VEXAS syndrome, is a hemato-inflammatory chronic disease characterized with predominantly rheumatic and hematologic systemic involvement. It was first described in 2020 by group of researchers the United States. syndrome rare condition that primarily affects adult males caused mutation UBA1 gene located on X chromosome. Its pathogenesis related to somatic affecting methionine-41 (p.Met41) UBA1, major E1 enzyme initiates ubiquitylation. Mutant lead decreased ubiquitination activated innate immune pathways inflammation occur. The specific mechanism which leads clinical features not yet fully understood. newly define adult-onset inflammatory manifested treatment-refractory fevers, arthritis, chondritis, vasculitis, cytopenias, typical vacuoles hematopetic precursor cells, neutrophilic cutaneous pulmonary inflammation. Diagnosing can be challenging due its rarity overlap symptoms other conditions. Genetic testing identify essential for definitive diagnosis. Currently, there no known cure treatment mainly focuses managing symptoms. This may involve use anti-inflammatory medications, immunosuppressive drugs, supportive therapies tailored individual patient's needs. Due recent discovery ongoing research being conducted better understand pathogenesis, features, potential options. In this review article, clinical, diagnostic approaches were evaluated light latest literature data.

Bladder urothelial carcinoma (BLCA) is the 10th most common cancer with a low survival rate and strong male bias. We studied field cancerization in BLCA using multi-sample- multi-tissue-per-patient protocol for sensitive detection of autosomal post-zygotic chromosomal alterations loss chromosome Y (LOY). analysed 277 samples histologically normal urothelium, 145 tumors 63 blood from 52 males 15 females, in-house adapted Mosaic Chromosomal Alterations (MoChA) pipeline. This approach allows identification early aberrations urothelium patients. Overall, 45% patients exhibited at least one alteration sample. Recurrence analysis resulted 16 hotspots composed either gains copy number neutral heterozygosity (CN-LOH) or deletions CN-LOH, encompassing well-known new driver genes. Conservative assessment LOY showed 29%, 27% 18% LOY-cells tumors, respectively. provide proof principle that our can characterize earliest preconditioning to development.

Clonal hematopoiesis (CH) is an age-associated phenomenon leading to increased risk of both hematologic malignancy and nonmalignant organ dysfunction. Increasingly available genetic testing has made the incidental discovery CH clinically common yet evidence-based guidelines effective management strategies prevent adverse health outcomes are lacking. To address this gap, prospective CHIVE (clonal inflammation in vasculature) registry biorepository was created identify monitor individuals at risk, support multidisciplinary clinics, refine taxonomy standards practice for mitigation. Data from first 181 patients enrolled recapitulate molecular epidemiology biobank-scale retrospective studies, with DNMT3A, TET2, ASXL1, TP53 as most commonly mutated genes. Blood counts across all hematopoietic lineages trended lower CH. In addition, had higher rates end dysfunction, particular chronic kidney disease. Among CH, variant allele frequency independently associated presence cytopenias progression malignancy, whereas other high-risk clone features were not clear. Notably, accumulation multiple distinct also progression, supporting a recently published score. Surprisingly, ∼30% clinics adjudicated having clonal indeterminate potential, highlighting need purpose-built assays field.

Abstract Hematopoietic stem cell transplantation (HCT) represents a curative treatment option for certain malignant and nonmalignant hematological diseases. Conditioning regimens before HCT, the development of graft-versus-host disease (GVHD) in allogeneic setting, delayed immune reconstitution contribute to early late complications by inducing tissue damage or humoral alterations. Hemostasis and/or complement system are biological regulatory defense systems involving cellular reactions variably involved these after HCT. The hemostasis have multiple interactions, which been described both under physiological pathological conditions. They share common targets, such as endothelium, suggests interactions pathogenesis several serious phase Complications interfere with each other thus include transplant-associated thrombotic microangiopathy (HSCT-TMA), sinusoidal obstruction syndrome/veno-occlusive (SOS/VOD), GVHD. Here, we review current knowledge on changes HCT how may define clinical impact.
