Soluble fms-like tyrosine kinase-1 (sFlt-1) and placental growth factor (PlGF) contribute in the development of preeclampsia and are suggested as prediction markers in healthy pregnant women but limited data is available in women with major preeclampsia risk factors. This study aimed to determine the role of sFlt-1 and PlGF in predicting preeclampsia among high risk pregnant women. This was a prospective study and samples were collected for a period of ten months. Blood samples were obtained from 84 pregnant women who had at least one risk factor for preeclampsia at 25 to 28 weeks and at 29 to 36 weeks of gestation. SFlt-1 and PlGF concentrations were determined by immunoassay method. There were significantly higher median sFlt-1 and sFlt-1:PlGF ratio at gestational interval 25 to 28 weeks and sFlt-1:PlGF ratio at 29 to 36 weeks in high risk women who developed preeclampsia. Significant lower median serum PlGF levels at 25 to 28 weeks and 29 to 36 weeks were observed in this group of women. In conclusion, the concentrations of these markers were altered in high risk preeclamptic women, a similar pattern seen in low risk preeclamptic women. However the predictive value of these markers could not be established clearly.

Preeclampsia patients have frequently been found to experience hyperuricaemia and this may result in poor outcomes compared to those with normal uric acid levels. This study aimed to determine the relationship of hyperuricaemia in pre-eclampsia patients with foetal and maternal outcomes. This prospective cohort study involved 79 patients in a tertiary centre from year 2016 to 2018. Blood samples were taken antenatally and at the 6th week, post-delivery for renal function including serum uric acid level. Our findings indicate that there was a higher incidence of poor maternal and foetal outcomes in the hyperuricaemia group than the normal uric acid group. Serum uric acid has been shown to be a significant predictor for low birth weight and premature delivery in preeclampsia patients. It was also found that there was a significant negative correlation between uric acid level and antenatal creatinine clearance (rs = -0.338, p = .002). The assessment of the serum uric acid level seems to be important to ensure better outcomes in patients with preeclampsia.Impact statementWhat is already known on this subject? Preeclampsia is a serious pregnancy-related complication and remains as one of the most important cause of maternal and foetal morbidity and mortality, affecting 2-8% in all pregnancy. Many studies have established the association between hyperuricaemia and preeclampsia. Besides, numerous studies have found that hyperuricaemia contributed to adverse maternal and foetal outcomes.What the results of this study add? There was a significant increase in adverse foetal and maternal outcomes in the hyperuricaemia group compared to the normal uric acid group. This study revealed that serum uric acid remains a significant predictor for low birth weight and premature delivery in preeclampsia patients.What the implications are of these findings for clinical practice and/or further research? Hyperuricaemia does not merely become an indicator for the severity of disease in preeclampsia patients but also indicates adverse foetal outcomes. Large population-based studies are required to establish the absolute maternal and foetal outcomes in patients with hyperuricaemia. Besides, further studies are recommended on long-term implication of hyperuricaemia which is not limited to only during antenatal period.

In this review, we discuss the potential use of antimalarial drugs as an adjuvant therapy for preeclampsia, focusing on the mechanisms of action of this class of drugs in the context of preeclampsia. In particular, hydroxychloroquine has been shown to have various beneficial effects on patients with systemic lupus erythematosus. There are several pathways targeted by the antimalarial drugs that are similar to the pathophysiology of preeclampsia and hence offering opportunities to develop novel therapies to treat the disease. Given the safety profile of hydroxychloroquine in pregnancy, there is merit in exploring the efficacy of this drug as an adjuvant therapy in women with early onset preeclampsia.

Leptin has important roles in numerous physiological functions, including those in the regulation of energy balance, and in immune and reproductive systems. However, in the recent years, evidence has implicated it in a number of obesity-related diseases, where its concentrations in serum are significantly elevated. Elevated serum leptin concentrations and increased placental leptin secretion have been reported in women with hypertensive disorders of pregnancy. Whether leptin is responsible for this disorder remains to be established. Leptin injections in healthy rats and mice during pregnancy result in endothelial activation, increased blood pressure and proteinuria. A potential role for leptin in the pathogenesis of pre-eclampsia is hypothesised, particularly in women who are overweight or obese where serum leptin concentrations are often elevated. This review summarises pertinent information in the literature on the role of leptin in puberty, pregnancy, and hypertensive disorders of pregnancy. In particular, the possible mechanism that may be involved in leptin-induced increase in blood pressure and proteinuria during pregnancy and the potential role of marinobufagenin in this disease entity. We hypothesise a significant role for oxidative stress in this, and propose a conceptual framework on the events that lead to endothelial activation, raised blood pressure and proteinuria following leptin administration.

