Background: Vitamin A is important for the immune system, and might suppress inflammatory activity in multiple sclerosis (MS). Objectives: We aimed to examine if vitamin A levels were associated with MS risk in samples collected prospectively and during gestation. Methods: We measured Retinol Binding Protein (RBP – a surrogate marker for vitamin A) and high-sensitivity C-reactive protein (hs-CRP) levels, in (1) prospectively collected biobank blood samples from MS cases and controls, and (2) gestational samples where the offspring had later developed MS, and gestational control samples. The risk of MS was calculated using matched multivariable logistic regression adjusted for confounders. Results: In prospective samples, RBP levels within the second quintile (vs. the first) were associated with a lower MS risk (OR = 0.38, 95% CI 0.19–0.74). No effect on MS risk in the offspring by gestational RBP levels was found. In young subjects hs-CRP levels ≥10 mg/l in prospective samples were associated with a lower MS risk (OR = 0.36, 95% CI 0.14–0.95). Conclusions: Our results suggest that sub-optimal vitamin A levels may be associated with MS risk. The association between hs-CRP levels and MS risk in young subjects may support the role of the hygiene hypothesis in MS aetiology.

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.

617 Background: Serum levels of interleukine-6 and C-reactive protein are significatively higher in patients with neoplastic conditions. Therefore, the determination of high-sensitivity C-reactive protein (hs-PCR) has been widely used as a surrogate marker for chronic elevation of circulating cytokines. Increased hs-CRP concentrations have been reported in many conditions, in particular in patients with cardiovascular diseases, obesity, diabetes, autoimmunity, inflammatory bowel diseases and cancer risk. Some authors, on the basis of these findings, have encouraged further studies to clarify the etiologic and prognostic role of the aforementioned test. Our study has been conducted in patients enrolled in the phase III prospective multicentric randomized “Italian Trial in Advanced Colorectal Cancer (ITACa),” in order to assess hs-CRP levels at diagnosis and their significance with respect to overall survival (OS) and progresion free survival. Methods: Peripheral blood samples from 133 consecutive patients were collected into EDTA tubes. The collection was obtained before the beginning of first line chemotherapy. The supernatant was immediately transfer into a cryovial and stored at –80°C. Samples were thawed and hs-CRP has been measured with Cobas c501 analyzer. Results: Levels of hs-CRP >13.1 mg/L were associated with a worse median PFS, 8.9 months (95% CI 6.8-9.6) vs. 12.1 months (95% CI 9.3-14.9) in patients with levels <13.1 mg/L (p<0.0001). Similarly, levels >13.1 mg/L were associated with worse median OS, 14.4 (95% CI 11.5-17.1) vs. 28.8 (95% CI 24.3-36.6) in patients with a concentration <13.1 mg/L (p<0.0001). In multivariate analysis, hs-PCR adjusted for baseline factors including age (<70, ≥70 years), gender, ECOG perfomance status (0,1-2), tumor localization (rectum, colon), stage at diagnosis (I-III, IV), CT regimen (Folfiri, Folfox), KRAS status (wild type, mutant), site of metastases (liver, other metastases), was found to be independently associated with PFS and OS. Conclusions: Our study demonstrates the prognostic value of hs-CRP in patients with metastatic carcinoma of the colon and rectum.

Objective: To review the role of elevated C - reactive protein (CRP) as a marker for predicting the development of Peripheral Arterial Disease (PAD). Methods: An online search was conducted using the most trusted medical data base PubMed and the articles published in peer-reviewed journals within the last 5 years (from the year 2005 to date) to collect evidence about the association of C-reactive protein with Peripheral Arterial Disease, using keywords like C-reactive protein, hs-C-reactive protein, inflammation, atherogenesis, peripheral arterial disease and their combinations. Out of 240 articles shown during online search on PubMed, only 17 articles related to the role of CRP and High sensitivity CRP (hs-CRP) as a marker in PAD. Results: 17 articles based on the role of CRP and High sensitivity CRP (hs-CRP) as a marker in PAD were studied and evaluated thoroughly working on their study design and outcomes. Almost all the 17 studies showed strong association hs-CRP with PAD. The results are described in the form of a table. Conclusion: CRP seems to be a marker of severity of PAD and it may serve as a strong prognostic indicator.

