<b><i>Objectives:</i></b> The objective of this study was to determine the relationship between the levels of stress biomarkers in cord blood and pre-eclampsia (PE) in a hospital-based population of pregnant patients and evaluate the effects on pregnancy outcomes. <b><i>Design:</i></b> This was an observational, case-control study. <b><i>Participants/Materials, Setting, Methods:</i></b> This case-control study included 282 patients with severe PE and 534 women with normal pregnancy. The umbilical cord was collected at delivery and tested for malonaldehyde (MDA), reactive oxygen species (ROS), superoxide dismutase, and homocysteine (Hcy) analysis. We performed a univariate general linear regression model analysis to control potential confounders and determined the underlying influencing factors for high MDA and ROS. A receiver operating characteristic curve analysis was conducted to determine the cutoff values for identifying severe PE. Further, the severe PE group was divided into the low- or high-MDA and low- or high-ROS subgroups according to the cutoff values. Finally, we created logistic regression models to estimate the adjusted odds ratio for each perinatal outcome in the high-MDA and high-ROS subgroup. <b><i>Results:</i></b> The levels of MDA and ROS levels were higher in women with severe PE than in normotensive pregnant patients. However, when adjusted for cord blood Hcy levels, the difference was insignificant. Additionally, both MDA (<i>r</i> = 0.359, <i>p</i> &#x3c; 0.001) and ROS (<i>r</i> = 0.473, <i>p</i> &#x3c; 0.001) were positively correlated with the cord blood Hcy level. The areas under the curve of MDA and ROS levels were 0.65 (95% confidence interval [CI]: 0.60–0.69) and 0.88 (95% CI: 0.86–0.90), respectively. Higher MDA and ROS levels were associated with increased risks of a low Apgar score, admission to the NICU, and assisted ventilation for the newborn. <b><i>Limitations:</i></b> The study design led to the exclusion of several participants. <b><i>Conclusions:</i></b> Increased levels of oxidative stress markers in the cord blood might be significantly associated with negative effects on newborns. High levels of Hcy in the cord blood might be associated with elevated MDA and ROS concentrations in women with severe PE.

Abstract Background To determine the relationship between the levels of stress biomarkers in cord blood and preeclampsia in a hospital-based population of pregnant patients, and to evaluate the resulting effects on pregnancy outcomes. Measures: This prospective case-control study included a total of 282 severe preeclamptic and 534 normal pregnant women. Fetal blood was collected from the umbilical cord at delivery and was utilized for Malonaldehyde (MDA), reactive oxygen species (ROS, superoxide dismutase (SOD) and homocysteine (Hcy) analysis. For a better assessment, we performed a univariate general linear regression model to control for potential confounders and determined the underlying influencing factors for high MDA and ROS. Moreover, a receiver operating characteristic curve analysis was conducted to determine the cutoff values for identifying severe preeclampsia. Further, the severe PE group was divided into the low or high MDA and low or high ROS subgroups according to their cut-off values. Finally, we created logistic regression models to estimate the adjusted odds ratio for each perinatal outcome in high-MDA and -ROS subgroup. Results MDA and ROS levels are higher in women with severe preeclampsia than in normotensive pregnant patients. However, when adjusted for cord blood Hcy levels, the difference is insignificant. Additionally, both MDA (r = 0.359, p < 0.001) and ROS (r = 0.473, p < 0.001) are positively correlated with cord blood Hcy level. The AUCs of MDA and ROS levels were 0.65 (95% CI: 0.60–0.69) and 0.88 (95% CI: 0.86–0.90), respectively, for predicting severe PE. Higher MDA and ROS levels are associated with increased risks of low Apgar score, admission to the NICU, and assisted ventilation for the newborn. Conclusion Increased levels of cord blood oxidative stress markers are significantly associated with negative effects on newborns. High cord blood Hcy levels might be involved in the observed elevated MDA and ROS concentrations in women with severe PE.

