Is endometrial infection with Candida albicans a cause of recurrent vaginal thrush?

OBJECTIVE--It was hypothesised that the endometrium might act as a reservoir for candida, thus infecting the vagina as the endometrium is shed during menstruation. DESIGN--A prospective study of women with recurrent vulvo-vaginal candidiasis. The endometrium was sampled and cultured for candida species. SETTING--Central London STD clinic. SUBJECTS--26 women were enrolled, of whom 20 completed the study. RESULTS--One patient had a positive endometrial culture for candida species, the isolate being Candida krusei. CONCLUSIONS--The endometrium is not a common resevoir for candida species and therefore, infection at this site is an unlikely cause of recurrent vaginal candidiasis.
