Q

typically presents with hematuria, edema, often hypertension and
some proteinuria.

Study These Flashcards
A

Glomerulonephritis

24
Q

How is proteinuria quantified?

Study These Flashcards
A

By age.

Spot protein: Infants >0.5, Children > 0.2, Non-nephrotic 0.2-2, Nephrotic >2.

25
3 common causes causes of glomerulonephritis.
Post streptococcal/IGN IgA nephropathy HSP
26
has a low C3 which returns to normal in 6-8 weeks.
Post-streptococcal glomerulonephritis
27
Post-streptococcal glomerulonephritis usually only requires
supportive management like antihypertensive meds, Salt and fluid restriction diuretic, and rarely dialysis.
28
The prognosis for post-streptococcal glomerulonephritis is
good
29
Can last for 1 year
Microscopic hematuria
30
Can last for 6 mo-1 yr
proteinuria
31
normalizes w/ in 6-8 weeks
C3
32
Resolves w/ in days
Gross hematuria
33
Normal C3, recurrent hematuria, Less than 1 week after URI.
IgA nephropathy
34
C3 decreased, isolated episode of hematuria, 1-2 weeks after URI/pharyngitis, 3-6 weeks after impetigo.
PSGN
35
Petechia or purpura on lower ext and gluteal region, classically have swelling in hands and feet, abdominal pain, nausea and vomiting. Joint inflammation. Need a urine dip to look for protein and blood.
HSP
36
3 major causes of postnatal hydronephrosis.
Transient, Vesicoureteral reflux (VUR), Obstruction.
37
MC cause of hydronephrosis and goes away by the age of 2.
Transient
38
Least common cause of hydronephrosis.
Obstruction
39
How is hydronephrosis monitored?
Ultrasounds
40
How do they diagnos reflux or obstruction?
VCUG and renal scan (how a diuretic is excreted)
41
Which hydronephrosis is associated with UTI?
Vesicoureteral Reflux
42
Children with reflux or obstruction need to be followed for progression of
chronic kidney disease
43
periorbital edema is associated with what?
Nephrotic syndrome
44
defined by proteinuria, hypoalbuminemia, edema and hyperlipidemia.
Nephrotic syndrome
45
the most common cause of nephrotic syndrome in children.
Minimal change disease
46
The primary treatment for minimal change nephrotic syndrome is
steroids. (prednisone)
47
most common form of polycystic kidney disease
Autosomal dominant polycystic kidney disease (ADPKD)
48
In autosomal dominant polycystic kidney dz the most common mutation is in what gene?
PKD 1 gene.
49
What is the treatment for ADPKD?
Focused on slowing the progregression. Proteinuria management, HTN management, no caffeine, keeping hydrated.
50
This can give rise to HTN in children.
Renal artery stenosis. | Need renal ultrasound w/ doppler.
51
Renal artery stenosis can be diagnosed sometimes by
Renal ultrasound with doppler.
52
Renal artery thrombosis can be seen in newborns with
umbilical artery catheters
53
This can present a flank pain, hematuria, HTN, and AKI.
Renal artery thrombosis
54
Renal vein thrombosis can be seen most commonly in
Nephrotic syndrome and kidney transplant
55
defined by microangiopathic hemolytic anemia, thrombocytopenia and acute kidney injury
Hemolytic Uremic Syndrome (HUS)
56
HUS is often caused by
E. Coli | Present with bloody diarrhea and abdominal pain.
57
What is the Tx for Typical HUS?
Supportive care. If acute, the kidney injury can progress to needing dialysis.
