RESUMEN
BACKGROUND: Despite the burden of pyelonephritis after kidney transplantation, there is no consensus on initial empirical antibiotic management. METHODS: We surveyed clinicians throughout the world on their practice and opinions about the initial empirical therapy of post-transplant pyelonephritis, using clinical vignettes. A panel of experts from 19 countries on six continents designed this survey, and invited 2145 clinicians to participate. RESULTS: A total of 721 clinicians completed the survey (response rate: 34%). In the hypothetical case of a kidney transplant recipient admitted with pyelonephritis but not requiring intensive care, most respondents reported initiating either a 3rd-generation cephalosporin (37%) or piperacillin-tazobactam (21%) monotherapy. Several patient-level factors dictated the selection of broader-spectrum antibiotics, including having a recent urine culture showing growth of a resistant organism (85% for extended-spectrum ß-lactamase-producing organisms, 90% for carbapenemase-producing organisms, and 94% for Pseudomonas aeruginosa). Respondents attributed high importance to the appropriateness of empirical therapy, which 87% judged important to prevent mortality. Significant practice and opinion variations were observed between and within countries. CONCLUSION: High-quality studies are needed to guide the empirical management of post-transplant pyelonephritis. In particular, whether prior urine culture results should systematically be reviewed and considered remains to be determined. Studies are also needed to clarify the relationship between the appropriateness of initial empirical therapy and outcomes of post-transplant pyelonephritis.

OBJECTIVES: Here, we report the management of a catastrophic COVID-19 Delta variant surge, which overloaded ICU capacity, using crisis standards of care (CSC) based on a multiapproach protocol. DESIGN: Retrospective observational study. SETTING: University Hospital of Guadeloupe. PATIENTS: This study retrospectively included all patients who were hospitalized for COVID-19 pneumonia between August 11, 2021, and September 10, 2021, and were eligible for ICU admission. INTERVENTION: Based on age, comorbidities, and disease severity, patients were assigned to three groups: Green (ICU admission as soon as possible), Orange (ICU admission after the admission of all patients in the Green group), and Red (no ICU admission). MEASUREMENTS AND MAIN RESULTS: Among the 328 patients eligible for ICU admission, 100 (30%) were assigned to the Green group, 116 (35%) to the Orange group, and 112 (34%) to the Red group. No patient in the Green group died while waiting for an ICU bed, whereas 14 patients (12%) in the Orange group died while waiting for an ICU bed. The 90-day mortality rates were 24%, 37%, and 78% in the Green, Orange, and Red groups, respectively. A total of 130 patients were transferred to the ICU, including 79 from the Green group, 51 from the Orange group, and none from the Red group. Multivariate analysis revealed that among patients admitted to the ICU, death was independently associated with a longer time between ICU referral and ICU admission, the Sequential Organ Failure Assessment score, and the number of comorbidities, but not with triage group. CONCLUSIONS: CSC based on a multiapproach protocol allowed admission of all patients with a good prognosis. Higher mortality was associated with late admission, rather than triage group.

OBJECTIVES: We aimed to determine the impact of a dedicated medical team (DMT) on ambulatory care for patients requiring oxygen. METHODS: The DMT selected patients requiring oxygen for less than 5 l/min in the emergency department (ED). The rate of ED readmission was compared in patients managed by the DMT and those managed by the ED physicians (EDPs). Consensual treatment for COVID-19 pneumonia with oxygen requirement was steroids + preventive anticoagulation. RESULTS: A total of 1397 patients with COVID-19 came to our ED from the first to the 31st of August, 2021, among whom 580 (41%) had ambulatory care. A total of 82 (14.1%) patients were managed by the DMT, with a rate of ED readmission of 4.8% (4/82), compared with 13.6% (68/498) for those managed by EDPs (P <0.001). Focusing on the 45/498 (9.0%) patients requiring oxygen and managed by EDPs, the rate of ED readmission was 20%, P = 0.017. Prescription of the consensual treatment concerned 96% versus 40% for those patients requiring oxygen for the DMT and the EDP, respectively (P <0.001). CONCLUSION: A DMT for ambulatory care of patients with COVID-19 requiring oxygen was associated with less return to the ED than usual practices.

Only limited real-life data are available on the effects of neutralizing monoclonal antibodies in high-risk patients who have early COVID-19 and do not require supplemental oxygen. We prospectively studied 217 patients infected by the delta variant who received casirivimab plus indevimab in a dedicated ambulatory unit created during our 4th COVID wave. Mean age was 64 years, 94% had at least one comorbidity, and mean duration of symptoms was 2.9 days. Oxygen requirement, hospitalization, and mortality rates were 10, 6, and 2.8%, respectively. These results suggest benefits of early administration of neutralizing antibodies in high-risk patients infected with the delta variant.

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.

