A phase III randomized controlled trial of plitidepsin, a marine derived compound, in hospitalized adults with moderate COVID-19.

BACKGROUND: Plitidepsin has shown potent preclinical activity against SARS-CoV-2 and was generally well tolerated in a Phase I trial of hospitalized patients with COVID-19. NEPTUNO, a Phase III, multicenter, randomized, controlled trial, was designed to evaluate the efficacy and safety of plitidepsin in the management of moderate COVID-19 in hospitalized adult patients. METHODS: Included patients had documented SARS-CoV-2 infection, required oxygen therapy, and had adequate organ function. The planned sample size was 609 patients. Patients were randomized 1:1:1 to at least 3 days of dexamethasone plus either plitidepsin (1.5 mg/day or 2.5 mg/day, for 3 days) or standard of care (control). The primary endpoint was the time to sustained withdrawal of supplemental oxygen. Secondary endpoints included time to sustained hospital discharge, clinical status, duration of oxygen support, percentage of patients requiring admission to the intensive care unit, and safety. FINDINGS: After randomizing 205 patients, NEPTUNO was discontinued due to a notable drop in COVID-19-related hospitalizations. Available data suggest a 2-day improvement in the median time to sustained oxygen therapy discontinuation (5 vs 7 days) favoring both plitidepsin arms (hazard ratio [HR] 1.37, 95% confidence interval [CI] 0.96-1.96, p=0.08 for plitidepsin 1.5 mg vs control; HR 1.06, 95% CI 0.73-1.53, p=0.78 for plitidepsin 2.5 mg vs control). Plitidepsin was generally well tolerated. INTERPRETATION: Despite the trial limitations, these results suggest that plitidepsin may have a positive benefit-risk ratio in the management of patients requiring oxygen therapy. Further studies with plitidepsin, including those in immunosuppressed patients, are warranted. FUNDING: This trial has been funded by Pharmamar, S.A. (Madrid, Spain).

Prosthetic Joint Infections due to Candida Species: A Multicenter International Study.

BACKGROUND: Prosthetic joint infection (PJI) caused by Candida spp is a severe complication of arthroplasty. We investigated the outcomes of Candida PJI. METHODS: This was a retrospective observational multinational study including patients diagnosed with Candida-related PJI between 2010 and 2021. Treatment outcome was assessed at 2-year follow-up. RESULTS: A total of 269 patients were analyzed. Median age was 73.0 (interquartile range [IQR], 64.0-79.0) years; 46.5% of patients were male and 10.8% were immunosuppressed. Main infection sites were hip (53.0%) and knee (43.1%), and 33.8% patients had fistulas. Surgical procedures included debridement, antibiotics, and implant retention (DAIR) (35.7%), 1-stage exchange (28.3%), and 2-stage exchange (29.0%). Candida spp identified were Candida albicans (55.8%), Candida parapsilosis (29.4%), Candida glabrata (7.8%), and Candida tropicalis (5.6%). Coinfection with bacteria was found in 51.3% of cases. The primary antifungal agents prescribed were azoles (75.8%) and echinocandins (30.9%), administered for a median of 92.0 (IQR, 54.5-181.3) days. Cure was observed in 156 of 269 (58.0%) cases. Treatment failure was associated with age >70 years (OR, 1.811 [95% confidence interval {CI}: 1.079-3.072]), and the use of DAIR (OR, 1.946 [95% CI: 1.157-3.285]). Candida parapsilosis infection was associated with better outcome (OR, 0.546 [95% CI: .305-.958]). Cure rates were significantly different between DAIR versus 1-stage exchange (46.9% vs 67.1%, P = .008) and DAIR versus 2-stage exchange (46.9% vs 69.2%, P = .003), but there was no difference comparing 1- to 2-stage exchanges (P = .777). CONCLUSIONS: Candida PJI prognosis seems poor, with high rate of failure, which does not appear to be linked to immunosuppression, use of azoles, or treatment duration.

[Infectious endocarditis: strategy for diagnosis]. / Endocardites infectieuses : démarche diagnostique.

