Abstract Background: Pulmonary vascular damage may be associated with oxidative stress in congenital heart diseases. We investigated whether small ventricular septal defects have an effect on the pulmonary bed. Methods: This prospective cohort study included 100 patients with small ventricular septal defects and 75 healthy controls. Ischemia-modified albumin, high-sensitivity C-reactive protein, and various cardiovascular parameters were assessed in both groups. Results: The mean ischemia-modified albumin level was significantly higher in patients with small ventricular septal defects (0.62 ± 0.17 absorbance units) than in the control group (0.51 ± 0.09 absorbance units; p < 0.001). The mean high-sensitivity C-reactive protein level was significantly higher in the ventricular septal defects group (3.72 ± 1.57) than in the control group (2.45 ± 0.89; p < 0.001). The ischemia-modified albumin levels in patients with left ventricular internal diameter end diastole and end sistole and main pulmonary artery z-scores ≥ 2 were significantly higher than patients whose z-scores were <2. The ischemia-modified albumin and high-sensitivity C-reactive protein levels were positively correlated in the small ventricular septal defects group (rho = 0.742, p < 0.001). Receiver operating characteristic analyses showed that at the optimal cut-off value of ischemia-modified albumin for the prediction of pulmonary involvement was 0.55 absorbance units with a sensitivity of 60%, specificity of 62% (area under the curve = 0.690, p < 0.001). Conclusions: We demonstrated the presence of oxidative stress and higher ischemia-modified albumin levels in small ventricular septal defects, suggesting that ischemia-modified albumin might be a useful biomarker for evaluating the effects of small ventricular septal defects on the pulmonary bed.

Background: Inflammation plays a pivotal role in the pathogenesis of In-Stent Restenosis (ISR). High sensitivity C-reactive protein (hsCRP) is positively associated with major cardiovascular events. Aim: We aimed to investigate the hsCRP inflammatory response to Percutaneous Coronary Intervention (PCI) in Coronary Artery Disease (CAD) patients with coronary ISR vs. patients without ISR. Methods: This case-control study included 80 CAD patients previously treated with drug-eluting stent (DES) implantation. Patients had Coronary Angiography (CAG) because of chest pain or equivalent symptoms and were subdivided into 2 groups. Group A (n=40) included CAD patients with ISR. Group B (n=40) included age and gender-matched controls with CAD but without ISR. Serum hsCRP levels were obtained before PCI (baseline) and 8, 16, 24 h post-PCI. Results: At baseline (before intervention/CAG), the hsCRP level was increased in the ISR group compared with the No-ISR group (p=0.007). There were 36 (90%) patients in the ISR group who had a high hsCRP (>3 mg/L) compared with 25 (62.5%) patients in the No-ISR group. Also, there was a significant relationship between high hsCRP and the ISR. Patients with ISR had higher frequencies and percentages of elevated CRP than the no-ISR control group. This difference was maintained for all measurements, baseline, after 8, 16, and 24 h (p<0.05). Repeated measures analysis of variance (ANOVA) in the ISR group revealed that mean hsCRP differed significantly between serial measurements (p<0.001). In contrast, in the control group, the mean hsCRP did not differ significantly between the serial measurements (p=0.65). Most of our patients (n=66, 82.5%) had 1-vessel CAD disease, and the left anterior descending (LAD) coronary artery was significantly affected in 46 patients (57.5%). Management of restenosis was accomplished mainly by stenting by DES in 29 patients (72.5%). Conclusion: Patients with ISR had substantially higher pre- and post-PCI hsCRP levels than the no-ISR controls. This difference was maintained up to 24h post-PCI. Conversely, the mean hsCRP did not significantly differ at the follow-up points for the controls without ISR.

Introduction: Low sensitivity and specificity in traditional laboratory tests became insufficient for accurate diagnostics and initiation of proper treatment of patients infected with bacterial meningitis. High sensitivity C reactive protein (hsCRP) may be an appropriate supplement for rapid diagnosis of bacterial meningitis. The subject of our investigation was the determination of C- reactive protein in cerebrospinal fluid (CSF) duringacute bacterial meningitis.Methods: HsCRP was analysed by a sensitive immunoturbidimetric assay using the Dimension RxL analyser (Siemens). Cerebrospinal fluid concentrations of C-reactive protein have been measured in 20 patients(age range,1 to 50 years) presenting with acute bacterial meningitis and also in a non-infected, non-inflamed control group (n=25).Results: The accuracy and precision of the method proved to be satisfactory. Repeatability of serial sampling for hsCRP described by coefficient of variation were CV=2.1-4.5%. This assay hsCRP in cerebrospinal fluid demonstrates adequate performance characteristics for routine clinical use. Elevated levels of CRP were found in 95% patients with bacterial meningitis. The mean CRP value in 25 uninfected control group was 0.25 mg/L (range 0.10-0.55). The mean CRP for patients with bacterial meningitis was 21.4 mg/L (range 0.40-100).Conclusions: A sensitive assay for CRP in CSF would be an useful adjunct to conventional investigation of acute infective meningitis.

