Exclusive Oral Antibiotic Treatment for Hospitalized Community-Acquired Pneumonia: A Post-Hoc Analysis of a Randomized Clinical Trial. Clin Microbiol Infect 2024:S1198-743X(24)00237-4. [PMID: 38734138 DOI: 10.1016/j.cmi.2024.05.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/09/2023] [Revised: 04/09/2024] [Accepted: 05/05/2024] [Indexed: 05/13/2024]
Abstract
OBJECTIVES In this study, we aimed to assess the efficacy of different ways of administration and types of beta-lactams for hospitalized community-acquired pneumonia (CAP). METHODS In this post-hoc analysis of a RCT on patients hospitalized for CAP (PTC trial) comparing 3-day versus 8-day durations of beta-lactams, which concluded to non-inferiority, we included patients who received either amoxicillin-clavulanate (AMC) or third-generation cephalosporin (3GC) regimens, and exclusively either intravenous or oral treatment for the first 3 days (followed by either 5 days of oral placebo or AMC according to randomization). Choice of route and molecule was left to the physician in charge. The main outcome was failure at 15 days after first antibiotic intake, defined as temperature>37.9°C, and/or absence of resolution/improvement of respiratory symptoms, and/or additional antibiotic treatment for any cause. The primary outcome according to route of administration was evaluated through logistic regression. Inverse probability treatment weighting (IPTW) with a propensity score model was used to adjust for non-randomization of treatment route and potential confounders. The difference in failure rates was also evaluated among several sub-populations (AMC versus 3GC treatments, or intravenous versus oral AMC, patients with multi-lobar infection, patients aged ≥ 65 years old, and patients with CURB65 scores of 3-4). RESULTS We included 200 patients from the original trial, with 93/200 (46.5%) patients only treated with intravenous treatment and 107/200 (53.5%) patients only treated with oral therapy. Failure rate at Day 15 was not significantly different among patients treated with initial intravenous versus oral treatment (25/93 (26.9%) versus 28/107 (26.2%), aOR 0.973 (95%CI 0.519-1.823), p=0.932). Failure rates at Day 15 were not significantly different among the subgroup populations. CONCLUSIONS Among hospitalized patients with CAP, there was no significant difference in efficacy between initial intravenous and exclusive oral treatment. TRIAL REGISTRATION This trial is registered with ClinicalTrials.gov, NCT01963442.

Efficacy and safety of an early oral switch in low-risk Staphylococcus aureus bloodstream infection (SABATO): an international, open-label, parallel-group, randomised, controlled, non-inferiority trial. THE LANCET. INFECTIOUS DISEASES 2024; 24:523-534. [PMID: 38244557 DOI: 10.1016/s1473-3099(23)00756-9] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/03/2023] [Revised: 11/30/2023] [Accepted: 12/01/2023] [Indexed: 01/22/2024]
Abstract
BACKGROUND Staphylococcus aureus bloodstream infection is treated with at least 14 days of intravenous antimicrobials. We assessed the efficacy and safety of an early switch to oral therapy in patients at low risk for complications related to S aureus bloodstream infection. METHODS In this international, open-label, randomised, controlled, non-inferiority trial done in 31 tertiary care hospitals in Germany, France, the Netherlands, and Spain, adult patients with low-risk S aureus bloodstream infection were randomly assigned after 5-7 days of intravenous antimicrobial therapy to oral antimicrobial therapy or to continue intravenous standard therapy. Randomisation was done via a central web-based system, using permuted blocks of varying length, and stratified by study centre. The main exclusion criteria were signs and symptoms of complicated S aureus bloodstream infection, non-removable foreign devices, and severe comorbidity. The composite primary endpoint was the occurrence of any complication related to S aureus bloodstream infection (relapsing S aureus bloodstream infection, deep-seated infection, and mortality attributable to infection) within 90 days, assessed in the intention-to-treat population by clinical assessors who were masked to treatment assignment. Adverse events were assessed in all participants who received at least one dose of study medication (safety population). Due to slow recruitment, the scientific advisory committee decided on Jan 15, 2018, to stop the trial after 215 participants were randomly assigned (planned sample size was 430 participants) and to convert the planned interim analysis into the final analysis. The decision was taken without knowledge of outcome data, at a time when 126 participants were enrolled. The new sample size accommodated a non-inferiority margin of 10%; to claim non-inferiority, the upper bound of the 95% CI for the treatment difference (stratified by centre) had to be below 10 percentage points. The trial is closed to recruitment and is registered with ClinicalTrials.gov (NCT01792804), the German Clinical trials register (DRKS00004741), and EudraCT (2013-000577-77). FINDINGS Of 5063 patients with S aureus bloodstream infection assessed for eligibility, 213 were randomly assigned to switch to oral therapy (n=108) or to continue intravenous therapy (n=105). Mean age was 63·5 (SD 17·2) years and 148 (69%) participants were male and 65 (31%) were female. In the oral switch group, 14 (13%) participants met the primary endpoint versus 13 (12%) in the intravenous group, with a treatment difference of 0·7 percentage points (95% CI -7·8 to 9·1; p=0·013). In the oral switch group, 36 (34%) of 107 participants in the safety population had at least one serious adverse event compared with 27 (26%) of 103 participants in the intravenous group (p=0·29). INTERPRETATION Oral switch antimicrobial therapy was non-inferior to intravenous standard therapy in participants with low-risk S aureus bloodstream infection. However, it is necessary to carefully assess patients for signs and symptoms of complicated S aureus bloodstream infection at the time of presentation and thereafter before considering early oral switch therapy.

