ABSTRACT
Objective@#To explore the application value of early postoperative enteral eco-immune nutrition in the nutritional support treatment for intra-abdominal infection.@*Methods@#The prospective study was conducted. The clinicopathological data of 62 patients with intra-abdominal infection who were admitted to the 940 Hospital of the People′s Liberation Army Joint Service Support Force from February 2018 to December 2018 were collected. All patients were randomly divided into two groups by the envelope method with double-blind technique, including patients who began being given enteral eco-immune nutrition preparation at postoperative 24-48 hours in eco-immune group and patients who began being given simple enteral nutrition preparation at 24-48 hours in control group. Observation indicators: (1) analysis of immune function indices before treatment and after 7 days of treatment in the two groups; (2) postoperative conditions in the two groups; (3) follow-up. Follow-up using telephone interview was performed to detect complications and recurrence of infection up to May 2019. Measurement data with normal distribution were represented as Mean±SD, and intra-group comparison and comparison between groups were analyzed using the t test. Count data were represented as absolute numbers or percentages, and comparison between groups was analyzed using the chi-square test.@*Results@#Sixty-two patients were screened for eligibility, including 38 males and 24 females, aged (54±14)years, with the range of 22-81 years. There were 30 in the eco-immune group and 32 in the control group. (1) Analysis of immune function indices before treatment and after 7 days of treatment in the two groups: before treatment, the percentages of CD3+, CD4+, CD8+, ratio of CD4+ /CD8+, count of natural killer (NK) cells, levels of blood endotoxin and immunoglobulin A (IgA) for the eco-immune group were 61%±12%, 34%±5%, 28%±5%, 1.25±0.34, 17.26%±2.74%, (2.4±0.3)ng/L, and (1.7±0.5)g/L, versus 59%±11%, 33%±5%, 27%±4%, 1.27±0.36, 16.96%±2.99%, (2.5±0.5)ng/L, (1.8±0.5)g/L for the control group, respectively, there were no significant differences between the two groups (t=-0.563, -0.354, -0.987, 0.327, -0.462, 0.887, 0.991, P>0.05). After 7 days of treatment, the above indices for the eco-immune group were 62%±8%, 37%±6%, 27%±8%, 1.45±0.32, 22.63%±7.25%, (2.2±0.4)ng/L, and (2.3±0.4)g/L, versus 58%±8%, 32%±4%, 27%±6%, 1.26±0.22, 16.26%±2.10%, (2.7±0.6)ng/L, and (2.0±0.4)g/L for the control group, respectively, there were significant differences in the percentages of CD3+, CD4+, ratio of CD4+ /CD8+, count of NK cells, levels of blood endotoxin and IgA (t=-2.393, -4.336, -3.074, -5.338, 4.010, -3.155, P<0.05), but no significant difference in the percentage of CD8+ between the two groups (t=0.077, P>0.05). In the eco-immune group, the percentage of CD4+, ratio of CD4+ /CD8+, count of NK cells, levels of blood endotoxin and IgA showed significant differences after 7 days of treatment (t=-2.899, -2.739, -4.385, 2.157, -5.788, P<0.05), but the percentages of CD3+ and CD8+ showed no significant differences after 7 days of treatment (t=-0.490, 1.193, P>0.05). In the control group, the percentage of CD8+ and level of IgA showed significant differences after 7 days of treatment (t=3.659, -2.258, P<0.05), but the percentage of CD4+, ratio of CD4+ /CD8+, count of NK cells, and level of blood endotoxin showed no significant differences after 7 days of treatment (t=0.157, 0.759, 1.132, 1.212, -0.532, P>0.05). (2) Postoperative conditions in the two groups: the time to first flatus and duration of postoperative hospital stay of the eco-immune group were (2.4±0.5)days and (8±4)days, respectively, versus (2.9±0.7)days and (11±7)days of the control group; there were significant differences in the above indices between the two groups (t=-3.017, -2.764, P<0.05). In the eco-immune group, the incidence of complication was 6.7%(2/30), including 1 case of wound infection, 1 case of pulmonary infection. In the control group, the incidence of complication was 31.2%(10/32), including 6 cases of wound infection, 2 cases of pulmonary infection, 1 case of intra-abdominal infection, and 1 case of systemic inflammatory response syndrome. There was a significant difference in the incidence of complication between the two groups (χ2=4.122, P<0.05). The patients with infection were recovered after corresponding systematic conservative treatments. (3) Follow-up: of the 62 patients, 46 were followed up for 3-9 months, with a median follow-up time of 6 months, including 26 in the eco-immune group and 20 in the control group. During the follow-up, no complication or infection recurred in the two groups.@*Conclusion@#Compared with simple enteral nutrition, early postoperative enteral eco-immune nutrition in the nutritional support treatment is safe and effective for patients with intra-abdominal infection, which can enhance the immune function of patients, shorten the recovery time of patients, and reduce the incidence of infection complications.

