A nephrotic syndrome caused by immune-complex glomerular disease was diagnosed in a 4-year-old male Great Dane. The syndrome was characterized by proteinuria, hypoproteinemia, hypoalbuminemia, hypercholesterolemia, and subcutaneous edema. Renal biopsy revealed segmental membranous glomerular disease. The edema underwent complete remission 18 days after admission. Two months after admission, there was no clinical or laboratory evidence of glomerular disease. Periodic reevaluation of the dog during the next 2 years revealed recurrence of proteinuria, but no other clinical or laboratory abnormalities. Serial renal biopsies revealed persistence, but no appreciable increase, in the severity of the segmental membranous glomerular disease. The natural course of the nephrotic syndrome and immune-complex glomerular disease has been associated with unpredictable variability. It was concluded that the widespread use of corticosteroid or immunosuppressant therapy in dogs with immune complex glomerular disease should be withheld until the natural course of the disease has been evaluated in a significant number of patients and until the results of well-controlled clinical studies confirm or deny their therapeutic value.

Detailed studies of protein metabolism were undertaken in a patient with pellagra and hypoproteinemia associated with the carcinoid syndrome both before and after treatment. The synthesis of albumin improved from 82 mg per kg per day to 135 mg per kg per day with little change in the daily excretion of 5-hydroxyindole acetic acid. After treatment with nicotinamide the patient made good progress with a complete resolution of the signs of pellagra and protein malnutrition. These results support the hypothesis that a reduced availability of the essential amino acid L-tryptophan may limit the synthesis of albumin and nicotinic acid in patients with the carcinoid syndrome who become anoretic.

Operative intervention in patients with unrecognized and untreated amebomas or acute fulminating amebic colitis may result in severe complications. Nevertheless, certain clinical presentations of intestinal amebiasis require surgical procedures varying from drainage of an abscess to a subtotal colectomy. If, in patients with acute fulminating amebic colitis, the signs or symptoms of intraperitoneal or impending perforation develop, unremitting diarrhea associated with anemia and hypoproteinemia continues, or localized abscsses fail to improve with chemotherapy, operative intervention is indicated. Complications of amebomas that require operative intervention include failure to respond to chemotherapy, perforation, hemorrhage, ulceration, stricture or fistula formation and obstruction. Anti-amebic chemotherapy can reduce intestinal complications so elective operative procedures should be delayed to allow time for adequate treatment.

The authors report two cases of exsudative enteropathy characterised by the existence of oedema of the lower limbs associated with hypoproteinemia and marked lymphopenia with disturbances of the P.V.P. test. In both cases lymphography demonstrated major abnormalities with obvious obstruction in one case, and signs of slowing of lymph flow with appearances of dysplasia in the other. Surgery permitted us in one case, to discover a calcified lymph node probably due to tuberculosis. The etiology of these cases is discussed and seems to be mainly related to abnormalities of the lymphatic system. A low fat diet and administration of medium-chain triglycerides, gave an undoubted improvement when the treatment was followed by the patient. These two cases illustrate well the difficult diagnostic and therapeutic problems sometimes raised by syndromes of exsudative enteropathy, in particular owing to the many possible causes.

Intravenous administration of the aminonucleoside of puromycin produces the nephrotic syndrome (proteinuria, hypercholesterolemia, hypoproteinemia and edema) in rats. This model is very similar to human nephrotic syndrome caused by various disease states. The current study was designed to assess the nature of urinary lipoproteins in the urine of nephrotic rats, including studies related to the urinary loss of the "activator" apolipoproteins for the lipoprotein lipase-triglyceride interaction. Sprague-Dawley rats were given a single intravenous injection (10 mg/100 g) of puromycin aminonucleoside. Plasma and urine were collected before and 7, 18, 29, 36, and 53 days after injection of puromycin. Urine was fractionated in the preparative ultracentrifuge into density (d) fractions less than 1.006 (very low-density lipoproteins), d = 1.006-1.063 (low-density lipoproteins), and d = 1.063-1.210 (high-density lipoproteins--HDL). The cholesterol, triglyceride, phospholipid, and protein content of these fractions was analyzed. Lipoprotein electrophoresis was performed in agarose agar. Urine from normal and nephrotic rats was added to an in vitro system containing lipoprotein lipase and triglyceride. The free fatty acids (FFA) liberated were then measured as an index of urinary activator property on this system. Measurable urinary lipoproteins were present only on days 7 and 18 after induction of the nephrotic syndrome. Coelectrophoresis of these urinary lipoproteins with rat plasma revealed a single band having alpha- (HDL) electrophoretic mobility. The total mean protein content of day-7 urinary lipoproteins (64.3%) was greater than the content of plasma HDL (52.9%). The protein content of urinary lipoproteins also increased with time. When day-7 and day-18 postinjection urine at nephrotic rats was added to the lipoprotein lipase system, the hydrolysis of triglyceride yielded a mean of 0.320 and 0.235 muEq FFA/ml/20 min, respectively. Control rat urine yielded 0.030 muEq FFA/ml/20 min and 0.000 muEq FFA/ml/20 min 7 and 18 days after injection of normal saline, respectively. It is inferred that in this experimental model (1) high-density lipoproteins are probably excreted in the glomerular filtrate, (2) alterations in the composition of the excreted lipoproteins may occur during their passage through the nephron. The possibility that only a selective portion of the HDL spectrum is excreted into the glomerular filtrate cannot be excluded. It is suggested that the urinary or renal loss of this functionally important lipoprotein may contribute to the pathophysiology of hyperlipoproteinemia in the nephrotic syndrome.

