For decases certain diseases, such as glomerulonephritis, polyarteritis nodosa, scleroderma and serum sickness, have been linked with autoimmune pathogenesis. During recent years a host of additional diseases traditionally thought to have some genetic predisposition but with obscure etiology have been suspected of being autoimmune in nature. Rheumatoid arthritis, diabetes, myasthenia gravis and thyroiditis are diseases of widely divergent organ systems, yet may well have common pathways of pathology via immune complexing mechanisms. Herein we present evidence supporting the concept that renal artery stenosis (occurring primarily in association with the middle aortic syndrome or after renal transplantation) is of immune etiology. Although the specific antigenic agent is still to be defined there is growing acceptance of the theory that medium and large vessels are subject to autoimmune vasculitis in many aspects similar to the autoimmune affections of small vessels. Several cases are presented. Some of these suggest an immune reaction by the natural history but without evidence of immunochemical reactants in the involved vessels, presumably because active disease was arrested at the time to study. In other cases immunofluorescent preparations demonstrate reactants in the walls of the vessels to document the hypothesis more convincingly.

The investigation covers the necropsic material of the Pathological Anatomy Chair, Medical Academy-Sofia, with a total of 3519 necropsies for a period of 5 years (1968--1970). In that material, 285 cases with uremia were established, due to chronic renal diseases, which might be referred to 13 nozological entities. The highest number of cases are with chronic pyelonephritis (64,96 per cent). The chronic glomerulonephritis, though it ranks second, is considerably rarely met (9,47 per cent). Endemic nephropathy, according to the incidence, follows--4,21 per cent, nephropathy in diabetes mellitus--3,86 per cent, subacute glomerulonephritis--3,16 per cent, amyloidosis--2,81 per cent, hypertonic disease--2,81 per cent, malignant tumors of the kidneys--2,81 per cent cystic kidneys--2,10 per cent, lupus erythematosus--1,05 per cent, sclerodermia--0,70 per cent, myeloma disease--0,70 per cent and polyarteriitis nodosa--0,35 per cent. As to the chronic renal disease, most frequently met in the material discussed, the chronic pyelonephritis, the authors discuss the factors that played certain role in its development as well.

Indications, selection of donor and recipient, medical and surgical management and complications, problems of organ procurement. Renal transplantation has become routine therapy. Organs are predominantly obtained from cadavers, transplantations from living donors are rarely indicated. Advances in preservation methods have improved organ quality and prolonged storage time. Selection of the most suitable recipient is based on histocompatibility matching. Blood transfusions before transplantation seem to improve the results. Recognition of a rejection crisis is primarily based on clinical symptoms. Persistent rejection calls for prompt explantation and the patient has to return to dialysis. Infections, serum-hepatitis and gastro-intestinal bleeding are the most common complications. Late complicatons are diabetes mellitus, cirrhosis of the liver, osteopathy, recurring glomerulonephritis, and, rarely, malignomas. Transplantation frequency in the Federal Republic of Germany could be increased by more awareness of physicians and a better knowledge of the general public about the need for cadaver donors.

Diabetic glomerulosclerosis must be either a primary manifestation or a secondary consequence of the metabolic abnormalities of diabetes. Several earlier reports have attempted to support the former hypothesis by describing cases of pathognomonic renal lesions in nondiabetic subjects; however, the clinical and pathologic data in these reports are inconclusive. We have reviewed our experience at the University of Virginia Hospital with 447 percutaneous renal biopsies performed over a period of four years from July 1973 through July 1977. Of these cases, only two appeared to represent diabetic glomerulosclerosis occurring in nondiabetic subjects. Upon further investigation, one case provided to be light chain disease demonstrated by immunofluorescence staining. The other case, on repeat renal biopsy, proved to be membranoproliferative glomerulonephritis. We conclude that a diagnosis of diabetic glomerulosclerosis must be viewed with suspicion in nondiabetic subjects. Suspected cases should be labeled pseudodiabetic glomerulosclerosis and investigated further.

