Abstract
OBJECTIVE The effects of anticonvulsants on lipids are the subject of considerable concern and investigation, but there are almost no data on this issue from randomized trials. We evaluated serum lipid profiles in adults with newly diagnosed epilepsy, following randomization to lacosamide (LCM) or carbamazepine (CBZ) monotherapy. METHODS We analyzed data from a Phase 3, international, randomized, double-blind trial of LCM vs CBZ for the initial treatment of focal epilepsy. Serum lipid profiles in patients not taking lipid-lowering agents and providing blood samples under fasting conditions before treatment, and following 3 or 12 months of treatment with LCM or CBZ at various doses were analyzed. RESULTS At 12 months, 271 patients satisfied the inclusion criteria for the analysis. No change was observed in LCM-treated patients for total cholesterol, cholesterol fractions, or triglycerides. CBZ-treated patients showed an increase of 21.1 mg/dL in total cholesterol, 12.6 mg/dL in low-density lipoprotein (LDL) cholesterol, 12.5 mg/dL in non-high density lipoprotein (non-HDL) cholesterol, and 8.5 mg/dL in HDL cholesterol; triglycerides remained unchanged. The proportion of patients with elevated total cholesterol levels (above the upper limit of the reference range) did not change in the LCM treatment group (37.0% at Baseline; 34.8% at 12 months), but increased from 30.8% (at Baseline) to 49.6% (at 12 months) in the CBZ treatment group. SIGNIFICANCE This study provides Class II evidence that CBZ elevates serum lipids, whereas LCM has no effect on lipids. It supports LCM as an appropriate choice for new-onset focal epilepsy.

Abstract
Recent data have revealed that oxidative products and inflammatory mediators are increased in the insulin-resistant states of obesity and type 2 diabetes mellitus (T2DM). Obese patients with impaired glucose tolerance (IGT) are at high risk for developing T2DM and have high incidence of dyslipidemia. α-Lipoic acid (ALA) is a potent antioxidant with insulin sensitizing activity. However, it is not clear whether ALA is effective on lipid parameters in humans. This study has investigated 22 obese subjects with IGT (obese-IGT), 13 of whom underwent 2-week ALA treatment, 600 mg intravenously once daily. Before and after the treatment, euglycemic-hyperinsulinemic clamps were used to measure insulin sensitivity. Meanwhile, plasma lipids, oxidative products, and chronic inflammatory markers were measured. After treatment of ALA in obese-IGT patients, insulin sensitivity was improved, insulin sensitivity index (ISI) impressively enhanced by 41%. Plasma levels of free fatty acids (FFAs), triglyceride (TG), total cholesterol (T-Chol), low density lipoprotein-cholesterol (LDL-Chol), small dense LDL-Chol (sd-LDL), oxidized LDL-Chol (ox-LDL-Chol), very low density lipoprotein-cholesterol (VLDL-Chol) were all significantly decreased (P < 0.01). At the same time, both plasma oxidative products (malondialdehyde (MDA), 8-iso-prostaglandin) and inflammatory markers (tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6)) were remarkably decreased (P < 0.01), while adiponectin was increased (P < 0.01). There are significant negative correlations between ISI and plasma FFAs, sd-LDL-Chol, ox-LDL-Chol, MDA, 8-iso-prostaglandin, TNF-α, and IL-6, and positive correlations with HDL-Chol and adiponectin in obese-IGT patients. The results indicate that short-term treatment with ALA can improve insulin sensitivity and plasma lipid profile possibly through amelioration of oxidative stress and chronic inflammatory reaction in obese patients with IGT.

Abstract
PURPOSE To compare the short-term effect of treatment with atorvastatin and rosuvastatin on levels of serum lipids, inflammatory markers and adiponectin in patients with hypercholesterolemia. METHODS Sixty-nine patients with hypercholesterolemia were randomly assigned to receive 10 mg/day of atorvastatin or rosuvastatin for 12 weeks. Inflammatory biomarkers, including highsensitivity C-reactive protein (hs-CRP), tumor necrosis factor (TNF)-alpha, matrix metalloproteinase-9 (MMP-9), and endothelin (ET-1), plasminogen activator inhibitor type 1 (PAI-1) and plasma tissue plasminogen activator (tPA), adiponectin, and lipid profiles were measured before and after statin therapy. RESULTS Atorvastatin and rosuvastatin both lowered levels of hs-CRP, MMP-9, PAI-1, total cholesterol (TC), and low-density lipoprotein cholesterol (LDL-C) from baseline values, with rosuvastatin lowering TC and LDL-C to a greater extent than atorvastatin (P < 0.05). Adiponectin level increase was 15% higher than that at baseline with atorvastatin (P > 0.05) but 67% higher with rosuvastatin (P < 0.05). CONCLUSIONS Therapy with both statins not only significantly improved lipid profiles but also decreased levels of vascular biomarkers hs-CRP, MMP-9, and PAI-1; however, only rosuvastatin increased serum adiponectin levels significantly in patients with hypercholesterolemia, which could imply a beneficial effect in coronary artery disease.

