Abstract
OBJECTIVES Pulmonary nontuberculous mycobacterial disease (pNTM) is a common pulmonary complication of rheumatoid arthritis (RA), but their association has rarely been researched. We aimed to reveal the clinical characteristics of RA with pNTM. METHODS Among all the RA patients who visited Tenri hospital from April 2017 to March 2018, we enrolled those fulfilling the 2007 ATS/IDSA diagnostic criteria of pNTM, and sex- and age- matched control group at a ratio of 1:5. Demographic characteristics were compared between the two groups. RESULTS Among 865 RA patients, 35 (4.0%) patients were complicated with pNTM. RA patients with pNTM had significantly lower BMI and higher rheumatoid factor (RF) and anti-citrullinated protein antibody (ACPA) positivity. Bronchiectasis was the most frequent lesion, followed by clusters of small nodules, patchy consolidation and cavity. Multivariable logistic regression analysis revealed bronchiectasis as a strong independent associated factor of pNTM. Treatment for pNTM was needed in 14 of the 35 (40%) RA patients with pNTM and sputum negative conversion was accomplished in 11 of the 14 cases (78.6%). CONCLUSIONS RA patients with lower BMI, RF/ACPA positivity, and bronchiectasis were associated with pNTM. Treatment for pNTM may attain sputum negative conversion and radiological improvement in patients with RA.

Abstract
Mycobacterium haemophilum is a rare pathogen belonging to the group of slowly growing nontuberculous mycobacteria (NTM) that can cause infections, especially in immunocompromised patients. Detection by culturing is difficult because M. haemophilum only grows under special cultivation conditions. Therefore, it is believed that the pathogen is too rarely identified as a cause of disease overall. In addition to patients with severe immunodeficiency, e.g. due to acquired immunodeficiency syndrome (AIDS), chemotherapy or immunosuppression after transplantation, patients with underlying rheumatic diseases are increasingly described in the literature, who are at risk due to the immunosuppressive treatment regimen. Clinically, ulcerative skin alterations, lymphadenopathy and arthropathy are in the foreground. In immunosuppressed patients with unclear skin lesions, infections due to M. haemophilum should be considered and specific microbiological diagnostics should be initiated.

Abstract
Rapidly growing mycobacteria (RGM) has gained increasing clinical importance, and treatment is challenging due to diverse drug resistance. The minimum inhibitory concentrations (MIC) of 13 antimicrobial agents using modified broth microdilution and E-test were determined for 32 clinical isolates of RGM, including Mycobacterium abscessus (22 isolates) and Mycobacterium fortuitum (10 isolates). Our results showed high rates of resistance to available antimicrobial agents. Amikacin remained highly susceptible (87.5%). Clarithromycin was active against the isolates of M. abscessus (95.5%), and M. fortuitum (50%), but 36.4% and 20% had inducible macrolide resistance, respectively. Rates of susceptibility to tigecycline were 68.2–70%, and linezolid 45.5–50%, respectively. The quinolones (ciprofloxacin and moxifloxacin) showed better in vitro activity against M. fortuitum isolates (50% susceptibility) than the M. abscessus isolates (31.8% susceptibility). The susceptibilities to other conventional anti-mycobacterial agents were poor. The MICs of E-test were higher than broth microdilution and may result in reports of false resistance. In conclusion, the implementation of the modified broth microdilution plates into the routine clinical laboratory workflow to provide antimicrobial susceptibility early, allows for the timely selection of appropriate treatment of RGM infections to improve outcome.

Abstract
Mycobacterium haemophilum is a rarely encountered pathogen that is difficult to identify given its unique growth requirements. It is most often seen in adult patients who are immunosuppressed due to advanced HIV or haematological malignancy. Our case highlights a typical presentation of an atypical pathogen in a patient with rheumatoid arthritis receiving anti-tumour necrosis factor therapy. This case represents an important patient population in whom this previously rare infection is increasingly common.

