Abstract
Inflammatory bowel disease can manifest in many extraintestinal organ systems. The most frequently involved extraintestinal locations include the mucocutaneous, hepatobiliary, and ocular organ systems. The respiratory tract is less commonly involved and is therefore frequently overlooked. Consequently, it is believed that involvement of the respiratory tract in patients with inflammatory bowel disease is underreported. The pathogenesis is thought to be multifactorial, involving the common embryologic origin shared by the respiratory and luminal digestive tract, molecular mimicry, and immunologic interactions leading to immune-complex deposition in affected tissue. The spectrum of manifestations of the respiratory tract related to inflammatory bowel disease is broad. It not only includes direct involvement of the respiratory tract (ie, airways, interstitium, and pleura) but also can result as a consequence of systemic involvement such as in thromboembolic events. In addition, it may also be related to other conditions that affect the respiratory tract such as sarcoidosis and alpha-1 antitrypsin deficiency. Though some conditions related to respiratory tract involvement might be subclinical, others may have life-threatening consequences. It is critical to approach patients with suspected inflammatory bowel disease-related respiratory tract involvement in concert with pulmonology, infectious diseases, and any other pertinent experts, as treatments may require a multidisciplinary overlap of measures. Therefore, it is of paramount importance for the clinician to be aware of the array of respiratory tract manifestations of patients with inflammatory bowel disease, in addition to the possible spectrum of therapeutic measures.

Abstract
Bronchiolitis obliterans organizing pneumonia (BOOP) is defined by buds of granulation tissue within lung distal airspaces. The diagnosis requires the histopathologic evidence of organizing pneumonia along with a suggestive clinical and radiographic pattern. This disorder is characterized by a good response to corticosteroids and an excellent prognosis. It can occur in association with a broad spectrum of clinical conditions or can be isolated, in this last case named cryptogenic organizing pneumonia. We searched for BOOP in patients with autoimmune rheumatic diseases (ARD) in the literature, and we found 32 well-documented cases. We reported here demographic features, manifestations, treatment and outcome of patients with BOOP associated with ARD. Notably, BOOP can be the presenting feature in some patients with ARD; thus, a close follow-up of patients with BOOP is recommended.

Antisynthetase antibody syndrome: case report and review of the literature. Clin Rheumatol 2013; 32:715-9. [PMID: 23423441 DOI: 10.1007/s10067-013-2207-5] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/14/2013] [Accepted: 01/30/2013] [Indexed: 11/28/2022]
Abstract
Antisynthetase antibody syndrome is a rare autoimmune disease that may present with variable systemic manifestations, mainly polymyositis, interstitial lung disease, skin lesions, and Raynaud's phenomenon. This diagnosis should always come to mind in patients that present with signs of myositis, dermatomyositis, or polymyositis associated with interstitial lung disease. On the following paper, we report the case of a 52-year-old man who presented with a 2-month history of asymmetric polyarthralgia, myalgia, weight loss of 8 kg, and progressive muscle weakness associated with dyspnea, orthopnea, and dysphonia. Further tests revealed myositis, interstitial pneumonia, and elevation of anti-Jo-1 antibodies. A diagnosis of antisynthetase antibody syndrome was made and the patient showed good response to treatment with corticoids and methotrexate. Finally, we present a short review of the literature.

Abstract
Autoantibodies to eight of the aminoacyl-transfer RNA synthetases-the most well-recognized of which is anti-histidyl (Jo-1)-have all been implicated in the pathogenesis of antisynthetase syndrome (AS). AS is characterized by varying degrees of interstitial lung disease, myositis, arthropathy, fever, Raynaud's phenomenon, and mechanic's hands, and the morbidity and mortality of the disease are usually linked to the pulmonary findings. The value of a lung biopsy in AS cannot be overemphasized, as it serves to describe the underlying etiology of the interstitial lung disease, guide therapy, and estimate prognosis. Muscle disease shares many clinical features of polymyositis, yet histologically, the inflammatory involvement resembles that of dermatomyositis. Because inflammatory arthritis mimics rheumatoid arthritis, AS should be considered in atypical cases. Corticosteroids are the mainstay of acute therapy, although treatment often requires immunosuppressant medications such as cyclophosphamide, azathioprine, mycophenolate mofetil, cyclosporine, tacrolimus, or rituximab.

