Paullinia cupana para o controle de fogachos em pacientes com câncer de mama: um estudo piloto / Paullinia cupana for control of hot flashes in breast cancer patients: a pilot study

OBJETIVO: Avaliar se a Paullinia cupana diminui o número e a gravidade dos fogachos em mulheres após diagnóstico de câncer de mama. MÉTODOS: Estudo piloto prospectivo fase II realizado com mulheres que sobreviveram ao câncer de mama, que completaram o tratamento pelo menos 3 meses antes e que apresentavam ao menos 14 episódios de fogachos por semana. Utilizando o desenho de Simon para que a primeira etapa fosse considerada positiva, ao menos 9 de 15 mulheres deveriam ter a gravidade dos fogachos diminuída em pelo menos 50%. As pacientes receberam 50mg do extrato seco de Guaraná oralmente 2 vezes por dia por 6 semanas. Foram avaliadas, a gravidade e a frequência dos fogachos. RESULTADOS: Dezoito pacientes iniciaram o tratamento com Paullinia cupana e 15 completaram o estudo. Três pacientes deixaram o estudo imediatamente após iniciarem o tratamento em razão de dificuldade na participação e não adesão. Das 15 pacientes que completaram o estudo, 10 obtiveram diminuição de mais de 50% dos índices de gravidade de fogachos. Durante as 6 semanas de tratamento, diminuições estatisticamente significativas foram observadas tanto no número de fogachos (p=0,0009), quanto nos índices de gravidade (p<0,0001). Paullinia cupana foi bem tolerada, e não houve relato de toxicidade como causa de saída do estudo. CONCLUSÕES: Paullinia cupana pareceu promissora para o controle de fogachos. Estudos mais extensivos são necessários.

OBJECTIVE: To evaluated whether Paullinia cupana decrease number and severity of hot flashes in breast cancer survivors. METHODS: This was a prospective phase II pilot study. We studied female breast cancer survivors who had completed the cancer treatment 3 months previously and who were experiencing at least 14 hot flashes per week. At least 9 of the 15 patients were required to have a decrease of at least 50% in hot flash severity score in keeping with the Simon Design. Patients received 50mg of dry extract of Paullinia cupana orally twice a day for 6 weeks. We assessed both frequency and severity of hot flashes. RESULTS: A total of 18 patients started the Paullinia cupana treatment, and 15 completed the study. Three patients left the study immediately after starting the treatment because of personal difficulties in participation or noncompliance. Of the 15 patients who completed the study 10 had a decrease of more than 50% in hot flash severity scores. During the 6 weeks of treatment, statistically significant decreases were seen in both numbers of hot flashes (p=0.0009) and severity scores (p<0.0001). Paullinia cupana was well tolerated, and there were no instances of discontinuation because of toxicity. CONCLUSIONS: Paullinia cupana appears promising for controlling hot flashes. More extensive studies seem warranted.

Síntomas climatéricos y calidad de vida de usuarias de consultorios de atención primaria de salud, Santiago / Lifestyles and quality of life of post menopausal women

Background: During menopause the quality of life of women can be seriously deteriorated and influenced by lifestyles. Aim: To assess the prevalence of menopausal symptoms and their relationship with lifestyles and quality of life. Material and Methods: The Menopause Rating Scale (MRS), a survey that measures menopausal symptoms and has questions related to lifestyles, was applied to 1023 women aged 54 ± 6years (range 45 to 64years), consulting in primary health care clinics. A multiple linear regression analysis was used to evaluate the association between menopausal symptoms and lifestyle. Results: Fifty six percent of women did not have a paid work, 64 percent were nonsmokers and 90 percent did not perform any physical exercise. The most frequent menopausal symptoms referred were muscle and joint ailments (85 percent) followed by mental and physical exhaustion (80 percent). Sedentary women, smokers or those who did not to have time for leisure activities showed worst quality of life scores. Conclusions: Postmenopausal women with unhealthy lifestyles had the lower quality of life scores and more menopausal symptoms.

