Study summary

The purpose of this prospective randomized clinical trial is to compare two currently accepted standard-of-care treatment strategies: Medical thoracoscopy as compared to instillation of intrapleural tissue Plasminogen Activator (TPA) and human recombinant Deoxyribonuclease (DNase) for the management of empyema or complicated parapneumonic effusion (CPPE) in adults.

Read the detailed description

Background: Pleural infection (empyema or complex parapneumonic effusion (CPPE)) represents one of the most common clinical diagnoses encountered in clinical practice in the United States (US) It is associated with substantial morbidity and mortality despite advances in medical diagnostic and therapeutic strategies.

Objective: Compare two standard of care treatments: TPA/DNase vs early medical Thoracoscopy

Methods: Investigators will conduct a prospective randomized clinical trial. Plan is to enroll total of 32 patients and randomize those patients to either Medical Thoracoscopy group or Fibrinolytic Therapy group.

Follow-up will be daily until hospital discharge and at 6 and 12 weeks in the outpatient setting

Potential Outcome and Benefit: Determine best strategy for treating patients with pleural infection

Study arms

  • Active comparator
    Fibrinolytic therapy group

    Patients randomized to the Fibrinolytic group will receive intrapleural therapy of combined tissue plasminogen activator (tPA) and human recombinant deoxyribonuclease (DNase) via chest tube.

    Drug: tissue plasminogen activator (tPA) and human recombinant deoxyribonuclease (DNase)

  • Active comparator
    Medical Thoracoscopy group

    Patients randomized to the Thoracoscopy group will undergo medical thoracoscopy.

    Procedure: Medical Thoracoscopy

Interventions

  • Drugtissue plasminogen activator (tPA) and human recombinant deoxyribonuclease (DNase)

    Patients will receive intrapleural combination of TPA (10 mg) and DNAse (5 mg). Therapy will be given twice daily for a maximum of 6 dose

  • ProcedureMedical Thoracoscopy

    Medical thoracoscopy will be performed as per standard protocols.

    Also known as: Pleuroscopy
