of 50 dose modifications: 27 escalations from 15 to 30 mg and 23 de-escalations from 30 to 15 mg. Among patients initiating treatment at 15 mg, 23/93 patients (24.7%) increased the dose to 30 mg after a median of 33.1 weeks because of suboptimal disease control. Among those starting at 30 mg, 21/72 patients (29.2%) reduced the dose to 15 mg after a median of 44.3 weeks. Of these, 12/21 patients (57.1%) reduced the dose because of adverse events, including herpetic infections and acne, whereas the remaining patients de-escalated because of optimal disease control. Some patients underwent multiple dose modifications: four followed a 30→15→30 mg sequence, with re-escalation after 13.2 weeks because of suboptimal disease control, and two followed a 15→30→15 mg sequence, with dose reduction after approximately 26.7 weeks because of herpes zoster. Overall, 29/44 patients achieved IGA 0/1 within 16 weeks and 38/44 within 32 weeks after dose modification. : In this real-world cohort, dose adjustments of selective JAK1 inhibitors were frequently performed in patients with moderate-to-severe AD, particularly among those treated with upadacitinib. Dose escalation was mainly used to address suboptimal disease control, whereas dose de-escalation was performed in the setting of adverse events or optimal disease control. The availability of two dosing regimens may allow treatment intensity to be adapted to individual disease severity, response, and tolerability, supporting a personalized approach to AD management.

Background and Objectives: Oral Janus kinase (JAK) inhibitors have become an important therapeutic class in dermatology, with approved indications including atopic dermatitis and alopecia areata. Owing to their broad immunomodulatory effects and rapid onset of action, these agents are increasingly used off label for a variety of inflammatory skin disorders that are often refractory to standard therapies. The objective of this review was to provide a comprehensive overview of the published literature on the off-label dermatologic use of oral JAK inhibitors, summarizing clinical outcomes, safety profiles and treatment durations reported in real-world settings. Materials and Methods: A literature search was conducted in PubMed to identify case reports and case series describing off-label dermatologic use of baricitinib, abrocitinib, upadacitinib, and ritlecitinib. Extracted data included authorship and year, article type, treatment regimen, treatment duration and follow-up, prior systemic therapies, clinical outcomes, and reported adverse events. Results: A total of 136 articles were included, comprising 45 articles on abrocitinib (63 patients), 55 on upadacitinib (94 patients), 35 on baricitinib (45 patients), and 2 on ritlecitinib (2 patients). Across a wide spectrum of dermatological conditions, oral JAK inhibitors showed consistent clinical efficacy. Responses were frequently rapid and disease control was often maintained over several months of treatment. In many cases, dose reduction or treatment discontinuation did not lead to immediate relapse. Overall tolerability was favorable, with adverse events reported in a minority of patients and predominantly described as mild and transient. Conclusions: Although our data is limited to case-based literature, this review highlights the broad off-label therapeutic potential of oral JAK inhibitors in dermatology. Their rapid onset of action, sustained clinical responses, frequent maintenance of remission after dose tapering or discontinuation and generally acceptable safety profile support their consideration as treatment options in selected patients.

Background: Transthyretin cardiac amyloidosis (ATTR-CM) is an infiltrative cardiomyopathy that frequently progresses to symptomatic heart failure (HF), often with mildly reduced or reduced ejection fraction (EF). Standard therapies are limited in NYHA III–IV, and Tafamidis is approved only for the early stages. Cardiac contractility modulation (CCM) therapy has shown promise in HF with reduced EF, but its role in ATTR-CM remains unexplored. Methods: This multicentric, prospective pilot study evaluated the safety and efficacy of CCM therapy in ten patients (n = 10) with ATTR-CM, EF between 25 and 45%, and NYHA class III–IV symptoms refractory to optimal medical therapy. All patients underwent implantation of the Optimizer CCM system and were followed for at least 12 months. The primary endpoint was the incidence of worsening heart failure (WHF); secondary endpoints included changes in EF, NYHA class, 6-minute walk test (6MWT), and quality of life metrics. Results: In this cohort (n = 10), CCM therapy significantly reduced WHF episodes (from 0.18 ± 0.09 to 0.025 ± 0.08 hospitalizations/patient-year, p < 0.001) and improved NYHA class and 6MWT (p < 0.001). EF increased by an average of 4.8 ± 6.1%, and 6MWT improved by 31.3 ± 53.3%. Importantly, all patients became eligible for Tafamidis after CCM therapy due to improved functional status. Conclusion: This pilot study suggests that CCM therapy is a feasible and potentially effective option for ATTR-CM patients with advanced HF who are not candidates for existing disease-modifying treatments. These findings support the rationale for larger studies, including the ongoing AMY-CCM registry (NCT05167799), to validate CCM’s therapeutic role in this population.

