Treatment and Prophylaxis of Post-pericardiotomy Syndrome in Cardiac Surgery Patients: a Systematic Review.

PURPOSE: Post-pericardiotomy syndrome (PPS) is a common complication of cardiac surgery. This systematic review aimed to investigate the efficacy of colchicine, indomethacin, and dexamethasone in the treatment and prophylaxis of PPS. METHODS: Literature research was carried out using PubMed. Studies investigating ≥ 10 patients with clinically PPS treated with colchicine, dexamethasone, and indomethacin and compared with placebo were included. Animal or in vitro experiments, studies on < 10 patients, case reports, congress reports, and review articles were excluded. Cochrane risk-of-bias tool for randomized trials (RoB2) was used for the quality assessment of studies. RESULTS: Seven studies were included. Among studies with postoperative colchicine treatment, two of them demonstrated a significant reduction of PPS. In the single pre-surgery colchicine administration study, a decrease of PPS cases was registered. Indomethacin pre-surgery administration was linked to a reduction of PPS. No significant result emerged with preoperative dexamethasone intake. CONCLUSION: Better outcomes have been registered when colchicine and indomethacin were administered as primary prophylactic agents in preventing PPS and PE. Further RCT studies are needed to confirm these results.

Do Colchicine and Prednisone Affect the Rate of Recurrence of Post-Pericardiotomy Syndrome.

BACKGROUND: Post-pericardiotomy syndrome (PPS) is a major cause of pericarditis, yet data on the risk of recurrence are limited, and the impact of steroids and colchicine in this context is unknown. OBJECTIVES: To examine the effect of prednisone and colchicine on the rate of recurrence of PPS. METHODS: Medical files of patients diagnosed with PPS were reviewed to extract demographic, echocardiographic, X-ray imaging, and follow-up data. RESULTS: The study comprised 132 patients (57% men), aged 27-86 years. Medical treatment included prednisone in 80 patients, non-steroidal anti-inflammatory agents in 41 patients, colchicine monotherapy in 2 patients, and no anti-inflammatory therapy in 9 patients. Fifty-nine patients were given colchicine for prevention of recurrence. The patients were followed for 5-110 months (median 64 months). Recurrent episodes occurred in 15 patients (11.4%), 10 patients had a single episode, 4 patients had two episodes, and one patient had three episodes. The rate of recurrence was lower in patients receiving colchicine compared to patients who did not (8.5% vs. 13.7%), and in patients not receiving vs. receiving prednisone (7.7% vs. 13.8%) but the differences were non-significant. Twenty-three patients died and there were no recurrence-related deaths. CONCLUSIONS: The rate of recurrence after PPS is low and multiple recurrences are rare. The survival of patients with recurrent PPS is excellent. Prednisone pre-treatment was associated with a numerically higher rate of recurrence and colchicine treatment with a numerically lower rate, but the differences were non-significant.

Meta-analysis for the value of colchicine for the therapy of pericarditis and of postpericardiotomy syndrome.

BACKGROUND: Colchicine has been used as anti-inflammatory agent in pericardial effusion (PE). We sought to perform a meta-analysis of randomized trials assessing the efficacy and safety of colchicine in patients with pericarditis or postpericardiotomy syndrome (PPS). METHODS: In the systematic literature search following the PRISMA statement, 10 prospective randomized controlled studies with 1981 patients with an average follow-up duration of 13.6 months were identified. RESULTS: Colchicine reduced the recurrence rate of pericarditis in patients with acute and recurrent pericarditis and reduced the incidence of PPS (RR: 0.57, 95% CI: 0.44-0.74). Additionally, the rate of rehospitalizations as well as the symptom duration after 72 h was significantly decreased in pericarditis (RR 0.33; 95% CI 0.18-0.60; and RR 0.43; 95% CI 0.34-0.54; respectively), but not in PPS. Treatment with colchicine was associated with significantly higher adverse event (AE) rates (RR 1.42; 95% CI 1.05-1.92), with gastrointestinal intolerance being the leading AE. The reported number needed to treat (NNT) for the prevention of recurrent pericarditis ranged between 3 and 5. The reported NNT for PPS prevention was 10, and the number needed to harm (NNH) was 12, respectively. Late colchicine administration > 7 days after heart surgery did not reduce postoperative PE. CONCLUSIONS: Our meta-analysis confirms that colchicine is efficacious and safe for prevention of recurrent pericarditis and PPS, while it reduces rehospitalizations and symptom duration in pericarditis. The clinical use of colchicine for the setting of PPS and postoperative PE after heart surgery should be investigated in further multicenter RCT.

