The effect of successful renal transplantation on hormonal status of female recipients

The pituitary, thyroid, and ovarian hormone levels were measured by enzyme and fluorescence polarization immunoassays in 18 women with successful renal transplants (recipients): 10 menstruating, mean age 34.7 years, mean time after transplantation (Tx) 112.00 months, mean SCr 130.60 mumol/L; and 8 menopausal, mean age 52.7 years, mean time after Tx 61.00 months, and mean SCr 119.00 mumol/L. Five women of the menstruating group conceived 7 times and gave birth to 4 healthy infants. The findings were compared to 30 age-matched healthy subjects (controls) and to 13 women under chronic hemodialysis (hemodialyzed patients): 2 menstruating, 24 and 36 years old, and 11 menopausal, mean age 59.4 years. Serum prolactin (PRL) showed a highly significant increase in hemodialyzed patients (p less than .0001) compared to controls. In recipients, PRL levels were significantly lower than in hemodialyzed patients, but higher than in controls (p less than .0001). LH and FSH were elevated in menstruating hemodialyzed patients (p less than .0001, p less than .02, respectively) and significantly high in menopausal hemodialyzed patients (p less than .02, p less than .01, respectively). In menstruating recipients, LH was also highly elevated (p less than .001), while FSH showed no significant difference from controls. In menopausal recipients the increase of LH was less prominent (p less than .02) but FSH was highly increased (p less than .001). T3, T4, and FTI were absolutely normal in recipients, while they were significantly lower than normal (p less than .0001) in hemodialyzed patients. Estradiol showed no significant difference in both groups of recipients, as well as in menopausal hemodialyzed patients.(ABSTRACT TRUNCATED AT 250 WORDS)
