Abstract
This study aims to evaluate the effects of an angiotensin receptor blocker (ARB)/calcium channel blocker combination on blood pressure control, lipid profile, insulin sensitivity, and inflammation markers. We randomized 276 hypertensive patients to olmesartan 20 mg, amlodipine 10 mg, or a single pill containing an olmesartan/amlodipine combination 20/5 mg for 12 months. We evaluated the following: body weight, systolic and diastolic blood pressure, fasting plasma glucose, fasting plasma insulin (FPI), M value, lipid profile, adiponectin (ADN), high sensitivity C-reactive protein (Hs-CRP), monocyte chemoattractant protein-1 (MCP-1), and macrophage migration inhibitory factor-1β (MIP-1β). Olmesartan/amlodipine combination better reduced blood pressure, FPI, homeostasis model assessment index, and increased M value and ADN compared to olmesartan and amlodipine monotherapies. Olmesartan/amlodipine significantly decreased Hs-CRP, MCP-1, and MIP-1β. In this multicenter, randomized, double-blind, clinical study, ARB/calcium antagonist combination resulted to be more effective than single monotherapies in reducing blood pressure, in improving insulin sensitivity, and in reducing inflammation parameters in patients with stage I essential hypertension.

Abstract
The purpose of this study was to evaluate a fixed olmesartan/amlodipine combination on blood pressure control, lipid profile, insulin sensitivity, and some inflammatory markers compared with single-drug monotherapy. A total of 276 hypertensive patients were randomly assigned to olmesartan 20 mg, amlodipine 10 mg, or a single pill containing olmesartan/amlodipine combination 20/5 mg for 12 months. We evaluated the following at baseline and after 6 and 12 months: body weight, body mass index, systolic (SBP) and diastolic blood pressures (DBP), fasting plasma glucose (FPG), fasting plasma insulin (FPI), lipid profile, tumor necrosis factor-α (TNF-α), retinol binding protein-4 (RBP-4), and interleukins 6 and 7 (IL-6 and IL-7). At baseline, and after 6 and 12 months, patients underwent an euglycemic, hyperinsulinemic clamp. The olmesartan/amlodipine combination provided a greater decrease of SBP and DPB compared with amlodipine and olmesartan monotherapies. The olmesartan/amlodipine combination decreased FPG after 12 months compared with amlodipine monotherapy. The combination decreased FPI and homeostasis model assessment index and increased M value both compared with baseline and with olmesartan and amlodipine monotherapies. Olmesartan/amlodipine decreased IL-7, but not IL-6, compared with single drug components. The olmesartan/amlodipine combination is effective and safe in reducing blood pressure and has some additive effects not shown by single drugs, such as an improvement of IL-7.

Abstract
OBJECTIVES Minodronate is a nitrogen-containing bisphosphonate that is commercially available for the treatment of osteoporosis in Japan. Preclinical studies demonstrated that minodronate is at least 10 times more potent than alendronate in inhibiting bone resorption in vivo. A high incidence of fractures, particularly of the hip, represents an important problem in Alzheimer disease (AD) patients who are prone to falls and may have osteoporosis. METHODS A total of 256 elderly patients with AD were assigned to daily treatment with 1.0 mg of minodronate or a daily treatment with risedronate combined with daily 1000 IU ergocalciferol and 1200 mg elemental calcium, and followed up for 12 months. RESULTS At baseline, patients of both groups showed low 25-hydroxyvitamin D with compensatory hyperparathyroidism. Non-vertebral fractures occurred in 5 patients in the minodronate group and 7 patients in the risedronate group (5 hip fractures; one fracture each at the distal forearm and pelvis). There was no difference in risk of hip fracture between the two groups (p=.70; odds ratio=0.8). CONCLUSIONS The study medications were well tolerated with relatively few adverse events and were equivalent in reducing the risk of a fracture in elderly patients with AD.
