The use of italics is determined by the publisher. A Style Guide in use will help writers/ editors/ production people determine when italics are used.

Lacking a formal style guide, a writer can use italics to set off words, phrases and so forth -- so long as the writer uses italics consistently throughout the piece.

Without endorsement, you can review the link below to the Chicago Manual of Style for generally accepted guidelines.