PMID: 8781637

Determinations of total calcium, total magnesium, calcium ion, parathyroid hormone and 6-keto-prostaglandin-F1 alpha levels were carried out on 84 blood samples from 4 groups of women categorised as non-pregnant normotensive (NNP), pregnant normotensive (NP), pregnancy-induced hypertension (PIH) and pre-eclampsia (PE). PIH was clinically diagnosed when the diastolic pressure was more than 90 mmHg and was only hypertensive during pregnancy while PE was with additional proteinuria after 20 weeks of gestation. Compared to NNP women, total calcium and parathyroid hormone levels were of lower levels (p < 0.05) in NP women while in PIH women, total calcium and 6-keto-prostaglandin-F1 alpha levels were also lowered (p < 0.05). Compared to NNP women, PE women's levels of total calcium, calcium ion and 6-keto-prostaglandin-F1 alpha decreased (p < 0.05) while parathyroid hormone level increased (p < 0.05). When compared to the NP women, PE women had decreased levels (p < 0.05) of total calcium as well as calcium ion and increased level (p < 0.05) of parathyroid hormone. Calcium ion was found to be negatively correlated (NNP : r = -0.883, p = 0.008/NP : r = -0.931, p = 0.000) while parathyroid hormone was positively correlated (NNP : r = 0.904, p = 0.013/NP : r = 0.913, p = 0.000) with mean arterial pressure.

Calcium supplementation to decrease the incidence of hypertensive disorders of pregnancy: a review

Manju K

Family Physician, 1994;6:6-8.

Hypertensive disorders of pregnancy is a major cause of fetal and maternal morbidity. Epidemiologic observations have shown an inverse association between calcium intake and incidence of eclampsia. Calcium supplementation has been reported to decrease blood pressure in pregnant women, although this remains controversial. The mechanism responsible for the effect of calcium on hypertinsion in pregnant women is unknown. This paper is a review of some of the recent calcium supplementation trials that have been carried out and their effectiveness in reducing systolic and diastolic blood pressure and decreasing the incidence of hypertensive disorders of pregnancy.

A confidential system of enquiry into maternal mortality was introduced in Malaysia in 1991. The methods used and the findings obtained up to 1994 are reported below and an outline is given of the resulting recommendations and actions.
PIP: This is a report on the methods, findings, resulting recommendations and actions of a study on maternal mortality in Malaysia during the period 1991-94. Maternal death was defined as the death of a woman while pregnant or within 42 days following termination of pregnancy from any cause related to the pregnancy or its management but not from accidental causes. Between 1991 and 1994 there were 1066 reported maternal deaths, and the maternal mortality ratios for the successive years were respectively 44, 48, 46 and 39 per 100,000 live births. The primary causes of maternal death were postpartum hemorrhage (24%), hypertensive disorders of pregnancy (16%), obstetric pulmonary embolism (13%), and associated medical conditions (7%). Analysis of the 375 deaths from 1992 - 1993 showed that the maternal mortality ratio was 53/100,000 live births for deliveries performed at home, 36/100,000 in government hospitals, and 21/100,000 in private institutions. Shortcomings among health personnel were detected in several cases; these involved failure to diagnose, failure to appreciate the severity of a patient's condition, inadequate therapy, and inappropriate, delayed or failed adherence to protocols. The high proportion of maternal mortality associated with substandard care demonstrates that it is important to make the standard of care more widely available. Reports have been circulated to institutions and organizations providing maternal care and to medical schools. Articles and case histories have been published, and many new protocols and procedures have been developed. Furthermore, seminars have been organized and training modules have been distributed to all involved in the provision of maternity care.

High-Sensitivity Cardiac Troponin I Levels in Normal and Hypertensive Pregnancy

Ravichandran J, Woon SY, Quek YS, Lim YC, Noor EM, Suresh K, et al.

Am J Med, 2019 03;132(3):362-366.

PMID: 30503877 DOI: 10.1016/j.amjmed.2018.11.017

PURPOSE: The purpose of this study was to examine the association of circulating concentrations of high-sensitivity cardiac troponin I (hs-cTn) in the various trimesters of pregnancy in patients with and without hypertension.

METHODS: This was a prospective cross-sectional study of pregnant and postnatal women aged between 18-35 years with no coexisting diseases. Serum samples were analysed for hs-TnI.

RESULTS: A total of 880 women (mean age = 29.1 years [standard deviation = 5.1 years]) were recruited with 129 (14%), 207 (24%), and 416 (47%) patients in the first, second, and third trimesters, respectively. Ninety (10%) participants were recruited in the postnatal period. During pregnancy 28 (3%) patients were classified as having pregnancy-induced hypertension and 10 (1%) as preeclampsia. High-sensitivity cardiac troponin I was measurable in 546 (62%) participants with a median of 1 ng/L (range 0 to 783 ng/L). Troponin concentrations were above the 99th percentile in 19 (2%) individuals. Patients with pregnancy-induced hypertension and preeclampsia had higher concentrations of hs-TnI (median 11 ng/L [interquartile range (IQR) 6 to 22 ng/L] vs 12ng/L [IQR 3 to 98 ng/L] vs 1 ng/L [IQR 0 to 1 ng/L]). In logistic regression modeling hs-cTnI concentration remained an independent predictor of pregnancy-induced hypertension or preeclampsia in both unadjusted and adjusted models (odds ratio 9.3 [95% confidence interval 5.8 to 16.3] and 11.5 [95% confidence interval 6.3 to 24.1], respectively, per doubling of hs-TnI concentrations).

CONCLUSIONS: Cardiac troponin measured using a high-sensitivity assay is quantifiable in the majority of young pregnant women with 2% of individuals having concentration above the 99th percentile sex-specific threshold. Patients with pregnancy-induced hypertension or preeclampsia had higher cardiac troponin concentrations. Cardiac troponin was a strong independent predictor of pregnancy-induced hypertension or preeclampsia in pregnant and postnatal women.
