Successful Treatment of Type 1 Cryoglobulinemic Vasculitis With Cardiac Involvement

Cryoglobulinemic vasculitis is a rare and frequently fatal type of myocarditis. Cardiac manifestations in type 1 cryoglobulinemic vasculitis have never been reported to our knowledge. We report a rare case of type 1 cryoglobulinemic vasculitis with cardiac involvement in a patient who experienced progressive heart failure during the diagnosis. The diagnosis was made by the presence of cryoglobulins and endomyocardial biopsy results. After bortezomib-containing treatments, plasma cryoglobulin levels returned to normal, and the patient's clinical condition gradually improved.     

Coronary Artery Aneurysms Presenting as Acute Coronary Syndrome: An Unusual Case of IgG4-Related Disease Vascular Involvement

We report the case of a 65-year-old man referred to our department because of a complex coronary aneurysmal disease presenting as subacute ST-segment elevation myocardial infarction due to intraluminal thromboembolism. The patient’s past medical history (recurrent episodes of lymphadenopathies, parotid swelling, prostatitis, and dacryoadenitis) raised the suspicion of a unifying systemic disorder with coronary involvement. An extensive infectious and autoimmune screening was performed, leading to the final diagnosis of IgG4-related disease. Our case highlights the importance to include this rare and recently described disease in the diagnostic workup of acquired coronary aneurysms.
