title: Raised circulating levels of interleukin-6 in women with an intrauterine contraceptive device.
abstract: The aim of this study was to determine whether the presence of an intrauterine contraceptive device (IUCD) causes a systemic elevation of interleukin-6 (IL-6). The control group comprised 29 women with normal cycles and who were not using any form of contraception and the study group comprised 74 women who had had an IUCD in place for 10-24 months. Of these, 45 had intermenstrual bleeding. Systemic IL-6 was undetectable (minimum detection limit of the assay is 5 pg/ml) in the control but was raised in 20% of the women fitted with an IUCD (p < 0.01). There was no difference between IL-6 levels in IUCD users who had intermenstrual bleeding and those who did not. These results suggest that the effects of chronic IUCD usage may not be limited to the endometrium.
