Hyperuricaemia and gout are closely related, but hyperuricaemia is an independent risk factor for endothelial damage, autoinflammation and haemodynamic abnormalities. Milk, generally known as a purine-free diet, is an essential protein source for patients suffering from hyperuricaemia and gout. As milk still contains different purine ribonucleotides, the new product, depurinized milk, almost free of purine nucleotides and uric acid, was produced. The potential effect of depurinized milk diet on serum uric acid (SUA) level, lipid parameters and blood haematological parameters was explored in rats after 72 h and 15 days, in relation to standard laboratory chow or the untreated milk diet. The beneficial effect on SUA was achieved when depurinized milk draught was given instead of standard chow for 72 h [28.39 +/- 4.76 mu m; p %26lt; 0.001 vs. standard diet (STD) 47.6 +/- 6.12, vs. untreated milk diet 31.55 +/- 8.50; p %26lt; 0.05] or as a supplement for STD for 15 days experiment (35.38 +/- 6.40 mu m; p %26lt; 0.05 vs. STD only 48.05 +/- 4.32; vs. untreated milk + STD 46.02 +/- 9.48). Depurinized milk diet significantly decreased the low density lipoproteins/high density lipoproteins (LDL/HDL) ratio (p %26lt; 0.001), triglycerides (p %26lt; 0.05) and leucocyte count (p %26lt; 0.001), while both milk draughts enhanced haemoglobin concentration (p %26lt; 0.01). In conclusion, considering the detrimental effect of persisting hyperuricaemia, the depurinized milk draught may meet the demand of healthy dairy product for population under hyperuricaemic risk.
