Gabapentin vs. low-dose transdermal estradiol for treating post-menopausal women with moderate to very severe hot flushes.

BACKGROUND: Gabapentin (GPT), a widely used drug in neurology, has been proposed as a non-hormonal option for the management of hot flushes in menopausal women with contraindications for estrogen therapy. OBJECTIVE: To compare GPT versus low-dose transdermal estradiol (E(2)) for treating post-menopausal women with moderate to very severe hot flushes. METHODS: A total of 45 post-menopausal women with moderate to very severe hot flushes were prospectively and single-blinded randomised to receive oral GPT 600 mg/night or transdermal 25 microg/day E(2) per week. Hot flush intensity and frequency were assessed with the Menopause Rating Scale and a numeric scale respectively at baseline and at 1, 4 and 8 weeks. Side effects were also assessed. RESULTS: Hot flush intensity and frequency significantly decreased for both groups at 1, 4 and 8 weeks of treatment as compared to baseline; however, this decrease was statistically more evident for the E(2) group. Although the percentage of hot flush intensity and frequency reduction at the end of the treatment was higher for E2, this was not statistically significant (68.2% vs. 60.6% for intensity and 70.1% vs. 58.9% for frequency, respectively, p > 0.05, NS). Encountered side effects included: drowsiness, dizziness, fatigue (GPT group) and mastodynia, vaginal spotting and a local allergic reaction (E(2) group). Compliance to treatment was 95.6% (GPT group) as compared to 90.9% for the E(2) group. CONCLUSION: Despite statistical significant differences, from a clinical point of view oral GPT 600 mg was as effective as low-dose transdermal E(2) in controlling moderate to severe hot flushes in post-menopausal women, and should be recommended as an alternative option in those with contraindications to estrogen therapy. More research is warranted in this regard.

Risk factors related to the presence and severity of hot flushes in mid-aged Ecuadorian women.

BACKGROUND: Several studies drawn from the Ecuadorian population have previously reported that more than half of mid-aged women present hot flushes, which can impair their quality of life. However up-to-date risk factors for their presence and severity have not been assessed. OBJECTIVE: To assess hot flush frequency and intensity and related risk factors among middle-aged Ecuadorian women. METHODS: In this cross-sectional study, 1154 healthy women aged 40-59 years, visiting healthcare centers of eight main cities of Ecuador with more than 100,000 inhabitants, were assessed with the first item of the Menopause Rating Scale (MRS) and a questionnaire containing female and partner socio-demographic data. RESULTS: Mean age of the entire sample was 48.8+/-5.6 years (median 48), a 48.7% had 12 or less years of schooling, 52.8% were postmenopausal, 43.6% lived at high altitude, 56.8% were married and 10% were on hormonal therapy (HT). Hot flushes accounted for 56% (n=646) of the whole sample, of which 29.1% and 9.1% were respectively graded as severe and very severe. Logistic regression determined that female sedentarism (OR: 2.42, CI 95% [1.63-3.59]), accessing a free healthcare system (OR: 1.96, CI 95% [1.30-2.96]), living at high altitude (OR: 1.82, CI 95% [1.14-2.90]) and having a partner abusing alcohol (OR: 1.92, CI 95% [1.09-3.35]) were significant risk factors related to the presence of hot flushes. The regression model also determined that among women with hot flushes (n=646), sedentarism (OR: 1.73, CI 95% [1.14-2.62]) and having a partner with erectile dysfunction (OR: 2.57, CI 95% [1.44-4.59]) were significant risk factors related to severe/very severe hot flushes whereas married status (OR: 0.53, CI 95% [0.32-0.86]), living at high altitude (OR: 0.46, CI 95% [0.26-0.78]) and partner healthiness (OR: 0.59, CI 95% [0.36-0.95]) were not. CONCLUSION: To the best of our knowledge this is the first and largest study assessing hot flushes in a mid-aged Ecuadorian population. We found that the presence and severity were not significantly related to age and hormonal status yet to other individual female/male characteristics and the demography of the studied population.
