Compared Performance of the 2023 Duke-International Society for Cardiovascular Infectious Diseases, 2000 Modified Duke, and 2015 European Society of Cardiology Criteria for the Diagnosis of Infective Endocarditis in a French Multicenter Prospective Cohort.

BACKGROUND: The 2023 Duke-International Society for Cardiovascular Diseases (ISCVID) criteria for infective endocarditis (IE) were proposed as an updated diagnostic classification of IE. Using an open prospective multicenter cohort of patients treated for IE, we compared the performance of these new criteria to that of the 2000 Modified Duke and 2015 European Society of Cardiology (ESC) criteria. METHODS: Cases of patients treated for IE between January 2017 and October 2022 were adjudicated as certain IE or not. Each case was also categorized as either definite or possible/rejected within each classification. Sensitivity, specificity, and accuracy were estimated with 95% confidence intervals. RESULTS: Of the 1194 patients analyzed (mean age, 66.1 years; 71.2% males), 414 (34.7%) had a prosthetic valve and 284 (23.8%) had a cardiac implanted electronic device (CIED); 946 (79.2%) were adjudicated as certain IE; 978 (81.9%), 997 (83.5%), and 1057 (88.5%) were classified as definite IE in the 2000 modified Duke, 2015 ESC, and 2023 Duke-ISCVID criteria, respectively. The sensitivity of each set of criteria was 93.2% (95% confidence interval [CI], 91.6-94.8), 95.0% (95% CI, 93.7-96.4), and 97.6% (95% CI, 96.6-98.6), respectively (P < .001 for all 2-by-2 comparisons). Corresponding specificity rates were 61.3% (95% CI, 55.2-67.4), 60.5% (95% CI, 54.4-66.6), and 46.0% (95% CI, 39.8-52.2), respectively. In patients without CIED, sensitivity rates were 94.8% (95% CI, 93.2-96.4), 96.5% (95% CI, 95.1-97.8), and 97.7% (95% CI, 96.6-98.8); specificity rates were 59.0% (95% CI, 51.6-66.3), 56.6% (95% CI, 49.3-64.0), and 53.8% (95% CI, 46.3-61.2), respectively. CONCLUSIONS: Overall, the 2023 Duke-ISCVID criteria had a significantly higher sensitivity but a significantly lower specificity compared with older criteria. This decreased specificity was mainly attributable to patients with CIED.

Therapeutic failures of targeted antibiotic prophylaxis in urology.

Targeted antibiotic prophylaxis (TAP) is required for patients with positive urine culture before urological surgery. Our aim was to determine the efficacy of TAP. This was a prospective single-center study performed in a urology department. All patients who underwent a programmed surgery were included. Urine culture was obtained before surgery requiring a prophylaxis: in the case of sterile urines, antibiotics were used in accordance with national recommendations; for positive urine culture, a TAP was used in accordance with susceptibility testing. The drugs were administered for 2 days before surgery until withdrawal of bladder catheter. The occurrence of healthcare-associated infections was registered until day 30 after surgery. Two hundred three patients were included for 8 non-consecutive weeks in 2020, among whom fifteen were lost of sight before day 30. Among the remaining 188 patients, most frequent surgeries were 75 prostatic diseases (40%), 50 endo-ureteral surgeries for JJ stent insertion (27%), and 23 bladder cancers (12%). One hundred forty-eight (79%) patients required a urine culture before procedure; 142/148 (96%) urine cultures were performed, leading to 74 TAP. The main isolated bacteria were 48 Enterobacteriaceae and 8 Enterococcus spp. TAP was cotrimoxazole (n = 30), aminoglycosides (n = 11), amoxicillin (n = 9), fluoroquinolones (n = 7), and others (n = 17). The rate of healthcare-associated infections was 14.8% (11/74), including six microbiologically documented antibiotic failures. The rate of healthcare-associated infection after urological surgery using TAP was high, implying to discuss the choice and the dosage of the antibiotic molecules.

Severe Thrombocytopenia after Zika Virus Infection, Guadeloupe, 2016.

