Comparative Efficacy and Safety of Adjuvant Letrozole Versus Anastrozole in Postmenopausal Patients With Hormone Receptor-Positive, Node-Positive Early Breast Cancer: Final Results of the Randomized Phase III Femara Versus Anastrozole Clinical Evaluation (FACE) Trial.

Purpose The Letrozole (Femara) Versus Anastrozole Clinical Evaluation (FACE) study compared the efficacy and safety of adjuvant letrozole versus anastrozole in postmenopausal patients with hormone receptor (HR) -positive and node-positive early breast cancer (eBC). Methods Postmenopausal women with HR-positive and node-positive eBC were randomly assigned to receive adjuvant therapy with either letrozole (2.5 mg) or anastrozole (1 mg) once per day for 5 years or until recurrence of disease. Patients were stratified on the basis of the number of lymph nodes and human epidermal growth factor receptor 2 status. The primary end point was 5-year disease-free survival (DFS), and the key secondary end points were overall survival and safety. Results A total of 4,136 patients were randomly assigned to receive either letrozole (n = 2,061) or anastrozole (n = 2,075). The final analysis was done at 709 DFS events (letrozole, 341 [16.5%]; anastrozole, 368 [17.7%]). The 5-year estimated DFS rate was 84.9% for letrozole versus 82.9% for anastrozole arm (hazard ratio, 0.93; 95% CI, 0.80 to 1.07; P = .3150). Exploratory analysis showed similar DFS with letrozole and anastrozole in all evaluated subgroups. The 5-year estimated overall survival rate was 89.9% for letrozole versus 89.2% for anastrozole arm (hazard ratio, 0.98; 95% CI, 0.82 to 1.17; P = .7916). Most common grade 3 to 4 adverse events (> 5% of patients) reported for letrozole versus anastrozole were arthralgia (3.9% v 3.3%, and 48.2% v 47.9% for all adverse events), hypertension (1.2% v 1.0%), hot flushes (0.8% v 0.4%), myalgia (0.8% v 0.7%), dyspnea (0.8% v 0.5%), and depression (0.8% v 0.6%). Conclusion Letrozole did not demonstrate significantly superior efficacy or safety compared with anastrozole in postmenopausal patients with HR-positive, node-positive eBC.

The burden of bacteremia and invasive diseases in children aged less than five years with fever in Italy.

BACKGROUND: Invasive diseases (ID) caused by Streptococcus pneumoniae (S. pneumoniae), Haemophilus influenzae (H. influenzae), and Neisseria meningitidis are a major public health problem worldwide. Comprehensive data on the burden of bacteremia and ID in Italy, including data based on molecular techniques, are needed. METHODS: We conducted a prospective, multi-centre, hospital-based study (GSK study identifier: 111334) to assess the burden of bacteremia and ID among children less than five years old with a fever of 39 °C or greater. Study participation involved a single medical examination, collection of blood for polymerase chain reaction (PCR) and blood culture, and collection of an oropharyngeal swab for colonization analysis by PCR. RESULTS: Between May 2008 and June 2009, 4536 patients were screened, 944 were selected and 920 were enrolled in the study. There were 225 clinical diagnoses of ID, 9.8 % (22) of which were bacteremic. A diagnosis of sepsis was made for 38 cases, 5.3 % (2) of which were bacteremic. Among the 629 non-ID diagnoses, 1.6 % (10) were bacteremic. Among the 34 bacteremic cases, the most common diagnoses were community-acquired pneumonia (15/34), pleural effusion (4/34) and meningitis (4/34). S. pneumoniae was the most frequently detected bacteria among bacteremic cases (29/34) followed by H. influenzae (3/34). Ninety percent (27/30) of bacteremic patients with oropharyngeal swab results were colonized with the studied bacterial pathogens compared to 46.1 % (402/872) of non-bacteremic cases (p < 0.001). PCV7 (7-valent pneumococcal conjugate vaccine) vaccination was reported for 55.9 % (19/34) of bacteremic cases. S. pneumoniae serotypes were non-vaccine serotypes in children who had been vaccinated. Mean duration of hospitalization was longer for bacteremic cases versus non-bacteremic cases (13.6 versus 5.8 days). CONCLUSIONS: These results confirm that S. pneumoniae is one of the pathogens frequently responsible for invasive disease.

Prevalence of type 2 diabetes among patients with hypertension under the care of 30 Italian clinics of hypertension: results of the (Iper)tensione and (dia)bete study.

