Preeclampsia: Reflections on How to Counsel About Preventing Recurrence

What a paediatric nephrologist should know about preeclampsia and why it matters

Preeclampsia is a protean syndrome causing a kidney disease characterised by hypertension and proteinuria, usually considered transitory and reversible after delivery. Its prevalence ranges from 3-5 to 10% if all the related disorders are considered. This narrative review, on behalf of the Kidney and Pregnancy Study Group of the Italian Society of Nephrology, focuses on three reasons why preeclampsia should concern paediatric nephrologists and how they can play an important role in its prevention, as well as in the prevention of future kidney and cardiovascular diseases. Firstly, all diseases of the kidney and urinary tract diagnosed in paediatric age are associated with a higher risk of adverse pregnancy-related outcomes, including preeclampsia. Secondly, babies with low birth weights (small for gestational age, born preterm, or both) have an increased risk of developing the full panoply of metabolic diseases (obesity, hypertension, early-onset cardiopathy and chronic kidney disease) and girls are at higher risk of developing preeclampsia when pregnant. The risk may be particularly high in cases of maternal preeclampsia, highlighting a familial aggregation of this condition. Thirdly, pregnant teenagers have a higher risk of developing preeclampsia and the hypertensive disorders of pregnancy, and should be followed up as high risk pregnancies. In summary, preeclampsia has come to be seen as a window on the future health of both mother and baby. Identification of subjects at risk, early counselling and careful follow-up can contribute to reducing the high morbidity linked with this disorder.

Risk factors of preeclampsia among pregnant women admitted at labor ward of public hospitals, low income country of Ethiopia; case control study

BACKGROUND

Preeclampsia is a pregnancy-specific, multisystem disorder of unknown etiology, which characterized by new onset of high blood pressure & proteinuria after 20 weeks of gestation. Globally, it contributes 76,000 maternal deaths, 500,000 infant deaths annually, and the second common cause of maternal deaths. In Ethiopia, 19% of maternal deaths result from hypertensive disorder of Pregnancy.

OBJECTIVE

To assess the risk factors of preeclampsia among pregnant women admitted in labor ward of Public hospitals, Amhara Region Ethiopia, METHODS: A facility based unmatched case-control study design was conducted in two public hospitals of North Wollo Zone. Cases were pregnant women, who had confirmed diagnosis of preeclampsia, controls were those who had no evidence of preeclampsia, and 65 cases and 195 controls were selected by convenience and systematic random sampling techniques respectively. The collected data was interred in to in EPI INFO version 7.1, transferred, and analyzed using SPSS version 20.00 statistical software. Multivariate logistic regression was used to identify independent variables. Factors with P-value < 0.05 were taken as statistically significant of pre-eclampsia among pregnant women.

RESULT

All of the respondents of cases and controls were participated in the study. Factors associated with preeclampsia were respondents who had read and write (AOR = 3.22, 95% CI: (1.05-9.84)) and attended primary school [AOR = 7.02, 95% CI: (1.57-31.45)]. Those pregnant women, who had at least two ANC visit [AOR = 8.69, 95%CI: (1.43-52.85)] and those who had three visit [AOR = 12.59, 95%CI: (3.06-56.05)]. In addition to these, birth Interval less than 24 month [AOR = 4.09, 95% CI: (1.33-12.61)]. Birth Interval 24-35 month [AOR = 2.53, 95% CI: (1.38-11.87], respondents with family history of HPN (AOR = 5.93, 95%CI: (2.39-14.67), family history of DM [AOR = 2.15, 95%CI: (1.12-6.98)], and respondents with previous history of preeclampsia (AOR = 4.14 95%CI: (1.66-10.33) were identified significant factors of preeclampsia among pregnant women attended in labour ward.

CONCLUSION AND RECOMMENDATION

Educational status, antenatal care, lower birth interval, having family history of chronic HPN and DM, and history of preeclampsia were identified as major risk factors for occurrence of preeclampsia. Early detection of cases and intensive screening of pregnant women in every visit should be done and large-scale study will be done to identify other risk factors of preeclampsia.

A best practice position statement on the role of the nephrologist in the prevention and follow-up of preeclampsia: the Italian study group on kidney and pregnancy

Preeclampsia (PE) is a protean syndrome causing a transitory kidney disease, characterised by hypertension and proteinuria, ultimately reversible after delivery. Its prevalence is variously estimated, from 3 to 5% to 10% if all the related disorders, including also pregnancy-induced hypertension (PIH) and HELLP syndrome (haemolysis, increase in liver enzyme, low platelets) are included. Both nephrologists and obstetricians are involved in the management of the disease, according to different protocols, and the clinical management, as well as the role for each specialty, differs worldwide. The increased awareness of the role of chronic kidney disease in pregnancy, complicating up to 3% of pregnancies, and the knowledge that PE is associated with an increased risk for development of CKD later in life have recently increased the interest and redesigned the role of the nephrologists in this context. However, while the heterogeneous definitions of PE, its recent reclassification, an emerging role for biochemical biomarkers, the growing body of epidemiological data and the new potential therapeutic interventions lead to counsel long-term follow-up, the lack of resources for chronic patients and the increasing costs of care limit the potential for preventive actions, and suggest tailoring specific interventional strategies. The aim of the present position statement of the Kidney and Pregnancy Study Group of the Italian Society of Nephrology is to review the literature and to try to identify theoretical and pragmatic bases for an agreed management of PE in the nephrological setting, with particular attention to the prevention of the syndrome (recurrent PE, presence of baseline CKD) and to the organization of the postpartum follow-up.

Remote Monitoring of Hypertension Diseases in Pregnancy: A Pilot Study

Background

Although remote monitoring (RM) has proven its added value in various health care domains, little is known about the remote follow-up of pregnant women diagnosed with a gestational hypertensive disorders (GHD).

Objective

The aim of this study was to evaluate the added value of a remote follow-up program for pregnant women diagnosed with GHD.

Methods

A 1-year retrospective study was performed in the outpatient clinic of a 2nd level prenatal center where pregnant women with GHD received RM or conventional care (CC). Primary study endpoints include number of prenatal visits and admissions to the prenatal observation ward. Secondary outcomes include gestational outcome, mode of delivery, neonatal outcome, and admission to neonatal intensive care (NIC). Differences in continuous and categorical variables in maternal demographics and characteristics were tested using Unpaired Student’s two sampled t test or Mann-Whitney U test and the chi-square test. Both a univariate and multivariate analysis were performed for analyzing prenatal follow-up and gestational outcomes. All statistical analyses were done at nominal level, Cronbach alpha=.05.

Results

Of the 166 patients diagnosed with GHD, 53 received RM and 113 CC. After excluding 5 patients in the RM group and 15 in the CC group because of the missing data, 48 patients in RM group and 98 in CC group were taken into final analysis. The RM group had more women diagnosed with gestational hypertension, but less with preeclampsia when compared with CC (81.25% vs 42.86% and 14.58% vs 43.87%). Compared with CC, univariate analysis in RM showed less induction, more spontaneous labors, and less maternal and neonatal hospitalizations (48.98% vs 25.00%; 31.63% vs 60.42%; 74.49% vs 56.25%; and 27.55% vs 10.42%). This was also true in multivariate analysis, except for hospitalizations.

Conclusions

An RM follow-up of women with GHD is a promising tool in the prenatal care. It opens the perspectives to reverse the current evolution of antenatal interventions leading to more interventions and as such to ever increasing medicalized antenatal care.
