Background: Scrub typhus, a disease caused by Orientia tsutsugamushi, triggers systemic vasculitis and is prevalent in Eastern and Southern Asia. This study aimed to uncover the relationship between scrub typhus and autoimmune responses, focusing on antinuclear antibodies (ANAs) and the implications of elevated ANA titers during infection.
Method: Data from a total of 139 patients diagnosed with scrub typhus and 30 healthy controls were retrospectively analyzed through serum samples to assess the levels of ANAs and related autoantibodies.

This case report presents a child with underlying G6PD deficiency who experienced an acute episode of extensive intravascular hemolysis induced by a scrub typhus infection. The key takeaway from this report is that scrub typhus infection can trigger extensive hemolysis in patients with even "mild" G6PD deficiency, and normal G6PD levels found during the acute phase of hemolysis do not rule out the possibility of underlying G6PD deficiency.
