COVID-19 PBMCs are doubly harmful, through LDN-mediated lung epithelial damage and monocytic impaired responsiveness to live exposure.

Front Immunol

June 2024

Laboratoire d'Excellence Inflamex, Institut National de la Santé et de la Recherche Medicale U1152, Physiopathologie et Épidémiologie des Maladies Respiratoires, Université de Paris-Cité, Paris, France.

Article Synopsis
  • The study emphasizes the under-researched role of myeloid cells, particularly monocytes and low-density neutrophils (LDNs), in COVID-19 disease and their impact on immune responses, especially against secondary bacterial infections.
  • Findings reveal that COVID patients show increased LDNs that damage type II alveolar cells and that monocytes in COVID patients exhibit reduced responsiveness to bacterial infections, indicating impaired immune function in severe cases.
  • Overall, the results suggest that COVID-19 alters the immune environment, leading to a biased T cell response and harmful functions of myeloid cells, which can exacerbate lung damage and hinder effective defenses against infections.

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.

Introduction: Weight loss after bariatric surgery causes very important modifications to the patient's silhouette. Abdominal fat and skin excess reduction are associated with several complications. The most frequent are seroma and hematoma whereas major complications, such as pulmonary embolism, are less frequent.

Drug-resistant tuberculosis (DR-TB) is a major public health concern worldwide. The prolonged isolation required is a source of challenges for both healthcare workers and patients, especially in high-income countries where DR-TB patients are frequently migrants with vulnerabilities. However, data on the needs of these vulnerable patients are scarce.

Effects of Standard-Dose Prophylactic, High-Dose Prophylactic, and Therapeutic Anticoagulation in Patients With Hypoxemic COVID-19 Pneumonia: The ANTICOVID Randomized Clinical Trial.

JAMA Intern Med

June 2023

Université Paris Est Créteil, Institut Mondor de Recherche Biomédicale, Groupe de Recherche Clinique CARMAS (Cardiovascular and Respiratory Manifestations of Acute lung injury and Sepsis), Créteil, France.

Article Synopsis
  • The study focused on determining the best type of anticoagulation therapy for COVID-19 pneumonia patients to reduce mortality and disease duration, comparing therapeutic anticoagulation (TA), high-dose prophylactic anticoagulation (HD-PA), and standard-dose prophylactic anticoagulation (SD-PA).
  • Conducted in France, the ANTICOVID trial involved 334 patients with hypoxemic COVID-19 pneumonia, all requiring supplemental oxygen, and aimed to understand the effects of these treatments over a 14-day period.
  • Results indicated that HD-PA and SD-PA had similar outcomes, as did TA when compared to SD-PA, suggesting no significant advantage for either anticoagulation strategy in improving patient outcomes by day

Purpose Of Review: Managing antimicrobial therapy in patients with complicated skin and soft tissue infections (SSTI) constitutes a growing challenge due to the wide spectrum of potential pathogens and resistance phenotypes. Today, microbiological documentation relies on cultural methods. This review summarizes the available evidence regarding the clinical input of rapid microbiological diagnostic tools (RMDT) and their impact on the management of antimicrobial therapy in SSTI.

Fournier's gangrene is a necrotizing soft tissue infection of the genital, perineal, and perirectal areas. A primary isolated involvement of the penis is rare, but it can be affected in some circumstances. The purpose of this case series is to present the findings of our thirteen years' experience in the reconstruction of the penis in Fournier's gangrene and our full-thickness grafting technique to cover the penis rod.

Background: Fournier's gangrene is a rare form of necrotizing fasciitis that affects the genital area up to the perineal region and sometimes the abdominal wall.

Objectives: Our article aims to show that in the treatment of extensive forms of Fournier's gangrene, correct use of flap and skin grafts and a quick reconstruction of the exposed tissues avoid scarring retraction of the testicles and deformation of the penis.

Materials And Methods: We retrospectively reviewed the clinical and photographic data of Fournier's gangrene cases treated at our Institute.

Introduction: The most common malignancies metastasizing to the heart are cancers of the lung, breast, mesothelioma, melanoma, leukemia, and lymphoma. Cardiac metastasis from a tongue cancer is a rare finding and only a few cases have been reported previously in the literature. In this case report and literature review, we discuss the main clinical features of patients with cardiac metastases secondary to a tongue cancer and imaging modalities performed, especially the 18F-Fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT).

Tattoo complications in treated and non-treated psoriatic patients.

J Eur Acad Dermatol Venereol

April 2020

Dermatology Department, Hôpital Victor Dupouy, Argenteuil, France.

Background: Tattooing is a widespread phenomenon, with an estimated prevalence of 10-30% in Western populations. For psoriasis patients, current recommendations are to avoid having a tattoo if the disease is active and they are receiving immunosuppressive treatments. Although scientific data supporting these recommendations are lacking, dermatologists are often reluctant to advocate tattooing in psoriasis patients.

Article Synopsis
  • Acquired Glanzmann thrombasthenia (GT) is a bleeding disorder typically linked to autoantibodies against α β integrins, which are critical for normal platelet function.
  • A case study is presented of a patient experiencing a progressive GT-like condition, resulting in severe platelet aggregation defects and gastrointestinal bleeding, caused by a specific IgM autoantibody affecting platelet signaling.
  • The patient's condition demonstrated novel insights into α β integrin signaling pathways and how autoantibodies can lead to platelet dysfunction and dysmegakaryopoiesis, prompting further investigation into the mechanisms behind this abnormality.
