RESULTS	All the inflammation markers significantly ( P < 0.05 ) decreased in the pentoxifylline group : TNF - [ baseline 0.4 ( 0-2 ) versus final 0 ( 0-0 ) pg/mL ] , IL-6 [ baseline 9.4 ( 5-14 ) versus final 2.9 ( 2-5 ) pg/mL ] and CRP [ baseline 7.1 ( 3-20 ) versus final 2.6 ( 1-8 ) mg/L ] , whereas no significant changes were observed in the placebo group : TNF - [ baseline 0 ( 0-0 ) versus final 1.2 ( 0-4 ) pg/mL ] , IL-6 [ baseline 8.0 ( 5-11 ) versus final 8.7 ( 4-11 ) pg/mL ] and CRP [ baseline 4.5 ( 2-9 ) versus final 3.8 ( 3-23 ) mg/L ] .\
