Interventions to decrease short-term peripheral venous catheter-related bloodstream infections: impact on incidence and mortality.

BACKGROUND: Short-term peripheral venous catheters are a significant source of healthcare-acquired bloodstream infections and a preventable cause of death. AIM: To assess the effectiveness of interventions applied to reduce the incidence and mortality associated with short-term peripheral venous catheter-related bloodstream infections (PVCR-BSIs). METHODS: The intervention included continuous PVCR-BSI surveillance, implementation of preventive measures related to catheter insertion and maintenance in accordance with evidence-based recommendations and the hospital's own data, front-line staff educational campaigns, and assessment of adherence to hospital guidelines by ward rounds. A Poisson regression model was used to estimate the trend of rate per year. FINDINGS: From January 2003 to December 2016, 227 episodes of PVCR-BSI were identified among hospitalized patients at a university hospital. The mean age of patients was 67 years (standard deviation 14 years), 69% were male and the median Charlson score was 3 (interquartile range 2-5). Staphylococcus aureus caused 115 (50.7%) episodes. Thirty-day mortality was 13.2%. After implementation of the intervention, the incidence of PVCR-BSIs decreased significantly from 30 episodes in 2003 (1.17 episodes/10,000 patient-days) to eight episodes in 2016 (0.36/10,000 patient-days). The number of episodes caused by S. aureus decreased from 18 episodes in 2003 (0.70/10,000 patient-days) to three episodes in 2016 (0.14/10,000 patient-day), and mortality decreased from seven cases in 2003 (0.27/10,000 patient-days) to zero cases in 2016 (0.00/10,000 patient-days). CONCLUSIONS: Surveillance, implementation of a multi-modal strategy and periodical assessment of healthcare workers' adherence to hospital guidelines led to a sustained reduction in PVCR-BSIs. This reduction had a major impact on S. aureus BSI rates and associated mortality.

Mortality risk factors among non-ICU patients with nosocomial vascular catheter-related bloodstream infections: a prospective cohort study.

BACKGROUND: Vascular catheter-related bloodstream infections (CRBSIs) are highly preventable hospital-acquired infections and a major threat to patient safety. While there is significant information regarding CRBSI outcome among intensive care unit (ICU) patients, data regarding non-ICU patients are scarce. AIM: To determine the risk factors associated with 30-day mortality among non-ICU patients with nosocomial CRBSIs. METHODS: Prospective cohort study of non-ICU patients with nosocomial CRBSIs in a tertiary care centre between January 2004 and December 2014. The primary outcome was 30-day mortality, defined as death from any cause within 30 days of CRBSI. Follow-up was performed 30 days after CRBSI onset. Time until death was the dependent variable in Cox regression analysis. FINDINGS: In total, 546 cases of CRBSI were identified. The mean age of patients was 64.5 years [interquartile range (IQR) 55-75 years], 66% were male, and the mean Charlson score was 3.59 (IQR 2-5). Of the 546 cases, 58.4% resulted from central venous catheters and 41.6% from peripheral venous catheters. The causative agents were Gram-positive cocci (70.1% of cases), Gram-negative bacilli (31.1%) and Candida spp. (1%). Mortality within 30 days was 13.9%, with no significant changes over the study period. Independent risk factors for 30-day mortality were Charlson score ≥4 [hazard ratio (HR) 1.80, 95% confidence interval (CI) 1.19-2.73], Staphylococcus aureus infection (HR 2.67, 95% CI 1.61-4.43) and Candida spp. infection (HR 6.1, 95% CI 2.08-18.04). Age; area of admission; type, use and site of vascular catheter; and administration of appropriate empirical antibiotic treatment were not independent risk factors for 30-day mortality. CONCLUSION: Nosocomial CRBSIs outside ICUs are associated with high risk of mortality, particularly among patients with a higher Charlson score and bloodstream infections caused by Staphylococcus aureus and Candida spp.

Polymicrobial pneumococcal bacteraemia: a case-control study.

Polymicrobial bacteraemia involving Streptococcus pneumoniae and other bacteria (e.g. Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa, Haemophilus influenza, viridans streptococci, Salmonella spp.) occurred in 3.4% of our pneumococcal bacteraemia cases. Compared with 308 controls (monomicrobial bacteraemia), the 77 polymicrobial cases included more males (83 vs 62%, p = 0.001), had serious underlying diseases (100 vs 80%, p < 0.001), abdominal infection (18 vs 5%, p < 0.001), nosocomial infection (33 vs 8%, p < 0.001), shock (40 vs 13%, p < 0.001), and higher mortality (52 vs 18%, p < 0.001). Clinicians must be aware that some patients with pneumococcal bacteraemia may have other bacteria in their blood, which would confer higher mortality and may lead to inappropriate or incomplete antibiotic therapy.

