Hypertriglyceridemia and lipid tolerance in preterm infants with a birth weight of less than 1250 g on routine parenteral nutrition. Clin Nutr 2021; 40:4444-4448. [PMID: 33526286 DOI: 10.1016/j.clnu.2020.12.039] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/22/2020] [Revised: 10/26/2020] [Accepted: 12/29/2020] [Indexed: 11/25/2022]
Abstract
OBJECTIVES To study the association of hypertriglyceridemia and of lipid tolerance with clinical and nutritional data in preterm infants receiving routine parenteral nutrition. DESIGN We retrospectively studied 672 preterm infants (gestational age <32 weeks) with birth weight <1250 g, consecutively admitted to our NICU, born between 2004 and 2018. Selected prenatal data and interventions, parenteral intakes and diseases were considered. Hypertriglyceridemia was defined as plasma triglycerides >250 mg⋅dL-1. Lipid tolerance was defined as the ratio of plasma triglycerides to the intravenous lipid intake at the time of sampling. Variables associated to hypertriglyceridemia and to lipid tolerance were identified by multiple logistic and linear regression analyses. RESULTS Hypertriglyceridemia occurred in 200 preterm infants (30%), ranging from 67% at 23 weeks to 16% at 31 weeks' gestation. In 138 infants (69%) hypertriglyceridemia occurred at a lipid intake of 2.5 g⋅kg-1 or less. Lipid tolerance was reduced especially in infants of less than 28 weeks' gestation (14.3 ± 9.3 vs 18.8 ± 10.2, respectively, p < 0.001). Lipid tolerance was negatively associated with respiratory distress syndrome (OR = -1.14, p = 0.011), patent ductus arteriosus (OR = -1.73, p < 0.001), small for gestational age (OR = -2.96, p < 0.001), intraventricular haemorrhage (OR = -3.96, p < 0.001), late onset sepsis (OR = -8.56, p = 0.039). CONCLUSION Preterm infants on routine parenteral nutrition were able to tolerate markedly lower intravenous lipid intakes than the recommended target values of current guidelines. Lipid tolerance was associated with some of the major complication of prematurity, possibly at risk of developing hypertriglyceridemia.

Abstract
OBJECTIVE To determine the prevalence of high TG levels in extremely low birth weight (ELBW) infants and what the risk factors are for high TG levels. STUDY DESIGN We performed a prospective observational study of triglyceride concentrations in extremely low birth weight infants receiving lipid infusions. Lipid infusions were begun at 0.5 grams/kg/day at age one day and the dose advanced by 0.5 grams/kg/day. Triglyceride concentrations were drawn when the dose reached 1 and 2 grams/kg/day. We compared infants with normal triglyceride levels (≤200 mg/dl) with those with elevated triglyceride levels (>200 mg/dl) with univariate and multivariate analysis. RESULTS There were 75 infants included in the analysis. Twenty (26.7% , 95% CI = 16.6-36.7%) had triglyceride levels >200 mg/dl. On multiple logistic regression analysis, lower birth weight was associated with the risk of an elevated triglyceride level. Triglyceride levels >200 mg/dl did not predict future mortality or morbidity. CONCLUSION Elevated TG levels occur commonly in ELBW infants and are associated with a lower birth weight.

Abstract
In order to prevent fatty acid deficiency and to supply enough energy, intravenous fat emulsion is necessary for parenteral nutrition in preterm neonates. However, parenteral administration of intravenous fat emulsion can induce lipid intolerance. The purpose of this study was to analyze risk factors for lipid intolerance in very low birth weight infants. This retrospective study included 80 preterm neonates whose birth weight was less than 1,500 g. Subjects were divided into 2 categories: those with a serum triglyceride level of ≥ 200 mg/dl (n = 33, 41%) and those with a serum triglyceride level of < 200 mg/dl (n = 47, 59%). We conducted logistic regression analysis using variables which were significant in univariate analysis. All statistical analyses were processed in SPSS version 19.0. Four risk factors for lipid intolerance were obtained through analysis of the electronic medical record. Lipid intolerance occurred more frequently in neonates with sepsis; those with a birth weight less than 1,000 g; those who was administered intravenous fat emulsion more than 2.6 g/kg/day; and those whose gestational age was less than 28 weeks. It is suggested that serum triglyceride levels should be closely monitored to prevent lipid intolerance in preterm neonates with the aforementioned characteristics.

