Influence of phosphate restriction, keto-acids and vitamin D on the progression of chronic renal failure.

Progression of renal failure was investigated in a prospective follow-up study of 60 patients with mild and 100 patients with advanced renal failure. Phosphate restriction in mild and protein restriction in advanced renal failure can delay the progression rate of patients with chronic renal insufficiency. Simultaneous administration of Vitamin D does not effect the progression. Administration of keto-acids to the low protein diet has a strong delaying effect on the progression rate.

[Controlling renal osteopathy with keto acids].

Starting from the results of former investigations the influence of the long-term treatment with the KA of the essential amino acids on the renal osteopathy is investigated. For this purpose we compared 27 patients with renal insufficiency (serum creatinine 981 +/- 354 mumol/l), who besides vitamin D had been treated with KA for at least 12 months, to a group of 50 patients (serum creatinine 778 +/- 273 mumol/l), who had received vitamin D over 19 +/- 9 months, and to a control group of 27 patients (serum creatinine 928 +/- mumol/l) without an adequate conservative therapy. While the control group showed the typical constellation in advanced renal insufficiency with hypocalcaemia, hyperphosphataemia, clearly increased PTH levels, clearly increased CT values and normal 25-OH-D concentrations, during the diettherapy and the vitamin D substitution a significant increase of the serum levels of calcium, 25-OH-D and CT as well as a significant decrease of the PTH and the anorganic phosphate in the serum developed. Under the combination therapy with KA and vitamin D despite the reduction of the phosphate binders another significant decrease of the PTH and the anorganic phosphate was observed. The mineral content of the bones was within the normal in the two therapy groups. The percentage of the normal histological findings of the bones was with 40.7% highest despite the advanced renal insufficiency in the simultaneous substitution with KA. While in the vitamin D group during the control biopsy after 12 months in 20.5% of the cases an improvement of the histological findings developed, this effect occurred under additional KA-therapy in 51.9% of the cases. The results allow the conclusion that by means of the long-term treatment with KA a favourable influence on the renal osteopathy develops.

Influence of keto acids on serum parathyroid hormone levels in patients with chronic renal failure.

The metabolic effects of short-term and long-term treatment by keto acids were examined in 46 patients with chronic renal failure. Long-term as well as short-term administration to chronic uremics resulted in a significant reduction of serum PTH and inorganic phosphate levels while serum concentrations of serum calcium, 25-OH-D and calcitonin were not influenced. The results presented in this paper allow the conclusion that keto acid treatment of patients with chronic renal failure may be helpful in the control of abnormal calcium-phosphate metabolism and secondary hyperparathyroidism.

[Treatment trials with hemofiltration/hemodialysis in pernicious catatonia].

Two juvenile patients affected for the first time with pernicious catatonia were treated repeatedly with combined hemofiltration and hemodialysis. During the first two or three sessions, the distinct psychopathological improvement only persisted during the session itself and in a lesser degree during the following hours. It was only after further treatments that the therapy effect lasted longer and passed over into a continuous remission tendency. The findings might support a toxin hypothesis (in a broad sense) with respect to the genesis of catatonia and encourage a continuation of the studies.

[Homologous umbilical vein and vena saphena transplants as possible means of vascular access in chronic hemodialysis].

For a patient in the chronic programme of haemodialysis an uncomplicated accession to the vessels is the prerequisite for an optimum medical and social rehabilitation. Each form of a subcutaneous arteriovenous fistula is to be preferred to an epicutaneous shunt prosthesis. The percutaneous puncture of large vessels is necessary for the rapid connection to the dialyses in acute situations. In long-term treatments often all autologous accessions to the vessels are used up. Homologous substitution material for vessels is increasingly used also in patients ongoing dialysis. Apart from the methods for gaining homologous material is reported on first experiences in the application of homologous grafts of the umbilical vein and of a homologous vena saphena graft in patients undergoing dialysis.

[The status of extracorporeal detoxication procedures as a therapy method in schizophrenia].

The literature on the problem of extracorporeal detoxication in chronic schizophrenia was critically studied. For the statistically considered 132 cases of chronic schizophrenia without uraemia treated with haemodialysis, haemoperfusion and haemofiltration which are published in the literature (including 12 own cases) it was found that 38 per cent are considered as improved. The insufficient comparability of the examination methods and the want of clearness with respect to the specific therapy influence (placebo effect, etc.) leave the question open whether these are in fact efficient methods of treatment for some cases of chronic schizophrenia. A final decision on this requires continued, methodically more strictly controlled, and above all standardised examinations. The results obtained until now make efforts in this direction appear reasonable.

[Possibilities of emergency coronary surgery in acute myocardial ischemia (clinico-experimental study)].

The work is based on the analysis of data on 20 patients with acute myocardial infarction who underwent emergency operations for aorticocoronary shunting and on the findings of 50 dog experiments. Comparison of experimental and clinical data showed that the extrapolation of experimental parameters to a sick person should be undertaken with caution and with a greater probability for groups of patients suffering from myocarial infarction for the first time and with no chronic ischemic heart disease. A time period of six hours from the moment symptoms of myocardial infarction develop is the optimum term for emergency aorticocoronary shunting. A successful operation, however, is also possible at later periods, 15 to 18 hours form the time myocardial infarction develops.

[Haemodialysis in patients with pre- andpostoperative acute renal failure (author's transl)].

Treatment and management of patients with renal insufficiency before and after surgery is often complicated. Early interdisciplinary cooperation between intensive care specialist, surgeon, gynaecologist, urologist and nephrologist is necessary. The mortality rate of patients with acute renal failure is still high (50 to 60%). The increase in patients with chronic renal failure who are in need of haemodialysis involves more surgical procedures in this group even in future.

[Studies of disinfection of hemodialysis instruments].

Fever reactions in dialysis patients may partly be traced back to the transmission of pyrogens from the rinsing solution compartment into the sanguiferous system. The pyrogen concentration increases with the germ contents of the rinsing solution, which, therefore, should be kept as low as possible by suitable desinfection measures. For the artificial kidney Gambro AK 3 a hot water desinfection of 90 minutes at 90 degrees C or a formalin desinfection of 30 minutes, respectively, for the artificial kidney Leuven IIIC the formalin or peracetic acid desinfection of 30 minutes each proved to be sufficient.
