BACKGROUND: Pentoxifylline (PTF) is a potential therapeutic agent in chronic kidney disease due to its antiinflammatory and antiproteinuric effects that may influence the progression of renal disease. SUBJECTS AND METHODS: We conducted a prospective randomized trial of 91 patients with estimated glomerular filtration rate (eGFR) <60 ml/min, calculated with 4-variable Modification of Diet in Renal Disease (MDRD-4) Study equation. Patients were randomly assigned to treatment with PTF 400 mg (twice a day) (n=46) or to continue their usual therapy (n=45). Clinical, biochemical and inflammatory parameters were measured at baseline, and at 6 and 12 months of treatment. The objective of the study was to analyze the effect of PTF treatment on inflammatory markers and secondarily the effect on renal disease progression. RESULTS: Baseline characteristics were similar in the 2 groups. High-sensitivity C-reactive protein (hs-CRP), serum fibrinogen and TNF-alpha decreased significantly in patients treated with PTF in comparison with the control group at 12 months (p=0.002, p=0.001 and p=0.000, respectively). Median urinary albumin excretion did not decrease with PTF treatment. In the PTF group, there was no significant change in eGFR after 12 months (from 42.3 ± 10.2 to 44.7 ± 11.3 ml/min per 1.73 m(2)), whereas in the control group there was a worsening by the end of the study (from 40.1 ± 12.4 to 35.7 ± 13.4 ml/min per 1.73 m(2)) (p=0.000 between groups). CONCLUSIONS: PTF treatment decr...
