Treatment of very high risk membranous nephropathy complicated by pulmonary embolism with glucocorticoids and rituximab: Case report.
Medicine (Baltimore)
January 2025
Division of Nephrology, Department of Medicine, National University Hospital, Singapore.
Rationale: We report the efficacy of combination prednisolone and intravenous (IV) rituximab as an immunosuppressive regimen for a young male presenting with extensive venous thromboembolism including a submassive pulmonary embolism secondary to life-threatening nephrotic syndrome from very high risk anti-phospholipase-A2 receptor (PLA2R) positive membranous nephropathy. Initial treatment was with mechanical thrombectomy and anticoagulation. Thereafter, oral prednisolone was initiated to induce remission, during a period of uninterrupted anticoagulation.

Elucidating the interaction between membrane proteins and antibodies requires whole-cell imaging at high spatiotemporal resolution. Lattice light-sheet (LLS) microscopy offers fast volumetric imaging but suffers from limited spatial resolution. DNA-based point accumulation for imaging in nanoscale topography (DNA-PAINT) achieves molecular resolution but is restricted to two-dimensional imaging owing to long acquisition times.

Article Synopsis
- This study tested rituximab (RTX) on patients with primary membranous nephropathy (PMN) who were dependent on calmodulin inhibitors (CNIs) and not fully in remission.
- Among 36 patients, those who were drug-dependent showed a significant reduction in proteinuria and improved remission rates after 12 months of RTX therapy, with complete remission increasing from 10% to 70%.
- The results indicated that RTX not only helped patients overcome CNI dependency but also led to significant immunological improvements while minimizing the risks of adverse effects.
[Clinical Analysis of 25 Cases of Acquired Hemophilia A in a Single Center].

Department of Hematology, The Second Hospital of Hebei Medical University, Hebei Key Laboratory of Hematology, Shijiazhuang 050000, Hebei Province, China.
Objective: To explore the diagnosis and treatment of acquired hemophilia A (AHA) based on the analysis of clinical data.
Methods: A retrospective analysis was conducted on the clinical manifestations, laboratory characteristics, treatment, and outcomes of 25 patients diagnosed with AHA who were admitted to the Second Hospital of Hebei Medical University.
Results: Among all patients, 11 cases had secondary factors, including 5 cases of autoimmune diseases, 3 cases of pregnancy-related disease, 1 case of pemphigoid, 1 case of Graves' disease, and 1 case of monoclonal gammaglobulinemia of unknown significance (MGUS).
Enhancing complement activation by therapeutic anti-tumor antibodies: Mechanisms, strategies, and engineering approaches.
Semin Immunol

Department of Immunology, Leiden University Medical Center, Leiden, Netherlands. Electronic address:
The complement system plays an integral role in both innate and adaptive immune responses. Beyond its protective function against infections, complement is also known to influence tumor immunity, where its activation can either promote tumor progression or mediate tumor cell destruction, depending on the context. One such context can be provided by antibodies, with their inherent capacity to activate the classical complement pathway.
