Tuberculosis Drug Levels in Diabetics

This study compares blood levels of tuberculosis medications between diabetic patients and non-diabetic patients. There is some research that suggests these medications are at lower levels in diabetic patients with tuberculosis, and this could adversely affect the outcome of their infection. Diabetic patients are at higher risk of dying or having a severe episode of tuberculosis therefore it is important that their care is optimised as far as possible. To answer the research question all participants in the study will have an extra blood sample drawn at the same time as their routine blood tests which are used to monitor their tuberculosis treatment. Some participants will have additional blood samples taken at different times to give a more accurate picture of the medication levels in their bloodstream. The study will be conducted in the tuberculosis clinics at London North West University Healthcare NHS Trust and will include adult patients with and without diabetes who have recently been diagnosed with tuberculosis. Some other information about their routine medications, weight and height, and severity of diabetes will also be collected, to see if these affect the medication levels in the bloodstream as well.
