Evaluation of the pulmonary radioaerosol mucociliary clearance scan as an adjunctive test for the diagnosis of primary ciliary dyskinesia in children.

Pediatric Pulmonology 2019 December
INTRODUCTION: The accuracy of primary ciliary dyskinesia (PCD) diagnosis has improved but no single test is diagnostic and some cases remain unsolved. Data regarding the accuracy of pulmonary radioaerosol mucociliary clearance scan (PRMCC) for the diagnosis of PCD are limited to predominantly adults using a 24-hour test. This study was performed to determine the accuracy of a 60-minute PRMCC test for diagnosing PCD in children.

METHODS: Children with suspected PCD and inconclusive clinical diagnostic testing in an expert center were selected for PRMCC testing. Nebulized 99m Tc sulfur colloid was inhaled and dynamic imaging acquired for 60 to 120 minutes. Two independent radiologists blinded to the clinical diagnosis and health records overread PRMCC studies. The PRMCC result was compared with the reference standard diagnosis of PCD made by two physicians using the cumulative health record, blinded to PRMCC results.

RESULTS: From 2008 to 2018, 57 patients (6-17 years) participated, of which 16 met criteria for the reference diagnosis of PCD. The PRMCC test was conclusive in 54 patients (94.7%) and had a sensitivity of 100% (95% confidence interval [CI] = 78.2-100), specificity of 85.7% (95% CI = 69.7-95.2), positive predictive value of 75% (95% CI = 57.1-87.1), negative predictive value of 100% (95% CI = 90.2-100), and accuracy of 90% (95% CI = 78.2-96.7).

CONCLUSION: The 60-minute PRMCC test is noninvasive and feasible in children with a high negative predictive value for PCD. It may be a helpful adjunctive test to rule out PCD when clinical suspicion remains after guideline recommended first-line clinical testing.