Introduction: Depression is associated with activation of innate immune response leading to oxidative damage. The 8-isoprostanes and 8-hydroxy-2-deoxyguanosine (8-OHdG) are biomarkers of oxidative damage to lipids and Deoxyribonucleic Acid (DNA), respectively. They have been independently linked to depression. Aim: To study the oxidative stress markers (8-Isoprostanes and 8-OHdG) in subjects with major depression. Materials and Methods: In this observational case-control study 42 cases of depression, 13-25 years of age were recruited from Psychiatry Out Patient Department (OPD) at a tertiary-care hospital in Delhi, India, along with 42 healthy controls. They were assessed clinically and using psychometric evaluation scores, Beck’s Depression Inventory-II (BDI-II) and Hamilton Depression Rating Scale (HAM-D). All 42 subjects were on medication with antidepressants {33/42 with Selective Serotonin Reuptake Inhibitors (SSRI) 8/42 with Tricyclic Antidepressants (TCA) and 1/42 on a combination of both}. Routine laboratory investigations were done. Plasma 8-Isoprostane and serum 8-OHdG concentrations were measured in both cases and controls. The results obtained were analysed using relevant statistical tests on STATA version 11 (StataCorp, 2009). Results: Clinically, all patients had moderate to severe depression. BDI-II and HAM-D scores were raised in all cases as compared to the controls (28.81±5.60 vs 1.62±1.59 for BDI and 20.88±4.67 vs 1.33±1.43 for HAM-D, respectively). The concentration (in depressed vs controls) of plasma 8-Isoprostane (107.70±54.48 pg/mL vs 77.78±60.15 pg/mL) and serum 8-OHdG (2103.03±154 pg/mL vs 2017±164.69 pg/mL) were significantly elevated (p-value <0.05). Though elevated in patients belonging to both genders, showed significant increase of 8-Isoprostane only in females and 8-OHdG only in males as compared to their healthy controls. No correlation of the levels of any of two markers was seen with clinical severity of depression of patients as assessed by BDI. Conclusion: Evidence of oxidative stress to lipids and DNA are present in the peripheral blood. These can be explored further in establishing the biomarkers for diagnosis and prognosis of depression.

Background:Cardiovascular disease (CV) is the most frequent cause of death in rheumatoid arthritis (RA) patients. It is well known that RA acts as an independent cardiovascular risk factor.Objectives:To assess the CV risk in RA patients using carotid ultrasonography (US) additionally to the traditional CV risk factors.Methods:A prospective transversal case control study was performed, including adult RA patients who fulfilled ACR/EULAR 2010 criteria and healthy controls matched according to CV risk factors. Population over 75 years old, patients with established CV disease and/or chronic kidney failure (from III stage) were excluded. The US evaluator was blinded to the case/control condition and evaluated the presence of plaques and the intima-media thickness. Statistical analysis was performed with R (3.6.1 version) and included a multivariate variance analysis (MANOVA) and a negative binomial regression adjusted by confounding factors (age, sex and CV risk factors).Results:A total of 200 cases and 111 healthy controls were included in the study. Demographical, clinical and US data are exposed in table 1. Not any difference was detected in terms of CV risk factors between the cases and controls. In both groups a relationship between age, BMI and high blood pressure was detected (p<0.001).Table 1.Table 2.RA basal characteristicsDisease duration (years)16,98 (11,38)Erosions (X-Ray of hands/feet)163 (81,5%)Seropositive (RF/anti-CCP)146 (73%)Extra-articular symptoms44 (22%)Intersticial difusse lung disease10 (5%)Rheumatoid nodules14 (7%)Prednisone use103 (51,5%)Median dose of Prednisone last year (mg)2,34 (2,84)sDMARDsMethotrexate104 (52%)Leflunomide29 (14,5%)Hydroxycloroquine9 (4,5%)bDMARDs89 (44,5%) TNFi41 (20,5%) Abatacept15 (7,5%) IL6i22 (11%) RTX11 (5,5%)JAKi26 (13%) Baricitinib11 (5,5%) Tofacitinib15 (7,5%)DAS 28-ESR3,1 (2,3, 3,9)SDAI7,85 (4,04, 13,41)HAQ0,88 (0,22, 1,5)RF (U/mL)51 (15, 164,25)Anti-CCP (U/mL)173 (22, 340)Patients showed higher intima-media (both right and left) thickness compared to controls (p<0.006). Moreover it was also related to the disease duration and DAS28 score (p<0.001). A higher plaque account was noted in cases(p<0.004) and it was also related to the disease duration (p<0.001).Conclusion:RA implies a higher CV risk. Traditional CV risk factors explains only partially the global risk. These findings support that RA acts as an independent cardiovascular risk factor.Disclosure of Interests:None declared

Citrullinated proteins have been suggested to play a critical role in the pathogenesis of multiple sclerosis (MS). Anticyclic citrullinated peptide (anti-CCP) antibody is used in the early diagnosis of rheumatoid arthritis (RA). The objective of this study was to investigate the presence of anti-CCP antibody in patients with MS compared to RA patients and healthy controls. Fifty patients with MS (38 females, 12 males; mean age 36.72 ± 8.82 years), 52 patients with RA (40 females, 12 males; mean age 40.87 ± 10.17 years), and 50 healthy controls (32 females, 18 males; mean age 38.22 ± 11.59 years) were included in this study. The levels of serum anti-CCP antibody were measured using an enzyme-linked immunosorbent assay (ELISA). The results of the study showed that anti-CCP antibody levels were significantly higher in RA patients versus MS or healthy controls(P<0.001). Moreover, anti-CCP antibody was positive in 43 (83%) patients with RA, while it was negative in all MS patients as well as in all healthy controls. Also, no significant correlation was found between the anti-CCP levels and EDSS scores(r=-0.250). In conclusion, the results of this study did not support a positive association between serum anti-CCP antibody and MS.