Abstract
DISCLAIMER In an effort to expedite the publication of articles , AJHP is posting manuscripts online as soon as possible after acceptance. Accepted manuscripts have been peer-reviewed and copyedited, but are posted online before technical formatting and author proofing. These manuscripts are not the final version of record and will be replaced with the final article (formatted per AJHP style and proofed by the authors) at a later time. PURPOSE To provide an updated review of the diagnosis and pharmacotherapy of nontuberculous mycobacteria pulmonary disease (NTM-PD) and summarize guideline recommendations for an interdisciplinary treatment approach. SUMMARY A systemic approach was taken in which all articles in English in MEDLINE and PubMed were reviewed. DAILYMED was used to assess drug package inserts. Analysis of NTM treatment guidelines is summarized in the article with a focus on medications, dosing, interactions, and medication monitoring. CONCLUSION It is critical to manage patients with NTM with a multidisciplinary team approach. Treatment is prolonged and expensive, and the potential for drug toxicity, adverse effects, and drug interactions requires monitoring. Clinical pharmacists play a role in the management of NTM.

Abstract
Background Real-world data on treatment safety and outcome of pulmonary tuberculosis (PTB) in patients with rheumatic diseases (RDs) are scarce. This study explored the therapeutic issues of standard first-line anti-tuberculosis (TB) medication in patients in whom PTB complicated autoimmune RDs. Methods Observational, retrospective study was conducted in an intermediate TB burden area, South Korea. We evaluated the safety profile of, and adherence to, standard first-line anti-TB medication in PTB patients with systemic RD and assessed the long-term treatment outcomes, up to 84 months after treatment completion. Results We included 37 patients suffering from PTB with RD (case group) and 191 without RD (control group). Rheumatoid arthritis (RA) was the most common RD (24 PTB patients, 64.9%). The frequency of severe adverse drug reactions (ADRs) was significantly higher in the case group than in the control group (36.1% vs. 12.5%, P=0.003). Severe gastrointestinal problems were the most commonly observed ADRs, with a high frequency consistently noted in both groups. Changes in first-line anti-TB medication because of severe ADRs were significantly more frequent in the case group, compared with the control group (19.4% vs. 8.3%, P=0.046). No significant between-group difference was evident in terms of long-term unfavorable outcomes (including relapse and mortality) (5.7% cases vs. 1.2% controls, P=0.146). Conclusions Clinicians may encounter difficulties when treating PTB in patients with RD. Despite the favorable long-term outcomes of RD patients, the outcomes of individual patients such as those with systemic lupus erythematosus (SLE) should be interpreted with caution during post-therapy follow-up.

Abstract
Purpose Although a significant number of reports on new therapeutic options for refractory Kawasaki disease (KD) such as steroid, infliximab, or repeated intravenous immunoglobulin (IVIG) are available, their effectiveness in reducing the prevalence of coronary artery lesions (CAL) remains controversial. This study aimed to define the clinical characteristics of patients with refractory KD and to assess the effects of adjuvant therapy on patient outcomes. Methods We performed a retrospective study of 38 refractory KD patients from January 2012 to March 2015. We divided these patients into 2 groups: group 1 received more than 3 IVIG administration+ steroid therapy, (n=7, 18.4%), and group 2 patients were unresponsive to initial IVIG and required steroid therapy or second IVIG (n=31, 81.6%). We compared the clinical manifestations, laboratory results, and echocardiographic findings between the groups and examined the clinical utility of additional therapies in both groups. Results A significant difference was found in the total duration of fever between the groups (13.0±4.04 days in group 1 vs. 8.87±2.30 days in group 2; P=0.035). At the end of the follow-up, all cases in group 1 showed suppressed CAL. In group 2, coronary artery aneurysm occurred in 2 patients (6.4 %). All the patients treated with intravenous corticosteroids without additional IVIG developed CALs including coronary artery aneurysms. Conclusion No statistical difference was found in the development of CAL between the groups. Prospective, randomized, clinical studies are needed to elucidate the effects of adjunctive therapy in refractory KD patients.

