Marginal zinc deficiency in older adults: responsiveness of zinc status indicators.

Abstract: Mild zinc deficiency is difficult to detect. In this study, traditional indicators such as plasma zinc and alkaline phosphatase did not change as would be expected in response to alterations in zinc intake. Likewise, erythrocyte metallothionein did not respond to altered zinc intakes as expected but this factor may reflect long-standing or more severe zinc depletion and thus requires additional study. Activity of the enzyme 5'-nucleotidase appears responsive to acute changes in zinc intake; however, more work … Show more

“…Most of these studies have been performed among hospitalized or institutionalized elderly or focussed mainly on the relationship between zinc status and immune function (Pepersack et al, 2001;Mitchell et al, 2003;Chandra, 2004), while data in elderly free living people are scarce. Results are heterogeneous and conflicting but in agreement with the importance of zinc supplementation in case of deficiency or in case of altered metabolism associated with reduced immune response (Turnlund et al, 1986;Cousin, 1989;McClain and Stuart, 1990;Bales et al, 1994;Sturniolo et al, 1994;Fortes et al, 1998;Brown et al, 2001;Pepersack et al, 2001;Mitchell et al, 2003;Chandra, 2004).…”

“…Otras circunstancias asociadas a la deficiencia de zinc incluyen carencia en la dieta, dieta rica en fitatos y calcio, vegetarianismo, anorexia, ausencia de depósitos de zinc en prematuros, cirrosis hepática, alcoholismo donde su consumo crónico disminuye la absorción intestinal de zinc y aumenta su excreción urinaria, por otro lado, se agrega la baja ingesta de alimentos en estos pacientes; síndromes de malabsorción intestinal, cirugía gástrica, enteropatía inducida por fárma-cos, insuficiencia pancreática, anemia perniciosa, grandes quemados, síndrome nefrótico, VIH y fibrosis quística 9,11 .…”
