Abstract Objectives To evaluate the effectiveness and safety of current treatment strategies for vacuoles, E1 enzyme, X-linked, autoinflammatory, somatic (VEXAS) syndrome. Methods A protocolized systematic review according to Preferred Reporting Items Systematic Reviews Meta-Analyses (PRISMA) guidelines was performed. Three databases were searched reports on VEXAS. Data from included publications extracted a narrative synthesis Treatment response recorded as complete (CR), partial (PR) or none (NR) depending changes in clinical symptoms laboratory parameters. Patient characteristics, data previous treatments analysed. Results We identified 36 with total 116 patients; 113 (98.3%) male. The azacytidine (CR 9/36, 25%; PR 14/36, 38.9%), Janus kinase inhibitors (JAKi) 11/33, 33%; 9/33, 27.3%), tocilizumab 3/15, 20%; 6/15, 40%), allogeneic stem cell transplantation 6/7, 85.7%; one patient died), anakinra 4/5, 80%; NR 1/5, 20%), canakinumab 1/2, 50%; 50%) glucocorticoid monotherapy 1/6, 16.7%; 4/6, 66.7%). Individual available TNF inhibitors, rituximab MTX. adverse events 67 patients (67/116, 57.8%) included: pneumonia (12/67, 17.9%), other infections (9/67, 13.4%), venous thromboembolisms (6/67, 8.9%), cytopenias (4/67, 5.9%), acute 5.9%) chronic graft-vs-host-disease (2/67, 2.9%). Conclusion Current VEXAS are limited inhomogeneous. decisions should be individualized. For devolvement algorithms trials needed. Adverse remain challenge, especially an elevated risk thromboembolism associated JAKi carefully considered.

Autoimmune manifestations in VEXAS: Opportunities for integration and pitfalls to interpretation

Journal of Allergy and Clinical Immunology, Год журнала: 2023, Номер 151(5), С. 1204 - 1214

Опубликована: Март 21, 2023

VEXAS (Vacuoles, E1 enzyme, X-linked, Autoinflammatory, Somatic) is a novel entity manifesting with multiplicity of clinical features. Somatic mutations the UBA1 gene in hematopoietic stem cells constitute genetic basis VEXAS. As an X-linked disorder, most cases occur men, classically developing symptoms during fifth to sixth decade life. Considering its multidisciplinary nature involving numerous branches internal medicine, has elicited wide medical interest and several conditions have been associated this disease. Even so, recognition everyday practice not necessarily straightforward. Close collaboration between different specialists mandatory. Patients may manifest range features from manageable cytopenias disabling life-threatening autoimmune phenomena limited responses therapy, potential for progression hematological malignancies. Diagnostic treatment guidelines are exploratory include rheumatological supportive care treatments. Allogeneic cell transplantation potentially curative, but risks significant position algorithm yet be defined. Herein, we present variegated manifestations VEXAS, provide criteria diagnostic testing UBA1, discuss options, including allogeneic transplantation, current evidence, future directions.

VEXAS syndrome: complete molecular remission after hypomethylating therapy

Annals of Hematology, Год журнала: 2024, Номер 103(3), С. 993 - 997

Опубликована: Янв. 12, 2024

Abstract The VEXAS syndrome, a genetically defined autoimmune disease, associated with various hematological neoplasms has been attracting growing attention since its initial description in 2020. While therapeutic strategies have explored case studies, the optimal treatment strategy is still under investigation and allogeneic cell transplantation considered only curative treatment. Here, we describe 2 patients who achieved complete molecular remission of underlying UBA1 mutant clone outside context HCT. Both received hypomethylating agent azacitidine, deep triggered de-escalation even cessation sustained one them. Prospective studies are necessary to clarify which will benefit most from therapy understand variability response different strategies.

