Las consecuencias hemodinámicas de la translocación bacteriana (BT) en la enfermedad hepática crónica avanzada son conocidos. La BT desencadena la activación del sistema inmunológico y conduce a una respuesta inflamatoria sostenida. Las citoquinas proinflamatorias promueven un empeoramiento de las ...  Ver más
The hemodynamic consequences of bacterial translocation (BT) in advanced chronic liver disease are examined, and knowed. BT triggers the activation of the immune system and leads to a sustained inflammatory response. Proinflammatory cytokines exacerbate hemodynamic alterations in cirrhosis, especially at the hepatic, cardiovascular, and renal levels. The contribution of type I natural killer T cells (iNKTs) to chronic liver disease remains unknown. Hypothesis CD1d-mediated activation of type I natural killer T cells (iNKTs) with glycolipid antigens from intestinal bacteria predicts increased cardiac output and poor prognosis in patients with advanced chronic liver disease. Objectives Main Objective: To characterize iNKT levels in peripheral blood of cirrhotic patients. Detect circulating iNKTs and their subtypes (iNKT1, iNKT2, iNKT10, iNKT17). Analyze proinflammatory cytokines secreted by different iNKT subtypes: IFN-ɣ, IL-4, IL-10, IL-17. Secondary Objectives: Detect bacterial translocation (BT) in serum and subgroup patients according to BT+/BT-. Determine if there are statistically significant differences in the number of iNKTs in BT- cirrhotic patients compared to BT+. Do they have fewer iNKTs? Do they present a different microbiota or immunological profile? Methodology An experimental study will be conducted using whole blood samples from cirrhotic patients at the Hospital General de Alicante. The abundance of each iNKT subtype will be analyzed using flow cytometry, and proinflammatory cytokines secreted will be analyzed using ELISA (IFN-ɣ, IL-4, IL-10, IL-17). Statistical analyses will be performed using the R bioinformatics software.
