QuantiFERON; infection; mitogen; mortality; outcomes. Interestingly, one patient underwent serial QFT. Third, the cutoff we used to define weak mitogen response is rather arbitrary, and whether higher thresholds would be associated with different parameters and outcomes was not assessed. 0000019861 00000 n Multivariable analyses identified age, immunodepression, serum albumin, hemoglobin, and neutrophil and lymphocyte counts as factors associated with a negative mitogen response, as previously reported (3, 7). Programmed death-1 levels correlate with increased mortality, nosocomial infection and immune dysfunctions in septic shock patients.

Although the numbers were small, all of the close contacts who went on to develop active TB were QFT positive, but only 83% were TST positive. [11] Research at Stanford University and the Veterans Administration has reported the use of a retesting (or borderline) zone below 1.1 IU/ml mitigates 76% of the false-positives, or reversions. Huang C-T, Lee M-R, Ruan S-Y, Tsai Y-J, Wang J-Y, Yu C-J. As with most medical processes, the QuantiFERON TB Gold test has its pros and cons. 0000002584 00000 n Specimen Requirements: . It decreased again in the U.S. in 1993 but is still a concern as tuberculosis cases can re-emerge. The mitogen response (respectively normal, weak and negative) was associated with an increasing proportion of patient with onset of infectious complications (2, 5, 12%; p < 0.001), ICU admissions (3, 15, 32%; p < 0.001), hospital length of stay [median (interquartile range) = 5 (313); 11 (521) and 15 (1030) days; p < 0.001] and in-hospital mortality (3%, 7% and 15%; p < 0.001) (Figure 2 and Supplementary Table 6). 0000024723 00000 n Comparison of two commercial interferon-gamma assays for diagnosing Mycobacterium tuberculosis infection. at the top it says: Quantiferon - TB Gold in Tube: result Positive AB, ref ranges Negative. As such, the CDC has advised that the QuantiFERON test be done either on the same day that the live vaccine is administered or a minimum of four weeks after. Table 1. 24. Before government site. Positive or Abnormal. This test was approved by the U.S. Food and Drug Administration (FDA) in 2005.

The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest. Conclusion: Primary site and microbial origin of the infection at the time of the QFT were also recorded. Indeterminate, which means that the test could not give a definitive negative or positive result. 4. -, Hradsky O, Ohem J, Zarubova K, Mitrova K, Durilova M, Kotalova R, et al. In each final model, interactions between selected variables were systematically tested. Table 2 . 10.1097/MPG.0000000000000205 It spreads from one person to another via tiny water droplets which are excreted into the air when an infected person coughs or sneezes. Mitogen-Nil The maximum non-specific stimulated interferon- gamma level that may be produced by the patient's lymphocytes minus the Nil (i.e., basal) level of interferon-gamma. All variables associated with IFN- production with a p-value < 0.2 and at least 15 observations in each group were accounted for. (2012) 6:419-24. (2012) 6:419-24. doi: 10.1016/j.crohns.2011.09.011, 6. The mechanism of action of a mitogen is that it triggers signal transduction pathways involving mitogen-activated protein kinase (MAPK), leading to mitosis. *Correspondence: Mathieu Blot, mathieu.blot@chu-dijon.fr, https://www.frontiersin.org/articles/10.3389/fmed.2022.876864/full#supplementary-material, Creative Commons Attribution License (CC BY). Outside the scope of TB, the weak mitogen response was independently associated with ongoing infections and could be associated with a worse prognosis. Belliere J, Blancher A. QuantiFERON test interpretation in patients receiving immunosuppressive agents: an alert. Range of Values: 1581: 1581. No use, distribution or reproduction is permitted which does not comply with these terms. QuantiFERON TB Gold test is a basic blood test that helps in the detection of the Mycobacterium tuberculosis which is responsible for causing tuberculosis. 0000002316 00000 n At the time of the QFT sampling, an ongoing infection was detected in, respectively, 18, 33, and 48% of patients with a normal, weak and a negative mitogen response, respectively, and septic shock was detected in 1, 4, and 11%, respectively. T-cell exhaustion in tuberculosis: pitfalls and prospects. Among tuberculosis patients, a weak mitogen response was associated with a false-negative QFT result (75%) compared to a normal response (20%). reduced by the IFN- concentration in nil tube. Khan N, Vidyarthi A, Amir M, Mushtaq K, Agrewala JN. Divangahi M, Aaby P, Khader SA, Barreiro LB, Bekkering S, Chavakis T, et al. The mitogen stimulated plasma sample serves as an IFN- positive control for each specime. mL1 [2]. Lange B, Vavra M, Kern WV, Wagner D. Indeterminate results of a tuberculosis-specific interferon- release assay in immunocompromised patients. Age and sex in the 436 included control patients did not differ significantly from the 1,587 patients who were not selected as controls (59 19 vs. 57 19 years; p = 0.06, and 50% female vs. 48%; p = 0.54). Clin Microbiol Rev. In addition, mitogen response was inversely correlated with C-reactive protein concentrations (Figure 1).

Log-linearity was tested for each continuous variable using fractional polynomials (20). Asked by: Category: Infectious Disease Specialist. If the patient is infected with M. tuberculosis, their white blood cells will release IFN-gamma in response to contact with the TB antigens. NIL 0.07 IU/mL KS MITOGEN-NIL >10.00 IU/mL KS TB-NIL 0.00 IU/mL KS The Nil tube value is used to determine if the patient has a preexisting immune response which could cause a Knock out the normal WRNMMC - screen new hires, varies between Two Step Testing and IGRA . Blot M, Zeggay A, Aho-Glele LS, Laborde C, Le Moing V, Chirouze C, et al. This manifests through attenuated cell proliferation, impaired cytotoxic function, and attenuated IL-2 and IFN- production (23). 0000016156 00000 n Name Value Reference Range NIL 0.040 UI/mL MITOGEN-NIL 10.065 IU/mL TB Ag-NIL 0.479 IU/mL INTERFERON GAMMA RESULTS POSITIVE NEGATIVE. The negative and weak mitogen response groups were not significantly different for these two variables. Lee JY, Choi HJ, Park I-N, Hong S-B, Oh Y-M, Lim C-M, et al. To better evaluate the IFN responses to mitogen stimulation, we performed the analysis using the values without transforming the IFN values > 10 IU/mL in values = 10 (B) and the values converted in 10 IU/mL (C). Blood samples must be processed within 16 hours after collection while white blood cells are still viable. In case of both immunodepression and diabetes, the effect of these both variables was lowered (p for interaction = 0.011 when comparing negative vs. normal mitogen response groups). May also include abnormal ranges. Fourth, the mitogen response was associated with hospital length of stay and in-hospital mortality. (2014) 189:77-87. doi: 10.1164/rccm.201302-0365OC, 10.
