The association between the presence of anti-interferon-γ autoantibodies and the onset of immunodeficiency with intracellular infections has been clearly established. No standard regimen to control the production of these pathogenic autoantibodies, apart from antimicrobial therapy to eliminate infections, contributes to the medical burden of this syndrome, which sometimes has a fatal outcome. In this review, we summarize the findings on anti-interferon-γ autoantibodies to facilitate further research and to provide guidance for treatment strategies.

Rationale: Locked-in syndrome (and its variant, completely locked-in state) generally has a high mortality rate in the acute setting; however, when induced by conditions such as acute inflammatory polyradiculoneuropathy, it may well be curable such that an attempt at cure should be systematically sought by clinicians.
Patient Concerns: A 52-year-old man presented with acute tetraparesia and areflexia, initially diagnosed as Guillain-Barré syndrome. Despite appropriate treatment, his condition deteriorated, evolving into a completely locked-in state.

Bullous pemphigoid (BP) is a debilitating autoimmune skin blistering disease, characterized by the deposition of specific autoantibodies at the dermal-epidermal junction. This leads to an inflammatory cascade involving the activation of complement proteins, mast cell degranulation, immune cell recruitment, and the release of proteases by granulocytes. While several cytokines and signaling pathways have been implicated in the pathogenesis of BP, the precise mechanism behind autoantibody production remains unclear.

Little is known about how patients with antiphospholipid syndrome (APS) or antiphospholipid antibodies (aPL) access and trust health information. This research aimed to: describe the sources of information most frequently accessed/trusted by patients with APS/aPL; identify if individuals with APS/aPL perceived their health had been negatively impacted by various sources and document obstacles to accessing health information. Patients meeting Revised Sapporo Criteria for APS or with ≥1 positive aPL on ≥2 occasions were recruited to an online survey regarding their health information use at diagnosis and within 6 months preceding survey completion.

Background: We previously identified circulating and MRI biomarkers associated with the surgical management of Crohn's disease (CD). Here we tested associations between these biomarkers and ileal resection inflammation and collagen content.
Methods: Fifty CD patients undergoing ileal resection were prospectively enrolled at 4 centers.

Multiple sclerosis (MS) is a chronic immune-mediated neurological disorder, characterized by progressive demyelination and neuronal cell loss in the central nervous system. Many possible causes of MS have been proposed, including genetic factors, environmental triggers, and infectious agents. Recently, epsilon toxin (ETX) has been incriminated in MS, based initially on the isolation of the bacteria from a MS patient, combined with an immunoreactivity to ETX.