Colchicine in Pericardial Disease: from the Underlying Biology and Clinical Benefits to the Drug-Drug Interactions in Cardiovascular Medicine.

PURPOSE OF REVIEW: This is an in-depth review on the mechanism of action, clinical utility, and drug-drug interactions of colchicine in the management of pericardial disease. RECENT FINDINGS: Recent evidence about therapeutic targets on pericarditis has demonstrated that NALP3 inflammasome blockade is the cornerstone in the clinical benefits of colchicine. Such benefits extend from acute and recurrent pericarditis to transient constriction and post-pericardiotomy syndrome. Despite the increased utilization of colchicine in cardiovascular medicine, safety concerns remains unsolved regarding the long-term use of colchicine in the cardiac patient. Moreover, recent evidence has demonstrated that numerous cardiovascular medications, ranging from antihypertensive medication to antiarrhythmics, are known to interact with the CYP3A4 and/or P-gp system increasing the toxicity potential of colchicine. The use of adjunctive colchicine in the management of inflammatory pericardial diseases is standard of care in current practice. It is advised that a careful medication reconciliation with emphasis on pharmacokinetic is completed before prescribing colchicine in order to avoid harmful interaction by finding an alternative regimen or adjusting colchicine dosing.

Postpericardiotomy syndrome.

Postpericardiotomy syndrome (PPS) is a common complication following cardiac surgery. In most cases it develops 2 to 3 weeks after the operation. An inflammatory reaction develops in the pericardium or pleural space with fever, chest pain and dyspnea as typical symptoms. The disease process is usually self-limiting. At present, the etiology is unknown, but an immunological mechanism is suspected as the cause of the disease. The incidence of PPS is essentially dependent on diagnostic criteria, patient group and type of operation. Treatment is carried out with anti-inflammatory analgesics, combined with colchicine in more severe cases.

Colchicine for children with pericarditis: systematic review of clinical studies.

OBJECTIVE: To review the evidence for the efficacy and safety of colchicine in children with pericarditis. DESIGN: Systematic review. SEARCH STRATEGY: The following databases were searched for studies about colchicine in children with pericarditis (June 2015): Cochrane Central, Medline, EMBASE and LILACS. ELIGIBILITY CRITERIA: All observational and experimental studies on humans with any length of follow-up and no limitations on language or publication status were included. The outcomes studied were recurrences of pericarditis and adverse events. DATA EXTRACTION: Two authors extracted data and assessed quality of included studies using the Cochrane risk of bias tool for non-randomised trials. RESULTS: Two case series and nine case reports reported the use of colchicine in a total of 86 children with pericarditis. Five articles including 74 paediatric patients were in favour of colchicine in preventing further pericarditis recurrences. Six studies including 12 patients showed that colchicine did not prevent recurrences of pericarditis. LIMITATIONS: No randomised controlled trials (RCTs) were found. CONCLUSIONS: Although colchicine is an established treatment for pericarditis in adults, it is not routinely used in children. There is not enough evidence to support or discourage the use of colchicine in children with pericarditis. Further research in the form of large double-blind RCTs is needed to establish the efficacy of colchicine in children with pericarditis.

Role of diclofenac in the prevention of postpericardiotomy syndrome after cardiac surgery.

