RDW in patients with systemic lupus erythematosus. Influence of anaemia and inflammatory markers
2013
Red blood cell distribution width (RDW) is a routine parameter that reflects size variations in erythrocytes. High RDW has been associated with cardiovascular events and inflammatory diseases. However, no studies evaluating the association of RDW with systemic lupus erythematosus (SLE) have been published. We aimed to explore the association of RDW with inflammatory markers in SLE. As SLE is often associated with anaemia, we considered this factor in order to know whether RDW is related with inflammation, anaemia or both in SLE. The study included 105 SLE patients (7 men, 98 women; aged 15-73 years) and 105 controls (9 men, 96 women; aged 18-71 years). Patients were divided according to ana…
Red blood cell distribution width is not related with inflammatory parameters in morbidly obese patients
2013
Red blood cell distribution width (RDW) is a hematological parameter that has been studied in several clinical settings and has been found to be related to both anemia and inflammatory status. As obesity is related to increased inflammatory pattern, we aimed to analyze the RDW in this setting.We determined hematological and inflammatory parameters in morbidly obese patients before bariatric surgery (n=142) and normo-weight controls (n=144).RDW was higher in patients than in controls (p0.001), along with C-reactive protein (p0.001) and fibrinogen, (p0.001) while hemoglobin (p=0.026), serum iron (p0.001), MCH (p=0.002) and MCHC (p0.001) were lower in morbidly obese patients. The logistic corr…
Vitamin B12 and hepatic enzyme serum levels correlate in male alcohol-dependent patients.
2001
- Vitamin B12 serum levels and markers for alcohol consumption were determined in 80 male alcohol-dependent patients. Spearman correlation coefficients (r(S)) were calculated. Significant positive correlations between vitamin B12 and hepatic enzyme values were found (gamma-glutamyltransferase: r(S) = 0.58; alanine aminotransferase: r(S) = 0.43; aspartate aminotransferase: r(S) = 0.47; glutamate dehydrogenase: r(S) = 0.43; all P:0.001). Therefore, for a proper interpretation of vitamin B12 levels, it may be clinically relevant to take markers of hepatocellular damage into account.
α-Thalassemia Does Not Seem to Influence Erythrocyte Deformability in Sickle Cell Trait Carriers
2014
Studies dealing with rheological red blood cell (RBC) behavior in sickle cell trait carriers are scarce. Moreover, the association with α-thalassemia (α-thal), which also modifies erythrocyte behavior, has not always been taken into account. We analyzed erythrocyte deformability by means of a shear stress diffractometer, along with hematological and biochemical parameters (glucose and plasma lipids), given their possible influence on erythrocyte deformability, in 14 sickle cell trait carriers and 23 healthy controls. Nine patients were also α-thal carriers and five were not. Among the thalassemia carriers, eight were heterozygous and one was homozygous. When compared with controls, sickle c…
Influence of inflammatory and lipidic parameters on red blood cell distribution width in a healthy population
2015
Red blood cell distribution width (RDW) is a routine red blood cell count parameter which has been shown to be associated with inflammatory parameters. Recently, some authors proposed that RDW seems to be a marker of an adverse lipidic profile. In order to clarify whether RDW is related to inflammation, plasma lipids, or both, we determined anthropometric, hematimetric, inflammatory and lipidic parameters in 1111 healthy subjects. RDW correlated directly with age, body mass index (BMI), inflammatory parameters (plasma viscosity, erythrocyte sedimentation rate (ESR), fibrinogen, leukocyte and neutrophil count), and inversely with iron and hematimetric parameters (P 0.05). When subjects were…
Presence of immunoglobulins, C3 and cytolytic C5b-9 complement components on the surface of erythrocytes from patients with β-thalassaemia/HbE disease
1997
The occurrence of IgG, IgM, IgA, C3 and C5b-9 complement complexes on erythrocytes from 43 patients with beta-thalassaemia HbE disease was investigated. Indirect immunoradiometric assays using radioiodinated protein A were employed to quantify the individual components. We confirmed that circulating erythrocytes from thalassaemic patients contained elevated amounts of IgG, and small but significant amounts of C3. In addition, small but significant amounts of C5b-9 were detected. Levels of cell-bound IgG, C3 and C5b-9 were higher in splenectomized versus non-splenectomized patients. The presence of C5b-9 on circulating cells from five splenectomized patients was confirmed by an ELISA employi…
Prenatal mercury exposure in a multicenter cohort study in Spain
2011
Background: Mercury is a ubiquitous heavy metal that may negatively affect human health. It is desirable to investigate mercury exposure in vulnerable populations. Objective: To determine the concentrations of total mercury (T-Hg) in cord blood and to evaluate the role of maternal fish consumption in a Spanish mother and child cohort. Methods: A total of 1883 mother and child pairs from a population-based cohort were included between 2004 and 2008. T-Hg concentrations were measured in whole cord blood and maternal seafood consumption was ascertained by means of a food-frequency questionnaire. Linear regression was used in stratified analyses, while a joint model was adjusted using a mixed-e…
The Adverse Events and Hemodynamic Effects of Adenosine-Based Cardiac MRI
2011
OBJECTIVE We wanted to prospectively assess the adverse events and hemodynamic effects associated with an intravenous adenosine infusion in patients with suspected or known coronary artery disease and who were undergoing cardiac MRI. MATERIALS AND METHODS One hundred and sixty-eight patients (64 ± 9 years) received adenosine (140 µg/kg/min) during cardiac MRI. Before and during the administration, the heart rate, systemic blood pressure, and oxygen saturation were monitored using a MRI-compatible system. We documented any signs and symptoms of potential adverse events. RESULTS In total, 47 out of 168 patients (28%) experienced adverse effects, which were mostly mild or moderate. In 13 patie…
Chronic Thromboembolic Pulmonary Hypertension: Pre- and Postoperative Assessment with Breath-hold MR Imaging Techniques
2004
To evaluate the potential of breath-hold magnetic resonance (MR) imaging techniques in morphologic and functional assessment of patients with chronic thromboembolic pulmonary hypertension (CTEPH) before and after surgery.Thirty-four patients with CTEPH were examined before and after pulmonary thromboendarterectomy (PTE). For morphologic assessment, contrast material-enhanced MR angiography was used; for assessment of hemodynamics, velocity-encoded gradient-echo sequences and cine gradient-echo sequences along the short axis of the heart were performed. Contrast-enhanced MR angiography was compared with selective digital subtraction angiography (DSA) for depiction of central thromboembolic m…
Magnetically labeled water perfusion imaging of the uterine arteries and of normal and malignant cervical tissue: initial experiences.
1998
Purpose: The aim of this pilot study was to evaluate a magnetically labeled water perfusion imaging technique as a non-contrast-enhanced approach to demonstrate the uterine artery, its branches, and to assess the cervical uterine blood flow in healthy volunteers and in patients with advanced uterine cervical carcinoma (FIGO IIB-IVA). Methods and Materials: Seven healthy volunteers (mean age, 29 years) and twenty-two patients (mean age, 52 years) with advanced cancer of the uterine cervix (FIGO IIB-IVA) were prospectively examined by magnetically labeled water perfusion imaging at different inversion delay times (300–900 ms). The magnetic resonance imaging (MRI) findings of all patients were…
