These results echo the results from the past studies. A study carried out at Florence, Italy, revealed that the proportion of positive scoring for TST was significantly lower in patients on treatment with steroids compared with the proportion of positive results in patients who were not receiving treatment with steroids.
Schatz et al. However, it is not statistically significant due to small number of patients but should be explored further in view of its clinical importance. In this study, consecutive patients with RA, fulfilling the inclusion criteria, were enrolled from the outpatient department and then grouped according to their therapy.
This led to disproportionate groups which is a limitation of the study. Another limitation of the study is that patients were on different forms and doses of different corticosteroids. Long acting immunosuppression may have affected results in some patients. This intermediate degree of TST positivity in group exposed to steroids in last 3 months but not in last 1 week could be because of differing magnitude and duration of immunosuppressive effect of different forms of steroids taken by the patients.
In such a situation TST cannot be relied upon for screening of latent tuberculosis. Our study suggests that steroid intake within the last 1 week significantly lowers the chances of tuberculin positivity. Therefore in patients with RA, before administration of biologicals, tuberculin test should be read with caution if there is history of recent steroid intake.

Because of a positive control in this assay, it is possible to identify those patients in which a result of tuberculosis testing is not available due to a lack of stimulation capacity of lymphocytes indeterminate result. Patients suffering from IBD are often treated with immunosuppressive agents, which may influence the results of tuberculosis testing. Methods: 50 consecutive patients were documented before introducing anti-TNF-treatment in this single centre study between April and April Results: For the period of one year data of 45 consecutive patients was available for statistical analysis.
A correlation between the indeterminate result and combination therapy of corticosteroids was found. The concomitant therapy of immunosuppressive agents lead to a lower IFN release but no significance was found. Conclusions: Steroid treatment and further combination therapy with immunosuppressive agents lead to a high risk of indeterminate QuantiFERON test.
A common recommendation to exclude tuberculosis infection is to perform a chest radiography, which might exclude granulomas over the size of 1 cm, a detailed travel history and TB exposures as well as to measure the skin reaction of purified protein derivates of M.
The PPD test is a delayed-type-hypersensitivity reaction test towards a mixture of more than different M.
An alternative diagnostic approach is to test the interferon gamma release as a specific reaction of T-cells on stimulation with M. Furthermore, it has a higher sensitivity and the possibility to detect an indeterminate result via a positive reaction control.
The therapeutic strategy in Crohn's disease and ulcerative colitis is the use of corticosteroids in the acute phase of inflammation and immunosuppressive agents like azathioprine and 6-mercaptopurine or methotrexate for maintenance of the remission phase.
The immunosuppressive therapy may influence also the test of latent tuberculosis. In the performance of the tuberculin skin test a positive control is not implicated, whereas a false indeterminate result cannot be detected.
We assessed the rate of indeterminate results of QuantiFERON test and its association with corticosteroid and immunosuppressive treatment. Consequently, we excluded these patients from all statistical analysis. This study was approved by the ethical committee of Lower Saxony, Hanover, Germany and was performed in concordance to Helsinki declaration. Laboratory parameters including liver enzymes, CRP, white blood cell count, haemoglobin, thrombocytes etc.
In short: one ml of whole venous blood was added to each of the three assay kit-tubes nil, mitogen, antigen. The tubes were transferred via courier to the performing laboratory for assay.
Indeterminate results were defined as increase less than 0. The primary point was to determine the influence of indeterminate results of the QuantiFERON test by immunosuppressive agents. Based on Kolmogorov—Smirmov tests normal distribution could not be assumed. Therefore we used median and quartile values box-whisker plots for data description.
The probability for a valuable test was predicted by a logistic regression model. For the logistic regression we included corticoid therapy immunosuppression, blood cell count of erythrocytes, leucocytes, thrombocytes, C-reactive protein, iron serum level, sex and the diagnosis of Crohn's disease or ulcerative colitis.
The dose depending curve Fig. Further patient data is presented in Table 1. One patient out of 45 corresponding to 2. To describe the difference between the patient group receiving corticosteroid, corticosteroids and immunosuppression in combination or no concomitant medication we used the Mann—Whitney- U -test.
The indeterminate results were associated with corticosteroid treatment and stronger association was found in patients with combined immunosuppressive therapy and corticosteroid treatment. These findings depend upon the dose. A daily dose of 15 mg or more showed a high risk for indeterminate results.
We analysed the stimulation capacity in dependence of immunosuppressive therapy. The presented study shows the effect of anti-inflammatory agents on the outcome of testing the latent tuberculosis infection. Corticosteroid treatment increases the risk for indeterminate results.
