Background: Vaccines that minimize the risk of vaccine-induced antibody-dependent enhancement and severe dengue are needed to address the global health threat posed by dengue. This study assessed the safety and immunogenicity of a gold nanoparticle (GNP)-based, multi-valent, synthetic peptide dengue vaccine candidate (PepGNP-Dengue), designed to provide protective CD8+ T cell immunity, without inducing antibodies.

Methods: In this randomized, double-blind, vehicle-controlled, phase 1 trial (NCT04935801), healthy naïve individuals aged 18-45 years recruited at the Centre for primary care and public health, Lausanne, Switzerland, were randomly assigned to receive PepGNP-Dengue or comparator (GNP without peptides [vehicle-GNP]).

The humoral responses of Ebola virus (EBOV) survivors mainly target the surface glycoprotein GP, and anti-GP neutralizing antibodies have been associated with protection against EBOV infection. In order to elicit protective neutralizing antibodies through vaccination a native-like conformation of the antigen is required. We therefore engineered and expressed in CHO cells several GP variants from EBOV (species , Mayinga variant), including a soluble GP ΔTM, a mucin-like domain-deleted GP ΔTM-ΔMUC, as well as two GP ΔTM-ΔMUC variants with C-terminal trimerization motifs in order to favor their native trimeric conformation.

Over the last four decades, significant efforts have been invested to develop vaccines against malaria. Although most efforts are focused on the development of vaccines, the current availability of the parasite genomes, bioinformatics tools, and high throughput systems for both recombinant and synthetic antigen production have helped to accelerate vaccine development against the parasite. We have previously identified several and proteins containing α-helical coiled-coil motifs that represent novel putative antigens for vaccine development since they are highly immunogenic and have been associated with protection in many functional assays.

Allergy to furry animals is a frequent health issue, and should be suspected when investigating any yearlong rhinoconjonctivitis or asthma. A detailed medical history and skin prick tests are usually sufficient for diagnosis, and if necessary, specific IgE testing may be performed. In case of proven hypersensitivity, avoidance of animal allergens is the main therapeutic measure, primarily by removing the animal from the patient's environment, in association with symptomatic treatment.

P27A is a novel synthetic malaria vaccine candidate derived from the blood stage protein Trophozoite Exported Protein 1 (TEX1/PFF0165c). In phase 1a/1b clinical trials in malaria unexposed adults in Switzerland and in malaria pre-exposed adults in Tanzania, P27A formulated with Alhydrogel and GLA-SE adjuvants induced antigen-specific antibodies and T-cell activity. The GLA-SE adjuvant induced significantly stronger humoral responses than the Alhydrogel adjuvant.

Allergy transfer upon solid organ transplantation has been reported in the literature, although only few data are available as to the frequency, significance, and management of these cases. Based on a review of 577 consecutive deceased donors from the Swisstransplant Donor-Registry, 3 cases (0.5%) of fatal anaphylaxis were identified, 2 because of peanut and 1 of wasp allergy.

Background: Clinically meaningful specific IgE determination is an important step in the diagnosis of allergic diseases. While patient's history and skin prick tests are available during the medical visit, most IgE immunoassays require hours to several days to be available. Recent developments in the field of nanofluidic technology open new horizons for point-of-care management of this unmet medical need.

Article Synopsis
  • - The study focuses on how effective vaccination relies on the cooperation between specific B cells and T follicular helper (Tfh) cells, which are crucial for generating protective immunity.
  • - Researchers discovered a type of circulating Tfh cells in humans that resemble Tfh cells found in the germinal centers, and they explored how different vaccine formulations influence these cells.
  • - An experimental malaria vaccine with a specific adjuvant (GLA-SE) was shown to successfully expand Tfh cells and improve long-lasting antibody responses, suggesting that changing vaccine adjuvants can enhance Tfh differentiation and overall vaccine effectiveness.

Immune-checkpoint inhibitors (ICIs), including anti-cytotoxic T lymphocyte antigen 4 (CTLA-4), anti-programmed cell death 1 (PD-1) and anti-programmed cell death 1 ligand 1 (PD-L1) antibodies, are arguably the most important development in cancer therapy over the past decade. The indications for these agents continue to expand across malignancies and disease settings, thus reshaping many of the previous standard-of-care approaches and bringing new hope to patients. One of the costs of these advances is the emergence of a new spectrum of immune-related adverse events (irAEs), which are often distinctly different from the classical chemotherapy-related toxicities.

Asthma is a chronic disease that is still frequently poorly controlled, despite recent advances in understanding its pathophysiology. Poor compliance and ineffective inhalation technique remain the main causes of treatment failure. The comorbidities associated with asthma, such as obesity and chronic rhinosinusitis, are other elements to consider in the management of patients.

In allergology, food allergy is probably the problem to which medicine has brought the least therapeutic response so far. While oral immunotherapy for peanut, egg and milk is reserved for a few special cases and is not routinely recommended, apple desensitization for adult oral syndrome seems to bring some benefits in clinical practice, particularly in patients with restricted diet in fruits.

Immune checkpoint inhibitors are reshaping the prognosis of many cancer and are progressively becoming the standard of care in the treatment of many tumour types. Immunotherapy is bringing new hope to patients, but also a whole new spectrum of toxicities for healthcare practitioners to manage. Oncologists and specialists involved in the pluridisciplinary management of patients with cancer are increasingly confronted with the therapeutic challenge of treating patients with severe and refractory immune-related adverse events.

Background & Aims: Individualized supplemental parenteral nutrition (SPN) providing measured energy expenditure from day 4 reduced infectious complications in a previous study including 305 intensive care (ICU) patients. The study aimed at investigating the metabolic, and immune responses underlying the clinical response of the previous trial.

Methods: Randomized controlled trial enrolling 23 critically ill patients on day 3 (D3) of admission to the ICU who were fed less than 60% of their energy target by the enteral nutrition (EN) alone: allocation to either continued EN or to SPN to a target validated by indirect calorimetry.
