Another advantage is that, unlike creatinine, blood levels of cystatin C are less influenced by age, gender, race, or lean muscle mass,...

We examined the effects of L-thyroxin on level of prolactin (PRL), CRP (C-reactive protein) and insulin in premenopausal women with subclinical hypothyreoidism (SH).The study included 21 women ages 41.3±3.5 years with SH (TSH>mIU/ml with normal level of T3 and T4).Laboratory evaluation included basal hormone (serum free T3, free T4, TSH, PRL, insulin, cortisol, ACTH, GH, FSH, LH, E2, thyroid antibodies and TGL), level of C...
