Clinical management of a quadruplet pregnancy combining a triplet pregnancy with a classical hydatidiform mole: case report and review of literature.

A 28-year-old Taiwanese woman who had received ovulation induction by clomiphene citrate (CC), follicular-stimulating hormone (FSH), and human chorionic gonadotrophin (hCG) treatment was diagnosed with a quadruplet pregnancy containing a hydatidiform mole and three fetuses at nine weeks' gestation. Expectant management failed to achieve any viable neonate due to massive antepartum haemorrhage and preterm delivery at 25 weeks' gestation. Five other cases previously reported involving quadruplets or triplets with a complete hydatidiform mole and two or three fetuses are reviewed. All cases ended as premature non-viable fetuses. Analysis of the clinical features, management, and outcome both in our patient and these reports suggest that more efficacious treatment planning, such as selective feticide, should be considered in order to improve the likelihood of attaining an advanced gestational age for a single fetus.

Two identical triplet sisters carrying a germline BRCA1 gene mutation acquire very similar breast cancer somatic mutations at multiple other sites throughout the genome.

Monozygotic twins, each of whom has breast cancer, offer a natural study population for gene-environmental interactions as causation of cancer, because they are genetically identical. If heritable factors play a large role in the origin of a neoplasm, disease concordance should be significant in monozygotic twins. Two monozygotic triplet sisters carrying a germline BRCA1 gene mutation (5382insC) who both developed breast cancer at early ages were studied for loss of heterozygosity (LOH) in their microdissected, paraffin-embedded tumors along with control blood and stromal breast tissue at 19 chromosomal arms using 161 microsatellite markers. Microdissected areas of normal lobular and ductal epithelium and ductal in situ carcinoma were also studied for LOH using a subset of microsatellite markers. The mother's DNA (extracted from peripheral blood lymphocytes) was analyzed to determine the parental allele under LOH in each case. Both tumors demonstrated similar histologic features suggestive of a secretory variant of ductal carcinoma. The tumors from both sisters had similar overall LOH frequency expressed by the fractional allelic loss (FAL) indices (0.56 vs. 0.60) and demonstrated concordance for loss or retention at 82 of 97 informative markers (85% correlation). In addition, detailed mapping analysis of several chromosomal arms revealed that identical breakpoints were detected in both tumors at several chromosome regions. Finally, in both sisters' tumors, when a chromosome exhibited allelic loss, all of the markers exhibited LOH of the same parental allele even when there were intervening regions of retention of heterozygosity. In contrast, 17 archival sporadic breast carcinomas demonstrated a wide range of FAL indexes and highly individual patterns of LOH. Our findings support the hypothesis that inherited factors play a role in the development of the multiple somatic deletions occurring in breast carcinomas. Whether one of these factors is the mutant BRCA1 allele or some other gene(s) remains to be determined. Genes Chromosomes Cancer 28:359-369, 2000.

Hydrops fetalis associated with homozygosity for hemoglobin Taybe (alpha 38/39 THR deletion) in newborn triplets.

Hemoglobin Taybe is an unstable alpha-chain hemoglobin variant caused by a deletion of a threonine residue at codon 38 or 39 of the alpha-1 globin chain. We describe preterm infant triplets born with hydrops fetalis and anemia who were found by DNA analysis to be homozygous for hemoglobin Taybe. All three infants developed intrauterine hemolytic anemia, which subsequently led to hydrops fetalis. To the best of our knowledge, this is the first description of hydrops fetalis associated with this hemoglobinopathy. We suggest that hemoglobin Taybe be considered in the differential diagnosis of hydrops fetalis and that known affected fetuses be carefully followed both antenatally and postnatally.

Congenital Pelger-Huet anomaly in triplets.

Congenital Pelger-Huet anomaly is an autosomal dominant disorder characterized by incomplete nuclear segmentation of granulocytes. The morphology of these mature but hyposegmented granulocytes may be confused with that of immature granulocytes (bands), thereby suggesting bacterial infection. We report the first known case of triplets with this condition, and emphasize the need to identify accurately this normal variant.

Hypoparathyroidism-retardation-dysmorphism (HRD) syndrome in triplets.

