Proteinuria in predicting adverse outcomes in women with severe features of pre-eclampsia from a developing country: A prospective cohort study. Int J Gynaecol Obstet 2024; 165:1064-1071. [PMID: 38149697 DOI: 10.1002/ijgo.15308] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/13/2023] [Revised: 11/08/2023] [Accepted: 12/04/2023] [Indexed: 12/28/2023]
Abstract
OBJECTIVE To study the adverse maternal and perinatal outcomes in women with severe pre-eclampsia (SPE) among different ranges of proteinuria. METHODS This prospective cohort study was conducted in Jawaharlal Institute of Postgraduate Medical Education and Research, India. After obtaining informed written consent, the 202 singleton women fulfilling the criteria of severe features of pre-eclampsia were stratified based on the value of urine protein-creatinine ratio (UPCR) as mild, moderate, severe, and massive proteinuria during pregnancy. Clinical outcomes were assessed and patients were followed up until 12 weeks postpartum to identify persistent proteinuria and hypertension. RESULTS Of the 202 women with SPE, adverse maternal outcomes were seen in 34.65% (n = 70) and adverse perinatal outcomes in 75.74% (n = 153). The demographic and clinical factors were similar among women with increasing severity of proteinuria, except for mean systolic blood pressure, serum creatinine and total serum protein. UPCR was found to have a significant correlation with composite adverse perinatal outcome (P < 0.001) and individual outcomes of neonatal intensive care unit admission for >48 h (P = 0.01) and neonatal sepsis (P = 0.02) but not adverse maternal outcomes (P = 0.201). The optimum UPCR cutoff for adverse perinatal outcomes was 1.6 (sensitivity, 73.2%; specificity, 52.7%). In addition, 14.85% of the women had a persistently elevated UPCR and 3.96% had hypertension at 3 months postpartum. CONCLUSION In women with SPE, severe and massive proteinuria were related to composite adverse perinatal outcome but not composite adverse maternal outcome. Moreover, antenatal 24-h proteinuria was significantly associated with persistent proteinuria. Significant proteinuria in women with SPE poses a risk for chronic renal dysfunction, requiring follow-up.

Abstract
Objective The 24-h urine protein remains the gold standard to diagnose proteinuria in suspected preeclamptic patients. However, this test is time consuming and sometimes inaccurate. In this study, we aimed to analyse the correlation between the random urine protein/creatinine ratio (UPCR) and 24-h urine protein and to explore the clinical value of UPCR in the diagnosis of preeclampsia. Method We retrospectively evaluated 109 pregnant women from our hospital who had hypertensive diseases. They were grouped according to time of urine collection and disease severity to compare differences in random urine protein, urine creatinine, and UPCR. The correlation between the UPCR and 24-h urine protein was determined by Pearson's linear correlation. Results We found no statistically significant differences in random urine protein, urine creatinine, or UPCR among the four time of sampling groups. Further, random urine protein, UPCR, and 24-h urine protein between the gestational hypertension and preeclampsia groups differed significantly (P < 0.001). Correlation analysis showed significant positive correlation between random urine protein, and 24-h urine protein, and UPCR and 24-h urine protein, with r values of 0.789 and 0.810, respectively. According to the receiver operating characteristic (ROC) curve, the optimal threshold, sensitivity, specificity, and area under the curve of UPCR for the diagnosis of preeclampsia were 0.456 g/mmol, 67.8 %, 78.3 %, and 0.747, respectively (95 % confidence interval [CI], 0.65-0.844). Conclusion This study indicated that UPCR is significantly correlated with 24-h urine protein and is expected to replace the 24-h urine protein test as a diagnostic indicator of preeclampsia.

