Longitudinal Protocol of Polyarteritis Nodosa

Polyarteritis nodosa (PAN) is a rare immune system disorder that causes swelling and damage
to small- and medium-sized blood vessels in the body. In order to properly treat this
disease, it is critical that the level of disease activity can be determined over the course
of the disease. The purpose of this study is to determine new biological markers, or
biomarkers, that may be used to assess the severity of disease in people with PAN.

PAN, also known as systemic necrotic vasculitis, was the first recognized form of primary
systemic vasculitis. PAN causes the inflammation of small- to medium-sized blood vessels,
especially those supplying the nerves, skin, kidneys, gastrointestinal tract, heart, eye, and
genitals. Unlike another form of vasculitis called microscopic polyangiitis, PAN does not
usually cause glomerulonephritis, a type of kidney disease, or vasculitis in the very
smallest blood vessels (arterioles, capillaries, and venules). There are no radiographic or
serologic tests that can reliably measure disease activity in PAN. Currently, clinicians must
rely on patients' symptoms, signs, laboratory tests, and imaging to guide treatment
decisions, but such data are rarely consistently reliable in determining PAN disease
activity. This study will use new scientific methods to discover new biomarkers that can be
used to monitor disease activity in PAN patients. These biomarkers may be used to help direct
clinical care for PAN patients and assist in future drug development.

Study visits will occur monthly for the first year, then every 3 months thereafter for the
remainder of the study. Blood and urine collection will occur at every visit. A physical exam
and medical and medication history will occur every 3 months; also, participants will be
asked to complete several questionnaires to assess disease activity, health status, and
tobacco, alcohol, and drug use. Participants may have additional study visits if a disease
flare or disease-related complications occur during the study.

Inclusion Criteria:

- Parent or guardian willing to provide informed consent, if applicable

- Diagnosis of vasculitis

2. Presence of granulocyte or mixed leukocyte infiltrate in an arterial wall on biopsy

3. Mononeuropathy or polyneuropathy

MINOR CRITERIA

1. Weight loss of more than 4 kg (8.8 lbs)

2. Livedo reticularis, cutaneous ulcerations, or skin nodules

3. Testicular pain or tenderness

4. Myalgias

5. Diastolic blood pressure greater than 90 mm Hg

6. Elevated blood urea nitrogen (BUN) or serum creatinine levels

7. Ischemic abdominal pain
