RESUMO
INTRODUCTION: Pleural disease involves a large number of admissions and long hospital stays. In order to improve this situation, a Pleural Unit (PU) was created in our hospital. Our aim was to analyze the clinical impact of this unit. MATERIAL AND METHODS: In this prospective study, we included patients admitted to the PU of the Hospital Universitario Central de Asturias for primary spontaneous pneumothorax (PSP), secondary spontaneous pneumothorax (SSP), complicated parapneumonic pleural effusion (CPPE), and malignant pleural effusion (MPE) between January 2015 and December 2018. We analyzed descriptive parameters, mean length of stay, readmissions at 1 month, need for surgery, and in the CPPE group, in-hospital mortality. The data were compared with those of patients admitted to the respiratory medicine department for the same diseases during the previous two years (2013-2014). We also describe all procedures performed in the PU, in both inpatients and outpatients. RESULTS: A total of 741 patients were included, We observed a progressive decrease in total admissions for pleural diseases and mean length of stay (days) (with the exception of MPE), as follows: PSP: from 6.2 to 4.2 (P=.004); SSP: 13.2 to 8.6 (P=.005), MPE: 10.3 to 12.3 (P=.05); and CPPE: 18.3 to 11.3 (P=.001) There was a reduction in hospital readmissions at 1 month and in in-hospital mortality due to CPPE in the PU period (14.9% to 5.5%) (P=.021). CONCLUSIONS: The creation of a PU could decrease the number of unnecessary admissions, and reduce mean lengths of stay and, in the case of CPPE, in-hospital mortality.

Introducción: La inflamación de la pleura desencadenada por bacterias y mediada por citocinas, aumenta la permeabilidad vascular y produce vasodilatación, lo cual genera desequilibrio entre la producción de líquido pleural y su capacidad de reabsorción por eficientes mecanismos fisiológicos. La condición anterior conduce al desarrollo de derrame pleural paraneumónico. Objetivo: Exponer la importancia de la correlación fisiopatológica y diagnóstica con los pilares fundamentales de actuación terapéutica en el derrame pleural paraneumónico. Métodos: Revisión en PubMed y Google Scholar de artículos publicados hasta abril de 2021 que abordaran el derrame pleural paraneumónico, su fisiopatología, elementos diagnósticos, tanto clínicos como resultados del estudio del líquido pleural, pruebas de imágenes, y estrategias terapéuticas. Análisis y síntesis de la información: El progreso de una infección pulmonar y la producción de una invasión de gérmenes al espacio pleural favorece la activación de mecanismos que conllevan al acúmulo de fluido, depósito de fibrina y formación de septos. Este proceso patológico se traduce en manifestaciones clínicas, cambios en los valores citoquímicos y resultados microbiológicos en el líquido pleural, que acompañados de signos radiológicos y ecográficos en el tórax, guían la aplicación oportuna de los pilares de tratamiento del derrame pleural paraneumónico. Conclusiones: Ante un derrame pleural paraneumónico, con tabiques o partículas en suspensión en la ecografía de tórax, hallazgo de fibrina, líquido turbio o pus en el proceder de colocación del drenaje de tórax, resulta necesario iniciar fibrinólisis intrapleural. Cuando el tratamiento con fibrinolíticos intrapleurales falla, la cirugía video-toracoscópica es el procedimiento quirúrgico de elección(AU)
Introduction: The inflammation of the pleura triggered by bacteria and mediated by cytokines, increases vascular permeability and produces vasodilation, which generates imbalance between the production of pleural fluid and its resorption capacity by efficient physiological mechanisms. The above condition leads to the development of parapneumonic pleural effusion. Objective: To expose the importance of the pathophysiological and diagnostic correlation with the fundamental pillars of therapeutic action in parapneumonic pleural effusion. Methods: Review in PubMed and Google Scholar of articles published until April 2021 that addressed parapneumonic pleural effusion, its pathophysiology, diagnostic elements, both clinical and results of the pleural fluid study, imaging tests, and therapeutic strategies. Analysis and synthesis of information: The progress of a lung infection and the production of an invasion of germs into the pleural space favors the activation of mechanisms that lead to the accumulation of fluid, fibrin deposition and formation of septa. This pathological process results in clinical manifestations, changes in cytochemical values and microbiological results in the pleural fluid, which accompanied by radiological and ultrasound signs in the chest, guide the timely application of the pillars of treatment of parapneumonic pleural effusion. Conclusions: In the event of a parapneumonic pleural effusion, with septums or particles in suspension on chest ultrasound, finding fibrin, turbid fluid or pus in the procedure of placement of the chest drain, it is necessary to initiate intrapleural fibrinolytic. When treatment with intrapleural fibrinolytics fails, video-thoracoscopic surgery is the surgical procedure of choice(AU)