Abstract
BACKGROUND Community-acquired bacterial meningitis is a rare but severe central nervous system infection that may be associated with cerebrovascular complications (CVC). Our objective is to assess the prevalence of CVC in patients with community-acquired bacterial meningitis and to determine the first-48 h factors associated with CVC. METHODS We analyzed data from the prospective multicenter cohort study (COMBAT) including, between February 2013 and July 2015, adults with community-acquired bacterial meningitis. CVC were defined by the presence of clinical or radiological signs (on cerebral CT or MRI) of focal clinical symptom. Factors associated with CVC were identified by multivariate logistic regression. RESULTS CVC occurred in 128 (25.3%) of the 506 patients in the COMBAT cohort (78 (29.4%) of the 265 pneumococcal meningitis, 17 (15.3%) of the 111 meningococcal meningitis, and 29 (24.8%) of the 117 meningitis caused by other bacteria). The proportion of patients receiving adjunctive dexamethasone was not statistically different between patients with and without CVC (p = 0.84). In the multivariate analysis, advanced age (OR = 1.01 [1.00-1.03], p = 0.03), altered mental status at admission (OR = 2.23 [1.21-4.10], p = 0.01) and seizure during the first 48 h from admission (OR = 1.90 [1.01-3.52], p = 0.04) were independently associated with CVC. CONCLUSIONS CVC were frequent during community-acquired bacterial meningitis and associated with advanced age, altered mental status and seizures occurring within 48 h from admission but not with adjunctive corticosteroids.

Abstract
BACKGROUND Telephone hotlines in infectious diseases (ID) are part of antimicrobial stewardship programs designed to provide support and expertise in ID and to control antibiotic resistance. The aim of the study was to characterize the activity of the ID hotlines and estimate their usefulness for general practitioners (GPs). METHODS This was a multicenter prospective observational study in different French regions. ID teams involved in antimicrobial stewardship with a hotline for GPs were asked to record their advice from April 2019 to June 2022. In these regions, all GPs were informed of the ID hotline's operating procedures. The main outcome was usage rate of the hotlines by GPs. RESULTS Ten volunteer ID teams collected 4138 requests for advice from 2171 GPs. The proportion of GPs using the hotline varied pronouncedly by region, from 54% in the Isere department, to less than 1% in departments with the lowest usage. These differences were associated with the number of physicians in ID teams and with the age of the hotline. These results highlighted the value of working time as a means of ensuring the permanence of expertise. The main reasons for calling were: a diagnostic question (44%); choice of antibiotic (31%). The ID specialist provided advice on antibiotic therapy (43%) or a proposal for specialized consultation or hospitalization (11%). CONCLUSIONS ID hotlines could help to strengthen cooperation between primary care and hospital medicine. However, the deployment and perpetuation of this activity require reflection concerning its institutional and financial support.

Abstract
BACKGROUND P. aeruginosa bacteremia is a common and severe infection carrying high mortality in older adults. We aimed to evaluate outcomes of P. aeruginosa bacteremia among old adults (≥ 80 years). METHODS We included the 464/2394 (19%) older adults from a retrospective multinational (9 countries, 25 centers) cohort study of individuals hospitalized with P. aeruginosa bacteremia. Bivariate and multivariable logistic regression models were used to evaluate risk factors for 30-day mortality among older adults. RESULTS Among 464 adults aged ≥ 80 years, the mean age was 84.61 (SD 3.98) years, and 274 (59%) were men. Compared to younger patients, ≥ 80 years adults had lower Charlson score; were less likely to have nosocomial acquisition; and more likely to have urinary source. Thirty-day mortality was 30%, versus 27% among patients 65-79 years (n = 894) and 25% among patients < 65 years (n = 1036). Multivariate analysis for predictors of mortality among patients ≥ 80 years, demonstrated higher SOFA score (odds ratio [OR] 1.36, 95% confidence interval [CI] 1.23-1.51, p < 0.001), corticosteroid therapy (OR 3.15, 95% CI: 1.24-8.01, p = 0.016) and hospital acquired P. aeruginosa bacteremia (OR 2.30, 95% CI: 1.33-3.98, p = 0.003) as predictors. Appropriate empirical therapy within 24 h, type of definitive anti-pseudomonal drug, and type of regimen (monotherapy or combination) were not associated with 30-day mortality. CONCLUSIONS In older adults with P. aeruginosa bacteremia, background conditions, place of acquisition, and disease severity are associated with mortality, rather than the antimicrobial regimen. In this regard, preventive efforts and early diagnosis before organ failure develops might be beneficial for improving outcomes.

