Our study compared the prevalence and characteristics of patients with connective tissue disease-associated interstitial lung disease (CTD-ILD), undifferentiated connective tissue disease-associated interstitial lung disease (UCTD-ILD), or idiopathic pulmonary fibrosis (IPF) between January 2009 and December 2012 in West China Hospital, western China. Patients who met the criteria for ILD were included and were assigned to CTD-ILD, UCTD-ILD, or IPF group when they met the criteria for CTD, UCTD, or IPF, respectively. Clinical characteristics, laboratory tests, and high-resolution CT images were analyzed and compared among three groups. 203 patients were included, and all were Han nationality. CTD-ILD was identified in 31%, UCTD-ILD in 32%, and IPF in 37%. Gender and age differed among groups. Pulmonary symptoms were more common in IPF, while extrapulmonary symptoms were more common in CTD-ILD and UCTD-ILD group. Patients with CTD-ILD had more abnormal antibody tests than those of UCTD-ILD and IPF. Little significance was seen in HRCT images among three groups. A systematic evaluation of symptoms and serologic tests in patients with ILD can identify CTD-ILD, UCTD-ILD, and IPF.

Heterogeneous Group

Interstitial lung diseases are a complex heterogeneous group which are challenging to diagnose and treat. The diagnosis of idiopathic pulmonary fibrosis, as opposed to connective tissue interstitial lung disease, is important, as treatments and prognoses are very different. This chapter focusses on a case where this diagnosis is challenging. The evidence for the treatment of idiopathic pulmonary fibrosis is reviewed, in light of recent trials and new recommendations.

Fibrotic Lung Diseases

Progressive fibrosing interstitial lung disease (PF-ILD) describes a phenotypic subset of interstitial lung diseases characterized by progressive, intractable lung fibrosis. PF-ILD is separate from, but has radiographic, histopathologic, and clinical similarities to idiopathic pulmonary fibrosis. Two antifibrotic medications, nintedanib and pirfenidone, have been approved for use in patients with idiopathic pulmonary fibrosis. Recently completed randomized controlled trials have demonstrated the clinical efficacy of antifibrotic therapy in patients with PF-ILD. The validation of efficacy of antifibrotic therapy in PF-ILD has changed the treatment landscape for all of the fibrotic lung diseases, providing a new treatment pathway and opening the door for combined antifibrotic and immunosuppressant drug therapy to address both the fibrotic and inflammatory components of ILD characterized by mixed pathophysiologic pathways.

Antifibrotic Therapy

Introduction. The natural course of some interstitial lung diseases (ILD) is characterized by progressive fibrosing phenotype resembling idiopathic pulmonary fibrosis (IPF). Until recently, the antifibrotic drug nintedanib was approved for treatment of the only fibrosing ILD which was IPF. A new indication for this drug which has been registered in Russian Federation in 2021 includes other fibrosing ILDs with progressive phenotype (PF-ILDs) and ILD associated with systemic scleroderma (SS-ILD).The aim of this publication is to describe general considerations of the decision of Multidisciplinary Expert Board on diagnosis and treatment of PF-ILDs including SS-ILD.Results. According to the extension in nintedanib use mentioned above, the Expert Board created an algorithm for diagnosis and treatment of patients with PF-ILDs and criteria for nuntedanib administration in PF-ILDs.Conclusion. Antifibrotic therapy is needed for patients with PF-ILDs with the failure of the stanrard therapy. In those patients antifibrotic treatment should be initiated as early as possible to better preserve the lung function.

