Abstract: A defined peak region residing between about 3.2 and 3.4 ppm of a proton NMR spectrum of an in vitro biosample is electronically evaluated to determine a level of trimethylamine-N-oxide (“TMAO”). The biosample may be any suitable biosamples including human serum with a normal biologic range of between about 1-50 ?M or urine with a normal biologic range of between about 0-1000 ?M.

Abstract: Provided herein are compositions, systems, and methods for treating a disease, such as kidney and/or cardiovascular disease, with an agent that reduces the production of trimethylamine (TMA) or trimethylamine-n-oxide (TMAO) in a subject.

Abstract: The present invention provides markers and methods for determining whether a subject, particularly a human subject, has or is at risk of developing, a disease such as cardiovascular disease, diabetes mellitus, insulin resistance, metabolic syndrome, NAFLD (Nonalcoholic Fatty Liver Disease) or NASH (Nonalcoholic Steatohepatitis) (e.g., within the ensuing year, two years, and/or three years). The present application also relates to the use of such markers and methods for monitoring the status of such diseases in a subject or the effects of therapeutic agents on subjects with such diseases.

Abstract: Methods of characterizing a test subject's risk of having or developing cardiovascular disease are provided. The methods include using an analytic device to determine levels of choline-related trimethylamine-containing compounds such as trimethylamine N-oxide, choline, or betaine in a biological sample obtained from the subject and comparing the levels of the choline-related trimethylamine-containing compound in the subject's biological sample to a control value. The test subject's risk of having cardiovascular disease is then characterized as higher if the levels of the choline-related trimethylamine-containing compound are higher than the control value. Also provided are methods of identifying a subject at risk of experiencing a complication of atherosclerotic cardiovascular disease, and methods of evaluating the efficacy of a cardiovascular therapeutic agent in a subject with cardiovascular disease using levels of choline-related trimethylamine-containing compounds.