Abstract
Background Biological agents inhibiting TNF-α and other molecules involved in inflammatory cascade have been increasingly used to treat rheumatoid arthritis (RA). However, it remains controversial whether biological agents can be used safely in a patient with an underlying chronic infectious disease. Case presentation A 63-year-old woman who had been treated with tocilizumab (TCZ), anti-interleukin-6 receptor antibody, for RA presented to our outpatient clinic due to hemoptysis. She was diagnosed with pulmonary Mycobacterium avium complex (MAC) infection, and high-resolution computed tomography (HRCT) showed a single cavitary lesion in the right upper lobe. After diagnosis of pulmonary MAC disease, TCZ was discontinued and combination chemotherapy with clarithromycin, rifampicin, ethambutol and amikacin was started for MAC pulmonary disease. Since the lesion was limited in the right upper lobe as a single cavity formation, she underwent right upper lobectomy. As her RA symptoms were deteriorated around the operation, TCZ was resumed. After resumption of TCZ, her RA symptoms improved and a recurrence of pulmonary MAC infection has not been observed for more than 1 year. Conclusion This case suggested that TCZ could be safely reintroduced after the resection of a pulmonary MAC lesion. Although the use of biological agents is generally contraindicated in patients with pulmonary MAC disease, especially in those with a fibrocavitary lesion, a multimodality intervention for MAC including both medical and surgical approaches may enable introduction or resumption of biological agents.

Abstract
OBJECTIVE To review patients with rheumatoid arthritis (RA) receiving biologic therapy following a diagnosis of nontuberculous mycobacterial (NTM) lung disease and to evaluate disease deterioration according to clinical and radiological features and anti-NTM therapy. METHODS We retrospectively analyzed medical records of 11 human immunodeficiency virus-negative patients with RA (median age, 64 years) receiving biologic therapy following diagnosis of NTM lung disease. RESULTS NTM species included Mycobacterium avium complex in 9 patients (81.8%) and M. gordonae in 2 (18.2%). Underlying respiratory disease was present in 6 patients (54.5%), and most (81.8%) had radiographic features of nodular/bronchiectatic disease. Extent of NTM disease was 1-2 pulmonary lobes in 6 patients (54.5%), 3-4 lobes in 5 patients (45.5%), and 5-6 lobes in none. The results of radiological evaluations were unchanged or improved in 7 patients (63.6%) and worsened in 4 (36.4%). Radiological outcome was worse in patients with poor RA control despite their receiving biologic therapies for RA. Two of 3 patients receiving anti-NTM therapy as initial management for NTM improved, and 1 worsened. Three of 4 patients with worsened radiological outcome had high erythrocyte sedimentation rate (> 50 mm/h). CONCLUSION Radiological deterioration was not observed in the majority of patients with RA receiving biologic therapy with NTM lung disease, and radiological outcome of pulmonary NTM was favorable in some patients undergoing anti-NTM therapy. Further studies focusing on disease deterioration according to biologic therapy received during NTM followup are warranted to determine appropriate treatment of RA patients with NTM lung disease.

Abstract
BACKGROUND The aims of this study were to determine the incidence of tuberculosis (TB) and nontuberculous mycobacteria (NTM) lung disease in patients who were treated with tumor necrosis factor (TNF) antagonists in South Korea and to evaluate their clinical characteristics. METHODS We surveyed all patients (N = 509) who were treated with TNF antagonists at Severance Hospital, South Korea, between January 2002 and December 2011. We reviewed the patients' medical records and collected microbiological, radiographic, and clinical data, including the type of TNF blocker(s) used and the results of tuberculin skin tests and interferon-gamma release assays. RESULTS Rheumatoid arthritis (43.6 %) and ankylosing spondylitis (27.9 %) were the most common diseases in the patients treated with TNF antagonists. Patients received etanercept (33.4 %), infliximab (23.4 %), or adalimumab (13.2 %). The remaining patients received two or more TNF antagonists (30 %). Nine patients developed TB, and four patients developed NTM lung disease. After adjustment for age and sex, the standardized TB incidence ratio was 6.4 [95 % CI 3.1-11.7] compared with the general population. The estimated NTM incidence rate was 230.7 per 100,000 patients per year. CONCLUSIONS Our results show that mycobacterial infections increase in patients treated with TNF antagonists. The identification of additional predictors of TB for the treatment of latent tuberculosis infection and the careful monitoring and timely diagnosis of NTM-related lung disease are needed for patients who receive long-term therapy with TNF antagonists.

