A series of 29 cases of amyloidosis of the alimentary tract is reported. Five cases (17%) were primary amyloidosis; 14 cases (48%) were amyloidosis secondary to other diseases (such as chronic inflammatory and neoplastic diseases); 10 cases (35%) were amyloidosis of the heredo-familial type connected with Familial Mediterranean Fever. In 23 patients (79%) the diagnosis was established by biopsies, and in 6 more cases on autopsy. Gastrointestinal involvement was found in all age groups. Gastro-enterologic complications observed in the present series include: diarrhea, malabsorption, ileus and gastrointestinal bleeding. In addition other conditions such as jaundice (3 cases), esophagitis and acute hemorrhagic pancreatitis were observed. In 22 patients proteinuria was observed and in 13 patients the nephrotic syndrome. Among 17 patients, in 11 the clinical picture before death was that of terminal renal failure. The survival after diagnosis among 14 patients reached 4 years in 9 cases, and 19 years in one case. The diagnostic value of the rectal biopsy is emphasized.

The effect of long-term administration of interferon in New Zealand Black and New Zealand Black/New Zealand White F1 hybrid mice was studied. Treatment with moderate doses of interferon (10(4) units, five times weekly for 8 weeks) did not depress murine leukemia virus gp69/71 levels in serum and spleen, nor p30 levels in the spleen. Interferon given at 10(5.1) units (three times weekly for 37 weeks) caused an increased incidence of anti-erythrocyte antibodies in New Zealand Black mice. Finally, the hybrid mice given interferon at 10(6.0) units (three times weekly for 33 weeks) had increased renal immune complex deposits and increased incidences of proteinuria and anemia.

Metabolic balance studies were carried out in 17 unselected patients with acute myeloid leukaemia. Widespread metabolic disturbances were observed. Serum Na fell below 135 mmol/1 in 14 patients (82%) and 11 patients (64%) developed hypokalaemia. An increased osmolal clearance caused by a release of electrolyte and blast cell waste (i.e. urea, urate, etc.) during chemotherapy appeared to be the principle cause of natriuresis and hyperkaluria. Seven patients had proteinuria before and eight others developed it during antileukemic therapy. Nine patients (53%) developed proximal renal tubular dysfunction with aminoaciduria, hyperphosphaturia and incomplete reabsorption of urate. No significant relation was found between this widespread glomerulo-tubular dysfunction and lysozymuria. We suggest that antileukaemic drugs release unidentified substances from blast cells which are toxic to the kidney. Metabolic alkalosis in six patients (35%) was probably related to volume depletion and hypokalaemia, while two patients developed acidaemia with the onset of renal failure. Hypocalcemia in seven patients (41%) had a multifactorial basis: hyperphosphaturia, septicaemia, malnutrition and cytotoxic drugs were among the probable causes.

We produced an autoimmune glomerulotubular nephropathy in Swiss-Webster mice using human glomerular antigen in Freund's complete adjuvant. The disease is associated with circulating antibody to both mouse and human glomerular basement membranes (GBM) and tubular basement membranes (TBM). All mouse IgG subgroups are deposited initially in a linear pattern along the GBM and TBM. IgG deposition remains linear, while that of the other subgroups assumes a granular GBM pattern with continued linear TBM deposits. Despite tissue deposition of antibody capable of C-3 fixation, no C-3 is found in vivo along the GMB or TBM, nor is there C-3 fixation in vitro. This appears to be related to spatial limitations of IgG molecule attachment to basement membranes. A unique ultrastructural lesion of the GMB developed, characterized by periodic expansions of the lamina rara externa to form a beaded pattern. Eluate of nephritic kidneys contained all subgroups of IgG, but mainly IgG1 fixed in vitro to mouse kidney and in vivo when injected intravenously into normal mice. Fixation of other IgG subgroups in vivo may have resulted from antibody formation to abnormally formed GBM, thereby accounting for the peculiar ultrastructural findings and tissue fixation characteristics of the eluted immunoglobulin. Abnormal proteinuria without glycosuria or lysozymuria developed in test animals as compared to controls. Our model is similar in certain aspects to previously described models of Stebley nephritis, but differs because of the total involvement of TBMs, unique ultrastructural lesions, and dissimilarity to other reports of this model in mice.

A white female infant who developed a sudden onset of gross hematuria and proteinuria at 3 months of age was referred for evaluation of nephrotic syndrome at 6 months. Laboratory investigations revealed severe Coomb's negative hemolytic anemia, leukopenia, thrombocytopenia, hypocomplementemia and elevated anti-nuclear antibody titer and DNA antibodies. Renal biopsy showed a membranous type of morphology. She was also found to have chromosome abnormalities. She had an eventual favorable response to steroid therapy. Systemic lupus erythematosus (SLE) is rarely seen in young infants and the renal expression of the disease found in our case has never been reported.

