A CASE REPORT

A 21-year-old woman presented to her local hospital in July

2006 with a one week history of flue-like illness chest

pain dyspnoe and blood-streaked sputum

Chest radiography showed bilateral patchy lung opacities

interpreted as possible atypical pneumonia which

regressed after treatment with azythromycin

No results of urinalysis

The patient was free of symptoms until the end of October

2006

OCTOBER 2006

Haemoptysis dyspnoe generalized oedema

Radiologic findings consistent with diffuse alveolar

haemorrhage

Severe anaemia

Nephrotic syndrome with erythrocyturia

Normal renal function

Urinalysis

proteinuria 63 gd erythrocyturia 209 leukocyturia 78 (x10⁶L)

Blood tests

blood urea nitrogen 120 mgdL (43 mmolL)

serum albumin 23 gdL (23 gL)

haemoglobin 92 gdL (92 gL)

Immunoserology

anti-GBM antibodies negative by standard ELISA

Hep ndash 2 ANA 1320 (speckled pattern)

Other immunoserology negative also in further follow-up

ENA anti-dsDNA anticardiolipin IgG and IgM

THE DIAGNOSIS

Anti-GBM glomerulonephritis with concomitant immune

complex membranous and proliferative

glomerulonephritis (mesangioproliferative and segmental

endocapillary proliferative pattern)

TREATMENT (NOVEMBER 2006 ndash JULY 2007)

Plasmapheresis

Metylprednisolone pulses iv

Cyclophosphamide

The symptoms of respiratory insufficiency and haemoptysis

disappeared

Maintenance therapy with metylprednisolone because of

persistent proteinuria

ANA 180

AUGUST 2007

THE FIRST RECURRENCE

Recurrence of nephrotic proteinuria and erythrocyturia no

pulmonary involvement

ANA 1320

AUGUST 2007

THE FIRST RECURRENCE

Immunoserology anti-GBM antibodies negative by standard tests

but positive by more sensitive detection methods

1) ELISA test for IgG subclasses revealed low titre of IgG4 antibodies

2) anti-GBM antibodies positive by IIF on biochips containing purified GP antigen (NC1 domain of alpha 3 collagen IV)

THE SECOND BIOPSY

THE SECOND BIOPSY

THE SECOND BIOPSY

THE SECOND BIOPSY

THE DIAGNOSIS

Anti-GBM glomerulonephritis (1020 ndash 50 crescents)

with concomitant immune complex proliferative

glomerulonephritis (in this biopsy also

membranoproliferative)

Due to SED and SEP deposits it may be classified as

membranoproliferative glomerulonephritis type III

(atypical ndash focal and segmental changes)

TREATMENT

Metylprednisolone

Mycophenolate mofetil (MMF)

In December 2007 nephrotic syndrome remitted but

proteinuria persisted ndash 15 gd (partial remission)

ANA 180

AUGUST 2009

SECOND RECURRENCE

In August 2009 pulmonary involvement with haemoptysis

and radiologic signs of diffuse alveolar haemorrhage

without renal involvement

ANA 1320

Anti-GBM antibodies by standard ELISA were negative but

now positive by indirect immunofluorescence on normal

kidney 110 and on α3 col IV biochip 110

Treatment methylprednisolone pulses and MMF continued

Haemoptysis disappeared

LAST FOLLOW-UP IN DECEMBER 2009

Laboratory results within normal ranges but persistent

proteinuria (12 gd)

December 2009 ndash 2014 She failed to attend subsequent

outpatient appointments and became lost to follow-up

CONCLUSIONS

Classical GP syndrome is monophasic disease clinically

presented as RPGN and histologically characterized by

diffuse crescentic glomerulonephritis without significant

mesangial proliferation

The majority of patients have circulating anti-GBM

antibodies detectable with standard anti-GBM ELISA

OUR PATIENT

bull Not so extensive crescentic GN with normal renal

function only about 50 crescents small to medium

sized with not much glomerular destruction and

necrosis

bull Concurrent immune complex membranous and

proliferative GN (MEZ ENDO and MPGN in the second

biopsy)

