1 Polymorphisms in Genes Encoding the Estrogen Metabolism Enzymes and Effects of Hormone Therapy for Oral Low Dose or Not Oral on Variables Related Endothelial Function, Inflammation and Metabolic Profile in Patients in Recent Menopause Study Pharmacogenetic

This is cross-over, randomized clinical trial, with objective to evaluate the effects of low-dose oral hormone therapy and non-oral hormone therapy on endothelial function markers (fibrinogen, von Willebrand factor, c-reactive protein), natriuretic peptide and on anthropometric, metabolic and hormonal variables in early and healthy postmenopausal women and analyzing polymorphisms in the estrogen receptor gene and FTO polymorphisms Patients will be randomized to receive oral hormone treatment or non-oral hormone treatment The investigators hypothesis is that a different genotypes in the receptor estrogen gene and FTO may have an influences on treatment response in metabolic markers and cardiovascular risk

2 Dopamine Action on Metabolism Depending on Genetic Heterogeneity - a Randomized, Placebo-controlled Double Blind Study

Obesity is a widespread disease with increasing prevalence and associated with serious secondary complications. So far, the origin of the disease, regardless of an existing positive energy balance, is not fully understood. In addition to environmental factors, the genetic background plays an important role in the pathogenesis of obesity. Of common genetic polymorphisms, variants in the fat mass and obesity associated gene (FTO) locus have the highest effect size on body weight. Animal and first clinical studies indicate that FTO variants interact with dopamine signaling in the brain, thus influencing the risk of overweight. In fact, preliminary results indicate that enhancing dopamine signaling with the dopamine agonist bromocriptine, depending on the FTO genotype, either induces weight loss or has a neutral effect on body weight. The planned clinical trial serves to develop a genotype-specific and thus individualized therapy approach for obesity. The influence of dopamine agonist therapy on weight loss as a function of the FTO (rs8050136) genotype is to be tested. Here, the greatest weight loss is expected to occur in subjects carrying the homozygous risk-allele (AA). So far, there are only a few established conservative therapy forms of obesity, so that bariatric interventions with an increasing rate are necessary to achieve weight loss and thus a reduction in overall morbidity and mortality. Among the approved drug therapies for obesity, bromocriptine is commonly used. In addition, some interventions require injections. An early, conservative individualized, genotype-specific treatment with little side-effects would enable simple treatment of obesity. Study design: 150 obese (BMI > 30) subjects (50 / study center) will be enrolled in the study. The subjects will be stratified according to their FTO genotype (rs8050136). Subjects will be randomized into placebo or bromocriptine treatment group. Treatment will last for 18 weeks and a follow-up will be performed 30 weeks after baseline.
