RESUMO

OBJETIVO: Determinar el papel de los niveles plasmáticos de procalcitonina (PCT) en el diagnóstico de neumonía asociada a ventilación mecánica. Diseño Revisión sistemática y metaanálisis de los trabajos originales que evalúan el papel de PCT en el diagnóstico de neumonía asociada a ventilación mecánica. La búsqueda de trabajos se llevó a cabo en Medline, Embase, Colaboración Cochrane y MEDION y tras revisión de las referencias de los artículos obtenidos. Se extrajeron datos que permitieron el cálculo de la sensibilidad, la especificidad, las razones de verosimilitud y la odds ratio diagnóstica. Intervención: Metarregresión para determinar si la exposición a tratamiento antibiótico previo, el tiempo de desarrollo de neumonía y el tipo de paciente crítico tienen impacto en el rendimiento diagnóstico de la procalcitonina. RESULTADOS: Se incluyeron 7 estudios (373 pacientes, 434 episodios). No encontramos sesgos de publicación ni efecto umbral. Las cifras elevadas de PCT plasmática se asocian a un mayor riesgo de padecer neumonía (OR 8,39; IC 95% 5,4-12,6). Los datos agrupados de sensibilidad, especificidad, razón de verosimilitud positiva y negativa y odds ratio diagnóstica encontrados son, respectivamente, 76% (69-82), 79% (74-84), 4,35 (2,48-7,62), 0,26 (0,15-0,46) y 17,9 (10,1-31,7). El rendimiento diagnóstico se ve modificado por la exposición previa a antibióticos (rORD0,11, 0,02-0,069), no así por el tipo de paciente crítico o el tiempo de desarrollo de neumonía. CONCLUSIONES: Nuestros resultados muestran que la PCT aporta información adicional respecto al riesgo de sufrir neumonía asociada a ventilación mecánica. Su inclusión en los algoritmos diagnósticos podría mejorar la capacidad de los mismos


OBJECTIVE: To determine the role of plasma procalcitonin (PCT) levels in diagnosing ventilator associated pneumonia. DESIGN: A systematic review of publications prospectively assessing the diagnostic role of PCT in ventilator-associated pneumonia was carried out. The search was performed using Medline, Embase, the Cochrane Collaboration and MEDION, with reviewing of the references of retrieved articles. We extracted data that allowed the calculation of sensitivity, specificity, like lihoodratios and diagnostic odds ratio. Intervention Metaregression was performed to determine whether exposure to previous antibiotic treatment, the time to occurrence of ventilator-associated pneumonia and the type of patients had an impact upon the diagnostic performance of procalcitonin. RESULTS: Seven studies were considered (373 patients, 434 episodes). We found no publication bias or threshold effect. High plasma PCT levels were associated to an increased risk of suffering ventilator-associated pneumonia (OR: 8.39; 95% CI: 5.4-12.6). The pooled data on sensitivity, specificity, positive and negative likelihood ratio, and diagnostic odds ratio found were 76% (69-82), 79% (74-84), 4.35 (2.48-7.62), 0.26 (0.15-0.46) and 17.9 (10.1-31.7), respectively. Diagnostic yield was modified by prior exposure to antibiotics (rDOR 0.11, 0.02-0.069),but not by the type of critically ill patient or the time to occurrence of ventilator-associated pneumonia. CONCLUSIONS: Our results suggest that PCT provides additional information on the risk of VAP. Inclusion of PCT in diagnostic algorithms could improve their effectiveness

RESUMO

La Neisseria meningitidis serogrupo W-135 está implicada en casos aislados de meningitis aguda en nuestro país. Se describe el caso de una paciente de origen estadounidense, que ingresa por un cuadro compatible con meningitis aguda, aislándose en el cultivo de LCR N. meningitidis del serotipo W-135, comprobándose posteriormente la existencia de un déficit de la fracción C1q del complemento


The Neisseria meningitidis serogroup W-135 has been involved in isolated cases of acute meningitis here in Spain. There is described the case of one American-born patient who is admitted with clinical manifestations of acute meningitis, and with N. meningitidis serotype W-135 being isolated in cerebrospinal fluid (CSF) culture. Complement fraction C1q deficiency is later verified
