Background: HELLP syndrome may increase adverse pregnancy outcomes, though the incidence of it is not high. At present, the impact of HELLP syndrome on P-AKI (acute kidney injury during pregnancy) and maternal and infant outcomes is controversial. Thus, we conducted a meta-analysis to find out more about the relationship between HELLP syndrome and P-AKI and pregnancy outcomes.
Methods: We systematically searched PubMed, Embassy and Cochrane Databases for cohort studies and RCT to assess the effect of HELLP syndrome on P-AKI and maternal and infant outcomes. Study-specific risk estimates were combined by using fixed-effect or random-effect models.
Results: This meta-analysis included 11 cohort studies with a total of 6333 Participants, including 355 cases of pregnant women with HELLP syndrome and 5979 cases that without. HELLP syndrome was associated with relatively higher risk of P-AKI (OR4.87 95% CI 3.31 ~ 7.17, P<0.001), fetal mortality (OR1.56 95% CI 1.45 ~ 2.11, P<0.001) and Maternal death (OR3.70 95% CI 1.72 ~ 7.99, P<0.001).
Conclusions: HELLP syndrome is associated with relatively higher risk of P-AKI, fetal mortality and maternal death.

Background: sFLT-1 has been implicated in the pathogenesis of HDP. We aimed to examine the role of maternal and fetal polymorphisms in risk of HDP and severe-spectrum disease.
Methods: Cases of HDP (143) and controls (169) from mother-baby dyads were recruited at the Los Angeles County Women's and Children's Hospital (WCH).
Rare association of posterior reversible encephalopathy syndrome (PRES) with hemolysis, elevated liver enzymes and low platelets (HELLP) syndrome - A case report and review of the literature.

Introduction: The hemolysis-elevated liver enzymes-low platelet counts (HELLP) syndrome and posterior reversible encephalopathy syndrome (PRES) are rare conditions that can complicate pregnancy and the early postpartum period. Although both are closely related to hypertensive pregnancy disorders, their association is rarely described, so the outcome of these patients remains unknown. We present a case report of PRES associated with HELLP syndrome and a review of all previously published cases, including demographic characteristics, clinical presentation, treatment, and outcome.

Objectives: Eclampsia remains a principal cause of maternal mortality, especially in low- and middle-income countries. The frequent association with Posterior Reversible Encephalopathy Syndrome (PRES) underscores the critical role of neuroimaging in clinical assessment. We aimed to evaluate tomographic findings in women with eclampsia and analyze clinical factors associated with these abnormalities.

Unlabelled: Haemolysis, elevated liver enzymes and low platelets (HELLP) syndrome is a poorly understood, life-threatening multisystemic condition related to pregnancy with a rapid onset, typically observed in patients with severe pre-eclampsia. Various mechanisms may lead to diffuse endothelial damage associated with HELLP and possible brain involvement. A comprehensive review of PubMed, Embase and Cochrane databases was conducted to examine the clinical, laboratory and radiological features associated with postpartum HELLP syndrome, particularly its potential association with posterior reversible encephalopathy syndrome (PRES).

Hematologic complications are common in pregnancy and can significantly impact both maternal and fetal health. Recognizing and treating these complications can be challenging due to the limited evidence available to guide clinical consultants. Iron deficiency anemia is the most prevalent hematologic issue in pregnancy and often occurs due to increased maternal blood volume and the nutritional demands of the growing fetus.
