Simultaneous studies of serum and urinary proteins in 294 adult proteinuric patients are presented. Our data showed that these studies can provide valuable guides for clinical diagnosis. In the group of idiopathic nephrotic syndrome, hypoalbuminemia, hypogammaglobulinemia and hyper-alpha 2 globulinemia were most marked. Urinary protein electrophoresis (PEP) showed a well-selective pattern with albumin and beta globulin as the main constituents. In the other groups of proteinuric patients the hypoalbuminemia and hyper-alpha 2 globulinemia were milder and urinary PEP generally showed non-selective pattern. In the groups of acute glomerulonephritis and lupus nephropathy, C3 was generally decreased; polyclonal gammopathy was frequently encountered and alpha 1 acid glycoprotein was markedly increased. In the cases of chronic glomerulonephritis and diabetic nephropathy and the levels of gamma globulin, C3 and alpha 2 acid glycoprotein were usually within normal limits. Urinary protein selectivity index in this series of adult patients was not a useful diagnostic parameter.

Infection has been recognized as an important cause of morbidity and mortality in children with nephrotic syndrome. However, the incidence and severity of infection and the mechanisms responsible for the increased susceptibility to infection are still unclear in adults. We studied 86 consecutive adult patients with nephrotic syndrome but no diabetic nephropathy. Risk factors for infection were evaluated by logistic regression analysis. Infections were found in 16 patients (19%), of whom six died of infection and two developed end-stage renal failure associated with infection. The relative risk for bacterial infection among patients with serum immunoglobulin G (IgG) levels below 600 mg/dL was 6.74 compared with that for patients with serum IgG levels over 600 mg/dL (95% confidence interval, 1.22 to 36.32; P = 0.029). In patients with serum creatinine levels over 2.0 mg/dL, the relative risk of bacterial infection was 5.31 compared with patients with serum creatinine levels below 2.0 mg/dL (95% confidence interval, 1.08 to 26.09; P = 0.040). Intravenous immunoglobulin (10 to 15 g) was administered prospectively every 4 weeks to 18 patients with serum IgG levels below 600 mg/dL until serum IgG levels increased to over 600 mg/dL. Administration of immunoglobulin resulted in a decreased rate of bacterial infections to a level equal to that in patients with endogenous levels over 600 mg/dL. These data indicate that hypogammaglobulinemia and renal insufficiency are independent risk factors for bacterial infection in adult patients with nephrotic syndrome. The effects of intravenous immunoglobulin suggest that maintenance of serum IgG levels over 600 mg/dL may reduce the risk of infection.
