Retrospective 60 ICU patients in Iran, showing that lower levels of vitamin D, magnesium, and zinc were significantly associated with higher APACHE scores (P = 0.001, 0.028, and <0.001, respectively) and higher lung involvement (P = 0.002, 0.045, and <0.001, respectively).

Objectives: This study aimed to compare the serum level of micronutrients with normal amounts, and assess
their association with the severity of disease and inflammatory cytokines in patients with coronavirus disease 2019 (COVID-19).
Methods: The present cross-sectional study included 60 patients admitted to the intensive care unit with
COVID-19. We recorded data on demographic characteristics, anthropometric information, and medical history. Serum levels of inflammatory markers (erythrocyte sedimentation rate, C-reactive protein, interferongamma, tumor necrosis factor-alpha, interleukin-6), vitamins (A, B9, B12, C, D, E), and minerals (magnesium,
zinc, iron) were measured. A radiologist assessed the severity of lung involvement according to patient computed tomography scans. The severity of illness was evaluated with the Acute Physiologic Assessment and
Chronic Health Evaluation (APACHE) score, oxygen saturation, and body temperature. Independent associations among the serum levels of micronutrients with the severity of COVID-19 were measured.
Results: Median patient age was 53.50 years (interquartile range, 12.75 years). Except for vitamin A and zinc,
serum levels of other micronutrients were lower than the minimum normal. Patients with APACHE score
25 had a higher body mass index (P = 0.044), body temperature (P = 0.003), erythrocyte sedimentation rate
(P = 0.008), C-reactive protein (P = 0.003), and lower oxygen saturation (P = 0.005), serum levels of vitamin D
(P = < 0.001), and zinc (P = < 0.001) compared with patients with APACHE score <25. We found that lower
serum levels of vitamin D, magnesium, and zinc were significantly and independently associated with higher
APACHE scores (P = 0.001, 0.028, and < 0.001, respectively) and higher lung involvement (P = 0.002, 0.045,
and < 0.001, respectively).
Conclusions: Lower serum levels of vitamin D, zinc, and magnesium were involved in severe COVID-19.
