RETN and tuberculosis: Given the understanding that resistin is a proinflammatory molecule hence elevated among the TB patients[25, 26], we thereafter, compared the serum levels of resistin between non khat addicted TB patients and khat addicted TB patients to validate the above stated analogy, interestingly, that although the difference in serum resistin levels between the two group did not reach statistical significance (P>0.05) but relatively higher serum resistin levels were detected among the khat addicted tuberculosis patients “Fig 2”.
