Abstract: (2123 Views)
Background: Diffuse large B-cell lymphoma (DLBCL) is the most common type of non-Hodgkin's lymphoma (NHL), which is the most common type of lymphoma. NHL comprises a group of clinically and biologically diverse diseases, which range from indolent to aggressive clinical courses. Despite treatment advances in the last three decades with the use of combination immunotherapy, a significant fraction of patients relapses or are refractory to these treatments. Actually, there is no standard method for detection of recurrence. The purpose of this study was to evaluate the level of this enzyme in the patients with recurrent DLBCL compared to healthy controls.
Methods: In this randomized double-blind, placebo-controlled trial, the serum level of pyruvate dehydrogenase (PDH) enzyme in total of 26 patients with DLBCL recurrence in compare with 26 healthy individuals in the Sayed Al-Shohada Hospital, Isfahan University of Medical Sciences in Iran from September 2016 to September 2018, were assessed. The clinical data including age criteria, the Eastern Cooperative Oncology Group (ECOG) score rating, total bilirubin, alanine aminotransferase (ALT), aspartate aminotransferase (AST), prothrombin time and international normalized ratio (PT/INR), CT-scan, serum creatinine, platelet count, the absolute number of neutrophils, and the interval until the last treatment were gathered. After obtaining informed consent, blood samples were taken. and the PDH enzyme was measured in case and control groups.
Results: Fifty-three percent of patients were male and the mean age of participants in case and control groups was 37.2±17.3 and 34.8±8.9, respectively. Subsequently, the PDH levels were measured according to the enzyme protocol. The levels of enzyme in patients with relapse were significantly lower than normal ones (P=0.0003). The PDH serum level was also evaluated by age and sex, which did not show any significant differences (P=0.86).
Conclusion: In patients with relapsing B-cell lymphoma, the pyruvate dehydrogenase (PDH) enzyme serum levels were significantly lower than healthy subjects, but this difference was not related to age and gender. In the case of further studies and comparisons beyond this study, this enzyme could be a good candidate, used as an alternative diagnosis tool, in patients with recurrent lymphoma.
