What is vasculitis?

Vasculitis intro

Vasculitis means ‘inflammation of the blood vessels’.

It leads to a variety of conditions which can affect any organ. Most commonly kidneys, lungs, skin and joints are affected.

Vasculitis 02

Vasculitis is an Autoimmune diseases, which means your immune system (which normally serves to protect us from infections and cancers) attacks the blood vessels by mistake.

Individual vasculitis cases are rare, but taken together they affect thousands of patients in the UK. Currently there are no cures for vasculitis, but the diseases can be controlled.

Vasculitis 03

Vasculitis may be secondary to provoking factors, most commonly an infection (e.g. hepatitis), or certain drugs (recreational or prescribed).

Or it may be primary form of Autoimmune diseases caused by a faulty immune system.

Vasculitis 04

Systemic vasculitis diseases affect many organs. They have periods of activity and remission.

The diseases can cause significant harm, both acutely when they first manifest themselves and long term in the form of chronic organ damage.

Vasculitis 05

Systemic vasculitis may be associated with abnormal antibodies, such as ANCA.

Levels of these antibodies are measured by blood tests which help decide on treatment decisions.

The image shows different types of ANCA, called p-ANCA (or MPO-ANCA) and c-ANCA (or PR3-ANCA), identified by their staining pattern. Different ANCA types are associated with different disease patterns.

Vasculitis 06

Treatment for vasculitis generally involves long term drugs called immunosuppressents, which are tailored to each individual’s needs.

Understanding how best to manage and improve these drug treatments is what vasculitis experts spend their time working on.

Vasculitis 07

Genetic risk factors have been identified for many vasculitic syndromes, but a second factor is usually required to provoke the disease, often in the form of an infection.

Rarely, vasculitis can run in families.

Improving the way we use our current medicines for treatment

Individualising the way we treat patients

Predicting who is more or less likely to relapse so that treatment can be tailored to them

Developing new ways of switching off the disease on a more permanent basis
