Abstract
OBJECTIVE: This systematic review and meta-analysis aimed to evaluate the association between the prealbumin and severity and mortality in COVID-19. MATERIALS AND METHODS: We performed a systematic literature search from PubMed, Embase, and Scopus databases up until 2 February 2021. The primary outcome was the poor outcome, a composite of mortality and severity. Severe COVID-19 was defined as COVID-19 that fulfill the criteria for severe pneumonia or patients with acute respiratory distress syndrome/disease progression/need for intensive care unit or mechanical ventilation. The effect estimates were a mean difference between patients with and without a poor outcome in mg/dL and odds ratio (OR) per 1 mg/dL decrease in prealbumin level. The effect estimates were reported with their 95% confidence interval (95% CI). RESULTS: Nine studies comprising of 2104 patients were included in this systematic review and meta-analysis. Patients with poor outcome have lower prealbumin level (mean difference -71.48 mg/dL [95% CI -93.74, -49.22], p<0.001; I2: 85.9%). Every 1 mg/dL decrease in prealbumin level was associated with 1% increase in poor outcome (OR 0.992 [0.987, 0.997], p=0.004, I2: 81.7%). Meta-regression analysis showed that the association between the prealbumin level and poor outcome varies with gender (male) (coefficient: 3.50, R2: 100%, p<0.001), but not age, diabetes, hypertension, and chronic kidney disease. CONCLUSIONS: Low serum prealbumin was associated with poor outcomes in patients with COVID-19.
