Summary
Treatment with corticosteroids, hydroxychloroquine, and azithromycin showed success in two of three pediatric patients with surfactant protein C (SP-C) dysfunction. This study highlights findings in a low-resource setting.
Area of Science:
- Pulmonary medicine
- Pediatric pulmonology
- Rare genetic disorders
Background:
- Pulmonary surfactant dysfunction disorders stem from genetic defects affecting surfactant metabolism.
- These rare conditions lead to significant morbidity and mortality in neonates and children.
Observation:
- This case series describes three pediatric patients with pulmonary surfactant dysfunction in Peru.
- Clinical, histopathological, and ultrastructural findings of the lamellar body suggestive of surfactant protein C (SP-C) dysfunction were observed.
- Video-assisted lung biopsy and ultrastructural studies were performed.
Findings:
- Treatment with monthly methylprednisolone pulses, daily hydroxychloroquine, and azithromycin was administered.
- Two out of three patients showed a good clinical response to the treatment regimen.
- One patient did not survive despite the therapeutic interventions.
Implications:
- This study contributes valuable data on SP-C dysfunction, particularly from low- and medium-income countries.
- The findings suggest a potential therapeutic approach for SP-C dysfunction in resource-limited settings.
- Further research is needed to optimize treatment strategies for these rare pulmonary disorders.

Breathing
59.4K
The process of breathing, inhaling and exhaling, involves the coordinated movement of the chest wall, the lungs, and the muscles that move them. Two muscle groups with important roles in breathing are the diaphragm, located directly below the lungs, and the intercostal muscles, which lie between the ribs. When the diaphragm contracts, it moves downward, increasing the volume of the thoracic cavity and creating more room for the lungs to expand. When the intercostal muscles contract, the ribs...

Cystic Fibrosis: Management
173
Cystic fibrosis (CF) is an autosomal recessive disorder that predominantly affects individuals of Northern European descent, occurring at a rate of 1 in 3500. It is caused by a genetic mutation in a gene on chromosome 7, most commonly the ΔF508 mutation, that codes for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. This results in thicker mucus secretions and obstruction pathologies in multiple organs, including the lungs and sinuses.

Cystic Fibrosis: Pathogenesis
254
Cystic fibrosis (CF), an autosomal recessive disorder, significantly affects the function of exocrine glands. This genetically inherited disease is characterized by the production of thick and sticky mucus, which can severely affect various organs and systems in the body.
CF is primarily caused by a genetic mutation in a chromosome 7 gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. The most common gene mutation leading to CF is the ΔF508 mutation,...

Pulmonary Cycle: Exhalation
1.6K
In terms of human respiration, the act of expelling air, known as exhalation (or expiration), operates on the principle of pressure gradients. During expiration, the pressure within the lungs exceeds that of the surrounding atmosphere. Under normal conditions, quiet breathing involves passive exhalation and is free of muscular contractions. This is because the exhalation process is driven by the natural elastic recoil of the lungs and chest wall, both of which have an inherent tendency to...

Acute Respiratory Failure-III
190
Hypercapnic respiratory failure, also known as Type 2 or ventilatory respiratory failure, is a severe condition characterized by the body's inability to effectively remove carbon dioxide (CO2) from the bloodstream. It leads to an arterial CO2 pressure (PaCO2) exceeding 45 mmHg and a blood pH above 7.35. This situation indicates that the body's ventilatory demand, or the ventilation needed to maintain normal PaCO2 levels, surpasses its supply or the maximum gas flow achievable without...

Acute Respiratory Failure-V
143
The treatment for acute respiratory failure varies based on factors like the underlying cause, overall health, and severity. A collaborative healthcare team is essential for early detection, often through arterial blood gas analysis. Identifying the cause is the primary goal, with treatment strategies adjusted for ventilation/perfusion (V/Q) mismatch, shunting, or diffusion impairment.
