As a systemic inflammatory disease, RA frequently affects not only synovial joints but also various extra-articular organs. These extra-articular manifestations (EAMs) are the most seri- ous predisposing factor for morbidity and mortality of RA patients. According to recent epide- miological studies, these EAMs are decreasing with the introduction of novel therapeutics, which would explain the improvement in prognosis. However, pulmonary involvements are an exception; they are becoming more and more serious and now are the major obstacles to the successful treatment of RA. In the prebiologics era, lung diseases caused serious problems in the management of RA as well. As shown in a large-scale cohort study conducted in Japan, they were the major cause of death of RA patients, together with malignancy. Lung diseases comprise infection, interstitial lung disease (ILD), and drug-induced pneumonia. With the introduction of novel DMARDs in the 2000s, severe pulmonary infections and drug-induced lung disease, along with exacerbations of preexisting ILD, began to occur with considerable frequency as adverse events of this therapy. A Japanese cohort study conducted recently reported that among RA patients undergoing biologics therapy, nearly 50% of the fatalities were attributable to lung diseases such as respi- ratory infections and ILD. This means that one of the most vital challenges in the current treat- ment of RA is the control of lung complications. The risk factors for such severe lung complications under the novel DMARD treatments have been enthusiastically screened and surveyed by many investigators. However, treatment strategies to address such complications have not been established in a sufficient manner. How should we confront these situations? Should patients with risk factors for such com- plications be excluded from beneficial treatment in this novel era? What should we do to diag- nose and treat each lung complication, sometimes in slowly progressive disease and sometimes in acutely developing illness? Except for tuberculosis, no practical guidelines have been for- mulated so far. In this book, we aim to answer these questions at the best level possible, on the basis of knowledge obtained from our recent investigations along with the current best evi- dence available. First, we clarify the pathogenesis and clinical implications of the lung diseases directly associated with RA (pulmonary EAMs), including airway diseases and ILD, from various aspects: clinical, radiological, and pathological. We emphasize the importance of airway disease, as one of the major risk factors of infec- tions in RA patients. Also, we show that it can ultimately progress to respiratory failure due to obstruction of the peripheral airways. A new pathological classification of obliterative bronchi- olitis is also presented. We also introduce a new insight into the pathogenesis of honeycombing seen in RA-ILD, the so-called UIP (usual interstitial pneumonia) type. We clarify that this cystic structural v vi Preface derangement is caused by persistent inflammatory destruction derived from RA in the periph- eral airways. From this insight, a possible treatment strategy is proposed against the progres- sion of RA-ILD. For ILD itself, clinical, radiological, and pathological problems are discussed, with a few of our original insights inserted among the established knowledge. Lastly, we discuss the diagnosis and treatment of lung infections and their cognate disor- ders, including organizing pneumonia and acute diffuse lung disease along with Pneumocystis pneumonia and drug-induced pneumonia. Here, we propose specific and practical procedures to handle these complicated conditions. We believe that the discussions presented here, which contain many of our new ideas and concepts, will be useful and beneficial for rheumatologists, pneumologists, and radiologists confronted with this vital clinical challenge, the diagnosis and treatment of lung diseases asso- ciated with RA.

In the 2000s, numerous novel antirheumatic agents, called biological disease-modifying antirheu- matic drugs (bDMARDs) as well as methotrexate, have becom available worldwide. These developments in treatment have resulted in RA remission or low disease activity in greater than 50% of RA patients. This recent progress has allowed RA patients attain improved physical function and prognosis. However, treatment-related events, such as infections, have occurred and occasionally caused severe or fatal outcomes in RA patients. Thus, clinicians must pay attention to complications during treatment with corticosteroids and/or DMARDs, especially bDMARDs. Approximately 50% of the causes of death in RA patients treated with bDMARDs involve respiratory disease, including pneumonia and interstitial lung disease. Therefore, clini- cians should manage these pulmonary complications promptly. In this book, we will describe the current status of knowledge about lung disease in RA and would suggest the best form of management of lung disease in RA patients for clinicians, including general practitioners, rheu- matologists, respirologists, radiologists, and pathologists. We hope that this book will prove helpful to all types of medical staff and clinicians who take care of RA patients.
