Clomiphene citrate treatment for late onset hypogonadism: rise and fall

ABSTRACT Objective: Previous series have demonstrated that Clomiphene Citrate (CC) is an effective treatment to increase Total Testosterone (TT) in Late Onset Hypogonadism (LOH) patients. However, what happens to TT levels after ending CC treatment is still debatable. The objective of this study is to evaluate TT levels 3 months after the discontinuation of CC in patients with LOH who were previously successfully treated with the same drug. Materials and Methods: Twenty-seven patients with LOH that were successfully treated (achieved TT levels >11nmol/l) with CC 50mgs daily for 50 days were prospectively recruited in our Andrological outpatient clinic. CC was then stopped for 3 months and TT levels were measured at the end of this period. Results: Mean TT level before discontinuation of CC was 22.7±8.1nmol/L (mean±SD). Three months after discontinuation, mean TT level significantly decreased in all patients, 10.2±3.9nmol/l (p<0.01). Twenty-one patients (78%) decreased TT levels under 11nmol/L. Six patients (22%) had TT levels that remained within the normal recommended range (≥11nmol/l). No statistical significant differences were observed between both groups. Conclusion: In the short term LOH does not seem to be a reversible condition in most patients after CC treatment. More studies with longer follow-up are needed to evaluate the kinetics of TT in LOH.

Tear osmolarity and tear function assessment in patients with polycystic ovary syndrome / Avaliação da osmolaridade lacrimal e da função lacrimal em pacientes com síndrome dos ovários policísticos

ABSTRACT Purpose: Polycystic ovary syndrome (PCOS) is an endocrine disease characterized by chronic anovulation and hyperandrogenism. Hormonal changes can affect tear function. This study evaluates tear function and impact of hyperandrogenism on it in PCOS patients. Methods: Fifty patients with PCOS and thirty control volunteers were examined for tear break-up time, Schirmer-I and tear osmolarity. Also, serum levels of total testosterone, FSH, LH and AMH were determined in venous blood samples in the early follicular phase. PCOS patients were divided into two groups by plasma total testosterone level: Group A with normal (≤0.513 ng/ml;n=27), Group B with higher hormone level (>0.513 ng/ml;n=23). Healthy control group indicated as Group C (n=30). Results: LH, total testosterone levels were higher in the PCOS group than in the control group (p=0.012; p=0.025). Mean values of tear break-up time and Schirmer-I were different between groups and especially Group A and C were near to each other differing from B (p>0.05). Tear osmolarity results were higher in Group B, compared to A and C (p=0.049; p=0.033). No significant difference detected in tear osmolarity value means of Group A and C (p=0.107). AMH levels were higher in Group B, compared to A and C (p=0.002; p=0.001). AMH levels in Group A were higher than that of C (p=0.002). Positive correlation between levels of total testosterone and AMH was detected in all PCOS patients (n=50;Pearson's r=0.579; p<0.001). Conclusion: Tear function can be affected in PCOS patients with hyperandrogenism. Tear osmolarity is the most sensitive and objective assessment method for ocular surface changes in PCOS.

