History and conception of problem
• The conception was developed at the beginning of XXI century by U.S. National Kidney Foundation (National Kidney Foundation) and published in 2002. It’s development was continued by experts from the European Dialysis and Transplant Association (ERA-EDTA) and KDIGO (Kidney Desease: Improving Global Outcomes)
• The purpose of the conception:
- early detection of kidney disease - slowing down the progression of kidney disease - reduction the risk of cardiovascular complications - prevention of kidney lesions - the use of common criteria and universal classification - the use of common terminology

Importance of the problem
The high prevalence of CKD in the world:
1-5 stage of CKD - 12-15% of the population
3-5 stage of CKD - 6-8 % of the population

Importance of the problem
Renal mortality in patients with kidney disease is low.
Cardiovascular pathology as a major factor of patient’s death is ignored.

The main markers of kidney damage, suggestive of the
presence of CKDmarker notes
Albuminuria / proteinuria persistent increasing in urinary albumin excretion greater than 10 mg/day (10 mg albumin/g creatinine) – see recommendation
Persistent changes of the urinary sediment
hematuria, cylindruria, leykotsituriya (piura)
Changes of renal imaging studies
anomalies of the kidney cysts, hydronephrosis, resizing kidneys, etc.
Changes of of blood and urine composition
changes in serum and urinary electrolyte concentration, impaired HGA and others, including the characteristic of the "tubular dysfunction syndrome" (Fanconi's syndrome, renal tubular acidosis, Bartter's syndrome and Gitelman, nephrogenic diabetes insipidus, etc.)
Persistent decrease of GFR less than 60 mL/min/1,73m2
in the absence of other markers of kidney damage
Morphological changes of the lifetime nephrobiopsy
should be taken into account the signs of “chronization” (sclerotic changes of kidneys, changes of membranes, etc.)

Terminology
• CKD - the common notion reflecting the presence of common risk factors of development and progression of different nephropathy.
• The diagnosis of CKD is based on the presence of markers of kidney damage and/or GFR < 60 ml/ min for at least 3 months.
![Page 12: 8-1. Progression of CKD to CRF. Vladimir Dlin (eng)](https://reader033.vdocuments.us/reader033/viewer/2022061212/547b38a6b4af9ff50a8b45ea/html5/thumbnails/12.jpg)

Estimation of GFR
• estimation of GFR in general clinical practice (outpatient) will be based of calculation formulas (eGFR), including gender, age, the patient and the concentration of creatinine in serum
• clearance methods of GFR’s determination will be used at the hospital
![Page 14: 8-1. Progression of CKD to CRF. Vladimir Dlin (eng)](https://reader033.vdocuments.us/reader033/viewer/2022061212/547b38a6b4af9ff50a8b45ea/html5/thumbnails/14.jpg)
Methods of GFR’s estimation
• Simple ways to calculate GFR based on measurements of serum parameters without hour urine collection:
1. Schwart’s formulas 2. Formulas of Cockroft DW., Gault MH.
3. MDRD (Modification of Diet in Renal Disease)4. CKD-EPI method eGFR (the most suitable in the clinical practice)
Levey AS. et al., 2000
![Page 15: 8-1. Progression of CKD to CRF. Vladimir Dlin (eng)](https://reader033.vdocuments.us/reader033/viewer/2022061212/547b38a6b4af9ff50a8b45ea/html5/thumbnails/15.jpg)
eGFR in children on the basis of serum creatinine and growth
(according to Schwartz)
• GFR (ml/min/1,73m2)= [0,0484*х Height (сm)]/Scr (mmol/l)
*k= 0,0616 for boys >13 years

Albuminuria
• Albuminuria (normal < 10 mg/day) – integral sign of CKD
[A. Smirnov et al., 2010] and represents: - increased permeability of cell membranes (size-selectivity, the charge-selectivity);
- transport changes in the proximal tubule;- increased hemodynamic burden on the glomerules;- presence of systemic and renal endothelial dysfunction;- the degree of glomerular/interstitial sclerosis due to glomerular and tubular transport protein disturbances and subsequent activation of profibrotic cytokines
• Albuminuria – risk factor of total and cardiovascular mortality, ESRD, acute kidney injury and progression of CKD
![Page 19: 8-1. Progression of CKD to CRF. Vladimir Dlin (eng)](https://reader033.vdocuments.us/reader033/viewer/2022061212/547b38a6b4af9ff50a8b45ea/html5/thumbnails/19.jpg)

Primary prevention of CKD
is the elimination or minimization of the risk factors for its development:
• clinical supervision of patient from high-risk group;
• the control of modifiable risk factors of development and progression of CKD;
• control of GFR and albuminuria.
![Page 31: 8-1. Progression of CKD to CRF. Vladimir Dlin (eng)](https://reader033.vdocuments.us/reader033/viewer/2022061212/547b38a6b4af9ff50a8b45ea/html5/thumbnails/31.jpg)
Secondary prevention of CKD
• slowing the progression of CKD (renoprotection)
• preventing the development of cardiovascular disease (cardioprotection)
![Page 32: 8-1. Progression of CKD to CRF. Vladimir Dlin (eng)](https://reader033.vdocuments.us/reader033/viewer/2022061212/547b38a6b4af9ff50a8b45ea/html5/thumbnails/32.jpg)

CHRONOTHERAPY
ABPM allows:
to identify the peaks of blood pressure rises
to calculate: Т/Р - duration of antihypertensive action of the drug
N/D - uniformity of drug’s action in the daytime and night hours
IND - uniformity of drug’s action during a day
to optimize therapy
to reduce the risk of target organ’s damage

CHRONOTHERAPY (Nephrology department of Research Institute of Pediatrics & Children surgery, Moscow, Russia)
• Hypotensive therapy of capoten without individual choice of time giving was effective in 57% of children with glomerulonephritis (n = 13).
• The uniformity of the drug’s action during the daytime and nighttime periods was achieved in 45% of children. The uniformity of drug’s action during the day was seen in <25% and a sufficient duration of antihypertensive action of the drug - in 33% of children.

ConclusionPreventing initiation and progression of CKD:
• correction of common modifiable risk factors for the development and progression of renal and cardiovascular disease;
• primary and secondary prevention of CKD (factors increasing susceptibility to CKD, factors of initiation of CKD and factors of progression of CKD);
• nephroprotective and cardioprotective early therapy;
• SMBP control
