    Insights

    Kawasaki disease (KD) is an acute vasculitis affecting children. Intravenous immunoglobulin (IVIG) treats KD, but some patients are resistant, necessitating further research into IVIG mechanisms and alternative therapies.

    Area of Science:

    • Pediatric rheumatology
    • Immunology
    • Vascular biology

    Context:

    • Kawasaki disease (KD) is an acute, self-limited vasculitis affecting primarily infants and children.
    • Coronary artery (CA) aneurysms are a severe complication, occurring in 25% of untreated children.
    • Intravenous immunoglobulin (IVIG) is the standard treatment, reducing CA aneurysm incidence.

    Purpose:

    • To review the clinical utility of IVIG in Kawasaki disease.
    • To describe the proposed mechanisms of IVIG's anti-inflammatory activity in KD.
    • To highlight the challenges and implications of IVIG resistance in KD patients.

    Summary:

    • KD is an acute vasculitis with potential for severe coronary artery (CA) complications.
    • IVIG is effective in most KD cases, reducing CA aneurysms.
    • 10-20% of KD patients exhibit IVIG resistance, posing a higher risk for CA abnormalities.

    Impact:

    • Understanding IVIG mechanisms can optimize KD treatment strategies.
    • Identifying mechanisms of IVIG resistance may lead to improved therapies for non-responders.
    • This review provides insights into managing KD and preventing its severe cardiovascular sequelae.

    Tumor Immunotherapy

    Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.

    Drugs for Treatment of Crohn's Disease in IBD Using Biologic Agents: Anti-TNF

    Tumor Necrosis Factor (TNF), a proinflammatory cytokine, contributes significantly to the inflammation seen in Crohn's disease. It exists as soluble TNF and membrane-bound TNF, with actions mediated through TNF receptors (TNFR). TNFR activation leads to the release of proinflammatory cytokines, T-cell activation, collagen production, and leukocyte migration, all contributing to inflammation in Crohn's disease. Anti-TNF monoclonal antibodies, namely infliximab (Remicade), adalimumab...

    Immunological Memory

    Immunological memory, a pivotal pillar of the adaptive immune system, is responsible for the body's ability to remember and respond more swiftly and effectively to previously encountered pathogens. This remarkable feature is what makes vaccines so effective in preventing diseases.
    What is Immunological Memory?
    Immunological memory is an integral function of the immune system that allows it to recognize and react more rapidly and effectively to pathogens previously encountered. This feature...

    Immunoprecipitation

    Immunoprecipitation, or IP, is a widely used technique that employs protein-antibody interactions to isolate proteins or protein complexes in their native state for studying protein-protein interactions, quaternary structures, or supramolecular complexes. Various modifications of the technique, including chromatin IP, cross-linking IP, and fluorescence IP, are commonly used.
    Chromatin Immunoprecipitation

    Drugs for Treatment of Crohn's Disease in IBD Using Immunomodulatory Agents

    Crohn's disease is an inflammatory bowel disorder marked by chronic inflammation of the GI tract. Various treatment strategies for Crohn's disease are employed, such as immunomodulatory agents, glucocorticoids, and biologics or anti-TNF therapy. Azathioprine (Imuran), a commonly used immunomodulatory drug for Crohn's disease, is converted in the body to mercaptopurine, which inhibits purine biosynthesis and cell proliferation. Both are utilized in severe cases of Inflammatory Bowel...