ABSTRACT Introduction Chronic obstructive pulmonary disease (COPD) is a major cause of morbidity and mortality throughout the world. By 2020, the World Health Organization predicts that COPD will become the third leading cause of death and the fifth leading cause of disability worldwide. The COPD is a complex disease characterized by slowly progressive and largely irreversible airflow obstruction due to chronic bronchitis and emphysema and associated with systemic inflammation. Objective This study aimed to correlate the plasma levels of high-sensitivity C-reactive protein (hs-CRP) with severity of COPD and pulmonary function tests [PFTs; according to Global Initiative for Chronic Obstructive Lung Disease (GOLD) stages] and find out the relation between hs-CRP levels and clinical parameters of age, number of pack years, and body mass index (BMI) of the patient. Materials and methods A cross-sectional study of 102 male patients with clinically and spirometrically diagnosed cases of COPD was performed. Data on patient's demographic characteristics, pack years, BMI, PFTs, and hs-CRP were analyzed. Results A total of 76 of the patients had moderate airflow obstruction (GOLD stages II and III), mild airflow obstruction was present in 14 patients (GOLD stage I), and 12 patients had severe airflow obstruction (GOLD stage IV). The hs-CRP was normal in 6 patients, while it was raised in 96 patients. The value of hs-CRP was correlated with age, pack years, BMI, and GOLD stages. There was a significant negative correlation between hs-CRP and BMI and a significant positive correlation between hs-CRP and age, pack years, and GOLD stages. Conclusion A raised level of CRP in COPD indicates reduced lung function; it plays an important role in systemic inflammation. This study supports the role of hs-CRP as a simple, cost-effective biochemical marker in the staging and determining the severity of COPD other than spirometry.

This study examined the association between depression symptoms and metabolic syndrome (MetS) or its components prospectively. It assessed the mediator role of high-sensitivity C-reactive protein (hs-CRP) and intracellular adhesion molecule-1 (ICAM-1). Self-reported depression symptoms were assessed using the Center for Epidemiologic Studies-Depression scale. MetS was defined as having at least three of the following five criteria: (1) waist circumference >102 centimeters (cm) in men or >88 cm in women; (2) triglycerides ≥ 50 milligrams per deciliter (mg/dL); (3) high-density lipoprotein cholesterol <40 mg/dL in men or <50 mg/dL in women; (4) blood pressure: systolic ≥ 30 and diastolic ≥85 mm of mercury or on antihypertensive medication; and (5) fasting glucose ≥110 mg/dL. The risk ratios (RR) with 95% confidence interval (CI) were estimated using multivariate Poisson regression models. A total of 419 White and 180 Black individuals with a mean age of 36 years were followed for 6.9 years. The findings demonstrated that hs-CRP mediated the influence of depression symptoms on central obesity in White young adults. The adjusted RR for central obesity was 1.08 with 95% CI of 0.88–1.32, and the value for hs-CRP was 1.12 with 95% CI of 1.02–1.23. Although depression did not influence MetS in this study cohort, the complete mediator role of hs-CRP was established for central obesity, a component of MetS in White young adults.

Asthma is a chronic inflammatory condition, and the main features include airway hyper-responsiveness and inflammation of the airway with the accumulation of inflammatory cells. Increased level of plasma fibrinogen and serum amyloid A suggests the involvement of systemic inflammation in asthma. C-reactive protein (CRP) is an acute-phase protein that produced mainly by hepatocytes and is an inflammatory marker. CRP levels monitoring is useful in the evaluation of early inflammation and efficacy of treatment in acute-phase illnesses. Several studies show that asthma alone can cause an increase in high-sensitivity CRP (hs-CRP) when compared with the healthy controls. Besides that, steroid-naïve patients have a higher mean value of hs-CRP levels compared with those on inhaled corticosteroid. Furthermore, studies have shown that an elevated hs-CRP level has a positive correlation with non-atopic asthma but not atopic asthma. Additionally, an increase in serum hs-CRP levels correlates with the severity of asthma. Therefore, serum hs-CRP is a useful surrogate marker to predict the severity of inflammation of the bronchus in asthma and assess the asthma status.

Coronary Heart Disease (CHD) is a disorder of the cardiovascular system, characterized by atherosclerotic lesions. Inflammation is a strong predictor for coronary heart disease. High sensitivity C-Reactive Protein (hs-CRP) is an important biomarker, synthesized in the liver, can predict the severity of CHD. If the hs-CRP level is found to be low 3 mg / L, a person has the potential for severe vascular risk. Therefore, hs-CRP can be used as a predictor of primary CHD prevention, especially if the hs-CRP level is still low.
