Abstract
BACKGROUND Interstitial lung diseases (ILDs) are a group of disorders characterised by progressive lung function decline. Stabilisation of lung function under intermittent i.v. cyclophosphamide was shown in patients suffering from systemic sclerosis, yet data in ILD patients are scarce. OBJECTIVES To retrospectively evaluate the usefulness of cyclophosphamide pulse therapy in ILD. METHODS We retrospectively analysed all patients who received i.v. cyclophosphamide in our centre from 2002 to 2012. Lung function, survival status, and bronchoalveolar lavage cytology were recorded during a follow-up period of 18 months. RESULTS Twenty-six patients with idiopathic pulmonary fibrosis, 6 with lymphocytic interstitial pneumonia (LIP), 8 with idiopathic non-specific interstitial pneumonia (NSIP), 7 with rheumatoid arthritis-associated ILD, and 7 with perinuclear anti-neutrophil cytoplasmic antibody-positive ILD (pANCA+ ILD) were included. Patients with LIP and NSIP had the best survival outcome, those with pANCA+ ILD the worst. In the total cohort, we found a significantly higher total lung capacity decline in the year before treatment compared to the year after treatment. CONCLUSIONS This retrospective analysis of cyclophosphamide treatment shows a stabilisation of lung function in most patients with fibrotic ILDs, yet prospective studies in clearly defined diagnoses are urgently needed.

Abstract
The lungs are frequently involved in Connective Tissue Diseases (CTDs). Interstitial lung disease (ILD) is one of the most common pleuropulmonary manifestations that affects prognosis significantly. In practice, rheumatologists and other physicians tend to underestimate the impact of CTD-ILDs and diagnose respiratory impairment when it has reached an irreversible fibrotic stage. Early investigation, through clinical evidence, imaging and - in certain cases - lung biopsy, is therefore warranted in order to detect a possible ILD at a reversible initial inflammatory stage. In this review, we focus on lung injury during CTDs, with particular attention to ILDs, and examine their prevalence, clinical manifestations and histological patterns, as well as therapeutic approaches and known complications till date. Although several therapeutic agents have been approved, the best treatment is still not certain and additional trials are required, which demand more knowledge of pulmonary involvement in CTDs. Our central aim is therefore to document the impact that lung damage has on CTDs. We will mainly focus on Rheumatoid Arthritis (RA), which - unlike other rheumatic disorders - resembles Idiopathic Pulmonary Fibrosis (IPF) in numerous aspects.

Abstract
OBJECTIVES Immunosuppressive pharmacologic agents prescribed to patients with diffuse interstitial and inflammatory lung disease and lung transplant recipients are associated with potential risks for adverse reactions. Strategies for minimizing such risks include administering these drugs according to established, safe protocols; monitoring to detect manifestations of toxicity; and patient education. Hence, an evidence-based guideline for physicians can improve safety and optimize the likelihood of a successful outcome. To maximize the likelihood that these agents will be used safely, the American College of Chest Physicians established a committee to examine the clinical evidence for the administration and monitoring of immunosuppressive drugs (with the exception of corticosteroids) to identify associated toxicities associated with each drug and appropriate protocols for monitoring these agents. METHODS Committee members developed and refined a series of questions about toxicities of immunosuppressives and current approaches to administration and monitoring. A systematic review was carried out by the American College of Chest Physicians. Committee members were supplied with this information and created this evidence-based guideline. CONCLUSIONS It is hoped that these guidelines will improve patient safety when immunosuppressive drugs are given to lung transplant recipients and to patients with diffuse interstitial lung disease.