Prurigo nodularis (PN) is a chronic dermatological condition characterized by intensely pruritic nodules resulting from repeated scratching. Its pathogenesis involves neuroimmune dysregulation, inflammatory cytokines, and neural proliferation. Conventional treatments often provide limited relief, necessitating novel therapeutic approaches. This narrative review explores emerging biologics and small molecules for PN treatment, assessing their mechanisms, efficacy, and safety. A comprehensive literature search was conducted using PubMed, Google Scholar, and Web of Science for relevant studies up to February 2025. Additionally, ongoing clinical trials were identified through a verified international website. The search terms included “prurigo nodularis”, “biologic treatments”, “monoclonal antibodies”, “small molecules”, and “JAK inhibitors”. Among new treatment options, dupilumab, an IL-4 receptor antagonist, and nemolizumab, an IL-31 receptor inhibitor, demonstrated significant efficacy in reducing pruritus and lesion severity in PN patients. Other promising monoclonal antibodies include vixarelimab (OSMRβ inhibitor) and barzolvolimab (KIT inhibitor). Small molecules such as JAK inhibitors (upadacitinib, povorcitinib) also show potential by modulating inflammatory pathways. Clinical trials highlight their efficacy, safety, and long-term benefits. Emerging biologics and small molecules represent a transformative approach for PN management, offering targeted therapies that address underlying immunological and neurological mechanisms. Ongoing research and long-term studies are crucial to optimizing treatment strategies and improving patient outcomes.

Background: Genetic testing in hypertrophic cardiomyopathy (HCM) yields variable positivity rates. Identifying clinical predictors of positive genetic tests could improve pre-test counseling and refine expectations about diagnostic yield. Methods: We analyzed consecutive genotyped HCM probands from a contemporary multicenter cohort across four Italian tertiary centers. Genotype positivity was defined as the presence of ≥1 pathogenic or likely pathogenic variant (ACMG classes 4–5). Multivariable logistic regression identified predictors of genotype positivity. Sensitivity analyses assessed the incremental value of left atrial volume index (LAVI) ≥ 34 mL/m2 and the mode of first clinical presentation. Results: Among 274 genotyped probands (median age at diagnosis 54 years; 62% male), 86 (31%) were genotype-positive (38% MYBPC3, 29% MYH7). Age at diagnosis <40 years (OR 2.38, 95%CI 1.26–4.51, p = 0.008), family history of sudden cardiac death/major ventricular arrhythmias (OR 2.34, 95%CI 1.16–4.84, p = 0.019) and family history of non-ischemic cardiomyopathy (OR 1.92, 95%CI 1.04–3.54, p = 0.038), were independently associated with genotype positivity whereas arterial hypertension was inversely associated (OR 0.42, 95%CI 0.23–0.77). Maximal left ventricular wall thickness > 20 mm and gender were not predictive of genotype positivity. Inclusion of LAVI modestly improved the model performance (AUC 0.769, p = 0.016, ΔAUC +0.024; DeLong p = 0.016) but without leading to meaningful patient reclassification. Conclusions: Genotype positivity in HCM links to earlier onset and family history; traditional severity markers and initial presentation may not independently suggest genetic causality. These findings may help shape a personalized approach to genetic counseling in HCM.

