P0263A NEPHROLOGIST'S LOOK AT HYPERTENSIVE DISORDERS OF PREGNANCY

Abstract Background and Aims Preeclampsia (PE) is a pregnancy-related syndrome of variable severity that falls under the broad category of hypertensive disorders of pregnancy (HDP). The relationship between PE and chronic kidney disease (CKD) is not entirely understood. Once considered a self-limited disease healed by delivery, it is now acknowledged that PE is a marker of cardiovascular and kidney health in the long term. The aim of this study was to review the data of women with hypertensive disorders of pregnancy at our institution, to identify need and to organize a conjoint nephrology and obstetrical activity in our setting Method We retrospectively reviewed all the medical charts of the patients hospitalized in the last two years for hypertensive disorders of pregnancy and who delivered in our Hospital. The cohort was divided into two groups: gestational hypertension (GH) and PE. A descriptive analysis of the clinical-laboratoristic was performed (t-test for continuous data with normal distribution). Results We identified 93 cases of hypertensive disorders of pregnancy on a total of 3279 deliveries (2.8%), 47 GH and 46 PE [2 cases of HELLP syndrome and 1 of eclampsia included in the PE group]. These two groups showed similar mean age: 33.5±6 vs 34.9±6 years (p value= 0.25); serum creatinine (sCr) and uric acid at admission were statistically different, and higher in the PE group (sCr 0.57±0.15 and 0.66±0.2 – p=0.01 and uric acid 4.5±1.38 and 5.6±1.47 – p=0.01). Comorbidities were frequent in the PE group: thyroid disfunction was found in 17% of cases (7 hypothyroidism and 1 hyperthyroidism, all under treatment), coagulation abnormalities were present in 15% of cases (4 MTHFR mutation, 1 protein S deficiency, 1 prothrombin-gene mutation, 1 patient was positive for LLAC); gestational diabetes was diagnosed in 13% of the cases. We identified 1 renal transplant recipient, 1 IgA-vasculitis patient, 1 patient with family medical history positive for PE (in her twin sister); none of these patients had been identified as at high risk for PE. At hospital admission, 54% of the patients were on antihypertensive treatment, 7 of them for chronic hypertension and 18 for gestational hypertension (12 of these patients underwent a previous hospitalization during the same pregnancy, diagnosed with gestational hypertension); at admission only 24% of PE patients were treated with anticoagulant or antiplatelet prophylaxis. Caesarean section was performed in 36 cases (78%). All but one children live-born, the exception being a child from a multiple pregnancy (quadruplets). Conclusion A multidisciplinary approach and a nephrological follow-up are increasingly indicated in PE. Our series underlines a high prevalence of comorbidity or risk factors, including thyroid disfunction, gestational diabetes and coagulation abnormalities. The high prevalence (7/46) of chronic hypertension and the fact that the two patients with kidney disease were not identified as at risk for PE underlines the potential role for developing a synergic approach between nephrologist and obstetricians.

Control Study

Introduction Basal plate myometrium (BPMYO), the pathological presence of myometrial fibers in the basal plate, is a common finding on pathological examination of the placenta, yet its clinical correlates are not well studied. As myometrial fibers are frequently located in proximity to poorly converted maternal spiral arteries, our objective was to determine whether BPMYO is associated with hypertensive disorders of pregnancy (HDP), a well-known clinical sequela of abnormal maternal artery remodeling. Methods This case–control study included women who delivered a live-born singleton gestation whose placentas were sent for pathological examination. Cases were women with HDP (gestational hypertension, preeclampsia, or HELLP syndrome) as defined by American College of Obstetricians and Gynecologists. Controls were women without HDP. Women with chronic hypertension were excluded. The primary outcome was the presence of BPMYO. Secondary outcomes included the pathologic stage of BPMYO and the incidence of pathologically defined accreta. Each outcome was compared between cases and controls in bivariable and multivariable analyses. Results Of the 306 women who met inclusion criteria, 230 (75%) had HDP. BPMYO was present in 99 (32%) of placentas. Compared to controls, cases were younger, had higher body mass index, and were more likely to have diabetes, be nulliparous, deliver preterm, and have had a prior cesarean. There were no differences in the incidence of BPMYO, stage of BPMYO, or incidence of pathologically defined accreta between cases and controls. These findings persisted after controlling for potential confounders. Conclusions Although BPMYO may be more common in the setting of abnormal placental vasculature, there is no significant association between BPMYO and HDP.