Abstract
Idiopathic pulmonary fibrosis (IPF) is a chronic condition of unknown etiology with an unfavorable outcome from progressively deteriorating respiratory function, leading ultimately to death from respiratory failure. It is characterized by sequential acute lung injury resulting in progressive fixed tissue fibrosis, architectural distortion and loss of function. An excess of profibrotic cytokines and/or a deficiency in antifibrotic cytokines have been implicated in the pathological process as has excessive oxidation. IPF is distinguished from other forms of diffuse pulmonary fibrosis by the presence of the specific histological pattern of usual interstitial pneumonitis. Oral corticosteroids are the usual treatment, but objective response rates are poor and good quality studies do not exist. Other therapies either alone or in combination with corticosteroids are widely used, including azathioprine, colchicine, cyclophosphamide and penicillamine. There is a paucity of good quality information regarding the effectiveness of most noncorticosteroid immunosuppressive agents. Older studies of lesser methodological quality have shown benefits from these drugs, generally when added to corticosteroids. Many were retrospective reviews or uncontrolled, nonrandomized, open-label, prospective studies and often included other histological patterns of disease which are now thought to respond better to immunosuppressive agents. The results of intervention with colchicine and azathioprine have been disappointing when assessed by good quality trials using modern diagnostic criteria. Modern high quality studies are lacking for several agents, notably cyclophosphamide and penicillamine. The older agents may yet prove to be effective but further good quality trials will be necessary to assess these agents adequately. Other new anti-inflammatory, antioxidant, antifibrotic or anticytokine compounds are largely untried or unreported. One trial using interferon-gamma-1b showed a significant improvement in pulmonary function but there are concerns regarding the generalizability of this study. Pirfenidone, cyclosporine and acetylcysteine may also prove to be of benefit but current studies are of insufficient quality to allow for any conclusions to be drawn. Currently there is no good evidence to support the routine use of oral corticosteroids, azathioprine, cyclophosphamide, penicillamine, colchicine, cyclosporine or any other immunosuppressive, antifibrotic or immunomodulatory agent in the management of IPF. Interferon, pirfenidone and other new agents may be of benefit but further studies are required. Any recommendations for treatment must therefore be made on an individual and empiric basis. As some other forms of pulmonary fibrosis may respond better to immunosuppressive agents, it remains important to make an accurate diagnosis, by open lung biopsy if necessary.

Abstract
The lung is frequently involved in connective tissue diseases (CTDs), although the frequency of lung manifestations varies according to the type of CTD. Interstitial lung diseases (ILD) are frequently seen in CTDs, particularly systemic sclerosis (SSc), polymyositis/dermatomyositis (PM/DM) and rheumatoid arthritis (RA), accounting for a significant proportion of deaths. A large percentage of patients with CTD-associated ILD has limited and stable disease, not requiring treatment. However, a significant minority has severe and/or progressive disease, necessitating prompt initiation of treatment. CTD-ILD histological patterns include non-specific interstitial pneumonia (NSIP), usual interstitial pneumonia (UIP), organizing pneumonia (OP), diffuse alveolar damage (DAD) and lymphocytic interstitial pneumonia (LIP). NSIP is the most common pattern in all CTDs, except for RA, characterized by a higher frequency of UIP. ILD can present acutely or chronically, with acute presentations being more common in systemic lupus erythematosus and PM/DM. Idiopathic pulmonary fibrosis (IPF) is a progressively worsening ILD characterized by inflammation and fibrosis. The characteristic histological pattern of IPF is UIP. Interestingly, a UIP pattern is associated with a significantly better survival in CTD-related disease compared to the idiopathic variety. Prognosis in IPF is dismal, with a median survival since diagnosis of 2-3 years. No treatment regimen has been shown to improve survival in IPF. By contrast, although there have been only two randomized placebo-controlled trials investigating the effect of immunosuppressive treatment in SSc-associated ILD, clinical experience suggests that immunosuppressive drugs in CTD-related ILDs are capable of benefiting a significant proportion of patients, particularly those with certain histological patterns of disease. This review will essentially focus on CTD-associated ILD and will compare aspects of clinical presentation and management to those of IPF.

Abstract
Systemic autoimmune diseases may be progressive and lead to organ system dysfunction and premature death. Current treatment paradigms are usually predominantly based on the administration of immunosuppressive and/or immunomodulatory drug therapy. Such therapy can stabilize systemic manifestations of connective tissue disease (CTD) and may put the disease into remission, and many of these agents are commonly used to treat CTD-associated interstitial lung disease (ILD). Although these agents have largely revolutionized the treatment of the systemic autoimmune diseases, adverse reactions, which can be serious and life threatening, to the various immunosuppressive agents used in the treatment of CTD can occur. Treating physicians must be aware of mechanisms of action of various immunosuppressive agents and be able to recognize the potential adverse reactions that may occur with therapy as well as potentially harmful effects on fetal development. Appropriate monitoring may prevent or limit toxicity from these agents, and knowledge of drug-drug interactions is essential when these agents are prescribed.

