Viral Venture: A Case of Myocarditis and IgA Vasculitis from Adenovirus Infection

Abstract Body (Do not enter title and authors here):
Case Description
A 19-year-old man presented to the emergency department for 3 days of shortness of breath, progressive bilateral lower extremity rash, generalized fatigue, and diffuse joint following an earlier visit to urgent care for pharyngitis symptoms. Physical exam was notable for tachycardia, pain with active wrist and ankle range of motion, pharyngeal erythema, cervical adenopathy, and confluent erythematous palpable purpura and petechiae noted on bilateral lower extremities with scattered lesions on his thighs, arms, and back. Laboratory workup notable for markedly elevated high-sensitivity troponin to 3398 ng/L, and elevated CRP. Further workup was notable for normal urinalysis, negative streptococcus antigen, negative ANCA antibodies, ANA, Hepatitis B and C, and cryoglobulins. Imaging and cardiac workup were notable for normal left ventricular function and cardiac MRI notable for late gadolinium enhancement in the anteroapical mid-myocardial region suggestive of myocarditis. Skin biopsy ultimately revealed immunodeposition of IgA on superficial capillaries compatible with a diagnosis of IgA vasculitis. The patient was started on steroids for IgA vasculitis with rapid improvement in his symptoms and he was discharged home in good condition.
Discussion
Recognizing the severe complications of viral infection can lead to prompt treatment and prevention of progression to severe end organ damage. Our case highlights rarely reported cardiac involvement of IgA vasculitis secondary to adenovirus infection based on laboratory and imaging diagnosis with cardiac MRI. To date, only 16 cases of cardiac involvement in IgA vasculitis have been reported. This case adds to the limited body of published cases describing this presentation of IgA vasculitis and is also consistent with the results of prior cases suggesting that an immunosuppressive regimen including glucocorticoids may help to prevent disease progression and induce remission in cases with cardiac involvement without the need for endomyocardial biopsy.
