Abstract:


Background: In Covid-19 infection, leukopenia, inflammation, and elevated liver enzymes are found in most patients. Also, vitamin D deficiency attenuates the immune system and predisposes a person to being more susceptible to infection. In this context, we aimed to evaluate vitamin D, electrolytes, complete blood count, liver enzymes, urea, creatinine, albumin, CRP and ESR levels in patients with Covid-19.

Methods: We conducted a cross-sectional study on 118 patients with Covid-19 who were hospitalized from 2020/2/19 to 2020/4/3 in ICU. Serum levels of electrolytes, liver enzymes, blood factors, urea, creatinine, CRP and ESR, as well as anthropometric parameters and serum vitamin D concentration, were measured.

Results: A total of 118 patients (80 male and 38 female) were enrolled in the study (65.05±15.75 years). Only 5.08% of patients had no risk factors and 55.9% had ≥ 2 risk factors. Diabetes (44.1%) and obesity (23.7%) were more common among patients. Laboratory findings showed that 80.50% of patients had hyponatremia, but other electrolytes including K, Mg, Ca and P were normal in the majority of participants as well as CBC, Cr, Urea, Alb, ALT and ALKP. The AST concentration increased in most patients (66.94%). All patients had high levels of inflammatory factors such as CRP and ESR. The mean of 25-hydroxy-vitamin D levels in participants (25.95 ± 14.56 ng/mL) was lower than its levels in the general population. However, it was not statistically significant (P= 0.88). A significant negative correlation was found between vitamin D and ALT (P= 0.02, -0.21) as well as vitamin D and CRP (P= 0.05, -0.17).

Conclusion: Due to the regulatory role of vitamin D in the immune system and low levels of vitamin D in Covid-19 infected patients, the evaluation of vitamin D levels and prescribed supplements, if necessary, is suggested.
