Efficacy on menopausal neurovegetative symptoms and some plasma lipids blood levels of an herbal product containing isoflavones and other plant extracts.

OBJECTIVES: To assess the efficacy of a product containing isoflavones and other plant extracts (BIO) on whole menopausal symptomatology and plasma lipids profile. METHODS: Multicentre, randomized, double blind, placebo controlled clinical investigation on 125 menopausal women randomly assigned to two groups treated for 6 months with placebo or one tablet daily of an herbal product containing 72 mg/dose of isoflavones of different plants origin and other plant extracts (BIO). Primary end-point: Kupperman Menopause Index (KI) variations; secondary end-point: activity on plasma lipids profile and clinical global impression (CGI) on efficacy and tolerability by investigators and patients. The usual parametric test (paired Student t test) was performed to evaluate the significance. In case of non-applicability of parametric tests, the non-parametric Mann-Whitney U test was used. The differences where considered significant at p<0.05 level. RESULTS: At the end of treatment in both groups KI showed a significant decrease (p<0.001). However, in the BIO group the KI reduction was significantly higher (p=0.0265) than in the placebo group after 4 and 6 months of treatment. In the BIO treated patients the LDL cholesterol showed a borderline but not significant reduction compared to placebo (p=0.0608) and triglyceride (TG) a significant (p=0.0151) decrease compared to placebo. The investigator's and patient's CGI on BIO group where superior as compared to placebo. Clinical tolerability was good in booth groups. CONCLUSION: On the basis of positive effects on KI and lipids profile as well as of good clinical tolerability, BIO can be considered one of the possible alternative therapy for conventional HRT.

The effect of tibolone versus continuous combined norethisterone acetate and oestradiol on memory, libido and mood of postmenopausal women: a pilot study.

OBJECTIVE: Several studies have shown a positive effect of oestrogen on memory, mood and well-being but these data are controversial and focus particularly on the effect of oestrogen alone. In this pilot study we have investigated the effect of a continuous combination of norethisterone acetate 1 mg and oestradiol valerate 2 mg (Kliogest) versus tibolone (Livial) on memory, sexuality and mood. METHODS: Twenty-two postmenopausal women, age range 51-57, were randomised to a 6 months single blind interventional study treatment with either continuous combined oestradiol plus norethisterone acetate, or tibolone. Computerised psychological test of memory, mood and libido were administered both before and at the end of the 6 months treatment. RESULTS: Fourteen patients completed the study; eight on Livial and six on Kliogest. Recognition memory was improved by Kliogest but not by Livial (P<0.05) while either drug equally improved both the reaction time (P<0.01) and accuracy of performance (P<0.001) of categorical semantic memory. Both the treatments improved libido significantly (P<0.05), while the mood did not change with either. CONCLUSION: The results suggest that both these forms of hormonal replacement therapy improve the efficiency of memory performance and libido. However, a combination of oestradiol and norethisterone acetate seems to be marginally more effective on improving cognitive processes.

Efeitos da administraçäo de dois preparados de ferro sobre alguns parâmetros hematológicos na gravidez / Effect of administration of two preparations ofiron on some hematological parameters in pregnancy

A administraçäo a dois grupos de pacientes grávidas de dois preparados de ferro (ferritina e ferro proteinsuccinilato), capaz de fornecer ferro trivaloente após administraçäo por via oral, demonstrou a capacidade de se opor eficazmente às variaçÆes negativas, induzidas pela gravidez, dos parâmetros hematológicos mais comuns indicativos da sideremia. Foi demonstrado que a porcentagem de absorçäo do ferro é melhor no grupo tratado com oferro proteinsuccinilato, em comparaçäo com o verificado no grupo tratado com ferritina
