Abstract in Portuguese
Objetivo: Avaliar marcadores de reserva ovariana e a presença de anticorpo anti-corpo lúteo (anti-CoL) em pacientes com arterite de Takayasu (AT) e possível associação com parâmetros clínicos, laboratoriais e uso de imunossupressores. Métodos: 20 pacientes com AT e 24 controles saudáveis foram avaliados para anti-CoL (immunoblot). A reserva ovariana foi avaliada por: hormônio folículo estimulante (FSH), hormônio luteinizante (LH), estradiol, hormônio anti-Mülleriano (HAM) e contagem de folículos antrais (CFA). HAM foi dosado por ELISA utilizando dois diferentes testes. Dados demográficos, obstétricos, alterações menstruais, aspectos clínicos, imagens vasculares e tratamento foram também analisados. Resultados: A média da idade atual foi similar em pacientes e controles (31,2 ± 6,1 vs. 30,4 ± 6,9 anos, p = 0,69). As frequências de HAM baixo foram idênticas em pacientes com AT com ambos os testes de ELISA e maiores quando comparadas ao grupo controle (50% vs.17%, p=0,02, 50% vs. 19%, p=0,048). Observou-se uma correlação positiva entre os dois testes de ELISA em pacientes (r=0,93, p < 0,0001) e em controles saudáveis (r=0,93, p < 0,0001). Pacientes com AT apresentaram menor CFA (11 vs. 16, p=0,13) e maior frequência de CFA reduzida (41% vs. 22%, p=0,29), contudo sem significância estatística. Não foram encontradas diferenças entre os dois grupos em relação às outras características demográficas e clínicas, dados obstétricos e demais parâmetros da reserva ovariana (p > 0,05). Anti-CoL foi observado apenas em uma paciente com AT (5% vs. 0%, p = 0,45). Avaliação adicional das mulheres com AT comparando as com baixos níveis de HAM ( < 1,0 ng/mL) versus aquelas com níveis de HAM QRUPD ng/mL) não mostrou diferença entre os dois grupos em relação a duração da doença, atividade de doença, provas de fase aguda, exames de imagem vascular e tratamento (p > 0,05). Conclusão: O presente estudo foi o primeiro a sugerir que as pacientes com AT podem apresentar reserva ovariana diminuída

Abstract in English
Objective: To assess ovarian reserve markers and anti-corpus luteum antibodies (anti-CoL) in Takayasu arteritis (TA) patients and a possible association with clinical and laboratory parameters and the use of immunosuppressive drugs. Methods: 20 TA and 24 healthy controls were evaluated for anti-CoL (immunoblot). Ovarian reserve was assessed by: follicle stimulating hormone (FSH), luteinizing hormone (LH), estradiol, antiMüllerian hormone (AMH) and antral follicle count (AFC). AMH was measured by ELISA using two different kits. Demographical data, menstrual abnormalities, obstetric data, clinical features, vascular imaging and treatment were also analyzed. Results: The mean current age was similar in TA patients and controls (31.2 6.1 vs. 30.4 6.9 years, p=0.69). The frequencies of decreased levels of AMH in TA patients were identical using both kits and higher when compared to controls (50% vs. 17%, p=0.02; 50% vs. 19%, p=0.048). A positive correlation was observed between the two kits in TA patients (r=+0.93; p < 0.0001) and in healthy controls (r=+0.93; p < 0.0001). The apparent lower AFC (11 vs. 16, p=0.13) and the higher frequency of low AFC (41% vs. 22%, p=0.29) in TA compared to controls did not reach statistical significance. No differences between the two groups were found concerning other demographic and clinical characteristics, obstetric data and other parameters of ovarian reserve (p > 0.05). Anti-CoL was solely observed in TA patients (5% vs. 0%, p=0.45). Further evaluation of TA patients comparing patients with low AMH levels ( < 1.0ng/mL) versus normal AMH levels (.- 1.0ng/mL) revelead no differences regarding disease duration, disease activity, acute phase reactants, vascular imaging and treatment between these two groups (p > 0.05). Conclusions: The present study was the first to suggest that TA patients may have diminished ovarian reserve