Diabetes mellitus was tentatively diagnosed in a black-footed ferret with polyuria, polydipsia, polyphagia, dehydration, and weight loss. Laboratory findings (marked hyperglycemia (724 mg/100 ml), glycosuria, and ketonuria) and the subsequent favorable response to insulin therapy confirmed the diagnosis. Although lesions were not observed in the pancreas, gross and histologic findings concomitant with diabetes mellitus included arteriosclerosis, with calcification of the aorta and other major vessels; mild necrotizing hepatitis; and mild proliferative glomerulonephritis. A perineal adenocarcinoma, with metastasis to an internal iliac lymph node, was an incidental finding. Special stains demonstrated adequate numbers of beta cell granules in the islets of Langerhans. Thus, the diabetes was apparently due to a lack of release of the synthesized insulin or to diminished effectiveness of the secreted insulin.

A total of 291 urine sediments from 255 patients with various renal or urinary tract diseases have been studied by phase contrast microscopy. Based upon morphological criteria, leucocytes were distinguished from renal epithelial cells and the white blood cells were classified either as mononuclear or polynuclear in 179 patients. The percentage of the different cell types varied considerably between and within the different diseases. The median values for polynuclear granulocytes were higher than 90% in bacterial renal or urinary tract disease and in polycystic kidney disease. In interstitial nephritis, nephrosclerosis and in renal transplanted patients the percentage of polynuclear granulocytes was somewhat lower, 76-85%. In diabetes, amyloidosis, tubular nephrosis (necrosis) glomerulonephritis, lupus nephritis and endemic benign nephropathy there were 14-66% polynuclear granulocytes. 29-33% mononuclear leucocytes were found in lupus nephritis and endemic benign nephropathy. The greatest proportion of renal epithelial cells was found in endemic benign nephropathy, namely 49%. 36% renal epithelial cells were found in tubular nephrosis (necrosis) and in glomerulonephritis. The technique is rapid and inexpensive. It facilitates differential diagnostics of urinary tract disease with pyuria.

Six patients without overt diabetes mellitus underwent renal biopsy for suspected glomerulonephritis. All were demonstrated to have diabetic glomerulosclerosis and subsequently were found to have abnormal glucose tolerance tests. Electron microscopy was critical in making the correct diagnosis in five of six patients. The reported cases represent 3% of a series of 200 patients who had a renal biopsy to evaluate possible glomerulonephritis. Renal manifestations of diabetes mellitus may antedate glycosuria and other more common presenting symptoms of this disease.

Lipoatrophic diabetes, known by pediatricians as Lawrence-Seip disease or Berardinelli lipodystrophy syndrome, is an infrequent condition of which approximately one hundred cases have been published to date. A case in a 24-year-old female with a fifteen-year follow-up is reported. Manifestations included acanthosis nigricans, generalized lipoatrophy, hirsutism, muscle hypertrophy, and intellectual impairment. Biologic tests revealed insulin-resistant diabetes mellitus with major diet-dependent type V hypertriglyceridemia. The patient had nephrotic syndrome (focal and segmental endocapillary proliferative glomerulonephritis without dense deposits). Phosphorus and calcium determinations were normal, as were the endocrinologic tests. Roentgenograms of the bones disclosed increased density of axial bones and large epiphyseal defects with increased bone density as determined by osteodensitometric studies. The bone manifestations of this syndrome have been documented but are often overshadowed by the severe metabolic alterations.

We devised a clinical test of renal metabolism based on the synthesis of guanidinoacetic acid from citrulline in the proximal convoluted tubule. Intravenous administration of a citrulline/creatine solution to rats with modified levels of renal glycine amidinotransferase activity revealed a strong correlation (r = 0.921) between this activity and urinary guanidinoacetic acid excretion. Citrulline (1.75 g) and creatine (1.50 g) were administered orally to healthy individuals and patients with chronic glomerulonephritis. In the healthy individuals, urinary guanidinoacetic acid excretion increased 5-fold by 2 h after dosing (15.1 +/- 2.2 vs. 2.8 +/- 1.1 mg/h). In the glomerulonephritis patients, blood clearance of citrulline decreased as the creatinine clearance decreased and urinary guanidinoacetic acid excretion also decreased. Of 56 patients with glomerulonephritis or diabetes mellitus, one had increased urinary guanidinoacetic acid excretion associated with an excess of adrenal androgens. This test appears a useful, noninvasive and simple method for examining the metabolic activity of the renal proximal convoluted tubules.
