Serum Antinuclear Antibody Correlated in Hispanic Pediatric Patients With NFLD

Non-alcoholic fatty liver disease (NAFLD), also known as metabolic (dysfunction) associated fatty liver disease (MAFLD), is excessive fat build-up in the liver without another clear cause such as alcohol use. Obesity and type 2 diabetes are strong risk factors for NAFLD. More...

Pediatric Antiphospholipid Syndrome Diagnosis Methods Reassessed

Antiphospholipid syndrome (APS) is a systemic autoimmune disease characterized by thrombotic events and/or pregnancy morbidity in the setting of persistently positive antiphospholipid antibodies (aPL). More...

Double-Antigen Sandwich ELISA Detects Antibodies to Trypanosoma cruzi

Chagas disease (CD), also known as American trypanosomiasis, is a potentially life-threatening vector-borne tropical zoonosis caused by the protozoan parasite Trypanosoma cruzi. The estimated prevalence of CD in 21 Latin American countries where it is considered endemic exceeds five million individuals; CD accounts for approximately 7,500 deaths annually. More...

Flow Cytometric Immunophenotyping Assessed for Classic Hodgkin Lymphoma

The diagnosis of classic Hodgkin lymphoma (CHL) requires morphologic and immunophenotypic identification of neoplastic Hodgkin and Reed-Sternberg cells (collectively referred to as HRS cells) intermixed with a background of reactive lymphocytes, histiocytes, plasma cells, and eosinophils. More...

Biomarker Panel for Risk of Early Respiratory Failure Following Hematopoietic Cell Transplantation

Allogeneic hematopoietic cell transplantation (HCT) is a life-saving therapy used for malignant and nonmalignant diseases. However, post-HCT pulmonary complications continue to be a significant problem. When severe, pulmonary complications can result in respiratory failure (RF), affecting 10% to 23% of patients. More...

Serum Extracellular Vesicle Arginase 1 Measured In T2DM

Serum extracellular vesicle (EV)-derived arginase 1 (ARG 1) plays a critical role in diabetes-associated endothelial dysfunction. This study was performed to determine the levels of serum EV-derived ARG 1 in T2DM and non-T2DM participants and to examine the association of serum EV-derived ARG 1 with T2DM incidence. More...

Enzyme Immunoassays Developed for Serodiagnosis of Human Leptospirosis

The laborious microscopic agglutination test (MAT) is the gold standard serologic test for laboratory diagnosis of leptospirosis. We developed EIA based serologic assays using recombinant proteins (rLigA, rLigB, rLipL32) and whole-cell extracts from eight Leptospira serovars as antigen and assessed the diagnostic performance of the new assay.
