RESUMO

Introducción: La incidencia del derrame pleural paraneumónico, incluyendo el empiema, ha sufrido variaciones en las últimas décadas, que se han relacionado con la implantación de distintos tipos de vacuna antineumocócica conjugada. Métodos: Se han revisado retrospectivamente los datos de los 10 hospitales públicos de la provincia de Alicante (España), que abarcan una población de 279.000 niños menores de 15 años, entre 2010 y 2018. Se desglosaron los derrames menores de 10mm (DP−) y los de 10mm o más (DP+). Resultados: Se han analizado 366 episodios de derrame pleural paraneumónico, 178 DP− (48,6%) y 188 DP+ (51,4%), con una mediana de edad de 4 años (rango intercuartílico: 2-7 años) y una evidente estacionalidad con máximo en invierno y mínimo en verano. Se identificó al agente etiológico por cultivo en 34 pacientes (9,3%), destacando Streptococcus pneumoniae (24 pacientes) seguido por Streptococcus pyogenes (7 pacientes). El serotipo de S. pneumoniae más frecuente fue el 19A (6 pacientes) y se han identificado 3 fallos vacunales. La tasa anual media de incidencia fue de 14,3 casos por 100.000 menores de 15 años (7,0 para DP− y 7,3 para DP+), sin cambios significativos a lo largo del tiempo, aunque sí se apreciaron diferencias marcadas de la incidencia entre los distintos departamentos sanitarios. Conclusiones: No hemos encontrado variaciones temporales en la incidencia del derrame paraneumónico pese a la implementación de la vacuna antineumocócica conjugada de 13 serotipos. Es destacable la variabilidad de la incidencia entre departamentos vecinos sin motivo aparente.(AU)


Introduction: The reported incidence of parapneumonic pleural effusion, including empyema, has shown fluctuations in the last decades. It has been related to the implementation of different types of conjugate pneumococcal vaccines. Methods: We have retrospectively reviewed data from all 10 public hospitals in Alicante Province (Spain) covering a population of 279,000 children under 15 years of age, between 2010 and 2018. Effusions less than 10mm (PE−) and those of 10mm or more (PE+) were separated. Results: A total of 366 episodes of parapneumonic pleural effusion have been analyzed, 178 PE− (48.6%) and 188 PE+ (51.4%), with a median age of 4 years (interquartile range: 2-7 years) and marked seasonality with the maximum in winter and the minimum in summer. A culture proven bacterial agent was identified in 34 patients (9.3%), mainly Streptococcus pneumoniae (24 patients) followed by Streptococcus pyogenes (7 patients). The most frequent S. pneumoniae serotype was 19A (6 patients) and 3 vaccine failures were observed. The mean annual incidence rate was 14.3 cases per 100,000 children under 15 years of age (7.0 for PE− and 7.3 for PE+). No significant changes were observed in incidence over time, but noticeable differences in incidence were observed in different health departments. Conclusions: We have not found temporal variations in incidence of parapneumonic effusion despite the implementation of the 13-valent pneumococcal conjugate vaccine. The unexplained disparity in incidence between close departments is noteworthy.(AU)

RESUMO

Introduction: The most appropriate treatment for parapneumonic effusion (PPE), including empyema, is controversial. We analyzed the experience of our center and the hospitals in its reference area after adopting a more conservative approach that reduced the use of chest tube pleural drainage (CTPD). Methods: Review of the clinical documentation of all PPE patients in nine hospitals from 2010 to 2018. Results: A total of 318 episodes of PPE were reviewed; 157 had a thickness of <10 mm. The remaining 161 were 10 mm or thicker and were subdivided into three increasing sizes: PE+1, PE+2, and PE+3. There was a strong relationship between the size of the effusion and complicated effusion/empyema, defined by its appearance on imaging studies or by the physical or bacteriological characteristics of the pleural fluid. The size of effusion was also strongly related to the duration of fever and intravenous treatment and was the best independent predictor of the length of hospital stay (LHS) (p < 0.001). CTPD was placed in 2.9% of PE+1 patients, 19.3% of PE+2, and 63.9% of PE+3 (p < 0.001). The referral of patients with PE+1 decreased over time (p = 0.033), as did the use of CTPD in the combined PE+1/PE+2 group (p = 0.018), without affecting LHS (p = 0.814). There were no changes in the use of CTPD in the PE+3 group (p = 0.721). Conclusions: The size of the PPE is strongly correlated with its severity and with LHS. Most patients can be treated with antibiotics alone.
