International collaborative systematic review of controlled clinical trials on pharmacologic treatments for acute pericarditis and its recurrences.

AbstractBACKGROUND:
Acute pericarditis is common, yet uncertainty persists on its treatment. We thus aimed to conduct a comprehensive systematic review on pharmacologic treatments for acute or recurrent pericarditis.
METHODS:
Controlled clinical studies were searched in several databases and were included provided they focused on pharmacologic agents for acute pericarditis or its recurrences. Random-effect odds ratios (ORs) were computed for long-term treatment failure, pericarditis recurrence, rehospitalization, and adverse drug effects.
RESULTS:
From 2,078 citations, 7 studies were finally included (451 patients); but only 3 were randomized trials. Treatment comparisons were as follows: colchicine versus standard therapy (3 studies, 265 patients), steroids versus standard therapy (2 studies, 31 patients), low-dose versus high-dose steroids (1 study, 100 patients), and statins versus standard therapy (1 study, 55 patients). Colchicine was associated with a reduced risk of treatment failure (OR = 0.23 [0.11-0.49]) and recurrent pericarditis (OR = 0.39 [0.20-0.77]), but with a trend toward more adverse effects (OR = 5.27 [0.86-32.16]). Overall, steroids were associated with a trend toward increased risk of recurrent pericarditis (OR = 7.50 [0.62-90.65]). Conversely, low-dose steroids proved superior to high-dose steroids for treatment failure or recurrent pericarditis (OR = 0.29 [0.13-0.66]), rehospitalizations (OR = 0.19 [0.06-0.63]), and adverse effects (OR = 0.07 [0.01-0.54]). Data on statins were inconclusive.
CONCLUSIONS:
Clinical evidence informing decision-making for the management of acute pericarditis and its recurrences is still limited to few, small, and/or low-quality clinical studies. Notwithstanding such major caveats, available studies routinely using nonsteroidal anti-inflammatory agents in both experimental and control groups suggest a beneficial risk-benefit profile for colchicine and a detrimental one for steroids, especially when used at high dosages.
