Hrct Patterns

Background:Interstitial lung disease (ILD) is a common manifestation of connective tissue diseases (CTDs), and is associated with significant morbidity and mortality. Chest high-resolution computed tomography (HRCT) play an important role in the diagnosis of ILD and may provide prognostic information.Objectives:We aimed to characterize the clinical profile and chest HRCT abnormalities and patterns of patients diagnosed with CTDs and ILD.Methods:In this retrospective, observational study we included 80 consecutive patients with CTDs and ILD referred to a tertiary rheumatology center between 2015 and 2019. From hospital charts we collected clinical data, immunologic profile, chest HRCT findings. HRCT patterns were defined according to new international recommendations.Results:Out of 80 patients, 64 (80%) were women, with a mean age of 55 years old. The most common CTD associated with ILD was systemic sclerosis (38.8%), followed by polymyositis (22.5%) and rheumatoid arthritis (18.8%). The majority of patients had dyspnea on exertion (71.3%), bibasilar inspiratory crackles were present in 56.3% patients and 10% had clubbing fingers. Antinuclear antibodies (ANA) were present in 78.8% patients, and the most frequently detected autoantibodies against extractable nuclear antigen were anti-Scl 70 (28.8%), followed by anti-SSA (anti-Ro, 17.5%), anti-Ro52 (11.3%) and anti-Jo (7.5%). Intravenous cyclophosphamide therapy for 6-12 months was used in 35% of patients, while 5% of patients were treated with mycophenolate mofetil.The most frequent HRCT abnormalities were reticular abnormalities and ground glass opacity. Non-specific interstitial pneumonia (NSIP) was identified in 46.3% CTDs patients. A pattern suggestive of usual interstitial pneumonia (UIP) was present in 32.5% patients, mainly in patients with systemic sclerosis. In 21.3% patients the HRCT showed reticulo-nodular pattern, micronodules and other abnormalities, not diagnostic for UIP or NSIP pattern.Conclusion:Nonspecific interstitial pneumonia (NSIP) is the most common HRCT pattern associated with CTDs. Further prospective longitudinal studies are needed in order to determine the clinical and prognostic significance of various HRCT patterns encountered in CTD-associated ILD and for better patient management.References:[1]Ohno Y, Koyama H, Yoshikaua T, Seki S.

Acute Interstitial Pneumonia

BACKGROUND Interstitial lung disease (ILD) is an unpredictable diffuse parenchymal lung disease, which involves interstitium of lung (tissue around the alveoli of the lungs). High resolution computed tomography (HRCT) is one of the confirmatory, easily accessible methodology for the conclusion and follow up assessment of interstitial lung disease. We wanted to study the normal HRCT patterns found with interstitial lung disease and contrastingly different HRCT designs and clinical information in differential determination of pulmonary fibrosis. We also wanted to study the different patterns of interstitial lung disease on high resolution computed tomography and thereby provide accurate diagnosis and management to the patients. METHODS The study was a hospital based prospective, cross sectional study. In the present study, total fifty patients referred from Department of Medicine and Department of Pulmonary Medicine of GCS Medical College having suspicion of interstitial lung disease were studied from April 2019 to September 2019. All patients underwent HRCT thorax on 16 slice Siemens computerised tomography (CT) scan machine in recumbent position utilising usual HRCT protocol. Lung abnormalities were noticed and classified for explicit diagnosis of interstitial lung pathologies. RESULTS Most of the patients (N = 25) were found to be in the age group of 50 - 80 years (17 female & 8 male). Progressive dyspnoea (N = 47; 94 %) was the most common chief complaint. The most common form of interstitial lung disease was usual interstitial pneumonia (UIN) (N = 18; 36 %) in our study. Acute interstitial pneumonia (AIP) (N = 7; 14 %) and non-specific interstitial pneumonia, NSIP (N = 7; 14 %) were the next common interstitial lung diseases. CONCLUSIONS The most well-known interstitial lung disease seen in our examination was usual interstitial pneumonia. Cases of interstitial lung disease are on the rise. Interstitial lung disease should be ruled out in all patients with progressive dyspnoea, particularly when there are no obvious or known causes of dyspnoea. Clinical and laboratory findings, pulmonary function tests, history of exposure along with HRCT workup is indispensable for the identification or exclusion of interstitial lung disease. HRCT is also useful for the follow-up study.