We report female triplets with the clinical and biochemical manifestations of hypoparatyroidism-retardation-dysmorphism (HRD) syndrome also known as Sanjad-Sakati syndrome. They were born at 35 weeks gestation after assisted pregnancy (in vitro fertilization). The parents are first degree cousins from Saudi Arabia.

Triplets with systemic lupus erythematosus.

We present herein the first case report of identical triplets who developed systemic lupus erythematosus (SLE). The children were diagnosed as having SLE in reverse birth order at ages 8, 9, and 11 years. Although genetically identical, each sibling manifested different clinical signs and symptoms; however, all 3 children did manifest skin rash, fatigue, and biopsy-proven glomerulonephritis at different ages. Findings of laboratory studies were similar, including positivity for antinuclear antibodies, anti-native DNA, and anti-double-stranded DNA, as well as low levels of complement. These findings confirmed SLE in each sibling.

Omphalocele-exstrophy-imperforate anus-spinal defects (OEIS) in triplet pregnancy after IVF and CVS.

BACKGROUND: Omphalocele-exstrophy-imperforate anus-spinal defects (OEIS) complex is a rare sporadic condition. CASE: We identified an infant with major malformations resembling OEIS. He was the product of a 30-week triplet pregnancy conceived by in vitro fertilization (IVF) and evaluated by chorionic villi sampling (CVS). In this article, we review the possible pathogenetic mechanisms in this case, including IVF, multiple gestation, trauma to the uterus or uterine vessels following CVS, and placenta accreta. CONCLUSIONS: We conclude that the cumulative effects of all or some of these factors may have resulted in uteroplacental insufficiency adequate to produce this phenotype. This case provides additional evidence for the uterine vascular pathogenesis of OEIS complex in humans.

Chorionic villus sampling and selective termination of a chromosomally abnormal fetus in a triplet pregnancy.

Transabdominal chorionic villus sampling (CVS) was performed on a patient with a triplet pregnancy. The karyotypes were as follows: 46,XX; 46,XY; and 46,XY/47,XXY. Selective termination was done on the affected fetus successfully by intrathoracic potassium chloride (KCl) injection. Amniocentesis which was performed at the same time confirmed the CVS results, showing the same mosaic findings. Following the procedure, the pregnancy proceeded uneventfully and two normal newborns were delivered at term.

Unusual segregation for 11q;22q parental translocation in a triplet pregnancy: prenatal diagnosis in chorionic villi and amniotic fluid.

The prenatal diagnosis of an 11q;22q translocation in a triplet pregnancy detected at the time of chorionic villus sampling (CVS) because of advanced maternal age is reported. Karyotypes obtained from two apparently different CV samples showed the balanced form of translocation, while the one obtained from a third empty sac showed the unbalanced form: 46,XX,-22,+der(22)t(11;22). Second-trimester amniocentesis confirmed the balanced translocation in one of the two viable fetuses and a normal karyotype in the other. The detected karyotypes derived from two different types of meiotic segregation, alternate and adjacent 1. To our knowledge, this is the first reported case of an unbalanced karyotype not due to a 3:1 meiotic segregation of this specific translocation.

Acardiac fetus in a triplet pregnancy.

The acardiac monster represents one of the most severe but rare congenital anomalies. It occurs only in multiple gestations associated with vascular anastomoses between the affected fetus and its co-twin. The prenatal diagnosis of an acardiac fetus must be suspected in any multiple gestation in which cardiac activity cannot be documented sonographically in a growing fetus. We report an acardiac fetus occurring in a spontaneously conceived triplet pregnancy. A review of the literature, including pathogenetic theories and sonographic reports, is discussed.

Conservative treatment of endometrial cancer permitting subsequent triplet pregnancy.

We report on a 28-year-old woman who received conservative treatment of endometrial carcinoma by curettage and progestins. After regression of endometrial lesions the patient's infertility was treated by gamete intrafallopian transfer (GIFT). Intact triplet pregnancy was diagnosed 3 weeks later. The patient was delivered of three infants by caesarean section following premature rupture of membranes at 30 weeks of gestation. Subsequent standard treatment of endometrial cancer by abdominal hysterectomy and bilateral salpingo-oophorectomy after 4 weeks revealed no clinical or histological evidence of persistent carcinoma. One year after surgery the patient remained without evidence of disease. We believe that individualized cancer therapy may be safely performed in carefully selected cases.

