Serum trimethylamine-N-oxide and protein energy wasting: some factors that should be considered.

The MHD patients were divided into two groups by the median level: the high TMAO group (7206 ng/mL) with 85% in PEW and the low TMAO group (4080.9 ng/mL) with only 34% in PEW. Dear Sir, We have read with great interest the paper entitled 'Correlation between serum trimethylamine I N i -oxide concentration and protein energy wasting in patients on maintenance hemodialysis' by Hu et al. [[1]]. According to the former study, it showed that serum TMAO levels in HD patients reflect the net effect of TMAO production and clearance. [Extracted from the article]
