It is shown a better prognostic relationship between PLR and NLR low values and OS that is statistically significant in mCPRC patients treated with abiraterone. Furthermore, it was not shown a relation between PLR and NLR values and PSA response.

BACKGROUND The novel coronavirus 2019 (COVID-19) pandemic has dramatically transformed the care of the liver transplant patient. In patients who are immunosuppressed and with multiple comorbidities, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection has been associated with increased severity and mortality. The main objective of this report is to communicate our experience in the therapeutic management of SARS-CoV-2 infection in 3 liver transplant patients. Secondly, we stress the management and investigation of the contagious spreading into a liver transplant ward. CASE SUMMARY The patients were two women (aged 61 years and 62 years) and one man (aged 68 years), all of them having recently received a liver transplant. All three patients required intensive care unit admission and invasive mechanical ventilation. Two of them progressed severely until death. The other one, who received tocilizumab, had a good recovery. In the outbreak, the wife of one of the patients and four healthcare professionals involved in their care were also infected. CONCLUSION We illustrate in detail the evolution of a nosocomial COVID-19 outbreak in a liver transplant ward. We believe that these findings will contribute to a better understanding of the natural history of the disease and will improve the treatment of the liver transplant patient with COVID-19.

Background: We aimed to determine the impact of tocilizumab use in severe COVID-19 pneumonia mortality. Methods: We performed a multicentre retrospective cohort study in 18 tertiary hospitals in Spain, from March to April 2020. Consecutive patients admitted with severe COVID-19 treated with tocilizumab were compared to patients not treated with tocilizumab, adjusting by Inverse Probability of the Treatment Weights (IPTW). Tocilizumab effect in patients receiving steroids during the 48h following inclusion was analyzed. Results: During the study period, 506 patients with severe COVID-19 fulfilled inclusion criteria. Among them, 268 were treated with tocilizumab and 238 patients were not. Median time to tocilizumab treatment from onset of symptoms was 11 days (IQR 8-14). Global mortality was 23.7%. Mortality was lower in patients treated with tocilizumab than in controls (16.8% versus 31.5%, HR 0.514 [95CI 0.355-0.744], p<0.001; weighted HR 0.741 [95CI 0.619-0.887], p=0.001). Tocilizumab treatment reduced mortality by 14.7% relative to no tocilizumab treatment (RRR 46.7%). We calculated a number necessary to treat of 7. Among patients treated with steroids, mortality was lower in patients treated with tocilizumab than in those treated with steroids alone (10.9% versus 40.2%, HR 0.511 [95CI 0.352-0.741], p=0.036; weighted HR 0.6 [95CI 0.449-0.804], p<0.001) (Interaction p=0.094). Conclusions: These results show that survival of patients with severe COVID-19 is higher in patients treated with tocilizumab than in those not treated, and that tocilizumab effect adds to that of steroids administered to non-intubated cases with COVID-19 during the first 48 hours of presenting with respiratory failure despite of oxygen therapy. Randomised controlled studies are needed to confirm these results.

On March 19 World Health Organization declare the pandemic situation by outbreak coronavirus disease 2019 in the world. The pressure on the health care system has been very high in several countries. Spanish National Transplant Organization (ONT) have made many efforts in maintaining transplantation activity. Although the impact of the pandemic on organ activity has been analysed, to date, less data exist regarding the impact on tissue activity. The aim of this study has been the evaluation of the possible impact on the procurement, processing and distribution of tissues during the peak period of the pandemic COVID-19 in Spain. For this study, a multicentre analysis has been made with a survey of the tissue banks in Spain, during the period March 1 to April 30, 2020. Our data suggest that the impact of coronavirus in Spain has affected dramatically tissue donation but with a moderate effect on stored tissues such as bone, valves, vessels or skin. Tissue banks should prepare if future next pandemic waves surges so that tissue provision is guaranteed both in urgent and elective surgeries.
