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.

In a comprehensive survey the diagnostic and therapeutic problems of pyelonephritis and glomerulonephritis are discussed. The importance of thorough nephrological diagnostics is pointed out. The first section of the paper describes the diagnostic procedures such as x-ray and laboratory work (tubular proteinuria, antibody-coated bacteria) and the chemotherapy in pyelonephritis. The second part deals with glomerulonephritis, the aspects of histological classification, etiology, pathogenesis, diagnostic principles, prognosis, and results of therapy with penicillin G (acute form), corticosteroids, azathioprine, indomethacin, and cyclophosphamide.

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.

In order to assess to what extent glomerular or tubular function is involved in the renal handling of amylase and the lysozyme to creatine clearance ratios (CAm/CCr and CLys/CCr) were evaluated in 22 healthy volunteers and in 71 patients with different renal diseases. In normal controls, the mean CAm/CCr was 2.55 +/-1.54 SD, with an upper normal limit of 5.56. A normal ratio was found in patients with glomerulonephritis, with or without a nephrotic syndrome, and in patients with pyelonephritis. A significantly elevated ratio (P less than 0.001) was instead found in patients with uremia and in patients with uremia and in patients with either chronic or acute tubular damage. The CLus/CCr ratio was elevated in all the groups, except in patients with glomerulonephritis and minimal proteinuria. These results show that in humans, as in animals, the amylase filtered load undergoes partial tubular reabsorption. In renal diseases, an increase of the CAm/CCr is caused by either a marked reduction of functioning nephrons or a severe tubular damage, while the glomerular permeability does not seem to be involved. Some other mechanism is probably involved in the elevation of the CAm/CCr during acute pancreatitis.

In a review of 45 patients who started receiving hemodialysis (HD) after the age of 70 years (mean, 75 years), compared with a control of 70 HD patients (mean age, 42 years), the two-year survival for elderly patients was 42% and 58% for controls. In the elderly group, age did not correlate with survival. Nine elderly patients were over 80 years old and had a two-year survival of 41%. The elderly patients had a significantly lower mean predialysis blood pressure (BP) (142/73 +/- 3/1 mm Hg) than the controls (158/88 +/- 2/1 mm Hg) (P less than .001). Only 13% of the elderly patients received antihypertensive medication, compared with 41% of controls (P less than .01). The BP showed a significant negative correlation with age in both elderly ( r - .41, P less than .01) and control (r = .35, P less than .001) patients. Glomerulonephritis was less common in the elderly (9%) than control (31%) groups, and pyelonephritis was more common (29% vs 16%).

Thirty six patients with chronic glomerulonephritis, 35 -- with chronic pyelonephritis, 5 -- with diffuse glomerulonephritis with systemic lupus erythematosus and 60 healthy subjects were examined with the method by sedimentation with 3.5 per cent solution of polyethyleneglycol for the determination of circulating immune complexes. The average value for the healthy subjects is X = 0.123 +/- 0.047 mg/ml. The average value plus two standard deviations = 0.217 mg/ml is accepted as normal in healthy subjects. An elevated level of circulating immune complexes is found in 60 per cent of the patients with lupus nephritis and 25 per cent of the patients with chronic glomerulonephritis. The average values for the last two groups are X = 0.475 +/- 0.554 mg/ml and X = 0.184 +/- 0.185 mg/ml respectively. Whereas in the patients with lupus nephritis the values for the single patients are considerably over the adopted norm, in patients with chronic glomerulonephritis, in the majority of the cases, they are about its upper limit.

The kinetics of penicillin and semicillin was studied in 80 children at the age of 5 to 14 suffering from glomerulonephritis and pyelonephrities. The Bertolotti penicillin test revealed an isolated or associated (with lowered glomerular filtration and function of the osmotic concentration) decrease in the secretory function of the proxymal nephron in the patients without the signs of chronic renal insufficiency. The results of the study on the pharmacokinetics of simicillin indicated definite regularities in its excretion with urine as dependent on the period of its use and the state of the renal function. When semicillin was used in therapeutic doses, its concentration in urine exceeded the MIC with respect to all bacteria isolated from the urine specimens of the patients with pyelonephritis. Control of the antibiotic blood levels in children with kidney diseases at the stage of chronic renal insufficiency is necessary for choosing the optimal dose and intervals between the drug injections.

Voided urine samples from healthy persons and patients with glomerulonephritis, chronic pyelonephritis and bacterial urinary tract infection were examined. Urine from healthy persons contained 0-12 granulocytes/mm3, 0 mononuclear leukocytes/mm3 and -2 renal epithelial cells/mm3. Urine from patients contained a larger number of cells/mm3 than did urine from healthy persons. With differential counting of granulocytes, mononuclear leukocytes and renal epithelial cells patients with glomerulonephritis could be separated from patients with chronic pyelonephritis or bacterial urinary tract infection. The percentage values obtained at differential counting were not correlated to age, sex, total number of cells/mm3, proteinuria or serum creatinine level.

In patients with chronic renal failure due to glomerulonephritis, pyelonephritis or polycystic kidneys the urinary clearance of free chloramphenicol (C(CHL)) was depressed proportionally to GFR (C(In)). The ordinate intercept of the regression line of C(CHL) on C(In), however, consistently was positive (+3 to +5 ml/min). The fractional excretion of chloramphenicol in renal failure increased from its normal value of 50 percent as an exponential function of the decrease of GFR, and as a linear function of the fractional excretion of water or of sodium. Dietary sodium restriction had no influence on C(CHL) in the patients, while water diuresis, in normal subjects, enhanced the urinary excretion of chloramphenicol. The data suggest that chloramphenicol is reabsorbed by back-diffusion and that increases of the rate of flow of urine and tubular fluid prevent back-diffusion.

Following a method described by Mitch and co-workers in patients with chronic retention of substances normally contained in the urine the reciprocal values of serum creatinine determinations were figured in the long-term course. Of 22 patients 20 showed an extensively linear decrease of 1/creatinine in the period, independently on the fact, whether a pyelonephritis, glomerulonephritis or cystic kidneys were the basis disease. The correlation calculation confirms with a mean correlation coefficient of 0.842 in a dispersion of +/- 0.106 the connection mentioned so that possibilities of the prognosis for the moment of the dialysis and for an objective judgment of the therapeutic success are outlined.
