Factitious proteinuria in a young girl.
A 16-year-old girl showed waxing and waning proteinuria and fat globules in urine for three years. There were no other abnormal findings except for the urinalysis. The renal biopsy findings did not indicate glomerular disease. Electrophoresis of the urinary protein showed two abnormal fractions at the alpha and beta globulins. Immunoelectrophoresis demonstrated that these abnormal proteins were not derived from human serum proteins, but were egg proteins. It appears that the proteinuria was factitious and that egg proteins were injected into the bladder, as they were also present in the bladder urine.