Abstract
OBJECTIVE To investigate the association between hypoproteinaemia with massive proteinuria and the incidence of small for gestational age in pre-eclampsia. DESIGN Retrospective cohort study using propensity score matching. SETTING Northwest Women's and Children's Hospital in Shaanxi Province, China, using data from January 2016 to December 2021. PARTICIPANTS Patients diagnosed with pre-eclampsia were grouped into the massive proteinuria group if the maximum proteinuria was >3.5 g/day and the minimum serum albumin was <30 g/L; otherwise, they were placed in the control group. OUTCOME MEASURES The primary outcome was the incidence of small for gestational age infants. Secondary outcomes included fetal death, admission to the neonatal intensive care unit, a 5 min APGAR score <7, severe small for gestational age, fetal growth restriction, birth weight, premature birth, and maternal outcomes such as eclampsia, encephalopathy, placental abruption, haemolysis, elevated liver enzymes and low platelet syndrome, heart failure and retinal detachment. RESULTS In total, 468 patients (234 from each group) were included, and the groups were well matched. The incidences of small for gestational age (33.76% vs 20.51%, OR 1.646, 95% CI 1.208 to 2.243, p=0.001), severe small for gestational age (14.70% vs 7.69%, OR 1.833, 95% CI 1.063 to 3.162, p=0.026), fetal growth restriction (23.93% vs 16.24%, OR 1.474, 95% CI 1.018 to 2.133, p=0.038), and the numbers of infants admitted to the neonatal intensive care unit (67.52% vs 58.55%, OR 1.153, 95% CI 1.003 to 1.326, p=0.044) were significantly higher in patients with hypoproteinaemia and massive proteinuria than in the control group. In addition, the median birth weight was significantly lower in the massive proteinuria group. There were no significant differences in maternal outcomes except for renal parameters, which were worse in the massive proteinuria group. CONCLUSION Hypoproteinaemia with massive proteinuria was associated with fetal growth and a higher incidence of small for gestational age infants in pre-eclampsia.

Abstract
Preeclampsia and other hypertensive disorders of pregnancy are major contributors to maternal morbidity and mortality worldwide. This group of disorders includes chronic hypertension, gestational hypertension, preeclampsia, preeclampsia superimposed on chronic hypertension, and eclampsia. The body undergoes important physiological changes during pregnancy to allow for normal placental and fetal development. Several mechanisms have been proposed that may lead to preeclampsia, including abnormal placentation and placental hypoxia, impaired angiogenesis, excessive pro-inflammatory response, immune system imbalance, abnormalities of cellular senescence, alterations in regulation and activity of angiotensin II, and oxidative stress, ultimately resulting in upregulation of multiple mediators of endothelial cell dysfunction leading to maternal disease. The clinical implications of preeclampsia are significant as there are important short-term and long-term health consequences for those affected. Preeclampsia leads to increased risk of preterm delivery and increased morbidity and mortality of both the developing fetus and mother. Preeclampsia also commonly leads to acute kidney injury, and women who experience preeclampsia or another hypertensive disorder of pregnancy are at increased lifetime risk of chronic kidney disease and cardiovascular disease. An understanding of normal pregnancy physiology and the pathophysiology of preeclampsia is essential to develop novel treatment approaches and manage patients with preeclampsia and hypertensive disorders of pregnancy. © 2023 American Physiological Society.

Abstract
Objective Preeclampsia, the main cause of maternal and perinatal deaths, is associated with several maternal complications and adverse perinatal outcomes. Some prediction models are uesd to evaluate adverse pregnancy outcomes. However, some of the current prediction models are mainly carried out in developed countries, and many problems are still exist. We, thus, developed and validated a nomogram to predict the risk of adverse pregnancy outcomes of preeclampsia in Chinese pregnant women. Methods The clinical data of 720 pregnant women with preeclampsia in seven medical institutions in Chongqing from January 1, 2010, to December 31, 2020, were analyzed retrospectively. The patients were divided into two groups: 180 cases (25%) with adverse outcomes and 540 cases (75%) without adverse outcomes. The indicators were identified via univariate analysis. Logistic regression analysis was used to establish the prediction model, which was displayed by a nomogram. The performance of the nomogram was evaluated in terms of the area under the receiver operating characteristic (ROC) curve, calibration, and clinical utility. Results Univariate analysis showed that 24 indicators were significantly different (P < 0.05). Logistic regression analysis showed that gestational age, 24 h urine protein qualitative, and TT were significantly different (P < 0.05). The area under the ROC curve was 0.781 (95% CI 0.737–0.825) in training set and 0.777 (95% CI 0.689–0.865) in test set. The calibration curve of the nomogram showed good agreement between prediction and observation. The analysis of the clinical decision curve showed that the nomogram is of practical significance. Conclusion Our study identified gestational age, 24 h urine protein qualitative, and TT as risk factors for adverse outcomes of preeclampsia in pregnant women, and constructed a nomogram that can easily predict and evaluate the risk of adverse pregnancy outcomes in women with preeclampsia.

