Switching from statin monotherapy to ezetimibe/simvastatin or rosuvastatin modifies the relationships between apolipoprotein B, LDL cholesterol, and …
2011
OBJECTIVE: To evaluate relationships between apolipoprotein B (Apo B), LDL cholesterol (LDL-C), and non-HDL-C in high-risk patients treated with lipid-lowering therapy. DESIGN AND METHODS: This post-hoc analysis calculated LDL-C and non-HDL-C levels corresponding to an Apo B of 0.9 g/L following treatment with 1) statin monotherapy (baseline) and 2) ezetimibe/simvastatin 10/20mg or rosuvastatin 10mg (study end). The percentages of patients reaching LDL-C, non-HDL-C, and Apo B targets were calculated at study end. RESULTS: After switching to ezetimibe/simvastatin or rosuvastatin, the LDL-C and non-HDL-C corresponding to Apo B=0.9 g/L were closer to the more aggressive LDL-C and non-HDL-C goa…
White blood cell counts as risk markers of developing metabolic syndrome and its components in the Predimed study.
2013
Journal Article; Multicenter Study; Randomized Controlled Trial; Research Support, Non-U.S. Gov't; TRIAL REGISTRATION Controlled-Trials.comISRCTN35739639. BACKGROUND The Metabolic Syndrome (MetS) is a cluster of metabolic abnormalities that includes hyperglucemia, hypertension, dyslipidemia and central obesity, conferring an increased risk of cardiovascular disease. The white blood cell (WBC) count has been proposed as a marker for predicting cardiovascular risk. However, few prospective studies have evaluated the relationship between WBC subtypes and risk of MetS. METHODS Participants were recruited from seven PREDIMED study centers. Both a baseline cross-sectional (n = 4,377) and a prospe…
Monitoring effectiveness and safety of Tafamidis in transthyretin amyloidosis in Italy: a longitudinal multicenter study in a non-endemic area
2016
Tafamidis is a transthyretin (TTR) stabilizer able to prevent TTR tetramer dissociation. There have been a few encouraging studies on Tafamidis efficacy in early-onset inherited transthyretin amyloidosis (ATTR) due to Val30Met mutation. However, less is known about its efficacy in later disease stages and in non-Val30Met mutations. We performed a multi-center observational study on symptomatic ATTR patients prescribed to receive Tafamidis. We followed up patients according to a standardized protocol including general medical, cardiological and neurological assessments at baseline and every 6 months up to 3 years. Sixty-one (42 males) patients were recruited. Only 28 % of enrolled subjects h…
Association between the HFE mutations and longevity: a study in Sardinian population
2003
Hereditary hemochromatosis is an HLA-linked inherited disease characterised by inappropriately high absorption of iron by the gastrointestinal mucosa. The cysteine-to-tyrosine substitution at codon 282 of the HFE encoding gene sequence is responsible for the disease, although other variants, as H63D and S65C, may modify the affinity of the protein for transferrin receptors. We have recently reported that C282Y mutation is significantly increased in very old (>90 years) Sicilian women, suggesting a role in attainment of longevity. In addition, an increase of H63D polymorphism was also observed in these women but the difference was not significant. To validate and extend these results we inve…
A novel mutation of the DHCR7 gene in a sicilian compound heterozygote with Smith-Lemli-Opitz Syndrome
2005
Introduction: Smith-Lemli-Opitz syndrome (SLOS) is an autosomal recessive disorder of cholesterol biosynthesis, resulting from deficient 7-dehydrocholesterol reductase (3β-hydroxysterol Δ7-reductase) activity, the enzyme responsible for conversion of 7-dehydrocholesterol to cholesterol. SLOS is most common among people of European descent, with a reported incidence of 1 per 20 000–60 000 newborns, depending on the diagnostic criteria and the reference population. More than 80 different mutations have been identified in several hundred patients. In Italy, SLOS appears to be a rare condition, probably because of underdiagnosis. Method: We analyzed by direct sequencing the 7-dehydrocholesterol…
Bleomycin inhibition of DNA synthesis in isolated enzyme systems and in intact cell systems.
