![]() Improved survival in patients with diabetes or cardiovascular disease, in addition to increased access to renal therapy, has resulted in the highest increase in the incidence of ESRD in patients aged 75 years or above. ![]() This number continues to rise as the life expectancy of those with ESRD is increasing. According to the United States Renal Data System (USRDS) 2009 data, the incidence and prevalence of advanced chronic kidney disease in the United States were reported to be 3 per million people per year. In 2009, 116,395 patients started renal replacement therapy, accounting for an unadjusted incidence of 371 per million. Uremic symptoms typically arise once creatinine clearance is less than 10mL/min or 15mL/min in the case of diabetic patients. It is difficult to determine the exact prevalence of uremia in the United States because patients with ESRD typically begin dialysis before developing uremic symptoms. Uremia may also result from acute kidney injury if the injury involves a sudden increase in urea or creatinine. Additional causes, listed in order of decreasing incidence, include hypertension, glomerulonephritis, interstitial disease, cystitis, and neoplasms. Diabetes is the leading cause of kidney failure worldwide however, glomerulonephritis is the more predominant underlying cause in developing countries. The leading cause of ESRD in the United States is diabetes accounting for 40% of new dialysis patients. Systematic disorders can include diabetes mellitus, systemic lupus erythematosus, multiple myeloma, amyloidosis, Goodpasture disease, thrombotic thrombocytopenic purpura, or hemolytic uremic syndrome. Uremia can result from some conditions ranging from primary renal disorders, for example, IgA nephropathy, focal segmental glomerulosclerosis, membranoproliferative glomerulonephritis, polycystic kidney disease) to systemic disorders that can lead to renal damage. Putative uremic toxins include parathyroid hormone, macroglobulin, advanced glycosylation end products, and beta2 microglobulin, though no specific uremic toxin has been identified as responsible for all clinical manifestations of uremia. ![]() Early recognition of skin changes and prompt management initiation can dramatically alter the course of illness and decrease morbidity. These manifestations affect a patient's quality of life considerably. There could also be other signs and symptoms, such as increased thirst and visual changes. Uremia can lead to various cutaneous abnormalities, such as changes in skin color, xerosis, pruritus, hair, nail, and oral changes, bullous dermatosis, and metastatic calcinosis. Patients with uremia generally present with nausea, vomiting, fatigue, anorexia, muscle cramps, pruritus, and altered mentation. For instance, neurological complications also occur with uremia, and polyneuropathy is a common manifestation of uremia, especially when treatment with renal replacement therapy is started too late. Urea itself is both directly and indirectly toxic to a range of tissues. Still, it may also occur due to acute kidney injury if loss of kidney function happens rapidly. The literal meaning of uremia is "urine in the blood," which develops most commonly in chronic and end-stage renal disease (ESRD). Uremia, a clinical condition associated with worsening renal function, is characterized by fluid, electrolyte, hormone imbalances, and metabolic abnormalities.
