AI Article Synopsis
- The study aimed to explore the link between restless legs syndrome (RLS) and severe preeclampsia through a case-control design involving 147 women with severe preeclampsia and 147 with normal pregnancies.
- Participants completed a questionnaire regarding pregnancy symptoms, including those related to RLS, and underwent a severity assessment using a specific rating scale.
- Results showed a similar prevalence of RLS in both groups, with 13.61% diagnosed overall and no significant differences in RLS severity between women with severe preeclampsia and controls, suggesting the conditions are not significantly related.
Article Abstract
Objective: This study sought to determine whether there is an association between restless legs syndrome (RLS) and severe preeclampsia using a case-control study design.
Methods: A total of 147 patients with severe preeclampsia and 147 patients with normal pregnancies were evaluated for symptoms of RLS. In the first phase, before or immediately after delivery, participants were given a questionnaire on common complaints experienced during pregnancy. Mixed with these complaints were the symptoms that comprised the diagnostic criteria for RLS. If a participant indicated she met the diagnositic criteria, she was informed about RLS. In the second phase, a severity evaluation was performed in this population using the International Restless Legs Syndrome Study Group Rating Scale.
Results: Among the participants, independent of the presence of preeclampsia, 13.61% met the criteria for a diagnosis of RLS. There was no statistical difference between groups (severe preeclampsia: 12.93% vs. controls: 14.29%; odds ratio [OR] 0.89; 95% CI 0.46-1.74, P = 0.37). After analysis, 65% of patients with RLS had a score on the International Restless Legs Syndrome Study Group Rating Scale compatible with "very severe" or "severe" RLS. There was again no statistical difference between groups for the combination of "severe" and "very severe" scoring criteria (severe preeclampsia: 68.42% vs. controls: 61.90%; OR 1.33; 95% CI 0.36-4.93, P = 0.66) and "very severe" alone (severe preeclampsia: 21.05% vs. controls: 4.76%; OR 5.33; 95% CI 0.54-52.73, P = 0.11).
Conclusion: The prevalence of RLS among pregnant women in our study was in accordance with the medical literature and avoided the probable bias caused by the high number of other symptoms experienced during pregnancy. There were no significant differences between normotensive participants and those with severe preeclampsia. In general, symptom severity was high, with a tendency toward greater severity in patients with severe preeclampsia, but this difference did not reach statistical significance.

Wernicke's Encephalopathy (WE) is a rare but severe condition primarily caused by thiamine deficiency, often seen in pregnant women who experience severe vomiting, such as in hyperemesis gravidarum. This case report details a 38-year-old woman at 27 weeks of gestation who developed altered consciousness, cerebellar ataxia, and hyperlactatemia following persistent vomiting. Brain MRI demonstrated characteristic bilateral abnormalities consistent with WE.

Background: Preeclampsia (PE) is a serious condition characterized by hypertension and proteinuria after 20 weeks of gestation. The exact cause of PE is unknown but may involve abnormalities in the renin-angiotensin-aldosterone system (RAAS) and endothelial nitric oxide synthase (eNOS). Genetic variations in angiotensinogen (AGT), angiotensin-converting enzyme (ACE), and eNOS genes have been associated with PE.

Background: Preeclampsia is a hypertensive pregnancy disorder marked by endothelial damage. Healthy endothelium is covered by a protective glycocalyx layer, which, when degraded, releases detectable products into the blood. Sphingosine-1-phosphate (S1P) is a cardiovascular biomarker involved in glycocalyx preservation, linked to placentation and preeclampsia development.

Introduction: Urinary tract infections are prevalent among pregnant women and can lead to serious maternal and neonatal complications. Hypertensive disorders of pregnancy, a leading cause of maternal morbidity, may be associated with urinary tract infections. This study investigates whether bacteriuria detected via routine urinalysis, a standard screening in Indonesia, contributes to hypertension risk during pregnancy, aiming to enhance clinical management and screening protocols.