RESUMO Objetivo: A síndrome do ovário policístico (SOP) é uma doença endócrina caracterizada por anovulação crônica e hiperandrogenismo. As alterações hormonais podem afetar a função cardíaca. Este estudo avalia a função lacrimal e o impacto do hiperandrogenismo sobre ela em pacientes com SOP. Métodos: Cinquenta pacientes com SOP e trinta voluntárias de controle foram examinadas para tempo de ruptura lacrimal, Schirmer-I e osmolaridade lacrimal. Além disso, os níveis séricos de testosterona total, FSH, LH e HAM foram determinados em amostras de sangue venoso na fase folicular precoce.As pacientes com SOP foram divididas em dois grupos por nível de testosterona plasmática total: Grupo A com nível normal (≤0.513 ng/ml; n = 27), Grupo B com nível superior de hormônio (> 0,513 ng/ml; n = 23). Grupo de controle saudável indicado como Grupo C (n = 30). Resultados: Os níveis de LH e testosterona total foram maiores no grupo com SOP do que no grupo controle (p = 0,012; p = 0,025). Os valores médios de tempo de ruptura lacrimal e Schirmer-I foram diferentes entre os grupos, e especialmente os Grupos A e C estavam próximos um do outro, diferente do B (p > 0,05). Os resultados de osmolaridade lacrimal foram maiores no Grupo B, em comparação com A e C (p = 0,049; p = 0,033). Não houve diferença significativa detectada em valor médio de osmolaridade lacrimal nos Grupos A e C (p = 0,107). Os níveis de HAM foram maiores no Grupo B, em comparação com A e C (p = 0,002; p = 0,001). Os níveis de AMH no Grupo A foram superiores aos de C (p = 0,002). Uma correlação positiva entre os níveis de testosterona total e AMH foi detectada em todas as pacientes com SOP (n = 50; Pearson's r = 0,579; p < 0,001). Conclusão: a função lacrimal pode ser afetada em pacientes com SOP com hiperandrogenismo. A osmolaridade lacrimal é o método de avaliação mais sensível e objetivo para alterações da superfície ocular em SOP.

Poor sleep in middle-aged women is not associated with menopause per se

Whether sleep problems of menopausal women are associated with vasomotor symptoms and/or changes in estrogen levels associated with menopause or age-related changes in sleep architecture is unclear. This study aimed to determine if poor sleep in middle-aged women is correlated with menopause. This study recruited women seeking care for the first time at the menopause outpatient department of our hospital. Inclusion criteria were an age ≥40 years, not taking any medications for menopausal symptoms, and no sleeping problems or depression. Patients were assessed with the Pittsburgh Sleep Quality Index (PSQI), modified Kupperman Index (KI), and Menopause Rating Scale (MRS). A PSQI score of <7 indicated no sleep disorder and ≥7 indicated a sleep disorder. Blood specimens were analyzed for follicle-stimulating hormone and estradiol levels. A total of 244 women were included in the study; 103 (42.2%) were identified as having a sleep disorder and 141 as not having one. In addition, 156 (64%) women were postmenopausal and 88 (36%) were not menopausal. Follicle-stimulating hormone and estradiol levels were similar between the groups. Patients with a sleep disorder had a significantly higher total modified KI score and total MRS score (both, P<0.001) compared with those without a sleep disorder. Correlations of the PSQI total score with the KI and MRS were similar in menopausal and non-menopausal women. These results do not support that menopause per se specifically contributes to sleep problems.

Nanostructured transdermal hormone replacement therapy for relieving menopausal symptoms: a confocal Raman spectroscopy study

OBJECTIVE: To determine the safety and efficacy of a transdermal nanostructured formulation of progesterone (10%) combined with estriol (0.1%) + estradiol (0.25%) for relieving postmenopausal symptoms. METHODS: A total of 66 postmenopausal Brazilian women with climacteric symptoms of natural menopause received transdermal nanostructured formulations of progesterone and estrogens in the forearm daily for 60 months to mimic the normal ovarian secretory pattern. Confocal Raman spectroscopy of hormones in skin layers was performed. Clinical parameters, serum concentrations of estradiol and follicle-stimulating hormone, blood pressure, BI-RADS classification from bilateral mammography, and symptomatic relief were compared between baseline and 60 months post-treatment. Clinicaltrials.gov: NCT02033512. RESULTS: An improvement in climacteric symptoms was reported in 92.5% of women evaluated before and after 60 months of treatment. The serum concentrations of estradiol and follicle-stimulating hormone changed significantly (p<0.05) after treatment; the values of serum follicle-stimulating hormone decreased after 60 months from 82.04±4.9 to 57.12±4.1 IU/mL. A bilateral mammography assessment of the breasts revealed normal results in all women. No adverse health-related events were attributed to this hormone replacement therapy protocol. CONCLUSION: The nanostructured formulation is safe and effective in re-establishing optimal serum levels of estradiol and follicle-stimulating hormone and relieving the symptoms of menopause. This transdermal hormone replacement therapy may alleviate climacteric symptoms in postmenopausal women. .

