For instance, the reported frequency of indeterminate results is higher in septic patients [up to 29% (5)] than in healthy individuals [1.5% (9)]. Quantiferon TB minus NIL: result 0.40 H, ref ranges 0.00-0.35 IU/mL. Assessment of the accuracy of these tests is limited by lack of a standard for confirming LTBI. Proportion of patients with infectious complications during hospital stay after QFT sampling (A), intensive care unit (ICU) admissions (B), in-hospital mortality (C) and the median (interquartile range) hospital length of stay (D) were recorded and represented according to the mitogen response: negative (IFN- 0.5 IU/ml), weak (IFN- = 0.52 IU/ml) and normal (IFN- > 2 IU/ml). Asked by: Category: Infectious Disease Specialist. Immunocompromised status can result in indeterminate QuantiFERON-TB Gold In-Tube (QFT-GIT) results, but the association of indeterminate results with immunocompetent status in children is unknown. Second, patients with a weak mitogen response and negative mitogen response had several similarities. Inverse correlation between INF- mitogen, Inverse correlation between INF- mitogen response and C-reactive protein levels in hospitalized patients., Clinical outcomes of 872 hospitalized patients according to the mitogen response of QFT, MeSH This test is an in vitro diagnostic aid that measures a component of cell-mediated immune reactivity to M. tuberculosis. 13.

When p-value was <0.05, post-hoc 2 2 comparisons were performed using the Students t-test, Wilcoxon MannWhitney test and Chi-square test (or Fishers exact test), as appropriate. The Mitogen minus Nil value serves as the positive control, demonstrating the successful responsiveness of the T lymphocytes in patient specimen. Study protocol and data collection were registered with the CNIL (Commission nationale de linformatique et des liberts) and are in accordance with French (Loi Informatique et Libert n7817 du 6 janvier 1978) and European (GRPD EU 2016/679) regulations on data protection and patient information (Commitment of compliance MR004 n2210228 of 3 December 2018) with a waiver of informed consent given the non-interventional study design. Among tuberculosis patients, a weak mitogen response was associated with a false-negative QFT result (75%) compared to a normal response (20%). Copyright 2022 Jacquier, Binquet, Manoha, Audia, Simonet-Lamm, Casenaz, Sow, Piroth and Blot. Retrospective, case-control study in hospitalized patients who underwent QFT testing in two hospitals between 2016 and 2019. In the case of serially screened North American healthcare workers, QFT results just above this cutpoint produce false-positive test results that upon repeat testing revert to negative,[10] where tuberculosis screening is often mandated on an annual basis. The negative and weak mitogen response groups were younger (p < 0.001 for both) than normal response group and less frequently immunocompromised (p < 0.001 for both).

The TB antigen and mitogen results of the QFT-GIT test and lymphocyte counts for the cases sub-divided into different co-morbid conditions are illustrated in Table 4. The first test at the time of TB diagnosis (pulmonary and peritoneal involvement) was considered negative (Ag TB-Nil [IFN-] = 0.05 IU/mL), while the mitogen response was weak (mitogen [IFN-] = 1.03 IU/mL). All authors contributed to the article and approved the submitted version. QFT results indicative of M. tuberculosis infection include the following three criteria: (mitogen -- nil) and (tuberculin -- nil) are both >1.5 IU; and A total of 872 patients were included. (2021) 22:2-6. LabReqs. Patients under the age of 18, patients only admitted for consultation (as outpatients), those hospitalized for less than 48 h, and those with incomplete QFT results were not included (Figure 1). The gray section represents the IFN- values ranging in 0.2-0.7 IU/mL the so called "uncertainty zone". One quarter of the world population is potentially affected by a latent tuberculosis infection (LTI) (1). Cases were defined as patients with a negative mitogen response, (IFN- 0.5 IU/ml), as defined by the commercial supplier, or with a weak mitogen response (IFN- = 0.52 IU/ml). 0000015486 00000 n
The FDA's cutpoint for a positive result was established at >0.34 International Units/millilitre (IU/ml), though this has proven functionally problematic in low prevalence areas, such as among US and Canadian healthcare workers. Quantiferon TB minus NIL: result 0.40 H, ref ranges 0.00-0.35 IU/mL. The mitogen tube must demonstrate an interferon- value of equal to or greater than 0.5 IU/ml higher than the value of the NIL tube. 71775-1. Order LOINC Value. If QFT is performed, the mitogen response may serve as a surrogate biomarker for assessment of immune competence in hospitalized patients whose determinants are varied (old age, immunodepression, previous or current infection, which were associated with negative or weak mitogen response in our study).

MJ, MB, A-KS, CB, and LP: acquisition, analysis, or interpretation of data. Seeing that such a result is not a normal response to PHA stimulation, it may be thought to be a false negative QFT when diagnosing LTI, or even TB. Among tuberculosis patients, a weak mitogen response was associated with a false-negative QFT result (75%) compared to a normal response (20%). A M. bovis BCG a teszttel nem interferl. (2010) 35:1179-82. Fourth, the mitogen response was associated with hospital length of stay and in-hospital mortality. Front Immunol. Notice of Privacy Practices - Our results raise the question of whether a LTI can be confidently interpreted with a weak mitogen response. Acute infections observed at the time of QFT sampling were mainly bacterial (85%) and of pulmonary origin (56%) (Supplementary Table 1). In conclusion, it appears to be of utmost interest to consider the mitogen response in hospitalized patients who undergo QFT, in particular when this response is negative or weak (IFN- 2 IU/mL). Pourakbari B, Mamishi S, Benvari S, Mahmoudi S. Adv Med Sci. Shock. Infections are the most common cause of lymphopenia in hospitalized patients (10), and functional alterations have been observed in lymphocytes during infections such as sepsis/septic shock (11) and pneumonia (12, 13).

Detection of interferon-y by enzyme-linked immunosorbent assay (elisa) is used to identify in vitro responses to these peptide antigens that are associated with mycobacterium tuberculosis infection. Trained immunity, tolerance, priming and differentiation: distinct immunological processes. The negative correlation we observed between C-reactive protein and mitogen response further supports this assumption. Correlation between INF- mitogen response of QFT and C-reactive protein levels was assessed in hospitalized patients included in the study and with available C-reactive protein data (, Clinical outcomes of 872 hospitalized patients according to the mitogen response of QFT (negative, weak or normal). previously reported that a lower mitogen response was associated with worse 1-year survival in TB patients (27). The QuantiFERON TB Gold test does not distinguish between these two, but they differ based on how they manifest in an infected person. The result of the test is a numeric value that relates to a continuous numeric scale.

Lee JY, Choi HJ, Park I-N, Hong S-B, Oh Y-M, Lim C-M, et al. In addition, the clinical relevance of the standard 0.5 IU/mL threshold is a matter of debate, and it has been suggested that a response to PHA with IFN- < 10 IU/mL could be considered possibly altered rather than normal (18). We recognize that technique may not be the only factor and we accept that mitogen values are currently not in a range that customers have previously observed. The QuantiFERON-TB Gold test (QFT-G) is a whole-blood test for use as an aid in diagnosing Mycobacterium tuberculosis infection, including latent tuberculosis infection (LTBI) and tuberculosis (TB) disease. The presence of an active infection within the last 3 months or at the time of the QFT sampling were recorded if the infection was clinically/biologically suspected or confirmed by the clinician in charge of the patient.