Cardiomyopathies have evolved from being considered rare and idiopathic to being increasingly linked to genetic factors. This shift was enabled by advancements in understanding genetic variants and the widespread use of next generation sequencing (NGS). Current guidelines emphasize the importance of evidence-based gene panels that can offer “clinically actionable results”, which provide diagnostic and prognostic insights. They also advise against indiscriminate family screening after finding variants of uncertain significance (VUS) and recommend collaboration among multidisciplinary teams for an accurate variant pathogenicity assessment. This article presents an innovative “cardiogenetic clinic” approach involving cardiologists and medical geneticists to provide genetic testing and family screening. This study attempts to improve the diagnostic process for suspected genetic cardiomyopathies; this includes direct patient recruitment during cardiology appointments, NGS analysis, and combined consultations with cardiologists and geneticists to assess the results and screen the families. The study cohort of 170 patients underwent genetic testing, which identified 78 gene variants. Positive results (C4 or C5 variants) occurred in 20 (19.8%) cases, with rates varying by cardiomyopathy phenotype, while 57 (73.1%) of the variants found were classified as C3-VUS, causing a significant management issue. This model shortened the time to results, increased patient adherence, and improved patients’ diagnoses. Family screening was pondered depending on the relevance of the detected variants, showing this method’s potential to impact patient management.

Background and Objectives: Janus kinase inhibitors (JAKi) have significantly advanced the treatment of various dermatological conditions by modulating the JAK-STAT signalling pathway. While these inhibitors have proven effective, they also pose challenges due to associated increase in serum lipid levels and relative potential cardiovascular risks. This perspective work aims to discuss the implications of these lipid alterations proposing management strategies for patients with dermatological disorders under JAKi treatments. Materials and Methods: This manuscript reviews existing and recent literature on the metabolic effects of JAKi, particularly focusing on their impact on lipid profiles in patients treated for dermatological diseases. Results: JAK inhibitors are consistently associated with an increase in both LDL and HDL levels shortly after treatment initiation, which tend to stabilise over time. Despite these changes, there is no clear evidence linking these alterations to an increased risk of major adverse cardiovascular events (MACE), indicating a complex interaction between lipid metabolism and JAK-STAT signalling. Conclusions: Although JAKi may induce lipid changes in patients, raising concerns, especially in ones with existing cardiovascular risks, currently there is no proven link to increased MACE in this population. Monitoring lipid levels, alongside lifestyle modifications and possible statin use, can manage these effects without the need to stopping treatment.

Cardiac alterations are frequently observed after acute neurological disorders. Takotsubo syndrome (TTS) represents an acute heart failure syndrome and is increasingly recognized as part of the spectrum of cardiac complications observed after neurological disorders. A systematic investigation of TTS patients with neurological disorders has not been conducted yet. The aim of the study was to expand insights regarding neurological disease entities triggering TTS and to investigate the clinical profile and outcomes of TTS patients after primary neurological disorders. The International Takotsubo Registry is an observational multicenter collaborative effort of 45 centers in 14 countries (ClinicalTrials.gov, identifier NCT01947621). All patients in the registry fulfilled International Takotsubo Diagnostic Criteria. For the present study, patients were included if complete information on acute neurological disorders were available. 2402 patients in whom complete information on acute neurological status were available were analyzed. In 161 patients (6.7%) an acute neurological disorder was identified as the preceding triggering factor. The most common neurological disorders were seizures, intracranial hemorrhage, and ischemic stroke. Time from neurological symptoms to TTS diagnosis was ≤ 2 days in 87.3% of cases. TTS patients with neurological disorders were younger, had a lower female predominance, fewer cardiac symptoms, lower left ventricular ejection fraction, and higher levels of cardiac biomarkers. TTS patients with neurological disorders had a 3.2-fold increased odds of in-hospital mortality compared to TTS patients without neurological disorders. In this large-scale study, 1 out of 15 TTS patients had an acute neurological condition as the underlying triggering factor. Our data emphasize that a wide spectrum of neurological diseases ranging from benign to life-threatening encompass TTS. The high rates of adverse events highlight the need for clinical awareness.

