Tuberculosis is one of the most frequent causes of exudative pleural effusions in immunocompetent patients. Tuberculosis is the leading cause of morbidity and mortality from an infectious disease in developing countries. Pakistan is ranked fifth in the world in terms of tuberculosis high-burden countries. Various pleural fluid parameters have been used to identify the cause of pleural effusion. It has been discovered that tuberculous pleural effusions had a greater alkaline phosphatase (ALP) concentration than transudative effusions. This study used pleural fluid alkaline phosphatase levels to distinguish between tuberculous pleural effusion and malignant pleural effusion because there is little information from tuberculosis-high burden nations like Pakistan. Study Design: A descriptive cross-sectional study conducted at the Jinnah Postgraduate Medical Center in Karachi between October 2016 and October 2017. Material and Methods: The study comprised all patients who were admitted to the department of chest medicine at Jinnah post graduate medical centre (JPMC) of either gender between the ages of 18 and 70 who had exudative lymphocytic pleural effusions lasting two weeks or more included in the study. Non probability consecutive sampling was used to collect data. Patients who have tonsillitis, pharyngitis, pneumonia, asthma, Chronic obstructive pulmonary disease (COPD), or a history of hemoptysis, Bleeding disorders like, platelet function disorder, thrombocytopenia, Liver cirrhosis and Pregnant women were excluded. Parents’ informed consent was obtained after being informed of the study’s protocol, hazards, and advantages. Each patient had their level of pleural fluid alkaline phosphate (PALP) assessed. In order to evaluate the patient’s pleural effusion, a pre-made questionnaire was used. All the collected data were entered into the SPSS 20. An independent sample t-test was used to recognize alkaline phosphate levels association with pleural fluid secondary to tuberculosis or malignancy. Results: In this Descriptive Cross-Sectional Study, the total of 156 patients with age Mean ± SD of was 41.96 ± 17.05 years. The majority of patients 110 (70.5%) were male and 46 (29.5%) were female. Advanced age was associated with raised pleural fluid alkaline phosphatase. The difference of pleural fluid alkaline phosphate level between tuberculous v/s malignant group was found to be (38.03 ± 45.97) v/s (82.77 ± 61.80) respectively with P-value (P = 0.0001). Conclusion: Malignant pleural effusions had elevated PALP when compared to tuberculous pleural effusions in exudative lymphocytic pleural effusions;better differences are seen in older ages and shorter disease durations.展开更多

We read with great interest the article by Gao and his colleagues proposing a new schema and hypothesis regarding pleural fluid turnover. In the proposed hypothesis, the visceral pleura possesses a more active role in humans than what was believed. The authors support the notion that in humans the pulmonary lymphatic vessels originate directly from the mesothelium of the visceral pleura and that it has an effect on both infiltration and reabsorption of pleural fluid in human beings.展开更多
