Relaxin en placenta -volume in placenta accreta spectrum
Evaluatie van relaxine en placenta-volume in placenta accreta spectrumstoornissen: een case-control-studie
This retrospective case-control study investigated the potential role of circulating relaxin levels and estimated placental volumes (EPV) in the pathogenesis and diagnosis of placenta accreta spectrum (PAS) disorders. It compared these parameters in patients diagnosed with PAS versus healthy controls.

Gedetailleerde beschrijving
This study aimed to compare relaxin levels in umbilical cord and peripheral blood and estimated placental volumes (EPV) between PAS cases and controls. Additionally, subgroup analysis was conducted to evaluate relaxin levels and EPV among PAS subtypes (accreta, increta, and percreta).A retrospective case-control study was conducted at a tertiary referral center, analyzing data from January 2022 to December 2022.

Studie Bevolking
The study population consisted of two groups. Following retrospective investigation of patients operated in our clinic between 01.01.2022 and 01.12.2022, the case group included 20 patients diagnosed with PAS disorders, suspected with clinical and imaging findings, confirmed through histopathological findings. These patients had undergone elective cesarean hysterectomy and met inclusion criteria aged between 18 and 45 years and availability of complete medical records. Due to ethical considerations, 4 patients diagnosed with PAS who underwent emergency surgery because of vaginal bleeding and 14 patients operated with segmentary resections were excluded from the study to compose more homogenous study cohort for the measurement of EPV. The control group consisted of 20 healthy pregnant women who underwent the first planned cesarean section of the day, without any obstetric complications, on the same days when planned PAS cesarean-hysterectomy cases were performed in 2022.

The primary source of relaxin in pregnancy is the corpus luteum, but it is also produced in other tissues, such as the decidua and placenta. Importantly, relaxin's pleiotropic effects include endothelial-dependent vasodilation, extracellular matrix remodeling, and potential contributions to placental development. These properties make relaxin a molecule of interest in the context of PAS disorders, where abnormal placental invasion may reflect disruptions in vascular and extracellular matrix regulation. Additionally, recent findings have indicated altCirculating relaxin levels were assessed before routinely storing maternal venous blood and umbilical cord arterial blood samples are anelyzed. This study aimed to compare relaxin levels in umbilical cord and peripheral blood and estimated placental volumes (EPV) between PAS cases and controls. Additionally, subgroup analysis was conducted to evaluate relaxin levels and EPV among PAS subtypes (accreta, increta, and percreta). |

The primary source of relaxin in pregnancy is the corpus luteum, but it is also produced in other tissues, such as the decidua and placenta. Importantly, relaxin's pleiotropic effects include endothelial-dependent vasodilation, extracellular matrix remodeling, and potential contributions to placental development. These properties make relaxin a molecule of interest in the context of PAS disorders, where abnormal placental invasion may reflect disruptions in vascular and extracellular matrix regulation. Additionally, recent findings have indicated altered expression of relaxin, its receptor RXFP1, and insulin-like peptide 4 (INSL4) in PAS cases, suggesting potential roles in its pathogenesis. |

placental volume
Tijdsspanne: 11 months
|
Placental volume, assessed through imaging modalities, has been explored as a potential biomarker for abnormal placental development, including PAS. Studies have demonstrated that larger placental volumes may be associated with invasive placentation, suggesting a correlation between placental growth patterns and PAS severity. |
