Two young women developed the nephrotic syndrome within 2 weeks of presenting with diabetes and starting insulin. One had a renal biopsy which showed changes consistent with 'minimal change nephrotic syndrome' on electron microscopy but no evidence of diabetic glomerulosclerosis. Neither patient received steroids; in one the oedema resolved spontaneously but the other required diuretics. This patient also had severe IgA-deficiency probably associated with epilepsy and/or phenytoin therapy and unrelated to the pathogenesis of the nephrotic syndrome. The nephrotic syndrome may rarely present coincidentally with, or soon after, insulin-dependent diabetes mellitus (IDDM). It must be distinguished from 'insulin oedema' and classical diabetic nephropathy which occurs later in the course of IDDM. All reported cases have either remitted spontaneously or responded to steroids.

In four adults with idiopathic nephrotic syndrome and azotemia, percutaneous renal biopsy showed diabetic glomerulosclerosis, yet none had oral glucose tolerance tests diagnostic of diabetes mellitus or funduscopic evidence of diabetic retinopathy. Possible concomitant glomerular disease that may have produced proteinuria was excluded. Well documented cases of diabetic glomerulosclerosis without concurrent glucose intolerance are uncommon, and almost 30% of such patients have a past history of diabetes. Despite the absence of overt diabetes at onset of diabetic glomerulosclerosis, these patients warrant careful monitoring of plasma glucose levels and strict control of systemic hypertension.

In a pilot study 23 children with nephrotic syndrome were treated with cyclosporin A (Cs) for 6-45 months. 8 children suffered from steroid dependent minimal change nephrotic syndrome (MCNS) and had experienced at least one course with cytotoxic drugs, but had relapsed thereafter. 2 children had diabetes mellitus type I with nephrotic syndrome and 13 children had steroid resistant focal segmental glomerulosclerosis (FSGS). Cs was started with 100 mg/m2/day in two doses and increased stepwise to obtain a Cs whole blood trough level of 200-400 ng/ml. In steroid dependent MCNS treatment with Cs reduced relapse rate significantly, and prednisone therapy could be stopped completely. After discontinuation of Cs, relapses reoccurred as frequently as before. Renal function remained unimpaired despite repeated Cs treatment courses up to 38 months. In cases of nephrotic syndrome with diabetes type I Cs treatment led to complete remission without changing the insulin requirement. However, after discontinuation of Cs relapses reoccurred. In steroid resistant FSGS 6 children benefited from Cs treatment: 4 went into complete remission, 2 into partial remission. The 2 children with complete remission relapsed but remained Cs responsive. The remaining 7 children with FSGS did not respond to Cs but continued the course of their disease, with two patients rapidly progressing to terminal renal failure. Side-effects of Cs treatment were mild. It is concluded that Cs is an effective agent in steroid dependent MCNS and can be used as an alternative drug in specific cases like steroid toxicity or diabetes mellitus. In steroid resistant FSGS a trial with Cs seems to be warranted since some cases do respond favorably. To avoid nephrotoxicity treatment with Cs should always be monitored closely by determination of blood levels and renal function.

From August 1974 to January 1985, 53 patients (26 men; seven Maoris) mean age 45 (SD 15) years, with diabetes mellitus for a mean of 12 (SD nine) years had a renal biopsy and were followed. Indications for biopsy were nephrotic syndrome, proteinuria, renal impairment (five) and hematuria (one). Mean plasma creatinine concentration was 0.22 (SD 0.18) mmol/L and protein excretion 3.4 (SD 2.5) g/24 h. Diabetic nephropathy was demonstrated in 39 patients and significantly associated with retinopathy and insulin dependent diabetes mellitus (IDDM). Of the 39 patients followed for 25.7 (SD 22.8) months, 18 had died (nine myocardial infarction, six uremia, two sepsis, one stroke) and nine had begun dialysis. The five-year cumulative renal survival was 28%. The presence of the nephrotic syndrome and the plasma creatinine concentration at presentation were the best predictors of survival. Diabetics with IDDM of 20 years duration, retinopathy and heavy proteinuria, who survive the other complications of their disease, are likely to have diabetic nephropathy requiring renal replacement therapy.

Since the metabolic changes in normal pregnancy are diabetogenic, pregnancy imposes a severe stress on the metabolic milieu of diabetic patients. Moreover, many patients with long-standing diabetes have vascular complications, including retinopathy, renal insufficiency, nephrotic syndrome and hypertension, that represent separate risk factors for optimal fetal development. Recent experience has suggested that maternal hyperglycaemia, and associated fetal hyperinsulinaemia, may represent an important factor in the development of fetal complications. During the past two to three decades the incidence of perinatal deaths has been reduced in all cases of diabetics to a level that approaches the rate in healthy gravidas when severe congenital anomalies are excluded. Fetal and neonatal morbidity have also been reduced, although rates of congenital anomalies, polyhydramnios and respiratory distress syndrome remain high. In patients with significant vascular complications, especially nephropathy and retinopathy, there is no evidence that pregnancy alters the natural course of these complications. Although the morbidity associated with oedema formation and hypertension is elevated, with meticulous management of patients with diabetic nephropathy, especially in the absence of severe renal insufficiency and/or severe hypertension, pregnancy performance and outcome can be similar to other insulin-dependent diabetics.

