PPiP2 – Prevalence of Neuronal Cell Surface Antibodies in Patients with Psychotic Illness

The study aims to understand more about the role of the immune system in psychosis. There is some evidence to suggest that in some people their immune system may play a part in their symptoms of psychosis.

The immune system normally controls our ability to fight infection.  If the immune system goes wrong it may attack our own body, causing diseases called ‘autoimmune’ diseases.  It has been discovered that some of these autoimmune diseases can affect the brain, and in the early stages of the disease they can manifest through symptoms of psychosis.

We can diagnose some of these autoimmune diseases using blood tests to detect specific antibodies.  We are specifically interested in NMDAR, LGI1, GABA-A and CASPR2 antibodies that may be associated with symptoms of psychosis. Participants with presence of these antibodies in their serum will be referred to neurologist and approached for the SINAPPS2 trial on immunotherapy (IVIG/Rituximab) for antibody associated psychosis.

The UK MS Register Project

The UK MS Register project is a joint initiative between Swansea University, the Multiple Sclerosis Society and a number of senior clinicians and academics at NHS Hospitals across the United Kingdom. The goal of the Register is to build a longitudinal research-ready database of people with MS in the UK, consisting of linked data from clinicians, people with MS, and routine MS data.

NHS Clinical Sites consent patients over the age of 18 with a confirmed diagnosis of MS who agree to have their medical records (including an established dataset, clinic letters and even MRIs) linked to the MS Register. Routine sources of anonymised data such as Hospital in and outpatient records will be linked to these datasets going forward. The security and confidentiality of this data is of the highest importance and the highest levels of encryption and security throughout its collection, storage and use are in place. All data that researchers have access to is anonymised and nothing identifiable is ever released.

Further information about the trial can be found at

Study closes:  08/07/2022

The MS Registry has produced a short video on the data it has collected on MS and COVID-19 and the research that it has generated.
