Prevalence of polycystic kidney disease in Persian and Persian related cats in France.
The prevalence of polycystic kidney disease (PKD) has been estimated in the USA, Australia, UK, and Germany, but no data are available to date in France. The purpose of this study was to determine prevalence of PKD in Persian and Persian related breeds of cats in France. Medical records of all healthy cats presented for ultrasonographic screening of PKD between December 2000 and April 2002 were analysed from two centres (ENVL and ENVA). Cats were classified as positive when at least one anechoic cavity was found in at least one kidney. Prevalence of PKD was compared between the two screening centres, between different breeds evaluated, and between male and female using Chi-square test. A total of 310 cats were examined, including 92 at ENVL (57 Persians, 22 Exotic Shorthairs, 7 Chartreux, 4 Norwegian Forest Cats, and 2 Abyssins) and 218 at ENVA (163 Persians, 42 Exotic Shorthairs, 4 Chartreux, 4 British Shorthairs, 2 American Whirehairs, 2 Norwegian Forest Cats, and 1 American Shorthair). Prevalence of PKD was 41.8% in Persian cats and 39.1% in Exotic Shorthair. No PKD was detected in cats from other breeds. There was no significant difference between prevalence of PKD found in ENVL and ENVA, between prevalence of PKD in Persians and in Exotic Shorthairs, and prevalence of PKD in male and in female. Prevalence of PKD in Persians and Exotic Shorthair cats in France is currently high but is similar to prevalence in other parts of the world. Selection based on ultrasonographic detection of cysts should decrease prevalence of PKD in the future.
