As US outbreaks surge, a new government study shows that nearly 40% of people who have died with Covid-19 had diabetes.
Among deaths of those under 65, half had the chronic condition. The US Centers for Disease Control and Prevention analyzed more than 10,000 deaths in 15 states and New York City from February to May.
Jonathan Wortham, a CDC epidemiologist who led the study, called the findings “extremely striking,” with serious implications for those with diabetes and their loved ones.
Ten states, including California, Arizona and Michigan, said they weren’t yet reporting diabetes and other underlying conditions, and the rest did not respond - rendering an incomplete picture for policymakers and clinicians struggling to protect those most at-risk.
America’s mortality rates from diabetes have been climbing since 2009 and exceed most other industrialized nations. Blacks and Latinos suffer from diabetes at higher rates than whites and have disproportionately suffered from Covid-19.
“Diabetes was already a slow-moving pandemic. Now Covid-19 has crashed through like a fast-moving wave,” said Elbert Huang, a professor of medicine and director of the University of Chicago’s Center for Chronic Disease Research and Policy.
The high price of insulin has also forced some people to keep working - risking virus exposure - to afford the essential medicine. And as the country grapples with an economic crisis, millions of Americans have lost their jobs and their employer-sponsored health insurance.
Top health officials should have done more to emphasize the threat to people with diabetes and assuage their fears of hospital visits, he said, while also focusing more on helping patients manage their condition at home.
Policymakers had ample warning that Covid-19 posed a high risk for diabetes patients. In 2003, during the coronavirus outbreak known as SARS, or Severe Acute Respiratory Syndrome, more than 20% of people who died had diabetes.
Doctors warn that the coronavirus pandemic may indirectly lead to a spike in diabetes-related complications - more emergency-room visits, amputations, vision loss, kidney disease and dialysis.
‘One big puzzle’
Researchers have scrambled for months to unravel the connections between diabetes and the coronavirus, uncovering an array of vulnerabilities.
The virus targets the heart, lung and kidneys, organs already weakened in many diabetes patients. Covid-19 also kills more people who are elderly, obese or have high blood pressure, many of whom also have diabetes, studies show.
On the microscopic level, high glucose and lipid counts in diabetes patients can trigger a “cytokine storm,” when the immune system overreacts, attacking the body. Damaged endothelial cells, which provide a protective lining in blood vessels, can lead to inflammation as white blood cells rush to attack the virus and may cause lethal clots to form, emerging research suggests.
“It’s all one big puzzle,” said Yale’s Dela Cruz. “It’s all interrelated.”
Many of their vulnerabilities can be traced to high blood sugar, which can weaken the immune system or damage vital organs. Covid-19 appears not only to thrive in a high-sugar environment but to exacerbate it. Recent evidence suggests the virus may trigger new cases of diabetes.
David Thrasher, a pulmonologist in Montgomery, Alabama, said up to half of Covid-19 patients in his local hospital ICU have diabetes. “They are often my most challenging patients,” he said, and the immune system response may be a big reason why.
‘Diabetes belt’
The pandemic has ripped through several southern states with some of the nation’s highest diabetes rates. Nearly 40% of Covid-19 deaths were people with diabetes in Alabama, Louisiana, Mississippi, North Carolina, South Carolina and West Virginia. Much of this area lies within what the CDC calls the “diabetes belt.”
Alabama has the highest percentage of adults with diabetes at 13.2%, or more than 550,000 people, CDC data show. Diabetes patients accounted for 38% of the state’s Covid-related deaths through June, officials said. Karen Landers, Alabama’s assistant state health officer, said she is particularly heartbroken at the deaths of diabetes patients in their 30s and 40s.
Sarah Hunter Frazer, a nurse practitioner at the Medical Outreach Ministries clinic for low-income residents in Montgomery, Alabama, said diabetes is common among her Covid-19 patients. With clinic visits on hold, she stays in touch by phone or video chat. If a problem persists, she insists on an outdoors, face-to-face meeting. “We meet them under a shade tree behind the clinic,” Frazer said.
In similar fashion, doctors at the University of North Carolina stepped up their use of telemedicine to reach at-risk rural patients.
‘Under control’
Many diabetes patients with severe or deadly cases of Covid-19 were in good health before contracting the virus.
Clark Osojnicki, 56, of Stillwater, Minnesota, had heard early warnings about the risks of the coronavirus for people with diabetes, said his wife, Kris Osojnicki. But the couple didn’t think the admonitions applied to him because his glucose levels were in a healthy range.
“He was incredibly active,” she said.
On a Sunday in mid-March, Osojnicki jogged alongside his border collie, Sonic, on an agility course for dogs inside a suburban Minneapolis gym. Three days later, Osojnicki developed a fever, then body aches, a cough and shortness of breath. He was soon in the hospital, on a ventilator. Clark, a financial systems analyst, died April 6 from a blood clot in the lungs.
Osojnicki is among 255 recorded deaths in Minnesota of people with Covid-19 and diabetes mentioned on their death certificate as of mid-July, according to state data. The records describe people who died as young as 34.
Working for Insulin
For years, the skyrocketing cost of insulin has fueled much of the national outrage over drug prices. Early in the pandemic, the American Diabetes Association asked states to eliminate out-of-pocket costs for insulin and other glucose-lowering medications through state-regulated insurance plans.
But no state has fully followed that advice, the ADA said. Vermont suspended deductibles for preventive medications, like insulin, starting in July. Other states ordered insurers to make prescription refills more available but didn’t address cost.
