Abstract Background The data on medium-term follow-up of coronavirus disease-19 (COVID-19) pneumonia survivors is scarce. Medium-term follow-up will generate knowledge and help in devising a structured follow-up plan and to facilitate enrolment in clinical trials assessing the role of antifibrotic drugs in modifying the course of disease in order to avert long-term pulmonary sequelae of disease. The study was aimed to evaluate the lung findings on a medium-term follow-up (3 months or more) chest computed tomography (CT) in COVID-19 pneumonia survivors, assess the rate of resolution or persistence of lung abnormalities and to identify the initial demographic, clinical, and imaging characteristics that could potentially predict the persistence of lung abnormalities on follow-up. Results Out of the total study cohort of 81 patients, 46 (56.8%) demonstrated complete resolution of lung findings and the remaining 35 (43.2%) had residual lung opacities on follow-up CT. The most common type of residual abnormality was ground glass opacity (GGO) (16/35; 45.7%), followed by parenchymal bands (9/35; 25.7%), mixed pattern of GGO and parenchymal bands (6/35; 17.2%), bronchiectasis (6/35; 17.2%), and interlobular septal thickening (4/35; 11.4%). Patients with residual abnormalities were older, had higher BMI, more comorbidities, lower SpO2, longer hospital stay, higher rate of intensive care unit (ICU) admission, higher WBC count, a higher CT severity score, and lower rate of steroid administration with all p values < 0.05. Conclusion Nearly half of post-COVID-19 survivors had residual lung abnormalities after ≥ 3 months of follow-up. Certain clinico-radiological characteristics have the potential to identify the individuals at risk of having residual lung abnormalities on medium-term follow-up.

ABSTRACT Objectives Microscopic polyangiitis (MPA) affects various organs. However, echocardiographic findings of MPA are unclear. We aimed to evaluate the echocardiographic features of acute-phase MPA in Japanese patients. Methods This single-centre retrospective study included 15 patients with MPA who underwent echocardiography within 2 weeks of commencing steroid therapy for induction or reinduction. The echocardiography parameters of thetients were compared with those of 30 age- and sex-matched controls. Results No significant differences in left ventricular (LV) diameter, LV ejection fraction, or e’ were observed between the two groups. However, the MPA group showed a significantly higher left atrial (LA) diameter and LA volume index, as well as higher early diastolic filling velocity, diastolic pulmonary venous flow velocity, and trans-tricuspid pressure gradient, and a shorter deceleration time (DCT). Serum C-reactive protein levels were positively correlated with E wave, E/A, and DCT. These results may indicate that increased LV stiffness, rather than impairment of LV relaxation, contributed to LV diastolic function, resulting in LA enlargement. Conclusions Patients with acute-phase MPA had LA dilatation associated with LV diastolic dysfunction. This finding indicates the importance of cardiac assessment in patients with MPA, especially in patients with a strong inflammatory reaction.
