Neonatal sepsis is one of the major causes of mortality and morbidity in newborns, greatly associated with severe acute kidney injury (AKI) and failure. Handling of newborns with kidney damage can be significantly different compared to adults, and it is necessary to consider the individuality of an organism’s response to systemic inflammation. In this study, we used lipopolysaccharide (LPS)-mediated acute kidney injury model to study mechanisms of kidney cells damage in neonatal and adult rats. We found LPS-associated oxidative stress was more severe in adults compared to neonates, as judged by levels of carbonylated proteins and products of lipids peroxidation. In both models, LPS-mediated septic simulation caused apoptosis of kidney cells, albeit to a different degree. Elevated levels of proliferating cell nuclear antigen (PCNA) in the kidney dropped after LPS administration in neonates but increased in adults. Renal fibrosis, as estimated by smooth muscle actin levels, was significantly higher in adult kidneys, whereas these changes were less profound in LPS-treated neonatal kidneys. We concluded that in LPS-mediated AKI model, renal cells of neonatal rats were more tolerant to oxidative stress and suffered less from long-term pathological consequences, such as fibrosis. In addition, we assume that by some features LPS administration simulates the conditions of accelerated aging.

Oxidative kidney injury was compared in newborn and adult rats under conditions of ischemia/reperfusion and in experimental model of systemic inflammation induced by endotoxin (LPS of bacterial cell wall) administration. Oxidative stress in the kidney accompanied both experimental models, but despite similar oxidative tissue damage, kidney dysfunction in neonates was less pronounced than in adult animals. It was found that neonatal kidney has a more potent regenerative potential with higher level of cell proliferation than adult kidney, where the level proliferating cell antigen (PCNA) increased only on day 2 after ischemia/reperfusion. The pathological process in the neonatal kidney developed against the background of active cell proliferation, and, as a result, proliferating cells could almost immediately replace the damaged structures. In the adult kidney, regeneration of the renal tissue was activated only after significant loss of functional nephrons and impairment of renal function.

The aim of this review is a detailed description of the alleged mechanisms of involving the adrenal glands, as a key element of the system of nonspecific protection of an organism and adaptation to stress, in the pathogenesis of clinical manifestations of acute small bowel obstruction and developing complications, including peritonitis, sepsis and multiple organ failure. In the discussion of the pathogenesis of clinical manifestations of acute small bowel obstruction and its complications, leading to the disappointing results of treatment of patients on a large sample of contemporary scientific publications, it is noted that many researchers see a close connection between the influence of various stress effects on humans and the functioning of internal organs and systems. It is demonstrated that in the literature there is growing evidence of the negative effects of stress and related affective disorders on the course of inflammatory bowel diseases and gastrointestinal tract, which is one of the targets of stress, and hormones of the hypothalamicpituitary- adrenal system, especially the adrenal glands take an active part in the mediation of these reactions. The conducted analysis of the current literature demonstrates a large number of unsolved issues in this direction, that proves the need for a comprehensive experimental and morphological studies to clarify and detail all pathogenetic links of dependent morpho-functional transformations in the dynamics of development of acute small bowel obstruction which may lead to adrenal insufficiency and disruption of adaptation mechanisms that maintain the stability of homeostasis.

To specify the frequency and species composition of vaginal bacterial carriage in pregnant women at the term of gestation 35–37 wks. Patients and methods. We examined 800 pregnant women, who were followed-up on an outpatient basis at terms of gestation 35–37 wks. Cultural examination of the content of the posterior vaginal fornix was performed. Species identification of microorganisms was performed by the method of direct protein profiling with the help of MALDI-TOF mass spectrometry, FLEX series, Bruker Daltonic GmbH, Germany. Results. The growth of flora was obtained in 761 patients (95%). Bacterial vaginosis (n = 71), Candida vulvovaginitis (n = 83) were diagnosed in 154 patients (19%). Lactobacillus spp. were found in 80% (n = 637) of examined women, of them in 161 (20%) in monoculture. Bacterial carriage was diagnosed in 55.8% of cases. The prevalence of Enterococcus faecalis, Escherichia coli, Streptococcus agalactiae, Staphylococcus epidermidis and Staphylococcus haemoliticus was noted. They were much more rarely detected in monoculture: E. faecalis (1%), S. agalactiae (0.1%), S. epidermidis (0.1%), Candida albicans (0.1%). In 39 (5%) patients, no growth of flora was found. In 17 patients we found extended-spectrum B-lactamase-producing bacteria: E. coli (n = 15), Klebsiella pneumoniae (n = 2). Conclusion. Taking into account a high prevalence of vaginal bacterial carriage in pregnant women in the 3rd trimester, it might be expedient to consider inclusion of microbiological examination of vaginal discharge in the basic spectrum of antenatal observation and screening examination of pregnant in the Russian Federation.

