Background/Aims: In women with chronic kidney disease (CKD) fertility abnormalities occur frequently. Anti-Müllerian hormone (AMH) inhibits excessive recruitment of primordial follicles. The aim of the study was to evaluate the serum AMH concentration in women on hemodialysis and after kidney transplantation (KTx). Methods: 46 hemodialysed women and 14 with CKD about to undergo kidney transplantation were enrolled into the study. The control group consisted of 40 healthy women. In all subjects serum concentration of AMH was determined (in chronic hemodialysis women and in control group once, and in women after KTx immediately before surgery, and 3 times after the transplantation). Results: Serum AMH concentration in hemodialysed women and in the control group did not differ significantly, while in hemodialysed women with regular menstrual cycles it was significantly lower than in the control group: 2.20 (1.08-3.55ng/ml) and 3.30 (1.80-6.10ng/ml) respectively, (p=0.02). In the KTx group, a significant decrease in serum AMH concentration was found from 3.30ng/ml (2.20-6.50ng/ml) at baseline to 1.90ng/ml (1.30-2.40ng/ml) at 6 months after KTx (p=0.007). Conclusions: 1. Significantly lower serum AMH concentration was found in the regularly menstruating CKD women on hemodialysis in comparison with the healthy controls. 2. Serum AMH decreased significantly after successful KTx.
Experimental data have shown increased plasma levels of marinobufagenin in kidney failure. In this case-controlled retrospective analysis, we evaluated plasma marinobufagenin immunoreactivity in hemodialysis patients compared with subjects with normal kidney function. Sixty-eight adult hemodialysis patients with chronic kidney disease (34 females and 34 males) as well as 68 age-, gender-, and blood pressure-matched subjects without chronic kidney disease were enrolled. Patients on stable hemodialysis regimen for at least 3 mo before the study were included. Exclusion criteria were: age <18 yr, severe liver or heart insufficiency, and overhydration. Subjects without chronic kidney disease must have had an estimated glomerular filtration rate ≥60 ml·min·1.72 m according to the Modification of Diet in Renal Disease formula. Plasma marinobufagenin immunoreactivity was significantly ( P < 0.001) higher in hemodialysis patients (1.66 ± 1.13 nmol/l) compared with subjects with normal kidney function (0.46 ± 0.23). In hemodialysis patients, plasma marinobufagenin immunoreactivity was higher in men compared with women. A significant positive correlation has been found between plasma marinobufagenin immunoreactivity and serum NT-proBNP, NT-proANP, or aldosterone concentrations in all analyzed subjects. In hemodialyzed patients with plasma marinobufagenin immunoreactivity above median value 5-yr, all-cause mortality was higher compared with those with plasma marinobufagenin concentration below median. We have shown that plasma marinobufagenin immunoreactivity is increased in patients with end-stage kidney failure treated with hemodialysis parallel to the increase in serum NT-proBNP, NT-proANP, and aldosterone concentrations. Higher marinobufagenin immunoreactivity has been associated with worse survival in hemodialyzed patients.
Successful kidney transplantation leads to the normalization of serum concentrations of hormones linked to fertility disorders in women with chronic kidney disease. < p > < /p >.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
