ABSTRACT

SUMMARY OBJECTIVE: The aim of this study was to investigate the relationship between Chitinase 3-Like 1 gene polymorphisms and the occurrence of preeclampsia in a selected cohort of pregnant women. METHODS: A total of 75 pregnant women participated in the study, 35 of whom were diagnosed with preeclampsia, while 40 served as healthy controls. The preeclamptic group was subdivided based on severity. Real-time polymerase chain reaction was employed to analyze the serum samples for variations in Chitinase 3-Like 1 gene polymorphisms. RESULTS: The rs880633 polymorphism was found to be significantly more frequent in the control group (80%) compared with the overall preeclamptic group (60%) (p<0.05). In the severity-based subgroups, rs880633 appeared in 57.1% of non-severe and 61.9% of severe preeclamptics. Contrarily, the heterozygous form of rs7515776 polymorphism showed a significantly higher prevalence in the preeclamptic cohort (p<0.05), without distinctions in severity subgroups. CONCLUSION: The study suggests that the rs880633 polymorphism may serve a protective role against the development of preeclampsia, whereas the rs7515776 polymorphism may be associated with an elevated risk. Further research is warranted to elucidate the clinical implications of these findings.

ABSTRACT

SUMMARY OBJECTIVE: We aimed to compare the etiology and perinatal outcomes of non-immune hydrops fetalis diagnosed early- and late-onset at our hospital. METHODS: The records of the patients who applied to our department were reviewed, and we reached 42 non-immune hydrops fetalis cases retrospectively and examined the medical records. Hydrops diagnosis week, birth week, accompanying anomalies, and perinatal outcomes were compared as ≤12 weeks (early-onset) and >12 weeks (late-onset). RESULTS: The prevalence of non-immune hydrops fetalis was 0.05%, and the median week of diagnosis for hydrops was 18 weeks. Consanguinity (16.7%) was found in seven pregnancies, and the other seven patients (16.7%) had a history of hydrops in previous pregnancies. Anomalies of the skeletal system, central nervous system, and gastrointestinal tract accounted for 66.7% of ≤12 weeks in non-immune hydrops fetalis cases. Cardiac abnormalities were more common (26.7%) in patients at > 12 weeks (p=0.078). A statistically significant difference was found between the distribution of week of birth and week of diagnosis (p=0.029). Notably, 66.7% of patients diagnosed before week 12 and 23.3% of patients diagnosed after week 12 delivered their babies before week 24. Spontaneous intrauterine death occurred before week 12 in 45.5% (n=5) of non-immune hydrops fetalis and after week 12 in 39.1% (n=9) of non-immune hydrops fetalis. Notably, 69.2% (n=9) of the patients who had prenatal invasive testing resulted in normal karyotype. CONCLUSION: In this study, most of the fetuses diagnosed with early-onset non-immune hydrops fetalis were born in the first 24 weeks. Additionally, live birth rates and cardiac anomalies were observed to be higher in late-onset non-immune hydrops fetalis.

ABSTRACT

Abstract Objective We evaluated risk factors to determine if there were specific risk factors that could predict massive bleeding in nulliparous women with placenta previa. Methods The participants were classified into two groups. Women with a calculated blood loss ≥ 1,000mL were included in the massive bleeding group. Women without any signs or symptoms related with hypovolemia or with a calculated bleeding volume < 1,000 mL were categorized into the non-massive bleeding group. Results There were 28 patients (40.6%) with massive bleeding and 41 cases (59.4%) with non-massive bleeding. The calculated blood loss and number of cases that required red cell transfusions were statistically different between the groups (< 0.005 and 0.002, respectively). There were no statistically significant differences in terms of maternal or fetal factors, placental location, or delivery characteristics between the two groups. Conclusion We could not determine the predictive features for massive hemorrhage based on clinical features, delivery features, or placental location.