Abstract
Only a few pathologic reports exist describing adult onset Still's disease (AOSD) with pulmonary involvement. We report this very rare case of AOSD complicated with cryptogenic organizing pneumonia (COP). A 32-year-old woman was referred with high spiking fever, salmon-pink rash in her arms and legs, and polyarthralgia. The laboratory data showed marked increases in white blood cell count, an erythrocyte sedimentation rate, and C reactive protein, ferritin, and liver dysfunction. All cultures remained negative, as were autoantibodies and rheumatoid factor. The patient was strongly suspected of AOSD according to specific diagnostic criteria. However, chest X ray disclosed an infiltrative shadow accompanied by air bronchogram in the upper lobe of the right lung and therapy with antibiotics was initiated. As the patient did not respond to antibiotics and a remittent fever of over 38°C, a flexible bronchoscopy was performed. Organizing pneumonia was diagnosed by transbronchial lung biopsy (TBLB) histology and radiologically, and the lesions were thought to be due to pulmonary involvement of AOSD. Therefore, she was diagnosed with AOSD complicated with COP. Oral treatment with prednisolone (30 mg/day) resulted in rapid disappearance of the infiltrative shadow. Symptoms and markers of inflammation also improved. Clinicians should be aware that COP can be a complication of AOSD.

Abstract
Bronchiolitis obliterans organizing pneumonia (BOOP) was first described in the early 1980s as a clinicopathologic syndrome characterized symptomatically by subacute or chronic respiratory illness and histopathologically by the presence of granulation tissue in the bronchiolar lumen, alveolar ducts and some alveoli, associated with a variable degree of interstitial and airspace infiltration by mononuclear cells and foamy macrophages. Persons of all ages can be affected. Dry cough and shortness of breath of 2 weeks to 2 months in duration usually characterizes BOOP. Symptoms persist despite antibiotic therapy. On imaging, air space consolidation can be indistinguishable from chronic eosinophilic pneumonia (CEP), interstitial pneumonitis (acute, nonspecific and usual interstitial pneumonitis, neoplasm, inflammation and infection). The definitive diagnosis is achieved by tissue biopsy. Patients with BOOP respond favorably to treatment with steroids.

Abstract
We report of a 46-year-old female patient with cryptogen organizing pneumonia preceding the rare SRP positive necrotising myositis without cardiac involvement and no sign of dysphagia. Myositis showed full regression without oral immune suppression but with extracorporeal treatment, performed as a combined therapy of plasmaexchange and immunoadsorption. After 33-month of treatment, anti-SRP antibodies were not detectable any more.

Abstract
A 55-year-old male presented a productive cough, haemoptysis, and intermittent fever for 2 weeks. He was diagnosed as having Behcet's disease (BD) with manifestations of recurrent oral ulcers, genital ulcers, erythema nodosum, a gastro/duodenal ulcer, colon ulcers, and folliculitis. After admission, a chest X-ray showed bilateral ill-defined patches. Subsequent chest computerized tomography revealed multiple patchy consolidations over the left and right lower lobes. Because of poor response to oxacillin antibiotic treatment, an open lung biopsy was arranged. Bronchiolitis obliterans organizing pneumonia (BOOP) was diagnosed. Methylprednisolone pulse therapy, followed by prednisolone and cyclophosphamide maintenance, was prescribed. The patient responded well, with clinical and radiological resolution. Early diagnosis with proper treatment is crucial in the management of this lethal pulmonary disease.

