22096729 Bilateral recurrent wrist flexor tenosynovitis and rice body formation in a patient with s 2011 INTRODUCTION: Rice body formation has been traditionally observed in the joint and tendon sheaths of patients with tuberculosis. Few case reports exist that describe rice body formation in patients with rheumatoid arthritis. We describe a case report of bilateral recurrent wrist flexor tenosynovitis with rice body formation in a patient with sero-negative rheumatoid arthritis. PRESENTATION OF CASE: This case report describes a 72 year old lady presenting with severe bilateral, flexor tenosynovitis of the wrists. Ultrasonography revealed significant echogenic fluid on the palmer aspect of wrist joint surrounding flexor tendons with intact neurovascular bundles and no bony erosion. Laboratory tests demonstrated elevated erythrocyte sedimentation rate (50 mm/h) and negative rheumatoid factor. A sequential subtotal flexor tenosynovectomy was carried out with decompression of the carpal tunnel. During the operation, multiple rice bodies among the flexor tendons with adherent synovitis were found. Histology revealed disrupted synovial tissue containing several areas of fibrinoid necrosis, bounded by a layer of vaguely pallisaded histiocytes but no epitheloid granulomata or germinal centre. A revision surgery with debulking of the fibro-osseous canal was undertaken following recurrence. The patient presently has complete resolution of symptoms at one year follow-up. DISCUSSION: The combined clinical, laboratory, ultrasound and histology findings of the patient indicated that the cause of the rice body formation was due to a sero-negative arthritis rather than tuberculosis. CONCLUSION: Rice body formation can be caused by sero-negative arthritis. Bilateral wrist flexor tensosynovitis can recur within five months of a previous synovectomy in a patient with sero-negative arthritis.
31644159 Tumor Necrosis Factor Antagonists. 2012 Tumor necrosis factor (TNF) alpha is a bioactive cytokine that is an important component of the inflammatory and pain pathways. Inhibition of TNF can decrease the inflammatory response, and this approach has been used in therapy of autoimmune conditions, most effectively in inflammatory bowel disease (IBD), rheumatoid arthritis, juvenile idiopathic arthritis (also known as juvenile rheumatoid arthritis), psoriasis, psoriatic arthritis and ankylosing spondylitis. Five anti-TNF antagonists have been developed and introduced into clinical medicine: a mouse-human chimeric monoclonal antibody to TNF (infliximab), two human monoclonal antibodies to TNF (adalimumab and golimumab), a humanized Fab fragment of anti-TNF linked to polyethylene glycol (certolizumab), and a soluble recombinant form of the TNF cellular receptor (etanercept) which, on binding, blocks the activity of TNF. These TNF antagonists have potent activity in several autoimmune diseases marked by excessive production of this proinflammatory cytokine. All five of these agents are approved for use in rheumatoid arthritis and are considered “disease modifying anti-rheumatic drugs” (DMARDs), having been shown to decrease pain, improve function, and ameliorate progressive joint damage in rheumatoid arthritis. The monoclonal antibodies to TNF have also been shown to be effective in psoriatic arthritis, ankylosing spondylitis and inflammatory bowel disease. The five agents rarely cause serum aminotransferase elevations, but have been linked to rare instances of clinically apparent, acute liver injury which often resembles autoimmune hepatitis and can be severe or require corticosteroid therapy. TNF antagonists are also immunosuppressive and can lead to reactivation of latent infections such as tuberculosis and hepatitis B. Severe and even fatal instances of reactivation of hepatitis B have been linked to several anti-TNF agents, and routine screening for HBsAg before starting therapy with these agents is recommended. Patients with HBsAg should receive prophylaxis with an oral antiviral agent during therapy with one of the TNF antagonists. Among the TNF antagonists, infliximab has been most frequently and etanercept least frequently linked to liver injury, including asymptomatic serum aminotransferase elevations, induction of clinically apparent autoimmune hepatitis, and reactivation of hepatitis B. However, infliximab has been most extensively used and studied than the other anti-TNF monoclonal antibodies, and liver injury due to these agents is probably class specific. For these reasons, all five of these agents should be considered potentially hepatotoxic, etanercept perhaps less so that the others. Drug Class: Antirheumatic Agents; Gastrointestinal Agents; Psoriasis Agents
