There was no significant difference between continuous and intermittent irradiation with 222 nm UVC with regards to SARS-CoV-2 inactivation. Moreover, 222 nm UVC inactivates SARS-CoV-2 in a fluence-dependent manner. The efficacy of 222-nm UVC irradiation in reducing the contamination of SARS-CoV-2 needs to be further evaluated in a real-world setting.

Cytokine storm described in patients after allogeneic haematopoietic stem cell transplantation (alloHSCT) is associated with the appearance of CD14+HLADR - in the blood. To study the role of CD14+HLADR - cells 223 patients after alloHSCT followed from 1month to 15years. The methods used included flow cytometry for blood cells profiling, nucleic acid tests for viral reactivation, and physician care according to the Polish and international guidelines. We found that CD14+HLADR - peak values determined during the first 60 post-transplant days were higher in the patients who died than in those who survived in this time interval (mean±SEM 3.78±0.67% vs 2.38±0.65%, p<0.001). Receiver operating characteristic (ROC) analysis showed that CD14+HLADR - cells level in the blood at cut-off point at 0.71% discriminated the patients as to survival; the patients above the threshold had poorer survival (Kaplan-Meier curve covering 15-year observation) than those below (0.19 vs 0.46, p<0.001). Infections prevailed other causes of death in the high blood CD14+HLADR - group (0.61 vs 0.38, p=0.057). ROC analysi
