Laparoscopic adenomyomectomy combined with levonorgestrel-releasing intrauterine system is effective for long-term management of adenomyosis

BACKGROUD

Laparoscopic adenomyomectomy combined with intraoperative placement of levonorgestrel-releasing intrauterine device (LNG-IUS) is a novel conservative surgical procedure for adenomyosis. Our study aimed to compare the efficacy of surgery with or without intraoperative placement of LNG-IUS treatment in adenomyosis.

METHODS

We retrospectively reviewed the medical records of adenomyosis patients who received laparoscopic adenomyomectomy from January 2014 to April 2020, finally including 70 patients undergoing surgery-LNG-IUS as group A and 69 patients undegoing surgery only as group B. Risk factors for three-year relapse were analyzed using Cox's multivariate proportional hazard analysis.

RESULTS

Visual analog scale and Mansfield-Voda-Jorgensen Menstrual Bleeding Scale scores of group A at 3, 6, 12, 24, and 36 months were significantly lower than those of group B at the corresponding points (P < .001 for both scales). Individuals in both groups showed statistically significant symptom relief. The recurrence rate in group A was significantly lower than that in group B at 36 months after the surgery (2.94% vs. 32.84%, P < .001). A cox proportional hazard model showed that relapse was significantly associated with coexisting ovarian endometriosis (adjusted hazard ratio [aHR], 2.94; 95% confidence interval [CI], 1.33-7.02, P = .015). Patients who received surgery-LNG-IUS had a lower risk of recurrence than those with surgery-alone (aHR, 0.07; 95% CI, 0.016-0.31, P < .001).

CONCLUSIONS

Conservative surgery with intraoperative placement of LNG-IUS is effective and well-accepted for long-term therapy with a lower recurrence rate for adenomyosis. Coexistent ovarian endometriosis is a major factor for adenomyosis relapse.

Risk factor analysis for adverse prognosis of the fetal ventricular septal defect (VSD)

BACKGROUND

Ventricular septal defect (VSD) is the most common subtype of congenital heart disease. In the present study, we aimed to determine whether chromosome aberration was associated with the occurrence of VSD and evaluate the association of VSD size, location and chromosome aberration with adverse outcomes in the Chinese fetuses.

METHODS

Fetuses with VSD and comprehensive follow-up data were included and evaluated retrospectively. Medical records were used to collect epidemiological data and foetal outcomes. For VSD fetuses, conventional karyotype and microarray analysis were conducted. After adjusting confounding factors by using multivariable logistic regression analyses, the association between chromosome variations and VSD occurrence was explored. The association between defect size, location and chromosome aberrations and adverse foetal outcomes was also investigated.

RESULTS

Chromosome aberration was the risk factor for VSD occurrence, raising 6.5-fold chance of developing VSD. Chromosome aberration, peri-membranous site and large defect size of VSD were significant risk factors of adverse fetal outcome. Chromosome aberrations, including pathogenic copy number variations (CNVs) and variations of uncertain significance (VUS), were both risk factors, increasing the risk of the adverse fetal outcome by 55.9 times and 6.7 times, respectively. The peri-membranous site would increase 5.3-fold risk and defects larger than 5 mm would increase the 7.1-fold risk for poor fetal outcome.

CONCLUSIONS

The current investigation revealed that chromosomal abnormalities, large defects, and the peri-membranous site were all risk factors for poor fetal outcomes. Our study also indicated that chromosome aberration was one of risk factors for the VSD occurrence.

Targeted sequencing identifies a novel SH2D1A pathogenic variant in a Chinese family: Carrier screening and prenatal genetic testing

X-linked lymphoproliferative disease type 1 (XLP1) is a rare primary immunodeficiency characterized by a clinical triad consisting of severe EBV-induced hemophagocytic lymphohistiocytosis, B-cell lymphoma, and dysgammaglobulinemia. Mutations in SH2D1A gene have been revealed as the cause of XLP1. In this study, a pregnant woman with recurrence history of birthing immunodeficiency was screened for pathogenic variant because the proband sample was unavailable. We aimed to clarify the genetic diagnosis and provide prenatal testing for the family. Next-generation sequencing (NGS)-based multigene panel was used in carrier screening of the pregnant woman. Variants of immunodeficiency related genes were analyzed and prioritized. Candidate variant was verified by using Sanger sequencing. The possible influence of the identified variant was evaluated through RNA assay. Amniocentesis, karyotyping, and Sanger sequencing were performed for prenatal testing. We identified a novel de novo frameshift SH2D1A pathogenic variant (c.251_255delTTTCA) in the pregnant carrier. Peripheral blood RNA assay indicated that the mutant transcript could escape nonsense-mediated mRNA decay (NMD) and might encode a C-terminal truncated protein. Information of the variant led to success prenatal diagnosis of the fetus. In conclusion, our study clarified the genetic diagnosis and altered disease prevention for a pregnant carrier of XLP1.
