Biomarkers.

Background: Glial fibrillary acidic protein (GFAP) is a putative blood biomarker for Alzheimer's disease (AD). Most studies measure plasma GFAP (pGFAP) utilizing the Single Molecule Array (Simoa) platform or other high-cost platforms. However, we aim to validate the value of GFAP as a blood biomarker for AD using chemiluminescent microparticle immunoassay (CMIA), an ubiquitous lower-cost platform.

Risk factors of death or chronic renal replacement therapy requirements in patients with thrombotic microangiopathies without ADAMTS-13 deficiency.

Thrombotic microangiopathy (TMA), characterized by microangiopathic hemolytic anemia, thrombocytopenia, and multisystem organ dysfunction, is a life-threatening disease. Patients with TMA who do not exhibit a severe ADAMTS-13 deficiency (defined as a disintegrin-like and metalloprotease with thrombospondin type 1 motif no. 13 activity ≥10%: TMA-13n) continue to experience elevated mortality rates.
