RESUMO
BACKGROUND: Corticosteroid use is widespread in recurrent pericarditis, even if rarely indicated, and high doses (eg, prednisone 1.0 to 1.5 mg . kg(-1) . d(-1)) are generally recommended, although only weak evidence supports their use with possible severe side effects. The aim of this work was to compare side effects, recurrences and other complications, and hospitalizations of a low- versus high-dose regimen of prednisone for recurrent pericarditis. METHODS AND RESULTS: A retrospective review of all cases of recurrent pericarditis treated with corticosteroids according to different regimens from January 1996 to June 2004 was performed in 2 Italian referral centers. One hundred patients with recurrent pericarditis (mean age, 50.1+/-15.8 years; 57 females) were included in the study; 49 patients (mean age, 47.5+/-16.0; 25 females) were treated with low doses of prednisone (0.2 to 0.5 mg . kg(-1) . d(-1)), and 51 patients (mean age, 52.6+/-15.3; 32 females) were treated with prednisone 1.0 mg . kg(-1) . d(-1). Baseline demographic and clinical characteristics were well balanced across the groups. Each initial dose was maintained for 4 weeks and then slowly tapered. After adjustment for potential confounders (age, female gender, nonidiopathic origin), only high doses of prednisone were associated with severe side effects, recurrences, and hospitalizations (hazard ratio, 3.61; 95% confidence interval, 1.96 to 6.63; P<0.001). CONCLUSIONS: Use of higher doses of prednisone (1.0 mg . kg(-1) . d(-1)) for recurrent pericarditis is associated with more side effects, recurrences, and hospitalizations. Lower doses of prednisone should be considered when corticosteroids are needed to treat pericarditis.

RATIONALE: Colchicine seems to be well tolerated and effective in the treatment and prevention of pericarditis. A preliminary clinical trial has shown that colchicine may be considered not only for the treatment of postpericardiotomy syndrome (PPS), but also for its primary prevention. STUDY DESIGN: The COPPS study is a multicentre, double-blind, randomised trial. On the third postoperative day, 360 patients, 180 in each treatment arm, will be randomised to receive placebo or colchicine (1.0 mg twice daily for the first day followed by a maintenance dose of 0.5 mg twice daily for 1 month in patients > or =70 kg, and halved doses for patients <70 kg or intolerant to the highest dose). The primary efficacy endpoint is the incidence of PPS at 12 months. Secondary endpoints are disease-related hospitalisation, cardiac tamponade, constrictive pericarditis, and relapses at 18 months. Additional analysis will include the time to PPS. IMPLICATIONS: The COPPS trial will evaluate the use of colchicine for the primary prevention of PPS. This study will also provide important information on the frequency, clinical presentation, and prognosis of this syndrome in clinical practice.

BACKGROUND: The clinical search for indicators of poor prognosis of acute pericarditis may be useful for clinical triage of patients at high risk of specific causal conditions or complications. The aim of the present article is to assess the relationship between clinical features at presentation and specific causes or complications. METHODS AND RESULTS: A total of 453 patients aged 17 to 90 years (mean age 52+/-18 years, 245 men) with acute pericarditis (post-myocardial infarction pericarditis was excluded) were prospectively evaluated from January 1996 to August 2004. A specific cause was found in 76 of 453 patients (16.8%): autoimmune in 33 patients (7.3%), neoplastic in 23 patients (5.1%), tuberculous in 17 patients (3.8%), and purulent in 3 patients (0.7%). In multivariable analysis, women (hazard ratio [HR] 1.67, 95% confidence interval [CI] 1.03 to 2.70; P=0.036) and patients with fever >38 degrees C (HR 3.56, 95% CI 1.82 to 6.95; P<0.001), subacute course (HR 3.97, 95% CI 1.66 to 9.50; P=0.002), large effusion or tamponade (HR 2.15, 95% CI 1.09 to 4.23; P=0.026), and failure of aspirin or of nonsteroidal anti-inflammatory drugs (HR 2.50, 95% CI 1.28 to 4.91; P=0.008) were at increased risk of specific causal conditions. After a mean follow-up of 31 months, complications were detected in 95 patients (21.0%): recurrences in 83 patients (18.3%), tamponade in 14 patients (3.1%), and constriction in 7 patients (1.5%). In multivariable analysis, women (HR 1.65, 95% CI 1.08 to 2.52; P=0.020) and patients with large effusion or tamponade (HR 2.51, 95% CI 1.37 to 4.61; P=0.003) and failure of aspirin or of nonsteroidal anti-inflammatory drugs (HR 5.50, 95% CI 3.56 to 8.51; P<0.001) were at increased risk of complications. CONCLUSIONS: Specific clinical features (fever >38 degrees C, subacute course, large effusion or tamponade, and aspirin or NSAID failure) may be useful to identify higher risk of specific causal conditions and complications.