Abstract
BACKGROUND Treating pneumonia in old patients remains challenging for clinicians. Moreover, bacterial antimicrobial resistance is a major public health threat. OBJECTIVE The PROPAGE study evaluated the interest of a strategy using serial measurements of procalcitonin (PCT) to reduce the duration of antibiotic therapy in old patients with pneumonia. METHODS PROPAGE took place from Dec.-2013 to Jun.-2016 in eight French geriatric units. It was a prospective, comparative, randomised, open-label study involving old patients (≥ 80 years) who had initiated antibiotic treatment for pneumonia in the previous 48 h. PCT was monitored in all patients and two decision-making PCT-based algorithms guided antibiotic therapy in patients from the PCT group. RESULTS 107 patients were randomised (PCT, n = 50; Control, n = 57). Antibiotic therapy exposure was reduced in the PCT group as compared to the Control group (median duration of antibiotic therapy, 8 vs. 10 days [rank-test, p = 0.001]; antibiotic persistence rates on Days 6 and 8, 54% and 44% vs. 91% and 72%) and no significant difference was found in recovery rate (84% vs. 89.5%; Pearson Chi² test, p = 0.402). CONCLUSION Although, the superiority of the strategy was not tested using a composite criterion combining antibiotic therapy duration and recovery rate was not tested due to the small sample size, the present study showed that monitoring associated with PCT-guided algorithm could help shorten antibiotic treatment duration in the very old patients without detrimental effects. Measuring PCT levels between Day 4 and Day 6 could be helpful when making the decision regarding antibiotic discontinuation. TRIAL REGISTRATION NCT02173613.

Abstract
Abstract
Background
People living with HIV (PLWH) have a higher risk of CAD. Whether coronary artery calcification (CAC) score could better stratify the CV risk remains debated in this middle age population.
Purpose
We conducted the French CAC score study to compare the CAC score between PLHIV and HIV− subjects at intermediate risk.
Methods
689 subjects (257 PLHIV and 432 HIV−) were consecutively addressed for CV risk evaluation including CAC score assessment in 2 centers between 2013 and 2019. Subjects were included if they were 18 years'old or older, had no known cardiovascular disease and had a CAC score along with cardiometabolic assessment.
Results
The mean age of the cohort was 59.3 years ± 10.7 and predominantly male (54%). PLHIV were younger (55.8 years ± 9.1 vs 61.3±11.3, p<0.004), with a lower rate of diabetics (18% vs 26%, p=0.009) and lower levels of total cholesterol, LDLc, and HDLc (2.0 mmol/l vs, 2.2 mmol/l; 1.2 mmol/L vs 1.3 mmol/L; and 1.2 mmol/L vs 1.4 mol/L respectively, all p<0.001). The prevalence of hypertension, dyslipidemia and obesity was similar between PLHIV and the HIV− group (40%, 43% and 21%, respectively). No differences were observed in CV therapies prescribed including antihypertensive drugs and statins between PLHIV and the HIV− group (39% vs 37%, p=0.54 and 46% vs 39%, p=0.065). In contrast, PLHIV had higher rate of triglycerides (1.4 mmol/L vs 1.2 mmol/L, p=0.01), higher rate of active smoking (28% vs 14%, p<0.001), CRP level (4.0 mg/L vs 2.9 mg/L, p<0.001) along with higher black ethnicity representation (17% vs 5%;, p<0.001). 96% of PLHIV were under antiretroviral therapy at the time of enrollment with 88% who had been exposed to protease inhibitors. In subjects who had carotid and/or limb ultrasound evaluation (67% and 45% respectively in PLHIV and HIV), no increased rate of arterial stenosis >50% was found (13% vs 8%, p=0.16). Concerning, CV risk estimation using 10-year ASCVD and HEART scores, we observed that the median ASCVD score was similar between PLHIV and HIV− group (10.7% vs 9.8, p=0.15) but that PLHIV had a higher HEART score (3.0% vs 2.0%, p<0.001). The repartition between the ASCVD or HEART scores classes between the 2 groups was similar with 80% of the cohort classified as low or intermediate CV risk with the ASCVD score and 88% at intermediate or borderline CV risk with the HEART score. However, no statistically significant differences was found between the 2 groups regarding the prevalence of CAC = 0 (41% vs 44%, p=0.52) and the median CAC score (7.7 vs 8.2, p=0.81).
Conclusion
In this cohort of subjects at intermediate CV risk according to CV risk scores estimation (ASCVD or HEART scores), PLHIV had a similar prevalence of CAC = 0 and median CAC scores as compared to HIV− subjects despite a younger age (6 years). Longitudinal follow up will explore whether this similar CAC score evaluation will be translated into higher CV events.

