A CLINICAL CASE OF A NEW FORM OF BRONCHOPULMONARY DYSPLASIA

Bronchopulmonary dysplasia (BPD) is a polyetiologic chronic disease of morphologically immature lungs that develops in newborns, mainly in profoundly premature infants, as a result of intensive care respiratory distress syndrome (RDS) and/or pneumonia.

In recent years, improvements in premature infant care technologies have resulted in the survival of extremely low birth weight and very low birth weight infants. It is in these infants that the “new” form of BPD is currently diagnosed, which has a milder course and is associated with the cessation of alveolar and vascular pulmonary development. Despite advances in premature infant care in recent years, the incidence of BPD remains high, ranging from 7 to 80 % among premature infants depending on gestational age. Bronchopulmonary dysplasia is currently the most common chronic obstructive pulmonary disease in young children.

In the first months and years of life, BPD is characterized by pronounced respiratory symptoms, significant violations of ventilation and gas exchange function of the lungs and pronounced radiological changes. With age, in most cases, there is a decrease and disappearance of clinical symptoms and radiological changes, improvement or normalization of respiratory function. Some patients with moderate to severe BPD develop chronic lung diseases (emphysema, obliterating bronchiolitis, local pneumosclerosis, bronchiectasis) as a result of structural changes in the respiratory tract and lungs, which persist into adulthood. Bronchial asthma develops early in children with BPD, bronchial hyperreactivity and atopy. Children with a history of BPD are predisposed to recurrent respiratory viral and bacterial infections, and their exercise tolerance is impaired.

A retrospective analysis of medical case of an inpatient who was in the Department of Anesthesiology, Reanimation and Intensive Care of Newborns (OARITN), in the Department of Pathology of Newborns and Premature Infants No. 1 of the Perinatal Center and in the Pulmonology Department of the Pediatric Center of the State Autonomous Institution of the Republic of Sakha (Yakutia) “Republic Hospital № 1 – M. E. Nikolaev National Center of Medicine” was performed. The presented clinical case of a new form of bronchopulmonary dysplasia allows us to draw the attention of doctors to the course and outcome of this pathology.
