CKD - Melani Flashcards
What is CKD ?
Progressive loss of nephrons resulting in
permanent compromise of renal function with GFR
<60ml/min/1.73m2 for 3+ months with or w/o
evidence of kidney damage.
What is ESRD?
GFR <15ml/min/1.73m2 or need for renal replacement therapy such as dialysis or transplant.
What are the GFR and Albumin class in low risk KDIGO CKD ?
GFR class G1 or G2 + Albumin class A1
What are the GFR and Albumin class in moderate risk KDIGO CKD ?
*GFR class G3a + Albumin class A1
* GFR class G1 or G2 + Albumin class A1
What are the GFR and Albumin class in high risk KDIGO CKD ?
G3b + A1 / G3a + A2 / G1 or G2 + A3
What are the GFR and Albumin class in very high risk KDIGO CKD ?
G3a + A3/ G3b + A2 or A3/ G4 or G5 + Any Albumin category
What are GFR rates classification of KDIGO ?
G1= GFR > or = to 90 ( normal or high)
G2= GFR 60-89 ( mild decrease)
G3a= GFR 45 to 59 ( Mild to moderate decrease)
G3b = GFR 30 to 44 ( Moderate to severe decrease)
G4= GFR 15 to 29 ( severe decrease)
G5= GFR < 15 ( very severe decrease)
What are albumin level classification of KDIGO ?
A1= normal to mildly increased ( 30 mg/g or 3 mg/mMol)
A2= Moderate increase ( 30 to 300 mg/ gm)
A3= severe increase > 300 mg/ gm.
What are the causes of CKD ?
- Diabetic nephropathy (38%)
- Hypertensive nephropathy (25%)
- Glomerulonephritis (14%)
– IgA nephropathy - Adult polycystic kidney disease (PCKD, 5%)
- Tubulointerstitial nephropathy
- Obstructive nephropathy
- Chronic pyelonephritis
What are the risk factors for CKD ?
- Diabetes, Hypertension and Vascular disease
- Heart failure, Liver failure and Obesity
- Previous AKI
- Family history and Older age
- HIV and Malignancy
- African ethinicity
What is the symptomatology of CKD ?
Asx until late Stage 4 or Stage 5. It is found on routine blood tests or screening in at risk patient groups. To call it CKD Reduced GFR must persist to 3 months for diagnosis.
What is the advanced presentation of CKD ?
– Fatigue, swelling
– Anorexia, vomiting
– Symptoms of anaemia
– Anuria
– Changes to mental status, seizures
What are the signs of CKD ?
No signs until stage 4 or 5. Later stages may present with:
– Anaemia
– Oedema
– Uraemia
* Encephalopathy, pericarditis
What should be the evaluation approach in CKD ?
– Screen for CKD risk factors.
– Screen for causes of AKI
* Clinical examinatio: BP, Fundoscopy (diabetic or
hypertensive retinopathy)
– Cardiovascular exam and peripheral pulses
– Signs of uraemia and fluid overload
What are the diagnostic investigations for staging CKD ?
- Urea and Creatinine
- Electrolytes: Na+, K+
- eGFR to stage disease
- Dipstick urinalysis
