Faculty Opinions recommendation of Elevated maternal C-reactive protein and increased risk of schizophrenia in a national birth cohort.

BackgroundThere are no existing longitudinal studies of inflammatory markers and atopic disorders in childhood and risk of hypomanic symptoms in adulthood. This study examined if childhood: (1) serum interleukin-6 (IL-6) and C-reactive protein (CRP); and (2) asthma and/or eczema are associated with features of hypomania in young adulthood.MethodParticipants in the Avon Longitudinal Study of Parents and Children, a prospective general population UK birth cohort, had non-fasting blood samples for IL-6 and CRP measurement at the age of 9 years (n = 4645), and parents answered a question about doctor-diagnosed atopic illness before the age of 10 years (n = 7809). These participants completed the Hypomania Checklist at age 22 years (n = 3361).ResultsAfter adjusting for age, sex, ethnicity, socio-economic status, past psychological and behavioural problems, body mass index and maternal postnatal depression, participants in the top third of IL-6 values at 9 years, compared with the bottom third, had an increased risk of hypomanic symptoms by age 22 years [adjusted odds ratio 1.77, 95% confidence interval (CI) 1.10–2.85, p < 0.001]. Higher IL-6 levels in childhood were associated with adult hypomania features in a dose–response fashion. After further adjustment for depression at the age of 18 years this association remained (adjusted odds ratio 1.70, 95% CI 1.03–2.81, p = 0.038). There was no evidence of an association of hypomanic symptoms with CRP levels, asthma or eczema in childhood.ConclusionsHigher levels of systemic inflammatory marker IL-6 in childhood were associated with hypomanic symptoms in young adulthood, suggesting that inflammation may play a role in the pathophysiology of mania. Inflammatory pathways may be suitable targets for the prevention and intervention for bipolar disorder.

Longitudinal Association

AbstractFe deficiency (ID) defined as plasma ferritin <12 µg/l is associated with delayed cognitive development in early childhood and increased incidence of infections; however, the longitudinal association between early-life factors and ID in 18-month-old children in Denmark is unknown. The present study aimed to determine the prevalence of ID and to describe risk factors associated with ID in healthy 18-month-old Danish children. Blood samples, anthropometric measurements and self-reported questionnaire data had been obtained in the birth cohort, Odense Child Cohort. The questionnaires were modified from those used in the Danish National Birth Cohort. Plasma ferritin and C-reactive protein in venous, non-fasting samples were analysed in the final sample size of 370 children after exclusion of seventy-nine children due to chronic disease, acute infection, C-reactive protein >10 mg/l, twin birth or prematurity. Associations with ID were analysed by logistic regression, adjusting for sex, maternal education, duration of partial breast-feeding and current intake of milk, fish and meat. Overall, fifty-six children had ID (15·1 %). Factors associated with increased risk were exclusive breast-feeding beyond 4 months (OR 5·97; 95 % CI 1·63, 21·86) and no intake of oral Fe supplements from 6 to 12 months (OR 3·99, 95 % CI 1·33, 11·97. Duration of partial breast-feeding and current diet was not associated with ID. In conclusion, the ID prevalence was 15·1 %, and both exclusive breast-feeding beyond 4 months and no intake of oral Fe supplements from 6 to 12 months were associated with increased risk of ID in 18-month-old children.

Abstract Background: C-reactive protein (CRP), an acute-phase protein, is a sensitive systemic marker of inflammation and acute-phase reactions. Testing CRP concentrations at hospital admission may provide information about disease risk and overall survival. Methods: All first-ever transmittals to the department of medical and chemical laboratory diagnostics for determination of low-sensitivity CRP (n = 274 515, 44.5% male, median age 51 years) between January 1991 and July 2003 were included [median follow-up time: 4.4 years (interquartile range, 2.3–7.4 years)]. The primary endpoint was all-cause mortality. Multivariate Cox regression adjusted for sex and age was applied for analysis. Results: Compared to individuals within the reference category (CRP <5 mg/L), hazard ratios (HR) for all-cause mortality increased from 1.4 (5–10 mg/L category) to 3.3 in the highest category (>80 mg/L, all P <0.001). CRP was associated with various causes of death. The relation of CRP to cancer death was stronger than to vascular death. Younger patients with increased CRP had relatively far worse outcome than older patients (maximal HR: ≤30 years: 6.7 vs >60 years: 1.7–3.7). Interestingly, both short- and long-term mortality were associated with increasing CRP concentrations (>80 mg/L: HR 22.8 vs 1.4). Conclusion: Measurement of low-sensitivity CRP at hospital admission allowed for the identification of patients at increased risk of unfavorable outcome. Our findings indicate that close attention should be paid to hospitalized patients with high CRP not only because of very substantial short-term risk, but also long-term excess risk, the basis for which needs to be determined.

