Red flag symptoms for presence of systemic autoimmune disease were reported by 5.6% of patients during initial evaluation (sicca syndrome [<jats:italic>n<\/jats:italic>\u2009=\u20095], joint pain [<jats:italic>n<\/jats:italic>\u2009=\u20094], dermatitis [<jats:italic>n<\/jats:italic>\u2009=\u20094]). Complement levels (C3c and C4) were below the lower reference level in 26 of 134 (19.4%) and three of 134 (2.2%), respectively. Antinuclear antibodies (ANAs) were positive in 24 of 210 (11.4%), with 18 (8.6%), five (2.4%), and one (0.5%) having mildly, moderately, and strongly positive ANA titers. Extractable nuclear antibody subsets were positive in 10 of 211 (4.7%) patients. ASPs led to the diagnosis of mixed connective tissue disease (<jats:italic>n<\/jats:italic>\u2009=\u20091), psoriatic arthritis (<jats:italic>n<\/jats:italic>\u2009=\u20091), and Sj\u00f6gren syndrome (<jats:italic>n<\/jats:italic>\u2009=\u20092; positive predictive value [PPV] =\u20094.9%, negative predictive value [NPV] =\u200999.3%).
