[Nutritional levels and in vitro tests of thyroid function in patients on a chronic hemodialysis program]

The nutritional status of 31 patients on regular hemodialysis (RHD) and of 32 control subjects was assessed by the Simić RTM/M classification, and in vitro thyroid function tests were determined in each subgroup. There were 13 malnourished, 13 normally nourished and 5 obese patients on RHD and 9 malnourished and 23 normally nourished control subjects. Differences between subgroups were considered in the light of their sex and age structure, duration of regular hemodialysis, proportion of patients with concomitant chronic illness, and the proportion of patients which received transfusion within the last 7 days. TT4, FT4 and rT3 were influenced by the nutritional status of the patients on RHD, while TBG, TT3 and FT3 were not. The statistical significance between RHD patient subgroups and the subgroups of control subjects was altered only in the case of TT4.
