RESUMO
Background: Tuberculous pleural effusion (TPE) is the most common etiology of exudative pleural effusion in high tuberculosis burden countries like Bangladesh. The usefulness of pleural fluid cholesterol for the diagnosis of TPE is not evaluated yet. This study aimed to assess the usefulness of pleural fluid cholesterol for the diagnosis of TPE. Methods: This cross-sectional study was conducted at the department of respiratory medicine at Bangabandhu Sheikh Mujib medical university. A total of thirty-five TPE was included in this study. Pleural fluid aspiration followed by cytological (total count, differential count), and biochemical (protein, glucose, lactate dehydrogenase, adenosine deaminase, and cholesterol) investigations were done. At the same time, blood was sent for biochemical (protein, glucose, and lactate dehydrogenase) investigation. Pleural biopsy followed by a histopathological examination was done to confirm TPE. Ethical clearance was obtained from the institutional review board (IRB) prior to starting this study. Results: In our study, the mean age of the participants was 35.54±14.13 years, and male predominant (74.3%). The mean pleural fluid cholesterol was 99.87±23.82 mg/dl. With a cut of value 69.85, the sensitivity, specificity, and accuracy were 97.14%, 57.14%, and 77.14% respectively. Conclusions: Pleural fluid cholesterol has significant diagnostic usefulness for the diagnosis of tuberculous pleural effusion.
RESUMO
Background: The pattern of bacterial infection in acute exacerbation of bronchiectasis is varied with geographical area and lobar distribution of bronchiectasis. The exact pattern of bacterial infection in acute exacerbation of bronchiectasis according to lobar distribution is not known in our country. This study aimed to investigate the pattern of bacterial infection in acute exacerbation of bronchiectasis according to lobar distribution. Methods: A total of eighty-four patients diagnosed with acute exacerbation of bronchiectasis were included in this cross-sectional study in the department of respiratory medicine, Bangabandhu Sheikh Mujib Medical University. Sputum culture and real-time polymerase chain reaction were used to characterize the bacterial profile and high-resolution computed tomography scans for the location of the bronchiectasis. Before enrolment, informed written consent was obtained from the participants. Results: The mean (SD) age of this study population was 47.89 (±14.95) years, 29.8% were female and 60.7% were a non-smoker. Bronchiectasis was more common in the right middle lobe (63.1%), followed by the right lower lobe (44%), and the left lower lobe (42%). Bacteria were isolated in 66% of patients and Gram-negative bacteria were predominant (78.6%). Pseudomonas aeruginosa (25%) and Klebsiella pneumoniae (17.9%) were the most common bacteria. Conclusions: Pseudomonas aeruginosa was identified predominantly in the right upper lobe, right middle lobe, left upper lobe, and bilateral upper lobe and Klebsiella pneumoniae was in the right lower lobe, left lower lobe, and bilateral lower lobe.
