Azacitidine can be effective in myelodysplastic syndromes (MDS) associated with inflammatory/autoimmune diseases. Vacuoles, E1 Enzyme, X-linked, Autoinflammatory, Somatic syndrome (VEXAS) is a new monogenic autoinflammatory syndrome caused by somatic ubiquitin-like modifier-activating enzyme 1 (UBA1) mutation, often associated with MDS, whose treatment is difficult and not yet codified. Based on a French nationwide registry of 116 patients with VEXAS, we report the efficacy and safety of azacitidine treatment in 11 patients with VEXAS with MDS. Clinical response of VEXAS to azacitidine was achieved in five patients (46%), during 6, 8+, 12, 21, 27+ months respectively, suggesting that azacitidine can be effective in selected patients with VEXAS and associated MDS.

Infections are increasingly recognised as a major cause of morbidity and mortality in patients with vacuoles, E1 enzyme, X-linked, autoinflammatory, somatic (VEXAS) syndrome. We conducted a systematic review to characterise the infectious burden of VEXAS syndrome and propose preventive strategies. We included 57 studies (813 patients) showing that infections in patients with VEXAS syndrome were frequent, severe in 40-60% of cases, and fatal in 6-15% of cases.

Background: VEXAS syndrome (Vacuoles, E1 enzyme, X-linked, Autoinflammatory, Somatic) is a recently identified autoinflammatory disorder caused by somatic UBA1 mutations. It presents with intractable systemic inflammation and hematologic abnormalities. Diagnostic delay and limited therapeutic consensus pose challenges in clinical practice.

VEXAS syndrome (Vacuoles, E1-enzyme, X-linked, Autoinflammation, and Somatic) is a recently identified late-onset autoinflammatory disorder characterized by a unique interplay between hematological and inflammatory manifestations. It results from somatic mutations in the gene, located on the short arm of the X chromosome. Initially, females were considered mere carriers, with the syndrome primarily affecting males over 50.

Purpose Of Review: This review aims to explore the relationship between autoinflammatory diseases (AIDs) and vasculitis, with a focus on recently identified syndromes and newly published data since 2016.
Recent Findings: While the connection between innate immune dysregulation and systemic inflammation is well established in AIDs, the occurrence of vasculitis in these disorders remains underrecognized and often misclassified.We discuss vasculitic manifestations in a wide range of AIDs, including familial Mediterranean fever, DADA2, HA20, VEXAS, CAPS, TRAPS, HIDS/MKD, Blau syndrome, and others.

VEXAS syndrome (vacuoles, E1 enzyme, X-linked, autoinflammatory, and somatic) is a recently identified clonal disorder caused by somatic UBA1 mutations in hematopoietic stem cells, leading to bone marrow failure (BMF) and systemic inflammation. We screened 1771 patients with BMF who underwent unrelated hematopoietic cell transplantation in Japan between 1995 and 2020 using multitarget real-time PCR. The diagnoses included myelodysplastic syndrome (MDS, n = 1139), myeloproliferative neoplasms (n = 125), plasma cell neoplasms (n = 23), acquired BMF (n = 395), and congenital BMF (n = 89).
