The kidney is one of the target organs involved as a consequence of the systemic complications seen in drug abusers. This may manifest itself in one of the following forms: acute hepatitis with modest proteinuria (less than 2 Gm. per day); bacterial endocarditis with hematuria, azotemia, and a focal or diffuse glomerulonephritis; the nephrotic syndrome with focal mesangial sclerosis and diffuse interstitial nephritis often pursuing a fulminant course terminating in uremia; acute renal failure secondary to rhabdomyolysis and myoglobinuria; polyarteritis nodosa with renal involvement; and obstructive uropathy secondary to fungus ball in the urinary tract.

We report epidemiologic, clinical, laboratory, and biopsy findings in 14 cases of nephropathia epidemica. The patients were between 19 and 49 years of age. The onset of the disease was characterized by high fever, nausea, headache, backache, abdominal pain, proteinuria, oliguria, hematuria, and uremia. The symptoms subsided rapidly during the polyuria phase, which followed the oliguria stage. Because of renal failure, hemodialysis was required in eight cases. Edema of eyelids, conjunctival injection and hemorrhages, transitory myopia, and acute glaucoma were the most common eye abnormalities. Renal biopsy specimens showed glomerular changes, with mild swelling of the epithelial cells of Bowman's capsule, thickening of the basement membrane of glomerular capillaries, glomerular adhesions, inflammatory cell infiltration, leukocytoclasis and hemorrhages in the interstitium, and eosinophilic hyaline degeneration and vacuolization of the epithelial cells of the proximal tubuli.

Two patients with kidney transplants had hypertensive encephalopathy and rapidly progressive kidney failure 10 weeks and 18 months postoperatively. In one patient renal failure was associated with erythrocytosis. Absence of proteinuria, despite progressive renal insufficiency in both patients, suggested that these abnormalities were not due to rejection episodes. Subsequently, angiography proved that each of these patients had renal-artery stenosis. Surgical repair of this lesion increased creatinine clearance at least threefold, and the hypertension and erythrocytosis disappeared. Apparent "rejection" episodes in which there is no proteinuria should alert clinicians to the possiblity of renal-artery stenosis of the graft. Restoration of kidney function and amelioration of hypertension may follow revascularisation, even after many months of renal ischaemia producing severe uraemia.

Samples of renal tissue from 373 patients were examined for the presence of immunoglobulin E (IgE) by immunofluorescent techniques. Only trace to ++ amounts ( on a scale of ++++) were found in 20 patients: 4/9 with post-streptococcal acute glomerulonephritis (GN), 5/30 with GN associated with systemic lupus erythematosus, 3/20 with membranous GN, 1/4 with Goodpasture's syndrome, 2/18 with recurrent microhematuria and focal GN, 1/5 with hemolytic anemia and uremia, 3/73 with renal homografts, and 1/5 with dermatomyositis. No IgE was found in 18 patients with lipoid nephrosis, 8 of whom were being treated with prednisone, nor in 5 patients with focal glomerular sclerosis and the nephrotic syndrome. Serum IgE was measured in 9 of the 20 patients with glomerular deposits of this globulin. With one exception, levels of IgE were within the range generally considered to be normal. However, they were greater than the mean of this range in all but two and near the highest limits of normal in most. Neither the amounts of serum IgE nor the degree of proteinuria could be related to the intensity of stain for IgE in the glomeruli of these patients.

The results of low molecular weight (LMW) proteinuria test in urines of patients and suspect subjects in an endemic area of Balkan endemic nephropathy (BEN) in Yugoslavia are reported. An accordance between the positive LMW test and the clinical diagnosis of BEN has been found in more than 70%. The authors claim that LMW immunodiffusion test is a very useful procedure for detecting BEN and a great aid in the epidemiological work in the endemic field. The results of determining beta2-microglobuline (beta2m) in serums and urines by radioimmunoassay technique as well as counting of clearances of endogenous creatinine in healthy persons, "endangered" subjects in endemic area, and BEN patients without azotemia, with azotemia and uremia are reported. The group of 17 patients suffering of BEN without azotemia having slightly or more markedly lowered creatinine clearances showed higher serum and much higher urinary concentration of beta2m which are not in proportion with creatinine clearance. The results are interpreted so far as a consequence of the predominant tubular lesion in BEN. In groups of patients with azotemia and uremia no differences in beta2m handling have been found. The report has a preliminary character and requires further study.

NZB x OUW F1 hybrid mice were treated with thiamphenicol at 25, 50 and 250 mg/kg/day from the time of their first positive antinuclear antibody test until their death. Untreated mice fed the same diet served as controls with body weight, mortality and renal disease patterns conforming to published reports of the biology of the BW mice. Regular testing of urine and bloodm and detailed postmortem examinations showed (a) that with increasing drug dose levels heavy proteinuria was almost eliminated and blood urea concentrations significantly lowered; (b) that in treated and untreated mice moderate to severe anaemia developed, apparently unrelated to the degree of uraemia; (c) that changes in renal function did not correlate with antinuclear antibody activity, nor did the drop in packed cell volume correlate with fixed or free circulating antierythrocyte autoantibody positivity; (d) that histological analysis of renal changes showed that at the highest dose level glomerular lesions were minimal. Thus the prolonged treatment with thiamphenicol reduced the severity of the spontaneous renal disease and resulted in a significant extension of lifespan.

The character of hyperlipidemia was studied in rats with chronic uremia induced by subtotal nephrectomy--5/6 of the renal tissue was removed. 13 to 30 weeks after this operation the blood serum cholesterol and phospholipid concentration almost doubled. Hyperlipidemia was more pronounced in rats with high azotemia (blood urea nitrogen--BUN). No elevation of serum tryglycerides occurred. Total serum beta- and pre-beta-lipoproteins determined nephelometrically increased significantly only with the BUN level of over 80 mg%. Lipoprotein disc electrophoresis of the serum in rats with uremia demonstrated a distinct rise of alpha-lipoproteins and a slight--of beta-lipoproteins; postheparin lipolytic activity of the plasma was normal. Experimental rats displayed massive proteinuria, but hypoproteinuria was insignificant.

Renal disease, particularly glomerulosclerosis, is a major cause of morbidity and mortality in patients with juvenile-onset diabetes mellitus. Signaled by the onset of proteinuria after 15 or more years of insulin therapy, progressive renal insufficiency due to glomerulosclerosis terminates in uremia within five years. Although some patients have benefited from chronic dialysis programs, the outcome in uremic diabetics has been considerably better if successful renal transplantation can be accomplished. Extrarenal complications of diabetes mellitus and recurrence of diabetic lesions in transplanted kidneys have hampered the recovery and rehabilitation of transplant recipients. Other renal diseases encountered in juvenile diabetics are reviewed.

Data from a prospective study of the clinical course in 223 patients with systemic lupus erythematosus followed for 655 patient-years were analyzed by computer to determine the influence on frequency of infection of 1) corticosteroid dose; 2) azathioprine; 3) active disease, measured by new disease exacerbations, elevated ESR, hypocomplementemia, active urinary sediment, and proteinuria; 4) uremia; and 5) leukopenia. The frequency of all infections, and of bacterial and opportunistic infections specifically, increased progressively with increasing steroid dose. Azathioprine use, independent of steroid dose, did not account for an increased risk of bacterial, opportunistic, or nonspecific viral infections. Leukopenia did not predispose to infection, except possibly when associated with azathioprine-induced bone marrow suppression. Active renal disease, especially when manifested by abnormal urine sediment, was associated with an increase in infection frequency.

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.
