CR1 allelic distribution in healthy italians and SLE patients
Complement receptor type 1 (CR1; CD35), the receptor for C3b/C4b, has a molecular weight polymorphism involving four co-dominantly expressed alleles CR1*1, CR1*2, CR1*3 and CR1*4. The most common allotype in the Caucasian population is CR1*1. Previous studies on the frequency of the CR1 allele in Systemic Lupus Erythematosus (SLE) patients reported conflicting results. Recently an increased frequency of the CR1*2 allele was reported in Caucasian SLE patients. The aim of our study is to assess the frequency of CR1 structural alleles in a sample of the Italian population and in a cohort of Italian SLE patients equally distributed nationwide. We found that the most common phenotype was CR1*1.1…
Effects of extra-virgin olive oil enriched with E-vitamin and Q10-coenzyme on the heart rate variability and plasma antioxidant status in athletes
OBJECTIVES: To examine whether the assumption of extra virgin olive oil enriched with E-vitamin and Q10-coenzyme may improve the plasma anti-oxidant/pro-oxidant balance and be associated with favorable changes in heart rate variability (HRV). METHODS: Four male athletes, mean age 22 (range 21-24), were recruited. They assumed 20 ml per day of the integrator (20 mg Q10 and 15 mg Vit E) for one month. The plasma antioxidant capacity (AC) was evaluated by the crocin bleaching assay. The frequency-domain analysis of HRV was carried out using Cardioline Cube recorder and specific software to obtain, from an autoregressive power spectrum approach, the power in normalized units (nu) of the low-(LF…
Comparison of Right Ventricular Longitudinal Strain Imaging, Tricuspid Annular Plane Systolic Excursion, and Cardiac Biomarkers for Early Diagnosis of Cardiac Involvement and Risk Stratification in AL Amyloidosis: a Five Year Cohort Study
Objectives: The aim was to determine the role of assessing right ventricular (RV) function, using standard echocardiography and Doppler myocardial imaging (DMI), in the early diagnosis of cardiac amyloidosis (CA) and in prediction of mortality. Methods: A total of 249 patients with AL amyloidosis were categorized on the basis of left ventricular thickness and E' velocity, and compared to 38 age- and sex-matched controls. Standard echocardiographic parameters of RV function were assessed, and longitudinal systolic myocardial velocity, strain rate (sSR), and strain (sS) were determined for the basal and middle RV free wall segments. Patients were followed for the endpoint of mortality. Result…
