Obesity

Metabolic conditions and COVID-19
Identifying metabolic risk is key in optimizing patient outcomes should they become infected with COVID-19
A recent study published in the journal Diabetes Care links metabolic syndrome and severe outcomes from COVID-19, noting significant increases in intensive care admissions, ventilation, acute respiratory distress syndrome (ARDS), and death among patients with metabolic syndrome vs those without metabolic syndrome1

Metabolic syndrome is defined by the National Heart, Lung, and Blood Institute as a group of factors increasing risk for heart disease, diabetes, stroke, and other health problems. Patients are said to have metabolic syndrome if they have 3 or more of the following conditions2:

Obesity and COVID-19
New data from the CDC confirms that obesity increases heightened risks from COVID-19. As well, adult obesity rates are rising nationwide with notable racial and ethnic disparities.
12 states had adult obesity rates of over 35% | 34 states and the District of Columbia have obesity rates of over 35% |
15 states have obesity rates of over 35% | 6 states have obesity rates of over 35% |
As obesity worsens outcomes from COVID-193, including chances of hospitalization and death, Quest’s Metabolic Risk panel can help you identify individuals most at risk for severe outcomes.
Diabetes and increased risks for COVID-19
The risks of severe outcomes for patients with diabetes who contract COVID-19 are well noted. The CDC states that type 2 diabetes increases the risk of severe illness from COVID-19, and that type 1 or gestational diabetes may also increase the risk.4
The International Diabetes Federation (IDF) notes the difficulty in treating viral respiratory infections such as COVID-19 due to fluctuations in blood glucose levels and possible diabetes complications. Two potential reasons for the severity of COVID-19 in patients with diabetes may be tied to compromised immune systems and the possibility that the virus may thrive in elevated blood glucose.5
Additionally, a recent letter in the New England Journal of Medicine notes that the inflammatory response associated with SARS-CoV-2 may impact preexisting diabetes risk.6

Respiratory viral infections and heart health
Cardiovascular disease (CVD) and other pre-existing conditions increase risk from respiratory viral infections such as COVID-19 and seasonal flu.
Quest can help you identify patients at increased cardiovascular risk.

12 states had adult obesity rates of over 35% in 2019 (up from 9 states in 2018 and 6 states in 2017) | 34 states and the District of Columbia have obesity rates of over 35% among African-American adults |
15 states have obesity rates of over 35% among Hispanic adults | 6 states have obesity rates of over 35% among non-Hispanic white adults |

Patients with diabetes are also at high risk from the flu
Complications from the flu can also be serious for people with type 1, type 2, or gestational diabetes. Some flurelated complications from diabetes include pneumonia, bronchitis, sinus infections, and ear infections. Changes in appetite related to flu complications can also result in swings in glucose levels. |

Management of diabetes and glycated hemoglobin testing
![]() | While guidelines suggest regular monitoring of glycated hemoglobin (HbA1c) with a frequency of 2 to 4 times a year, a recent study by Quest researchers8 indicated that the COVID-19 pandemic and its related quarantines may have compromised diabetes management. Compared to the previous 60 weeks, researchers noted that testing was down by as much as 66% during the first 8 weeks of March and April 2020. The researchers concluded that the drop in testing frequency might lead to increases in higher blood pressure and hyperlipidemia, as well as a higher risk of complications such as cardiovascular disease, microvascular complications, and myocardial infarction.8 |

Patients with diabetes are at an increased risk for heart disease
The American Heart Association notes that people with diabetes are 2 to 4 times more likely to die from heart disease than people without diabetes—68% of people aged 65 or older who have diabetes die from heart disease and 16% from stroke. Patients with diabetes may have conditions that increase the risk for heart disease, such as hypertension, unhealthy cholesterol levels, obesity (which contributes to insulin resistance), and fluctuations in blood sugar levels.9

Ensuring your patients with diabetes or prediabetes monitor their glycated hemoglobin at recommended frequency can help them better manage their insulin.
Identifying insulin resistance for early intervention
Patients at risk for insulin resistance (IR) may be difficult to diagnose without testing. Patients with normal glucose and HbA1c may be at risk10 as may individuals with the following clinical features:
|
|
|
Insulin resistance is estimated to affect more than 60 million Americans.11 Testing for IR can help patients take action to prevent or delay the course of their prediabetes/diabetes.12

How the laboratory can help
Quest Diagnostics and Cleveland HeartLab® provides tests to assist in the assessment and care of patients with underlying metabolic risk who are at increased risk for severe outcomes from COVID-19. |
|
aIf ordering through Cleveland HeartLab (CHL) use the following test order codes: Insulin Resistance Panel with Score (1388), Hemoglobin A1C (HbA1c) (C145)
bPanel components may be ordered separately. For CHL panel components: Insulin (C146), C-Peptide (C136). For Quest panel components: Insulin, Intact, LC/MS/MS (93103), C-Peptide (372)