Background: Abnormal uric acid levels in patients with preeclampsia and eclampsia affect both maternal and fetal outcome negatively. This study was done to know the alterations in these serum levels in comparison to normal pregnancy and also among various hypertensive disorders of pregnancies.Methods: Maternal serum uric acid levels were compared among cases and controls in relation to disease severity, mode of delivery, maternal outcome.Results: In group A (cases), 10 patients had raised uric acid levels, of which 5 were severe preeclampsia, 3 were eclampsia and 2 cases of chronic hypertension superimposed preeclampsia. P value is 0.001 (highly significant). Also serum uric acid is significantly elevated in hypertensive disorders of pregnancy compared with controls with a P value of 0.001.Conclusions: Significant correlation was observed between maternal serum uric acid, disease severity and maternal outcome. Our study concludes that uric acid can be considered as a sensitive prognostic indicator of severity in hypertensive disorders of pregnancy.

Abstract Background Little is known about the long-term risk of renal disease following adverse pregnancy outcomes, such as hypertensive disorders of pregnancy (HDP), gestational diabetes (GDM) or preterm delivery. We aimed to investigate associations between adverse pregnancy outcomes and maternal chronic kidney disease (CKD) and end-stage kidney disease (ESKD), by synthesising results of relevant studies. Methods A systematic search of PubMed, EMBASE and Web of Science was done up to July 2018. Case-control and cohort studies were eligible for inclusion if they provided original effect estimates for associations between adverse pregnancy outcomes (HDP, GDM, preterm) and maternal renal disease (primary outcomes: CKD, ESKD; secondary outcomes: renal hospitalisation, renal mortality). Two independent reviewers extracted data and assessed risk of bias. Random effects meta-analyses were conducted to determine pooled adjusted odds ratio (AOR) and 95% confidence interval (95%CI) for each association. Results Of 5,120 studies retrieved, 21 studies met inclusion criteria (4,483,847 participants). HDP was associated with increased odds of ESKD (AOR 6.58, 95%CI 4.06-10.65), CKD (AOR 2.08, 95%CI 1.06-4.10), renal hospitalisation (AOR 2.29, 95%CI 1.42-3.71). The magnitude of association was dependent on HDP subtype: AOR for preeclampsia and ESKD was 4.87 (95%CI 3.01-7.87); gestational hypertension and ESKD was 3.65 (95%CI 2.34-5.67); other HDP (including chronic hypertension) and ESKD was 14.67 (95%CI 3.21-66.97). Preterm delivery was associated with increased odds of ESKD (AOR 2.16, 95%CI 1.64-2.85). GDM was associated with increased odds of CKD among black women (AOR 1.78, 95%CI 1.18-2.70), but not Caucasian women (AOR 0.81, 95%CI 0.58-1.13) Conclusions Women who experience adverse pregnancy outcomes have increased odds of renal disease, especially after HDP. Risk stratification and preventive interventions may be needed to reduce the risk of clinically significant renal disease in mothers. Key messages This is the first study to summarise the long-term risk of renal disease among women who experience a range of adverse pregnancy outcomes. Women who experience hypertensive disorders in pregnancy, preterm delivery, or gestational diabetes are at increased odds of renal disease.