Introducción: El derrame pleural paraneumónico resulta la complicación más frecuente de la neumonía bacteriana, de manejo complejo y muchas veces quirúrgico. No existen publicaciones en Cuba provenientes de ensayos clínicos controlados y aleatorizados ni del uso de la estreptoquinasa recombinante (Heberkinasa®) en el derrame pleural. Objetivo: Evaluar la eficacia y la seguridad de la Heberkinasa® en el tratamiento del derrame pleural paraneumónico complicado complejo y el empiema en niños. Métodos: Ensayo clínico fase III, abierto, aleatorizado (2:1), en grupos paralelos y controlado. Se concluyó la inclusión prevista de 48 niños (1-18 años de edad), que cumplieron los criterios de selección. Los progenitores otorgaron el consentimiento informado. Los pacientes se distribuyeron en dos grupos: I- experimental: terapia estándar y administración intrapleural diaria de 200 000 UI de Heberkinasa® durante 3-5 días y II-control: tratamiento estándar. Las variables principales: necesidad de cirugía y la estadía hospitalaria. Se evaluaron los eventos adversos. Resultados: Ningún paciente del grupo I-experimental requirió cirugía, a diferencia del grupo II-control en el que 37,5 por ciento necesitó cirugía video-toracoscópica, con diferencia altamente significativa. Se redujo la estadía hospitalaria (en cuatro días), las complicaciones intratorácicas y las infecciones asociadas a la asistencia sanitaria en el grupo que recibió Heberkinasa®. No se presentaron eventos adversos graves atribuibles al producto. Conclusiones: La Heberkinasa® en el derrame pleural paraneumónico complicado complejo y empiema resultó eficaz y segura para la evacuación del foco séptico, con reducción de la necesidad de tratamiento quirúrgico, de la estadía hospitalaria y de las complicaciones, sin eventos adversos relacionados con su administración(AU)
Introduction: Paraneumonic pleural effusion is the most frequent complication of bacterial pneumonia, with complex and often surgical management. There are no publications in Cuba from randomized controlled clinical trials or the use of recombinant streptokinase (Heberkinase®) in pleural effusion. Objective: To evaluate the efficacy and safety of Heberkinase® in the treatment of complex complicated parapneumonic pleural effusion and empyema in children. Methods: Phase III, open-label, randomized (2:1), parallel-group, controlled clinical trial. The planned inclusion of 48 children (1-18 years of age), who met the selection criteria, was completed. Parents gave informed consent. The patients were divided into two groups: I-experimental: standard therapy and daily intrapleural administration of 200,000 IU of Heberkinase® for 3-5 days; and II-control: standard treatment. The main variables: need for surgery and hospital stay. Adverse events were evaluated. Results: No patient in group I-experimental required surgery, unlike group II-control in which 37.5 percent required video-assisted thoracoscopic surgery, with a highly significant difference. Hospital stay (to 4 days), intrathoracic complications and infections associated to healthcare in the group that received Heberkinase® was reduced. No serious adverse events attributable to the product occurred. Conclusions: Heberkinase® in complex complicated parapneumonic pleural effusion and empyema was effective and safe for the draining of the septic focus, with reduction of the need for surgical treatment, hospital stay and complications, with no adverse events related to its administration(AU)

