It is associated with complications such as elevated serum lactate dehydrogenase (LDH) levels. LDH is an intracellular enzyme that increases in response to cellular death. Since preeclampsia leads to cellular death, serum LDH levels may reflect the severity of preeclampsia and serve as a guide in patient management. This study aims to estimate serum LDH levels in women with preeclampsia and those without, and compare the levels between the two groups.<br> <b>Methods:</b> A cross-sectional study was conducted in the Department of Biochemistry, in collaboration with the Department of Obstetrics and Gynecology at RIMS, Imphal, from February 2021 to September 2022. The study included 100 participants, 50 diagnosed with preeclampsia and 50 non-preeclamptic women attending RIMS hospital. Blood samples were collected from the patient, and serum LDH levels were estimated using a spectrophotometric method. All the data were analyzed using SPSS V21.0.<br> <b>Results:</b> The study revealed that serum LDH levels were significantly higher (P-value < 0.05) in women with preeclampsia (510.10 &plusmn; 184.26 IU) compared to pregnant women without preeclampsia (284.38 &plusmn; 97.35 IU). Serum LDH levels were positively correlated with an increase in blood pressure.<br> <b>Conclusion</b>: This study showed that serum LDH levels were higher in patients with preeclampsia compared to non-preeclamptic women, and LDH levels were positively correlated with higher blood pressure. Measuring serum LDH levels can help diagnose preeclampsia, allowing for better monitoring and timely management of affected women.</span></span></div> Pregnancy, Blood pressure, Hypertension 9 11 http://mlj.goums.ac.ir/browse.php?a_code=A-10-1438-1&slc_lang=en&sid=1 Yanglem Ajitkumar Singh 100319475328460031261 100319475328460031261 No Department of Obstetrics and Gynaecology, Regional Institute of Medical Sciences (RIMS), Imphal, Manipur, India Kshetrimayum Roshita Devi kshetriroshita@gmail.com 100319475328460031262 100319475328460031262 Yes Department of Biochemistry, Shija Academy of Health Sciences, Imphal, Manipur, India Sangeeta Naorem drsangeetan@gmail.com 100319475328460031263 100319475328460031263 No Department of Biochemistry, Regional Institute of Medical Sciences, Imphal, Manipur, India Victoria Kshetrimayum drvictoriaksh@gmail.com 100319475328460031264 100319475328460031264 No Department of Biochemistry, Regional Institute of Medical Sciences, Imphal, Manipur, India Sunie Laishram sunielaishram@gmail.com 100319475328460031265 100319475328460031265 No Department of Biochemistry, Regional Institute of Medical Sciences, Imphal, Manipur, India Niketa Ashem Officialniketa@gmail.com 100319475328460031266 100319475328460031266 No Department of Biochemistry, Regional Institute of Medical Sciences, Imphal, Manipur, India
