Colchicine for the Treatment of Acute and Recurrent Pericarditis.

OBJECTIVE

To evaluate the literature with colchicine for the acute treatment of pericarditis and prevention of recurrent pericarditis.

DATA SOURCES

Searches of MEDLINE (1966-March 2014) and Cochrane Database (1993-March 2014) were conducted using the search terms pericarditis and colchicine. Limits were set for articles written in English with human subjects. Additional data were identified through bibliographic reviews.

STUDY SELECTION AND DATA EXTRACTION

Case series and clinical trials identified from the data sources were evaluated.

DATA SYNTHESIS

A total of 16 case series and 5 prospective controlled trials were identified in the search. Early observational studies examined the use of colchicine, as an adjunct to aspirin or nonsteroidal anti-inflammatory drugs (NSAIDs), in patients with multiple cases of recurrent pericarditis. These studies showed decreased rates of recurrence after the initiation of colchicine therapy and formed the basis of the only available guidelines for the treatment of pericarditis. Since then, 5 randomized controlled trials have been published; 3 trials studied colchicine therapy for 6 months in patients with recurrent pericarditis, and the other 2 studied colchicine therapy for 3 months in patients with acute pericarditis. All 5 trials showed decreased rates of recurrence and symptom persistence, with similar rates of adverse events between study groups.

CONCLUSIONS

Clinical controlled trials have shown that colchicine, as an adjunct to aspirin or NSAIDs, is effective in the prevention of recurrent pericarditis and in the management of acute symptoms. Colchicine was generally well tolerated with a low incidence of adverse events.
