Background. The number of recipients living with a kidney transplant continues to grow. Parenchymal organ recipients receiving chronic immunosuppressive therapy are at increased risk of severe SARS-CoV-2 [1, 2]. This requires a dynamic assessment of mortality among kidney transplant recipients with SARS-CoV-2.
Objective. Comparative assesmrnt of the data on mortality and immunosuppressive therapy in kidney transplant recipients (KTR) with SARS-CoV-2 who lived for more than a year after kidney allotransplantation (KAT) and were treated in various clinical centers in Moscow from 02/01/2020 to 09/30/2020 according to the UMIAS data, with a systematic analysis of published studies on the same topic for a similar period of time.
Material and methods. The electronic MEDLINE, Scopus and the Cochrane Central Register of Controlled Trials databases were searched for eligible studies. All prospective and retrospective mortality studies with ≥50 KTR patients with SARS-CoV-2 were considered eligible. A meta-analysis of proportions was performed using the Freeman-Tukey transform to calculate the weighted summary proportion under the fixed and random effects model. Of the total number of 379 studies found, 13 were included in the systematic review and meta-analysis, incl. and ours, with a total of 3333 KTRs with SARS-CoV-2.
Results. In the survival analysis, the proportion of deaths averaged 19.82% (fixed model) and 19.30% (random model). The mortality rate of KTRs with SARS-CoV-2 recorded in UMIAS turned out to be almost the same (19.55%). A positive effect of tacrolimus therapy on survival of KTRs with SARS-CoV-2 has been identified. Tacrolimus was used more frequently in survivors (Me 0.7890, 95% CI 0.5828–0.9200, IQR 0.5828–0.9200) compared to non-survivors (Me 0.7860, 95% CI 0.3800–0, 8625, IQR 0.3800–0.8295), P=0.0195. Therapy with glucocorticosteroids was more often carried out among the deceased, however, the data obtained in the meta-analysis were not reliable (P = 0.25). Meta-analysis data were characterized by low heterogeneity (I2 -75.42%; P<0.0001). Errors in the selection of publications according to the Egger and Begg test were not identified.
Conclusion. This meta-analysis suggests that mortality among KTRs with SARS-CoV-2 hospitalized and treated in various clinical centers in Moscow, according to UMIAS from 02/01/2020 to 09/30/2020, did not differ from the population among the same patients for the same period time. A positive effect of tacrolimus therapy on the survival of KTRs with SARS-CoV-2 was revealed.