Very elderly population constitutes an increasingly larger proportion of patients admitted for acute coronary syndromes (ACS). Notably, age represents both a proxy of frailty and an exclusion criterion in clinical randomized trials, which probably contributes to lack of data and undertreatment of real-world elderly patients. The aim of the study is to describe patterns of treatment and outcome of very elderly patients with ACS. All consecutive patients aged ≥ 80 years old (yo) admitted between January 2017 and December 2019 with ACS were included. The primary endpoint was in-hospital occurrence of major adverse cardiovascular events (MACE), defined as the composite of cardiovascular death, new onset cardiogenic shock, definite/probable stent thrombosis, and ischemic stroke. The secondary endpoints were in-hospital incidence of Thrombolysis in Myocardial Infarction (TIMI) major/minor bleedings, contrast-induced nephropathy (CIN), six-month all-cause mortality, and unplanned readmission. One hundred ninety-three patients (mean age 84.1 ± 3.5 yo, 46% females) were included, of whom 86 (44.6%), 79 (40.9%), and 28 (14.5%) presented with ST elevation myocardial infarction (STEMI), non-ST elevation myocardial infarction (NSTEMI), and unstable angina (UA), respectively. The vast majority of patients received an invasive strategy, with 92.7% undergoing coronary angiography and 84.4% to percutaneous coronary intervention (PCI). Aspirin was administered to 180 (93.3%) patients, clopidogrel to 89 (46.1%) patients, and ticagrelor to 85 (44%) patients. In-hospital MACE occurred in 29 patients (15.0%), whereas 3 (1.6%) and 12 patients (7.2%) experienced in-hospital TIMI major and TIMI minor bleeding, respectively. Of the overall population, 177 (91.7%) were discharged alive. After discharge, 11 patients (6.2%) died of all-cause death, whereas 42 patients (23.7%) required a new hospitalization within six months. Invasive strategy of ACS in elderly patients seems safe and effective. Six-month new hospitalization appears inevitably related to age.

Background: Atopic dermatitis (AD) is a chronic pruritic inflammatory disease affecting children and adults. Upadacitinib and abrocitinib are selective Janus kinase 1 inhibitors approved for the treatment of moderate-to-severe AD. Although their efficacy and safety are described in phase 3 clinical trials, real-world data are limited. Objectives: We aimed to evaluate the effectiveness and safety of upadacitinib and abrocitinib treatment in a real-life adult population with moderate-to-severe AD throughout an extended observation period. Methods: This retrospective observational study was conducted by analyzing data from the electronic records of IRCCS Humanitas Research Hospital from January 2023 to December 2024. Patients were administered either upadacitinib (15 or 30 mg) or abrocitinib (100 or 200 mg). Effectiveness was evaluated by using clinician-reported scores (Investigator Global Assessment [IGA] and Eczema Area and Severity Index [EASI]) and patient-reported outcomes (peak pruritus numerical rating scale [PP-NRS]) at weeks 8, 16, 32 and 52. Statistical significance was set at a probability value (p-value) < 0.05. Adverse events were also collected. Results: In total, 129 patients were included in the study, and 84 of them reached 52 weeks. At week 52, the EASI 75, 90, and 100 responses were 88.9%, 70.8%, and 54.2% for upadacitinib, and 100%, 91.7%, and 75% for abrocitinib. An IGA score equal to 0 or 1 at 52 weeks was achieved by 84.7% of patients treated with upadacitinib and 100% of those receiving abrocitinib. A four-point reduction from baseline PP-NRS was reported by 86.1% for upadacitinib and by 83.3% of patients for abrocitinib after one year of follow-up. Conclusions: Our study showed comparable or even higher effectiveness outcomes in terms of EASI 75, EASI 90, and EASI 100 at week 52 compared to phase-3 clinical trials, with no new safety concerns, supporting the real-world effectiveness of abrocitinib and upadacitinib in moderate-to-severe AD.
