The CCP antibody test helps to diagnose RA and can be useful in identifying people with a more rapidly erosive form of the disease. RA is a chronic, systemic autoimmune disease that causes inflammation, pain, stiffness, and destructive changes in the hands, feet, and other joints throughout the body.
As you can see from the map above, most of the Illinois population is based in the North East of the state. Chicago, home to 2,695,598 people, remains the largest city in Illinois. It dwarfs the state's other cities â the next largest is Aurora, with 197,899 people.
The busiest neighborhood for Chicago gun violence is Austin, where so far 80 people have been gunned down. The neighborhood, which is out on the West Side about four miles from where the 44 th president used to live, counts a current population of just 100,000, which means it has a gun-death rate of 82 per 100,000, a number that simply cannot be believed.
