Cases of clozapine-induced myocarditis were defined as having elevated C-reactive protein (CRP) or detectable troponin and at least 1 sign or symptom of myocarditis, in the absence of alternative plausible aetiologies.
Hs-CRP, LAC and Mb are highly expressed in the serum of patients with myocarditis, and their combined detection has guiding significance for the prevention and treatment of myocarditis.
This was accompanied by a reduction in myocardial inflammation, as assessed by T2-weighted imaging (p = 0.005), native T1 mapping (p = 0.009) and ECV quantification (p = 0.001), as well as in serum inflammatory markers like CRP (p < 0.001) and ESR (p < 0.001), and clinical measures of disease activity (DAS28-CRP, p = 0.001; BASDAI, p < 0.001).
We present the case of a 31-year-old caucasian male with refractory schizophrenia who developed benign fever, increase of C-reactive protein and high troponin levels, without presenting any other signs to myocarditis, on the 13th day under clozapine treatment, which declined progressively upon discontinuation of the drug.
