In general, it's not a construction which always works very well in the passive voice. If you want to try giving us a few sample sentences with "sth" (which you should really write in full as "something", by the way ) replaced by actual words, we should hopefully be able to give you a bit more help.
I understand your sentence, but it sounds pretty strange to me. I'd use this version if I were trying to express that idea: The literature surveys keep me informed about recent research trends. Or: The literature surveys keep me up to date with recent research trends.
If you want to use "keep me abreast," the usual preposition is "of:" "Reading Computerworld keeps me abreast of developments in computing."
I agree with DonnyB about abbreviations such as "sth." Some dictionaries, especially those published in China, use them to save space. Native speakers never use them, even in text messages and Internet chat rooms.
