WHAT IS VASCULITIS?
VASCULITIS IS A DIVERSE CATEGORY OF INFLAMMATORY DISEASES OF BLOOD VESSELS.• RANGE IN SEVERITY FROM SELF LIMITED DERMATOLOGIC CONDITIONS TO ACUTE AND RAPIDLY FATAL MULTISYSTEM DISEASES.• ALL FORMS OF VASCULITIS ARE CHARECTERISED BY ENDOTHELIAL DAMAGE, INTIMAL PROLIFERATION, THROMBOSIS AND EVENTUAL VASCULAR OCCLUSION.• VASCULITIS CAN AFFECT EVERY ORGAN SYSTEM.

FIBRINOID NECROSISFibrinoid necrosis is a form of necrosis, or tissue death, in which there is accumulation of amorphous, basic, proteinaceous material in the tissue matrix with a staining pattern reminiscent of fibrin.

WHEN SHOULD VASCULITIS BE SUSPECTED?
• MULTISYSTEM inflammatory disease• Sign. CONSTITUTIONAL SYMPTOMS• RAPIDLY PROGRESSIVE organ dysfunction • HIGH ESRSEVERE anemiaPLATELETS > 500K• Low serum ALBUMIN
CLINICAL FEATURES PARTICULARLY S/Oof small vessel inflammation:
• SKIN: palpable purpura • LUNGS: pulmonary infiltrates /
hemoptysis • KIDNEY: active urinary
sediment• NEURO: foot drop

TAKE THESE CLUES…..
• Palpable purpura =small vessel leukocytoclastic vasculitis• Hepatitis B PAN• Wrist/foot drop= PAN• Hepatitis C =cryoglobulinemia• Oral & genital ulcers =Behcet’s
Upper/lower airway disease and glomerulonephritis = Wegener’s• Septal perforation, epistaxis• Recurrent sinus infections
Asthma and eosinophilia= CSV
• Young female with arm/leg fatigue and HTN =
Takayasu’s

Unexplained ischemia, such as claudication, limb ischemia, angina, transient ischemic attack, stroke, mesenteric ischemia and cutaneous ischemia, particularly in a young patient or a patient without risk factors for atherosclerosis
When should vasculitis be suspected?

CUTANEOUS MANIFESTATION
Palpable Purpura
Caused by extravasation of RBCs from small vessels that have been occluded by immunecomplexes. They are heavy and tend to occur in the most gravity dependent area of the body
![Page 16: Systemic vasculitis 2016 shj](https://reader035.fdocuments.in/reader035/viewer/2022062302/58eebfa51a28ab196c8b45d9/html5/thumbnails/16.jpg)

LIVEDO RETICULARIS
All of us develop this “lacy” vascular pattern when we are cold. However livedo reticularis is caused by relative ischemia of the capillary beds. Vasculitis is one of the causes of livedo.

SPLINTER HEMORRHAGES
Splinter hemorrhages can be found in the distal nail bed and/or in the periungual area.

No universally accepted classification system.• Vessel size• Histopathology• Dominant organ
involvement. The clinical features of primary vasculitis syndromes often OVERLAP, and many patients do not fit neatly into a well-defined type of vasculitis

CHAPEL HILL CLASSIFICATION
Large vessels : Aorta and its major branches and the analogous veins. Medium vessels: The main visceral arteries , veins and their initial branches. Small vessels : Intraparenchymal arteries, arterioles, capillaries, venules, and veins. The kidney is used to exemplify medium and small vessels.

