Incidence and Risk Factors for Acute Kidney Injury during the Treatment of Methicillin-Sensitive Staphylococcus aureus Infections with Cloxacillin Based Antibiotic Regimens: A French Retrospective Study

Background: Cloxacillin has been associated with the occurrence of acute kidney injury (AKI). The incidence of this complication in the literature is low (2.5–3.5%) and probably underestimated, since most studies were done by selecting the presence of AKI in discharge codes. Objectives: The primary goal was to define the incidence of AKI in patients with a methicillin-sensitive Staphylococcus aureus infection treated with cloxacillin based antibiotic regimens. The secondary goals were to identify the risk factors associated with this complication and to describe the characteristics of AKI. Patients and methods: We carried out a retrospective study. The inclusion criteria were adult patients hospitalized in a medical department at the Le Mans Hospital between 1 July 2012 and 1 July 2019 with a diagnosis of methicillin-sensitive Staphylococcus aureus infection treated with cloxacillin. Results: One hundred twenty-three patients were included in the study. Forty-two patients (34.2%) developed AKI. In the multivariate analysis, age, the use of diuretics and the presence of endocarditis were independently associated with AKI. Age was associated with an OR of 4.38 (p = 0.002) for patients older than 75, being treated with diuretics was associated with an OR of 2.94 (p = 0.036) for loop diuretics and an OR of 3.05 (p = 0.027) for non-loop diuretics; type of infection was associated with an OR of 3.42 (p = 0.012) for endocarditis. Conclusions: The occurrence of AKI is frequent during cloxacillin based antibiotic regimens for methicillin-sensitive Staphylococcus aureus infections. Being older than 75, being treated with diuretics and the presence of endocarditis were the main risk factors for AKI in our population

Spondylodiscitis Due to Aspergillus terreus in an Immunocompetent Host: Case Report and Literature Review

International audienceAspergillus terreus, a saprophytic fungus, is recognized as an emerging pathogen responsible for various infections in human beings. However, bone and joint involvement is uncommon. We report a rare case of A. terreus spondylodiscitis in a 20-year-old male with a past history of recurrent, incompletely treated pulmonary tuberculosis. Clinical signs at the time of admission included cough, low-grade fever, general weakness and left-sided back pain. Histological examination of spinal biopsy samples revealed lesions of necrosis, granulomatous inflammation and septate hyphae with acute-angle branching. A. terreus was recovered from culture. The patient received antifungal therapy with voriconazole plus caspofungin and underwent surgical debridement. Further investigations revealed no cause of primary immunodeficiency such as chronic granulomatous disease, severe combined immunodeficiency syndrome or disorders of the IL-12/IFNγ signaling pathway. Moreover, HIV serological tests resulted negative and the patient was not under immunosuppressive therapy. Unfortunately, owing to precarity and medication non-adherence, vertebral sequelae occurred. This new report emphasizes the need to consider a fungal infection in patients with spondylodiscitis, regardless of the immune status

Impact of vaccination on the symptoms of hospitalised patients with SARS-CoV-2 Delta variant (B.1.617.1) infection

International audienceObjectives: The diffusion of the SARS-CoV-2 Delta (B.1.617.2) variant and the waning of immune response after primary Covid-19 vaccination favoured the breakthrough SARS-CoV-2 infections in vaccinated subjects. To assess the impact of vaccination, we determined the severity of infection in hospitalised patients according to vaccine status. Methods: We performed a retrospective observational study on patients hospitalised in 10 centres with a SARS-CoV-2 infection (Delta variant) from July to November 2021 by including all patients who had completed their primary vaccination at least 14 days before hospital admission and the same number of completely unvaccinated patients. We assessed the impact of vaccination and other risk factors through logistic regression. Results: We included 955 patients (474 vaccinated and 481 unvaccinated). Vaccinated patients were significantly older (75.0 [63.25-84.0] vs. 55.0 [38.0-73.0]; p < 0.001), more frequently males (55.1% (261/474) vs. 46.4% (223/481); p = 0.009), and had more comorbidities (2.0 [1.0-3.0] vs. 1.0 [0.0-2.0]; p < 0.001). Vaccinated patients were less often admitted for Covid-19 (59.3% (281/474) vs. 75.1% (361/481); p < 0.001), had less extended lung lesions (≤25%: 64.3% (117/182) vs. 38.4% (88/229); p < 0.001), required oxygen less frequently (57.5% (229/398) vs. 73.0% (270/370); p < 0.001), at a lower flow (3.0 [0.0-8.7] vs. 6.0 [2.0-50.0] L/min, p < 0.001), and for a shorter duration (3 [0.0-8.0] vs. 6 [2.0-12.0] days, p < 0.001)., and required less frequently intensive care unit admission (16.2% (60/370) vs. 36.0% (133/369); p < 0.001) but had comparable mortality in bivariate analysis (16.7% (74/443) vs. 12.2% (53/433); p = 0.075). Multivariate logistic regression showed that vaccination significantly decreased the risk of death (0.38 [0.20-0.70](p = 0.002), ICU admission (0.31 [0.21-0.47](p < 0.001) and oxygen requirement (0.16 [0.10-0.26](p < 0.001), even among older patients or with comorbidities. Conclusions: Among patients hospitalised with a delta variant SARS-CoV-2 infection, vaccination was associated with less severe forms, even in the presence of comorbidities

