Cogans syndrome is a rare systemic inflammatory disease characterized by a combination of audiovestibular and ocular symptoms. In some cases, systemic complications occur with vascular inflammation. Aortitis and large vessel vasculitis are the most common forms, but medium-sized and small vessel involvement has also been described. The autoimmune reaction can lead to blindness, deafness and in worst case death, if these patients remain untreated or if treatment is delayed. There is no specific blood test or imaging method available and the diagnosis is clinical. It should be suspected in patients presenting with both inflammatory eye symptoms and audiovestibular dysfunction, when more common autoimmune and infectious diseases have been excluded. The treatment consists of high dose systemic steroids, topical steroids for the affected eye and in some cases addition of immunosuppressive drugs. Treatment is based on the severity of the symptoms and how well the patient responds to initial systemic corticosteroids. Here we present a case of suspected Cogan's syndrome where diagnosis was considered after exclusion of other possible autoimmune and infectious diseases.

Background: In the UK, booster COVID-19 vaccinations have been recommended biannually to people considered immune vulnerable. We investigated, at a population level, whether the absence of detectable anti-SARS-CoV-2 spike protein IgG antibody (anti-S Ab) following three or more vaccinations in immunosuppressed individuals was associated with greater risks of infection and severity of infection.
Methods: In this prospective cohort study using UK national disease registers, we recruited participants with solid organ transplants (SOTs), rare autoimmune rheumatic diseases (RAIRDs), and lymphoid malignancies.

Background: Myocarditis tends to lead to a poor prognosis, but there are no satisfactory preventive or therapeutic strategies. Erianin, a natural benzene compound, has been found to have antioxidant and anti-inflammatory effects. However, the effects of erianin on myocarditis remain unclear.

Immunology advances have increased our understanding of autoimmune, auto-inflammatory, immunodeficiency, infectious, and other immune-mediated inflammatory diseases (IMIDs). Furthermore, evidence is growing for the immune involvement in aging, metabolic and neurodegenerative diseases, and different cancers. However, further research has indicated sex/gender-based immune differences, which further increase higher incidences of various autoimmune diseases (AIDs), such as systemic lupus erythematosus (SLE), myasthenia gravis, and rheumatoid arthritis (RA) in females.

Traditionally, research on the adaptive immune system has focused on protein antigens, but emerging evidence has underscored the essential role of lipid antigens in immune modulation. Lipid antigens are presented by CD1 molecules and activate invariant natural killer T (iNKT) cells and group 1 CD1-restricted T cells, whereby they impact immune responses to pathogens and tumors. Recent advances in mass spectrometry, imaging techniques, and lipidomics have revolutionized the identification and characterization of lipid antigens and enhanced our understanding of their structural diversity and functional significance.

The liver is an indispensable metabolic organ, responsible for accumulating and transporting various nutritional compounds in hepatocytes. However, the transport of these materials from the liver is an energetically intensive task because they contain a considerable number of hydrophobic components, including free cholesterol, and require specialized transfer proteins to shuttle these substances through an aqueous phase. Liver X receptors (LXRs) induce the expression of cholesterol transporters in macrophages to transport free cholesterol derived from apoptotic cells into extracellular space via high-density lipoproteins.
