The article presents the results of a clinical investigation on the administration of the Grippol Quadrivalent vaccine (influenza tetravalent inactivated subunit adjuvant vaccine) in children from 6 months to 5 years old. The vaccine has demonstrated no less effectiveness in comparison with the Grippol plus vaccine (influenza trivalent inactivated polymer-subunit vaccine).comparable results were obtained for all evaluated indicators of immunological efficacy against matching strains of the influenza virus, while for additional strain B (Yamagata line) there was a statistically significant difference in the increase in the immune response in the Grippol Quadrivalent group. The results of the assessment of the reactogenicity and frequency of systemic adverse events indicated a favorable and comparable safety profile of the vaccines Grippol Quadrivalent and Grippol plus in children from 6 months to 5 years old. The data obtained allowed us to conclude that the immunological efficacy of the Grippol Quadrivalent vaccine is no less when compared to the Grippol plus vaccine, as well as a comparable safety and reactogenicity profile. According to the results of the clinical investigation, on 08/04/2023, the Ministry of Health of the Russian Federation amended the “Instructions for the medical use of the drug”: Grippol Quadrivalent is indicated for children from the age of 6 months.

The publication is devoted to the review of accumulated data on the relationship of respiratory allergopathology with neuropsychiatric disorders in childhood. The immediacy of the problem is due to the mutual influence of allergic and neuropsychiatric conditions combined in a child on the course of these diseases. According to research, the connection of respiratory allergic diseases with disorders of neurodevelopment, in particular with attention deficit and hyperactivity disorder and autism spectrum disorders, is clearly manifested, and the first publications on the connection with speech and other mild cognitive impairments have appeared. At the same time, the formation of depression, suicidal behavior, and anxiety disorders in respiratory allergopathology is being actively studied. It is assumed that the close relationship between nervous and immune regulation provides a high correlation of allergic and neuropsychiatric pathological conditions, although cause-and-effect relationships have not yet been precisely established. In this regard, it becomes relevant to introduce into clinical practice monitoring of cognitive status, neuropsychic development and possible symptoms of anxiety, depression and suicidal thoughts in the treatment of children with respiratory allergic diseases. Timely detection of violations will make it possible to provide specialized interventions at an early stage in order to achieve a favorable treatment result in the long term.

The discovery of immune checkpoints (IC) has become a landmark event in immuno-oncolog y, improving the understanding of the mechanisms of tumor cells evading immune sur veillance. Based on this, a group of drugs such as immune checkpoint inhibitors (ICIs) were developed, the ef fect of which is due to the rupture of the immunological synapse and recognition by tumor T cells. Currently, ICIs are successfully used in the treatment of a number of malignant neoplasms, improving the indicators of diseasefree and overall sur vival. However, determining the role of these drugs in the treatment of children with tumors of the blood system is the subject of active research. This article presents a review of the literature on topical aspects of the administration of PD-1 and PD-L1 inhibitors in pediatric hematolog y. Their mechanisms of action, ef fectiveness and potential complications of therapy are presented.

In recent years, there has been a significant increase in the prevalence of inflammatory bowel diseases. Despite the significant progress made in the instrumental diagnosis of this group of diseases, their treatment in most cases remains formalized, based on fairly strict schemes. In this context, an urgent area of modern research is to study the effectiveness of the use of diet therapy and certain foods in order to modulate the activity of the inflammatory process, which allows avoiding adverse reactions of immunosuppressive, including immunobiological, therapy. Adherence to the Mediterranean diet has proven its effectiveness in the treatment of chronic non-infectious diseases. Recent studies have also established its benefits in the treatment of inflammatory bowel diseases. Recent studies have also established its benefits in the treatment of inflammatory bowel diseases. This article will present the results of modern research on the effect of the use of olive oil and its components on the course of inflammatory processes in the intestine. A number of studies conducted in vitro and in animal models have revealed the mechanisms by which olive oil and its components have a positive effect on the course of inflammation in the intestinal wall through anti-inflammatory, antioxidant, immunomodulatory and antitumor effects. Few clinical studies conducted on patients with inflammatory bowel diseases have shown the possibility of using diet therapy with the addition of olive oil in this group of patients as an additional treatment.

Psoriasis is the second most common skin disease after atopic dermatitis in childhood. There are factors affecting both the manifestation and aggravation of this inflammatory skin process. The leading role in the psoriasis pathogenesis is currently associated with key cytokines. However, infectious diseases could be the triggers for psoriasis.

Nowadays, the approach to psoriasis management in children has been revised due to emerging of new knowledge about the clinical manifestations and the role of numerous comorbid conditions in psoriasis course. Risk factors assessment, as well as evaluation of potential comorbidities signs and symptoms, is crucial part in patient management to create a prognostic model of the disease progression and the aggravation development (with underlying associated inflammatory processes included).

Glycogen storage disease refers to hereditary pathologies of carbohydrate metabolism, its cause is mutations of various genes encoding enzymes responsible for the synthesis and breakdown of glycogen. Due to enzyme defects, excessive glycogen deposition occurs in cells of various tissues, mainly in the liver and muscles. The authors present modern epidemiological data and features of the etiopathogenesis of glycogen storage disease, and give clinical characteristics of various types of this nosology. In accordance with the developed clinical guidelines, information is provided on laboratory, instrumental and morphological signs of glycogen storage disease in children, as well as on methods of treatment of glycogen storage disease. Due to the variety of clinical forms of glycogenosis, the article provides up-to-date information on three types of pathology that occur with predominant liver damage.

This review presents an analysis of the literature data for the last 10 years (2012–2022) investigating the effect of eating disorders on the health of adolescent girl, its diagnosis, and possible tactics of gynecologist. The most common predictor of restoring menstrual function in girls with this pathology is body mass index change, however normalization of weight does not lead to remission in all cases. Thus, estimation of fat percentage, insulin-like growth factor, and leptin is more effective. We suggest directing further research on the study of more effective methods of reproductive disorders correction and the development of multidisciplinary clinical guidelines for the effective diagnosis and management of eating disorders and any gynecological complications.
