CRP and tuberculosis: The MDR-TB patients had significantly lower CRP values (MDR-TB median 11 mg/L, control group median 32 mg/L, p = 0.03), significantly higher lymphocyte counts (MDR-TB mean 1.8×109/L, control group mean 1.5×109/L, p = 0.04), and significantly more MDR-TB patients had normal vitamin D levels (MDR-TB 54%, control group 12%, p = 0.007) (data not shown), although none of these factors could be used to distinguish MDR-TB from a fully sensitive case.