BACKGROUND: Colchicine is effective and safe for the treatment and prevention of recurrent pericarditis and might ultimately serve as the initial mode of treatment, especially in idiopathic cases. The aim of this work was to verify the safety and efficacy of colchicine as an adjunct to conventional therapy for the treatment of the first episode of acute pericarditis. METHODS AND RESULTS: A prospective, randomized, open-label design was used. A total of 120 patients (mean age 56.9+/-18.8 years, 54 males) with a first episode of acute pericarditis (idiopathic, viral, postpericardiotomy syndromes, and connective tissue diseases) were randomly assigned to conventional treatment with aspirin (group I) or conventional treatment plus colchicine 1.0 to 2.0 mg for the first day and then 0.5 to 1.0 mg/d for 3 months (group II). Corticosteroid therapy was restricted to patients with aspirin contraindications or intolerance. The primary end point was recurrence rate. During the 2873 patient-month follow-up, colchicine significantly reduced the recurrence rate (recurrence rates at 18 months were, respectively, 10.7% versus 32.3%; P=0.004; number needed to treat=5) and symptom persistence at 72 hours (respectively, 11.7% versus 36.7%; P=0.003). After multivariate analysis, corticosteroid use (OR 4.30, 95% CI 1.21 to 15.25; P=0.024) was an independent risk factor for recurrences. Colchicine was discontinued in 5 cases (8.3%) because of diarrhea. No serious adverse effects were observed. CONCLUSIONS: Colchicine plus conventional therapy led to a clinically important and statistically significant benefit over conventional treatment, decreasing the recurrence rate in patients with a first episode of acute pericarditis. Corticosteroid therapy given in the index attack can favor the occurrence of recurrences.

Fifty-five of 294 consecutive patients with acute pericarditis had first attacks of recurrent pericarditis and were evaluated and treated according to a management protocol. Corticosteroids were restricted to aspirin contraindication or failure. Colchicine was added in cases of aspirin and prednisone failure and was the treatment of choice for the second and subsequent recurrences. After logistic regression multivariate analysis, only the previous use of corticosteroids (odds ratio 10.35, 95% confidence interval 4.46 to 23.99, p <0.001) was associated with an increased risk for recurrence. After a mean follow-up of 72 months (range 48 to 108), a similar rate of complications was found in patients with or without recurrences.

Neoplastic etiology was found in 33 of 450 patients with acute pericardial disease (7.3%). Acute pericardial disease was the first manifestation of previously unknown malignancies in 18 of 450 patients (4.0%), and lung cancer was the most common malignancy (72.2%, p = 0.02). The following clinical characteristics were associated with a greater probability of a neoplastic etiology: a history of malignancy (odds ratio [OR] 19.8), cardiac tamponade at presentation (OR 7.0), a lack of response to nonsteroidal anti-inflammatory drugs, and recurrent or incessant pericarditis (OR 10.0). A similar prognosis was found in patients with or without a history of known cancer.