Today the «Surrogate motherhood» programme is actively developing and every year becomes a more and more needed method of assisted reproductive technologies. But the findings of recent scientific research have shown that the course of pregnancy in surrogate mothers is associated with an increased incidence of obstetric complications. A clinical case of antenatal fetal death and development of sepsis in a 32-year-old woman, whose pregnancy occurred after IFV under a surrogacy programme is presented.

A retrospective analysis included 31 patients aged 23 to 78 years with the signs of SIRS from the departments of therapy, pulmonology and the intensive care unit (ICU) with the diagnosis of severe community-acquired or hospital-acquired pneumonia. The plasma level of presepsin protein was assessed using the Pathfast immunochemiluminescence analyzer (Japan). It was revealed that at hospitalization, the level of PSP was significantly higher in patients with SIRS than in healthy individuals. Patients with the diagnosis of sepsis (later confirmed by hemoculture) showed a higher concentration during hospitalization and at all subsequent time points of the study, which characterizes presepsin as a marker of sepsis in difficult clinical settings.

Therapeutic plasma exchange (PE) is a procedure of removing and replacing a large volume of plasma with various biologically active substances that have a pathological effect on the patient. Plasma exchange in some diseases is one of the components of pathogenetic therapy (ANCA-associated systemic vasculitis, antiphospholipid syndrome, Goodpasture's syndrome, thrombotic microangiopathy, etc.). PE removes circulating immune complexes damaging tissues and organs and restores the coagulation system. In the practical recommendations of the American Apheresis Society (2016) leading experts in the field of apheresis therapy, based on an analysis of numerous clinical studies, gave clear recommendations to use the apheresis technologies for extracorporeal detoxification. Also 4 categories of indications and contraindications, assessing the benefits of carrying out apheresis procedures for a specific nosology were specified. A number of new diseases have been introduced, such as atopic (neuro) dermatitis (atopic eczema), cardiac neonatal lupus, Hashimoto encephalopathy, HELLP syndrome, in which PE is one of the leading therapeutic approaches as well as cytotoxic and glucocorticosteroid therapy. However, the use of plasma exchange in the treatment of some diseases remains controversial, for example, sepsis. So further research is needed.

In the modern clinic of internal diseases, the specific gravity of the infectious pathology, manifested by various clinical syndromes, is increasing. Infectious pathology is represented by diseases of the respiratory system, heart disease (infective endocarditis, cardioimplant infections, viral myocarditis), infectious arthropathies, extrahepatic manifestations of viral hepatitis, cytopenic syndromes, various manifestations of sepsis and some other conditions.In most cases, the diagnosis and management of such patients is the responsibility of the internist, who must be able to suspect the infection and carry out its verification. In the process of diagnostic search and management of patients, close interaction of the internist with a clinical microbiologist, clinical pharmacologist and other related specialists is necessary.

In this survey, we would like to emphasize the importance of the control over the activation over the compliment system. It has been proved of animal model a complement one of the key role in the development of hyperactive immunity response, later resulting in violation of immunity homeostasis. Mice which had C3-/-, C4-/-deficit, aft receiving a LPS dose intraperitoneallis showed a better survival to compare with the control group of animals. There exist clinical data which confirm active participation of the compliment in the chain of the septic process. The research showed the patient affected by sepsis, had protein C3 and C4 concentration correlating which mortality at the time of diagnosis. The is chemoattractants, protein C3a and C5a, turn tube the result of complements pathway activation. The chemoattractants, provoke the extraction a big number of cytokines. Vessels permeability increase and DIC-syndrome activation wis it, multiple organ dysfunction develops. Ishemiareperfusion launch triggers aseptic inflammation, which appears decentralization and DIC-syndrome. C1-INH controls the work of classical way complement and Hemostasis System. Researchers the deficit in C1-INH animals and patients affected bay sepsis, which is proved in laboratory and clinics. The remedy C1-INH (Berinert, CSL Behring) appeared over 25 years ago and was used and therapy hereditary angioedema. For the lasted years we accumulated a considerable quantity of fasts of C1-INH use which after pathologies: heart attack, Ischemia-reperfusion injury, trauma provoked by cardiopulmonary bypass. The use of C1-INH on animal models septic in clinical research their efficacy and safety.
