What are the differentially expressed proteins in tuberculous pericardial effusion compared to heart failure-related effusion?
Proteomic analysis identified 11 differentially expressed proteins in tuberculous pericardial effusion, highlighting a potential role for fibrinogen in fibrin assembly.
Differential protein expression may distinguish tuberculous from heart failure pericardial effusions; leaves open clinical adoption pending prospective validation.
The aim of this study has been designed to identify the tuberculosis (TB)-related proteins in pericardial effusion by proteomic approaches. TB is one of the major infectious diseases causing pericardial effusion. This study details protein profiles in pericardial effusion from three TB patients and three heart failure patients. Pericardial effusions were analyzed using 2-DE combined with the nano-HPLC-ESI-MS/MS. Eleven protein spots with differential expression in pericardial effusion were identified between the two groups of TB and heart failure patients (the control group). Seven protein spots were upregulated and four were downregulated. The composition of the pericardial effusion proteome may reflect the pathophysiological conditions affecting the progression of tuberculous pericarditis. The proteins in the tuberculous pericardial effusion with differential expression may serve as new and direct indicators of drug treatment. A possible conclusion is indicated that fibrinogen may play an important role for fibrin assembly in tuberculous pericardial effusion.
