Abstract

Introduction: 18F-FDG-PET/CT is recommended to improve the diagnosis of prosthetic valve infective endocarditis (PVIE) and is a major criterion in the ESC-2015 classification. However, there is little evidence for its usefulness in the follow-up of medically treated PVIE patients. Methods: A monocentric retrospective analysis of patients hospitalized for PVIE between January 2013 and December 2019 who were not treated with surgery and who had at least two 18F-FDG-PET/CT examinations during their medical management. Results: Among 170 patients with PVIE, 117 were treated with antibiotic therapy but no surgery. Of these, 36 (31%) had at least two 18F-FDG-PET/CT examinations. At initial imaging, 28 patients had heterogeneous FDG uptake on their prosthetic valve and eight on their associated aortic graft. Hypermetabolism of spleen and bone marrow (HSBM) was observed in 18 and 19 patients, respectively. At the first follow-up 18F-FDG-PET/CT, 21 (58%) patients still had heterogeneous uptake, indicating persistent active endocarditis. HSBM was still present at the last follow-up imaging in four of the six patients with recurrent PVIE. Conclusion: 18F-FDG-PET/CT monitoring of medically treated patients with PVIE provides valuable additional information and prospective multicentric study should be conducted to assess its usefulness.

Abstract

International audience; Objective: The 23 French Regional Pneumococcal Observatories (ORPs) analyzed antibiotic resistance and serotypes of Streptococcus pneumoniae strains isolated from invasive infections in France over a 12-year period.Methods: Between 2009 and 2021, the ORPs analyzed 19,319 strains, including 1,965 in children and 17,354 in adults. Strains were assessed for their resistance to penicillin G, amoxicillin and cefotaxime. Serotypes were identified in collaboration with the National Reference Centre.Results: During this period, the number of strains collected yearly decreased significantly. The decrease was particularly pronounced up until 2013, especially in children (-61.0%). However, penicillin non-susceptible strains (PNSPs) increased in children (24.7% in 2009 vs 45.0% in 2021, p < 0.0001) and in adults (27.1% in 2009 vs 31.3% in 2021, p < 0.05), as well as resistance (I + R) to amoxicillin (children: 12.5% in 2009 vs 19.4% in 2021, p < 0.05; adults: 13.4% in 2009 vs 14.5% in 2021, NS) and resistance (I + R) to cefotaxime (children: 8.0% in 2009 vs 13.1% in 2021, p < 0.05; adults: 7.1% in 2009 vs 11.9% in 2021, p < 0.0001). All in all, the proportion of strains belonging to serotypes present in the PCV13 vaccine has fallen sharply, from 64.8% in 2009 to 23.6 % in 2021. At the same time, serotypes such as 8, 10A, 11A, 15B/C and 9N, not included in PCV13, were increasing.Conclusion: During the study period, data collected by the network highlighted an increase of invasive PNSPs in children and non-vaccine serotypes. Surveillance of resistance and serotypes remains instrumental, particularly to monitor the evolution of vaccine efficacy.

Abstract

Whether cefazolin is as effective and safer than antistaphylococcal penicillins (ASPs) for the treatment of methicillin-susceptible Staphylococcus aureus (MSSA) infective endocarditis (IE) is still debated in the absence of a randomized controlled trial. In this quasi-experimental study, we aimed to assess the effectiveness and safety of these two treatments in MSSA-IE, using the ASPs nationwide shortage in April 2016 as a unique opportunity to overcome the indication bias associated with observational studies. In this single-centre study, we compared patients with Duke-Li definite MSSA-IE treated with ASPs from January 2015 to March 2016 versus those treated with cefazolin from April 2016 to December 2018, when ASPs were not available. Effectiveness outcome was 90-day all-cause mortality. Safety outcomes included significant decrease in GFR and significant increase in serum liver enzymes. Logrank test was used to compare survival rates. Of 73 patients with MSSA-IE, 35 and 38 were treated with ASPs and cefazolin, respectively. Baseline patients' characteristics (demography, native or prosthetic valve IE, clinical characteristics, cardiac and septic complications) were similar between groups. Ninety-day all-cause mortality was 28.6% and 21.1%, in patients treated with ASPs and cefazolin, respectively (logrank p = 0.5727). There was no difference between groups for incident renal or liver toxicity events: acute kidney injury 45.7% vs. 44.7% (p = 0.933), increased ALT 5.7% vs. 13.2% (p = 0.432), bilirubin increase 5.7% vs. 10.5% (p = 0.676), in ASPs vs. cefazolin groups, respectively. In this quasi-experimental, effectiveness and safety did not statistically differ between ASPs and cefazolin for MSSA-IE treatment. [ABSTRACT FROM AUTHOR]

