Management of adverse effects associated with pegylated Escherichia coli asparaginase on coagulation in the treatment of patients with NK/T-cell lymphoma

Abstract

Natural killer/T-cell lymphoma (NK/TL) is a chemotherapy-sensitive disease, and asparaginase-based chemotherapy has become the standard primary treatment for patients with this malignancy recently. The objective of this study was to evaluate the adverse reactions on blood coagulation of the administered pegylated Escherichia coli (E coli) asparaginase (PEG-ASP) to the NK/TL patients. Clinical data of 71 NK/TL patients (range 13-73 years), who received 239 cycles of chemotherapy treatment containing PEG-ASP in the Hematology Department of Shanxi Province Cancer Hospital of China from January 2016 to December 2019 were analyzed retrospectively. Data of prothrombin time (PT), activated partial thromboplastin time (APTT), fibrinogen (FBG), and antithrombinIII (ATIII) were obtained at the time points routinely and statistically analyzed. There were statistical differences between the monitored parameters of baseline day0 (the day before use of PEG-ASP, named day0) and those of day3 (the 3rd day after treatment) to day6, and data showed all of the indicators could recover within 21 days. The events included PT prolonged in 33 patients (46.5%), APPT prolonged in 41 patients (57.7%, 20 patients with APTT >60 seconds), FBG decreased in 49 patients (69.0%, 12 patients with FBG <1 g/L), and ATIII decreased in 52 patients (73.2%). The patients' average number of cycles received was 2.3 for PT (>14 seconds), 2.5 for APTT (>35 seconds), 2.7 for FBG (<2 g/L), and 2.6 for D-dimer (>550 ng/mL). Compared with those at day0, PT and APTT prolonged sharply at day3 (P < .05), reached the peak at day12, maintained the prolonged level from day3 to day15, and gradually recovered at day 21. FBG and ATIII significantly decreased at day6 and day3 respectively (P < .05), both of them fell to the minimum at day12, and then returned the normal. The D-dimer levels were no significantly change during the whole treatment course. The APTT >60 seconds or FBG <1 g/L side effects were improved by symptomatic treatment of supplementation of fresh frozen plasma or cryoprecipitate infusion, no concomitant bleeding or thrombotic events emerging. Our data suggested although chemotherapy including PEG-ASP impacted moderately on the coagulation function of NK/TL patients, clinically monitored regularly were necessary and most NK/TL patients can complete the chemotherapy cycles successfully.

Diagnostic value of IL-22, IL-23, and IL-17 for NK/T cell lymphoma

“…Its main feature is the secretion of IL-17A. In addition, differentiated and mature Th17 also secretes several cytokines such as IL-6, IL-21, IL-22, IL-23, and so on, which mediate the production of inflammatory diseases (18,42,43). Recently, it is reported that the concentration of Th17 cells and related cytokines (IL-17, IL-22 and IL-23) are significantly increased in some tumors.…”