INFECTIOUS ENDOCARDITIS: STRATEGY FOR DIAGNOSIS. The diagnosis of infective endocarditis is often difficult because the clinical presentations are very heterogeneous. Epidemiology has evolved with more acute forms, different microorganisms, and an increase in prevalence in patients with cardiac prosthetic or electronic devices. Diagnosis is based on a clinical suspicion, associated with microbiological data and imaging evidence of lesions of the endocardium. Echocardiography plays a key role, but advanced imaging techniques provide additional information. The 2023 European Society of cardiology (ESC) recommendations like those of 2015 confirmed the essential role of multimodal imaging, integrating lesions highlighted by any imaging technique as major criteria. The diagnostic criteria have thus been modified to consider new epidemiological and imaging data. Different diagnostic strategy algorithms are proposed depending on whether the patient has prosthetic material or not. The endocarditis team is the keystone in this diagnostic approach to improve patient management.

ENDOCARDITES INFECTIEUSES: DÉMARCHE DIAGNOSTIQUE. Le diagnostic d'endocardite infectieuse est souvent difficile, car les présentations cliniques sont hétérogènes. L'épidémiologie a évolué avec des formes plus aiguës, des micro-organismes différents et avec l'augmentation de la prévalence chez les patients porteurs de matériel intracardiaque. Le diagnostic repose sur une suspicion clinique supportée par des données microbiologiques et la mise en évidence de lésions de l'endocarde à l'imagerie. L'échocardiographie joue un rôle clé, mais les techniques avancées d'imagerie permettent d'améliorer les performances diagnostiques. Les recommandations de l'European Society of Cardiology (ESC) 2023, comme celles de 2015, ont confirmé le rôle essentiel de l'imagerie multimodale, intégrant comme critères majeurs les lésions mises en évidence par toute technique d'imagerie. Les critères diagnostiques ont été ainsi modifiés pour prendre en compte les nouvelles données épidémiologiques et d'imagerie. Différents algorithmes de stratégie diagnostique sont proposés selon que le patient est porteur de matériel prothétique ou non. L'équipe multidisciplinaire d'endocardite est la clé de voûte dans cette démarche diagnostique pour améliorer la gestion des patients.

Impact of pharmacist-led interventions in a multidisciplinary consultation meeting for bone and joint infection.

INTRODUCTION: Management of bone and joint infections (BJI) requires prolonged and high-dose antibiotic therapy to achieve target concentrations in bone tissue. However, these therapies often lead to adverse effects in patients who are frequently fragile, with multiple comorbidities and associated medications. The decision to treat these complex cases is made during a multidisciplinary team meeting at the reference centre for complex osteoarticular infections (CRIOAC). MATERIAL AND METHODS: Elaborated by a pharmacist during CRIOAC meetings, a single-centre before-and-after comparative study of drug-related issues observed during pharmaceutical interventions (PIs), was conducted. For each patient included, a retrospective case was added. PIs were independently evaluated by a committee of infectiologists and pharmacists to assess their criticality. RESULTS: Sixty patients were included in the intervention group, with 59 controls. The population was homogeneous, with a median age of 65 years. Most BJI cases were complex (65.5 %), primarily involving prosthetic joint infections. Staphylococcus species were the predominant pathogens. Antibiotic therapy adapted to antibiograms was orally relayed for 74 % of patients, with 5.9 % requiring re-hospitalization due to adverse effects. Sixty-two PIs were performed, representing an average of 1.8 PIs per meeting or 34.4 % of patients. Dosage adjustment accounted for 42 % of PIs, drug interactions for 46 %, and treatment availability in community pharmacies for 8 %. Regarding criticality, three PIs were classified as vital, 22 as major, 22 as moderate, and 15 as minor in both groups, with the same distribution between the intervention and control groups. CONCLUSION: This study demonstrates that by collaborating with surgeons and infectiologists, pharmacists participating in CRIOAC meetings can strongly help to prevent drug-related problems in patients with BJIs.