Abstract
INTRODUCTION There is no consensus regarding optimal duration of antibiotic therapy for Pseudomonas aeruginosa bacteremia. We aimed to evaluate the impact of short antibiotic course. METHODS We present a retrospective multicenter study including patients with P. aeruginosa bacteremia during 2009-2015. We evaluated outcomes of patients treated with short (6-10 days) versus long (11-15 days) antibiotic courses. The primary outcome was a composite of 30-day mortality or bacteremia recurrence and/or persistence. Univariate and inverse probability treatment-weighted (IPTW) adjusted multivariate analysis for the primary outcome was performed. To avoid immortal time bias, the landmark method was used. RESULTS We included 657 patients; 273 received a short antibiotic course and 384 a long course. There was no significant difference in baseline characteristics of patients. The composite primary outcome occurred in 61/384 patients in the long-treatment group (16%) versus 32/273 in the short-treatment group (12%) (p = 0.131). Mortality accounted for 41/384 (11%) versus 25/273 (9%) of cases, respectively. Length of hospital stay was significantly shorter in the short group [median 13 days, interquartile range (IQR) 9-21 days, versus median 15 days, IQR 11-26 days, p = 0.002]. Ten patients in the long group discontinued antibiotic therapy owing to adverse events, compared with none in the short group. On univariate and multivariate analyses, duration of therapy was not associated with the primary outcome. CONCLUSIONS In this retrospective study, 6-10 days of antibiotic course for P. aeruginosa bacteremia were as effective as longer courses in terms of survival and recurrence. Shorter therapy was associated with reduced length of stay and less drug discontinuation.

Abstract
IMPORTANCE Failure of treatment is the most serious complication in community-acquired pneumonia (CAP). OBJECTIVE To assess the potential risk factors for treatment failure in clinically stable patients with CAP. DESIGN, SETTING, AND PARTICIPANTS This secondary analysis assesses data from a randomized clinical trial on CAP (Pneumonia Short Treatment [PTC] trial) conducted from December 19, 2013, to February 1, 2018. Data analysis was performed from July 18, 2019, to February 15, 2020. Patients hospitalized at 1 of 16 centers in France for moderately severe CAP who were clinically stable at day 3 of antibiotic treatment were included in the PTC trial and analyzed in the per-protocol trial population. INTERVENTIONS Patients were randomly assigned (1:1) on day 3 of antibiotic treatment to receive β-lactam (amoxicillin-clavulanate [1 g/125 mg] 3 times daily) or placebo for 5 extra days. MAIN OUTCOMES AND MEASURES The main outcome was failure at 15 days after first antibiotic intake, defined as a temperature greater than 37.9 °C and/or absence of resolution or improvement of respiratory symptoms and/or additional antibiotic treatment for any cause. The association among demographic characteristics, baseline clinical and biological variables available (ie, at the first day of β-lactam treatment), and treatment failure at day 15 among the per-protocol trial population was assessed by univariate and multivariable logistic regressions. RESULTS Overall, 310 patients were included in the study; this secondary analysis comprised 291 patients (174 [59.8%] male; mean [SD] age, 69.6 [18.5] years). The failure rate was 26.8%. Male sex (odds ratio [OR], 1.74; 95% CI, 1.01-3.07), age per year (OR, 1.03; 95% CI, 1.01-1.05), Pneumonia Severe Index score (OR, 1.01; 95% CI, 1.00-1.02), the presence of chronic lung disease (OR, 1.85; 95% CI, 1.03-3.30), and creatinine clearance (OR, 0.99; 95% CI, 0.98-1.00) were significantly associated with failure in the univariate analysis. When the Pneumonia Severe Index score was excluded to avoid collinearity with age and sex in the regression model, only male sex (OR, 1.92; 95% CI, 1.08-3.49) and age (OR, 1.02; 95% CI, 1.00-1.05) were associated with failure in the multivariable analysis. CONCLUSIONS AND RELEVANCE In this secondary analysis of a randomized clinical trial, among patients with CAP who reached clinical stability after 3 days of antibiotic treatment, only male sex and age were associated with higher risk of failure, independent of antibiotic treatment duration and biomarker levels. Another randomized clinical trial is needed to evaluate the impact of treatment duration in populations at higher risk for treatment failure.

