Serum IgG titers against periodontal pathogens are associated with cerebral hemorrhage growth and 3-month outcome.

ABSTRACT: To assess the influence of periodontal disease on cerebral hemorrhage and its clinical course, we examined the association of the serum IgG titer of periodontal pathogens with hemorrhage growth and 3-month outcome. We consecutively enrolled 115 patients with acute cerebral hemorrhage (44 females, aged 71.3 ± 13.1 years) and used ELISA to evaluate the serum IgG titers of 9 periodontal pathogens: Porphyromonas gingivalis, Aggregatibacter (A.) actinomycetemcomitans, Prevotella intermedia, Prevotella nigrescens, Fusobacterium (F.) nucleatum, Treponema denticola, Tannerella forsythensis, Campylobacter rectus, and Eikenella corrodens. Significant hematoma growth was defined as an increase in the volume of >33% or an absolute increase in the volume of >12.5 mL. A poor outcome was defined as a 3 or higher on the modified Rankin Scale. We observed hemorrhage growth in 13 patients (11.3%). Multivariate analysis revealed that increased IgG titers of A. actinomycetemcomitans independently predicted the elevated hemorrhage growth (odds ratio 5.26, 95% confidence interval 1.52-18.25, p = 0.01). Notably, augmented IgG titers of F. nucleatum but not A. actinomycetemcomitans led to a poorer 3-month outcome (odds ratio 7.86, 95% confidence interval 1.08-57.08, p = 0.04). Thus, we demonstrate that elevated serum IgG titers of A. actinomycetemcomitans are an independent factor for predicting cerebral hemorrhage growth and that high serum IgG titers of F. nucleatum may predict a poor outcome in patients with this disease. Together, these novel data reveal how systemic periodontal pathogens may affect stroke patients, and, should, therefore, be taken into consideration in the management and treatment of these individuals.

Project description:INTRODUCTION:Periodontitis is a chronic inflammatory condition initiated by microorganisms and is positively linked to systemic conditions such as cancer, cardiovascular disease, and diabetes mellitus. OBJECTIVES:To prospectively investigate associations between empirically derived clusters of IgG antibodies against 19 selected periodontal microorganisms and cancer mortality in a representative sample of the US population. METHODS:We evaluated 6,491 participants aged ?40 y from the Third National Health and Nutrition Examination Survey (1988 to 1994), who had complete data on IgG antibody titers against 19 selected periodontal microorganisms and were free of cardiovascular disease and cancer. In a prior study, antibodies were categorized into 4 mutually exclusive groups via cluster analysis: red-green, orange-red, yellow-orange, and orange-blue. Cluster scores were estimated by summing z scores of the antibody titers making up each cluster. Participants were followed up to death until December 31, 2011. Cox proportional hazard models were applied to estimate hazard ratios (HRs) and 95% CIs for all-cancer mortality by tertiles of cluster scores. RESULTS:During follow-up for a median of 15.9 y, there were 2,702 deaths (31.3%), including 631 cancer-related deaths (8.1%). After adjusting for multiple confounders, the orange-blue cluster was inversely associated with cancer mortality (tertile 2 vs. tertile 1: HR = 0.67, 95% CI = 0.54 to 0.84; tertile 3 vs tertile 1: HR = 0.62, 95% CI = 0.46 to 0.84). The association between the yellow-orange cluster and all-cancer mortality was also inverse but not significant, and the orange-red cluster and the red-green cluster were not associated with all-cancer mortality. CONCLUSIONS:Antibodies against Eubacterium nodatum and Actinomyces naeslundii may be novel predictors of cancer mortality. If further studies establish a causal relationship between these antibodies and cancer mortality, they could be targets to prevent possible systemic effects of periodontal disease with potential interventions to raise their levels. KNOWLEDGE TRANSFER STATEMENT:Periodontal antibodies against Eubacterium nodatum and Actinomyces naeslundii were inversely associated with cancer mortality among adults followed up for an average of 16 y. Periodontal antibodies may predict cancer mortality.

Project description:BackgroundEvidence indicates that systolic blood pressure (SBP) reduction may reduce hematoma expansion in patients with intracerebral hemorrhage (ICH) who are initially seen with acute hypertensive response.ObjectiveTo explore the relationship between different variables of SBP reduction and hematoma expansion, perihematomal edema, and 3-month outcome among patients with ICH.DesignPost hoc analysis of a traditional phase 1 dose-escalation multicenter prospective study.SettingEmergency departments and intensive care units.PatientsPatients having ICH with an elevated SBP of at least 170 mm Hg who were seen within 6 hours of symptom onset.InterventionSystolic blood pressure reduction using intravenous nicardipine hydrochloride targeting 3 tiers of sequentially escalating SBP reduction goals (170-199, 140-169, or 110-139 mm Hg).Main outcome measuresWe evaluated the effect of SBP reduction (relative to initial SBP) on the following: hematoma expansion (defined as an increased intraparenchymal hemorrhage volume >33% on 24-hour vs baseline computed tomographic [CT] images), higher perihematomal edema ratio (defined as a >40% increased ratio of edema volume to hematoma volume on 24-hour vs baseline CT images), and poor 3-month outcome (defined as a modified Rankin scale score of 4-6).ResultsSixty patients (mean [SD] age, 62.0 [15.1] years; 34 men) were recruited (18, 20, and 22 patients in each of the 3 SBP reduction goal tiers). The median area under the curve (AUC) (calculated as the area between the hourly SBP measurements over 24 hours and the baseline SBP) was 1360 (minimum, 3643; maximum, 45) U. Comparing patients having less vs more aggressive SBP reduction based on 24-hour AUC analysis, frequencies were 32% vs 17% for hematoma expansion, 61% vs 40% for higher perihematomal edema ratio, and 46% vs 38% for poor 3-month outcome (P > .05 for all). The median SBP reductions were 54 mm Hg at 6 hours and 62 mm Hg at 6 hours from treatment initiation. Comparing patients having equal to or less vs more than the median SBP reduction at 2 hours, frequencies were 21% vs 31% for hematoma expansion, 42% vs 57% for higher perihematomal edema ratio, and 35% vs 48% for poor 3-month outcome (P > .05 for all).ConclusionsWe found no significant relationship between SBP reduction and any of the outcomes measured herein; however, the Antihypertensive Treatment of Acute Cerebral Hemorrhage study was primarily a safety study and was not powered for such end points. The consistent favorable direction of these associations supports further studies with an adequately powered randomized controlled design to evaluate the efficacy of aggressive pharmacologic SBP reduction.
