The contribution of serum adenosine deaminase (ADA) activity to the diagnosis of typhoid fever was assessed in 246 children and in 46 adults, by Giusti's original technique. Children included otherwise healthy patients admitted for elective surgical conditions or under follow up for epilepsy which were considered to be a control group (n: 81), presumptive viral diseases (n: 31), miscellaneous febrile diseases except for typhoid fever (n: 41), different kinds of bacteremia (n: 6), diarrhea due to Salmonella typhimurium (n: 14), viral hepatitis (n: 24), and culture proven typhoid fever (n: 49). Adult's group included 39 healthy controls and 7 patients with culture proven typhoid fever. Among children mean ADA activity was as follows: control group 28 +/- 7.8, viral disease 35.3 +/- 13.1, miscellaneous febrile disease 36.1 +/- 15.6, bacteremia group: 30.3 +/- 10.3, salmonellosis group 51.6 +/- 9, hepatitis group 68.3 +/- 34.5, typhoid fever group 124.4 +/- 40.8 U/I 37 degrees C. Among adults, values were 18.4 +/- 7.5 for controls and 112.8 +/- 19.2 U/I 37 degrees C in typhoid fever patients. In both adults and children ADA activity was significantly higher in the typhoid fever group (p < 0.0001). Untreated typhoid fever patients had their higher ADA activity between 10th and 15th day of illness. When ADA cut point was set at 80 U/I, sensitivity of the test was 91.8% and specificity was 91.4% as a preliminary clue to the recognition of typhoid fever.

The value of seric activity of adenosine deaminase has been detected in four group of patients with liver disease: acute viral hepatitis in 32 cases, liver cirrhosis in 30 cases, liver neoplasia in 12 cases, and cholelithiasis in 20 cases, against 30 patients as a control group. In addition, we studied 3 patients with alcoholic hepatitis and 1 with biliary cirrhosis. The highest level was found in hepatic cirrhosis and viral hepatitis the value being statistically significant and superior to the levels of the control group in 100% of the cases. This level was higher than normal in patients with liver tumor. The level was normal or mildly elevated in patients with cholelithiasis. The level was normal in patients with alcoholic hepatitis and high in biliary cirrhosis but lower than that observed in alcoholic cirrhosis.

In order to investigate purin and primidin metabolism pathways in hepatitis, adenosine deaminase (ADA) and guanosine deaminase (GDA) activities in sera of patients with different types and manifestations of viral hepatitis disease (A, B, C, D, E, chronic, acute) were investigated and compared with the control group of healthy individuals. Hepatitis cases were classified with respect to their serological findings and clinics. When compared all the hepatitis cases with the controls, levels of aspartate aminotransferase, alanine aminotransferase, and alkaline phosphatase enzymes, as well as ADA and GDA, were significantly higher than the control group (p<0.01). Levels of ADA and GDA in hepatitis cases were determined as 26.07 11.98 IU/l and 2.37 1.91 IU/l, respectively. When compared their ADA and GDA levels amongst the classified hepatitis groups, there was no difference in ADA levels amongst cases (p>0.05). However, GDA levels in hepatitis A group were closed to the controls. Increase in serum ADA activities in hepatitis forms may be dependent on and reflect the increase in phagocytic activity of macrophages and maturation of T-lymphocytes, and may be valuable in monitoring in viral hepatitis cases.
