Abstract:
Objective:To investigate the changes of T lymphocyte subsets and cytokines in children with he-patitis B virus(HBV)-associated glomerulonephritis (HBV-GN), and their relationship with HBV-DNA load.Methods:Forty-one children who was the first diagnosed with HBV-GN in Department of Pediatrics, the People′s Hospital of Gansu Province and Institute of Infectious Diseases, the First Hospital of Lanzhou University from September 2012 to September 2016 were collected as the objects(HBV-GN group). At the same time, the 40 patients with HBV infection (chronic HBV infection, normal liver and kidney function, normal 24-hour proteinuria quantitation, no hematuria under the microscope, no recent symptoms of cold and fever, etc.) were enrolled as the control group.The levels of T lymphocyte subset, tumor necrosis factor α(TNF-α), interferon-γ (IFN-γ), interleukin (IL)-2, IL-4, IL-6, IL-8 and IL-10 in the HBV-GN group and the control group were compared, and the relationship between HBV-DNA and cell factors was farther analyzed.Results:Compared with the control group, the proportions of CD3 + T, CD4 + T lymphocyte and CD4 + /CD8 + ratio decreased in the HBV-GN group(0.632±0.052 vs.0.692±0.047, 0.204±0.050 vs.0.466±0.038, 0.006±0.002 vs.0.017±0.003, t=1.025, 3.342, 5.234, all P<0.05), and the proportions of CD8 + T lymphocyte was significantly higher than that in the control group (0.411±0.023 vs.0.220±0.043, t=4.452, P<0.01). Besides, IL-2 and IFN-γ levels in the HBV-GN group were significantly lower than those in the control group[(23.36±2.55) ng/L vs.(36.33±1.24) ng/L, (19.20±2.18) ng/L vs.(61.25±2.08) ng/L, all P<0.05], and the serum levels of TNF-α, IL-4, IL-6, IL-8, and IL-10 were significantly higher than those in the control group[(19.60±1.46) ng/L vs.( 6.68±2.32) ng/L, (13.65±3.34) ng/L vs.(1.35±1.52) ng/L, (5.57±1.02) ng/L vs.(1.43±0.57) ng/L, (26.32±3.45) ng/L vs.(9.68±2.55) ng/L, (19.82±2.78) ng/L vs.(1.02±0.56) ng/L, all P<0.01]. Moreover, in HBV-GN patients, there was negative correlation between HBV-DNA load and IFN-γ, IL-2( r=-0.985, -0.943, all P<0.05), and positive relationship in HBV-DNA load with TNF-α, IL-4, IL-6, IL-8 and IL -10 levels( r=0.942, 0.966, 0.953, 0.944, 0.963, all P<0.05). Conclusions:There is an CD4 + /CD8 + imbalance and an abnormal level of cell factors in HBV-GN progression.In further HBV-GN treatment, HBV-DNA and the cell factors should be detected simultaneously to dynamically eva-luate the illness change and the clinical curative effect.