ABSTRACT
Objective To evaluate the effect of enteral immune nutrition on the occurrence of acute kidney injury(AKI) in sepsis patients. Methods A retrospective study was conducted, 80 patients with sepsis admitted and treated in the intensive care unit (ICU) of Quzhou People's Hospital from January 2015 to December 2016 were enrolled, and according to different treatment programs, they were divided into an immune nutrition group and a standard nutrition group, each group 40 cases. The two groups received an equal amount of calories and nitrogen in enteral nutrition (EN). After treatment, the changes of serum total protein (TP), albumin (Alb), prealbumin (PA), hemoglobin (Hb), C-reactive protein (CRP), tumor necrosis factor-α (TNF-α), interleukin (IL-6, IL-10), infection site, length of stay in ICU, mortality in ICU, AKI incidence, AKI staging, etc in the two groups were observed. Results ① After treatment, the nutritional indicators TP, Alb, PA, Hb levels were significantly increased, the serum inflammatory factors CRP, TNF-α, IL-6 were obviously decreased and IL-10 was markedly increased in the two groups compared with those before treatment (all P < 0.05), the changes in the immune nutrition group were more obvious than those in the standard nutrition group [TP (g/L): 60.84±5.90 vs. 58.32±6.11, Alb (g/L): 33.95±3.83 vs. 31.79±3.44, PA (g/L): 0.24±0.04 vs. 0.21±0.03, Hb (g/L): 117.47±16.15 vs. 112.50±15.71, CRP (mg/L): 53.04±23.76 vs. 82.33±37.09, TNF-α (ng/L): 20.29±17.74 vs. 29.63±18.43, IL-6 (ng/L): 50.74±28.55 vs. 80.32±31.67, IL-10 (ng/L): 41.09±24.65 vs. 40.86±24.73]; ② The length of stay in ICU (days: 10.54±4.33 vs. 14.80±5.19), ICU mortality [15.00% (6/40) vs. 32.50% (13/40)] and the incidence of AKI [22.50% (9/40) vs. 47.50% (19/40)] of immune nutrition group were significantly lower than those of standard nutrition group (all P < 0.05); There were 9 cases of AKI mainly at stage I andⅡ (8 cases) in the immune nutrition group, while in the standard nutrition group there were 19 cases with AKI mainly at stageⅢ (11 cases). Conclusion The enteral immune nutrition can effectively reduce the incidence of AKI in sepsis patients, and the mechanism may be related to the immune nutritional preparation can inhibit the expressions of pro-inflammatory factors such as TNF-α, IL-6, etc.
ABSTRACT
Inflammation,immune suppression and oxidative stress is the main pathogenesis of sepsis.In recent years,more study have found ω-3 polyunsaturated fatty acid(ω-3PUFA) can inhibit inflammation by some mechanisms namely,reducing metabolites from arachidonic acid(AA) by competing with it through a variety of ways,alteration of membrane lipid rafts,inhibition of nuclear receptor activation(specifically nuclear factor NF-κB)to modulate production of inflammatory mediators,and metabolism into novel pro-resolving and antiinflammatory mediators (resolvins and protectins).In addition,ω-3PUFA can reduce oxidative stress by improvement the antioxidant defense system,etc.Many clinical studies have demonstrated that ω-3PUF is effective in the for sepsis patients.The paper reviews the specific mechanism of ω-3PUFA treatment for sepsis.
ABSTRACT
Glutamine is not only a special nutritional substance but a conditional essential amino acid,which is the most abundant amino acids in plasma,representing about 60％ of free amino acids in the body,and it's normal plasma concentration is from 0.6 to 0.9 mmol/L.In recent years,with the increasing deepening study of the field of clinical nutrition,the concept of glutamine study has been gradually changed gradually changed it's concept from a simple nutritional support to immune nutrition therapy.Glutamine can not only improve the body's protein levels of nutrition,protect the gastrointestinal mucosa,but also reduce the incidence of infection and the inflammation in the body,improve immune function,reduce side effects of chemotherapy,and at the same time enhance tumor sensitivity to chemotherapy and promote gastrointestinal cancer patients' postoperative recovery,reduce surgical complications.This paper aims to review the application and research of glutamine in the gastrointestinal cancer patients after the operation.
