Chronic malnutrition: protein metabolism

Albumin metabolism in children with protein malnutrition.

Malnutrition and Electrolyte Metabolism

Abnormal total body and serum electrolyte concentrations are common in protein-energy malnutrition (PEM). The subject of electrolyte metabolism in PEM was studied in depth in the 1960s and early 1970s but has seldom been investigated in the past decade. Electrolyte status has been assessed by a variety of methods, including electrolyte concentrations in serum, urine, or muscle tissue; external ...

Histidine metabolism in experimental protein malnutrition in rats.

1. The activities of the enzymes histidase, urocanase and histidine-pyruvate transaminase were studied in rats under conditions of protein malnutrition. Urocanase and histidase activities in liver were markedly lowered in experimental protein malnutrition, but the activity of histidine-pyruvate transaminase was unaffected. There is a metabolic control in vivo of the enzymes involved in the cata...

Protein catabolism in chronic uremia: is it due to malnutrition?

The high prevalence of anthropometric measurements and laboratory values that are similar to those in patients with protein-energy malnutrition has lead to the classification of a large number of dialysis patients as being malnourished. However, malnutrition in the strict sense implies that abnormalities will be reversed if more food is eaten. There is virtually no evidence, however, that simpl...

Factors Associated With Protein-energy Malnutrition in Chronic Liver Disease

We aimed to elucidate the incidence of protein–energy malnutrition (PEM) in patients with chronic liver disease and to identify factors linked to the presence of PEM. A total of 432 patients with chronic liver disease were analyzed in the current analysis. We defined patients with serum albumin level of 3.5 g/dL and nonprotein respiratory quotient (npRQ) value using indirect calorimetry less th...
