NOX1 Promotes Mesothelial-Mesenchymal Transition through Modulation of Reactive Oxygen Species-mediated Signaling.

Am J Respir Cell Mol Biol 2021 04;64(4):492-503

Department of Cellular and Molecular Biology, The University of Texas Health Science Center at Tyler, Tyler, Texas.

Pleural organization may occur after empyema or complicated parapneumonic effusion and can result in restrictive lung disease with pleural fibrosis (PF). Pleural mesothelial cells (PMCs) may contribute to PF through acquisition of a profibrotic phenotype, mesothelial-mesenchymal transition (MesoMT), which is characterized by increased expression of α-SMA (α-smooth muscle actin) and other myofibroblast markers. Although MesoMT has been implicated in the pathogenesis of PF, the role of the reactive oxygen species and the NOX (nicotinamide adenine dinucleotide phosphate oxidase) family in pleural remodeling remains unclear.

Intrapleural Fibrinolytic Therapy in Loculated Pleural Effusions.

M S Barthwal

J Assoc Physicians India 2020 Jun;68(6):32-34

Professor and Head, Department of Pulmonary Medicine, Dr D Y Patil Medical College, Hospital and Research Centre, Pimpri, Pune, Maharashtra.

About 36% to 57% of bacterial pneumonias develop parapneumonic effusion. When the chest tube is correctly positioned as evidenced by postero-anterior and lateral chest radiographs and there is a significant amount of pleural fluid, the major reasons for failed drainage are multiple pleural space loculations or tube obstruction by thick and viscous fluid. The various modalities of treatment available for loculated pleural effusion are: saline flushes, placing one or more catheters in loculi under image guidance, video assisted thoracoscopic surgery (VATS), standard thoracotomy with drainage of empyema and decortication.
