Proton pump inhibitors (PPIs) are among the most widely used drugs worldwide. However, their influence on the progression of end-stage kidney disease (ESKD) in established chronic kidney disease (CKD) cases is unclear. Using the Korean Health Insurance Review and Assessment database encoded by the Observational Medical Outcomes Partnership-Common Data Model (OMOP-CDM), patients with stage 3 or 4 CKD initiating PPIs or histamine-2 receptor antagonists (H2RAs) for over 90 days were enrolled from 2012 through 2021.

Stimulation of histamine H-receptors produces a positive inotropic effect in the human atrium.

There is a controversy whether histamine H-receptor activation raises or lowers or does not affect contractility in the human heart. Therefore, we studied stimulation of H-receptors in isolated electrically stimulated (one beat per second) human atrial preparations (HAP). For comparison, we measured force of contraction in left atrial preparations (LA) from mice with overexpression of the histamine H-receptor in the heart (H-TG).

Histamine H2 Receptor Antagonists in the Treatment and Prevention of Heart Failure.

Int J Gen Med

December 2024

Department of Critical Care Medicine, Chengdu First People's Hospital, Chengdu, People's Republic of China.

Despite advancements in the treatment of heart failure (HF) and modest improvements in survival rates over the past few decades, mortality rate remains significantly high. HF not only imposes a significant economic burden on patients' families but also presents a substantial challenge to society at large. Therefore, effective treatment and prevention strategies are crucial.

Objective: To investigate whether cardiac mast cells (MCs) participate in pressure overload-induced myocardial hypertrophy through the regulation of transient receptor potential vanilloid 4 (TRPV4).

Methods: Pressure overload-induced myocardial hypertrophy was induced via abdominal aortic constriction (AAC). Myocardial hypertrophy was evaluated by measuring the heart weight index (HW/BW), lung weight index (LW/BW), ratio of heart weight to tibia length (HW/TL), ratio of lung weight to tibia length (LW/TL), and cross-sectional area of myocardial cells.

Background: The introduction of epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) has revolutionized advanced non-small cell lung cancer (NSCLC) treatment. However, their efficacy can be compromised by concurrent use of gastric acid suppressants (GASs), such as proton pump inhibitors (PPIs) and histamine 2 receptor antagonists (H2RAs). This study aimed to update the evidence on the impact of GASs on the overall survival (OS) and progression-free survival (PFS) in patients on EGFR-TKI treatment.
