Mother’s own milk is the optimal food for infants. It is characterized not only by a unique balanced composition of nutrients, but also by essential biological properties, which is especially important for preterm infants. If there is no mother’s milk or it is amount is not enough to meet daily needs, it is recommended to use donor human milk (HM) instead. However, donor HM is commonly obtained from the women who delivered at term and often does not contain enough protein to promote proper growth of preterm infants. Whether donor milk or the mother’s own milk, human milk fortifi cation is essential to meet the nutrient needs for growth and development of these preterm infants, who are at high risk of growth retardation during hospital stay. There are several strategies and commercially available HM fortifi ers that can be used to maintain the desired growth rate. Standard HM fortifi cation, which is currently most commonly used in neonatal intensive care units, may not meet the increased protein needs of a signifi cant proportion of very low birth weight infants.Instead, individualized fortifi cation can optimize nutrient intake. It is possible to individualize the food supply with the help of regulated or targeted HM fortifi cation. The quality and origin of commercially available HM fortifi ers are also important. To implement an individualized approach to the fortifi cation of HM, the use of milk analyzers can be useful. However, the clinical benefi ts of individual approaches to breast milk fortifi cation and the use of diff erent commercially available HM fortifi ers remain largely unknown. This review presents the results of the most important studies that infl uence clinical practice and describes current approaches to HM fortifi cation with relevant practical recommendations.

Introduction. According to the World Health Organization (WHO), the incidence of preterm birth is 10-15%, or about 15million newborns worldwide, and this number is increasing. The highest incidence of morbidity and mortality is observed ininfants born before 32 weeks of gestation. Among other things, preterm infants have an immature digestive system, which leads to food intolerance. The formation of cumulative nutrient defi ciencies in the digestive system from birth puts children at risk of delayed psychophysical development and contributes to the development of negative long-term neurological consequences.Many of these complications have lifelong consequences for health, growth and development, both in infancy and later in life.Aim of the study. To improve the diagnosis of intestinal dysfunction in perinatal pathology in premature infants based on thestudy of risk factors and clinical and laboratory parameters.Materials and methods of the study. A comprehensive clinical and paraclinical examination of 91 premature infants withclinical manifestations of moderate and severe perinatal pathology with signs of disturbances of the functional state of thedigestive system (group I, gestational age 29 (0/7) – 36 (6/7) weeks) and 57 conditionally healthy newborns (group II, gestationalage 35 (0/7) – 36 (6/7) weeks) was performed. The total number of children studied was 148. Exclusion criteria were childrenwith congenital malformations and septic conditions.The list of laboratory parameters used included: levels of α-1-antitrypsin (A1AT), PMN-elastase, albumin, fecal calprotectin(FC) and fecal elastase-1 (FE-1) in children’s stool using enzyme- linked immunosorbent assay (ELISA), reagents fromImmundiagnostic AG (Germany) on the basis of the German- Ukrainian laboratory “BUKINMED” (Chernivtsi, Ukraine).The scientifi c work was carried out on the basis of neonatology departments of the Chernivtsi City Clinical Maternity Hospitalin 2014-2018. Informed consent of the parents of the child was obtained with adequate explanation of the purpose, objectives,methods and scope of laboratory and instrumental research methods. The study protocol was approved by the Biomedical Ethics Commission of the Bukovinian State Medical University, 2015.The studies were conducted in accordance with the basic provisions of GCP (1996), the Convention of the Council of Europeon Human Rights and Biomedicine (April 4, 1997), the World Medical Association Declaration of Helsinki on Ethical Principlesfor Research Involving Human Subjects (1964-2008), Order of the Ministry of Health of Ukraine ¹ 690 dated September 23, 2009(as amended by Order of the Ministry of Health of Ukraine ¹ 523 dated July 12, 2012).Statistical processing of data was performed using the software “STATISTICA” (StatSoft Inc., USA, version 10), programMedCalc (https://www.medcalc. org/index.php). Comparison of quantitative indicators with normal distribution was performedusing Student’s t-test. The diff erence in parameters was considered statistically signifi cant at p<0.05.The thesis was carried out within the framework of the scientifi c topics of the Department of Pediatrics, Neonatology andPerinatal Medicine of the Bukovinian State Medical University: Research work on “Improvement of directions of prognosis,diagnosis and treatment of perinatal pathology in newborns and infants, optimization of schemes of catamnestic observationand rehabilitation” (State registration number 0115U002768, term of execution 01. 