Latin abbreviations, such as e.g. and i.e., are usually restricted to parenthetical text and set in Roman type, not italics, except for sic, which is italicized for visibility’s sake. Pace, Latin for “contrary to,” is italicized to avoid confusion with “pace.”
Personal initials have periods and are spaced.
