Abstract

Background— The beneficial effect of immunosuppressive treatment on myocarditis is still controversial, possibly because the immunologic and virological profile of potential candidates is largely unknown. Methods and Results— Out of 652 biopsied patients, 112 had a histological diagnosis of active lymphocytic myocarditis; 41 of these 112 patients were characterized by progressive heart failure despite conventional therapy and were treated with prednisone and azathioprine for 6 months. All were resubmitted to cardiac catheterization, angiography, and endomyocardial biopsy at 1 and 6 months and followed-up for 1 year. A total of 21 patients responded with prompt improvement in left ventricular ejection fraction from 25.7±4.1% to 47.1±4.4% and showed evidence of healed myocarditis at control biopsy. Conversely, 20 patients failed to respond and showed a histological evolution toward dilated cardiomyopathy: 12 remained stationary, 3 underwent cardiac transplantation, and 5 died. We retrospectively performed a polymerase chain reaction on frozen endomyocardial tissue for the most common cardiotropic viruses and assessed circulating serum cardiac autoantibodies. Viral genomes were present in biopsy specimens of 17 nonresponders (85%), including enterovirus (n=5), Epstein-Barr virus (n=5) adenovirus (n=4), both adenovirus and enterovirus (n=1), influenza A virus (n=1), parvovirus-B19 (n=1), and in 3 responders, who were all positive for hepatitis C virus. Cardiac autoantibodies were present in 19 responders (90%) and in none of the nonresponders. Conclusions— In patients with active lymphocytic myocarditis, those with circulating cardiac autoantibodies and no viral genome in the myocardium are the most likely to benefit from immunosuppression. The beneficial effect of immunosuppression in hepatitis C virus myocarditis suggests a relevant immunomediated component of damage.

  • Virus-negative lymphocytic myocarditis may have alternative pathogenesis such as autoimmunity, hypersensitivity, or medication usage.

    The Discussion (page not specified in our copy) suggests that some lymphocytic myocarditis may be elicited by autoimmune disease, and its conclusion links the absence of viral genome with cardiac autoantibodies. It does not identify hypersensitivity or medication use as alternative causes. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • In some cases of lymphocytic myocarditis, viruses test negative while heart-specific autoantibodies are present.

    “Notably, in some cases of lymphocytic myocarditis, these viruses tested negative, while autoantibodies specific to the heart were present”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
