Sir,
Barreiro and Soriano present an interesting hypothesis for what seems to be a paradoxical depletion of CD4+ cells in the face of virological suppression when the combination of didanosine and tenofovir is used.1 The central tenet of their hypothesis is the inhibition of purine nucleoside phosphorylase (PNP) by tenofovir or its metabolites such that an accumulation of deoxyribonucleotides, particularly dGTP, leads to a specific T-lymphocytopenia. This situation is akin
