There is a scarcity of data regarding OI in children with SLE in resource-limited areas. This study aimed to determine the incidence of OI in childhood SLE, describe their characteristics, and identify associated risk factors.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>This study is a retrospective and prospective study from January 2009 to November 2025 at King Chulalongkorn Memorial Hospital, Thailand.

Person-year incidence of OI was 3.4 per 100 person-year (95% CI: 2.3-4.9).

Pulse intravenous methylprednisolone (IVMP) use during the past 3 months and high disease activity, defined as SLEDAI-2K score \u2265 11, were associated with an increased risk of OI in the multivariate model (adjusted OR, aOR 16.12; 95% CI 3.42-75.85 and aOR 3.46; 95% CI 1.44-8.31, respectively). Other variables, including cumulative prednisolone dose, cumulative cyclophosphamide exposure, complement 3 (C3) and C4 level, absolute lymphocyte count, and serum albumin, were not significantly associated with OI development after adjustment for potential confounders.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Fungal and CMV infections were common OI in pediatric SLE.