Abstract

Background-Host factors and complications have been associated with higher mortality in infective endocarditis (IE). We sought to develop and validate a model of clinical characteristics to predict 6-month mortality in IE. Methods and Results-Using a large multinational prospective registry of definite IE (International Collaboration on Endocarditis [ICE]-Prospective Cohort Study [PCS], 2000-2006, n=4049), a model to predict 6-month survival was developed by Cox proportional hazards modeling with inverse probability weighting for surgery treatment and was internally validated by the bootstrapping method. This model was externally validated in an independent prospective registry (ICE-PLUS, 2008-2012, n=1197). The 6-month mortality was 971 of 4049 (24.0%) in the ICE-PCS cohort and 342 of 1197 (28.6%) in the ICE-PLUS cohort. Surgery during the index hospitalization was performed in 48.1% and 54.0% of the cohorts, respectively. In the derivation model, variables related to host factors (age, dialysis), IE characteristics (prosthetic or nosocomial IE, causative organism, left-sided valve vegetation), and IE complications (severe heart failure, stroke, paravalvular complication, and persistent bacteremia) were independently associated with 6-month mortality, and surgery was associated with a lower risk of mortality (Harrell's C statistic 0.715). In the validation model, these variables had similar hazard ratios (Harrell's C statistic 0.682), with a similar, independent benefit of surgery (hazard ratio 0.74, 95% CI 0.62-0.89). A simplified risk model was developed by weight adjustment of these variables. Conclusions-Six-month mortality after IE is 25% and is predicted by host factors, IE characteristics, and IE complications. Surgery during the index hospitalization is associated with lower mortality but is performed less frequently in the highest risk patients. A simplified risk model may be used to identify specific risk subgroups in IE.

Abstract

Background. The impact of early valve surgery (EVS) on the outcome of Staphylococcus aureus (SA) prosthetic valve infective endocarditis (PVIE) is unresolved. The objective of this study was to evaluate the association between EVS, performed within the first 60 days of hospitalization, and outcome of SA PVIE within the International Collaboration on Endocarditis-Prospective Cohort Study. Methods. Participants were enrolled between June 2000 and December 2006. Cox proportional hazards modeling that included surgery as a time-dependent covariate and propensity adjustment for likelihood to receive cardiac surgery was used to evaluate the impact of EVS and 1-year all-cause mortality on patients with definite left-sided S. aureus PVIE and no history of injection drug use. Results. EVS was performed in 74 of the 168 (44.3%) patients. One-year mortality was significantly higher among patients with S. aureus PVIE than in patients with non-S. aureus PVIE (48.2% vs 32.9%; P = .003). Staphylococcus aureus PVIE patients who underwent EVS had a significantly lower 1-year mortality rate (33.8% vs 59.1%; P = .001). In multivariate, propensity-adjusted models, EVS was not associated with 1-year mortality (risk ratio, 0.67 [95% confidence interval, .39-1.15]; P = .15). Conclusions. In this prospective, multinational cohort of patients with S. aureus PVIE, EVS was not associated with reduced 1-year mortality. The decision to pursue EVS should be individualized for each patient, based upon infection-specific characteristics rather than solely upon the microbiology of the infection causing PVIE.Copyright © The Author 2014.

