Conclusion
INF-(is more sensitive and specific than ADA for the diagnosis of TB and should be added to the armamentarium of the diagnostic workup of pleural fluids for timely and accurate diagnosis of TB and differentiation of tubercular pleural effusion from non-tubercular effusion.
Results
Pleural fluids INF-γ, sIL-2R, TNF-α and ADA were significantly higher in TB group (n = 48) as compared to the non-TB group (n = 33) (mean ± SD: INF-γ; 1,958.7 ± 896.5 pg/mL vs 356.9 ± 733.6 pg/mL, sIL-2R; 6,101 ± 1,753.8 pg/mL vs 3,166 ± 2,611.1 ± pg/mL, TNF-α; 195.5 ± 292.1 pg/mL vs 59.7 ± 128.9 pg/mL, ADA; 123.6 ± 81.8 IU/L vs 48 ± 48.5 IU/L, P < 0.01).
