CHAPTER 8: RENAL DISEASE Flashcards
(108 cards)
Deposition of immune complexes, in conjunction with streptococcal Infection, on the glomerular membrane
Acute or Post-streptococcal
Glomerulonephritis
Deposition of immune complexes from systemic immune disorders on the glomerular membrane
Rapidly Progressive Glomerulonephritis
Attachment of a cytotoxic antibody formed during viral respiratory infections to glomerular and alveolar
basement membranes
Goodpasture’s Syndrome
Binding of antineutrophilic cytoplasmic antibody to neutrophils in vessel walls
Wegener’s Granulomatosis
Disruption of vascular integrity
following viral respiratory infections
Henoch-Schonlein Purpura
Deposition of IgA on the glomerular membrane resulting from increased levels of serum IgA
IgA Nephropathy
Thickening of the glomerular membrane following IgG immune complex deposition associated with systemic disorders
Membranous Glomerulonephritis (MGN)
Type of MPGN that displays increased cellularity in the subendothelial cells of the mesangium (interstitial area of Bowman capsule), causing thickening of the capillary walls
Type 1 Membranoproliferative glomerulonephritis (MPGN)
Type of MPGN that displays extremely dense deposits in the glomerular basement membrane, tubules, and Bowman capsule
Type 2 Membranoproliferative glomerulonephritis (MPGN)
Type of MPGN that is characterized by both subepithelial and subendothelial deposits
Type 3 Membranoproliferative glomerulonephritis (MPGN)
Refers to a sterile, inflammatory process that affects the glomerulus and is associated with the finding of blood, protein, and casts in the urine
Glomerulonephritis
Marked by the sudden onset of symptoms consistent with damage to the glomerular membrane
Acute glomerulonephritis (AGN)
Symptoms usually occur in children and young adults after respiratory infections caused by certain strains of group A β-hemolytic streptococci that contain M protein in the cell wall
Acute glomerulonephritis (AGN)
Primary urinalysis findings include marked hematuria, proteinuria, and oliguria, accompanied by red blood cell (RBC) casts, dysmorphic RBCs, hyaline and granular casts, and white blood cells (WBCs)
Acute glomerulonephritis (AGN)
These are a hallmark characteristic of acute glomerulonephritis
RBC casts
Formerly called Wegener granulomatosis
Granulomatosis with polyangiitis (GPA)
This autoantibody can be detected in a patient’s serum
Antiglomerular basement membrane antibody
Initial laboratory results are similar to AGN but become
more abnormal as the disease progresses, including protein levels that are markedly elevated and glomerular filtration rates
that are very low
Rapidly Progressive (or crescentic) Glomerulonephritis (RPGN)
Key to the diagnosis of GPA is the
demonstration of?
Antineutrophilic cytoplasmic antibody (ANCA) in the patient’s serum
If the neutrophils are fixed in ethanol, the antibodies form a perinuclear pattern which is called?
p-ANCA
This includes incubating the patient’s serum with either ethanol or formalin/formaldehyde-fixed neutrophils and examining the preparation using indirect immunofixation to detect the serum antibodies attached to the neutrophils
ANCA for GPA
This disease occurs primarily in children after upper respiratory infections.
Henoch-Schönlein Purpura
When the neutrophils are fixed with formalin/formaldehyde, the pattern is granular
throughout the cytoplasm and is referred to as
c-ANCA
Cellular proliferation affecting the capillary walls or the glomerular basement membrane
Membranoproliferative Glomerulonephritis
