A severe early presentation of cystic fibrosis in an infant with a homozygous c.1375_1383del CFTR variant- a case report.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Cystic fibrosis is a genetic disease affecting mainly the respiratory and digestive systems through CFTR gene mutations. The condition is characterized by the production of thick mucus, which can lead to severe respiratory complications and pancreatic insufficiency.We report a rare homozygous c.1375_1383del CFTR variant associated with early, clinically significant presentation. This highlights the importance of early recognition and genotype-specific management to maximize patient outcomes and improve quality of life. Case Report: We present a 10-month-old female infant born to consanguineous parents with a significant medical history of chronic cough, cyanosis, failure to thrive, poor feeding, and irritability who ultimately required multiple hospitalizations for severe infections requiring mechanical ventilation and intravenous antibiotics. Initial evaluations included thorough clinical assessments and several diagnostic tests, including whole-exome sequencing, which revealed a homozygous c.1375_1383del variant in the CFTR gene. Aggressive therapy, including antipseudomonal antibiotics, was needed to clear the infection, in addition to administration of dornase alpha, 7% hypertonic saline, and pancreatic enzyme replacement therapy. These interventions contributed significantly to the gradual clinical improvement of the patient. At 18-month follow-up, the patient exhibited improved weight gain and a reduction in the frequency of exacerbations. Conclusion: The c.1375_1383del variant is a rare CFTR variant and is associated with early, clinically significant manifestations of cystic fibrosis in infants, which necessitates early recognition and aggressive management to improve patient outcomes. This case underscores the need for awareness of rare CFTR variants and their potential clinical implications, which can lead to tailored treatment approaches, ultimately enhancing the quality of life for affected individuals.
