The etiology of pleural effusions in an area with high incidence of tuberculosis.
To investigate the etiology of pleural effusions in our region, we undertook a prospective study of patients with this condition in our centers.
During a 5-year period, we studied 642 pleural effusion patients aged 57.1±21.1 years, of whom 401 were men aged 56.5±21 years and 241 were women aged 57.8±21.4 years ; the male/female ratio was 1.6 : 1. The most frequent cause of pleural effusion was tuberculosis (25%), followed by neoplasia (22.9%) and congestive heart failure (17.9%). The etiology of 48 cases (7.5%) remained uncertain.
In the neoplastic effusion group, the most frequent locations of the primary tumor were lung (32.6%), breast (11.5%), lymphoma (10.8%), and ovary (7.5%) ; in 21 cases (14.3% of the neoplastic group), it was not possible to identify the primary tumor.
The 111 patients aged younger than 40 years with tuberculous effusions made up 69.4% of tuberculous effusion cases and the same percentage of patients younger than 40 years ; the proportion of effusions that were tuberculous peaked in the 11-to 30-year-old age group and declined steadily thereafter.
Of the patients with neoplastic effusions, 83% were older than 50 years ; the proportion of effusions that were neoplastic rose steadily from zero in the 0-to 30-year-old age group to a peak among 60-to 70-year-olds.
The age-wise distribution of effusions secondary to congestive heart failure was similar to that of neoplastic effusions.
Of the effusions secondary to congestive heart failu...
