Abstract:
UNLABELLED:Pharmacokinetic (PK) parameters like C2h have improved efficacy of immunosuppressive therapy. However, drug interactions, toxicities, and individual differences to drug effects still remain challenging. Therefore, this study was designed to assess pharmacodynamic (PD) effects of the combination cyclosporin (CsA) plus mycophenolate mofetil (MMF) on lymphocyte functions in peripheral blood of stable heart transplant recipients (HTx) using our established FACS assays. METHODS:Blood from 25 HTx patients was drawn before (C0h) and 2 hours after dosing (C2h). CsA and mycophenolic acid (MPA) concentrations were measured by EMIT. FACS assessed expression of cytokine production (IL-2, TNF-alpha), lymphocyte proliferation (PCNA), and T-cell activation (CD25, CD95). RESULTS:Evening doses of CsA (25/50/75 or 100 mg) and MMF (250/500 or 1000 mg) produced C0h levels as follows: CsA, 162 +/- 12 ng/mL; MPA, 1.7 +/- 0.2 mg/L. Morning doses of CsA (50/75 or 100 mg) and MMF (250/500/1000 or 1500 mg) produced C2h-levels as follows: CsA, 589 +/- 56 ng/mL and MPA, 7.4 +/- 1.3 mg/L. PD effects at C0h/C2h (% expression +/- SEM, all P < .05) were IL-2, 18 +/- 3/10 +/- 2; TNF-alpha, 12 +/- 2/7 +/- 1; PCNA, 8 +/- 1/5 +/- 1; CD25, 26 +/- 4/13 +/- 2; CD95, 23 +/- 4/11 +/- 2). Correlations (r2) at time point C2h between inhibition of lymphocyte functions (PD) with drug concentrations (PK) and with drug doses were CsA-PK, 0.71 to 0.91; MMF-PK, 0.55 to 0.76; CsA-dose, 0.73 to 0.87; MMF-dose, 0.61 to 0.80. CONCLUSION:For the first time, the immunosuppressive effects of the combination CsA plus MMF were quantified in whole blood of human HTx at different time points. PD assays may offer the opportunity to optimize clinical immunosuppressive drug therapy.
