    Serum biomarkers in uncontrolled no heart-beating donors may identify kidneys that will never work after transplantation
    (Springer, 2016-07-01) López Farre, Antonio José; Santos Sancho, Juana María; Modrego, Javier; Zamorano León, José Javier; Martín, Leyre; Sánchez Fructuoso, Ana Isabel; Rodríguez Sierra, Pablo; Herrero Calvo, José Antonio; Río Gallegos, Francisco José Del; Barrientos Alberto; Barrientos Guzmán, Alberto
    Background/aims Kidneys from uncontrolled non heart-beating donors achieve a good level of renal function after transplantation. However, a number of them will never function in the recipient. Our aim was to determine if serum biomarkers associated with platelet activity, inflammation and the nitric oxide system in uncontrolled non heart-beating donors may help to predict no renal function recovery after renal transplantation. Methods Serum levels of interleukin (IL)-6, IL-10, intercellular cell adhesion molecule-1 (ICAM-1), cyclic guanosine monophosphate (cGMP), nitrite + nitrate and platelet factor-4 (PF4) were measured using enzyme-linked immunosorbent assay (ELISA) kits in 88 uncontrolled non heart-beating donors divided according to the renal functionality achieved in the recipients into functional (n = 76) and non functional (n = 12). Results Kidneys from donors with higher IL-6 levels (>900 pg/ml) were functional after transplantation. Serum cGMP levels below 372.3 fmol/l were also associated with kidneys that recovered the renal function. However, serum levels of PF4 showed the best correlation with recovery of renal functional in the recipients since they were significantly lower in the donors whose kidneys functioned after transplantation. Conclusions Serum PF4 levels in uncontrolled non heart-beating donors may be a good predictor for kidneys that never will reach functional recovery. Some serum cGMP, IL-6 and IL-10 levels may simply help identify kidneys that will function after transplantation.

    New circulating biomarkers for predicting cardiovascular death in healthy population
    (Wiley Open Access, 2015-07-01) Olle, Melander; Modrego, Javier; Zamorano León, José Javier; Santos Sancho, Juana María; Lahera Julia, Vicente; López Farre, Antonio José
    There is interest to analyse newer biomarkers to identify healthy individuals at risk to develop cardiovascular disease (CVD) incidents and death. To determine in healthy individuals new circulating protein biomarkers, whose systemic levels may be associated with the risk of future development of CVD incidents and death. The study was performed in 82 individuals from the Malm€o Diet and Cancer study cohort, free from CVD of whom 41 developed CVD and 41 did not. Plasma proteins related to inflammation and thrombo-coagulating processes were analysed. a1-antitrypsin isotype 3 plasma levels were significantly higher while apolipoprotein J plasma levels were lower in participants that developed CVD incidents than those that did not develop acute cardiovascular episode. Of 82 participants, 17 died by CVD causes. There were proteins whose expression in plasma was significantly higher in participants suffering CVD death as compared with those that did not die by CVD. These proteins included: fibrinogen b-chain isotypes 1 and 3, fibrinogen-c-chain isotype 2, vitamin D-binding protein isotypes 1, 2 and 3, a1-antitrypsin isotypes 3 and 6, haptoglobin isotypes 3,4,5 and 5, haemopexin isotypes 1 and 2, and Rho/Rac guanine nucleotide exchange factor 2. Moreover, apolipoprotein J plasma levels were found lower in participants that died by cardiovascular cause. Association between plasma levels of proteins and CVD death was independent of age, gender, conventional risk factors and plasma C-reactive protein levels. Several protein plasma levels and protein isotypes related to inflammation and thrombo-coagulating phenomena were independently associated with the risk of future CVD death.

    Sports facilities, socio-economic context and overweight among the childhood population in two southern European cities: a cross sectional study
    (BMC, 2019-09-03) Albaladejo Vicente, Romana; Villanueva Orbaiz, M. Rosa Rita; Astasio Arbiza, Paloma; Ortega Molina, Soledad Paloma; Santos Sancho, Juana María; Regidor Poyatos, Enrique
    Background: To evaluate relationship between socio-economic environment and overweight in Madrid and Barcelona, adjusting for possible confounding factors. Methods: We obtained three indicators which reflected socio-economic context, namely, unemployment rate, percentage of population with tertiary education, and percentage with a second home. The design is a cross sectional study. The association with overweight was estimated using odds ratios by multilevel logistic regression. The statistical analysis, data synthesis, or model creation was performed from the 2017. In all, 707 children from 21 districts of Madrid and 474 children from 10 districts of Barcelona were analysed. Results: In Madrid, standardised ORs for personal and family characteristics were 1.17, 1.53 and 1.57 by reference to unemployment rate and percentages of population with a university education and second home. After adjustment, only the OR obtained with unemployment rate decreased, specifically by 58%. In Barcelona, the following ORs were obtained: 1.80 with unemployment rate; 1.80 with population having a university education; and 1.86 with population having a second home. After being standardised, these ORs decreased by 14% in the case of unemployment rate, 10% in the case of population with a university education, and 9% in the case of population with a second home. Conclusions: Overweight displayed a risk gradient in Madrid and Barcelona alike. This risk of overweight is not accounted for by physical inactivity and could, in part, be due to the availability of sports facilities.

    BRCA2 gene mutations and coagulation-associated biomarkers
    (Thieme Gruppe, 2015-07-01) Pérez Segura, Pedro; Zamorano León, José Javier; Acosta, Daniel; Santos Sancho, Juana María; Modrego, Javier; Caldés, Trinidad; de la Hoya, Miguel; Díaz-Rubio García, Eduardo; Díaz Millán, Isabel; Heras Jiménez, Natalia De Las; Rico Zalba, Luis; Lahera Julia, Vicente; Melander, Olle; López Farre, Antonio José
    Thromboembolic events are the second cause of death in cancer patients, although the mechanisms underlying this increased thromboembolic risk remain unclear. The aims of this study were to examine whether BRCA2 gene mutations may modify the circulating levels of thrombocoagulation biomarkers and whether breast cancer development may influence changes in such circulating biomarkers. The study was performed in 25 women with mutations in the BRCA2 gene (n=12 breast cancer, n=13 breast cancer-free) and in 13 BRCA2 non-mutant controls. Results revealed that plasma levels of fibrinogen gamma chain isotypes 2 and 3, haptoglobin isotypes 4 and 5, serotransferrin isotypes 3 and 4 and convertase C3/C5 isotypes 4 and 5 were significantly higher in BRCA2 mutation carriers compared to controls. However, plasma levels of vitamin D binding protein isotype 1 and alpha1-antitrypsin isotypes 2, 3 and 4 were significantly decreased in BRCA2 mutation carriers compared to controls. Plasma expression of PF4 and P-selectin was significantly higher in BRCA2 mutations carriers than in controls. BRCA2 truncated mutations conserving a binding region for RAD51 were associated with increased plasma levels of alpha1-antitrypsin isotypes 3 and 4 with respect to women showing BRCA2 mutations that loss the binding RD51 region to BRCA2. Only plasma levels of vitamin D binding protein isotypes 1 and 3 were significantly reduced and alpha 1-antitrypsin isotype 1 was increased in cancer-free BRCA2 mutation carriers compared to BRCA2 mutation carriers with breast cancer. The presence of BRCA2 mutations is associated with increased plasma levels of thrombo-coagulating-related proteins, which are independent to breast cancer development.
