The treatment goals for chronic kidney disease are to slow the deterioration of kidney function, control symptoms, prevent complications, and improve the quality of life for patients. Treatment strategies should be tailored based on the stage of the disease, the overall health status of the patient, and personalized needs, typically involving a comprehensive plan that includes medications, non-pharmacological therapies, and lifestyle adjustments.
Early treatment can effectively delay the progression of the disease to end-stage renal failure, making early diagnosis and proactive management crucial. Physicians will adjust the intensity of treatment based on the estimated glomerular filtration rate (eGFR) and the level of metabolic waste accumulation. Treatment must also monitor key indicators such as blood pressure, blood sugar, and proteinuria, and intervene for complications such as anemia and mineral metabolism disorders.
The treatment process emphasizes patient participation, including regular follow-ups, self-monitoring, and changes in health behavior. The medical team may include nephrologists, dietitians, and nurses who work together to develop individualized treatment plans. Patients with end-stage kidney disease need to assess the feasibility of dialysis or kidney transplantation and prepare accordingly both physically and mentally.
Controlling blood pressure is key to slowing the deterioration of kidney function. Studies show that the target blood pressure is usually set below 120/80 mmHg, requiring a combination of antihypertensive medications and lifestyle adjustments. Management of proteinuria is also crucial, as proteinuria indicates glomerular damage, necessitating the use of ACE inhibitors or ARBs to reduce urinary protein excretion.
For diabetic patients, strict blood sugar control can reduce the risk of further kidney damage. Research indicates that hemoglobin A1c (HbA1c) should be maintained below 7%, in conjunction with insulin or oral hypoglycemic agents. Additionally, a low-protein diet can reduce the filtering burden on the kidneys, with a recommended daily protein intake of 0.8 grams per kilogram of body weight.
Anemia treatment often involves erythropoietin (EPO) and iron supplements to improve tissue oxygen supply. Metabolic acidosis requires bicarbonate supplementation, while hypercalcemia and hyperphosphatemia necessitate limiting phosphate intake and using phosphate binders. Symptoms of swelling can be controlled with diuretics to maintain fluid balance, but electrolyte concentrations must be closely monitored to prevent hypotension.
Cardiovascular protective measures include the use of statins for lipid lowering and regular monitoring of cardiac function. Patients with end-stage kidney disease may require dialysis, and the suitability of vascular access must be assessed before choosing between hemodialysis and peritoneal dialysis, explaining the pros and cons of both options.
First-line medications include angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin receptor blockers (ARBs), which can reduce proteinuria and protect the glomeruli. Common medications include Losartan and Irbesartan, with regular monitoring of serum creatinine and potassium levels required.
Metabolic acidosis is common in end-stage kidney disease and can be managed with sodium bicarbonate to buffer blood pH. Phosphate binders such as calcium carbonate and Sevelamer should be taken before meals to bind intestinal phosphate ions. Active vitamin D3 (Alfacalcidol) can improve calcium and phosphate metabolism, but blood calcium levels must be monitored to prevent hypercalcemia.
For anemia treatment, erythropoietin (EPO) should be used in conjunction with iron supplements, and ferritin and transferrin saturation should be measured regularly. New oral medications like Roxadustat can stimulate endogenous EPO production, potentially reducing the frequency of injections.
Hemodialysis requires establishing vascular access, such as an arteriovenous fistula or central venous catheter. The treatment frequency is usually three times a week for four hours each time, with attention to the risks of infection and fluid overload. Peritoneal dialysis uses the peritoneum as a semipermeable membrane, requiring patients to perform exchanges daily, suitable for those with limited mobility or who prefer home treatment.
Transplant surgery requires tissue matching and immunosuppressive therapy, with post-operative survival rates of over 95%. Pre-operative assessments must evaluate overall health status and tolerance to immunosuppressants, with regular anti-rejection treatment. The survival rate of living donor kidneys is usually higher than that of deceased donor kidneys, but the health risks to the donor must be assessed.
A low-protein diet can reduce the filtering burden on the kidneys, with a recommended daily protein intake of 0.6-0.8 grams per kilogram of body weight. High-sodium foods should be limited to control blood pressure, with a daily intake below 2000 milligrams. Patients with hyperphosphatemia should avoid dairy products and nuts, and use phosphate binders to reduce intestinal absorption.
