title: Dietary effects in the early recovery phase of kwashiorkor. Plasma levels of triglycerides, FFA, D-beta-hydroxybutyrate, glycerol, postheparin lipoprotein lipase (LPL), glucose and insulin.
abstract: The fatty liver often found in untreated kwashiorkor has been associated with highly variable concentration of circulating lipids. The effect on lipid metabolism of two isocaloric diets--one synthetic monomolecular (Vivonex) and one standard (Casilan)--which both initiated satisfactory clinical improvement was studied in 21 Ethiopian children with kwashiorkor during the first weeks of rehabilitation. Before treatment mean fasting values of all biochemical parameters were within normal ranges except for moderately elevated triglycerides--an unexpected finding-and low insulin. Individual values varied greatly; triglyceride between 0.39 and 3.49 mmol/1. FFA correlated both to glycerol, D-beta-hydroxybutyrate and triglyceride values. During treatment insulin, glucose and glycerol remained essentially unchanged and were similar in both dietary groups. In the Vivonex group only there was an initial marked, parallel fall of FFA and D-beta-hydroxybutyrate suggesting greater availability of carbohydrate and enhanced glucose utilization. This pattern of response seemed to occur without comparable inhibition of lipolysis. Triglycerides--like serum albumin--increased faster in the Casilan group. The highest mean triglyceride value was reached by day 8 in the Casilan group and by day 15 in the Vivonex group. Ten minutes following heparin injection triglycerides declined, FFA and glycerol increased indicating release of in vivo active lipase. LPL activity assayed in vitro was similar and unaffected by 2 weeks of dietary treatment in both groups. LPL activity was inversely correlated to triglycerides providing--beside the type of diet--another possible explanation for the wide variations seen in circulatory triglycerides.
