While bacterial dysbiosis in SLE is well characterized, the role of the gut mycobiome and its cross-kingdom interactions remains largely unexplored.  \nMethods Using fecal metagenomic sequencing from 117 SLE patients and 115 healthy controls (HCs), we established a non-redundant fungal genome catalog and revealed significant alterations in fungal composition, function, and cross-kingdom ecology.  \nResults Fungal diversity was increased in SLE, with enrichment of potentially pathogenic taxa such as Candida, Malassezia, and Trichophyton, and depletion of commensal genera such as Pichia. Functional analysis showed expanded biosynthetic and redox capacities in SLE-associated fungi, including enrichment of RiPP-and terpenerelated biosynthetic gene clusters and oxidative stress–related Pfam domains. Several predicted metabolites—such as kynurenine, phenylacetic acid, secondary bile acids, and acylcarnitines—were linked to immune activation and inflammation, suggesting that fungal metabolism may contribute to immune dysregulation. Network analysis revealed sparser and less centralized fungal–bacterial interactions in SLE, indicating disrupted ecological stability and the emergence of fungal taxa as key structural drivers. Integrating fungal and bacterial profiles markedly improved diagnostic performance (AUC = 0 . 934), underscoring the complementary predictive value of the gut mycobiome. In contrast, post-treatment samples showed reduced fungal richness but no major compositional shifts.  \n†Zheng Wang, Yida Xing, Mingxi Xu, Changming Chen and Qing Zhu have contributed equally to this work.  \n*Correspondence:  \nGuorui Xing [2657518@qq.com](2657518@qq.com)[ ](2657518@qq.com)Xueming Yao [yxming19@foxmail.com](yxming19@foxmail.com)[ ](yxming19@foxmail.com)Xiaodan Kong [xiaodankong2008@sina.com](xiaodankong2008@sina.com)  \nFull list of author information is available at the end of the article  \n© The Author(s) 2025.
