Safety of long-term lopinavir plasma-levels in patients with liver disease.
Chronic liver disease is often found in HIV infected patients. LPV as first choice drug is often used over long time periods. TDM as a tool in patients care is important but the knowledge of LPV-plasma-levels in patients with chronic liver disease remain uncertain. With this retrosepective analysis we want to show if there are differences in LPV-plasma-levels between patients with and without chronic liver diseases over a long-time period. LPV-plasma-levels were analysed with an HPLC-based methode. The LPV-plasma-levels over the time course in patients with chronic liver disease (n = 30) and patients without liver disease (n = 38) was evaluated. Liver function tests, CD4-cell count and HI-viral load was also correlated with liver disease. The LPV plasma-levels of n = 450 samples from 30 patients with liver disease (Hepatitis B: n = 17, Hepatitis C: n = 16, Alcoholic liver disease: n = 7) were determined over 18.7 +/- 16,3 months (1 - 48.5 months). A median of 10 samples per patient was eligible (2 - 50 samples). There are no significant differences according to liver disease in LPV-plasma levels (mean Ctrough without: 5917 +/- 4811 ng/ml, mean Ctrough with liver-disease: 6564 +/- 4517 ng/ml, p > 0.05). The intraindividual and interindividual variation of LPV-plasma levels, CD-4 increase, HI-virus suppression and liver tests in patients with and without liver disease is comparable. In this clinical setting no differences in LPV-plasma levels between patients with and without chronic liver disease could be demonstrated. LPV-therapy in patients with chronic liver disease is therefore safe. In patients with impaired liver function TDM is a helpful tool for dose adjustment.