A low-sodium diet can be achieved by replacing processed foods with natural ingredients, such as using herbs instead of seasonings. Fluid intake should be adjusted according to kidney function, with a recommended daily intake for end-stage kidney disease patients being 500-1000 milliliters, adjusted based on weight and urine output changes.
Moderate-intensity exercises such as walking and swimming for 150 minutes per week can improve cardiovascular health. Strenuous exercise that could further damage the kidneys should be avoided, and it is recommended to exercise under physician supervision. Stress management can be achieved through mindfulness meditation and breathing training, reducing the burden of corticosteroid secretion on the kidneys.
Mesenchymal stem cell transplantation has shown potential to repair glomeruli in animal studies, but clinical trials in humans are still ongoing. 3D printing technology attempts to reconstruct renal tubular structures and is currently in the laboratory stage, potentially offering treatment options for engineered kidney tissues in the future.
For monogenic hereditary kidney diseases, CRISPR gene editing technology can repair defective genes, but off-target effects must be addressed. Precision medicine selects medications based on the patient's genotype; for example, patients with specific genotypes that respond better to ACEIs may be prioritized for using these medications to enhance treatment efficacy.
AI algorithms can analyze changes in urinary protein and serum creatinine to predict the rate of kidney function deterioration. Wearable devices continuously monitor blood pressure and fluid balance, with data transmitted in real-time to the medical team for early intervention.
Immediate medical attention is required when there is unexplained rapid weight gain, severe lower limb edema, persistent blood pressure above 140/90 mmHg, or a sharp rise in serum creatinine. If accompanied by cardiovascular symptoms such as chest pain or shortness of breath, the possibility of uremic cardiomyopathy should be ruled out.
Abnormal symptoms such as itching in the hands and feet, nausea, or bleeding tendencies when using multiple medications necessitate reassessment of drug dosages and interactions. When creatinine clearance is below 15 mL/min or uremic symptoms (such as neuropathy or bleeding tendencies) appear, the indications for dialysis or transplantation should be evaluated.
Adjustments to medication dosages should be based on kidney function indicators such as creatinine clearance or estimated glomerular filtration rate (eGFR). When kidney function deteriorates, certain medications (such as antibiotics and antihypertensives) may accumulate in the body, increasing the risk of toxicity. It is recommended to conduct regular blood and urine tests and discuss drug metabolism pathways with the attending physician, and if necessary, switch to alternative medications with lower nephrotoxicity.
Is a low-protein diet suitable for all chronic kidney disease patients? What is the scientific basis?A low-protein diet (with a daily protein intake of about 0.6-0.8 grams per kilogram of body weight) has evidence supporting its effectiveness in delaying kidney function decline, especially in patients after stage three. This method can reduce the filtering burden on the kidneys but should be supplemented with keto acid supplements to avoid malnutrition. However, patients with diabetes or insufficient muscle mass should adjust based on a dietitian's assessment and should not implement it blindly.
When should a patient be referred to a nephrologist for specialized treatment?Patients should be referred to a nephrologist when they exhibit persistent proteinuria (urinary protein excretion >3 grams/day), a sharp rise in serum creatinine levels, or complications such as hypertension and anemia. If the estimated glomerular filtration rate (eGFR) remains below 30 mL/min/1.73m² for more than three months, it indicates progression to end-stage kidney disease, necessitating evaluation for lifelong treatment options such as dialysis or transplantation.
What personalized factors should be considered when choosing between hemodialysis and peritoneal dialysis?Hemodialysis requires regular hospital visits and is suitable for patients who can adhere to treatment schedules and have good vascular conditions; peritoneal dialysis requires daily self-administration at home and is suitable for those with limited mobility or who prefer more flexible time management. Considerations should include infection risks (such as a higher risk of peritonitis for peritoneal dialysis), residual kidney function status, and the patient's lifestyle and care support system.
Can traditional Chinese medicine be used alongside Western medicine? Are there any contraindications to be particularly aware of?Traditional Chinese medicine may contain nephrotoxic components such as aristolochic acid, and concurrent use with Western medications may exacerbate kidney damage, so strict avoidance is necessary. Non-pharmacological therapies such as acupuncture or cupping can be used as adjunct therapies, but it is essential to choose practitioners with experience in kidney disease. Patients should inform their physicians of all traditional herbal or supplementary therapies used to minimize the risk of drug interactions.
