RESUMO

BACKGROUND: Recently, anecdotal evidence suggested an increase in infective endocarditis (IE) in Manitoba driven by an increasing proportion of patients with intravenous drug use (IVDU)-associated endocarditis. This study aimed to characterize the observed changing incidence and epidemiology of IE. METHODS: This retrospective study evaluated consecutive patients >18 years old with an International Classification of Disease-10 diagnosis of IE who presented to a tertiary referral center in Winnipeg, Manitoba between January 1, 2004 and December 31, 2018. Data were obtained by individual review of paper and electronic medical records and entered into the Research Electronic Data Capture database. Mortality and hospital readmission data were acquired by linking Research Electronic Data Capture data to the Manitoba Centre for Health Policy, which prospectively maintains a comprehensive population-based health database. RESULTS: A total of 612 cases of IE were identified. The incidence of IE increased from 2.03 per 100,000 in 2004 to 5.16 per 100,000 in 2018, with IVDU-associated cases increasing from 0.11 to 2.87 per 100,000. Left heart vegetations were most common in the non-IVDU group, whereas right-sided vegetations dominated in the IVDU group. All-cause mortality did not differ between IVDU and non-IVDU IE, despite a significantly younger age in patients with IVDU. The IVDU group showed a higher rate of endocarditis recurrence. CONCLUSIONS: In this first study to examine the longitudinal incidence of IE in Manitoba, we showed that the incidence of IE has significantly increased over the last 15 years, with a contribution of IVDU-associated IE that has a high rate of mortality and disease recurrence.


INTRODUCTION: Des données anecdotiques récentes montraient une augmentation de l'endocardite infectieuse (EI) au Manitoba attribuable à la proportion accrue de patients atteints d'une endocardite associée à l'usage de drogues par voie intraveineuse (UDVI). La présente étude avait pour but de caractériser les changements observés dans l'incidence et l'épidémiologie de l'EI. MÉTHODES: Cette étude rétrospective a permis d'évaluer les patients consécutifs > 18 ans qui avaient un diagnostic d'EI conformément à la Classification internationale des maladies, 10e révision, et qui s'étaient présentés dans un centre d'aiguillage en soins tertiaires de Winnipeg, au Manitoba, entre le 1er janvier 2004 et le 31 décembre 2018. Nous avons obtenu les données par l'examen du dossier individuel et des dossiers médicaux électroniques de la base de données Research Electronic Data Capture. Nous avons obtenu les données sur la mortalité et les réadmissions à l'hôpital par la liaison des données de la Research Electronic Data Capture au Manitoba Centre for Health Policy, qui maintient de manière prospective une base de données exhaustive sur la santé de la population. RÉSULTATS: Nous avons trouvé un total de 612 cas d'EI. L'incidence de l'EI est passée de 2,03 par 100 000 en 2004 à 5,16 par 100 000 en 2018, et l'incidence des cas d'EI associée à l'UDVI, de 0,11 à 2,87 par 100 000. Les végétations du cœur gauche étaient plus fréquentes dans le groupe de patients atteints d'une EI non associée à l'UDVI, alors que les végétations du cœur droit dominaient dans le groupe de patients atteints d'une EI associée à l'UDVI. La mortalité toutes causes confondues ne différait pas entre les patients atteints d'une EI associée à l'UDVI ou non associée à l'UDVI, en dépit de l'âge significativement plus jeune des patients atteints d'une EI associée à l'UDVI. Le groupe de patients atteints d'une EI associée à l'UDVI montrait un taux plus élevé de récurrence de l'endocardite. CONCLUSIONS: Dans cette première étude, qui portait sur l'incidence longitudinale de l'EI au Manitoba, nous avons montré que l'incidence de l'EI avait considérablement augmenté au cours des 15 dernières années, puisque l'EI associée à l'UDVI a contribué à l'augmentation du taux de mortalité et de récurrence de la maladie.

RESUMO

INTRODUCTION: Obesity during pregnancy is associated with meta-inflammation and an increased likelihood of clinical complications. Surgery results in intense, acute inflammatory responses in any individual. Because obese individuals exhibit constitutive inflammatory responses and high rates of Caesarian section, it is important to understand the impact of surgery in such populations. Whether more pronounced pro-inflammatory cytokine responses and/or counterbalancing changes in anti-inflammatory immune modulators occurs is unknown. Here we investigated innate immune capacity in vivo and in vitro in non-obese, term-pregnant controls versus healthy, term-pregnant obese women (Class II, BMI 35-40). METHODS: Systemic in vivo induction of eleven pro- and anti-inflammatory biomarkers and acute phase proteins was assessed in plasma immediately prior to and again following Caesarian section surgery. Independently, innate immune capacity was examined by stimulating freshly isolated PBMC in vitro with a panel of defined PRR-ligands for TLR4, TLR8, TLR3, and RLR 24 h post-surgery. RESULTS: The kinetics and magnitude of the in vivo inflammatory responses examined were indistinguishable in the two populations across the broad range of biomarkers examined, despite the fact that obese women had higher baseline inflammatory status. Deliberate in vitro stimulation with a range of PRR ligands also elicited pro- and anti-inflammatory cytokine responses that were indistinguishable between control and obese mothers. CONCLUSIONS: Acute in vivo innate immune responses to C-section, as well as subsequent in vitro stimulation with a panel of microbial mimics, are not detectably altered in Class II obese women. The data argue that while Class II obesity is undesirable, it has minimal impact on the in vivo inflammatory response, or innate immunomodulatory capacity, in women selecting C-section.
