BACKGROUND: Obesity has high prevalence among HIV-infected patients. Increased adipose tissue mass affects the pharmacokinetics of numerous drugs, but few data are available for antiretroviral drugs. OBJECTIVES: In this study we aimed to explore the pharmacokinetics of antiretroviral drugs and the immuno-virological response in obese patients with HIV infection. PATIENTS AND METHODS: We examined data from 2009 to 2012 in our hospital's database for HIV-1-infected patients who received an antiretroviral drug (abacavir, emtricitabine, lamivudine, tenofovir, efavirenz, etravirine, nevirapine, atazanavir/ritonavir, darunavir/ritonavir, lopinavir/ritonavir or raltegravir)...

OBJECTIVE: Evidence supports the need of dose-adjustment of several drugs according to body mass index (BMI) to prevent toxicity in the underweight, and ensure efficacy in obese women. However, for MgSO4 neuroprotection, the effect of BMI on maternal toxicity and fetal neuroprotection is understudied. We analyze the effect of BMI on maternal/infant outcomes after MgSO4. METHODS: Secondary analysis of a clinical trial that studied MgSO4 neuroprotection. Maternal side effects, magnesium cord levels, and offspring cerebral palsy/death were analyzed along BMI strata using ANOVA and chi-square test...

Polycystic ovary syndrome (PCOS) is the most common endocrine disorder in females and is often associated with a number of cardiometabolic disorders such as central obesity, dyslipidaemia, hypertension, insulin resistance, hyperinsulinaemia, glucose intolerance and type 2 diabetes mellitus (T2DM). Glucagon-like peptide-1 (GLP-1), a gut hormone secreted after a meal, enhances glucose-stimulated insulin secretion and additionally suppresses appetite and gastric motility. Most studies found impaired GLP-1 kinetics in obese individuals, whereas small studies in PCOS reported reduced, normal or even elevated GLP-1 levels...

AIMS: Evidence indicates that obese individuals exhibit alterations in brain-reward function that are anatomically and functionally similar to what has been observed in drug addicts, which could theoretically make obese individuals vulnerable to drug abuse and drug abusers vulnerable to overeating. However, few studies have investigated the cross-generality of these phenotypes. We recently reported that the reinforcing effectiveness (i.e., value) of a fat was greater in obese Zucker rats than in their lean counterparts, but found no differences in the reinforcing effectiveness of cocaine between groups, suggesting psychostimulant reinforcement is similar in lean and obese Zucker rats...

Melanin-concentrating hormone (MCH), a cyclic neuropeptide expressed predominantly in the lateral hypothalamus, plays an important role in the control of feeding behavior and energy homeostasis. Mice lacking MCH or MCH1 receptor are resistant to diet-induced obesity (DIO) and MCH1 receptor antagonists show potent anti-obesity effects in preclinical studies, indicating that MCH1 receptor is a promising target for anti-obesity drugs. Moreover, recent studies have suggested the potential of MCH1 receptor antagonists for treatment of non-alcoholic fatty liver disease (NAFLD)...

For treatment of patients with diseases of lower limb arteries and prevention of cardiovascular complications in high-risk patients (those with diabetes mellitus, arterial hypertension, dyslipidemia, obesity) permanent antiplatelet therapy is indicated. A problem is variable individual sensitivity to therapeutic agents. For antiplatelet therapy in patients with atherosclerosis of lower limb arteries there has been obtained an evidence-supported base concerning efficacy of long-term administration of clopidogrel preparations, unlike patients with acute coronary syndrome, for whom there has been accumulated an evidence-confirmed base of administering clopidogrel preparations, as well as ticagrelor and prasugrel in various clinical situations...

