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.

With the aim of determining the relative prevalence of the diseases underlying chronic renal failure (CRF) in a large homogeneous black tropical population, the autopsy records of the Obafemi Awolowo University Teaching Hospital over a four year period were studied. Out of a total of 702 cases coming to autopsy during this period, 66 (9.4%) died as a result of CRF. The highest number of cases of CRF fell within the 31-40 year age group with a male/female ratio of 1.28:1. Chronic glomerulonephritis was responsible for 40.9% of cases, malignant nephrosclerosis 16.6%, benign nephrosclerosis 7.6% while endstage renal disease (ESRD) was responsible for 15.4%. A miscellaneous group of diseases was responsible for 19.7%, about half of which was due to chronic pyelonephritis. Rarer causes of CRF were diabetic nephropathy, multiple myeloma, systemic lupus erythematosus and analgesic nephropathy.

The Escherichia coli P fimbriae F71, F72, F9, and F11 from four cloned strains were purified, and polyclonal antisera were raised in rabbits. Cross-reactions of these antisera with eight different cloned and purified fimbriae were measured in an enzyme-linked immunosorbent assay. These antisera showed a reaction with the homologous fimbriae and also with most heterologous fimbriae. Monoclonal antibodies (MAbs) directed against the same four native fimbriae were produced by the fusion of spleen cells from immunized BALB/c mice with SP2/0 myeloma cells. The resulting four series of MAbs were also screened in an enzyme-linked immunosorbent assay with eight different cloned and purified fimbriae. Four different F71 hybridomas produced MAbs which recognized only epitopes on F71 fimbriae. Two F72 MAbs recognized epitopes on F72 and F9 fimbriae, whereas another F72 MAb recognized an epitope on only F72 fimbriae. Three MAbs raised against F9 reacted only with epitopes on F9 fimbriae. Six MAbs against F11 fimbriae could be divided into two groups: on the one hand two MAbs recognizing F11, pyelonephritis-associated pilus, Pap, and F72 fimbriae and on the other hand four MAbs recognizing F11 and "Clegg" fimbriae. None of the MAbs reacted with 1A or 1C fimbriae. In a hemagglutination inhibition assay it was shown that none of the MAbs produced inhibited the adhesive properties of homologous cloned strains.

Nine fatal cases of systemic mucormycosis observed in association with renal failure are described. Four patients were hospitalized for chronic renal failure as a consequence of chronic glomerulonephritis, myeloma kidney, chronic pyelonephritis, and polycystic kidney disease, respectively; and five patients presented with acute renal failure. The underlying causes in three of these five patients were gentamycin nephrotoxicity, acute gastroenteritis, and allograft rejection, respectively, and in the remaining two, acute renal failure was the result of extensive renal vascular and parenchymal invasion by mucor hyphae. Tissue invasion with mucormycosis was documented during life in two patients and at autopsy in seven patients. The infection was disseminated in five patients, and isolated pulmonary and rhinocerebral involvement occurred in two patients each. Our observations have shown that patients with renal failure are prone to develop mucormycosis, which carries a grave prognosis if therapy is not instituted in time.

Renal complications were studied in 81 autopsied patients suffering from multiple myeloma (47 male, 34 female, mean age 66.3 years). Kidney samples were examined for the presence of Bence Jones cast nephropathy, light chain deposition disease, amyloidosis, nephrocalcinosis, chronic urate nephropathy, acute renal failure, renal vein thrombosis, acute and chronic pyelonephritis, and tumorous infiltration of the kidney tissue. Lesions were graded under the light microscope as minimal, mild, moderate or severe. This grading and the corresponding serum creatinine levels were used to distinguish four groups: 1. morphologically and functionally intact kidney (40 cases); 2. kidney involvement with good renal function (10 cases); 3. kidney involvement with moderate chronic renal insufficiency (16 cases); 4. kidney involvement with chronic uraemia (15 cases). In patients with an impaired renal function (groups 3 and 4), Bence Jones cast nephropathy occurred most frequently (27 cases, 33%); all other complications were seen much less frequently. Among the 81 patients, two cases of kappa light chain deposition disease and three cases of amyloidosis were found. Although the semiquantitative morphology and serum creatinine levels displayed a good correlation, there were cases with marked histological changes but only a moderate impairment in renal function, suggesting that the drawing of functional conclusions from morphological changes of the kidney requires caution.

We studied renal histopathologic findings of 20 autopsy cases with multiple myeloma with particular attention to structural tubulovenous relationship. Urinary deposition in renal vein or lymphatics, which has been previously noted in pyelonephritis, obstructive uropathy, or vesicoureteral reflux was found in 14 cases. Four of 14 cases had unique tubulovenous communications designated as tubular prolase and tubular transformation of vein. Such communications were most frequently seen at the architectural weak point where the thin-walled interlobar vein and their tributaries adjoin the renal pyramid. Simultaneously, Tamm-Horsfall protein used as a marker for the location of urine was detected in renal vein. These changes had no significant correlation to morphologic severity of myeloma kidney or clinical manifestations of renal failure. Thus, tubulovenous communication producing backflow of urine into the circulation is frequently observed among myeloma kidney as well as other tubulointerstitial nephritis, but its clinical significance is unclear.

