inclusion criteria: adult sari patients with 2019-ncov infection confirmed by pcr; absolute value of lymphocytes < 0. 6x 109/l; severe respiratory failure within 48 hours and requires admission to icu. (severe respiratory failure was defined as pao2/fio2 < 200 mmhg and was supported by positive pressure mechanical ventilation (including non-invasive and invasive mechanical ventilation, peep>=5cmh2o))

(13- cis -retinoic acid ) can be given in the form of aerosol to avoid these systemic side effects. a clinical trial conducted on 148 subject from 5 university hospitals to evaluate the possibility of retinoids in the treatment of emphysema. the patients, were randomized to receive 13-cis retinoic acid (1 mg/kg/day, daily or atra at either low dose (1 mg/kg/day for 4 days/wk) or high dose (2 mg/kg/day for 4 days/wk), placebo for six months, followed by a three-month crossover phase. then, they were observed for an additional nine months before the final evaluation. in the trial, retinoids(13 cis retinoic acid ) were proven to be safe as the drug-related aes were generally mild[188]. a study reported that the application of aerosolized ra system led to a rise of ra levels in lung, but not plasma. or liver. in lung concentration and levels of retinol, retinyl palmitate and retinyl stearate also showed to be unchanged [189] a study on rabbits demonstrated that 13 cis retinoic acid can be given in the form of aerosol without serious side effects in this study repeated elevated doses of 13 cis retinoic acid by inhalation caused moderate loss of body weight, but microscopic examination of ten tissues including oesophagus and lung did not found any significant inhalation-induced injury or damage therefore aerosolized 13 cis retinoic acid might provide sufficient therapy to the target cells in lung for efficacy while avoiding systemic toxicity © 2000 cancer research campaign[190]