OBJECTIVE: Postpericardiotomy syndrome (PPS), which is thought to be related to autoimmune phenomena, represents a common postoperative complication in cardiac surgery. Late pericardial effusions after cardiac surgery are usually related to PPS and can progress to cardiac tamponade. Preventive measures can reduce postoperative morbidity and mortality related to PPS. In a previous study, diclofenac was suggested to ameliorate autoimmune diseases. The aim of this study was to determine whether postoperative use of diclofenac is effective in preventing early PPS after cardiac surgery. METHODS: A total of 100 patients who were administered oral diclofenac for postoperative analgesia after cardiac surgery and until hospital discharge were included in this retrospective study. As well, 100 patients undergoing cardiac surgery who were not administered nonsteroidal anti-inflammatory drugs were included as the control group. The existence and severity of pericardial effusion were determined by echocardiography. The existence and severity of pleural effusion were determined by chest X-ray. RESULTS: PPS incidence was significantly lower in patients who received diclofenac (20% vs. 43%) (P<0.001). Patients given diclofenac had a significantly lower incidence of pericardial effusion (15% vs. 30%) (P=0.01). Although not statistically significant, pericardial and pleural effusion was more severe in the control group than in the diclofenac group. The mean duration of diclofenac treatment was 5.11±0.47 days in patients with PPS and 5.27±0.61 days in patients who did not have PPS (P=0.07). Logistic regression analysis demonstrated that diclofenac administration (odds ratio [OR] 0.34, 95% confidence interval [CI] 0.18-0.65, P=0.001) was independently associated with PPS occurrence. CONCLUSION: Postoperative administration of diclofenac may have a protective role against the development of PPS after cardiac surgery.

Treatment with aspirin, NSAID, corticosteroids, and colchicine in acute and recurrent pericarditis.

Empiric anti-inflammatory therapy for acute and recurrent pericarditis is warranted for viral and idiopathic cases that represent most cases of pericarditis in developed countries. For specific uncomplicated etiologies, such as systemic autoimmune diseases and postpericardiotomy syndromes, the same drugs are also indicated. Aspirin and non-steroidal anti-inflammatory drugs (NSAID) are mainstay of therapy with the possible adjunct of colchicine, especially for recurrences. Corticosteroids are a second choice for difficult cases requiring multi-drug therapies and specific medical conditions (i.e., specific cases with systemic autoimmune diseases, postpericardiotomy syndrome, and pregnancy). Medical therapy of pericarditis should be individualized as much as possible providing the attack dose every 8 h to ensure full daily control of symptoms and till remission and C-reactive protein normalization, and then tapering should be considered. The present paper will review current evidence for the treatment of acute and recurrent pericarditis with aspirin, NSAID, corticosteroids, and colchicine.

Postcardiotomy syndrome: recurrent cardiac tamponade and an exquisite steroid response.

A 26-year-old woman presented moribund with fever and pleuritic chest pain 3 times in 4 months following elective aortic root surgery. She was admitted 41 days after surgery with cardiac tamponade requiring surgical drainage twice within 1 week. Despite this, she was re-admitted for a second time 4 days after discharge with persistent pericardial effusion. High fevers and an incidental regurgitant murmur were extensively investigated for and treated as possible endocarditis or graft infection without conclusive results. The patient spent a total of 61 days in hospital during this period, receiving seven different antibiotic courses. Her third admission, with most severe clinical features, nearly led to further surgery and removal of her aortic graft but instead culminated in a multidisciplinary team decision to initiate steroid therapy for postcardiotomy syndrome. A short course of oral prednisolone saw her pericardial effusion and symptoms resolve completely.

The post-pericardiotomy syndrome.

PURPOSE OF REVIEW: The postpericardiotomy syndrome (PPS) is a relatively common complication following cardiac surgery, whose epidemiology is not well known because there are no standardized definitions. The aim of the present study is to review more recent updates on the diagnosis, therapy, prognosis, and especially prevention of the PPS. RECENT FINDINGS: Recent studies suggest that it is time to develop standardized criteria for the diagnosis of the PPS to allow early recognition and treatment. Limited knowledge is still available on the pathogenesis of the syndrome, but it is now clear that the presumptive immune-mediated origin is not able to explain all cases. Treatment is largely empirical and based on antiinflammatory drugs either nonsteroidal or corticosteroids with the possible adjunct of colchicine, that has been demonstrated as a promising well tolerated and efficacious means to prevent several postoperative complications, including the PPS, pericardial and pleural effusions, and atrial fibrillation. SUMMARY: Contemporary series of the PPS are scarce. About 20% of patients are affected by the syndrome after cardiac surgery with a significant increase in hospital stay, readmissions, and management costs. The overall short-term and middle-term prognosis is relatively good but constriction may develop in a long-term follow-up in a minority of patients. Therapeutic and preventive strategies, especially based on the use of colchicine, are worthy of further investigations to develop a more evidence-based approach to treatment and prevention.

Postcardiac injury syndrome.

