BackgroundB cell chronic lymphocytic leukemia is one of the most frequent hematologic malignancies in the world. Cellular surface CD markers and serum Beta-2-microglobulin may be used as a prognostic tool in CLL patients.ObjectivesIn the present study we introduce serum adenosine deaminase as a diagnostic marker in CLL.Materials and MethodsBlood samples were collected from B-CLL and healthy subjects. White blood cell, red blood cell and platelet count and blood Erythrocyte sedimentation rate was recorded and serum Beta-2-microglobulin, Lactate dehydrogenase and total ADA enzyme activity were determined.ResultsSerum ADA activity was significantly higher in patients group than that of controls. ADA had a significant and direct correlation with B2M, WBC, LDH and ESR. However, there was not any relation between ADA and the stages of disease. Diagnostic cut-off, sensitivity and specificity of the serum ADA test were 27.97 U/L, 91% and 94%, respectively.ConclusionsA higher ADA activity in patients group and its correlation with CLL markers were seen in our study. High diagnostic value of serum ADA in our study suggests that it might be considered as a useful screening tool among the other markers in CLL.
The results demonstrated the high frequency of C allele of SLC2A1 HaeIII in Kurdish patients with diabetic nephropathy. It was also found that this polymorphism is a significant risk factor for diabetic nephropathy. The effect of this polymorphism on clinical and laboratory characteristics of diabetic nephropathy patients was significant.
Finding the effects of gene polymorphism on cancer pathogenesis is very desirable. The ATP-binding cassette is involved in drug metabolism, and the polymorphism of this gene may be an important risk factor in B cell chronic lymphocytic leukemia (B-CLL) or progression and/or response to chemotherapy agents. For the first time, the present study was aimed to evaluate the probable effects of ABCB1 T3435C polymorphism on clinical and laboratory features of Kurdish patients with B-CLL. This descriptive analytical case-control study was performed on 50 B-CLL patients and 100 healthy subjects. Serum levels of beta-2-microglobulin (B2M) and lactate dehydrogenase (LDH) and blood WBC, RBC, Plt and ESR were measured. The T3435C polymorphism of the ABCB1 gene was determined by PCR-RFLP. Concentration of serum and blood markers was significantly higher in the malignant group than in the benign subjects. The CC genotype had the highest frequency (66%) in the patient groups. There are no significant differences between the genotypes and type of treatment. Our results demonstrate the high frequency of C allele of ABCB1 T3435C in B-CLL patients with Kurdish ethnicity. We also show that this polymorphism has a significant risk factor in B-CLL. However, the effect of this polymorphism on clinical and laboratory characteristics of B-CLL patients was not significant.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
