therapies with tumor necrosis factor-alpha antagonists (anti-TNF-α) have revolutionized the prognosis of rheumatic diseases. Their use, however, is accompanied by certain risks. One of the adverse effects to be taken into account is the increase in the number of infections,<a class="elsevierStyleCrossRef" href="#bib0055"><span class="elsevierStyleSup">1</span></a> especially of the opportunistic and granulomatous types, such as tuberculosis (TB). Although the risk is increased with all the anti-TNF-α agents, there are data that suggest a higher risk among patients who are treated with monoclonal antibodies when compared with those receiving the fusion protein.<a class="elsevierStyleCrossRef" href="#bib0060"><span class="elsevierStyleSup">2</span></a></p><p id="par0010" class="elsevierStylePara elsevierViewall">Since 2002, the United States Food and Drug Administration recommends screening for TB, and chemoprophylaxis in case of latent TB infection, before initiating anti-TNF-α agents. Prophylaxis is recommended in the following situations<a class="elsevierStyleCrossRef" href="#bib0065"><span class="elsevierStyleSup">3</span></a>: (a) recent exposure to confirmed TB; (b) a history of TB without proper treatment; and (c) positive Mantoux test and/or radiographic evidence of sequelae of TB. This measure has dramatically reduced the incidence of TB among patients receiving anti-TNF-α<a class="elsevierStyleCrossRef" href="#bib0070"><span class="elsevierStyleSup">4</span></a>; however, cases of TB continue to be detected, despite an initial negative screening test.<a class="elsevierStyleCrossRef" href="#bib0075"><span class="elsevierStyleSup">5</span></a> This could be due to either a reactivation of latent TB with a negative screening test (false negative) or a primary tuberculous infection. The time to development of active TB after initiation of anti-TNF-α therapy may prove to be the clue to whether reactivation or primary infection should be suspected, as reactivation can be expected to occur within a short time after initiation of immunosuppressive therapy. However, a tuberculous infection after a long period of treatment suggests a primary infection, although it has not yet been possible to establish a clear time limit to distinguish between the 2 origins.<a class="elsevierStyleCrossRef" href="#bib0080"><span class="elsevierStyleSup">6</span></a></p><p id="par0015" class="elsevierStylePara elsevierViewall">Given its relevance, the objective of this study is to review the cases of active TB in which the patients presumably developed a primary tuberculous infection during treatment with anti-TNF-α agents, despite an initial negative screening test.</p></span><span id="sec0010" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0080">Material and Methods</span><p id="par0020" class="elsevierStylePara elsevierViewall">We performed a retrospective review of the registry of patients receiving biologic therapy in the rheumatology department of Hospital General Universitaria de Alicante, in southeastern Spain, which included a total of 771 patients treated between 1999 and 2012 (year of the study). We selected the medical records of patients who met the following inclusion criteria: (a) current or previous treatment with anti-TNF-α; (b) negative results in TB screening prior to treatment with anti-TNF-α; (c) active TB diagnosed during treatment with anti-TNF-α; and (d) suspected primary tuberculous infection; for this study, primary tuberculous infection was considered if the diagnosis had been made after treatment with the biologic agents for at least 12 months.<a class="elsevierStyleCrossRef" href="#bib0085"><span class="elsevierStyleSup">7</span></a> The TB screening protocol in our center consists of the Mantoux test (1 or 2 steps), chest radiography, and microscopic study of sputum and urine specimens, when appropriate.

In the remaining 4 patients, screening (including 2-step Mantoux test and chest radiography) was negative. Two of them developed TB during the first year of anti-TNF-α therapy and, therefore, were considered to have a reactivation of latent TB, with false negative results in the screening test.

Her response to nonsteroid anti-inflammatory drugs (NSAID) was suboptimal and treatment with adalimumab was begun in 2006, following screening for TB (at the time of the Mantoux test, she was only being treated with NSAID). In 2009, after 35 months of adalimumab, she presented with fever, dry cough, odynophagia, and headache, and was feeling generally unwell. Pulmonary computed tomography revealed a mass measuring 4<span class="elsevierStyleHsp" style=""></span>cm in the anterior segment of left upper lobe, with suprahilar and prevascular adenopathy (<a class="elsevierStyleCrossRef" href="#fig0005">Fig. 1</a>).