Abstract
The in vitro effect of a lipid emulsion (intralipid) on interleukin-2 (IL-2) production by cord blood mononuclear cells (CBMC) of preterm and term newborn infants was examined and compared to that of peripheral blood mononuclear cells (PBMC) of adults. Intralipid, added at concentrations accepted in clinical practice, caused a dose-dependent inhibition of IL-2 activity tested by bioassay. IL-2 levels, tested by radioimmunoassay (RIA), were found to be reduced only in supernatants derived from CBMC of term infants and not in those derived from MC of preterm infants or adults. The capacity of the IL-2 dependent cell line CTLL-2 to respond to IL-2 was abolished in the presence of intralipid, suggesting an interference with the binding of IL-2 to its receptor on these cells. It is conceivable that administration of intralipid to preterm infants may interfere with the binding of IL-2 to the specific receptors on their activated lymphocytes, with a possible subsequent suppression of their immune response.

Abstract
BACKGROUND Prolonged parenteral nutrition with lipid emulsions is essential to provide sufficient energy supply and to avoid essential fatty acid deficiency in preterm infants. However, chronic administration of lipid emulsions may lead to the development of pathological plasma lipid and LP-X concentrations. The aim of this study was to evaluate the relative importance of the phospholipid-triglyceride (PL-TG) ratio and the source of phospholipid in lipid emulsions, with respect to plasma lipid and LP-X levels. METHODS Rats were infused for 9 days with IV lipid emulsion containing 10% (IL-10) or 20% (IL-20) egg lecithin or Lipofundin containing 20% soya lecithin (LF), with PL-TG ratios of .12, .06, and 0.75, respectively. RESULTS LF significantly increased plasma triglyceride concentration (p < .01), whereas the rise in cholesterol levels observed with all emulsions was primarily caused by the increase in low-density lipoprotein cholesterol concentrations. The plasma phospholipid concentration was increased most by IL-10 (p < .005). There was a strong correlation between the PL-TG ratio of emulsions and the developing plasma phospholipid and LP-X concentrations (r2 = .91 and .96, respectively), despite the different origin of phospholipids in the emulsions, suggesting that it is the PL-TG ratio, rather than the source of phospholipids in lipid emulsions that primarily influences developing plasma lipid and LP-X concentrations. CONCLUSION These results indicate that the administration of lipid emulsions with lower PL-TG ratios should be considered, to avoid the development of pathological plasma lipoprotein concentrations.

Abstract
The ability of neonates to eliminate and utilize lipid emulsions after surgery was investigated in 12 patients. All were subjected to major surgery within 29 h of birth. All neonates were given 10% glucose iv intraoperatively. Six patients continued with 10% glucose iv for 24 h postoperatively and 6 patients received a combination of 5% glucose and soy bean emulsion (Intralipid 20%). Both regimes provided equal amounts of fluid and energy. Blood glucose, lactate, triglycerides, free fatty acids, fractions of fatty acids in triglycerides, 3-hydroxybutyrate and arterial blood gases were measured at predetermined intervals throughout this period. Administration of a lipid emulsion early after neonatal surgery was well tolerated and utilized, with some latency. Concentrations of triglycerides, free fatty acids and 3-hydroxybutyrate were higher in the lipid group, but no accumulation of these substances was found. Palmitinic and linoleic acid were also higher in the lipid group.

Abstract
Plasma lipoprotein levels and composition have been determined in preterm and small-for-gestational-age (SGA) infants, and compared to full-term infants, during the first week of life. Significantly lower levels of HDL and higher levels of VLDL were found in both preterm and SGA infants in comparison to full-term healthy infants. These results suggest a low capacity to metabolize VLDL. Preterm infants showed a behaviour similar to full-term infants with regard to the changes in lipoprotein composition. Small-for-gestational-age infants showed a higher lipoprotein lipid content than preterm infants. A low ratio of cholesteryl ester to free cholesterol (CE/FC) was found in both preterm and SGA infants suggesting a reduced lecithin: cholesterol acyl transferase (LCAT) activity. In preterm infants we observed no changes in the CE/FC ratio during the first week of life, whereas in SGA infants this ratio increased after birth.

Abstract
OBJECTIVE To investigate lipid tolerance in sick, ventilator-dependent, very low birth weight infants from the first day of life and the effects of early introduction of intravenously administered lipid (IVL) on glucose homeostasis. METHOD Twenty-nine infants in the neonatal intensive care unit with birth weight less than 1500 gm received isocaloric, isonitrogenous parenteral feedings from day 1 with either IVL, 1 gm/kg from day 1 to 3 gm/kg from day 4 (group I; n = 16), or IVL added only from day 8 (group II; n = 13). Possible adverse clinical effects were monitored. Blood metabolites, nonesterified fatty acids, serum triglycerides, and insulin levels were determined daily. Arterial blood gases were measured and changes in partial pressures of oxygen and of carbon dioxide in arterial blood were compared between the two groups. RESULTS Early lipid infusion did not appear to have deleterious effects on blood gas tensions or to increase respiratory morbidity. The incidence of other adverse clinical effects that may be associated with IVL was not increased by earlier introduction of lipid. Serum lipid values were comparable to those of preterm infants receiving IVL at a later postnatal age. Blood glucose concentrations were higher in group II (mean, 7.50 (SEM 0.43) mmol/L) than in group I (mean, 6.01 (SEM 0.28) mmol/L; p less than 0.05). There was no evidence of increased gluconeogenesis in infants in group I and no correlation between blood glucose concentrations and serum nonesterified fatty acid concentrations. CONCLUSION When given infusion rates not exceeding 0.15 gm/kg/hr, sick, very low birth weight infants can tolerate IVL with stepwise dose increases from the first day of life without an increased incidence of possible adverse effects.

