Aims/IntroductionAdipose tissue‐derived hormones are associated with metabolic disorders including type 2 diabetes mellitus. The present study investigated the levels of adiponectin and pro‐inflammatory cytokines including tumor necrosis factor‐α (TNF‐α), interleukin‐1 beta (IL‐1β) and IL‐10 in Vietnamese patients with type 2 diabetes mellitus, and their correlations with clinical parameters of overweight and type 2 diabetes mellitus.Materials and MethodsBased on body mass index, 73 patients with type 2 diabetes mellitus were categorized either as overweight or non‐overweight. As healthy controls, 57 overweight and non‐overweight individuals without type 2 diabetes mellitus were included. The adiponectin, TNF‐α, IL‐1β and IL‐10 levels were measured in the sera samples in all study participants by enzyme‐linked immunosorbent assay and were correlated with clinical parameters.ResultsThe adiponectin levels were lower in patients with type 2 diabetes mellitus (2.5 ± 1.5 μg/mL) compared with controls (16 ± 18.6 μg/mL; P < 0.0001), and were decreased in overweight individuals compared with those who were not overweight. The TNF‐α and IL‐1β levels were increased, whereas the IL‐10 levels were decreased in patients with type 2 diabetes mellitus and in overweight controls compared with non‐overweight controls (P < 0.0001). The adiponectin levels were correlated with the TNF‐α, IL‐1β, IL‐10 levels, and the clinical parameters of overweight and type 2 diabetes mellitus. The quantitative insulin sensitivity check index and homeostasis model assessment insulin resistance indexes were correlated with the relative ratios of adiponectin/TNF‐α, adiponectin/IL‐1β, adiponectin/IL‐10, TNF‐α/IL‐10 and IL‐1β/IL‐10.ConclusionsAdiponectin and pro‐inflammatory cytokines are associated with type 2 diabetes mellitus, and might serve as a prognostic marker and a therapeutic intervention for overweight‐related type 2 diabetes mellitus.

Quantification of plasma cell-free Epstein Barr virus DNA (cf EBV DNA) has been suggested as a promising liquid biopsy assay for screening and early detection of nasopharyngeal carcinoma (NPC). However, the diagnostic value of this assay is currently not known in the population of Vietnam, one of the countries which contributed the most to the NPC cases. Herein, we have reported a highly sensitive quantitative polymerase chain reaction (qPCR)-based assay targeting cf EBV DNA for the detection of NPC. A standard curve with linear regression, R 2 = 0.9961 (range: 25-150 000 copies/mL) and a detection limit of 25 copies/mL were obtained using an EBV standard panel provided by the Chinese University of Hong Kong. The clinical performance of this assay was assessed using plasma samples obtained from 261 Vietnamese individuals. The optimized qPCR assay detected cf EBV DNA in plasma with a sensitivity of 97.4% and a specificity of 98.2%. The absolute quantitative results of pretreatment cf EBV DNA and patient overall clinical stages were statistically correlated ( P < .05). In summary, the remarkably high sensitivity and specificity of our optimized qPCR assay strongly supports the wide use of cf EBV DNA quantification as a routine noninvasive method in early diagnosis and management of patients with NPC.
