Hyperimmunoglobulin E syndrome (HIES) with recurrent infection is a rare primary immunodeficiency characterized by the clinical triad of recurrent staphylococcal abscesses, cyst-forming pneumonia and an elevated serum immunoglobulin (Ig)E level. We report an 18-year-old man with recurrent chest infections, skin infections and dermatitis. On examination, he had the characteristic facies of HIES: high arched palate, webbing between his thumb and index finger bilaterally, and extensive scarring from multiple staphylococcal skin abscesses. He had an elevated IgE level of 14 300 kU/L. IgA and IgG deficiencies were also identified, which are rare associations of this syndrome and complicated the patient's treatment. The coexistence of HIES, IgA and IgG deficiencies has, to our knowledge, not been reported previously in the literature.

Background: Despite its proven effectiveness and safety, there are limited real-world data on CoronaVac's immunogenicity in children, especially in lower-income countries, particularly for SARS-CoV-2 variants. We present a real-world study evaluating CoronaVac's immunogenicity in Colombian children stratified by previous exposure to this virus.
Methods: 89 children aged 3-11 years were enrolled (50 Non-Exposed and 39 Exposed).

Some women infected with (CT) are asymptomatic, while others experience lower abdominal discomfort when the inflammatory process extends to the fallopian tubes. Without treatment, salpingitis can progress to pelvic peritonitis and subsequently, peritonitis in the upper abdomen, a condition known as Fitz-Hugh-Curtis syndrome, in some cases. A nucleic acid amplification assay is required for diagnosing CT infection.

Background: Dengue virus (DENV) is an arboviral pathogen found in >100 countries and a source of significant morbidity and mortality. While the mechanisms underpinning the pathophysiology of severe Dengue are incompletely understood, it has been hypothesized that antibodies directed against the DENV envelope (E) protein can facilitate antibody-dependent enhancement (ADE) of the infection, increasing the number of infected cells and the severity of disease in an exposed individual. Accordingly, there is interest in defining mechanisms for directly targeting DENV-infected cells for immunologic clearance, an approach that bypasses the risk of ADE.

Environmental heat stress causes significant economic loss in the poultry industry. Therefore, interest has increased in using feed additives to reduce the negative impacts of heat stress on the chickens and improve production performance. This study aimed to assess the effect of supplementing with Nigella sativa nanoparticles (Nano-NS) as an anti-stress and growth promoter in broiler diets under hot climatic conditions.

Background: The SARS-CoV-2 Omicron variant, since its initial detection, has rapidly spread across the globe, becoming the dominant strain. It is important to study the immune response of SARS-CoV-2 Omicron variant due to its remarkable ability to escape the majority of existing SARS-CoV-2 neutralizing antibodies. The surge in SARS-CoV-2 Omicron infections among most Chinese residents by the end of 2022 provides a unique opportunity to understand immune system's response to Omicron in populations with limited exposure to prior SARS-CoV-2 variants.
