O objetivo do estudo foi diagnosticar e tratar as gestantes diabéticas com anticorpos presentes e descrever os resultados gestacionais e perinatais. Foram analisadas 56 gestantes diabéticas que deram entrada no Pré-Natal Especializado do CAISM/Unicamp, entre julho de 2003 a março de 2004. Todas as que aceitavam participar do estudo foram submetidas à coleta de sangue para dosagem de anticorpos antifosfolípides (anticoagulante lúpico e anticorpo anticardiolipina). Se um ou outro anticorpo estivesse presente, a gestante seria tratada com AAS e Heparina. Foram caracterizados os perfis da gestante, da evolução da gestação e do recém-nascido. Foram diagnosticados anticorpos antifosfolípides em 7% das 56 gestantes e os resultados gestacionais e perinatais foram descritos. Nas gestantes diabéticas com anticorpos antifosfolípides a duração do diabetes foi de cinco em uma das gestante e dez anos nas outras três gestantes. A idade variou entre 27 e 38 anos e uma das gestantes era primigesta, outra secundigesta e as outras duas multíparas. As gestantes com anticorpos antifosfolípides, que foram tratadas, tiveram resultados gestacional e perinatal satisfatórios / Abstract: The prevalence of antiphospholipid antibodies in pregnant women with pre-gestational diabetes is high, causing gestational and perinatal alterations. The purpose of this study was to diagnose and treat diabetic pregnant women with presence of antibodies and describe the gestational and perinatal results. An analysis was made of 56 diabetic pregnant women who enrolled in the pre-natal specialization at CAISM/UNICAMP, between July, 2003 and March, 2004. All the diabetic pregnant women who agreed to participate in the study had blood collected for antiphospholipid antibody dosage (lupus anticoagulant and anticardiolipin antibody). If any other antibodies were present, the pregnant woman would be treated with Aspirin and Heparin. The following data with reference to the pregnant woman were recorded: age, gestational age, time of diabetes mellitus duration, treatment prior to and during gestation, previous illnesses, hypertension in pregnancy, amniotic liquid index, parturition, way of giving birth, Apgar index, fetal malformation, fetal hypoglycemia and birth weight. Antiphospholipid antibodies were diagnosed in 7% of the 56 pregnant women and their gestational and perinatal results were described. In the diabetic pregnant women with antiphospholipid antibodies, the duration of the diabetes was from five to ten years, that is to say, pregnant women with long-standing diabetes. The pregnant women with antiphospholipid antibodies ranged from 27 to 38 years of age, and some of the descriptions indicated that they had gone through a bad obstetric experience. The pregnant women with antiphospholipid antibodies, who were treated, had satisfactory gestational and perinatal results / Mestrado / Tocoginecologia / Mestre em Tocoginecologia

Objetivo: avaliar associação dos antecedentes mórbidos, da Dopplervelocimetria de artérias uterinas, dos anticorpos antifosfolipídeos (AAF) e resultados obstétricos/perinatais em um grupo de gestantes. Sujeitos e Métodos: foi conduzido um estudo de coorte e corte transversal, onde foram analisadas gestantes atendidas nos Ambulatórios de Pré-Natal da Unicamp que aceitaram participar do estudo. Foi aplicado um questionário sobre os antecedentes mórbidos, realização de dosagem dos AAF, realizada Dopplervelocimetria de artérias uterinas e analisada correlação com resultados obstétricos/perinatais. Resultado: foram avaliadas 385 gestantes com média de idade de 26,6 (±6,3) anos. A anticardiolipina (aCL) e o anti-ß2 glicoproteína I (anti-ß2-gpI) foram avaliados em 382 gestantes, dos quais 4,4% apresentaram o anti-ß2gpI IgM positivo, 4,7% IgG, 6,2% aCL IgG e 6,7% IgM. O anticoagulante lúpico (AL) foi avaliado em 137 gestantes com positividade em 2,3%. 33,4% das gestantes tinham, pelo menos, um antecedente obstétrico desfavorável (aborto recorrente, óbito fetal, pré-eclâmpsia, parto prematuro, filho anterior nascido com peso menor que 2.500g ou descolamento prematuro de placenta) e 2,6% tinham eventos trombóticos (infarto, acidente vascular cerebral, tromboembolismo pulmonar ou trombose venosa profunda). 16,5% tinham pelo menos um antecedente e um AAF positivo, contra 13,3% sem antecedente (p=0,44). 10% apresentavam antecedente trombótico e AAF positivo contra 14,4% sem história de evento trombótico e AAF negativo (p=0,88). As complicações obstétricas/perinatais foram avaliadas em 305 gestantes sendo que no grupo com antecedentes 31,7% evoluíram para alguma complicação obstétrica na gestação em curso contra 28,4% do grupo sem antecedente (p=0,59). Analisando o desfecho pré-eclâmpsia com pelo menos um antecedente, 7,7% x 4,5% (p=0,29), índice Apgar no 5º minuto menor ou igual a 7, 4,9% x 5,6% (p=0,57), peso abaixo de 2.500g, 15,5% x 12% (p=0,47). Quando separados os grupos com e sem antecedentes e comparados ao Doppler de artérias uterinas as mulheres que relataram peso inferior a 2.500g tiveram 4,0 [IC95: 1,16-13,7] vezes mais chance de apresentar índice de pulsatilidade acima do percentil 95 (IP>P95) e 4,68 [IC95: 1,37-15,9] quando apresentavam antecedente de elevação da pressão arterial antes das 34 semanas em gestação anterior. Não foram encontradas correlações dos outros antecedentes com o Doppler. Quando o IP>P95 houve um risco relativo (RR) de 2,77 [IC95: 1,87-4,11] para pelo menos uma complicação obstétrica/perinatal, 5,19 [IC95: 1,41-19,1] para Apgar do 5º minuto menor que 7 e 6,94 [IC95: 4,31-11,1] de peso abaixo de 2.500g. Quando associado IP>P95 e pelo menos um