Abstract

Candida infective endocarditis is a rare disease with a high mortality rate. Our understanding of this infection is derived from case series, case reports, and small prospective cohorts. The purpose of this study was to evaluate the clinical features and use of different antifungal treatment regimens for Candida infective endocarditis. This prospective cohort study was based on 70 cases of Candida infective endocarditis from the International Collaboration on Endocarditis (ICE)-Prospective Cohort Study and ICE-Plus databases collected between 2000 and 2010. The majority of infections were acquired nosocomially (67%). Congestive heart failure (24%), prosthetic heart valve (46%), and previous infective endocarditis (26%) were common comorbidities. Overall mortality was high, with 36% mortality in the hospital and 59% at 1 year. On univariate analysis, older age, heart failure at baseline, persistent candidemia, nosocomial acquisition, heart failure as a complication, and intracardiac abscess were associated with higher mortality. Mortality was not affected by use of surgical therapy or choice of antifungal agent. A subgroup analysis was performed on 33 patients for whom specific antifungal therapy information was available. In this subgroup, 11 patients received amphotericin B-based therapy and 14 received echinocandin-based therapy. Despite a higher percentage of older patients and nosocomial infection in the echinocandin group, mortality rates were similar between the two groups. In conclusion, Candida infective endocarditis is associated with a high mortality rate that was not impacted by choice of antifungal therapy or by adjunctive surgical intervention. Additionally, echinocandin therapy was as effective as amphotericin B-based therapy in the small subgroup analysis.Copyright © 2015, American Society for Microbiology.

Abstract

Methods and results Among 5591 patients included in the International Collaboration on Endocarditis Prospective Cohort Study, 1467 patients with definite IE were operated on during the active phase and had a biological (37%) or mechanical (63%) valve replacement. Patients who received bioprostheses were older (62 vs 54 years), more often had a history of cancer (9% vs 6%), and had moderate or severe renal disease (9% vs 4%); proportion of health care-associated IE was higher (26% vs 17%); intracardiac abscesses were more frequent (30% vs 23%). In-hospital and 1-year death rates were higher in the bioprosthesis group, 20.5% vs 14.0% (p = 0.0009) and 25.3% vs 16.6% (p <.0001), respectively. In multivariable analysis, mechanical prostheses were less commonly implanted in older patients (odds ratio: 0.64 for every 10 years), and in patients with a history of cancer (0.72), but were more commonly implanted in mitral position (1.60). Bioprosthesis was independently associated with 1-year mortality (hazard ratio: 1.298). Conclusions Patients with IE who receive a biological valve replacement have significant differences in clinical characteristics compared to patients who receive a mechanical prosthesis. Biological valve replacement is independently associated with a higher in-hospital and 1-year mortality, a result which is possibly related to patient characteristics rather than valve dysfunction. Background Nearly half of patients require cardiac surgery during the acute phase of infective endocarditis (IE). We describe the characteristics of patients according to the type of valve replacement (mechanical or biological), and examine whether the type of prosthesis was associated with in-hospital and 1-year mortality.Copyright © 2014 Elsevier Ireland Ltd.

Abstract

The HACEK organisms (Haemophilus species, Aggregatibacter species, Cardiobacterium hominis, Eikenella corrodens, and Kingella species) are rare causes of infective endocarditis (IE). The objective of this study is to describe the clinical characteristics and outcomes of patients with HACEK endocarditis (HE) in a large multi-national cohort. Patients hospitalized with definite or possible infective endocarditis by the International Collaboration on Endocarditis Prospective Cohort Study in 64 hospitals from 28 countries were included and characteristics of HE patients compared with IE due to other pathogens. Of 5591 patients enrolled, 77 (1.4%) had HE. HE was associated with a younger age (47 vs. 61 years; p<0.001), a higher prevalence of immunologic/vascular manifestations (32% vs. 20%; p<0.008) and stroke (25% vs. 17% p = 0.05) but a lower prevalence of congestive heart failure (15% vs. 30%; p = 0.004), death in-hospital (4% vs. 18%; p = 0.001) or after 1 year follow-up (6% vs. 20%; p = 0.01) than IE due to other pathogens (n = 5514). On multivariable analysis, stroke was associated with mitral valve vegetations (OR 3.60; CI 1.34-9.65; p<0.01) and younger age (OR 0.62; CI 0.49-0.90; p<0.01). The overall outcome of HE was excellent with the in-hospital mortality (4%) significantly better than for non-HE (18%; p<0.001). Prosthetic valve endocarditis was more common in HE (35%) than non-HE (24%). The outcome of prosthetic valve and native valve HE was excellent whether treated medically or with surgery. Current treatment is very successful for the management of both native valve prosthetic valve HE but further studies are needed to determine why HE has a predilection for younger people and to cause stroke. The small number of patients and observational design limit inferences on treatment strategies. Self selection of study sites limits epidemiological inferences. © 2013 Chambers et al.

