JOAQUÍN GÓMEZ GÓMEZ, JORGE-LUIS GÓMEZ TORRES, ALICIA HERNÁNDEZ TORRES, JOSÉ ANTONIO GARCÍA CÓRDOBA, MANUEL CANTERAS JORDANA

Objective. The aim of the study was to analyze the impact of steroid treatment in patients with community acquired pneumonia (CAP), both in length of stay and economical cost of admission at a clinical university hospital.
Patients and methods. Prospective study of admitted patients with the diagnosis of CAP, both in Internal Medicine and Infectious diseases department. The study was conducted from January to march 2015; patients receiving steroids from diagnosis to end of antibiotic treatment were classified as group I; otherwise, they were considered in group II. Administration of steroids was done according to the criteria of the responsible. Cost was stablished according to CAP Diagnostic Related Group (DRG).
Results. Prevalence of patients younger than 65 year-old was higher in group I (p<0.05). In bivariate analyses, mean admission time was lower in group I (5.37 vs 8.88 days) (p<0.0005) and also economical cost (2,361 euros vs 3,907 euros) (p<0.0005). In multivariate analysis, factors independently associated to higher cost (>3,520 euros) were COPD (OR=2.602; 95% CI 1.074-6.305) and group II (patients with no steroids) (OR=6.2; p=0,007).
Conclusions. No administration of steroids in patients with CAP was associated, together with COPD, with higher economical cost (evaluated by DRG/length of stay).

LUCÍA LÓPEZ-AMOR, LUCÍA VIÑA, LORENA MARTÍN, CLEMENTINA CALLEJA, RAQUEL RODRÍGUEZ-GARCÍA, IVÁN ASTOLA, LORENA FORCELLEDO, LAURA ÁLVAREZ-GARCÍA, CARMEN DÍAZ-GÓMEZ, JAVIER FERNÁNDEZ-DOMÍNGUEZ, FERNANDO VÁZQUEZ, DOLORES ESCUDERO, GRUPO DE INVESTIGACIÓN EN MICROBIOLOGÍA TRASLACIONAL DEL INSTITUTO DE INVESTIGACIÓN SANITARIA DEL PRINCIPADO DE ASTURIAS (ISPA)

Introduction.  Infectious complications related to external ventricular shunt (ICREVS) are a main problem in neurocritical intensive care units (ICU). The aim of the review is to assess the incidence of ICREVS and to analyse factors involved.
Material and methods.  Retrospective analysis, adult polyvalent ICU in a third level reference hospital. Patients carrying external ventricular shunt (DVE) were included. Those patients with central nervous system infection diagnosed prior DVE placement were excluded.
Results. 87 patients were included with 106 DVE. Most common admittance diagnosis was subarachnoid haemorrhage (49.4%). 31 patients with 32 DVE developed an ICREVS. Infection rate is 19.5 per 1000 days of shunt for ICREVS and 14 per 1000 days for ventriculitis. 31.6% of the patients developed ICREVS and 25.3% ventriculitis. Patients who developed ICREVS presented higher shunt manipulations (2.0 ± 0.6 vs. 3.26 ± 1.02, p=0.02), shunt repositioning (0.1 ± 0.1 vs. 0.2 ± 0.1) and ICU and hospital stay (29.8 ± 4.9 vs 49.8 ± 5.2, p<0.01 y 67.4 ± 18.8 vs. 108.9 ± 30.2, p=0.02. Those DVE with ICREVS were placed for longer not only at infection diagnosis but also at removal (12.6 ± 2.1 vs. 18.3 ± 3.6 and 12.6 ± 2.1 vs. 30.4 ± 7.3 days, p<0.01). No difference in mortality was found.
Conclusions. One out of three patients with a DVE develops an infection. The risk factors are the number of manipulations, repositioning and the permanency days. Patients with ICREVS had a longer ICU and hospital average stay without an increase in mortality.

MARÍA JOSÉ MUÑOZ-DÁVILA, JOSÉ MARÍA XANDRI GRAUPERA, GENOVEVA YAGÜE GUIRAO, CARME SALVADOR GARCÍA, MANUEL SEGOVIA HERNÁNDEZ