ABSTRACT
Objective To compare the efficacy and clinical value of early enteral immunonutrition (EIN) combined with glutamine with early standard formula enteral nutrition (EEN) in patients with severe acute pancreatitis(SAP).Methods Twenty-eight patients with SAP were divided into two groups by random number table.Both groups were fasted,given treatments of anti-infection,gastrointestinal decompression,acidoresistance,spasmolysis,pancreatic enzyme inhibition,reduce the burden on the pancreas insulin,water electrolyte balance and parenteral nutrition upon admission into hospital.Spiral nasointestinal tube was implemented within 72 hours of patients' admission.The 14 cases in the EEN group were given treatment of early standard enteral nutrition by nasojejunal tube.The 14 cases in the EIN group received early enteral immunonutrition (glutamine granules,0.2 g/(kg · d),at least three times oral administration by dissolving in enteral nutritious agent peptison with a small amount of warm water).During the treatment,the dose of glutamine granules was reduced gradually until withdrawal when the patients in the EIN group started normal diet.The changes were observed in patients in terms of APACHE Ⅱ,Ranson score,inflammatory markers,nutritional and immune indicators,while monitoring the first defecation time,ICU care unit stay,total hospital stay,total hospitalization costs,complication rate and mortality data.Results Patients of both groups tolerated early enteral nutrition treatment.Fourteen days after treatment,the value of the immune indicator IgG was significantly higher in the EIN group than in the EEN group((19.14 ± 2.03) g vs.(13.79 ± 3.29) g,P ＜0.05).The first defecation time,ICU care days,total hospital costs were significantly shorter or less in patients in the EIN group than in those in the EEN group (first defecation time:((4.29 ± 1.64) d vs.(5.36 ± 0.84)d,t =2.179 ; ICU care:(2.57 ± 0.85) d vs.(3.64 ± 1.60) d,t =2.213 ; total hospital costs:(343.6 ±35.9)thousand yuan vs.(438.6±94.3) thousand yuan,t =3.518; P ＜0.05).Conclusion It is feasible and safety to implement EIN treatment in patients with severe acute pancreatitis.EIN and EEN could significantly reduce the inflammatory response and improve the nutritional status of patients with severe acute pancreatitis.But EIN is better in improving immune function and the prognosis of patients with severe acute pancreatitis than the EEN.
ABSTRACT
BACKGROUND: Enteral immunonutrition (EIN) refers to addition of some specific nutrients in enteral nutrition (EN), which can help to increase the immune function, and reduce the inflammatory reaction and septic complications. This study aimed to determine whether EIN can improve the immune function in multiple trauma patients. METHODS: Thirty-two patients with multiple trauma who had been admitted to the general ICU of Changzheng Hospital, Shanghai, from March 2007 to May 2008, were randomly divided into two groups: an enteral immunonutrition group (EIN group, n=16) and an enteral nutrition group (EN group, n=16). EIN suspension (RuiNeng produced by Sino-Swed Co., Ltd) and ordinary nutrition liquid (RuiSu produced by Sino-Swed Co., Ltd) were given to patients of the EIN group and EN group respectively for at least for 14 days. Peripheral blood lymphocyte count (TLC), immunoglobulin (IgG, IgM, IgA), and T-lymphocyte subsets (CD3, CD4, CD8, CD4 / CD8) were detected on the 1st day after grouping, and the 7th day and 14th day after nutritional support. RESULTS: TLC, IgG, IgM, IgA, CD4 and CD4/CD8 ratio were significantly higher in the EIN group on the 7th and 14th day than that on the 1st day (P<0.05), and continually increased with a prolonged time of EIN. The parameters of immune function in the EN group on the 7th day didn't change significantly compared with those on the 1st day after grouping; on the 14 th day, TLC, IgG, IgM, IgA, CD4 and CD4/CD8 ratio were significantly higher than those on the 1st day after grouping (P<0.05), but were significantly lower than those in the EIN group on the 14th day (P<0.05). CONCLUSION: Compared with the general formula EN, EIN is more helpful for the recovery of humoral and cellular immune function in the early post-multitraumatic phase.
ABSTRACT
Objective To study the effects of enteral immunonutrition on immune function in patients with multiple trauma. Method A total of 32 patients with multiple trauma admitted to general ICU in ChangZheng hospital, Shanghai from March 2007 to May 2008 were randomly (random number) divided into two groups,enteral immunonutrition group (EIN group, n = 16)and the general formula enteral nutrition group (EN group, n = 16).Two groups of patients on the third day after injury began to accept the EIN and the general formula EN which respectively support at least 14 days. The patients peripheral blood lymphocyte count (TLC), immunoglobulin (IgG,IgM, IgA) ,and T-lymphocyte subsets (CD3, CD4, CD8, CD4/CD8) were detected on the day of the group formation, the seventh and the fortteenth day of the nutritional support. Results TLC, IgG, IgM, IgA, CD4 and CD4/CD8 ratio were significantly higher in EIN Group on the 7th and 14th day than that on the first day ( P ＜0.05), and extended with the EIN and sustained increase. All immunization indicators of EN group on the 7th day were no significant changes compared with the day of the group formation, and on the 14 th day TLC, IgG, IgM,IgA, CD4 and CD4/CD8 ratio were significantly higher than that on the day of the group formation ( P ＜ 0.05),but were significantly lower than that in the EIN group on the 14th day ( P ＜ 0.05). Conclusions Compared with the general formula EN, EIN is more helpful to restore and increase the humoral and cellular immune function in early post-multitraumatic phase.
