Here, we perform a comprehensive analysis on the effects of different thyroid abnormalities on sexual and reproductive-related hormones in both men and women in different age groups. Method: A comprehensive analysis was performed on 15,043 subjects within the reproductive age (15 - 49 years). They were tested for thyroid markers (TSH, FT4, anti-TPO, anti-Tg) and 13 reproductive hormones in Vibrant America Clinical Laboratory between March 2016 to July 2018. The alterations of each reproductive hormone in hypothyroidism, hyperthyroidism, anti-TPO+ anti-Tg+ groups were evaluated. Results: A total of 10,626 women was tested. Women with hypothyroidism had elevated cortisol and low SHBG and DHEA-S. Women with hyperthyroidism showed elevated total testosterone and SHBG. Women seropositive for anti-TPO had elevated total testosterone and low cortisol. Women seropositive for anti-Tg had low parathyroid hormones. Similarly, a total of 4417 men was tested. Men with hypothyroidism had low IGF-I. Similarly, men with hyperthyroidism had low DHEA-S, but elevated estradiol, FSH, LH and prolactin. Men seropositive for anti-TPO had elevated SHBG and low progesterone. Men seropositive for anti-Tg had elevated progesterone. The reproductive and related hormone levels of age group 36 - 49 showed the most variations. Conclusion: Our results clearly show that individuals with different thyroid alterations have different effects on reproductive health, especially in the age group 36 - 49. Hence, routine testing and follow-up checkups on reproductive system would be beneficial for individuals in the age group 36 - 49 with thyroid disorders.展开更多

A cascade autoantibody testing is usually performed by employing antinuclear antibodies (ANA) test as a first screening test and the other tests as second level determinations. Here, we present that supplementing extractable nuclear antigens (ENA) tests to the ANA test may capture more autoimmunity and provide critical medical information at an early stage. In this study, we?evaluated the clinical significance of a multiplex ANA + ENA panel. Methods: A cohort of 110 subjects, identified as ANA negative but ENA positive, were followed up for two years. The detection of their ANA and anti-ENA autoantibodies was assessed with a multiplex ANA + ENA panel at Vibrant America Clinical Laboratory. Results: During two years of multi-visit follow-up, 23 out of 110 subjects (20.9%) were found to become ANA positive within an average of 385 (±144) days. Histone (50/110, 45.5%) and Chromatin (25/110, 22.7%) antibodies were the most frequently found antibodies at their first visits. The subjects who were positive for RNP (5/8, 62.5%) and SSA (Ro) (10/22, 45.5%) have the highest ratio of conversion to positive ANA. No significant correlation was observed between the conversion frequency and the number of anti-ENA antibodies being carried. Conclusion: This study, which followed up on the subjects who had disparate ANA and ENA test results, showed that anti-ENA antibodies may exist years earlier than ANA. Combining ENA tests with ANA screening may reduce false negatives and improve sensitivity.展开更多
