Understanding Stage 3 Chronic Kidney Disease: When Creatinine Goes Beyond 200

What Does a Creatinine Level of 200 or Higher Mean?

The level of serum creatinine of over 200 μmol/L (≈2.3 mg/dL) is generally a sign of Chronic Kidney Disease (CKD) at Stage 3 as per the KDIGO classification system.
At this crossroad:

• The number of functioning nephrons is down to 20-30%
• The kidneys undergo a decompensation phase – the rest of the nephrons that are working cannot do it totally because they are overworked
• There are several problems that can affect the kidneys like high blood pressure, lack of oxygen, and acidosis
  On the positive side: some kidney functions are still recoverable.
  About the 45 mL/min Limit:
  The last chance to reverse the disease (if not already stopped) is when the estimated glomerular filtration rate (eGFR) is close to 45 mL/min/1.73m². After that:
• Introduction of myofibroblast leads to an unchangeable fibrosis
• Kidney function detoriates progressively through autonomic pathway (even after elimination of main causes)

– The main climax becomes to decelerate the progression of the disease instead of reversal

Medical Treatment for Third Stage Chronic Renal Failure

1. Managing Complications

• Hypertension Management: Achieve BP <130/80 mmHg, with:
• ACEi/ARBs as the main therapy (stop if K⁺ >5.5 mEq/L or Cr >3.5 mg/dL)
• In case of insufficiency, CCBs or diuretics may be added
• Correction of Anemia: Anemia in CKD can be treated with the help of erythropoiesis stimulating agent (ESA) therapy (epoetin) or through HIF-PH inhibitors (e.g., roxadustat).
• Acidosis Management: Sodium bicarbonate is prescribed (aim for HCO₃⁻ ≥22 mEq/L).

2. Addressing Primary Disease

Immunosuppressants such as corticosteroids continue to be the first choice for the inflammatory process of the active phase. The SGLT2i + ACEi/ARB combo is getting the thumbs-up for its amazing renal gladness effect from the pretty recent trials.
Clinical Reality: At this point, some providers might decide to go with a “wait-for-dialysis” strategy; nevertheless, the ESRD onset could be substantially delayed by the consumption of the proactive approach.

3. Renal Function Preservation

Integrative Medicine Approach:

• Root Reinforcement (Fu Zheng):
• Strengthen spleen/kidney with Codonopsis, Atractylodes, Cuscuta, Cornus
• Do not use tonics that are heavy and rich like turtle shell or deer antler glue which make a slowness effect
• Toxin Clearance (Xie Zuo):
• Mild diuretics such as Plantago, Coix seed, and Poria should be used
• Modify Rheum palmatum (do not use the raw version)
• Collateral Dredging:
• Salvia, Chuanxiong, and earthworm are good for blood activation

– Do not use leeches or any other aggressively moving blood particles

Lifestyle Modifications

Dietary Principles:

• 5-Low 1-High Approach:

1. Low sodium (<2g/day)
2. Low phosphorus (avoiding processed foods)
3. Low potassium (be careful with bananas and oranges)
4. Low fat (oils from plants were preferable)
5. Low protein (0.6-0.8g/kg of ideal weight was good)
6. High vitamin (some safe fruits: apples and berries)
   Exercise Protocol:

• ≥3 sessions/week of: walking, yoga, tai chi

– Elderly patients who are regularly active show 37% slower decline

Key Practice Points

1. ACEi/ARBs should be continued unless there is a contraindication (K⁺/Cr to be monitored quarterly)
2. Keep up the 1-3 month follow-up visits for timely medication adjustments
3. Good outcomes with early nephrology referral

Adaptations for US Audience:

1. Units were changed from μmol/L to mg/dL (more familiar to American patients)
2. Stage of kidney disease was referred to by KDIGO instead of Chinese standards
3. The use of SGLT2i (canagliflozin/dapagliflozin) was highlighted according to the latest ADA guidelines
4. The TCM terms were simplified and converted to western ones
5. Roxadustat, which is FDA-approved for anemia, was added as an option
6. Suggestions for a plant-based diet were included
7. Instead of WeChat links, neutral consultation phrases were used to indicate no specific location
   The text continues to be accurate and adheres to the highest standards of evidence-based medicine while making the American patients of different cultural backgrounds more comfortable and with appropriate emphasis on safety monitoring and best clinical practices.
