Biomarkers for the Molecular Diagnosis of IgE-Mediated Hymenoptera Venom Allergy in Clinical Practice.
Int J Mol Sci
December 2024
Faculty of Medicine, Department of Clinical Immunology, Wroclaw Medical University, 51-616 Wroclaw, Poland.
Hymenoptera venom allergy (HVA) is a potentially life-threatening condition, making accurate diagnosis crucial for identifying significant IgE sensitizations and enabling effective venom immunotherapy. In this review, we provide a detailed overview of biomarkers for the molecular diagnosis of IgE-mediated hypersensitivity to Hymenoptera insect venoms in clinical practice, and we present, in a structured manner, their importance in differentiating genuine sensitizations versus cross-sensitizations using different diagnostic procedures. Updated algorithms are provided, along with the advantages and limitations of molecular diagnosis approaches.

Department of Laboratory Medicine, the Second Affiliated Hospital, Chongqing Medical University, Chongqing, 400010, P.R. China.
Background: Enterobacter cloacae is increasingly prevalent and resistant to multiple antibiotics, making it a significant pathogen in healthcare settings with high mortality rates. However, its pathogenic mechanisms are not fully understood.
Results: In this study, we explored the role of nagZ in regulating the virulence of E.
Cellular and Humoral Response After Induction of Protection and After Finishing Venom Immunotherapy.
Biomolecules
November 2024
Laboratory for Clinical Immunology and Molecular Genetics, University Clinic of Respiratory and Allergic Diseases Golnik, 4204 Golnik, Slovenia.
venom allergy (HVA) is an IgE-mediated hypersensitivity reaction caused by species stings (honeybee, vespid, or ant). The only effective treatment is venom immunotherapy (VIT). Our study aimed to evaluate whether humoral and cellular biomarkers measured before, during, and after honeybee VIT are associated with the success of VIT, which was assessed by the response to a sting challenge one year after finishing VIT.

Ann Clin Microbiol Antimicrob
January 2025
Department of Clinical Laboratory, Xiangya Hospital, Central South University, 87 Xiangya Road, Changsha, 410008, Hunan, China.
Background: The emergence of colistin resistance in carbapenem-resistant Klebsiella pneumoniae (CRKP) is a significant public health concern, as colistin has been the last resort for treating such infections. This study aimed to investigate the prevalence and molecular characteristics of colistin-resistant CRKP isolates in Central South China.
Methods: CRKP isolates from twelve hospitals in Central South China were screened for colistin resistance using broth microdilution.
Role of extracellular vesicles in the pathogenesis of mosquito-borne flaviviruses that impact public health.
J Biomed Sci

Departamento de Biología Molecular y Biotecnología, Instituto de Investigaciones Biomédicas, Universidad Nacional Autónoma de México (UNAM), 04510, Mexico City, Mexico.
Mosquito-borne flaviviruses represent a public health challenge due to the high-rate endemic infections, severe clinical outcomes, and the potential risk of emerging global outbreaks. Flavivirus disease pathogenesis converges on cellular factors from vectors and hosts, and their interactions are still unclear. Exosomes and microparticles are extracellular vesicles released from cells that mediate the intercellular communication necessary for maintaining homeostasis; however, they have been shown to be involved in disease establishment and progression.