Severe enterovirus infections in patients with immune-mediated inflammatory diseases receiving anti-CD20 monoclonal antibodies.

OBJECTIVE: Patients with X linked agammaglobulinemia are susceptible to enterovirus (EV) infections. Similarly, severe EV infections have been described in patients with impaired B-cell response following treatment with anti-CD20 monoclonal antibodies (mAbs), mostly in those treated for haematological malignancies. We aimed to describe severe EV infections in patients receiving anti-CD20 mAbs for immune-mediated inflammatory diseases (IMIDs). METHODS: Patients were included following a screening of data collected through the routine surveillance of EV infections coordinated by the National Reference Center and a review of the literature. Additionally, neutralising antibodies were assessed in a patient with chronic EV-A71 meningoencephalitis. RESULTS: Nine original and 17 previously published cases were retrieved. Meningoencephalitis (n=21/26, 81%) associated with EV-positive cerebrospinal fluid (n=20/22, 91%) was the most common manifestation. The mortality rate was high (27%). EV was the only causal agents in all reported cases. Patients received multiple anti-CD20 mAbs infusions (median 8 (5-10)), resulting in complete B-cell depletion and moderate hypogammaglobulinemia (median 4.9 g/L (4.3-6.7)), and had limited concomitant immunosuppressive treatments. Finally, in a patient with EV-A71 meningoencephalitis, a lack of B-cell response to EV was shown. CONCLUSION: EV infection should be evoked in patients with IMIDs presenting with atypical organ involvement, especially meningoencephalitis. Anti-CD20 mAbs may lead to impaired B-cell response against EV, although an underlying primary immunodeficiency should systematically be discussed.

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.

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.

Mpox in people with past infection or a complete vaccination course: a global case series.

BACKGROUND: Since May, 2022, a large global outbreak of human mpox (formerly known as monkeypox) has predominantly affected men who have sex with men. The strain responsible, Clade IIb, has mutated substantially from precursors originating from the 2017-18 outbreak in Nigeria. Immunity to smallpox, another orthopoxvirus, via previous infection or vaccination provides lifelong immunity. However, since the 2022 mpox outbreak, recent clusters were described in individuals with presumed immunity through recent infection or vaccination. We aim to describe the epidemiological and clinical characteristics of mpox in individuals with past infection or vaccination to improve the understanding of this disease in the setting of previous immunity. METHODS: In this global case series, international collaborators from nine countries provided data on individuals with PCR-confirmed mpox after documented previous infection or vaccination between May 11, 2022, and June 30, 2023. We excluded cases that could not confirm vaccination status or cases with partial immunisation or any doses received before the current multi-national mpox outbreak (cutoff date May 1, 2022). Data were collected via a case report spreadsheet that reported on dates of infection and vaccination, route of immunisation, demographic characteristics, clinical findings, HIV status, concomitant sexually transmitted infections, and markers of disease severity (mpox severity score system). We describe case epidemiology, clinical course, and mpox severity scores; all analyses were descriptive. FINDINGS: We report mpox infections in 37 gay and bisexual men who have sex with men: seven individuals had mpox reinfections, 29 individuals had mpox infections that occurred after two appropriately spaced Modified Vaccinia Ankara-Bavarian Nordic vaccine courses, and one individual had an infection that met the criteria for both reinfection and infection after vaccination. The median age of individuals was 36 years (IQR 30-45; range 21-58). Those with natural immunity after initial infection had a shorter disease course with less mucosal disease upon reinfection than with their initial infection. Infections post-vaccination were characterised by few lesions, little mucosal disease, and minimal analgesia requirements; two people received oral tecovirimat. Overall, there were no deaths, no bacterial superinfections, and all individuals were managed in the ambulatory clinic with one hospital admission for a necrotising neck lesion. INTERPRETATION: The epidemiology of people with mpox reinfection or infection post-vaccination was similar to other published cohorts during the 2022 outbreak-predominantly young, sexually active gay and bisexual men who have sex with men. Clinical features and outcomes of repeat infection and infection after vaccination appear to be less clinically severe than those described in 2022 case literature. Specifically, compared with the 2022 case series, these individuals in the present study had fewer confluent lesions, less mucosal involvement, reduced analgesia requirement, and fewer admissions. Natural immunity and vaccine-induced immunity are not fully protective against mpox infection. However, in this small series both disease duration and severity appear to be reduced. FUNDING: None.

