Recurrent pericarditis is defined when pericarditic chest pain reappears after a symptom-free period of at least 4 to 6 weeks and after completion of full-dose anti-inflammatory therapy. Idiopathic ...pericarditis is the commonest etiology. The diagnosis of idiopathic cases is essentially an exclusion diagnosis, supported by a typical clinical course. The diagnosis is based on the association of typical symptoms and signs: mainly pericarditic chest pain plus pericardial rubs or electrocardiographic alterations or pericardial effusion. The optimal regimen for recurrences includes combination of non-steroidal anti-inflammatory agents, colchicine, and corticosteroids. In the resistant forms, immunotherapy (azathioprine, intravenous immunoglobulins, and particularly anakinra) has shown to be effective. The long term outcome of idiopathic recurrent pericarditis is good, with no evolution towards constrictive form.
Abstract
Anti-interleukin (IL)-1 agents have been developed for the treatment of autoinflammatory and rheumatic conditions, where overproduction of IL-1 is an important pathophysiologic process. ...IL-1α and IL-1β are the most studied members of the IL-1 family of cytokines and have the strongest proinflammatory effects. A naturally occurring antagonist (IL-1Ra) mitigates their proinflammatory effects. Overproduction of both IL-1α (released by inflamed/damaged pericardial cells) and IL-1β (released by inflammatory cells) is now a well-recognized therapeutic target in patients with recurrent idiopathic pericarditis. Currently, there are three available anti-IL-1 agents: anakinra (recombinant human IL-1Ra), rilonacept (a soluble decoy receptor ‘trap’, binding both IL-1α and IL-1β), and canakinumab (human monoclonal anti-IL-1β antibody). For patients with corticosteroid-dependent and colchicine-resistant recurrent pericarditis with evidence of systemic inflammation, as evidenced by elevated C-reactive protein, the efficacy and safety of anakinra (2 mg/kg/day up to 100 mg/day subcutaneously usually for at least 6 months, then tapered) and rilonacept (320 mg subcutaneously for the first day followed by 160 mg subcutaneously weekly) have been clearly demonstrated in observational studies and randomized controlled clinical trials. Severe side effects are rare and discontinuation rates are very low (<4%). The most common reported side effect is injection site reactions (>50% of patients). In this article, we describe the historical and pathophysiological background and provide a comprehensive review of these agents, which appear to be the most significant advance in medical therapy of recurrent pericarditis in the last 5 years.

A 65-year old woman presented with recurrent hemoptysis. Four years earlier she had been treated (surgery plus radio-chemotherapy) for a cervical esophageal cancer with regional lymph nodes ...metastasis. Endoscopies showed areas of recent bleeding in the right pharynx. A 3D reconstruction from a CT angiogram of the neck vessels demonstrated a right internal carotid artery (ICA) pseudo-aneurysm. Selective endovascular occlusion of the aneurysm was planned. However, the patient had a recurrence of severe haemoptysis during coiling. A selective right ICA injection showed an extravascular jet of contrast medium filling the pharynx. Occlusion of the ICA and the pseudo-aneurysm (trapping) was performed as quickly as possible successfully staunching the bleed. Selective left ICA injection confirmed occlusion of the right ICA and satisfactory cross filling through the anterior communicating artery. The woman was discharged and the hemoptysis never recurred.
Abstract The pathogenesis of recurrent pericarditis is still poorly understood and may be related either to viral infections or autoimmune and autoinflammatory disorders. The immune system plays a ...major role in the pathogenesis of the disease, modulating individual responses to different noxa and explaining the variable reported recurrence rate (ranging from 20% to 50% of patients) following an attack of acute or recurrent pericarditis. Increasing interest is currently being devoted to autoinflammatory disorders, a group of conditions characterized by spontaneously relapsing and remitting bouts of systemic inflammation without apparent involvement of antigen-specific T cells or significant production of auto-antibodies. Ongoing basic and clinical research is needed to provide further evidence for the understanding of this common and troublesome disease, and to develop targeted and more efficacious therapies.
