• The performance of Liaison in detecting acute Epstein-Barr infection is optimal in pediatric patients with compatible symptoms. • The optimal cutoff points obtained for the Liaison assay differed depending on the age range and symptomatic presentation. • Some autoantibodies such as ANCA or rheumatoid factor, and IgM against viruses like VHS or Cytomegalovirus, can cause cross-reactivity. • The use of Liaison is not recommended for protocol-driven manner in oncology patients and immunocompromised individuals. • Our data exclude the possibility of Epstein-Barr IgG antibodies causing cross-reactivity. The present investigation assessed the Liaison® diagnostic performance in detecting Epstein-Barr (EBV) IgM-VCA in a large patient cohort, considering age and symptomatology. VIDAS® were employed as a benchmark for acute EBV infection. The study also probed other coexisting conditions and potential cross-reactivity for error sources. A total of 1311 samples were analyzed, with notable associations found only among paediatric (kappa=0.75) and young adult (kappa=0.58) populations with compatible symptoms. ROC analysis revealed varying optimal cutoff values based on age and symptom categorizations. Logistic regression models identified age and patients from Oncology or Infectious Disease as significant factors for false positives. Potential interferences emerged with RF, ANCA, cytomegalovirus-IgM and VHS-IgM. Notably, Liaison® couldn´t distinguish EBV patients from Oncology, Haemathology or Internal Medicine. This study provides valuable insights, such as implementing ageand symptom-specific thresholds or reviewing test requests, for optimizing EBV serology in microbiology laboratories, leading to faster and more reliable responses.

Ictus. Infección nosocomial. Factores de riesgo. M ,Facultat de Medicina i Odontologia - Abstract
Fundamento y Objetivo: El ictus constituye una causa importante de mortalidad ydiscapacidad. El objetivo del presente estudio es identificar los factores predictores de infecciónnosocomial en la fase aguda del ictus y como ésta influye en la morbimortalidad de estaenfermedad.Pacientes y Métodos: Estudio prospectivo observacional longitudinal de cohortes depacientes con ictus agudo. El ictus se diagnosticó según la definición dada por la OrganizaciónMundial de la Salud (OMS) y actualizada por la Sociedad Española de Neurología (SEN). Lainfección nosocomial se definió por los criterios de los Center for Disease Control (CDC) y losde la Sociedad Española de Enfermedades Infecciosas y Microbiología Clínica (SEIMC).Resultados: Se incluyó a 258 pacientes con ictus agudo. De éstos, 102 (39,5%)presentaron al menos, una infección nosocomial (45,5% M; edad X 78,2 DE 9,7). La estanciamedia hospitalaria fue significativamente mayor en los pacientes infectados 14,9 días (8,4) queen los no infectados 8,4 días (5,6) (phabían tenido al menos una infección. Al realizar análisis de regresión logística se observó quela alteración en la deglución (OR 12,7; IC 95% 5,3-30,1; p(OR 4,5; IC 95% 1,7-12,3; p=0,003), la alteración del esfínter urinario (OR 2,9; IC 95% 1,3-6,4;p=0,009) y la diabetes mellitus (OR 2,3; IC 95% 1,1-4,7; p=0,03), se comportan comofactores predictores independientes que aumentan la probabilidad de infección nosocomial en elictus agudo. La escala de NIHSS >20 en el momento del ingreso (OR 17,3; IC 95% 5,1-59,5;pempeoramiento neurológico durante las primeras 24 horas (OR 11,6; IC 95% 3,6-37,2;padmisión (OR 6; IC 95% 1,5-25,6; p=0,015) son factores predictores independientes queaumentan la probabilidad de muerte en el ictus agudo. La escala de NIHSS>20 (OR 8,9; IC 95%2,7-29; p2,2-29,6%; p=0,002) y la alteración del control del esfínter urinario (OR 10,1; IC 95% 5-20,6;pfuncional al alta.Conclusiones: La disfagia, la afectación motora crural, la incontinencia urinaria y ladiabetes mellitus, son las variables clínicas que se identifican como factores de riesgoindependientes para la infección nosocomial en la fase aguda del ictus. Esta complicaciónmédica, sobre todo la infección respiratoria, aumenta significativamente la probabilidad demuerte de esta enfermedad., Background and Purpose: stroke is a very important cause of mortality and disability. Thisstudy has the objective to identify predictors factors and the clinical consequences ofnosocomial infection in acute stroke.Patients and Methods: we prospectively identified a consecutive cohort of patients who weeither admitted after an acute stroke. We used predefined diagnostic criteria by OMS and SENfor stroke and by CDC and SEIMC for infection.Results: 258 patients with acute stroke were included. 102 (39,5%) had at least one nosocomialinfection (45,5% M; edad X 78,2 DE 9,7). The mean hospital stay was 14,9 days (8,4) ininfection patients and 8,4 days (5,6) in no infection patients (p(71%) had at least one cause of infection. Using logistic regression analysis, the dysphagia (OR12,7; IC 95% 5,3-30,1; pinfection. Others factors are crural motor affectation (OR 4,5; IC 95% 1,7-12,3; p=0,003),urinary incontinence (OR 2,9; IC 95% 1,3-6,4; p=0,009) and diabetes mellitus (OR 2,3; IC 95%1,1-4,7; p=0,03). Baseline imbalance NIHSS >20 during the admission (OR 17,3; IC 95% 5,1-59,5; poutcome neurological during the first day (OR 11,6; IC 95% 3,6-37,2; p(OR 5,7; IC 95% 1,8-18,3; p=0,003) and the hyperglucemia in admission (OR 6; IC 95% 1,5-25,6; p=0,015), are the independients predictors factors that increasing the likelihood formortality in acute stroke. Baseline imbalance NIHSS >20 (OR 8,9; IC 95% 2,7-29; ppoor outcome neurological during the first day (OR 8,1; IC 95% 2,2-29,6%; p=0,002) and theurinary incontinence (OR 10,1; IC 95% 5-20,6; pfactors that increasing the likelihood of poor functional state in discharge.Conclusions: dysphagia, crural motor affectation, urinary incontinence and diabetes mellitusare the independients predictors factors that increasing the likelihood for nosocomial infectionin acute stroke. The chest infection increase significantly the likelihood of mortality during thehospital stay.
