Abstract

Objectives

To characterize the antimicrobial susceptibility, molecular epidemiology and carbapenem resistance mechanisms in Pseudomonas aeruginosa isolates recovered from respiratory tract samples from patients with ventilator-associated pneumonia enrolled in the MagicBullet clinical trial.

Methods

Isolates were collected from 53 patients from 12 hospitals in Spain, Italy and Greece. Susceptibility was determined using broth microdilution and Etest. MALDI-TOF MS was used to detect carbapenemase activity and carbapenemases were identified by PCR and sequencing. Molecular epidemiology was investigated using PFGE and MLST.

Results

Of the 53 isolates, 2 (3.8%) were considered pandrug resistant (PDR), 19 (35.8%) were XDR and 16 (30.2%) were MDR. Most (88.9%) of the isolates from Greece were MDR, XDR or PDR, whereas fewer of the isolates from Spain (33.3%) and Italy (43.5%) showed antibiotic resistance. Three Greek isolates were resistant to colistin. Overall, the rates of resistance of P. aeruginosa isolates to imipenem, ciprofloxacin, ceftolozane/tazobactam and ceftazidime/avibactam were 64.1%, 54.7%, 22.6% and 24.5%, respectively. All isolates resistant to ceftolozane/tazobactam and ceftazidime/avibactam (Greece, n = 10; and Italy, n = 2) carried blaVIM-2. Spanish isolates were susceptible to the new drug combinations. Forty-eight restriction patterns and 27 STs were documented. Sixty percent of isolates belonged to six STs, including the high-risk clones ST-111, ST-175 and ST-235.

Conclusions

MDR/XDR isolates were highly prevalent, particularly in Greece. The most effective antibiotic against P. aeruginosa was colistin, followed by ceftolozane/tazobactam and ceftazidime/avibactam. blaVIM-2 is associated with resistance to ceftolozane/tazobactam and ceftazidime/avibactam, and related to highly resistant phenotypes. ST-111 was the most frequent and disseminated clone and the clonal diversity was lower in XDR and PDR strains.

Abstract

During 2007-2009 and 2012-2014, avian influenza virus (AIV) was studied in a wild avian community of a northern Spanish wetland using non-invasive sampling methods and host identification by COI barcoding. The aim of this longitudinal study was to evaluate AIV dynamics in a natural wetland ecosystem, taking into account both virological aspects and ecological traits of hosts. Global AIV prevalence decreased significantly during the second sampling period (0.3%) compared to the first (6.6%). Circulating subtype distributions were also different between periods, with a noteworthy H5 and H7 subtype richness during the first sampling period. Mallard Anas platyrhynchos was identified as the main AIV host, although not all positive samples could be ascribed to the host. We modelled AIV prevalence with regard to the avian host community composition and meteorological data from the wetland. Statistical analysis revealed seasonal differences in AIV detection, with higher prevalence during the breeding season compared to other phenological events. The model also shows that the lower AIV prevalence during the second study period was associated with a significant reduction of breeding Anseriformes in the wetland, revealing a long-term fluctuation of AIV prevalence driven by the breeding Anseriformes community. This longitudinal study on AIV epidemiology in a natural ecosystem reveals that although prevalence follows seasonal and annual patterns, long-term prevalence fluctuation is linked to the breeding community composition and size. These results are relevant to understanding the influence of host ecology on pathogen transmission for preventing and managing influenza emergence.

Abstract

Seasonal influenza is a cause of hospitalization, especially in people with underlying disease or extreme age, and its severity may differ depending on the types and subtypes of circulating viruses. We investigated the factors associated with ICU admission or death in hospitalized patients with severe laboratory-confirmed influenza according to the viral type and subtype. An observational epidemiological study was carried out in patients aged ≥18 years from 12 Catalan hospitals between 2010 and 2016. For each reported case we collected demographic, virological and clinical characteristics. A mixed-effects logistic regression model was used to estimate crude and adjusted ORs. 1726 hospitalized patients were included: 595 (34.5%) were admitted to the ICU and 224 (13.0%) died. Lower ICU admission was associated with age ≥75 years in all influenza types and subtypes and with age 65–74 years for type A. In contrast, the 65–74 and ≥75 years age groups were associated with an increased risk of death in all types and subtypes, especially for type B (aOR 27.42, 95% CI: 4.95–151.93 and 15.96; 95% CI: 3.01–84.68). The comorbidity most closely associated with severe outcomes was immune deficiency, which was associated with death for type B (aOR 9.02, 95% CI: 3.05–26.69) and subtype A(H1N1)pdm09 (aOR 3.16, 95% CI: 1.77–5.66). Older age was a differential factor for ICU admission and death: it was associated with lower ICU admission but a risk factor for death. The comorbidity with the closest association with death was immune deficiency, mainly in influenza type B patients.

Abstract

We conducted an observational study from January 2016 through January 2017 of patients admitted to a reference pediatric hospital in Madrid, Spain, for neurologic symptoms and enterovirus infection. Among the 30 patients, the most common signs and symptoms were fever, lethargy, myoclonic jerks, and ataxia. Real-time PCR detected enterovirus in the cerebrospinal fluid of 8 patients, nasopharyngeal aspirate in 17, and anal swab samples of 5. The enterovirus was genotyped for 25 of 30 patients; enterovirus A71 was the most common serotype (21/25) and the only serotype detected in patients with brainstem encephalitis or encephalomyelitis. Treatment was intravenous immunoglobulins for 21 patients and corticosteroids for 17. Admission to the pediatric intensive care unit was required for 14 patients. All patients survived. At admission, among patients with the most severe disease, leukocytes were elevated. For children with brainstem encephalitis or encephalomyelitis, clinicians should look for enterovirus and not limit testing to cerebrospinal fluid.

