This case and review will illustrate the importance of considering<jats:italic>P. acnes<\/jats:italic>as a cause of idiopathic pericardial effusion and effusive constrictive disease. The patient was a 61-year-old male with history of osteoarthritis of the knee. He received an intra-articular steroid injection in July 2013. Two months later, he presented with atrial fibrillation and heart failure. He was found to have pericardial and bilateral pleural effusions which grew<jats:italic>P. acnes<\/jats:italic>. This organism was initially considered to be contaminant; however, as<jats:italic>P. acnes<\/jats:italic>was isolated from both pleural and pericardial fluids, he was started on oral amoxicillin. He was noted to have recurrence of effusions within 2 weeks with evidence of constrictive physiology by echocardiography. Treatment was subsequently changed to intravenous Penicillin G with marked symptomatic improvement, resolution of pericardial\/pleural effusions, and no echocardiographic evidence of constrictive pericarditis at 10 weeks follow-up. Pursuit and treatment of<jats:italic>P. acnes<\/jats:italic>could lead to prevention of constrictive pericarditis. We believe that further studies are needed to assess prevalence of<jats:italic>P. acnes<\/jats:italic>and response to intravenous Penicillin G in patients presenting with effusive constrictive disease.<\/jats:p>","DOI":"10.1155\/2015\/193272","type":"journal-article","created":{"date-parts":[[2015,6,17]],"date-time":"2015-06-17T21:00:42Z","timestamp":1434574842000},"page":"1-3","source":"Crossref","is-referenced-by-count":9,"title":["<i>Propionibacterium acnes<\/i>: A Treatable Cause of Constrictive Pericarditis"],"prefix":"10.1155","volume":"2015","author":[{"given":"Daniel","family":"Cruz","sequence":"first","affiliation":[{"name":"Osler Medical Service, Johns Hopkins School of Medicine, Baltimore, MD 21287, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Haitham","family":"Ahmed","sequence":"additional","affiliation":[{"name":"Division of Cardiology, Department of Medicine, Johns Hopkins Hospital, Baltimore, MD 21287, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yousuf","family":"Gandapur","sequence":"additional","affiliation":[{"name":"Department of Medicine, Good Samaritan Hospital, Baltimore, MD 21239, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M.
