More Than 200,000 Americans Have Lupus
THURSDAY, Jan. 21, 2021 (HealthDay News) – Just over 200,000 Americans have lupus, an autoimmune disease, and minority women are most at risk, according to a new study.
This is the first estimate of the extent of the disease in the United States. The number is close to reclassifying lupus as a rare disease, defined as a disease affecting 200,000 Americans or less, the researchers said.
“Our study potentially redefines systemic lupus erythematosus as a rare disease in the United States and lays the foundation on which we must focus our efforts to reduce the burden of this disease on Americans,” said Dr. Peter Izmirly, senior investigator in a press release. of NYU Langone Health in New York. He is a rheumatologist and associate professor of medicine in the health system.
In lupus (systemic lupus erythematosus), the immune system mistakenly attacks its own healthy tissue, especially the joints and skin. The disease can be fatal and often causes debilitating episodes of fatigue and pain that prevent nearly half of adult patients from working.
Previous estimates of lupus were larger but unverified.
In this study, researchers analyzed the records of 5,417 adults and children diagnosed with lupus since 2002 across all US state registries for the disease, as well as the Indian Native Health Service. Then they calculated the number of people with lupus for each gender and ethnicity and applied those numbers to the demographics from the 2018 census.
They concluded that out of 100,000 people nationwide, 72.8 had lupus, for a total of 204,295 people out of a population of 330 million.
The study found that nine times more women than men have lupus, and the highest rates among Native American / Alaska Native women, at 270.6 per 100,000.
Black women had the second highest rate (230.9 per 100,000), followed by Hispanic women at 120.7 per 100,000.
Similar racial disparities were seen among men with lupus, with American Indian / Alaska Natives having the highest number (53.8 per 100,000), followed by black men at 26.7 per 100 000.
