Polymorphisms in Estrogen Synthesis Genes and Symptom Clusters During the Menopausal Transition and Early Postmenopause: Observations From the Seattle Midlife Women's Health Study.

ABSTRACT: During the menopausal transition and early postmenopause, participants in the Seattle Midlife Women's Health Study (SMWHS) experienced one of the three symptom severity clusters identified through latent class analysis: severe hot flashes with moderate sleep, mood, cognitive, and pain symptoms (high-severity hot flash); low-severity hot flashes with moderate levels of all other symptom groups (moderate severity); and low levels of all symptom groups (low severity). In an effort to determine whether gene polymorphisms were associated with these symptom severity classes, we tested associations between gene polymorphisms in the estrogen synthesis pathways (cytochrome P450 19 [CYP 19] and 17 beta hydroxysteroid dehydrogenase [ 17HSDB1]) and the three symptom severity clusters. SMWHS participants ( N = 137) recorded symptoms monthly in diaries and provided buccal smears for genotyping. Multilevel latent class analysis with multinomial regression was used to determine associations between gene polymorphisms and symptom severity clusters. Only the 17HSDB1 polymorphisms ( rs615942 and rs592389) were associated significantly with the high-severity hot flash cluster versus the low-severity symptom cluster. None of the polymorphisms was associated with the moderate-severity cluster versus the low-severity symptom cluster. Findings of associations of the 17HSDB1 polymorphisms with the high-severity hot flash symptom cluster are consistent with those of an association between 17HSDB1 polymorphisms and hot flashes in the Study of Women and Health Across the Nation population and our previous findings of associations between these polymorphisms with greater estrone levels.

Project description:ObjectiveThe aim of this study was to assess vasomotor and other menopausal symptoms before starting estrogens or placebo, 1 year later, again at trial closure, and after stopping estrogens or placebo. The role of baseline symptoms and age was examined, as was the frequency and determinants of hormone use and symptom management strategies after discontinuing conjugated equine estrogens (CEE) or placebo.MethodsIntent-to-treat analyses of 10,739 postmenopausal women before and 1 year after randomization to CEE or placebo at 40 clinical centers and a cohort analysis of participants (n = 3,496) who continued taking assigned study pills up to trial closure and completed symptom surveys shortly before (mean, 7.4 +/- 1.1 y from baseline) and after (mean, 306 +/- 55 d after trial closure) stopping pills were performed. Generalized linear regression modeled vasomotor symptoms, vaginal dryness, breast tenderness, pain/stiffness, and mood swings as a function of treatment assignment and baseline symptoms, before and after stopping study pills.ResultsApproximately one third of participants reported at least one moderate to severe symptom at baseline. Fewer symptoms were reported with increasing age, except joint pain/stiffness, which was similar among age groups. At 1 year, hot flashes, night sweats, and vaginal dryness were reduced by CEE, whereas breast tenderness was increased. Breast tenderness was also significantly higher in the CEE group at trial closure. After stopping, vasomotor symptoms were reported by significantly more women who had reported symptoms at baseline, compared with those who had not, and by significantly more participants assigned to CEE (9.8%) versus placebo (3.2%); however, among women with no moderate or severe symptoms at baseline, more than five times as many reported hot flashes after stopping CEE (7.2%) versus placebo (1.5%).ConclusionsCEE significantly reduced vasomotor symptoms and vaginal dryness in women with baseline symptoms but increased breast tenderness. The likelihood of experiencing symptoms was significantly higher after stopping CEE than placebo regardless of baseline symptom status. These potential effects should be considered before initiating CEE to relieve menopausal symptoms.

Project description:ObjectiveTo characterise symptoms experienced by women during the transition into natural menopause, to classify women into distinct symptom profiles or trajectories, and to relate these profiles to sociodemographic factors and health behaviours.DesignNationally representative cohort study.SettingEngland, Scotland, and Wales.Participants695 women followed-up since birth in 1946 and annually from age 47 to 54 who experienced natural menopause and reported on 20 common health symptoms.Main outcome measureLongitudinal profiles for reported bothersome symptoms.ResultsOf 20 individual symptoms, 18 formed into four stable symptom groups: psychological, somatic, vasomotor, and sexual discomfort. Using latent class analyses, all except the somatic group of symptoms showed a clear relation with the timing of menopause for some women. A small proportion of women (10%, n=63) had a severe psychological symptom profile that peaked at or in the year after menopause. For vasomotor symptoms, 14% of women (n=83) had the early severe profile that also peaked around early postmenopause and then declined noticeably; 11% (n=67) had the late severe profile of bothersome symptoms that increased rapidly in perimenopause and remained high for four years or more after menopause. Women were less likely to have a profile for severe vasomotor symptoms if they were from a non-manual social class (odds ratio 0.79, 95% confidence interval 0.57 to 1.01) or had degree level qualifications (0.37, 0.18 to 0.77). The 14% of women (n=85) who had the late severe profile for sexual discomfort showed a similar increase in symptoms until menopause, with symptoms persisting after menopause. Married women were more likely to have the late severe or late moderate profile than women of other marital status (2.40, 1.30 to 4.41). Four profiles each were identified for somatic symptoms (mild, moderate, severe, and very severe), although these did not vary by chronological age or age at menopause.ConclusionProfiles for psychological, vasomotor, and sexual discomfort symptoms relative to age at menopause could help health professionals to tailor their advice for women with natural menopause.
