Background:
In areas where Mycobacterium tuberculosis is endemic, tuberculosis is known to be the most common cause of pericarditis. Although there are many reports on tuberculous (TB) pericarditis in HIV-infected persons, no large-scale prospective study on the treatment outcomes of HIV-uninfected patients with TB pericarditis has been reported. This is the first study to identify the predictive factors for unfavorable outcomes of TB pericarditis in HIV-uninfected persons in an intermediate tuberculosis burden country.
Methods:
A systematic review of 87 cases of TB pericarditis diagnosed at a tertiary referral hospital in South Korea during an 11-year period was performed. Clinical characteristics, treatment outcomes, complications during treatment, duration of treatment, and medication history were reviewed. Predictive factors for unfavorable outcomes were identified.
Results:
Of the 87 patients, 44 (50.6%) had unfavorable outcomes, with mortality in 4 patients. In the multivariate analysis, patients with large amounts of pericardial effusion (P = .003), those with hypoalbuminemia (P = .011), and those without cardiovascular disease (P = .011) were found to have a higher risk of unfavorable outcomes.
Conclusion:
HIV-uninfected patients with TB pericarditis are at a higher risk for unfavorable outcomes when presenting with low serum albumin, with large pericardial effusions, and without cardiovascular disease.
