Muramyl dipeptide β-heptylglycoside (C7MDP) was administered to non-pregnant CBA female mice and pregnant mice after non-abortion-prone mating (CBA×BALB/c) and mating associated with a high rate of spontaneous abortion (CBA×DBA/2). In non-pregnant females, C7MDP increased the production of IL-2, IL-4, IL-5, IL-6, IL-17, IFNγ, TNFα, and GM-CSF at constant production of IL-1α and IL-10. C7MDP increased the production of IL-10 and IL-17 and suppressed the production of IFNγ on day 8 of gestation in non-abortion-prone mouse couples and stimulated the synthesis of IL-4 and IFNγ, reduced IL-5 production, and slightly increased IL-1α secretion after abortion-prone mating. On day 14 of gestation, C7MDP elevated the yield of IL-2, IL-4, IFNγ, TNFα, and GM-CSF in CBA×BALB/c and CBA×DBA/2 couples and IL-17 in the fi rst variant of mating.
The aimof this prospective randomized clinical study was to investigate the role of preoperative carbohydrate admnistration in surgery-induced metabolic, immune and inflammatory reactions after thoracoabdominal operations. At the Surgical department I (B.V. Petrovsky National Research Center of Surgery), we investigated a modulatory role of carbohydrate preload upon surgical stress observed after major thoracoabdominal operations (thoracoscopic and open esophagectomy, retrosternal colonic esophagoplasty) followed by the enhanced recovery protocol. The study was performed in 2014-2017, it included 30 patients, divided into 2 groups. Group A patients (n = 16) received carbohydrates preload (12.5% maltodextrin solution per os or enterally). In patients with dysphagia, the 12.5% dextrose solution was used intravenously in equal volumes. Group B patients didn’t receive any additional preload with carbohydrates. The groups were age- and gendermatched, similar for disease and surgery types. Glucose and insulin levels (with HOMA insulin resistance index, HOMA-IR) were measured before surgery and on day +1, interleukin levels (IL-6, IL-10, IL-8) and index IL-8/IL-10 were assessed before surgery, and on days +1 and +5 after surgery. Cell-mediated immunity was investigated before surgery and on day +5.The stress-induced hyperglycemia (> 7.8 mmol/L) was detected more frequently in group B (50%), than in group A (6%), p = 0.012. Insulin resistance measured by HOMA-IR in group B was detected in 71% of patients and in 25% patients of group A only, p = 0.027. Individual analysis of immune response demonstrated that a trend for immune recovery was detected by the day +5 post-op in the group A. Postoperative levels of IL-6 and IL-10 were lower on day +1 and +5 in group A. Morbidity rates and the terms of hospitalization were similar in both groups. Local postsurgical infections in group A were developed in 6% of the patients vs 35.6% in group B (p = 0.072).In conclusion, a complex study of surgical stress, i.e., metabolic, immune and inflammatory reactions after esophageal surgery has shown that the carbohydrate preload decreased the incidence of postoperative insulin resistance and stress-induced hyperglycemia, being accompanied by lower release of proinflammatory cytokines and provides positive effects upon the patient’s immune system.

Oroanthral fistula (anastomosis) is an element preventing the restoration of homeostasis in the maxillary sinus due to the constant flow of microbes from the oral cavity. It is also contributes to frequent exacerbations of maxillary sinusitis. Saprophytic gram-positive cocci and fungi of the oral cavity are dominating representatives of the microbial flora in the maxillary sinus. As the result of research, we found that in the case of maxillary sinusitis with oroantral fistula fungi made up 25.0% of microbiota, gram-positive bacteria – 41.7%, gram-negative bacteria – 33.3%. Gram-positive cocci from the Staphylococcus genus (Staphylococcus aureus and Staphylococcus epidermidis) and fungi (Candida albicans) comprised the biggest proportion of microbial flora that 33.3% and 16.7%, respectively. Slightly decreased levels of monocytes in venous blood was noted in 69.2% of patients. The average value of total serum IgE in group with oroantal fistula was 226.2 (70.4) IU/ml, the result exceeded normal limits almost in 2.26 times. Large circulating immune complexes (CICs) were normal in all patients in the group with iatrogenic maxillary sinusitis. The average lavels of small size CICs was 170.2 (4.23) ОU, which is in 1.06 times higher the upper limit of the norm (160 ОU). Elevated levels of total Ig E in serum of patients with oroanthral fistula indicates allergic sensitization. The detection of increased levels of CICs with small and medium sizes in serum may indicate a susceptibility of this category of patients to the development of immunopathological reactions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
