Abstract

To review the prevalence, clinical features, and role of bronchoscopy in patients with plastic bronchitis during the acute chest syndrome (ACS) of sickle cell disease (SCD). Eight-year review of clinical experience. Tertiary referral children's hospital. Twenty-six pediatric inpatients with 29 ACS episodes requiring diagnostic bronchoscopy. Of the pediatric inpatients with ACS who underwent bronchoscopy, plastic bronchitis was diagnosed in 21 of 29 episodes (72%). There was no difference in clinical features between the patients with and without plastic bronchitis. Bronchoscopy was an essential diagnostic tool, but its therapeutic benefits were doubtful. This is the first report of the prevalence of plastic bronchitis in patients with ACS of SCD. In our patient population, this condition was found to be common. The role of diagnostic bronchoscopy is essential. A large series, multicenter study is required to determine whether bronchoscopy and BAL are therapeutically beneficial when added to currently practiced supportive care.

Summary

Methods

We reviewed our personal experience (C.M., E.N.) and medical records of pediatric inpatients with ACS who underwent bronchoscopy at Miller Children’s at Long Beach Memorial Medical Center in Long Beach, CA, over the past 8 years. Long Beach Memorial Medical Center has an active SCD treatment center currently caring for approximately 240 patients. Bronchoscopy report, imaging studies, and laboratory results were reviewed. The authors (C.M., E.N.) were involved in the care of each patient and performed fiberoptic bronchoscopy and BAL as previously described.[6] Descriptive statistical analysis was used, and data are presented as median, mean, SE, range, percentage, and risk ratio. All mean values are reported with 95% confidence levels. Comparisons between the group with plastic bronchitis and group without plastic bronchitis were calculated using unpaired Student’s t test
