- ? Wegener’s Granulomatosis
PLAN : Renal biopsy

INJ Frusemide 20 mg IV BD , 2 days
INJ Methyl prednisolone 1 g in 100 ml NS IV infusion
over 1 hr , 3 days followed by
Tab Prednisolone 60 mg/day ( 1 mg/kg bw)
29. ANCA
1982 –Davies & colleagues first described ANCA ;
Two types – c ANCA & p ANCA (IFA);
Antigens associated are
-- proteinase 3-PR3 – c ANCA
--myeloperoxidase –MPO-p ANCA
• ANCA positivity by IFA should be confirmed by antigen
specific testing for both PR3 & MPO
30. DISEASE ASSOCIATIONS
Vasculitis :-
: small vessel vasculitis – WG,MPA,CSS
: idiopathic necrotising crescentic glomerulonephritis
Sensitivity of ANCA -50 to 90 %
-Negative test does not rule out diagnosis in
patients with high pretest probability
Specificity of ANCA ;
: If IFA results are combined with antigen specific assays,the
specificity of both PR3-ANCA & MPO-ANCA is exceedingly high.
• Influences disease phenotype
-- PR3 – WG; MPO - MPA
-- PR3 positive patients -> more relapse
->more granuloma
-> more extrarenal
31. others..
Rheumatoid arthritis ,SLE, myositis
Cystic fibrosis , endocarditis ,& HIV
Inflammatory bowel disease :UC > crohn’s
Sclerosing cholangitis ,autoimmune heaptitis
Drugs :
Hydralazine ,propylthiouracil high MPO-
D penicillamine ,minocycline ANCA
32. Wegener’s granulomatosis
• First described in 1931 by Heinz Klinger ;
• Classic triad-Granulomatous necrotising vasculitis affecting the
upper & lower respiratory tract and the kidneys;
• Prevalence – 3/1,00,000 persons
• Affects both sexes equally ;
• Affects all ages –( mean age 41 yrs );
• More common in Caucasians
33. Pathogenesis
Exact cause unknown;
HLA-DR1 & HLA-DQw7 association has been reported ;
PR3-ANCA antibodies are highly specific for Wegener’s
(90-97%);
ANCA s cause neutrophil degranulation & also cause
endothelial damage ;
Evidence of T cell involvement is less direct ;
34. Clinical features
Predilection for upper,lower respiratory tract & the
kidneys ;
Mild forms of wegener’s without renal involvement
have been described ;
Indolent or rapidly progressive course ;
Unexplained constitutional symptoms like fever and
weight loss in one fourth of the patients
35. Upper airway features
Most common presenting feature
In 70 % of the patients at onset ,ultimately developing in
>90%
Sinusitis(MC) initial presentation in 50 -67%;in85 %
during the course of the disease
Secondary infection-S. aureus is predominant organism;
Epistaxis -11-32%
Biopsy - granulomatous inflammation with necrosis ;
vasculitis+/-
- complete diagnostic triad in 3 – 16%
36. Renal manifestations
Presence or absence of renal disease defines generalised or
limited wegener’s ;
Early disease mey be clinically silent
Extrarenal manifestations may precede renal disease
11-18% at presentation & 80% over the course
mild focal & segmental glomerulonephritis with minimal
haematuria & little dimunition of GFR
tofulminant,diffuse,necrotizing &crescentic
glomerulonephritis(RPGN) leading within days to wks to
oligoanuria &dialysis
37. If untreated mean survival is 5 months ;
Chronic renal failure in 42% despite treatment ;
Urine microscopy most useful tool ;
Presence of RBC casts 100% positive predictive value
for glomerulonephritis ;
Fulminant WG - can manifest as pulmonary renal
syndrome ( alveolar haemorrhage & RPGN)
Accounts directly or indirectly for most of the
mortality in this disease
38. PATHOLOGY:
Focal ,segmental glomerulonephritis
Fibrinoid necrosis & proliferative changes
Epiithelial crescents
Sclerotic lesions
Vasculitis – focal in 5-10%
Granulomatous changes –only in 3-20%
Immune complex deposition unusual (pauci
immune)
The degree of renal failure & serum creatinine do not
always correlate with pathological features
44. ANCA & WG :
1985 – Vander woude & colleagues – first to suggest
an association between ANCA & wegener’s
Most likely to be positive in pts with triad disease
that is active & untreated
- PR3 ANCA -sensitivity –active disease – 90%
remission -40%
-specificity - > 95%
High titre ANCA + PR3/MPO specific assay
with high pretest probability is sufficient to diagnose
even in the absence of tissue confirmation
45. Regarding monitoring disease activity,
A substantial no of pts with rise in ANCA titre did not
flare;hence rise in ANCA titre should not be the sole
basis for therapeutic decision making
It was rare to see a flare in the absence of increased
ANCA-strong negative predictive value
46. TREATMENT
CYCLOPHOSPHAMIDE + GLUCOCORTICOIDS :
complete remission in 75 % of patients
Cyclophosphamide
– oral ; 2mg/kg/d
- monitor leucocyte count (>3,000)/µl
- S/e – haemorrhagic cystitis(30%);bladder
cancer(6%);myelodysplasia(2%); infertility
-comtinued for 1 yr after the induction of complete
remission ,taper &discontinue
47. Glucocorticoids :
-Oral;prednisone 1 mg/kg/d initially(1mth);then
alternate day schedule ;taper&discontinue
- S/E –
diabetes,cataract,infections,osteoporosis;cushingoid
features
- IV pulse methyl prednisolone (1g/d for 3 days )
especially for severe cases
• 50% of remissions are later associated with one or
more relapses
48. Maintenance
Methotrexate – start at 0.3mg/kg single weekly dose
- till 2 yrs past remission
Azathioprine- 2mg/kg/day
Mycophenolate mofetil – 1000mg twice a day
49. OTHERS:
Methotrexate induction for non severe disease
Rituximab
TMP-SMX(upper airway disease)
Organ specific treatment
- isolated sinus or joint or skin disease
- subglottic stenosis & endobronchial stenosis