Perfil hormonal sexual de mulheres em programa crônico de diálise em tratamento com eritropoetina humana recombinante / Sex hormones profile in women on dialysis program in treatment with erythropoietin

A IRC (insuficiência renal crônica) terminal é acompanhada por alterações sistêmicas, inclusive do eixo hipotálamo-hipofisário-gonadal. Após o aparecimento da EPO (eritropoetina humana recombinante), surgiram relatos de melhora da disfunção sexual em homens, havendo relativa escassez de dados sobre dosagens hormonais e função sexual das mulheres. No Brasil, há poucos dados sobre o perfil hormonal de mulheres em programa crônico de diálise. OBJETIVOS: Avaliação e comparação do perfil hormonal sexual, através das dosagens de FSH (hormônio folículo estimulante), LH (hormônio luteinizante), PRL (prolactina) e E2 (estradiol) de mulheres em programa crônico de diálise, sob terapêutica com EPO. MÉTODOS: Foram avaliadas 47 mulheres (uma em diálise peritoneal intermitente, quatro em diálise peritoneal ambulatorial contínua e 42 em hemodiálise), subdivididas em três grupos: (1) Grupo I, de mulheres com menos de 48 anos de idade e menstruando regularmente; (2) Grupo II, de mulheres com menos de 48 anos de idade e amenorreicas; (3) Grupo III, de mulheres com mais de 48 anos de idade e amenorreicas. Os grupos foram comparados entre si através do teste de Mann-Whitney para duas amostras independentes. RESULTADOS: Todos os grupos mostraram valores normais das dosagens séricas de FSH, LH e E2, e não houve diferença estatisticamente significante nos níveis desses hormônios entre as mulheres que menstruam e as amenorreicas com idade inferior a 48 anos. Os níveis de PRL encontravam-se acima da normalidade em todos os grupos, independentemente da idade e do padrão menstrual, não havendo diferenças estatísticas significantes entre os grupos. As pacientes do grupo III apresentaram perfis hormonais compatíveis com a menopausa, ou seja, níveis séricos de FSH e LH elevados e de E2 diminuídos

Gonadotropinas y sexoesteroides en mujeres posmenopáusicas del círculo de abuelos

En publicaciones recientes se han evaluado varios factores que pueden influir en las hormonas de la reproducción durante el climaterio. En nuestro medio no existen investigaciones sobre esta problemática, razón por la cual se diseñó este estudio con el objetivo de conocer la relación entre los niveles hormonales posmenopáusicos y la actividad en los círculos de abuelos. Se seleccionó una muestra simple aleatoria de 134 mujeres posmenopáusicas, estratificada según participaran o no en el círculo de abuelos (67 en cada estrato), de un área de salud urbana. Se determinaron por radioinmunoanálisis las siguientes hormonas: FSH, LH, prolactina, testosterona, estradiol 17 beta, androstenediona y 17 hidroxiprogesterona (17 OH-P). La prolactina fue mayor en las mujeres que no participan en las actividades del círculo de abuelos, mientras que la testosterona y la 17 OH-P fueron menores con respecto al grupo que participa en el círculo de abuelos. El resto de las hormonas no mostró diferencias entre los 2 grupos. Según estos resultados, las actividades realizadas por estas mujeres en el círculo de abuelos influyen en los niveles de algunas de las hormonas de la reproducción, lo que pudiera tener efectos favorables para la salud, al disminuir el estrés y en particular sobre la osteoporosis que se desarrolla en esta época de la vida
