Urinary pseudouridine excretion in myelomatosis.
Urinary psi excretion is independent of the main indices of tumour activity in myelomatosis (serum paraprotein, serum beta 2-microglobulin, serum creatinine and urinary light chain production). The mean (+/- s.d.) psi at presentation was 40.7 +/- 22.6 nmol. mumol ucr-1, compared to 25.4 +/- 4.8 nmol. mumol ucr-1 in controls. Urinary psi levels at presentation are significantly related to prognosis, the higher the level the poorer the prognosis. However, when these levels have been stratified according to the corresponding level of serum beta 2m, the level adds little as a prognostic factor.