Abstract
Mycobacterium abscessus complex is the most virulent of rapidly growing mycobacteria causing invasive lung disease. To better delineate clinical pediatric experience and outcomes with M. abscessus complex, we retrospectively gathered 5-year data on M. abscessus complex infection and outcomes in a large, hospital-based pediatric pulmonary center. Patients were selected from the database of the microbiology department at Miller Children's Hospital in Long Beach, CA. Patients had at least one positive pulmonary isolate for M. abscessus complex from February 2006 to May 2011. Treatment modality data were collected and successful therapy of disease was determined as clearance of M. abscessus complex infection after antibiotics proven by culture negative respiratory isolate within at least 12 months of therapy initiation. Two cystic fibrosis patients with M. abscessus complex were identified, one with failed therapy and the other with stable pulmonary status despite persistent isolation. One primary ciliary dyskinesia patient had successful clearance of M. abscessus complex, however is now growing M. avium intracellulare. A patient with no prior medical history was successfully treated with antimycobacterial therapy. Eleven patients with neuromuscular disorders had tracheal aspirates positive for M. abscessus complex. None were treated due to stable lung status and all but two had spontaneous clearance of the mycobacteria. The two remaining persist with sporadic isolation of M. abscessus complex without clinical significance. We concluded that patients with tracheostomy associated M. abscessus complex infections do not appear to require treatment and often have spontaneous resolution. Cystic fibrosis or primary ciliary dyskinesia patients may have clinical disease warranting treatment, but current antimycobacterial therapy has not proven to be completely successful. As M. abscessus complex gains prevalence, standardized guidelines for diagnosis and therapy are needed in the pediatric population. Multicenter cohort analysis is necessary to achieve such guidelines.

Abstract
A symptomatic patient had repeatedly positive cultures of Mycobacterium avium subsp. hominissuis after exposure to a hot tub contaminated with M. avium subsp. hominissuis. The pulmonary and tub water isolates were indistinguishable by IS1245 RFLP as well as rep-PCR typing. Discontinued use of the hot tub resulted in culture conversion.

Abstract
Mycobacterium haemophilum is a slowly growing acid-fast bacillus (AFB) belonging to the group of nontuberculous mycobacteria (NTM) frequently found in environmental habitats, which can colonize and occasionally infect humans and animals. Several findings suggest that water reservoirs are a likely source of M. haemophilum infections. M. haemophilum causes mainly ulcerating skin infections and arthritis in persons who are severely immunocompromised. Disseminated and pulmonary infections occasionally occur. The second at-risk group is otherwise healthy children, who typically develop cervical and perihilar lymphadenitis. A full diagnostic regimen for the optimal detection of M. haemophilum includes acid-fast staining, culturing at two temperatures with iron-supplemented media, and molecular detection. The most preferable molecular assay is a real-time PCR targeting an M. haemophilum-specific internal transcribed spacer (ITS), but another approach is the application of a generic PCR for a mycobacterium-specific fragment with subsequent sequencing to identify M. haemophilum. No standard treatment guidelines are available, but published literature agrees that immunocompromised patients should be treated with multiple antibiotics, tailored to the disease presentation and underlying degree of immune suppression. The outcome of M. haemophilum cervicofacial lymphadenitis in immunocompetent patients favors surgical intervention rather than antibiotic treatment.