Oral antidiabetics are given for preference to adult diabetics who do not need insulin. Biguanides are particularly indicated for adipose diabetics, sulphonamides for those of normal weight. Phenformin must not be used in the presence of renal insufficiency and severe liver diseases because of the high risk of lactacidosis. Oral antidiabetics should not to be given during pregnancy. With oral treatment of diabetics under the age of 30, proteinuria, peripheral vascular diseases and disturbances of fat metabolism occure more frequently while retinopathies, coronary diseases, peripheral neuropathies or infections of the urinary tract cannot be influenced orally, nor by insulin nor by a combination of the two. The i. v. lipid tolerance test is always pathological even in apparently well-adjusted orally treated diabetics. On the other hand it is normal even in less well adjusted insulin therapy. More epidemiological investigations should be carried out in order to be able to assess clearly the longterm effects of oral antidiabetics.

We compared the effects of netilmicin and tobramycin on renal function and histology in dogs. Separate groups, each containing 5 dogs, received control injections, or either netilmicin or tobramycin at doses of 25, 50, or 75 mg per kg of body weight per day for 14 days. Renal function decreased markedly only in the group receiving the 75-mg tobramycin dosage; the serum creatinine levels rose from 1.0 +/- 0.1 to 3.6 +/- 0.9 mg per 100 ml (P less than 0.05) and the endogenous creatinine clearance fell from 42.5 +/- 9.4 to 7.8 +/- 2.2 ml per min (P less than 0.05). Dogs in this group developed glycosuria, proteinuria, and polyuria, and three died before the end of the study, probably from neuromuscular toxicity. Peak drug levels were stable when renal function was normal, but increased when renal failure occurred. Light microscopic changes occurred in all groups receiving either drug, but were most severe in the high-dose tobramycin group. Ultrastructural changes were similar in all groups and identical to changes produced by gentamicin. These results show that, on a weight basis, netilmicin is less nephrotoxic than tobramycin in dogs.

Toxemia in pregnancy (preeclampsia)is characteristerized by a combination of at least two of the following clinical symptoms: hypertension, edema, and proteinuria. In three successive trials over three consecutive years, the dietary intake of a selected number of young pregnant women attending a Maternal and Infant Care Program at Tuskegee Institute were evaluated for total lipids, individual fatty acids, and cholesterol. Women with toxemia or with any of the individual symptoms were identified and women without toxemia or these symptoms served as controls. Results were variable from repetition to repetition in all but the toxemia group and the edema group. The consumption of total lipids and cholesterol was significantly greater in all three trials by both the toxemia and edema groups. Also, total saturated, monounsaturated, and polyunsaturated fatty acids were eaten in greater amounts. The greatest differences were in palmitic acid, stearic acid, oleic acid, and linoleic acid. The proportion of unsaturated fatty acids consumed in all groups was very low. All differences could be attributed primarily to breakfast and dinner meals and were found in the milk, meat, and egg food groups. Although satistical correlations were found between lipid intake and toxemia of pregnancy any specific relationship between the two is still unclear.

Thirteen patients with systemic lupus erythematosus (SLE) who had normal results of urinalysis, absence of proteinuria, and normal serum creatinine values underwent renal biopsy. Three of 13 patients had diffuse proliferative glomerulonephritis (group 1). Biopsy specimens showed segmental fibrinoid necrosis, diffuse mesangial hypercellularity, and substantial immunoglobulin deposition. Group 2 comprised those patients whose histologic findings did not portend a poor prognosis. Four had mesangial proliferative glomerulonephritis, three had focal proliferative glomerulonephritis, and three had minimal mesangial widening. The values of inulin clearance in group 1 did not differ significantly from those in group 2. Patients in group 1 had a mean age of 19 years, a value significantly lower than in group 2 (41.8 years). Review of previous reports also supports the thesis that this phenomenon is age related. Our study underscores the importance of renal biopsy in patients with SLE despite the absence of clinical evidence of renal involvement, particularly in patients under 30 years of age.

We have investigated the pathogenesis of glomerular hypercellularity seen in acute serum sickness nephritis induced in rabbits with bovine serum albumin (BSA). The increase in cellularity began with the first stages of immune clearance of BSA, with a peak cellularity occuring at the time of onset of proteinuria. Although there was a significant increase in the fraction of glomerular cells incorporating [3H]thymidine, first seen at the onset of proteinuria, this increase occurred too late and was too small to explain the observed rate of increase in glomerular cellularity. On the other hand, a striking monocytic infiltration of the glomeruli was documented by electron microscopy and by staining for nonspecific esterase. This monocytic infiltration paralleled the observed course of glomerular hypercellularity and was quantitatively sufficient to explain the total increase seen. It appears, therefore, that glomerular hypercellularity seen in this model is principally a result of monocyte infiltration.