Abstract
Interstitial lung diseases (ILDs) are inflammatory diseases characterized by slow and progressive destruction of alveolar-capillary functional units, often leading to respiratory failure and death. A first stage of alveolitis and a following stage of fibrosis provoke an anatomical distortion of the peripheral airways and the interstitium, and for their smoldering evolution and non-specificity of symptoms ILDs may remain undiagnosed and untreated for a long time. In this review we exploited the immunopathogenetic aspects and the therapeutical approaches to this frequently unrecognized and severe disease.

Abstract
BACKGROUND Idiopathic pulmonary fibrosis is a chronic progressive lung disease with poor outcome and no effective treatment to date. This is an update of a Cochrane Review first published in 2003. OBJECTIVES To assess the efficacy of non-steroid agents in adults with idiopathic pulmonary fibrosis. SEARCH STRATEGY We searched the Cochrane Airways Group Register (30 March 2010), the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library, Issue 1, 2010), Ovid MEDLINE to March week 5, 2010, EMBASE to week 13, 2010 and PubMed to April 2010, with additional handsearching, including abstracts of international conferences. We also contacted pharmaceutical companies and researchers in the field. SELECTION CRITERIA Randomised studies comparing non-steroid drugs with placebo or steroids in adults with idiopathic pulmonary fibrosis. DATA COLLECTION AND ANALYSIS Two authors independently assessed trial quality, extracted data and assessed risk of bias. We contacted pharmaceutical companies to obtain missing information, if any. We combined survival outcomes using Peto odds ratios or hazard ratios (HR). MAIN RESULTS Fifteen trials involving 10 different drugs were included. Two trials enrolling 1156 patients compared interferon gamma-1beta with placebo: interferon gamma-1beta did not significantly improve survival (HR 0.88, 95% CI 0.47 to 1.64; P = 0.68). Four trials involving 1155 patients compared pirfenidone with placebo. Three trials, conducted in 1046 patients, provided data on progression-free survival: pirfenidone significantly reduced the risk of disease progression by 30% (HR 0.70, 95% CI 0.56 to 0.88, P = 0.002). Data on the effect of pirfenidone on pulmonary function could only be assessed for two studies analysing 314 patients. Forced vital capacity or vital capacity was significantly improved by pirfenidone (mean difference 0.08 L, 95% CI 0.03 to 0.13, P = 0.0006). AUTHORS' CONCLUSIONS Based on available data, partly still unpublished, pirfenidone appears to improve progression-free survival and, to a lesser extent, pulmonary function in patients with idiopathic pulmonary fibrosis. More data are needed on overall survival and quality of life on treatment. From the studies in this review, interferon gamma-1beta has not been shown to affect survival. Other agents evaluated in single studies either failed to provide evidence for a benefit or need to be assessed in larger randomised controlled trials.

Abstract
Fibrosis is a pathological process that includes scar formation and overproduction of extracellular matrix by the connective tissue as a response to tissue damage. The fibrotic process involves multiple organs and results in progressive life-threatening diseases. Today, we know more about the molecular mechanism that leads to fibrosis involving different type of cells, cytokines, chemokines, and tissue enzymes. Fibrosis was considered an irreversible process, at least clinically, and is still usually treated by anti-inflammatory and immunosuppressive agents. No proven antifibrotic therapy has shown efficacy in ameliorating the clinical course of fibrotic diseases, but our current understanding led to the development of different drugs with promising results, like: mycophenolate mofetil, interferon, relaxin, and intravenous immunoglobulin. This review will provide a glance to this heavily investigated subject.

Abstract
The Idiopathic Pulmonary Fibrosis (IPF) is a progressive fibrotic lung disease with poor prognosis. It is distinct from other idiopathic interstitial pneumonias by its histopathological pattern of usual interstitial pneumonia which is characterized by accumulation of fibroblasts, extracellular matrix and honeycombing. Inflammation is only scarce in true IPF. The use of anti-inflammatory therapy is still part of guidelines for IPF management, although not specifically recommended, because convincing evidence showing beneficial effects of this approach is lacking. This review provides a summary of important arguments PRO and CON using anti-inflammatory and anti-oxidant therapy for patients with IPF in form of a debate with a concluding statement of both positions at the end.