Introducción: El derrame pleural paraneumónico es la enfermedad pleural más frecuente de la infancia, el 40-60 por ciento de los casos se presenta como complicación de neumonía adquirida en la comunidad. Ante la aparición de líquido pleural viscoso, con fibrina o tabiques, la fibrinólisis intrapleural aporta beneficios en la resolución de esta grave afección. Objetivo: Describir la evolución clínica e imagenológica de tres niños graves con derrame pleural paraneumónico complicado complejo y empiema. Presentación de casos: Pacientes ingresados en la Unidad de Terapia Intensiva del Hospital Pediátrico Provincial "Dr. Eduardo Agramonte Piña" con el diagnóstico de neumonía adquirida en la comunidad complicada con derrame pleural paraneumónico complicado complejo, tratados con estreptoquinasa recombinante por vía intrapleural; la primera paciente presentó crecimiento de Pseudomona en el cultivo de líquido pleural, patógeno no habitual en las infecciones respiratorias agudas procedentes de la comunidad. El segundo caso, se recibió complicada con shock séptico y el tercer paciente con ecografía torácica que mostró derrame pleural multitabicado, con grandes bolsones y gruesos tabiques. Los tres casos evolucionaron satisfactoriamente, sin necesidad de tratamiento quirúrgico, ni aparición de reacciones adversas atribuibles al fibrinolítico. Conclusiones: La administración intrapleural de la estreptoquinasa recombinante en niños graves con derrame pleural paraneumónico complicado complejo y empiema, resulta un método eficaz y seguro en la evacuación del foco séptico pleural, lo que favorece el control de la infección, sin aparición de complicaciones. Los casos presentados tuvieron evolución satisfactoria y en ninguno se produjo evento adverso relacionado con la administración de la estreptoquinasa recombinante intrapleural(AU)
Introduction: Parapneumonic pleural effusion is the most common pleural disease in childhood; 40-60 percent of cases occur as a complication of community-acquired pneumonia. Given the onset of viscous pleural fluid, with fibrin or septums, intra-pleural fibrinolysis provides benefits to solve this serious condition. Objective: Describe the clinical and imaging evolution of three seriously ill children with complex complicated parapneumonic pleural effusion and empyema. Case presentation: Patients admitted to the Intensive Therapy Unit of "Dr. Eduardo Agramonte Piña" Provincial Pediatric Hospital with the diagnosis of pneumonia acquired in the community worsen with complex complicated parapneumonic pleural effusion, and treated in the intrapleural way with recombinant streptokinase. The first patient showed growth of Pseudomona in the culture of pleural fluid, a pathogen which is not common in acute respiratory infections from the community. The second case was complicated with septic shock; and the third patient had a chest ultrasound that showed multi-sited pleural effusion, with large bags and thick septums. All three cases evolved satisfactorily, without needing surgical treatment, or having adverse reactions attributable to fibrinolytic ones. Conclusions: Intrapleural administration of recombinant streptokinase in seriously ill children with complex complicated parapneumonic pleural effusion and empyema is an effective and safe method in the evacuation of pleural septic focus, which favors infection control, without complications. The cases presented had satisfactory evolution and none of them occurred adversely related to the administration of intrapleural recombinant streptokinase(AU)

El empleo de fibrinolíticos intrapleurales es una acertada opción terapéutica. Objetivo: Evaluar la eficacia y seguridad de la utilización de la estreptoquinasa recombinante en el tratamiento del derrame pleural paraneumónico complicado complejo en niños. Métodos: Ensayo clínico confirmatorio fase III, monocentro, abierto, aleatorizado y controlado (RPCEC00000292), realizado entre septiembre 2018 - octubre 2019. Se incluyeron niños (1 - 18 años de edad), que cumplieron los criterios de selección, incluida la voluntariedad. Todos recibieron el tratamiento convencional establecido y se distribuyeron en dos grupos: I-experimental (estreptoquinasa recombinante, dosis diaria intrapleural de 200 000 UI, 3-5 días); II-control (terapia convencional). Las variables principales fueron: necesidad de cirugía y la estadía hospitalaria. Se evaluaron también los eventos adversos. Resultados: Se evaluaron 55 niños con la enfermedad referida, de ellos, 34 (61,8 por ciento) se incluyeron en el estudio. Ningún paciente del grupo experimental requirió cirugía, a diferencia del grupo control que lo requirió en 25 por ciento. Se redujo significativamente la estadía hospitalaria en el grupo que recibió estreptoquinasa recombinante. No se presentaron eventos adversos graves atribuibles al tratamiento experimental. Conclusiones: La estreptoquinasa recombinante administrada en el derrame pleural paraneumónico complicado complejo resultó un método eficaz y seguro para la evacuación del foco séptico, con un impacto positivo expresado en la reducción de complicaciones, la necesidad de tratamiento quirúrgico y la estadía hospitalaria, sin la ocurrencia de eventos adversos relacionados con su uso(AU)
in the community by the pediatric population represents a health problem in the world and in Cuba. The use of intrapleural fibrinolytics is a good therapeutic option. Objective: To evaluate the effectiveness and security of the use of recombinant streptokinase in the treatment of complex parapneumonic pleural efussion in children. Methods: Phase III confirmatory clinical trial, monocentric, open, randomized and controlled (RPCEC00000292) - named as DENIS study- carried out from September 2018 to October, 2019. There were included children (from 1 to 18 years old) that met the selection criteria including voluntariness. All of them received the established conventional treatment and were distributed in two groups: I- experimental (recombinant streptokinase, intrapleural daily dose of 200 000 UI, 3 - 5 days); II- control (conventional therapy). The main variables were need of surgery and hospital stay. There were also assessed the adverse events. Results: 55 children with the above mentioned disease were assessed; 34 of them (61.8 percent) were included in the study. Any of the patients of the experimental group required surgery, opposite to the control group that required it in a 25 percent. The hospital stay was significantly reduced in the group that had treatment with recombinant streptokinase. There were not any severe adverse events related to the experimental treatment. Conclusions: When recombinant streptokinase was administered in the complex parapneumonic pleural efussion resulted in an efficient and safe method for the elimination of the septic focus, with a positive impact expressed in the reduction of complications, the need of surgical treatment and the hospital stay without presenting related adverse events while using it(AU)

