Optimisation of stroke prevention for dialysis patients

The anticoagulants currently used to prevent strokes in dialysis patients with atrial fibrillation do not provide adequate protection for this group. This is the finding of a study led by Oliver Königsbrügge and Cihan Ay ...

Dialysis patients benefit from a third COVID vaccination dose

Just like diseases, vaccines cause the body to form an immunological memory. This memory can prevent a second infection or illness caused by the same pathogen. "Put simply, specific immunity is based on antibodies that prevent ...

Dialysis

In medicine, dialysis (from Greek "dialusis", meaning dissolution, "dia", meaning through, and "lusis", meaning loosening) is primarily used to provide an artificial replacement for lost kidney function (renal replacement therapy) due to renal failure. Dialysis may be used for very sick patients who have suddenly but temporarily, lost their kidney function (acute renal failure) or for quite stable patients who have permanently lost their kidney function (stage 5 chronic kidney disease). When healthy, the kidneys maintain the body's internal equilibrium of water and minerals (sodium, potassium, chloride, calcium, phosphorus, magnesium, sulfate) and the kidneys remove from the blood the daily metabolic load of fixed hydrogen ions. The kidneys also function as a part of the endocrine system producing erythropoietin and 1,25-dihydroxycholecalciferol (calcitriol). Dialysis is an imperfect treatment to replace kidney function because it does not correct the endocrine functions of the kidney. Dialysis treatments replace some of these functions through diffusion (waste removal) and ultrafiltration (fluid removal).
