Eligibility

Inclusion criteria

Inclusion criteria: 1. Adult patients with RT-PCR proven COVID-19 with moderate to severe pneumonia with fewer than 14 days of symptom onset that warranted hospitalization and currently receiving standard medication for COVID-19 at appropriate doses which would include,among others, antivirals, corticosteroids, or anti-IL-6 tocilizumab.and 2. moderate to severe dyspnoea, respiratory frequency equal to or greater than 30/min, oxygen saturation without supplemental O2 supply SpO2 94% or less, PaO2/FiO2 ratio or PaFiO2 ratio between 200 to 300 or SpO2/FiO2 ratio 315 or less if PaO2 is not available and/or 3. laboratory abnormalities such as C-reactive protein >100 mg/L or D-dimer >1000 ng/ml or IL-6 >50 IU or suspected cytokine release syndrome

Exclusion criteria

Exclusion criteria: 1. Patients on ventilators (invasive/non invasive) 2. Prior lobectomy or pneumonectomy 3. Prior thoracic radiotherapy resulting in a maximum lung dose of 100 cGy or higher within 14 days of enrollment 4. Prior chemotherapy or other systemic therapy with potential for pulmonary toxicity or radio sensitization within 14 days or 5 half-lives, whichever is greater, of enrollment, e.g., bleomycin, gemcitabine 5. Prior cancer immunotherapy with an immune checkpoint inhibitor within 60 days of enrollment 6. Severe pre-existing heart disease, e.g., New York Heart Association (NYHA) functional class 3 (or higher) congestive heart failure 7. History of bone marrow or solid organ transplantation 8. Known history of autoimmune collagen vascular disease, e.g.,scleroderma 9. Known hereditary syndrome with increased sensitivity to ionizing radiation, e.g., ataxia-telangiectasia or Fanconi anemia 10. Pregnancy 11.

Design outcomes

Primary

MeasureTime frame
The primary end-point will be to evaluate the efficacy of low-dose pulmonary irradiation as an adjunctive treatment in interstitial pneumonia in patients with COVID-19 by improving the Spo2 levels 48-72h after treatment with respect to baseline pre-irradiation measurementTimepoint: 6 hours,day 1,2,3,4,7

Secondary

MeasureTime frame
The secondary objectives include assessing the safety of bilateral pulmonary LDRT using a Linear acclerator,evaluating theimprovement of the radiological image, overall mortality rate at 28 days after irradiation and measuring the level of CRP, IL-6, D-dimer, Total Lymphocyte count, Absolute neutrophil count and Neutrophil to Lymphocyte ratio and documenting the incidence of adverse events and their grade if applicableTimepoint: Blood tests on Days 1,4,7,14,30 Baseline Chest X-ray and on Days 3,7 CT chest Baseline and Day 14
