Case Report: Successful treatment of severe fever with thrombocytopenia syndrome associated with hemophagocytic lymphohistiocytosis by preemptively using favipiravir and methylprednisolone.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Severe fever with thrombocytopenia syndrome (SFTS) is an emerging infectious disease caused by a novel Bunyavirus with a high mortality rate. Cytokine storm could be regarded as an important feature of SFTS patients. Severe or critical cases of SFTS are often complicated with the presence of hemophagocytic lymphohistiocytosis (HLH), resulted in rapid disease progression and extremely adverse prognosis. Currently, effective treatments for these severe cases remain unavailable. Herein, we reported a case of SFTS associated with HLH successfully treated by favipiravir and methylprednisolone. Case presentation: A 73-year-old male farmer was admitted to our hospital with a fever, fatigue, and bicytopenia for 1 week on June 20, 2024. The patient had a history of farm work. The diagnosis of SFTS was confirmed by detection of Bunyavirus RNA in the blood samples. Bone marrow examination revealed marked infiltration of macrophages with hemophagocytosis in the bone marrow leading to a diagnosis of HLH. Notably, the patient was preemptively treated with favipiravir together with methylprednisolone and supportive therapy before the diagnosis of SFTS associated with HLH. Excitingly, the patient was recovered after 10 days treatment. Conclusion: Early recognition of SFTS complicated with HLH is particularly important, and the preemptive application of favipiravir may improve the prognosis of these patients.