Severe thrombocytopenia during or after the course of Zika virus infection has been rarely reported. We report 7 cases of severe thrombocytopenia and hemorrhagic signs and symptoms in Guadeloupe after infection with this virus. Clinical course and laboratory findings strongly suggest a causal link between Zika virus infection and immune-mediated thrombocytopenia.

Severe Sepsis and Septic Shock Associated with Chikungunya Virus Infection, Guadeloupe, 2014.

During a 2014 outbreak, 450 patients with confirmed chikungunya virus infection were admitted to the University Hospital of Pointe-à-Pitre, Guadeloupe. Of these, 110 were nonpregnant adults; 42 had severe disease, and of those, 25 had severe sepsis or septic shock and 12 died. Severe sepsis may be a rare complication of chikungunya virus infection.

The impact of transoesophageal echocardiography in elderly patients with infective endocarditis.

BACKGROUND: Infective endocarditis (IE) increasingly involves older patients. Geriatric status may influence diagnostic and therapeutic decisions. AIM: To describe transoesophageal echocardiography (TEE) use in elderly IE patients, and its impact on therapeutic management and mortality. METHODS: A multicentre prospective observational study (ELDERL-IE) included 120 patients aged ≥75 years with definite or possible IE: mean age 83.1±5.0; range 75-101 years; 56 females (46.7%). Patients had an initial comprehensive geriatric assessment, and 3-month and 1-year follow-up. Comparisons were made between patients who did or did not undergo TEE. RESULTS: Transthoracic echocardiography revealed IE-related abnormalities in 85 patients (70.8%). Only 77 patients (64.2%) had TEE. Patients without TEE were older (85.4±6.0 vs. 81.9±3.9 years; P=0.0011), had more comorbidities (Cumulative Illness Rating Scale-Geriatric score 17.9±7.8 vs. 12.8±6.7; P=0.0005), more often had no history of valvular disease (60.5% vs. 37.7%; P=0.0363), had a trend toward a higher Staphylococcus aureus infection rate (34.9% vs. 22.1%; P=0.13) and less often an abscess (4.7% vs. 22.1%; P=0.0122). Regarding the comprehensive geriatric assessment, patients without TEE had poorer functional, nutritional and cognitive statuses. Surgery was performed in 19 (15.8%) patients, all with TEE, was theoretically indicated but not performed in 15 (19.5%) patients with and 6 (14.0%) without TEE, and was not indicated in 43 (55.8%) patients with and 37 (86.0%) without TEE (P=0.0006). Mortality was significantly higher in patients without TEE. CONCLUSIONS: Despite similar IE features, surgical indication was less frequently recognized in patients without TEE, who less often had surgery and had a poorer prognosis. Cardiac lesions might have been underdiagnosed in the absence of TEE, hampering optimal therapeutic management. Advice of geriatricians should help cardiologists to better use TEE in elderly patients with suspected IE.

Risk factors of long term symptoms and outcomes among patients discharged after covid-19: prospective, multicentre observational study.

Objective: To investigate risk factors and subphenotypes associated with long term symptoms and outcomes after hospital admission for covid-19. Design: Prospective, multicentre observational study. Setting: 93 hospitals in France. Participants: Data from 2187 adults admitted to hospital with covid-19 in France between 1 February 2020 and 30 June 2021. Main outcome measures: Primary endpoint was the total number of persistent symptoms at six months after hospital admission that were not present before admission. Outcomes examined at six months were persistent symptoms, Hospital Anxiety and Depression Scale, six minute walk test distances, 36-Item Short Form Health Survey scores, and ability to resume previous professional activities and self-care. Secondary endpoints included vital status at six months, and results of standardised quality-of-life scores. Additionally, an unsupervised consensus clustering algorithm was used to identify subphenotypes based on the severity of hospital course received by patients. Results: 1109 (50.7%) of 2187 participants had at least one persistent symptom. Factors associated with an increased number of persistent symptoms were in-hospital supplemental oxygen (odds ratio 1.12, 95% confidence interval 1 to 1.24), no intensive care unit admission (1.15, 1.01 to 1.32), female sex (1.33, 1.22 to 1.45), gastrointestinal haemorrhage (1.51, 1.02 to 2.23), a thromboembolic event (1.66, 1.17 to 2.34), and congestive heart failure (1.76, 1.27 to 2.43). Three subphenotypes were identified: including patients with the least severe hospital course (based on ventilatory support requirements). Although Hospital Anxiety and Depression Scale scores were within normal values for all groups, patients of intermediate severity and more comorbidities had a higher median Hospital Anxiety and Depression Scale score than did the other subphenotypes. Patients in the subphenotype with most severe hospital course had worse short form-36 scores and were less able to resume their professional activity or care for themselves as before compared with other subphenotypes. Conclusions: Persistent symptoms after hospital admission were frequent, regardless of acute covid-19 severity. However, patients in more severe subphenotypes had a significantly worse functional status and were less likely to resume their professional activity or able to take care of themselves as before.