27790010 The role of adalimumab in rheumatic and autoimmune disorders: comparison with other biolog 2012 Adalimumab (ADA) is a biologic medication that dampens inflammatory pathways by binding to the cytokine tumor necrosis factor alpha. The US Food and Drug Administration has approved ADA as a medication for use in rheumatoid arthritis, psoriatic arthritis, ankylosing spondylitis, Crohn's disease, psoriasis, and juvenile idiopathic arthritis. This year marks 10 years of clinical experience with ADA. Long-term extension studies of some of the initial clinical trials, as well as data from large patient registries, are demonstrating ongoing benefit for responders. Potential side effects such as increased risk of infection, lymphoma, congestive heart failure, and demyelination continue to be examined, as the available data are not unanimous in showing an increase in incidence. In balancing both the advantages and the disadvantages of using ADA, the drug's overall effectiveness and its availability for use in patients with hepatic or renal comorbidities are weighed against the high cost. ADA is expected to have a leading role in the treatment of rheumatoid arthritis and other inflammatory conditions for years to come. Future studies will need to address the optimal sequence of disease-modifying antirheumatic drugs and biologics to use, combinations of disease-modifying antirheumatic drugs and biologics, and head-to-head comparisons of biologics in clinical trials. For those who go into clinical remission on an anti-tumor necrosis factor medication, unanswered questions remain about identifying the patients who can maintain the remission off all drugs, or at least off injected medication. Given the cost of biologic drugs, even studies that increase the interval between drug doses in well-controlled patients could provide financial benefits.
24648915 TNF inhibitor therapy for rheumatoid arthritis. 2013 Mar Immunotherapy has markedly improved treatment outcomes in rheumatoid arthritis (RA). Tumor necrosis factor (TNF)-α antagonists, such as infliximab (IFX), etanercept (ETN), adalimumab (ADA), golimumab (GOLI) and certolizumab pegol (CZP) have been widely used for the treatment of RA. IFX provides significant, clinically relevant improvement in physical function and the quality of life, inhibits progressive joint damage and sustains improvement in the signs and symptoms of patients with RA. ETN is effective and safe for patients with RA. Combination therapy with ETN plus methotrexate (MTX) reduces disease activity, decreases total joint score progression, slows the pace of joint destruction and improves function more effectively compared to any of the monotherapies. ADA with or without MTX also relieves the signs and symptoms of RA. CZP and GOLI expand the therapeutic schedule for patients with RA. The TNF-α inhibitors have similar efficacy, but distinct clinical pharmacokinetic and -dynamic properties. The common adverse events of these TNF-α antagonists include adverse reactions, infections and injection-site reaction. Additionally, these adverse events are mostly mild or moderate and their incidence is low. Certain patients exhibit a lack of response to anti-TNF-α therapies. Some patients may discontinue the initial drug and switch to a second anti-TNF-α agent. The shortage of clinical response to one agent may not predict deficiency of response to another. This review mainly addresses the latest developments of these biological agents in the treatment of RA.
22582103 Cost-effectiveness modelling of sequential biologic strategies for the treatment of modera 2012 OBJECTIVE: The main objective was to compare the cost-effectiveness of therapeutic options in moderate or severe rheumatoid arthritis (RA) when a clinical response to a first TNF-blocker, either etanercept (ETA), adalimumab (ADA), or infliximab (INF), is insufficient. METHODS: Effectiveness criteria were defined as remission (RS), low disease activity (LDAS), and moderate to high disease activity (MHDAS). Cost-effectiveness was derived as cost per day in RS and in LDAS using simulation modelling to assess six sequential biologic strategies over 2 years. Each sequential treatment strategy was composed of three biologic agents and included a first anti-TNF agent, ETA, ADA or INF, followed by either abatacept (ABA) or rituximab (RTX) as a second therapeutic option in case of an insufficient response, followed by another anti-TNF agent in case of further insufficient response. RESULTS: Over two years and taking into account biologic costs, the following estimated mean costs per day in RS and LDAS were respectively of €829 and €428 for the biologic sequence composed of ADA-ABA-ETA, €1292 and €516 for the sequence ADA-RTX-ETA, €829 and €429 for the sequence ETA-ABA-ADA, €1292 and €517 for the sequence ETARTX- ADA, €840 and €434 for the sequence INF-ABA-ETA, and €1309 and €523 for the sequence INF-RTX-ETA. CONCLUSION: The treatment sequences including ABA as the second biologic option appear more cost-effective than those including RTX in a patients with moderate to severe RA and an insufficient response to a first anti-TNF agent.
