A brief history of familial Mediterranean fever - FMF is most common periodic fever syndr. an inherited polyserositis mainly affects Arabs, Armenians, Jews, & Turks. Hx may date back to 1802 & Heberden. Osler described 11 cases in 1895. 1st clear report 1945 by Siegal 10 pts. https://t.co/m20uO3bOoj

Single center study of 2741 ANA tests: 65% ANA negative, 31% ANA+ w/ nuclear staining patterns, & 2.0% ANA+ w cytoplasmic staining. Cytoplasmic - most were reticular, dense fine speckled next. Reticular assoc w/ primary biliary cholangitis (w/ Abs against M2). Dense fine https://t.co/JI7iGvw8xp

45 southern African American SLE pts compared to multiethnic cSLE, AA pts had signif higher Dz activity & greater damage accrual. Their mean SLICC score was 8.4, SLEDAI 13, but was 7.4 @6 mos & 4,7 @1 yr. They traveled an avg distance 75 miles to see Rheum https://t.co/NMlT4uo8jn https://t.co/uG5ofMGE6O

Prevalence of ANCA Assoc Vasculitis (especially GPA) in Alaskan Natives (AN/AI) is high. GCA prevalence is lower than White populations, but higher than many others. AN/AI peoples w/ AAV & GCA may present at younger ages with more severe disease https://t.co/dhiu6sPGBk https://t.co/rNCo25HGcn