Information concerning the mechanisms underlying oxidative stress and low-grade inflammation in young healthy women predisposing eventually to future diseases is scarce. We investigated the relationship of oxidative stress and high-sensitivity C-reactive protein (hsCRP) in fertile-age women by oral combined contraceptive (OC) use. Caucasian Italian healthy non-obese women (n = 290; 100 OC-users; 190 non-OC-users; mean age 23.2 ± 4.7 years) were analyzed. Blood hydroperoxides, as oxidative stress biomarkers, were assessed by Free Oxygen Radical Test (FORT). Serum hsCRP was determined by an ultra-sensitive method (hsCRP). Markedly elevated oxidative stress (≥400 FORT Units) was found in 77.0% of OC-users and 1.6% of non-OC-users, odds ratio (OR) = 209, 95% CI = 60.9–715.4, p < 0.001. Elevated hsCRP levels ≥ 2.0 mg/L, considered risky for cardiovascular diseases (CVDs), were found in 41.0% of OC-users and 9.5% of non-OC-users, OR = 6.6, 95%CI 3.5–12.4, p < 0.001. Hydroperoxides were strongly positively correlated to hsCRP in all women (rs = 0.622, p < 0.001), in OC-users (rs = 0.442, p < 0.001), and in non-OC-users (rs = 0.426, p < 0.001). Women with hydroperoxides ≥ 400 FORT Units were eight times as likely to have hsCRP ≥ 2 mg/L. In non-OC-users only, hydroperoxides values were positively correlated with weight and body mass index, but negatively correlated with red meat, fish and chocolate consumption. Our research is the first finding a strong positive correlation of serum hydroperoxides with hsCRP, a marker of low-grade chronic inflammation, in young healthy women. Further research is needed to elucidate the potential role of these two biomarkers in OC-use associated side-effects, like thromboembolism and other CVDs.

BACKGROUND: The low inflammatory state that accompanies the Metabolic Syndrome (MetS) associates with the overexpression of oxidative stress. Ferritin and Transferrin serum are often used to measure iron status and their concentrations are altered in several metabolic conditions. We hypothesized that concentration of Ferritin and Transferrin serum increase in Metabolic Syndrome (MetS) and correlate with the inflammation and oxidative stress.METHODS: We studied 65 male MetS patients, aged 43.26±7.16 years. Iron metabolism was measured by concentration of Ferritin and Transferrin serums, while inflammatory and oxidative stress by high sensitivity C-reactive Protein (hsCRP) and F2-Isoprostane.RESULTS: Concentration of Ferritin 315.70±188.63 ng/L and Transferrin 2.36±0.31 g/L increased along with increasing components of MetS. Concentration of Ferritin serum had a positive correlation with hsCRP (r=0.220) and F2-Isoprostane (r=0.023).CONCLUSION: Serum concentration of Ferritin increased in the MetS and correlates with hsCRP and F2-Isoprostane.KEYWORDS: metabolic syndrome, ferritin, transferrin, hsCRP, F2-isoprostane

Objective: For several decades, there has been increasing evidence for excess incidence of lung cancer among workers in the rubber industry. The purpose of this study was to assess the risk of lung cancer occurrence among Egyptian workers involved in the rubber industry using two circulating protein biomarkers. Methods: This study was performed in a rubber manufacturing factory in Shubra El-Kheima region in Greater Cairo, Egypt. Environmental assessment for the suspended particulate matter of size 10 µm (PM10) concentrations was done. Levels of plasma pro-surfactant protein B (pro-SFTPB) and serum high-sensitivity C-reactive protein (HsCRP) were measured among the studied population ( n = 155) who were divided into two groups. The first group included 75 workers exposed to rubber manufacturing process while the control group involved 80 administrative subjects. Results: The levels of PM10 neither exceeded the Egyptian nor the international permissible limits where the highest levels were observed in the mixing department. However, through medical history and clinical examination, it was observed that some general and respiratory manifestations were more prevalent among the exposed group when compared with their controls. Laboratory investigations revealed that the mean values of pro-SFTPB and HsCRP levels among exposed workers were significantly higher than those of the control group. These increased circulating proteins levels were strongly and positively correlated with each other and with the duration of employment of exposed workers. Conclusion: The study results support the conclusion that prolonged occupational exposure to rubber manufacturing process is associated with an elevated risk of lung cancer.