Abstract Disclaimer In an effort to expedite the publication of articles, AJHP is posting manuscripts online as soon as possible after acceptance. Accepted manuscripts have been peer-reviewed and copyedited, but are posted online before technical formatting and author proofing. These manuscripts are not the final version of record and will be replaced with the final article (formatted per AJHP style and proofed by the authors) at a later time. Purpose This article summarizes the appropriate use and pharmacology of treatments for fibrosing interstitial lung diseases, with a specific focus on the antifibrotic agents nintedanib and pirfenidone. Summary The interstitial lung diseases are a heterogenous group of parenchymal lung disorders with a common feature—infiltration of the interstitial space with derangement of the normal capillary-alveolar anatomy. Diseases characterized by fibrosis of the interstitial space are referred to as the fibrosing interstitial lung diseases and often show progression over time: idiopathic pulmonary fibrosis is the most common fibrotic interstitial lung disease. Historically, therapies for fibrosing lung diseases have been limited in number, questionable in efficacy, and associated with potential harms. Food and Drug Administration (FDA) approval of the antifibrotic agents nintedanib and pirfenidone for idiopathic pulmonary fibrosis in 2014 heralded an era of reorganization of therapy for the fibrotic interstitial lung diseases. Subsequent investigations have led to FDA approval of nintedanib for systemic sclerosis–associated interstitial lung disease and interstitial lung diseases with a progressive phenotype. Although supportive care and pulmonary rehabilitation should be provided to all patients, the role(s) of immunomodulators and/or immune suppressing agents vary by the underlying disease state. Several agents previously used to treat fibrotic lung diseases (N-acetylcysteine, anticoagulation, pulmonary vasodilators) lack efficacy or cause harm. Conclusion With the introduction of effective pharmacotherapy for fibrosing interstitial lung disease, pharmacists have an increasingly important role in the interdisciplinary team managing these patients.

Objectives: The burden of interstitial lung disease (ILD) is rising globally. This study aimed to describe and compare characteristics of Connective Tissue Disease-associated ILD with Idiopathic Pulmonary Fibrosis, the two most commonly observed ILDs among outpatients at a tertiary care hospital in Karachi, Pakistan. Methods: A retrospective research study was conducted. Patients with ILD were identified through the outpatient data registry at the Aga Khan University Hospital (AKUH), Karachi from October 2016 to October 2017. We obtained data pertaining to demographics, clinical and radiologic features. A comparative analysis was done to compare the patient characteristics and key features between CTD-ILD and IPF patients. The analysis was done using STATA version 12.0. Results: We identified 184 patients with ILD, which included 52 (29.3%) with CTD-ILD and 62 (35%) with IPF. The most prevalent conditions among CTD-ILD patients included rheumatoid arthritis (42.3%) and scleroderma (25%). Usual interstitial pneumonitis was the common radiologic pattern in RA-ILD (63.6%) and scleroderma (61.5%) while non-specific interstitial pneumonitis was more common in MCTD (85.7%) and SLE (80%). Compared to patients with IPF, those with CTD-ILD were predominantly younger (p<0.001) and female (88.5 % v 45.2%, p<0.001). History of GERD was also significantly lower in CTD-ILD (p=0.05). Conclusion: CTD-ILD patients in our registry were younger and predominantly female compared to IPF. Further studies and ongoing data registry are needed to understand the full spectrum of this disease and long term clinical outcomes.

Introduction: The goal of this study is to determine whether Advanced glycosylated end-products (AGE), Advanced oxidation protein products (AOPP) and Matrix metalloproteinase 7 (MMP7) could be used as differential biomarkers for idiopathic pulmonary fibrosis (IPF) and connective tissue disease-associated interstitial lung disease (CTD-ILD). Method: Seventy-three patients were enrolled: 29 with IPF, 14 with CTD-ILD, and 30 healthy controls. The study included a single visit by participants. A blood sample was drawn and serum was analysed for AGE using spectrofluorimetry, AOPP by spectrophotometry, and MMP7 using sandwich-type enzyme-linked immunosorbent assay. Results: AGE, AOPP and MMP7 serum levels were significantly higher in both IPF and CTD-ILD patients versus healthy controls; and AGE was also significantly elevated in CTD-ILD compared to the IPF group. AGE plasma levels clearly distinguished CTD-ILD patients from healthy participants (AUC = 0.95; 95% IC 0.86–1), whereas in IPF patients, the distinction was moderate (AUC = 0.78; 95% IC 0.60–0.97). Conclusion: In summary, our results provide support for the potential value of serum AGE, AOPP and MMP7 concentrations as diagnostic biomarkers in IPF and CTD-ILD to differentiate between ILD patients and healthy controls. Furthermore, this study provides evidence, for the first time, for the possible use of AGE as a differential diagnostic biomarker to distinguish between IPF and CTD-ILD. The value of these biomarkers as additional tools in a multidisciplinary approach to IPF and CTD-ILD diagnosis needs to be considered and further explored. Multicentre studies are necessary to understand the role of AGE in differential diagnosis.
