A retrospective cohort in Istanbul’s Basaksehir Cam and Sakura City Hospital (2020–2023) included 73 women with preeclampsia and 30 healthy pregnant controls. FAR was higher versus controls but did not differ by severity, while UAR and LAR differed across groups. ROC analyses identified UAR and LAR cut-offs with reported sensitivity and specificity. UAR and LAR are proposed as better, accessible biomarkers for severe-feature-related delivery risk.","Article  \nFibrinogen to Albumin Ratio, Lactate Dehydrogenase to  \nAlbumin Ratio and Uric Acid to Albumin Ratio in Preeclampsia  \nEsra Selvi 1, *, Kübra Kurt Bilirer 1, Aybekcan Batman 1, ˙Izel Günay 2, Verda Alpay 1 and Hakan Erenel 1  \nAcademic Editor: Everett F.

We aimed to distinguish these two entities with the aid of fibrinogen to albumin ratio (FAR), uric to acid albumin ratio (UAR) and LDH to albumin ratio (LAR) . Methods: This retrospective study was conducted in Istanbul Basaksehir Cam and Sakura City Hospital between 2020 and 2023 . Seventy-three patients with preeclampsia were included in this study which were categorized into two groups according to disease severity: 40 patients with preeclampsia without severe features and 33 patients with severe features. Additionally, 30 healthy pregnant women were included as a control group. Neutrophil–lymphocyte ratio (NLR), monocyte–lymphocyte ratio (MLR), platelet–lymphocyte ratio (PLR), mean platelet volume (MPV), red cell distribution width (RDW), mean platelet volume (MPV), Uric acid, LDH, AST, ALT, fibrinogen, albumin, FAR, UAR and LAR were compared among the groups. Results: FAR was significantly higher in preeclampsia patients with and without severe features compared to control group (Odds ratio 8.32 for ≥0.139 vs. \u003C0.139, p \u003C 0.001) . There was no significant difference in FAR levels between preeclampsia patients according to disease severity. UAR and LAR were significantly different between preeclampsia patients with and without severe features and the control group (p \u003C 0.001) . Receiver operating characteristics (ROC) curves for UAR showed that a cut-off value of 1.727 had a sensitivity of 73% and a specificity of 68% in discriminating between preeclampsia with and without severe features (Odds ratio 5.53 for ≥1.727 vs. \u003C1.727) . ROC curves for LAR showed that a cut-off value of 79.09 had a sensitivity of 85% and a specificity of 73% in discriminating between preeclampsia with and without severe features (Odds ratio 14.76 for ≥79.09 vs. \u003C79.09) . Conclusions: UAR and LAR appear tobe better markers than FAR for identifying preeclamptic patients who require delivery due to severe features. They are easily accessible and promising biomarkers, and to our knowledge, this is the first study to evaluate LAR in this context. Further studies are needed to validate their diagnostic accuracy and compare their performance with established biomarkers.  \nKeywords: albumin; fibrinogen; LDH; preeclampsia; uric acid  \n1.