AbstractBackgroundOne of the most common medical problems associated with pregnancy is hypertension. Hypertensive disorders of pregnancy (HDP), which has been attributable to abnormal placentation may have adverse effects on both mother and foetus if left unchecked. The objective of this study was to determine the prevalence of Hypertensive Disorders of Pregnancy (HDP), the morphological variations of human placenta in HDP, and maternal and perinatal outcomes in HDP.Materials and MethodsThis was a prospective case-control study, conducted at Komfo Anokye Teaching Hospital (KATH), Ghana. The progression of pregnancy in normotensive and hypertensive pregnant women, and the eventual perinatal outcomes were closely followed. Statistical analysis was performed using IMB-SPSS version 23. Associations were considered significant at p values of ≤ 0.05.ResultsFrom a total of 214 deliveries recorded during the period of study, 84 (39.25%) were hypertensives. Forty four (52%) of the hypertensives had preeclampsia, 28 (33.3%) had gestational hypertension, 6 (7.1%) had eclampsia, 4 (4.8%) had chronic hypertension, and 2 (2.4%) had preeclampsia superimposed on chronic hypertension. The frequency of placental haematoma, placental infarction, and placental calcification in the normotensives were significantly (p=0.001) lower than that of the hypertensives. The mean placental weight (p = 0.01), placental volume (p = 0.001), placental diameter (p = 0.03), and placental thickness (p = 0.001) of the normotensives were significantly higher than those of the hypertensives. The number of normotensives in whom labour was induced, who had their babies delivered by caesarean section, and who were admitted after they had given birth were significantly (p=0.001) lower than that of hypertensives who underwent similar procedures. No stillbirths were recorded in the normotensives compared with four in the hypertensives. The number of babies delivered to the normotensives who were admitted to the NICU was significantly (p=0.001) lower than those delivered by hypertensives.ConclusionThere was a high prevalence of hypertensive disorders of pregnancy in the study site. The condition adversely affected placental development and perinatal outcomes. These adverse effects can be curtailed by embarking on a vigorous health education drive.

Singleton Pregnancies

Objective Metformin has been found to have a role in promoting vascular remodeling and angiogenesis which may reduce the risk of developing preeclampsia. Prior studies have shown a decrease in the incidence of hypertensive disorders of pregnancy in patients with type 2 and gestational diabetes taking metformin. We hypothesize metformin exposure decreases the risk of developing hypertension in patients with type 2 diabetes. Study Design Retrospective cohort study from 2009 to 2019 of singleton pregnancies was complicated by type 2 diabetes. We compared patients who received metformin throughout pregnancy to those with no metformin exposure. The primary outcome was a hypertension composite defined as gestational hypertension, preeclampsia with or without severe features, HELLP syndrome, or eclampsia. Individual hypertensive outcomes and neonatal outcomes were secondarily evaluated. Logistic regression was used to adjust for confounding variables. Results A total of 254 pregnancies were included. Women exposed to metformin were significantly less likely to develop hypertension composite compared with nonexposed women (22.7 vs. 33.1%, aOR 0.53, 95% CI 0.29–0.96). The incidence of preeclampsia with severe features was also significantly lower in those who received metformin compared with those who did not (12.1 vs. 20.7%, aOR 0.38, 95% CI 0.18–0.81). There were no differences in preterm birth prior to 34 or 37 weeks, fetal growth restriction, or birth weight between the study groups. A subgroup analysis of women without chronic hypertension also had a significantly lower risk of developing preeclampsia with severe features (7.6 vs. 17.8%, aOR 0.35, 95% CI 0.13–0.94). Conclusion Metformin exposure was associated with a decreased risk of composite hypertensive disorders of pregnancy in patients with pregestational type 2 diabetes. These data suggest that there may be benefit to metformin administration beyond glycemic control in this patient population. Key Points