Impact of influenza immunity on the mortality among older adults hospitalized with COVID-19: a retrospective cohort study.

It has been suggested that the outcomes of coronavirus disease 2019 (COVID-19) are better in individuals having recently received an influenza vaccine than in non-vaccinated individuals. We hypothesized that this association depends on the humoral responses against influenza viruses. We aim to assess the relationship between the humoral immunity against influenza and the 3-month all-cause mortality among hospitalized older patients with COVID-19. We performed an exploratory retrospective study of older patients (aged 65 and over) hospitalized for confirmed COVID-19 between November 2020 and June 2021. Previous humoral responses to influenza viruses were assessed using a hemagglutination inhibition assay on routinely collected blood samples. The study's primary outcome was the 3-month all-cause mortality, and the secondary outcomes were severe COVID-19 (oxygen requirement ≥ 6 L/min or ventilatory support) and complications (kidney or heart failure, thrombosis and bacterial infection). In the cohort of 95 patients with COVID-19, immunity against influenza vaccine subtypes/lineages was not significantly associated with 3-month all-cause mortality, with an OR [95%CI] of 0.22 [0.02-1.95] (p = 0.174) for the H1N1pdm09 subtype, 0.21 [0.03-1.24] (p = 0.081) for A/Hong Kong/2671/2019 H3N2 subtype, 1.98 [0.51-8.24] (p = 0.329) for the B/Victoria lineage, and 1.82 [0.40-8.45] (p = 0.437) for the B/Yamagata lineage. Immunity against influenza vaccine subtypes/lineages was also not significantly associated with severity and complication. Immunity against influenza subtypes/lineages included in the 2020-2021 vaccine was not associated with a lower 3-month all-cause mortality among COVID-19 hospitalized patients.Trial registration: The study was approved by a hospital committee with competency for research not requiring approval by an institutional review board (Tours University Medical Center, Tours, France: reference: 2021_015). All patients give the informed consent.

Non-HACEK gram-negative bacilli endocarditis: a multicentre retrospective case-control study.

BACKGROUND: Infective endocarditis (IE) caused by non-HACEK gram-negative bacilli (GNB) is poorly characterised and may be emerging as a consequence of medical progress. METHODS: We performed an observational retrospective case-control study. Cases were non-HACEK GNB IE, definite or possible (modified Duke criteria), diagnosed in adults between 2007 and 2020 in six French referral hospitals. Two controls were included for each case (IE due to other bacteria, matched by sites and diagnosis date). RESULTS: Non-HACEK GNB were identified in 2.4% (77/3230) of all IE during the study period, with a mean age of 69.2 ± 14.6 years, and a large male predominance (53/77, 69%). Primary pathogens were Escherichia coli (n = 33), Klebsiella sp. (n = 12) and Serratia marcescens (n = 9), including eight (10%) multidrug-resistant GNB. Compared to controls (n = 154: 43% Streptococcus sp., 41% Staphylococcus sp. and 12% Enterococcus sp.), non-HACEK GNB IE were independently associated with intravenous drug use (IVDU, 8% vs. 2%, p = .003), active neoplasia (15% vs. 6%, p = .009), haemodialysis (9% vs. 3%, p = .007) and healthcare-associated IE (36% vs. 18%, p = .002). Urinary tract was the main source of infection (n = 25, 33%) and recent invasive procedures were reported in 29% of cases. Non-HACEK GNB IE were at lower risk of embolism (31% vs. 47%, p = .002). One-year mortality was high (n = 28, 36%). Comorbidities, particularly malignant hemopathy and cirrhosis, were associated with increased risk of death. CONCLUSIONS: Non-HACEK GNB are rarely responsible for IE, mostly as healthcare-associated IE in patients with complex comorbidities (end-stage renal disease, neoplasia), or in IVDUs.

