Impact of Anti-CD4 Autoantibodies on Immune Reconstitution in People With Advanced Human Immunodeficiency Virus.

Background: Despite suppressive antiretroviral therapy (ART), 15%-30% of people with human immunodeficiency virus (HIV) experience a limited recovery of CD4 T cells. Although autoantibodies against the CD4 receptor have previously been identified in people with HIV (PWH), little is known about their longitudinal impact on CD4 T-cell reconstitution.

Methods: Anti-CD4 autoantibodies were evaluated by the fluid-phase luciferase immunoprecipitation systems immunoassay in ART-naive people with advanced HIV (CD4 count ≤100 cells/µL), PWH with CD4 count >200 cells/µL, long-term nonprogressors, people with idiopathic CD4 lymphopenia, people with autoimmune lymphoproliferative syndrome, and healthy volunteers without HIV.

Aspirin modulates generation of procoagulant phospholipids in cardiovascular disease, by regulating LPCAT3.

Enzymatically oxygenated phospholipids (eoxPL) from lipoxygenases (LOX) or cyclooxygenase (COX) are prothrombotic. Their generation in arterial disease, and their modulation by cardiovascular therapies is unknown. Furthermore, the Lands cycle acyl-transferases that catalyze their formation are unidentified.

Characteristics and outcomes of adults with acute brain injuries admitted to intensive care units in Australia and New Zealand from 2013 to 2022.

Background: The characteristics and outcomes of patients with acute brain injuries admitted to the intensive care unit (ICU) in Australia and New Zealand (ANZ) are insufficiently described.

Objective: This study aimed to describe the epidemiology of acute brain injury in ICU patients in ANZ.

Methods: A binational retrospective cohort study was conducted using the ANZ Intensive Care Society Adult Patient Database.

Perplexing paradoxical reactions: navigating the complexity of protracted tuberculosis meningitis-a case report.

Tuberculous meningitis (TBM) has considerable mortality and morbidity, and it often presents therapeutic challenges when complicated by paradoxical reactions (PRs). Here, the clinical course of four cases of TBM patients complicated by PRs in a longitudinal TB cohort is described while also providing insights from the larger clinical cohort. Research flow cytometry, biomarker analysis, and drug concentrations were performed on available samples.