Abstract

Background. The timing of cardiac surgery after stroke in infective endocarditis (IE) remains controversial. We examined the relationship between the timing of surgery after stroke and the incidence of in-hospital and 1-year mortalities. Methods. Data were obtained from the International Collaboration on Endocarditis-Prospective Cohort Study of 4794 patients with definite IE who were admitted to 64 centers from June 2000 through December 2006. Multivariate logistic regression and Cox regression analyses were performed to estimate the impact of early surgery on hospital and 1-year mortality after adjustments for other significant covariates. Results. Of the 857 patients with IE complicated by ischemic stroke syndromes, 198 who underwent valve replacement surgery poststroke were available for analysis. Overall, 58 (29.3%) patients underwent early surgical treatment vs 140 (70.7%) patients who underwent late surgical treatment. After adjustment for other risk factors, early surgery was not significantly associated with increased in-hospital mortality rates (odds ratio, 2.308; 95% confidence interval[CI], .942-5.652). Overall, probability of death after 1-year follow-up did not differ between 2 treatment groups (27.1% in early surgery and 19.2% in late surgery group, P = .328; adjusted hazard ratio, 1.138; 95% CI, .802-1.650). Conclusions. There is no apparent survival benefit in delaying surgery when indicated in IE patients after ischemic stroke. Further observational analyses that include detailed pre- and postoperative clinical neurologic findings and advanced imaging data (eg, ischemic stroke size), may allow for more refined recommendations on the optimal timing of valvular surgery in patients with IE and recent stroke syndromes.Copyright © The Author 2012.

Abstract

The HACEK organisms (Haemophilus species, Aggregatibacter species, Cardiobacterium hominis, Eikenella corrodens, and Kingella species) are rare causes of infective endocarditis (IE). The objective of this study is to describe the clinical characteristics and outcomes of patients with HACEK endocarditis (HE) in a large multi-national cohort. Patients hospitalized with definite or possible infective endocarditis by the International Collaboration on Endocarditis Prospective Cohort Study in 64 hospitals from 28 countries were included and characteristics of HE patients compared with IE due to other pathogens. Of 5591 patients enrolled, 77 (1.4%) had HE. HE was associated with a younger age (47 vs. 61 years; p<0.001), a higher prevalence of immunologic/vascular manifestations (32% vs. 20%; p<0.008) and stroke (25% vs. 17% p = 0.05) but a lower prevalence of congestive heart failure (15% vs. 30%; p = 0.004), death in-hospital (4% vs. 18%; p = 0.001) or after 1 year follow-up (6% vs. 20%; p = 0.01) than IE due to other pathogens (n = 5514). On multivariable analysis, stroke was associated with mitral valve vegetations (OR 3.60; CI 1.34-9.65; p<0.01) and younger age (OR 0.62; CI 0.49-0.90; p<0.01). The overall outcome of HE was excellent with the in-hospital mortality (4%) significantly better than for non-HE (18%; p<0.001). Prosthetic valve endocarditis was more common in HE (35%) than non-HE (24%). The outcome of prosthetic valve and native valve HE was excellent whether treated medically or with surgery. Current treatment is very successful for the management of both native valve prosthetic valve HE but further studies are needed to determine why HE has a predilection for younger people and to cause stroke. The small number of patients and observational design limit inferences on treatment strategies. Self selection of study sites limits epidemiological inferences. © 2013 Chambers et al.