BACKGROUND AND PURPOSE: Hypertension is known to be highly prevalent among patients with diabetes and associated with an increased risk of cardiovascular damage. In contrast, relatively few investigations have addressed the prevalence of diabetes among patients with hypertension. The purpose of the present study was to examine the prevalence of type 2 diabetes, the effectiveness of hypertension and diabetes control and the association with other cardiovascular risk factors and previous cardiovascular diseases in a cohort of patients with hypertension referred to 30 hospital outpatient clinics for the treatment of hypertension. METHODS AND PATIENTS: Patients were considered as having diabetes if they were already on an antidiabetic treatment either with diet or medications. All other patients had fasting plasma glucose measured on two separate occasions and were classified as having diabetes if both values were at least 140 mg/dl (7.8 mmol/l) and as not having diabetes if both values were less than 110 mg/dl (6.1 mmol/l). In patients with a single determination of at least 110 mg/dl, the final diagnosis of diabetes was established according to the result of an oral glucose tolerance test. A secondary definition of diabetes was also used, that is two fasting plasma glucose values of at least 126 mg/dl (7.0 mmol/l). In all patients, serum total, high-density lipoprotein cholesterol and low-density lipoprotein cholesterol, fasting serum triglycerides, serum creatinine and urinary albumin were also evaluated. RESULTS AND CONCLUSION: Among the 1397 recruited patients, 242 (17.3%) were diagnosed as having diabetes according to the primary definition and 244 (17.5%) according to the secondary definition. In 195 out of the 242 (14%), the diagnosis was already known whereas, in the remaining 47 (3.3%), it was made de novo. In 61.4% of those already having diabetes, plasma glucose was at least 140 mg/dl (7.8 mmol/l), whereas only in 8.4% of them was it less than 110 mg/dl (6.1 mmol/l). Patients with diabetes were older, heavier and with a greater familiar predisposition. Patients with diabetes had higher values of systolic blood pressure than individuals without diabetes (150 +/- 17 vs. 144 +/- 16 mmHg, respectively; P < 0.001), lower high-density lipoprotein cholesterol and higher triglycerides and microalbuminuria. Overall, among patients with hypertension and diabetes, only 3% had blood pressure and HbA1c within the recommended limits. The prevalence of previous cardiovascular disorders was two to three times higher than among individuals without diabetes.

Left ventricular diastolic dysfunction in elderly hypertensives: results of the APROS-diadys study.

BACKGROUND: A number of patients with chronic heart failure (CHF) have diastolic but not systolic dysfunction. This occurs particularly in the elderly and in hypertension, but the prevalence of diastolic dysfunction in elderly hypertensives without CHF has never been investigated systematically. METHODS AND RESULTS: The Assessment of PRevalence Observational Study of Diastolic Dysfunction (APROS-diadys) project was a cross-sectional observational study on elderly (age >/= 65 years) hypertensives without systolic dysfunction [left ventricular ejection fraction (LVEF) >/= 45%] consecutively attending hospital outpatient clinics in Italy, in order to establish the prevalence of echocardiographic signs of diastolic dysfunction according to various criteria, and to correlate them with a number of demographic and clinical characteristics. Primary criteria for diastolic dysfunction was an E/A ratio (ratio between transmitral peak velocities of E and A waves) < 0.7 or > 1.5 on echocardiographic Doppler examination. Secondary criteria were: E/A < 0.5 and deceleration time (DT) > 280 ms, or isovolumic relaxation time (IVRT) > 105 ms or pulmonary vein (PV) peak systolic/peak diastolic flow (S/D) ratio > 2.5 or PV atrial retrograde flow (PV A) > 35 cm/s. Throughout Italy, 27 447 patients were screened in 107 clinics, with 24 141 excluded according to protocol. Among the remaining 3336 patients, 754 (22.6%) had signs of CHF. After exclusion of 37 protocol violators, 2545 patients (49.0% men, mean age 70.3 years, 95.4% under antihypertensive treatment) were studied ultrasonographically. Diastolic dysfunction (primary criteria) was found in 649 (25.8%) patients. Multiple logistic regression analysis found age, gender, left ventricular mass, systolic and pulse pressures and midwall shortening fraction as significant covariates. Using secondary criteria, the prevalence of diastolic dysfunction was higher (45.6%), mostly because of IVRT > 105 ms or PVA flow > 35 cm/s. CONCLUSION: CHF and diastolic dysfunction are highly prevalent in elderly hypertensives attending hospital clinics.
