Glomerular Disease (Mcleod) Flashcards
Pathologic proteinuria is equal to _____ or more in 24 hours
150mg
What is the smallest plasma protein
Albumin
Microalbuminuria
30-300mg/day of albumin excreted
Macro albuminuria
> 300mg/day of albumin excreted
Daily excretion fo more than ______ of protein is termed nephrotic range proteinuria
3.5g
What is the gold standard for definitive diagnosis of nephrotic versus nephritic syndrome
biopsy
Common Nephritic Syndrome characteristics
- Hematuria
- RBC casts/dysmorphic RBCs
- Occasional WBCs
- proteinuria <3.5g/day
- Azotemia
- Oliguria
- Edema
- Gradual increase in creatinine
Name the 5 Nephritic Syndromes
- Post Infectious Glomerulonephritis
- IgA nephropathy
- Henoch- Schonlein purpura
- Pauci-immune glomerulonephritis (ANCA-associated)
- Anti-Glomerular Basement Membrane Glomerulonephritis (Goodpasture Syndrome)
What causes Post infectious Glomerulonephritis?
Group A beta hemolytic streptococci
What damages the glomerulus in Post Infectious Glomerulonephritis?
Immune complexes with streptococcal antigen components
How long after the initial strep infection does the glomerulonephritis occur?
1-3 weeks
Describe the UAof Post infectious glomerulonephritis
UA: cola colored urine, RBC casts, proteinuria
What is the classic blood test to identify post infectious glomerulonephritis
ASO titer
Treatment for Post infectious glomerulonephritis
- *Treatment is supportive
1. ACE or ARB
2. Salt restrict
3. Diuretics
Steroids don’t improve outcome
What is the most common primary glomerular disease worldwide?
IgA nephropathy (Berger’s Disease)
When does IgA nephropathy present after a URI or GI infection?
cola colored urine 1-3 days after illness onset
What are the 4 labs you would expect to see in IgA nephropathy?
- Hematuria
- Proteinuria
- Increased IgA levels**
- Complement normal
What is the most unfavorable prognostic indicator for IgA nephropathy?
proteinuria <1g/day