Fetal abnormality (Goldenhar syndrome) occurring in one of triplet infants derived from in vitro fertilization with possible monozygotic twinning.

Of 36 infants delivered following conception by in vitro fertilization (IVF), 1 case of significant fetal abnormality has been detected. The infant is one of male triplets exposed to medroxyprogesterone acetate (MPA) in utero and demonstrates abnormalities of the ear, vertebral column, and ribs which fit clearly into the oculoauriculovertebral syndrome described by Goldenhar and which have been reported in monozygotic twins with discordance. Marker studies including eight blood groups, HLA haplotype assignments, and banding studies of the chromosomes indicate that the infant and one of his brothers may well be identical (P less than 0.001 for dizygosity) except for the Fy(a) antigen. It is deduced that the fetal abnormality is not causally related either to MPA exposure or to the techniques applied during fertilization and early embryo culture, and furthermore, if the infant is the monozygotic twin of one of his brothers, the two phenomena are unrelated, as each was likely to have occurred at different stages of embryonic development.

Mother-daughter in vitro fertilization triplet surrogate pregnancy.

A successful triplet pregnancy has been established in a surrogate gestational mother following the transfer of five embryos fertilized in vitro. The oocytes were donated by her biological daughter, and the sperm obtained from the daughter's husband. The daughter's infertility followed a total abdominal hysterectomy performed for a postpartum hemorrhage as a result of a placenta accreta. Synchronization of both their menstrual cycles was obtained using oral contraceptive suppression for 2 months, followed by stimulation of both the surrogate gestational mother and her daughter such that embryo transfer would occur at least 48 hr after the surrogate gestational mother's own ovulation. This case raises a number of medical, social, psychological, and ethical issues.

A case of body stalk anomaly arising in the second baby of a triplet pregnancy after in-vitro fertilization and embryo transfer.

We report a case of body stalk anomaly arising in the second baby of a triplet pregnancy after in-vitro fertilization and embryo transfer (IVF-ET). Body stalk anomaly or limb-body wall complex is a rare congenital anomaly with a series of similar clinical manifestations and poor prognosis. IVF-ET is an effective treatment for various types of infertility. We summarize and discuss herein the relation with the sequence of genesis for such malformations and multiple pregnancies after IVF-ET.

Mitochondrial DNA control region diversity in hairs and body fluids of monozygotic triplets.

Length heteroplasmy of the homopolymeric cytosine stretch in the hypervariable region II of the mitochondrial D-loop was investigated in blood, buccal cells and hair shafts of monozygotic triplets. The proportions of length heteroplasmy were determined by cloning and sequencing of multiple independent clones. Blood and buccal cells showed an accumulation of molecules with one and two insertions of cytosine residues in relation to the Cambridge Reference Sequence (CRS). The results did not show statistically significant differences between blood and buccal cells of one and the same individual and also not between the three monozygotic brothers. In the hair samples a loss of cytosine residues was established in all three monozygotic individuals compared to blood and buccal cells, suggesting that this must be a regular process. Furthermore, the hair shaft samples showed significant differences between the frequencies of 7, 8 or 9 Cs in the poly C region comparing the three individuals (p<0.008) and in addition there were highly significant differences (p<0.0001) when comparing the results for six different hairs of each individual separately. From these results it can be assumed that besides a common genetic bottleneck during embryonic development, a post-embryonic bottleneck seems to exist in each hair follicle.

Monozygous triplets discordant for transient neonatal diabetes mellitus and for imprinting of the TNDM differentially methylated region.

Transient neonatal diabetes mellitus (TNDM) is associated with paternal over-expression of an imprinted locus on chromosome 6q24, which contains one differentially methylated region (DMR); maternal demethylation at the DMR accounts for approximately 20% of cases. Here we report female monozygous triplets, two of whom have TNDM arising from loss of maternal methylation within the TNDM DMR.