Seroprevalence of chikungunya virus infection among HIV-infected adults in French Caribbean Islands of Martinique and Guadeloupe in 2015: A cross-sectional study.

BACKGROUND: In 2014, a first outbreak of chikungunya hit the Caribbean area where chikungunya virus (CHIKV) had never circulated before. METHODOLOGY/PRINCIPAL FINDINGS: We conducted a cross-sectional study to measure the seroprevalence of CHIKV immediately after the end of the 2014 outbreak in HIV-infected people followed up in two clinical cohorts at the University hospitals of Guadeloupe and Martinique. Study patients were identified during the first months of 2015 and randomly selected to match the age and sex distribution of the general population in the two islands. They were invited to complete a survey that explored the symptoms consistent with chikungunya they could have developed during 2014 and to have a blood sample drawn for CHIKV serology. The study population consisted of 377 patients (198 in Martinique and 179 in Guadeloupe, 178 men and 199 women), 182 of whom reported they had developed symptoms consistent with chikungunya. CHIKV serology was positive in 230 patients, which accounted for an overall seroprevalence rate of 61% [95%CI 56-66], with only 153 patients who reported symptoms consistent with chikungunya. Most frequent symptoms included arthralgia (94.1%), fever (73.2%), myalgia (53.6%), headache (45.8%), and skin rash (26.1%). CONCLUSIONS/SIGNIFICANCE: This study showed that the seroprevalence of CHIKV infection was 61% after the 2014 outbreak, with one third of asymptomatic infections. TRIAL REGISTRATION: ClinicalTrials.gov NCT02553369.

Relationships between sex, early valve surgery and mortality in patients with left-sided infective endocarditis analysed in a population-based cohort study.

OBJECTIVE: Whether sex-related differences in the prognosis of infective endocarditis (IE) are due to differences in disease severity or comorbid patterns, physiological specificities or a treatment indication bias is unclear. We conducted an analysis of the pooled database of two population-based cohorts of IE to reassess the relationships between sex, early valve surgery (EVS) and outcome in patients with IE. METHODS: Demographic and baseline characteristics, complications and outcome were compared in men and women with Duke-definite left-sided IE. A propensity model for EVS was constructed using multivariate logistic regression. Factors associated with 1-year mortality were identified using multivariate Cox models adjusted for EVS factors. RESULTS: The study population included 466 (75%) men and 154 (25%) women. Compared with men, women were older (p=0.005), were more often on haemodialysis (p=0.04), more often had a mitral valve IE (50.0% vs 35.8%, p=0.02), less often developed a septic shock (p=0.05), less often underwent EVS (p=0.001) yet had comparable inhospital mortality rates (20.1% vs 20.0%, p=0.96) and similar 1-year survival probability (logrank p=0.68). Female sex was neither associated with EVS (OR 0.76 (95% CI 0.49 to 1.16)) nor mortality (HR 1.17 (95% CI 0.80 to 1.69)). However EVS was associated with an increased risk of death in women in the early postoperative period (HR 8.72 (95% CI 3.42 to 22.24), p=<0.0001). CONCLUSIONS: Women underwent EVS less often than men. However female sex was independently associated with neither EVS nor 1-year mortality. The reasons for a higher risk of early postoperative mortality in women must still be elucidated.
