Abstract
AIMS Cytidine deaminase (CDA) activity in cancer patients' serum has been proposed as a predictive biomarker for efficacy and toxicity of nucleoside analogues. However, discrepant results about its predictive value have been reported due to the high interindividual variability in CDA activity. This study aimed at identifying determinants of this interindividual variability. METHODS From December 2014 to November 2015, 183 patients were prospectively included. Serum CDA activity, biological and clinical characteristics as well as five common single nucleotide polymorphisms (SNPs) in the CDA gene (c.-451C > T, c.-92A > G, c.-33_-31delC, c.79A > C, c.435 T > C) were analysed. Associations between clinical characteristics, pharmacogenetic variants and CDA activity were univariately tested. P < 0.1-candidate variables were analysed through a multivariate analysis. The association between CDA activity and toxicity was assessed for the 56 gemcitabine-treated patients. Intraindividual variability in CDA activity was explored in six pancreatic cancer patients treated with gemcitabine. RESULTS Median CDA activity was 3.97 U mg-1 (range 1.53-15.49 U mg-1 ). A univariate analysis showed that CDA activity was statistically associated with Eastern Cooperative Oncology Group performance status, mild or severe malnutrition, inflammatory syndrome, leucocyte count, neutrophil count, albumin, C-reactive protein and -c.-33_-31delC single nucleotide polymorphism. A multivariate analysis identified that only neutrophil count (P < 0.0001) and severe malnutrition (P = 0.0278) were independently associated with CDA activity. Low CDA activity (<2 U mg-1 ) was not statistically associated with severe gemcitabine-related toxicities (P = 0.16). A decrease in CDA activity was observed during the longitudinal follow-up of six pancreatic cancer patients treated with gemcitabine (P = 0.03). CONCLUSIONS These results suggest that neutrophil count and malnutrition should be considered for the interpretation of pretherapeutic CDA activity.

Abstract
Serum cytidine deaminase (CD) as a marker of inflammatory disease was assessed in 44 patients and 47 controls to differentiate polymyalgia rheumatica (PMR) from elderly onset rheumatoid arthritis (EORA). The patients were divided into four groups: PMR with and without synovitis and seropositive and seronegative EORA. No statistically significant differences were found when serum CD levels of seropositive EORA patients were compared with serum CD of PMR patients without synovitis, neither when serum CD levels of all PMR patients were compared with a seronegative EORA group, nor when serum CD levels of PMR patients with synovitis were compared with those with EORA. Nevertheless, statistically significant differences were detected between EORA's serum CD levels and the control group (p=0.023). This difference was 10% when comparing CD levels of PMR patients with the control group (p=0.070). We did not demonstrate that serum CD levels could be a useful tool to differentiate PMR from EORA, but these findings could nevertheless reflect the presence of an inflammatory disease.

Abstract
We evaluated serum total adenosine deaminase, its isoenzymes adenosine deaminase-1 and adenosine deaminase-2, and cytidine deaminase activities in 24 patients with active systemic lupus erythematosus, and in 26 healthy control subjects, and found the means +/- SD values to be 21.38 +/- 5.96 IU/l, 3.74 +/- 2.12 IU/l, 17.72 +/- 5.02 IU/l and 17.89 +/- 4.62 IU/l, respectively in the patients, and 14.97+/- 4.71 IU/l, 4.01 +/- 1.35 IU/l, 10.91 +/- 3.91 IU/l and 7.39 +/- 3.97 IU/l, respectively in the control subjects. When compared to the healthy controls, serum total adenosine deaminase, adenosine deaminase-2 and cytidine deaminase levels were significantly higher (p<0.001) in systemic lupus erythematosus patients, but the decrease of adenosine deaminase-1 level was not statistically significant (p>0.05). The increased adenosine deaminase-2 may be of macrophage origin. It closely correlated with clinical signs of active systemic lupus erythematosus. The membranes of polymorphonuclear neutrophils may be damaged, and cytidine deaminase may be released into serum. In conclusion, serum total adenosine deaminase, adenosine deaminase-2 and cytidine deaminase activities may serve as useful indicators for evaluating disease activity in patients with active systemic lupus erythematosus.