Abstract
The idiopathic interstitial pneumonias can be grouped, for treatment purposes, into primary inflammatory disorders, fibrotic nonspecific interstitial pneumonia (in which inflammation is thought to precede and progress to fibrosis) as well as the most common of the idiopathic interstitial pneumonia subgroups, idiopathic pulmonary fibrosis. Over the past decade, there have been several paradigm shifts in the understanding of idiopathic interstitial pneumonias and their treatment. In particular, we highlight changes in the use of prognostic markers, clinical trial end points and the understanding of pathogenesis of idiopathic pulmonary fibrosis. We outline a practical approach to the treatment of these three patient groups.

Abstract
As our understanding of the pathobiology and natural history of the various forms of interstitial lung disease (ILD) has evolved, so have our approaches to treating this heterogeneous group of lung disorders. The earliest pharmacologic agents used to treat various forms of ILD were corticosteroids, and corticosteroids are currently the mainstay of therapy for many forms of ILD. However, it has become clear that corticosteroids and other anti-inflammatory agents lack efficacy for many forms of ILD, such as idiopathic pulmonary fibrosis (IPF), and newer therapies that are in clinical trials target the fibrogenic process and/or secondary pulmonary hypertension (PH) that is present in various forms of fibrotic lung disease. Novel therapies, such as the use of biologic agents (antibodies and cell cycle inhibitors) or stem cell therapies will undoubtedly evolve as new research is performed and clinical trials are undertaken. Lung transplantation remains an option for advanced lung disease that is progressive and unresponsive to non-surgical therapies.

Abstract
This study aims to analyze the effects of cyclophosphamide pulse therapy on parameters of lung function in patients with systemic sclerosis. Nineteen patients with systemic sclerosis (15 women and four men, aged 25-67 years, mean disease duration 5 years and 9 months) were included in this study. The main reason for the beginning of cyclophosphamide therapy was the decrease of transfer-factor (DLCO) or diffusing coefficient for carbon monoxide (DLCO/VA) under 70% of predictive value. Intravenous cyclophosphamide was administered monthly in a dose of 500 mg/m(2 )body surface. The efficacy was evaluated by comparison of forced vital capacity (FVC), DLCO, and DLCO/VA at the baseline and 1 month after the sixth pulse. Statistical analyses were performed using Student's T test and Wilcoxon's test. The difference between FVC at the baseline (86.6%) and at the end of the follow-up period (89.2%) was not statistically significant (t=-1.25, p>0.05). However, a significant increase of DLCO (from 61.2% to 70.5%, z=-2.04, p=0.04) and DLCO/VA (from 57.8% to 72.5%, z=-2.67, p=0.008) was observed. Minor side effects were noticed in some patients. Two patients had nausea after cyclophosphamide infusion, two patients had insignificant decrease of creatinine clearance, and two patients had temporary and mild leukopenia. In patients with systemic sclerosis and lung involvement, an improvement of lung-diffusing capacity was noticed 6 months after the beginning of cyclophosphamide pulse therapy, with only minor side effects.

Abstract
STUDY OBJECTIVE To compare the survival of patients with IPF treated retrospectively with corticosteroids alone, to survival of patients treated with immunosuppressive and corticosteroids combined. DESIGN Non-randomized retrospective cohort study. SETTING Three tertiary centers in Brazil. PATIENTS Eighty-two IPF patients were included. The diagnosis was confirmed by open lung biopsy in 48. Patients received either corticosteroids alone (group I) or cytotoxic agents in addition to corticosteroids (group II). MEASUREMENTS AND RESULTS The primary end-point was mortality. Secondary outcome included longitudinal changes in FVC. Mean age was 66+/-8 years. FVC was 71+/-17% of predicted. There were 48 deaths during the study period (59%), 44 secondary to respiratory causes. From preliminary univariate analysis, for the group as a whole, worse survival was found to be associated with FVC% <70% of predicted (P=0.004), evidence of disease progression by follow-up FVC measurements (P=0.01), and pharmacologic treatment (P=0.014). Median survival was 25 months for the group I, and 45 months for the group II (Log-Rank=6.45, P=0.01). After adjusting for FVC > or =70% and<70% of predicted, there was evidence to indicate that survival was associated with recommended pharmacologic treatment only in patients with FVC> or =70% (Log Rank=6.84, P=0.009). CONCLUSIONS The combination of immunosuppressive agents and prednisone results in better survival when compared to prednisone alone in patients with IPF. The benefit seems to occur only in patients with less severe disease, as reflected by FVC> or =70%.

