Laboratory practices for the diagnosis and management of mucormycosis in France, 2024.

J Mycol Med

December 2024

Laboratoire de Parasitologie-Mycologie, Hôpital Européen Georges Pompidou, Hôpital Universitaire Necker, Unité de Parasitologie-Mycologie, Service de Microbiologie, Paris, France. Electronic address:

This study investigates the diagnostic practices for mucormycosis among 30 French University Hospital mycology laboratories, in 2024. All laboratories perform both direct examination and culture, with fluorescent brighteners being the most commonly used method for direct examination. While 77 % of the participating laboratories routinely identify Mucorales to the species level, with 70 % having adopted Mucorales-specific quantitative PCR, primarily for the diagnosis of invasive fungal infections.

Effects of Losartan on Patients Hospitalized for Acute COVID-19: A Randomized Controlled Trial.

Clin Infect Dis

September 2024

Division of Critical Care Medicine, and Centre for Heart Lung Innovation, St Paul's Hospital, Vancouver, Canada.

Article Synopsis
  • Researchers investigated the effect of losartan, an angiotensin receptor blocker, on 28-day mortality in hospitalized COVID-19 patients compared to usual care, due to its potential impact on angiotensin levels.
  • The study was stopped early due to safety concerns, showing that adverse events and hypotension were significantly higher in the losartan group (39.8% SAEs and 30.4% hypotension) versus the control group (27.2% SAEs and 15.3% hypotension).
  • There was no significant difference in 28-day mortality (6.5% for losartan vs. 5.9% for usual care), indicating that ARBs should be used cautiously in this patient population to

Background: The optimization of patient care pathways is crucial for hospital managers in the context of a scarcity of medical resources. Assuming unlimited capacities, the pathway of a patient would only be governed by pure medical logic to meet at best the patient's needs. However, logistical limitations (eg, resources such as inpatient beds) are often associated with delayed treatments and may ultimately affect patient pathways.

A growing number of patients presenting severe combined immunodeficiencies attributed to monoallelic RAC2 variants have been identified. The expression of the RHO GTPase RAC2 is restricted to the hematopoietic lineage. RAC2 variants have been described to cause immunodeficiencies associated with high frequency of infection, leukopenia, and autoinflammatory features.

Resilience after severe critical illness: a prospective, multicentre, observational study (RESIREA).

Crit Care

July 2024

Laboratoire de Psychologie: Dynamiques Relationnelles Et Processus Identitaires (Psy-DREPI), Université de Bourgogne Franche-Comté, EA7458, Dijon, France.

Background: Critical-illness survivors may experience post-traumatic stress disorder (PTSD) and quality-of-life impairments. Resilience may protect against psychological trauma but has not been adequately studied after critical illness. We assessed resilience and its associations with PTSD and quality of life, and also identified factors associated with greater resilience.

Objectives: Data about hydroxychloroquine (HCQ) levels during pregnancy are sparse. We assessed HCQ whole blood levels at first trimester of pregnancy as a potential predictor of maternal and obstetric/fetal outcomes in patients with systemic lupus erythematosus (SLE).

Methods: We included pregnant SLE patients enrolled in the prospective GR2 study receiving HCQ, with at least one available first-trimester whole-blood HCQ assay.

The use of 1E12, a monoclonal anti-platelet factor 4 antibody, to improve the diagnosis of vaccine-induced immune thrombotic thrombocytopenia.

J Thromb Haemost

August 2024

Department of Haemostasis, Regional University Hospital Centre Tours, Tours, France; Institut National de la Santé et de la Recherche Médicale INSERM U1327 ISCHEMIA, Membrane Signalling and Inflammation in Reperfusion Injuries, Université de Tours, Tours, France.

Background: Vaccine-induced immune thrombotic thrombocytopenia (VITT) is a complication of adenoviral-based vaccine against SARS-CoV-2 due to prothrombotic immunoglobulin (Ig) G antibodies to platelet factor 4 (PF4) and may be difficult to distinguish from heparin-induced thrombocytopenia (HIT) in patients treated with heparin.

