The change in blood glucose levels in tuberculosis patients before and during anti-tuberculosis treatment in China.

Objective: We aimed to observe (i) changes in fasting blood glucose (FBG) in tuberculosis (TB) patients before and during anti-TB treatment, (ii) whether FBG levels were stable or unstable and (iii) baseline characteristics associated with an unstable FBG.

Method: TB patients consecutively attended six clinics or hospitals. FBG measurements were made at months 0, 2 and 6.