25737715 Effect of tumor necrosis factor inhibitors on rheumatoid arthritis-induced peripheral neur 2012 Apr 15 In this historical cohort study, 236 patients with primary rheumatoid arthritis were treated with the tumor necrosis factor inhibitors, etanercept or infliximab (n = 80), or by conventional methods (n = 156). Results revealed that 11 patients developed varying types of peripheral neuropathy at 1-2 years post-treatment (mean 16 months). The incidence of peripheral neuropathy in the tumor necrosis factor inhibitors treatment group was 8.8% (7/80), which was significantly higher than the conventional treatment group (2.6%; 4/156). The relative risk of developing peripheral neuropathy in the tumor necrosis factor inhibitors treatment group was 3.41 (95% confidence interval: 1.03-11.31). Comparison of the tumor necrosis factor inhibitors revealed that etanercept and infliximab had no significant difference in terms of inducing peripheral neuropathy. Experimental findings indicate that tumor necrosis factor inhibitors may increase the risk of peripheral neuropathy.
21385548 Adult onset Still's disease: review of 41 cases. 2011 Mar OBJECTIVES: To describe the clinical, laboratory and radiological features, treatment and prognosis of patients with adult onset Still's disease (AOSD). METHODS: Specific clinical features were retrospectively recorded in 41 patients fulfilling the Yamaguchi criteria. Patients were reviewed in two academic hospitals with a referral area of 700,000-1,000,000 inhabitants. Laboratory tests including haemogram, ferritin, biochemistry and autoimmunity were reviewed. Radiological studies, treatment and ACR functional class were determined. RESULTS: Forty-one patients with AOSD were identified, 25 of whom were female. Mean age at diagnosis: 38.19 years (range 17-68). Feverish polyarthritis was the most common clinical presentation. Acute phase reactants were invariably high in all patients. Serum ferritin levels were elevated in 86% of patients. Anti-cyclic citrullinated peptide antibodies (anti-CCP antibodies) were negative in all patients except one. The course of the disease was monocyclic in 44% of the patients, polycyclic in 26%, and chronic articular in 30%. ACR class was as follows: 29 (72.5%) class I, 7 (17.5%) class II, 2 (5%) class III and 2 (5%) class IV. As for the treatment received, aspirin or NSAIDs controlled the disease in eight patients (19.5%) and high-dose corticosteroids (0.5-1 mg/kg/day) in 32 (78%). Almost half of the patients (49%) required an additional diseasemodifying agent, usually methotrexate. Finally, in seven of them (17%) a biological treatment with TNF-α or specially anti-IL-1 had to be added to control the disease. CONCLUSIONS: The clinical and laboratory findings were similar to previous studies. Anti-CCP antibodies were almost always negative. A monocyclic course was associated with a good prognosis. Most of the patients were in ACR functional class I and II. Biological agents were required in 7 patients (17%).
22089074 [Acute miopericarditis as the presenting feature of adult-onset Still's disease]. 2012 Jan Adult Still's disease (ASD) was described by George Still in 1896. ASD is a rare inflammatory disorder, of unknown etiology, whose clinical manifestations are manifold. Diagnosis requires high clinical suspicion and exclusion of different etiologies. We report the case of a 20 year old male with fever, arthritis, dyspnea and chest pain. Laboratory findings showed increased levels of cardiac enzymes, and a pleuropericardic effusion was detected in imaging tests, both of them showing myopericarditis. Corticosteroid treatment was started with initial improvement, although the addition of methotrexate was necessary in the following months.
23326703 Dyspnea caused by atlantoaxial subluxation in a patient with rheumatoid arthritis. 2012 Atlantoaxial subluxation is a well-known but poorly recognized disease in rheumatoid patients. We report a patient with rheumatoid arthritis whose chief complaint was dyspnea on arrival to the emergency department (ED). After further investigation, spinal cord compression caused by atlantoaxial subluxation was diagnosed. This is an uncommon but important case that ED physicians should be aware of.
