  The consideration of the holographic dark energy approach and matter creation
effects in a single cosmological model is carried out in this work accordingly,
we discuss some cases of interest. We test this cosmological proposal against
recent observations. Considering the best fit values obtained for the free
cosmological parameters, the model exhibits a transition from a decelerated
cosmic expansion to an accelerated one. The deceleration-acceleration
transition can not be determined consistently from the coincidence parameter
for this kind of model. At effective level the parameter state associated to
the whole energy density contribution describes a quintessence scenario in the
fluid analogy at present time.