Clinical, Bacteriological, and Genetic Characterization of Bone and Joint Infections Involving Linezolid-Resistant Staphylococcus epidermidis: a Retrospective Multicenter Study in French Reference Centers.

The choice of the best probabilistic postoperative antibiotics in bone and joint infections (BJIs) is still challenging. Since the implementation of protocolized postoperative linezolid in six French referral centers, linezolid-resistant multidrug-resistant Staphylococcus epidermidis (LR-MDRSE) strains were isolated in patients with BJI. We aimed here to describe clinical, microbiological, and molecular patterns associated with these strains. All patients with at least one intraoperative specimen positive for LR-MDRSE between 2015 and 2020 were included in this retrospective multicenter study. Clinical presentation, management, and outcome were described. LR-MDRSE strains were investigated by MIC determination for linezolid and other anti-MRSA antibiotics, characterization of genetic determinants of resistance, and phylogenetic analysis. Forty-six patients (colonization n = 10, infection n = 36) were included in five centers, 45 had prior exposure to linezolid, 33 had foreign devices. Clinical success was achieved for 26/36 patients. Incidence of LR-MDRSE increased over the study period. One hundred percent of the strains were resistant to oxazolidinones, gentamicin, clindamycin, ofloxacin, rifampicin, ceftaroline, and ceftobiprole, and susceptible to cyclins, daptomycin, and dalbavancin. Susceptibility to delafloxacin was bimodal. Molecular analysis was performed for 44 strains, and the main mutation conferring linezolid resistance was the 23S rRNA G2576T mutation. All strains belonged to the sequence type ST2 or its clonal complex, and phylogenetic analysis showed emergence of five populations corresponding geographically to the centers. We showed the emergence of new clonal populations of highly linezolid-resistant S. epidermidis in BJIs. Identifying patients at risk for LR-MDRSE acquisition and proposing alternatives to systematic postoperative linezolid use are essential. IMPORTANCE The manuscript describes the emergence of clonal linezolid-resistant strains of Staphylococcus epidermidis (LR-MDRSE) isolated from patients presenting with bone and joint infections. Incidence of LR-MDRSE increased over the study period. All strains were highly resistant to oxazolidinones, gentamicin, clindamycin, ofloxacin, rifampicin, ceftaroline, and ceftobiprole, but were susceptible to cyclins, daptomycin, and dalbavancin. Susceptibility to delafloxacin was bimodal. The main mutation conferring linezolid resistance was the 23S rRNA G2576T mutation. All strains belonged to the sequence type ST2 or its clonal complex, and phylogenetic analysis showed emergence of five populations corresponding geographically to the centers. LR-MDRSE bone and joint infections seem to be accompanied by an overall poor prognosis related to comorbidities and therapeutic issues. Identifying patients at risk for LR-MDRSE acquisition and proposing alternatives to systematic postoperative linezolid use become essential, with a preference for parenteral drugs such as lipopeptids or lipoglycopeptids.

Amoxicillin therapeutic drug monitoring for endocarditis: A comparative study (EI-STAB).

INTRODUCTION: International guidelines recommend high doses of ß-lactams for most cases of infective endocarditis (IE). Therapeutic drug monitoring (TDM) is increasingly used to adjust ß-lactam dose based on plasma concentrations, although there are no comparative studies to support this practice. The benefit of amoxicillin TDM during IE was evaluated. METHODS: An observational, retrospective, cohort study of adults treated with high-dose amoxicillin for enterococcal or streptococcal IE was conducted in two referral centers. Patients with, or without TDM were compared. The primary outcome was mean daily amoxicillin dose. RESULTS: A total of 206 cases of streptococcal (n=140, 68%) or enterococcal (n=66, 32%) IE were included. IE occurred on prosthetic valves in 77 (37%) cases, and on intracardiac devices in 28 (14%) cases. Aortic valve was involved in 136 (66%) cases. There were 154 men (75%), mean age was 70 ± 14 years, valve surgery was performed in 81/206 (39%) patients, and in-hospital mortality was 8% (17/206). All patients in the TDM group and most patients in the group without TDM received amoxicillin as continuous infusion. Amoxicillin TDM was performed for 114 patients (55.3%), with a mean of 4.7 ± 2.3 measures per patient, a mean plasma steady-state concentration of 41.2 ± 19 mg/L, most (82/114, 72%) being within the therapeutic target (20-80 mg/L). Mean amoxicillin dose was lower in patients with TDM (10.0 ± 3.3 g/day) than those without TDM (11.3 ± 2.0 g/day) (P=0.003). CONCLUSION: Amoxicillin TDM was associated with a reduction in daily doses, with no impact on adverse events and prognosis. Individualized treatment of IE through TDM may contribute to decreased use of antibiotics.

