TNF and Miyoshi myopathy: Concerning the time <48 h, higher levels of IFN-γ were observed in patients with PM (median 521.7 pg/mL, range 311.2-1353 pg/mL; P < 0.01 ) compared to MM (median 33.45 pg/mL, range 7.4-92.6 pg/mL), while TNF-α was significantly higher in the CSF of patients with MM (median 2549 pg/mL, range 1047–6513 pg/mL; P < 0.05) compared to patients with PM (median 340.4 pg/mL, range 241.5-895.5 pg/mL) (Figure 2).