Terapia não-hormonal no manejo das ondas de calor no climatério / Non-hormonal therapy in the management of hot flushes in climateric

A menopausa, ponto máximo do climatério, é um evento acompanhado frequentemente por sintomas vasomotores, podendo ter um impacto significativo na qualidade de vida da mulher. A maioria das mulheres experimentará fogachos em algum momento de suas vidas com frequência e intensidade variáveis. Apesar das inúmeras teorias, a fisiopatologia exata dos fogachos ainda não é conhecida. Existem muitas opções de terapias farmacológicas hormonais e não-hormonais, até intervenções não-farmacológicas, e escolher a melhor opção de tratamento para cada mulher envolve o conhecimento dos possíveis riscos e benefícios de cada tratamento, necessitando de individualização na conduta. O tratamento hormonal (estrogênio e/ou progesterona) ainda é a opção mais utilizada, o qual se tem mais estudos realizados com esta modalidade de tratamento, resultando em uma redução de 80 a 90% dos fogachos, entretanto, cada vez mais são procuradas terapias alternativas. O manejo não-hormonal com melhores resultados tem sido conseguido com a classe dos antidepressivos mais recentes, a qual compreende vários inibidores seletivos da recaptação da serotonina, alguns fornecendo redução de cerca de 60% dos fogachos. Este artigo procurou avaliar as opções de terapias não-hormonais disponíveis para o controle dos sintomas climatéricos, seus efeitos colaterais e mecanismos de ação.

Menopause, the highest point of climateric, is frequently followed by vasomotor symptoms and may case a large impact in women's quality of life. The majority of women will experience episodes of hot flushes at various frequencies and intensities during their lives. Despite many theories about the physiopathology of hot flushes, the exact cause is still unknown. Different treatments for climacteric symptoms are available, such as hormonal and non-hormonal therapies, and non-pharmacological intervention also becomes an option. Choosing the best treatment requires ample knowledge of each therapy risks and benefits, and it is necessary to individualize the treatment for each woman. The hormonal therapy (estrogens and/or progestins) is still the most applied option. Accomplished studies about this kind of treatment demonstrated that it can reduce the intensity of hot flushes from 80 up to 90%; however, more and more women are searching for alternative therapies. The non-hormonal therapy with the best result involves the most recent class of antidepressant drugs, which includes many selective serotonin reuptake inhibitors, some of them reducing hot flushes up to 60%. This article aimed at evaluating non-hormonal therapy options available to control climacteric symptoms, their side effects and mechanism of action.

Evaluation of core and surface body temperatures, prevalence, onset, duration and severity of hot flashes in men after bilateral orchidectomy for prostate cancer

OBJECTIVE: To assess the prevalence, onset, duration and severity of hot flashes in men after bilateral orchidectomies (BO) for prostate cancer, to evaluate body temperature changes during hot flashes and to determine whether an elevated temperature within a few days after BO can be caused by deprivation of androgen. MATERIALS AND METHODS: Patients (n = 101) were questioned about the characteristics of their hot flashes after BO for prostate cancer. A subgroup of these men (n = 17) were instructed to record their oral and forehead temperatures during and at fixed intervals between hot flashes daily for 4 weeks. RESULTS: The mean age was 71.6 years, mean follow-up after BO was 33.2 months. Hot flashes were reported by 87 men (86 percent) with previous spontaneous remission in 9 (10 percent). The median time between BO and the onset of hot flashes was 21 days (range 1-730), median number of hot flashes 3 per day (range 1-20), and median duration was 120 seconds (range 5 to 1800). There was no significant difference between median oral (36.4º C) and forehead (36.0º C) temperature in the normal state, but during hot flashes the median forehead temperature (37.0º C) was higher than the oral temperature (36.5º C) (p = 0.0004). Both median oral and forehead temperatures were higher during hot flashes (36.5º C and 37.0º C) than in the normal state (36.4º C and 36.0º C, respectively) (p < 0.0001). During hot flashes, the oral temperature was 38º C to 40º C in only 3.2 percent of 593 readings in 17 patients. CONCLUSIONS: The median oral and forehead temperatures are higher during hot flashes than in normal periods. Oral temperature elevation > 38º C within days after a BO is unlikely to be the result of androgen deprivation alone.

