  I review the properties of three X-ray accreting millisecond pulsars observed
with INTEGRAL. Out of seven recently discovered accretion-powered pulsars (one
discovered by INTEGRAL), three were observed with the INTEGRAL satellite up to
300 keV. Detailed timing and spectral results will be presented, including data
obtained during the most recent outburst of the pulsar HETE J1900.1-2455.
Accreting X-ray millisecond pulsars are key systems to understand the spin and
accretion history of neutron stars. They are also a good laboratory in which to
study the source spectra, pulse profile, and phase shift between X-ray pulses
in different energy ranges which give additional information of the X-ray
production processes and emission environment.