Initially, he had been treated with sulfasalazine and NSAID, but in 2003, monotherapy with infliximab was begun because of the persistence of disease activity. Prior to the change in treatment, the patient underwent screening for TB while he was still being treated with sulfasalazine and NSAID. In 2012, after 107 months of treatment with infliximab, he developed a cough with expectoration, followed by dyspnea, fever and constitutional symptoms. Plain radiography revealed a suprahilar infiltrate in right lung and pulmonary computed tomography confirmed the presence of an alveolar infiltrate in segment 3 of right lung, with presence of adjacent hilar adenopathy. The Mantoux test was repeated, which this time was positive (17<span class="elsevierStyleHsp" style=""></span>mm), and <span class="elsevierStyleItalic">M. tuberculosis</span> was isolated in both sputum and in the bronchial biopsy. After 2 weeks of tuberculostatic therapy with isoniazid, pyrazinamide, rifampicin and ethambutol, an increase in the cholestatic enzymes was detected, and ultrasound revealed the presence of hepatomegaly and there were multiple hypoechoic images in spleen. A liver biopsy confirmed the presence of tuberculous infection (<a class="elsevierStyleCrossRef" href="#fig0010">Fig. 2</a>).

Six months after the initiation of tuberculostatic therapy, due to a marked inflammatory activity of his ankylosing spondylitis, the decision was made to reinitiate anti-TNF-α therapy with etanercept.

In our series, we detected 2 cases involving patients with initial negative screening who developed active TB after 35 and 107 months of treatment with anti-TNF-α. It seems reasonable to assume that these were cases of primary tuberculous infection, since the disease appeared after a long period of immunosuppression. We used 12 months as the lower limit at which a case can be considered new TB infection. This date is arbitrary and is debatable, but in a series 703 patients treated with anti-TNF-α in the United Kingdom, all the reactivations occurred within the first year of treatment. It is also supported by the fact that, using a mathematical model, Wallis<a class="elsevierStyleCrossRef" href="#bib0080"><span class="elsevierStyleSup">6</span></a> estimated that, after one year of treatment with infliximab, the predominant cause of TB would be primary infection. In any case, we cannot rule out the possibility that cases of TB detected during the first year of treatment could also be due to new infection.</p><p id="par0060" class="elsevierStylePara elsevierViewall">The persistence of the risk of TB during treatment with anti-TNF-α leads to the question as to whether TB screening should be repeated periodically.<a class="elsevierStyleCrossRef" href="#bib0090"><span class="elsevierStyleSup">8</span></a> Probably, by analogy with a proposal issued by the United States Centers for Disease Control and Prevention in Atlanta, Georgia, for patients with human immunodeficiency virus infection,<a class="elsevierStyleCrossRef" href="#bib0095"><span class="elsevierStyleSup">9</span></a> the possibility of screening for TB each year throughout the duration of anti-TNF-α therapy has been considered; however, this strategy has not been formally tested in rheumatic patients and raises certain doubts, especially if there is no clinical suspicion and has been no possible contact with an infectious patient (positive Combe sign). The goal is the detection of latent tuberculous infection; however, should these patients contract the disease, they would probably have active TB, as in the cases reported here, because of the deficient granulomatous inflammatory response secondary to the biologic therapy. Another point that should be taken into account is a possible state of immunological anergy when a patient is undergoing the Mantoux test, since factors such as immunosuppression (especially corticosteroids) and age could result in false negatives.<a class="elsevierStyleCrossRef" href="#bib0100"><span class="elsevierStyleSup">10</span></a></p><p id="par0065" class="elsevierStylePara elsevierViewall">In short, we feel it necessary to stress the fact that the risk of developing TB persists in patients being treated with anti-TNF-α, even when initial screening was negative. Despite its low frequency in our series, the associated rates of morbidity and mortality indicate that a high suspicion should be maintained throughout the entire period of treatment with anti-TNF-α.</p></span><span id="sec0025" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0095">Ethical Disclosures</span><span id="sec0030"
