(2010) 35:1179-82. A confirmatory test based on QuantiFERON technology was developed in which mitogen tubes were filled with 1 mL of whole blood from a healthy donor to which 100 L (1:10 dilution) or 20 L (1:50 dilution) of NTM patient serum . 0000001772 00000 n Annu Rev Physiol. 0000001563 00000 n QuantiFERON-TB Gold PLUS (4 tube assay). At your doctor's appointment, you will discuss your risk of developing the TB disease and also the treatment options available. 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). Log-linearity was tested for each continuous variable using fractional polynomials (20). In addition, male sex, diabetes, and an infection within 3 months before QFT were independently associated with a negative mitogen response, but not with a weak mitogen response, as compared with a normal response (Model 1, Table 2). Furthermore, our data for patients with microbiologically confirmed TB are illustrative. Clinical evaluation and additional tests (such as a chest radiograph, sputum smear, and culture) are needed to differentiate between a diagnosis of latent TB or active TB. Fourth, the mitogen response was associated with hospital length of stay and in-hospital mortality. 22. 13. previously reported that a lower mitogen response was associated with worse 1-year survival in TB patients (27). Applies only to results expressed in units of measure originally reported by the performing laboratory. -, Helwig U, Mller M, Hedderich J, Schreiber S. Corticosteroids and immunosuppressive therapy influence the result of QuantiFERON TB Gold testing in inflammatory bowel disease patients. It spreads from one person to another via tiny water droplets which are excreted into the air when an infected person coughs or sneezes. We observed that patients with negative and weak mitogen responses have similar characteristics, especially for immunodepression status, which was identified in, respectively, 58 and 52% of these patients, compared with 36% of patients with normal response. 10.1097/MPG.0000000000000205 In each final model, interactions between selected variables were systematically tested. Depressed T-cell interferon-gamma responses in pulmonary tuberculosis: analysis of underlying mechanisms and modulation with therapy. A False Discovery Rate (FDR) was applied to account for multiple comparisons, and the results are expressed in Q-values. Clin Microbiol Rev. These values do not apply to results that are converted to other units of measure. 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 . The QuantiFERON-TB Gold Plus collection kit contains the instructions for the collection and handling of (one each): (1) gray-top (with white ring), uncoated (nil); (2) green cap with white ring, TB1 tube; (3) yellow cap with white ring, TB2 tube; (4) purple top with white ring, mitogen-coated. QFT4. Huang C-T, Lee M-R, Ruan S-Y, Tsai Y-J, Wang J-Y, Yu C-J. After the blood sample is taken and analyzed, the QuantiFERON TB Gold test will render one of the following results: Negative or Normal. Decreasing mitogen response (normal, weak and negative, respectively) was associated with increasing length of hospital stay [median (interquartile range) 5 (3-13), 11 (5-21) and 15 (10-30) days; p < 0.001] and increasing hospital mortality (3, 7, and 15%; p < 0.001). Sepsis was considered as severe if requiring ICU admission. Akut fertzst kveten a teszt 2-8 ht mlva lesz pozitv. Valid values for a . However, interestingly, we found that both recent and ongoing infection were independent factors associated with a negative mitogen response. Tuberculosis (TB) was recorded if there were associated clinical-radiological signs of TB and it was confirmed with laboratory testing (Mycobacterium tuberculosis identification with culture and/or polymerase chain reaction). quantiferon mitogen value normal range. (2019) 158:49-54. doi: 10.1016/j.rmed.2019.10.004, Keywords: QuantiFERON, mitogen, infection, outcomes, mortality, Citation: Jacquier M, Binquet C, Manoha C, Audia S, Simonet-Lamm A-L, Casenaz A, Sow A-K, Piroth L and Blot M (2022) Beyond QuantiFERON-TB Results, the Added Value of a Weak Mitogen Response. TB is a severe illness with fatal consequences. LOINC. It can be assumed that lymphopenia and T-cell exhaustion, which are frequent in TB (17), explain this lack of sensitivity in connection to an altered mitogen response. In addition, sex, immunodepression and higher platelets were independently associated with a negative mitogen response, and diabetes was associated with a weak mitogen response when compared to the normal mitogen response group (Supplementary Table 3 and Supplementary Figure 2). 0000002253 00000 n Please enable it to take advantage of the complete set of features! official website and that any information you provide is encrypted The Mitogen minus Nil value serves as the positive control, demonstrating the successful responsiveness of the T lymphocytes in patient specimen. Blood samples must be processed within 16 hours after collection while white blood cells are still viable. 1. Drain PK, Bajema KL, Dowdy D, Dheda K, Naidoo K, Schumacher SG, et al. %%EOF Table 2. 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. Positive (>0.99 IU/ml) 6712: 65: Total number of cases: 40773: 96: What is a normal QuantiFERON mitogen value? The mitogen tube must demonstrate an interferon- value of 0.5 IU/ml higher than the value of the NIL tube. A negative IGRA does not rule out active TB disease; a number of studies have shown that up to a quarter of patients with active TB have negative IGRA results. 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). 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).

All age groups. (2006) 28:24-30. doi: 10.1183/09031936.06.00016906, 27. J Pediatr Gastroenterol Nutrit. They are cell-mediated immune-based blood tests that have revolutionised LTBI diagnosis and are increasingly recommended by national guidelines. endstream endobj 23 0 obj<>stream Identifying the situations that are associated with negative QFT performance could avoid unnecessary costs and diagnostic delay. (2012) 16:R112. . If a patient underwent several QFTs during the study period, only the first was retained for the analysis. (2010) 35:1179-82. The analysis for the first and second measurements across the full range of nil, mitogen, and TB responses showed mean differences of 0.1 IU/ml, 0.2 IU/ml, and 0.1 IU/ml, respectively. Finally, increasing C-reactive-protein (CRP) levels (15) or neutrophil/lymphocyte ratios are also positively correlated with indeterminate QuantiFERON-TB gold (16). All authors contributed to the article and approved the submitted version. Blot M, Zeggay A, Aho-Glele LS, Laborde C, Le Moing V, Chirouze C, et al. According to the FDA approved package insert[20] Quantiferon TB Gold In Tube has a consistent specificity of >99% in low risk individuals and a sensitivity as high as 92% in individuals with active disease, depending on setting and extent of disease. The clinical and biological characteristics of the three groups are compared in Table 1. 0000034863 00000 n 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. The mitogen response of lymphocytes to untreated or heat-treated PWM and heat-treated Con A was increased in 1 mM Ca2+-supplemented groups, whereas the response . 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). 702-800-2723Fax: 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).
