RT Journal Article SR Electronic T1 High prevalence of primary ciliary dyskinesia in a British Asian population JF Archives of Disease in Childhood JO Arch Dis Child FD BMJ Publishing Group Ltd and Royal College of Paediatrics and Child Health SP 51 OP 52 DO 10.1136/adc.2009.158493 VO 95 IS 1 A1 O’Callaghan, C A1 Chetcuti, P A1 Moya, E YR 2010 UL http://adc.bmj.com/content/95/1/51.abstract AB Determining the prevalence of primary ciliary dyskinesia (PCD) in different populations has proved difficult, with estimates varying between one in 4000 to one in 40 000. The aim of this study was to determine the incidence of PCD in a well-defined highly consanguineous Asian population in the UK. Over a 15-year period all patients suspected of having PCD in the Asian population of Bradford, UK, were tested by measurement of ciliary beat pattern, frequency and electron microscopy. The prevalence of PCD in the population studied was one in 2265. 52% of the patients' parents were first cousins. All patients had a history of chronic cough and nasal symptoms from the first year of life. 73% had a history of neonatal respiratory distress. Clinical suspicion of PCD should be high in populations in which it is possible that high levels of consanguinity may result in an increase in those with PCD. In these communities the combination of chronic cough and nasal symptoms should prompt early diagnostic testing.