CONCLUSIONS

bull Anti-GBM antibodies detected only by more sensitive

methods

bull Persistent proteinuria

bull Recurrent course

CONCLUSION

It is not clear which pathogenetic mechanisms was the

initial the anti-GBM or immune-complex mediated

Both possibilities (case reports and experimentally) initial

disease (anti-GBM or MGN) exposes or changes antigens

of the glomerular basement membranerarr another types of

autoantibodies are formed

In our patient temporal relation can not be determined the

patient had chronic lesions already in the first biopsy

and initial clinical data are lacking

CONCLUSION

The patient had a persistently positive ANA and ANA titres

corresponded with relapses of the disease Whether ANA

have a pathogenetic role in her disease is unclear

The patient did not fulfill criteria for the diagnosis of SLE

Furthermore there were no ldquofull-houserdquo immune

deposits no extraglomerular granular immune deposits

no tubuloreticular inclusions or bdquofingerprintsldquo by EM

However this patient probably had an autoimmune

syndrome associated with the production of more than

one type of antibodies

THE DIAGNOSIS

Anti-GBM glomerulonephritis (1020 ndash 50 crescents)

with concomitant immune complex proliferative

glomerulonephritis (in this biopsy also

membranoproliferative)

Due to SED and SEP deposits it may be classified as

membranoproliferative glomerulonephritis type III

(atypical ndash focal and segmental changes)

TREATMENT

Metylprednisolone

Mycophenolate mofetil (MMF)

In December 2007 nephrotic syndrome remitted but

proteinuria persisted ndash 15 gd (partial remission)

ANA 180

AUGUST 2009

SECOND RECURRENCE

In August 2009 pulmonary involvement with haemoptysis

and radiologic signs of diffuse alveolar haemorrhage

without renal involvement

ANA 1320

Anti-GBM antibodies by standard ELISA were negative but

now positive by indirect immunofluorescence on normal

kidney 110 and on α3 col IV biochip 110

LAST FOLLOW-UP IN DECEMBER 2009

Laboratory results within normal ranges but persistent

proteinuria (12 gd)

December 2009 ndash 2014 She failed to attend subsequent

outpatient appointments and became lost to follow-up

CONCLUSIONS

Classical GP syndrome is monophasic disease clinically

presented as RPGN and histologically characterized by

diffuse crescentic glomerulonephritis without significant

mesangial proliferation

The majority of patients have circulating anti-GBM

antibodies detectable with standard anti-GBM ELISA

OUR PATIENT

bull Not so extensive crescentic GN with normal renal

function only about 50 crescents small to medium

TREATMENT (NOVEMBER 2006 ndash JULY 2007)

Plasmapheresis

Metylprednisolone pulses iv

Cyclophosphamide

The symptoms of respiratory insufficiency and haemoptysis

disappeared

Maintenance therapy with metylprednisolone because of

persistent proteinuria

ANA 180

AUGUST 2007

THE FIRST RECURRENCE

Recurrence of nephrotic proteinuria and erythrocyturia no

pulmonary involvement

ANA 1320

AUGUST 2007

THE FIRST RECURRENCE

Immunoserology anti-GBM antibodies negative by standard tests

but positive by more sensitive detection methods

1) ELISA test for IgG subclasses revealed low titre of IgG4 antibodies

2) anti-GBM antibodies positive by IIF on biochips containing purified GP antigen (NC1 domain of alpha 3 collagen IV)

THE SECOND BIOPSY

THE SECOND BIOPSY

THE SECOND BIOPSY

THE SECOND BIOPSY

THE DIAGNOSIS

Anti-GBM glomerulonephritis (1020 ndash 50 crescents)

with concomitant immune complex proliferative

glomerulonephritis (in this biopsy also

membranoproliferative)

Due to SED and SEP deposits it may be classified as

membranoproliferative glomerulonephritis type III

(atypical ndash focal and segmental changes)

TREATMENT

Metylprednisolone

Mycophenolate mofetil (MMF)

In December 2007 nephrotic syndrome remitted but

proteinuria persisted ndash 15 gd (partial remission)

