Excessive alcohol consumption is a major health and social issue in our society. Pharmacologic administration of the endocrine hormone fibroblast growth factor 21 (FGF21) suppresses alcohol consumption through actions in the brain in rodents, and genome-wide association studies have identified single nucleotide polymorphisms in genes involved with FGF21 signaling as being associated with increased alcohol consumption in humans. However, the neural circuit(s) through which FGF21 signals to suppress alcohol consumption are unknown, as are its effects on alcohol consumption in higher organisms. Here, we demonstrate that administration of an FGF21 analog to alcohol-preferring non-human primates reduces alcohol intake by 50%. Further, we reveal that FGF21 suppresses alcohol consumption through a projection-specific subpopulation of KLB-expressing neurons in the basolateral amygdala. Our results illustrate how FGF21 suppresses alcohol consumption through a specific population of neurons in the brain and demonstrate its therapeutic potential in non-human primate models of excessive alcohol consumption.
Alcohol use during pregnancy is a leading, preventable cause of birth defects and developmental disabilities in the United States, with fetal alcohol syndrome (FAS) being one of the most severe outcomes. Current survey statistics find that approximately one in eight pregnant women (500,000 per year) report alcohol use, with approximately 80,000 reporting binge drinking. While annual rates have fluctuated, trends analysis finds that there has been no significant change in rates of prenatal alcohol exposure over the past 10-year period. Development of effective programs to prevent FAS and to monitor the success of prevention efforts requires epidemiological data systems to inform these activities. This article describes alcohol use patterns among childbearing-age women and data sources that can be used in monitoring this behavior.
The diagnosis of an infant, especially a newborn, with fetal alcohol spectrum disorder is difficult due to the fact that not all of the features are apparent at that time. Many cases are also missed due to inadequate knowledge of the mother's drinking pattern and because of the examining physician's lack of experience with the disorder. While conducting a study of the use of maternal blood markers to determine alcohol use in pregnancy, we have evaluated systematically the effects of alcohol on the newborn infant. We have developed a facial scoring system consisting of six of the features commonly seen in children with fetal alcohol syndrome (FAS) and present preliminary data about its use. By using a cutoff of four or more of these six features, there is a significant correlation with the presence of these features and the mother's self-reported alcohol use. In addition, there has been no significant difference in the frequency of positive scores between newborns of Caucasian or Black ancestry. We propose that this system may be useful in the assessment of newborn infants at high risk because of alcohol exposure during pregnancy.
