          Abstract

          RESUMEN 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 % 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.

          ABSTRACT 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% 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.

            Intrapleural use of tissue plasminogen activator and DNase in pleural infection.

            More than 30% of patients with pleural infection either die or require surgery. Drainage of infected fluid is key to successful treatment, but intrapleural fibrinolytic therapy did not improve outcomes in an earlier, large, randomized trial. We conducted a blinded, 2-by-2 factorial trial in which 210 patients with pleural infection were randomly assigned to receive one of four study treatments for 3 days: double placebo, intrapleural tissue plasminogen activator (t-PA) and DNase, t-PA and placebo, or DNase and placebo. The primary outcome was the change in pleural opacity, measured as the percentage of the hemithorax occupied by effusion, on chest radiography on day 7 as compared with day 1. Secondary outcomes included referral for surgery, duration of hospital stay, and adverse events. The mean (±SD) change in pleural opacity was greater in the t-PA-DNase group than in the placebo group (-29.5±23.3% vs. -17.2±19.6%; difference, -7.9%; 95% confidence interval [CI], -13.4 to -2.4; P=0.005); the change observed with t-PA alone and with DNase alone (-17.2±24.3 and -14.7±16.4%, respectively) was not significantly different from that observed with placebo. The frequency of surgical referral at 3 months was lower in the t-PA-DNase group than in the placebo group (2 of 48 patients [4%] vs. 8 of 51 patients [16%]; odds ratio for surgical referral, 0.17; 95% CI, 0.03 to 0.87; P=0.03) but was greater in the DNase group (18 of 46 patients [39%]) than in the placebo group (odds ratio, 3.56; 95% CI, 1.30 to 9.75; P=0.01). Combined t-PA-DNase therapy was associated with a reduction in the hospital stay, as compared with placebo (difference, -6.7 days; 95% CI, -12.0 to -1.9; P=0.006); the hospital stay with either agent alone was not significantly different from that with placebo. The frequency of adverse events did not differ significantly among the groups. Intrapleural t-PA-DNase therapy improved fluid drainage in patients with pleural infection and reduced the frequency of surgical referral and the duration of the hospital stay. Treatment with DNase alone or t-PA alone was ineffective.
