Helicobacter pylori (HP) infection is a common and persistent disorder acting as a major cofactor for the development of upper gastrointestinal diseases and several extraintestinal disorders including osteoporosis. However, no prospective study assessed the effects of HP on bone health and fracture risk. We performed a HP screening in a population-based cohort of 1149 adults followed prospectively for up to 11 years.

The pathogen burden is a concept consisting in the observation that, in patients with heart disease, damaging effects of the coronary arteries increase concomitantly with the number of agents responsible for chronic infections to which patients mounted a serological response. Previous observations that Helicobacter pylori infection may reduce the semen quality prompted us to perform the present study.

Methods: In 109 selected patients, HP infection and seminal levels of IL-6 and TNF-α were determined using enzyme-linked immunosorbent assays. Western blotting was used to detect antibodies to CagA.
Introduction: Intravenous loop diuretics are a cornerstone of therapy in acutely decompensated heart failure (ADHF). We sought to determine if there are any differences in clinical outcomes between intravenous bolus and continuous infusion of loop diuretics.
Methods: Subjects with ADHF within 12 hours of hospital admission were randomly assigned to continuous infusion or twice daily bolus therapy with furosemide.
This study aimed to investigate the associations of body composition and fat distribution with bone mineral density (BMD) in elderly Italian subjects. In 866 women (age 64.2±6.

Sclerostin is a secreted Wnt antagonist produced by osteocytes that regulates osteoblast activity and thus bone turnover. Its levels increase with age and are regulated by PTH.

We explored the possibility that this infection can influence systemic and seminal levels of ghrelin and obestatin, hormones mainly produced by the stomach. Ghrelin and obestatin exert many activities, including the regulation of reproductive biology, and are present in many organs and fluids, including human semen.

In a previous study we demonstrated that either zoledronic acid (4 mg) or neridronate (200 mg) given as a single intravenous infusion showed a similar short-term efficacy in achieving biochemical remission in up to 90% of patient nonresponders to pamidronate. In this study we compared the long-term (36 months) effects of a same neridronate dose (200 mg) given as an intravenous (100-mg infusion for 2 consecutive days) or intramuscular (25-mg injection weekly for 2 months) regimen in 56 patients with active PDB.

The aim of the study was to investigate, in patients with cardio-renal anemia syndrome, the effects of EPO on hemochrome and renal function parameters and BNP levels. We also analyzed the effect of EPO therapy on hospitalization rate and NYHA class after 12 months in comparison with a population undergoing to standard therapy.

Anemia in heart failure is related to advanced New York Heart Association classes, severe systolic dysfunction, and reduced exercise tolerance. Although anemia is frequently found in congestive heart failure (CHF), little is known about the effect of its' correction with erythropoietin (EPO) on cardiac structure and function. The present study examines, in patients with advanced CHF and anemia, the effects of beta-EPO on left ventricular volumes, left ventricular ejection fraction (LVEF), left and right longitudinal function mitral anular plane systolic excursion (MAPSE), tricuspid anular plane excursion (TAPSE), and pulmonary artery pressures in 58 patients during 1-year follow-up in a double-blind controlled study of correction of anemia with subcutaneous beta-EPO.

Infection by H. pylori and by strains expressing CagA was determined in 80 male infertile patients by Western blotting and ELISA.

The pathogenesis of AAA involves several factors, first of all destruction of collagen and elastin in the aortic wall. Classical risk factors may influence the evolution and development of AAA, though no consistent association has been found.

The mechanism of action of these drugs has not been completely clarified, but it has been observed that N-BPs may inhibit squalene synthase or farnesyl pyrophosphate synthase. Zoledronic acid (ZA) represents a novel N-BP which also has antitumor activity.

OPG has been found in several tissues, including the cardiovascular system, BNP is selectively produced by myocardial cells.
Methods: 178 consecutive patients were classified in three groups: stable angina (SA), unstable angina/non-ST elevation myocardial infarction (NSTE-ACS) and control group, measuring OPG and BNP at hospital admission.
The recommended dietary calcium intake may be difficult to reach using dairy products only. This study aimed to evaluate the absorbability of calcium of a new orange beverage in comparison with that of milk. Ten healthy adults, 5 males and 5 females, were randomly divided to receive, under fasting conditions, an orange beverage enriched either with calcium or milk.

Objectives: The present study examines in patients with advanced CHF, chronic renal insufficiency, and anemia the effects of beta-EPO on left ventricular (LV) systolic diameter and volume (LVSD and LVSV), LV diastolic diameter and volume (LVDD and LVDV), LV mass, LV ejection fraction (LVEF), pulmonary artery pressure (PAP), and B-type natriuretic peptide (BNP) levels.
Methods: Fifty-one consecutive subjects affected with advanced CHF and anemia were studied.
Several emerging cardiac markers constitute strong predictors among patients with coronary artery disease. In particular, brain natriuretic peptide (BNP), troponin T (TnT), and C-reactive protein (CRP) are related to increased risk of recurrent ischemic events and death. However, little is known about the utility of these biomarkers in combination.

Background: Recently, it was shown that B-type natriuretic peptide levels are increased in patients with acute coronary syndromes.
Aims: To assess the relation between B-type natriuretic peptide and ischemia in patients with stable and unstable angina pectoris with normal left ventricular function in relation to the extent of ischemia and response to revascularization.
Methods: Fifty-nine consecutive patients were enrolled in the study, patients were divided into two groups: stable angina patients (group I, n=18), and unstable coronary patients (group II, n=41).
Elevated plasma brain natriuretic peptide (BNP) levels have been described in patients with acute myocardial infarction and left ventricular dysfunction. The aim of the present study was to evaluate circulating BNP levels in patients with coronary artery disease without ST-segment elevation acute myocardial infarction and preserved systolic function and to evaluate the BNP levels in relation to the number of involved coronary vessels. We studied 88 patients with coronary artery disease: group 1 had stable angina, group 2 had unstable angina (UA), group 3 had non-Q-wave myocardial infarction (NSTEMI), and group 0 consisted of 15 healthy subjects.
View Article and Find Full Text PDFBackground: Several studies have documented brain natriuretic peptide (BNP) behavior during cardiac ischemia and after myocardial necrosis. Peptide levels have been shown to be increased during acute phase of cardiac ischemia and during late ventricular remodelling; however, there are fewer data about hormone levels during percutaneous transluminal coronary angioplasty (PTCA) and aorto-coronaric by pass (CABG).
Methods: Aim of this study was to investigate plasma BNP during acute or sub-acute myocardial ischemia in patients undergoing to PTCA or CABG, taking blood samples before and after both procedures.
