Whereas it is uncommon in Caucasians and Blacks, TPP does occur in individuals of Native American descent. The objective was to analyze the clinical, biochemical, and HLA characteristics of a group of Mexican mestizo patients with TPP. The sample was comprised of 14 men with TPP diagnosed since January 1990, based on one or more episodes of flaccid paralysis, accompanied by hypokalemia and occurring in the context of clinical and biochemical hyperthyroidism. Eight were available for HLA testing. Hyperthyroidism was diagnosed before the development of periodic paralysis in five of the patients, whereas in six it occurred afterward. The severity of paralysis did not correlate with the degree of either hypokalemia or hyperthyroidism. An increased frequency of HLA-DR3 was found in Graves' patients without paralysis but not in those with paralysis, as compared to the general population. TPP is more common than previously thought in Mexicans, in whom it behaves as in other Native American groups. The lack of HLA-DR3 association in Graves' patients with TPP is interesting, but at the moment has no pathophysiological implications.

Therefore, these combined nutrients may have a therapeutic potential during intestinal inflammation. This study was designed to investigate in humans the effects of a supplement composed of Gln and high-dosed antioxidant micronutrients compared to isomolar Gln only, on duodenal proteome.Experimental design: Enteral perfusion of Gln (0.8 mmol . kg−1. h−1) or supplement was performed in two groups of six healthy volunteers during 5 h before taking endoscopic duodenal biopsies. Protein expression was analyzed by 2-DE and the relevant proteins identified by MS/MS.Results: About 1500 protein spots were revealed in both supplement and Gln conditions. Comparative proteomics analysis indicated that 11 proteins were differentially and significantly (p≤0.05) expressed in response to the supplement. These proteins were essentially implicated in metabolism pathways, e.g. fatty acid binding protein-1 and 40S ribosomal protein SA expressions were downregulated while manganese superoxide dismutase and retinal dehydrogenase-1 expressions were upregulated.Conclusions and clinical relevance: This study provides new information on human duodenal proteome and its nutritional modulation, and supports further clinical investigations designed to evaluate the effects of Gln plus antioxidants during intestinal inflammation and cancer.
