Polyamine contents in current foods: a basis for polyamine reduced diet and a study of its long term observance and tolerance in prostate carcinoma patients

Amino Acids. 2007 Aug;33(2):203-12. doi: 10.1007/s00726-007-0524-1. Epub 2007 Jun 20.


Polyamine contents were assessed by mass spectrometry in 233 current foods and beverages. In order to reduce gut polyamine uptake, a polyamine reduced diet (PRD) and partial intermittent intestinal tract decontamination (PIITD) with neomycin or nifuroxazide was proposed as nutritional therapy to 33 prostate carcinoma patients, 30 of whom with hormone refractory prostate cancer (HRPC). Mean PRD observance was 22 +/- 19 (median: 16; range: 3-72) months. 10, 8 and 3 patients were respectively on PRD for more than 30, 36 and 64 months. No diet toxicity was observed. 8 patients had moderate intestinal intolerance due to PIITD which was interrupted. No significant differences in body weight, blood counts or serum protein levels were observed during the follow-up of patients under PRD. Performance status and pain scores were relatively stable during the trial with improved pain scores at 6 months. A PRD associated with intermittent PIITD is a safe and well observed nutritional regimen and long term observance is possible.
