Abstract
BACKGROUND Ulcerative colitis (UC) is an inflammatory bowel disease characterized by chronic inflammation of the gastrointestinal tract, affecting millions of individuals throughout the world, and producing an impaired health-related quality of life. Granulocyte and monocyte apheresis (GMA) is a therapeutic option for UC management to induce remission by selective removal of activated leukocytes from bloodstream. Despite the knowledge of the important role of epigenetics in UC pathogenesis, and in the response to different treatments, nothing is known about the role of microRNAs in GMA therapy in UC patients. METHODS Seven consecutively UC patients who started GMA in combo therapy with infliximab were recruited. Peripheral blood samples were taken before the apheresis session, at the start of the induction (S0) and at the end (S10). They were follow-up during the induction phase (10 sessions: 2 sessions for a week during 3 wk and 1 session for a week during 4 wk) of the treatment at a tertiary hospital (Hospital la Fe) and 6 mo after finishing the GMA induction therapy. MiRNA was extracted and analyzed by RT-PCR. R software and GraphPad were used. RESULTS Clinical disease activity significantly decreased after induction therapy with GMA (median partial Mayo score 2 (IQR, 1-6) (P < .05). Fecal calprotectin value and CRP value significantly decreased after induction therapy. Five microRNAs modified their expression during GMA (unsupervised analysis): miR-342-3p, miR-215-5p, miR-376c-3p, miR-139-5p, and miR-150-5p. When a sub-analysis was performed in those patients who showed good response to apheresis treatment (n = 5), two microRNAs showed to be implicated: miR-215-5p and miR-365a-3p. These are preliminary but promising and novel results, as it is the first time, to our knowledge that microRNA profiles have been studied in the context of GMA treatment for IBD.

Kanekura T. Clinical and immunological effects of adsorptive myeloid lineage leukocyte apheresis in patients with immune disorders. J Dermatol 2018; 45:943-950. [PMID: 29782055 DOI: 10.1111/1346-8138.14471] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/13/2018] [Accepted: 04/13/2018] [Indexed: 01/18/2023]
Abstract
Adsorptive granulocyte and monocyte apheresis (GMA) with the Adacolumn® is an extracorporeal treatment, which uses cellulose acetate (CA) beads as adsorptive leukocytapheresis carriers designed to remove elevated and potentially activated myeloid lineage leukocytes. Reports on the clinical efficacy of GMA in patients with skin lesions have appeared in the published work. Dermatological diseases, which are known to respond to GMA, include pyoderma gangrenosum, skin lesions of Behçet's disease, rheumatoid arthritis, pustular psoriasis, psoriatic arthritis, adult-onset Still's disease, Sweet's syndrome, cutaneous allergic vasculitis and systemic lupus erythematosus rashes. In association with clinical studies, efforts to understand the mechanisms of GMA have made significant progress. GMA selectively depletes elevated myeloid lineage leukocytes through binding between blood immunoglobulin G or complement iC3b, which form on the surface of CA beads and the Fcγ receptors or complement receptors expressed on the myeloid lineage cells. However, GMA has immunomodulatory effects including down-modulation of inflammatory cytokine profile, changes in leukocyte surface receptors and induction of regulatory T cells. These actions render GMA a unique non-pharmacological treatment option for patients with chronic dermatoid conditions, which are difficult to treat with pharmacological preparations.