La acumulación de fluido purulento o la presencia de bacterias en la tinción de Gram en el líquido pleural se define como empiema, se puede desarrollar entre 2- 12 por ciento de los niños con neumonía, por lo general bacteriana. Evoluciona en tres fases, la exudativa, fibrinopurulenta y organizada. El cuadro clínico está dado por manifestaciones respiratorias con fiebre persistente y malestar general. Los estudios radiológicos son importantes para el diagnóstico y es el ultrasonido pleural la modalidad de imagen preferida pues confirma la presencia y volumen de fluido pleural, así como la existencia de septos o tabiques. El tratamiento se basa en antibioticoterapia y drenaje a través de una pleurostomía; si hay presencia de tabiques, esfacelos o el estudio bioquímico del líquido pleural informa pH /7; glucosa /2,2 mmol/L; LDH/ 1000 UI, se comienza con estreptoquinasa intrapleural. El tratamiento quirúrgico se indica si hay deterioro clínico y radiológico después de concluir el uso de fibrinolíticos, persistencia de sepsis asociada a colección pleural a pesar del drenaje, coraza de fibrina que impide la reexpansión pulmonar y fístula broncopleural con neumotórax. La mortalidad es baja(AU)
The accumulation of purulent fluids or the presence of bacteria in the Gram´s stain in the pleural liquid is defined as empyema. It can develop in the 2 to 12 percent of children with pneumonia, generally the bacterial one. It evolves in three phases: exudative, fibrinopurulent and organized. The clinical picture is a consequence of respiratory manifestations with persistent fever and general discomfort. The radiology studies are important for the diagnosis and the pleural ultrasound is the preferred imaging modality because it confirms the presence and volume of the pleural fluid, as well as the existence of septa. The treatment is based in the use of antibiotic therapy and the drainage through a pleurostomy; if there is presence of septa, slough or the biochemical study of the pleural liquid informs of pH/7, glucose /2.2 mmol/L, LDH / 1000 UI, so it is started the use of intrapleural streptokinase. The surgical treatment is indicated if there is a clinical and radiological worsening after finishing the use of fibrinolytics, persistence of sepsis associated to pleural collection in spite of the drainage, fibrin shell that hampers pulmonar reexpanding; and bronchopleural fistula with pneumothorax(AU)

Pleural infections have high morbidity and mortality, and their incidence in all age groups is growing worldwide. Not all infectious effusions are parapneumonic and, in such cases, the organisms found in the pleural space are not the same as those observed in lung parenchyma infections. The diagnostic difficulty lies in knowing whether an infectious effusion will evolve into a complicated effusion/empyema, as the diagnostic methods used for this purpose provide poor results. The mainstays of treatment are to establish an early diagnosis and to commence an antibiotic regimen and chest drain as soon as possible. This should preferably be carried out with fine tubes, due to certain morphological, bacteriological and biochemical characteristics of the pleural fluid. Fluid analysis, particularly pH, is the most reliable method for assessing evolution. In a subgroup of patients, fibrinolytics may help to improve recovery, and their combination with DNase has been found to obtain better results. If medical treatment fails and surgery is required, video-assisted thoracoscopic surgery (VATS) is, at least, comparable to decortication by thoracotomy, so should only undertaken if previous techniques have failed. Further clinical trials are needed to analyze factors that could affect the results obtained, in order to define new evidence-based diagnostic and therapeutic strategies that provide more effective, standardized management of this disease.