Abstract
Introduction L’objectif de notre étude était d’évaluer la séroprévalence SARS-Cov-2 chez les professionnels de santé, après la première vague Covid-19, et d’analyser les facteurs professionnels et extraprofessionnels modifiant cette prévalence. Matériels et méthodes Suite aux instructions gouvernementales proposant de réaliser une sérologie Covid-19 à tout professionnel de santé après la première vague, nous avons réalisé une étude transversale, multicentrique. Tous les professionnels volontaires des quatre centres participants étaient invités à réaliser une sérologie et à remplir un questionnaire concernant leurs données démographiques, leurs caractéristiques professionnelles, l’utilisation des équipements de protection individuelle et l’exposition extra professionnelle au Covid-19. Nous avons calculé la prévalence SARS-Cov-2 et utilisé une régression logistique en appliquant un effet centre. Résultats Un total de 3454 professionnels ont participé à l’étude dont 83,4 % de femmes. L’âge moyen était de 40,6 ans [31,8–50,3]. En médiane, la prévalence sérologique SARS-Cov-2 était de 5 % (95 % IC, 4,3 %–5,8 %). Les facteurs associés à une plus forte séroprévalence étaient : l’âge < 30 ans (aOR = 1,59, (95 % IC, 1,06–2,37)), le statut d’étudiant (aOR = 3,38, (95 % IC, 1,62–7,05)) avec une séroprévalence de 16,9 % dans cette catégorie. L’unité de travail, y compris le fait d’avoir travaillé en unité Covid ou en réanimation, ainsi que l’exposition à des patients (quel que soit leur statut infectieux) n’étaient pas associé à une augmentation de la séroprévalence. Par contre les professionnels rapportant un contact avec un patient Covid, sans protection adaptée, ou ayant pratiqué des taches aérosolisantes, y compris avec un masque FFP2, avaient un surrisque d’infection Covid-19 (respectivement aOR à 1,66 et 1,7). Enfin, l’exposition à un collègue infecté ou à un cas familial était également associée à une augmentation de la prévalence sérologique. Conclusion Les mesures mises en place pour limiter la transmission du SARS-Cov-2 des patients aux professionnels de santé semblent efficaces. En complément de la vaccination, l’éviction systématique des professionnels infectés, la formation des étudiants et le rappel des mesures d’hygiène durant les temps de pause pourraient limiter la contamination des professionnels de santé.

[PMID: 34451949 PMCID: PMC8402428 DOI: 10.3390/vaccines9080824] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/10/2021] [Revised: 07/05/2021] [Accepted: 07/22/2021] [Indexed: 01/09/2023] Open
Abstract
We aimed to report SARS-CoV-2 seroprevalence after the first wave of the pandemic among healthcare workers, and to explore factors associated with an increased infection rate. We conducted a multicentric cross-sectional survey from 27 June to 31 September 2020. For this survey, we enrolled 3454 voluntary healthcare workers across four participating hospitals, of which 83.4% were female, with a median age of 40.6 years old (31.8-50.3). We serologically screened the employees for SARS-CoV-2, estimated the prevalence of infection, and conducted binomial logistic regression with random effect on participating hospitals to investigate associations. We estimated the prevalence of SARS-CoV-2 infection at 5.0% (95 CI, 4.3%-5.8%). We found the lowest prevalence in health professional management support (4.3%) staff. Infections were more frequent in young professionals below 30 years old (aOR = 1.59, (95 CI, 1.06-2.37)), including paramedical students and residents (aOR = 3.38, (95 CI, 1.62-7.05)). In this group, SARS-CoV-2 prevalence was up 16.9%. The location of work and patient-facing role were not associated with increased infections. Employees reporting contacts with COVID-19 patients without adequate protective equipment had a higher rate of infection (aOR = 1.66, (95 CI, 1.12-2.44)). Aerosol-generating tasks were associated with a ~1.7-fold rate of infection, regardless of the uptake of FFP2. Those exposed to clusters of infected colleagues (aOR = 1.77, (95 CI, 1.24-2.53)) or intra-familial COVID-19 relatives (aOR = 2.09, (95 CI, 1.15-3.80)) also had a higher likelihood of infection. This report highlights that a sustained availability of personal protective equipment limits the SARS-CoV-2 infection rate to what is measured in the general population. It also pinpoints the need for dedicated hygiene training among young professionals, justifies the systematic eviction of infected personnel, and stresses the need for interventions to increase vaccination coverage among any healthcare workers.

Combination versus monotherapy as definitive treatment for Pseudomonas aeruginosa bacteraemia: a multicentre retrospective observational cohort study. J Antimicrob Chemother 2021; 76:2172-2181. [PMID: 33993273 DOI: 10.1093/jac/dkab134] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/19/2021] [Accepted: 03/31/2021] [Indexed: 02/05/2023] Open
Abstract
BACKGROUND Pseudomonas aeruginosa bacteraemia is a common and serious infection. No consensus exists regarding whether definitive combination therapy is superior to monotherapy. We aimed to evaluate the impact of combination therapy on mortality. METHODS This was a multicentre retrospective study (nine countries, 25 centres), including 1277 patients with P. aeruginosa bacteraemia during 2009-15. We evaluated the association between β-lactam plus aminoglycoside or quinolone combination therapy versus β-lactam monotherapy and mortality. The primary outcome was 30 day all-cause mortality. Univariate and multivariate Cox regression analyses were conducted, introducing combination as a time-dependent variable. Propensity score was conducted to adjust for confounding for choosing combination therapy over monotherapy. RESULTS Of 1119 patients included, 843 received definitive monotherapy and 276 received combination therapy (59% aminoglycoside and 41% quinolone). Mortality at 30 days was 16.9% (189/1119) and was similar between combination (45/276; 16.3%) and monotherapy (144/843; 17.1%) groups (P = 0.765). In multivariate Cox regression, combination therapy was not associated with reduced mortality (HR 0.98, 95% CI 0.64-1.53). No advantage in terms of clinical failure, microbiological failure or recurrent/persistent bacteraemia was demonstrated using combination therapy. Likewise, adverse events and resistance development were similar for the two regimens. CONCLUSIONS In this retrospective cohort, no mortality advantage was demonstrated using combination therapy over monotherapy for P. aeruginosa bacteraemia. Combination therapy did not improve clinical or microbiological failure rates, nor affect adverse events or resistance development. Our finding of no benefit with combination therapy needs confirmation in well-designed randomized controlled trials.

