Methicillin-resistant Staphylococcus aureus aortitis in a cardiac transplant patient

Non-infectious aortitis in an immunosuppressed renal transplant recipient with IgA nephropathy

A 54-year-old woman presented with atypical chest pain, fever and malaise. She was immunosuppressed with three agents following a living-donor kidney transplant 1 year previously. Her native kidney failure was secondary to biopsy-demonstrated crescentic IgA nephropathy, with systemic involvement. A CT pulmonary angiogram revealed an inflammatory cuff of soft tissue around the descending thoracic aorta suggesting aortitis. Inflammatory markers were elevated. Given her immunosuppression, the patient was screened extensively for infective causes and was empirically commenced on intravenous meropenem. After 72 hours of no clinical or serological response to antibiotic therapy, negative microbiological investigations and worsening inflammation on serial imaging, she was commenced on high-dose methylprednisolone for presumed inflammatory aortitis. Symptoms and inflammatory markers rapidly normalisedand the patient was discharged home on oral prednisolone. A clinical diagnosis of IgA-related aortitis was made. Imaging 3 months later showed complete resolution of the aortitis.

Clinical pathologic conference: A 65-year-old male with left-sided chest pain. A case of an unexpected occupational hazard

The authors present a case of a 65-year-old male who presented four times to the emergency department (ED) with left-sided chest pain. On the first three visits, the patient was admitted with a different diagnosis related to his chest pain. On the final visit, an abnormality on an imaging study performed in the ED led to the ultimate diagnostic test revealing the cause of the patient's symptoms. The patient's clinical presentation and ultimate clinical course are summarized, and a discussion of the differential diagnoses of his condition is presented.
