Human leukocyte antigen B (HLA-B) is a gene that encodes a cell surface protein involved in presenting antigens to the immune system. The variant allele HLA-B*15:02 is associated with an increased risk of Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) in response to carbamazepine treatment. We summarize evidence from the published literature supporting this association and provide recommendations for the use of carbamazepine based on HLA-B genotype (also available on PharmGKB: http://www.pharmgkb.org). The purpose of this article is to provide information to allow the interpretation of clinical HLA-B*15:02 genotype tests so that the results can be used to guide the use of carbamazepine. The guideline provides recommendations for the use of carbamazepine when HLA-B*15:02 genotype results are available. Detailed guidelines regarding the selection of alternative therapies, the use of phenotypic tests, when to conduct genotype testing, and cost-effectiveness analyses are beyond the scope of this document. Clinical Pharmacogenetics Implementation Consortium (CPIC) guidelines are published and updated periodically on the PharmGKB website at (http://www.pharmgkb.org).
11Beta-hydroxysteroid dehydrogenase-1 (11beta-HSD-1) plays a key role in the regulation of intracellular glucocorticoid concentrations. Increased message and/or activity of adipose 11beta-HSD-1 are characteristics of human and animal models of obesity. Hexose-6-phosphate dehydrogenase (H6PDH) is colocalized with 11beta-HSD-1 and may be a critical factor in determining the oxo-reductase activity of 11beta-HSD-1. This study examined the effects of sucrose solution access on body weight, body composition, and message of 11beta-HSD-1 and H6PDH in mesenteric adipose and liver. Rats were assigned to 3 groups: 1) control (ad libitum intake of nonpurified diet and water only); 2) ad libitum intake of 16% sucrose solution (S16); or 3) ad libitum intake of 32% sucrose solution (S32) in addition to ad libitum intake of diet and water. The S32 group consumed more energy daily than the S16 and control groups, yet body weight did not differ among groups. Percentages of body fat did not differ between the S16 and S32 groups but were higher than in controls. Hepatic 11beta-HSD-1 message was suppressed by 46% in the S16 group and by 47% in the S32 group, whereas the H6PDH message nearly doubled in the S16 group compared to the control group. In mesenteric fat, 11beta-HSD-1 message increased 23-fold in the S16 group and 32-fold in the S32 group and the H6PDH message increased 3.5-fold in the S16 group compared to the control group. These data demonstrate that sucrose can promote increased 11beta-HSD-1 and H6PDH message in mesenteric fat while concomitantly decreasing 11beta-HSD-1 message and increasing H6PDH message in liver. These observations support the hypothesis that sucrose access causes obesity via its ability to increase adipose 11beta-HSD-1.
This study found that veterans prescribed buprenorphine/naloxone in a group setting as part of a drug and alcohol treatment program were retained in treatment longer than veterans prescribed this medication individually. Because of inherent limitations in the study design, no causality can be determined; however, given the results found here, group medication management of buprenorphine/naloxone should be explored further.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