Abstract
Idiopathic pulmonary fibrosis is a disease of unknown cause characterized by cough, progressive dyspnea, restrictive respiratory disorder, a typical honeycomb aspect on the high-resolution CT-scan, and usual interstitial pneumonia at histological examination of the lung biopsy. Most patients die 3 to 8 years after diagnosis. Current treatment is based on a combination of corticosteroids and immunosuppressants, but the efficacy of treatment remains a matter of debate. New therapeutics currently under evaluation in controlled clinical trials include interferon-gamma, pirfenidone, N-acetylcysteine, etanercept (anti-TNFalpha), bosentan (endothelin receptor antagonist), imatinib (tyrosine-kinases inhibitor of the PDGF receptor), etc. At the same time, new compounds showing efficacy in experimental models of fibrosis and the development of new pathophysiological concepts open new perspectives both in terms of concept and clinical practice.

Abstract
Abnormalities in lung function occur in 70% of patients with systemic sclerosis (SSc). Fibrosing alveolitis in SSc (FASSc) is more commonly seen in the diffuse cutaneous form of SSc, particularly in the presence of antitopoisomerase antibodies (Scl70), and with the decreasing incidence of scleroderma renal crisis it is now the major cause of mortality in this patient population. Screening of patients recently diagnosed with SSc by pulmonary function tests and the performance of high resolution computed tomography when physiological abnormalities are identified has resulted in the identification of significant numbers of patients with early, asymptomatic FASSc. Whether these patients should be further investigated with a surgical lung biopsy or receive immunosuppression is unclear, because it cannot yet be reliably predicted who will develop progressive disease and the evidence to support the efficacy of treatment is not strong. The objective of the present article was to review the evidence to support the use of immunosuppressive therapy in FASSc and, based on these data, to propose an algorithm for the investigation and management of this difficult clinical problem.

Abstract
A 48-year-old woman with a follicular, grade III, B-cell non-Hodgkin lymphoma developed clinical, immunopathological and histological features of paraneoplastic pemphigus. The skin symptoms flared after repeated cyclophosphamide infusions, and were preceded and accompanied by a progressive dyspnoea. Although the skin and oral mucosal disease went into remission with high-dose steroid and intravenous immunoglobulin therapy, the severe alveolitis led to death. Immunoblotting of human epidermal extracts showed that the patient's serum IgG reacted with the 210-kDa envoplakin, 190-kDa periplakin, as well as the recombinant protein of BP180 NC16a domain. IgG and IgA enzyme-linked immunosorbent assays for desmoglein 3 were positive, too. Indirect immunofluorescence studies on COS-7 cells transiently transfected with desmocollin 1-3 cDNAs showed that the patient's serum contained IgG and IgA antibodies to desmocollin 3 as well as IgG antibodies to desmocollin 2. Serum IgG and IgA strongly stained rat bronchial epithelium, corresponding to autoantibodies possibly involved in the pathomechanism of the severe lung disease. In this case, which was characterized by a mixed IgA/IgG antibody panel displaying known and unique antigenicity, the serious episodes of paraneoplastic pemphigus flared after cyclophosphamide treatment.

Abstract
The management of sarcoidosis includes several crucial decisions. Not all patients with sarcoidosis need treatment. At least a third of patients will never be treated. It is unclear whether asymptomatic patients ever need therapy, even if they have extensive lung disease. One reason that clinicians are reluctant to start therapy is that many patients who are started on corticosteroids have a difficult time getting off therapy, even after 2 years. In the chronic patient, alternatives to corticosteroids have been developed. These include drugs such as methotrexate, azathioprine and hydroxychloroquine. These agents have been the standard second line of therapy for patients with chronic disease. However, these drugs do not always work. In addition, they are associated with their own toxicities. Another group of sarcoidosis patients have also emerged. These are the refractory patients, who have progressive disease whilst on therapy. For these patients, new agents such as thalidomide and the monoclonal antibodies to tumour necrosis factor have been occasionally helpful. This paper reviews several important issues in the management of sarcoidosis.

