Clinical response of tuberculous pericarditis to medical treatment: a retrospective survey.

BACKGROUND

The prevalence of tuberculosis has declined with advanced antituberculous chemotherapy. However, the occurrence of subsequent constrictive pericarditis in tuberculosis has not reduced. Clinical progress of tuberculous pericarditis was investigated in patients receiving antituberculous chemotherapy.

METHODS

Thirteen patients with tuberculous pericarditis (11 men and 2 women aged 14 to 86 years [mean 60.0 +/- 17.0]), treated initially with antituberculous medications were analyzed. All patients underwent pericardiocentesis on admission following echocardiography.

RESULTS

Dyspnea was the most common clinical pictures. Bloody effusion fluids were noted in 10 patients. Moreover, the lymphocytic fluids were present in 78% of all patients. The neutrophilic fluids tended to have a bloody color, and there was progress to constrictive pericarditis even for those on anti-tuberculous chemotherapy. Five patients with subsequent constrictive pericarditis received pericardiectomy within 3.5 months of admission. Three of them received pericardiectomy later, despite pericardial window procedure.

CONCLUSIONS

Follow-up by echocardiogram is necessary within three months after commencing medical treatment because of the high incidence of progression constrictive pericarditis despite aggressive medical treatment. Pericardiectomy seems to be the only solution to the catastrophic outcome of constrictive pericarditis.