The effectiveness of the BuzzyⓇ device to reduce or prevent pain in children undergoing needle-related procedures: The results from a prospective, open-label, randomised, non-inferiority study

International audienceBackground: Pain from needle-related procedures in children can alter pain perception, increase pain sensitivity, and generate inappropriate pain responses. Currently pain management includes the use of lidocaine-containing patches, which is complicated to manage in a busy medical setting such as a vaccination centre. We assessed the BuzzyⓇ device, which combines vibration and cold, to manage pain in children undergoing a needle-related procedure, compared to the standard lidocaine patch.Design: Prospective, open-label, non-inferiority trial.Setting: The vaccination centres of three university hospitals in France.Participants: French speaking children aged 4-15 requiring a needle-related procedure (vaccination or venepuncture) were eligible. Principal exclusion criteria were allergy or sensitivity to the lidocaine patch.Methods: Children were randomly allocated (1:1) to use either the BuzzyⓇ device or the lidocaine patch during the needle-related procedure. The lidocaine patch was applied to the puncture site for the hour prior to the intervention. The BuzzyⓇ device was applied to the puncture site for 30 s and then moved 5 cm along the limb during the procedure. The refrigerated wings were detached if they bothered the child. The child assessed their pain using the validated Revised Faces Pain Scale. The revised faces pain scale comprised six facial expressions from 0, normal "no pain" to 10, a screaming face "severe pain" (2 points/face). The primary endpoint was the average pain score recorded by the child. The study aimed to test the non-inferiority of BuzzyⓇ.Results: Overall 219 participants were randomised. The primary outcome was assessed in 215 children: 108 in the BUZZY group (43% asked for the refrigerated wings were de to be detatched before the end of the procedure) and 107 in the PATCH group. The baseline characteristics were similar between the study groups with an average age of 9 (range: 4.08-15.81). The average needle-related pain was 2.04 in the BUZZY group and 1.42 in the PATCH group. The average difference between the children's assessments in the groups was 0.62, thus faling to demonstrate non-inferiority.Conclusions: Our study failed to show that the BuzzyⓇ device was not inferior to the lidocaine patch in managing pain in children undergoing needle-related procedures. Tweetable abstract: Pain management in children undergoing a needle-related procedure vaccination: which efficacy for BuzzyⓇ device as an alternative to lidocaine patch? A prospective, randomised study

Humoral response to a third injection of BNT162b2 vaccine in patients on maintenance haemodialysis

International audienceAbstract Background Humoral response against sudden acute respiratory syndrome coronavirus 2 (SARS-CoV-2) after two doses of BNT162b2 (Pfizer-BioNTech) has been proven to be less intense in maintenance dialysis patients as compared with healthy subjects, leading the French authorities to recommend a third injection in this population. Here we investigated the response to the third injection in two cohorts of haemodialysis (HD) patients. Methods Data from two prospective observational cohorts were collected. In the first (‘systematic’) cohort, patients from two HD centres (n = 66) received a third injection of BNT162b2, regardless of the response after two injections. In the second (‘conditional’) cohort, the injection was only prescribed to patients (n = 34) with no or low response to the previous two doses. In both cohorts, the third dose was injected 1–2 months after the second dose. Serology was performed after the second and third doses to assess anti-Spike immunoglobulin G (S IgG) antibody titre. Results In the systematic cohort, anti-S IgG was found in 83.3 and 92.4% of patients after the second and third doses of BNT162b2, respectively. In this cohort, 6/11 (54.5%) and 20/21 (95.2%) patients switched from non-responder to low responder and from low responder to high responder, respectively. In low and high responders to two doses, 50/55 (90.9%) at least doubled their anti-S IgG titre. Similar trends were observed in the conditional cohort. Conclusions In maintenance HD patients, humoral response against SARS-CoV-2 was boosted after a third dose of BNT162b2, allowing seroconversion in more than half of non-responders. These data may support an intensified vaccination protocol with a third dose of BNT162b2 in dialysis patients

Rabies Postexposure Prophylaxis Noncompletion After Dog Bites: Estimating the Unseen to Meet the Needs of the Underserved

