Uremia occurs when there is a build-up of waste products in the blood due to kidney dysfunction or failure. Urea, creatinine, and other waste products usually excreted by the kidneys can build up in the blood, leading to various symptoms and complications.
Uremia can occur due to chronic kidney disease, acute kidney injury, or other conditions that affect the function of the kidneys, such as diabetes, high blood pressure, and certain autoimmune diseases.
It is believed that certain substances, such as macroglobulin, parathyroid hormone, advanced glycosylation end products, and beta2 microglobulin, may be uremic toxins. However, it is unclear whether any specific toxin is solely responsible for all clinical symptoms associated with uremia.
Epidemiology
Determining the actual prevalence of uremia in the United States is challenging because individuals with end-stage renal disease (ESRD) often start dialysis before experiencing uremic manifestations. Uremic symptoms typically appear when creatinine clearance drops between 10 to 15mL/min in individuals with diabetes.
Each year, around 354 out of one million people are diagnosed with ESRD. However, this number is increasing due to improved survival rates among individuals with cardiovascular disease or diabetes and greater pass to renal therapy. ESRD is common in individuals aged 75 or older, while the number of people under 60 with ESRD decreases, except for Native American or African American patients with diabetic ESRD.
ESRD is 1.2 times more prevalent in men than women, while women tend to postpone dialysis initiation by 1.7 times. Additionally, women are more susceptible to uremia at lower creatinine levels due to their baseline serum creatinine levels and lower muscle mass.
Anatomy
Pathophysiology
When the kidneys fail to function correctly, it can result in various abnormalities, including disturbances in acid-base homeostasis, regulation of fluid and electrolytes, hormone production and secretion, and waste excretion. These abnormalities can lead to metabolic disturbances, anemia, hypertension, hypothyroidism, acidemia, malnutrition, and hyperkalemia.
In addition, chronic kidney disease can contribute to the development of anemia, which vitamin or iron deficiencies, hypothyroidism, hyperparathyroidism, or a decreased lifespan of red blood cells can cause. One of the consequences of kidney dysfunction is the buildup of uremic toxins in the blood, which can contribute to coagulopathy or increased hemorrhage and susceptibility to bleeding.
Patients with end-stage renal disease are particularly prone to bleeding diathesis, possibly due to decreased platelet adhesion to the vascular endothelial wall, a slightly reduced number of platelets, and increased platelet turnover. Moreover, reduced renal function can lead to a decrease in insulin clearance, which requires adjusting the doses of antihyperglycemic medications to avoid hypoglycemia. Uremia can also affect reproductive hormone regulation, leading to men’s impotence, infertility, amenorrhea, and anovulation in women.
Additionally, the accumulation of uremic toxins can contribute to uremic pericardial effusions and pericarditis, resulting in abnormalities in cardiac function. Furthermore, metastatic calcification due to reducing renal function can worsen underlying valvular dysfunction or suppress myocardial contractility, further impairing heart function. Kidney dysfunction can result in various complications, affecting various organ systems and decreasing quality of life.
Etiology
Kidney disease can arise from various conditions, including primary renal disorders such as focal segmental glomerulosclerosis, IgA nephropathy, polycystic kidney disease, and membranoproliferative glomerulonephritis,as well as systemic disorders like amyloidosis, lupus, multiple myeloma, Thrombotic thrombocytopenic purpura, Goodpasture disease, and hemolytic uremic syndrome that can cause renal damage.
In the United States, diabetes is the leading cause of ESRD, followed by glomerulonephritis, hypertension, cystitis, interstitial disease, and neoplasms. Additionally, acute kidney injury can lead to uremia if it causes a sudden increase in the urea or creatinine levels.
Genetics
Prognostic Factors
Patients with uremia have a poor prognosis in the absence of medical intervention. However, it can be improved with dialysis or transplantation. Nonetheless, careful monitoring is imperative due to the tendency of patients to develop complications.
Although mortality rates have declined in the last 30 years, individuals suffering from renal failure still face a greater mortality risk than the general population. The leading cause of death in these patients is progressive cardiovascular disease.
