Does Monocyte Chemoattractant Protein-1 Levels Determine the Prognosis of Covid-19 Disease in Kidney Transplant Recipients?

BACKGROUND: In the normal population, a high monocyte chemoattractant protein (MCP-1) level is an important biomarker for the progression of COVID-19. This study investigated whether MCP-1 level can determine the disease prognosis in kidney transplant (KT) patients with COVID-19. METHODS: A total of 89 patients, including 49 KT patients (group 1) diagnosed with COVID-19 who required hospitalization, and 40 KT patients who did not have COVID-19 disease (group 2), were included. Demographic characteristics and laboratory results of the patients were recorded. The serum reserved for MCP-1 was stored at -80°C and studied blindly by a single microbiologist at the end of the study. RESULTS: While the mean age of the patients was 51.0 years (40.0-59.50) in group 1, it was 48.0 years (40.75-54.75) in group 2 (P > .05). In terms of the female sex, it was 36 (73.5%) and 27 (67.5%) in group 1 and group 2, respectively (P > .05). Similarly, there was no significant difference between the 2 groups regarding primary disease and basal graft function (P > .05). There was a statistically significant difference in inflammation indicators in group 1 compared with group 2 (P < .05). A correlation was found between inflammation indicators and COVID-19 (P < .05). However, no significant correlation was detected between COVID-19 disease and MCP-1 levels in both groups (P > .05). Also, according to basal MCP-1 levels, we did not find a significant difference between survival and nonsurvival patients (164.0 pg/mL [146.0-202.0] vs 156.0 pg/mL [143.0-173.0], respectively (P > .05). CONCLUSION: Monocyte chemoattractant protein, an indicator of inflammation, was not found to predict the prognosis of COVID-19 disease in kidney recipients.

Can fetuin-A deficiency predict the severity of COVID-19 disease in kidney transplant recipients?

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.

Conclusion MCP-1, an indicator of inflammation, was not found to be a predictor of prognosis of COVID-19 disease in kidney recipients.
