The value of ascitic fluid adenosine deaminase activity in distinguishing tuberculosis from other causes of ascites was examined in a retrospective study of 41 patients with bacteriologically confirmed tuberculous peritonitis and 41 control patients, matched for age and sex, with ascites of other causes (12 alcoholic cirrhosis, 5 cryptogenic cirrhosis, 12 malignant disorders, 3 pancreatitis, and 9 miscellaneous causes). The mean ascites adenosine deaminase activity was 99.8 (SD 49.1) in tuberculous patients and 14.8 (8.4) U/l in control patients (p less than 0.0001). A cutoff of 32.3 U/l had a sensitivity of 95% and specificity of 98% in distinguishing between the two groups. In a subsequent prospective study of 64 patients with ascites, 11 were found to have tuberculosis. Of the others, 23 had cirrhosis (18 alcoholic, 5 cryptogenic), 17 malignant disorders, 3 pancreatitis, 5 cor pulmonale, 3 congestive cardiac failure, 1 systemic mastocytosis, and 1 renal failure and hypothyroidism. The mean ascites adenosine deaminase activity was 112.6 (45.0) U/l in the patients with tuberculous ascites and 16.3 (36.7) U/l (p less than 0.0001) in those with ascites of other causes. In this study, adenosine deaminase had a sensitivity of 100% and specificity of 96% in discriminating tuberculosis from other causes of ascites. These findings suggest that the ascitic fluid adenosine deaminase activity may be used to identify patients in whom the diagnosis of abdominal tuberculosis must be pursued.

The administration of anthocyanin dyes from Aronia melanocarpa in the rats before the intraperitoneal injections of PAF and ceruleine have a beneficial effect on the development of the acute experimental pancreatitis. It was revealed the reduction of pancreas swelling and decreasing of lipid peroxidation and adenosine deaminase activity. The examination was carried out on 149, weighing 200-250 g, female and male Wistar rats. They lived in the animal quarters with a stable temperature and humidity being fed with standard fodder (Murigan) and water ad libitum.

In a patient with an undiagnosed pleural effusion, the first question to answer is whether the fluid is an exudate or a transudate. This is usually determined by means of Light's criteria, which differentiate transudative effusions from exudative effusions by measuring the levels of total protein and lactate dehydrogenase in the pleural fluid (PF) and serum. In patients under diuretic treatment, Light's criteria misclassify transudates as exudates, but the serum to pleural fluid albumin gradient usually remains above 12 g/L. When tests are done only in PF, protein concentration >30 g/L performs at least as well as the other individual markers. To diagnose tuberculous pleuritis among exudates, PF adenosine deaminase and PF interferon-g exhibit high diagnostic accuracy. When malignancy is suspected the addition of tumour markers to the results of cytologic analysis increases the rate of detection. Other biochemical markers are useful in specific circumstances involving pleural effusion, such as amylase in effusions due to pancreatitis, or oesophageal rupture, and triglycerides in chylothorax. Several PF markers are associated with complicated parapneumonic effusion - e.g. low PF pH and glucose, and high PF LDH activity -- although PF pH appears to be the best biochemical aid in decisions regarding chest tube drainage. Recent reports suggest that neutrophil-derived enzymes (polymorphonuclear elastase and myeloperoxidase) can be useful as early indicators of the need of chest tube insertion; however these findings must be confirmed in large series. This review discusses the clinical usefulness of biochemical markers in the diagnosis and management of pleural effusions. The vast majority of prospective studies in this field have been conducted in adults and, although the mechanisms of pleural effusion production do not differ in children and adults, the prevalence of each etiologic cause does. Therefore it seems advisable to confirm or recalculate the predictive values of each marker in the paediatric population.

Ascites is the pathologic accumulation of fluid within the peritoneal cavity. Because many diseases can cause ascites, in particular cirrhosis, samples of ascitic fluid are commonly analyzed in order to develop a differential diagnosis. The concept of transudate versus exudate, as determined by total protein measurements, is outdated and the use of serum-ascites albumin gradient as an indicator of portal hypertension is more accurate. Lactate dehydrogenase (LDH), vascular endothelial growth factor (VEGF), and other tumor markers can be helpful in distinguishing between malignant and benign conditions. Glucose and adenosine deaminase levels may support a diagnosis of tuberculous disease, and amylase level may indicate a diagnosis of pancreatitis. Given the specificity and sensitivity of laboratory results, accurate diagnosis should be based on both laboratory data and clinical judgment.
