RT Journal Article T1 Potential association of plasma lysophosphatidic acid (LPA) species with cognitive impairment in abstinent alcohol use disorders outpatients A1 García Marchena, Nuria A1 Pizarro, Nieves A1 Martínez Huélamos, Miriam A1 Pavón Carrasco, Francisco Javier A1 Requena-Ocaña, Nerea A1 Araos, Pedro A1 Silva-Peña, Daniel A1 Suárez, Juan A1 Santín, Luis Javier A1 de la Torre, Rafael A1 Serrano, Antonia A1 Flores-López, María A1 Rodríguez De Fonseca, Fernando Antonio AB Lysophosphatidic acid (LPA) species are bioactive lipids participating in neurodevelopmental processes. The aim was to investigate whether the relevant species of LPA were associated with clinical features of alcohol addiction. A total of 55 abstinent alcohol use disorder (AUD) patients were compared with 34 age/sex/body mass index-matched controls. Concentrations of total LPA and 16:0-LPA, 18:0-LPA, 18:1-LPA, 18:2-LPA and 20:4-LPA species were quantifed and correlated with neuroplasticity-associated growth factors including brain derived neurotrophic factor (BDNF), insulinlike growth factor-1 (IGF-1) and IGF-2, and neurotrophin-3 (NT-3). AUD patients showed dysexecutive syndrome (22.4%) and memory impairment (32.6%). Total LPA, 16:0-LPA, 18:0-LPA and 18:1-LPA concentrations, were decreased in the AUD group compared to control group. Total LPA, 16:0-LPA, 18:2-LPA and 20:4-LPA concentrations were decreased in men compared to women. Frontal lobe functions correlated with plasma LPA species. Alcohol-cognitive impairments could be related with the deregulation of the LPA species, especially in 16:0-LPA, 18:1-LPA and 20:4-LPA. Concentrations of BDNF correlated with total LPA, 18:2-LPA and 20:4-LPA species. The relation between LPA species and BDNF is interesting in plasticity and neurogenesis functions, their involvement in AUD might serve as a biomarker of cognitive impairment.
