Matrix metalloproteinases (MMPs) are proteins that play a role in the inflammatory and remodeling processes caused by infections, including pulmonary tuberculosis (TB), especially multidrug resistance. This study aims to investigate the relationship between variations in MMP-1 and MMP-9 blood levels, cavity features such as number, diameter, and wall thickness, and the location of fibrosis in multidrug-resistant (MDR) and drug-sensitive (DS) tuberculosis patients. This study used a comparative cross-sectional study design. The subjects, who were outpatients at Abdoel Moelok Hospital, Lampung, Indonesia, had passed the ethical test. We divided the subjects into two groups: 34 in the MDR-TB group and 36 in the DS-TB group. An ELISA test determined the levels of MMP-1 and MMP-9, while the PCR-sequencing method determined the genotypes of MMP-1 and MMP-9. Additionally, we measured cavities and fibrosis using thoracic high-resolution computerized tomography (HRCT) imaging. In MDR-TB patients, there was a significant difference in the number of cavities larger than 6.6 mm in diameter, as well as cavity thickness, compared to DS-TB patients. The distribution of fibrosis in lung segments was also significantly different in MDR-TB compared to DS-TB. Although MMP-9 levels in the MDR-TB group were higher than in the DS-TB group, there was no statistically significant difference. Based on HRCT measurements, this study found a link between MDR-TB and DS-TB in terms of the number of cavities, the diameter of the cavities, the thickness of the cavity walls, and the location of fibrosis in the affected lung segments. There was no link between the MMP-1 (−1607G) and MMP-9 (C1562T) genotypes and the levels of MMP-1 and MMP-9 in the blood. The MMP-1 genotype in the two study groups was very different and was linked to twice as many cases of MDR-TB. In addition, there was a substantial difference in cavity wall thickness between the G/G MMP-1 1607 genotype and the T/T MMP-9 genotype in the two study groups.
