Effect of hormone replacement therapy on epidermal barrier lipids.

چکیده
Current evidence of the effect of hormone replacement therapy (HRT) on skin lipids, of postmenopausal women is scanty and indirect. Here, we report the ultrastructural differences in epidermal lipids between postmenopausal subjects who were and were not on HRT and a comparison is made with younger subjects. Biopsies were obtained from arms and legs, in a blinded, no-treatment, study conducted on postmenopausal subjects who were and were not on HRT and younger subjects. The ultrastructure of skin lipids and the lipid coverage of underlying corneocytes were compared for biopsies obtained from different subjects. Qualitative assessment as well as quantitative estimation of lipid-covered regions of corneocytes shows that skin lipids do not cover corneocytes effectively in postmenopausal women who are not on HRT. However, women who are on HRT show significantly improved lipid coverage of corneocytes, which is comparable with the younger subjects. This implies that HRT should improve the lipid coverage and skin condition of postmenopausal women.

OBJECTIVES We studied the effect of hormonal treatment on skin ageing in menopausal women. METHODS Twenty-four patients (45-68 years; mean age, 54.9 years) without hormone treatment for at least 6 months were included.

متن کاملEffects of aerobic exercise on ectopic lipids in patients with growth hormone deficiency before and after growth hormone replacement therapy
Growth hormone replacement therapy (GHRT) increases exercise capacity and insulin resistance while it decreases fat mass in growth hormone-deficient patients (GHD). Ectopic lipids (intramyocellular (IMCL) and intrahepatocellular lipids (IHCL) are related to insulin resistance. The effect of GHRT on ectopic lipids is unknown. It is hypothesized that exercise-induced utilization of ectopic lipids...

متن کاملEffects of hormone replacement therapy on lipoprotein(a) and lipids in postmenopausal women.
High concentrations of lipoprotein(a) [Lp(a)], an independent risk factor for atherosclerosis, cannot be managed by the usual lipid-lowering agents. It has been suggested that Lp(a) levels are related to female sex hormones. Estrogen replacement therapy makes the lipid profiles favorable for delaying atherosclerosis in postmenopausal women. The effects of the combination therapy of estrogen and...