antecedente o RR para peso abaixo de 2.500g foi de 6,06 [IC95: 3,19-11,5] e 6,61 [IC95: 3,46-12,6] para parto antes das 37 semanas. Quando comparados os dois grupos não foi encontrada significância estatística no desfecho de pré-eclâmpsia com RR de 4.70 [IC95: 0,80-27,4]. Na avaliação do IP>P95 e AAF, 11,1% tinham o IP>P95 e pelo menos um AAF, contra 14,4% no grupo sem essas características, com Razão de Prevalência (RP)=0,77 [IC95: 0,11-4,96]. A RP para o grupo com IP>P95 e pelo menos um antecedente para a presença de pelo menos um AAF, foi de 1,75 [IC95: 0,31-9,75]. Conclusão: os antecedentes obstétricos desfavoráveis, assim como o Doppler de artérias uterinas não se correlacionaram com os AAF. O aumento da resistência ao Doppler nas artérias uterinas, isoladamente ou em associação aos antecedentes mórbidos, apresentou maior chance de complicações obstétricas/perinatais. Não foram encontradas diferenças estatísticas quando avaliado o Doppler associado com antecedentes e AAF / Abstract: The presence of antiphospholipid antibodies is often associated with obstetrical complications such as recurrent miscarriage, fetal death, placental abruption and severe early preeclampsia. Objective: To evaluate the association between a history of morbidity, uterine artery Doppler flow, serum antiphospholipid antibodies (APA) and perinatal/obstetric outcomes in a group of pregnant women. Subjects and methods: A cross-sectional cohort study evaluated pregnant women receiving care at Unicamp's prenatal clinic, who agreed to participate in the study. A questionnaire was applied to obtain data on the patient's history of morbidity, serum antiphospholipid antibodies were measured and a Doppler scan of the uterine arteries was performed. Results were correlated with obstetrical/perinatal outcome. Results: A total of 385 pregnant women with a mean age of 26.6 ± 6.3 years were evaluated. Anticardiolipin (aCL) and anti-ß2 glycoprotein I (anti-ß2-gpI) were evaluated in a group of 382 pregnant women, 4.4% of whom tested positive for anti-ß2-gpI IgM, 4.7% for IgG, 6.2% for ACL IgG and 6.7% for IgM. Lupus anticoagulant (LA) was evaluated in 137 pregnant women, 2.3% of whom tested positive. Overall, 33.4% of patients had a medical history that included recurrent miscarriage, fetal death, preeclampsia, prematurity, previous pregnancy resulting in an infant with birthweight of <2.500g or placental abruption. In addition, 2.6% had experienced a thrombotic event such as myocardial infarction, stroke, pulmonary thromboembolism or deep vein thrombosis. Overall, 16.5% of patients had at least one of the above-mentioned conditions and tested positive for APA compared to 13.3% of those with no medical history of any of these conditions (p=0.44). Ten percent of the women had experienced a thrombotic event and tested positive for APA while 14.4% had never had a thrombotic event and tested negative for APA (p=0.88). Obstetric and perinatal outcomes were analyzed in 305 women, and results showed that 31.7% of the women with a medical history of morbidities suffered at least one obstetrical complication in the current pregnancy compared to 28.4% in the group of women who had no medical history of morbidity (p=0.59). When each outcome was correlated with a history of at least one medical condition, preeclampsia was found in 7.7% of cases versus 4.5% in the group with no medical history (p=0.29), 5th minute Apgar score = 7 in 4.9% compared to 5.6% (p=0.57) and birthweight <2.500g in 15.5% compared to 12% (p=0.47). When the groups of women with and without a medical history of complication were analyzed separately and correlated with uterine artery Doppler, the women who reported having had an infant with a birthweight <2.500 grams were four times more likely (95%CI: 1.16-13.7) to have a pulsatility index (PI) above the 95th percentile and 4.68 times more likely (95%CI: 1.37-15.9) if they had a history of increased blood pressure prior to 34 weeks in their previous pregnancy. No significant correlations were found between other medical conditions and PI above the 95th percentile. When the PI was above the 95th percentile, there was a relative risk (RR) of 2.77 (95%CI: 1.87-4.11) of developing at least one obstetrical/perinatal complication, a RR of 5.19 (95%CI: 1.41-19.1) of 5th minute Apgar score being = 7 and a RR of 6.94 (95%CI: 4.31-11.1) of birthweight <2.500 grams. When PI above the 95th percentile was associated with at least one prior complication, the RR for birthweight <2.500 grams was 6.06 (95%CI: 3.19 - 11.5) and 6.61 (95%CI: 3.46 - 12.6) for delivery prior to 37 weeks. When the two groups were compared, no statistically significant correlation was found with respect to eclampsia (RR 4.70; 95%CI: 0.80 - 27.4). In the evaluation of PI above the 95th percentile and APA, 11.1% of patients had PI above the 95th percentile and at least one APA compared to 14.4% in the group without these characteristics (prevalence ratio [PR] 0.77; 95%CI: 0.11-4.96). The PR for the group with PI above the 95th percentile and at least one previous medical condition was 1.75 (95%CI: 0.31-9.75). Conclusion: Neither history of morbidity nor uterine artery Doppler was found to be associated with antiphospholipid antibodies. A significant correlation was found between increased uterine artery Doppler resistance, both when analyzed alone or in association with medical history, and obstetric/perinatal complications. No statistically significant differences were found between uterine artery Doppler associated with medical history and antiphospholipid antibodies / Doutorado / Tocoginecologia / Doutor em Tocoginecologia
