Surfactant dysfunction is a genetically heterogeneous pulmonary disease that causes dyspnea. ATP binding cassette protein transporter subunit A3 (ABCA3) is the main pathogenic gene of pulmonary surfactant dysfunction. In this study, we established an induced pluripotent stem cell line (SMCPGHi001-A) from the peripheral blood cells of a 49-day-old male infant, carrying compound heterozygous variations of the ABCA3 gene (c.3997_3998del, p.R1333fs, and c.3137C > T, p.A1046V). This iPSC line would be a useful tool to study the pathogenesis, disease development, and treatment of pulmonary surfactant dysfunction.

Since its outbreak, the novel coronavirus (COVID-19) has significantly impacted the pediatric population. Pulmonary surfactant dysfunction has been linked to other respiratory diseases in children and COVID-19 in adults, but its role in COVID-19 severity remains unclear. We hypothesized that elevated surfactant protein (SP) levels and single nucleotide polymorphisms (SNPs) of SP genes are associated with severe COVID-19 in children.

Key Clinical Message: Although the symptoms of accidental chlorine inhalation are typically mild, severe exposure can result in acute respiratory distress syndrome (ARDS). We present a case of pediatric ARDS due to chlorine exposure in which lung lavage and exogenous surfactant were successful in avoiding more invasive and costly treatments.
Abstract: Chlorine inhalation as a result of swimming pool chlorination accidents is relatively common.

Within the deep lung, pulmonary surfactant coats the air-liquid interface at the surface of the alveoli. This complex mixture of amphiphilic molecules and proteins modifies the surface tension and mechanical properties of this interface to assist with breathing. In this study, we examine the effects on pulmonary surfactant function by two industrially used compounds composing surfactants and polymers.

Background: Postoperative hypoxemia and pulmonary complications remain a frequent event after on-pump cardiac surgery and mostly characterized by pulmonary atelectasis. Surfactant dysfunction or hyposecretion happens prior to atelectasis formation, and sigh represents the strongest stimulus for surfactant secretion. The role of sigh breaths added to conventional lung protective ventilation in reducing postoperative hypoxemia and pulmonary complications among cardiac surgery is unknown.

Interstitial lung disease (ILD) comprises a group of respiratory diseases affecting the interstitium of the lungs, which occur when a lung injury triggers an abnormal healing response, and an inflammatory process leads to altered diffusion and restrictive respiratory dysfunction. The term "interstitial" may be misleading, as other components of the lungs are usually also involved (epithelium, airways, endothelium, and so on). Pediatric conditions (childhood interstitial lung disease, chILD) are different from adult forms, as growing and developing lungs are affected and more diverse and less prevalent diseases are seen in childhood.