Introduction. Gastrostomy tube is the best option for long-term enteral nutrition. Among its limitations, infections represent the most frequent minor complication. Our aim is the knowledge of the number and type of gastrostomy tubes and its main indication in our hospital. In addition, prevalence of infectious complications was studied paying attention to the main etiologic agents and their antibiotic susceptibility.
Methods. Observational retrospective study from January 2010 to July 2015 through the electronic clinical history and the clinical microbiology laboratory software. Identification and antibiotic susceptibility of clinically significant isolates from patients with suspicion of gastrostomy tube infection have been analysed.
Results. Percutaneous endoscopic gastrostomy was performed in 203 patients (70.5%) and surgical gastrostomy in 85 (29.5%). The main reason identified for starting enteral nutrition through gastrostomy tube was malignant neoplasy, above all, lip, oral cavity and pharynx cancer (11.8%) and that from digestive organs (8.7%). Global prevalence of gastrostomy tube infection was 16.6%. The most common bacterial pathogens isolated wereStaphylococcus aureus (21.3%), Pseudomonas aeruginosa (13.1%), and Escherichia coli (9.8%). The percentage of multi resistant isolates was 3.1%.
Conclusions. Gastrostomy tube indications and type, and also, prevalence and microorganisms isolated from culture in infectious complications are similar to those described previously in the literature. The study allows the adaptation of the antibiotic prophylaxis and empirical antibiotic treatment thanks to the knowledge of the etiologic agents and their antibioticsusceptibility.

Importance of the forensic autopsy in the diagnosis of septic shock: a case report

AGUSTÍN SIBÓN-OLANO, ENCARNACIÓN SÁNCHEZ-RODRÍGUEZ, MÓNICA PAYÁ, ESTEFANÍA BARRERA-PÉREZ, MANUEL SALGUERO-VILLADIEGO, AMPARO FERNÁNDEZ-RODRÍGUEZ

Septic shock sometimes starts with unspecific symptoms that hamper the clinical diagnosis and, therefore an appropriate treatment. When the septic shock follows a fulminating course with a fatal outcome, the etiological diagnosis has to be conducted post-mortem. Sudden unexpected deaths in children and young adults are frequently the object of medico-legal autopsies. Some sudden unexpected deaths have an infectious origin, which requires further analyses, including microbiology, to establish the cause of death. Here, the case of a fatal septic shock in a 19-month old male infant is presented. After a mild foot injury, an infection by Streptococcus pyogenes progressed to septic shock with a fatal outcome as post-mortem studies demonstrated.

JUDITH ÁLVAREZ-OTERO, JOSE LUIS LAMAS-FERREIRO, LUCÍA GONZÁLEZ-GONZÁLEZ, IRENE RODRÍGUEZ-CONDE, MARÍA JOSÉ FERNÁNDEZ-SONEIRA, ALEXANDRA ARCA-BLANCO, JOSE RAMÓN BERMÚDEZ-SANJURJO, JAVIER DE LA FUENTE-AGUADO

Introduction. Pseudomonas aeruginosa is a non-fermentative gram-negative bacillus with a great ability to develop resistance to multiple antibiotics, including carbapenems, which is a growing problem worldwide. The aim of this study was to analyse the prevalence of carbapenem-resistant P. aeruginosa (CRPA) in urine cultures and to determine the risk factors associated with the development of carbapanem resistance.
Material and method. Positive urine cultures to P. aeruginosa between September 2012 and September 2014 were identified. We excluded repetitive cultures from the same patient. We created a database with different variables, including antimicrobial resistance. The prevalence of carbapenem resistance and the risk factors for growth of CRPA were analysed.
Results. Ninety-one patients with positive urine cultures to P. aeruginosa were included. The prevalence of CRPA was 22%. The risk factors to CRPA infection in the univariate analysis were: congestive heart failure (p=0.02), previous treatment with ampicillin (p=0.04), meropenem (p=0.04), piperacillin-tazobactam (p=0.01), trimethoprim-sulfamethoxazole (p= 0.01) and previous treatment with more than one antibiotic (p<0.01). Only congestive heart failure (p<0.01) and previous treatment with more than one antibiotic (p<0.01) showed statistically significant differences in the multivariate analysis.
Conclusions. The prevalence of CRPA in urine cultures is high in our population. We should assess the presence of risk factors as previous treatment with more than one antibiotic or comorbidities such as heart failure, in order to select an appropriate empirical treatment in patients with severe urinary tract infections.

Introduction. The human papillomavirus (HPV), is necessary to cause a woman developing cervical cancer. The aim of the study was to estimate the prevalence of women with HPV infection, covered by the program of prevention and early detection of cervical cancer of Castile and León (Spain).
Material and methods. Samples of women included in the screening program were analyzed. Including a total of 120,326 cervical swab samples, collected in the period from January 2012 to December 2014.
Results. 12,183 HPV positive samples were detected, representing a prevalence of 9.6 ‰, (IC 95% 9.5%-9.8%) in the female population. High-risk HPV were found in higher proportion that HPV low-risk genotypes. HPV prevalence correlates inversely with women age. Coinfections of multiple genotypes were found in one third of screened women population.
Conclusions. Data showed in this study are the first and wider Spanish results from a cervical cancer screening program population non opportunistic based on HPV detection. These results would serve as a reference for future prevalence studies and to evaluate the future impact of HPV vaccination campaigns.

