Foley et al.; Diabetologia 1997

Diabetic patients appear to be more sensitive than nondiabetics to inadequate dialysis prescriptions. It has been estimated, for example, that there is a seven percent increase in mortality in diabetics for every 0.1 unit decline in Kt/V.

Collins, AJ. How can the mortality rate of chronic dialysis patients be

reduced? Semin Dial 1993

The potential importance of malnutrition is suggested by the observation that the increase in mortality (when compared to nondiabetics) largely disappears if reductions in the plasma albumin and creatinine concentrations (that primarily reflect inadequate intake) are taken into account

Percentage technique survival for diabeticand non-diabetic patients on CAPD

Serkes KD et al.; Perit Dial Int 1990

Dialysis in patients with diabetes

• decreased survival rate due to cardiovascular disease

• cave: inadquate dialysis prescriptions

• cave nutritional status

• decreased (PD-) technique survival rate

• (progression of microvascular diabetic complications)

Would optimal treatment of diabetes improve these outcomes?

Insulin therapy

• Renal clearance• Insulin degradation• Hepatic insulin metabolism

• Insulin sensitivity• Insulin secretion

Insulin therapy

• subcutaneous insulin in PD patients

• twice-daily intermediate/regular insulin

• basal-bolus regime

• CSII (insulin pump therapy)

Insulin therapy

Subcutaneous insulin in PD patients (basal-bolus regime)

• conventional long-acting insulin (NPH, lente)

once- or twice daily with conventional regular insulin

• long-acting insulin-analogue (glargine, detemir)

with short-acting insulin analogues (lispro, aspart)

• long-acting insulin-analogue (glargine, detemir)

with conventional regular insulin

Insulin therapy

Insulin therapy

Intraperitoneal insulin in PD patients

• use regular insulin four times daily in CAPD

• use regular insulin (in all dialysis containers) in CCPD

and either i.p. regular insulin for the daytime exchange

or supplemental s.c. infusion for meals

• subcutaneous insulin in HD patients

• twice-daily intermediate/regular insulin

HOE DIT AF TE STEMMEN MET DE DIALYSE?

Current / future aspects:

• GLP-1 (glucagon like peptide) and -/ GIP

(gastric inhibitory polypeptide)

• GLP-1/GIP derivatives (exendin-4, liraglutide)

• DDP-IV inhibitors (sitagliptine/vildagliptine)
