Such observations suggest that ongoing infection could be a frequent cause of negative mitogen response. QuantiFERON-TB Gold (QFT) is a simple blood test that aids in the detection of Myc Among tuberculosis patients, a weak mitogen response was associated with a false-negative QFT result (75%) compared to a normal response (20%). 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).

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). Data were collected from the 3 groups of patients constituted, namely the cases (all the patients with a negative or a weak mitogen response) and the control patients (1 control patient/case with a normal mitogen response). xref

Continuous variables were expressed as means standard deviation (SD) or medians and inter-quartile range (IQR), according to distribution, and categorical variables were expressed as frequencies and percentages. In the example cited above, the nil value (0.07 IU/mL) is well within the recommended range of 8.0 IU/mL. 3. 2022 Oct 26;9:1027708. doi: 10.3389/fmed.2022.1027708.

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. The California Tuberculosis Controllers Association have also provided a list of public health laboratories[23] in California that are testing with Quantiferon. 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 Crit Care. When the variable a severe infection at the time of the QFT was added in the model instead of an ongoing infection at the time of QFT (model 4), this first was independently associated with a negative mitogen response (RR = 2.78; 95% CI [1.037.51]) (Supplementary Table 4 and Supplementary Figure 3). 71775-1.

QuantiFERON-Tb Gold Plus, B. 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). All variables associated with IFN- production with a p-value < 0.2 and at least 15 observations in each group were accounted for. We defined two groups of cases with either negative [interferon (IFN)- 0.5 IU/ml, official threshold] or weak (0.52 IU/ml) mitogen response, and one group of controls with normal (>2 IU/ml) mitogen response. (2020) 11:1364. doi: 10.3389/fimmu.2020.01364. 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. In addition, the contribution of the two tubes TB1 and TB2, evaluating, respectively, the T-CD4 and T-CD8 responses, did not allow to mitigate this limitation since both T-CD4 and CD8 are non-selectively affected by T-cell exhaustion during sepsis (23). 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). Mitogen or Positive Control Tube A test is considered positive for an IFN- response to the TB Antigen tube that is significantly above the Nil IFN- IU/mL value. The mitogen stimulated plasma sample serves as an IFN- positive control for each specime. All authors contributed to the article and approved the submitted version. [12][13], Limitations of QFT include the need to draw blood and process it within 16 hours after collection and limited laboratory and clinical experience with the assay. 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. -. MJ, MB, CB, and LP: concept and design.

Septic shock as sepsis with persisting hypotension requiring vasopressors to maintain mean arterial pressure 65 mm Hg and had a serum lactate level >2 mmol/L (18 mg/dL) despite adequate volume resuscitation (19). According to the U.S. Centers for Disease Control,[2] in 2001, the QuantiFERON-TB test (QFT) was approved by the Food and Drug Administration (FDA) as an aid for detecting latent Mycobacterium tuberculosis infection. (2009) 33:812-5. doi: 10.1183/09031936.00075008, 8. This TB blood test is highly accurate, with sensitivity of 94% and specificity of 97%.

These results offer new insight about QFT performance, particularly during TB, which is associated with both systemic inflammation and T-cell exhaustion.

Because IGRAs are not affected by Bacille CalmetteGurin (BCG) vaccination status, IGRAs are useful for evaluation of LTBI in BCG-vaccinated individuals, particularly in settings where BCG vaccination is administered after infancy or multiple (booster) BCG vaccinations are given. Third, among confirmed TB patients, a weak mitogen response was associated with false negative QFT results. (2014) 42:383-91. doi: 10.1097/SHK.0000000000000234, 11.

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). 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. and transmitted securely. [8] In a more recent study of military returning from missions, Franken et al. A mitogen is a small bioactive protein or peptide that induces a cell to begin cell division, or enhances the rate of division (). This may occur due to a low lymphocyte count, reduced lymphocyte activity, or inability of the patient's lymphocytes to generate IFN-gamma. The Supplementary Material for this article can be found online at: https://www.frontiersin.org/articles/10.3389/fmed.2022.876864/full#supplementary-material.

The exhaustion of T lymphocytes is a well-known consequence of sepsis (23) and other chronic infections such as TB (17, 24), minimizing the damage to host tissue related to inflammatory response (25). (2018) 31:e2118. Of the 75 indeterminate test results, 73 (97.33%) were due to low mitogen (i.e., Phytohaemagglutinin) response, with IFN- less than 0.5 IU mL -1.

The mitogen threshold of 2 IU/mL was arbitrary defined to obtain balanced groups between negative and weak mitogen response groups. First, the presence of an ongoing infection at the time of QFT was independently associated with a negative mitogen response and therefore indeterminate QFT results. Am J Respir Crit Care Med.
