    Abstract: BACKGROUND: BCG vaccine has been proven to be effective protection against tuberculosis (TB) meningitis and miliary TB. However, for protection against pulmonary TB, the results remains vary widely. Recombinant vaccine consisting of two immunodominant Mtb antigens ESAT-6-Ag85C-polyHistag (EAH) is currently being developed as a new TB vaccine candidate for booster. An immugonecity test for vaccine candidates is required in the initial phase to evaluate cellular immune response. This study was conducted to evaluate the cellular immune response by measuring interferon-gamma (IFN-γ) cytokines produced by T cells after ex vivo stimulation by TB EAH antigen fusion.METHODS: Peripheral blood mononuclear cells supernatant samples were collected from 16 new pulmonary TB subjects, 17 pulmonary TB in treatment subjects, and 10 healthy subjects. Samples were tested for IFN-γ level with enzyme-linked immunosorbent assay (ELISA). Kruskal-Wallis test was used to test the differences between IFN-γ levels among three groups, and followed by post-hoc analysis using Mann Whitney.RESULTS: The median of IFN-γ levels for new pulmonary TB, pulmonary TB in treatment, and healthy subjects were 17.09 (2.65-140.14) pg/mL, 4.36 (2.43-21.41) pg/mL, and 2.91 (2.39-3.85) pg/mL, respectively. There were significant differences of IFN-γ levels between new pulmonary TB group and pulmonary TB in treatment group (p=0.012), between new pulmonary TB group and healthy group (p=0.001), and also between pulmonary TB in treatment group and healthy group (p=0.035).CONCLUSION: Results show that TB EAH could stimulate cell-mediated immune responses in the three groups, with the highest IFN-γ levels are found in new pulmonary TB group, suggesting a potential immunodominant antigen fusion for vaccine candidate development.KEYWORDS: Ag85C, ESAT-6, immunogenicity test, IFN-γ, TB vaccine candidate, tuberculosis

    Abstract: BACKGROUND: Currently, laboratory diagnosis of intestinal tuberculosis (ITB) is limited based on clinical manifestations, providing opportunities for alternative laboratory tests to diagnose ITB. At the present time, the role of serum adenosine deaminase (ADA) and hematological tests in ITB patients are not widely known. The objective of this study was to determine the role of ADA and hematological tests in patients suspected with ITB.METHODS: Subjects that were suspected of ITB were classified as ITB group, while subjects with inflammatory bowel disease, hemorrhoid, and intestinal malignancy were classified as non-ITB group. Colonoscopy, histopathological examinations, and hematological test were performed. ADA measurement was also performed with clinical chemistry analyzer based on enzymatic colorimetry principle.RESULTS: Out of 143 subjects, 16 (11.2%) subjects were diagnosed with ITB and 127 (88.8%) subjects were classified as non-ITB group. ADA level and erythrocyte sedimentation rate (ESR) of ITB group were significantly higher than the ones of non-ITB group (p 〈 0.05). Cut-off, sensitivity, and specificity of ADA level were 12.56 IU/L, 75%, and 57%, respectively. Cut-off, sensitivity, and specificity of ESR were 32.5 mm/hour, 81%, and 62%, respectively. Colonoscopy of ITB subjects displayed multiple ulcerations, edema, and hyperemic mucosa. Histopathological examination of ITB subjects exhibited granulomatous inflammation, epitheloid cells, giant cells, and lymphocyte aggregates.CONCLUSION: ADA level and ESR were significantly higher among ITB patients compared with non-ITB patients. Since the sensitivities of ADA and ESR tests were high, the ADA and ESR tests could be considered as a screening test for ITB.KEYWORDS: intestinal tuberculosis, adenosine deaminase, hematological tests

    Abstract: BACKGROUND: Tuberculosis (TB) infection is one of the most prominent health issues in the world, including in Indonesia. TB is evolving into multidrug-resistant tuberculosis (MDR-TB) and requiring second-line TB drugs. Mycobacterium growth indicator tube (MGIT) is the gold standard for susceptibility testing of second-line TB drugs. Alternatively, line probe assay (LPA), which detects genes resistant to second-line TB drugs, takes a shorter time to run. This study aims to compare MGIT and LPA's ability to detect TB resistance to second-line TB drugs and observe mutation patterns of genes encoding second-line TB drugs.METHODS: This was an observational analytic study, using cross-sectional method. The data were acquired from the MDR-TB clinic’s medical records at the Dr. Hasan Sadikin Hospital from September to December 2019. LPA and MGIT test were conducted at the Health Laboratory Hall of West Java Province, then tested using Kolmogorov-Smirnov and chi-square statistic.RESULTS: From 121 subjects, 113 people were not resistant to the second-line TB drugs, which was examined using both LPA and MGIT (93.4%), p=0.991. Mutations were found in gyrA and rrs gene. There was no significant difference between the proportion of subjects resistant to the second-line of TB drugs tested using LPA and MGIT.CONCLUSION: LPA is an alternative method to MGIT because it requires a shorter time and reduces the risk of exposure that will improve MDR-TB patients management.KEYWORDS: line probe assay (LPA), multidrug-resistant TB, mycobacterium growth indicator tube (MGIT), second-line TB drugs
