[Clinical value of interleukin 1- and interleukin 2-determinations in patients after kidney transplantation].

In a retrospective study of allograft rejections in renal transplant recipients we examined the value of cytokine production monitoring. Interleukin 1 (IL 1) and interleukin 2 (IL 2) activities were determined in supernatants of mitogen-stimulated peripheral blood lymphocytes in 8 renal transplant recipients serially for a period up to 60 days after transplantation. LPS-induced IL 1 as well as PHA-induced IL 2 production in patients after renal transplantation were significantly decreased in comparison to healthy controls.

[Preparation and implementation of kidney transplantation in patients with terminal renal failure and type I diabetes].

The newest results of transplantation in diabetic nephropathy (diabetics type I) of the world were described according to the data of the EDTA and after the symposium in The Hague. Own experience in the field of transplantation carried out in diabetics needing insulin with terminal renal failure were critically evaluated. The investigations in several centres of the GDR concerning the decompensation of diabetic nephropathy show that it is necessary to perform a three- to six-month creatinine control in long-term diabetics from the 15th year of the disease and from a serum value of 200 mumol/l to carry out in good time a common diabetological and nephrological control with test concerning the fitness for a kidney transplantation.

[Cell electrophoresis studies of peripheral blood lymphocytes in patients following kidney transplantation].

In 111 patients (control group, dialysis patients, kidney recipients) the behaviour of T lymphocytes was observed using an automatic measuring apparatus ( Parmoquant cytopherometer ) and the spontaneous rosette test. The Parmoquant method gives no information on the process of rejection, but it helps to identify risk situations due to bacteria of viruses. In cases of rejection after the second post-operative week, the results of the two methods are reversed.