The optimal antibiotic prophylaxis dosing regimen of cefazolin for cesarean delivery (CD) in overweight and obese women is unknown. This study was done to compare the duration that cefazolin concentrations remain above the minimum inhibitory concentration (MIC) in adipose tissue (AT). Serum and AT concentrations from 3 previous studies in CD patients were comodeled using the nonparametric adaptive grid algorithm in Pmetrics. AT concentrations for 5000 overweight and obese patients receiving 1-, 2-, and 3-g cefazolin regimens were simulated to calculate the probability that free drug concentrations remained above an MIC of 2 μg/mL at 1, 1...

The present generation of women of childbearing age more frequently suffer from overweight, obesity, initial as well as fully established metabolic syndrome, which together with postponing motherhood until the third decade in life plays an important role in the increasing incidence of gestational diabetes (GDM) that currently affects about 1/5 of pregnant women. However the causal link between diabetes during pregnancy and metabolic diseases in the whole population is mutual. By way of epigenetic changes, maternal diabetes unfavourably programmes metabolism of the offspring, who tend to transfer the disorder to the next generations...

Obesity and inflammatory bowel disease (IBD) are systemic inflammatory disorders that predispose to arterial and venous thrombosis through similar prothrombotic mechanisms. Obesity and IBD are chronic risk factors that lead to a persistently elevated risk of thrombosis, although the thrombotic risk with IBD appears to wax and wane with disease severity. Because of the lack of high-quality evidence to guide management decisions, approaches to the prevention and treatment of thrombosis in patients with obesity or IBD are based on extrapolation from general guidelines for antithrombotic therapy...

BACKGROUND: Laparoscopic Roux-en-Y gastric bypass (LRYGB) surgery is a safe and effective procedure for patients with severe obesity. One potential complication of LRYGB is the development of marginal ulcers (MUs). Nonsteroidal anti-inflammatory drugs (NSAIDs) are known to significantly increase the likelihood of developing marginal ulcers after surgery. However, the risk associated with low-dose aspirin consumption is not well defined. We examined the impact of daily low-dose aspirin (81 mg) on the development of marginal ulcers following LRYGB...

Purpose Obesity (body mass index [BMI] ≥ 30 kg/m(2)) is common among patients with cancer. We reviewed management issues in the obese patient with cancer, focusing on how obesity influences treatment selection (including chemotherapy dosing), affects chemotherapy toxicity and surgical complications, and might be a treatment effect modifier. Methods The majority of evidence is drawn from observational studies and secondary analyses of trial data, typically analyzed in N × 3 BMI categories (normal weight, overweight, and obese) matrix structures...

PURPOSE: Patients suffering from obesity-related diseases use multiple prescription drugs to control their condition, and it is therefore essential to determine the safety and efficacy of any combination. Gliclazide is one of the most commonly used drug of choice for treatment of type 2 diabetes, and curcumin is a widely used herbal supplement to counter obesity condition. The objective of this study was to investigate the effect of oral administration of curcumin on pharmacodynamics and pharmacokinetics of gliclazide in rats and rabbits to further evaluate the safety and effectiveness of this combination...

BACKGROUND: Genetic polymorphisms in CYP2C9 account for 10-20% of the variability in warfarin dose requirement. As such CYP2C9 genetic polymorphisms are commonly included in algorithms aimed to optimize warfarin therapy as a way to account for variability in warfarin responsiveness that is due to altered pharmacokinetics. However, most of the currently available pharmacokinetic data were derived from studies among patients on chronic warfarin therapy and therefore suffer from the confounding effects of disease states and drug interactions...

BACKGROUND: Khat (Catha edulis) is a plant that is deeply rooted in the cultural life of East African and Southwestern Arabian populations. Prevalent traditional beliefs about khat are that the plant has an effect on appetite and body weight. SUMMARY: This review assesses the accumulated evidences on the mutual influence of monoamines, hormones and neuropeptides that are linked to obesity. A few anti-obesity drugs that exert their mechanisms of action through monoamines are briefly discussed to support the notion of monoamines being a critical target of drug discovery for new anti-obesity drugs...