Abstract
BACKGROUND Idiopathic Pulmonary Fibrosis (IPF) or Usual Interstitial Pneumonia (UIP) is a form of chronic fibrosing interstitial pneumonia of unknown aetiology, with progressively deteriorating respiratory function and ultimately death from respiratory failure. Most treatments are intended to suppress inflammation but none has been proven to alter this process. The most widespread approach uses oral corticosteroids; others use immunosuppressive, immunomodulatory or anti-fibrotic agents, alone or with corticosteroids. A Cochrane review of corticosteroids in IPF has found no evidence that they are of benefit. OBJECTIVES To determine the effect of non-corticosteroid immunosuppressive, anti-fibrotic and immunomodulatory agents in the treatment of IPF(UIP). SEARCH STRATEGY We searched the Cochrane Central Register of Controlled Trials (CENTRAL - The Cochrane Library, Issue 2 2003), MEDLINE (January 1966 to April 2003), EMBASE (January 1985 to April 2003) and with additional handsearching. SELECTION CRITERIA RCTs/CCTs utilising non-corticosteroid immunosuppressive, anti-fibrotic or immunomodulatory agents versus either placebo or corticosteroids alone in adult patients with histological evidence of IPF(UIP) or with a diagnosis consistent with published American Thoracic Society guidelines were included. DATA COLLECTION AND ANALYSIS We retrieved abstracts of identified articles and reviewed those possibly fulfilling inclusion criteria and included or excluded. Two reviewers assessed the studies for inclusion in the review. Where doubt existed a third reviewer re-assessed the article and consensus was obtained. Methodological quality was assessed using the Jadad scale and the Cochrane assessment of allocation of concealment. MAIN RESULTS 59 studies were identified. Quality was generally poor. Only three RCT/CCTs were suitable for meta-analysis, two lesser quality RCTs were included in discussion only, 52 studies were excluded and two ongoing trials were identified. Each high quality trial used a different agent (azathioprine, colchicine, interferon-gamma 1b) and meaningful comparisons are not possible. Azathioprine and Interferon were studied as additional therapy, whilst colchicine was compared with oral corticosteroids. Only interferon was shown to produce any significant improvement in pulmonary function and arterial oxygenation. There may be a small (but undefined) long term survival advantage for azathioprine. One of the lower quality studies showed a marginal benefit for cyclophosphamide and prednisone over prednisone alone; the other showed no benefit for azathioprine and prednisone over prednisone alone. There are no high quality studies utilising cyclophosphamide. REVIEWER'S CONCLUSIONS There is little good quality information regarding the efficacy of non-corticosteroid agents in IPF(UIP). The older agents have generally not been well evaluated. A number of new agents require further evaluation. Currently there is little to justify the routine use of any non-corticosteroid agent in the management of IPF(UIP).

Abstract
The treatment of interstitial lung disease usually has consisted of corticosteroids with or without either azathioprine or cyclophosphamide. These drugs mainly target the neutrophil. Recently, the role of the Th2 lymphocyte leading to fibrosis has been demonstrated in animal models and preliminary human studies. This finding has led to interest in cytokine therapy with the interferon treatments, which reduce the Th2 response. Other new treatments have focused specifically on the fibroblast or oxygen free radicals. The range of treatment for interstitial lung diseases is increasing. Current clinical trials are in progress to confirm the pilot studies recently reported. The future therapy of interstitial lung disease probably will consist of multiple agents aimed at several aspects of the inflammatory reaction of interstitial lung disease.

Abstract
Idiopathic pulmonary fibrosis is a rapidly progressive illness of unknown cause characterized by sequential acute lung injury with subsequent scarring and end-stage lung disease. Treatment at present remains largely supportive, with evidence that patients' satisfaction and survival may be improved by referral to centers specializing in the evaluation of interstitial lung diseases. Although no drug therapy has clearly been demonstrated to benefit patients with idiopathic pulmonary fibrosis, a number of novel investigational agents hold promise for future study. Given the poor prognosis associated with idiopathic pulmonary fibrosis, patients should be referred to regional centers of expertise for enrollment in therapeutic clinical trials or for lung transplantation.

Abstract
Bronchoalveolar lavage remains an important research tool in understanding ILD. It is still an important part of the clinical management of patients with ILD. It is most useful in detecting unusual forms of ILD. It helps the clinician narrow down the possible causes of the interstitial pattern. It also can confirm a clinical impression of certain conditions. Although rarely diagnostic, it is often supportive. In conjunction with high-resolution CT scan, most patients with ILD can be diagnosed using relatively noninvasive methods.

