Maternal serum highly sensitive C-reactive protein in normal pregnancy and pre-eclampsia.
ABSTRACT To establish reference values for highly sensitive C-reactive protein (hsCRP) in normal pregnancy and determine whether disease severity could be predicted by serum hsCRP concentration in women with severe pre-eclampsia (PE).
Blood samples were collected from 25 pregnant women with severe PE and 202 healthy pregnant women who were divided into 4 groups by pregnancy duration. Levels of hsCRP were determined by the immunonephelometric method. Mean arterial pressure, time between delivery and diuresis, and mean ratio of systolic to diastolic blood flow velocity in uterine arteries were used as indicators of the severity of PE.
The median values of hsCRP in each group were 0.76 mg/L (0.16-13.61 mg/L), 1.53 mg/L (0.39-20.31 mg/L), 2.08 mg/L (0.50-9.45 mg/L), and 2.28 mg/L (0.44-8.11 mg/L) and showed a trend toward increase. Serum levels of hsCRP were positively correlated with each severity indicator of PE.
This study showed that hsCRP levels were positively correlated to pregnancy duration in healthy women and could be used as a severity marker in women with severe PE.

ABSTRACT: To assess a maternal serum level of high sensitive C-reactive protein (hs-CRP) as a useful clinical parameter in prediction of pre-eclampsia severity and, to evaluate the correlation between hs-CRP and body mass index (BMI). Using cross-sectional study design, CRP was measured by a high sensitive immunoturbidimetric method between 24 and 40 weeks of gestation in normotensive controls (n = 115), in mild (n = 63) and severe (n = 34) pre-eclamptic patients. The receiver operating characteristic analysis was used to estimate the optimal threshold score of hs-CRP. For disease severity evaluation, a hs-CRP concentration of 9.66 mg/L was determined as cut-off point with 88% sensitivity, 81% specificity, 71% positive predictive value and 92% negative predictive value. When all three groups of patients were adjusted for gestational age [24(°/7) -27,(6/7) 28(°/7) -33,(6/7) 34(°/7) -40(6/7) ] and BMI, hs-CRP levels of severe pre-eclamptic patients were significantly higher than mild ones and controls in the study group with BMI < 25 kg/m(2) (P < 0.001). In the study group with BMI ≥ 25 kg/m(2), only severe pre-eclamptic patients between 28(°/7) and 33(6/7) weeks of gestation had significantly higher hs-CRP levels when compared with control and mild pre-eclamptic group (P < 0.001). When the patients were subgrouped as high (≥ 9.66 mg/L) and low hs-CRP group (< 9.66 mg/L), adverse outcomes for hemolysis, elevated liver enzymes, and low platelet count (HELLP) syndrome and intrauterine growth-restricted baby were statistically significant higher in high hs-CRP group (P = 0.004 and P < 0.001, respectively). Elevated level of hs-CRP is a useful parameter in the severity of clinical risk of pre-eclampsia in patients with BMI < 25 kg/m(2) at third trimester.Journal of Obstetrics and Gynaecology Research 10/2010; 36(5):970-7. · 0.84 Impact Factor

ABSTRACT: Limited data are available on the presence of a systemic measure of inflammation in asthma. One marker that has been reported is C-reactive protein (CRP). To examine the correlation between high-sensitivity CRP (hsCRP) and asthma activity. Fifty-four patients with physician-diagnosed asthma, ages 6 to 58 years, were enrolled in the study. In addition to medical history and physical examination, asthma was assessed according to the National Asthma Education and Prevention Program (NAEPP) control score, fractional exhaled nitric oxide (FeNO), and spirometry. The relationships between hsCRP and each of the asthma control measures (ie, NAEPP control scores, presence of wheeze, FeNO, and forced expiratory volume in 1 second [FEV1]) were calculated. The hsCRP levels in all patients ranged from less than 0.5 to 14.1 mg/L, with a mean (SD) of 2.1 (2.9 mg/L), compared with less than 0.5 mg/L expected in healthy individuals. The FEV1 percentage predicted ranged from 48% to 130%, with a mean (SD) of 96.5% (17.5%). Correlation coefficients for hsCRP vs FEV1 and FeNO were 0.07 and -0.03, respectively. Neither of these values reached statistical significance. The chi2 analysis values for hsCRP vs the NAEPP scores, wheeze, FEV1, and FeNO were 0.00, 2.16, 1.32, and 2.08, respectively, with none being statistically significant. Our study of patients with asthma, mostly of a mild severity, did not reveal any significant correlation between hsCRP and wheeze, NAEPP control score, FEV1, or FeNO. Larger studies with a more diverse level of asthma control are warranted in examining the utility of hsCRP in the evaluation of asthma.Annals of allergy, asthma & immunology: official publication of the American College of Allergy, Asthma, & Immunology 06/2010; 104(6):485-9. · 3.45 Impact Factor

ABSTRACT: The aim of this study was to investigate C-reactive protein (CRP) level in preeclampsia (PE) and its association with the severity of the d isease. This cross-sectional study included 43 women with mild PE, 43 women with severe PE, and 43 healthy pregnant. They were selected in the third trimester of pregnancy in the Afzalipour Hospital, Kerman, Iran, from March 2006 to March 2007. Mean diastolic pressure and level of pr oteinuria were used as indicators of the sever- ity of the disease. The results were analyzed by t- test and spearman's rank correlation coefficient. Hemoglobin, aspartate and alanine transaminase, cre atinine and urine protein excretion, serum CRP, and alkaline phosphatase were higher in women with PE. There were significant correlations between serum CRP levels and diastolic blood pressure (r = 0.5, P = 0), urinary protein excretion (r = 0.5, P = 0), creatinine (r = 0.2, P = 0.003), spartate transaminase (r = 0.3, P = 0), alanine transaminase (r = 0.2, P = 0.006), and Hemoglobin (r = 0.2, P = 0.001). There were a negative cor- relation between serum CRP and weight of the new born (r = -0.09, P = 0.01) and gestational age in the time of delivery (r = -0.07, P = 0). We showed higher levels of CRP in women with PE. Elevated serum levels of CRP in PE women are, thus, correlated with severity of disease.01/2009;
