Fourteen patients (67%) had an absolute lymphocyte count of less than 1000 cells/μL. Liver function tests were abnormal in 8 patients (38%) at admission (Table 1).
Mechanical ventilation was initiated in 15 patients (71%) (Table 2). Acute respiratory distress syndrome (ARDS) was observed in 15 of 15 patients (100%) requiring mechanical ventilation and 8 of 15 (53%) developed severe ARDS by 72 hours.
