GP_GU Flashcards
Name 5 key functions of the kidneys
- Vit D metabolism
- Blood volume/ fluid balance
- Makes EPO
- Waste/ toxin/ drug excretion
- Acid-base regulation
What bloods tests can be ordered to assess kidney function
- eGFR
- Creatinine
- U&Es
- Other biochemistry: bicarb, albumin, Ca, alkphos, PTH, phosphate?
What makes up U&Es?
- Sodium
- Potassium
- Urea
- Creatinine
- eGFR?
What urine tests can be done to assess kidney function?
- Albumin: creatinine ratio
2. Urinalysis for proteinuria & haematuria
Which patients are at risk of CKD and need their renal function monitored regularly? (Name 5 risk factors/diseases)
- High blood pressure
- Diabetes
- AKI
- CVS disease i.e. coronary heart disease, HF
- Other conditions that effects kidneys i.e. kidney stones, SLE
- Patients on long term steroids
- Hx of AKI
- Old age (>50)
- Fhx of CKD
What are the DAMN drugs?
Key drugs that can cause AKI:
- Diuretics
- Ace inhibitors
- Metformin
- NSAIDS
Give 5 causes of CKD
Vascular: Htn Infection: Strep glomerulonephritis Trauma Autoimmune: SLE Metabolic: Diabetes, hypercalcaemia Iatrogenic: DAMN drugs - NSAIDs, ace-i Neoplasms Congenital: Alports, PCOS
Give 4 symptoms of CKD
- NB early stages are usually asymptomatic
1. Swollen ankles, hands, feet
2. Puffy face
3. SOB
4. Tiredness
5. Weight loss and poor appetite
6. Muscle cramps
Give 4 signs of CKD
- Pallor
- Htn
- Peripheral oedema
- Pleural effusion
- Proteinuria
- Haematuria
Define CKD stage 1
A normal eGFR ( >90ml/min), but other tests have detected signs of kidney damage
Define CKD stage 2
A slightly reduced eGFR (60-89ml/min), with other signs of kidney damage
Define CKD stage 3a
eGFR of 45-59ml/min
Define CKD stage 3b
eGFR of 30-44ml/min
Define CKD stage 4
eGFR of 15-29ml/min
Define CKD stage 5
eGFR below 15ml/min
4 principles of managing CKD
- Lifestyle advice
- Treat cause
- Manage complications
- Consider renal replacement therapy if disease is severe
List 5 lifestyle advice that can be given to patients with CKD
- Stop smoking
- Lose weight/ exercise regularly
- Eat a balances and healthy diet
- Moderate alcohol intake
- Regulate salt intake
- Avoid NSAIDs i.e. ibuprofen
List 5 complications of CKD
- Anaemia
- Coagulopathy
- Htn leading to LV hypertrophy, HF
- Fluid overload leaning to pulmonary oedema
- Secondary hyperparathyroidism: bone pain and fractures
- Calcium phosphate loading
- Hyperkalaemia
- Acidosis
What drugs an be used to control Htn in CKD?
Ace-i/ARB or Ca channel blockers
What are the BP targets for patients with:
- CKD
- CKD and diabetes
- < 140/90mmHg
2. <130/80mmHg
If acutely fluid overloaded what medication can be given in CKD?
Loop diuretic
What medication can be given in patient with CKD has metabolic acidosis?
Oral bicarbonate supplements
What 3 options make up renal replacement therapy?
- Haemodialysis
- Peritoneal dialysis
- Kidney transplant