Abstract

The HACEK organisms (Haemophilus species, Aggregatibacter species, Cardiobacterium hominis, Eikenella corrodens, and Kingella species) are rare causes of infective endocarditis (IE). The objective of this study is to describe the clinical characteristics and outcomes of patients with HACEK endocarditis (HE) in a large multi-national cohort. Patients hospitalized with definite or possible infective endocarditis by the International Collaboration on Endocarditis Prospective Cohort Study in 64 hospitals from 28 countries were included and characteristics of HE patients compared with IE due to other pathogens. Of 5591 patients enrolled, 77 (1.4%) had HE. HE was associated with a younger age (47 vs. 61 years; p<0.001), a higher prevalence of immunologic/vascular manifestations (32% vs. 20%; p<0.008) and stroke (25% vs. 17% p = 0.05) but a lower prevalence of congestive heart failure (15% vs. 30%; p = 0.004), death in-hospital (4% vs. 18%; p = 0.001) or after 1 year follow-up (6% vs. 20%; p = 0.01) than IE due to other pathogens (n = 5514). On multivariable analysis, stroke was associated with mitral valve vegetations (OR 3.60; CI 1.34-9.65; p<0.01) and younger age (OR 0.62; CI 0.49-0.90; p<0.01). The overall outcome of HE was excellent with the in-hospital mortality (4%) significantly better than for non-HE (18%; p<0.001). Prosthetic valve endocarditis was more common in HE (35%) than non-HE (24%). The outcome of prosthetic valve and native valve HE was excellent whether treated medically or with surgery. Current treatment is very successful for the management of both native valve prosthetic valve HE but further studies are needed to determine why HE has a predilection for younger people and to cause stroke. The small number of patients and observational design limit inferences on treatment strategies. Self selection of study sites limits epidemiological inferences.

Abstract

Background. Triggering receptor expressed on myeloid cells-1 (TREM-1) is a cell-surface molecule that has been identified on both human and murine polymorphonuclear neutrophils and mature monocytes. The activation of TREM-1 in the presence of microbial components amplifies the inflammatory response and may be responsible for the hyperresponsiveness observed during the initial stage of sepsis. The aim of the present study was to investigate the effect of the modulation of the TREM-1 pathway during experimental pneumonia in rats.Methods. Adult male Wistar rats were intratracheally inoculated with Pseudomonas aeruginosa (PAO1 strain) and randomly treated or not treated with an analogue synthetic peptide derived from the extracellular moiety of TREM-1 (LP17).Results. P. aeruginosa induced a severe pneumonia associated with signs of severe sepsis within the first 24 h. In septic rats, LP17 improved hemodynamic status, attenuated the development of lactic acidosis and hypoxemia, modulated lung and systemic inflammatory responses and coagulation activation, reduced lung histological damage, and improved survival.Conclusions. The modulation of the TREM-1 pathway by the use of such synthetic peptides as LP17 appears beneficial during P. aeruginosa pneumonia in rats in attenuating lung and systemic inflammatory responses.

Abstract

On the subcortical development of the pine pest, Pissodes notatus F. (Col., Curculionidae). II. Evidence of a facultative diapause The underbark development of P. notatus during winter was regulated by two main factors resulting in its dormancy: on the one hand, a thermic quiescence which stopped the growth of every stage, and, on the other hand, a facultative diapause involving the fourth larval stage. This diapause occurred only on the brood of adults which laid eggs during a decreasing daylength, and when the larvae of which were submitted to low temperatures during a sufficiently long period. Ecological consequences of these characteristics are discussed. Zusammenfassung Zur subkortikalen Entwicklung des Kiefernschädlings Pissodes notatus F. (Col., Curculionidae). II. Nachweis einer fakultativen Diapause Die Entwicklung von P. notatus unter der Rinde während des Winters wurde durch zwei Hauptfaktoren reguliert, die in einer Dormanz resultierten: eine thermische Quieszenz, die das Wachstum in jedem Larvenstadium stoppt sowie eine fakultative Diapause während des vierten Larvenstadiums. Diese Diapause tritt nur bei der Brut solcher Adulten auf, die ihre Eier während abnehmender Tägeslänge ablegten und die daraus schlüpfenden Larven ausreichend lange einer niedrigen Temperatur ausgesetzt waren. öml;kologische Konsequenzen dieser Kriterien werden diskutiert.

