[show abstract][hide abstract] ABSTRACT: To investigate the cystatin C levels in sera of patients with aggressive non-Hodgkin B-cell lymphoma.
The levels of cystatin C in sera of lymphoma patients and control group consisted of healthy individuals, were measured by using specific sandwich-type ELISA. For each patient the clinical stage of disease was determined according to Ann Arbor staging system for lymphomas.
Our study shows that mean cystatin C serum level in the patients group (1056 +/- 65 ng/mL) was significantly higher when compared with the mean level of the healthy control group (819 +/- 28 ng/mL) (P = 0.001). Mean cystatin C level of the group with clinical stages III and IV (1255 +/- 109 ng/mL) was significantly elevated when compared with the mean level of the group with clinical stages I and II (896 +/- 51 ng/mL) (P = 0.03).
This finding points out a connection between inhibitor level and aggressive behaviour of lymphoma and could be considered for further strategies of prognosis of the disease.
[show abstract][hide abstract] ABSTRACT: Chronic lymphatic leukemia (CLL) is the most frequent type of leukemia in western world, and a choice of treatment modality depends on current stage of disease. Clinical condition of patient considered as Binnet C stage, requires treatment. Standard polyhemiotherapy (FC protocol) does not always warrant adequate and satisfactory response. This case report reviews the patient with CLL in Binnet C stage, who did not respond on FC protocol in expected way, meaning, hematological and medullar response was not detected. Twelve weeks therapy of monoclonal antiCD52 antibody (MabCampath) was than applied, resulting in normalization of all parameters of disease activity, which was desired effect of the therapy. Administration of monoclonal antiCD52 antibody is justified in case of resistance on conventional previously applied means of therapy.
[show abstract][hide abstract] ABSTRACT: The concentration of cysteine protease inhibitor cystatin C was determined in sera from 59 patients with non-Hodgkin B-cell lymphoma using ELISA. The sera from 43 age and sex matched healthy blood donors served as controls. Cystatin C was significantly increased in sera of patients without therapy (mean 1136+/-SE 105.7ng/ml, p=0.00001) and with therapy (mean 1073+/-52ng/ml, p=0.001) compared to controls (mean 819+/-28ng/ml). The highest levels were determined in sera of patients with a relapse (mean 1680+/-196ng/ml). By using immunofluorescence staining and confocal microscopy we determined immature dendritic cells as a major population of cystatin C positive cells in affected lymph nodes. Our study reports for the first time that cystatin C is a potential marker for relapse in patients with non-Hodgkin B-cell lymphoma.
