Хроническая Болезнь Почек: Функция Почек и Показатели Здоровья

Хроническая болезнь почек затрагивает миллионы людей во всём мире. Раннее выявление через регулярные анализы крови крайне важно.

Prevalence:15% of U.S. adults (37 million people)

Что Такое Хроническая Болезнь Почек?

Хроническая болезнь почек (ХБП) — это постепенная потеря функции почек со временем. Почки фильтруют отходы и избыток жидкости из крови.

Ключевые Почечные Показатели

СКФ (Скорость Клубочковой Фильтрации) — самый важный показатель: ≥90 — норма, 60-89 — 2 стадия, 30-59 — 3 стадия, 15-29 — 4 стадия, <15 — 5 стадия.

Факторы Риска

Основные факторы риска включают диабет, высокое давление, сердечные заболевания и семейную историю.

Профилактика и Защита Почек

Защитите почки, контролируя давление и сахар в крови, поддерживая гидратацию и проходя регулярные обследования.

🌍 Regional Context

Хроническая болезнь почек — растущая глобальная проблема здравоохранения.

В России около 13% взрослых имеют ту или иную степень ХБП.

❓ Frequently Asked Questions

Какая СКФ указывает на болезнь почек?

СКФ ниже 60 мл/мин/1.73м² в течение 3+ месяцев указывает на хроническую болезнь почек.

📊 Ключевые Метрики для Мониторинга

Эти показатели здоровья необходимы для диагностики и мониторинга chronic kidney disease (ckd):

🔬 Diagnostic Criteria

Healthcare providers use these thresholds to diagnose and classify chronic kidney disease (ckd):

MetricThresholdClassification
eGFR≥90 mL/minStage 1 (Normal/High)
eGFR60-89 mL/minStage 2 (Mild decrease)
eGFR45-59 mL/minStage 3a (Mild-Moderate)
eGFR30-44 mL/minStage 3b (Moderate-Severe)
eGFR15-29 mL/minStage 4 (Severe)
eGFR<15 mL/minStage 5 (Kidney Failure)

Note: Diagnosis requires clinical evaluation. These criteria are for reference only.

⚠️ Risk Factors

Diabetes
High blood pressure
Heart disease
Family history
Age over 60
Obesity
Smoking

🔴 Potential Complications

If left unmanaged, chronic kidney disease (ckd) may lead to:

Fluid retention
Potassium buildup
Cardiovascular disease
Weak bones
Anemia
End-stage kidney disease

✅ Prevention Strategies

1Control blood sugar
2Manage blood pressure
3Maintain healthy weight
4Avoid NSAIDs overuse
5Stay hydrated
6Regular kidney function tests

🧬 Understanding Chronic Kidney Disease (CKD)

Medical Literature

CKD involves progressive nephron loss from various causes. Diabetes and hypertension account for 60%+ of cases, causing glomerular damage. As nephrons are lost, remaining ones hypertrophy and hyperfiltrate, leading to further damage. Proteinuria accelerates progression through tubular toxicity. Declining kidney function causes metabolic abnormalities: uremia, anemia (reduced EPO), bone disease (phosphorus retention, vitamin D deficiency), and cardiovascular complications. The kidneys' role in regulating blood pressure, electrolytes, and acid-base balance makes CKD a systemic disease.

📈 Epidemiology & Statistics

CDC / WHO Data
Global Prevalence
850 million people worldwide have CKD
U.S. Prevalence
37 million Americans (15%) have CKD
Trend
Increasing due to diabetes and aging population
Demographics
Higher in Black and Hispanic populations, increases sharply with age
Data from CDC National Health Statistics, WHO Global Health Observatory, and peer-reviewed epidemiological studies.

🔍 Screening Recommendations

KDIGO/NKF
Recommended Frequency: Annually for those with diabetes, hypertension, or risk factors

Recommended Tests

  • eGFR calculation from serum creatinine
  • Urine albumin-to-creatinine ratio (UACR)
  • Blood pressure measurement
  • Electrolyte panel as CKD progresses
💡 Note: Screening recommendations may vary based on individual risk factors. Consult with your healthcare provider for personalized screening guidance.

💊 Treatment Approaches

Clinical Guidelines

Blood Pressure Control

1

Target <130/80, ACE inhibitors/ARBs preferred

Effectiveness: Slows progression by 30-40%

SGLT2 Inhibitors

2

Kidney protection beyond glucose control

Effectiveness: Reduces kidney failure risk by 30-40%

Dietary Management

3

Protein and sodium restriction as appropriate

Effectiveness: May slow progression

Dialysis/Transplant

4

Renal replacement therapy for ESRD

Effectiveness: Life-sustaining for kidney failure
⚠️ Medical Disclaimer: Treatment decisions should be made with healthcare providers based on individual circumstances, preferences, and the latest clinical evidence.