Abstract
We measured activities of some DNA turnover enzymes in 9 breast tissues with stage II cancer, 6 breast tissues with stage IIIa cancer, and 9 non-cancerous adjacent breast tissues from the same patients with stage II cancer. We found higher Adenosine Deaminase (ADA) and 5'-Nucleotidase (5'NT) and lower Guanase (GUA) activities in the cancerous tissues compared with the non-cancerous ones. No meaningful differences were however found between Cytidine Deaminase (CD) activities. Regarding the correlation analysis, positive correlations were established between ADA and 5'NT activities of the cancerous tissues (r = 0.45 for the tissues with stage II and r = 0.60 for the tissues with stage IIIa cancer). No meaningful correlations were however found between other enzyme activities. Relating to activity ratios, no meaningful differences were found between ADA/5'NT values in the tissues. GUA/CD ratios were however lower and the other ratios higher in the cancerous tissues. Results indicated that ADA and 5'NT activities increased and GUA activity decreased in the cancerous breast tissues but CD activities did not change in the tissues affected. It has been suggested that increased ADA and 5'NT together with decreased GUA activities might be a physiologic attempt of the cancer cells to provide more substrates needed by cancer cells to accelerate the salvage pathway activity. Furthermore, high ADA activity might also play part in the detoxication process of high amounts of toxic adenosine and deoxyadenosine substrates produced from accelerated purine metabolism in the cancerous tissues.

Abstract
The activities of some of the enzymes participating in nucleotide metabolism were measured in cancerous and noncancerous gastric tissues from patients with gastric cancer. The enzyme activities measured were found to be higher in the cancerous tissues than in the non-cancerous tissues. Adenosine deaminase (ADA), 5'-nucleotidase (5'-NT), guanase (GUA) and cytidine deaminase (CD) activities in the cancerous tissues were 56.0 +/- 24.0, 45.0 +/- 20.0, 0.34 +/- 0.16 and 4.65 +/- 2.04, respectively. The activities in non-cancerous tissues were 13.2 +/- 6.0, 19.8 +/- 8.3, 0.12 +/- 0.06 and 1.65 +/- 0.8, respectively. Cancerous tissues consisted of 7 gastric tissues with Grade I-II and 8 tissues with Grade III-IV adeno cancer. Non-cancerous adjacent tissues were obtained from the same patients with Grade I-II cancer. There were no meaningful differences between enzyme activities of the gastric tissues with Grade I-II and Grade III-IV cancer. Enzyme activity ratios indicates that ADA activity increased by the highest amount relative to other enzyme activities in the cancerous tissues. In the correlation analysis, we found positive correlations between some of the enzyme activities in the cancerous tissues. Results suggest that increased activities of these enzymes might play a part in the accelerated nucleotide metabolism in the cancerous gastric tissues.

Abstract
It is claimed that cytidine deaminase activity reflects local granulocyte turnover or activity in the synovial fluid of patients with rheumatoid arthritis, but cytidine deaminase is not a granulocyte specific enzyme. Lactoferrin is a granulocyte specific protein that is released from the secondary granulae during activation. We measured cytidine deaminase activity and lactoferrin concentrations in 33 rheumatic synovial fluid samples. Cytidine deaminase activity and lactoferrin concentrations correlated closely, indicating that both analyses reflect similar events in the joint-that is, result in their release from granulocytes. Cytidine deaminase activity and granulocyte concentrations correlated less closely, suggesting that there are additional factors besides the cell number which contribute to this release. Joint acidosis may be one such factor, as pH and cytidine deaminase activity correlated inversely. There was no association with synovial fluid proteoglycan concentrations, a marker of cartilage degradation.

Abstract
Circadian rhythm of serum cytidine deaminase and C reactive protein was assessed in 11 inpatients with rheumatoid arthritis who were crossed between 24 hours of bed rest and 24 hours of normal ward activity. Blood was taken at six hourly intervals and the results analysed by fitting sine waves with an assumed period of 24 hours to the measured concentrations. Cytidine deaminase after activity, but not at rest, showed circadian variation, with a 24 hour mean level of 17.4 units (normal 3-13 units) and an amplitude of 1.1 units. The circadian variation, defined as the curve's peak to trough difference as a percentage of the 24 hour mean, was 12.3% and occurred at 1208 hours. C reactive protein showed no significant circadian rhythm, in keeping with published findings. The timing of the peak in serum cytidine deaminase concentrations after a period of morning physiotherapy, but not during the bedrest morning, suggests that exercise accounts for the circadian rhythm, probably by increasing the lymphatic clearance from inflamed joints.
