BACKGROUND Diagnosis and treatment of latent tuberculosis infection (LTBI) is the most effective strategy to control tuberculosis (TB) among patients with HIV infection. The tuberculin skin test (TST) was the only available method to identify LTBI. The aim of the present work was to evaluate the usefulness of the interferon-gamma release assays (IGRAs):(More)
BACKGROUND Limited information exists on long-term prognosis of patients with sustained virologic response to antiretroviral therapy. We aimed to assess predictors of unfavorable clinical outcome in patients who maintain viral suppression with HAART. METHODS Using data collected from ten clinic-based cohorts in Spain, we selected all antiretroviral-naive(More)
BACKGROUND Relationship of hepatitis C virus (HCV) infection with an increased risk of cardiovascular disease (CVD) in HIV-infected patients remains controversial. We evaluated endothelial function and subclinical atherosclerosis in HIV-infected patients with and without HCV. METHODS Flow-mediated dilatation (FMD) of the brachial artery and circulating(More)
BACKGROUND To report the clinical and epidemiological characteristics of hepatocellular carcinoma (HCC) diagnosed in a cohort of human immunodeficiency virus (HIV)-infected patients in Spain. METHODS All HIV-infected patients diagnosed of HCC in 18 hospitals in Spain before 31 December 2010 were included. The main characteristics of HCC cases are(More)
OBJECTIVES Raltegravir has been demonstrated to have a favourable impact on several metabolic parameters, including a lack of changes in lipid and glucose concentrations. We aimed to assess the effect on endothelial function of switching from a ritonavir-boosted protease inhibitor (PI/r)-based regimen to raltegravir. METHODS This is a substudy of the(More)
Human infection with Rickettsia sibirica mongolitimonae was initially reported in 1996, and reports of a total of 18 cases have been published. We describe 6 additional cases that occurred in the Mediterranean coast region of Spain during 2007-2011. Clinicians should consider this infection in patients who have traveled to this area.
We conducted a systematic investigation of pneumococcal co-infection in patients with a diagnosis of pandemic (H1N1) 2009 and any risk factor for complications or with severity criteria. We found 14% prevalence, with one third of patients having nonpneumonic infections. A severity assessment score >1 and high C-reactive protein levels were predictors of(More)
OBJECTIVE We aimed to assess whether oxidative stress is a predictor of mortality in HIV-infected patients. METHODS We conducted a nested case-control study in CoRIS, a contemporary, multicentre cohort of HIV-infected patients, antiretroviral-naïve at entry, launched in 2004. Cases were patients who died with available stored plasma samples collected. Two(More)
Community-acquired pneumonia (CAP) is a major cause of morbidity and mortality. However, identification of the infecting organism is achievable in only 40 –50% of cases, and results are not usually available when the diagnosis of pneumonia is first established (1, 2). Therefore, initial therapy is typically empirical, usually aimed at the standard bacteria,(More)
Although different factors have been implicated in the CD4/CD8 T-cell ratio recovery in HIV-infected patients who receive effective antiretroviral therapy (ART), limited information exists on the influence of the regimen composition. A longitudinal study carried out in a prospective, single-center cohort of HIV-infected patients. ART regimens including(More)