Moreover, the combination of immunosuppressive medication with corticosteroids further increases the risk for an indeterminate result of the QuantiFERON test. Until now it is unclear, if this is due to the general immunologic situation of patients suffering from Crohn's disease or ulcerative colitis or not. In the past the suspicion of modified immunologic reactions against tuberculosis agents in inflammatory bowel disease was discussed Fig.
The therapeutic strategy against Crohn's disease and ulcerative colitis is the use of corticosteroids in the acute phase of inflammation and immunosuppressive agents like azathioprine and 6-mercaptopurine or methotrexate for maintenance of remission phase. In patients with fistula disease and severe inflammation or failure to corticoid and or immunosuppressive therapy the treatment with anti-TNF-antibodies like Infliximab, Adalimuab or Certolizumab will be induced.
In the presented patient group, However, in the presented patient population there was only one patient tested positively for latent tuberculosis infection. We cannot comment on the risk for undiagnosed latent tuberculosis reaction because of the low number of patients with latent tuberculosis.
We performed risk factors for the development of an indeterminate result and found that the corticosteroid therapy is the main risk factor for false negative results. The risk increases with higher doses of corticosteroids and is supported by immunosuppressive agents. This is related to the reduced stimulation capacity of lymphocytes when patients receive corticoid treatment and is further reduced in case of concomitant therapy with immunosuppressive agents.
The stimulation capacity is significantly higher in patients under immunosuppressive therapy when the daily corticoid dose is less than 15 mg prednisolone equivalent. However, the presented study population might show a low rate of latent tuberculosis infections compared to other studies, 14,15,22 but, nonetheless, our data represents the low incidence of tuberculosis infection in the northwest of Germany.
In the presented study a high rate of an indeterminate results occurred compared to the studies of Schoepfer at al. This might be due to the German recommendation of use of anti-TNF-therapy in patients with refractory disease to immunosuppressive agents or corticosteroids. A couple of months ago Papay et al. However, in the IBD-cohort no data on the combined therapy with immunosuppressive agents and corticosteroids was available whereas in the second cohort data on corticosteroids is available and leads to similar results as the main risk factor for indeterminate results of the IFN-gamma release assay.
Moreover we could show in the presented study an influence depending on the dose of corticosteroids on the results of QuantiFERON-test. In conclusion, we can confirm the data of Papay et al. Moreover, we found a high correlation between the combination of immunosuppressive agents and corticosteroids in the presented study. Therefore, we recommend reducing the corticosteroid treatment to less than 15 mg prednisolone per day if corticosteroid treatment is combined with immunosuppressive agents before starting the QuantiFERON-test.
If the clinical situation of the patient requires a high dose of corticosteroid treatment and does not allow a dose reduction of corticosteroids, we recommend excluding latent tuberculosis infection by chest-x-ray and detailed medical history. The study-setup and the low patient number do not allow a comment on the risk for false negative results and no comparison to the tuberculin skin test. Travis S. Stange E. Lemann M. Oresland T.

It is vastly described in the literature that Prednisone treatment along with chronic inflammatory disease depresses TST reaction. Nevertheless, few studies. Prednisolone treatment was strongly associated with negative TST, AOR ( (p= ), and with an increased risk of indeterminate QFT-IT results AOR . Our study suggests that steroid intake within the last 1 week significantly lowers the chances of tuberculin positivity. Therefore in patients with RA, before. Currently, the cut-off size of a positive Tuberculosis skin test (TST) among immunosuppressed patients is 5 mm. It is vastly described in. The Mantoux tuberculin skin test (TST) is the millimeters is considered positive in day of prednisone for 1 month or. With time as further researches negated the etiological role of mycobacteria in RA, the relationship between the two took a turn so that the occurrence of two diseases together was not considered to be dependent on each other. Deville, N. Demographic profile of patients grouped according to steroid intake.Background Reactivation of latent tuberculosis TB is a major complication of tumor necrosis factor alpha inhibitors TNF-i. Therefore, screening for latent TB is recommended before initiation of this treatment. Currently, the cut-off size of a positive Tuberculosis skin test TST among immunosuppressed patients is 5 mm. It is vastly described in the literature that Prednisone treatment along with chronic inflammatory disease depresses TST reaction. Nevertheless, few studies reject this hypothesis.
TST measurements, Prednisone and Methotrexate doses and treatment durations were recorded. Active tuberculosis TB was excluded by chest X-ray and patient's history. A control group, was randomly selected from healthy patients who had a TST at the pulmonology clinic in our institution. We compared the results of the mean TST reaction size between the following three groups: RA patients with current prednisone treatment, RA patients without history of prednisone treatment and healthy individuals.
A correlation between this score and the size of the TST reaction was assessed using Pearson's correlation coefficient r.
Results 43 mean age There was no significant difference in mean TST between these three groups 5. Therefore, we conclude that the criterion of 5 mm TST reaction defining latent TB infection in our population should be re-evaluated. Larger studies are needed to verify our results.