21861931 Tyrosine kinases in rheumatoid arthritis. 2011 Aug 24 Rheumatoid arthritis (RA) is an inflammatory, polyarticular joint disease. A number of cellular responses are involved in the pathogenesis of rheumatoid arthritis, including activation of inflammatory cells and cytokine expression. The cellular responses involved in each of these processes depends on the specific signaling pathways that are activated; many of which include protein tyrosine kinases. These pathways include the mitogen-activated protein kinase pathway, Janus kinases/signal transducers and activators transcription pathway, spleen tyrosine kinase signaling, and the nuclear factor κ-light-chain-enhancer of activated B cells pathway. Many drugs are in development to target tyrosine kinases for the treatment of RA. Based on the number of recently published studies, this manuscript reviews the role of tyrosine kinases in the pathogenesis of RA and the potential role of kinase inhibitors as new therapeutic strategies of RA.
22405136 Pneumococcal polyarticular septic arthritis after a single infusion of infliximab in a rhe 2012 Mar 9 INTRODUCTION: We present a case of Streptococcus pneumoniae polyarticular septic arthritis in a patient with rheumatoid arthritis receiving a single infusion of infliximab. CASE PRESENTATION: A 38-year-old Japanese man with a 5-year history of seronegative rheumatoid arthritis had previously received sulphasalazine and methotrexate therapies and was on regular low-dose prednisolone therapy. Despite these treatments, his disease activity remained high and infliximab was introduced in addition to methotrexate, prednisolone, and folic acid. However, he was admitted to hospital with a fever of 40.6°C, chills, and polyarthralgia eight days after the first infusion of infliximab. His joints were swollen, painful, and warm. Laboratory data showed marked acute inflammation. He was diagnosed with bacterial septic polyarthritis, and emergency surgical joint lavage and drainage was performed at the knees along with needle aspiration and lavage of the ankles and right wrist. He was then given intravenous antibiotic therapy for 31 days. He made a good recovery and was discharged on day 37. CONCLUSIONS: We believe this is the first reported case of severe pneumococcal septic arthritis requiring hospitalization in a patient treated with infliximab. S. pneumonia is now a well-recognized but uncommon cause of polyarticular septic arthritis that can lead to cessation of therapy, as in our patient's case.
24024009 Rheumatoid Arthritis: Early diagnosis and treatment outcomes. 2011 Winter Rheumatoid arthritis (RA) is an inflammatory progressive disease which in the absence of appropriate treatment can lead to joint destruction and disability. Prognosis of RA may be predicted based on the presence of some clinical and laboratory evidences. New criteria for classification of RA provide opportunity for earlier treatment. Initiation of treatment particularly by combination of DMARDs concurrent with short duration of corticosteroid is expected to prevent progressive course and even change the natural course of RA. At present any patients with clinical synovitis in at least one joint may have definite RA, requiring agressive treatment.
22566902 A New-Age for Biologic Therapies: Long-Term Drug-Free Therapy with BiP? 2012 Heat shock proteins (HSPs) and other members of the much broader stress protein family have been shown to play important roles in coordinating multiple phases of immunological reactions; from facilitating immunological recognition, to promoting and regulating immunological responses and finally augmenting the resolution of inflammation and return to immunological homeostasis. In this review, we consider the challenges facing the stress protein field as we enter 2012; in particular we consider the role that HSPs and stress proteins may play in the initiation and termination of immunological responses. Special attention is afforded to the resolution-associated molecular pattern, binding immunoglobulin protein (BiP, also known as glucose regulated protein-78). We review the evidence that resolution-promoting proteins such as BiP may herald a new generation of biologics for inflammatory disease and reflect on the challenges of achieving clinical remission in rheumatoid arthritis with novel therapeutics and correlating clinical remission with immunological parameters of resolution of inflammation.
22216410 Dynamic Contrast Enhanced MRI Can Monitor the Very Early Inflammatory Treatment Response u 2011 Dynamic contrast-enhanced MRI in inflammatory arthritis, especially in conjunction with computer-aided analysis using appropriate dedicated software, seems to be a highly sensitive tool for monitoring the early inflammatory treatment response in patients with rheumatoid arthritis. This paper gives a review of the current knowledge of the emerging technique. The potential of the technique is demonstrated and discussed in the context of a case report following the early effect of an intra-articular steroid injection in a patient with rheumatoid arthritis flare in the knee.
