“…Plasma concentrations of IL-6, IL-8, IL-10, MCP-1, and TNF-α were 1.5-to 2.5fold higher in patients with rheumatoid arthritis compared with healthy individuals while there were no differences in IFN-γ and IL-1β concentrations. 55 Patients with psoriasis have substantially lower inflammation than rheumatoid arthritis with mean IL-6 plasma concentration of 4.2 pg/mL. 56 Accordingly, the pharmacokinetics of a single dose of venlafaxine (CYP2D6 and CYP3A4 substrate) is not different in patients with psoriasis (n = 13) compared with healthy individuals (n = 11).…”

“…Comparing these values to those for IL-6 (mean E min (range) = 0.230 (0.0622 -0.529) and mean EC 50 (range) = 1251 (142 -4070) pg/mL) (Table4; Dickmannet al, 2011) suggests IFN-γ is not as potent a CYP1A2 suppressor as IL-6. It should be noted that the IFN-γ concentrations used in vitro are far in excess of physiological concentrations in healthy subjects (7.5 -21.2 pg/mL or 0.3 ± 0.1 U/mL) and those with RA (17.9 -32.6 pg/mL), acute respiratory infections (3.4 ± 1.3 U/mL)(Brockmeyer et al, 1992;Caris et al, 2020) or acute lymphoblastic leukemia following blinatumomab administration (peak ~ 440 pg/mL)(Xu et al, 2015). Suppression of CYPs by tumor necrosis factor (TNF)-α has been measured in vitro in 5 studies(Abdel-Razzak et al, 1993;Aitken and Morgan, 2007; Dallas et al, 2012, Mimura et al, 2015Klein et al, 2015) Abdel-Razzak et al (1993).…”

“…Overall, only two studies were retrieved (Table 1 of the ESM) [ 39 , 40 ], and both investigated the inhibitory effect that pro-inflammatory cytokines may have on the OAPT1B1-mediated transport of statins during chronic inflammatory conditions. The first was a case-control PK study that tested the potential influence of a chronic inflammation state on the PK behavior of fluvastatin by comparing the profile of this probe drug of the hepatic sinusoidal OATP1B1 activity between 15 patients with RA and ten healthy volunteers [ 39 ]. Patients with RA had significantly higher median IL-6 levels (11.2 pg/mL vs 4.94 pg/mL; p < 0.05) and TNF-α levels (39.9 pg/mL vs 21.1 pg/mL; p < 0.05) compared with healthy subjects.…”
