CLINICAL CHARACTERISTICS AND OUTCOME OF PATIENTS WITH INTERSTITIAL PNEUMONIA WITH AUTOIMMUNE FEATURES COMPARED TO CONNECTIVE TISSUE DISEASE RELATED-INTERSTITIAL LUNG DISEASE AND IDIOPATHIC PULMONARY FIBROSIS

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.

Data Registry

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.