Discontinuing β-lactam treatment after 3 days for patients with community-acquired pneumonia in non-critical care wards (PTC): a double-blind, randomised, placebo-controlled, non-inferiority trial. Lancet 2021; 397:1195-1203. [PMID: 33773631 DOI: 10.1016/s0140-6736(21)00313-5] [Citation(s) in RCA: 68] [Impact Index Per Article: 22.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/25/2020] [Revised: 01/21/2021] [Accepted: 02/03/2021] [Indexed: 12/13/2022]
Abstract
BACKGROUND Shortening the duration of antibiotic therapy for patients admitted to hospital with community-acquired pneumonia should help reduce antibiotic consumption and thus bacterial resistance, adverse events, and related costs. We aimed to assess the need for an additional 5-day course of β-lactam therapy among patients with community-acquired pneumonia who were stable after 3 days of treatment. METHODS We did this double-blind, randomised, placebo-controlled, non-inferiority trial (the Pneumonia Short Treatment [PTC]) in 16 centres in France. Adult patients (aged ≥18 years) admitted to hospital with moderately severe community-acquired pneumonia (defined as patients admitted to a non-critical care unit) and who met prespecified clinical stability criteria after 3 days of treatment with β-lactam therapy were randomly assigned (1:1) to receive β-lactam therapy (oral amoxicillin 1 g plus clavulanate 125 mg three times a day) or matched placebo for 5 extra days. Randomisation was done using a web-based system with permuted blocks with random sizes and stratified by randomisation site and Pneumonia Severity Index score. Participants, clinicians, and study staff were masked to treatment allocation. The primary outcome was cure 15 days after first antibiotic intake, defined by apyrexia (temperature ≤37·8°C), resolution or improvement of respiratory symptoms, and no additional antibiotic treatment for any cause. A non-inferiority margin of 10 percentage points was chosen. The primary outcome was assessed in all patients who were randomly assigned and received any treatment (intention-to-treat [ITT] population) and in all patients who received their assigned treatment (per-protocol population). Safety was assessed in the ITT population. This study is registered with ClinicalTrials.gov, NCT01963442, and is now complete. FINDINGS Between Dec 19, 2013, and Feb 1, 2018, 706 patients were assessed for eligibility, and after 3 days of β-lactam treatment, 310 eligible patients were randomly assigned to receive either placebo (n=157) or β-lactam treatment (n=153). Seven patients withdrew consent before taking any study drug, five in the placebo group and two in the β-lactam group. In the ITT population, median age was 73·0 years (IQR 57·0-84·0) and 123 (41%) of 303 participants were female. In the ITT analysis, cure at day 15 occurred in 117 (77%) of 152 participants in the placebo group and 102 (68%) of 151 participants in the β-lactam group (between-group difference of 9·42%, 95% CI -0·38 to 20·04), indicating non-inferiority. In the per-protocol analysis, 113 (78%) of 145 participants in the placebo treatment group and 100 (68%) of 146 participants in the β-lactam treatment group were cured at day 15 (difference of 9·44% [95% CI -0·15 to 20·34]), indicating non-inferiority. Incidence of adverse events was similar between the treatment groups (22 [14%] of 152 in the placebo group and 29 [19%] of 151 in the β-lactam group). The most common adverse events were digestive disorders, reported in 17 (11%) of 152 patients in the placebo group and 28 (19%) of 151 patients in the β-lactam group. By day 30, three (2%) patients had died in the placebo group (one due to bacteraemia due to Staphylococcus aureus, one due to cardiogenic shock after acute pulmonary oedema, and one due to heart failure associated with acute renal failure) and two (1%) in the β-lactam group (due to pneumonia recurrence and possible acute pulmonary oedema). INTERPRETATION Among patients admitted to hospital with community-acquired pneumonia who met clinical stability criteria, discontinuing β-lactam treatment after 3 days was non-inferior to 8 days of treatment. These findings could allow substantial reduction of antibiotic consumption. FUNDING French Ministry of Health.

