Hyperglycinuria with nephrolithiasis.

The case of a seven and a half-year-old girl with hyperglycinuria, oxalate nephrolithiasis, and a normal plasma amino acid pattern is presented. Hyperglycinuria amounted to 400 mg of glycine in 24 h urine and the stone was composed of calcium oxalate dihydrate. The metabolic relationship between glycine and oxalate is discussed. It is possible that the association of nephrolithiasis and hyperglycinuria was coincidental, although the case of familial hyperglycinuria with nephrolithiasis reported by De Vries and collaborators and our case suggest the possibility of a relationship between the aforesaid compounds in vivo.

[Long-term follow-up of related kidney donors after nephrectomy].

From 1973 to July 1990, 183 kidney transplantations were performed at the Transplantation Unit of the Department of Urology--Faculty of Medicine--University of Zagreb. Out of these, 57 were from the living related donors. The research included 50 (88%) living related donors (28 mothers, 12 fathers, 5 brothers and 5 sisters) followed up from 1 to 15 years after donor nephrectomy. The donors' health conditions were evaluated by clinical-laboratory examinations (biochemical tests, renal function tests, urinoculture, ultrasound, isotopic renal studies, arterial blood pressure). In 48 (96%) neither morphological nor functional changes of the urinary system were found. A certain number of donors requested a transfer to less physically strenuous jobs. Except for the grafts functioning well in the recipients, the results also showed that the quality of donors' lives remained unchanged.

[The nail-patella syndrome].

The nail-patella syndrome (synonym of onychoosteodysplasia) is considered to be an autosomal dominant hereditary disease affecting numerous tissues of ectodermal and mesodermal origin. The changes are mostly found on nails, patellae, eyes and joints. The symptoms of nephropathy are present in 30% to 40% of patients, and renal insufficiency with typical signs of the syndrome in 25% of patients. This report describes a female patient with renal insufficiency on chronic hemodialysis treatment, in whom diagnosis of the nail-patella syndrome has been made at 36 years of age. The incidence of the syndrome has been noted in 11 members of the patient's family, but without clinical signs of nephropathy.

[Immunologic and clinical definition of the rejection reaction in kidney transplantation].

In the evaluation of the immunological state of a kidney transplant there is no reliable diagnostic test. Therefore, several various tests should always be applied. The aim of this study was to define the type of immunological reaction (cellular or humoral) that causes the rejection of transplanted kidney. A group of 45 patients with a kidney transplant were tested 175 times, in various phases of the kidney transplant, starting on the day of transplantation up to several months posttransplant. Specific antibodies (SA) and specific cytotoxic lymphocytes (SCL) directed against donor cells in lymphocyte-mediated cytolysis tests in the presence of antibodies (ADLMC) or without them (LMC) were determined. LMC was significantly correlated with acute rejection (85%). In the phase of clinical quiscence of the kidney transplant LMC was positive in 4% of the cases. During the period of chronic rejection it was positive in 75% of the cases. ADLMC test is significantly correlated with chronic rejection (88%). In the period of acute rejection it was positive in 27% while in clinical quiscence in 11% of the cases. Twenty-two patients with non-immunological disorders of the kidney transplant were tested 62 times. LMC test was always negative, while ADLMC test was positive in 6.4% of the cases. These tests prove to be good parameters for defining immunological reaction. Thus, they can be of great importance in determining adequate immunosuppressive therapy. Negative results of tests in non-immunological disorders of graft function are highly significant.
