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.