The Relationship

Background and Purpose: Hypertensive disorders of pregnancy (HDP) comprise 4 subtypes. Previous studies have not investigated the relationship between stroke risk, different HDP subtypes, and follow-up time, which was the purpose of this study. Methods: Data of 17 588 women aged 18 to 45 years who had a history of HDP in Taiwan from 2000 to 2017 was retrospectively reviewed. After matching with confounders, 13 617 HDP women and 54 468 non-HDP women were recruited. Results: HDP women had an adjusted hazard ratio (aHR) of 1.71 (95% CI, 1.46−2.00) for stroke, and 1.60 (1.35−1.89) and 2.98 (2.13−4.18) for ischemic and hemorrhagic stroke, respectively ( P <0.001 for all). The overall stroke risk in the HDP group was still 2.04 times 10 to 15 years after childbirth (1.47−2.83, P <0.001). Although the risks of both ischemic and hemorrhagic stroke persisted, their risk time trends were different. The risk of ischemic stroke reached peak during 1 to 3 years after childbirth with an aHR of 2.14 (1.36–3.38), while hemorrhagic stroke risk gradually increased and had an aHR of 4.64 (2.47−8.73) after 10 to 15 years of childbirth (both P <0.001). Among the 4 HDP subtypes, chronic hypertension with superimposed preeclampsia had the highest stroke risk (aHR=3.86, 1.91−7.82, P <0.001), followed by preeclampsia–eclampsia (aHR=2.00, 1.63−2.45, P <0.001), and gestational hypertension (aHR=1.68, 1.13−2.52, P <0.05); chronic preexisting hypertension had the lowest stroke risk (aHR=1.27, 0.97−1.68, P >0.05). Furthermore, multiple HDP combined with preeclampsia had aHR of 5.48 (1.14−26.42, P <0.05). Conclusions: The effect of HDP on the risk of future stroke persisted for up to 17 years, both for ischemic and hemorrhagic strokes. The presence of multiple HDP and preeclampsia further increase the stroke risk.

Objectives: To provide up-to-date data concerning hypertensive disorders of pregnancy on maternal and neonatal profiles in Indonesia. Methods: Retrospective clinical audit on all pregnancy-associated hypertensive women between 1 January 2020 and 31 March 2020 at Cianjur General District Hospital. Results: Preeclampsia accounts for 66.8% (235/352) of hypertensive disorders of pregnancy, gestational hypertension 29% (102/352) and chronic hypertension 4.3% (15/352). Compared to other pregnant women, those with preeclampsia, on average, had higher systolic and diastolic blood pressures and poorer kidney (ureum and creatinine) and liver function (aspartate transaminase enzyme and alanine transaminase enzyme) profiles (p < 0.001, < 0.001, < 0.001, 0.003, 0.033 and 0.002, respectively), and required more intensive care admission. Neonates from women with severe forms of preeclampsia (eclampsia and HELLP syndrome (haemolysis, elevated liver enzymes, low platelets)) had, on average, lower birthweight (p = 0.015 and 0.048, respectively) and birth length (p = 0.021, 0.017). Neonates from eclamptic mothers had poorer APGAR (appearance, pulse, grimace, activity and respiration) scores (p = 0.006 and 0.005, respectively). Conclusion: Hypertensive disorders of pregnancy exerts adverse maternal and neonatal outcomes, particularly among eclampsia and HELLP-syndrome neonates. Various challenges remain for optimal management.

