From the AP story:

Berlusconi’s party and its allies won strong victories in both houses of parliament despite a strong final sprint by his main rival, Walter Veltroni, who ran a campaign that could have come out of Barack Obama’s playbook, with calls to “Vote for change” and supporters armed with “We can!” banners.

And here’s a more precise projection of the result — it looks like a sound victory:

In the 315-member Senate, Berlusconi was projected to control 167 seats to Veltroni’s 137. In the lower house, his conservative bloc led with 46 percent of the votes to 39 percent.
