The research for levels of thyroid hormone in patients with Sheehan′s syndrome / 国际检验医学杂志

ABSTRACT

Objective To research the levels of thyroid hormone in patients with Sheehan′s syndrome .Methods The difference of thyroid‐stimulating hormone(TSH) or free triiodothyronine(fT3 ) or free thyroxine(fT4 ) levels was compared between 100 pa‐tients with sheehan′s syndrome and 100 cases of female healthy controls included in this study .The difference for TSH or fT3 or fT4 levels was compared between before and after treatment in Sheehan′s syndrome patients .The difference of TSH or fT3 or fT4 levels was compared when time from a large bleeding to disease onset below 1 year ,1‐5 years and over 5 years respectively in Shee‐han′s syndrome patients .Results The difference of TSH or fT3 or fT4 levels between patients with Sheehan′s syndrome and female healthy controls had obvious statistical significance .TSH1 .60(0 .79 -2 .86)mU/L versus 3 .08(1 .97 -5 .08)mU/L ,fT32 .09 (1 .44-3 .69)pmol/L versus 4 .86(4 .49-5 .40)pmol/L ,fT48 .01(3 .45 -12 .64)pmol/L versus 14 .56(13 .63 -16 .11)pmol/L (P<0 .001 for comparisons respectively) .The difference of TSH or fT3 or fT4 levels between before and after treatment had obvi‐ous statistical significance .TSH1 .60(0 .79-2 .86)mU/L versus 1 .16(0 .57-2 .11)mU/L ,fT32 .09(1 .44-3 .69)pmol/L versus 3 .27(2 .38-4 .11)pmol/L ,fT48 .01(3 .45 -12 .64)pmol/L versus 14 .32(10 .48 -15 .92)pmol/L(P<0 .05 for comparisons re‐spectively) .Time from a large bleeding to disease onset were below 1 year ,1-5 years and over 5 years ,TSH levels were respective‐ly 2 .85(2 .21-3 .51)、1 .82(1 .24-2 .98) and 1 .52(0 .65-2 .64)mU/L(P<0 .05 for comparisons) .The fT3 levels were respective‐ly 3 .74(2 .24-4 .45) ,2 .54(1 .87-3 .32) and 1 .89(1 .13-3 .11)pmol/L(P<0 .05 for comparisons) .The fT4 levels were respec‐tively 12 .21(10 .45-14 .32) ,8 .52(5 .13-12 .34) and 7 .85(3 .12 -10 .12)pmol/L(P<0 .05 for comparisons) .Conclusion TSH could serve as an identifiable index for sheehan′s syndrome and primary hypothyroidism .The time from a large bleeding to the dis‐ease onset is longer ,the anterior pituitary function is more serious .Thyroid hormone should be monitored regularly in order to pre‐vent the happening of hyperthyroidism during the process of the treatment .For postpartum hemorrhage patients ,thyroid hormone should be early detected and combine with the clinical manifestations .They should early diagnose and timely treat in order to pre‐vent the sheehan′s syndrome and its crisis .
