Introduction: . Idiosyncratic adverse drug reactions (IADRs) or drug hypersensitivity reactions (DHRs) represent a major health problem because they are unpredictable and can be severe with potential life-long or even lethal consequences. Their pathophysiology is not clear but thought to be immune mediated supported by the significant statistical association of these reactions with specific alleles of the () gene.
Area Covered: This comprehensive update review summarizes the currently available evidence on the role of gene locus in IADRs and discusses the present understanding of the pathophysiology of IADRs. We searched the available literature in PubMed and Google Scholar with no date restriction for publications on and adverse drug reactions. Findings are summarized and discussed in the context of the currently available evidence.
Expert Opinion: The role of the immune system in IADRs and the role of pharmacogenetic testing in this field is evident. genetic testing is a very promising in the management of these reaction. Many obstacles seem to prevent pharmacogenetic testing to meet its full potential including cost and healthcare providers education. Further work in needed to provide more evidence and allow widespread use of pharmacogenetic testing in the clinical practice.

Background: Abelacimab is a fully human monoclonal antibody that binds to the inactive form of factor XI and blocks its activation. The safety of abelacimab as compared with a direct oral anticoagulant in patients with atrial fibrillation is unknown.
Methods: Patients with atrial fibrillation and a moderate-to-high risk of stroke were randomly assigned, in a 1:1:1 ratio, to receive subcutaneous injection of abelacimab (150 mg or 90 mg once monthly) administered in a blinded fashion or oral rivaroxaban (20 mg once daily) administered in an open-label fashion.
Intraoperative Tranexamic Acid Infusion Reduces Perioperative Blood Loss in Pediatric Limb-Salvage Surgeries: A Double-Blinded Randomized Placebo-Controlled Trial.
J Bone Joint Surg Am
January 2025
National Cancer Institute, Cairo University, Giza, Egypt.
Background: Limb-salvage surgery for malignant bone tumors can be associated with considerable perioperative blood loss. The aim of this randomized controlled trial was to assess the safety and efficacy of the intraoperative infusion of tranexamic acid (TXA) in children and adolescents undergoing limb-salvage surgery.
Methods: All participants were <18 years of age at the time of surgery and diagnosed with a malignant bone tumor of the femur that was treated with resection and reconstruction with a megaprosthesis.
Tularemia in a Psoriasis Patient on Biologic Therapy After Relocation to Western South Dakota.

Department of Internal Medicine, University of South Dakota Sanford School of Medicine.
Background: Francisella tularensis is an aerobic, gram negative coccobacillus bacterium that causes tularemia. F. tularensis spreads primarily through ticks, biting flies, droplet inhalation, contaminated mud or water, or infected animal bites, and it can survive in animal carcasses with the most common mode of transmission occurring via inoculation into the skin and inhalation/ingestion.

Sodium-glucose co-transporter 2 inhibitors, such as enavogliflozin, offer promising metabolic benefits for patients with type 2 diabetes (T2D), including glycemic control and improved cardiac function. Despite the clinical evidence, real-world evidence is needed to validate their safety and effectiveness. This study aims to evaluate the effects of weight loss and safety of enavogliflozin administration in patients with T2D in a real-world clinical setting over 24 weeks.

Pfizer Ltd., Tadworth, United Kingdom.
Background: Risk factors and comorbidities can complicate management of non-valvular atrial fibrillation. We describe and compare real-world safety and effectiveness of direct oral anticoagulants (DOACs; apixaban, rivaroxaban, dabigatran) and vitamin K antagonists (VKAs) in subgroups of patients with non-valvular atrial fibrillation at high risk for gastrointestinal (GI) bleeding, utilizing data from a national quasi-exhaustive French database.
Methods: Anticoagulant-naïve adults with non-valvular atrial fibrillation with ≥1 gastrointestinal bleeding risk factor, initiating anticoagulant treatment January 2016-December 2019, and covered by the French national health data system were eligible.