Abstract
Mycobacterium genavense is an opportunistic non-tuberculous mycobacterium previously mostly associated with HIV-infected patients with CD4 counts below 100/μL. In this retrospective observational study of medical charts we studied all Dutch patients in whom M. genavense was detected between January 2002 and January 2010. Of the 14 patients identified, 13 (93%) showed clinically relevant M. genavense disease. All patients with M. genavense disease were severely immunocompromised, including HIV-infected patients, solid organ transplant recipients, those with chronic steroid use in combination with other immune modulating drugs, recipients of chemotherapy for non-Hodgkin lymphoma, and those with immunodeficiency syndromes. Two patients had non-disseminated pulmonary M. genavense disease. Of the 12 patients treated, eight (75%) showed a favourable outcome. Four patients died in this study, three despite treatment for M. genavense disease. We conclude that M. genavense is a clinically relevant pathogen in severely immunocompromised patients that causes predominantly disseminated disease with serious morbidity and mortality. M. genavense is increasingly seen among non-HIV immunocompromised patients.

Abstract
Objective This study was performed to evaluate the radiological features of and therapeutic responses to pulmonary disease caused by nontuberculous mycobacteria (NTM) in the setting of biological therapy for rheumatoid arthritis (RA). Methods We conducted a retrospective chart review of 13 patients from multiple centers who had developed pulmonary NTM disease during biological therapy for RA, including infliximab, etanercept, adalimumab, and tocilizumab. Results Most cases were asymptomatic or resulted in only common-cold-like symptoms. Abnormalities in computed tomography (CT) imaging were protean and frequently overlapped. The most predominant pattern was nodular/bronchiectatic disease (six cases), followed by alveolar infiltrate (three cases), cavitary disease (two cases), and pulmonary nodules (two cases). In most cases, pulmonary NTM disease had spread from a preexisting lesion; in particular, bronchial/bronchiolar abnormalities. In three cases, one or more nodular lesions with or without calcification were a focus of disease. Following the discontinuation of biological agents, most patients responded to anti-NTM therapy. Two patients showed no exacerbation in the absence of any anti-NTM therapy. In one patient, restarting tocilizumab therapy while continuing to receive adequate anti-NTM therapy produced a favorable outcome. In two other patients with a previous history of pulmonary NTM disease, introducing biological therapy led to recurrence, but anti-NTM therapy was effective in these patients. Conclusion CT abnormalities of pulmonary NTM disease in RA patients receiving biological therapy were variable, but were not unique to this clinical setting. NTM disease can spread from preexisting structural abnormalities, even if they are minute. Contrary to our expectations, the therapeutic outcomes of pulmonary NTM disease were favorable in these patients.

Abstract
Continuation of anti-tumor necrosis factor-α (TNFα) therapy generally has not been recommended for patients who have developed nontuberculous mycobacterial (NTM) diseases; in daily practice, however, we often encounter patients with refractory rheumatoid arthritis (RA) who experience uncontrollable flares following withdrawal of anti-TNFα agents. Here, we report a case of pulmonary NTM disease caused by Mycobacterium intracellulare occurring in a patient with refractory RA undergoing etanercept therapy. Since there was the concern of an exacerbation of RA symptoms, etanercept was continued during anti-NTM therapy. The patient's pulmonary symptoms and radiological abnormalities were found to have markedly improved in a relatively short time period after beginning the anti-NTM therapy. Additionally, her RA symptoms were adequately controlled without the occurrence of any unexpected adverse events. The continuation of etanercept therapy may be a safe option during anti-NTM therapy if patients' underlying diseases would otherwise be difficult to control. Strictly supervised anti-NTM therapy and patients' informed consent are mandatory. We review the medical literature on NTM disease associated with anti-TNFα therapy for rheumatic diseases and discuss the safety of simultaneous use of anti-TNFα agents in patients during anti-NTM therapy.