Our aim was to prospectively assess the prognostic value of beta2- microglobulin (b2-M) in patients with acute pulmonary embolism (PE). We conducted a prospective study of 109 patients admitted in a pulmonary clinic due to acute PE. A panel of inflammatory markers including b2-M white blood cell (WBC) count and C-reactive protein (CRP) was determined for each patient. In this preliminary study, baseline b2-M levels significantly correlated with the impairment of oxygenation and with all the parameters that are used for the early risk stratification of patients. In multivariate analysis, patients’ age and baseline b2-M levels were significantly associated with an increased risk of death. These findings require further prospective validation.

Background: Proprotein convertase subtilisin/kexin type 9 (PCSK9) is a promising target for lowering plasma low-density lipoprotein cholesterol and preventing cardiovascular (CV) disease. Whether plasma PCSK9 measured during the acute phase predicts recurrent CV events in patients with acute myocardial infarction (AMI) remains unresolved. Methods and Results: Plasma PCSK9 levels were measured in 1,646 patients with AMI from the China PEACE-Prospective AMI Study at the acute phase. Additionally, 248 patients were resampled and measured at 1 month post-AMI. Associations of acute-phase PCSK9 tertiles with clinical characteristics and recurrent CV events within 1 year were assessed. Female gender (OR 1.94, 95% CI 1.24–3.03), premature coronary heart disease (CHD; OR 2.12, 95% CI 1.37–3.26), higher high-sensitivity C-reactive protein (OR 1.67, 95% CI 1.44–1.95), and higher triglycerides (OR 1.46, 95% CI 1.03–2.09) were associated with higher baseline PCSK9. Plasma PCSK9 levels in the highest tertile (versus lowest) did not have an increased risk of 1-year recurrent CV events in the AMI cohort (HR 0.78, 95% CI 0.52–1.16) or any subgroup. There was also no association between percentage changes in PCSK9 over the first month and 1-year recurrent events, although there was a trend of differences between patients in the upper versus lower tertiles. Conclusion: Plasma PCSK9 levels measured during the acute phase were associated with high-sensitivity C-reactive protein, triglycerides, premature CHD, and gender in patients with AMI but did not predict recurrent CV events within 1 year. Dynamic changes in PCSK9 suggested a trend yet no significance value in predicting recurrent CV events.

Background: High levels of C-reactive protein (CRP) are associated with cardiovascular disease, diabetes and mortality. It is unclear whether changes in CRP or persistently high CRP are associated with these outcomes beyond the baseline measure. Methods: We conducted a prospective cohort analysis of 10,229 participants from the ARIC Study with two measurements of CRP six years apart (at visits 2 and 4, 1990-92 and 1996-98, respectively). CRP was categorized into two groups using a standard cut-point for defining high levels (≥3 vs. <3 mg/L). Six-year change in CRP was categorized as: persistently not high (<3 mg/L), decreasing (≥3 to <3 mg/L), increasing (<3 to ≥3 mg/L), and persistently high (≥3 mg/L). Cox proportional hazards models were used to assess the association between visit 2 CRP, visit 4 CRP and six-year change in CRP and each of the following outcomes from visit 4 through 2010: diabetes, coronary heart disease, ischemic stroke, heart failure and all-cause mortality. Models were adjusted for traditional risk factors at visit 2. Sensitivity analyses additionally adjusted for visit 4 covariates. Results: Persons with CRP ≥3 mg/L at visit 2 or 4 had higher risk of each outcome compared to those with CRP <3 mg/L ( Table ). We observed higher risk of all outcomes in persons with persistently high CRP, and of all outcomes except stroke in persons with increasing CRP, compared to those with CRP <3 mg/L at both visits ( Table ). Persons whose CRP decreased from high to <3 mg/L did not have significantly increased risk of cardiovascular outcomes or diabetes compared to those with CRP persistently <3 mg/L. Results were similar after adjusting for visit 4 covariates. Conclusions: Persons with sustained high levels of CRP or whose CRP increased to high levels had higher risk of diabetes, cardiovascular disease, and death, while those whose levels decreased from high to moderate or low were at lower risk. Multiple measures of CRP may better characterize inflammatory status and provide more comprehensive information regarding long-term risk.

