Prognosis of idiopathic recurrent pericarditis as determined from previously published reports.

After a systematic review of all publications on recurrent pericarditis from 1966 to 2006, we identified 8 major clinical series including a total of 230 patients with idiopathic recurrent pericarditis (mean age 46 years, men/women ratio: 0.9). After a mean follow-up of 61 months, the complication rate was 3.5% cardiac tamponade and 0% constrictive pericarditis and left ventricular dysfunction. The overall life prognosis is excellent in idiopathic recurrent pericarditis and complications are uncommon. In conclusion constrictive pericarditis was never reported despite numerous recurrences, and the risk is lower than in idiopathic acute pericarditis (approximately 1%). Thus, it is important to reassure patients on their prognosis, explaining the nature of the disease, and the likely course. Therapeutic choices should take into account of the overall good outcome of these patients, including less toxic agents.

[Post-pericardiotomy syndrome].

Postpericardiotomy syndrome (PPS) is a common complication of cardiac surgery. This syndrome is characterized by postoperative fever, pericarditis and laboratory findings that confirm inflammation. Over the past years, different studies were conducted in order to determine the etiology of PPS. Understanding the mechanisms that activate the inflammatory syndrome (possibly an autoimmune response) will contribute to the understanding of similar inflammatory processes and will guide towards an optimal method of treatment. This article reviews most of the studies on this topic that were published in the past 20 years.

Schistosomiasis among travelers: new aspects of an old disease.

Schistosomiasis is increasingly encountered among travelers returning from the tropics; signs and symptoms of travelers may differ from those of local populations. During 1993-2005, schistosomiasis was diagnosed in 137 Israeli travelers, most of whom were infected while in sub-Saharan Africa. Clinical findings compatible with acute schistosomiasis were recorded for 75 (66.4%) patients and included fever (71.3%), respiratory symptoms (42.9%), and cutaneous symptoms (45.2%). At time of physical examination, 42 patients (37.1%) still had symptoms of acute schistosomiasis, chronic schistosomiasis had developed in 23 (20.4%), and 48 (42.5%) were asymptomatic. Of patients who were initially asymptomatic, chronic schistosomiasis developed in 26%. Diagnosis was confirmed by serologic testing for 87.6% of patients, but schistosome ova were found in only 25.6%. We conclude that acute schistosomiasis is a major clinical problem among travelers, diagnostic and therapeutic options for acute schistosomiasis are limited, and asymptomatic travelers returning from schistosomiasis-endemic areas should be screened and treated.

Pretreatment with corticosteroids attenuates the efficacy of colchicine in preventing recurrent pericarditis: a multi-centre all-case analysis.

AIMS: Effective prevention of recurrent pericarditis remains an important yet elusive goal. Corticosteroid therapy often needs to be continued for a prolonged period and causes severe side effects. We performed a multi-centre all-case analysis to investigate the efficacy of colchicine in preventing subsequent relapses of pericarditis, and addressed the hypothesis that pretreatment with corticosteroids may attenuate the beneficial effect of colchicine. METHODS AND RESULTS: One hundred and forty published and unpublished cases of patients treated with colchicine after at least two relapses of pericarditis were aggregated from European centres. Of those, 119 were included in the study group. Only 18% of the patients had relapses under colchicine therapy, and 30% after its discontinuation. There were significantly more relapses among male patients after colchicine treatment (36 vs. 17%, P=0.046), and those with previous corticosteroid treatment (43 vs. 13%, P=0.02). Multivariate logistic regression analysis identified previous corticosteroid therapy (OR 6.68, 95% CI: 1.65-27.02) and male gender (OR 4.20, 95% CI: 1.16-15.21) as independent risk factors for recurrence following colchicine therapy. CONCLUSION: Treatment with colchicine is highly effective in preventing recurrent pericarditis, while pretreatment with corticosteroids exacerbates and extends the course of recurrent pericarditis.
