Pericarditis arises as a result of a wide spectrum of pathologies of both infectious and non-infectious aetiology, which lead to various degrees of fibrogenesis. Current understanding of the sequence of molecular events leading to pathological manifestations of constrictive pericarditis is poor. The identification of key mechanisms and pathways common to most fibrotic events in the pericardium can aid in the design and development of novel interventions for the prevention and management of constriction. We have identified through this review various cellular events and signalling cascades which are likely to contribute to the pathological fibrotic phenotype. An initial classical pattern of inflammation arises as a result of insult to the pericardium and can exacerbate into an exaggerated or prolonged inflammatory state. Whilst the implication of major drivers of inflammation and fibrosis such as tumour necrosis factor and transforming growth factor β were foreseeable, the identification of pericardial deregulation of other mediators(basic fibroblast growth factor, galectin-3 and the tetrapeptide Ac-SDKP) provides important avenues for further research.展开更多

Pulmonary localization is the most frequent and extra-pulmonary involvement, in particular serous, is possible. In this study, we analyze our results of surgical pericardial drainage in tuberculous pericarditis. <strong>Methodology</strong>: We carried out a retrospective study at the CHU Point G over a period of five years from January 2012 to December 2017. The histological examination carried out on all the surgical specimens made it possible to retain the diagnosis of tuberculous pericarditis. <strong>Results</strong>: We identified and operated on 49 cases of tuberculous pericarditis, i.e. 70% of the pericardial drainage performed during the same period. The average age was 31.5 years (28 men and 21 women). The most common clinical signs were dyspnea (61.2%), chest pain (26.6%) and fever (12.2%). Pericardial drainage with pericardial biopsy was performed by xiphoid route in all of our patients. The mortality and morbidity rates were 4.1% and 8.2%, respectively. <strong>Conclusion</strong>: Pericardial tuberculosis attacks are frequent in Mali. The etiological diagnosis is based on the histology of the pericardial biopsy which can only be obtained surgically.展开更多