Abstract
BACKGROUND Raloxifene has been approved for prevention and treatment of postmenopausal osteoporosis in Caucasian women. It also has some positive effects on serum lipids in Caucasians. The objective of this study was to determine the effect of raloxifene hydrochloride on lumbar spine and total hip bone mineral density (BMD), bone metabolism, and serum lipids in Chinese postmenopausal women with osteoporosis. METHODS This was a multi-center, randomized, double-blind, placebo-controlled clinical trial in which 204 postmenopausal Chinese women with osteoporosis were assigned to receive raloxifene (60 mg) or placebo treatment daily for 12 months. BMD, serum bone metabolism markers, and serum lipids were measured before and after drug administration. BMD was measured by Dual-Energy X-Ray Absorptiometry (DEXA) and bone metabolism markers were analyzed by one-step enzyme-linked immunosorbent assay. Serum lipids were measured by enzymatic analysis. RESULTS At the end of the 12-month study, lumbar spine BMD increased in both groups with a mean increase of (3.3 +/- 4.8)% in the raloxifene group and (1.0 +/- 4.9)% in the placebo group (P < 0.001). There was a mean increase in total hip BMD of (1.4 +/- 4.8)% in the raloxifene group and a mean decrease of (0.9 +/- 5.0)% in the placebo group (P < 0.001). No subject in the raloxifene group had a new vertebral fracture and 5 placebo subjects had new fractures (P > 0.05). In the raloxifene group, the median decreases in the biochemical markers of bone metabolism serum osteocalcin and C-telopeptide were 41.7% and 61.5%, respectively. These changes were statistically significant compared with those in the placebo group (10.6% and 35.6%, P < 0.001, respectively). Both total cholesterol and low-density lipoprotein cholesterol decreased significantly in the raloxifene group compared with those in the placebo group (P < 0.001, respectively) and there was no significant effect of raloxifene on high-density lipoprotein cholesterol and triglycerides compared with placebo. CONCLUSIONS Raloxifene 60 mg/d for 12 months significantly increases lumbar spine and total hip BMD, significantly decreases bone turnover, and has favourable effects on serum lipids in Chinese postmenopausal women with osteoporosis.

Abstract
OBJECTIVE To determine the effects of raloxifene hydrochloride (RLX) on bone mineral density (BMD), bone metabolism markers and serum lipids in healthy postmenopausal women in Beijing. METHODS A multicenter, randomized, double-blind, placebo-controlled study was conducted in a total of 204 healthy postmenopausal women (age 59.5 +/- 5.0 years and weight 62.8 +/- 8.7 kg) treated with either RLX 60 mg (n = 102) or placebo (n = 102) daily for 12 months. BMD, serum lipids, and bone markers were measured before and after drug administration. RESULTS Compared with placebo, RLX produced a significant increase in both total lumbar spine and total hip BMD. For the lumbar spine, percentage increase in total BMD was 2.3% with RLX compared with a decrease of 0.1% with placebo (P < 0.001). Corresponding values for total hip BMD were a 2.5% increase for RLX and a 1.1% increase for placebo (P = 0.011). For biochemical markers of bone metabolism, serum osteocalcin and C-telopeptide, percentage decreases were 27.65% and 24.02% in RLX-treated subjects. Corresponding values in placebo were a 10.64% decrease and a 15.75% increase (RLX compared with placebo, both P < 0.001). For total cholesterol and low-density lipoprotein cholesterol levels, percentage decreases were 6.44% and 34.58% in the RLX-treated group. Corresponding values in placebo-treated patients were a 1.44% increase and a 19.07% decrease (RLX compared with placebo, both P < 0.001). No differences were found for high-density lipoprotein cholesterol or triglyceride levels between the two groups. Only 5 subjects discontinued early owing to an adverse event (3 in the RLX group and 2 in the placebo group). CONCLUSIONS This study confirms that RLX exerts positive effects on the skeleton, increasing BMD and decreasing biochemical markers of bone metabolism, and has a positive effect on the overall serum lipid profile in postmenopausal women in China.