Diagnosis of proteinuria using a random urine protein-creatinine ratio and its correlation with adverse outcomes in pregnancy with preeclampsia characterized by renal damage. J Clin Hypertens (Greenwich) 2022; 24:652-659.

Abstract
Based on a limited number of studies, a random urine protein‐creatinine ratio (uPCR) value of ≥ 0.3 indicates abnormal proteinuria in preeclampsia with renal damage. However, current guidelines do not recommend a reasonable diagnostic threshold of uPCR for severe preeclampsia with renal damage. Furthermore, the correlation between the uPCR value and clinical adverse outcomes remains poorly understood. The aim of the present study was to evaluate the value of uPCR in the diagnosis of significant proteinuria and to assess its correlation with adverse pregnancy outcomes in preeclampsia characterized by renal damage. In all, 1837 women were enrolled in this retrospective cohort study. Eventually, 961 women were enrolled under the exclusion criteria. First, the authors found that uPCR and 24‐hour proteinuria showed a significant association (r = 0.901). The optimal threshold of uPCR for diagnosing preeclampsia was 0.295, and for diagnosing severe preeclampsia the cut‐off was 0.625. Meanwhile, the adjusted odds ratio per 1 unit increase in ln (uPCR) was 1.679 (95% confidence interval [CI]:1.142–2.469) for severe adverse perinatal outcomes; 1.456 (95% CI: 1.242–1.705) for small for gestational age; 1.380 (95% CI: 1.051–1.811) for severe small for gestational age; 1.672 (95% CI: 1.210–2.310) for very early preterm birth; 1.989 (95% CI 1.726–2.293) for severe hypertension; and 2.279 (95% CI 1.906–2.724) for preterm birth. This study indicated that there was a significant and positive correlation between uPCR and 24‐hour urine protein. For neonatal and maternal adverse outcomes, uPCR is an independent predictor of prognosis.

Abstract
AIM To investigate the relationship between excessive gestational weight gain during the week prior to delivery (GWG) and severe morbidity and pregnancy termination among pregnant women with preeclampsia (hypertension with proteinuria). METHODS We compared GWG, laboratory data, and complication(s) between 94 preeclamptic women (preeclampsia group) with singleton pregnancies who delivered at ≥22 gestational weeks and 188 healthy women (control group) with singleton pregnancies undergoing elective cesarean deliveries. The gestational weeks at delivery were matched in the preeclampsia and control groups. RESULTS Among 282 total participants, median of GWG was significantly higher in the preeclampsia group than in the control group (1.6 kg vs. 0.5 kg, p < 0.0001). Furthermore, the GWG cutoff value for the preeclampsia group was 1.6 kg. The odds ratio for morbidity of preeclampsia among the women with GWG ≥1.6 kg at delivery was 12.5 (95% confidence interval, 6.31-24.5). In the preeclampsia group, 47 women with GWG ≥1.6 kg had significantly higher risks of hypoproteinemia, proteinuria, and renal dysfunction than those of 47 women with GWG < 1.6 kg. While, multivariate analysis showed 1.5 kg was a GWG cutoff value for predicting maternal morbidity (p < 0.0001); preeclamptic women with GWG ≥1.5 kg had a significantly higher risk of pulmonary edema than preeclamptic women with GWG < 1.5 kg (odds ratio, 7.77; 95% confidence interval, 1.64-36.7). CONCLUSION Excessive GWG in women with preeclampsia might be a predictor for severe maternal life-threatening complications requiring pregnancy termination.

