Backgroundː whereas that systemic inflammation (SI) affects 40–60% of patients on hemodialysis (HD) is characterized by serum C-reactive protein (CRP) level elevation or proinflammatory interleukin production or both. We evaluated the association between SI and total (tPSA) and free PSA (fPSA) in patients on HD with tPSA <4ng / ml. Methodsː Sixty patients with chronic kidney disease (CKD) undergoing HD and 20 controls were included. Inclusion criteria were patients aged 18-60 years; tPSA < 4

... mL without clinically detectable prostate cancer; and patients undergoing HD for >6 months. Patients were excluded if they had local infections or SI. Hs-CRP was measured using turbidimetry, and tPSA and fPSA levels using immunochemoluminescence. Overall, 27 patients had inflammation (hs-CRP >5 mg/L) and 33 had no inflammation (hs-CRP was ≤5 mg/L). In the control group, hs-CRP was ≤ 1 mg/L. Resultsː there was no significant difference in mean levels among groups 3 and 4 for age (p=0,058), tPSA (p=0,74) and fPSA (p=0,30). The SI did not promote differences between groups 1, 2 and 4 for the levels of tPSA (0,71 ± 0,18 vs 0,67 ± 0,15 vs 0,67 ± 0,11; p=0,69) and fPSA (0,34 ± 0,01 vs 0,34 ± 0,01 vs 0,35 ± 0,01, p= 0,59) . As well as maintained no correlation with tPSA and fPSA (p>0,05). Conclusionː The systemic inflammation in hemodialytic patients without clinically detectable cancer (PSA<4ng/ml) is no associated with changes fractions of tPSA and fPSA.