Hypervirulent Klebsiella pneumoniae clones causing bacteraemia in adults in a teaching hospital in Barcelona, Spain (2007-2013).

Virulent hypermucoviscous Klebsiella pneumoniae strains associated with the magA and rmpA genes have mainly emerged in Asia. We analysed the frequency and the clinical and molecular epidemiology of K. pneumoniae bacteraemia isolates obtained over a 7-year period (2007-2013). Fifty-three of 878 K. pneumoniae invasive isolates (5.4%) showed a hypermucoviscous phenotype (by the string test). Of these, 16 (30.2%) were magA(+)/rmpA(+), 12 (22.6%) were magA(-)/rmpA(+), and the remaining 25 (47.2%) were magA(-)/rmpA(-). After multilocus sequence typing and wzi sequencing, all magA(+)/rmpA(+) isolates were serotype K1 and sequence type (ST)23. Of the 12 magA(-)/rmpA(+) isolates, nine were K2 (ST380, ST86, ST65, ST25 and ST493), and three magA(-)/rmpA(+) isolates had the new wzi allele 122, an unknown serotype, and the new ST1013. The remaining isolates, which were magA(-)/rmpA(-), showed different serotypes and STs. Patients with magA(+)/rmpA(+) or magA(-)/rmpA(+)K. pneumoniae bacteraemia more frequently had pyogenic liver abscesses (PLAs) and pneumonia than patients with magA(-)/rmpA(-)K. pneumoniae bacteraemia (respectively: 21.4% vs. 8%, p 0.26; and 17.9% vs. 0%, p 0.05). In fact, magA(-)/rmpA(-) isolates were similar to the those termed 'classic' K. pneumoniae isolates causing bacteraemia, the urinary and biliary tracts being the main foci of infection. In conclusion, hypervirulent clones (CC23K1, CC86K2, CC65K2, and CC380K2) were infrequent among K. pneumoniae isolates causing bacteraemia in our geographical area. A hypermucoviscous phenotype as determined with the string test is not enough to recognize these clones; additional molecular studies are needed. Patients with magA(+) and/or rmpA(+)K. pneumoniae bacteraemia more frequently had PLAs and pneumonia than patients without hypermucoviscosity genes.

The changing epidemiology of bacteraemic osteoarticular infections in the early 21st century.

Osteoarticular infections (OAI), which are often associated with bacteraemia, seem to be increasing. We studied all patients with bacteraemia and concomitant OAI: septic arthritis (SA), vertebral osteomyelitis (VOM) or peripheral osteomyelitis (POM), which were seen at our institution (1985-2011). Data were extracted from a prospective protocol of bacteraemia cases recorded. Trends in main findings were considered in five periods. Major antibiotic resistance patterns were studied. A total of 601 cases of bacteraemic OAI, accounting for 1.8% of total bactaeremias, were studied: SA (48%), VOM (40%) and POM (17%). When comparing the 1985-91 and 2007-11 periods, the incidence of bacteraemic OAI increased from 2.34 to 5.78 episodes/100 000 inhabitants per year (p <0.001); and nosocomial and healthcare-related cases increased from 18% to 30% (p <0.001) and from 10% to 25% (p <0.001), respectively. Also, there was an increase of age (median, from 49 to 65 years, p <0.001), patients with comorbidities (23% to 59%, p <0.001), and device-related OAI (7% to 28%, p <0.001). Patterns of OAI were changing over time. Compared with younger patients, older adults (≥ 65 years) had more VOM, prosthetic-joint infections and enterococcal OAI. The percentage of OAI caused by methicillin-susceptible Staphylococcus aureus decreased, while those caused by methicillin-resistant S. aureus, streptococci, enterococci, and Gram-negative bacilli increased. There was a link between certain microorganisms with specific OAI and age of patients. Over the past three decades, bacteraemic OAI increased in association with aging and use of orthopaedic devices. Nosocomial and healthcare-related OAI increased, with a rise in multidrug-resistant bacteria. These trends should be considered when planning diagnostic and therapeutic guidelines for OAI.

