OBJECTIVES To determine the population-based incidence of community-acquired pneumonia (CAP) in adults and to assess the relative importance of age and gender on the incidence of infections caused by different microbial pathogens. METHODS A two-year prospective study in a well-defined geographic area of the Spanish Mediterranean coast. RESULTS The(More)
In 1989, our medical center used continuous quality improvement concepts in the creation of a Nosocomial Pneumonia Prevention Team whose aim was to significantly reduce nosocomial ventilator-associated pneumonia. The team included representatives from nursing, respiratory therapy, pulmonary medicine, internal medicine, anesthesiology, education and(More)
BACKGROUND Data on long-term central nervous system (CNS) toxicity associated with efavirenz therapy are scarce, and risk factors remain largely unknown. We aimed to determine whether monitoring the plasma concentration of efavirenz could predict neuropsychiatric adverse events associated with long-term therapy with efavirenz. METHODS We performed a(More)
STUDY OBJECTIVES To evaluate the usefulness of procalcitonin serum levels as a predictor of etiology and prognosis in adult patients with community-acquired pneumonia (CAP) when they are stratified according to severity. DESIGN One-year, population-based, prospective study. SETTING University teaching hospital. PATIENTS All adult patients who received(More)
Coenzyme Q (Q) is an essential component of the mitochondrial respiratory chain in eukaryotic cells but also is present in other cellular membranes where it acts as an antioxidant. Because Q synthesis machinery in Saccharomyces cerevisiae is located in the mitochondria, the intracellular distribution of Q indicates the existence of intracellular Q(More)
To describe characteristics and prognosis of patients with suboptimal immunological response to combined antiretroviral therapy (CART). Using data from a multicenter cohort study, we selected patients who initiated CART and showed suboptimal CD4-T cell response (defined as <50 cells/L increase) after 1 year of therapy, despite sustained virological(More)
Initiation of combined antiretroviral therapy (cART) is associated with bone loss, which may be more intense with regimens including tenofovir. The underlying mechanisms are not well understood. Cross-sectional data have linked tenofovir with higher parathyroid hormone (PTH) concentrations in patients with vitamin D deficiency. We performed a longitudinal(More)
Mycobacteria other than tuberculosis infections in patients taking various tumour necrosis factor (TNF)-alpha inhibitors have been reported in the literature. We describe sporotrichoid spread of Mycobacterium marinum in a man with Crohn's disease treated with infliximab. After starting ethambutol and rifampicin and discontinuing infliximab, a worsening(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)
C-reactive protein (CRP) has been associated with prognosis of HIV-infection, but its relationship with cardiovascular disease remains unknown. We aimed to evaluate whether CRP may be a marker of cardiovascular risk in HIV-infected patients, and to determine the influence of antiretroviral therapy (ART) on CRP levels. We conducted a cross-sectional study on(More)
