The aim of this study was to investigate the prevalence and character of autoimmune derangements in women with reproductive failure. A total of 108 females (age range 17-43, mean 27.5 years), including 16 with primary menstrual cycle disturbances and polycystic ovaries (PCO), 20 with polycystic ovary syndrome (PCOS), 38 with endometriosis (E), and 34 with chronic anovulation, luteal phase insufficiency, subfertility or unexplained infertility (INF) were investigated. A control group of 392 women was formed from an unselected population sample (age range 17-43, mean 31.0 years). All sera were tested by indirect immunofluorescence method to assess common autoantibodies: nuclear (ANA), smooth muscle (SMA), parietal cell (PCA), thyroid microsomal (TMA), reticulin (ARA), mitochondrial (AMA) and liver/kidney microsomal autoantibodies (LKMA). Enzyme-linked immunosorbent assay was used to detect antibodies against beta2-glycoprotein I (anti-beta 2GPI) and carbonic anhydrase (anti-CA). Our results showed that 40.7% of patients' sera and 14.8% of control sera contained one or more common autoantibodies, ANA and SMA were most frequently detected (difference between two groups P<0.005). Anti-beta 2GPI were found in eight cases (7.4%), including two patients with INF but without other autoantibodies. Anti-CA were revealed in nine cases (8.3%) including patients' PCOS, E and INF. A comparison of patients' clinical data with antibody assay results did not reveal any significant associations. Our results indicate a high prevalence of autoimmune reactions in women with reproductive failure due to the most common causes PCO, PCOS and E as well as in unexplained infertility. This might reflect the propensity to develop autoimmune reactions in such patients, including pathogenic autoimmune reactions to specific target antigens.

One hundred and forty patients with Graves' disease [32 new patients, 54 treated with propylthiouracil (PTU) for a mean of 27.2 months and 54 treated with methimazole (MMI) for a mean of 48.6 months] were tested for anti-thyroid microsomal antibody (AMA), anti-thyroglobulin antibody (ATA), thyroid binding inhibitory immunoglobulin (TBII), and the non organ specific autoantibodies [i.e., anti-nuclear antibody (ANA), anti-double stranded DNA antibody (anti-dsDNA Ab), anti-cardiolipin antibody (aCL Ab) and anti-beta2-glycoprotein I antibody (IgG beta2GPI)]. Treatment with MMI or PTU produced a significant difference in IgG aCL Ab production but not in ANA, dsDNA Ab, IgM aCL or IgG beta2GPI. For those treated with MMI but not those treated with PTU, ANA and anti-dsDNA Ab were positively correlated. IgG and IgM aCL Ab were positively correlated overall and for those on MMI but not PTU treatment. No significant difference was found for any of the four non organ specific antibodies in AMA positive or negative patients but there was a significant difference in IgG aCL positivity rates for ATA positive and negative patients. On the other hand, ANA negative patients were significantly more likely to have higher TBII values. These results suggest that the appearance of the non organ specific autoantibodies is probably largely a coincidental effect of polyclonal activation - except, perhaps, for IgG aCL, which may be related to treatment.
