The presence of preformed HLA DSA in transplanted patients with a negative cytotoxicity crossmatch is associated with a lower allograft survival. The detection of anti-HLA with no DSA has no influence in the graft outcome. Finally, there were no demonstrable effects of mean fluorescence intensity (MFI) values >1500 on graft survival.

J o u r n a l P r e -p r o o f SPECIAL ARTICLE Recommendations on the management of the SARS-Co V-2 coronavirus pandemic (Covid-19) in kidney transplant patients Recomendaciones en el manejo de la pandemia por coronavirus SARS-CoV-2 (Covid-19) en pacientes con trasplante renal SUMMARY The SARS-CoV-2 (Covid-19) coronavirus pandemic is evolving very quickly and means a special risk for both immunosuppressed and comorbid patients. Knowledge about this growing infection is also increasing although many uncertainties remain, especially in the kidney transplant population. This manuscript presents a proposal for action with general and specific recommendations to protect and prevent infection in this vulnerable population such as kidney transplant recipients.RESUMEN La pandemia de coronavirus del SARS-CoV-2 (Covid-19) está evolucionando muy rápidamente y significa un riesgo especial para pacientes inmunosuprimidos y con comorbilidad..

According to our results, patients with preformed or de novo anti-HLA-DSA showed the highest likelihood to suffer rejection episodes. Transplantation with preformed anti-HLA-DSA should be avoided, and an early detection of de novo HLA antibodies is important to treat patients before damage occurs in the graft.