Analysis of pleural fluid can have, on its own, a high diagnostic value. In addition to thoracocentesis, a diagnostic hypothesis based on medical history, physical examination, blood analysis and imaging tests, the diagnostic effectiveness will significantly increase in order to establish a definite or high probable diagnosis in a substantial number of patients. Differentiating transudates from exudates by the classical Light's criteria helps knowing the pathogenic mechanism resulting in pleural effusion, and it is also useful for differential diagnosis purposes. An increased N-terminal pro-brain natriuretic peptide, both in the fluid and in blood, in a due clinical context, is highly suggestive of heart failure. The presence of an increased inflammatory marker, such as C-reactive protein, together with the presence of over 50% of neutrophils is highly suggestive of parapneumonic pleural effusion. If, in these cases, the pH is<7.20, then the likelihood of complicated pleural effusion is high. There remains to be demonstrated the usefulness of other markers to differentiate complicated from uncomplicated effusions. An adenosine deaminase > 45 U/L and>50% lymphocytes is suggestive of tuberculosis. If a malignant effusion is suspected but the cytological result is negative, increased concentrations of some markers in the pleural fluid can yield high specificity values. Increased levels of mesothelin and fibruline-3 are suggestive of mesothelioma. Immunohistochemical studies can be useful to differentiate reactive mesothelial cells, mesothelioma and metastatic adenocarcinoma. An inadequate use of the information provided by the analysis of pleural fluid would results in a high rate of undiagnosed effusions, which is unacceptable in current clinical practice.

Although during the last few years there have been several important changes in the diagnostic or therapeutic methods, pleural effusion is still one of the diseases that the respiratory specialist have to evaluate frequently. The aim of this paper is to update the knowledge about pleural effusions, rather than to review the causes of pleural diseases exhaustively. These recommendations have a longer extension for the subjects with a direct clinical usefulness, but a slight update of other pleural diseases has been also included. Among the main scientific advantages are included the thoracic ultrasonography, the intrapleural fibrinolytics, the pleurodesis agents, or the new pleural drainages techniques.

To describe the clinical and laboratory characteristics of parapneumonic pleural and empyema in children aged 1-14 years hospitalized at the HNDAC Department of Pediatrics from January 2007-December 2013. Materials and Methods: A descriptive, retrospective, cross-sectional study in patients from 1 month of age to 14 years and 11 months and 29 days, admitted to HNDAC Hospitalization Department of Pediatrics diagnosed with parapneumonic pleural effusion and/or empyema, from January 1st 2007 until December 31st 2013. Results: In the seven years of study there were 32 cases (74.4 per cent of total) of parapneumonic pleural effusion, and 11 (25.6 per cent) of empyema, with a prevalence of 1.1 per cent and 0.4 per cent respectively. The location of the empyema was on the left side, and in the effusion was on the right side. All cases had more than 4 days of evolution, fever range was between 39 and 40 degrees C. There was statistically significant difference in the average of number of days of hospitalization for the empyema, also the average value of leukocytes, banded neutrophils and CRP was significantly higher in these. In both groups the highest percentage of patients had leukocytes between 15000 and 25000, and most of the patients had CRP value higher or equal than 15. CRP pleural fluid culture was positive in 50 per cent of cases of empyema. Streptococcus pneumoniae was the most frequently isolated germ. The age group of 1-2 years was the most common in empyema, while in the parapneumonic pleural effusion was the group of 5-14 years. Conclusions: The prevalence of in children diagnosed with community-acquired pneumonia was 1.1 per cent, while in empyema, 0.4 per cent. In empyema was more common the left side, and the right side in parapneumonic pleural effusion. All cases had 5 or more days of sickness, and had fever (39.2 degrees C average in empyema, and 39.1 degrees C in parapneumonic pleural effusion), being the range of 39-40 degrees C...
