Inflammatory Status

Introduction: Elevated serum C-reactive protein (CRP) can be a marker of disease activity involving inflammation, such as pregnancy complications and cardiovascular disease (CVD). Systemically high levels of CRP in women, including during pregnancy, may indicate higher risk for CVD. It is unknown if CRP measured during the pro-inflammatory state of pregnancy correlates with concentrations assessed 7-13 years after delivery. Hypothesis: Concentrations of CRP assessed during pregnancy will be related to CRP measured several years after pregnancy, independent of weight gain. Methods: We studied the first 252 women enrolled in the follow-up of the Pregnancy Outcomes and Community Health Study (POUCHmoms 2011-2013) with complete CRP data for the pregnancy (mean gestational age: 22.36 [2.22] weeks) and POUCHmoms visits (mean follow-up: 10.76 [1.38] years). The relative risk for high hsCRP (≥ 3.39 μg/ml) at the follow-up visit, related to quartiles of CRP during pregnancy, was examined using stepwise regression models. Results: Median (IQR) levels of pregnancy CRP and hsCRP at the follow-up visit were 5.68 [3.08, 9.76] and 3.39 [0.69, 9.73] μg/ml, respectively. Although absolute values of hsCRP at follow-up were generally lower than pregnancy CRP, 56% of women in the top and bottom quartiles of pregnancy CRP (71 of 126) were in the same quartile for hsCRP at follow-up (figure). The relative risk of having high hsCRP (≥ 3.39 μg/ml) at follow-up ranged from 2.7-5.2 for the 2 nd - 4 th quartiles of pregnancy CRP (vs. the 1st quartile). Controlling for pre-pregnancy BMI and follow-up weight change, the relative risk of having high hsCRP at follow-up was significantly higher for the 2 nd (1.15 [1.02-1.30]),3 rd (1.19 [1.05-1.35), and 4 th (1.22 [1.05-1.41]) quartiles of pregnancy CRP. Conclusions: Pregnancy CRP levels are related to hsCRP levels several years later in this cohort of women, even after adjusting for pre-pregnancy BMI and follow-up weight change. CRP assessed in pregnancy may reflect inflammatory status later in life.

Abstract Background This study aims to investigate the predictive value of biological and neuroimaging markers to determine incident frailty among older people for a period of 5 years. Methods We included 1394 adults aged 70 years and older from the Multidomain Alzheimer Preventive Trial, who were not frail at baseline (according to Fried’s criteria) and who had at least 1 post-baseline measurement of frailty. Participants who progressed to frailty during the 5-year follow-up were categorized as “incident frailty” and those who remained non-frail were categorized as “without frailty.” The differences of baseline biochemical factors (25-hydroxyvitamin D, homocysteine, omega-3 index, C-reactive protein), other biological markers (Apolipoprotein E genotypes, amyloid-β deposits), and neuroimaging data (gray matter volume, hippocampal volume, white matter hyperintensities) were compared between groups. Cox proportional hazard model was used to evaluate the associations between biomarkers and incident frailty. Results A total of 195 participants (14.0%) became frail over 5 years. Although 25-hydroxyvitamin D deficiency, homocysteine levels, low-grade inflammation (persistently increased C-reactive protein 3–10 mg/L), gray matter, and hippocampal volume were significantly associated with incident frailty in unadjusted models, these associations disappeared after adjustment for age, sex, and other confounders. Omega-3 index was the sole marker that presented a trend of association with incident frailty (hazard ratio: 0.92; 95% confidence interval: 0.83–1.01; p = .082). Conclusions This study failed to identify biomarkers able to predict frailty incidence in community-dwelling older adults for a period of 5 years. Further longitudinal research with multiple measurements of biomarkers and frailty is needed to evaluate the long-term relationships between changes in biomarkers levels and frailty evolution.

Background. Vitamin D deficiency is widespread throughout the world. Several reports have incriminated vitamin D deficiency as the cause of rickets, osteomalacia, and other chronic diseases. Recent studies have suggested a possible link between deficiency of 25-hydroxyvitamin D and dyslipidemia.Aim. To investigate the association between 25-hydroxyvitamin D deficiency and dyslipidemia in Indian subjects.Methodology. We recruited 150 asymptomatic consecutive subjects from patients’ attendees at the Departments of Neurology and Medicine in Yashoda Hospital, Hyderabad, India. Study period was from October 2011 to March 2012. All subjects underwent 25-hydroxyvitamin D assay by chemiluminescent microparticle immunoassay, fasting blood sugar and lipid profile, calcium, phosphorus, alkaline phosphatase, and C-reactive protein (CRP).Results. Out of 150 subjects, men were 82 (54.6%), and mean age was 49.4 (±15.6) years. Among risk factors, hypertension was noted in 63/150 (42%), 25-hydroxyvitamin D deficiency in 59/150 (39.3%), diabetes in 45/150 (30%), dyslipidemia in 60 (40%), smoking in 35/150 (23.3%), and alcoholism in 27/150 (18%). Deficiency of 25-hydroxyvitamin D was significantly associated with dyslipidemia (P=0.0001), mean serum glucose (P=0.0002) mean CRP (P=0.04), and mean alkaline phosphatase (P=0.01). Multivariate analysis showed that 25-hydroxyvitamin D deficiency was independently associated with dyslipidemia (odds ratio: 1.9; 95% CI : 1.1–3.5).Conclusions. We found that deficiency of 25-hydroxyvitamin D was independently associated with dyslipidemia in Indian subjects.
