PURPOSE: The Philippines ranks 9th among 22 high tuberculosis burden countries. In this high TB burden setting, is lymphocytic predominant exudative pleural effusion be secondary to tuberculosis ? This study aims to determine the demographic data and etiologies of lymphocytic predominant pleural effusion among patients admitted at the Philippine General Hospital (PGH).
METHODS: A retrospective, descriptive study was carried out at the Philippine General Hospital from March 2007 to February 2008. Medical Records of patients admitted with pleural effusion and were referred to the Section of Pulmonary Medicine were reviewed. Patients with lymphocytic exudative effusion were included in the study.
RESULTS: A total of 40 patients with lymphocytic predominant exudative effusion was included in the study with mean age (± SD) of 55.8 (±16.8) years, 21 (53 %) were males and 19 (48 %) were females. Majority of patients was more than 50 years old (n=24; 60%). The effusion was located on the right in (n= 21; 53%)of patients, on the left side in (n= 18; 45 % of patients, and bilateral in n= 1; 2% of patients. Malignancy was the most frequent cause of pleural effusion (n=28; 70%), while tuberculous pleurisy was the cause of pleural effusion in (n= 12; 30%) of our patients.
CONCLUSION: Our results demonstrate that malignancy is the most frequent cause of lymphocytic pleural exudate in our setting, an area with high incidence of tuberculosis.
CLINICAL IMPLICATIONS: In Lymphocytic predominant exudative pleural effusion, it is important to rule out first the possibility of malignancy before concluding that it is secondary to tuberculosis,though we belong to a high TB burden country.