Evaluation And Monitoring

Patients with systemic sclerosis are at high risk of developing systemic sclerosis–associated interstitial lung disease. Symptoms and outcomes of systemic sclerosis–associated interstitial lung disease range from subclinical lung involvement to respiratory failure and death. Early and accurate diagnosis of systemic sclerosis–associated interstitial lung disease is therefore important to enable appropriate intervention. The most sensitive and specific way to diagnose systemic sclerosis–associated interstitial lung disease is by high-resolution computed tomography, and experts recommend that high-resolution computed tomography should be performed in all patients with systemic sclerosis at the time of initial diagnosis. In addition to being an important screening and diagnostic tool, high-resolution computed tomography can be used to evaluate disease extent in systemic sclerosis–associated interstitial lung disease and may be helpful in assessing prognosis in some patients. Currently, there is no consensus with regards to frequency and scanning intervals in patients at risk of interstitial lung disease development and/or progression. However, expert guidance does suggest that frequency of screening using high-resolution computed tomography should be guided by risk of developing interstitial lung disease. Most experienced clinicians would not repeat high-resolution computed tomography more than once a year or every other year for the first few years unless symptoms arose. Several computed tomography techniques have been developed in recent years that are suitable for regular monitoring, including low-radiation protocols, which, together with other technologies, such as lung ultrasound and magnetic resonance imaging, may further assist in the evaluation and monitoring of patients with systemic sclerosis–associated interstitial lung disease.

Introduction: There is a paucity of real-world data on mycophenolate mofetil/mycophenolate sodium in systemic sclerosis-related interstitial lung disease. Aim: To study the efficacy of mycophenolate mofetil/ mycophenolate sodium in systemic sclerosis-related interstitial lung disease. Methods: In this single-centre study, clinical, laboratory and imaging details of consecutive patients with systemic sclerosis-related interstitial lung disease receiving mycophenolate mofetil/mycophenolate sodium from rheumatology and pulmonology clinics between January 2008 and March 2017 were retrospectively retrieved. The change in percentage of predicted normal forced vital capacity at last follow-up visit as compared with baseline was studied. In addition, high-resolution computed tomography scans at baseline and 2-year follow-up visit were scored as either stable/improved or worsened by experienced thoracic radiologists blinded to the clinical details of patients. Results: Altogether, 88 patients (85.2% females) with mean age (SD) of 33.8 years (± 11.3) and median (interquartile range) duration of disease since non-Raynaud’s symptoms of 36 months (13.5–60) were studied. Diffuse systemic sclerosis comprised 85.2% of them. The mean baseline forced vital capacity was 61.2 ± 17.9% and median scores for ground glass opacities and fibrosis in high-resolution computed tomography were 0.5 (0–1.3) and 1 (0–1.3), respectively. At a median follow-up duration of 30 months (interquartile range = 16.5–49), the percentage of forced vital capacity improved by 1.8% (–3.82 to 9.07) as compared with baseline visit ( p = 0.02). In the 2-year follow-up, the ground glass opacity and fibrosis scores in high-resolution computed tomography improved in 17.3% and 7.7% of patients and stabilized in 63.5% and 78.8% patients, respectively. Conclusion: Mycophenolate mofetil/mycophenolate sodium was efficacious in improving /stabilizing forced vital capacity irrespective of the baseline high-resolution computed tomography lung scores in our patients with systemic sclerosis-related interstitial lung disease during the ⩾ 2-year follow-up period.
