Risk of injury associated with the sedative potential of second‐generation antihistamines: A nationwide retrospective cohort study

British Journal of Clinical Pharmacology, EarlyView.
Abstract Aim Individual second‐generation antihistamines may possess differential sedative potential due to the variability in central histamine receptor H1 occupancy. This study aimed to evaluate whether the sedative potential of second‐generation antihistamines is associated with the risk of injury during Japan's pollen season. Methods We conducted a

Segmental Hair Analysis of Diphenhydramine and Cyclizine Following a Single Dose

Drug Testing and Analysis, EarlyView.
A single oral dose of diphenhydramine and cyclizine can be quantified in human head hair for a minimum of 5 months and, in certain cases, for up to 1 year following intake. Among 12 study participants, the measured concentrations ranged from 0 to 610 pg/mg within 1 year post‐intake.

Absence seizures: Update on signaling mechanisms and networks

Epilepsia Open, EarlyView.
Abstract Absence seizures (AS) are a hallmark of genetic generalized epilepsies (GGE), characterized by brief episodes of impaired consciousness accompanied by electroencephalographic spike‐and‐wave discharges (SWDs). Traditionally attributed to cortico‐thalamo‐cortical (CTC) dysrhythmia, emerging evidence suggests a more intricate pathophysiological ...

Histamine Regulates the Inflammatory Profile of SOD1-G93A Microglia and the Histaminergic System Is Dysregulated in Amyotrophic Lateral Sclerosis

Frontiers in Immunology, 2017
Amyotrophic lateral sclerosis (ALS) is a late-onset motor neuron disease where activated glia release pro-inflammatory cytokines that trigger a vicious cycle of neurodegeneration in the absence of resolution of inflammation.

Histamine induced high mobility group box-1 release from vascular endothelial cells through H1 receptor

Frontiers in Immunology, 2022
BackgroundSystemic allergic reaction is characterized by vasodilation and vascular leakage, which causes a rapid, precipitous and sustained decrease in arterial blood pressure with a concomitant decrease of cardiac output.

Osteoarthritis: An Immuno‐Inflammatory Disease‐Mechanisms of Immune Cell Dysregulation and Potential Therapeutic Strategies

Med Research, EarlyView.
This review summarizes the immuno‐inflammatory mechanisms driving the pathogenesis of osteoarthritis (OA), extending beyond the traditional view of OA as a purely degenerative disease to incorporate immune cell infiltration, inflammatory factor release, and the formation of a chronic low‐grade inflammatory microenvironment.

Renal histamine H1 and H2 receptors: characterization and functional significance

, 1978
Canine experiments were designed to determine if both histamine H1 and H2 receptors are present in the renal circulation. Renal blood flow (RBF) increased steeply over the first minute of intra-arterial histamine infusion, then increased gradually to a ...
