AI Article Synopsis
- * Data were collected from 3307 women with singleton pregnancies who underwent the procedure between 2007 and 2012, revealing a very low total pregnancy loss rate of 0.2% within 4 weeks post-testing.
- * Advanced maternal age was the primary reason for amniocentesis, and the study identified various risk factors for fetal loss, making it important for patient counseling prior to the procedure.
Article Abstract
Objective: To determine the short-term outcomes of second-trimester genetic amniocentesis at Siriraj Hospital, Bangkok, Thailand.
Methods: In a retrospective descriptive study, data were assessed from women with a singleton pregnancy who underwent genetic amniocentesis between 16 and 21 gestational weeks at the Division of Maternal Fetal Medicine, Department of Obstetrics and Gynecology, Siriraj Hospital, from May 2007 to June 2012. The amniocentesis records and medical data of all women were analyzed statistically.
Results: During the 5-year period, complete data were collected for 3307 pregnant women. The rate of total pregnancy loss within 4 weeks of testing was 7 out of 3307 (0.2%; 95% confidence interval, 0.1%-0.4%). Advanced maternal age (≥35 years) was the most common indication for amniocentesis (94.6%). The culture failure rate was 0.2%. Chromosomal abnormalities were detected in 109 pregnancies (3.3%); trisomy 21 was the most prevalent abnormality (0.8%). The possible risk factors of fetal loss were early amniocentesis (gestational age, <18 weeks) (P=0.013), abnormal fetal sonography (P=0.004), culture failure (P=0.015), and old-blood- or murky-stained amniotic fluid (P=0.036).
Conclusion: Second-trimester genetic amniocentesis resulted in 0.2% of total pregnancy loss within 4 weeks of testing. This information is essential for patient counseling before amniocentesis.

Objective: Ichthyosis are complex skin diseases, characterized by hyperkeratosis with various degrees of thickening, desquamation, and erythema. The prenatal diagnosis of ichthyosis is challenged due to the clinical and genetic heterogeneity and the late-onset of fetal features on ultrasound scan. Here, we reported two fetuses with Harlequin ichthyosis (HI), a severe subtype of autosomal recessive congenital ichthyosis (ARCI), who were diagnosed prenatally by images and genetic investigations.

Purpose: Severe combined immunodeficiency (SCID) is a set of rare monogenic inherited diseases that together represent the most severe form of the primary immunodeficiency disease phenotype. Preimplantation genetic testing for monogenic defects (PGT-M) is an effective reproductive technology strategy to prevent disease-causing gene mutations from being transmitted to offspring. The aim of this study was to report the use of PGT-M strategy based on karyomapping in four families to avoid the birth of SCID children.

Alloimmunization during pregnancy occurs when a mother produces antibodies against fetal antigens, leading to complications like hemolytic disease of the fetus and newborn (HDFN) and fetal and neonatal alloimmune thrombocytopenia (FNAIT). HDFN involves destruction of fetal red blood cells, potentially causing severe anemia, hydrops fetalis, and fetal death. FNAIT affects fetal platelets and possibly endothelial cells, resulting in risk of intracranial hemorrhage and brain damage.