Multicenter Retrospective Study of Vascular Infections and Endocarditis Caused by Campylobacter spp., France.

The incidence of campylobacteriosis has substantially increased over the past decade, notably in France. Secondary localizations complicating invasive infections are poorly described. We aimed to describe vascular infection or endocarditis caused by Campylobacter spp. We included 57 patients from a nationwide 5-year retrospective study on Campylobacter spp. bacteremia conducted in France; 44 patients had vascular infections, 12 had endocarditis, and 1 had both conditions. Campylobacter fetus was the most frequently involved species (83%). Antibiotic treatment involved a ß-lactam monotherapy (54%) or was combined with a fluoroquinolone or an aminoglycoside (44%). The mortality rate was 25%. Relapse occurred in 8% of cases and was associated with delayed initiation of an efficient antimicrobial therapy after the first symptoms, diabetes, and coexistence of an osteoarticular location. Cardiovascular Campylobacter spp. infections are associated with a high mortality rate. Systematically searching for those localizations in cases of C. fetus bacteremia may be warranted.

Impact of Enterococcus faecalis Endocarditis Treatment on Risk of Relapse.

BACKGROUND: Enterococcus faecalis infective endocarditis (EFIE) is characterized by a higher frequency of relapses than other infective endocarditis. The role of the treatment on its occurrence remains poorly understood. The aim of this study was to investigate whether the antibiotic regimen could impact the risk of relapse in EFIE. MATERIALS: This was a multicenter retrospective study of patients diagnosed with definite EFIE between 2015 and 2019 in 14 French hospitals. The primary endpoint was the occurrence of relapses within the year following endocarditis diagnosis. As death was a competing risk for relapse, Fine and Gray models were used for studying risk factors and impact of treatment. RESULTS: Of the 279 patients included, 83 (29.7%) received the amoxicillin-gentamicin (A-G) combination, 114 (40.9%) amoxicillin-ceftriaxone (A-C), 63 (22.6%) A-G and A-C (A-G/A-C) sequentially, 9 (3.2%) amoxicillin (A), and 10 received other treatments. One-year-relapse rate was 9.3% (26 patients). Relapse occurred after a median delay of 107 days from EFIE diagnosis; 6 occurred after 6 months, and 6 were diagnosed by blood cultures in asymptomatic patients. In multivariate analysis, surgery during treatment was a protective factor against one-year relapse and death.The cumulative incidence of relapse 1 year after endocarditis was 46.2% for patients treated with amoxicillin, 13.4% with A-G, 14.7% with A-C, and 4.3% with A-G/A-C (P≥.05 in multivariate analysis). CONCLUSIONS: Relapses after treatment of EFIE are frequent, frequently asymptomatic, and may occur more than 6 months after the initial episode.

Inter-expert agreement on indications for antibiotic therapy in older adults admitted to French hospital through an emergency department.

