Magister Pharmaceuticae - MPharm / The aim of the study was to determine firstly, kanamycin plasma concentrations using liquid chromatography coupled with mass spectrometry (LC/MS); secondly, to investigate the PK parameters of kanamycin in patients infected with MDR-TB and in patients co-infected with MDR-TB and HIV; thirdly, to assess the influence of HIV infection and renal impairment on the PK of kanamycin and fourthly, to find out whether there is any interaction between antiretroviral drugs and kanamycin.

Magister Pharmaceuticae - Mpharm / Many studies have investigated the pharmacokinetics (PK) of anti-tuberculosis drugs in tuberculosis patients. However, currently in South Africa, no studies have been done on ethionamide (ETH) PK in adult MDR-TB patients that are infected with HIV and those without HIV infection. Therefore, the objective of this current study was firstly, to find out ethionamide plasma concentration using the LC-MS method; secondly, to evaluate and compare the pharmacokinetics of ethionamide in MDR-TB patients infected with and without HIV infection; thirdly, to examine the effects of ARVs and kidney impairment on the PK of ethionamide and fourthly, to find out the consequence of sex and age on ETH PK parameters.
