Patients are classified as G1-G5 based on the eGFR and A1-A3 based on the ACR albumincreatinine ratio as detailed below. Almost all patients with stages G1 and G2 CKD can be appropriately managed in primary care.
We recommend that CKD is classified based on cause GFR category and albuminuria category CGA1B 122.
Ckd staging proteinuria. The IRIS AKI Grading system and the IRIS CKD Staging and Treatment guidelines are works in progress that will be amended and updated as further information becomes available. Assign cause of CKD based on presence or absence of systemic disease and the location within the kidney of observed or. Measurement of ACR forms the basis of the NICE grading system for CKD see CKD stages.
Albuminuria reflecting glomerular damage is usually measured but non-albumin proteinuria NAP reflecting tubular damage may be important. Below this level the conversion is non-linear. 113 Apply a correction factor to GFR values estimated using the CKDEPI creatinine equation for people of African-Caribbean or African family origin multiply eGFR by 1159.
Proteinuria assessment is key in investigating chronic kidney disease CKD but uncertainty exists regarding optimal methods. Identify cause of CKD C Assign GFR category G Assign albuminuria category A Collectively referred to as CGA Staging Assign GFR category as follows. What to do about it.
We recommend that IRIS CKD Stage 1 patients with persistent proteinuria UPC 05 for dogs or 04 for cats are not only monitored and thoroughly investigated but also receive standard treatment for proteinuria as currently recommended for IRIS CKD Stages 2 to 4. A PCR of 100 or ACR of 70 is approximately equal to 1g of protein per 24 hr. 12 Staging of CKD 121.
CKD is classified based on the eGFR and the level of proteinuria and helps to risk stratify patients. The principal aim is to identify individuals at risk of progressive renal disease. New 2014 114 In people with extremes of muscle mass for example in bodybuilders people who have had an amputation or people with muscle wasting disorders interpret eGFRcreatinine with caution.
Biopsy-proven chronic glomerulonephritis most of these patients will have microalbumuria or proteinuria andor haematuria patients found to have a GFR of 60-89 mLmin173 m2 without one of these markers should not be considered to have CKD and should not be subjected to further investigation unless there are additional reasons to do so 1. However substantial research efforts are still needed to develop treatment strategies that may help the vast majority of CKD patients who eventually develop ESKD via mechanistic pathways other than proteinuria. The CKD staging and management outlined below is predicated on stable renal function.
Methods In this prospective cohort study 1138 newly visiting stage G2G5 CKD patients were stratified into normal-range and abnormal. Background Although lower estimated glomerular filtration rate eGFR and higher proteinuria are high risks for mortality and kidney outcomes the prognosis of chronic kidney disease CKD in patients with normal-range proteinuria remains unclear. To diagnose CKD two or more blood tests are required at least 90 days apart.
GFR categories in CKD Category GFR mlmin173 m2 Terms G1 90 Normal or high G2 60-89 Mildly decreased G3a 45-59 Mildly to moderately decreased G3b 30-44 Moderately to severely decreased G4 15-29 Severely decreased G5. If risk factors for CKD repeat eGFR in 12 months eGFR 60 and ACR 30-69 See Box 2 Management in Primary Care Stages 3A 3B eGFR 30 and 60 ACR 30 – 69 No haematuria See Box 2 Management in. A person with an eGFR of 25 mlmin173 m2 and an ACR of 15 mgmmol has CKD G4A2.
Maintaining a high degree of attention in the care of CKD patients with proteinuria is fundamental to effectively retard progression toward kidney failure. Recently we have added guidelines on Grading Acute Kidney Injury AKI and the results of the IRIS Canine Proteinuria Consensus Project have been published online. For quantification and monitoring of higher levels of proteinuria eg.
We recommend that IRIS CKD Stage 1 patients with persistent proteinuria UPC 05 for dogs or 04 for cats are not only monitored and thoroughly investigated but also receive standard treatment for proteinuria as currently recommended for IRIS CKD Stages 2 to 4. ACR 70 mgmmol PCR may be preferable. Chronic Kidney Disease CKD Algorithm Page 5 Management Stages 1 2 eGFR 60 and ACR 30 If no other risk factors for CKD consider normal.