Abstract
OBJECTIVE Lung disease is commonly encountered in rheumatological practice either as a manifestation of the underlying condition or as a consequence of using disease-modifying therapies. This has been particularly apparent with the TNF-α antagonists and exacerbations of interstitial lung disease (ILD). In view of this, we undertook a review of the current literature to identify non-infectious pulmonary complications associated with the newer biologic agents used for the treatment of rheumatic conditions. METHODS A systematic literature review (SLR) was conducted using PubMed, the Cochrane Library and EMBASE for reviews, meta-analyses, clinical studies and randomized controlled trials, case studies and series, published up to June 2010 using the terms rituximab (RTX), certolizumab, golimumab (GOL), tocilizumab (TCZ) and abatacept in the advanced search option without limitations. In addition, abstracts from International Rheumatology conferences and unpublished data from the Food and Drug Administration, the European Medicines Agency and drug manufacturers were used to complement our search. References were reviewed manually and only those articles that suggested a potential relationship between the biological agent and lung toxicity, following exclusion of other causes, were included. RESULTS Reported non-infectious pulmonary adverse events with TCZ included a fatal exacerbation of RA-associated ILD, new-onset ILD, idiopathic pulmonary fibrosis and allergic pneumonitis, as well as three cases of microbiological culture-negative pneumonia. Although RTX had a higher incidence of pulmonary toxicity, only 7 of the 121 cases reported involved rheumatological diseases. GOL treatment was associated with four cases of non-infectious pulmonary toxicity and two cases of pneumonia with negative microbiological studies. There were no episodes of pulmonary toxicity identified for either certolizumab or abatacept. CONCLUSION Our results highlight an association between the use of newer biologic agents (TCZ, RTX and GOL) and the development of non-infectious parenchymal lung disease in patients with RA. Post-marketing surveillance and biologic registries will be critical for detecting further cases of ILD and improving our understanding of the pathophysiology of this process. As the use of these drugs increases, clinicians must remain vigilant for potential pulmonary complications and exercise caution in prescribing biologic therapies, particularly to rheumatological patients with pre-existing ILD.

Abstract
In the Netherlands, 1.4% of tuberculosis (TB) cases are caused by Mycobacterium bovis. After we admitted 3 patients with M. bovis infections to our reference hospital, we conducted a retrospective analysis of all M. bovis disease in the Netherlands during 1993–2007. We analyzed data from 231 patients for clinical, demographic, treatment, and outcome characteristics and for risk factors. Most patients were native Dutch (n = 138; 59.7%) or Moroccan (n = 54; 23.4%). Disease was mainly extrapulmonary (n = 136; 58.9%). Although 95 patients had pulmonary disease, person-to-person transmission did not occur, as shown by structural DNA fingerprinting analysis. Lymph node TB was more likely to develop in women (p<0.0001), whereas pulmonary M. bovis disease developed more frequently in men (p<0.0001). Diagnosis was accurate but delayed and led to inadequate treatment in 26% of the cases. Proportion of deaths from M. bovis disease was higher than that for M. tuberculosis disease.

Abstract
Tocilizumab is a humanized anti-IL-6 receptor monoclonal antibody, which binds to circulating soluble IL-6 receptor and membrane-expressed IL-6 receptor, inhibiting IL-6 binding to both forms of IL-6 receptor. Several Phase III clinical trials demonstrate the clinical efficacy of tocilizumab as monotherapy or with disease-modifying anti-rheumatic drugs for adult patients with moderately to severely active rheumatoid arthritis. Tocilizumab in combination with methotrexate after 24 weeks of treatment could induce disease remission in 30% of patients with rheumatoid arthritis refractory to anti-TNF antagonist therapy. The most common adverse reactions reported in clinical studies are upper respiratory tract infection, nasopharyngitis, headache, hypertension and mild, reversible increases in alanine aminotransferase enzymes. Serious adverse reactions include infections, gastrointestinal perforations and hypersensitivity reactions, including anaphylaxis. The clinical efficacy and safety of tocilizumab has led to the approval of this innovative drug for the treatment of rheumatoid arthritis in more than 70 countries worldwide.

