This study investigates the effects of a late evening snack (LES), of 200 kcal of rice ball, on energy metabolism in cirrhotic patients. Impaired nutritional metabolism has been associated with cirrhosis, and frequent intake of small meals may prevent early-onset starvation, and maintain nourishment in these patients.
Twenty-one cirrhotic patients and 26 control subjects (Control) were recruited for this study. Patients were subsequently treated by LES (LC-LES) and by a non-LES regimen (LC-NLES).
Resting energy expenditure and respiratory quotient (RQ) were assessed by indirect calorimetry at 0830, 1130 and 1430. Blood glucose and non-esterified fatty acids (NEFA) were measured just before the energy metabolism measurements. The regular diet included three major meals and LES, at 0900, 1200, 1800 and 2100, respectively. The Control and LC-NLES groups received only the major meals, whereas the LC-LES group received three meals plus 200 kcal LES for 7 days. There was no difference in the total energy intake among Control, LC-NLES and LC-LES groups.
Respiratory quotient in LC-NLES was significantly lower than that of Control at 0830. Respiratory quotient value in LC-LES significantly elevated from that in LC-NLES. The RQ values did not differ among Control, LC-NLES and LC-LES at 2 h after the meal (1130 and 1430). Non-esterified fatty acids in LC-LES were lower than that in LC-NLES after overnight fasting.
The ingestion of a 200 kcal rice ball LES can improve the nutritional metabolism in cirrhotic patients.
本研究调查了200千卡饭团的晚间小吃(LES)对肝硬化患者能量代谢的影响。营养代谢受损与肝硬化有关,频繁少食多餐可预防早期饥饿,并维持这些患者的营养状况。
本研究招募了21名肝硬化患者和26名对照受试者(对照组)。患者随后接受LES治疗(LC-LES组)和非LES方案治疗(LC-NLES组)。
通过间接测热法在08:30、11:30和14:30评估静息能量消耗和呼吸商(RQ)。在能量代谢测量前测量血糖和非酯化脂肪酸(NEFA)。常规饮食包括三餐和LES,分别在09:00、12:00、18:00和21:00。对照组和LC-NLES组仅接受三餐,而LC-LES组接受三餐加200千卡LES,持续7天。对照组、LC-NLES组和LC-LES组的总能量摄入无差异。
LC-NLES组在08:30时的呼吸商显著低于对照组。LC-LES组的呼吸商值较LC-NLES组显著升高。餐后2小时(11:30和14:30),对照组、LC-NLES组和LC-LES组的RQ值无差异。过夜禁食后,LC-LES组的非酯化脂肪酸低于LC-NLES组。
摄入200千卡饭团的LES可改善肝硬化患者的营养代谢。