Abstract Background Hypertensive disorders of pregnancy are associated with chronic kidney disease. Early detection of renal dysfunction enables implementation of strategies to prevent progression. International guidelines recommend review at 6–8 weeks postpartum to identify persistent hypertension and abnormal renal function, but evidence for the efficacy of this review is limited. Methods All women attending a specialist fetal-maternal medicine clinic for hypertensive disorders of pregnancy (pre-eclampsia, chronic hypertension, gestational hypertension) were invited for a 6–8 weeks postpartum review of their blood pressure and renal function in order to establish the prevalence and independent predictors of renal dysfunction. Renal dysfunction was defined as low estimated Glomerular Filtration Rate (eGFR < 60 ml/min/1.73 m2) or proteinuria (24-h protein excretion > 150 mg or urinary albumin-to-creatinine ratio > 3 mg/mmol). All women attending a specialist clinic for hypertensive disorders were invited for a 6–8 weeks postpartum review of their blood pressure and renal function. Demographics, pregnancy and renal outcomes were prospectively collected. Results Between 2013 and 2019, 740 of 1050 (70.4%) women who had a pregnancy complicated by a hypertensive disorder attended their 6–8 weeks postpartum visit. Renal dysfunction was present in 32% of the total cohort and in 46% and 22% of women with and without pre-eclampsia, respectively. Multivariate logistic regression demonstrated that independent predictors were pre-eclampsia, chronic hypertension, highest measured antenatal serum creatinine, highest measured antenatal 24-h urinary protein, and blood pressure ≥ 140/90 mmHg at the postnatal visit. Conclusions Renal dysfunction was present in one in three women with hypertensive disorders of pregnancy at 6–8 weeks postpartum. This includes women with gestational hypertension and chronic hypertension without superimposed pre-eclampsia, and thus these women should also be offered postnatal review. Graphic abstract

Background Preeclampsia and gestational hypertension are hypertensive disorders of pregnancy (HDP) that identify an increased risk of developing chronic hypertension and cardiovascular disease later in life. Postpartum follow‐up may facilitate early screening and treatment of cardiovascular risk factors. Our objective is to describe patterns of postpartum visits with primary care and women's health providers (eg, family medicine and obstetrics) among women with and without HDP in a nationally representative sample of commercially insured women. Methods and Results We conducted a retrospective cohort study using insurance claims from a US health insurance database to describe patterns in office visits in the 6 months after delivery. We identified 566 059 women with completed pregnancies between 2005 and 2014. At 6 months, 13% of women with normotensive pregnancies, 18% with HDP, and 23% with chronic hypertension had primary care visits ( P <0.0001 for comparing HDP and chronic hypertension groups with control participants). Only 58% of women with HDP had 6‐month follow‐up with any continuity provider compared with 47% of women without hypertension ( P <0.0001). In multivariable analysis, women with severe preeclampsia were 16% more likely to have postpartum continuity follow‐up (adjusted odds ratio, 1.16; 95% CI, 1.2–1.21). Factors associated with a lower likelihood of any follow‐up included age ≥30 years, Black race, Hispanic ethnicity, and having multiple gestations. Conclusions Rates of continuity care follow‐up after a pregnancy complicated by hypertension were low. This represents a substantial missed opportunity to provide cardiovascular risk screening and management to women at increased risk of future cardiovascular disease.

Background: Hypertensive disorders complicate 5-10% of all pregnancies and together forms the deadly triad- along with hemorrhage and heart disease that contributes greatly to maternal morbidity and mortality. Objective of this study was to determine the prevalence of hypertensive disorders of pregnancy and its maternal complications in patients attending obstetrics and gynaecology department, Government Mohan Kumaramangalam Medical College Hospital, Salem.Methods: This is a prospective study conducted from August 2018 to July 2019 in the department of obstetrics and gynaecology. Patients diagnosed with hypertensive disorders of pregnancy was evaluated and data were collected.Results: A total of 19,383 pregnant women visited obstetrics and gynaecology department over a period of one year, out of which 2028 were diagnosed with hypertensive disorders of pregnancy. Hence the prevalence of hypertensive disorders in pregnancy is 10.4%. Among 2028 hypertensive disorder cases, Gestational hypertension were 962 cases (47.4%), pre-eclampsia 661 cases (32.6%), chronic hypertension 166 cases (8.2%) and pre-eclampsia superimposed on chronic hypertension 239 cases (11.8%). The prevalence was highest among primigravida (54%) compared to multigravida (46%). Hypertensive disorders were highest among the age group of 18-22 years in our study. Most common maternal complication in our study was HELLP syndrome.Conclusions: Prevalence of hypertensive disorders was high in our study. Early detection and timely intervention decrease the maternal complications.
