ABSTRACT

OBJECTIVE: To investigate the efficacy of a transdermal nanoemulsion testosterone associated with transdermal estrogen therapy as a novel protocol treatment for emergent loss of libido. METHODS: Twenty-four women, aged 31-75 years (mean age, 51.7), with emergent loss of libido were allocated to treatment with a novel transdermal formulation of 500 µg/day of testosterone (Biolipid/B2®-testosterone) for 12 weeks, as part of an open label prospective study on peri- and post-menopausal women. Subjects applied the formulation on the right forearm. Clinical and laboratorial parameters including the sexual complaints; serum concentrations of testosterone, insulin, C-reactive protein, weight, blood pressure; body mass index and waist circumference were compared between baseline and 12 weeks after treatment. RESULTS: The mean total serum testosterone increased significantly (p = 0.009) after 12 weeks of treatment. No adverse or androgenic events were observed. There were positive and significant differences (p < 0.05) on sexual complaints, blood pressure, body mass index and waist circumference after transdermal nanoemulsion testosterone treatment. CONCLUSION: This protocol is effective in increasing testosterone levels in peri- and postmenopausal women with low libido.


OBJETIVO: Investigar a eficácia de uma nanoemulsão transdérmica de testosterona associada à terapia com estrogênio transdérmico como tratamento para a perda emergente da libido. MÉTODOS: Vinte e quatro mulheres, com idade entre 31-75 anos (idade média de 51,7), com perda emergente de libido foram incluídas num protocolo para tratamento de libido reduzida com uma formulação transdérmica de 500 µg/dia de testosterona (biolípido/B2®-testosterona) com 12 semanas de duração, como parte de um estudo prospectivo aberto em mulheres peri- e pós-menopausa. As participantes aplicaram a formulação no antebraço direito. Os parâmetros clínicos e laboratoriais, incluindo as queixas sexuais foram comparados entre os valores iniciais e 12 semanas após o tratamento. Mediram-se as concentrações séricas de testosterona, insulina, proteína C-reactiva, o peso, a pressão arterial; o índice de massa corporal e a circunferência da cintura. RESULTADOS: A média de testosterona total no soro aumentou significativamente (p = 0,009) após 12 semanas de tratamento. Não foram observados efeitos adversos ou androgênicos. Registraram-se reduções significativas (p < 0,05) sobre as queixas sexuais, da pressão arterial, do índice de massa corporal e da circunferência da cintura após o tratamento transdérmico com nanoemulsão de testosterona. CONCLUSÃO: O protocolo mostrou eficacia em aumentar os níveis de testosterona em e melhorar a libido em mulheres peri e pós-menopausa com baixa libido.

ABSTRACT

Hipogonadismo de comienzo tardío, es una condición que afecta 6% al 12% de hombres entre 40 y 70 años y aun así, está subdiagnosticada, por lo que se propone un cuestionario de validación diagnóstica, con el objetivo de lograr mayor sensibilidad, especifidad y predictividad que los cuestionarios ya existentes. Se analizaron 107 hombres entre 45 y 70 años, con disminución del entusiasmo en actividad diaria, cansancio fácil, menor productividad en su trabajo, cambios del humor con propensión a la irritabilidad, disminución de su masa magra muscular, con tendencia al sobrepeso y afectación en actividades recreativas y deportivas. Se hizo interrogatorio exhaustivo, examen físico y pruebas de laboratorio (perfil 20, perfil hormonal urológico masculino, antígeno prostático específico total, libre y relación libre/total, examen de orina y urocultivo). Se solicitó contestar al paciente tres cuestionarios de validación diagnóstica del hipogonadismo de comienzo tardío: Heinemann AMS (Ageing Males Survey-1999, St. Louis University, Androgen Deficiency in Aging Male), Morley ADAM-2000 y el cuestionario de validadción diagnóstica del hipogonadismo de comienzo tardío-Potenziani-2007, para ser comparados y demostrar su validez con pruebas de especificidad y sensibilidad, índice de Youden, pruebas de concordancia con intervalos de confianza del 95%, en relación al diagnóstico bioquímico del hipogonadismo de comienzo tardío. Los resultados arrojaron que el cuestionario "Potenziani" fue más sensible (88,57%), fue más específico (41,67%), tuvo el índice de validez más alto (57,01%) y el valor predictivo positivo más alto de los tres cuestionarios con el 42,5%. Por tal motivo se ha demostrado que el cuestionario propuesto es más adecuado que Heineman-AMS y el Morley-ADAM en la aproximación diagnóstica del síndrome de hipogonadismo de comienzo tardio


Late onset hypogonadism a condition which affect 6%-12% of men between 40-70 years old, and still it is subdiagnosed for which we did a validation questionnaire with the objetive to be more sensitive, especific and predictive that old questionnaires. We analized 107 men with ages between 45-70 years old whom consulted for libido deterioration, erectile dysfunction, less enthusiasm of daily life, less work-productivity, easy tiredness, humor changes with irritability, less muscle mass, overweight, and deterioration of sexual life in general. We performed exhaustive interrogatory, physical examination, and laboratoty test (20 profile, hormonal-urologic profile, prostatic specific antigen, urine and urocultive). We ask them to complete three questionnaires of late onset hypogonadism diagnostic validation: Heinemann AMS, Morley ADAM, Potenziani 2007, to be compared and show its validity with specificity and sensibility tests, Youden Index, test of concordance with confidence interval of 95%, in relation to biochemical diagnosis of deficiency testosterone syndrome. The results were that the Potenziani`s cuestionary was more sensible (88.57%), more specific (41.67%), with the validation index more high (57.01%) and with the positive predictive value more high too (42.5%). For that reason we show that Potenziani`s validation questionnaire of late onset hypogonadism, is more adecuate in the diagnostic aproximation of this condition

ABSTRACT

El Síndrome de Deficiencia de Testosterona constituye hoy en día una entidad relevante dentro de las patologías del hombre adulto. Contrariamente a los mitos existentes, la evidencia científica actual demuestra que la Testosterona no sólo está involucrada en el área sexual y reproductiva, sino también en muchos otros sistemas como el cardiovascular, el metabolismo lipídico, la composición corporal, el metabolismo óseo, la función cerebral y el sistema hematopoyético. En todos ellos, su deficiencia puede generar serios efectos que implican un severo impacto en la calidad de vida del hombre mayor. Por otra parte, el conocimiento médico actual permite hoy en día reemplazar esta hormona sin temores. Sabemos que la testosterona no induce la aparición de cáncer de próstata así como también aquellos hombres con testosterona plasmática baja tienen más riesgo de hacer este cáncer así como también más agresivos. El reemplazo hormonal, con la consecuente restauración de los niveles plasmáticos de testosterona genera una mejoría en cada uno de los sistemas afectados lo que finalmente se traduce en una mejoría en la calidad de vida.


The testosterone deficiency syndrome is currently a well established entity amongst adult male pathology. Current evidence demonstrates testosterone involvement not only in sexual and reproductive physiology but also as an active participant in other systems. Cardiovascular system, lipid metabolism, body composition, bone metabolism, brain function and hemathopoyetic system are all severely affected by androgen deficiency. It is well known that testosterone administration does not induce prostate cancer nor it is associated with a higher risk of high grade cancer in the hypogonadic male. Now a days testosterone can be administered without fear. Hormone replacement therapy with normalization of plasmatic testosterone levels is associated with a recovery of all systems affected and consequently an improvement in quality of life.
