BACKGROUND: Tocilizumab was studied to reduce cytokine syndrome in patients with severe COVID-19 pneumonia in solid organ transplant (SOT) recipients with conflicting results. We aim to study the early use of tocilizumab in SOT with COVID-19 pneumonia on low flow oxygen. METHODS: This is a retrospective cohort study that was conducted in two transplant centers in Saudi Arabia among 46 SOT with COVID-19 comparing 21 patients who received tocilizumab to 25 patients who received standard of care. Their clinical characteristics and outcomes were described. RESULTS: Compared to patients who received standard of care, patients in the tocilizumab group were older (60.2 ± 12.8 vs. 48.6 ± 12.3, p = .003), had higher ferritin (862.1 ± 919.1 vs. 414 ± 447.3, p = .025) and C-reactive protein (CRP) (85 ± 83.1 vs. 42.9 ± 57.3, p = .012). More patients in the tocilizumab group required high flow oxygen (38.1% vs. 8.0%, p = .028) compared to patients on standard of care. There were no differences in mortality or mechanical ventilation requirement. Hospital stay was significantly shorter in the tocilizumab group than the standard of care group (9.6 ± 7.4 vs. 20.7 ± 11.7, p < .001). CONCLUSIONS: Early use of tocilizumab in SOT was associated with a shorter hospital stay. There was no difference in mortality rate and the requirement for mechanical ventilation in both groups.

Immunocompromised patients who have a severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection pose many clinical and public health challenges. We describe the case of a hematopoietic stem cell transplantation patient with lymphoma who had a protracted illness requiring three consecutive hospital admissions. Whole genome sequencing confirmed two different SARS-CoV-2 clades. Clinical management issues and the unanswered questions arising from this case are discussed.
