Objective. To evaluate the association between diabetes mellitus and health-related quality of life (HRQOL) controlled for several sociodemographic and anthropometric variables, in a representative sample of the Spanish population. Methods. A population-based, cross-sectional, and cluster sampling study, with the entire Spanish population as the target population. Five thousand and forty-seven participants (2162/2885 men/women) answered the HRQOL short form 12-questionnaire (SF-12). The physical (PCS-12) and the mental component summary (MCS-12) scores were assessed. Subjects were divided into four groups according to carbohydrate metabolism status: normal, prediabetes, unknown diabetes (UNKDM), and known diabetes (KDM). Logistic regression analyses were conducted. Results. Mean PCS-12/MCS-12 values were 50.9 ± 8.5 / 47.6 ± 10.2, respectively. Men had higher scores than women in both PCS-12 (51.8 ± 7.2 versus 50.3 ± 9.2; P < 0.001) and MCS-12 (50.2 ± 8.5 versus 45.5 ± 10.8; P < 0.001). Increasing age and obesity were associated with a poorer PCS-12 score. In women lower PCS-12 and MCS-12 scores were associated with a higher level of glucose metabolism abnormality (prediabetes and diabetes), (P < 0.0001 for trend), but only the PCS-12 score was associated with altered glucose levels in men (P < 0.001 for trend). The Odds Ratio adjusted for age, body mass index (BMI) and educational level, for a PCS-12 score below the median was 1.62 (CI 95: 1.22.19; P < 0.002) for men with KDM and 1.75 for women with KDM (CI 95: 1.262.43; P < 0.001), respectively. Conclusion. Current study indicates that increasing levels of altered carbohydrate metabolism are accompanied by a trend towards decreasing quality of life, mainly in women, in a representative sample of Spanish population. © Copyright © 2012 C.

Atherosclerosis | Year: 2011

Background: Autosomal dominant hypercholesterolemias (ADHs) are characterised by increased plasma levels of total and LDL cholesterol, predisposing to premature atherosclerosis. ADHs comprise several diseases with undistinguishable phenotype, caused by mutations in different genes: LDLR, APOB and PCSK9. Genetic studies are usually performed in patients with altered cholesterol levels. However, some persons carrying pathogenic mutations are normocholesterolemic and there are no further studies about this subject. We have studied the frequency of families and individuals carrying ADH mutations who do not present the disease in Spanish population. Methods: We have analysed genes known to cause ADH by direct sequencing in 24 ADH families (215 members). Functional effect of some LDLR gene mutations was assessed by transfecting cultured cells with plasmids. Results: Six families with mutations presented 7 mutation carriers who did not show ADH phenotype: 30% of ADH families presented normocholesterolemic individuals, and 7% of carriers of pathogenic mutations did not show ADH phenotype. We have analysed the effect of some of these mutations and they are responsible for impaired LDL receptor function. We have excluded mutations in APOB and PCSK9 genes that could reduce LDLc levels. Conclusions: An important percentage of ADH families presented individuals who do not show an ADH phenotype, but who are able to transmit the pathogenic mutation to their offspring. Genetic study of all subjects in ADH families should be performed in order to identify normocholesterolemic carriers that allow the detection of mutations in their descendants and the prevention of the disease consequences. © 2011 Elsevier Ireland Ltd.

Eur J Clin Invest 2010; 40 (2): 89-94 AbstractBackground Few data are available on circulating mononuclear cells nuclear factor-kappa B (NF-kB) activity and plasma xanthine oxidase (XO) activity in heterozygous familial hypercholesterolaemia (FH). The goal of the study was to analyse circulating mononuclear cells NF-kB and plasma XO activities in FH patients. Materials and methods Thirty FH index patients and 30 normoglycaemic normocholesterolaemic controls matched by age, gender, body mass index, abdominal circumference and homeostasis model assessment index were studied. Plasma XO and inflammatory markers were measured by standard methods. NF-kB was assayed in circulating mononuclear cells. Results Familial hypercholesterolaemia patients showed a significantly higher NF-kB (75·0 ± 20·7 vs. 42·7 ± 16·8 relative luminiscence units) and XO (0·44 ± 0·13 vs. 0·32 ± 0·09 mU mL-1) activities than controls. In addition, interleukin-1, interleukin-6, high sensitivity C reactive protein (hsCRP) and oxidized LDL (LDL-ox) were also significantly higher in FH patients. In the total group (FH and controls), XO was significantly associated with LDL-cholesterol (LDL-C), apolipoprotein B (apoB), NF-kB and hsCPR, and NF-kB activity was significantly associated with XO, hsCPR, LDL-ox, LDL-C and apoB plasma values. Using multiple regression analysis, XO was independently associated with hsCPR and NF-kB, and NF-kB activity in circulating mononuclear cells was independently associated with apoB and LDL-ox plasma values. Conclusion Familial hypercholesterolaemia patients show increased activities of NF-kB and XO, and higher values of low grade inflammatory markers related to atherosclerosis. NF-kB activity was independently associated with apoB plasma values. These data could explain in part the high cardiovascular disease risk present in these patients. © 2009 Stichting European Society for Clinical Investigation Journal Foundation.

Objectives: Between 30 and 50% of the cirrhotic patients who do not show symptoms of clinical hepatic encephalopathy (HE) present minimal hepatic encephalopathy (MHE), with mild cognitive impairment. MHE impairs the quality of life, increases the risk of suffering accidents, predicts the appearance of clinical HE, and is associated with shortened lifespan. Early detection of MHE would be very useful. The gold standard for MHE diagnosis is the psychometric hepatic encephalopathy score (PHES). However, it is time consuming and needs adjusting for age and educational level. It would be very useful to have some blood biomarker reflecting the presence of MHE in cirrhotic patients. The aim of this work was to identify serum molecules useful as biomarkers for MHE. Methods: We measured in 63 controls, 43 cirrhotic patients without MHE, and 44 patients with MHE, from Hospital Clinico de Valencia, serum levels of different amino acids, cyclic guanosine monophosphate (cGMP), nitritesnitrates, and 3-nitrotyrosine. We analyzed for each parameter its diagnostic accuracy as an indicator of MHE, as assessed using the PHES. Results: These studies supported that 3-nitro-tyrosine is a good marker for MHE. To validate its utility as a biomarker for MHE, we analyzed in a second cohort of 44 cirrhotic patients without MHE and 18 patients with MHE, from Hospital Arnau de Vilanova, serum levels of 3-nitro-tyrosine, methionine, and citrulline. Citrulline (173±17%), methionine (173±16%), and 3-nitro-tyrosine (857±92%) were increased in sera from patients with MHE when compared with those without MHE. The receiver operating characteristic (ROC) curve analysis of 3-nitro-tyrosine for the diagnosis of MHE in the first cohort showed an area under the curve (AUC) value of 0.96 (95% confidence interval 0.93-0.99). At the cutoff of 14 nM, the specificity was 93%, sensitivity 89%, and positive and negative predictive values were both 91%. When the same cutoff was applied to the second cohort, the specificity was 83% and sensitivity was 94%. The positive and negative predictive values were 70 and 97%, respectively. Conclusions: This pilot study, to be validated in a larger cohort, shows that determination of 3-nitro-tyrosine in serum, which is easy and not time consuming, is useful to identify patients with MHE, with good sensitivity, specificity, and positive and negative predictive values. © 2011 by the American College of Gastroenterology.
