Glomerulonephritis Flashcards
What is Glomerulonephritis
Inflammation of Glomerulus
Glomerulonephritis is responsible for how much end stage kidney disease
15%
Glomerulonephritis classified based on
kidney biopsy findings
Glomerulonephritis features
Haematuria
Proteinuria
Hypertension
Renal Impairment
Nephritic State
Active Urine Sediment: Haematuria, Dysmorphic RBCS, Cellular Casts
Hypertension
Renal Impairment
Nephrotic Syndrome Features (4)
Oedema
Nephrotic Range Proteinuria >3.5g/day or 350mg/mmol creatinine
Hypoalbuminaemia: Serum Albumin <35g/L
Dyslipidaemia
What is nephrotic range of proteinuria
> 3.5g/day or 350mg/mmol creatinine
Hypoalbuminemia is classified as
Serum Albumin <35g/L
Proliferative Glomerulonephritis classified as
Excessive numbers of cells in glomeruli. These include infiltrating leucocytes
Non Proliferative Glomerulonephritis classified as
Glomeruli look normal or have areas of scarring. They have normal numbers of cells
Which diseases classified as Non Proliferative Nephrotic Glomerulonephritis
Minimal Change Disease
Membranous Neuropathy
FSGS
Which diseases classified as Proliferative Nephrotic Glomerulonephritis
IgA Nephropathy
Lupus Neuprhtis
Which diseases classified as Proliferative Nephritic Glomerulonephritis
Post Infectious GN
ANCA Associated GN
Commonest cause of Glomerulonephritis
IgA Nephropathy
IgA Nephropathy characterised by
IgA deposition in the mesangium and mesangial proliferation.
IgA Nephropathy most common in
2nd and 3rd decade of life with males more commonly affected.
IgA Nephropathy can progress to
end stage kidney disease or halving eGFR at 10 years
Presentation of IgA Nephropathy
Microscopic haematuria.
Micoscopic haematuria + proteinuria
Nephrotic syndrome
IgA crescentic glomerulonephritis
Post Streptoccal Glomerulonephritis follows
10-21 days after throat or skin infection
Post Streptoccal Glomerulonephritis commonly associated with
Lancefield Group A Streptocci
Post Streptoccal Glomerulonephritis genetic predisposition
HLA-DR, -DP, -DP.
Anti GBM Disease characterised by
Circulating Anti GBM
Related to Crescentic Glomerulonephritis
Anti GBM Disease Presentation
Nephritis (anti-GBM glomerulonephritis)
Nephritis+ lung haemorrhage (Goodpasture’s syndrome).
Anti GBM Disease Peaks
Two peaks: 3rd decade and 6th/7th decade.
Anti GBM Disease Diagnosis
demonstrating anti-GBM antibodies in serum and kidney
Anti GBM Disease Treatment
aggressive immunesuppression: steroid, plasma exchange, and cyclophosphamide.
How does Proliferative Glomerulonephritis present
with nephritic state
Haematuria + variable proteinuria + hypertension +/- renal impairment
Proliferative Glomerulonephritis can cause
rapid decline needing dialysis
To save nephrons in Proliferative Glomerulonephritis diagnosis
Clinical suspicion + immunology screen + renal biopsy
Nephrotic Syndrome Management
Treat oedema: salt and fluid restriction and loop diuretics.
Hypertension: use Renin-Angiotensin-Aldosterone-blockade.
Reduce risk of thrombosis: Heparin or Warfarin.
Reduce risk of infection e.g. pneumococcal vaccine.
Treat dyslipidemia e.g. statins.
