title: [Study on using colloidal gold immuno-dot assay to detect special antibody of hemorrhagic fever renal syndrome].
abstract: OBJECTIVE
  To seek for a simple, sensitive and rapid assay to detect specific antibody of patients suffering from hemorrhagic fever renal syndrome (HFRS).
  
  
  METHODS
  Serum anti-HFRS IgM (sIgM) and IgG (sIgG) antibody were detected in 186 patients with HFRS using colloidal gold immuno-dot assay (CGIDA), and compared with those detected with enzyme linked immunosorbant assay (ELISA) and indirect fluorescent antibody test (IFAT). Kuhuang Shenmai injection (KHSM) combined Astragalus decoction (AD) treatment was applied to 101 HFRS patients in a treated group (n = 50), and the effect of therapy was compared with that in a control group (n = 51) treated with ribarvirin and ganlixin injection.
  
  
  RESULTS
  CGIDA showed positive sIgM antibody in 132 cases (70.9%) and positive sIgG antibody in 163 (87.1%) of the 186 HFRS patients. As compared the two groups in crossing stage, the rate of crossing shock stage in the treated group was higher than that in the control (P < 0.05). As for rate of crossing oliguria stage and from febrile stage directly developed into diuretic stage, the difference between the two groups was insignificant (P < 0.05).
  
  
  CONCLUSIONS
  CGIDA shows the merits of quick, simple and convenient in detecting sIgM and sIgG antibody in HFRS patients. The effect of KHSM combined AD treatment was not significantly different from that of ribarvirin and ganlixin injection.
