Vaginal heat shock protein expression in symptom-free women with a history of recurrent vulvovaginitis.
OBJECTIVES: The cause of recurrent vulvovaginitis remains unexplained in most cases. Heat shock protein synthesis is induced under conditions of stress; its presence in vaginal samples from women who were between episodes of recurrent vulvovaginitis thus might reflect a persistent perturbation in the local milieu. Study Design: We undertook an evaluation by means of enzyme-linked immunosorbent assay of 60-kd heat shock protein and inducible 70-kd heat shock protein expressions in vaginal wash samples from 24 symptom-free women with a history of recurrent vulvovaginitis and 19 matched control subjects. The samples were also tested for Candida albicans, Chlamydia trachomatis, Ureaplasma urealyticum, Mycoplasma hominis, and human papillomavirus by polymerase chain reaction; for bacterial vaginosis by clinical and microbiologic evaluation; and for interleukin 10, interleukin 1, interleukin 8, RANTES, and eotaxin by enzyme-linked immunosorbent assay. RESULTS: The presence of 60-kd heat shock protein was detected in 11 women with recurrent vulvovaginitis (45.8%) and 1 control subject (5.3%, P =.005). Similarly, 70-kd heat shock protein was present in 8 patients with recurrent vulvovaginitis (33.3%) and no control subjects (P =.005). The presence of 60-kd heat shock protein and the presence of 70-kd heat shock protein were correlated with each other (P =.02), as were both 60-kd heat shock protein (P =.006) and 70-kd heat shock protein (P =.01) correlated with IL-10. There was no relation between the presence of 60-kd heat shock protein or 70-kd heat shock protein and detection of IL-1, IL-8, or any microorganism. CONCLUSION: The expression of heat shock proteins and IL-10 in the vaginas of women with a history of recurrent vulvovaginitis but not in the vaginas of control subjects suggests the existence of differences in the vaginal milieu between the 2 groups, even when both are without vaginal symptoms.[1]References