Abstract
Little attention has been paid to quality of life (QOL) in idiopathic pulmonary fibrosis (IPF). Therefore, the aim of this study was to address this issue and study the relationship between QOL, depressive symptoms, and breathlessness in these patients. Forty-one IPF patients and 41 healthy persons matched for age and sex completed the World Health Organization Quality of Life assessment instrument-100. The IPF patients also completed the Beck Depression Inventory, the Bath Breathlessness Scale, a social support questionnaire and a question concerning perceived seriousness of illness. Compared to the control group, QOL in IPF patients was mainly impaired in the domains "physical health" and "level of independence". A number of relationships were found between pulmonary function tests and QOL. The QOL facet "negative feelings" was highly associated with scores on depression. Subjective breathlessness was related to depressive symptoms and QOL. Moreover, sex and effective/emotional breathlessness predicted overall QOL. In conclusion, the impairment of the quality of life areas "physical health" and "level of independence" are important issues in idiopathic pulmonary fibrosis. Subjective breathlessness, especially the effective/emotional scale, seems related to quality of life and depressive symptoms. Rehabilitation programmes are needed that are aimed at physiological aspects and psychosocial aspects of idiopathic pulmonary fibrosis in order to enhance the quality of life of these patients.

Abstract
STUDY OBJECTIVES To prospectively examine the role of cyclophosphamide in patients with idiopathic pulmonary fibrosis that is unresponsive to or intolerant of high-dose steroid treatment. DESIGN Prospective study. SETTING Tertiary referral center. PATIENTS Nineteen patients with biopsy specimen-proven usual interstitial pneumonia who failed to respond (n = 16) or experienced adverse effects (n = 3) from corticosteroid treatment (1 mg/kg/d for 3 months). INTERVENTION Steroid therapy was tapered quickly, and oral cyclophosphamide, 2 mg/kg/d, was prescribed (mean duration of treatment, 6.0 +/- 0.9 months). MEASUREMENTS AND RESULTS In 10 patients, response to therapy was determined by pretreatment and posttreatment clinical (dyspnea), radiographic (chest radiograph), and physiologic (pulmonary function, including exercise saturation) scores (CRP). Response was defined as a > 10-point drop in CRP; stable as +/- 10-point change in CRP; and nonresponders as > 10-point rise in CRP. In nine patients, physiologic criteria were used to assess response; significant changes in pulmonary function were defined as follows: total lung capacity, +/- 10% of baseline value; FVC, +/- 10% of baseline value, diffusion capacity of the lung for carbon monoxide, +/- 20% of baseline value; and resting pulse oximetry, +/- 4% of baseline value. Patients who died while receiving or shortly after discontinuing cyclophosphamide were classified as nonresponders (n = 2). Among 19 patients treated with cyclophosphamide, only 1 patient demonstrated sustained response; 7 patients remained stable and 11 deteriorated while receiving the drug. Toxicity associated with cyclophosphamide was substantial; more than two thirds of the patients developed drug-related adverse effects, and almost half discontinued the drug prematurely due to side effects. In the remaining patients, cyclophosphamide therapy was discontinued due to lack of improvement or progressive deterioration. CONCLUSIONS Cyclophosphamide therapy is of limited efficacy in patients with idiopathic pulmonary fibrosis who fail to respond or who experience adverse effects from corticosteroid treatment, and adverse effects often complicate its use.

Abstract
Idiopathic pulmonary fibrosis (IPF) is a condition that has a poor prognosis, with a median survival of 4-5 years irrespective of treatment. Ziesche et al (N Engl J Med 1999, 341: 1264-1269) describe an open randomised trial of 18 patients with IPF, unresponsive to corticosteroid treatment at high dose. Nine patients were treated with continued corticosteroid and nine with prednisolone plus interferon-gamma 1b (IFN-gamma). Significant benefits in physiological parameters are reported in the IFN-gamma-treated group. An analysis of lung tissue by reverse-transcriptase-mediated polymerase chain reaction showed corresponding decreases in the transcription of transforming growth factor-beta1 and connective tissue growth factor. This is the first report of treatment showing efficacy in this disease, albeit in a very preliminary study, but the data should be viewed with caution. This study is discussed in the context of other published studies of treatment for IPF and the scientific rationale on which it was based.