Burden of influenza virus type B and mismatch with the flu vaccine in Spain                                 
 


JOSE Mª EIROS-BOUZA, ALBERTO PÉREZ-RUBIO              

 

Introduction. Since the 80s two lineages of type B viruses are co – circulating in the world. Antigenic differences between them are important and it leads to lack of cross-reactivity. The impact on the burden of disease due to influenza B virus, poor foresight in estimating which of the two lineages of B viruses circulate in the season, and the consequent lack of immunity in case of including the wrong strain make that the availability of the quadrivalent vaccine is very useful. The aim of this paper is to analyze the past influenza seasons in Spain to assess the burden of disease, divergence between the vaccine strain and the circulating B and viral characteristics associated with type B in each seasonal epidemic.
Material and methods. Review of all reports issued by the Influenza Surveillance System in Spain since the 2003-2004 season to 2012-2013.
Results. Over the past influenza seasons, although type A was present mostly, circulation of influenza B virus in each season was observed, even being co – dominant in some of them. In a high number of seasons the divergence between the vaccine strain and the circulating strain lineage has been observed
Conclusions. The protective effect of influenza vaccine has varied depending on the type / subtype of influenza virus studied. The vaccine effectiveness against influenza infection by influenza B virus has varied greatly depending on the season analyzed.

Safety of influenza vaccines in risk groups: analysis of adverse events following immunization reported in Valencian Community from 2005 to 2011                                 
 

ANA MARÍA ALGUACIL-RAMOS, TERESA Mª GARRIGUES-PELUFO, JULIO MUELAS-TIRADO, ANTONIO PORTERO-ALONSO, JORDI PEREZ-PANADÉS, JAIME FONS-MARTÍNEZ              

Objective. To evaluate reports of adverse events following influenza immunization by sex, risk and age groups in Valencian Community from 2005 to 2011.
Methods. A pharmacoepidemiological descriptive cross-sectional observational study based on the reports of adverse events following immunization (AEFI) against influenza, registered through the Vaccination Information System (SIV) of Valencian Community from 1 January 2005 until 31 December 2011 was done.
Results. During the study period 5,107,790 doses of vaccine against influenza were reported, with an AEFI incidence of 1.94 per 100,000 (95% CI 1.59 to 2.36), and 228,094 doses of vaccine for influenza A (H1N1) pdm09 (96.45 per 100,000, 95%CI 84.52-110.06). The 70.71% (70) and 64.55% (142), respectively, of AEFI were in women. The healthcare workers group had a higher reporting rate for seasonal influenza (25.35 per 100,000; 95%CI: 17.65-36.40) and for influenza A(H1N1) pdm09 (864.13 per 100,000; 95%CI 714.38-1044.93) during the study period.
Conclusions. Vaccines against influenza administered during the study had a high safety profile in both populations with disease risk and other susceptible target groups of vaccination. Adverse reactions reported during the study mostly coincide with those described in the summary of product characteristics of vaccines.

 MARÍA JOSÉ DEVESA, FRANCISCA CUENCA, SONIA IZQUIERDO, PILAR SÁNCHEZ-POBRE, JOSÉ MARÍA LADERO, GUSTAVO LÓPEZ-ALONSO, MANUEL DÍAZ-RUBIO, ENRIQUE REY              

Hepatitis C virus infection is a major health burden affecting 130-170 million people worldwide. Approximately 10-30% of those with chronic hepatitis C will progress to cirrhosis over 20-30 years. The development of new direct-acting antivirals has changed the management of the disease, allowing efficacious Interferon-free therapies superior to prior treatment regimens with minimal side effects, even in some subgroups previously thought to be difficult to cure such as cirrhotic patients.

Measurement of antimicrobial consumption using DDD per 100 bed-days versus DDD per 100 discharges after the implementation of an antimicrobial stewardship program     

                        
ROBERTO COLLADO, JUAN EMILIO LOSA, ELENA ALBA, ÁLVARO PIEDAD TORO, LEONOR MORENO, MONTSERRAT PÉREZ              

Introduction.  Monitoring antimicrobial consumption in hospitals is a necessary measure. The indicators commonly employed do not clearly reflect the antibiotic selection pressure. The objective of this study is to evaluate two different methods that analyze antimicrobial consumption based on DDD, per stay and per discharge, before and after the implementation an antimicrobial stewardship program.
Material and methods. Comparative pre-post study of antimicrobial consumption  with the implementation of an antimicrobial stewardship program using DDD per 100 bed-days and DDD per 100 discharges as indicators.
Results. Hospital bed days remained stable and discharges increased slightly along the period of study Antibiotic consumption in DDD per 100 bed-days decreased by 2.5% versus 3.8% when expressed as DDD per 100 discharges. Antifungal consumption decreased by more than 50%.
Conclusions. When average hospital stay decreases, reductions in the consumption of antimicrobials with an antimicrobial stewardship program system occur at the expense of reducing the number of patients receiving treatment, while increases occur due to longer durations of treatment.
