Severe, very early onset preeclampsia in a Covid 19-positive woman with a twin pregnancy presenting with a hydatidiform mole and coexisting normal fetus: a case report.

ABSTRACT: Cases of hydatidiform moles with a coexisting fetus are sparse and patients are at high risk for severe complications. Patients and physicians often face the dilemma of the wish to continue pregnancy until viability of the fetus while the risk for maternal complications increases. We present an educational case of a twin pregnancy presenting with a hydatidiform mole and coexisting normal fetus with a placenta praevia. The patient developed severe, early onset preeclampsia with beginning HELLP-syndrome and was tested Covid-19 positive in the further course. Termination of pregnancy was conducted via caesarean section at 18 + 6 weeks of pregnancy. Histopathology and genetic analysis confirmed a complete hydatidiform mole next to a normal placenta. Close follow-up examinations were conducted and showed normal findings including ß HCG levels normalizing within 5 months. This case combines several rare, difficult and severe medical conditions and demonstrates how an individualized therapy by an interdisciplinary team covering a highly sensitive topic was developed in a situation where no guidelines exist.

Project description:BackgroundHydatidiform mole (HM), also called a molar pregnancy, is characterised by an overgrowth of foetal chorionic tissue within the uterus. HMs may be partial (PM) or complete (CM) depending on their gross appearance, histopathology and karyotype. PMs usually have a triploid karyotype, derived from maternal and paternal origins, whereas CMs are diploid and have paternal origins only. Most women with HM can be cured by evacuation of retained products of conception (ERPC) and their fertility preserved. However, in some women the growth persists and develops into gestational trophoblastic neoplasia (GTN), a malignant form of the disease that requires treatment with chemotherapy. CMs have a higher rate of malignant transformation than PMs. It may be possible to reduce the risk of GTN in women with HM by administering prophylactic chemotherapy (P-Chem). However, P-Chem given before or after evacuation of HM to prevent malignant sequelae remains controversial, as the risks and benefits of this practice are unclear.ObjectivesTo systematically review the evidence for the effectiveness and safety of P-Chem to prevent GTN in women with a molar pregnancy.Search methodsWe performed electronic searches in the Cochrane Gynaecological Cancer Specialised Register, the Cochrane Central Register of Controlled Trials (CENTRAL, Issue 2, 2012), MEDLINE (1946 to February week 4, 2012) and EMBASE (1980 to week 9, 2012). The search strategy was developed using free text and medical subject headings (MESH). We handsearched reference lists of relevant literature to identify additional studies.Selection criteriaWe included randomised controlled trials (RCTs) of P-Chem for HM.Data collection and analysisTwo review authors independently assessed studies for inclusion in the review and extracted data using a specifically designed data collection form. Meta-analyses were performed by pooling data from individual trials using RevMan 5.1 software.Main resultsWe included three RCTs with a combined total of 613 participants. One study compared prophylactic dactinomycin to no prophylaxis (60 participants); the other two studies compared prophylactic methotrexate to no prophylaxis (420 and 133 participants). All participants were diagnosed with CMs. We considered the latter two studies to be of poor methodological quality.P-Chem reduced the risk of GTN occurring in women following a CM (3 studies, 550 participants; RR 0.37; 95% confidence interval (CI) 0.24 to 0.57; I(2) = 0%; P < 0.00001), However, owing to the poor quality of two of the included studies, we performed sensitivity analyses excluding these two studies. This left only one small study of high-risk women to contribute data for this primary outcome (59 participants; RR 0.28; 95% CI 0.10 to 0.73; P = 0.01), therefore we consider this evidence to be of a low quality.The time to diagnosis was longer in the P-Chem group than the control group (2 studies, 33 participants; mean difference (MD) 28.72; 95% CI 13.19 to 44.24; P = 0.0003) and the P-Chem group required more courses to cure subsequent GTN (1 poor-quality study, 14 participants; MD 1.10; 95% CI 0.52 to 1.68; P = 0.0002). We consider this evidence to be of a low to very low quality for similar reasons to those listed above.There were insufficient data to perform meta-analyses for toxicity, overall survival, drug resistance and reproductive outcomes.Authors' conclusionsP-Chem may reduce the risk of progression to GTN in women with CMs who are at a high risk of malignant transformation; however, current evidence in favour of P-Chem is limited by the poor methodological quality and small size of the included studies. As P-Chem may increase drug resistance, delay treatment of GTN and expose women unnecessarily to toxic side effects, this practice cannot currently be recommended.