Abstract
Idiopathic pulmonary fibrosis (IPF) is generally defined as a progressive, fibrosing inflammatory disease of the lung parenchyma of unknown cause. It is characterized by slowly increasing dyspnea, diffuse interstitial lung infiltrates, restrictive lung dysfunction, and impaired gas exchange. Ultimately, it is fatal in most patients, and treatment options remain unsatisfactory. The advent of high-resolution computed tomography of the chest and modifications in the histopathologic classification of interstitial pneumonias have reshaped the concept of IPF. Although initially thought to be a relatively specific clinicopathologic entity, it seems likely that IPF as previously defined is a heterogeneous disorder consisting of several clinicopathologic entities with differing histopathologic patterns, clinical course, response to therapy, and prognosis. The most common histologic pattern in cases previously defined as IPF is usual interstitial pneumonia, which is associated with a median survival of less than 3 years. For accurate prognosis and optimal management of patients, the clinician should attempt to be as precise as possible in distinguishing various clinicopathologic entities that have been included under the clinical heading of IPF. In the future, we recommend that the use of the term "idiopathic pulmonary fibrosis" be restricted to patients with usual interstitial pneumonia and that clinicians recognize the fact that other idiopathic interstitial pneumonias do not have the same prognostic effect traditionally ascribed to IPF.

Abstract
Patients with diffuse interstitial lung diseases (DILD) are challenging to treat. Many patients with DILD have inadequate information about the disease process, an imprecise diagnosis, unsatisfactory treatment or unacceptable side effects associated with therapy, and poorly controlled symptoms of progressive illness. Establishing an accurate diagnosis is necessary so that the patient and his/her family can be provided with reasonable expectations about prognosis and outcome from therapy. A pragmatic approach is presented that emphasizes diagnostic strategies and plans for therapy that are effective and resource efficient and that will help maintain patient satisfaction.

Abstract
OBJECTIVE To assess the results with colchicine and prednisone as initial single-drug therapy in patients with usual interstitial pneumonia (UIP). MATERIAL AND METHODS We reviewed the serial pulmonary function test results in 22 patients with typical clinical and high-resolution computed tomographic features of UIP who were treated with colchicine as initial single-agent therapy and compared them with a group of 22 historical patients with UIP of similar severity diagnosed by open-lung biopsy who were given prednisone as initial single-drug therapy. RESULTS No significant difference was detected in the rate of decline of pulmonary function or in the time to "failure" between the two study groups. A trend was suggested for more rapid decline of pulmonary function in the prednisone-treated than in the colchicine-treated group. The design of this study does not allow distinction between a possible beneficial effect of colchicine and a possible adverse effect related to weaning from high-dose prednisone. Colchicine was well tolerated; few side effects other than mild diarrhea were noted in those patients able to take the drug long enough to return for pulmonary function testing at 3 months. In comparison, the side effects of prednisone were more serious and were not always reversible with cessation of therapy. CONCLUSION This study lends further support to the assumption that colchicine may be a satisfactory and less hazardous substitute for prednisone in the treatment of patients with UIP.

Abstract
The interstitial lung diseases (ILD) are a heterogeneous group of disorders the most common of which is cryptogenic fibrosing alveolitis (CFA). This article has summarized recent work in particular on the diagnosis, pathogenesis and treatment of CFA, by reviewing published data accessed through Medline searching. Recent reports suggest a higher prevalence of CFA than previously documented (13.2-20.2/100,000 population) and a rising mortality rate. The prognosis is universally poor with 50% of patients dying within 5 years. Although approximately 30% of patients may live for long periods (> 10 years), morbidity is significant and quality of life in the long-term survivors is poor. Diagnosis is traditionally based on an open lung biopsy, however, more recently the high resolution computer tomography (HRCT) is often used; however, its use without a tissue diagnosis remains controversial. In conclusion, we know substantially more about the pathogenesis of the disease and from this work have a number of possibilities for new therapeutic strategies that will hopefully reach the bedside in the near future. Additionally we have some new non-invasive tests that offer hope for stratifying patients but require further evaluation. For assessing both therapy and investigations we will need substantial groups of patients in multicentre studies to provide sufficient power to allow a conclusion to be reached. To ensure any further progress we must collaborate and enter our patients into such trials.

Abstract
Fibrotic process affecting the lung and other tissues is characterized by stimulation of fibroblast proliferation and connective tissue deposition. Conventional therapy consisting of glucocorticoids or cytotoxic agents is usually ineffective in blocking progression of disease. Potential new therapies have emerged from the use of animal models of pulmonary fibrosis and recent advances in the cellular and molecular biology of inflammatory reactions. Such therapies involve the use of substances directed against the action of certain growth factors, cytokines, or oxidants that are elaborated during the fibrotic reaction. In this article, we review possible therapeutic applications of these advances.