A 58-year-old man had undergone 2-vessel off-pump coronary artery bypass surgery (OPCAB), 1 month before he was admitted into the hospital with cardiac tamponade due to pericarditis. Postcardiac injury syndrome (PCIS) was diagnosed. In spite of receiving anti-inflammatory treatment, the patient developed relapsing PCIS.

Recurrent pericardial effusion after cardiac surgery: the use of colchicine after recalcitrant conventional therapy.

Pericardial effusion represents a common postoperative complication in cardiac surgery. Nonetheless, it can be resistant to conventional therapy leading to prolonged in-hospital stay and worsening of clinical conditions. Recent literature shows that colchicine therapy should be useful in the treatment of recurrent post surgical pericardial effusion. Hereby we report the case of a patient with postsurgical recurrent effusion treated with colchicine, and a review of literature concerning the use of this old drug.

Colchicine as an effective treatment for postpericardiotomy syndrome following a lung lobectomy.

Postpericardiotomy syndrome (PPS) is a frequent complication of various cardiac procedures that involve entry into the pericardium, but rarely occurs after pulmonary surgery because the pericardium is usually preserved during this procedure. The standard treatment for PPS is the administration of non-steroidal anti-inflammatory drugs (NSAIDs). Recent studies have indicated however, that colchicine may be useful for the treatment and prevention of this syndrome. Here, we describe the successful use of colchicine to treat PPS in a lung cancer patient who developed this complication following a lung lobectomy. A 64-year-old woman with a stage IA lung tumor underwent a left upper lobectomy with a mediastinal lymph node dissection. Severe precordial pain occurred 10 days after surgery, and accumulations of pericardial and pleural fluid were revealed by chest X-ray, echocardiogram, and chest computed tomography. These symptoms were not alleviated by antibiotics, thoracic cavity drainage, or NSAIDs. However, the administration of colchicine (initial dose of 1.0 mg and maintenance dose of 0.5 mg daily for three months) in combination with NSAIDs resolved these symptoms immediately after the first dosage. In addition, the patient remains free of any recurrent pericarditis at six months after this episode.

The effect of short-term prophylactic acetylsalicylic acid on the incidence of postpericardiotomy syndrome after surgical closure of atrial septal defects.

Postpericardiotomy syndrome (PPS), a potential complication of open heart surgery, has a variable clinical course and severity. This study evaluated the effectiveness of acetylsalicylic acid (ASA) prophylaxis in preventing PPS after surgical closure of atrial septal defects (ASDs) in pediatric patients. A retrospective review was performed for 177 patients who underwent uncomplicated ASD closure from 1986 to 2006. The study group received prophylactic ASA 20 to 50 mg/kg/day for 1 to 6 weeks after surgery, whereas the control group did not. The primary outcome was a diagnosis of PPS based on the presence of two or more of the following symptoms or signs occurring at least 72 h postoperatively: fever (temperature >38 degrees C), pericardial or pleural rub, and worsening or recurring anterior pleuritic chest pain. Consequently, PPS developed in 5 (2.8%) of the 177 children: 2.8% (3/106) in the control group and 2.8% (2/71) in the study group (p = 1.00). The secondary outcomes were frequency of other postoperative complications. Postoperative pericardial effusions experienced by 26.7% of the patients were identified more frequently in the treatment group (p < 0.001). Postoperative prophylaxis ASA at a dose of 20 to 50 mg/kg/day for 1 to 6 weeks after surgical closure of ASD does not decrease the incidence of PPS in pediatric patients.

[Recurrent delayed pericarditis after pacemaker implantation: a post-pericardiotomy-like syndrome?]. / Une péricardite retardée récidivante après implantation de pacemaker: un équivalent de syndrome de Dressler?

INTRODUCTION: Pacemaker implantation is a usual technique in cardiology which may be followed by acute pleural effusion and delayed unusual pericarditis. CASE REPORT: We reported the case of a 67 year-old man hospitalized for faintness. Rhythmical auricular disease was diagnosed and pacemaker was implanted without immediate complication. Though pericarditis with tamponade at the day 21 will require emergency pericardiotomy surgery. A recurrent pericarditis at day 45 was treated with anti-inflammatory drugs without relapse at the end of the treatment. DISCUSSION: Repeated delayed pericarditis after pacemaker surgery may be compared to the Dressler syndrome which occurs after myocardial infarction.