Abstract
INTRODUCTION Since 2013, various guidelines for hypertension in pregnancy have been refined, no longer requiring proteinuria as a requisite criterion for preeclampsia. We aimed to evaluate the impact of the new definition on preterm birth (PTB) and adverse pregnancy outcomes. MATERIAL AND METHODS Women delivering in Ontario between April 2012 and November 2016 were included. Delivery <24+0/7 weeks, major fetal anomalies or preexisting renal disease were excluded. The primary outcome was livebirth <37, <34 or <32 weeks. Rates, adjusted rate ratios (aRR) and ratio of the rate ratio (RRR) were used to compare outcomes in the 2 years after the new Society of Obstetricians and Gynaecologists of Canada (SOGC) guideline (December 2014-November 2016; period 2) vs the 2 years before (April 2012-March 2014; period 1), among women with and without preeclampsia. RESULTS In all, 268 543 and 267 964 births in periods 1 & 2, respectively, were included. Respective preeclampsia rates increased significantly from 3.9% to 4.4% (p < 0.001), with no change in maternal morbidity rates. In preeclamptic women, respective rates of PTB <37 weeks were 21.0% and 20.7% (aRR 1.01, 95% confidence interval [CI] 1.00-1.02), with significant aRR for PTB <34 (0.86, 95% CI 0.77-0.96) and <32 weeks (0.79, 95% CI 0.67-0.94). A similar aRR was observed in women without preeclampsia. In preeclamptic women, composite severe neonatal morbidity decreased after guideline change (aRR 0.95, 95% CI 0.91-0.99), a finding not observed in women without preeclampsia (RRR 0.95, 95% CI 0.91-0.99). CONCLUSIONS The new definition of preeclampsia was associated with increased disease rates, a modest reduction in adverse neonatal outcomes and no change in maternal outcomes.

Abstract
INTRODUCTION The association between the degree of isolated gestational proteinuria and preeclampsia with severe features and other placental-mediated complications is controversial. The aim of this study was to evaluate whether a higher isolated proteinuria level is associated with an increased frequency of preeclampsia with severe features. MATERIAL AND METHODS This retrospective cohort study included pregnant women who were past 24 weeks of gestation and were diagnosed as having new-onset proteinuria ≥300 mg in a 24-h urine collection. Exclusion criteria included diagnosis of preeclampsia within 72 h from admission, chronic renal disease or chronic hypertension. The study population was divided into tertiles by proteinuria level and the association with preeclampsia with severe features was assessed in both bivariable and multivariable analysis. The main outcome measures was the development of preeclampsia with severe features. RESULTS Overall, 165 women were diagnosed with isolated gestational proteinuria, and 38 (23.0%) of them developed preeclampsia with severe features. Women in the increasing proteinuria tertile were more likely to develop preeclampsia with severe features (5.5%, 21.8%, 41.8%, respectively; p = 0.004). A multivariable logistic regression model controlling for background characteristics as well as gestational age at diagnosis, blood pressure, and kidney and liver function tests showed an increased risk of 14% to develop preeclampsia with severe features for every 500-mg rise in proteinuria level (adjusted odds ratio = 1.14, 95% confidence interval 1.03-1.27). CONCLUSIONS A higher isolated gestational proteinuria level was associated with an increased risk to develop preeclampsia with severe features among pregnant women past 24 weeks of gestation.

Earlier onset of proteinuria or hypertension is a predictor of progression from gestational hypertension or gestational proteinuria to preeclampsia. Sci Rep 2021; 11:12708.

