End-stage renal failure (ESRD) is a critical condition in which the kidneys lose their ability to perform their basic functions of filtering blood and removing waste from the body. This is the final stage of chronic renal failure (CRF), in which the glomerular filtration rate falls below 15 ml/min, leading to the accumulation of toxic substances and disturbances in water and electrolyte balance. ESRD can develop as a result of various pathologies, such as diabetic nephropathy, hypertension, glomerulonephritis, and also as a result of acute kidney injury. Without adequate treatment, ESRD becomes a life-threatening condition requiring urgent medical care, including dialysis or kidney transplantation.
History of the disease and interesting historical facts
The history of kidney disease goes back many centuries, beginning in ancient times when problems with kidney function were known but poorly understood. The first mentions of kidney disorders can be found in the works of ancient Greek and Roman physicians. For example, Hippocrates and Galenius described various kidney diseases and their symptoms. Remarkably, understanding of the relationship between kidney disease and other systemic conditions began to emerge only in the 18th and 19th centuries.
In the 1940s, the first dialysis technology brought a breakthrough in the treatment of end-stage renal failure. However, the real revolution occurred in the 1960s with the introduction of hemodialysis, which significantly increased the survival rate of patients with ESRD. In the following decades, kidney transplantation became the mainstay of treatment for this pathology, changing approaches to therapy and patient care.
Epidemiology
End-stage renal failure is an important public health problem. According to the World Health Organization (WHO), the incidence of CRF is increasing worldwide: in low- and middle-income countries, it is growing to 5-10% per 1000 population. In developed countries, this figure varies from 1 to 2% depending on age and comorbidities. More than 2 million patients are treated with dialysis, and this number continues to grow every year.
According to the Centers for Disease Control and Prevention (CDC), more than 40% patients with ESRD experience worsening cardiovascular health. Mortality rates among patients with ESRD remain high, especially in those with underlying medical conditions such as diabetes and hypertension.
Genetic predisposition to this disease
Some studies suggest that genetic predisposition may play a significant role in the development of end-stage renal disease. Certain mutations in genes such as PKD1 and PKD2 are associated with polycystic kidney disease, which is a major predictor of CRF. Mutations in the JAGN1 and TRPC6 genes, which may be associated with hereditary nephropathies, are also being studied.
It is important to consider that not all genetic changes lead to the development of the disease directly, but they can aggravate the course of the existing pathology. Genetic tests can provide useful information about the risks of developing ESRD, especially in people with a family history of kidney disease.
Risk factors for the development of this disease
There are many risk factors that contribute to the development of TSRD. The main ones include:
- Diabetes mellitus: one of the leading diseases that causes kidney damage.
- Arterial hypertension: High blood pressure also significantly increases the risk.
- Genetic predisposition: having relatives with CRF increases the likelihood of developing it.
- Age: As you age, your risk of kidney failure increases.
- Chronic kidney disease: The presence of other forms of CKD directly increases the risk of reaching the end stage.
Environment and lifestyle also play an important role; bad habits such as smoking and alcohol abuse, as well as poor diet and lack of physical activity can contribute to the development of ESRD.
Diagnosis of this disease
Diagnosis of TSPI involves a comprehensive approach consisting of various examination methods. The main symptoms of the disease include fatigue, swelling, loss of appetite, nausea, and changes in urination, such as an increase or decrease in urine volume.
Laboratory tests include blood creatinine and urea levels, as well as electrolytes. Creatinine levels are clearly elevated, indicating worsening kidney function. Urine testing for albuminuria is also recommended.
Radiological examinations such as renal ultrasound may reveal changes in the size and structure of the kidneys. In more complex cases, a kidney biopsy may be needed to confirm the diagnosis.
Differential diagnosis includes other causes of renal failure, such as acute glomerulonephritis or nephrotic syndrome, which require different treatment approaches.
Treatment
Treatment of ESRD depends on the stage of the disease and the underlying cause of renal failure. The main therapeutic strategies are:
- Conservative methods: management of comorbidities such as diabetes and hypertension using antihypertensive and antiglycemic agents.
- Hemodialysis: A process in which the blood is cleansed of toxins and wastes outside the body.
- Peritoneal dialysis: A technique that uses the peritoneum as a filter to remove waste from the blood.
- Kidney transplantation: the most effective treatment for ESRD, ensuring restoration of kidney function.
Drug treatment may include medications to control blood pressure, statins to lower cholesterol, and phosphate binders to manage phosphorus levels.
List of medications used to treat this disease
- Erythropoietin - to correct anemia.
- Calcitriol - for managing calcium balances.
- Lanrep - for the treatment of hyperparathyroidism.
- ACE inhibitors - to control blood pressure.
- Diaphoretic agents - to control the level of toxins in organs.
Disease monitoring
Monitoring the condition of a patient with ESRD requires regular monitoring of the number and status of clinical parameters. The main stages of monitoring include:
- Regular blood tests for creatinine and electrolyte levels.
- Visit your doctor at least once a month to assess your health.
- Discussion of treatment and the need for dialysis or transplantation depending on the dynamics of the condition.
The prognosis for ESRD depends largely on prompt initiation of therapy. With complications such as recovery of kidney function after dialysis or problems with transplantation, the chance of survival is still significantly lower than in people without kidney problems.
Age-related features of the disease
The manifestation of ESRD varies depending on the age group. Children and adolescents often have hereditary mild forms of deficiency, while in the elderly the disease is most often associated with comorbidity and age-related changes. A large number of cases are diagnosed in the younger generation with diabetes or hypertension, while elderly patients with ESRD experience deterioration of body function due to other chronic diseases.
Questions and Answers

- How is TSPD diagnosed? Diagnosis includes laboratory tests for creatinine levels, urine analysis, and radiological studies.
- How is TSPD treated? Treatment may include dialysis, transplantation, management of co-morbidities, and drug therapy.
- Who is at risk for developing TSPD? Those at risk include patients with diabetes, hypertension, and family members with a history of kidney disease.
Advice from Dr. Oleg Korzhikov
According to Dr. Oleg Korzhikov, it is important to monitor the condition of the kidneys from an early age and undergo regular examinations, especially for people with risk factors. Advice from the specialist includes:
- Maintaining a healthy lifestyle with regular exercise and a balanced diet.
- Regular monitoring of blood pressure and blood sugar levels in people with a predisposition to kidney disease.
- Conducting an ultrasound examination of the kidneys at least once every five years to assess the condition of the organ.
The doctor emphasizes that early detection and appropriate treatment significantly improve the prognosis and quality of life of patients.
