ABSTRACT
Background: Traumatic brain injury (TBI) is a public health problem with a high burden in terms of disability and death. Infections are a common complication, with respiratory infections being the most frequent. Most available studies have addressed the impact of ventilator-associated pneumonia (VAP) after TBI; therefore, we aim to characterize the hospital impact of a broader entity, lower respiratory tract infections (LRTIs). Methods: This observational, retrospective, single-center cohort study describes the clinical features and risk factors associated with LRTIs in patients with TBI admitted to an intensive care unit (ICU). We used bivariate and multivariate logistic regressions to identify the risk factors associated with developing LRTI and determine its impact on hospital mortality. Results: We included 291 patients, of whom 77% (225/291) were men. The median (IQR) age was 38 years (28-52 years). The most common cause of injury was road traffic accidents 72% (210/291), followed by falls 18% (52/291) and assault at 3% (9/291). The median (IQR) Glasgow Coma Scale (GCS) score on admission was 9 (6-14), and 47% (136/291) were classified as severe TBI, 13% (37/291) as moderate TBI, and 40% (114/291) as mild TBI. The median (IQR) injury severity score (ISS) was 24 (16-30). Nearly 48% (141/291) of patients presented at least one infection during hospitalization, and from those, 77% (109/141) were classified as LRTIs, which included tracheitis 55% (61/109), ventilator-associated pneumonia (VAP) 34% (37/109), and hospital-acquired pneumoniae (HAP) 19% (21/109). After multivariable analysis, the following variables were significantly associated with LRTIs: age (OR 1.1, 95% CI 1.01-1.2), severe TBI (OR 2.7, 95% CI 1.1-6.9), AIS thorax (OR 1.4, 95 CI 1.1-1.8), and mechanical ventilation on admission (OR 3.7, 95% CI 1.1-13.5). At the same time, hospital mortality did not differ between groups (LRTI 18.6% vs. No LRTI 20.1%, p = 0.7), and ICU and hospital length of stay (LOS) were longer in the LRTI group (median [IQR] 12 [9-17] vs. 5 [3-9], p < 0.01) and (median [IQR] 21 [13-33] vs. 10 [5-18], p = 0.01), respectively. Time on the ventilator was longer for those with LRTIs. Conclusion: The most common site/location of infection in patients with TBI admitted to ICU is respiratory. Age, severe TBI, thoracic trauma, and mechanical ventilation were identified as potential risk factors. LRTI was associated with prolonged ICU, hospital stay, and more days on a ventilator, but not with mortality.
ABSTRACT
Background: Guillain-Barre syndrome is a polyradiculoneuropathy that has been associated with infectious diseases as triggers. There is currently little medical evidence exploring the relationship between the development of Guillain-Barre syndrome caused by SARS-CoV-2 infection and long Covid. Objective: To synthesize the medical evidence that describes the relationship between post Covid syndrome and Guillain-Barre syndrome in the paediatric population. Methodology: A scoping review was developed using Scopus and PubMed databases, including analytical and/or descriptive experimental and observational studies. Results: The main clinical manifestations presented by paediatric patients were distal and ascending weakness in the lower limbs and myalgia. The diagnostic approach was based on clinical findings, imaging findings on spinal magnetic resonance and electromyography. The therapeutic strategy is based on the use of intravenous human immunoglobulins. Conclusion: Guillain-Barre syndrome is a frequent disease in the paediatric population with active SARS-CoV-2 infection or in survivors, however, it is necessary to encourage further clinical studies that increase the medical literature that describes this association.
Introducción: El síndrome de Guillain-Barré es una polirradiculoneuropatía que se ha asociado con enfermedades infecciosas como desencadenantes. En la actualidad es escasa la evidencia médica que explore la relación entre el desarrollo del síndrome de Guillain-Barré causado por la infección por SARS-CoV-2 y la COVID prolongada. Objetivo: Sintetizar la evidencia médica que describe la relación entre el síndrome pos-COVID y el síndrome de Guillain-Barré en la población pediátrica. Metodología: Se realizó una revisión exploratoria utilizando las bases de datos de Scopus y PubMed, incluyendo estudios experimentales y observacionales analíticos o descriptivos. Resultados: Las principales manifestaciones clínicas presentadas por los pacientes fueron debilidad distal y ascendente en miembros inferiores y mialgias. El enfoque diagnóstico se apoyó en los hallazgos clínicos, hallazgos imagenológicos por resonancia magnética de columna y electromiografía. La estrategia terapéutica se basó en el uso de inmunoglobulinas humanas intravenosas. Conclusión: El síndrome de Guillain-Barré es una enfermedad frecuente en la población pediátrica con infección activa por SARS-CoV-2 o en sobrevivientes, sin embargo, es necesario incentivar el desarrollo de estudios clínicos que incrementen la literatura médica que describe esta asociación.