A case of 21 year old male with neuropathy caused by renal insufficiency was present. He had taken bromate (mixed powder of potassium bromate and sodium bromate) for the purpose of suicide and suffered from acute renal insufficiency and hard of hearing. Renal dysfunction improved gradually by peritoneal dialysis and hemodialysis. However, on the 32th day after the onset, burning pain appeared in the bilateral feets. Following this, he began to complain of the disturbances of superficial and deep sensory below the ankle jerks and the weakness of his toes. Considering the clinical features, we supposed that the disturbance of the peripheral nerve was caused by uremia due to taking bromate. N. suralis was biopsied on the 80th day after the onset and examined electron microscopically. Electroscopical findings was as follows. Degeneration of the Schwann cells and irregularity or destruction of the myelin sheaths were observed. The axoplasm of the myelinated nerve fiber were relatively preserved as compared with the changes of the myelin sheaths. In the unmyelinated nerve fibers, cavity formations were observed. The findings of regeneration were not observed. From the electron microscopical findings, we speculate that the changes of the Schwann cells and the myelin sheaths are primary resulting from the disturbance of the metabolism of the Schwann cells. We speculate that anemia and hypoproteinemia caused by bromate disturbed regeneration.

Critically ill or injured patients often have impaired cardiovascular function. Since low ionized calcium levels can cause such changes, serum calcium and urine calcium were measured in a prospective study involving 28 criticially ill or injured patients and 16 normal controls. Serum protein levels were also measured to calculate "corrected" total calcium levels. Ionized calcium levels are difficult to measure. Since ionic hypocalcemia is thought to increase the "nephrogenous production" of cyclic AMP, cyclic AMP levels were measured in the blood and urine of these patients and the "nephrogenous" cyclic AMP calculated from the creatinine clearance. The mean total serum calcium in these patients was 7.7 +/- 0.8 mg/dl (S.D.). This was significantly lower (p less than 0.001) than our controls (9.6 +/- 0.6). When corrected for hypoproteinemia, the mean serum calcium (8.7 +/- 0.8) was still significantly lower (p less than 0.005) than control (9.4 +/- 0.5). The mean urine calcium excretion in the patients (56 +/- 66 mg/100 ml G.F.R.) was lower, but not significantly so, than in the controls (84 +/- 44 mg/100 ml G.F.R.). The "apparent nephrogenous" cyclic AMP in the study group was 2,731 +/1 1,451 pm/ml/100 ml G.F.R. The nephrogenous cyclic AMP had a negative correlation (r =-0.45) with "corrected" total calcium levels. Thus "total," "corrected" total, and "ionized" calcium levels appear to be reduced in the majority of critically ill or injured patients studied. The clinical implications of these findings and the potential value of serial cyclic AMP determinations in blood and urine will be discussed.

The benefits of parenteral feeding need no longer be emphasised. However, qualitative and quantitative food supplements raise a certain number of difficulties which should be better known. Infection is the most frequent complication. It may be avoided by strict aseptic precautions throughout parenteral feeding. Hypoglycemia is a major risk owing to the possible consequence. Hyperglycemia and its consequence of osmotic polyuria is more frequent and should be controlled to avoid loss of water and salt. Complications due to the use of lipid emulsions are exceptional when soya oil is used. Hypophosphoremia should be corrected by increasing phosphate intake. Hypocalcemia is common; it is often associated with hypoproteinemia and sometime a low calcium intake, vitamin D deficiency or a sudden increase in phosphate intake. Vitamin deficiencies, hypomagnesemia, and oligo-element deficiencies should be correcty by appropriate supplements.

The induction of nephrotoxic nephritis in rats with rabbit antibodies preparation results in proteinuria, hypoproteinemia and hyperlipidemia with little glomerular lesions. A study of some hydrolases in cortex and medulla on one hand and glomerular and tubules on the other, showed changes in the activities of following enzymes. 1) A 20-30 % decrease in Na+, K+ dependent ATP-ase in whole kidney. 2) A 20 % decrease in beta-galactosidase activity in glomerular and medulla. 3) A 20 % increase of arylsulphatase A activity in tubules. These results are discussed in the light of the present knowledge of sulphatide metabolism in kidney.
