Cyclosporine A (CsA) is the first calcineurin inhibitor used as immunosuppressive agent. Its administration is associated with multiple adverse effects including cardiovascular diseases (CVDs), but their mechanisms have not been fully elucidated. Cyclosporine metabolites are not well studied in this context. This study was aimed at analysis of the incidence of CVDs and their association with concentrations of cyclosporine and its metabolites. Sixty patients after kidney transplantation (KTX) taking an immunosuppressive regimen including CsA participated in the study. There were 22 women (36.67%) and 38 men (63.33%), mean age 51.73 years, mean 109.38 months after KTX. We observed a correlation between mean diastolic blood pressure and concentrations of metabolite to parent drug ratios of AM1-CsA/CsA (r = 0.35, P = .006), dihydroxy-CsA/CsA (r = 0.42, P = .001), trihydroxy-CsA/CsA (r = 0.42; P = .003) and desmethyl-carboxy-CsA/CsA (r = 0.65, P = .003). There were no significant associations of other CsA metabolites' parameters with CVDs (coronary disease, hypertension, stroke, arrhythmia, diabetes mellitus, obesity). Study results suggest that blood pressure increases associated with CsA therapy could be caused by CsA metabolites that influence mainly diastolic blood pressure levels. A lack of such differences in relation with other CVDs may suggest that more complex mechanisms are involved in the development of cardiovascular injury and disease after kidney transplantation.
