ABSTRACT

OBJETIVO: Avaliar a resposta ovariana após uso de ciclofosfamida (CFM) em pacientes com lúpus eritematoso sistêmico (LES) e correlacionar os achados de tempo de doença e idade no período de utilização de CFM e dose cumulativa com alterações no ciclo menstrual e/ou evolução para insuficiência ovariana (IO). MÉTODOS: Foi um estudo transversal, retrospectivo, com 50 pacientes com diagnóstico de LES e que fizeram tratamento com CFM com seguimento clínico de, pelo menos, 1 ano. Foram incluídas pacientes com idade entre 12 e 40 anos e que apresentavam ciclos menstruais regulares prévios ao tratamento. Foram excluídas pacientes que descontinuaram o seguimento, ou este foi menor do que um ano, além daquelas que apresentaram irregularidade/ausência menstrual antes do uso do fármaco. Todas as mulheres estudadas foram submetidas à entrevista e à aplicação de questionário. Neste foram abordadas questões relevantes de padrão de ciclo menstrual antes e posterior à terapia, assim como períodos gestacionais e método contraceptivo. Foi questionado se as pacientes foram orientadas sobre os efeitos colaterais e as consequências da CFM. Para análise estatística, foram utilizados os testes t de Student, Mann-Whitney, do χ2 e o não paramétrico de Kolmogorov-Smirnov. RESULTADOS: A média de idade das pacientes incluídas no do estudo foi de 30,8 anos, e a média de idade no momento do uso de CFM, de 25,3 anos. Após a CFM, 24% das pacientes não menstruaram mais, 28% voltaram a ter ciclos regulares e 48% delas permaneceram com ciclos irregulares. Verificou-se que as pacientes que evoluíram com falência ovariana tinham maior tempo de doença (12,3 anos) do que aquelas que não evoluíram (8,9 anos). Treze pacientes tiveram gestação após a CFM, em todas ocorreu de forma espontânea; no entanto, 66% evoluíram com abortamento. A média de idade das pacientes que fizeram uso de CFM e evoluíram com falência ovariana foi de 28,1 anos. A amenorreia ocorreu em 50% das pacientes ...


PURPOSE: To evaluate the ovarian response after cyclophosphamide use (CPM) in patients with systemic lupus erythematosus (SLE) and to correlate the age and cumulative dose findings with changes in menstrual cycle and/or progression to ovarian failure (OF). METHODS: This was a cross-sectional, retrospective study of 50 patients with a diagnosis of SLE who used CFM with a clinical follow-up of at least 1 year. Included were patients aged 12-40 years, who had undergone chemotherapy for SLE control and who had regular menstrual cycles before the beginning of CPM treatment. Patients who discontinued follow-up, who were followed up for less than one year or who had irregular/absent menses before the beginning of CPM treatment were excluded. All women studied were submitted to an interview and a questionnaire containing questions about the pattern of the menstrual cycle before and after therapy, and about the gestational periods and contraception. We asked if the patients had been instructed about the side effects and consequences of CFM. Statistical analysis was performed using the Student t-test and the Mann Whitney, χ2 and nonparametric Kolmogorov-Smirnov tests. RESULTS: The mean age of the patients included in the study was 30.8 years and the mean age at the time of use of CPM was 25.3 years. After CFM, 24% of patients stopped menstruating, 28% returned to regular cycles and 48% continued to have irregular cycles. It was found that the patients who developed OF had longer disease duration (12.3 years) than those who did not develop it (8.9 years). Thirteen patients became spontaneously pregnant after CFM; however, 66% progressed to abortion. The mean age of the patients who used CFM and developed OF was 28.1 years. Amenorrhea occurred in 50% of those aged 31-40 years, in 22.2% of those aged 21-30 years and in 7.7% of those aged 12-20 years. Our study showed no statistical correlation between cumulative dose and OF, although cumulative ...
