Avaliação tardia do eixo hipofisário-gonadal em pacientes adultos que sofreram traumatismo cranioencefálico grave

OBJETIVO: Avaliar a função hipofisária-gonadal nos pacientes vítimas de TCE graves ocorridos na Grande Florianópolis, entre 2000 e 2004. MÉTODOS: Foram estudados 30 pacientes, sendo 22 homens e 8 mulheres, submetidos à avaliação clínica e laboratorial em seguimento médio de 4 anos após a data do traumatismo. RESULTADOS: Os homens possuíam em média 38 anos no ano da avaliação, enquanto as mulheres, 42 anos. A maioria dos traumatismos está relacionada aos acidentes de trânsito (63,3%). Três pacientes (10%) estavam com valores de FSH abaixo do normal e apenas 1 paciente (3,3%) apresentou LH alterado. Nas mulheres avaliadas, os níveis de estradiol foram normais. Na população masculina, foi evidenciado nível de testosterona baixo em 2 pacientes (9,1%). Todos os pacientes apresentavam normoprolactinemia. CONCLUSÃO: Dois casos de hipogonadismo masculino (9,1%) foram diagnosticados neste estudo. Isso indica a necessidade de atenção aos pacientes sobreviventes de TCE grave para realizar diagnóstico precoce de hipogonadismo. OBJECTIVE: The purpose of this study is to evaluate pituitary function impairment in order to verify the prevalence of sex hormone deficiency and to analyze the profile of TBI population. METHODS: Thirty patients were studied, 22 were male and 8 were female. All patients had their gonadal function assessed and they were evaluated at a median of 4 years post-trauma. RESULTS: The average age of the men was 38 years at the time of the evaluation, while the mean age of women was 42 years. The majority of TBI was related to traffic accidents (63.3%). Three patients (10%) had low FSH and only 1 patient (3.3%) had low LH. There was no biochemical evidence of hypogonadism in women. Two male patients presented low testosterone (9.1%) and were diagnosed with hypogonadism. Prolactin levels were normal in all patients. CONCLUSION: Two cases of hypogonadism (9.1%) were diagnosed among men in this study. It is therefore necessary that medical professionals involved in the management of TBI patients are aware of hypogonadism as a complication of TBI, in order to diagnose it early.
