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…

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…

Multicenter, double-blind, randomized, intraindividual crossover comparison of gadobenate dimeglumine and gadopentetate dimeglumine for Breast MR ima…

2011

To intraindividually compare 0.1 mmol/kg doses of gadobenate dimeglumine and gadopentetate dimeglumine for contrast material-enhanced breast magnetic resonance (MR) imaging by using a prospective, multicenter double-blind, randomized protocol.Institutional review board approval and patient informed consent were obtained. One hundred sixty-two women (mean age, 52.8 years ± 12.3 [standard deviation]) enrolled at 17 sites in Europe and China between July 2007 and May 2009 underwent at least one breast MR imaging examination at 1.5 T by using three-dimensional spoiled gradient-echo sequences. Of these, 151 women received both contrast agents in randomized order in otherwise identical examinatio…

Prevalence of Helicobacter pylori infection and atrophic gastritis in Latvia.

2012

Helicobacter pylori infection and atrophic gastritis are related to an increased risk for gastric cancer. There is a decrease in global H. pylori prevalence. We analyzed the prevalence of H. pylori infection in Latvia by the plasma IgG test and the presence of atrophy by means of pepsinogen testing.This subanalysis was carried out on a randomly selected cross-sectional sample of a general population of adults to access cardiovascular risk factors. Plasma samples were screened for H. pylori IgG (cutoff value 24 U/ml), and pepsinogens (Pg) I and II. Pg cutoff values of PgI/PgII ≤ 3 and PgI ≤ 70 ng/ml were used to assess the prevalence of atrophy of any grade and PgI/PgII ≤ 2 and PgI ≤ 30 ng/m…

Association analysis of SCN9A gene variants with borderline personality disorder

2008

Borderline personality disorder (BPD) is a serious psychiatric disorder affecting about 1-2% of the general population. Key features of BPD are emotional instability, strong impulsivity, repeated self-injurious behavior (SIB) and dissociation. In the etiology of BPD and its predominant symptoms, genetic factors have been suggested. The voltage-gated sodium channel Nav1.7 is expressed in sensory neurons and in the hippocampus, a key region of the limbic system probably dysfunctional in BPD and dissociative disorders. The alpha-subunit of Nav1.7 is encoded by the SCN9A gene on chromosome 2 and variations of SCN9A can lead to complete inability to sense pain. The aim of the present study was t…

Heterogeneity of obesity-asthma association disentangled by latent class analysis, the SAPALDIA cohort

2017

Although evidence for the heterogeneity of asthma accumulated, consensus for definitions of asthma phenotypes is still lacking. Obesity may have heterogeneous effects on various asthma phenotypes. We aimed to distinguish asthma phenotypes by latent class analysis and to investigate their associations with different obesity parameters in adults using a population-based Swiss cohort (SAPALDIA). We applied latent class analysis to 959 self-reported asthmatics using information on disease activity, atopy, and age of onset. Associations with obesity were examined by multinomial logistic regression, after adjustments for age, sex, smoking status, educational level, and study centre. Body mass ind…

The effects of indoor cycling training in sedentary overweight women

2010

Abstract AIM: The aim of this study was to evaluate the body composition and physiological effects in young sedentary overweight women after an indoor cycle training period. METHODS: Fourteen subjects (22.6+/-2.1 yrs; 25-29.9 BMI) were trained for 12 weeks in a specific indoor cycling protocol (ICP) consisting of three sessions/week carried out in a fitness room. Body composition and physiological parameters were taken before the beginning of the study and after 12, 24 and 36 sessions. RESULTS: We observed a reduction of 2.6% and 3.2% in body weight and of 4.3% and 5% in fat mass after 24 and 36 sessions respectively (P<0.05). Lean mass increased by 2.3% and 2.6% respectively after 24 and 3…

Circulating levels of adipose products and differences in fat distribution in the ovulatory and anovulatory phenotypes of polycystic ovary syndrome.

2009

Central fat distribution is increased in anovulatory women with polycystic ovary syndrome (PCOS) compared with ovulatory PCOS and matched controls. Among secreted adipocytokines, this is reflected mainly in lower levels of adiponectin.

Diagnosis of Liver Cirrhosis

2005

Background/goals Liver cirrhosis, the final stage of chronic liver disease, is characterized by an unfavorable prognosis and an increased risk of hepatocellular carcinoma and also requires an appropriate management. Laparoscopy, the gold standard in the diagnosis of cirrhosis, is hampered by its invasiveness. Therefore, a noninvasive method for diagnosing liver cirrhosis would be of great benefit. Study A consecutive series of 100 patients, sent to our gastroenterological unit for diagnostic laparoscopy, underwent a standardized ultrasonographic examination prior to laparoscopy. Results Conventional ultrasonographic examination revealed a sensitivity of 55% and a specificity of 86% in the d…