Objectives: We assessed the usefulness of competitive anti-PF4 enzyme immunoassays (EIAs) in this context.

Methods: The ability of F(ab')2 fragments of 1E12, 1C12, and 2E1, 3 monoclonal anti-PF4 antibodies, to inhibit the binding of human VITT or HIT antibodies to PF4 was evaluated using EIAs.

Article Synopsis
  • Enterovirus D68 (EV-D68) infections can cause severe respiratory issues and acute flaccid myelitis, with a significant rise reported during the fall-winter season of 2021-2022 across Europe.
  • The study by the European Non-Polio Enterovirus Network (ENPEN) analyzed over 10,481 samples from 19 countries, identifying 1,004 as EV-D68, predominantly affecting young children, where 37.9% required hospitalization.
  • Additionally, genetic analyses uncovered two new B3-derived lineages without regional patterns, indicating a notable impact of the infections and the emergence of new virus strains.

Study of the antigenic characteristics of red blood cells units and their sickle cell disease recipients and the G6PD activity of transfused red blood cells units.

August 2024

Etablissement français du sang, Hôpital Henri Mondor, 1 rue Gustave Eiffel, 94010 Créteil, France; INSERM U955 équipe 2, Institut Mondor de Recherche Biomédicale (IMRB), Créteil, France.

Article Synopsis
  • Transfusion is crucial for treating sickle cell disease (SCD) and requires matching blood groups to avoid complications like alloimmunization and hemolytic reactions, with African ancestry donors generally providing the best match.
  • A study analyzed transfusion protocols and the frequency of G6PD deficiency in blood units from these donors, revealing that 35.1% of SCD patients had no antibodies and that G6PD deficiency was found in 9 units from Afro-Caribbean donors.
  • While the transfusion protocols followed guidelines to prevent immunological issues, the high rate of G6PD deficiency in compatible units poses concerns regarding the quality and outcomes of transfusions, necessitating further evaluation.

Article Synopsis
  • Moderately effective therapies (METs) have been the standard treatment for pediatric-onset multiple sclerosis (POMS), but there's still no clear consensus on treatment strategies as highly effective therapies (HETs) emerge.
  • The study aimed to evaluate the effectiveness of HET compared to MET in reducing disease activity in treatment-naive children with relapsing-remitting POMS, using a retrospective cohort design over a median follow-up of 5.8 years.
  • Results from 530 included patients indicated that both HET and MET reduced the risk of relapse within the first 2 years, with HET showing a significant 54% decrease in first relapses compared to MET.

Article Synopsis
  • The study aimed to evaluate how well the Pulmonary Embolism Rule-out Criteria (PERC) and the age-modified PERC-35 tool perform in emergency departments for patients aged 35 and younger suspected of having a pulmonary embolism (PE).
  • Data from 1,235 patients indicated that while both PERC and PERC-35 could rule out PE in nearly half the cases, there were still a few missed diagnoses.
  • Results showed that both tools had similar safety and efficacy, but the research couldn't definitively confirm their reliability due to large confidence intervals.

Background And Objective: GLUT1 deficiency syndrome (Glut1DS) is a treatable neurometabolic disease that causes a wide range of neurologic symptoms in children and adults. However, its diagnosis relies on an invasive test, that is, a lumbar puncture (LP) to measure glycorrhachia, and sometimes complex molecular analyses of the gene. This procedure limits the number of patients able to receive the standard of care.

Necker Enfants Malades Institute, INSERM U1151/CNRS UMR 8253, Action thématique incitative sur programme-Avenir Team Auto-Immune and Immune B cell, University Paris Cité, University Paris-Est-Créteil, Créteil, France.

Article Synopsis
  • * Researchers examined SARS-CoV-2 naive patients with specific genetic deficiencies and autoantibodies that affect IFN response to see if this impacted vaccine efficacy.
  • * The study found that despite these deficiencies, the B cell response, including memory B cells and IgG production, remained robust and similar to healthy individuals, indicating type I IFN isn't essential for generating a strong vaccine-induced immune response against SARS-CoV-2.