Importance VEXAS (vacuoles, E1 enzyme, X-linked, autoinflammatory, somatic) syndrome is a newly defined genetic disease with an estimated prevalence of 1 in 4269 men older than 50 years and marked by systemic inflammation, progressive bone marrow failure, inflammatory cutaneous manifestations. Objective To define the spectrum manifestations association these findings clinical, genetic, histological features. Design, Setting, Participants This observational cohort study included data from 112 patients who were diagnosed VEXAS-defining variants UBA1 between 2019 2023. Data collected medical record review or directly evaluated at National Institutes Health Bethesda, Maryland. Main Outcomes Measures histological, other clinical findings. A secondary outcome was response to treatment VEXAS. Results Among (median [range] age, 69 [39-79] years; 111 [99%] male), skin involvement common (93 [83%]), most frequent presenting feature (68 [61%]). Of 64 histopathologic reports available 60 patients, predominant leukocytoclastic vasculitis (23 [36%]), neutrophilic dermatosis (22 [34%]), perivascular dermatitis (19 [30%]). Distinct pathogenic associated specific The p.Met41Leu variant frequently dermal infiltrates (14 17 [82%]), often resembling histiocytoid Sweet syndrome. In contrast, p.Met41Val vasculitic lesions (11 20 [55%]) mixed leukocytic infiltrate (17 [85%]). Oral prednisone improved 67 73 (92%). Patients treated anakinra developed severe injection-site reactions (12 16 [75%]), including ulceration (2 12 [17%]) abscess formation (1 [8%]). Conclusions Relevance this show that are early manifestation Genetic evaluation for should be considered male vasculitis, dermatoses, chondritis.

Clinical features and treatments of VEXAS syndrome in critical care: a scoping review

Critical Care, Год журнала: 2025, Номер 29(1)

Опубликована: Апрель 17, 2025

Abstract Background Vacuoles, E1 enzyme, X-linked, autoinflammatory, somatic (VEXAS) syndrome is a recently discovered severe disorder that predominantly affects adult males, characterized by systemic inflammation and hematologic abnormalities. Despite its profound impact on patient outcomes, awareness of VEXAS among critical care providers remains severely limited, often leading to delayed recognition, diagnosis, initiation appropriate treatment. This study aims address this knowledge gap conducting scoping review in the setting. Methods followed PRISMA-ScR guidelines Joanna Briggs Institute methodology, analyzing data from Cochrane CENTRAL, MEDLINE via PubMed, EMBASE, Web Science May 19, 2024. We included studies reported clinical features treatments patients with requiring care. Results Of 1262 reports identified, 78 met inclusion criteria, including 45 case reports/series, 17 observational studies, 15 reviews, one systematic review. Analysis 55 cases revealed median age 69 strong male predominance (54/55). ICU admission rates ranged 28 33%, mortality between 18 40%. Critical manifestations shock, hemophagocytic lymphohistiocytosis, acute respiratory distress syndrome, thrombosis, airway edema. Sepsis was cause death, other causes related organ failure, cardiovascular events, intestinal perforation. Treatment approaches combined conventional measures immunosuppressive immunomodulatory therapies, although infectious complications were frequently reported. Conclusion lack systematically analyzed focusing setting, suggesting significant understanding characteristics optimal for syndrome. Further research focused setting essential improve early develop standardized treatment protocols, ultimately outcomes complex population.

Abstract VEXAS is a prototypic hemato‐inflammatory disease combining rheumatologic and hematologic disorders in molecularly defined nosological entity. In this nationwide study, we aimed at screenshotting the current diagnostic capabilities clinical‐genomic features of VEXAS, tracked UBA1 longitudinal clonal dynamics upon different therapeutics, including allogeneic hematopoietic cell transplant. We leveraged collaboration between Italian Society Experimental Hematology Rheumatology disseminated national survey to collect clinical molecular patient information. Overall, 13/29 centers performed genomic testing locally, Sanger sequencing (46%), next‐generation (23%), droplet digital polymerase chain reaction (8%), or combination (23%). A total 41 male patients were identified, majority (51%) with threonine substitutions Met41 hotspot, followed by valine leucine (27% 8%). Median age diagnosis was 67 years. All displayed anemia (median hemoglobin 9.1 g/dL), macrocytosis. Bone marrow vacuoles observed most cases (89%).