Toxic Shock Syndrome (TSS) is a very rare and severe complication of Staphylococcus aureus infections. However, bacteremia is very uncommon in this disease. We present here the case of a healthy 15-year old boy who presented septic shock and diffuse exanthema four hours after eating in a fast food restaurant. Blood cultures were positive for a TSST-1 producing Staphylococcus aureus. The patient was treated with antibiotics and fully recovered.
RESUMEN
The serological prevalence of Epstein-Barr virus (EBV) among young adults exceeds 90% worldwide. Even though EBV primary infection is usually benign, severe complications can occur in adolescents and young adults and so the disease must be promptly diagnosed. The development of an oropharyngeal abscess leading to a descending necrotizing mediastinitis (DNM) is exceptional and potentially lethal, so early diagnosis with a CT scan, appropriate antibiotics and surgery are essential. The authors present a case where DNM was associated with reactive hemophagocytic syndrome as a result of infectious mononucleosis, as well as a review of similar cases in the English literature. LEARNING POINTS: The incidence of serious complications in Epstein-Barr virus (EBV) primary infection increases with age.Respiratory symptoms (e.g., pleuritic pain, dyspnoea) and unusually prolonged fever (>10 days) in patients with infectious mononucleosis could be 'red flags' for life-threatening complications such as empyema and descending necrotizing mediastinitis.The threshold for performing cervical and chest computed tomography in septic patients with infectious mononucleosis should be low.
RESUMEN
INTRODUCTION: Patients with HIV infection are at increased risk of developing cardiovascular disease (CVD) due to complex interactions between traditional CVD risk factors, antiretroviral therapy (ART) and HIV infection itself (1). Prevention of CVD is essential as it remains the most common serious non-AIDS event and contributes significantly to all-cause mortality. A cardiovascular risk-assessment model tailored to HIV population is thus essential. MATERIALS AND METHODS: We conducted a retrospective case-control study within the HIV cohort of the Saint-Pierre Hospital, Brussels. Cases (n=73) presented a first CVD (ischemic heart disease or stroke) between January 2002 and December 2012. Controls (n=142) were patients without any CVD and were matched for age, race, sex and follow-up duration. We used Wilcoxon test to identify predictors of cardiovascular risk among the data collected. We compared Framingham (2) and DAD (Data Collection on Adverse Events of anti-HIV drugs) (3) equations calculated in all patients at time of event, two, four and six years before. We then simulated the impact on the DAD scores if different therapeutic interventions had been introduced when patient cardiovascular risk at ten years exceeded 20%. RESULTS: Comparison of cases and controls showed that C-reactive protein (CRP) >3 mg/L (p=0.008) and HIV viral load >50 copies/ml (p=0.007) at time of event, as well as slower increase in CD4 cell count (p=0.035), were significantly more frequent in cases. DAD and Framingham median scores in cases and controls are shown in Figure 1 and Table 1. Smoking cessation lowered the DAD score of cases at time of event from 21.6% to 18.3%, modification of ART (discontinuation of indinavir, lopinavir and abacavir) lowered it from 21.6% to 17%, while both interventions with control of blood pressure and cholesterol lowered it from 21.6% to 12.4%. CONCLUSIONS: Increased CRP levels, uncontrolled HIV viral load at time of event and slower immunologic response were found to be associated with increased CVD risk. DAD score in cases increased more and faster over time than the Framingham score and seems therefore to be more accurate in identifying HIV-positive patients at high risk of CVD. Different therapeutic interventions could have led to a significant reduction of the DAD score in these patients and should remain a priority in patient management.
RESUMEN
BACKGROUND: Diagnosis of sepsis in the postoperative period is a challenge. Measurements of inflammatory markers, such as C-reactive protein (CRP), have been proposed in medical patients, but the interpretation of these values in surgical patients is more difficult. We evaluated the changes in blood CRP levels and white blood cell count in postoperative patients with and without infection. METHODS: All patients admitted to our 34-bed Department of Intensive Care after major (elective or emergency) cardiac, neuro-, vascular, thoracic, or abdominal surgery during a 4-month period were prospectively included. Patients were screened daily and characterized as infected or noninfected. CRP levels and white blood cell counts were recorded daily in all patients for up to 7 days after the surgical intervention. RESULTS: Of the 151 patients enrolled, 115 underwent elective surgery and 36 emergency surgery; cardiac surgery was performed in 49 patients, neurosurgery in 65, abdominal surgery in 25, vascular surgery in 7, and thoracic surgery in 5. In noninfected patients (n = 117), mean CRP values increased from baseline to postoperative day (POD) 3 (P < 0.0001, estimated mean difference [EMD] = 99.7 mg/L [95% confidence interval, 85.6-113.8]) and then decreased until POD 7 but remained higher than the level at baseline (P < 0.0001, EMD = 49.2 mg/L [95% confidence interval, 27.1-71.2]). Postoperative infection occurred in 20 patients (13.2%). In these patients, CRP values were already higher on POD 1 than in noninfected patients (P = 0.0054). CONCLUSIONS: CRP levels increase in the first week after major surgery but to a much larger extent in infected than in noninfected patients. Persistently high CRP levels after POD 4, especially when >100 mg/L, suggest the presence of a postoperative infection.

We present the case of a man with a bicuspid aortic valve who presented with persistent fever. Blood cultures yielded Neisseria gonorrhoeae, and the diagnosis of infected mycotic aneurysm was confirmed by detection of the bacterial genome in the aortic wall. The patient was cured with surgery and intravenous ceftriaxone.