2015-12. 2019); Research work on“Chronobiological and adaptive aspects and features of autonomic regulation in pathological conditions in children of diff erentage groups” (State registration number 0122U002245, term of execution 01.2020-12.2024).Results and discussion. The studied laboratory parameters of stool in premature infants with signs of food intolerancein perinatal pathology revealed certain pathophysiological mechanisms of its development, including acute infl ammation,increased permeability of the intestinal mucosa, and exocrine insuffi ciency. Dysfunction of the digestive system is a consequence of complex autonomic and visceral dysfunction of the child’s body against the background of hypoxia and morphological and functional immaturity at birth. An increase in the level of A1AT, PMN-elastase, albumin and a decrease in the concentration of FE-1 in feces are interdependent criteria of digestive system dysfunction. Increased permeability of the intestinal mucosa in conditions of local infl ammation leads to translocation of pathogenic and opportunistic microorganisms into the bloodstream, which probably exacerbates the clinical manifestations of endotoxemia in perinatal pathology of premature infants. The above justifi es the need to continue scientifi c research to develop a refi nement of comprehensive diagnosis and correction of digestive function in preterm infants.Conclusions.1. Premature birth of children causes a high risk of adaptation disorders in newborns, which is due to the morphologicaland functional immaturity of the body and the realization of perinatal risk factors.2. In the complex of vegetative- visceral dysfunction in conditions of perinatal pathology in newborns, there are signs ofcombined dysfunction of the digestive system, which is characterized by weakening or absence of sucking refl ex, regurgitation,intestinal stasis and paresis, delayed passage of meconium and transitional stools, fl atulence; in the most severe cases, persistent and prolonged decrease in tolerance to enteral nutrition is one of the characteristic manifestations of SIDS.3. Increased levels of A1AT, PMN-elastase, albumin and decreased concentration of FE-1 in feces of children with nutritionaldysfunction in the complex of signs of perinatal pathology are laboratory confi rmation of digestive system disorders in premature birth. 4. The pathophysiological mechanisms of transient disorders of the functional state of the digestive system, which causeclinical signs of food intolerance, are: acute infl ammation, increased permeability of the intestinal mucosa and exocrineinsuffi ciency. Increased permeability of the intestinal mucosal barrier leads to increased translocation of pathogenic andopportunistic microorganisms into the bloodstream, which contributes to the growth of endotoxemia in perinatal pathology ofpremature infants.5. Harmonization of clinical and paraclinical criteria for disorders of the functional state of the digestive tract in the complexof perinatal pathology will increase the eff ectiveness of diagnostic measures in the neonatal period, especially in prematureinfants, and improve approaches to medical care by improving the range of diagnostic and therapeutic measures.

Premature babies in early postnatal ontogenesis are characterized by the immaturity of many functional systems, including the digestive system. The imperfection of the motor-evacuation function of the gastrointestinal tract in them is combined with insufficient activity of the enzyme systems, the peculiarities of the formation of the microbial landscape of the colon, which contributes to the development of digestive dysfunctions and complicates enteral feeding, especially in deeply premature infants. In order to determine the parameters pancreatic elastase (PE) in premature infants, depending on the gestational age and the nature of feeding, 135 newborns were examined (108 premature infants with a gestational age of 22 to 32 weeks and 27 term infants). All children underwent a general clinical examination, as well as a study for PE on the 13–14th day of life, when the volume of enteral nutrition reached 70 percent or more. Analysis of the study results revealed a clear relationship between the degree of prematurity and the severity of pancreatic insufficiency. A clear relationship between fecal elastase indicators and the type of feeding was determined. The most favorable situation is observed in exclusively breastfed children, who have the highest fecal elastase values, which practically do not differ from the control values. The research was carried out in accordance with the principles of the Helsinki Declaration. The study protocol was approved by the Local Ethics Committee of these Institutes. The informed consent of the patient was obtained for conducting the studies. No conflict of interest was declared by the authors. Key words: premature, elastase, pancreatic insufficiency.