1975
Abstract Blcomycin (BLM) inhibits DNA and RNA synthesis in different isolated enzyme systems. The inhibition effect can be reduced by adcling RNA to the reaction mixture. The activity of the RNA dependent DNA polymerase and of a cell-free protein synthesizing system is not affected by BLM. The antibiotic reduces cell proliferation (L5178y mouse lymphoma cells) in vitro at low concentrations by cytostatis and at higher concentrations by cytotoxicity. In BLM-treated L5178y cells DNA synthesis is strongly reduced, while RNA and protein synthesis are not affected. In vivo , using growing quail oviducts, cell proliferation and cytodifferentiation are markedly inhibited after BLM treatment. This …
Adenoids of patients with mucopolysaccharidoses demonstrate typical alterations.
2015
Abstract Objective Tonsillar hypertrophy caused by the progressive accumulation of partially degraded glycosaminoglycans (GAGs) within the cells is a typical symptom in patients with mucopolysaccharidoses (MPS). We studied the tissue of adenoids and tonsils of patients suffering from MPS with special regard to characteristic morphological features serving as possible markers for diagnosis. Methods Adenoids of 87 patients and tonsils of 4 patients with MPS (2 patients with MPS I, 7 MPS II, 5 MPS IV and 10 MPS VI and 63 controls) and controls were examined. Examinations were repeated in a blinded manner by two pathologists. Results The key feature observed was a subepithelial “clearing” on sc…
Subclinical executive function impairment in children with asymptomatic, treated phenylketonuria: A comparison with children with immunodeficiency vi…
2018
In this study we compared the neuropsychological profile of phenylketonuria (PKU) and human immunodeficiency virus (HIV) to examine the specificity of the executive function (EF) impairment reported in these two patologies. A total of 55 age-matched children and adolescents were assessed, including 11 patients with PKU, 16 patients with HIV and 28 healthy controls, underwent a neuropsychological assessment. Although neither the PKU nor the HIV group scored below the normative ranges, both groups showed lower scores in neuropsychological tests engaging EFs than controls. In addition, compared to patients with PKU the HIV group performed significantly worse in the Trail-Making Test A, Corsi S…
Cumulative incidence rates of the mucopolysaccharidoses in Germany
2005
In order to estimate the cumulative incidence rates of the mucopolysaccharidoses (MPS) in Germany, a retrospective epidemiological survey covering the period between 1980 and 1995 was implemented. Multiple ascertainment sources were used to identify affected patients. A prevalence of approximately 0.69 cases per 100,000 births was obtained for MPS I (Hurler phenotype). Within the study period, 4 patients with Hurler/Scheie phenotype and 7 cases with Scheie disease were detected. The cumulative incidence for MPS II (Hunter syndrome) was estimated as 0.64 cases per 100,000 births (1.3 cases per 100,000 male live births); that for MPS III (Sanfilippo syndrome types A, B and C) as 1.57 cases in…
Contribution of Large Genomic Rearrangements in Italian Lynch Syndrome Patients: Characterization of a Novel Alu-Mediated Deletion
2012
Lynch syndrome is associated with germ-line mutations in the DNA mismatch repair (MMR) genes, mainlyMLH1andMSH2. Most of the mutations reported in these genes to date are point mutations, small deletions, and insertions. Large genomic rearrangements in the MMR genes predisposing to Lynch syndrome also occur, but the frequency varies depending on the population studied on average from 5 to 20%. The aim of this study was to examine the contribution of large rearrangements in theMLH1andMSH2genes in a well-characterised series of 63 unrelated Southern Italian Lynch syndrome patients who were negative for pathogenic point mutations in theMLH1,MSH2, andMSH6genes. We identified a large novel delet…
