Shunt-associated glomerulonephritis

Six patients with glomerulonephritis in association with a ventriculovascular shunt were treated with three basic modes of therapy. Direct intraventricular instillation of antibiotic was used on seven occasions in five patients either as the definitive mode of therapy or as an adjunct to shunt removal. Ventricular fluid antibiotic concentrations were monitored in two patients and demonstrate that effective levels as compared to the specific minimal inhibitory concentration can only be achieved by this method. With resolution of the shunt infection, improvement in the clinical and laboratory parameters of renal function was noted. A recommended treatment protocol is outlined, including specific dosages for intraventricular antibiotics. The need for detailed and frequent post-treatment examination including serum immunoglobulin profile is stressed.
