Kidneys obtained by nephrectomy from 85 patients with chronic nephropathy were examined by bacterial culture and by immunofluorescence for a content of E. coli antigen. A panel of 10 E. coli 0-antisera, representing the strains most commonly causing urinary tract infection, and antiserum against common enterobacterial antigen (CA), were used. Bacteria could be cultured from the nephrectomy specimens in 24 cases, mainly in cases of obstructive chronic pyelonephritis, analgesic nephropathy and congenital renal disease. By immunofluorescence, type-specific 0-antigen was found in whole bacteria and amorphously in macrophages, CA only in whole bacteria. Whole bacteria could be visualized in 12 cases, macrophages only in two cases. Amorphous bacterial antigen was no observed outside phagocytizing cells. On the basis of these results, it seems unlikely that progression of the renal lesions in chronic renal disease is due to persistant bacterial antigen in the absence of viable bacteria. Chronic pyelonephritis, defined as an interstitial nephritis due to the effects of bacterial infection in the renal parenchyma and pelvic mucosa, appears always to be a secondary manifestation following obstruction or primary renal disease, such as analgesic nephropathy or congenital renal disease.

In 64 patients who had undergone renal transplantation, later on followed by bilateral nephrectomy, bacterial growth culture was performed from the original kidneys. The presence of bacteria in the nephrectomy specimens was compared with the occurrence of significant bacteriuria before transplantation and in the period between transplantation and nephrectomy. Bacteria could be cultured from the nephrectomy specimens of 18 (28.1 per cent) of the patients, almost exclusively confined to cases of obstructive chronic pyelonephritis, analgesic nephropathy and congenital renal disease. Before transplantation, bacteriuria had been recorded in 34.4 per cent of the patients, most frequently in the three groups of diseases just mentioned. Between the transplantation and nephrectomy, bacteriuria occurred in 75.0 per cent of the patients. Patients with E. coliuria before transplantation were particularly liable to have E. coliuria also after the transplantation and to E. coli in the nephrectomy specimens, whereas patients in whon E. coliuria did not occur until in the post-transplantation period were less susceptible to E. coli infection involving the kidneys. Probably the presence of bacteria in the nephrectomy specimens is related to the primary disease rather than to immunosuppressive and antiobiotic agents administered in the post-transplantation period.

25 (30%) out of 85 adult patients with endstage renal disease were found to have vesicoureteral reflux. In group I with 15 patients renal insufficiency was caused by kidney disease alone. In a second group 8 patients had the diagnosis chronic pyelonephritis with well documented history of urinary tract infection. In a third group 2 patients have megaloureter-megalocystis syndrome. There was no case of uncomplicated, sterile reflux in the second and third groups, which seems to be a rare cause of renal insufficiency.

The pattern of renal disease and its basic principles of management are essentially the same in the tropics as in the temperate environment. Glomerulonephritis and pyelonephritis with concomitant hypertension account for most cases of renal failure. Malaria is now well recognised as a cause of the nephrotic syndrome. Economic and manpower factors dictate a conservative approach to therapy. Maintenance haemodialysis and renal transplantation are not realistic in the present context, having regard to the order of priorities in health care delivery.

Five patients who presented with acute renal failure in association with urinary tract infection are reported. Renal function improved rapidly on antibacterial therapy and no alternative cause for acute renal failure could be identified. None had previously been known to have renal disease but three of the five had taken considerable amounts of analgesics. The unusual severity of renal functional impairment resulting from urinary tract infection in these patients is unexplained but may relate to previous analgesic abuse and/or delay in treatment. Since acute non-obstructive pyelonephritis may result in severe reversible renal failure, this diagnosis must be considered in patients presenting with acute uraemia.

Intranasal administration of DDAVP (1-deamino-8-D-arginine vasopressin), a synthetic analogue of vasopressin, followed by measurement of urine osmolaity 6 h afterwards, represents a convenient, reliable and simple method for the estimation of renal concentrating capacity in children. The DDAVP-test is as accurate and reproducible as the water deprivation test, irrespective of the degree of concentrating capacity. Mean urine osmolality after DDAVP in children without renal disease was found to be 984 +/- 218 mosmol/kg water (m +/- 2 SD). In children with recurrent pyelonephritis, urine osmolality after DDAVP was decreased. The values were significantly lower with bilateral changes than with unilateral changes of chronic pyelonephritis in the i.v. urograms. In chronic pyelonephritis the concentrating capacity appears to be earlier impaired than other parameters of renal function.

A case of unilateral reflux nephropathy treated by initial ureteral reimplantation and subsequent nephrectomy is reported. Pathologic examination of the resected kidney showed unsuspected proliferative glomerulonephritis. The relationship of chronic atrophic pyelonephritis, as seen in reflux nephropathy, and glomerulonephritis is discussed to emphasize that reflux nephropathy does not exclude the presence of other renal disease that may complicate the long-term care of the patient.

Acute renal failure occurred during indomethacin therapy in a patient with chronic pyelonephritis. Urinary prostaglandin E2 levels were diminished but returned to normal after discontinuation of drug therapy and recovery of renal function. Prostaglandins may be critical for the integrity of renal function, and the use of prostaglandin inhibitors such as indomethacin and other nonsteroidal anti-inflammatory drugs may be deleterious in patients with underlying renal disease.

Cellular immune reactivity was studied in 78 patients with various forms of renal disease by skin testing with four recall antigens and a lymphocyte transformation test with tuberculin PPD and leucoagglutinin. Patients with S-creatine greater than or equal to 230 micromol/l as well as those with chronic pyelonephritis who had S-creatinine values below 230 micromol/l had significantly lower skin reactions than the controls to streptokinase-streptodornase, parotitis and PPD. Glomerulonephritic patients with S-creatinine values below 230 micromol/l had normal skin reactivity. Lymphocyte transformation tests showed decreased reactivity only in patients with S-creatinine level greater than or equal to 230 micromol/l. The results suggest an association of chronic pyelonephritis with a defective efferent, nonspecific arm of cellular immunity.

Follow up studies in 19 diabetic patients with manifestation in the youth. Proteinurie within few years; later on nephropathy: 7 cases with glomerulosclerosis, 8 with arteriolosclerosis, 3 with pyelonephritis and 1 with chronic glomerulonephritis. In all cases retinopathy, very often coronarsclerosis, seldom peripheral and cerebral sclerosis. 14 patients died, mostly in young age in consequence of nephropathy. Proteinurie is a malignant symptom of diabetic angiopathy; in contrast to the retinopathy.
