However, its presence in patients with systemic lupus erythematosus is rarely reported.Methods: We reported two SLE patients infected by T. marneffei and reviewed other patients reported in the English literature. All cases were pooled for analysis.Results: Eleven patients with SLE infected with T. marneffei infection were identified, including the two presented here. Three were male and eight were female; all were HIV negative. All the patients, except two where data were missing, had received immunosuppressants before T. marneffei infection. The main clinical features included fever, cough, lymph node enlargement, gastrointestinal symptoms, and rash. Five patients were misdiagnosed as having SLE exacerbation. T. marneffei was detected via culture or histopathologic analysis, with the fungus most commonly found in the blood. Seven of the 11 patients were successfully treated by timely antifungal therapy with concomitant SLE control, while four patients who did not receive antifungal therapy died.Conclusion: T. marneffei infection should be excluded when SLE patients, especially if on long-term immunosuppressants, present with fever, cough, lymph node enlargement, gastrointestinal symptoms, and rash. Controlling the lupus and timely antifungal treatment can improve the outcomes of SLE patients with T. marneffei infection.Keywords: Talaromyces marneffei, systemic lupus erythematosus, immunosuppressant