Fatores associados à intensidade das ondas de calor em mulheres em climatério / Factors associated with the intensity of hot flashes in climacteric women

OBJETIVO: Identificar os fatores associados à intensidade das ondas de calor em mulheres climatéricas em Campinas, São Paulo. MÉTODOS: Análise secundária de banco de dados de estudo descritivo de coorte transversal, de base populacional. Foram selecionadas 334 mulheres com ondas de calor, por amostragem, entre 45-60 anos. Os dados foram coletados por meio de entrevistas domiciliares, com questionários estruturados e pré-testados, fornecidos pela Fundação Internacional de Saúde/Sociedade Internacional de Menopausa, Sociedade Norte-Americana de Menopausa, e adaptados pelos autores, e a intensidade das ondas de calor mensurada por meio do índice circulatório. Avaliou-se a idade, uso de métodos anticoncepcionais, terapia hormonal, laqueadura tubária, índice de massa corpórea, estado menopausal, tempo de menopausa, antecedente de histerectomia, ooforectomia bilateral e tabagismo. Calculou-se a mediana e as freqüências absolutas e relativas, de acordo com o tipo de variável. A medida de associação foi a razão de prevalência (RP). Realizou-se análise bivariada e de regressão múltipla para identificação dos fatores associados à intensidade das ondas de calor, com intervalo de confiança de 95 por cento (IC 95 por cento). RESULTADOS: Mulheres com tempo de menopausa superior a 61 meses (RP: 0,59; IC 95 por cento: 0,39-0,88) apresentaram chance significativamente menor de referir ondas de calor intensas enquanto o antecedente de ooforectomia bilateral (RP: 1,95; IC 95 por cento: 1,08-3,50) associou-se significativamente à intensidade das ondas de calor. CONCLUSÃO: Os fatores associados às ondas de calor de maior intensidade, tempo de menopausa e ooforectomia bilateral sugerem o hipoestrogenismo como causa comum para as ondas de calor intensas. Mulheres com esses fatores devem receber atenção especializada, minimizando as repercussões negativas das ondas de calor.

OBJECTIVE: To identify factors associated with the intensity of hot flashes in 334 climacteric women living in Campinas, São Paulo, Brasil. METHODS: Secondary analysis of a data bank of a descriptive cross-sectional population-based study. Selection of 334 women reporting hot flashes aged 45-60 years was carried out through cluster sampling. Data were collected by home interviews using a structured, pre-tested questionnaire provided by the International Health Foundation/International Menopause Society and by the North American Menopause Society and adapted by the authors. Intensity of hot flashes was measured using the circulatory index. The variables analyzed were age, use of contraceptive methods and hormonal therapy, tubal ligation, body mass index, menopausal status, time since menopause, hysterectomy, bilateral oophorectomy and smoking. Statistical analysis was performed by using the median, absolute and relative frequencies according to the type of variable. The prevalence ratio (PR) was used to measure association. Bivariate analysis and multiple logistic regression with a 95 percent confidence interval (95 percent CI) were used to identify the factors associated with the intensity of hot flashes. RESULTS: Women with time since menopause of over 61 months (PR: 0.59; IC 95 percent: 0.39-0.88) had a significantly lower chance of presenting intense hot flashes while the antecedent of bilateral oophorectomy (PR: 1.95; IC 95 percent: 1.08-3.50) was significantly associated with the intensity of hot flashes. CONCLUSION: Both factors, time since menopause and bilateral oophorectomy, suggest hypoestrogenism as a common cause of more intense hot flashes. Women with these factors should receive specialized care to minimize the negative effects of hot flashes.