Abstract
Although gestational hypertension (GH) is a well-known disorder, gestational proteinuria (GP) has been far less emphasized. According to international criteria, hypertensive disorders of pregnancy include GH but not GP. Previous studies have not revealed the predictors of progression from GP to preeclampsia or those of progression from GH to preeclampsia. We aimed to determine both sets of predictors. A retrospective cohort study was conducted with singleton pregnant women who delivered at 22 gestational weeks or later. Preeclampsia was divided into three types: new onset of hypertension/proteinuria at 20 gestational weeks or later and additional new onset of other symptoms at < 7 days or at ≥ 7 days later. Of 94 women with preeclampsia, 20 exhibited proteinuria before preeclampsia, 14 experienced hypertension before preeclampsia, and 60 exhibited simultaneous new onset of both hypertension and proteinuria before preeclampsia; the outcomes of all types were similar. Of 34 women with presumptive GP, 58.8% developed preeclampsia; this proportion was significantly higher than that of 89 women with presumptive GH who developed preeclampsia (15.7%). According to multivariate logistic regression models, earlier onset of hypertension/proteinuria (before or at 34.7/33.9 gestational weeks) was a predicator for progression from presumptive GH/GP to preeclampsia (odds ratios: 1.21/1.21, P value: 0.0044/0.0477, respectively).

Lei T, Qiu T, Liao W, Li K, Lai X, Huang H, Yuan R, Chen L. Proteinuria may be an indicator of adverse pregnancy outcomes in patients with preeclampsia: a retrospective study. Reprod Biol Endocrinol 2021; 19:71. [PMID: 33990220 PMCID: PMC8120921 DOI: 10.1186/s12958-021-00751-y] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/10/2021] [Accepted: 04/26/2021] [Indexed: 12/31/2022] Open
Abstract
BACKGROUND Proteinuria is one of the common manifestations of patients with preeclampsia (PE), but whether the severity of proteinuria is related to the pregnancy outcome of patients with preeclampsia remains controversial. The present study aimed to determine the relationship between 24-h proteinuria and adverse outcomes in patients with preeclampsia. METHODS The present retrospective study included 329 pregnant women in Chongqing, China. Patients were divided into PE group and non-PE group. PE group was stratified into three subgroups based on the level of 24-h proteinuria. Correlation analysis was used to analyze the correlation between biochemical indexes and adverse pregnancy outcome, and Logistic regression analysis was used to analyze the risk factors of adverse pregnancy outcome. The receiver operating characteristic curve (ROC) was used to evaluate the ability of 24-h urinary protein to distinguish the adverse pregnancy outcome in patients with preeclampsia. RESULTS (1) Between PE and non-PE group, cesarean section rate in PE group was significantly higher than that in non-PE group (84.4% vs. 25.9%, p < 0.001). Laboratory findings such as uric acid and creatinine level in PE group were higher than those in non-PE group. (2) Among mild (proteinuria < 0.3 g/24 h), moderate (0.3 g/24 h ≦ proteinuria < 2 g/24 h) and massive (proteinuria ≧ 2 g/24 h) groups, the frequencies of induced labor (p = 0.006) and stillbirth (p = 0.002) increased with the increase of 24-h proteinuria. (3) Adverse outcomes were positively correlated with 24-h proteinuria (adverse maternal outcomes: r = 0.239, p = 0.002; adverse fetal outcomes: r = 0.336, p < 0.001). (4) The best 24-h proteinuria cutoff values to determine stillbirth, premature and fetal distress were 3965.0 mg/24 h, 984.75 mg/24 h and 1503.85 mg/24 h and their odds ratio (95% confidence interval) were 12.46 (3.46-44.88), 2.48 (1.15-5.37) and 10.02 (2.14-46.80), respectively. CONCLUSIONS The severity of 24-h proteinuia may forecast adverse outcomes in women with preeclampsia. We suggest proteinuria should be retained as one of the monitoring indexes in patients with preeclampsia. TRIAL REGISTRATION Retrospectively registered. (LTMCMTS202001).
