Introduction

Bronchopulmonary dysplasia (BPD) is a chronic lung disease that primarily affects preterm infants, particularly those with very low birth weight. Despite advancements in neonatal care, BPD remains a significant cause of neonatal morbidity and mortality [1]. The condition is characterized by inflammation and scarring in the lungs, which impairs respiratory function and can lead to long-term health complications. Understanding the risk factors and symptomatology of BPD is crucial for developing effective preventive and therapeutic strategies. The etiology of BPD is multifactorial, involving a combination of genetic predispositions, prenatal and postnatal environmental influences, and clinical practices such as mechanical ventilation and oxygen therapy. Early identification of at-risk infants and the implementation of targeted interventions can significantly improve outcomes [2].

This comprehensive review aims to elucidate the risk factors and clinical manifestations of BPD in preterm infants, providing insights into current and emerging preventive and therapeutic approaches. We will explore the genetic, environmental, and clinical contributors to BPD development, as well as the various symptoms that characterize the disease. Special attention will be given to preventive measures, including optimized antenatal care, the use of non-invasive respiratory support, and early surfactant therapy [3]. Additionally, we will discuss therapeutic strategies that focus on managing respiratory function, providing adequate nutritional support, and utilizing pharmacological interventions. By synthesizing the latest research and clinical practices, this review seeks to enhance the understanding of BPD and improve the management of preterm infants at risk for developing this condition. Through a detailed examination of risk factors and symptomatology, we aim to identify key areas for intervention that can lead to better health outcomes and a higher quality of life for affected infants [4].

Discussion

Bronchopulmonary dysplasia (BPD) is a complex and multifactorial disease that continues to challenge neonatal care despite significant medical advancements [5]. This discussion delves into the risk factors, symptomatology, and current preventive and therapeutic approaches for BPD, highlighting areas where further research and clinical innovation are needed. The development of BPD is influenced by a combination of genetic, prenatal, and postnatal factors. Genetic predispositions play a critical role, as certain genetic markers have been associated with increased susceptibility to BPD. Prenatal factors, including maternal smoking, intrauterine growth restriction, and preeclampsia, also contribute to the risk. Postnatal factors, such as mechanical ventilation, oxygen therapy, and infections, significantly impact the incidence and severity of BPD. Minimizing exposure to these risk factors through targeted interventions is essential for reducing the prevalence of BPD in preterm infants [6].

BPD's clinical manifestations are varied and can range from mild respiratory distress to severe chronic lung disease. Common symptoms include tachypnea, retractions, wheezing, and hypoxemia. These symptoms can persist into childhood and adolescence, leading to long-term respiratory issues such as reduced lung function, increased susceptibility to respiratory infections, and the potential development of asthma-like conditions. Early identification and continuous monitoring of these symptoms are crucial for timely intervention and management. Preventive strategies for BPD focus on minimizing the exposure to known risk factors. Antenatal steroids have been shown to accelerate fetal lung maturity and reduce the incidence of respiratory distress syndrome, a precursor to BPD. Non-invasive ventilation techniques, such as continuous positive airway pressure (CPAP), are preferred over mechanical ventilation to reduce lung injury. The early administration of surfactant therapy helps improve lung function and decrease the need for invasive respiratory support. Additionally, optimizing maternal health through smoking cessation programs and managing conditions like preeclampsia can further reduce the risk of BPD [7].

Managing BPD requires a multifaceted approach that addresses both acute and chronic aspects of the disease. Respiratory support remains a cornerstone of BPD management, with strategies evolving to minimize lung injury while ensuring adequate oxygenation and ventilation. High-flow nasal cannula (HFNC) and non-invasive ventilation are commonly used to support infants with BPD. Pharmacological interventions, such as diuretics, bronchodilators, and corticosteroids, can help manage symptoms and improve lung function. Nutritional support is critical for promoting growth and development, with a focus on providing adequate calories and nutrients to support lung repair and overall health. Emerging therapies, including stem cell therapy and anti-inflammatory treatments, hold promise for more effective management of BPD [8]. Stem cell therapy aims to repair and regenerate damaged lung tissue, while anti-inflammatory treatments target the underlying inflammation that contributes to BPD development. Ongoing research into the genetic and molecular mechanisms of BPD will further elucidate potential targets for intervention.

Despite advances in understanding and managing BPD, several challenges remain. The variability in clinical practices and the lack of standardized protocols can lead to inconsistent outcomes. Additionally, the long-term follow-up of BPD patients is often limited, impacting the ability to monitor and manage chronic complications. Addressing these challenges requires the development of standardized treatment guidelines, increased awareness of BPD's long-term impact, and enhanced support systems for families [9]. By focusing on early identification, minimizing exposure to risk factors, and implementing evidence-based management strategies, healthcare providers can improve outcomes for preterm infants at risk for BPD. Continued research and innovation are essential for advancing our understanding and treatment of this complex condition, ultimately leading to better health outcomes and quality of life for affected infants [10].
