Effect of spontaneous bacterial peritonitis on energy metabolism in male patients with alcoholic liver cirrhosis
Objective To explore the influence of spontaneous bacterial peritonitis(SBP)on the energy metabolism of male patients with alcoholic liver cirrhosis(ALC).Methods A total of 85 male ALC patients in Beijing You'an Hospital,Capital Medical University from January 2018 to June 2023 were selected,and were divided into the SBP group(n=34)and the non-SBP group(n=51)based on the presence or absence of SBP.Indirect energy metabolism was measured for all patients,and energy metabolism indicators were collected,including resting energy expenditure(REE),predicted resting energy expenditure(pREE),respiratory quotient(RQ),carbohydrate oxidation rate(CHO%),fat oxidation rate(FAT%),and protein oxidation rate(PRO%).Blood routine tests and liver function tests were conducted for all patients.The levels of ALT,AST,T-BIL,ALB,REE,pREE,REE/pREE,RQ,CHO%,FAT%,and PRO%were compared between the two groups.The REE,pREE,REE/pREE,RQ,CHO%,FAT%,and PRO%were compared among the groups without ascites,with a small amount of ascites,with a moderate amount of ascites,and with a large amount of ascites by one-way analysis of variance.Results The 85 patients with ALC ranged in age from 30 to 63 years,with an average age of(51.5±7.8)years.The levels of ALB[(30.93±5.49)g/L vs.(34.00±5.42)g/L],prealbumin[(102.13±39.60)g/L vs.(136.00±67.65)g/L],and Hb[(105.47±24.44)g/L vs.(117.76±26.17)g/L]in the SBP group were lower than those in the non-SBP group.The REE/pREE[(106.00±16.37)%vs.(95.41±13.00)%]and FAT%[(50.59±14.92)%vs.(44.20±12.13)%]in the SBP group were higher than those in the non-SBP group,while the RQ[(0.78±0.05)vs.(0.80±0.05)]was lower than that in the non-SBP group.The REE/pREE in the large amount of ascites group was higher than those in the small and moderate amount of ascites groups[(107.57±17.11)%vs.(96.46±14.98)%,(96.73±13.93)%],and the differences were statistically significant(P<0.05).Conclusions Both SBP and the amount of ascites can affect the energy metabolism of ALC patients.SBP can increase the REE/pREE and FAT%and decrease the RQ value in ALC patients.
