[Therapy and prophylaxis of renal failure]

The number of patients with end-stage renal disease is constantly growing. If patients at risk are identified early enough, currently available therapeutic options allow a potent primary and secondary prevention of progressive renal failure. If the underlying disease can not be eliminated, the mainstay of the therapy are supportive measures such as antihypertensive and, in case of an underlying diabetes mellitus, antidiabetic therapy, dietary restrictions as well as avoidance of additional nephrotoxic agents. Furthermore, even a mild renal insufficiency has been identified as a potent cardiovascular risk factor. The second major goal of supportive therapy therefore is a reduction of the markedly increased cardiovascular morbidity of these patients. This can be achieved through treatment of various consequences of renal failure, such as hyperparathyroidism, renal anemia etc. Supportive therapy thus represents a highly complex and interdisciplinary treatment, which should prompt an early inclusion of a nephrologist into the therapeutic strategy.
