Current trends in hormone replacement therapy: perceptions and usage

OBJECTIVE: To determine whether physicians' confidence in the use of hormone replacement therapy (HRT) for climacteric symptoms has been affected by the negative media interpretation of data from landmark studies investigating HRT usage such as the Women's Health Initiative (WHI) study. METHODS: A structured questionnaire was completed via the internet by European and US gynecologists, obstetrician/gynecologists and general practitioners - all experienced in treating women with climacteric symptoms. RESULTS: Six hundred physicians completed the survey in six countries. Overall, 98% agreed that the menopause significantly affects quality of life and 97% considered that the majority/all of their patients experienced positive benefits from HRT. Most physicians (90%) believed the benefits of HRT outweigh the risks in suitable patients, and 92% would prescribe HRT for themselves/spouse/family. For treatment of atrophic vaginitis, 86% agreed that local estrogen was the most effective course of action. While 82% of participants were aware of the latest recommendations on low-dose HRT, and estrogen dose in particular, 67% cited lowering the progestogen dose as important. With regard to the recent negative media coverage on HRT, 78% of physicians felt this was unjustified. CONCLUSIONS: These results provide reassurance that health-care professionals in Europe and the US, experienced in treating women with climacteric symptoms, have not lost confidence in HRT. Despite a consensus on the importance of lowering the dose of HRT and a focus on estrogen, there remains a need to heighten prescribers' awareness on the pivotal role that a lower progestogen dose plays in optimizing the risk-benefit profile.

Prevention of postmenopausal bone loss using tibolone or conventional peroral or transdermal hormone replacement therapy with 17beta-estradiol and dydrogesterone

Postmenopausal bone loss can be prevented by continuous or intermittent estradiol (E2) administration. Concomitant progestogen therapy is mandatory in nonhysterectomized women to curtail the risk of endometrial hyperplasia or cancer. However, the recurrence of vaginal bleeding induced by sequential progestogen therapy in addition to continuous estrogen administration is one of the reasons for noncompliance to hormone replacement therapy (HRT). Tibolone, a synthetic steroid with simultaneous weak estrogenic, androgenic, and progestational activity, which does not stimulate endometrial proliferation, has recently been proposed for the treatment of climacteric symptoms. To compare the efficacy of conventional oral and transdermal HRT with that of tibolone in the prevention of postmenopausal bone loss, 140 postmenopausal women (age, 52 +/- 0.6 years; median duration of menopause, 3 years) were enrolled in an open 2-year study. Volunteers had been offered a choice between HRT and no therapy (control group, CO). Patients selecting HRT were randomly allocated to one of the following three treatment groups: TIB, tibolone, 2.5 mg/day continuously, orally; PO, peroral E2, 2 mg/day continuously, plus sequential oral dydrogesterone (DYD), 10 mg/day, for 14 days of a 28-day cycle; TTS, transdermal E2 by patch releasing 50 microg/day, plus DYD as above. Bone densitometry of the lumbar spine, upper femur, and whole body was performed using dual-energy X-ray absorptiometry at baseline, and then 6, 12, 18, and 24 months after initiation of therapy. One hundred and fifteen women (82%) completed the 2 years of the study. The dropout rate was similar in each group. Over 2 years, bone preservation was observed in all three treatment groups as compared with controls, without significant differences among treatment regimens. In conclusion, tibolone can be regarded as an alternative to conventional HRT to prevent postmenopausal bone loss.

Ultra-low dose - new approaches in menopausal hormone therapy.

Despite increasing life expectancy, the age of onset of natural menopause has not significantly changed in recent decades. Thus, women spend about one-third of their lives in an estrogen-deficient state if untreated. There is a need for appropriate treatment of acute symptoms and prevention of the sequelae of chronic estrogen deficiency. International guidelines call for the use of the lowest effective hormone dosage for vasomotor symptom relief, the major indication for menopausal hormone therapy (MHT). In 2011, an oral continuous combined ultra-low-dose MHT was approved in Switzerland. This publication was elaborated by eight national menopause specialists and intends to review the advantages and disadvantages of ultra-low-dose MHT after the first years of its general use in Switzerland. It concludes that, for many women, ultra-low-dose MHT may be sufficient to decrease vasomotor symptoms, but not necessarily to guarantee fracture prevention.

Efficacy and safety of non-hormonal remedies for vaginal dryness: open, prospective, randomized trial

OBJECTIVES To prove non-inferiority of the first non-hormonal vaginal cream in Germany, Vagisan(®) Moisturising Cream (CREAM), compared to a non-hormonal vaginal gel (GEL) for vulvovaginal atrophy (VVA) symptom relief. METHOD This was a 12-week multicenter, open-label, prospective, randomized, two-period, cross-over phase-III trial. The primary endpoint was the cumulative VVA subjective symptom score of the respective treatment period. Secondary endpoints were assessment of single VVA subjective and objective symptoms, VVA objective symptom score, vaginal pH, safety parameters, overall assessment of efficacy, tolerability and evaluation of product properties. In total, 117 women were randomly allocated to either one of the two treatments, each administered for 4 weeks; 92 women were included in the per-protocol analysis (primary analysis). The main outcome measure was cumulative VVA subjective symptom score. RESULTS Regarding VVA symptom relief, results confirmed non-inferiority of CREAM compared to GEL and even indicated superiority of CREAM. Frequency and intensity of subjective symptoms and objective findings were clearly reduced, with CREAM showing better results compared to GEL. Mean VVA objective symptom score significantly decreased; improvement was significantly greater with CREAM. Vaginal pH decreased only following CREAM treatment. Tolerability was superior for CREAM: burning and itching, mostly rated as mild, occurred markedly less often with CREAM than with GEL. Overall satisfaction with treatment efficacy, tolerability and most product properties were rated significantly superior for CREAM. CONCLUSIONS Subjective and objective VVA symptoms were reliably and safely reduced by both non-hormonal topical products. However, efficacy and tolerability of CREAM were shown to be superior to GEL.
