BACKGROUND The benefits of using the 23-valent pneumococcal polysaccharide vaccine (PPV23) are controversial. This study assessed clinical effectiveness of PPV23 in preventing community-acquired pneumonia (CAP) among the general population aged ≥ 60 years. METHODS This was a population-based cohort study involving 27 204 individuals aged ≥ 60 years in(More)
OBJECTIVE This study assessed incidence, aetiology, clinical outcomes and risk factors for community-acquired pneumonia (CAP) in older adults. METHODS This was a population-based cohort study that included 11,241 community-dwelling individuals aged 65 years or more, who were followed between 2002 and 2005 in the region of Tarragona, Spain. Primary(More)
Although rarely, Arcobacter spp. have been associated with diarrhoea and bacteraemia. We report a persistent case in a healthy 26-year-old Spanish male of bloody diarrhoea, which was attributed to Campylobacter but in fact was caused by Arcobacter cryaerophilus, as determined by sequencing of the rpoB gene. The isolate was re-identified by matrix-assisted(More)
The 23-valent polysaccharide pneumococcal vaccine is currently recommended in elderly and high-risk adults. Its efficacy against invasive pneumococcal disease has been demonstrated, but its effectiveness in preventing pneumonia remains uncertain. This study assessed the clinical effectiveness of vaccination against pneumonia among middle-aged and older(More)
BACKGROUND Pneumococcal diseases remain a major cause of morbidity and mortality worldwide. Updated data on drug-resistance from different populations may be important to recognize changes in disease patterns. This study assessed current levels of penicillin resistance among Streptococcus Pneumoniae causing pneumonia in Spanish middle age and older adults.(More)
The availability of highly active antiretroviral therapy has markedly improved the survival rate and quality of life in patients infected with HIV. At present, however, there is still no cure for HIV and those undergoing treatment have to do so for life. The use of antiretroviral drugs has been associated with several toxicities that limit their success.(More)
During a Spanish surveillance study, two natural variants of DHA β-lactamases, DHA-6 and DHA-7, were found, with the replacements Ala226Thr and Phe322Ser, respectively, with respect to DHA-1. The DHA-6 and DHA-7 enzymes were isolated from Escherichia coli and Enterobacter cloacae clinical isolates, respectively. The aim of this study was to genetically,(More)
Population-based surveillance study conducted among persons 65 years or older from the region of Tarragona (Southern Catalonia, Spain) during 2002-2009. All cases with isolation of pneumococcus from normally sterile bodily fluids were included. Incidence rates of invasive pneumococcal disease (IPD) and prevalence of infections caused by serotypes included(More)
BACKGROUND Pneumococcal infections remain a major health problem worldwide. This study analysed the distribution of distinct Streptococcus pneumoniae serotypes causing invasive pneumococcal disease (IPD) among all-age population in the region of Tarragona (Spain) throughout 2006-2009. METHODS An amount of 237 strains were evaluated, of which 203 (85.7%)(More)