Studies suggest that anti-52 kDa Ro antibodies are more sensitive and specific than anti-60 kDa Ro antibodies for neonatal lupus. However, these studies mainly used immunoblot or ELISA using ...recombinant protein, which have poor sensitivity for anti-60 kDa Ro antibodies. In addition, the control patients were not disease matched. We reassessed the sensitivity and specificity of anti-52 kDa Ro, anti-60 kDa Ro, and anti-La, addressing these limitations.
To assess sensitivity, 125 mothers of children with neonatal lupus (NLM) were recruited. All maternal sera were assessed using a commercial line immunoassay that uses natural 60 kDa Ro protein (Inno-Lia ANA Update, Innogenetics NV, Gent, Belgium). By this method, 96% of the sera had antibodies to 60 kDa Ro, 86% to 52 kDa Ro, and 78% to 48 kDa La. Immunoblot of 65 NLM showed significantly fewer positive results for anti-60 kDa Ro (p < 0.001) and anti-52 kDa Ro (p < 0.05). Sensitivity of the 3 antibodies was assessed in the symptomatic mothers of children with congenital heart block (CHB) (78 women) and disease matched controls with unaffected children (65 women) using Inno-Lia ANA Update. The sensitivity of each antibody was compared by multiple logistic regression to adjust for maternal disease. There was no significant difference between the groups for 60 kDa Ro or for anti-52 kDa Ro antibody. However, there was a significant difference for the anti-La antibody (p = 0.001), with an odds ratio of 3.59. This translates to an increase in risk from a published 2% for CHB in an anti-Ro-positive mother to 3.1% if the woman is also anti-La antibody-positive, and to a decrease in risk to 0.9% if anti-La-negative.
Contrary to previous reports, 52 kDa Ro as detected by Inno-Lia ANA Update is not more specific for or frequent in CHB than 60 kDa Ro. However, the presence of anti-La antibodies significantly increases the risk for CHB.

Pericarditis is an inflammatory syndrome involving pericardium, which is a double-walled sac consisting of two leaves, a serous visceral layer in contact with the myocardium (pericardium) and a ...parietal fibrous one, delimiting a cavity (pericardial cavity) containing pericardial fluid. Pericarditis may occur isolated or as a manifestation of a systemic disorder. Diagnosis and correct management of pericarditis can be difficult and its natural history is often characterized by a lot of relapses. Treatment of acute pericarditis should target the underlying etiology. The diagnosis is based on characteristic clinical findings, electrocardiogram, and echocardiography. The goals of treatment are relief of pain, resolution of inflammation (and, if present, pericardial effusion), and prevention of recurrence. Despite a significant impairment of the quality of life, pericarditis usually has good long-term outcomes.
Background The efficacy and safety of colchicine for the primary prevention of the postpericardiotomy syndrome (PPS), postoperative effusions, and postoperative atrial fibrillation (POAF) remain ...uncertain. Although preliminary data from a single trial of colchicine given for 1 month postoperatively (COPPS trial) were promising, the results have not been confirmed in a large, multicenter trial. Moreover, in the COPPS trial, colchicine was given 3 days postoperatively. Methods The COPPS-2 study is a multicenter, double-blind, placebo-controlled randomized trial. Forty-eight to 72 hours before planned cardiac surgery, 360 patients, 180 in each treatment arm, will be randomized to receive placebo or colchicine without a loading dose (0.5 mg twice a day for 1 month in patients weighing ≥70 kg and 0.5 mg once for patients weighing <70 kg or intolerant to the highest dose). The primary efficacy end point is the incidence of PPS, postoperative effusions, and POAF at 3 months after surgery. Secondary end points are the incidence of cardiac tamponade or need for pericardiocentesis or thoracentesis, PPS recurrence, disease-related admissions, stroke, and overall mortality. Conclusions The COPPS-2 trial will evaluate the use of colchicine for the primary prevention of PPS, postoperative effusions, and POAF, potentially providing stronger evidence to support the use of preoperative colchicine without a loading dose to prevent several postoperative complications.
