Complete Epstein-Barr virus seropositivity in a large cohort of patients with early multiple sclerosis
OBJECTIVE: To determine the prevalence of antibodies to Epstein-Barr virus (EBV) in a large cohort of patients with early multiple sclerosis (MS). METHODS: Serum samples were collected from 901 patients with a clinically isolated syndrome (CIS) or early relapsing-remitting multiple sclerosis (RRMS) participating in the German National MS cohort, a prospective cohort of patients with early MS with stringent inclusion criteria. Epstein-Barr nuclear antigen (EBNA)-1 and viral capsid antigen (VCA) antibodies were measured in diluted sera by chemiluminescence immunoassays (CLIAs). Sera of EBNA-1 and VCA antibody-negative patients were retested undiluted by an EBV IgG immunoblot. For comparison, we retrospectively analysed the EBV seroprevalence across different age cohorts, ranging from 0 to >80 years, in a large hospital population (N=16 163) from Berlin/Northern Germany. RESULTS: EBNA-1 antibodies were detected by CLIA in 839 of 901 patients with CIS/RRMS. Of the 62 patients without EBNA-1 antibodies, 45 had antibodies to VCA as detected by CLIA. In all of the remaining 17 patients, antibodies to EBV were detected by immunoblot. Altogether, 901 of 901 (100%) patients with CIS/RRMS were EBV-seropositive. EBV seropositivity increased with age in the hospital population but did not reach 100% in any of the investigated age cohorts. CONCLUSION: The complete EBV seropositivity in this large cohort of patients with early MS strengthens the evidence for a role of EBV in MS. It also suggests that a negative EBV serology in patients with suspected inflammatory central nervous system disease should alert clinicians to consider diagnoses other than MS
Treatment choices and neuropsychological symptoms of a large cohort of early MS
Objective To assess clinical characteristics, distribution of disease-modifying treatments (DMTs), and neuropsychological symptoms in a large cohort of patients with early-stage MS. Methods The German National MS Cohort is a multicenter prospective longitudinal cohort study that has recruited DMT-naive patients with clinically isolated syndrome (CIS) and relapsing-remitting MS (RRMS) since 2010. We evaluated their baseline characteristics and the prevalence of neuropsychological symptoms. Results Of 1,124 patients, with a 2.2: 1 female-to-male ratio and median age at onset of 31.71 years (interquartile range [IQR]: 26.06-40.33), 44.6% and 55.3% had CIS and RRMS, respectively. The median Expanded Disability Status Scale (EDSS) score at baseline was 1.5 (IQR: 1.0-2.0). A proportion of 67.8% of patients started DMT after a median time of 167.0 days (IQR 90.0-377.5) since the first manifestation. A total of 64.7% and 70.4% of the 762 patients receiving early DMT were classified as CIS and RRMS, respectively. Fatigue, depressive symptoms, and cognitive dysfunction were detected in 36.5%, 33.5%, and 14.7% of patients, respectively. Conclusion Baseline characteristics of this large cohort of patients with early, untreated MS corroborated with other cohorts. Most patients received early DMT within the first year after disease onset, irrespective of a CIS or RRMS diagnosis. Despite the low EDSS score, neuropsychological symptoms affected a relevant proportion of patients

Biological Burden of Adverse Childhood Experiences in Children
ObjectiveThis study aimed to examine relationships between adverse childhood experiences (ACEs) and related life events and allostatic load (AL)-"wear and tear" from chronic stress-in a pediatric population.MethodsChildren were screened with the PEdiatric ACEs and Related Life Event Screener (PEARLS) tool, a 17-item questionnaire capturing experiences of abuse, neglect, household challenges, and related life events. Biological data were available for 207 participants, and AL was operationalized using clinical or empirical cutoff points across 4 physiological systems (i.e., cardiac, metabolic, inflammatory, neurologic). Covariate-adjusted multivariable regression models were used to examine associations between AL with adversity and health.ResultsChildren (mean age = 6.5 years, range = 1-11 years) had an average AL score of 1.9 (standard deviation = 1.7), and a U-shaped relationship was observed with child's age. Continuous PEARLS and original ACE scores were not associated with AL. However, children with a reported PEARLS score of 1 to 2 or original ACEs score of 1 to 3 had 1.5 (incidence rate ratio [IRR] = 1.50, 95% confidence interval [CI] = 1.09-2.08) and 1.4 (IRR = 1.41, 95% CI = 1.08-1.84) times greater AL, respectively, compared with participants with none reported. In secondary analyses, caregiver mental illness was associated with higher child AL (adjusted IRR = 1.27, 95% CI = 1.01-1.58). AL was also associated with poorer perceived child general health (adjusted β = -0.87, 95% CI = -1.58 to -0.15) and greater odds of child obesity (adjusted odds ratio = 1.51, 95% CI = 1.23-1.89).ConclusionsMeasuring AL in a pediatric population requires careful consideration of age. Higher AL was associated with a greater number of reported adversities and worse child health

Linkage and Association Analysis Identifies TRAF1 Influencing Common Carotid Intima-Media Thickness
Background and Purpose-Carotid intima-media thickness is a marker for subclinical atherosclerosis that predicts subsequent clinical cardiovascular events. The aim of this study was to identify chromosomal loci with linkage or association to common carotid intima-media thickness. Methods-Nuclear families were recruited using the single parental proband sib-pair design. Genotype data were available for 546 individuals from 132 nuclear families of the Bonn IMT Family Study using the Affymetrix GeneChip Human Mapping 250K Sty chip. Multipoint logarithm of the odds (LOD) scores were determined with the quantitative trait locus statistic implemented in multipoint engine for rapid likelihood. Linkage analysis and family-based association tests were conducted. Data from 2471 German participants from the HNR (Heinz Nixdorf Recall) Study were used for subsequent replication. Results-Two new genomic regions with suggestive linkage (LOD>2) were identified on chromosome 4 (LOD=2.26) and on chromosome 17 (LOD=2.01). Previously reported linkage findings were replicated on chromosomes 13 and 14. Fifteen single nucleotide polymorhisms, located on chromosomes 4, 6, and 9, revealed P<10(-4) in the family-based association analyses. One of these signals was replicated in HNR (rs2416804, 1-sided P=1.60x10(-3), located in the gene TRAF1). Conclusions-This study presents the first genome-wide linkage and association study of common carotid intima-media thickness in the German population. Alleles of rs2416804 in TRAF1 were identified as being linked and associated with carotid intima-media thickness. Further studies are needed to evaluate the contribution of this locus to the development of atherosclerosis
