However, no previous research focused on investigating the role of IFN\u2010I gene expression in the ophthalmologic involvement of systemic lupus erythematosus (SLE). We aimed to assess the association between the IFN\u2010I gene signature and ophthalmologic involvement in SLE.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>\n                      Cross\u2010sectional study includes patients \u226518 years old, fulfilling the 2019 EULAR or American College of Rheumatology criteria for SLE. Ophthalmologic evaluation, the Systemic Lupus Erythematosus Disease Activity Index\u20102K index, and blood sample collection were performed at the time of study assessment. Peripheral blood mononuclear cells were isolated, RNA was extracted, and complementary DNA was synthesized. Gene expression of IFI27, IFI44L, IFIT1, ISG15, RSAD2, and SIGLEC1 was assessed by real\u2010time polymerase chain reaction, using RPLP0 and EEF1A1 as reference genes for normalization. The median normalized relative quantity of the genes for each patient was used to calculate the fold change (FC) of the \u201cInterferon Score.\u201d Group comparisons were conducted using the Mann\u2013Whitney\n                      <jats:italic>U<\/jats:italic>\n                      test, and correlations between variables were assessed using Spearman's rank correlation coefficient.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      We included 32 patients with SLE. Ocular involvement occurred in 62.5%, either due to aqueous\u2010deficient dry eye (46.88%) or lupus retinopathy. A higher expression of the IFN\u2010I gene was found in patients with ocular involvement (FC = 2.52 \u00b1 1.96;\n                      <jats:italic>P<\/jats:italic>\n                      = 0.0027)
