Abstract

Background

This study aims to investigate whether fetuin A deficiency predicts the prognosis of COVID-19 disease in kidney transplant recipients (KTRs).

Method

The study was conducted on 35 hospitalized KTRs with COVID-19 pneumonia between November 2020 and June 2021. Serums were collected for fetuin-A measurement at admission and after six months of follow-up. The demographic and laboratory data of the patients were recorded and analyzed with the appropriate statistical method.

Results

A total of 35 KTRs, 23 of which (65.7%) were men, were included in the study. The mean age of the patients was 51.6 ± 14.0 years. Seventeen (48.6%) patients had severe disease criteria and required intensive care (ICU) support. Biopsy-proven acute rejection developed in 6 (17.1%) patients in the follow-up. At admission, the median fetuin-A value was 173.5 mcg/mL (143.5-199.25) in the moderate disease group and 126.0 mcg/mL (89.4-165.5) in the severe patient group (p = 0.005). While the Median fetuin-A value at the time of diagnosis was 173.5 mcg/mL (143.5-199.25), and in the 6th month was 208 mcg/mL [184-229] (p<0.001). By ROC analysis, the effect of serum fetuin-A level in predicting the severity of COVID-19 disease was significant (AUC: 0.771, p = 0.006, 95% CI: 0.615-0.927). When serum fetuin-A cut-off value was taken as 138 mcg/mL to determine disease severity, it was shown to have 83.3% sensitivity and 64.7% specificity.

Conclusions

Serum fetuin-A level can predict disease severity in kidney transplant recipients in the presence of active COVID-19 disease.
