[Comparison of automated micro-disc electrophoresis for the analysis of urine proteins with a conventional system].

Recently a new system for analyzing urinary proteins due to their molecular weight distribution has been introduced. The whole system is automatically driven and uses a silver staining. Due to the small amount of protein necessary for analysis native urine samples can be used. The data presented here show that the automatic micro-disc-electrophoresis (Phast-system) is very useful for any routine testing due to the quick (2 hours) and easily obtainable results with a very high reproducibility. The clinical relevance of urinary protein analysis seems to be much higher using this system.

[Therapy of urinary tract infection from the internal medicine viewpoint].

Effective treatment of urinary tract infection is dependent on a precise case history and a thorough physical examination. Before using antibacterial compounds it is mandatory that the physiological defense mechanisms be actively supported by nonspecific actions. Depending on the environment where patients are being cared for (general practitioner--hospital), the antibacterial therapy should take into account bacteriological information on the sensitivity of the bacteria to antibacterial agents.

[The perfusate culture--bacteriologic monitoring of kidney grafts].

Since the kidney recipient's immune system is entirely suppressed, any bacterial contamination from a graft might be hazardous. Major statistics [1,3,4,5] reveal a mortality as high as 10% due to infectious and gastrointestinal complications. From July 1979 to December 1983 114 kidney grafts have been done in our center. After transplantation none of the patients died as a result of complications due to infection. Microbiologic examination of the perfusate is obligatory to detect contamination. It was used in 145 donor nephrectomies; 28% of the perfusate culture samples were positive: In 4 of 5 cases (81%) the bacteria isolated were of the non-pathogenic type seen in the normal flora of the skin (Staphylococcus epidermidis). Introduction of cover drapes lowered the positive culture rate to 8%. Isolation of S. epidermidis after desinfection of the skin (6x) with 70% spore-free alcohol is proof of the extraordinary sensitivity of the method used. The outstanding clinical importance of this method is the rapid information obtained on any contamination and the early suggestion concerning the first choice of antibiotic. Though E.coli and Pseudomonas aeruginosa were found in the culture, no clinical infection was seen under adequate antimicrobial therapy. Among 114 kidney transplantations in our center no patient died of bacterial infection. Our experience points out that the effect of general antibiotic prophylaxis is negligible. Instead, the effect of early application of antibiotics in accordance with the results of the perfusate culture is superior.

How to detect bacterial contamination prior to transplantation.

The mortality of kidney transplantation generally amounts to 10% due to infections and GIT complications. Once grafting a Staphylococcus aureus and Streptococcus contaminated kidney the recipient had to undergo emergency surgery four times. Hence it has become our routine to sample the perfusate on blood culture media. Among 145 donor nephrectomies the microbiologic examination of the kidney perfusate in which the graft is stored and transported turned out to be positive in 28%. Four out of five germs isolated after incubation on blood culture media were of the non-pathogenic type seen in the normal flora of the skin. Making use of the CIT (24-30 hours) we cultured the perfusate on blood media. Since the temporary results of the microbiological examination are obtained within 12 hours we can initiate the first choice antibiotic therapy already at the time of transplantation. Though there was proof of highly pathogenic bacteria clinical infection occurred in none of our patients among a total of 114 grafts. The outstanding clinical importance of this diagnostic tool arises from the time sparing information of any contamination and the early hint at the first choice of antibiotics. The distinct application of antibiotics according to the result of the perfusate culture on blood culture media is superior to a general antibiotic cover.

Therapeutic regimen of septic vascular complications in kidney grafting.

In spite of highly sophisticated tissue matching reducing immunogenicity of a graft a high degree of immunosuppression is mandatory to achieve good graft survival. Septic complications such as a rupture of an anastomosis threaten the recipients life. Thorough donor selection, strict asepsis, as well as repeated bacteriologic examination gives the chance to decrease morbidity and mortality of kidney grafting. In the retrospective analysis of 135 kidney transplantations septic vascular complications occurred in 3.7%. The surgical procedure of choice after graft removal is the ligation of the external iliac artery. Only in one out of four cases ischemia of the lower extremity had to be treated by an extra-anatomic femoro-femoral bypass.

[Glomerular proteinuria in pregnancy hypertension].

In view of the lack of reliable diagnostic parameters for predicting pregnancy-induced hypertension (PIH) the aim of this study was to test the prognostic value of electrophoretic urinary protein patterns. Based on experience with this method in nephrology, molecular weight related polyacrylamide-gel-electrophoresis (PAGE) of urinary proteins was used to distinguish between the different kinds of renal lesions (glomerular, tubular, combination, extrarenal). The analysis was carried out in two independent groups: urines of 126 non-selected pregnant women (1st group) were analysed at regular intervals. By chance, none of them had a history of previous PIH or hypertension, nor any signs of impaired renal function before or during the present pregnancy. In a 2nd group 124 women after severe PIH (pd greater than or equal to 110 mm Hg) were examined in part using PAGE, postpartum renal biopsy and long-term clinical follow up (greater than or equal to 1 year after PIH). In 29/124 cases data for all mentioned parameters was collected. 24 women of the prepartum group developed an electrophoretic pattern characteristic of glomerular proteinuria, which was persistent once found. PIH appeared greater than or equal to 8 weeks after the appearance of this pathological pattern in 15/24 women of this subgroup; 5 of 9 remaining women developed PIH in a subsequent pregnancy. None of the 102 women with other protein patterns developed PIH. In the 2nd group a close relationship was found between the glomerular protein patterns 0.5 to 3 years after PIH, clinical long-term follow up and renal biopsies about 1 year after PIH.(ABSTRACT TRUNCATED AT 250 WORDS)
