Weakly positive correlations were seen between pleural fluid ADA and pleural lactate dehydrogenase (LDH), r = 0.427, p < 0.001, and pleural absolute lymphocyte count, r = 0.314, p < 0.001. [3] -. Mycobacterium tuberculae causes tuberculosis. Ultimately, more research is needed prior to using these tests to make treatment decisions in the absence of AFB culture or pleural biopsy, and pragmatic trials would advance the field beyond the current excess of diagnostic accuracy studies. Regarding PE characteristics, the level of pleural ADA in the TPE group was significantly higher than in the MPE group (47.2 vs. 10.1 U/mL, P<0.001). Adenosine deaminase for diagnosis of tuberculous pleural effusion: A Multivariate linear regression analysis was performed and we found that the independent predictors of pleural fluid ADA were age, pleural fluid protein, LDH, and absolute lymphocyte count. Correlation between ADA and specified variables was quantified using Pearson correlation coefficient. Tuberculosis is a leading cause of death from infectious disease. Abrams LD. Diagnostic value of interferon-gamma in tuberculous pleurisy: a metaanalysis. This suggests that patient immune status as well as demographic factors may affect pleural fluid ADA levels.However, few studies have looked into factors which can affect pleural fluid ADA levels. Clinical diagnostic algorithm in defining tuberculous unilateral Thorax. Tuberculosis Respir Dis. 10.1111/j.1440-1843.2011.02100.x. Other authors have also shown that young patients with TPE have a much higher level of pleural fluid ADA. ada threshold categories were arbitrarily selected based on general expert opinions that (a) ada levels below 40 iu/l may rule out a diagnosis of tpe, (b) the most common diagnostic threshold is around 40 iu/l, and (c) higher ada levels (especially above 70 iu/l or so in a lymphocytic pleural effusion) virtually establish a diagnosis of tpe [ 3, Pleural effusion (PE) is common in patients who visiting the department of emergency, respiratory or thoracic diseases ( 1 ). 2007. Highly alkalotic pleural effusions can be seen in the context of some Proteus species infections. Almost all patients with TPE have a pleural fluid ADA level above 40 U/L, which is the most widely accepted cutoff value for the diagnosis of TPE ( 2 ). Two acid-fast bacilli are seen in the center of the field. Characteristics of pleural effusion with a high adenosine deaminase Peripheral blood white cell counts and lymphocytes count had negligible correlation with ADA with r = 0.177, p = 0.025 and r = 0.201, p = 0.011 respectively. Repeat pleural fluid bacterial, fungal and AFB cultures (two slants on Lowenstein-Jensen media, one in liquid media with Mycobacterium Growth Indicator) were obtained and again no organisms were seen on Grams stain or AFB smear. 2001;2:298300. L 1 excluded tuberculosis in lymphocytic pleural effusions in 99% (403 of 407) of cases. California Privacy Statement, 2007;131(4):113341. 3rd ed. One possible explanation is that the number of older patients aged >55years was relatively small in the TPE group resulting in a less representative population. Published 2019 Mar 26. https://doi.org/10.1371/journal.pone.0213728.

[1] Pleural effusion can be a manifestation of a wide range of diseases, both local and systemic.

Tuberculosis is the principal cause of exudative pleural effusion, and TB pleurisy is the extrapulmonary form most commonly observed . . Seibert AF, Haynes J, Middleton R, Bass JB. 2004;4(1):6. https://doi.org/10.1186/1471-2334-4-6 Review. Pleural fluid ADA decreases with age and therefore increases the number of false negative results for diagnosis of TPE when a fixed cut-off level is used in an older population compared to a younger population.

We present a case of a human immunodeficiency virus-negative 37-year-old man with 4 months of an intermittent, non-productive cough with associated weight loss (body mass index of 19).

Limitations of the study include its retrospective nature but selection bias in this study would have been limited as all patients in our institution investigated for pleural effusion would have pleural fluid ADA performed. Serum total protein was 7.5 g/L and serum lactate dehydrogenase 194 units/L. Pleural effusion tracheal deviation The diagnostic characteristic is displacement of the pleural line. Seven nontuberculous exudates (8.0%) reached the diagnostic cutoff. Weber SF, Saravu K, Heller T, Kadavigere R, Vishwanath S, Gehring S, Blard S, And Pocus Eti Study Group. It is highly important that a systematic approach is undertaken during the investigation of pleural effusions. For patients > 55 years old the AUC is 0.959. [23] Tuberculosis pleural effusions can now be diagnosed accurately by increased levels of pleural fluid adenosine deaminase, above 40 U per liter. 80 (50%) patients were diagnosed with TPE, 23 (14.4%) had malignant effusions, 40 (25%) had parapneumonic effusions, and 17 (10.6%) had effusions which were classified as Others. A 2 tailed p value of <0.05 was taken to be statistically significant. Our findings seem to confirm that ADA-activity is a very good parameter for diagnosis of tuberculous effusion. J Leukoc Biol. Update on tuberculous pleural effusion - Wiley Online Library Receiver operating characteristics (ROC) curves were described for both age groups. For patients >55years old the AUC is 0.959.

Pleural fluid biochemical analysis: the past, present and future 1995, 50: 600-603.

Previous studies have demonstrated correlation between pleural ADA level and CD4 lymphocyte counts [8], as well as lower mean ADA level in Japanese patients with TPE [9]. Tuberculous pleural effusion: twenty-year experience. Diagnostic evaluation of a pleural effusion in adults - UpToDate Pleural effusion, sometimes referred to as "water on the lungs," is the build-up of excess fluid between the layers of the pleura outside the lungs. Our study suggests that patient and pleural fluid characteristics need to be considered during interpretation of pleural fluid ADA as it decreases with age and increases with pleural fluid protein. In case of malignant pleural effusion our findings co- relate with most of the authors. A pleural fluid ADA of 72IU/L would have a sensitivity of 95.1%, specificity of 87.5%, positive predictive value (PPV) of 95.1% and negative predictive value (NPV) of 87.5% for the diagnosis of TPE. rea de Concentrao: Ateno Integrada Sade da Mulher e da Criana Diagnostic significance of adenosine deaminase in pleural effusate for Pleural biopsy has been the procedure traditionally used to diagnose a pleural effusion caused by M. tuberculosis but carries substantial morbidity. Adenosine deaminase (ADA) activity is typically elevated in patients with tuberculous pleural effusion (TPE), but low ADA has occasionally been reported in patients with TPE. We report a case of a patient with a negative pleural fluid ADA who was found to have culture-positive and biopsy-proven Mycobacterium tuberculosis. There was significant correlation between pleural fluid ADA and age, pleural fluid protein, LDH, and fluid absolute lymphocyte count. Light RW. AFB = acid-fast bacillus.