Abstract Background Antioxidant/oxidant imbalance has been reported to be related to diminished ovarian reserve (DOR). Vitamin A (retinol), a kind of antioxidant, plays a role in restoring ovarian oxidative damage, while C-reactive protein (CRP) is the classical marker of oxidative stress and has recently been identified as an independent variable that is associated with low anti-Mullerian hormone (AMH) levels in young women with DOR. Additionally, retinol binding protein 4 (RBP4) can be considered a substitute for retinol in healthy, nonobese women. The study aim was to determine the relationship between serum RBP4, high sensitivity C-reactive protein (hs-CRP) concentrations and ovarian reserve in nonobese DOR patients. Methods This study included 24 DOR women and 48 normal ovarian reserve (NOR) women from the reproductive medical center of Renmin Hospital of Wuhan University. The serum RBP4 and high-sensitivity CRP (hs-CRP) levels were measured with ELISA kits. Results RBP4 levels (20,648.36 ± 5475.16 ng/ml vs 23,986.48 ± 5995.64 ng/ml, p = 0.025) were decreased, and hs-CRP levels (695.08 ± 1090.19 ng/ml vs 364.32 ± 786.29 ng/ml, p = 0.012) were increased in the DOR group. Serum RBP4 was positively related to AMH (Pearson r = 0.518, p = 0.000), while hs-CRP was negatively correlated with AMH (Spearman r = − 0.345, p = 0.005). after adjustments were made for the covariables, multiple line regression analysis showed that positive association between RBP4 and AMH still existed (β = 0.450, p < 0.001). Conclusion Decreased serum RBP4 levels and increased serum hs-CRP were observed in DOR patients in our study, and the strong correlation between RBP4 and AMH supports the notion that oxidative stress plays a role in DOR, and that appropriate levels of antioxidant vitamin A may be protective against ovarian reserve dysfunction.

Abstract Objectives To compare high sensitivity C-reactive protein (hsCRP) levels in children with type 1 diabetes, healthy controls, and children with obesity. Additionally, we aimed to analyze the association between hsCRP levels and glycemic control measured by glycohemoglobin A (HbA1c) and anthropometric and biochemical variables. Methods We conducted a non-randomized descriptive study of children with type 1 diabetes matched for sex and age with a control group and group with obesity. We recorded anthropometric parameters and studied variables related to diabetes, blood pressure, lipid profile, and HbA1c. HsCRP was measured by ELISA.Results We included 49 children with type 1 diabetes, 46 controls, and 40 children with obesity. hsCRP levels were significantly higher in the group with type 1 diabetes compared to controls and nearly significantly lower than in the group comprising children with obesity. We found no correlation between hsCRP and HbA1C and characteristics of type 1 diabetes with the exception of albuminin creatinine ratio (ACR). Statistically significant association was found between hsCRP and BMI and waist circumference Z-score. Conclusions Children with type 1 diabetes have a higher hsCRP than healthy subjects; this difference is not associated with HbA1c, but is related to waist circumference, BMI, and ACR. Obesity prevention should be a priority when performing follow-up in children with type 1 diabetes.

BACKGROUND: The prevalence of overactive bladder (OAB) appears to increase with age (aging), and free radicals most contribute to an increase in the aging process. But now, some researchers have found the efficacy of Morinda citrifolia in inhibiting the oxidative stress process so that it is expected to be beneficial for the treatment of OAB. AIM: The aim of this study was to find out the effect of M. citrifolia extract on overactive women bladder (OAB) through observation of high-sensitivity C-reactive protein (hs-CRP) urine level. METHODS: This research is an experimental study using double-blind randomized controlled trial design conducted at General Hospital H. Adam Malik Medan, USU Pharmacy Laboratory for extraction of noni fruit (M. citrifolia) and the Integrated Laboratory of Biochemical-Biomolecular USU Faculty of Medicine for the examination of hs-CRP urine levels. A t-dependent test is performed if data distribution is normally distributed or if not normally distributed, the median values are compared with the Mann–Whitney U-test. The effect of noni in hs-CRP levels performed by wilcoxon signed-Ranks Test. The statistical significance test with CI 95% and significant difference value p<0,05. RESULTS: These results indicate that the noni fruit extract has weak antioxidant activity (IC50 >150 ppm). From the statistical analysis, a significant difference (p < 0.05) was obtained in hs-CRP urine level after compared to before treatment. These results indicate that after treatment, there was an improvement in the degree of OAB symptom scores in Group A and Group B. CONCLUSIONS: Noni fruit extract (M. citrifolia) is proven to be able to inhibit oxidative stress in urothelium through observation of hs-CRP urine levels in overactive women bladder (OAB).