22563239 Survey of a community-based infusion program for Australian patients with rheumatoid arthr 2012 BACKGROUND: Tocilizumab is an effective therapy for patients with moderate to severe rheumatoid arthritis that is administered by infusion over one hour every 4 weeks. The community-based infusion (ACTiv) program was introduced to Australia in August 2010 to provide accessible and convenient treatment for patients with rheumatoid arthritis who require tocilizumab. The primary objectives of this study were to determine the characteristics of patients in the ACTiv program, patient satisfaction, and patient-perceived benefits and concerns with the ACTiv program, and drivers of patient satisfaction and patient-perceived benefits and concerns. METHODS: A voluntary self-administered survey was given to all 608 patients in the ACTiv program between January 27, 2011 and March 31, 2011. RESULTS: A total of 351 surveys were returned completed, giving a response rate of 58% (351/608). Most patients in the ACTiv program were women aged 40-64 years, with a mean disease duration of 13.7 years and moderate disability, who had been in the ACTiv program for ≥5 months. Most patients (88%, 302/342) were either very satisfied or satisfied with the ACTiv program and believed that they were very unlikely or somewhat unlikely to switch from the ACTiv program (64%, 214/335). The most important benefit was the reassurance of receiving treatment from a trained nurse in a professional medical environment (33%, 102/309). The most important concern was the fear of side effects (48%, 134/280). The main drivers of patient satisfaction and patient-perceived benefits and concerns of patients were health profile, previous medication experience, and length of treatment time in the program. CONCLUSION: The ACTiv program is used by patients of various ages, family life situations, and locations. Patient satisfaction with the program is high, which enables patients to benefit from long-term use of tocilizumab.
22358143 Dominant vertebral artery injury during posterior atlantoaxial transarticular screw fixati 2012 Many authors have reported on iatrogenic vertebral artery (VA) injury, but, to our knowledge, this is the first report of a dominant VA injury with compensatory blood flow from the hypoplastic VA. A 23-year-old woman with juvenile rheumatoid arthritis and atlantoaxial subluxation sustained injury to her dominant VA after occipitocervical fusion using transarticular screws. This did not result in lethal consequences due to compensation from her hypoplastic contralateral VA. Postoperative angiography, however, illustrated occlusion of the dominant left side, while the hypoplastic VA of the right side was enlarged. The patient experienced vertigo and loss of consciousness several times during rehabilitation. At the 4-year follow-up exam, bony fusion was observed, with no neurological deficits or correction loss. She had had no episodes of unconsciousness and no recurrence of any symptoms over the previous 3 years.
21897637 The efficacy of Ayurvedic treatment for rheumatoid arthritis: Cross-sectional experiential 2011 Jan CONTEXT: Allopathic and Ayurvedic physicians collaborated on a study of traditional medicine, which was sponsored by the World Health Organization. AIMS: The aim of the study was to test the efficacy and safety of Ayurvedic treatment for rheumatoid arthritis (RA). SETTINGS AND DESIGN: This study was conducted at the Ayurvedic Trust, Coimbatore, India. MATERIALS AND METHODS: In this unique study of classical Ayurvedic treatment for RA, allopathic physicians enrolled a total of 290 patients with a confirmed diagnosis of RA over a 7-year period, and once every 6 weeks evaluated Ayurvedic treatment outcomes on the basis of American Rheumatism Association criteria: grip strength, walking time, number of swollen and painful joints, joint count, functional class, erythrocyte sedimentation rate, and rheumatoid factor. Ayurvedic physicians administered individualized treatment, closely adhering to principles set forth in classical Ayurvedic texts. The duration of treatment varied from 1 to 6 months. STATISTICAL ANALYSIS USED: Due to limitations in computer technology in the 1970s, the data were not computerized. Therefore, data for 12 months at a time were analyzed, using repeated measures t-test. Measures of central tendency (means) and probability values were reported. Results from the patients enrolled and discharged at the end of the first year of the study (N = 33) are presented in this paper. RESULTS: There was statistically significant improvement in all parameters from admission to discharge. CONCLUSIONS: The results indicated that classical Ayurvedic treatment was effective in this first cohort of patients who completed treatment. Even patients with severe functional limitations showed significant improvement. Although there was no control group, the results are positive enough to warrant further study of classical Ayurvedic treatment for RA in controlled trials.
