The activity of inosine monophosphate dehydrogenase (IMPDH: EC 1.2.1.14) was measured in erythrocyte lysates using a non-radiolabelled method linked to reversed-phase liquid chromatography (RPLC). The mean activity in erythrocytes from healthy controls using this sensitive method was extremely low (mean 85 pmol/h per mg protein, range 4-183). The elevated erythrocyte IMPDH activity reported previously in hypoxanthine-guanine phosphoribosyltransferase (HPRT) deficiency was confirmed (mean 234 pmol/h per mg protein). Erythrocyte IMPDH activity of patients with other disorders of purine metabolism, or with leukaemias and lymphomas, showed no marked difference from controls, except in one instance--an immunodeficient child with purine nucleoside phosphorylase (PNP) deficiency, treated with Ribavirin, where a 30-fold increase in activity was found (2670 pmol/h per mg protein). Investigation of erythrocyte IMPDH in other immunodeficient children with normal PNP activity demonstrated that this grossly elevated erythrocyte activity was attributable to induction of IMPDH by Ribavirin therapy.