Recurrent pain without clinical evidence of acute pericarditis was recorded in 27 of 275 patients (9.8%; mean age 55.6 +/- 16.0 years, female/male ratio 20/7) with previous viral or idiopathic acute pericarditis. Female gender (odds ratio [OR] 4.3, 95% confidence interval [CI] 1.8 to 10.6), previous use of corticosteroids (OR 5.2, 95% CI 2.2 to 12.3), and previous recurrent pericarditis (OR 3.7, 95% CI 1.3 to 10.2) were identified as risk factors for this syndrome. After a mean follow-up of 40 months, a higher recurrence rate was recorded in these patients (33.3% vs 14.1%; p = 0.02) as well as a nonsignificant trend to a higher rate of constrictive pericarditis.

OBJECTIVES: We sought to investigate the safety and efficacy of a protocol for acute pericarditis triage and outpatient management of low-risk cases. BACKGROUND: Acute pericarditis has generally a brief and benign course after empiric treatment by non-steroidal anti-inflammatory drugs, and routine hospitalization of most patients may be unnecessary. METHODS: From January 1996 to December 2001, all consecutive cases of acute pericarditis were evaluated on a day-hospital basis. Patients without clinical poor prognostic predictors (fever >38 degrees C, subacute onset, immunodepression, trauma, oral anticoagulant therapy, myopericarditis, severe pericardial effusion, cardiac tamponade) were considered low-risk cases and assigned to outpatient treatment with high-dose oral aspirin. Patients with poor prognostic predictors or aspirin failure were hospitalized for etiology search and treatment. A clinical and echocardiographic follow-up was performed at 48 to 72 h, 7 to 10 days, 1 month, 6 months, and 1 year. RESULTS: Two hundred fifty-four out of 300 (84.7%) patients were selected as low-risk cases. Outpatient treatment was efficacious in 221 out of 254 (87%) cases. Thirty-three out of 254 patients were hospitalized because of aspirin failure. Patients treated on an out-of-hospital basis had no serious complications after a mean follow-up of 38 months (no cases of cardiac tamponade). A higher frequency of recurrences and constriction was recorded in aspirin-resistant cases than in aspirin responders (60.6% vs. 10.4% for recurrences and 9.1% vs. 0.5% for constriction, respectively; all p < 0.01). CONCLUSIONS: A protocol for acute pericarditis triage and outpatient therapy of low-risk cases is safe and efficacious and may reduce management costs.

OBJECTIVES: This study was designed to investigate the prognostic value of cardiac troponin I (cTnI) in viral or idiopathic pericarditis. BACKGROUND: Idiopathic acute pericarditis has been recently reported as a possible cause of nonischemic release of cTnI. The prognostic value of this observation remains unknown. METHODS: We enrolled 118 consecutive cases (age 49.2 +/- 18.4 years; 61 men) within 24 h of symptoms onset. A highly sensitive enzymoimmunofluorometric method was used to measure cTnI (acute myocardial infarction [AMI] threshold was 1.5 ng/ml). RESULTS: A cTnI rise was detectable in 38 patients (32.2%). The following characteristics were more frequently associated with a positive cTnI test: younger age (p < 0.001), male gender (p = 0.007), ST-segment elevation (p < 0.001), and pericardial effusion (p = 0.007) at presentation. An increase beyond AMI threshold was present in nine cases (7.6%), with an associated creatine kinase-MB elevation, a release pattern similar to AMI, and echocardiographic diffuse or localized abnormal left ventricular wall motion without detectable coronary artery disease. After a mean follow-up of 24 months a similar rate of complications was found in patients with a positive or a negative cTnI test (recurrent pericarditis: 18.4 vs. 18.8%; constrictive pericarditis: 0 vs. 1.3%, for all p = NS; no cases of cardiac tamponade or residual left ventricular dysfunction were detected). CONCLUSIONS: In viral or idiopathic acute pericarditis cTnI elevation is frequently observed and commonly associated with young age, male gender, ST-segment elevation, and pericardial effusion at presentation. cTnI increase is roughly related to the extent of myocardial inflammatory involvement and, unlike acute coronary syndromes, is not a negative prognostic marker.