Abstract
BACKGROUND We highlight a chronic inflammatory disease we call 'hyper-IgG4 disease', which has many synonyms depending on the organ involved, the country of origin and the year of the report. It is characterized histologically by a lymphoplasmacytic inflammation with IgG4-positive cells and exuberant fibrosis, which leaves dense fibrosis on resolution. A typical example is idiopathic retroperitoneal fibrosis, but the initial report in 2001 was of sclerosing pancreatitis. METHODS We report an index case with fever and severe systemic disease. We have also reviewed the histology of 11 further patients with idiopathic retroperitoneal fibrosis for evidence of IgG4-expressing plasma cells, and examined a wide range of other inflammatory conditions and fibrotic diseases as organ-specific controls. We have reviewed the published literature for disease associations with idiopathic, systemic fibrosing conditions and the synonyms: pseudotumour, myofibroblastic tumour, plasma cell granuloma, systemic fibrosis, xanthofibrogranulomatosis, and multifocal fibrosclerosis. RESULTS Histology from all 12 patients showed, to varying degrees, fibrosis, intense inflammatory cell infiltration with lymphocytes, plasma cells, scattered neutrophils, and sometimes eosinophilic aggregates, with venulitis and obliterative arteritis. The majority of lymphocytes were T cells that expressed CD8 and CD4, with scattered B-cell-rich small lymphoid follicles. In all cases, there was a significant increase in IgG4-positive plasma cells compared with controls. In two cases, biopsies before and after steroid treatment were available, and only scattered plasma cells were seen after treatment, none of them expressing IgG4. Review of the literature shows that although pathology commonly appears confined to one organ, patients can have systemic symptoms and fever. In the active period, there is an acute phase response with a high serum concentration of IgG, and during this phase, there is a rapid clinical response to glucocorticoid steroid treatment. CONCLUSION We believe that hyper-IgG4 disease is an important condition to recognise, as the diagnosis can be readily verified and the outcome with treatment is very good.

Abstract
In this comprehensive review, two very closely related interstitial pneumonias are discussed: the cryptogenic form of organizing pneumonia (COP); and secondary forms of organizing pneumonia (OP), which occur in association with identifiable medical conditions. Some newer and lesser known of these associated conditions are described, most importantly post-radiation OP.Rapidly progressive, corticosteroid-resistant and poor prognostic forms of OP have been described. These types purportedly occur more frequently in secondary OP. However, OPs frequently coexist with other interstitial pneumonias, especially when associated with connective tissue diseases. Therefore, tissue sampling error or an incorrect morphologic diagnosis can be the basis for the occurrence of clinically aggressive OPs. By using the 2002 American Thoracic Society/European Respiratory Society diagnostic criteria, some pre-2002 cases reported as OP would be re-classified today.Although COP is considered to have a good prognosis and to be corticosteroid responsive, approximately 70% of patients, treated with corticosteroids, relapse even during initial treatment. Multiple and late relapses occur in about one-third of the patients. We performed a meta-analysis of second-line treatment options for corticosteroid-refractory forms of OP. Three alternative nonsteroid agents - cyclophosphamide, azathioprine, and cyclosporin - have been used in combination with corticosteroids. On careful review, in a number of cases reported as secondary OP, other histologic interstitial patterns besides OP were described. The need for second-line therapy in these patients might have been dictated by the non-organizing pneumonic component. Most of the scant number of reports come from outside the US. World experience with these is limited, but good clinical outcomes have been noted, even in patients with interstitial patterns in addition to OP.The initiation of the OP tissue response in the bronchiolar and sub-bronchiolar location may be due to the presence of bronchiolar-associated lymphoid tissue found at the bifurcations of the bronchioles. Inhaled antigens stimulate granulocyte colony stimulating factor-mediated airway inflammation, followed later by CD44-mediated clearance. Repair requires intrabronchiolar formation of granulation tissue and a favorable ratio of matrix metalloproteinase to tissue inhibitors of metalloproteinase (MMP : TIMP) within the stroma. This reparative milieu allows extracellular matrix degradation and re-synthesis to occur. MMP-expressing fibroblasts then phagocytose the collagen fibrils and microfibrils produced earlier in repair, reversing the initial fibrosis.