Abstract
Introduction Dans le contexte d’infections à COVID-19 en Chine depuis décembre 2019, nous avons créé une procédure de prélèvement et de prise en charge des cas possibles. La nuit du 6 au 7 février, le SAMU déclenche une alerte pour 2 patients, en contact avec un cas confirmé COVID-19 dans les 14 jours précédents et consultant pour une infection respiratoire haute. Matériels et méthodes Nous décrivons la gestion de l’alerte, la création d’une cellule de crise locale pluridisciplinaire et les interactions avec les différentes instances régionales et nationales. Résultats En l’absence de signes de gravité, les 2 patients rentrent à domicile pour confinement avec 11 autres personnes exposées. En concertation avec l’ARS, des prélèvements pour tous, symptomatiques ou non, sont réalisés au domicile le 7 février par un médecin et une IDE d’infectiologie. Cinq sont positifs à COVID-19 le soir même. Ceci entraîne la création d’une cellule de crise locale composée des directions, de l’unité d’hygiène, d’infectiologues, du SAMU, des urgences, de microbiologistes et de pédiatres, en lien avec les instances territoriales, régionales et nationales lors de conférences téléphoniques pluriquotidiennes. Les cas confirmés sont hospitalisés dans 3 CHU proches pour maintenir les capacités d’accueil dans les 2 CH de proximité. Le contact tracing est assuré par les ARS territoriale et régionale et la DGS (pour l’étranger). Les principales actions de la cellule de crise locale sont la mise en place : – d’une stratégie progressive, raisonnée, adaptable à l’évolution de la situation sans céder à la panique ; – d’un circuit extérieur dédié pour les urgences (pour afflux éventuel de patients) ; – de secteurs d’hospitalisation pour cohorting des cas possibles ou confirmés ; – d’une campagne de prélèvements par des binômes infectiologues/paramédicaux dans le village où résident les cas confirmés le premier jour (91 faits, tous négatifs) puis dans le CH les jours suivants, pour les contacts à haut risque symptomatiques. Les points forts de cette organisation ont été la réactivité et la mobilisation générale des professionnels, la collaboration fluide avec l’ARS territoriale et la complémentarité médico-administrative. Les principales difficultés ressenties étaient en lien avec : – le nombre élevé de contacts, gérés par 3 instances différentes ; – le manque de transmission d’informations en temps réel aux équipes locales ; – l’inadéquation entre les impératifs du terrain et les consignes et concertations nécessaires aux niveaux supérieurs. Conclusion Cette expérience permet de souligner les forces et les faiblesses de la gestion locale d’un cluster de COVID-19. Une réunion de débriefing avec les différents acteurs sera pertinente afin d’améliorer le dispositif pour des situations semblables à l’avenir.

Ceftazidime, Carbapenems, or Piperacillin-tazobactam as Single Definitive Therapy for Pseudomonas aeruginosa Bloodstream Infection: A Multisite Retrospective Study. Clin Infect Dis 2020; 70:2270-2280.

Abstract
BACKGROUND The optimal antibiotic regimen for Pseudomonas aeruginosa bacteremia is controversial. Although β-lactam monotherapy is common, data to guide the choice between antibiotics are scarce. We aimed to compare ceftazidime, carbapenems, and piperacillin-tazobactam as definitive monotherapy. METHODS A multinational retrospective study (9 countries, 25 centers) including 767 hospitalized patients with P. aeruginosa bacteremia treated with β-lactam monotherapy during 2009-2015. The primary outcome was 30-day all-cause mortality. Univariate and multivariate, including propensity-adjusted, analyses were conducted introducing monotherapy type as an independent variable. RESULTS Thirty-day mortality was 37/213 (17.4%), 42/210 (20%), and 55/344 (16%) in the ceftazidime, carbapenem, and piperacillin-tazobactam groups, respectively. Type of monotherapy was not significantly associated with mortality in either univariate, multivariate, or propensity-adjusted analyses (odds ratio [OR], 1.14; 95% confidence interval [CI], 0.52-2.46, for ceftazidime; OR, 1.3; 95% CI, 0.67-2.51, for piperacillin-tazobactam, with carbapenems as reference in propensity adjusted multivariate analysis; 542 patients). No significant difference between antibiotics was demonstrated for clinical failure, microbiological failure, or adverse events. Isolation of P. aeruginosa with new resistance to antipseudomonal drugs was significantly more frequent with carbapenems (36/206 [17.5%]) versus ceftazidime (25/201 [12.4%]) and piperacillin-tazobactam (28/332 [8.4%] (P = .007). CONCLUSIONS No significant difference in mortality, clinical, and microbiological outcomes or adverse events was demonstrated between ceftazidime, carbapenems, and piperacillin-tazobactam as definitive treatment of P. aeruginosa bacteremia. Higher rates of resistant P. aeruginosa after patients were treated with carbapenems, along with the general preference for carbapenem-sparing regimens, suggests using ceftazidime or piperacillin-tazobactam for treating susceptible infection.

