A drug addict with staphylococcal endocarditis treated with methicillin, who developed massive proteinuria and acute nephritic syndrome is described. Discontinuation of methicillin therapy and appropriate antibiotic treatment of endocarditis led to clinical improvement, emphasizing the need to promptly discontinue potential nephrotoxic agents when abnormalities in renal function appear. The clinical course and results of renal biopsy studies suggest multiple causes of the renal lesions in this patient.

Twenty-eight patients with demonstrated chronic renal vein thrombosis were studied. In seven, only small venous channels were involved; in 21, both small and large veins were thrombosed. A constellation of findings occurred with such frequency in these patients that we believe it virtually diagnostic of renal venous obstruction. These findings include the nephrotic syndrome, great variability in proteinuria and glomerular filtration rate, pulmonary embolization, sterile pyuria, hematuria, hyperchloremic acidosis, decreased renal tubular threshold for glucose and increased fibrin degradation products. These findings are an indication for definitive angiographic and biopsy procedures. Prolonged anticoagulant therapy was generally very effective.

The morphology of the placental bed spiral arteries was studied in 68 pregnancies complicated by fetal growth retardation and in 40 pregnancies with a normally grown fetus. When the birth weight was normal the extent and depth of physiological vascular changes were normal except in those pregnancies complicated by pre-eclampsia. When the birth weight was low and the mothers were normotensive the extent and depth of physiological vascular changes were either normal or restricted, and in all patients with hypertension and a baby with low birth weight the physiological changes were restricted to the decidual segments of the spiral (uteroplacental) arteries. Acute atherosis was only found in pregnancies complicated by hypertension, particularly if there was proteinuria. We do not believe that there exists an arteriopathy which is common to hypertensive and normotensive pregnancies complicated by fetal growth retardation.

Two patients who presented with ulcerative colitis are described. Both were found to have evidence of IgG monoclonal gammopathy and Bence-Jones proteinuria. This association has been reported previously only in the presence of myelomatous infiltration of the gastrointestinal tract or in amyloidosis, and hence the cases reported appear to be unique.

Rats injected intraperitoneally with 1 g of bovine serum albumin (BSA) daily for 5 days develop heavy proteinuria and there is swelling and loss of the foot processes of the glomerular epithelial cells. Initially the urinary protein consists of about 55 per cent. BSA and about 40 per cent. rat serum albumin. Proteinuria persists when the injections of BSA are stopped. BSA disappears from the urine and 80-90 per cent. of the urinary protein is rat serum albumin. The persisting proteinuria is caused by glomerular damage resulting from disruption and necrosis of the glomerular epithelial cells leading to complete sclerosis of glomeruli. This damage does not appear to be immunologically determined.

Three hundred and forty-six nulliparous women with pregnancy-induced hypertension prior to term were monitored in a high-risk pregnancy unit while awaiting fetal maturity. Management included ambulation as desired, regular hospital diet without salf restriction, blood pressure measured 4 times daily, weight and urine protein determined 3 times each week, creatinine clearance determined weekly, and serial sonography to monitor fetal growth. Sedation and antihypertensive agents were not prescribed. Delivery was delayed until term unless hypertension persisted or recurred following an initial salutary response. Factors other than hypertension that contributed to the decision to effect delivery were 1) rapid weight gain, 2) decreasing creatinine clearance, 3) appearance of significant proteinuria, 4) suspected fetal growth retardation, and 5) the development of severe headache or scotomata. With this method of management the perinatal mortality rate was 9/1000. Only 5 infants developed the respiratory distress syndrome and all survived. There were 26 women who left the unit against medical advice. Severe hypertension subsequently developed in 7 of these women and 4 of their fetuses were stillborn. The perinatal mortality rate among this group of patients was 154/1000. It is concluded that the nulliparous patient with pregnancy-induced hypertension prior to term can be safely managed by hospitalization and close observation as a viable alternative to prompt delivery.

Chlorambucil, in combination with prednisone, was compared with prednisone alone in a randomized controlled trial in 21 children with either steroid-dependent or frequently relapsing nephrotic syndrome to assess its effect on the duration of remission and the rate of relapse. All control patients treated with prednisone alone continued to relapse at the same rate, with all patients experiencing a return of proteinuria by seven months. Conversely, those who received the same prednisone therapy along with chlorambucil for six to 12 weeks remained in complete remission, without further medication, during 12 to 34 months of follow-up observation. Complications were minimal. Immediate side effects commonly reported with cyclophosphamide were not seen with chlorambucil. Comparison with published reports also suggests that remission induced by chlorambucil is more stable than that after cyclophosphamide. Chlorambucil appears to be of value in the frequently relapsing nephrotic patient, adding an effect that is unattainable with prednisone alone.

Twelve cats were used to study autolytic changes in glomerular morphology and compare these with lesions of naturally occurring feline renal disease. The 12 cats had normal clinical, urinary, and blood features. One kidney (0-hour control) was excised immediately after a given cat was euthanatized, and portions of it were prepared for light and electron microscopy. The opposite kidney (autolytic) remained in situ for selected postmortem intervals, up to 24 hours, at which time it was similarly processed. Renal tissues from 4 additional cats (3 with proteinuria and 1 with diabetes mellitus) were processed and examined for comparison. Zero-hour control kidneys had the following mean quantitations: renal weight was 9.9 g; glomerular diameter, 83 mum; number of cells per glomerulus in 1-mum section was 63; and diameter of cell nuclei was 6.3 mum for mesangial, 6.7 mum for visceral epithelial, and 6.4 mum for endothelial. In comparison with 0-hour control kidneys, autolytic kidneys had increased weight and glomerular diameter, but the diameter of cell nuclei decreased. Basement membrane thickness and glomerular cell numbers did not differ between 0-hour control and autolytic kidneys. Kidneys from 4 diseased cats had increased glomerular diameter and glomerular basement membrane changes characterized by hyalin thickening and dense deposits. These changes are compatible with a lesion diagnosis of membranous glomerulonephritis.

A retrospective analysis of 235 patients at the National Institutes of Health who met at least five criteria for systemic lupus erythematosus (SLE) indicated that 45% were hypertensive. Approximately two thirds of these hypertensive patients had creatinine clearances of more than 60 ml/min and nonnephrotic range proteinuria. Only 16% of normotensive patients had creatinine clearances of less than 60 ml/m9n. A subgroup of 36 patients with SLE and with biopsy-proved diffuse renal disease were studied. For these patients, the presence of hypertension could not be correlated with the degree of proteinuria or hematuria, with the level of serum complement, or with the presence of casts, focal necrosis, crescent formation, or interstitial inflammation. Hypertensive patients had a median age of 24.5 years; the majority had creatinine clearances of more than 60 ml/min. In SLE, hypertension is not necessarily associated with advanced renal disease, and high blood pressure may occur relatively early in the course of the disease.

Serum total, percentage free fraction and absolute serum free hormone concentration of thyroxine and triiodothyronine were measured in control, pregnant and oral contraceptive users, together with the daily urinary losses of unconjugated thyroid hormones. Increased urinary losses of both hormones, in particular thyroxine, were apparent in pregnancy and these could not be explained in terms either of an increased filtered load of hormone or the presence of proteinuria. The possible existence of filterable small-molecular weight hormone-binding substances in the urine of pregnant patients is discussed. It is concluded that assay of urinary thyroid hormones during pregnancy is of limited diagnostic value because of overlap with thyrotoxic values.