International audiencePostexposure prophylaxis (PEP) prevents human rabies and is accessible in Cambodia principally in Phnom Penh, the capital. Timely, affordable access to PEP is a challenge for the mainly rural population. We aimed to identify districts independently associated with PEP noncompletion to position frontline vaccination centers. We analyzed the 2009–2013 database at the Rabies Prevention Center at the Institut Pasteur du Cambodge, Phnom Penh. Logistic regressions identified nongeographic determinants of PEP noncompletion as well as the districts that were independently associated with noncompletion after adjustment for these determinants. The influence of distance by road was estimated using a boosted regression-trees model. We computed a population attributable fraction (rabies index (RI)) for each district and developed a map of this RI distribution. A cartographic analysis based on the statistic developed by Getis and Ord identified clusters of high-RI districts. Factors independently associated with noncompletion were pa-tients' district of residence, male sex, age 15–49 years, initial visit during rice harvest, the dog's status (culled or disappeared), and a prescribed PEP protocol requiring more than 3 PEP sessions (4 or 5). Four clusters of high-RI districts were identified using this analytical strategy, which is applicable to many vaccination or other health services. Positioning frontline PEP centers in these districts could significantly widen access to timely and adequate PEP

Immunization Catch-Up for Newly Arrived Migrants in France: A Cross-Sectional Study among French General Practitioners

International audienceBackground: Migrants often undergo an incomplete vaccination program in regards to the French recommendations. The aim of this study was to evaluate the practices of French General Practitioners’ (GPs) in terms of catch-up vaccination. Methods: A cross-sectional study was carried-out in 2017–2018 in France. An online questionnaire was disseminated by email through scholarly societies to GPs involved in the care and the vaccination of migrants. Analyses included univariate and multivariate analysis with a logistic regression model. Results: A total of 216 GPs completed the survey. A majority identified themselves with an average level regarding the prevention of infectious diseases among migrant populations (56.7%) and confirmed this is part of their daily practice (83.3%). The majority of respondents do not perform more than two injections on the same day. When compared to GPs working in health centres, those with a private practice are more likely to report returning to a full primary vaccination schedule (adjusted OR = 2.90, 95% CI [1.29–6.53]). Aside from the serology for hepatitis B and to a lesser extent for measles, other pre-vaccination serologies were not frequently used by GPs. When a migrant declares to be up-to-date with his immunisations, only 56.5% of doctors consider this information reliable. Conclusions: This study clarified the vaccination practices of GPs receiving migrant patients in consultation and showed its heterogeneity. An important need for benchmarks has been identified and these results were used for the elaboration of the French guidelines on vaccines catch-up

Impact of vaccination on the presence and severity of symptoms in hospitalized patients with an infection of the Omicron variant (B.1.1.529) of the SARS-CoV-2 (subvariant BA.1)

International audienceObjectives: The emergence of SARS-CoV-2 variants raised questions about the extent to which vaccines designed in 2020 have remained effective. We aimed to assess whether vaccine status was associated with the severity of Omicron SARS-CoV-2 infection in hospitalized patients. Methods: We conducted an international, multi-centric, retrospective study in 14 centres (Bulgaria, Croatia, France, and Turkey). We collected data on patients hospitalized for ≥24 hours between 1 December 2021 and 3 March 2022 with PCR-confirmed infection at a time of exclusive Omicron circulation and hospitalization related or not related to the infection. Patients who had received prophylaxis by monoclonal antibodies were excluded. Patients were considered fully vaccinated if they had received at least two injections of either mRNA and/or ChAdOx1-S or one injection of Ad26.CoV2-S vaccines. Results: Among 1215 patients (median age, 73.0 years; interquartile range, 57.0–84.0; 51.3% men), 746 (61.4%) were fully vaccinated. In multivariate analysis, being vaccinated was associated with lower 28-day mortality (Odds Ratio [95% Confidence Interval] (OR [95CI]) = 0.50 [0.32–0.77]), intensive care unit admission (OR [95CI] = 0.40 [0.26–0.62]), and oxygen requirement (OR [95CI] = 0.34 [0.25–0.46]), independent of age and comorbidities. When co-analysing these patients with Omicron infection with 948 patients with Delta infection from a study we recently conducted, Omicron infection was associated with lower 28-day mortality (OR [95CI] = 0.53 [0.37–0.76]), intensive care unit admission (OR [95CI] = 0.19 [0.12–0.28]), and oxygen requirements (OR [95CI] = 0.50 [0.38–0.67]), independent of age, comorbidities, and vaccination status. Discussion: Originally designed vaccines have remained effective on the severity of Omicron SARS-CoV-2 infection. Omicron is associated with a lower risk of severe forms, independent of vaccination and patient characteristics
