RESUMO
Endometriosis (EM) is a gynecological disorder that presents significant immune dysregulation in its pathophysiology. Recent studies indicate that the Complement System may play a significant role in the immune processes involved in peritoneal clearance and inflammation in EM patients. C5a is a potent anaphylatoxin molecule of complement associated with the development of inflammatory disorders, however its possible impact on EM development requires further investigation. The aim of this study was to determine the concentration of serum C5a in women with EM and to investigate its possible association with severity, symptoms, age and the timing of infertility. Ninety-four patients with EM (from stage I to IV) and 50 healthy controls were assessed for C5a serum levels. Clinical and demographic data were included in the analysis. C5a serum levels were higher in patients with EM than in controls (39.5 ng/mL vs. 26.0 ng/mL; p < .0001), but not different between the EM stages. No association was observed between C5a serum concentration and the presence of symptoms, age, symptom time or infertility time. The C5a serum levels were higher in patients with EM than in controls but not associated with the severity or clinical findings.

Markers of autoimmunity, such as autoantibodies, have been found in patients with endometriosis. These include the antinuclear antibodies (ANA). We aimed to evaluate the prevalence of ANA in a sample of patients with endometriosis and its possible clinical associations. Ninety-four patients with endometriosis and 91 controls were studied for ANA and extractable nuclear antigen (ENA; anti-Ro, anti-La, anti-Sm, and anti-RNP) profiles and anti-dsDNA. Epidemiological, clinical, and staging data in endometriosis were obtained. Patients with autoimmune disorders were excluded. Patients with endometriosis had a 21.2% prevalence of positive ANA vs. 5.4% in controls (P = 0.001). The ENA profile and anti-dsDNA were negative. Patients with positive ANA were more asymptomatic (P = 0.03) and had less dysmenorrhea. No associations with disease duration, patient age, or endometriosis stage were found. We found a high prevalence of positive ANA in patients with endometriosis. The presence of this autoantibody may be linked to a milder clinical expression of the disease.

A endometriose é condição ginecológica crônica, caracterizada pela presença de tecido semelhante ao endométrio fora da cavidade uterina. Apesar da causa ser complexa e pouco elucidada, estudos sugerem fortes associações entre endometriose e anormalidades no sistema imunológico. Assim é importante determinar a prevalência de fator anti nuclear (FAN) e anti-DNA em pacientes diagnosticadas com endometriose e suas associações. Foi realizado estudo transversal analítico para elucidar o tema. A amostra foi composta por 94 pacientes com diagnóstico de endometriose confirmado por videolaparoscopia e biópsia com estudo anatomopatológico. Como grupo controle foram utilizados 91 pacientes pareados em idade e gênero. Em conclusão, pacientes com endometriose apresentam maior prevalência de FAN em relação ao grupo controle. A positividade do FAN não tem associação com o estadiamento ASRM da endometriose e gravidade da doença. As pacientes com endometriose não apresentaram reatividade para o anticorpo anti-ds-DNA.
Endometriosis is a chronic gynecological condition, characterized by the presence of tissue similar to the endometrium outside the uterine cavity. Although the etiology is complex and poorly understood, studies suggest strong associations between endometriosis and abnormalities in the immune system. Thus, it is important to determine the prevalence of anti-nuclear factor (ANA) and anti-DNA in patients diagnosed with endometriosis and their associations. An analytical cross-sectional study was carried out to elucidate the topic. The sample consisted of 94 patients with a diagnosis of endometriosis confirmed by videolaparoscopy and biopsy with anatomopathological study. As a control group, 91 patients matched for age and gender were used. In conclusion, patients with endometriosis have a higher prevalence of ANA compared to the control group. ANA positivity is not associated with ASRM staging of endometriosis and disease severity. Patients with endometriosis did not show reactivity to anti-ds-DNA antibody.
