Febrile seizures (FSs) are the most common convulsive event in children. Inflammatory elements and genetics have major roles in their pathogenesis. As of the importance of interleukin-6 (IL-6) in FS, this study was performed to assess IL6 single nucleotide polymorphisms (SNPs) in a group of patients with FS. IL6 gene (-174 and +565) SNPs were studied on genomic DNAs of 90 children with FS, using PCR-SSP method. The results were compared to 139 healthy individuals. The presence of the G allele or the GG genotype at +565 position reduced risk of FS, while the A allele at +565 position of the promoter regions was a constituted risk factor for developing FS. This study could support the idea that IL6 SNPs play a role in the pathogenesis of FS.

Rheumatoid arthritis (RA) is a systemic, chronic autoimmune disease. Many studies have shown that microorganisms may be an important pathological factor leading to the onset of RA. Some infectious or non-infectious pathogenic microorganisms and their metabolites may be the initiating factors of the early onset of RA.

Background: The emergence of new molecular targeted drugs marks a breakthrough in asthma treatment, particularly for severe cases. Yet, options for moderate-to-severe asthma treatment remain limited, highlighting the urgent need for novel therapeutic drug targets. In this study, we aimed to identify new treatment targets for asthma using the Mendelian randomization method and large-scale genome-wide association data (GWAS).

Evaluation of Plasma Neurodegenerative Biomarkers for Diagnosing Minimal Hepatic Encephalopathy and Predicting Overt Hepatic Encephalopathy in Chinese Patients with Hepatic Cirrhosis.

Department of Infectious Diseases, Tongji Hospital, Tongji Medical College and State Key Laboratory for Diagnosis and Treatment of Severe Zoonotic Infectious Diseases, Huazhong University of Science and Technology, Wuhan, Hubei, China.

Background And Aims: The performance of neurodegenerative biomarkers-neurofilament light chain (NfL), glial fibrillary acidic protein (GFAP), tau, and ubiquitin carboxy-terminal hydrolase L1 (UCHL1)-in diagnosing minimal hepatic encephalopathy (MHE) has not been systematically evaluated, simultaneously, nor have their associations with the development of overt hepatic encephalopathy (OHE). This study aimed to evaluate the performance of plasma NfL, GFAP, tau, and UCHL1 in diagnosing MHE and predicting the development of OHE in Chinese patients with hepatic cirrhosis.

Methods: In this prospective study, 124 patients with hepatic cirrhosis were recruited.

Importance: Aging is accompanied by immune dysregulation, which has been implicated in Alzheimer's disease (AD) pathogenesis. Individuals who are genetically predisposed to elevated levels of proinflammatory mediators might be at increased risk for AD.

Objective: To investigate whether genetic propensity for higher circulating levels of interleukin 6 (IL-6) is associated with AD risk.