Evolution and genetic diversity of the Spain23F-ST81 clone causing adult invasive pneumococcal disease in Barcelona (1990-2012).

OBJECTIVES: We aimed to analyse the clinical epidemiology and genetic diversity of invasive pneumococcal disease (IPD) episodes attributed to the Spain(23F)-ST81 (PMEN1) clone. METHODS: Fifty-eight (2.7%) of 2117 invasive pneumococci isolated from adult patients during the 1990-2012 period shared a PFGE pattern related to the PMEN1 clone. The genotype was confirmed by multilocus sequence typing. The pbp2x, pbp1a, pbp2b and pspA genes were PCR-amplified and sequenced. Polymorphisms in the pspC gene were identified by PCR restriction fragment length polymorphism. The presence of transposons with erythromycin and tetracycline resistance determinants was detected by PCR. RESULTS: The prevalence of the PMEN1 clone increased from 0.8% in 1991 to 6.2% in 2001, and decreased to 0% in 2010-12, concomitant with the introduction of the seven-valent pneumococcal conjugate vaccine for children. A total of 93.1% of patients had pneumonia, meningitis or peritonitis; 87.9% of patients had associated underlying diseases, mainly cancer, chronic obstructive pulmonary disease and diabetes. Two closely related sequence types (STs) (ST81, n = 52; ST85, n = 6) were detected, with different serotypes: 23F (n = 42), 19A (n = 9) and 19F (n = 6). All the isolates were resistant to penicillin, co-trimoxazole and chloramphenicol. All the isolates also shared the same pbp1a allele, whereas multiple alleles of pbp2b, pbp2x, pspA and pspC were detected. Of the isolates, 89.7% were tetracycline resistant and 60.3% (n = 35) were macrolide resistant, and resistance was associated with different Tn916-like transposons. CONCLUSIONS: Adult IPD caused by this clone was mainly detected in patients with underlying conditions, and genetic variability was observed among PMEN1 isolates collected in our area over the past 20 years.

Trends in mortality and antibiotic resistance among HIV-infected patients with invasive pneumococcal disease.

OBJECTIVES: The aim of the study was to describe trends and risk factors for mortality and changes in antibiotic resistance, serotypes and clones among HIV-infected patients with invasive pneumococcal disease (IPD). METHODS: A prospective study of 199 episodes of IPD occurring in a cohort of 4011 HIV-infected patients was carried out. Predictors of mortality included clinical and microbiological data. The 7-valent pneumococcal conjugate vaccine (PCV7) for children was introduced in late 2001. Time periods were classified for mortality studies as pre- (1986-1996), early (1997-2001) and late (2002-2007) highly active antiretroviral therapy (HAART) era, and for serotype studies as pre-PCV7 (1986-2001) and PCV7 (2002-2007) era. RESULTS: Of 199 IPD episodes, 71 (36%) occurred in HIV-infected patients with associated comorbidities (mainly liver cirrhosis; 52 of 71), which increased in recent years. The incidence of IPD decreased from the pre-HAART era to the early HAART era and then remained stable in the late HAART era (24.1, 8.4 and 7.4 episodes per 1000 patient-years, respectively). Rates of 30-day mortality have risen over the three periods (8, 19 and 25%, respectively; P = 0.017). In multiple logistic regression analysis, predictors of mortality were shock at presentation [odds ratio (OR) 7.01; 95% confidence interval (CI) 2.05-23.87] and associated comorbidities (OR 4.27; 95% CI 1.53-11.92). In the PCV7 era, IPD caused by non-PCV7 serotypes increased, and resistance to betalactams decreased. The most frequent genotypes were Spain(9V)-ST156, Spain(23F)-ST81, ST88(19F), Sweden(1)-ST304 and Spain(6B)-ST90. CONCLUSIONS: In the late HAART era, the incidence of IPD has not significantly decreased. Mortality from IPD has risen in association with an increase in comorbidities such as liver cirrhosis. New vaccination strategies are needed to diminish the burden of IPD in the HIV-infected population.

