Abstract

Background: The lifetime risk of TB reactivation develops within the first 5 years after initial infection. Good LTBI management helps in preventing the progression of the disease to be active. It is recommended in countries with a low prevalence of TB infection and high risk populations such as DM patients. The diagnosis of LTBI is done by examining TST and T-SPOT.TB. This study aimed to determine the correspondence between TST and T-SPOT.TB in detecting LTBI in DM patients. Methods: This cross-sectional study was conducted in DM patients treated in Dr. Moewardi Hospital Surakarta in September 2018. The study subjects received TST by injecting intradermal PPD RT 23 2TU intradermally, and T-SPOT.TB by taking 6 ml of venous blood examined with ELISPOT method. Statistical analysis used SPSS21 for windows. Results: There were 30 subjects. The prevalence of LTBI was 20%. The correspondence between TST and T-SPOT.TB was substantial (K=0.667, p

Abstract

Background: WHO identifies diabetes mellitus (DM) as a neglected risk factor for tuberculosis (TB). Currently, there is no gold standard test for latent TB infection (LTBI). Centers for Disease Control and Prevention (CDC) recommends using Tuberculin Skin Test (TST) and Immunoglobulin Gamma Release Assay (IGRA) to diagnose LTBI. TST is an LTBI classic diagnostic tool that has low sensitivity and specificity. But it is still preferred in diagnosing LTBI due to its lower price, and more health facilities can perform the examination compared to IGRA (T-SPOT.TB). The study aimed to measure the agreement of TST and T-SPOT.TB testing in detecting LBTI in DM and the correlation of HbA1c with TST and T-SPOT.TB.Subjects and Method: Subjects were DM patients who underwent TST and T-SPOT.TB testing. If the results of TST and T-SPOT.TB was positive, the test would be continued with Xpert MTB/RIF microbiological testing. TST used PPD RT23 2TU. T-SPOT.TB was performed toward peripheral blood mononuclear cells. The degree of agreement between TST and T-SPOT.TB testing was calculated using the Test of Agreement (Kappa Cohen). The degree of correlation between the two variables was calculated by using Pearson correlation.Results: The selected 30 study subjects with DM undergoing antidiabetic therapy showed 6 (20%) detected LTBI and 24 (80%) without LTBI using TST and T-SPOT.TB test. There was a substantial agreement level between TST and T-SPOT.TB testing in detecting LTBI among diabetes mellitus patients undergoing anti-diabetic therapy with kappa value= 0.62 (p<0.001). HbA1c increased T-SPOT (r= 0.07; p= 0.716) and TST (r= 0.11; p= 0.956).Conclusion: TST testing may substitute T-SPOT.TB to detect LTBI among diabetes patients undergoing antidiabetic therapy.Keywords: latent tuberculosis infection, diabetes mellitus, TST, Immunoglobulin Gamma Release Assay (IGRA), T-SPOT.TBCorrespondence: Reviono.
