ABSTRACT

Background: Prevalence of chylothorax (QT) is unknown at INER. Objectives: a) to determine one-year prevalence of chylothorax; b) to describe the characteristics of pleural effusion (PE); c) to determine the etiology of the chylothorax; and; d) to compare the frequency of chylothorax diagnosed by triglycerides (TG ) in PE versus chylothorax frequency by TG determination only in milky pleural effusion. Material and methods: We included patients diagnosed with PE at the hospital entry (2011-2012). We collected samples of PE which were sent to the Clinical Laboratory of the INER. For this study determined the TG mg/dL in PE. Statistical analysis was done according to the distribution of variables. Results: a) One-year prevalence of chylothorax (PE TG› 110 mg/dL) was 5.3%; b) characteristics of PE: 91.5% exudates, transudates 8.5%, mean cholesterol 71.5 (±50) and mean TG 58.5 (±150) mg/dL, c) chylothorax causes: infections and lung cancer, and d) evidence of TG in PE diagnosed 60% more cases of chylothorax versus TG analysis only in milky pleural effusion ([5.1 versus 0.9%], p = 0.0001). Conclusions: One-year prevalence was of chylothorax: 5.3%. The causes of chylothorax were: infections and lung cancer. TG test in DP is useful in diagnosing chylothorax.
