Abstract

Sampling for urinalysis to see the activity and the degree of recurrence of Lupus Nephritis (LN) is very difficult. New biomarkersthat are more simple, sensitive, specific and non-invasive in assessing the activity of the LN need to be investigated. Interleukin-4 (IL-4)and interferon gamma (IFN-γ) were implicated to LN process. Urine samples from 17 LN patients were taken every month for 6 (six)months to examine the level of uIL-4, uIFN-γ, activity and recurrence of LN. Significant differences were observed in the uIFN-γ levelsbetween the active and inactive LN groups (p=0.012), but not in uIL-4 levels (p=0.187). Correlations between each biomarker andrenal domain score were weak (r=0.201, p=0.042 for uIL-4; r=0.268, p=0.006 for uIFN-γ). Significant differences were also found inthe uIL-4 and uIFN-γ levels against LN recurrence (p=0.033; p=0.017). The best cut off values to assess recurrences and activity of LNwere 8.17 pg/mL for uIL-4 showed a sensitivity of 74%, specificity 71%, NPV 90%, PPV 42% to assess recurrences and to assess activityof LN showed sensitivity 46%, specificity 75%, NPV 48%, PPV 78%. The cut off 18.58 pg/mL for uIFN-γ to predict recurrent and assessthe activity of LN showed sensitivity 68%%, specificity 70%, NPV 88%, PPV 40% to predict the recurrent and to assess the activity of LNshowed sensitivity 57%, specificity 64%, NPV 49%, PPV 73%. Based on the research, uIL-4 and uIFN-γ are not good enough to predictrecurrence and activity of LN

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.
