PMID: 2152069

A review of eclampsia in Kelantan was undertaken from 1983-1988. There were 146 documented cases in the state (66 per 100,000 deliveries). Eight maternal deaths occurred. Sixty seven (45.9%) were primigravida. Six of the 79 multiparous women developed eclampsia for the first time following remarriages to new partners. The multisystem dysfunction resulting from eclampsia resulted in varied maternal complications. Fatal cerebral haemorrhage (3 cases), acute pulmonary oedema (8 cases), acute renal failure (6 cases), HELLP Syndrome (8 cases) and acute abruptio placentae were the commoner complications. The average number of convulsions per patient was 1.3. The mean gestation of mothers who delivered prematurely (28.2%) was 34.6 weeks and that for those at term (71.8%) was 39.1 weeks. The caesarean section rate was 42.5%. The perinatal mortality rate was 185.9 per 1000. The implications of this high maternal and fetal mortality and morbidity are discussed in the light of the health delivery system and patient education. A team approach to medical management of eclampsia with the need for intensive care monitoring is suggested.

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.

This study was undertaken to determine the presence of thyroid autoantibodies and associated pregnancy complications from 49 pregnant women with thyroid disease. There were 31 (63%) women with Graves' disease (GD) and 18 (37%) with primary hypothyroidism (PHT). A total of 26 (53.1%) women, 19 (61%) with GD and seven (39%) with PHT, had positive antibodies. Six had thyroid peroxidase antibodies (TPO), one with thyroglobulin antibody (TG) and eight had TSH receptor antibodies (TR). Two had a mixture of antibodies involving TG/TPO (one GD vs one PHT), four with TG/TPO/TR (all had GD) and five with TPO/TR (four with GD vs one with PHT). There were associations in women with positive thyroid antibodies and pre-eclampsia (15.4%), abruptio placenta (4%), caesarean deliveries (31%), postpartum thyroiditis (19.2%) and abnormal neonatal thyroid function (15.4%). Women with positive thyroid antibodies in pregnancy need close care during and after pregnancy, as they can develop complications affecting both mother and fetus.

Systemic lupus erythematosus pregnancies: the Sarawak experience and review of lupus pregnancies in Asia

Teh CL, Wong JS, Ngeh NK, Loh WL

Rheumatol Int, 2011 Sep;31(9):1153-7.

We performed a cross-sessional study of all systemic lupus erythematosus (SLE) pregnancies during a 4-year period (2006-2009) to describe the clinical features, maternal and foetal outcomes in our centre. There were 48 pregnancies in 44 women with SLE. Our patients have a mean age of 30.0 years (SD 6.36) and a mean disease duration of 40.67 months (SD 48.23). Our patients have complicated pregnancies: 32.7% have SLE flares, 17.3% have preeclampsia and 48.9% needed caesarean sections. There were 20.0% foetal losses and 17.8% preterm deliveries in our patients. SLE flares contributed to 60.0% of foetal losses in our patients. Lupus pregnancies in our centre generally have a good maternal and foetal outcome comparable to developed countries in Asia. The low incidence of APS, the high usage of hydroxychloroquine and the high SLE remission rate in our patients prior to conceptions contributed to the good outcome.

An episode of clinically recovered acute kidney injury (r-AKI) has been identified as a risk factor for future hypertension and cardiovascular disease. Our objective was to assess whether r-AKI was associated with future preeclampsia and other adverse pregnancy outcomes and to identify whether severity of AKI or time interval between AKI and pregnancy was associated with pregnancy complications. We conducted a retrospective cohort study of women who delivered infants between 1998 and 2016 at Massachusetts General Hospital. AKI was defined using the 2012 Kidney Disease Improving Global Outcomes laboratory criteria with subsequent clinical recovery (estimate glomerular filtration rate, >90 mL/min per 1.73 m2 before conception). AKI was further classified by severity (Kidney Disease Improving Global Outcomes stages 1-3) and time interval between AKI episode and the start of pregnancy. Women with r-AKI had an increased rate of preeclampsia compared with women without previous r-AKI (22% versus 9%; P<0.001). Infants of women with r-AKI were born earlier (gestational age, 38.2±3.0 versus 39.0±2.2 weeks; P<0.001) and were more likely to be small for gestational age (9% versus 5%; P=0.002). Increasing severity of r-AKI was associated with increased risk of preeclampsia for stages 2 and 3 AKI (adjusted odds ratio, 3.5; 95% confidence interval, 2.1-5.7 and adjusted odds ratio, 6.5; 95% confidence interval, 3.5-12.0, respectively), but not for stage 1 (adjusted odds ratio, 1.7; 95% confidence interval, 0.9-3.2). A history of AKI before pregnancy, despite apparent full recovery, was associated with increased risk of pregnancy complications. Severity and timing of the AKI episode modified the risk.