ABSTRACT

Abstract Objective To evaluate the outcomes of cases of prenatally-diagnosed congenital pulmonary airway malformation (CPAM). Methods We retrospectively evaluated cases of prenatally-diagnosed CPAM between 2004 and 2018. Ultrasonographic features such as visualization of a fetal lung mass and heterogeneous pulmonary parenchyma were used for CPAM diagnosis. Prenatal and postnatal findings were compared in terms of accuracy regarding the CPAM diagnosis. Results The sample consisted of 27 cases. There were four cases in which the patients opted for the termination of pregnancy due to the severity of the lesion. A total of 23 neonates were delivered, and CPAM was confirmed in 15 cases. Themedian gestational age at delivery was 37 weeks (28-40 weeks) and the mean birth weight was 2,776 g. There were two neonatal deaths, one due to pneumothorax, and the other due to hypoplastic left heart syndrome (HLHS). A total of five patients with respiratory problems were operated in the postpartum period. There were eight misdiagnosis: bronchopulmonary sequestration (five cases), congenital lobar emphysema (two cases), and congenital diaphragm hernia (one case). Conclusion A precise postnatal diagnosis is very important to organize the proper management of the pregnancies with fetuses with CPAM. The positive predictive value of the prenatal diagnosis of CPAM via ultrasonography is of 70.3%. The differential diagnosis of CPAM may be prolonged to the postpartum period in some cases.

ABSTRACT

ABSTRACT Objective: This study aims to give information about the relationship between different types of factor deficiencies and maternal/obstetric outcomes. Methods We retrospectively reviewed the medical records of eight women with factor deficiency disorders. The demographic and clinical features of the patients after their last pregnancies were registered retrospectively. Results: There were 29 pregnancies among the 8 patients. The spontaneous abortion rate was relatively high in two patients with factor XIII deficiency (80% and 57.1%) compared with the other factor deficiency groups. There were 16 births, which included 1 set of twins, and 2 deaths (1 stillbirth and 1 postpartum exitus occurred in the same patient). Intrauterine growth restriction was noted in five cases; four of these occurred in factor X deficiency cases. The mean decrease in hemoglobin level of all patients after birth was 1.7 g/dL (range, 0.2-3.6 g/dL). Red blood cell transfusion was required only in one case of factor XIII deficiency. Conclusions: There is currently no consensus on the pregnancy management of women with factor deficiencies because of the limited knowledge due to the rarity of such disorders. Labor should be managed in a dedicated unit with a team consisting of an obstetrician, a hematologist, an anesthesiologist, a midwife, and a pediatrician to minimalize the complications.


RESUMO Objetivo: O presente estudo objetiva fornecer informações sobre a relação entre diferentes tipos de deficiências de fator e resultados obstétricos e maternais. Métodos Análise retrospectiva de registros médicos de oito mulheres com deficiências de fator. Dados demográficos e clínicos das pacientes após sua última gestação foram obtidos. Resultados: Vinte e nove gestações ocorreram entre as oito pacientes. As taxas de abortos espontâneos foram relativamente altas em duas pacientes com deficiência de fator XIII (80% e 57,1%) se comparadas aos demais grupos de deficiências de fator. Ocorreram dezesseis nascimentos, sendo que um deles foi o de um par de gêmeos, e dois óbitos (um natimorto e um pós-parto na mesma paciente). Restrição de crescimento intrauterino foi identificada em cinco casos, sendo quatro destes com deficiência de fator X. A principal baixa em nível de hemoglobina entre todas as pacientes após o parto foi de 1,7 g/dL (variação, 0,2-3,6 g/dL). Transfusão de hemácias foi necessária apenas em um caso com deficiência de fator XIII. Conclusão: Não há consenso atualmente para o manejo de gestantes com deficiências de fator em função do conhecimento limitado, dada a raridade de tais condições. O parto deve ocorrer em uma unidade específica com uma equipe composta de obstetra, hematologista, anestesista, parteira, e pediatra para minimizar as complicações