Abstract
The pathogenesis of Mtb depends in part on cytokine cross-regulation between macrophages and T cells in host immunity. Th17 cells produce IL-17A to induce granuloma formation and to restrict mycobacterial dissemination. IL-17A also mediates cytokine responses induced by proinflammatory cytokines such as TNF-α. Our previous results showed that BCG induces IL-6, IL-10, and TNF-α via activity of protein kinases, including dsRNA-activated serine/threonine protein kinase and glycogen synthase kinase-3 in primary human monocytes. Therefore, we investigated whether IL-17A, upon its induction by BCG, plays an additional role to aid the production of downstream proinflammatory cytokines in macrophages. Here, we showed that IL-17A enhanced IL-6 mRNA and protein levels inducible by BCG in a time- and dose-dependent manner, whereas it had no effect on IL-10 and TNF-α production. We also demonstrated that IL-17A activated the phosphorylation of ERK1/2 triggered by BCG. With the use of a specific chemical inhibitor of a MAPK/ERK-activating kinase (MEK1/2), we confirmed the correlation between the enhanced ERK1/2 activation and augmented IL-6 production. Additionally, we revealed that IL-17A acts in concert with BCG-induced TNF-α to enhance the level of IL-6 synthesis. Taken together, our results suggest a significant role of IL-17A to serve as a modulator of cytokine expression in innate immune response during mycobacterial infection.

Abstract
OBJECTIVE To test the hypothesis that first re-treatment with infliximab, compared with intravenous immunoglobulin (IVIG), might improve outcomes in IVIG-resistant Kawasaki disease. STUDY DESIGN In a two-center retrospective review from January 2000 to March 2008, we compared duration of fever and coronary artery dimensions in patients with IVIG-resistance whose first re-treatment was with IVIG compared with infliximab given for fever ≥38.0°C beyond 36 hours after first IVIG completion. RESULTS Patients in the IVIG group (n = 86, 2 g/kg) and infliximab group (n = 20, 5 mg/kg) were similar in demographics, days of fever at diagnosis, and baseline coronary artery dimensions. Patients had similar coronary dimensions 6 weeks after diagnosis, both in univariate and multivariate analysis. The infliximab group had fewer days of fever (median 8 days versus10 days, P = .028), and in a multivariate analysis, the infliximab group had 1.2 fewer days of fever (P = .033). Patients who received infliximab had shorter lengths of hospitalization (median 5.5 days versus 6 days, P = .040). Treatment groups did not differ significantly in adverse events (0% versus 2.3%, P = 1.0). CONCLUSIONS In our retrospective study, patients with IVIG-resistant Kawasaki disease whose first re-treatment was with infliximab, compared with IVIG, had faster resolution of fever and fewer days of hospitalization. Coronary artery outcomes and adverse events were similar; the power of the study was limited.

Abstract
Most infections were in rheumatoid arthritis patients, and 44% were extrapulmonary or disseminated. Patients receiving anti–tumor necrosis factor-α (anti–TNF-α) therapy are at increased risk for tuberculosis and other granulomatous diseases, but little is known about illness caused by nontuberculous mycobacteria (NTM) in this setting. We reviewed the US Food and Drug Administration MedWatch database for reports of NTM disease in patients receiving anti–TNF-α therapy. Of 239 reports collected, 105 (44%) met NTM disease criteria. Median age was 62 years; the majority of patients (66, 65%) were female, and most (73, 70%) had rheumatoid arthritis. NTM infections were associated with infliximab (n = 73), etanercept (n = 25), and adalimumab (n = 7); most patients were taking prednisone (n = 68, 65%) or methotrexate (n = 58, 55%) concurrently. Mycobacteria avium (n = 52, 50%) was most commonly implicated, and 9 patients (9%) had died at the time their infections were reported. A high rate of extrapulmonary manifestations (n = 46, 44%) was also reported.
