Changes in fat distribution in children following severe burn injury.

ABSTRACT: Children with severe cutaneous burn injury show persistent metabolic abnormalities, including inflammation and insulin resistance. Such abnormalities could potentially increase their future risk for developing type 2 diabetes mellitus (T2DM) and cardiovascular disease (CVD). This could be related to changes in body composition and fat distribution.We studied body composition, fat distribution, and inflammatory cytokines changes in children with severe burn injury up to 6 months from discharge. Sixty-two boys and 35 girls (burn ?30% of total body surface area) were included.We found a decrease in total body fat and subcutaneous peripheral fat at 6 months (6% and 2%, respectively; P<0.05 each). An inverse correlation between the decrease in peripheral fat content at 6 months and the extent of burn injury (r=-041, P=0.02) was also observed. In addition, there was a 12% increase in serum tumor necrosis factor-? (TNF-?) (P=0.01 vs. discharge) and 9% decrease in serum interleukin-10 (IL-10) (P<0.0001 vs. discharge) over 6 months after burn.Severe burn injury in children is associated with changes in body fat content and distribution up to 6 months from hospital discharge. These changes, accompanied by persisting systemic inflammation, could possibly mediate the observed persistence of insulin resistance, predisposing burn patients to the development of T2DM and CVD.

Project description:BackgroundNon-severe paediatric burns can result in poor long-term health outcomes. This occurs even in cases with good acute burn-related outcomes, including minimal scarring. The mechanisms that underpin the transition from non-severe burn to sustained negative long-term health impacts are currently unknown. However, sustained metabolic and immune changes have been observed in paediatric burn studies, suggesting these changes may be important.The plasma lipidome consists of a rich pool of bioactive metabolites that play critical roles in systemic processes including molecular signalling and inflammation. We hypothesised that changes in the plasma lipidome may reflect underlying changes in health status and be linked to long-term health after burn trauma.MethodsThis study analysed the lipidome in children who had previously experienced a non-severe burn, compared to non-injured controls. Thirty-three participants were recruited between the ages of 5 and 8 years who had experienced a non-severe burn between the ages of 1 and 3 years. Plasma samples were also collected from a non-injured, healthy, age and gender matched control group (n = 21). Plasma lipids were measured using reversed-phase liquid chromatographymass spectrometery (LC-MS).ResultsIn total 838 reproducible lipid species from 19 sub-classes passed quality control procedures and progressed to statistical analysis. Analysis of individual lipid metabolites showed significantly higher concentrations of lysophosphatidylethanolamines and phosphatidylethanolamines, and significantly lower concentrations in myristic, palmitic and palmitoleic acids in the plasma of those who had experienced burn injury compared to controls.ConclusionLong-term changes in the lipid profile may give insight into the mechanisms underlying poor long-term health subsequent to non-severe burn injury. Further work to investigate the relationship between long-term pathology and lipidomic changes may lead to a better understanding of the causes of secondary morbidity post-burn and to clinical intervention to reduce the long-term health burden of burn trauma.