In recent years, the prognosis for a successful pregnancy has greatly improved for women with insulin-dependent diabetes mellitus (IDDM) who are under good glycemic control and free of complications such as vascular disease and nephropathy. We report the rapid development of severe nephrotic syndrome, malignant hypertension, and microangiopathic hemolytic anemia during the first trimester of pregnancy in a 29-yr-old woman with IDDM of 18 yr duration. Our patient had no pregestational history of retinopathy or hypertension and only minimal proteinuria. Significant improvement in blood glucose levels had been achieved over the 6 mo before conception. Kidney biopsy performed before the termination of pregnancy at 10 wk gestation revealed diabetic nephropathy. No other etiology for her renal disease could be found. An arteriole was noted to have entrapped red blood cell fragments and platelet thrombi, revealing the probable source of her hemolytic process. By 8 wk postpartum, her nephrotic syndrome and hemolysis had completely resolved. At 3 mo postgestation, the patient's hypertension was still present but less severe. Her serum creatinine has continued to decrease toward normal. This is the first report of a woman with IDDM in White's classification C who developed a toxemia-like syndrome during the first trimester of pregnancy, attributable to the underlying diabetic state.

A study of 31 continuing pregnancies complicated by diabetic nephropathy was conducted to determine the effects of diabetes-associated renal disease on maternal health and fetal outcome. Throughout pregnancy there was a significant increase in maternal blood pressure (p less than 0.001) and proteinuria (p less than 0.0001), with nephrotic syndrome (greater than 3.0 gm protein/day) developing in 71% of pregnancies. After birth, however, proteinuria reverted to levels not significantly different from values in early pregnancy. There was no apparent adverse effect of pregnancy on the natural course of the underlying renal disease. Stillbirths occurred in two patients (6%), and the remaining 29 pregnancies resulted in live-births at a mean gestational age of 36 weeks. Seventy percent of these infants were appropriate for gestational age, whereas 16% were small and 13% were large for gestational age. Birth weight was best correlated with gestational age and creatinine clearance (p less than 0.0001). Neonatal complications included respiratory distress syndrome (19%), hyperbilirubinemia (26), and congenital malformations (10%). The uncorrected perinatal survival rate was 94%. These data suggest that with contemporary methods of maternal evaluation and treatment, fetal surveillance, and neonatal care, the risks to patients with diabetic nephropathy during pregnancy are not excessive. The likelihood of a successful fetal and neonatal outcome is comparable to that in other patients with insulin-dependent diabetes.

Differential macromolecule clearances were used to elucidate the mechanism of proteinuria in patients with diabetic glomerulopathy. Uncharged dextrans of graded size, combined with albumin and IgG separated into narrow fractions of varying charge by preparative electrofocusing, were used to probe the filtration barrier. Analysis of the fractional clearance profile of dextrans in the 30- to 60-A interval revealed a small fraction of filtrate volume (0.0023-0.0097) permeating large nonrestrictive glomerular pores and correlating strongly with the fractional clearances of albumin (r = .88, P less than .001) or IgG (r = .91, P less than .001). The fractional clearance of the most anionic species of albumin [isoelectric point (pI) 4.0-4.5] significantly exceeded that of less anionic species (pI 4.5-5.5) at all levels of proteinuria. A corresponding increase in fractional clearance of anionic (pI 4.5-5.0) over neutral (pI 7.0-7.5) IgG species was observed in patients with subnephrotic-range proteinuria. We conclude that a loss of barrier size selectivity underlies proteinuria in diabetic glomerulopathy. In addition, either facilitated filtration of polyanions or preferential tubular reabsorption of polycations can be invoked to explain the final composition of urinary protein. Similar loss of size selectivity combined with enhanced fractional clearance of anionic IgG in a group of nondiabetic patients with nephrotic syndrome indicates that the foregoing abnormality of renal protein handling is not unique to diabetic glomerulopathy.

Renal histopathology in 87 patients, aged over 60, with nephrotic syndrome were studied. In 57 patients diagnosed as primary glomerular disease, membranous glomerulonephritis (MGN) was of the most common histologic type (52.6% of the cases), and mesangial proliferative glomerulonephritis (21.1%), membranoproliferative glomerulonephritis (12.3%) and minimal change (12.3%) were the other types of primary glomerular disease. In the remaining 30 patients, nephrotic syndrome resulted from secondary glomerular diseases including diabetic nephropathy and renal amyloidosis. In comparison with the nephrotic syndrome of younger age group (669 cases, younger than 60 years of age), the incidence of MGN, diabetes and amyloidosis were significantly higher in the elderly. In contrast with unfavorable prognosis of diabetic nephropathy and amyloidosis, most cases of MGN and minimal change recovered from the nephrotic state with steroid treatment even in the elderly. Thus, a statistical finding that the prognosis of senile nephrotic syndrome is unfavorable as a whole, appears to be ascribable to the increased incidence of secondary glomerular diseases rather than to "aging" itself. The present results that the incidence of diabetic nephropathy was high and the outcome of MGN was favorable in the elderly, taken together with the results from other studies in Japan, are fairly different from the results of similar studies in the Western world.

A women presented at the age of 22 with anemia, hepatosplenomegaly, polyclonal hypergammaglobulinemia and a mediastinal shadow. At thoracotomy she had enlarged mediastinal lymph nodes which displayed histological features typical of angiofollicular hyperplasia. Marrow plasmacytosis was present. She developed diabetes mellitus at the age of 29 yrs after she had received oral steroid treatment for one year. The nephrotic syndrome supervened another year later. Her kidneys were enlarged before the onset of diabetes. The glomerular changes included a marked increase of mesangial matrix and segmental hypercellularity. The association of the nephrotic syndrome and angiofollicular lymph node hyperplasia is extremely rare and their interrelation remains enigmatic.
