Background: Among the factors involved in degradation and remodeling of lung tissue as part of tuberculosis infection include MMPs, MDPs and TIMPs. Likewise, it is known that hyperglycemia leads to an increased risk of failure of TB treatment. Hyperglycemia could indirectly mediate the expression of these biomarkers by increasing oxidative stress, which can be quantified by HO-1 activity. Material and Methods: Descriptive pilot study. The concentration of biomarkers in bronchoalveolar lavage fluid (BALF) samples was evaluated using ELISAs and Luminex©. Univariate analysis was performed using SPSS Statistics-26® Objective: Compare the levels of MMPs, MDPs, TIMPs and HO-1 in BALF of TB patients with hyperglycemia and TB patients with normoglycemia and evaluate the association between hyperglycemia and oxidative stress with these variables. Results: TB-Hyperglycemia group presented more pulmonary caverns compared to TB-Normoglycemia group(p=0.248). The mean concentration of MMP-1 (85.5 pg/ml) and PIIIN (4.5 ng/ml) was higher in TB-Hyperglycemia group (p=0.715 and 0.114, respectively). In the hierarchical cluster analysis, the only group that manages to form a cluster is TB-Hyperglycemia. Finally, TB-Hyperglycemia and TB-Normoglycemia groups presented more correlations between the studied biomarkers (p<0.05). Conclusions: There is an elevation of inflammatory biomarkers such as MMPs, MDPs, TIMP and HO-1 in BALF samples, and this expression profile is associated with their diagnostic status of TB and their glycemic status.
