Comparison of Two Corticosteroid Regimens for Post COVID-19 Diffuse Lung Disease

Study Purpose

A proportion of patients with COVID-19 pneumonia have a prolonged course of illness. Some of these patients continue to have considerable respiratory symptoms or persistent hypoxemia. The CT abnormalities in these patients are often a combination of ground-glass opacities and patchy multifocal consolidation consistent with a pattern of OP. In several patients, these radiologic abnormalities persist. As with other forms of OP, patients with post-COVID OP or post COVID diffuse lung disease (PC-DLD) may benefit from treatment with oral glucocorticoids. The ideal dose of glucocorticoids for treating PC-DLD is unknown. In this study, the investigatros aim to compare the efficacy and safety of a medium dose and a low dose of prednisolone (as the initial dose) for the treatment of post-COVID. diffuse lung disease.

Recruitment Criteria

Accepts Healthy Volunteers Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms	No
Study Type An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes. An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes. Searching Both is inclusive of interventional and observational studies.	Interventional

Additional Details

A proportion of patients with COVID-19 pneumonia (with or without ARDS) have a prolonged course of illness. Some of these patients continue to have considerable respiratory symptoms or persistent hypoxemia. The CT abnormalities in these patients are often a combination of ground-glass opacities and patchy multifocal consolidation consistent with a pattern of OP. In several patients, these radiologic abnormalities persist even after the symptoms of active COVID-19 have subsided and swabs from the upper respiratory tract for SARS-CoV-2 have turned negative. Such patients may be classified as having a secondary form of OP, namely post-infectious OP. Some of the patients also start developing signs of fibrosis. As with other forms of OP, patients with post-COVID OP or post COVID diffuse lung disease (PC-DLD) may benefit from treatment with oral glucocorticoids. Glucocorticoids may be a double-edged sword in this clinical situation. Steroids reduce inflammation associated with OP with a resultant resolution of symptoms, improvement in gas exchange (resulting in the resolution of hypoxemia), and potentially preventing the progression of early parenchymal abnormalities to irreversible fibrosis. However, they are associated with adverse effects such as hyperglycemia, delayed viral clearance, and increased susceptibility to infections. The ideal dose of glucocorticoids for treating PC-DLD is unknown. As PC-DLD is likely to get recognised early (much earlier than the average duration between onset of symptoms and diagnosis in other forms of OP, i.e., about 3-6 months), there is a possibility a lower intensity of glucocorticoids may be sufficient for treatment than the usual regimens, with the advantage of lesser adverse effects. A previous retrospective study that compared two regimens (higher dose intensity [DI] of glucocorticoids alone vs.#46; glucocorticoids at a lower dose intensity along with clarithromycin), however, found that a complete radiologic response was higher in the prednisone alone (higher DI) group (81% vs.#46; 63%) than in the combination group (with a lower DI of prednisone). Statistical significance was however not achieved (p=0.38), mainly due to the small sample size. The investiagtors hypothesize that in PC-DLD a higher intensity (i.e., starting with a medium dose of prednisolone) will be more effective than a lower dose intensity (i.e., starting with a low dose of prednisolone) of glucocorticoids in effecting a radiologic response at six weeks.
