In medicine, chronic kidney disease is defined as "kidney damage or glomerular filtration rate (GFR) <60 mL/min/1.73 m(2) for 3 months or more, irrespective of cause. Kidney damage in many kidney diseases can be ascertained by the presence of albuminuria, defined as albumin-to-creatinine ratio >30 mg/g in two of three spot urine specimens."[1]
Classification
There are five stages:[1]
- Stage 1 - glomerular filtration rate is 90 ml/min/1.73 m2 or more
- Stage 2 - glomerular filtration rate is 60-89 ml/min/1.73 m2
- Stage 3 - glomerular filtration rate is 30-59 ml/min/1.73 m2
- Stage 4 - glomerular filtration rate is 15-29 ml/min/1.73 m2
- Stage 5 - glomerular filtration rate is less than 15 ml/min/1.73 m2 or on renal dialysis
Etiology/cause
Bilateral renal artery stenosis (RAS) may cause 5% to 15% of cases of chronic kidney disease.[2]
Signs and symptoms
Uremia, "the illness accompanying kidney failure", may have subtle manifestations when the glomerular filtration rate falls below 60 ml/min/1.73 m2 [3]
Treatment
Various drugs have been studied for slowing the progression of chronic kidney disease.[4][5][6]
| Treatment | Setting | Results |
|---|---|---|
| Protein restriction[4] | Diabetic renal disease | relative risk of end stage renal disease or death: |
| Protein restriction[5] | Non-diabetic renal disease | relative risk of renal death: |
| Angiotensin converting enzyme inhibitors[6] | Diabetic renal disease |
Medications
Angiotensin inhibition
Angiotensin can be inhibited with either angiotensin converting enzyme inhibitors[7] or angiotensin II receptor antagonists. These medications can help patients with an elevated creatinine,[8] including those with a creatinine of 1.5 to 5.0 mg per deciliter.[9]
Phosphate binders
Phosphate binders (calcium carbonate 650 mg tabs three times per day by mouth and calcitriol 0.25-0.5 µg once per day) are given once a patient has Stage 3 disease in order to prevent secondary hyperparathyroidism.
Allopurinol
A single randomized controlled trial found that giving allopurinol to hyperuricemic patients with chronic kidney disease had a relative risk ratio of 0.35 in the prevention of "significant deterioration in renal function and dialysis dependence."[10]
