The BSACI Registry for Immunotherapy (BRIT) is a web-based patient registry that records immunotherapy treatment of patients under the care of BSACI allergists, immunologists, GPs, dieticians and dermatologists practicing in the UK. BRIT is being rapidly adopted by centres across the United Kingdom.
Immunotherapy is a form of specialised treatment that can harness the immune system and reduce symptoms of a wide range of allergic and non-allergic diseases. BRIT focuses on immunotherapy by injection or by mouth for pollen and mite allergies, treatment of wasp and bee venom reactions, oral immunotherapy for peanut allergy (Palforzia, Stallergenes-Greer), and the use of omalizumab injections for chronic spontaneous urticaria (Xolair, Novartis).

There is a huge need to understand the effects immunotherapy has on patient outcomes. Although clinical research trials have shown benefit, it’s important that we can see this too when treating patients in the “real world” in clinic. Many registries are simply a place to put data for others to use but BRIT is not like that, there are lots of direct benefits for patients and clinicians:

The data collected by the BRIT Registry clearly highlights the unmet need for specialist allergy treatment and the inequity in access to services in the UK. As the leading national patient charity for people living with allergy in the UK, this makes the Registry a valuable tool in our discussions with decision-makers, allowing us to present the ‘real world’ patient data and treatment outcomes monitored by the Registry.
Simone Miles, CEO, Allergy UK
We’re delighted to partner with the BRIT registry. Collecting real-world data is essential to understand how immunotherapy performs in everyday clinical practice and how it affects patients’ quality of life. This evidence will strengthen commissioning decisions and guideline development, and help make immunotherapy more accessible. Our helpline hears daily from people desperate for treatment, so we’re proud to support a project that aims to broaden access and improve understanding — so more people living with allergies can benefit from this life-changing treatment.
