MANZANO ANGUA, Juan Manuel  e  NIETO GRANADOS, María Dolores. Influence of the new Helixone^® membrane in the nutritional assessment of nursing. Rev Soc Esp Enferm Nefrol [online]. 2005, vol.8, n.4, pp.6-11. ISSN 1139-1375.

Recently a new syndrome has been described, MIA (malnutrition, inflammation and atherosclerosis), where the etiology of malnutrition and inflammation is multifactorial, and in which the accumulation of uremic toxins with a high molecular weight may have a negative influence. Main aim: to describe and compare the nutritional state of patients when they use low flux polysulphone® compared to new high flux helixone®. The study sample was made up of 25 patients. The following were recorded: anthropometrical, biochemical and inflammatory nutritional markers, other clinical parameters and other data. The nutritional results of patients when they used polysulphone® in 2001 were compared with the results obtained in the same patients in 2003, when they used helixone® for at least 12 months. The results show: a) The body mass index and brachial circumference fell minimally, and the subscapular skinfold decreased significantly (p=0.000), although without statistical validity; b) Albumin (p=0.000) and pre-albumin (p=0.031) increased significantly and c) C reactive protein increased very discreetly and ß2-microglobulin fell very significantly (p=0.009). Throughout the time our study lasted, the new helixone® membrane has not shown an improvement in the anthropometrical nutritional state, compared to polysulphone®, while it does appear to have a positive influence on the biochemical proteic nutritional state, possibly because of the improvement in the uremic state by increasing the elimination of toxins with a high and medium molecular weight.
