There is limited information about the connection between metabolic syndrome (MetS) and the outcome of COVID-19 patients.
•
The hospitalized COVID-19 cases with MetS undergoing intensive cares are more likely to have severe clinical course.
•
The need for prioritizing screening, detection, and aggressive therapy in MetS patients must be considered.
•
MetS is associated with increased risk of severe complications and mortality among COVID-19 ICU-admitted patients.
Abstract
Background and aims
Given the limited information describing the connection between metabolic syndrome (MetS) and Coronavirus Disease 2019 (COVID-19), we aimed to assess the impact of MetS on morbidity and mortality among COVID-19 patients.
Methods
This retrospective cohort study was performed from 1st April to May 3, 2020 on 157 ICU-admitted COVID-19 patients in Shahid Modarres Hospital in Tehran, Iran. Patients’ clinical, laboratory and radiological findings, and subsequent complications, were collected and compared between MetS and non-MetS groups.
Results
74 of all cases had MetS. Among the MetS components, waist circumference (p-value = 0.006 for men; p-value<0.0001 for women), Triglycerides (p-value = 0.002), and Fasting Blood Sugar (p-value = 0.007) were significantly higher in MetS group; with no statistical difference found in HDL levels (p-value = 0.21 for men; p-value = 0.13 for women), systolic blood pressure(p-value = 0.07), and diastolic blood pressure (p-value = 0.18) between two groups. Length of ICU admission (p-value = 0.009), the need for invasive mechanical ventilation (p-value = 0.0001), respiratory failure (p-value = 0.0008), and pressure ulcers (p-value = 0.02) were observed significantly more in MetS group. The Odds Ratio (OR) of mortality with 0(OR = 0.3660), 1(OR = 0.5155), 2(OR = 0.5397), 3(OR = 1.9511), 4(OR = 5.7018), and 5(OR = 8.3740) MetS components showed an increased mortality risk as the components’ count increased. The patient with BMI>40 (OR = 6.9368) had more odds of fatality comparing to those with BMI>35 (OR = 4.0690) and BMI>30 (OR = 2.5287). Furthermore, the waist circumference (OR = 8.31; p-value<0.0001) and fasting blood sugar (OR = 2.4588; p-value = 0.0245) were obtained by multivariate logistic regression as independent prognostic factors for mortality.
Conclusion
The findings suggest a strong relationship between having MetS and increased risk of severe complications and mortality among COVID-19 ICU-admitted patients.