Background: Around one third of older adults with infections have an atypical presentation upon admission to an emergency department (ED). Objective: To evaluate the level of agreement between experts from several disciplines on the indication for antibiotic therapy for a bacterial infection in older patients presenting at an ED, and to describe the characteristics of the infections. Methods: Based on comprehensive medical records, three experts (a geriatrician, an emergency physician (EP), and an infectious disease specialist (IDS)) determined independently and then jointly whether a patient presenting at the ED had a bacterial infection requiring antibiotic therapy. Inter-expert agreement was expressed as a fixed-marginal Fleiss' kappa (κ). Results: Of the 444 medical records included, the consensus meeting found that 114 (25.7%) had an indication for antibiotics, 327 (73.6%) did not have an indication, and 3 could not be classified. The overall level of agreement was 85.2%, and κ[95%CI] was 0.64 [0.57-0.72] (p < 0.001). The level of agreement between the geriatrician and the IDS (89.41%, κ0.73, 95%CI [0.62-0.85] (p < 0.001)) was higher than that between the geriatrician and the EP (83.56%, κ0.62, 95%CI [0.51-0.73] (p < 0.001)) and between the IDS and the EP (82.66%, κ0.59, 95%CI [0.48-0.70] (p < 0.001)). The levels of agreement between the final adjudication, was higher for the geriatrician, and IDS respectively 94.1% (κ0.85, 95%CI [0.74-0.97] (p < 0.001) and 94.4% (κ0.86, 95%CI [0.74-0.97] (p < 0.001)). 114 (25.7%) patients had a bacterial infection (mostly lung infections (n = 55, 48.2%) and urinary tract infections (n = 25, 21.9%)), and 28 patients (6.3%) had a viral infection. Conclusion: Our results highlighted substantial agreement between members of a multidisciplinary expert panel.

Chronic subcutaneous infection of Purpureocillium lilacinum in an immunocompromised patient: Case report and review of the literature.

Our case reports a 52-year-old woman who presented with Purpureocillium lilacinum skin infection after a renal transplantation. The diagnosis was difficult and this species exhibits many resistances to antifungal agents. The clinical history was marked by a relapse causes by a foreign body. Our case suggests that posaconazole may be an alternative to cure P. lilacinum infection, and that the surgical debridement, the identification and removal of a foreign body may improve the prognosis.

When to investigate for secondary hyperhidrosis: data from a retrospective cohort of all causes of recurrent sweating.

Background: Identification of underlying diseases is crucial for secondary hyperhidrosis management, but data are lacking to guide appropriate investigation.Objective: To describe aetiologies of recurrent sweating in a hospital setting and the diagnostic performance parameters of their respective clinical/biological features.Patients and Methods: We performed a monocentric evaluative study in a tertiary care centre. Patients with recurrent generalised sweating were selected via the Clinical Data Warehouse (CDW) by screening all electronic hospital documents from the year 2018 using a keyword-based algorithm. All in and out-patients aged ≥ 18 years having reported recurrent sweating for at least 2 weeks in 2018 were included, with a minimum one-year follow-up after symptoms' onset.Results: A total of 420 patients were included. Over 130 different aetiologies were identified; 70 patients (16.7%) remained without diagnosis. Solid organ cancers (14.3% with 13 lung cancers), haematologic malignancies (14.0% with 35 non-Hodgkin's lymphomas) and Infectious Diseases (10.5% including 13 tuberculosis) were the most frequent diagnoses. Other aetiologies were gathered into inflammatory (16.9%) and non-inflammatory (27.6%) conditions. To distinguish non-inflammatory and undiagnosed hyperhidrosis from other causes, fever had a specificity of 94%, impaired general condition a sensitivity of 78%, and C-reactive protein (CRP) > 5.6 mg/l a positive predictive value of 0.86. Symptoms' duration over 1 year was in favour of non-infectious and non-malignant causes (94% specificity).Conclusions: We identified fever, impaired general condition, duration, and CRP as helpful orientation parameters to assess the need for complementary explorations for hyperhidrosis. The study provides a diagnostic algorithm for the investigation of recurrent sweating.KEY MESSAGESIn a hospital setting, malignancies and infections are the most frequently associated diseases, but 1/5 remain without diagnosis.Fever is a specific but not sensitive sign to distinguish inflammatory conditions.Over 1 year duration of symptoms significantly reduce the probability of malignancy or infection as the underlying diagnosis.
