[Nephrotic syndrome during pregnancy. Is it chronic glomerulonephritis or preeclampsia? Case report]

Nephrotic syndrome (NS) during pregnancy is a fairly rare pathology and its descriptions in the literature are few. For a long time, NS was associated only with an exacerbation of chronic glomerulonephritis or de novo nephritis, however, the experience of recent years has shown that NS can be a manifestation of the classical obstetric pathology - preeclampsia (PE). The appearance of massive proteinuria with the development of NS is most typical for early PE, which, of course, makes diagnosis difficult, especially if PE develops at an unusually early time (up to 20 weeks). To describe PE that does not fit into the classical criteria, the term "atypical" PE is now used, the development of which can be promoted by both obstetric and somatic risk factors. The presented clinical observation describes the development of early (within 14 weeks) severe PE with the NS at the onset of the disease in a patient with the first multiple pregnancy and complete hydatidiform mole (HM) of one of the fetuses. The progression of nephropathy with the addition of thrombotic microangiopathy and HELLP syndrome made it possible to assume the diagnosis of PE with a high probability. The rapid relief of all clinical manifestations after delivery confirmed this assumption. The role of HM as the main trigger of unusually early PE is discussed. Apparently, the patient's trophoblast disease in the form of hydatidiform mole caused the formation of a severe angiogenic imbalance already in the early stages of pregnancy, which led to the development of PE, which manifested NS as a consequence of podocytopathy due to VEGF deficiency. Thus, the development of NS in a pregnant patient without a history of kidney disease dictates, first of all, the exclusion of PE, until proven otherwise.

Atypical Preeclampsia before 20 Weeks of Gestation-A Systematic Review

This systematic review was conducted to gather evidence of preeclampsia occurring before the 20th week of gestation, additionally considering the role of PLGF and sFlt-1 in the development of the disease. In the three cases of preeclampsia before the 20th week of gestation presented in the authors' material, all pregnancies ended up with IUFD, and the SFlt-1/PLGF ratios were significantly elevated in all women. Eligible publications were identified with searches in the PubMed, Embase, Scopus, and Web of Science databases. No date or language restrictions were made. All original peer-reviewed scientific reports were included. A total of 30 publications were included in the final report, including case reports and case series. No other publication types regarding this issue were identified. In the literature, 34 cases of preeclampsia with onset occurring before the 20th week of gestation were identified, for a final total of 37 cases. Live births were reported in 5 cases (10.52%), and there were 9 intrauterine fetal demises (24.32%), and 23 terminations of pregnancy (62.16%). Preeclampsia before the 20th week of gestation is rare but can occur. We collected all available evidence regarding this phenomenon, with 37 cases reported worldwide. We call for large-scale cohort or register-based studies to establish revised definitions or develop new ones regarding the currently unrecognized very early onset preeclampsia.

Atypical preeclampsia without underlying disease and elevated sFlt-1/PlGF ratio

Atypical preeclampsia before 20 weeks of gestation without an underlying disease is very rare; however, the soluble Fms-like tyrosine kinase 1/placental growth factor (sFlt-1/PlGF) ratios remain unknown. Four pregnant women with no underlying disease, except for a history of childhood IgA vasculitis, developed preeclampsia at 13, 14, 17, and 18 weeks of gestation with sFlt-1/PlGF ratios of 1589, 1183, 500, and 1460 pg/mL, respectively. Their pregnancies were terminated, and they delivered within 2 weeks. All previously abnormal clinical findings normalized within 3 months. The sFlt-1/PlGF ratios were elevated in the four patients with atypical preeclampsia without underlying disease before 20 weeks of gestation. A high sFlt-1/PlGF ratio may be indicative of preeclampsia when no underlying disease is present in pregnancies of less than 20 weeks of gestation.

Recurrent spontaneous hepatic rupture in pregnancy: A case report

RATIONALE

Spontaneous and repeated hepatic ruptures caused by hemolysis, elevated liver enzymes, and low platelets (HELLP) syndrome are uncommon but life-threatening conditions that rarely occur early in the second trimester of pregnancy.

PATIENT CONCERNS

We describe a patient who experienced spontaneous hepatic ruptures in the absence of hypertension during the early second trimesters of both her first and second pregnancies.

DIAGNOSES

A 34-year-old multiparous woman without hypertension was admitted at 21 weeks' gestation because of a spontaneous hepatic rupture with hemoperitoneum. Four years previously, the patient had undergone an exploratory laparotomy during her first pregnancy that involved the ligation of bleeders, because a hepatic capsule rupture had caused hemoperitoneum development.

INTERVENTIONS

Unlike the first pregnancy, she was managed nonsurgically and conservatively during the second pregnancy, and she underwent frequent laboratory analyses and magnetic resonance imaging follow-up. On day 11 of the patient's hospital admission, we decided to deliver the baby at 23 weeks' gestation, because her condition had deteriorated.

OUTCOMES

Non-surgical management improved the patient's outcome, and the baby was born alive, even though the pregnancy was in the early second trimester and the maternal condition was deteriorating rapidly.

LESSONS

HELLP syndrome without hypertension and the recurrence of an intrahepatic rupture at an extremely premature gestational age are rare. This patient's findings suggested HELLP syndrome, which was subsequently diagnosed. This patient's clinical course highlights the difficult decisions made by clinicians for mothers and fetuses.
