Background: Hypereosinophilic syndromes (HES) are a heterogenous group of eosinophilic disorders. To date, only retrospective studies of limited sample-size and/or follow-up duration are available.

Methods: The COHESion study is a national prospective multicenter multidisciplinary cohort recruiting both adults or children with the spectrum of eosinophilic disorders (including reactive HE/HES [HE/HES-R], idiopathic HES [HES-I], lymphocytic HES [HES-L], neoplastic HE/HES [HE/HES-N], HE of unknown significance [HE-US], as well as IgG4-related disease [IgG4RD] or ANCA-negative eosinophilic granulomatosis with polyangiitis [EGPA] overlaps).

Article Synopsis
  • The study aimed to standardize qPCR procedures for diagnosing Mucorales by examining factors that influence DNA extraction and PCR amplification efficiency.
  • Two panels of samples were distributed to 26 laboratories, and results showed that using larger serum volumes for DNA extraction and larger input volumes for PCR significantly improved detection sensitivity.
  • Findings highlight the importance of optimizing laboratory techniques to enhance diagnosis of Mucormycosis, a serious fungal infection, which is critical for timely treatment in vulnerable patients.

A ganglioside-based immune checkpoint enables senescent cells to evade immunosurveillance during aging.

Nat Aging

December 2024

Université Côte d'Azur, Centre National de la Recherche Scientifique (CNRS) UMR7284, Institut National de la Santé et de la Recherche Médicale (INSERM) U1081, Institute for Research on Cancer and Aging, Nice (IRCAN), Nice, France.

Although senescent cells can be eliminated by the immune system, they tend to accumulate with age in various tissues. Here we show that senescent cells can evade immune clearance by natural killer (NK) cells by upregulating the expression of the disialylated ganglioside GD3 at their surface. The increased level of GD3 expression on senescent cells that naturally occurs upon aging in liver, lung, kidney or bones leads to a strong suppression of NK-cell-mediated immunosurveillance.

Article Synopsis
  • Congenital titinopathies are inherited in an autosomal recessive pattern and primarily result from genetic variations in metatranscript (MTT)-only exons, leading to diverse clinical outcomes.
  • The study analyzed 20 patients with these variants, revealing severe congenital myopathy at birth along with a wide range of associated issues like muscular weakness and respiratory problems.
  • Findings underscore the importance of genotype-phenotype correlations, enhancing understanding of the genetic basis and molecular mechanisms behind these conditions.

December 2024

Department of Hematology, Hospices Civils de Lyon, CHU Lyon-Sud, Pierre-Bénite, France.

Classic Hodgkin lymphoma (HL) is a distinct entity among hematological malignancies of B-cell origin. It is characterized by its unique histopathological features and generally favorable prognosis. Over the years, advancements in understanding its pathogenesis, coupled with refined diagnostic and evaluation modalities, as well as therapeutic strategies, have significantly transformed the landscape of HL management.

  • Hematological involvement (HI) is a serious condition associated with Langerhans cell histiocytosis (LCH), and is defined by low blood cell counts indicating potential life-threatening complications.
  • A study of 2,313 children with LCH revealed that about 331 developed HI, with a distinction between mild (MHI) and severe HI (SHI), each showing different health outcomes and survival rates over 10 years.
  • Recent advances in treatment have improved mortality rates, particularly with combination therapies and targeted treatments, sparking discussions about refining HI definitions to better inform treatment strategies.

Background: Myosin heavy chain 7 ()-related myopathies (-RMs) are a group of muscle disorders linked to pathogenic variants in the gene, encoding the slow/beta-cardiac myosin heavy chain, which is highly expressed in skeletal muscle and heart. The phenotype is heterogeneous including distal, predominantly axial or scapuloperoneal myopathies with variable cardiac involvement.

Methods: We retrospectively analysed the clinical, muscle MRI, genetic and myopathological features of 57 patients.

  • Cerebral small vessel disease (SVD) can lead to various cerebrovascular issues, but research on sex differences in SVD is limited.
  • This study analyzed data from over 20,000 patients with acute ischemic stroke to examine whether the presence and severity of cerebral microbleeds (CMB) and other SVD markers differ between males and females.
  • Results showed that males had more frequent CMB while females had fewer lacunes but higher severe white matter hyperintensities, indicating distinct SVD characteristics based on sex.

Progressive multiple sclerosis poses a considerable challenge in the evaluation of disease progression and treatment response owing to its multifaceted pathophysiology. Traditional clinical measures such as the Expanded Disability Status Scale are limited in capturing the full scope of disease and treatment effects. Advanced imaging techniques, including MRI and PET scans, have emerged as valuable tools for the assessment of neurodegenerative processes, including the respective role of adaptive and innate immunity, detailed insights into brain and spinal cord atrophy, lesion dynamics and grey matter damage.

Article Synopsis
  • Acute myeloid leukemia (AML) often involves deletions of chromosome 7, which are linked to poor patient outcomes, but the full impact of other genetic changes related to this is not well understood.
  • Researchers analyzed genetic alterations in 519 AML patients, using whole-exome sequencing and a specialized gene panel, finding that mutations in TP53, which occurred in 33% of cases, were among the most common.
  • The study identified specific genes, like TP53 and PTPN11, that have a significant negative effect on overall and relapse-free survival, highlighting the complex relationship between chromosome 7 abnormalities and patient prognosis in AML.

Background: Elexacaftor-tezacaftor-ivacaftor has been approved in Europe for people with cystic fibrosis with at least one F508del CFTR variant. Additionally, it is approved by the US Food and Drug Administration (FDA) for people with cystic fibrosis with at least one of 177 rare variants. The aims of this study were to describe the clinical response to elexacaftor-tezacaftor-ivacaftor for people with cystic fibrosis without a F508del CFTR variant in France and to determine CFTR variant responsiveness to elexacaftor-tezacaftor-ivacaftor based on the observed clinical response.

French Guiana, located in the Guiana Shield, is a natural reservoir for many zoonotic pathogens that are of considerable medical or veterinary importance. Until now, there has been limited data available on the description of parasites circulating in this area, especially on protozoan belonging to the phylum Apicomplexa; conversely, the neighbouring countries describe a high parasitic prevalence in animals and humans. Epidemiological surveillance is necessary, as new potentially virulent strains may emerge from these forest ecosystems, such as Amazonian toxoplasmosis.