TISSUE BIOPSY “GO WHERE THE MONEY IS”
Blind biopsy generally low yield of < 20%.Vasculitic lesions tend to be focal and segmental.If a patient is over age 50 Y. and presents with a new, unexplained headache and elevated ESR, with or without a tender or abnormal temporal artery, a temporal artery biopsy would be indicated.
Similarly, in a patient who presents with a multisystem illness and testicular pain and swelling, a testicular biopsy should be considered. Sural nerve biopsy may be indicated in a patient with numbness and tingling in a lower extremity.If the urine sediment is abnormal, a renal biopsy might be obtained.
![Page 34: Systemic vasculitis 2016 shj](https://reader035.fdocuments.in/reader035/viewer/2022062302/58eebfa51a28ab196c8b45d9/html5/thumbnails/34.jpg)
05/02/2023
ANGIOGRAM
• If biopsy is impractical• Important in large vessel vasculitis• Patient with abdominal pain• Renal or mesenteric vasculitisIf visceral involvement is suspected (and in the absence of a surgical abdomen),
a visceral angiogram to include the celiac, mesenteric, renal and, perhaps, hepatic arteries should be performed .

KAWASAKI DISEASE : F E B Ri L E
Kawasaki disease (KD) is an acute febrile vasculitic syndrome of early childhood that, (although it has a good prognosis with treatment) can lead to death from coronary artery aneurysm (CAA) in a very small percentage of patients.
CRITERIA • Fever • Enanthem • Bulbar conjunctivitis • Rash • Internal organ involvement (not part of the criteria) • Lymphadenopathy • Extremity changes
![Page 49: Systemic vasculitis 2016 shj](https://reader035.fdocuments.in/reader035/viewer/2022062302/58eebfa51a28ab196c8b45d9/html5/thumbnails/49.jpg)
05/02/2023
ANCA ASSOCIATED VASCULITIS• They have been classified together in the recent 2012 Chapel Hill classification system.• GPA and MPA have been considered together in clinical and treatment studies because they share many clinical features. • Renal involvement is identical in both diseases with a pauci immune FSGN. Granulomatous involvement, of the upper respiratory tract, is a characteristic feature of GPA, but not of MPA• Eosinophilia, asthma and atopy typically occur in EGPA

TYPES OF ANCA ASSOCIATED VASCULITIDES
There are 3 forms of ANCA-associated vasculitis. • Granulomatosis with
polyangiitis (GPA) • Formerly known as
Wegener's granulomatosis• Microscopic polyangiitis (MPA)• Eosinophilic granulomatosis
with polyangiitis (EGPA) • Formerly known as Churg-
Strauss syndrome

WEGENER’S GRANULOMATOSIS (GPA)
• Necrotizing vasculitis that affects the small vessels of the respiratory tract and renal system : PULMONARY-RENAL SYNDROME
• Age ~ 40s: M > F 2:1• Sinusitis
• Nasal septal ulceration• Pneumonitis
• few symptoms until late• usually no mediastinal
lymphadenopathy• nodules that can cavitate
ACR CRITERIA (3 OUT OF 5)1.Nasal or oral inflammation (oral ulcers or bloody nasal drainage)2.Abnormal chest radiograph (nodules, fixed infiltrates, cavities)3.Urinary sediment (> 5 RBC/ hpf or casts)4.Abnormal Biopsy: showing vasculitis5.Proteinase-3 antibodies

WEGENER’S GRANULOMATOSIS (GPA)
A 65yo. woman c/o 6 months of malaise, 9 lb weight loss, recurrent sinusitis, and a persistent cough. On exam, she is afebrile, the mid-portion of the nasal bridge has a flattened appearance, and both sides of the nasal septum are ulcerated. RF is positive and ESR is 66.
• Which of the following tests would be most helpful in determining the diagnosis:A. Nasal septum biopsyB. Chest radiographC. Measurement of ANCA antibodiesD. Sputum cultureE. Measurement of anti-GBM antibodies

VASCULITIS: ACTIVITY Vs. DAMAGES
Disease Activity
Disease Damage
Even after achieving disease remission, patients will continue to suffer from the chronic, irreversible consequences of both the disease and its therapies

TAKE HOME MESSAGE• The systemic vasculitides are chronic diseases, usually autoimmune , characterized by relapse and remission• Ultimate diagnosis is almost always biopsy• Achieving remission requires intense monitoring by an expert multidisciplinary team • Therapy of choice usually involves corticosteroids and sometimes an adjunctive cytotoxic• Pain and fatigue are common consequences independent of disease activity and generally fail to respond to immunosuppression