Timoma e inmunodeficiencia en un niño / Thymoma and immunodeficiency in an infant

Las inmunodeficiencias primarias más frecuentes son las humorales, en las que predominan las deficiencias de anticuerpos, y entre éstas las inmunodeficiencias con timoma son raras. En este trabajo se presenta un paciente masculino de 3 años de edad, sin antecedentes familiares de inmunodeficiencia, que a los 21 días de nacido presentó varicela afebril. A partir de un año de edad comenzó a presentar episodios frecuentes de infecciones de vías respiratorias altas (faringoamigdalitis, rinitis purulenta), y bajas como neumonías, o reacciones alérgicas a las picadas de insectos que se infectaban secundariamente. Los estudios inmunológicos revelaron una disminución de las concentraciones séricas de IgG, IgA, (IgG 7.4 g/l, IgA 0.52 g/l), IgM normal (IgM 1g/l) y niveles elevados de IgE (>200u/ml). El estudio radiológico mostró en el mediastino anterior una masa relacionada con el timo. El paciente recibió tratamiento con factor de transferencia, gammaglobulina y se realizó la timectomia por videotoracoscopía. El estudio histológico evidenció un timoma linfocítico benigno. Los linfocitos T CD2+, CD3+, CD8+ estaban disminuidos en el preoperatorio, mientras que en el post operatorio los linfocitos CD2+, CD4+ estaban disminuidos y los CD8+ aumentados

The most frequent primary immunodeficiency is the humoral, where the deficiency of antibodies prevails; among these, the immunodeficiency with thymoma is rare. In this work, a 3- yearold male is presented, without family antecedents of immunodeficiency, which 21 days after birth presented Chicken pox without fever. In the first year of age, he began to present frequent episodes of infections of the upper and the lower respiratory tract: tonsillitis, purulent rhinitis, and pneumonias. He also presented an allergic reaction to insect bites that became infected secondarily. The immunologic studies revealed a decrease of the seric concentrations of IgG, IgA (IgG 7.4 g/l, IgA 0.52 g/l), normal IgM values (IgM 1 g/l) and high levels of IgE (> 200u/ ml). The amount of CD2+, CD3+ and CD8+ T lymphocytes were diminished pre surgery. After surgery, the levels of CD2+, and CD4+ lymphocytes were diminished and those of CD8+ lymphocytes increased. The radiological study showed an anterior, mediastinal mass related to the thymus. The patient received treatment with transfer factor, gammaglobulin and underwent resection of the thymoma for videothoracoscopy. The histology study evidenced a benign lymphocytic thymoma

Educación sobre la prevención del dolor de espalda impartida a niños en las escuelas desde la Asistencia Primaria / Education in the prevention of backache imparted to school children by primary care workers

Objetivo: Estudio sobre consejos de higiene, con respecto a la postura y la prevención del dolor de espalda, impartidos a niños en el ámbito escolar desde la Asistencia Primaria. Metodología: Durante dos años, se efectuaron clases dirigidas a escolares del último curso de primer grado en las tres escuelas públicas pertenecientes al Área Básica de Salud. En estos escolares se realizó un estudio descriptivo de tipo observacional, seleccionando una muestra de 37 alumnos escogida aleatoriamente, según el método aleatorizado simple, que se llevó a cabo distribuyendo una encuesta previamente validada, que constaba de 7 ítems con preguntas sobre higiene postural, dolor de espalda y práctica de ejercicio físico. A 21 de estos alumnos se les distribuyó la encuesta antes de efectuar la clase de educación sanitaria, y a otros 16 se les distribuyó después de haber realizado la clase; posteriormente, se les pusieron tres ejemplos prácticos para ver sí los consejos impartidos se habían asimilado o no: recoger un objeto del suelo, coger un objeto puesto en lo alto de una estantería y sentarse en la mesa para escribir. Resultados: Estas clases se dirigieron a un total de 108 escolares que asistían al último curso de primer grado, en las tres escuelas públicas del Área Básica de Salud, durante los dos últimos años y también a los padres en el propio Centro de Salud, con muy buena aceptación por parte de todos, manifestando quedar satisfechos el 98 por ciento de los entrevistados. Por otra parte, al menos uno de cada dos niños manifestó haber tenido, al menos una vez en su vida, dolor de espalda. La distribución por sexos era del 51 por ciento de niños y del 49 por ciento de niñas. Respecto a los niños a los que se les distribuyó la encuesta antes de la clase, sólo el 1 por ciento consideraba que el dolor de espalda era debido a mala higiene de la postura, el 60 por ciento de ellos consideró que era mejor dormir en cama blanda, y sólo el 19 por ciento manifestó no efectuar habitualmente ejercicio físico. Todos los niños que contestaron la encuesta después de recibir la clase de educación sanitaria consideraban que el dolor de espalda era debido a una mala postura (excepto uno que lo atribuía también a enfermedad), el 63 por ciento estimo que era mejor dormir en cama dura y el 18 por ciento estimó que no hacían ejercicio regularmente. Después de la educación sanitaria, el 99 por ciento de ellos sabía que lo mejor para coger un objeto del suelo era hacerlo agachado en cuclillas, el 81 por ciento sabía que no podía estirar demasiado la espalda para coger un objeto que estuviera alto y que lo mejor era subirse a una banqueta, y el 99 por ciento había aprendido a sentarse correctamente en la mesa, con la espalda recostada en el respaldo de la silla. Conclusiones: La valoración de la educación sanitaria ha sido muy buena tanto por parte de los escolares, como de los padres y los profesores. Parece que, al menos a corto plazo, se asimilaron bien los cambios de conocimiento y actitud para prevenir el dolor de espalda. Se ha considerado, por tanto, que el dar consejos sobre higiene postural y práctica de ejercicio físico puede resultar una medida muy eficaz en la prevención del dolor de espalda (AU)

