Description of intervention(s) / exposure
WG classification - Patients with Wegener's granulomatosis. 1st half of these patients will be assigned to the development cohort and the second half to the validation cohort. Classification criteria.

MPA classification - Patients with microscopic polyangiitis. 1st half of these patients will be assigned to the development cohort and the second half to the validation cohort. Classification criteria.

CSS classification - Patients with Churg Strauss syndrome. 1st half of these patients will be assigned to the development cohort and the second half to the validation cohort. Classification criteria.

PAN classification - Patients with polyarteritis nodosa. 1st half of these patients will be assigned to the development cohort and the second half to the validation cohort. Classification criteria.

Control Classification - For each of the diseases being evaluated (WG, MPA, CSS, PAN, GCA, TAK), patients with the other 5 diseases will be the control group. Within these groups, 1st half of these patients will be assigned to the development cohort and the second half to the validation cohort. Classification criteria.

WG diagnostic - Patients with a new presentation of Wegener's granulomatosis. 1st half of these patients will be assigned to the development cohort and the second half to the validation cohort. Diagnostic criteria.

MPA diagnostic - Patients with a new presentation of microscopic polyangiitis. 1st half of these patients will be assigned to the development cohort and the second half to the validation cohort. Diagnostic criteria.

CSS diagnostic - Patients with a new presentation of Churg Strauss syndrome. 1st half of these patients will be assigned to the development cohort and the second half to the validation cohort. Diagnostic criteria.

PAN diagnostic - Patients with a new presentation of polyarteritis nodosa. 1st half of these patients will be assigned to the development cohort and the second half to the validation cohort. Diagnostic criteria.

Control diagnostic - Patients without vasculitis, but presenting with similar features to the 6 different types of vasculitis being studied. 1st half of these patients will be assigned to the development cohort and the second half to the validation cohort. Diagnostic criteria.

GCA classification - Patients with giant cell arteritis. 1st half of these patients will be assigned to the development cohort and the second half to the validation cohort. Classification criteria.

TAK classification - Patients with Takayasu arteritis. 1st half of these patients will be assigned to the development cohort and the second half to the validation cohort. Classification criteria.

GCA diagnostic - Patients with a new diagnosis of giant cell arteritis. 1st half of these patients will be assigned to the development cohort and the second half to the validation cohort. Diagnostic criteria.

Summary
Brief summary
Vasculitis is group of diseases where inflammation of blood vessels is the common feature.
Patients typically present with fever, fatigue, weakness and muscle and joint aches. These
symptoms are very common among many different diseases, not just vasculitis. A clustering of
other symptoms, physical examination findings, blood tests, radiology and biopsy help make
the diagnosis. There are currently no criteria to help doctors make a diagnosis of vasculitis
when a patient presents with these non specific symptoms and they are reliant on previous
experience and disease definitions. One of the aims of this project is to develop diagnostic
criteria for the primary systemic vasculitides (granulomatosis with polyangiitis (Wegener's),
microscopic polyangiitis, Churg Strauss syndrome, polyarteritis nodosa, giant cell arteritis,
Takayasu arteritis). We, the investigators, will do this by studying a large group of
patients with vasculitis and comparing them to a large group of patients that present in a
similar way, but do not have vasculitis. By comparing the 2 groups we will create a list of
items to differentiate between vasculitis and 'vasculitis mimics'.

We also aim to update the current classification criteria. Classification criteria are used
to group patients into different types of vasculitis, once a diagnosis of vasculitis has been
made, and are useful for studying patients in clinical trials with similar or identical
diseases. The current classification criteria (American college of Rheumatology 1990
criteria) were developed 20 years ago, before the availability of some important diagnostic
tests (e.g. antineutrophil cytoplasmic antibodies [ANCA]), and are now not consistent with
some of the current disease definitions. Therefore to progress future research in vasculitis,
it is important that the classification criteria are updated. We will recruit 260 patients
with each of the 6 types of vasculitis and compare them with 1300 controls (patients with the
5 other types of vasculitis), in order to determine the optimal combination of symptoms,
signs and investigations that classify each person into the appropriate group.
