ABSTRACT

OBJECTIVE: To assess the efficacy and safety of testosterone replacement in males with late-onset hypogonadism compared to hypogonadal men without replacement, and controls, during six months. METHODS: We assessed, through ADAM, AMS, IIEF-5 and SF-36 questionnaires, and through clinical and laboratorial examinations, 62 patients divided into three groups: 17 hypogonadal males (HR) used intramuscular testosterone every three weeks; 14 hypogonadal males (HV) and 31 non-hypogonadal males (CV) used oral vitamins daily. RESULTS: When compared to others, HR group obtained libido improvement assessed by ADAM 1 (p = 0.004), and borderline sexual potency improvement assessed by IIEF-5 (p = 0.053), besides a decrease in waist circumference after eight weeks (p = 0.018). The remaining parameters did not differ between the groups. PSA and hematocrit remained stable in those using testosterone. CONCLUSION: Six months of testosterone replacement improved sexuality and body composition, with prostatic and hematological safety.


OBJETIVO: Avaliar a eficácia e a segurança da reposição de testosterona em homens com hipogonadismo tardio comparados a hipogonádicos sem reposição e controles, durante seis meses. MÉTODOS: Mediante os questionários ADAM, AMS, IIEF-5 e SF-36, foram feitos exame clínico e laboratorial em 62 pacientes divididos em três grupos: 17 hipogonádicos (HR) usaram testosterona intramuscular a cada três semanas; 14 hipogonádicos (HV) e 31 não hipogonádicos (CV) usaram vitaminas via oral diariamente. RESULTADOS: Comparado aos demais, o grupo HR obteve melhora da libido avaliada pelo ADAM 1 (p = 0,004) e melhora limítrofe da potência sexual avaliada pelo IIEF-5 (p = 0.053), além de diminuição da cintura a partir da oitava semana (p = 0,018). Os demais parâmetros não foram diferentes entre os grupos. PSA e hematócrito se mantiveram estáveis nos que usaram testosterona. CONCLUSÃO: A reposição de testosterona durante seis meses melhorou a sexualidade e a composição corporal, com segurança prostática e hematológica.

ABSTRACT

OBJECTIVES: To evaluate which factors influence the laboratorial diagnosis of late-onset male hypogonadism (LOH). METHODS: Total testosterone (TT), SHBG and albumin were measured in 216 men aged 52-84 years. The laboratorial definition of LOH was two values of calculated free testosterone (cFT) <6.5 ng/dl, according to Vermeulen's formula. RESULTS: At the first blood test, cFT was <6.5 ng/dl in 27 percent of the men. Laboratorial LOH (confirmed by two tests) was present in 19 percent, but TT levels were low in only 4.1 percent. Age influenced TT (p=0.0051) as well as BMI; 23.5 percent of patients > 70 years and 38.9 percent of the obese men who had TT within the reference range were, in fact, hypogonadal. CONCLUSION: Especially in obese men and in those > 70 years old, SHBG dosage is important to calculate FT levels and diagnose hypogonadism.


OBJETIVOS: Avaliar os fatores que influenciam o diagnóstico laboratorial do hipogonadismo masculino tardio. MÉTODOS: Avaliamos 216 homens entre 52 e 84 anos. O diagnóstico laboratorial foi definido como dois valores de testosterona livre calculada (TLC) <6,5 ng/dl, segundo a fórmula de Vermeulen, a partir das dosagens de testosterona total (TT), SHBG e albumina. RESULTADOS: Na primeira dosagem, a TLC foi <6.5 ng/dl em 27 por cento da amostra. Hipogonadismo laboratorial (confirmado por duas dosagens) esteve presente em 19 por cento, no entanto a TT foi baixa em apenas 4.1 por cento dos homens. A idade influenciou a TT (p=0.0051) bem como o IMC; 23,5 por cento dos homens > 70 anos e 38,9 por cento dos obesos com TT dentro dos níveis de referência eram, na verdade, hipogonádicos. CONCLUSÃO: Especialmente em homens obesos e nos > 70 anos a dosagem de SHBG é importante para calcular TL e diagnosticar o hipogonadismo.

ABSTRACT

OBJECTIVE: To analyze the relative risk of late-onset hypogonadism in men with osteoporosis and the usefulness of screening questionnaires. METHODS: We correlated the Aging Male's Symptoms (AMS), Androgen Deficiency in Aging Male (ADAM) and International Index of Erectile Function (IIEF-5) questionnaires and the laboratory diagnosis of hypogonadism in 216 men aged 50-84 years (110 with osteoporosis and 106 with normal bone density, paired by age and ethnicity). RESULTS: Hypogonadism presented in 25 percent of the osteoporotic and in 12.2 percent of normal bone density men (OR 2.08; IC95 percent: 1.14-3.79) and was associated with ADAM first question (low libido, p=0.013). Levels of TT below 400 ng/dl correlated with an AMS score above 26 (p=0.0278). IIEF-5 showed no correlation with testosterone levels. CONCLUSION: Hypogonadism was 2.08 times more prevalent in osteoporotic men. The symptom that best correlated with late-onset hypogonadism was low libido (ADAM 1 positive).


OBJETIVOS: Avaliar o risco relativo de hipogonadismo tardio em homens com osteoporose e a utilidade de questionários de triagem. MÉTODOS: Correlacionamos a pontuação dos questionários Aging Male's Symptoms (AMS), Androgen Deficiency of the Aging Male (ADAM) e International Index of Erectile Function (IIEF-5) com dosagens de testosteronas em 216 homens entre 50 e 84 anos (110 com osteoporose e 106 com densidade óssea normal, pareados por idade e etnia). RESULTADOS: Hipogonadismo ocorreu em 25 por cento dos osteoporóticos e em 12,2 por cento dos com densidade óssea normal (RR 2,08; IC95 por cento: 1,143,79) e esteve associado à pergunta 1 do ADAM (diminuição de libido, p = 0,013). Testosterona total < 400 ng/dL associou-se a AMS > 26 (p = 0,0278). Disfunção erétil, avaliada pelo IIEF-5, não se correlacionou com dosagens de testosteronas. CONCLUSÃO: Hipogonadismo foi 2,08 vezes mais prevalente em homens com osteoporose e esteve associado à diminuição da libido (ADAM 1 positivo).
