IgG4-related pachymeningitis
MONDO:0018673Idiopathic hypertrophic pachymeningitis (IHP) is a rare disorder causing inflammation and thickening of the outer layer (dura) of the brain and/or spinal cord. IHP can be widespread or cause tumor-like lesions. Before IHP can be diagnosed, other conditions including sarcoidosis, tumors, meningioma, infections (syphilis, tuberculosis, and Lyme disease), and autoimmune diseases (rheumatoid arthritis, Sjogrenbs syndrome, Wegenerbs granulomatosis, and IgG4-related disease) must be ruled out. IHP often presents with headache and cranial nerve impairment. Treatment may involve prednisone and/or an immune suppressing drug. This treatment often improves symptoms, however complete recovery is rare. Surgery may be recommended for people with advanced or severe IHP. Some people with IHP have no symptoms and may not need treatment.
Also known as: idiopathic hypertrophic pachymeningitis, idiopathic hypertrophic cranial pachymeningitis, idiopathic hypertrophic craniospinal pachymeningitis, idiopathic hypertrophic spinal pachymeningitis

Fetal stem cells aim to tame immune chaos
Disease control ENROLLING_BY_INVITATIONThis early-stage trial tests clonal fetal mesenchymal stem cells (cfMSCs) in 100 people with severe immune-related disorders or tissue damage. The goal is to see if the cells are safe and can reduce symptoms. Participants have no other treatment options left.

Experimental CAR-T therapy targets tough autoimmune conditions
Disease control ENROLLING_BY_INVITATIONThis early-phase study tests a new type of CAR-T cell therapy in 9 people with autoimmune diseases that have not responded well to standard treatments. The therapy uses specially engineered immune cells to target and attack faulty immune cells. The main goal is to check safety an…

New tool could predict who will suffer from steroid side effects
Knowledge-focused OngoingThis study aims to create a tool that predicts which patients with inflammatory rheumatic diseases (like rheumatoid arthritis, vasculitis, or polymyalgia rheumatica) will develop serious side effects from long-term steroid use. Researchers will collect routine medical data—such a…

Immune cell showdown: autoimmune vs. infection vs. healthy
Knowledge-focused ENROLLING_BY_INVITATIONThis study looks at immune cells from people with autoimmune diseases (like lupus), people with infections, and healthy volunteers. Researchers want to understand how these cells differ and what makes them attack the body in autoimmune conditions. The study involves blood and bon…
