[Pernicious anemia with indicanuria].
A 67-year-old female was diagnosed as having classical pernicious anemia. Laboratory data included low serum vitamin B12 concentrations, abnormal deoxyuridine suppression test, methylmalonic aciduria, atrophic gastritis, positive anti-intrinsic factor antibody and Schilling test results typical of pernicious anemia. During hospitalization it was incidentally noted that her urine was green colored. Jaffe' reaction and Obermayer reaction for indicanuria were both positive. Dark purple crystalline material was obtained by centrifugation of her urine. The crystalline substance was soluble in methanol and its absorbance curve was identical to that of authentic indoxylsulphate potassium salt. Daily output of this substance was nearly 50 times normal. There was no increase in urinary excretion of monoamino-monocarboxyl amino acides. The exact reason for her indicanuria was not clear, although abnormal bacterial growth in the intestine remained as a possibility.