21915375 A systematic review of serum biomarkers anti-cyclic citrullinated Peptide and rheumatoid f 2011 This systematic review assesses the current status of anti-cyclic citrullinated peptide (anti-CCP) and rheumatoid factor (RF) tests in the diagnosis and prognosis of rheumatoid arthritis (RA). We reviewed publications on tests and biomarkers for early diagnosis of RA from English-language MEDLINE-indexed journals and non-MEDLINE-indexed sources. 85 publications were identified and reviewed, including 68 studies from MEDLINE and 17 non-MEDLINE sources. Anti-CCP2 assays provide improved sensitivity over anti-CCP assays and RF, but anti-CCP2 and RF assays in combination demonstrate a positive predictive value (PPV) nearing 100%, greater than the PPV of either of the tests alone. The combination also appears to be able to distinguish between patients whose disease course is expected to be more severe and both tests are incorporated in the 2010 ACR Rheumatoid Arthritis Classification Criteria. While the clinical value of anti-CCP tests has been established, differences in cut-off values, sensitivities and specificities exist between first-, second- and third-generation tests and harmonization efforts are under way. Anti-CCP and RF are clinically valuable biomarkers for the diagnosis and prognosis of RA patients. The combination of the two biomarkers in conjunction with other clinical measures is an important tool for the diagnosis and management of RA patients.
22859921 The role of RANK ligand/osteoprotegerin in rheumatoid arthritis. 2012 Aug In the complex system of bone remodeling, the receptor activator of nuclear factor κB ligand (RANKL)/osteoprotegerin (OPG) pathway is the coupling factor between bone formation and bone resorption. RANKL binds to the RANK receptor of pre-osteoclasts and mature osteoclasts and stimulates their activation and differentiation. The production of RANKL/OPG by osteoblasts is influenced by hormones, growth factors and cytokines, which each have a different effect on the production of RANKL and OPG. Ultimately, the balance between RANKL and OPG determines the degree of proliferation and activity of the osteoclasts. In rheumatoid arthritis (RA), bone erosions are the result of osteoclastic bone resorption at the sites of synovitis, where RANKL expression is also found. Furthermore, magnetic resonance imaging (MRI) bone edema in RA indicates the presence of active inflammation within bone and the presence of osteitis, which is also associated with the expression of RANKL. Bone loss has been documented in the cortical and trabecular bone in the joints of the hand of RA patients. Both synovitis and periarticular bone involvement (osteitis and bone loss) are essential components of RA: they occur early in the disease and both are predictive for the occurrence and progression of bone damage. RANKL knockout mice and mice treated with OPG did not develop focal bone loss, in spite of persistent joint inflammation. Inhibition of osteoclasts by denosumab, a humanized antibody that selectively binds RANKL, has revealed in patients with RA that the occurrence of erosions and periarticular bone loss can be halted, however without affecting synovial inflammation. This disconnect between inflammation and bone destruction opens new ways to separately focus treatment on inflammation and osteoclastogenesis for preventing and/or minimizing the connection between joints and subchondral bone and bone marrow.
27790009 Rheumatoid arthritis-associated interstitial lung disease. 2012 Rheumatoid arthritis (RA) is a systemic inflammatory disorder affecting 1% of the US population. Patients can have extra-articular manifestations of their disease and the lungs are commonly involved. RA can affect any compartment of the respiratory system and high resolution computed tomography (HRCT) of the lung is abnormal in over half of these patients. Interstitial lung disease is a dreaded complication of RA. It is more prevalent in smokers, males, and those with high antibody titers. The pathogenesis is unknown but data suggest an environmental insult in the setting of a genetic predisposition. Smoking may play a role in the pathogenesis of disease through citrullination of protein in the lung leading to the development of autoimmunity. Patients usually present in middle age with cough and dyspnea. Pulmonary function testing most commonly shows reduced diffusion capacity for carbon monoxide and HRCT reveals a combination of reticulation and ground glass abnormalities. The most common pattern on HRCT and histopathology is usual interstitial pneumonia (UIP), with nonspecific interstitial pneumonia seen less frequently. There are no large-scale well-controlled treatment trials. In severe or progressive cases, treatment usually consists of corticosteroids with or without a cytotoxic agent for 6 months or longer. RA interstitial lung disease is progressive; over half of patients show radiographic progression within 2 years. Patients with a UIP pattern on biopsy have a survival similar to idiopathic pulmonary fibrosis.