Abstract
PURPOSE OF REVIEW Basic information as well as more recent concepts regarding cryptogenic organizing pneumonia and secondary forms of the disease. RECENT FINDINGS More recently described and less well recognized illnesses associated with organizing pneumonia, such as organizing pneumonia associated with radiation, are enumerated. In vitro studies from separate laboratories are integrated to create a proposed model of the pathogenesis and repair mechanisms that occur in organizing pneumonias. Using current criteria, we note other interstitial lung processes, in addition to organizing pneumonia, are present in some earlier reports. SUMMARY Cryptogenic organizing pneumonia has been reported to respond to corticosteroids with clinico-radiographic resolution in 70-80% of cases. Treatment duration is lengthy, and despite this, recurrences and late recurrences are common. Rapidly progressive, steroid resistant and poor prognostic forms of organizing pneumonia have been described and have been reported more frequently with secondary organizing pneumonia. Since other histologic interstitial patterns often coexist with organizing pneumonia, tissue sampling error or an incorrect morphologic diagnosis can be the reason for aggressive clinical behavior. Steroid nonresponsive patients have been treated with secondary non-steroidal agents. Good clinical outcomes have been reported. Inhaled antigens stimulate GM-CSF-mediated airway inflammation in organizing pneumonia. Repair requires the following: granulation tissue, upon which re-epithelialization occurs; a favorable stromal ratio of matrix metalloproteinase to tissue inhibitors of metalloproteinase; concurrent resolution of inflammation; and stromal fibroblast ingestion of collagen produced earlier in repair, reversing the initial fibrosis.

Abstract
In 1996 36-year-old man was admitted into our hospital because of polyarthralgia, skin eruptions followed by multiple cutaneous ulcers, dry cough and elevation of C-reactive protein level. The finding of skin biopsy from left elbow was vasculitis. Chest CT showed linear interstitial shadow at bilateral dorsalis lungs. Transbronchial lung biopsy (TBLB) revealed marked infiltration of inflammatory cells in the bronchial walls and peripheral alveoli. In addition, eosinophils were not in branchoalveolar lavage (BAL) fluid. Moreover, video-assisted thoracic surgery (VATS) revealed organizing fibroblastic polyp and bronchiolitis obliterans at terminal bronchiole. We diagnosed his pneumonia as bronchiolitis obliterans organizing pneumonia (BOOP). Administration of oral prednisolone (40 mg/day) was begun and he experienced diminished BOOP and other clinical manifestations. Three years later he developed dry cough, dyspnea and digital ulcers again. Arterial blood gas analysis revealed marked hypoxemia and laboratory studies showed LDH (377 IU/ml) and CRP (8.27 mg/dl) levels were elevated. Chest CT pointed out an exacerbation of BOOP. Treatment with intravenous pulses methylprednisolone and oral prednisolone (60 mg/day) resulted in marked improvement of the clinical manifestations. We describe a rare case of vasculitis associated with BOOP.

Abstract
Dermatomyositis is one of the idiopathic inflammatory myopathies with characteristic cutaneous manifestations including the heliotrope rash, Gottron's papules, cuticular changes including periungual telangiectasia, a photodistributed erythema or poikiloderma, and a scaly alopecia. Dermatomyositis has been linked to cancer, particularly ovarian cancer. Cancer-associated disease is more commonly found in older patients, and when present, is associated with a poor prognosis. A childhood form of the disease exists and is frequently complicated by the development of calcinosis. Dermatomyositis is a systemic disorder and whereas the skin and muscles are the most commonly affected organs, patients may have arthralgias, arthritis, oesophageal disease, or cardiopulmonary dysfunction. Recently described serological abnormalities, known as myositis-specific antibodies, add credence to the notion that this disorder is distinct from all other collagen-vascular diseases, and may lead to important discoveries about the pathogenesis of the inflammatory myopathies, which are not currently of practical use in the clinic or office. Management of the patient with myositis usually includes systemic corticosteroids with or without an immunosuppressive agent. Cutaneous disease is more difficult to manage, but antimalarials, methotrexate, and intravenous immunoglobulin are effective in small, often open-label, studies.
