Abstract

The immune responses of multidrug-resistant tuberculosis (MDR-TB) patients undergoing lung resection surgery were investigated in order to understand the mechanism of strong immune suppression in MDR-TB. We examined changes in cell-mediated immune response (CMI) of a total of sixteen MDR-TB patients, three of them extensively drug-resistant tuberculosis (XDR-TB) patients, after the removal of the heavily diseased lung section. The IFN-γ response to Mycobacterium tuberculosis culture filtrate proteins (Mtb-CFP), one of the most important CMI to defend TB, showed a statistically significant elevation in 2-4 months after operation when compared to the preoperative CMI in patients who were converted into AFB negative and cured in two years' follow-up, suggesting that the recovery of CMI may be one of the key factors in the successful treatment of MDR-TB. Interestingly, IL-10 response to Mtb-CFP was also elevated in 2-4 months after surgery in cured patients although both proliferative response and PBMC composition were not significantly changed. Infection with first- or second-line drugs resistant Mtb reduces the efficiency of chemotherapeutic treatment of MDR-TB to about 50%. Thus, this study suggests that chemotherapeutic treatment of MDR-TB may be more effective when combined with accompanying therapy that increases CMI, includes lung resection surgery.
