The relation between serum D-dimer, ferritin and vitamin D levels, and dysgeusia symptoms, in patients with coronavirus disease 2019

Objective This study aimed to evaluate the association between serum D-dimer, ferritin and vitamin D levels, and dysgeusia symptoms, in patients with coronavirus disease 2019. Methods The present study was conducted with the medical records of 300 patients positive for coronavirus disease 2019, hospitalised between 28 March and 15 August 2020. The patients were divided into two groups regarding the presence or absence of dysgeusia symptoms. Results Fever and sore throat rates, and the mean D-dimer level, were considerably higher in the dysgeusia group than in the non-dysgeusia group (32.1 vs 21.6 per cent, p = 0.04; 43.6 vs 20.7 per cent, p < 0.001; and 0.54 +/- 0.32 vs 0.49 +/- 0.51 mg/l FEU, p = 0.008, respectively). The mean age was significantly lower in the dysgeusia group than in the non-dysgeusia group (42.83 +/- 12.31 vs 50.51 +/- 13.67 years, p < 0.001). Conclusion Younger age, fever and shortness of breath could be observed in patients with dysgeusia symptoms. In addition, the D-dimer level was significantly higher in the dysgeusia group.