Risk factors for mortality among patients with Pseudomonas aeruginosa bacteraemia: a retrospective multicentre study. Int J Antimicrob Agents 2020; 55:105847. [PMID: 31770625 DOI: 10.1016/j.ijantimicag.2019.11.004] [Citation(s) in RCA: 31] [Impact Index Per Article: 7.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2019] [Revised: 11/06/2019] [Accepted: 11/13/2019] [Indexed: 02/08/2023]
Abstract
This study aimed to evaluate risk factors for 30-day mortality among hospitalised patients with Pseudomonas aeruginosa bacteraemia, a highly fatal condition. A retrospective study was conducted between 1 January 2009 and 31 October 2015 in 25 centres (9 countries) including 2396 patients. Univariable and multivariable analyses of risk factors were conducted for the entire cohort and for patients surviving ≥48 h. A propensity score for predictors of appropriate empirical therapy was introduced into the analysis. Of the 2396 patients, 636 (26.5%) died within 30 days. Significant predictors (odds ratio and 95% confidence interval) of mortality in the multivariable analysis included patient-related factors: age (1.02, 1.01-1.03); female sex (1.34, 1.03-1.77); bedridden functional capacity (1.99, 1.24-3.21); recent hospitalisation (1.43, 1.07-1.92); concomitant corticosteroids (1.33, 1.02-1.73); and Charlson comorbidity index (1.05, 1.01-1.93). Infection-related factors were multidrug-resistant Pseudomonas (1.52, 1.15-2.1), non-urinary source (2.44, 1.54-3.85) and Sequential Organ Failure Assessment (SOFA) score (1.27, 1.18-1.36). Inappropriate empirical therapy was not associated with increased mortality (0.81, 0.49-1.33). Among 2135 patients surviving ≥48 h, hospital-acquired infection (1.59, 1.21-2.09), baseline endotracheal tube (1.63, 1.13-2.36) and ICU admission (1.53, 1.02-2.28) were additional risk factors. Risk factors for mortality among patients with P. aeruginosa were mostly irreversible. Early appropriate empirical therapy was not associated with reduced mortality. Further research should be conducted to explore subgroups that may not benefit from broad-spectrum antipseudomonal empirical therapy. Efforts should focus on prevention of infection, mainly hospital-acquired infection and multidrug-resistant pseudomonal infection.

Abstract
Critically ill patients with infection in the intensive care unit (ICU) would certainly benefit from timely bacterial identification and effective antimicrobial treatment. Diagnostic techniques have clearly improved in the last years and allow earlier identification of bacterial strains in some cases, but these techniques are still quite expensive and not readily available in all institutions. Moreover, the ever increasing rates of resistance to antimicrobials, especially in Gram-negative pathogens, are threatening the outcome for such patients because of the lack of effective medical treatment; ICU physicians are therefore resorting to combination therapies to overcome resistance, with the direct consequence of promoting further resistance. A more appropriate use of available antimicrobials in the ICU should be pursued, and adjustments in doses and dosing through pharmacokinetics and pharmacodynamics have recently shown promising results in improving outcomes and reducing antimicrobial resistance. The aim of multidisciplinary antimicrobial stewardship programs is to improve antimicrobial prescription, and in this review we analyze the available experiences of such programs carried out in ICUs, with emphasis on results, challenges, and pitfalls. Any effective intervention aimed at improving antibiotic usage in ICUs must be brought about at the present time; otherwise, we will face the challenge of intractable infections in critically ill patients in the near future.

Abstract
OBJECTIVE to describe aminoglycoside use and nephrotoxicity in patients older than 75 years. DESIGN retrospective multicenter study. SETTING hospital department, rehabilitation, long-term care center. POPULATION patients ≥75 years old treated by aminoglycosides. RESULTS 184 patients, mean age: 84.4 years (range: 75-101). One hundred and twenty-seven patients received other nephrotoxic drug(s). Gentamicin (70%) and amikacin (30%) were used and the once-daily dosing was preferred (92%). Average treatment period was 2.75 (1-10) days for amikacin and 4.4 (1-30) for gentamicin with average dosage 13.5 and 3.5 mg/kg/day, respectively. The monitoring of maximal plasmatic concentration (Cmax) was done in 37 patients, 9 of them had probabilistic treatment. Only one had a Cmax fulfilling the objective of French recommendations (gentamicin >30 mg/l, amikacin >60 mg/l). When infection was documented, the objective of Cmax >10 × minimal inhibitory concentration of the strain was reached for 27%. Minimal plasmatic concentration was checked in 38% of cases, with adequate value (gentamicin <0.5 mg/l, amikacin <2.5 mg/l) for 37%. At the end of aminoglycoside course, 40 patients increased their serum creatinine >25% of the baseline value. In multivariate analysis, this was associated with treatment length ≥3 days and concomitant use of nephrotoxic drugs. CONCLUSION aminoglycosides dosing used in elderly patients probably need therapeutic drug monitoring and dose adjustment. Aminoglycosides are used to treat severe infections. One of the most important side effects is nephrotoxicity in oldest patients. To minimise nephrotoxicity, short treatments are necessary and avoiding others nephrotoxic drugs could be relevant.

Abstract
The case is described of a frail patient who developed prosthetic valve endocarditis due to methicillin-resistant Staphylococcus aureus (MRSA). Conventional antimicrobial treatments either failed or were contraindicated, and the patient was judged unsuitable for a further valve replacement. A salvage therapy with high doses of a new cephalosporin, ceftaroline, given three times daily was undertaken; subsequently, the patient had not relapsed at two months after completing a six-week course of ceftaroline. Ceftaroline deserves major attention as an alternative choice in difficult-to-treat MRSA endocarditis.