In connection with the analyses of 84 post-mortem examinations (47 men, 37 women, average age: 66.3 years) the author dealt with the renal complications of multiple myeloma. The signs of cylinder nephropathy, light-chain nephropathy, amyloidosis, nephrocalcinosis, urate nephropathy, acute renal insufficiency, renal vein thrombosis, acute and chronic pyelonephritis as well as the tumorous infiltration of the renal tissue have been sought for. The severity of the lesions were ranged into minimal, slight, moderate, and severe groups. On the basis of the semiquantitative morphological picture and the clinical data: 1. intact kidney (41 patients), 2. involvement of the kidney without azotemia (10 patients), 3. involvement of the kidney with azotemia (17 patients, serum creatinine level: greater than 177 mumol/l) and 4. renal involvement with chronic renal insufficiency associated with uremia (16 patients) were discerned. In the background of 33 cases (39%) with deteriorated renal function cylinder nephropathy was found most frequently (27 occasions) (32%). Every other complication occurred significantly less frequently e.g. amyloidosis or kappa-light-chain nephropathy occurred in 3 cases each.

A hospital-based case-control study of 153 multiple myeloma (MM) cases and 459 controls was conducted to evaluate the hypothesis that chronic or frequent infections or allergic and autoimmune diseases might be of higher prevalence in individuals who develop MM. Information was obtained by direct interviews of subjects. Controls were matched to cases on age, sex, race, and hospital. "Immune-stimulating conditions" included chronic infections such as pyelonephritis, urinary tract infections (UTIs), prostatitis, rheumatoid arthritis and other collagen vascular diseases, allergies, bronchitis, tuberculosis, cholecystitis, diverticulitis, and osteomyelitis. The overall odds ratio (OR) (odds of history of immune-stimulating conditions in cases versus controls) was 0.4 (95% confidence interval = 0.3-0.7) which suggested that cases had significantly less immune-stimulating conditions than did controls. The exposure rate for these conditions was high for cases (0.7) as well as for all control groups (0.8). These findings suggest that immune-stimulating conditions alone are not the causative factor in the etiology of MM, though they may play a role in the predisposed individual.

The role of the renal papillae in the pathogenesis of pyelonephritis and reflux nephropathy was studied by endoscopy and histology in adult autopsy kidneys. Compound papillae with a concave area cribrosa of the "reflux type" were found in greater frequency in adults than in children. Acute purulent inflammation in the renal parenchyma or coarse pyelonephritic scars were seen almost always overlying "refluxing" papillae or overlying papillae altered by papillary necrosis, obstructive atrophy and other changes of papillary shape. Intrapapillary tubular obstruction in early analgesic nephropathy, gout, myeloma and medullary cystic disease is an other factor favouring bacterial infection to occur. Without an underlying renal papillary damage renal injury attributable to urinary infection seems to be rare.

In contrast to healthy persons, microvillous antigens of the proximal tubule were excreted at an increased rate in patients with kidney diseases as could be shown using specific antisera against brush border (BB) fragments (tissue-proteinuria, histuria). These urinary membrane components were immunologically completely identical with those antigens prepared from isolated kidney cell membranes. A glycoprotein of 240 000 dalton, containing mannose and N-acetylglucosamine was identified as a major immunoreactive constituent of the brush border surface and found to be part of a multienzyme complex. BB-antigens were excreted in urine of patients with glomerulonephritis, hypertension, pyelonephritis, multiple myeloma, after operations, after kidney transplantation, under cytostatic treatment, and after administration of radiopaque agents. Histuria of BB-antigens was significantly higher in patients with multiple myeloma and Bence-Jones-proteinuria compared to those patients where no Bence-Jones L-chains in urine became apparent. Selective kidney angiography and intravenous urography caused a significantly higher output of BB-antigens as compared to the control period (2 p less than 0,005). In a volunteer model, on the basis of BB-histuria, a different nephrotoxic potency of cephalosporins and aminoglycosides arose. In addition, beside soluble BB-antigens, also high molecular weight membrane vesicles were discovered in urine of patients after cytostatic treatment (cis-platinum), after x-ray contrast media, and after kidney transplantation. Both, soluble as well as supramolecular membrane vesicles were isolated from urine applying immunospecific affinity chromatography (anti-BS-agarose beads). Labeled antisera directed against the vesicle material of urine revealed a specific immunofluorescence of cortical tubule only.(ABSTRACT TRUNCATED AT 250 WORDS)