43. Metronidazole Resistance in Prevotellaspp. and Description of a New nimGene in Prevotella baroniae

Author

Abstract

ABSTRACTNonduplicate clinical isolates of Prevotellaspp. recovered from patients hospitalized between 2003 and 2006 in two French tertiary-care teaching hospitals were investigated for their susceptibility to metronidazole and the presence of nimgenes. Of the 188 strains tested, 3 isolates displayed reduced susceptibility to metronidazole after 48 h of incubation, while 27 additional isolates exhibited heterogeneous resistance after prolonged incubation; all 30 of the isolates were nimnegative. Among the remaining 158 isolates, 7 nim-positive isolates were detected. All of these strains were identified as Prevotella baroniaeby 16S rRNA gene sequence analysis and contained a new nimgene, named nimI, as determined by DNA sequence analysis. Chromosomal localization of this single-copy gene was demonstrated in all clinical isolates as well as in type strain P. baroniaeDSM 16972 by using Southern hybridization. No known associated insertion sequence elements were detected upstream of the nimIgene in any of the nim-positive strains by PCR mapping. After prolonged exposure to metronidazole, stable resistant subpopulations could be selected in nimI-positive Prevotellaisolates (n= 6) as well as in nim-negative Prevotellaisolates (n= 6), irrespective of their initial susceptibility to this antibiotic. This study is the first description of a new nitroimidazole resistance gene in P. baroniaewhich seems to be silent and which might be intrinsic in this species. Moreover, our findings highlight the fact that high-level resistance to metronidazole may be easily induced in both nim-positive and nim-negative Prevotellasp. strains.

46. Evidence for a marking pheromone in host discrimination by Cephalonomia Stephanoderis (Hym.: Bethylidae)

Author

Barrera, J., Gomez, J., and Alauzet, C.

Abstract

Abstract: The bethylidCephalonomia stephanoderis Betrem is an ectoparasitoid that prefers to oviposit on the prepupae and pupae of the coffe berry borerHypothenemus hampei (Ferrari) (Coleoptera: Scolytidae). It has the ability to distinguish unparasitized from parasitized hosts and rarely lays more than one egg per host. The mechanism of this host discrimination byC. stephanoderis was investigated under laboratory conditions. For this, parasitoid eggs that had been deposited on host pupae were removed and pupae were then offered (individually and collectively) to individual female wasps. A total of 92% of individually offered hosts and 93% of collectively offered hosts were not parasitized. It is concluded thatC. stephanoderis recognizes a marking pheromone deposited into or onto the host, preceding, during, or after oviposition which enables female parasitoids to avoid self and conspecific superparasitism.

Alauzet, C., Dargagnon, D., and Malausa, J.

Abstract

Abstract: The main characteristics of the imaginal and preimaginal development and the reproduction ofOrius laevigatus were studied at 15, 20, 25 and 30°C. Temperature greatly influences the developmental and reproductive biology of this species. The lowest developmental threshold is 10,6°C. Reproduction is greatly reduced at 15°C relative to the higher temperatures tested. O. laevigatus is well adapted to relatively high temperature conditions. The best development and reproduction rates are observed between 20 and 30°C with a theoretical optimum at 26°C.

48. Dynamique des populationsd'un ravageur des pins: Pissodes notatus F. [ Col.: Curculionidae ] II. — Rôle du parasitisme

Author

Alauzet, C.

Abstract

Résumé: L'étude examine l'influence du cortège parasitaire dans la dynamique des populations deP. notatus dans une forêt de pin maritime du sud-ouest de la France. De 1968 à 1977, le niveau du parasitisme apparent total à l'émergence a varié, mais est resté le plus souvent compris entre 20 et 30%. Les parasitoïdes les plus abondants appartenant aux genresEubazus etCoeloïdes se sont montrés densito-dépendants par rapport à leur hôte et le rapport entre leurs effectifs respectifs est resté assez constant au cours des 10 années d'observation. Un calcul basé sur l'évolution théorique des populations deP. notatus au vours de leur développement a permis d'estimer qu'en moyenne 16% seulement des charançons étaient détruits chaque année par l'ensemble des parasitoïdes alors que dans cet habitat le taux de parasitisme annuel moyen à l'émergence a été de 0,28.

Abstract

Résumé: En se fondant sur l'étude des potentialités biotiques d'Orius majusculus (Rt.), on a pu dégager les conditions optimales d'élevage de cet insecte. Avec une alimentation à base d'œufs d'Anagasta kuehniella (Z.) et un support de ponte constitué par des feuilles de géranium (Pelargonium peltatum Soland. in Ait.), l'élevage de ce prédateur donne un rendement suffisant s'il est mené entre 15 et 25 °C et sous une photopériode dépassant 14 h d'éclairement par 24 h. Pour une manipulation réduite, un appareillage peu sophistiqué et de faible encombrement, cet élevage donne des résultats satisfaisants. Dans les conditions de production adoptées, le coefficient de multiplication d'une femelle élevée pendant quatre semaines a été voisin de 20.