Objective: The aim of this study was to determine the independent value of N-terminal pro b-type natriuretic peptide, high-sensitivity cardiac troponin T, and C-reactive protein to predict onset of cardiopulmonary disease in a large, multi-center systemic sclerosis cohort followed prospectively. Methods: Subjects from the Canadian Scleroderma Research Group registry with data on N-terminal pro b-type natriuretic peptide, high-sensitivity cardiac troponin T, and C-reactive protein were identified. Outcomes of interest were death, systolic dysfunction (left ventricular ejection fraction < 50% or medications for heart failure), pulmonary arterial hypertension by right heart catheterization, pulmonary hypertension by cardiac echocardiography (systolic pulmonary artery pressures ⩾ 45 mmHg), arrhythmias (pacemaker/implantable cardiac defibrillator or anti-arrhythmic medications), and interstitial lung disease. Multivariate Cox proportional hazard models were generated for each outcome. Results: A total of 675 subjects were included with a mean follow-up of 3.0 ± 1.8 years. Subjects were predominantly women (88.4%) with mean age of 58.2 ± 11.3 years and mean disease duration of 13.7 ± 9.1 years. One hundred and one (101, 15%) subjects died during follow-up, 37 (6.4 %) developed systolic dysfunction, 18 (2.9%) arrhythmias, 34 (5.1%) pulmonary arterial hypertension, 43 (7.3%) pulmonary hypertension, and 48 (12.3%) interstitial lung disease. In multivariate analyses, elevated levels of N-terminal pro b-type natriuretic peptide, high-sensitivity cardiac troponin T, and C-reactive protein were associated with increased risk of death, while elevated levels of N-terminal pro b-type natriuretic peptide and C-reactive protein were associated with increased risk of developing pulmonary hypertension. Conclusion: In systemic sclerosis, N-terminal pro b-type natriuretic peptide, high-sensitivity cardiac troponin T, and C-reactive protein have independent predictive value for death and pulmonary hypertension. A larger study would be required to determine the predictive value of these biomarkers for less common systemic sclerosis outcomes.

Background: Elevation in the ratio of triglyceride to high-density lipoprotein cholesterol (TG/HDL-C) has been suggested as a marker of insulin resistance (IR), conferring an increased risk of atherosclerosis in these patients. The association between TG/HDL-C and coronary artery calcification (CAC) measured by computed tomography has yet to be established. The goal of this study was to examine the relationship between IR, as determined by TG/HDL-C ≥ 3.5, and significant CAC (absolute score ≥ 100). Methods: Fasting lipid levels, homocysteine, C reactive protein and lipoprotein (a) levels of 336 asymptomatic individuals, who also underwent electron beam tomography (EBT), were measured. Results: The mean age of participants was 55 ±10 years. 71.7% were male. 37.4% had hypertension, 52.5% had hypercholesterolemia, 12.4% had diabetes mellitus (DM) and 52.5% had family history of premature CHD. Individuals with IR had higher significant CAC (≥100) than those without IR (70% vs. 27%, P=0.0001). After adjustment for age, gender, hypertension, hypercholesterolemia and DM, multivariate regression analysis demonstrated that individuals with IR had more significant CAC (odds ratio 2.1, 95% CI=1.1–3.9, p=0.01). Further sub-analysis revealed that individuals with IR had significantly higher lipoprotein (a) (Lp(a)) than those without IR (odds ratio 1.31, 95% CI=1.09-.16, p=0.03). No significant differences in C-reactive protein (CRP) and homocysteine were found between the two groups. Conclusion: Insulin resistance, as measured by TG/HDL-C ≥ 3.5, was associated with a significantly higher incidence of accelerated atherosclerosis on EBT (absolute CAC score ≥ 100), independent of age, gender and conventional risk factors. IR was also significantly associated with elevated levels of Lp(a). Further studies regarding the clinical significance of insulin resistance and elevated CAC score, as well as its association with Lp(a), may be warranted.