Clinical characteristics and response to newer quinolones in Legionella pneumonia: a report of 28 cases.

Twenty-eight (11.6%) out of 241 Spanish patients enrolled in an international phase III clinical trial of mild to moderate community-acquired pneumonia (CAP) comparing gemifloxacin vs. trovafloxacin were diagnosed of Legionnaires' disease. A definite diagnosis was established by seroconversion in 13 patients of whom only 2 had a positive Legionella urinary antigen. The remaining 15 patients were possible Legionella infections based on a single elevated IgG titer (> or = 1:512). All patients had a radiologically confirmed diagnosis of pneumonia, 5 (19%) patients were older than 65, comorbidity was present in 9 (33%), and 10 (36%) had to be hospitalized. Fifteen patients were treated with oral gemifloxacin (320 mg/day) and 13 with oral trovafloxacin (200 mg/day). Overall, clinical success occurred in 25 (89.3%) patients after 7 days of treatment and only 1 patient needed a 14-day treatment. There were only one adverse event withdrawal and one clinical failure, and no patients died. In light of the favorable clinical outcome, the use of newer fluoroquinolones seems adequate for the treatment of suspected or proven Legionella pneumonia.

Bacteremic pneumococcal cellulitis compared with bacteremic cellulitis caused by Staphylococcus aureus and Streptococcus pyogenes.

In order to better characterize bacteremic cellulitis caused by Streptococcus pneumoniae, a review was conducted of 10 cases of bacteremic pneumococcal cellulitis, which represented 0.9% of all cases of pneumococcal bacteremia (n=1,076) and 3.2% of all cases of community-acquired bacteremic cellulitis (n=312) that occurred in the Hospital de Bellvitge, Barcelona, from 1984 to 2001. In addition to these 10 cases, 28 cases of bacteremic pneumococcal cellulitis from the literature (Medline 1975-2001) were reviewed. Pneumococcal cellulitis of the face, neck, and trunk was observed more frequently in patients with systemic lupus erythematosus and hematologic disorders, while pneumococcal cellulitis of the limbs was more common in patients with diabetes, alcoholism, and parenteral drug use. In the Hospital de Bellvitge group, bacteremic cellulitis due to Streptococcus pneumoniae was more frequently associated with severe underlying diseases than that due to Staphylococcus aureus or Streptococcus pyogenes (100%, 57%, and 72%, respectively;P=0.01). A concomitant extracutaneous focus of infection (e.g., respiratory tract infection) suggesting hematogenous spread with metastatic cellulitis was more frequent in patients with pneumococcal cellulitis, while a local cutaneous entry of microorganisms was feasible in most patients with Staphylococcus aureus or Streptococcus pyogenes cellulitis. The 30-day mortality was 10% in patients with pneumococcal cellulitis, 13% in patients with Staphylococcus aureus cellulitis, and 23% in patients with Streptococcus pyogenes cellulitis (P=0.3). Thus, bacteremic pneumococcal cellulitis is an unusual manifestation of pneumococcal disease and occurs mainly in patients with severe underlying diseases. In most cases, pneumococcal cellulitis has a different pathophysiologic mechanism than cellulitis caused by Staphylococcus aureus or Streptococcus pyogenes.
