Pleural disease and acquired immune deficiency syndrome

Patients with acquired immune deficiency syndrome (AIDS) do not frequently have pleural complications. However, pneumothorax is a troublesome complication of patients with AIDS. At some medical centres, more than 50% of patients with spontaneous pneumothorax have AIDS. Most patients with spontaneous pneumothorax and AIDS have Pneumocystis carinii infection and necrotic subpleural blebs. The pneumothoraces in these patients usually cannot be managed with tube thoracostomy alone. Patients who do not respond to tube thoracostomy are best managed with a Heimlich valve or with thoracostomy with stapling of blebs and pleural abrasion. Approximately 2% of human immunodeficiency virus (HIV)-positive individuals will have a pleural effusion. Parapneumonic effusions or empyema, tuberculosis and Kaposi's sarcoma are the three leading causes. P. carinii infection is frequently responsible for pulmonary infections, but is only occasionally responsible for a pleural effusion. Pleural effusions may also develop from non-Hodgkin's lymphoma (NHL). There is one relatively rare NHL that is associated with the Kaposi's sarcoma associated virus that produces a lymphoma confined to the body cavity.
