The typical patient with diabetes mellitus seen at major hospitals in Papua New Guinea between 1974 and 1977 had florid symptoms, a very high blood glucose, was non-obese and non-ketotic and, frequently had neuropathy and proteinuria. In 25% hypertension was present which was significantly more common in the presence of proteinuria. Diagnosis was often delayed by failure to test urine for glucose and treatment was usually ineffective so that coma, usually non-ketotic, severe infections and gangrene occurred frequently. Although not as common as in other South Pacific countries, diabetes is increasing in Papua New Guinea. The provision of simple adequate facilities to test urine for glucose in all hospitals and the establishment of diabetic out-patient clinics in major centres to instruct both patients and other health workers are essential to improve treatment and reduce mortality and morbidity.

Forty consecutive patients whose biopsies showed focal and segmental sclerosis were studied for 6 to 16 years to establish the long-term prognosis of this group of patients. By the end of a decade 21 were dead, on regular dialysis or transplanted; only one death was unrelated to renal failure. A further 8 patients had a GFR of less than 60 ml/min/1.73 m2. Only 11 patients had normal renal function, and of these eleven only four had no urinary abnormality. Actuarially calculated survival was 75% at 5 years, 50% at 10 years, and 38% at 15 years. There was no difference between the 28 adults and the 12 children in terms of evolution. Patients with a nephrotic syndrome at presentation had a poorer prognosis than those never nephrotic. Twenty nephrotic patients were treated with prednisone, and 14 of these with cyclophosphamide in addition. One patient responded with loss of proteinuria within two months to both drugs, and another lost proteinuria when treated with cyclophosphamide. Thirteen patients received allografted kidneys; a nephrotic syndrome recurred in three patients, with histological evidence of recurrent disease in two.

Seventy-two adults with the nephrotic syndrome without renal insufficiency had a membranous type of renal histology on biopsy. These patients were randomly allocated to at least eight weeks of alternate-day treatment with prednisone or placebo in a multicenter study. Deterioration of glomerular filtration rate was significantly more rapid in placebo-treated than in prednisone-treated patients, and ultimately 10 of 38 given placebo but only one of 34 given prednisone were in renal failure (creatinine more than 5 mg per deciliter [440 mumol per liter]) or dead (P less than 0.02). In male patients and in those with nonselective initial proteinuria, there was a trend (not reaching statistical significance) toward more rapid deterioration of renal function. Age, admission blood pressure, serum creatinine, daily total protein excretion, and severity of histologic changes did not predict the subsequent course. We conclude that a short course of alternate-day prednisone therapy was beneficial in our group of patients with idiopathic membranous nephropathy.

Three patients developed proteinuria following gold therapy for rheumatoid arthritis. The clinical syndrome was a self-limiting proteinuria with normal renal function. By light and electron microscopic appearances the renal lesion was an epimembranous deposit form of membranous glomerulopathy. Immunofluorescent study showed granular deposits of IgG and C3 complement along glomerular basement membranes. By X-ray fluorescent spectroscopic examination, gold was seen to be present within the proximal convoluted tubular cells but was not identified in the glomerular subepithelial deposits. These findings are consistent with an immune-complex form of glomerulopathy in which gold is neither the antigen nor a hapten in the glomerular deposits, and they suggest the hypothesis that antibodies to tubular epithelial antigens induced by gold therapy may be a causative factor in the renal disease associated with gold therapy in rheumatoid arthritis.

Two serologically active urinary glycoproteins (HLA-A 9 and HLA-B 12) were isolated from urine provided by a patient suffering from tubular proteinuria. Their N-terminal sequences were automatically determined. The latter were identical with the sequence of another urinary glycoprotein (protein HC). The relationship between protein HC and the serological activity is discussed.

The uptake of 45Ca was measured in slices of kidney cortex from normal rats, streptozotocin-diabetic rats, and streptozotocin-diabetic rats treated early and late with insulin. Insulin therapy was performed such that blood glucose levels were controlled in half the treated diabetic animals but not in the others. Considerably earlier than evidence of nephropathy (i.e., proteinuria and increased BUN levels) in streptozotocin-diabetic rats, there was a significant decrease in active uptake of calcium by the kidney. Insulin therapy, begun immediately upon diagnosis of diabetes, maintained normal calcium transport even when blood glucose levels were not controlled. On the other hand, insulin therapy, begun 1 mo after diabetes was confirmed but before evidence of nephropathy, did not restore calcium transport to normal whether or not blood glucose was controlled. We conclude that this biochemical mechanism, which possibly may be implicated in the pathophysiology of diabetic nephropathy, is clearly influenced by duration of insulin deficiency and not by the degree in hyperglycemia.

In this case of renal vein thrombosis secondary to a nephrotic syndrome, we postulate renal disease resulted from gold therapy. We know of no previous report relating gold toxicity and renal vein thrombosis. It should be emphasized that with increasing use of gold, proteinuria and nephrotic syndrome may be more common than once suspected and, when present, predispose to the development of renal vein thrombosis.

Peroxidase labeled concanavalin A (Con A) permits the detection of some saccharide determinants. This histochemical technique permits the visualization of cellular pathological modifications not observed with other methods. Its use in an ultrastructural study of nephritis induced by a single injection of aminonucleoside demonstrated the following in podocytes. The Con A positive endoplasmic reticulum (ER), essentially the rough ER, lost its normal linear and network appearance to take on a dot dash pattern. ER contents but not attached ribosomes and membranes were Con A positive. The dot dash pattern, due to a fragmentation of the ER, appeared prior to the onset of proteinuria and was attenuated before the disappearance of proteinuria. These changes of the ER were not observed in other proteinuric states. This suggests that aminonucleoside can damage the synthesis apparatus of podocytes, revealed by the Con A method.

In seven patients on maintenance hemodialysis, de novo recurrent renal stone formation was observed. In all patients, the underlying disease was glomerulonephritis, with or without the nephrotic syndrome. All patients had considerable persistent proteinuria. The stones consisted predominantly of protein, as revealed by amino acid analysis, and had a negligible carbohydrate and lipid content. Only in some specimens, X-ray diffraction and scanning electron microscopy revealed the presence of small amounts of whewellit (calcium oxalate monohydrate) and/or uric acid. In semithin sections, the stones had a laminated texture and exhibited structural anisotropy under polarized light. With transmission electron microscopy, they were found to consist of peculair microfibrils. The proteinaceous material differed from fibrin or Tamm-Horsfall-protein, as indicated by ultrastructure, carbohydrate analysis, and amino acid analysis. Symptomatic de novo matrix stone formation constitutes another complication of dialyzed patients which has not been reported so far.

A patient with a single functioning kidney presented with the nephrotic syndrome. On the basis of highly selective proteinuria, a diagnosis was made of lipoid nephrosis. Steroid therapy over a 2-year period did not control the disease. The patient eventually developed end-stage renal failure and malignant hypertension. Nephrectomy was performed to control the hypertension. Histological examination showed congenital dysplasia in one kidney and sclerosing glomerulonephritis, malignant nephrosclerosis, as well as dysplastic changes in the other.
