Further evaluation of plasma sphingomyelin levels as a risk factor for coronary artery disease

2006

Abstract Background Sphingomyelin (SM) is the major phospholipid in cell membranes and in lipoproteins. In human plasma, SM is mainly found in atherogenic lipoproteins; thus, high levels of SM may promote atherogenesis. Methods We investigated in a median follow up of 6.0 years the association of SM with the incidence of a combined endpoint (myocardial infarction and cardiovascular death) in stable and unstable patients, and its relation to other marker of atherosclerosis in 1,102 patients with angiographically documented CAD and 444 healthy controls. Results and discussion Logistic regression analysis showed that SM categorized by median was associated with an elevated risk for CAD (HR 3.2…

Iron deficiency and long-term mortality in elderly patients with acute coronary syndrome.

2018

Aim: We evaluated the relationship between iron deficiency (ID) and long-term mortality risk in elderly patients with acute coronary syndrome (ACS). Methods: In this prospective observational study, we included 252 patients older than 65 years with ACS. Transferrin saturation (TSAT) and ferritin were collected before discharge. Results: Mean age, hemoglobin and GRACE score were 78 ± 7 years, 12.4 ± 1.8 g/dl and 138.8 ± 25.3, respectively, 112(44.4%) patients were women, and 151(59.9%) presented ID. During the follow-up, 121 (48%) patients died. Mortality rates among TSAT quartiles were: 2.38, 1.60, 0.90 and 0.95 × 10 person-years for Q1TSAT to Q4TSAT, respectively (p < 0.001) and did no…

Hereditary Angioedema: Increased Number of Attacks after Frequent Treatments with C1 Inhibitor Concentrate

2009

OBJECTIVE: C1 inhibitor concentrate is regarded as effective and safe in treating acute attacks of hereditary angioedema caused by C1 inhibitor deficiency. This study investigated the course of disease in 3 women treated frequently with C1 inhibitor concentrate. METHODS: Three women are described who received C1 inhibitor concentrate for the treatment of acute attacks of hereditary angioedema and experienced an increase in the frequency of attacks during that treatment period. In a control group of 24 patients aged more than 60 years with hereditary angioedema, the natural course of disease was determined. RESULTS: The 3 women (ages 50, 69, and 72 years) had received C1 inhibitor concentrat…

LSC Abstract – Increased oxidative stress leads to telomere shortening in children with alpha-1 antitrypsin deficiency

2016

Background: Oxidative stress (OS) is involved in the pathophysiology of AATD (Escribano A. et al. Thorax 2015; 70:82-3). In addition, it has been shown that OS accelerates telomere shortening which is associated to higher emphysema risk in COPD patients. Rationale and aims: Since AATD is characterised by chronic OS, we hypothesise that telomere shortening would be accelerated in AATD patients and would be associated with higher risk of developing lung disease. This study is aimed to assess the OS profile, the enzymatic antioxidant defence mechanisms and telomere length (TL) in children with AATD and to study its association with AAT phenotypes. Methods: OS parameters, the activity of the ma…

The L-glutamate transporters GLAST (EAAT1) and GLT-1 (EAAT2): expression and regulation in rat lactating mammary gland.

1999

The Na(+)-dependent L-glutamate transporters GLAST (EAAT1) and GLT-1 (EAAT2), were expressed in rat lactating mammary gland, but EAAC1 (EAAT3) was not. GLT-1 expression in rat lactating mammary gland was constant in all the physiological situations studied; however, the GLAST expression is under tight regulation. Fasting for 24 h decreased the GLAST expression which returned to control values after refeeding. Weaning for 24 h produced a decrease in GLAST expression through a mechanism independent of prolactin deficiency. Resuckling for 6 h returned the expression of this transporter to control values. There is a correlation between the levels of GLAST (mRNA and protein) and the in vivo upta…

The implementation of pre-exposure prophylaxis in Spain without women

2018

El objetivo del presente artículo es la exposición sucinta de la exclusión de las mujeres en la resolución del 27 de Julio de 2017 en el que se explicita el convenio de colaboración entre la Dirección General de Salud Pública, Calidad e Innovación y la empresa Gilead Servicios S.L.U. Este convenio es la formalización de la entrada e implementación de la profilaxis preexposición ante el VIH en el territorio nacional. La profilaxis preexposición ante el VIH es una novedosa intervención biomédica de carácter preventivo aplicada en personas que no viven con el VIH, que contiene como parte fundamental la ingesta diaria de un medicamento llamado Truvada, formado por dos componentes farmacológicos…

Hereditary Angioedema Due to C1 Inhibitor Deficiency: New Findings Concerning Symptoms and Affected Organs

Aszites und vermeintliches akutes Abdomen bei hereditärem Angioödem durch C1-Inhibitor-Mangel

2008

HISTORY AND CLINICAL FINDINGS A 35-year-old man, for 8 years known to have hereditary angio-oedema with recurrent cutaneous swellings and occasional attacks of gastrointestinal pain, developed very painful, colic-like upper abdominal symptoms and frequent vomiting. INVESTIGATIONS Routine laboratory tests were normal, except for leucocytosis of 18,200 WBC/microliter. The plasma concentrations of C1-esterase inhibitor (5.6 mg/dl) and of complement factor C4 (10.0 mg/dl) were reduced. Computed tomography revealed about 500 ml free fluid, a perihepatic effusion and definite oedematous thickening of the ileal wall. TREATMENT AND COURSE During conservative treatment with infusions and no food by …
