 Good morning. Myself, Dr. Shabnam Parvi, post-casual trainee in the Department of Radio Diagnosis, IPG MIR, and IPG MIR Polkata. Title of my presentation is HRCT thorax findings in nematode arthritis and its correlation with spirometric indices. The nematode arthritis is a systemic inflammatory disease most commonly affect the joint and usually associated with auto antibody production. Plural pulmonary complications are responsible for significantly increased morbidity and mortality. Lung involvement ranges between 67 to 10 percent in defense studies. Pulmonary involvement accounts for 10 to 20 percent mortality. Common nematode arthritis associated IELDSAR, non-specific interstitial pneumonia, usual interstitial pneumonia, organizing pneumonia, DIP, LIP, diffuse alveolar damage and acute interstitial pneumonia. High tidal of nematode factor, anti-CCP, IR age, male gender, family history of nematode arthritis, smoking, et cetera, increases the likelihood for developing nematode arthritis associated IELD. In the aims and objective of the studies, where assessment of pulmonary affection according to duration of the disease process, pattern and frequency of findings on HRCT thorax, correlation of spirometric indices with HRCT findings. We use the studies for review of literature. This was a cross-sectional observation on the study. Sample size was 50. It had been conducted in the Department of Radiogenesis and Metrology, Pulmonary Medicine in IPG email. Inclusion criteria as a patient within 55 years of age after satisfying clinical examination, we see a similar criteria of hematode arthritis with pulmonary symptoms. Exclusion criteria as a patient with history of pulmonary TB, chest radiation, injury, lung transplantation, occupational lung disease, connective tissue disorder, and pregnant patient. Now coming into result and analysis. There is female preponderance, male is to female ratio, was two is two, two is two one, and we divided the patients according to duration of the disease early up to five years and late more than five years. In HRCT findings, the most common findings was down glass opacity followed by bronchiopterosis, interstitial thickening, rural thickening. Lung involvement in HRCT thorax was 45% in early disease group and 84% in late disease group. Correlation between disease duration and lung involvement in HRCT is statistically significant. We also found that 99.6% patients had rheumatoid arthritis associated ILD in early disease group and 52.6% patient had rheumatoid arthritis associated ILD in late disease group. Rheumatoid arthritis associated ILD and correlation between disease duration and ILD pattern in HRCT is statistically significant. 43% patients were having ILD among the patient with lung involvement and USIP pattern was maximum. This is the cross table between spirometry and lung involvement in HRCT thorax in early and late disease group. And correlation between HRCT thorax and pattern of spirometry is more significant in late disease group. 43 years old female patient with 2 years of disease duration shows air trapping in basal segment of bilateral lower lobes. 43 years old female patient with 9 years of disease duration shows small sub plural ground glass nodules in apicoposterior segment of left upper lobe and postrovisal segment in right lower lobe. HRCT thorax in 50 years old female with 1 year disease duration shows GGO and fibrosis with fractional bone care passes in both lower lobes and medial senile window shows multiple different sizes medial senile lymph nodes in pariotic and left paratracheal region. It was an NSIP with medial senile lymph adenopathy. HRCT thorax of 42 year male patient with 8 years history of rheumatoid arthritis shows honey combi throughout the lung field predominantly in the lower lobe with few patchy areas of ground glass opacity. And there is evidence of peri bronchial vascular interstitial thickening with fractional bronchial passes in both lungs. The axial medial senile window shows ratio between pulmonary artery and ascending outer is more than one. This is a case of usual interstitial pneumonia with pulmonary artery hypertension. Discussion female and male ratio is 2 to 1 in our study 62% patients were disease duration of less than 5 years and 38% patients were disease duration of more than 5 years. Most common findings in HRCT thorax is GGO followed by interstitial thickening, pleural thickening and air trapping. Correlation between disease duration and lung involvement and eyelid pattern in HRCT is statistically significant. Most common type of rheumatoid arthritis associated ILD is USIP pattern and correlation between spirometry and lung involvement in early and late disease group of rheumatoid arthritis is highly significant. So we conclude that type and manifestation of lung disease in rheumatoid arthritis varies and can easily affect any lung compartment, including lung panenchyma, pleura, airways and vasculature. In this study, UIP is most common ILD and GGO is most common findings. As the duration of illness increases, need for spinning of pulmonary involvement with PFDs and HRCT is to be emphasized along with periodic chest examination. Thank you.
