Insights on treatment of adult ITP: algorithm for management and role of multimodal therapy.

Hematology Am Soc Hematol Educ Program

The management of immune thrombocytopenia (ITP) is continuously evolving with the development and introduction of newer therapies and a better understanding of the disease. Corticosteroids still represent the cornerstone of first-line treatment. Patients who fail to achieve remission with a short course of corticosteroids require subsequent therapy.

Key Clinical Message: The coexistence of rheumatoid arthritis (RA) and PLA2R-associated membranous nephropathy (MN) is uncommon. It is difficult to demonstrate whether the mechanisms of renal pathology are triggered by RA, but it has been observed that the pro-inflammatory molecules present in RA increase the expression of PLA2R. Rituximab could be effective in both conditions.

Complement-dependent cytotoxicity (CDC) is a primary mechanism-of-action of monoclonal antibody (mAb) immunotherapies used to treat haematological cancers, including rituximab and daratumumab. However, mAb efficacy may be limited by reduced bioavailability of complement C1q - which activates the complement classical pathway following interactions with mAb-opsonised target cells. C1q is secreted by phagocytes upon recruitment to sites of muscle damage to facilitate muscular repair, hence we hypothesised that muscle damaging exercise may increase C1q 'spill-over' into blood.

Article Synopsis
  • Bendamustine-rituximab (BR) therapy shows effectiveness in treating elderly patients with diffuse large B-cell lymphoma (DLBCL), especially when other treatments are unsuitable.
  • The study investigates the mechanisms of BR therapy through various methods, including RNA sequencing and Crispr technology, revealing that BR not only kills tumor cells by causing apoptosis but also activates the immune system via the cGAS-STING pathway.
  • The findings indicate that BR creates an inflammatory tumor environment, suggesting that combining BR with other therapies could enhance treatment outcomes for patients with DLBCL.

Optimizing Anti-Myelin-Associated Glycoprotein and IgM-Gammopathy Testing for Neuropathy Treatment Evaluation.

Neurology

December 2024

From the Department of Neurology (C.J.K., D.D., M.V.P., M.P.S., G.S., M.L.M.), Mayo Clinic, Rochester, MN; Department of Neurology (J.D.T.), Royal Adelaide Hospital, Adelaide, South Australia; Department of Laboratory Medicine and Pathology Mayo Clinic (D.L.M., J.R.M., S.S.), Rochester, MN; Department of Neurology (S.S.), Rambam Medical Center, Haifa, Israel; and Department of Hematology Mayo Clinic Foundation (S.M.A.), Rochester, MN.

Background And Objectives: Patients with typical anti-myelin-associated glycoprotein (anti-MAG) neuropathy have IgM-gammopathy, mimic distal chronic inflammatory demyelinating polyradiculoneuropathy (CIDP), and are treatment resistant. Anti-MAG patients go unrecognized when IgM-gammopathy is undetected or with atypical phenotypes. We investigated an optimal anti-MAG titration cutoff for excluding CIDP and the impact of IgM-gammopathy detection on neuropathy treatment evaluation without anti-MAG antibodies.
