ABSTRACT

Prolactin (PRL) is a hormone characterized by its immunomodulatory properties. The aim of this study was to evaluate the prevalence of thyroid autoimmunity in patients with prolactinoma. Seventy-seven patients and 56 healthy individuals in the control group, sex and age matched, had their serum PRL, free tetraiodothyronine, thyroid-stimulating hormone and anti-thyroid peroxidase (anti-TPO) levels measured. The prevalence of anti-TPO for patients was 13% and 8.9% for control group (p = 0.58). The analysis of subgroups of patients, divided in accordance with tumor size at diagnosis, showed no significant difference in the frequency of anti-TPO. However, when they were divided in accordance with the prolactin levels at the moment of the study, 18.8% with valid hyperprolactinemia and 3.4% without hyperprolactinemia had positive autoantibody (p = 0.07). In conclusion, there was no greater prevalence of thyroid autoimmunity in patients with prolactinoma. Nevertheless, those with valid hyperprolactinemia showed a greater tendency for positive autoantibody anti-TPO

ABSTRACT

Os autores analisam os métodos laboratoriais clássicos e os mais modernos empregados no diagnóstico das formas cutânea, cutâneo-mucosa e cutâneo-difusa da leishmaniose. Discutem sua metodologia e indicação no curso evolutivo da doença. O achado da Leishmania no esfregaco, fragmentos de biópsia e/ou na cultura, e o teste de Montenegro permanecem como os melhores parâmetros na decisão terapêutica, em especial em locais de infra-estrutura sanitária e laboratorial precária. Os métodos mais sensíveis e específicos para a detecção de formas amastigotas, entre eles a hibridizacão e a PCR, podem ser aplicados, particularmente, nos casos de dúvida. Os recentes avanços na biologia molecular vêm possibilitando o diagnóstico cada vez mais preciso da espécie da Leishmania, cuja caracterização tem implicações epidemiológicas, prognósticas e terapêuticas. Contudo os critérios clínico-epidemiológicos permanecem fundamentais para o diagnostico dessa dermatozoonose.