Highlights

  • The study reports virological and clinical enterovirus surveillance in Catalonia.
  • The four enterovirus species cocirculated, distinguishing up to 27 different types.
  • Most of neurological studied cases were from the 2016 spring outbreak.
  • EV-A71 was one of the most detected EV, mostly during the outbreak.
  • Rhombencephalitis cases were related to EV-A71 infection.
  • EV-D68 was associated with lower respiratory tract infections.
  • Necessity to perform EV surveillance in primary care settings.

 

Abstract

Background

Enterovirus (EV) infections are usually asymptomatic or mild, but symptomatic infections can evolve to severe complications. Outbreaks of EV-A71 and EV-D68 have been recently reported worldwide, sometimes related to severe clinical outcomes.

Objective

To describe EV genetic diversity and the clinical outcomes from paediatric patients attended at a tertiary university hospital in Barcelona (Catalonia, Spain) from 2014 to 2017.

Study design

Specimens were collected from paediatric (<17 years old) cases with suspicion of respiratory tract infection or EV infection. EV laboratory-confirmation was performed by specific real-time multiplex RT-PCR assay. Partial viral VP1 protein was sequenced for genetic characterisation by phylogenetic analyses.

Results

A total of 376 (7%) from 5,703 cases were EV laboratory-confirmed. Phylogenetic analyses of VP1 (210; 81%) sequences distinguished up to 27 different EV types distributed within EV-A (82; 40%), EV-B (90; 42%), EV-C (5; 2%), and EV-D (33; 15%), in addition to 50 (19%) rhinoviruses. The most predominant were EV-A71 (37; 45%) and EV-D68 (32; 99%). EV-A71 was highly related to neurological complications (25/39, 63%), of which 20/39 were rhombencephalitis, and most EV-D68 (28/32, 88%) were associated with lower respiratory tract infections (LRTI), and exceptionally one (3%) with flaccid paralysis.

Conclusions

EV-A71 and EV-D68 were the most detected EV in respiratory specimens. EV-A71 was highly related to neurological disease and EV-D68 was often associated with LRTI. However, both potential relatedness to neurological diseases makes the monitoring of EV circulation obligatory.

Highlights

  • In this first Spanish molecular epidemiological study, encephalitis was more frequent in patients infected with VZV clades within genogroup E, suggesting earlier introduction of these clades.
  • First evidence of recombination in Spain: VZV clade 1 and clade 3 recombinants were found in six cases.
  • VZV clade 2 vaccine strains were found in three patients with herpes zoster and one with neurological disease (encephalitis and retinitis).

 

Abstract

Background

Despite childhood universal VZV immunization was introduced in 2015, there are no data on VZV clade distribution in Spain.

Objectives

To characterize the varicella-zoster virus strains circulating in Spain between 1997 and 2016.

Study Design

In this retrospective study, we determined the VZV clades in 294 patients with different pathologies (mainly encephalitis, zoster and varicella) by sequencing three fragments within ORF 22, ORF 21 and ORF 50 and, subsequently analyzing 7 relevant SNPs.

Results

Among these 294 patients, 132(44.9%) patients were infected by clade 1, 42(14.3%) patients by clade 3, 19(6.5%) by clade 5, 29(9.9%) by clade VI and 3(1%) by clade 4. Four patients (1.4%) were infected by clade 2 vOKA strains, who received one dose of live-attenuated varicella vaccine. Putative recombinant clade 1/3 was identified in 6 cases (2.0%). Results obtained from partial sequences were assigned to clade 1 or 3 in 56(19%) patients and clade 5 or VI in 3(1.0%) patients. In the multivariate analysis, encephalitis was independently associated with clades 1 and 3 and age >14y.o. (P = 0.035 and P = 0.021, respectively). Additionally, Madrid had significant fewer cases of encephalitis compared with the rest of regions analyzed (P = 0.001).

Conclusions

Higher prevalence of clades 1 and 3 and their relation with encephalitis and age >14y.o. suggest earlier introduction of this clades in Spain. Putative interclade 1 and 3 recombinants are circulating in patients with encephalitis, herpes zoster and varicella. Several cases were related to vOKA vaccination but vaccine strains do not seem to circulate in the general population.

Abstract

Introduction

When influenza vaccination is ineffective in preventing influenza virus infection, it may still reduce the severity of influenza-associated disease. Here, we estimate the effect of influenza vaccination in preventing severe outcomes e.g. intensive care unit (ICU) admission and death, even though it did not prevent influenza virus infection and subsequent hospitalisation.

Methods

An observational case–case epidemiological study was carried out in 12 sentinel hospitals in Catalonia (Spain) over six influenza seasons 2010/11–2015/16. Cases were individuals with severe laboratory-confirmed influenza virus infection and aged 18 years and older. For each reported case we collected demographic, virological and clinical characteristics. Logistic regression was used to estimate the crude, adjusted odd ratios (aOR) and 95% confidence intervals (CI).

Results

Of 1,727 hospitalised patients included in the study, 799 were female (46.7%), 591 (34.2%) were admitted to the ICU and 223 (12.9%) died. Influenza vaccination uptake was lower in cases that required ICU admission or died (21.2% vs 29.7%, p < 0.001). The adjusted influenza vaccination effectiveness in preventing ICU admission or death was 23% (95% CI: 1 to 40). In an analysis restricted to sex, age group and antiviral treatment, influenza vaccination had a positive effect on disease severity in all age groups and categories.

Conclusions

We found that influenza vaccination reduced the severity of disease even in cases where it did not prevent infection and influenza-associated hospitalisation. Therefore, increased vaccination uptake may reduce complications, ICU admission and death.