BACKGROUND: The American Heart Association's formal characterization of cardiovascular health combines several metrics in a health-oriented, rather than disease-oriented, framework. Although cardiovascular health assessment during pregnancy has been recommended, its significance for pregnancy outcomes is unknown.
OBJECTIVE: The purpose of this study was to examine the association of gestational cardiovascular health-formally characterized by a combination of 5 metrics-with adverse maternal and newborn outcomes.
STUDY DESIGN: We analyzed data from the Hyperglycemia and Adverse Pregnancy Outcome study, including 2304 mother-newborn dyads from 6 countries. Maternal cardiovascular health was defined by the combination of the following 5 metrics measured at a mean of 28 (24-32) weeks' gestation: body mass index, blood pressure, lipids, glucose, and smoking. Levels of each metric were categorized using pregnancy guidelines, and the total cardiovascular health was scored (0-10 points, where 10 was the most favorable). Cord blood was collected at delivery, newborn anthropometrics were measured within 72 hours, and medical records were abstracted for obstetrical outcomes. Modified Poisson and multinomial logistic regression were used to test the associations of gestational cardiovascular health with pregnancy outcomes, adjusted for center and maternal and newborn characteristics.
RESULTS: The average age of women at study exam was 29.6 years old, and they delivered at a mean gestational age of 39.8 weeks. The mean total gestational cardiovascular health score was 8.6 (of 10); 36.3% had all ideal metrics and 7.5% had 2+ poor metrics. In fully adjusted models, each 1 point higher (more favorable) cardiovascular health score was associated with lower risks for preeclampsia (relative risk, 0.67 [95% confidence interval, 0.61-0.73]), unplanned primary cesarean delivery (0.88 [0.82-0.95]), newborn birthweight >90th percentile (0.81 [0.75-0.87]), sum of skinfolds >90th percentile (0.84 [0.77-0.92]), and insulin sensitivity <10th percentile (0.83 [0.77-0.90]). Cardiovascular health categories demonstrated graded associations with outcomes; for example, relative risks (95% confidence intervals) for preeclampsia were 3.13 (1.39-7.06), 5.34 (2.44-11.70), and 9.30 (3.95-21.86) for women with ≥1 intermediate, 1 poor, or ≥2 poor (vs all ideal) metrics, respectively.
CONCLUSION: More favorable cardiovascular health at 24 to 32 weeks' gestation was associated with lower risks for several adverse pregnancy outcomes in a multinational cohort.

Fulltext The combinatorial diversity of KIR and HLA class I allotypes in Peninsular Malaysia

Killer cell immunoglobulin-like receptors (KIRs) interact with polymorphic human leucocyte antigen (HLA) class I molecules, modulating natural killer (NK) cell functions and affecting both the susceptibility and outcome of immune-mediated diseases. The KIR locus is highly diverse in gene content, copy number and allelic polymorphism within individuals and across geographical populations. To analyse currently under-represented Asian and Pacific populations, we investigated the combinatorial diversity of KIR and HLA class I in 92 unrelated Malay and 75 Malaysian Chinese individuals from the Malay Peninsula. We identified substantial allelic and structural diversity of the KIR locus in both populations and characterized novel variations at each analysis level. The Malay population is more diverse than Malay Chinese, likely representing a unique history including admixture with immigrating populations spanning several thousand years. Characterizing the Malay population are KIR haplotypes with large structural variants present in 10% individuals, and KIR and HLA alleles previously identified in Austronesian populations. Despite the differences in ancestries, the proportion of HLA allotypes that serve as KIR ligands is similar in each population. The exception is a significantly reduced frequency of interactions of KIR2DL1 with C2+ HLA-C in the Malaysian Chinese group, caused by the low frequency of C2+ HLA. One likely implication is a greater protection from preeclampsia, a pregnancy disorder associated with KIR2DL1, which shows higher incidence in the Malay than in the Malaysian Chinese. This first complete, high-resolution, characterization of combinatorial diversity of KIR and HLA in Malaysians will form a valuable reference for future clinical and population studies.
