- Acute splenic sequestration in a pregnant woman with homozygous sickle-cell anemia(2013) MAIA, Carolina Bastos; NOMURA, Roseli Mieko Yamamoto; IGAI, Ana Maria Kondo; FONSECA, Guilherme Hencklain; GUALANDRO, Sandra Menosi; ZUGAIB, MarceloCONTEXT: Homozygous (SS) sickle-cell anemia complicated by acute splenic sequestration in adults is a rare event, and it has never been reported during pregnancy. CASE REPORT: A 25-year-old woman with homozygous (SS) sickle-cell disease was hospitalized at 32 weeks' of gestation presenting weakness, abdominal pain, fever and hemoglobin of 2.4 g/dl. Abnormal fetal heart rate was detected by means of cardiotocography, and 5 units of packed red cells were transfused. Cesarean was performed at 37 weeks. Both mother and baby were discharged in a good general condition. CONCLUSION: This case report demonstrates the importance of immediate blood transfusion for treatment of fetal distress in cases of splenic sequestration during pregnancy. This treatment is essential for avoiding maternal and fetal complications.
- Anemia During Pregnancy after Silastic Ring Roux-en-Y Gastric Bypass: Influence of Time to Conception(2011) NOMURA, Roseli Mieko Yamamoto; DIAS, Maria Carolina Goncalves; IGAI, Ana Maria Kondo; PAIVA, Leticia Vieira; ZUGAIB, MarceloBariatric surgery before pregnancy may help prevent obesity-related gestational complications. However, maternal malnutrition is not without potential risks during pregnancy. The objective was to evaluate the influence of time to conception after silastic ring Roux-en-Y gastric bypass (SRYGB) on maternal anemia. Patients who underwent SRYGB for morbid obesity and who subsequently became pregnant were followed up at the prenatal. Thirty pregnancies occurred between July 2001 and September 2009. The patients were analyzed according to time to conception after bariatric surgery: 17 patients with time to conception < 4 years (48 months) and 13 patients with a parts per thousand yen4 years. First trimester hemoglobin levels were significantly lower in patients with time to conception a parts per thousand yen4 years (48 months) (median 9.6 g/dL, range 5.8-13.2 g/dL) than in patients with time to conception < 4 years (median 11.1 g/dL, range 9.8-13.6 g/dL; p = 0.047). The need for intravenous iron therapy or packed red cell transfusion was significantly more frequent among women who became pregnant a parts per thousand yen4 years after SRYGB compared to < 4 years (30.8% vs. 0%, p = 0.026). Pregnancy after 4 years of SRYGB is associated with maternal anemia and the need for more strict iron supplementation.
- Manejo clínico e obstétrico em gestantes portadoras de hepatite autoimune complicada pela plaquetopenia moderada ou grave(2013) NOMURA, Roseli Mieko Yamamoto; KLEINE, Roololpho Truffa; IGAI, Ana Maria Kondo; FRANCISCO, Rossana Pulcineli Vieira; ZUGAIB, MarceloObjective: To describe the management of prenatal care and delivery in patients bearing autoimmune hepatitis associated with moderate or severe thrombocytopenia. Methods: This study was performed in a tertiary level university hospital. Thirteen pregnancies in ten patients diagnosed with autoimmune hepatitis, complicated by thrombocytopenia, were retrospectively analyzed. The inclusion criteria were as follows: clinical diagnosis of autoimmune hepatitis, moderate or severe thrombocytopenia (platelet count < 100 x 103/mm(3)), gestational age at birth over 22 weeks, and patient followed-up by a specialized team at the institution. The variables studied were: maternal age, parity, treatment regimen, platelet count, examinations for investigation of hepatic function, type of delivery, weight at birth, and gestational age at the time of delivery. Results: The average maternal age was 24.5 years (SD = 5.3) and six (50%) occurred in nulliparous women. During pregnancy, monotherapy with prednisone was adopted in 11 cases (92%). According to the autoantibody profiles, seven pregnancies (58%) had the autoimmune hepatitis type I diagnosis, two pregnancies had type II (17%), and three pregnancies (25%) had cryptogenic chronic hepatitis (undetectable titers of autoantibodies). Portal hypertension was featured in 11 pregnancies (92%). The average gestational age at delivery was 36.9 weeks (SD = 1.5 weeks), with an average weight at birth of 2,446 g (SD = 655 g). Eight infants (67%) were small for gestational age. At the time of delivery, severe thrombocytopenia was featured in four cases (33%) and cesarean surgery was performed in seven cases (58%). Complications at delivery occurred in three cases (25%), one patient presented uterine atony, and two patients presented perineal bruising. There was no perinatal or maternal death. Conclusion: The complication's of thrombocytopenic patients with autoimmune hepatitis are elevated; nevertheless, with appropriate attention and care, they can be resolved. The association between two severe pathologies appears to increase the risk of prematurity and fetal growth restriction, demanding specialized prenatal care, as well as surveillance of newborn well-being.
- Maternal malnutrition during pregnancy among women with sickle cell disease(2023) PAIVA, Leticia Vieira; IGAI, Ana Maria Kondo; NOMURA, Roseli Mieko YamamotoOBJECTIVE: The objective of this study was to compare the nutritional status and dietary intake of pregnant women with sickle cell disease (SS hemoglobinopathy and SC hemoglobinopathy) to healthy controls and report the maternal and perinatal outcomes.METHODS: This is a prospective, longitudinal cohort study. Pregnant women with a diagnosis of sickle cell disease and control group were recruited in an outpatient clinic of a tertiary care hospital in Sao Paulo, Brazil. Maternal anthropometric data and dietary intake data were collected at the second and third trimesters.RESULTS: A total of 49 pregnancies complicated by sickle cell disease were included. Prepregnancy body mass index was significantly lower in the SS hemoglobinopathy group (n=26, median 20.3 kg/m(2)) than the SC hemoglobinopathy group (n=23, 22.7 kg/m(2)) or control group (n=33, 23.2 kg/ m(2), p<0.05). The prepregnancy nutritional status revealed significantly more women classified as underweight in the SS hemoglobinopathy group (15.4%) than in the SC hemoglobinopathy group (4.4%) and control group (1.6%, p=0.009). In the second trimester, maternal protein intake was significantly lower in SS hemoglobinopathy (73.2 g/day) and SC hemoglobinopathy (68.8 g/day) than in the control group (95.7 g/day, p=0.004). In the third trimester, only SS hemoglobinopathy mothers showed dietary intake of protein significantly lower than that of the controls (67.5 g/day vs. 92.8 g/day, p=0.02). Vitamin A and E consumption was also reduced in the third trimester in the SS hemoglobinopathy group (p<0.05).CONCLUSION: The nutritional status of pregnant women with SS hemoglobinopathy is characterized by a state of undernutrition. The lower protein intake in the second and third trimesters of pregnant women with SS hemoglobinopathy may contribute to this condition. Undernourishment is a serious complication of sickle cell disease, primarily during pregnancy, and it should be addressed during the prenatal period.
