Abstract

Tuberculosis (TB) is caused by Mycobacterium tuberculosis (M.tb) and is one of the significant mortality causes WHO (2012). Theprimary immune response in TB pathogenesis is Cell Mediated Immunity (CMI), roled by T lymphocytes. Interleukin-2 (IL-2) is a growthfactor for T lymphocytes. Gamma Interferon is the key cytokine in M.tb infection control, synthezised by T lymphocytes. An effectivevaccination strategy is achieved by giving vaccine which is able to stimulate T lymphocytes in synthezising cytokines. The 38 kDa M.tbprotein is potential in the vaccine development program, because it has specific epitopes for T lymphocytes. The aim of this study was toknow how to determine that the 38 kDa recombinant protein of M.tb Malang strain could induce cellular immune response by IL-2 andIFN-γ synthezised by T lymphocytes. The study was carried out by an experimental in vitro study on PBMC from healthy endemic subjects,those having TB contact, and the TB patients themselves. PBMC from subjects was cultured with 38 kDa recombinant protein of M.tbMalang strain, with PPD and without any protein. The analysis of IL-2 and IFN-γ used flowcytometry. The result showed that the highestpercentage of IL-2 was found in the culture with 38 kDa recombinant protein of M.tb Malang strain, in healthy endemic (p=0.000)and in those who had TB contact (p=0.000). the highest percentage of IFN-γ was found in the culture with 38 kDa recombinant proteinof M.tb Malang strain, in healthy endemic (p=0.007) and those who had TB contact (p = 0.105). The 38 kDa recombinant proteinof M.tb Malang strain was able to induce IL-2 and IFN-γ synthezised by TCD3+ lymphocytes from healthy endemic subjects and thosewho had TB contact.

Abstract

Background: Toxic particles within tobacco smoke are responsible for several respiratory system problems. Among these toxic particles is Carbon Monoxide (CO), produced from environment and Heme Oxygenase induction. Expiratory CO levels can be measured using CO analyzer. CC16 is a pneumoprotein produced by club cells in distal respiratory tract. In acute condition, CC16 level will increase to maintain homeostasis and anti-inflammation. In chronic condition, i.e. in smokers, CC16 will decrease, following destruction of Club cell. This study aims to determine exhaled CO (eCO) levels and serum CC16 levels in active smokers. Methods: This cross-sectional analytical study design has 40 samples of healthy smokers in Brawijaya University who consents to the research from October 2019 until June 2020. The minimum consumption amount is 1 cigarette per day for at least 1 year. eCO levels are measured using CO analyzer (Smokelyzer), while ELISA is used to measure serum CC16 levels. Results: Among 40 subjects, mean eCO level is 10.18 ± 7.42 ppm. Mean serum CC16 level is 3.17 ± 1.78 ng/mL, lower than normal value of 6.4 ng/mL (Lomas et al., 2008). Conclusion: eCO levels increases and serum CC16 level decreases in active smokers, who smokes at least 1 cigarette/day for at least 1 year. This indicates that CO from tobacco smoke could irritate and damage the Club cells in the respiratory system.
