[Clinical issues with uremia].
Uremia describes the consequences of intoxication in chronic renal failure with substances that are renally cleared in healthy individuals. Acute uremia is a syndrome of gastrointestinal symptoms, pericarditis, pleuritis, and central nervous system alterations ending with coma. These symptoms can be resolved by renal replacement therapy. In addition, chronic uremia can result in damage of multiple organ systems, which continues to advance despite dialysis therapy. This is caused by retention of toxins that cannot be adequately removed due to insufficient treatment time or a molecular weight range hampering elimination. Uremic toxins can be generated by the energy or nucleic acid metabolism, they can be proteins or large molecules that are altered chemically by the uremic milieu. Chronic uremia can influence the majority of long-term complications of chronic renal failure: systemic microinflammation, cardiovascular disease, immunodeficiency, malnutrition, anemia, bone metabolism, and polyneuropathy. There are few therapeutic options other than kidney transplantation.