ANA 180

AUGUST 2009

SECOND RECURRENCE

In August 2009 pulmonary involvement with haemoptysis

and radiologic signs of diffuse alveolar haemorrhage

without renal involvement

ANA 1320

Anti-GBM antibodies by standard ELISA were negative but

now positive by indirect immunofluorescence on normal

kidney 110 and on α3 col IV biochip 110

Treatment methylprednisolone pulses and MMF continued

Haemoptysis disappeared

LAST FOLLOW-UP IN DECEMBER 2009

Laboratory results within normal ranges but persistent

proteinuria (12 gd)

December 2009 ndash 2014 She failed to attend subsequent

outpatient appointments and became lost to follow-up

CONCLUSIONS

Classical GP syndrome is monophasic disease clinically

presented as RPGN and histologically characterized by

diffuse crescentic glomerulonephritis without significant

mesangial proliferation

The majority of patients have circulating anti-GBM

antibodies detectable with standard anti-GBM ELISA

OUR PATIENT

bull Not so extensive crescentic GN with normal renal

function only about 50 crescents small to medium

sized with not much glomerular destruction and

necrosis

bull Concurrent immune complex membranous and

proliferative GN (MEZ ENDO and MPGN in the second

biopsy)

CONCLUSIONS

bull Anti-GBM antibodies detected only by more sensitive

methods

bull Persistent proteinuria

bull Recurrent course

CONCLUSION

It is not clear which pathogenetic mechanisms was the

initial the anti-GBM or immune-complex mediated

Both possibilities (case reports and experimentally) initial

disease (anti-GBM or MGN) exposes or changes antigens

of the glomerular basement membranerarr another types of

autoantibodies are formed

In our patient temporal relation can not be determined the

patient had chronic lesions already in the first biopsy

and initial clinical data are lacking

CONCLUSION

The patient had a persistently positive ANA and ANA titres

corresponded with relapses of the disease Whether ANA

have a pathogenetic role in her disease is unclear

The patient did not fulfill criteria for the diagnosis of SLE

Furthermore there were no ldquofull-houserdquo immune

deposits no extraglomerular granular immune deposits

no tubuloreticular inclusions or bdquofingerprintsldquo by EM

However this patient probably had an autoimmune

syndrome associated with the production of more than

one type of antibodies

disease (anti-GBM or MGN) exposes or changes antigens

of the glomerular basement membranerarr another types of

autoantibodies are formed

In our patient temporal relation can not be determined the

patient had chronic lesions already in the first biopsy

and initial clinical data are lacking

CONCLUSION

The patient had a persistently positive ANA and ANA titres

corresponded with relapses of the disease Whether ANA

have a pathogenetic role in her disease is unclear

The patient did not fulfill criteria for the diagnosis of SLE

Furthermore there were no ldquofull-houserdquo immune

deposits no extraglomerular granular immune deposits

no tubuloreticular inclusions or bdquofingerprintsldquo by EM

However this patient probably had an autoimmune

syndrome associated with the production of more than

one type of antibodies

LAST FOLLOW-UP IN DECEMBER 2009

Laboratory results within normal ranges but persistent

proteinuria (12 gd)

December 2009 ndash 2014 She failed to attend subsequent

outpatient appointments and became lost to follow-up

CONCLUSIONS

Classical GP syndrome is monophasic disease clinically

presented as RPGN and histologically characterized by

diffuse crescentic glomerulonephritis without significant

mesangial proliferation

The majority of patients have circulating anti-GBM

antibodies detectable with standard anti-GBM ELISA

OUR PATIENT

bull Not so extensive crescentic GN with normal renal

function only about 50 crescents small to medium

sized with not much glomerular destruction and

necrosis

bull Concurrent immune complex membranous and

proliferative GN (MEZ ENDO and MPGN in the second

biopsy)

CONCLUSIONS

bull Anti-GBM antibodies detected only by more sensitive

methods

bull Persistent proteinuria

bull Recurrent course

CONCLUSION

It is not clear which pathogenetic mechanisms was the

initial the anti-GBM or immune-complex mediated

Both possibilities (case reports and experimentally) initial

disease (anti-GBM or MGN) exposes or changes antigens
