Quantification of human plasma inorganic pyrophosphate. I. Normal values in osteoarthritis and calcium pyrophosphate dihydrate crystal deposition disease.

The methodologic variables of the UDPG pyrophosphorylase method for analysis of inorganic pyrophosphate (PPi) levels in biologic fluids are described. Use of a tourniquet in collection of blood specimens elevated plasma PPi levels from 35% to 55% above control values and may explain the differences in published normal values. The sodium pyrophosphate decahydrate used to prepare the standard solution lost 8 waters of hydration after dessication, which could result in the calculation of spuriously elevated PPi levels. Normal plasma PPi concentration was 2.18 muM with a range (95% confidence limits) of 0.58-3.78 muM. Comparison of plasma PPi in normal subjects, patients with primary osteoarthritis, and patients with calcium pyrophosphate dihydrate deposition disease revealed no significant intergroup differences.[1]