Abstract
To establish nutritional management of low birth-weight infants according to their individual metabolic situation, hepatocellular partial function was studied in 13 appropriate (AGA) and 11 small-for-gestational-age (SGA) low birthweight (LBW) infants during the first weeks of postnatal life. The concentrations of total bile acids and of alpha-amino-nitrogen in serum, the renal excretion of urea and ammonia and the renal excretion of 15N after enteral administration of 3 mg 15N-labeled methacetin/kg were measured. In comparison to AGA infants, SGA infants had elevated serum concentrations of total bile acids and of alpha-amino-nitrogen, decreased excretion of urea, increased excretion of ammonia in urine, and lower urinary 15N-excretion after enteral administration of 15N-labeled methacetin. The data suggest that hepatocellular functions are influenced by intrauterine growth retardation resulting in a reduced metabolic capacity in SGA infants. The metabolic differences between SGA and AGA infants should be considered in the nutritional management of LBW infants.

Abstract
Because 10% and 20% intravenously administered lipid emulsions (intralipid preparations) differ in their phospholipid/triglyceride ratio (0.12 and 0.06, respectively), 28 low birth weight infants requiring parenteral nutrition for at least 1 week were selected at random to receive either emulsion to determine the effects on plasma lipids and lipoproteins. Triglyceride intake was progressively increased to reach 2 gm/kg per day between days 4 and 7. During that period, all plasma lipids in samples taken 6 hours after infusion were higher in the 10% intralipid group. In comparison with day 0 values, triglyceride concentrations decreased (63 +/- 7 to 45 +/- 4 mg/dl; p less than 0.05) in the 20% group. Cholesterol levels increased in both groups, but the rise was more than twofold higher in the 10% group. Phospholipid increase was approximately 25% in the 20% group but more than 125% in patients receiving the 10% emulsion (p less than 0.005). The changes in plasma cholesterol and phospholipid levels were almost entirely in low-density lipoproteins. After 7 days, eight infants from each group were given the alternate emulsion, which resulted in a reversal of lipid patterns in each patient. We conclude that the higher phospholipid intake in 10% than in 20% intralipid is associated with higher plasma triglyceride concentrations and leads to accumulation of cholesterol and phospholipids in low-density lipoproteins. Emulsions with lower phospholipid content may be preferable for low birth weight infants and perhaps other patient populations with impaired removal of parenteral fat emulsions.

Abstract
We compared the effects of Intralipid and dextrose infusion on plasma lecithin:cholesterol acyltransferase (LCAT), plasma lipid profiles and lipolytic activity. We used 5-week-old male Sprague-Dawley rats which were given total parenteral nutrition (TPN) with either Intralipid (3 g/kg body weight) or an equicaloric amount of 25% dextrose in the presence or absence of heparin (1 or 10 IU/ml of TPN). 40 min after the end of 4 h of infusion, plasma LCAT activity was significantly decreased (P less than 0.001), while total cholesterol and free fatty acid levels were significantly (P less than 0.05) increased in rats given Intralipid as compared to those given dextrose. We found associations (P less than 0.005) between LCAT activity and total cholesterol and between LCAT and free fatty acid levels; the coefficients of negative correlation were 0.543 and 0.607, respectively. Concomitantly to the increment in plasma total cholesterol levels, there was a decrease in the high-density lipoprotein (HDL) cholesterol fraction; the latter, which was 40% of the total plasma cholesterol in control and dextrose-infused rats, declined to 9% in rats given Intralipid. Administration of heparin during Intralipid infusion, even up to 10 IU/ml of TPN, did not affect any of these changes. After dextrose infusion, the values of all three parameters were similar to those of the control group. Plasma lipolytic activity was not significantly different between rats given infusion (Intralipid or dextrose) and controls. However, in the presence of heparin, plasma lipolytic activity increased similarly in both infused groups. These data indicate that in young rats, Intralipid infusion leads to an increase in plasma total cholesterol and free fatty acid levels, which correlates with a decrease in LCAT activity; the concurrent decrease in HDL cholesterol levels might account, in part, for the loss of LCAT activity. The administration of heparin results in an elevation of plasma lipolytic activity; however, it does not prevent the hypercholesterolemia, nor the decline in LCAT activity associated with Intralipid infusion.
