Orthostatic proteinuria and milk ingestion.
An adolescent, contemplating a military career, was found to have orthostatic proteinuria. A thorough evaluation failed to reveal any renal abnormalities. He was tested on a milk-free diet at the request of the parents. The proteinuria cleared, but recurred on an initial open challenge; it did not recur subsequently on a blinded challenge. This experience suggests that patients with orthostatic proteinuria should be evaluated with an elimination diet trial.
