INTRODUCTIONRecent periodicals direct that reactive carbonyl compounds are formed due to existing oxidative stress in type 2 diabetes mellitus, which further nonenzymatically react with proteins and lipids to form irreversible advanced glycation end products (AGE) and advanced lipoxidation end products (ALE). In type 2 diabetes mellitus, insulin resistance plays a pivotal role in hyperglycaemia. In this study, we tried to fi nd the relation between insulin resistance and carbonyl stress.
MATERIALS AND METHODSForty-seven patients of type 2 diabetes mellitus (age 51 ± 5.06 years) were selected and fasting plasma glucose, serum insulin, total carbonyl compounds, HbA1c, thiobarbituric acid reacting substances (TBARS) and Trolox equivalent antioxidant capacity (TEAC) were estimated using standard protocols. Homeostatic model assessement of insulin resistance (HOMA-IR) was evaluated from fasting plasma glucose and serum insulin levels.
RESULTSWe found highly significant correlations of carbonyl compounds with HOMA-IR, fasting plasma glucose and glycated haemoglobin (HbA1c). Correlations of lipid peroxidation end product, TBARS were not so significant.
CONCLUSIONFindings from this study indicate that the level of carbonyl compounds can be a biomarker of insulin resistance in type 2 diabetes mellitus.

Objective: To determine the role of high-sensitive C-reactive protein (hsCRP) in predicting the severity of preeclampsia in a high-population, resource-poor country.Patients and Methods: This prospective cohort study was conducted at the Department of Obstetrics and Gynaecology of Calcutta National Medical College, India, from March 2021 to September 2022. A total of 180 participants were divided into three equal groups: patients with severe preeclampsia and non-severe preeclampsia and healthy pregnant women.Results: The levels of the biomarkers hsCRP and uric acid differed significantly between women with preeclampsia and healthy women, with cutoff levels of 3.72 mg/L and 5.15mg/dL, respectively, as determined using receiver operating characteristic (ROC) curve analysis. HsCRP was also able to differentiate severe preeclampsia from non-severe preeclampsia at a cutoff level ≥8.75 mg/L (high Youden index >0.6). However, uric acid levels failed to discriminate between pregnant women with severe and non-severe preeclampsia. Elevated hsCRP levels were strongly associated with low birth weight of newborns in pregnant women with preeclampsia and healthy control groups (P=0.001) and with disease severity (P<0.001), respectively.Conclusions: HsCRP can be used as an important diagnostic tool to exclude and evaluate the severity of preeclampsia.
